Title: Adjustable power and data rail for desks

Description:
BACKGROUND 
     Vertically adjustable desks are often grouped together in multiple working group configurations. This includes a number of desks which have a work surface which is supported by a first and a second leg, both the first and the second leg of the desk are vertically adjustable to change the elevation of the work surface. Such adjustable desks are becoming more popular due to the flexible height of the work surface and the ability of the user to sit at the desk work surface or stand at the work surface of the desk. Further, while it is common to join multiple desks into connected work surfaces, providing power and data to these various installation configurations can prove difficult. Not only are the vertically adjustable desks provided in varying lengths, but due to the ability to raise the desks, the height necessary for data and power ports is modified depending on a particular configuration. 
     SUMMARY 
     The present disclosure includes adjustable power and data rails for static height and vertically adjustable desks. The adjustable rails can be combined into connected adjustable power and data rails to interconnect between multiple combined vertically adjustable or static height desks. For example, a first and a second adjustable power and data rail may be combined beneath a plurality of, for example, four vertically adjustable desks wherein the power and data rails are connected below and between the vertically adjustable desk work surfaces. In implementations the adjustable power and data rails are adjustable in both the vertical and horizontal directions in order to match the height and length requirements of the joined vertically adjustable desks. 
     For example, the adjustable power and data rails may be adjustable horizontally with respect to the static height or vertically adjustable desks to adjust for varying length requirements of the desk installation. In some implementations, the adjustable power and data rails may be horizontally adjustable by utilizing telescoping rail extensions which are received into a central rail assembly. The overall horizontal length of the power and data rail may thus be adjusted by inserting the rail extensions at either a first and/or a second end of the central rail assembly. Each of the rail extensions may be locked into their positions, when either one or both are utilized on either side of the central rail assembly, by a securing mechanism. For example, at least one set screw may be utilized to secure the horizontal position of the rail extension with respect to the central rail assembly. In various implementations, the securing mechanism may fit into a rail adjustment slot of the central rail assembly securing the central rail assembly and the rail extension into place relative to each other. 
     The adjustable power and data rails may also be vertically adjustable with respect to the vertically adjustable desks to adjust for varying height requirements of the vertically adjustable desk installation. In some implementations, the adjustable power and data rails may be vertically adjustable by utilizing a rail post having a telescoping upper and lower rail post sections. The upper rail post may receive the related rail extension to form the power and data rail under the entirety or a portion of the vertically adjustable desk assembly. The overall vertical height of the power and data rail may thus by modified by adjusting and securing with respect to each other the upper and lower rail post. The upper or lower rail post may be secured with a securing mechanism which may extend through an outer of the upper or lower rail post to secure the outer post relative to the inner post. Either the upper rail post or the lower rail post may be utilized as the inner post or the outer post. 
     For example, the lower rail post may telescopically fit into the interior of the upper rail post and slide vertically relative thereto. In some examples, the lower rail post may be secured in position with respect to the upper rail post by use of securing mechanisms. For example a first and a second set screw may extend through the outer, upper rail post, to secure the position of the upper rail post with respect to the inner, lower rail post such that the lower rail post slides vertically into the upper rail post. 
     In some examples, the adjustable power and data rails include a first and a second end rail post with a single or multiple interposed central rail posts. Each of the first and the second end rail posts may be vertically adjustable. A central rail post may receive the power and data rails from respective first and second end rail posts, the central rail post also being vertically adjustable in similar fashion as compared to the first and second end rail post. 
     Power and data lines may be fitted and extend along at least a portion of the length of the data rails including the rail extensions and the rail assembly which receives the rail extensions. In other implementations, the rail extensions may receive the central rail assembly and either construction is included in the teachings hereof. Further a wire tray may be fitted along at least a portion of the length of the central rail assembly. 
     In implementations, the central rail posts and the first and the second end rail posts may each be vertically adjustable. Also, the rail assembly may be horizontally adjustable in combination with the adjustable end and central rail posts. 
     In implementations, the adjustable power and data rail may be positioned below and along the length of a plurality of vertically adjustable desks. For example, the adjustable power and data rail may be positioned below a quadrant of vertically adjustable desks. In other implementations, the adjustable power and data rail may be positioned below a triad of vertically adjustable desks wherein the adjustable power and data rails include a central rail post and a first, second and third end rail post. In implementations, the adjustable power and data rail, regardless of the number of vertically adjustable desks, can be both vertically and horizontally adjustable to match the required vertical desk installation. 
     In further examples, the adjustable power and data rail may include at the first and second end rail post a foot bracket which has a first and a second aperture for receiving the respective foot pad from opposing static height or vertically adjustable desk foot. In some implementations, the adjustable power and data rail may include at the center rail posts a central foot bracket which has a first, second, third and fourth aperture for receiving the respective foot pad from opposing desks. For example, in some implementations, the foot bracket has multiple apertures to receive a foot leveling pad from one desk and at least another foot pad from a facing desk to secure the desks in position relative to the adjustable power and data rail and relative to each other. 
     In additional implementations, the adjustable power and data rail may include a center rail post which includes a central foot bracket for affixation to adjacent and/or facing respective static height or vertically adjustable desk foot. For example, in some implementations, a central rail post central foot bracket may include a first, second, third and fourth attachment point or flanges which affixes above, underneath or adjacent to respective first, second, third and fourth desk foot. 
     Further, in implementations, extending between the first and the second end rail posts may extend the power and data lines either interiorly or exteriorly of the horizontally adjustable rail assembly and rail extensions. 
     In various implementations, the adjustable power and data rail may be combined with a plurality of vertically adjustable desks wherein the desks include a horizontal work surface and a first and a second vertically adjustable or static leg. Each of the first and the second leg may include a desk foot, the desk foot for the desk having a first and a second desk foot pad. In examples, a foot pad of respective facing desks may be positioned within a respective aperture of the foot bracket for the adjustable power and data rail posts to secure the respective facing desks relative to the power and data rail. 
     Each of the vertically adjustable desk may also have an electric motor to adjust the vertical position/height of the horizontal work surface. The electric motor may be operable by power controls for the vertically adjustable desk allowing the height of the first and the second vertically adjustable legs of the desk to be adjusted without necessitating adjustment of the power and data rails extending below the vertically adjustable desks. 
     Various implementations of an adjustable power and data rail for use with vertically adjustable desks are disclosed herein.

     DETAILED DESCRIPTION 
     Various implementations are disclosed herein for an adjustable power and data rail which can be used for static height and vertically adjustable desks. In various implementations, the adjustable power and data rail may be adjustable in both the vertical and horizontal directions thereby accommodating differing length vertically adjustable desk installations. 
     As depicted in  FIG. 1 , a grouping of vertically adjustable desks  100  are provided having an adjustable power and data rail  50  interposed between groups of paired facing desks  100 . The adjustable power and data rail  50  is positioned to feed both power and data connectivity to each of the vertically adjustable desks within the group. Further, depending on the particular style or installation of vertically adjustable desks  100 , the adjustable power and data rail  50  may be accommodated by modifying the length and/or height of the rail  50 . 
     Referring to  FIGS. 1 and 2 , a grouping of vertically adjustable desks  100  are in paired face to face relationship. The power and data rail  50  is positioned in between pairs of desks and is adjustable horizontally, depending on the width of the desks  100 , or vertically as may be dictated by connectivity concerns or height requirements for the desks. Each of the desks are vertically adjustable by a control  108  which raises and lowers the working surface  101  by virtue of the adjustable legs  110  which are expanded or retracted by at least one electric motor positioned within the vertically adjustable legs. 
     Each of the vertically adjustable desks  100  includes legs  110  which have a desk foot  104  and desk foot pad  105 . Each of the desks within the combined configuration may be independently adjusted vertically within the grouping while the power and data rail  50  interconnects the group of desks together by use of the end post rail foot bracket  34  and center rail post central foot bracket  43 ,  49  or  49   c . As a result, the electrical and data connectivity of the desks  100  to the adjustable power and data rail  50  can be maintained and secured. 
     In  FIGS. 3 and 4 , the adjustable power and data rail includes two end rail posts  31   a  and a center rail post  31   b . Positioned between the center rail post  31   b  and each of the end rail posts  31   a  is a rail assembly  38  and a first and a second rail extension  36 . The rail extensions  36  positioned at either end of the rail assembly provide the ability to adjust each left and right portion of the adjustable power and data rail horizontally to fit various width vertically adjustable desk configurations. For example, each rail extension  36  may fit or telescope into an interior portion of the rail assembly  38  and be adjustable along the length of the rail extension  36 . In some instances, the individual rail extensions may telescope into the rail assembly and be secured in position to allow for extended length. In still further instances, the rail assembly may fit or telescope into the rail extension allowing for horizontal adjustment of the length of the adjustable power and data rail system  50 . 
     The horizontal length of the power and data rail  50  may be adjusted based upon the length of each of the rail extensions  36 . For example, in the embodiment depicted in  FIGS. 3 and 4 , the power and data rail  50  may be horizontally adjusted up to four times the length of each of the rail extensions  36 . Various implementations may include each of the four individual rail extensions  36  depicted. Other embodiments may include fewer rail extensions. For example, in some implementations, a single longer rail extension may be provided at one end of the rail assembly wherein the opposite end of the rail assembly directly or indirectly attaches to the end rail post  31   a  or center rail post  31   b . Various implementations may incorporate modifications to the rail extensions  36  to allow for increased expandability. For example, in some implementations, a single longer rail extension  36  may be provided on one end of the rail assembly  38 . In other implementations, various combinations of single, double or no rail extensions may be provided. 
     Each of the rail extension  36  depicted in the figures slidingly engages the adjacent rail assembly  38  to allow for horizontal or width adjustability. As depicted in these figures as well as  FIGS. 6 and 7 , the rail extension may slide relative to the rail assembly  38 . For example, the rail extension as shown may telescope internally to the rail assembly. Other configurations may be implemented such as, for example, the rail assembly sliding into the interior of the rail extension, bolt on extender blocks between the rail extension and the rail assembly, or other structure allowing for adjustable horizontal expansion or decrease of the length of the power and data rail  50 . 
     In various implementations, securing mechanisms may be implemented to secure the relative position and horizontal adjustability of the rail extension to the rail assembly. For example, in some implementations, a rail assembly slot  37  may be provided to receive a locking screw/securing mechanism  47 . The locking screw  47 , extending through the slot  37 , may secure the relative position of the two structures once the overall length and position is decided. Other configurations of a securing mechanism may be implemented. For example, instead of a slot, a plurality of apertures may be provided for a securing device to extend through the rail assembly to the rail extension. As well, many types of securing devices may be implemented as a securing mechanism/locking screw. For example, cam levers, compression nuts or other structure may fixate the rail extension position relative to the rail assembly position. Also, for example, similar devices may be provided to fixate the rail assembly position relative to the rail extension position if alternative adjustable movement is implemented. For example, if the rail assembly telescopes into the rail extension, alternative securing mechanism are supported for fixating relative positions. 
     Similarly, vertical adjustment may be implemented at each of the center rail post  31   b  and the end rail posts  31   a . Vertical or height adjustability may be provided at each of the posts. For example, an upper rail post  30  and lower rail post  32  combination allows relative movement between the upper and lower rail post  30 / 32  to adjust the overall vertical position of the rail assembly  38  for the adjustable power and data rail  50 . In implementations, a lower rail post  32  may slide relative to the upper rail post  30  to adjust for varying height requirements. For example, the lower rail post may slide or telescope into upper rail post  30  and be secured relative thereto. As depicted in the figures and in combination with  FIG. 8  and the center rail posts  31   c  of  FIGS. 11-14 , the lower rail post  32  may fit into the upper rail post for the center rail post  31   b / 31   c . The position of the two structures of the lower and upper rail post  30 / 32  may be fixated by locking screws/securing mechanisms  47 . Lower rail post  32  may also have an adjustable foot pad  42  at a lower end therein that is vertically adjustable by threads or other securing mechanism. 
     In implementations, securing mechanism  47  for the center and end rail post  31   b / 31   a  may lock the relative positions of the two upper and lower rail post structures. For example, locking screws and adjustment slots may be configured. In other examples and configurations, a plurality of apertures may receive the mechanisms allowing a fastening structure to extend through an outer structure to affix or provide pressure to an inner structure. Other securing devices may be used in place or in addition thereto such as cam locks or similar devices described herein. Alternatively, in some implementations, the center and end rail posts can be fixed in height with adjustable foot pads which raise and lower the height of the power and data rail structure. In implementations, means are provided to adjust the vertical positioning of the power and data rail structure at each of the rail posts to equalize their height. 
     In such implementations, the vertical height of the power and data rail  50  may be adjusted at each of the rail posts  31   a ,  31   b ,  31   c . The variability of the vertical adjustment may be modified through the length of the upper and lower rail posts  30 ,  32  or with regards to additional structure interposed between the lower rail post  32  and the rail post foot bracket  34  as noted. 
     Rail post foot bracket  34  may attach to a lower end of the lower rail post  32  to increase the stability of the contact point of the rail post  31   a  and the ground. Securing or affixing the power and data rail  50  to the vertically adjustable desks  100  may also include foot bracket  34  provided with a first and a second aperture  41   a ,  41   b  at opposing ends of the foot bracket. Foot bracket apertures  41   a ,  41   b  as shown in  FIG. 5 , may interlock with the associated desk foot pad  105 . Providing apertures  41   a ,  41   b  in the bracket  34  allows the foot pads  105  from adjacent desks to be evenly positioned on the floor or supporting surface as the bracket  34  thereby positioning them at common horizontal height. Foot bracket apertures  41   a ,  41   b  allow for securing the adjustable power and data rail to the vertically adjustable desks. For example, forward facing vertically adjustable end legs may be interlocked in the bracket  34  as depicted in  FIGS. 1 and 2  securing the vertically adjustable desks to the power and data rail. 
     Securing or affixing the power and data rail  50  to the vertically adjustable desks  100  may also include the central foot bracket  43 . Central bracket can be considered a center rail post foot bracket for retaining desks in adjacent relationship. For example, central foot bracket  43  may include attachment flanges  43   a ,  43   b ,  43   c ,  43   d , at four points to attach to the underside of vertically adjustable desks foot  104  which are all co-adjacent in a quadrant. For example, a quadrant of four vertically adjustable desks, is formed by placing them in paired front facing relationship thereby positioning four adjacent desk foot  104 , as shown in  FIG. 2 , all of which may be attached to the central foot bracket  43  of the adjustable power and data rail  50 . Central foot bracket  43  may variously be affixed to the plurality of adjacent desk feet  104 . For example, the bracket may be placed on a lower surface, side surface or upper surface. Alternatively, bracket may provide sleeves for desk feet  104  to fit into or ay secure to a portion of the vertically adjustable leg  110  of the desk  100 . 
     Alternatively, as depicted in  FIGS. 11, 12, 13, 14  the central foot bracket  49 ,  49   c  may receive the associated desk foot pad within four receiving apertures of the central foot bracket  49 . In such manner, the central foot bracket allows the power and data rail  50  to securely be connected to the adjacent desks while also removing the requirement of direct attachment of the desk to the bracket. In such implementation, central post  31   c  may be fully adjustable for the modifiable height of the power and data rail similar to the end posts while also allowing the power and data rail to be secured to the desks by simply receiving the respective foot pad within bracket  49 . The central post  31   c  may be constructed of a two-piece post similar to the end posts wherein the two posts structures form an upper and lower post such as upper and lower post  30 ,  32  of the end rail post. Further, such central post  31   c  may be telescoping and adjustable to modify the height of the central post  31   c  similarly to the end posts  31   a . Further, in the variations shown in these figures, a central partition  70  may be provided between facing desks and supported by partition brackets  71 . As well, in variations, the data port and power port  33 ,  35  may be positioned respectively on the outward facing surface of the power and data rail or in multiple faces, such as for example mixing the positions of the power and data ports on a side surface, bottom surface or combination thereof. 
     As shown in the figures, rail assembly  38  in implementations may have a hollow interior allowing for wire ways for cable or other wiring to extend. Data ports  35  and electrical ports  33  may be provided at various locations of the rail assembly  38  allowing for connectivity of user vertically adjustable desk user devices. Associated wire trays  39  along a portion of the length of the rail assembly may be provided to retain length of cables connected to the data ports or the power ports  33 . Data ports  35  are depicted as being provided on an outer surface of the rail assembly  38  but may be placed at any position along the outward facing side or lower surface of the rail assembly, or combinations thereof, for accessibility. Similarly the power line ports  33  may be positioned along the rail assembly at desired locations to allow user devices to access power fed to the power line ports from standard line voltage power sources. 
     Various configurations of vertically adjustable desks may utilize the associated adjustable power and data rail  50 . For example, linear desk configurations, T-shaped, 4-way and 120-degree desk configurations may be integrated with the adjustable power and data rail system disclosed herein. For example, as depicted in  FIGS. 9 and 10 , vertically adjustable desk configuration  200  utilized 120-degree configuration of the adjustable power and data rail  260 . Rail  260  may include a 3-way central post  212  which connects to three different rail assemblies  210   a ,  210   b  and  210   c . Each of the rail assemblies may include a previously described rail assembly and rail extensions. For example, the rail assembly  210   a/b/c  may each include a single rail assembly with rail extensions on either ends of the rail assembly and may also include power and data rail foot bracket  34  at the respective end posts. 
     The 120-degree configuration  200 , as depicted, includes three vertically adjustable desks  202   a ,  202   b  and  202   c  and an adjustable power and data rail  260  interposed between facing desks. The data rail assemblies  210   a ,  210   b  and  210   c  carry data and power lines for connection by user devices. The power and data rail  260  is similarly adjustable in both the vertical and horizontal direction as noted herein using the various rail extensions and alternatives as well as the upper and lower rail posts and alternatives described. The center rail post  212  is connected to each of the respective three end posts while having a respective rail assembly extending between the central rail post and the end rail post, along with the rail extension as needed. Vertically adjustable desk attachment bracket  220  may affix adjacent vertically adjustable desk feet together to secure the various desks together. Attachment bracket  220  may be provided at the joinder point of any adjacent desk feet. 
     As depicted in the further variations of  FIGS. 13 and 14 , another embodiment of the 120-degree desk configuration  200  is depicted similarly positioned but with vertically adjustable central post  31   c  and receiving bracket  49   c . In such variation, while receiving bracket is positioned centrally to the three desks, it has a triangular configuration to increase stability of the power and data rail  50  since the rail branches between the three desks at 120 degrees. The central receiving bracket  49   c  does not receive an associated desk foot pad from an adjacent desk but is provided as a central stabilization point for the rail  50 . Brackets  220  may be provided to secure adjacent desks to one another. 
     While several inventive embodiments have been described and illustrated herein, those of ordinary skill in the art will readily envision a variety of other means and/or structures for performing the function and/or obtaining the results and/or one or more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the inventive embodiments described herein. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the inventive teachings is/are used. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific inventive embodiments described herein. It is, therefore, to be understood that the foregoing embodiments are presented by way of example only and that, within the scope of the appended claims and equivalents thereto, inventive embodiments may be practiced otherwise than as specifically described and claimed. Inventive embodiments of the present disclosure are directed to each individual feature, system, article, material, kit, and/or method described herein. In addition, any combination of two or more such features, systems, articles, materials, kits, and/or methods, if such features, systems, articles, materials, kits, and/or methods are not mutually inconsistent, is included within the inventive scope of the present disclosure. 
     All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms. 
     The indefinite articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.” 
     The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc. 
     As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e. “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law. 
     As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc. 
     It should also be understood that, unless clearly indicated to the contrary, in any methods claimed herein that include more than one step or act, the order of the steps or acts of the method is not necessarily limited to the order in which the steps or acts of the method are recited. 
     In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” “composed of,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of” and “consisting essentially of” shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures, Section 2111.03. It should be understood that certain expressions and reference signs used in the claims pursuant to Rule 6.2(b) of the Patent Cooperation Treaty (“PCT”) do not limit the scope.
