Adjustable length cable

An adjustable length cable system that can be used in association with transmission of an axial pulling force. The cable system, which can be concealed within and/or behind a structure such as, for example, within an interior region of an entryway device, can accommodate adjustments in the axial lengths of a core wire and a conduit system of the cable system. The core wire can extend through, as well as beyond, the conduit system, and be connected to end fittings and/or connectors that can be used to transmit a pulling force to and/or from one or more components. In some embodiments, the conduit system can include an inner conduit telescopically coupled to an outer conduit such that the axial length of the conduit system is adjustable. Further, the relative axial positions of the inner and outer conduits may be retained by activation of a conduit locking device.

BACKGROUND

Embodiments of the present application generally relate to cables used to at least transmit an axial force. More particularly, but not exclusively, embodiments of the present application relate to adjustable length concealable cables that can be used in the transmission of an axial pulling or pushing force.

Cables, which can include wires, ropes, chains, and cords, among other devices, elements or apparatuses, can be utilized in a variety of different applications for transmitting an axial force between two or more components, including, but not limited to, the transmission of an axial pulling force. For example, in some applications, one or more cables may be used with exit devices of entryway devices, such as, for example, exit devices used to control the opening of doors and gates. For example, according to some applications, when a closed entryway device is to be displaced to an open position, a push bar of an exit device can be activated, such as, for example, by being depressed. Such linear displacement of the push bar can be translated to an axial force by a cable that, directly or indirectly, pulls on top and/or bottom latch(s) and/or latch bolt(s). Moreover, the cable(s) can transmit a pulling force on the latch bolt(s) that axially displaces the latch bolt(s) generally away from an extended, locked position in a door frame or adjacent wall, and to a retracted, unlocked position. Further, in at least some embodiments, the retracted latch bolt(s) may later be returned from the retracted, unlocked position to the extended, locked position, such as, for example, by a force provided by a biasing element, including but not limited to a spring. Such return of the latch bolt(s) to the extended, locked position can result in the latch bolt(s) axially pulling the cable(s) in a linear direction generally away from the exit device.

In such embodiments, the cable can be provided with a length that ensures the cable translates a pulling force to axially displace latch bolt(s) from the extended, locked position to the retracted, unlocked position with at least relatively minimal linear displacement of the push bar. Further, the cable can also be sized to have a length that prevents the cable from interfering with, or otherwise preventing, the latch bolt(s) from subsequently returning from the retracted, unlocked position to the extracted, locked position. Accordingly, in these and other applications, operation of the associated components, such as, for example, the exit device and latch bolt(s), can depend, at least in part, on the cable having a relatively precise and/or accurate length.

In at least some industries, to accommodate different characteristics of a system or particular installations, such cables may be offered in a variety of different lengths. For example, with respect to entryway devices, cables used to displace latch bolts are offered in a variety of lengths to accommodate a particular door height. Yet, such an approach often results in an installer maintaining an inventory of different length cables, which can in turn increase the cost and complexity of the associated installation. Further, in at least some situations, despite having the option of selecting from multiple cable lengths, some installations may require that the length of the cable be adjusted. Yet, such adjustments are often irreversible, which can, in at least some situations, prevent both subsequent adjustments in the length of the cable and fine tuning of the cable length, which can adversely impact the quality of the installation and operation of the associated component, device, or system.

FIG. 1illustrates a front perspective view of an exit device100, cable system102, and latch mechanisms or assemblies104a,104bthat are operably connected to an entryway device106, such as, for example, a door or gate, according to an embodiment of the present invention. The entryway device106may be constructed from a variety of different materials, including, for example, metal, wood, and composites, among other materials. The entryway device106includes at least two opposite edges, such as, for example, a top edge108aand a bottom edge108b. According to some embodiments, the exit device100may include a push bar110that is coupled to the top and bottom latch assemblies104a,104bby one or more cable systems102a,102b. In the illustrated embodiment, the top latch assembly104ais connected to a first cable system102a, and includes a latch bolt112that is configured to be displaced between an extended, locked position and a retracted, unlocked position. Similarly, when the bottom latch assembly104bis connected to a second cable system102b, and also includes a latch bolt112that is configured to be displaced between an extended, locked and a retracted, unlocked position. When in the extended, locked position, the latch bolts112of the top and bottom latch assemblies104a,104bmay extend into mating recesses in an adjacent structure, such as, for example, an adjacent recess in a door frame, wall, and/or floor, among other structures, so as to at least assist in locking or otherwise retaining the entryway device106in a closed position. Various different types of latch assemblies104a,104bcan be employed for the top and/or bottom latch assemblies104a,104b. Additionally, the top and bottom latch assemblies104a,104bcan be the same type of latch assembly, or may be different types of latch assemblies.

According to some embodiments, when the entryway device106is to be displaced from the closed position to an open position, the push bar110can be displaced, such as, for example, by linearly depressing the push bar by a user, which may in turn be translated into axial displacement of at least a portion of the cable systems102a,102bin a manner that may exert a pulling force on the latch assemblies104a,104b. Moreover, such axial displacement of at least a portion of the cable systems102a,102b, such as, for example, axial displacement of at least a core wire of the cable systems102a,102b, can be translated to an axial pulling force being exerting on the latches112and/or latch assemblies104a,104bthat is used to displace the latch bolts112from extended, locked positions to retracted, unlocked positions.

At least a portion of the exit device100, cable system(s)102a,102b, and latch assemblies104a,104bmay be positioned and/or concealed within an interior region114of the entryway device106, such as, for example, in one or more cavities or channels located in the entryway device106. For example, referencingFIG. 1, according to some embodiments, at least a portion of each cable system102a,102bmay extend along a channel, cavity, or void115, among or other areas, within the interior region114of the entryway device106.

For purposes of clarity,FIGS. 2A and 2Bdepict side views of opposite portions of an exemplary cable system102according to an illustrated embodiment of the present invention. As illustrated, the exemplary cable system102includes a conduit system103which can comprise a plurality of conduits116,118. For example, the conduit system103depicted inFIGS. 2A-2Ccan include a first, outer conduit116, and a second, inner conduit118. However, according to other embodiments, the conduit system can include more than two conduits116,118. The cable system102may also include a core wire120, a conduit locking device122, and an end fitting adapter124. As shown by at leastFIG. 3, the outer conduit116includes a first wall126having an outer surface128and an inner surface130, and extends from a first end132to a second end134of the outer conduit116. Further, the inner surface130of the first wall126generally defines an outer aperture136of the outer conduit116that is sized for a telescoping or coaxial sliding relationship with at least a portion of the inner conduit118along at least a portion of the outer conduit116. Further, according to some embodiments, the outer aperture136may extend along a central axis138that is arranged generally parallel with, if not co-axial with, a first central longitudinal axis140of the outer conduit116.

The first wall126of the outer conduit116, and more particularly, the outer and inner surfaces128,130of the first wall126, may have a variety of shapes and configurations, including, for example, having a cross sectional shape that is round, non-round, oval, square, rectangular, triangle, or trapezoidal, among other suitable shapes. Additionally, the shape of the outer surface128may be similar to the shape of the inner surface130, or can be similar in shape in only some areas. Further, the outer conduit116may be constructed from a variety of materials, including, for example, materials that may accommodate a restriction of a size of at least a portion of the outer aperture136when at least a corresponding portion of the first wall126is subjected to a clamping or radial compressive force by one or more fittings, and/or a material that can accommodate an expansion of the outer aperture136to accommodate the placement of one or more press fittings in the outer aperture136.

Similar to the outer conduit116, the inner conduit118includes a second wall142having an inner side144and an outer side146, and which extends from a first end148to a second end150along a second central axis152. Additionally, the outer side146of the second wall142of the inner conduit118can be configured to be received in the outer aperture136of the outer conduit116such that an axial position of the inner conduit118is adjustable relative to at least an axial position of the outer conduit116. Thus, according to some embodiments, at least a portion of the outer side146of the second wall142of the inner conduit118has a cross sectional size and/or that mates with the cross section size and/or shape of at least a portion of the outer aperture136of the outer conduit116. Additionally, the inner side144of the second wall142of the inner conduit118generally defines an inner aperture154of the inner conduit118that is sized to receive slideable displacement of at least a portion of the core wire120. Further, when inserted into the outer aperture136, the second central axis152of the inner conduit118may generally align with at least the central axis138of the outer aperture136.

A variety of different types of cables, wires, cords, strands, chain, lines, or ropes, among other devices or materials, having a length along a longitudinal axis156of the core wire120that is substantially longer than a corresponding width in a direction that is generally perpendicular to the longitudinal axis156, may be utilized for the core wire120. Further, the core wire120may be constructed from a variety of different materials, including, but not limited to, a braided or non-braided steel, metal, and non-metallic cable(s) or wire(s). Further, according to some embodiments, the core wire120may be coated, at least along an outer surface158of the core wire120, with a vinyl material, among other coatings or materials. The core wire120may be sized to extend from a first end160to a second end162(FIGS. 7 and 8A) along the longitudinal axis158of the core wire120. Additionally, at least a portion of the core wire120has a width that can accommodate placement of the core wire120in at least a portion of the inner aperture154of the inner conduit118.

The conduit locking device122is adapted to selectively lock the relative positions of the outer and inner conduits116,118. For example, once the relative axial positions of the outer and inner conduits116,118are selected, the conduit locking device122is adapted to provide one or more forces that at least attempt to prevent subsequent axial displacement of the inner conduit118relative to the outer conduit116, or vice versa. A variety of different types of fittings may be employed for the conduit locking device122, including, for example, fittings that may provide a clamping force for one or both of the outer and inner conduits116,118.

The exemplary conduit locking device122depicted inFIG. 4includes mating first and second locking segments164,166, with both the first and second locking segments164,166having inner walls168a,168bthat generally define orifices170a,170bthat extend through the first and second locking segments164,166and which are sized to at least accommodate passage of at least the inner conduit118through the conduit locking device122. The exemplary first locking segment164depicted inFIG. 4includes opposite first and second extensions172a,172bthat are separated from one another by a shoulder section174. According to the depicted embodiment, the first extension172ais sized relative to the outer aperture136of the outer conduit116, or vice versa, such that at least a portion of the first extension172amay be retained in the outer aperture136via a press, interference, and/or friction fit between the first extension172aand the adjacent first wall126of the outer conduit116. According to the illustrated embodiment, an outer portion176of the first extension172amay include one or more barbs178that can be structured to facilitate placement of the first extension172ainto the outer aperture136, as well as assist in the formation of the press, interference, and/or friction fit and/or otherwise assist in the retention of the engagement between the first extension172aand the inner surface130of the first wall126of the outer conduit116.

A first side180aof the shoulder section174of the exemplary first locking segment164depicted inFIG. 4is sized to abut against, or be in relative close proximity to, at least the first end132of the outer conduit116such that at least a portion of the shoulder section174may enter into the outer aperture136. For example, according to the depicted embodiment, at least a portion of the shoulder section174may have a size, such as, for example, a diameter, that is larger than a corresponding size of the outer aperture136, and in at least some embodiments is larger than a corresponding size of at least the adjacent portion of the outer surface128of the first wall126of the outer conduit116. Further, an opposite second side180bof the shoulder section174can provide a surface against which the second locking segment166of the conduit locking device122can abut, at least in some situations, when the second locking segment166is operably coupled to the first locking segment164. For example, according to the depicted embodiment, the second side180bmay have a tapered or chamfered orientation that can mate with or provide clearance for an adjacent tapered or chamfered surface182of the second locking segment166.

The second extension172bof the first locking segment164is structured for mating and/or locking engagement with the second locking segment166of the conduit locking device122. For example, according to some embodiments, the second extension172bmay have an internal or external thread that is adapted for a mating threading engagement with an external or internal thread of the second locking segment166of the conduit locking device122. For example, according to the embodiment depicted inFIG. 4, the second extension172bincludes an external thread that mates with an internal thread in the orifice170bof the second locking segment166of the conduit locking device122.

The second extension172bof the first locking segment164may further include a first compression segment184that is sized for a compressive engagement with a mating second compression segment186of the second locking segment166of the conduit locking device122. For example, according to the depicted embodiment, the first compression segment184and second compression segment186may have mating conical, angled, chamfered, or tapered configurations. According to such configurations, which can include a collet configuration, the second compression segment186can engage the first compression segment184in a manner that facilitates the formation of a radial force that generally inwardly displaces, deflects, deforms, and/or otherwise bends the first compression segment184against a portion of the inner conduit118in a manner that generally secures the inner conduit118to at least the first locking segment164of the conduit locking device122. Moreover, in the depicted embodiment, as the relative axial positions of the first and second locking segments164,166are adjusted by the threaded engagement between the external thread of the second extension172bof the first locking segment164and the internal thread of the second locking segment166such that the second locking segment166is moved into closer proximity to the shoulder section174, the size of the space, such as diameter, between the portions of the second compression segment186that is engaging the first compression segment184may decrease, thereby exerting a radial force on the first compression segment184that is translated to a compression or clamping force on the inner conduit118. Accordingly, when the relative axial positions of the outer and inner conduits116,118are selected, such as, for example, by the selection of the axial distance or length that the inner conduit118is to extend out of the outer conduit116, the compression or clamping force exerted by at least the first locking segment164of the conduit locking device122on the inner conduit118, as well as the press, interference, or friction fit of the first locking segment164of the conduit locking device122to the outer conduit116, may generally lock or restrain the relative axial positions of the outer and inner conduits116,118.

The conduit locking device122can have a variety of other configurations in addition to the embodiment of the conduit locking device122depicted inFIG. 4. For example,FIGS. 5A and 5Billustrate a conduit locking device400that provides a frictional clamp for securing the relative location of the outer and inner conduits116,118. According to the illustrated embodiment, the conduit locking device400includes a first locking segment402, a second locking segment404, and a clamping body406.

The first locking segment402includes a sidewall408that has an inner surface410and an outer surface412. The inner surface410defines a passageway414in the first locking segment402, and can include a first portion416and a second portion418. The first portion416of the inner surface410is sized, such as, for example, with a diameter, so that at least the portion of the passageway414adjacent to the first portion416is configured to receive insertion of at least a portion of the outer conduit116, such as, for example, an end portion of the outer conduit116. Further, according to some embodiments, the sidewall408can be configured such that a force can be applied sidewall408that is used to clamp or otherwise crimp a portion of the first portion416of the inner surface410to a portion of the outer conduit116that is positioned within the passageway414of the first locking segment402.

The second portion418of the inner surface410of the first locking segment402generally defines a passageway414that has a size, such as, for example, a diameter, that can accommodate passage of the inner conduit118, but not the outer conduit116, through at least the portion of the passageway414adjacent to the second portion418of the first locking segment402. Further, as discussed below, according to the illustrated embodiment, the second portion418includes a first tapered region420that is configured to engage and exert a generally inward force against the clamping body406.

Similar to the first locking segment402, the second locking segment404includes a sidewall422that has an inner surface424and an outer surface426. The inner surface424generally defines a passageway428of the second locking segment402that is sized to accommodate at least passage of a conduit, such as, for example, the inner conduit118, through the second locking segment404. According to some embodiments, the inner surface424of the second locking segment404can include a first portion430that generally defines a size of the passageway428, such as, for example, a diameter, that is similar to that of the inner conduit118, while the second portion432generally defines a size of the passageway428that can receive at least a portion of the clamping body406. The second portion432of the inner surface424can generally extend to a shoulder434which, according to the illustrated embodiment, can be positioned between the first and second portions430,432of the inner surface424.

The clamping body406can have a sidewall436that generally defines an inner passage438of the clamping body406. The inner passage438can be sized to receive insertion of at least the inner conduit118. According to the illustrated embodiment, at least a portion of the outer surface440of the sidewall436can correspond to a similar size, such as diameter, of the passageway428in the region of the second portion432of the inner surface424of the second locking segment404. Moreover, the clamping body406can be sized to be positioned at least in the portion of the passageway428that is generally defined by the second portion432of the inner surface424of the second locking segment404.

The outer surface of the clamping body406can also include a second tapered region442that is configured to matingly engage the first tapered region420of second portion418of the first locking segment402. Accordingly, when the clamping body406and at least a portion of the first tapered region420of the first locking segment402are positioned in the passageway428of the second locking segment404in the region of the second portion432of the inner surface424, the first tapered region420of the first locking segment402can be brought into pressing engagement with the second tapered region442. Additionally, linear movement of the clamping body406in a direction away from the first tapered region420can be limited or prevented by the shoulder434. As the first locking segment402continues to be at least linearly displaced relative to at least the clamping body406so that at first tapered region420is at least linearly displaced relative to the second tapered region442, a resulting pressing engagement between the first tapered region420and the second tapered region442can result in at least a portion of the clamping body406being bent, deformed, and/or displaced so as to decrease a size, such as diameter, of the inner passage438of the clamping body406. Moreover, such a pressing engagement between the first tapered region420and the second tapered region442can result in the clamping body406being clamped or locked onto at least a portion of the inner conduit118in the inner passage438, which can at least assist in preventing relative movement between the outer and inner conduits116,118.

Further, such pressing engagement between the first tapered region420and the second tapered region442can also facilitate a pressing engagement between the outer surface412of the sidewall408of the first locking segment402and the inner surface424of the sidewall422of the second locking segment404that secures the relative positions of the first and second locking segments402,404, as well as secures the relative positions of the outer and inner conduits116,118. Optionally, according to some embodiments, the first and second locking segments402,404can be threadingly engaged such that, as the first or second locking segment402,404is rotatably displaced relative to the other of the first and second locking segments402,404, at least the first tapered region420is at least linearly displaced relative to the second tapered region442in a manner that facilitates the clamping or locking of the clamping body406to the inner conduit118, which can in turn at least assist in preventing relative movement between the outer and inner conduits116,118.

Additionally,FIG. 6illustrates an example of a conduit locking device122′ in the form of one or more clamps188. More specifically, according to some embodiments, the clamp188can include first and second clamp portions189a,189b, such as, for example, a pair of spring or hose clamps. The first clamp portion189acan be configured to be positioned about the first wall126of the outer conduit116such that the first clamp portion189acan provide a compressive force against the first wall126, which can be, in at least some embodiments, translated to a force against at least an adjacent portion of the second wall142that is positioned at least within the outer aperture136. The second clamp portion189bof the spring clamp189bcan be positioned about, and sized to exert a compressive force against, the second wall142of the inner conduit118. Further, the compressive forces exerted by the first and second clamp portions189a,189bagainst at least the outer and inner conduits116,118, respectively, may be sufficient to at least resist axial displacement of the first and second clamp portions189a,189balong the associated first and second walls126,142. Further, the axial position of the first clamp portion189arelative to the second clamp portion189bmay be relatively fixed by an arm191that axially extends between, and couples together, the first and second clamp portions189a,189b.

According to some embodiments, each of the first and second clamp portions189a,189bmay include at least one outer protrusion and at least one inner protrusion. When the position of the clamp188relative to the outer and inner conduits116,118is to be adjusted, a force may be exerted to bring one or more of the outer protrusions190ainto closer relative proximity to one or more of the adjacent inner protrusions190b, thereby at least temporarily increasing a size of the associated first or second clamp portion189a,189b, such as, for example, a size of an inner aperture193a,193bof the associated first or second clamp portion189a,189b. According to such an embodiment, the size of the first and second clamp portions189a,189bmay be increased such that the clamp188may be axially displaced along the cable system102to a position in which the force on the spring clamp188may be released or reduced such that the first and second clamp portions189a,189bcan exert compressive forces on at least the adjacent outer and inner conduits116,118to secure the relative positions of the outer and inner conduits116,118. Alternatively, according to other embodiments, the first and second clamp portions189a,189bmay include a worm drive that engages teeth or recesses along an outer surface195a,195bof the first and second clamp portions189a,189b, respectively, such that rotational displacement of the worm drive in one direction can reduce the size of the associated aperture193a,193b, while rotation in an opposite direction can increase the size of the associated aperture193a,193b. While the exemplary embodiments shown inFIGS. 5A-6illustrates a particular types of conduit locking devices, a variety of other devices may be employed, including, but not limited to, a quick release clamp, a compression fitting, or a quick release stem clamp, among other suitable clamps.

ReferencingFIGS. 2A-2C and 7, according to some embodiments, the second end134of the outer conduit116, and the opposite first end148of the inner conduit118may each be coupled to a conduit adapter190that is structured to secure an axial position of at least a portion of the cable system102. For example, according to some embodiments, the conduit adapters190may be configured as latch adapters that secure one of the first end132of the outer conduit116and the second end150of the inner conduit118to, or in relatively close proximity to, a latch assembly104a,104bor an associated or nearby bracket or housing, and the other of the first end132of the outer conduit116and the second end150of the inner conduit118to an exit device100or associated or nearby bracket or housing. Additionally, the conduit adapter190can include an adapter orifice192sized to accommodate passage of the core wire120through the conduit adapter190.

ReferencingFIG. 7, according to some embodiments, the conduit adapter190may have opposite first and second sections194a,194b, the first section194abeing structure to be securely coupled to the first end132of the outer conduit116and/or the second end150of the inner conduit118, such as, for example, by a mechanical connection, including a pin, screw, or bolt, by a compressive force, such as, for example, by a clamp, and/or by a press, interference, or friction fit. For example, according to the embodiment depicted inFIG. 7, the first section194amay be sized for a press, interference, or friction fit in the outer aperture136of the outer conduit116and/or the inner aperture154of the inner conduit118. Further, similar to the above-discussed first extension172a, the first section194acan include one or more barbs196, which can be structured to facilitate the placement of the first section194ainto the outer aperture136and/or inner aperture154, assist in the formation of the press, interference, and/or friction fit, and/or assist in the retention of the engagement between the conduit adapter190and the first and second wall126,142of the associated outer or inner conduit116,118.

The conduit shoulder section198of the conduit adapter190is sized to at least abut against at least the adjacent end132,150of the corresponding outer or inner conduit116,118such that at least a portion of the conduit shoulder section198does not, or cannot, enter into the associated outer or inner aperture136,154. For example, according to the depicted embodiment, at least a portion of the conduit shoulder section198may have a size, such as, for example, a diameter, that is larger than a corresponding size of the outer aperture136, and, in at least some embodiments, is larger than a corresponding size of at least the adjacent outer or inner aperture136,154. Further, an opposite side of the conduit shoulder section198can assist in retaining an axial position of the cable system102when the cable system102is operably connected to an entryway device106, exit device100, latch assembly104a,104b, and/or associated housings, walls, and/or brackets. For example, according to some embodiments, a portion of the second section194bof the conduit adapter190may include an engagement area200that is configured, such as, for example, to be received in an groove, slot, or other opening in a portion of a latch assembly104a,104bor exit device100, and which is not sized to receive the conduit shoulder section198or a section protrusion202on an opposite side of the engagement area200. For example, according to some embodiments, the conduit shoulder section198and section protrusion202may generally have sizes, such as diameters, among other shapes and sizes, that prevent the conduit shoulder section198and section protrusion202from entering into the groove, slot, or other opening in a portion of a latch assembly104a,104b, exit device100, or associated bracket or housing that is sized to receive the engagement area200of the second section194b. Further, according to some embodiments, the engagement area200may be a recessed or smaller sized portion of the second section194b, with the section protrusion202being generally created by a difference in the size and/or shape between the engagement area200and an adjacent portion of the second section194b.

At least a portion of the core wire120may extend beyond the conduit aperture102in the conduit adapter190such that the core wire120may be selectively trimmed to accommodate further adjustment to the axial length of the cable system102. Moreover, a portion of the core wire120may extend from the conduit adapter in an axial direction away from the outer an/or inner conduit116,118such that the axial length of the core wire120may be adjusted to accommodate the size of a particular of the entryway device and/or distance between the exit device100and associated latch assembly(ies)104a,104bin which the cable system102may be employed. Optionally, according to some embodiments, when the axial length of the core wire120is determined, such as, for example, determined during installation of the cable system102in or about an entryway device106, excess portion or length of the core wire120may be removed or trimmed, such as, for example, by cutting of the core wire120. The length of core wire120that is to be cut from the core wire120may be determined during installation of the cable system102in a number of a manners, including, for example, through the use of a guide or spacer that may indicate the length of core wire120that is to extend beyond a reference location, including, but not limited to, from an end132,134,148,150of one or both of the outer and/or inner conduits116,118, or from an adjacent conduit adapter190, among other reference positions.

ReferencingFIG. 7, one or more opposite ends160,162of the core wire120may be secured to an end fitting adapter124that may be structured to couple the core wire120to a latch bolt112, latch assembly104a,104b, and/or exit device100. For example, according to the illustrated embodiment, both ends160,162of the core wire120are coupled to an end fitting adapter124. The end fitting adapters124can be adapted to be secured to the core wire120in a number of different configurations. For example,FIG. 7illustrates a collet style end fitting adapter124including a first fitting portion204and a second, mating fitting portion206. The first fitting portion204includes a cavity208that is generally defined by an inner wall210and which is sized to receive placement of at least an end160,162of the core wire120. A first compression wall212positioned about an outer portion of the fitting portion204and extending over at least a portion of the inner wall210can be configured for engagement with a mating second compression wall214in an aperture216of the second fitting portion206. Such engagement between the first and second compression walls212,214may be configured to facilitate formation of a radial compressive force that generally inwardly displaces, deflects, deforms, and/or otherwise bends at least a portion of the first fitting portion204toward the core wire120in the cavity208in a manner that exerts a compressive force against the core wire120, and which secures at least the first end fitting adapter124to the core wire120. Moreover, according to the embodiment depicted inFIG. 7, the first and second fitting portions204,206may be arranged to provide compressive forces on the core wire120via a collet type engagement between the first and second compression walls212,214. According to such an embodiment, the first and second compression walls212,214may have conical, tapered, angled, or chamfered configurations that may at least assist in facilitating formation of a compressive force on at least a portion of the core wire120that is positioned in the cavity208of the first fitting portion204. Further, according to some embodiments, the end fitting adapter124may be configured to retain a locking engagement with the core wire120of up to around 100 pounds-force (lbf).

Attaining compressive engagement between the first and second compression walls212,214of the exemplary end fitting adapter124depicted inFIG. 7may be further facilitated by a mating threaded engagement between the first and second fitting portions204,206. For example, according to some embodiments, the first fitting portion204may include an external thread that engages an internal thread of the second fitting portion206. According to such an embodiment, at least as one of the first and second fitting portions204,206is rotated relative to the other of the first and second fitting portions204,206, and the relative axial position of the first and second fitting portions204,206may be adjusted in a manner that facilitates engagement of the first and second compression walls212,214. The threaded engagement between the first and second fitting portions204,206may continue to be utilized to adjust the relative axial positions of at least the first and second compression walls212,214so as to increase the compressive force that is translated to at least a portion of the core wire120positioned in the cavity208, and thereby securely retaining engagement of the end fitting adapter124to the core wire120.

According to some embodiments, the end fitting adapter124can also include a connector218that is sized and shaped to engage a mating lug or connector of the exit device100, the latch assembly104a,104b, or the latch bolt112. For example, according to some embodiments, the connector218′ is configured as a T-shaped or spherical shaped connector, among other suitable connector configurations. Additionally, according to some embodiments, the connector218may be directly coupled to or extend from the core wire120, such as, for example, being clamped or welded to the wire cable120, among other types of connections or fasteners. Further, according to some embodiments, the end fitting is a collet style end fitting adapter124that includes a collet insert which translates compressive forces to the core wire120so as to securely retain or lock the core wire120in engagement with the end fitting adapter124. According to such an embodiment, the first fitting portion204includes a compression wall that engages a compression wall of the collet insert in a manner that can reduce the size of a cavity of the collet insert in which a portion of the core wire120is positioned, and thereby compressing the core wire120against an inner surface of the collet insert. Additionally, the collet insert may include features that facilitate a gripping force which may assist in retaining the core wire in a locking or otherwise relatively secure engagement with at least the collet insert. For example, according to some embodiments, portions of the inner surface of the collet insert may be separated, such as being raised or lowered, from other portions of the inner surface to provide teeth or gripping areas of the inner surface of the collet insert that may assist in retaining engagement of at least the collet insert to the core wire120. Further, similar to the end fitting adapter124depicted inFIG. 7, according to such an embodiment, operable engagement between the collet insert and the first fitting portion may be facilitated by adjustment of the axial position of the associated first fitting segment relative to the collet insert and the second fitting segment via a threaded engagement between an external thread of the first fitting portion and an internal thread of the second fitting segment.

FIGS. 8A-8Cillustrate a cable system in which the core wire120′ includes a plurality of beads234spaced apart from adjacent beads234and which extend outwardly along at least a portion of an axial length of the core wire120′. The beads234may be adapted to engage the end fitting adapters124′ on either end of the cable system in a manner that may at least assist in retaining the end fitting adapter124′ in relatively locking engagement with the core wire120′ and/or assist in translating an axial pulling force from the core wire120′ to the end fitting adapter124′. According to some embodiments, the first fitting portion204′ of the end fitting adapter124′ includes a pocket236in communication with the cavity208′ of the first fitting portion204′, and which is sized to receive placement of a bead234. Additionally, according to some embodiments, the pocket236may extend through an outer wall238of the first fitting portion204′. Accordingly, excess core wire120′ that can be trimmed, as previously discussed, can be trimmed such that a bead234may be positioned within the pocket236. Further, the pocket may generally terminate at an end wall240positioned between the bead234that is received in the pocket236and an opening240of the cavity208′, and which is sized to abut against the bead234at least when the core wire120′ exerts a pulling force on at least the first fitting portion204′.

WhileFIGS. 7-8Care discussed above in terms of a threaded collet style end fitting adapters124,124′, it should be understood that a variety of other mechanisms may be used to lockingly couple an end fitting adapter to the core wire120. For example,FIG. 9illustrates a clamp244which can include, but is not limited to, a one-way clamp, which may be lockingly secured to the core wire120as well as coupled, directly or indirectly, to the connector218. According to such an embodiment, the clamp244can include a body portion246having a passageway248sized to receive passage of at least a portion of the core wire120. The clamp244can further include a finger portion250that is biased by a biasing element252, such as, for example, a spring, toward a side, such as a first side254, of the passageway248. According to such an embodiment, with a portion of the core wire120extending through the passageway248between the first side254of the passageway248and the finger portion250, the biasing element252may exert a force on the finger portion250that displaces the finger portion to a locked position in which the finger portion presses the adjacent portion of the core wire120between the finger portion250and the first side254of the passageway248. Further, according to some embodiments, the clamp244may be configured as a one-way clamp244in which the finger portion250and/or biasing element252may be retracted away from the locked position by axial displacement of the core wire120in one, and only one, axial direction. According to such an embodiment, the clamp244may be oriented such that the core wire120is prevented from being pulled through the clamp244when the core wire120exerts a pulling force on the clamp244during at least operation of the associated latch assembly104a,104b.

FIGS. 10A and 10Billustrate a cross sectional view and a side perspective view, respectively, of an exemplary end fitting500for use with any of the embodiments and variations of the cable systems100discussed herein. Further, features discussed with respect to the end fitting500illustrated inFIGS. 10A and 10Bcan be used with other features of end fittings, and/or related components, that are also disclosed herein, including, for example, end fittings and/or related components depicted in at leastFIGS. 2B, 2B, 4A, 7, 8A and 8B.

As illustrated inFIGS. 10A and 10B, the end fitting500includes mating first and second locking segments502,504. The first and second locking segments502,504are structured for selectable mating engagement, such as, for example, by a threaded engagement therebetween, among other types of suitable secure or locking engagements. According to the illustrated embodiment, the first locking segment502has a sidewall506including an inner portion508and an outer portion510, with the inner portion508generally defining an inner region512of the first locking segment502. According to the illustrated embodiment, the sidewall506can have an internal or external thread that mates with a corresponding external or internal thread of the second locking segment504. For example, according to the illustrated embodiment, the inner portion508of the sidewall506of the first locking segment502can include an internal thread that mates with an external thread of the second locking segment504.

At least a portion of the inner region512of the first locking segment502can be further defined by an upper wall514that can extend across at least a portion of the sidewall506and/or the inner region512. Further, similar to at least some of the previously discussed connectors218, a connector516, such as, for example, a T-shaped or spherical shaped connector, among other suitable connectors, can extend from a side of the upper wall514such that the connector516and the inner region512are arranged on opposite sides of the upper wall514. As shown inFIGS. 10A and 10B, according to some embodiments, the connector516can include a first portion518and a second portion520, with the second portion520separating the first portion518from the upper wall514. Moreover, the second portion520can be sized to provide a space or clearance between the first portion518and the upper wall514to accommodate receipt of the first portion518in, or otherwise engaged with, a mating lug or connector522of the exit device100, the latch assembly104a,104b, or the latch bolt112.

According to some embodiments, at least a portion of the inner region512can be occupied by or comprise at least a portion of a clamping segment524. For example, according to some embodiments, the clamping segment524may comprise a portion of a unitary or monolithic first locking segment502. For example, the clamping segment524can be attached to and/or extend from the sidewall506and/or the upper wall514of the first locking segment502. According to such an embodiment, the unitary nature of the first locking segment502can result in the clamping segment524being moved with the other portions of the first locking segment502as the first locking segment502is at least linearly displaced along the core wire120. Alternatively, according to other embodiments, the clamping segment534is a separate component that is received in the inner region512of the first locking segment502. According to such embodiments, some movements of the first locking segment502, such as, for example, linear movement of the first locking segment502toward the second locking segment504, can result in at least a portion of the first locking segment502that defines, and/or is positioned in, the inner region512engaging the clamping segment524in manner that results in the clamping segment524being moved in at least a similar linear direction along the core wire120.

According to the illustrated embodiment, at least the upper wall514and a portion of the connector516can include an orifice526in communication with at least the inner region512of the first locking segment502. Moreover, the first locking segment502can be structured such that a core wire120can extend into the inner region512through an opening of the inner region512, pass through the orifice526, and exit from the inner region512through another opening in the first locking segment502. For example, in the illustrated embodiment, the orifice526extends through the clamping segment524, the upper wall514, and the first and second portions518,520of the connector516. Further, according to some embodiments, the orifice526can be generally aligned with a central longitudinal axis528of the first locking segment502, the second locking segment504, the inner region512, the clamping segment524, and/or the connector516.

The second locking segment504includes a sidewall530, with an inner portion532of the sidewall530generally defining an interior region534of the second locking segment504. According to the illustrated embodiment, an exterior side536of the sidewall530includes a male threaded region that is configured to mate with an internal thread of the first locking segment502. The interior region534can be sized to at least accommodate passage of the core wire120through the second locking segment504, as well as receive placement of at least a portion of the clamping segment524. According to the illustrated embodiment, a portion of an inner portion532of the sidewall530is inwardly tapered, as shown inFIG. 10B, thereby providing a tapered region538. At least a portion of the tapered region538is sized to receive insertion of the clamping segment524. Further, according to some embodiments, at least a portion of the outer surface540of the clamping segment524can include a tapered configuration similar to the tapered region538of the inner portion532of the second locking segment504. According to the illustrated embodiment, as the clamping segment524linearly progresses into the interior region534of the second locking segment504, the clamping segment524can engage portions of the tapered region538in which a size, such as diameter, of the tapered region538is smaller than the corresponding size of the outer surface540of the clamping segment524. In such instances, an inward force can be exerted against the clamping segment524which can cause deformation, bending, and/or deflection of at least a portion of the clamping segment524. Moreover, exertion of such force against the clamping segment524can cause a reduction in a size of an opening542that extends through the clamping segment524and which is sized to receive the core wire120. Such restriction in the size of the opening542of the clamping segment524can cause the clamping segment524to exert a clamping or locking force against the core wire120in the opening524, which can in turn secure the clamping segment524, as well as the associated engaged first and second locking segments502,504, at a selected position along the core wire120, as shown inFIGS. 10A and 10B.

During use, the core wire120can extend through the interior region534of the second locking segment504, the opening542of the clamping segment524, and through the orifice526and the inner region512of the first locking segment502so as to accommodate linear displacement of each of the components of the end fitting500relative to the core wire120. Accordingly, during installation, the first and second locking segments502,504can be adjustably displaced along the core wire120until the first and second locking segments502,504are positioned at a selected position relative to the core wire120. The selected location for positioning of the end fitting500relative to the core wire120before the relative position of the end fitting500is lockingly secured can be determined in a variety of manners, including, for example, by placement of a spacer between the end fitting500and the adjacent conduit116,118. With the first and second locking segments502,504located at selected positions, the first and second locking segments502,504can be engaged, if not already engaged, in a manner that clamps the clamping segment524to the core wire120, such as, for example, via use of the threaded engagement between the first and second locking segments502,504, as previously discussed.

Such engagement between the first and second locking segments502,504can reduce an overall length of the end fitting500, which can in turn result in the clamping segment524entering and/or being further displaced into the tapered region538of the second locking segment504. As the clamping segment524is further displaced into the tapered region538, forces exerted against the clamping segment524that enable the position of the clamping segment524, and moreover the position of the assembled end fitting500, to be secured relative to the core wire120. Further, according to some embodiments, the first and second locking segments502,504can include features configured to engage tools, such as a hexagonal shape, that can assist in the secure engagement of the first locking segment502to the second locking segment504, and moreover can assist in displacing the clamping segment524into a tapered region538of the second locking segment504so as to provide a secure, locking engagement of the end fitting500with the core wire120. Additionally, when the end fitting500is eventually positioned at the selected or final position, such as, for example, when no adjustment or further adjustment is deemed necessary, excess core wire120extending out from the connector516can be cut or trimmed.

It is contemplated that, according to some embodiments, in the event that the position or angular orientation of the secured end fitting500relative to at least the core wire120is to be adjusted, the engagement between the first and second locking segments502,504can be correspondingly adjusted, such as by loosening, so that the clamping segment524can be moved to a position relative to the tapered region538which decreases the force exerted at least by the clamping segment524on the core wire120to a degree that can again accommodate linear displacement of the end fitting500relative to the core wire120. When the end fitting500is re-positioned to another linear and/or rotational position relative to the core wire120, the engagement between the first and second locking segments502,504can be adjusted, such as by tightening, so that the clamping segment524is positioned in the tapered region538at a location in which at least the clamping segment524exerts a force sufficient to maintain the relative position of the end fitting500relative to the core wire120.

While some embodiments of the end fitting500are discussed above, it should be understood that the end fitting500can have a variety of other suitable configurations or modifications. For example, according to some embodiments, the clamping segment524can be part of, or received in, the second locking segment504, while the tapered region538can be part of the first locking segment502, among other possible variations.

FIG. 11illustrates a schematic flow diagram of an exemplary process300of adjusting an axial length of the cable system102,102′. The illustrated operations for all of the processes in the present application are understood to be exemplary only, and operations may be combined or divided, and added or removed, as well as re-ordered in whole or in part, unless explicitly stated to the contrary.

At step302, a length of the core wire120,120′ is selected. According to some embodiments, the selected core wire120,120′ length may be based, at least in part, on the length of the portion of the core wire120,120′ that is to extend beyond the outer and/or inner conduit116,118, also referred to as a core wire extension length, as indicated by L1inFIG. 2. Further, according to some embodiments, the core wire120,120′ can be cut or otherwise trimmed to a selected axial length at a location that is in relative close proximity to a bead234, if a bead234is present. At step304, the bead234, if any, is positioned in the pocket236of the end fitting adapter124′. At step306, the end fitting adapter(s)124,124′ is/are lockingly secured to the core wire120,120′, such as, for example, by tightening the threaded collet style end fitting adapters120,124′ depicted in at leastFIGS. 7-8Cor the clamp244ofFIG. 9, among other locking mechanisms. At step308, the relative axial positions of the outer and inner conduit sections116,118can be set for the selected length of the core wire120,120′ and/or the selected core wire extension length. At step310, the conduit locking device122can be actuated to prevent and/or eliminate relative motion between the outer and inner conduit sections116,118.

FIG. 12also illustrates a schematic flow diagram of an exemplary process350of adjusting an axial length of the cable system102,102′. At step352, the relative axial positions of the outer and inner conduits116,118may be selected. At step354, the conduit locking device122may be actuated so as to lock or otherwise generally secure the relative axial positions of the outer and inner conduits116,118at selected axial positions. At step356, end fitting adapters120,124′ may be secured to one or both ends of the core wire120,120′. The second fitting portion206,206′ of the end fitting adapter124,124′ can be manipulated in manner that compresses the end fitting adapter124,124′ onto the core wire120,120′ so that the core wire120,120′ may remain relatively securely coupled to the end fitting adapter124,124′, such as, for example, lockingly secured to the end fitting adapter124,124′ when the core wire120,120″ is subjected to forces of up to around 100 pounds-force (lbf).

At step358, the excess core wire120,120′ may be trimmed or cut to a selected length, which can be based on a number of criteria, including, for example, the size of the entryway device106, the distance between the exit device100and the latch assembly(ies)104a,104b, and/or the type of latch assembly104a,104b, among other considerations. Further, as previously discussed, the selected location for trimming the core wire120,120′ may be attained, at least in part, through the use of a template spacer and may consider the location of a bead234of the core wire120′ received in an end fitting adapter124′, as previously discussed. According to some embodiments, the template spacer may be utilized to determine at least a portion, if not all, of the core wire extension length, as indicated by L1inFIG. 2.

While some embodiments are discussed herein in terms of exit devices, latches, and/or entryway devices, embodiments of the cable systems of the present application are applicable to a variety of other applications, including, but not limited to, automotive and aeronautical fields, among other fields. Moreover, the cable systems102a,102b,102′ discussed herein may be used in a variety of different types of applications and/or fields in which a push or pulling force is to be transmitted from one or more first devices, such as an activator device, to one or more second devices, such as, for example, an activated device, that is displaced in some manner by the force transmitted by the cable system102a,102b,102′. Further, the first activation device, as well as the second activated device, both of which can be directly or indirectly coupled to the cable system, can be configured to be displaced in a variety of different manners, including, for example, linearly, rotatably, pivotally, or a combination therefor. For example, according to some embodiments, rotatable displacement of a first activation device can be used to transmit a force through the cable system that linearly displaces the second activated device, or vice versa.

FIGS. 13A-13Dillustrate portions of an exemplary process for installing an exemplary cable system600that comprises selectively adjustable conduits116,118and a core wire120that can include at least one selectively adjustable end fitting608,614. The illustrated embodiment can improve the ease with which such cable systems600can be installed, and can reduce the number of potential issues associated with installation of cable systems that may contribute to installation failures including, for example, failures attributed to improper sizing in the length of the core wire120and/or the associated conduit(s)116,118. Moreover, the disclosed process and associated system can eliminate at least some measurements and associated calculations relating to determining a generally correct or operable length for the core wire120and/or conduit(s)116,118. Further, while the above embodiments reference a core wire120, embodiments disclosed herein are also applicable to other types of cables and/or rods.

According to some embodiments, installation of the cable system600can include providing the cable system600as part of a kit. The kit can include a cable system, which may be pre-assembled, and a position marker, among other potential items or components associated with the kit. Further, according to some embodiments, the kit can include hardware, including tools, that can be utilized in installing the cable system600and/or adjusting the lengths of components of the cable system600, including for adjusting or securing the overall length of a conduit that can comprise telescopically arranged conduits116,118, the position of end fittings608,614along the core wire120, and/or the length of the core wire120. Further, according to some embodiments, the cable system600may be preassembled in a manner in which the conduits116,118are adjustably engaged with one another, one or more of the end fittings are selectively adjustable relative to the core wire120, and/or the core wire120extends through at least a portion of the conduits116,118and/or end fittings608,614.

According to some embodiments, the position indicator602can be configured to provide at least a general indication of the location of a centerline604for the exit device100which, according to some embodiments or installations, can be the location or height relative to the floor, and can be based on a code regulation and/or application. According to installations that include at least a cable system600that extends toward the top edge108aof the entryway device106, the position indicator602can be aligned with the centerline604and extend toward the top edge108aof the entryway device106. Additionally, according to installations that include at least a cable system600that extends toward the lower edge108bof the entryway device106, the position indicator602can be aligned with the lower edge108bof the entryway device106and extend toward the top edge108aof the entryway device108aand/or toward the centerline604.

According to other embodiments, the position indicator602can include first indicia606, such as, for example, text, images, color, among other indicia, as well as a combination thereof, that provide an indication of the location of the centerline604. For example, as illustrated inFIG. 13A, the position indicator602can extend from around at least one of the top edge108aand the bottom edge108bof the entryway device106, and terminate generally at the location of the centerline604. Further, the first indicia606can include text, arrows, or other indicia indicating that a location along the position indicator602, or at an edge of the position indicator602, corresponds to the centerline604.

Additionally, the position indicator602can also include second indicia610, such as, for example, text, images, among other indicia, as well as a combination thereof, that provides an indication of the installation location at which a second end fitting608, an end of a conduit116,118, and/or a location of termination of the core wire120, among other possible components of the cable system600, are to be positioned, as discussed below in further detail.

The position indicator602can take a variety of different forms and configurations. For example, according to some embodiments, the position indicator602is a substrate having the first and/or second indicia606,610printed, etched, or otherwise indicated at least on one side of the position indicator602. Further, the position indicator602can be configured for at least temporary, selective vertical attachment to the entryway device106. For example, according to some embodiments, an adhesive material may be positioned on, or at least exposable from, at least a portion of a side of the position indicator602that can abut the entryway device106while still providing visual access to the first and/or second indicia606,610. However, the position indicator602can also be secured to the entryway device106in a variety of other manners and configurations including, for example, via one or more magnets that are attached to, or separately positioned against, the position indicator602, or providing the position indicator602with a static charge that at least can assist in securing the position indicator602to the entryway device106. Alternatively, according to other embodiments, the position indicator602may be vertically held by the installer(s) or otherwise lie against, or otherwise be coupled to, the entryway device106.

ReferencingFIG. 13B, according to some embodiments, the kit or installation process can also include the use of a fitting spacer612. The fitting spacer612can provide an indication of the installation location for a first end fitting614of the cable system600, the first end fitting614being installed at an end of the core wire120that is positioned proximally adjacent to a top or bottom edge108a,108bof the entryway device106, and/or which is located at a first end616aof the cable system600. According to the depicted embodiment, the first end fitting614can be similar to the adjustable end fitting500discussed above and shown in at leastFIGS. 10A and 10B. However, a variety of other types or configurations of end fittings can also be used for the first end fitting614.

In the illustrated embodiment, the fitting spacer612can engage the entryway device106, such as, for example, an edge or surface about or generally around the corresponding top or bottom edge108a,108bof the entryway device106, in a manner that at least temporarily secures a position of the fitting spacer612relative to the entryway device106. For example, according to the embodiment depicted inFIGS. 13B and 13D, the fitting spacer612can include a hook618that extends from a body portion622of the fitting spacer612, and which is sized to engage or otherwise hook onto a surface or edge of the entryway device106.

The body portion622also includes an engagement section624sized to engage the first end fitting614at a position that can correspond to a position at which, when installed, the connector620of the adjacent end fitting614can operably mate, engage, or otherwise be coupled to a mating latch assembly104a,104bor a latch bolt112. The body portion622can also include one or more cavities626that are sized to receive placement of other portions of the end fitting614and/or a conduit adapter190in a manner that operably separates the conduit adapter190from the end fitting614, and at a distance that may at least assist in operably positioning the first end fitting614about the core wire120at a location that facilitates proper operation of the exit device100.

According to the illustrated embodiment, with the position indicator602operably positioned on the entryway device106at a location that generally indicates the centerline604of the entryway device106, and the first end fitting614properly engaged with the engagement section624of a fitting spacer612that is secured to the entryway device106, such as, for example, via the hook618, the second indicia610on the position indicator602can be used to indicate where the second end fitting608or other portion of the cable system600that is or will be positioned proximally adjacent to the second end fitting608is to be positioned, as indicated, for example, inFIG. 13C. For example, referencingFIG. 13B, the second indicia610can be a line, color, text, or other indicia that provides an indication of where a particular surface or component of the cable system600is to be located, such as, for example, the location at which an wall of the conduit adapter190at a second end616bof the cable system600and/or an end of a conduit116,118is to be located. Such positioning of the cable system600relative to the location indicated by the second indicia610can, according to some embodiments, include adjusting a length of the telescoping conduits116,118and/or the relative locations of at least one of the first and second end fittings614,608relative to the core wire120and/or the conduits116,118. Further, such maneuvering or adjustment of the cable system600, or components thereof, can include pulling the cable system600relatively taut so as to attain relatively accurate positioning of the components.

According to the illustrated embodiment, the second end fitting608can correspond, for example, to the end fitting depicted inFIGS. 2A, 2C and 7, among other end fittings. Alternatively, according to some embodiments, the second end fitting608can correspond to the end fitting500, as depicted and discussed in connection withFIGS. 10A and 10B. Alternatively, the first end fitting614can have similar or different configuration as the second end fitting608.

With the first end fitting614of the cable system600operably secured in the fitting spacer612that extends from the top or bottom edge108a,108bof the entryway device106and the second end616bof the cable system600, such as, for example, the conduit adapter190, at a second end616bof the cable system600, generally positioned or aligned at a location indicated by the second indicia610of the position indicator602, the relative positions of the conduits116,118can be secured via operation of a conduit locking device611, such as, for example, the previously discussed conduit locking devices122,122′,400illustrated inFIGS. 4-6. With respect to at least the conduit locking devices122,122′,400depicted inFIGS. 4, 5A and 5B, the operation can at least initially involve hand tightening of the conduit locking device611before final tightening is performed through the use of a tool, such as, for example, a wrench or pliers, among other tools, which may be included with the kit.

With at least the relative positions of the conduits116,118secured, such installation can further include exerting a pulling force against the core wire120so as to remove excess core wire120between at least the first and second end fittings614,608, including between the connector620of the end fitting614and the second end fitting608, among other locations at which excess core wire120may be present. Further, such removal of slack or excess core wire120may at least attempt to allow for adjustment, if necessary, in the linear position of at least one of the first and second end fittings614,608, among other components of the cable system600. According to embodiments in which the first or second end fitting614,608has a configuration similar to the end fitting500previously discussed in relation toFIGS. 10A and 10B, such tightening of the core wire120can include pulling excess core wire120at least through the orifice526in the connector620of the corresponding end fitting614,608, and subsequently at least hand tightening the end fitting614,608so as to at least secure the position of the end fitting614,608relative to the core wire120. The fitting spacer612can subsequently be removed, and the end fitting614,608can be further tightened to the core wire120via use of a tool, such as, for example, a wrench that may or may not be part of the kit. Further, excess core wire120that extends away from the cable system600, if any, such as, for example, the core wire120extending from the orifice526of an end fitting608,614that has a configuration similar to the end fitting500discussed above in connection withFIGS. 5A and 5B, can be cut away from the other core wire120. Such cutting of excess core wire120may also occur at a location along the core wire120such that the resulting remaining end of the core wire120is generally flush with the adjacent end fitting614,608.

The above-discussed process is discussed in terms of a cable system600that extends between the centerline604to a latch bolt112or latch assembly104a,104bat one of the top and bottom edge108a,108bof the entryway device106. The process can also be repeated for another cable system600that extends between the centerline604and a latch bolt112or a latch assembly104a,104bat the other of the top and bottom edge108a,108bof the entryway device106. Further, removal of the cable system600, or further adjustments as to the relative positions of the conduits116,118or location of at least one of the first and second end fittings614,608along the core wire120, can generally be attained by loosening the associated conduit locking device611and/or end fitting614,608in manners similar to those previously discussed.

FIGS. 14A-14Cillustrate an incremental adjuster700that maintains the relationship between a conduit702a,702band a core wire704a,704bthat extends within the conduit702a,702bof one or more cable systems706a,706b. As previously discussed, while reference is made herein to a core wire704a,704bfor at least purposes of illustration, core wire704a,704bcan also include cable, rope, or wire rope, including, but not limited to, organic or synthetic semi-flexible braided material.

According to some embodiments, the incremental adjuster700provides adjustment in the relative positions of at least two cable systems706a,706bso as to accommodate changes in relative positions of the one or more systems the core wire(s)704a,704bis/are interfacing. For example, in order to often maintain the same functional relationship, whenever two systems of an exit device100including, for example, but not limited to, latch assemblies, among other types of components or assemblies, of exit devices, move closer or farther to/from each other, a size, such as length, of the core wire(s)704a,704bmay need adjustment, such as lengthened or shortened, in a manner that is generally proportional to the change in distance between the systems. In some embodiments, such changes in the distance between systems can be accommodated, to an extent, through the use of conduits702a,702bthat are rigidly fixed to each system, and moreover by the conduit(s)702a,702bbowing outwardly or coiling up so that the conduit702a,702band core wire704a,704bthat moves therein can have a degree of range. However, the degree to which conduits702a,702bcan bow or coil can be limited, for example, to the available space for such movement of the conduits702a,702b. Further, such bowing or coiling can result in an increase in friction in the operation of the cable system706a,706bthat can decrease the mechanical efficiency of the cable system706a,706b.

The incremental adjuster700can accommodate changes in the position in such systems by accommodating adjustments, in discrete amounts, of at least the relative linear positions of one or more cable systems706a,706b, and moreover can accommodate linear adjustments in generally the same amount or degree in both the conduit702a,702band the associated core wire704a,704bof the cable systems706a,706b. ReferencingFIG. 14A, according to the illustrated embodiment, the incremental adjuster700can include a conduit ladder708, cable ladder710, and one or more conduit clips712. Further, according to some embodiments, the incremental adjuster700can also include one or more cable clips714. Further, according to some embodiments, a conduit clip712and a cable clip714can be provided for a conduit702a,702band a core wire704a,704bof each cable system706a,706bthat is coupled to the incremental adjuster700.

The conduit clip712is configured to securely or lockingly engage at least a portion of the conduit702a,702bor a fitting716a,716b(FIG. 14C) connected to the conduit702a,702b, and to selectively and securely engage the conduit ladder708. The conduit clip712can have a variety of shapes and sizes. According to some embodiments, the conduit clip712can include a body portion718through which an orifice720extends, with the orifice720being sized to receive passage of at least a portion of a conduit702a,702band/or a portion of an fitting716a,716bthat is coupled to the conduit702a,702b, such as, for example, a conduit adapter190, as shown inFIG. 14C. Further, according to some embodiments, a size of the orifice720, such as, for example, a diameter, may be at least temporarily adjustable, such as, for example, via deformation, bending, pivoting, or deflection of at least a portion of the body portion718so as to accommodate the passage of the end fitting716a,716b, or another portion of the conduit702a,702b, through the orifice720. For example, according to some embodiments, a slot or opening722may extend from the orifice720to an edge724of the body portion718that can accommodate at least temporary expansion of the orifice720so that a fitting716a,716bcan pass therethough and/or be at least partially positioned in the orifice720in a manner that secures the conduit clip712to the fitting716a,716b, and thus to the conduit702a,702b. According to some embodiments, the fitting716a,716bcan include projections that can be inwardly bent or deformed to accommodate passage of at least a portion of the fitting716a,716binto and through the orifice720in a first direction, but which provide at least a degree of resistance to the return passage of the fitting716a,716bback through the orifice720in a second direction, the second direction generally being a direction that is opposite the first direction. Further, according to some embodiments, the orifice720and/or fitting716a,716bcan be configured to accommodate a snap, interference, or press fit therebetween. Alternatively, or optionally, the fitting716a,716band/or conduit clip712can be configured to be coupled together via use of a mechanical fastener, such as, for example, a clamp, screw, or pin, among other types of fasteners.

The body portion718of the conduit clip712can also include one or more extensions726that extend from the body portion718and which are configured for selective and removable secure engagement with the conduit ladder708. According to some embodiments, at least one of the extensions726can be configured to be at least temporarily deflected, bent, pivoted, and/or otherwise deformed from a first position to a second position to accommodate disengagement of the conduit clip712from one or more openings728in the conduit ladder708. Further, at least the extensions726may be constructed from a material that provides a degree or elasticity or resiliency so that, following deflection, bending, pivoting, and/or deformation of the extensions726to the second position, the extensions726can generally return to, or around, the first position.

As shown in at leastFIG. 14A, according to the illustrated embodiment, a base portion of the extensions726is coupled to the body portion718, with a gap730extending between the other adjacent portions of the extensions726and the body portion718. The gap730can have a size, such as, for example, a width, that can accommodate displacement of at least a portion of the extensions726as at least a portion of the extensions726move between the first and second positions during selective engagement and disengagement of the conduit clip712to/from the conduit ladder708. Further, according to some embodiments, the gap730can be sized to receive at least a portion of a sidewall734a,734bof the cable ladder710, and to allow the body portion718of the conduit clip712to be positioned in an interior region732of the cable ladder710while also allowing the extensions726to extend around734a,734bthe cable ladder710so that the extensions726can matingly engage selected openings728in the conduit ladder708, as shown for example, inFIG. 14C.

According to the illustrated embodiment, the conduit ladder708is configured to be selectively coupled or otherwise attached to one or more conduit clips712a,712b(FIG. 14C), as well as house at least a portion of the cable ladder710. While the conduit ladder708is illustrated at least inFIGS. 14A and 14Cas having a generally rectangular shape, the conduit ladder708can have a variety of other shapes and configurations that can accommodate incremental adjustments in at least the linear position of one or more of the conduit clips712a,712b, and thus associated conduit(s)702a,702bthat are coupled to the conduit ladder708via the conduit clips712a,712b.

According to the illustrated embodiment, the conduit ladder708includes a first sidewall736aand a second sidewall736bthat extend in generally the same direction from an interconnecting base wall738. Further, the first and second sidewalls736a,736band the base wall738can generally define an inner region740of the conduit ladder708that is sized to receive placement of at least a portion of the cable ladder710and the conduit clip(s)712a,712b. Further, as shown in at leastFIG. 14A, according to some embodiments, opposite first and second ends742a,742bof the conduit ladder708can be generally open in that sidewalls need not extend between the first and second sidewalls736a,736b, which may in turn improve the ease with which cable ladder710and the conduit clip(s)712a,712bmay be positioned or adjusted therein, as well as the ease of removal of at least those components from the incremental adjuster700.

According to the illustrated embodiment, the first and second sidewalls736a,736bof the conduit ladder708can have a plurality of openings728that are sized to receive selective insertion of at least a portion of the extensions726of the conduit clip712, such as, for example, insertion of a tab744that extends from an outer edge of the extensions726, as shown inFIG. 14A. The openings728can be arranged in pairs such that an opening728that is generally at a position along one of the first and second sidewalls736a,736bis at a location that that generally corresponds to the location of another opening728in the other of the first or second sidewall736a,736b. Additionally, according to some embodiments, the number of openings728at one end742aof the sidewalls736a,736bmay be different than the number of openings728generally at or around the other end742bof the first and second sidewalls736a,736b. Such a configuration may allow a first conduit clip712a(FIG. 14C) that is attached to one cable system706ato remain at relatively the same location relative to at least conduit ladder708during at least relative adjustment of the cable systems706a,706b. In such an embodiment, adjustments in the relative positions of at least the conduits702a,702bof the cable systems706a,706bcan at least be made by adjusting the openings728in which the other one of the conduit clips712bis engaged. Alternatively, according to other embodiments, rather than having a first removable conduit clip712athat remains at a relative static position relative to the conduit ladder708, the conduit ladder708can be formed, such as molded, to include a generally integral or fixed-position conduit clip712afor attachment of one of the cable systems706a,706b.

The cable clip714is configured to securely or lockingly engage the core wire704a,704bof a cable system706a,706b, and to selectively engage the cable ladder710at a selected position. The cable clip714includes a body portion746having an orifice748that is sized to receive insertion of a core wire704a,704b. The cable clip714can be configured to selectively lockingly engage or clamp onto the core wire704a,704bin a variety of manners so as to retain at least a linear position of the cable clip714relative to the core wire704a,704b. For example, according to some embodiments, the cable clip714can include a hole749in communication with the orifice748and which can be threaded so as to receive a set screw or other mechanical fastener that can be tightened against at least a portion of the core wire704a,704bthat is positioned in the orifice748. According to such an embodiment, adjustment of at least the relative positions of the set screw and core wire704a,704bcan be attained by loosening the set screw (if tightened), adjusting at least the relative linear positions of the core wire704a,704band the cable clip714, and tightening (or re-tightening) the set screw. However, as discussed above, other manners of retaining the relative linear positions of the cable clip714and core wire704a,704bcan also be employed.

The cable clip714can also include a pair of arms750that extend from opposite sides of the body portion746of the cable clip714. Each of the arms750can have similar or dissimilar shapes, sizes, and/or configurations. Further, the arms750can be configured to mate with openings756, such as holes, slots, and/or grooves, in opposite sides of the cable ladder710, as discussed below. According to the illustrated embodiment, the arms750can have generally cylindrical configurations. Further, according to some embodiments, the arms750can have generally circular cross sectional shapes that can accommodate rotational displacement of the cable clip714when the arms750are securely engaged with the cable ladder710.

The cable ladder710is sized to be at least partially positioned within the inner region740of the conduit ladder708and to matingly engage the arms750of the cable clip(s)714a,714b. According to the illustrated embodiment, the cable ladder710includes a first sidewall734aand a second sidewall734bthat extend in generally the same direction from an interconnecting base wall752. Further, the first and second sidewalls734a,734band the base wall752of the cable ladder710can generally define an interior region732of the cable ladder710that is sized to receive placement of the cable clip(s)714a,714band possibly at least a portion of the fitting716a,716bof the conduits702a,702b. Further, as shown in at leastFIG. 14A, according to some embodiments, opposite first and second ends754a,754bof the cable ladder710can be generally open in that sidewalls need not extend between the first and second sidewalls734a,734b, which may in turn improve the ease with which at least a portion of the fitting716a,716bof the conduits702a,702band/or the cable clip(s)714a,714bmay be positioned or adjusted therein, as well as the ease of removal of at least those components of the incremental adjuster700.

According to the illustrated embodiment, the first and second sidewalls734a,734bof the cable ladder710can have a plurality of openings756that are sized to selectively receive insertion of at least a portion of the arms750of the cable clip(s)714a,714b. The openings756can be arranged in pairs such that an opening756that is generally at a position along one of the first and second sidewalls734a,734bgenerally corresponds to the location of another opening756in the other of the first or second sidewall734a,734b. Further, the openings756in the first and second sidewalls734a,734bcan have similar or different shapes and/or sizes. For example, according to some embodiments, the openings756in the first sidewall734acan be generally circular shaped holes that may break through an upper edge758aof the first sidewall734a, while the openings756along the second sidewall734bcan be grooves, slots, or elongated openings that extend or break through an upper edge758bof the second sidewall734b. Further, the openings756of the second sidewall734bcan be elongated in an angled direction that is not perpendicular to the surface of the upper edge758bof the second sidewall734band/or is not perpendicular to the base wall752. The openings756of the first and second sidewalls734a,734bcan, however, have a variety of other shapes and configurations, as well as combinations thereof.

Additionally, similar to the conduit ladder708, according to some embodiments, the number and/or the shape of the openings756at one end754aof the sidewalls734a,734bof the cable ladder710may be different than the number, size and/or shape of the openings756generally at or around the other end754bof the first and second sidewalls734a,734bof the cable ladder710. As shown inFIG. 14C, such a configuration may allow a first cable clip714a(FIG. 14C) that is attached to a cable system706aand which is operably engaged with the first conduit clip712ato remain at relatively the same location relative to at least the cable ladder710and/or the conduit ladder708. In such an embodiment, adjustments in the relative positions of at least the core wires704a,704bof the cable systems706a,706b, and/or relative adjustments between the cable systems706a,706b, can at least be made at least in part by adjusting the openings756in the cable ladder710in which the other one of the cable clips714is engaged, such as, for example, by adjusting the openings756that a second cable clip714b(FIG. 14C) engages in the cable ladder710. Further, according to such an embodiment, rather than having a first removable cable clip714athat remains at a relative static position relative to the cable ladder710, the cable ladder710can be formed or molded to include a generally integral or fixed-position cable clip714a.

During use, a first conduit clip712acan be engaged with a fitting716aor other portion of a conduit702aof a first cable system706aand secured in a single pair of openings728at a first end742aof the conduit ladder708. Further, the core wire704aof the first cable system706acan be securely engaged with a first cable clip714aand be inserted into a single pair of openings756that are located at a first end754aof the cable ladder710. A second cable clip714bcan also be secured to the core wire704bof a second cable system706band selectively positioned to securely engage a pair of opposite openings756of the cable ladder710. The second conduit clip712bcan also be engaged with the fitting716bor other portion of the conduit702bof the second cable system706b. The second conduit clip712bcan be selectively secured to the conduit ladder708via engagement of the extensions(s) with openings728in the conduit ladder708. Further, the openings728of the conduit ladder708selected for engagement may be those openings728that cause at least the conduits702a,702bof the first and second cable systems706a,706bto be relatively taut, and moreover, that reduce or eliminate excessive and/or unnecessary slack in the cable systems706a,706b.

According to some embodiments, each pair of openings756of the cable ladder710and each pair of openings728in the conduit ladder708can correspond to a particular position of at least one cable system706brelative to the incremental adjuster700. For example, the third pair of openings756from an end754bof the cable ladder710and a third pair of openings728from an end742bof the conduit ladder708can correspond to a third position of the associated cable system706brelative to the incremental adjuster700. Thus, according to some embodiments, the pair openings756in which the second cable clip714bis selected for securing to the cable ladder710may correspond to the pair of openings728in the conduit ladder708to which the associated conduit clip712bis, or is to be, secured.

With the conduits702a,702bof the cable systems706a,706beach secured to the conduit ladder708, the conduits702a,702b, and conduit ladder708can function as a first semi-rigid unit with constant length, making the conduits702a,702bact as a common ground. Similarly, with the core wires704a,704bof the cable systems706a,706beach secured to the cable ladder710, the core wires704a,704band cable ladder710can function as a second semi-rigid unit having a constant length, and making core wires704a,704bact as a single core wire. Accordingly, when an input force causes one of the core wires704ato be actuated, the associated force can be transmitted through the core wires704a,704band cable ladder710as if the core wires704a,704band cable ladder710were a single, nonadjustable core wire.

Furthermore it should be understood that while the use of the word preferable, preferably, or preferred in the description above indicates that feature so described may be more desirable, it nonetheless may not be necessary and any embodiment lacking the same may be contemplated as within the scope of the invention, that scope being defined by the claims that follow. In reading the claims it is intended that when words such as “a,” “an,” “at least one” and “at least a portion” are used, there is no intention to limit the claim to only one item unless specifically stated to the contrary in the claim. Further, when the language “at least a portion” and/or “a portion” is used the item may include a portion and/or the entire item unless specifically stated to the contrary.
