FIELD OF THE INVENTION
This invention relates to connectors or coupling devices and more particularly to coupling devices for attaching to an anchor member.
BACKGROUND AND SUMMARY OF THE INVENTION
This invention relates generally to coupling devices for attaching to an anchor member. Such a coupling may be equipped with any manner of elongated members such as for example and without limitation a tether, a leash a web, a wire, or a rope. So, for example, the coupling device may be releasably engaged or coupled at one end with an anchor member on a collar worn by an animal and engaged or coupled at the other end with a leash, the leash being tended by a human.
It is desirable to provide a coupling device configured to releasably engage an anchor member. Such a coupling device may be released even if release is being resisted, say for example and without limitation by an animal pulling at its leash as a user tries to disengage the coupling device at the end of the leash from the anchor member on the animal's collar. A coupling device is provided generally comprising a lever or locking member having a locking appendage or tooth located at the lever's distal end. The lever, which may or may not be monolithic, illustratively is movably mounted within a housing or cover. The cover may define a recognizable shape such as an animal, a human, an inanimate object, a fictitious being and the like. For example, the cover may resemble the head of a dog, any dog. No matter what the cover is shaped to resemble, it may have protrusions to aid in gripping and identification of the coupling device. For example, in the case of a dog head, the cover may have anatomically correct or representative protrusions such as ears, eyes, top of head or forehead and the like. These protrusions aid in gripping the coupling device while disengaging or engaging it with an anchor member. The cover also defines a mouth that resembles the mouth of the animal, and is configured to receive the anchor member. The coupling device could also be coupled with other objects, such as a set of keys. The cover could also be equipped with sound or illumination devices and may be colored. The cover's color may be any color or combination of colors. For example, the cover could have a fanciful color like blue, or it could be realistic such that a cover shaped like a Golden retriever head might have a black nose, brown eyes, and fawn or golden colored fur.
The lever may pivot about a mounting member relative to the cover in order to close or open the mouth. In the closed position, the tooth substantially covers the mouth and retains an anchor member therein. The lever may be biased into the closed position by a bias member, such as for example a spring. In the open position, the tooth is substantially withdrawn from the mouth such that it is substantially open or uncovered to allow the insertion or extraction of the anchor member from the mouth. The pivot point of the lever may be located near the proximate end of the lever, or it may be located between the lever's proximate and distal ends. The leading or engagement edge of the lever may be angled to allow it to be moved or pivoted about the mounting member by engaging another structure, such as a rigid anchor member, which causes the lever to move through camming. The lever also may be moved to the open position by direct manipulation of the lever. Having a generally S-Shaped lever that pivots near the proximate end of the lever allows the direct manipulation portion to be located between the lever's distal and proximate ends or even toward or at the proximate end if desired. With this arrangement, a user may grasp the gripping protrusions, such as ears, eyes, forehead, of the cover and apply pressure against the direct manipulation portion in order to overcome the bias force and move the lever into the open position. The lever may also be moved through internal forces, such as camming forces. In such a case a camming pin or member inside the cover might impinge upon a camming portion of the lever when a force is applied to a suitable structure to move the camming pin. Such a suitable structure might be a button.
The coupling device may further comprise a frame assembly sized to fit within the cover and sized to nestle and mount the lever. The coupling device may further comprise a mounting assembly including an anchorage. The anchorage may be configured to couple with any suitable elongate member. The elongate member may be any suitable flexible, semi-flexible, semi-rigid or rigid member, and may be for example a leash, a tether, a web, a rope, a wire, a tube and the like without limitation. The mounting assembly may be detachable from the coupling device. So, for example, the coupling device may remain coupled to the anchor member on a pet's collar while the mounting assembly may be detached along with a leash that is attached to the anchorage. The anchorage may move about a longitudinal axis through an anchorage mount carried on the mounting assembly. The elongate member may be permanently, semi-permanently or releasably coupled to the anchorage through any suitable structure or method, such as for example and without limitation, sewing, snapping, clipping, riveting, gluing, hook and looping, bracketing, sliding association, and the like or any combination of the foregoing.
Each of the cover, the frame assembly, the lever, and the mounting assembly may, but need not be of monolithic construction. So too, a cover and frame assembly combination may but need not be of monolithic construction; a frame and mounting assembly combination may but need not be of monolithic construction; a cover and mounting assembly combination may but need not be of monolithic construction; and a cover, frame assembly and mounting assembly combination may but need not be of monolithic construction. In the event that the above combinations are not monolithic, then they may be coupled together using any suitable fastener device or means, such as bolts, rivets, screws, glue, cement, weld, solder, and the like without limitation. So too, the cover may be snapped onto the frame and/or mounting assembly and vice versa. So too, a combination of monolithic construction and fastening devices or methods may be used. Each of the cover, the lever, the frame assembly, and the mounting assembly may be fashioned from any suitable metallic, non-metallic, or composite material or combination thereof by any method of manufacture suitable for the material or combination of materials used.

So too, the cover 11, 111 may be fashioned into any other type and species of animal, for example farm animals, wild animals, domesticated animals or fictional animals. The surfaces may resemble, for example, the mascots of sports teams, the characters of amusement parks or cartoons, the characters in fairy tales and the like. The surfaces may even resemble people, caricatures of people, super heroes, comic book characters, movie characters, cartoon characters and the like. The scope of the invention is meant to include any type of human, animal, terrestrial, fictional and/or inanimate shape, such as for example a boat, a car, a cycle, a building, and the like.
Surfaces 22, 24, 25, 28, 30, 122, 124, 125, 128 define a cavity 37 having an opening 38 through the end of the housing 11, 111 opposite from end surface 30. The other end of housing 11 defines an opening, notch, or mouth 36 having a seat 34 and configured to receive an anchor member such as for example a D-ring 16 (FIGS. 3A, 3B, 8A, 8B) or other suitable anchor member, coupling or connector. Illustratively, such a D-ring might be of the type found on an animal collar such as for example a dog or cat collar, or it might be a round bar found in the lower attachment of motor vehicles as mandated by Federal Motor Vehicle Safety Standards (“FMVSS”) such as standard 213 codified at 49 C.F.R. §571.213, which is incorporated herein by reference. Mouth 36 opens through end surface 30 and side surfaces 24, 25, 124, 125 and conceptually divides end surface 30 into an upper portion 32 and a lower portion 33. Cavity 37 is generally though not necessarily rectangular in cross section, generally extends from the opening 38 to the mouth 36, and generally is sized to snugly receive therein the other components 12, 13, 14, 69, 112, 113, and 114 of the connector 10, 110. Cover or housing 11 also has a coupling aperture 27 formed to receive any conventional connector or fastener, such as for example mounting member 60, to secure the cover or housing 11 to and/or with the other components when assembled. As one of any number of suitable alternatives to the use of fasteners, cover 111 snaps into place without the need for any type of fastener. More specifically, bottom surface 128 includes a generally arcuate portion and has formed therethrough a void or opening 29, which is in communication with cavity 37 and which is bounded at its proximate end by edge or lip 26 formed in the bottom surface 128. When the cover 111 is slid over frame assembly 113, or the frame assembly slid into cover 111, edge or lip 26 retains frame assembly 113 in place by abutting locking protrusion or appendage 62 of the frame assembly 113. It is also within the scope of the disclosure for the cover 10, 110 and the frame assembly 13, 113 to be of unitary or monolithic construction.
It will be appreciated that the cover or housing 11, 111 need not be of monolithic construction and that it may be made of any suitable non-metallic, metallic, or composite materials, or a combination thereof if desired. For example and without limitation, all or a portion of the cover or housing 11, 111 may be made of graphite, titanium, zinc, aluminum, kevlar, and the like. In addition, the cover or housing 11, 111 may be manufactured using any process compatible with the material being used, such as, for example, injection molding, die casting, stamping, or the like. Moreover, the cover or housing 11, 111 may be manufactured using different colors or combinations of colors such as for example black, blue, purple, yellow, red, white, orange, brown, green, gray and various other colors and shade thereof. The cover or housing 11, 111 may be luminescent such that it glows in the dark.
As best seen in FIG. 4, illustratively, the mounting assembly 12 of coupling device 10 generally comprises a frame 50 having a pair of spaced apart side walls or surfaces 54, 55 (FIG. 3A) and carrying an anchorage mount 57 with an anchorage 58 mounted thereto. Illustratively the frame 50 may but need not be of monolithic construction to include the anchorage mount 57. So too, the anchorage mount 57 and/or the side surfaces 54, 55 could be attached to the frame 50 by any suitable means, such as for example and without limitation by welding. A pair of generally aligned camming pin apertures 53 and a pair of generally aligned slots or channels 56 are defined through side walls 54 and 55. The camming pin apertures 53 are sized to receive therethrough a camming pin 52, which will be described below. The pair of slots or channels 56 are sized to receive therethrough mounting member 60 as will be explained herein below. The side walls 54 and 55 are spaced apart so as to receive and sandwich therebetween the lever 14, and a bias member 69, which may be for example and without limitation a spring 69, which spring 69 generally acts between the frame 50 and the lever 14 as will be explained herein below. Turning to coupling device 110, the mounting assembly 112 illustratively comprises an anchorage mount 57 with an anchorage 58 mounted thereto. Mounting assembly 112 may be attached to, or be integral with frame 113.
In either or both mounting assembly 12, 112, the anchorage 58, which for example and without limitation may be a D-ring, may be movably mounted to the anchorage mount 57. For example, the anchorage 58 may rotate or swivel generally about the longitudinal axis of anchorage mount 57. In addition, anchorage 58 and/or anchorage mount 57 may be detachable from the frame 13, 113 as desired. Referring to FIG. 10, the mounting assembly 12, 112 may be configured to attach or couple anchorage 58 to or with any manner of flexible, semi-flexible, semi-rigid or rigid elongate members or tethers 20, such as for example and without limitation, an animal or human leash, a web, a rope, a wire, a chain such as a key chain, or other suitable device or structure desired to be coupled to an anchor member. The tether 20 may be permanently, semi-permanently or releasably coupled to the anchorage through any suitable structure or method, such as for example and without limitation, sewing, snapping, clipping, riveting, gluing, hook and looping, bracketing, sliding association, and the like or any combination of the foregoing.
Frame 13, 113 is a generally monolithic structure illustratively having a substantially U-shaped transverse cross-section and is sized to fit snugly within cover 11, 111 and to receive therein the lever member 14, 114. The Frame 13, 113 may have upwardly extending sides as in the case of frame 13 of device 10 or be an inverse-U with downwardly extending sides as in the case, illustratively, of frame 113 of coupling device 110 or vice versa. Illustratively, as best seen in FIG. 4, frame 13 of coupling device 10 has a bottom surface 74, and a pair of spaced apart side surfaces or plates 71 and 72, which project upwardly from the bottom surface 74. The sides 71 and 72 each have a mounting aperture 76 configured to receive mounting member or fastener 60. Sides 71, 72 are spaced apart such that they fit within the housing or cover 11. The sides are also spaced apart so as to receive and sandwich therebetween the assembled mounting assembly 12 and its sub-components and the lever 14, which is received within the mounting assembly 12, as will be explained. Thus, the sides 54 and 55 of the mounting assembly nest between the upwardly extending sides 71, 72 of the frame 13, with the lever 14 nested between all sides 71, 72, 54, 55. The sides 71, 72 also define a mouth or notch 80 having a seat 82. The mouth 80 is sized to receive an anchor member, for example, the illustrative D-ring 16, which may be coupled to an animal's collar. The mouth may also be sized to receive other anchor members such as, for example, a loop in a web, or a suitable rigid member such as found in the lower anchorages in motor vehicles as mandated by FMVSS 213.
In contrast to the illustrative frame 13, frame 113, as best seen in FIG. 9, illustratively has a top surface 170 and a pair of generally downwardly projecting and spaced-apart side surfaces 171 and 172. Sides 171 and 172 are generally perpendicular to top surface 170 and bottom surface 174. Bottom surface 174 includes a generally arcuate-shaped portion and defines an opening or void 175 therethrough, which void 175 is in communication with or adjacent to void 29. The sides 171, 172 are also spaced apart so as to create a lever void 67 therebetween to receive and sandwich the lever 14. The void 67 is bounded by and in communication with the void 175, with top opening 173 formed through top surface 170, and with mouth 180 defined by sides 171, 172. Formed within lever void 67 is a bias void 68 sized to house the bias member 69. The mouth 180 is sized to receive an anchor member, for example, the D-ring 16 or other anchor member such as, for example, a loop in a web, or a suitable rigid member such as found in the lower anchorages in motor vehicles as mandated by for example FMVSS 213.
The frame 13, 113 may be made of any suitable metallic, non-metallic, or composite material, or combination thereof, and may be of monolithic, unitary, or non-monolithic construction. For example, frame sides 71 and 72 and/or 171 and 172 could be stand-alone plates coupled together using any standard coupling method, including welding, riveting, screwing, bolting, pinning and the like. As noted, though, the frame 13, 113 illustratively is of monolithic construction.
Lever 14, 114 is illustratively monolithic and made of metal and is sized to move relative to and inside the frame 13, 113 between sides 71 and 72, 171 and 172. Lever 14, 114 defines therethrough a mounting aperture or hole 89 configured to receive and move about mounting member 60. The distal end 87 of lever 14, 114 has a downwardly projecting tooth 88 having a leading or engagement edge 18. Tooth 88 illustratively is sized to cover the distal opening of mouths 36, 80, 180 when coupling 10, 110 is assembled and in its closed position as will be explained. Lever 14 illustratively includes between its proximate and distal ends the hole 89 and a rounded protrusion which defines camming pin recess 15, and at its proximate end a bias mount or engagement portion 17. Illustrative lever 114, in contrast, is generally S-shaped and includes between its proximate and distal ends a bias engagement portion 117 and a direct manipulation portion 19, and at or near its proximate end the mounting hole 89. It will be appreciated that the lever 14, 114 may be fashioned from any suitable metallic, non-metallic, or composite material, or any combination thereof, using any method of manufacture suitable to the material(s) being used. The lever may also be non-monolithic.
As best seen in FIGS. 2, 3A, 5, 7, 8A and 10, lever 14, 114 illustratively has a normally closed position where the bias member or spring 69 urges the tooth 88 to substantially close or cover the mouths 36, 80, 180, and, as seen in FIGS. 3B and 8B an open position where the tooth 88 is substantially removed from the mouths 36, 80, 180. More specifically, in the normally closed position the biasing member 69 urges the lever 14, 114 in a generally downwardly slope toward the respective bottom surfaces 28, 74, 128, 174 thereby substantially closing off the respective mouth(s) 36, 80, 180 with tooth 88. In the open position, the lever 14 is moved into a generally upwardly sloping configuration relative to the bottom surfaces 28, 74, 128, 174 thereby moving the tooth 88 substantially out of the way of respective mouth(s) 36, 80, 180. It will be appreciated the device 10, 110 could be configured to reverse the closed and open positions such that the lever 14, 114 and tooth 88 are normally urged upwardly to substantially cover the respective mouth(s) 36, 80, 180 and are movable downwardly to substantially uncover the respective mouth(s) 36, 80, 180. So too, horizontal or oblique movements of the lever 14, 114 to move between open and closed positions are within the knowledge of those skilled in the art and are desired to be protected. In any event, lever 14, 114 and tooth 88 may be cammed or moved to the open position, to substantially uncover respective mouths 36, 80, 180 by applying pressure to, or engaging the respective lever's 14, 114 leading or engagement edge 18. For example, the device 10, 110 may be urged, pressed or pushed onto an anchor member, for example anchor member 16, which impinges the engagement edge 18 of the tooth 88 and overcomes the bias force of biasing member 69 to cam or move the lever 14, 114 out of the way of the respective mouth(s) 36, 80, 180, either upwardly or downwardly, or otherwise, depending on how the device 10, 110 is configured. So too, the anchor member may be pressed into engagement with the engagement edge 18, or the coupling device 10, 110 and the anchor member 16 could be urged one against the other into engagement as desired. While both levers 14 and 114 may be cammed or moved to the open position as just described, each has at least one alternative way to be moved to the open position, and each may be urged into the closed position in alternative ways as will now be described in turn.
Referring to FIGS. 1-5, coupling device 10 is generally constructed and operates as follows. In its assembled configuration, as shown in FIG. 5, device 10 has nestled inside of cover 11, the mounting assembly 12, the frame assembly 13 and the lever 14. The lever 14 is sandwiched between side walls or surfaces 54 and 55, with spring 69 mounted to, or in contact at one end with bias mount 17 and in contact at the other end with frame 50. Fastener or mounting member 60 extends through coupling apertures 27 in the cover 11, mounting apertures 76 in the frame 13, mounting channels 56 in the mounting assembly 12 and mounting hole 89 located between the proximate and distal ends of lever 14 to movably mount the lever to the mounting assembly 12 and to fasten together the cover 11, the mounting assembly 12, and the frame assembly 13. Camming pin 52 extends through camming apertures 53 and camming pin recess 15.
In operation, spring 69 normally biases the lever 14 into the closed position, illustratively downwardly and somewhat forwardly, by acting between the frame 50 of mounting assembly 12 and the lever 14. It will be appreciated that the mounting assembly 12 and the frame assembly 13 could also be a unitary assembly. In any event, by coupling the two assemblies 12 and 13 together, they act as a unitary assembly such that the spring 69 is also acting between the lever 14 and the frame assembly 13. In addition to engaging the engagement edge 18 to cam the lever 14 to the open position as described above, the lever 14 may be moved to the open position through internal camming as follows. Illustratively, lever 14 may be cammed or moved from the closed position to the open position by a user gripping and applying pressure to one or more protrusions on the cover 11, such as for example the ears 41 and 42 or the upper surface 22 or forehead of the head in the vicinity of the eyes 44, while applying an opposite pressure to the proximate end of the device 10, for example to the mounting assembly 12, which will move forwardly within and with respect to the frame assembly 13 as the mounting member 60 moves within the channels 56. The camming pin 52 will move with the mounting assembly 12 in order to contact with the sides of the camming pin recess 15 to cam or move the lever 14 to uncover the mouth. This internal camming process will not only allow extraction of, or disengagement with an anchor member 16, but also will allow insertion of an anchor member 16 into the mouth(s) 36, 80.
Referring to FIGS. 6-10, coupling device 110 is generally constructed and operates as follows. In its assembled configuration, as shown in FIG. 10, device 110 has nestled inside of cover 111, the frame assembly 113 and the lever 114. The portions of the frame assembly 113 that define mouth 180 are sized to fit within the upper portion 32 and the lower portion 33 of cover 111 in order to align and place in communication with each other mouth 180 and mouth 36. As noted above and shown in FIG. 9, the mounting assembly 112 may be mounted directly to the frame assembly 113 forming a unitary frame, or the two assemblies 112 and 113 may form a monolithic frame. Illustratively, the lever 114 is generally S-shaped and is sandwiched between side walls or surfaces 171 and 172. The bias member or spring 69 is disposed within cavity 68 defined within the void 67 formed between the sides 171, 172. In the closed position, the direct manipulation portion 19 of lever 114 protrudes through openings 29 and 175. Fastener or mounting member 160 extends through coupling apertures 27 in the frame 113 and mounting hole 89 in the vicinity of the proximate end of lever 114 to movably mount the lever to the frame 113. It will be appreciated that mounting member 160 could also pass through the cover 111 in order to mount together the cover 111 and the frame assembly 113 in lieu of the illustrative snap-on embodiment. Also, the cover 111 could both be snapped onto the frame 113 and fastened together therewith by mounting member 160. So too, the cover 111 and frame 113 could be of monolithic construction.
In operation, spring 69 illustratively acts between top wall of frame assembly 113 and the spring mount or contact portion 117 of the lever 114 to urge the lever to the closed position so that the tooth 88 substantially covers or closes the mouth 36, 180. As described above and known to those skilled in the art, the engagement edge 18 may be engaged with an anchor member to cam or move the lever 114 to the open position. In addition, the lever 114 may be moved to the open position through direct manipulation as follows. Illustratively, lever 114 may be moved from the closed position to the open position by a user gripping and applying pressure to one or more protrusions on the cover 111, such as for example the ears 41 and 42 or the upper surface 122 or forehead of the head in the vicinity of the eyes 44, while applying pressure to the manipulation portion 19 of the lever 114. If desired, a user could also grasp at least a portion of the mounting assembly 112 when applying pressure to the manipulation portion 19. The pressure applied to the manipulation portion 19 illustratively will be generally opposite to the bias force of the spring 69 in order to move the lever 114 and its tooth 88 out of the closed position. Illustratively, the arcuate bottom surfaces 128, 174 allow the lever to be moved or pivoted by direct manipulation to the degree necessary to uncover the mouth 36, 180. As the lever 114 is moved to the open position, its distal end moves through the top opening defined in top surface 170. It will be appreciated, as noted above, that the open and closed positions could be reversed. In any event, the direct movement of the lever 114 out of the closed position will not only allow extraction of, or disengagement with an anchor member 16, but also will allow insertion of an anchor member 16 into the mouth(s) 36, 180 as one alternative to camming engagement. As shown in FIG. 10, another device or object, such as a leash or other suitable elongate member 20, may be coupled or attached to anchorage 58 if desired.
Not only does the housing or cover 11, 111 aid in the manual movement of lever 14, 114 to the open position by providing gripping protrusions in the form of ears 41 and 42, and forehead or top surface 22, 122 and eyes 44, but it also may protect the lever 14, 114 from dust, from chipping, and the like. In addition, anatomically correct or representative protrusions such as the ears 41, 42, forehead or top surface 22, 122, and eyes 44 allow a user to simultaneously maintain a grip on the coupling device 10, 110 while moving the lever 14, 114 to the open position in order to disengage the device 10, 110, even as such disengagement is being resisted. For example, an animal with a leash attached by the coupling device 10, 110 to the D-ring 16 anchor member on the animal's collar, might pull away from the coupling device 10, 110 as a user attempts to disconnect the coupling device 10, 110 from the animal. The mouth 36, 80, 180 with its dangling tooth 88 helps a user, even a child, intuitively know where to insert the anchor member 16 and aids in such insertion by guiding the anchor member into engagement. The cover 11, 111 also may help distinguish, by feel and/or by sight, one device, such as a leash or key chain, from another. For example, feel alone may help a user distinguish the leash for the collie from the leash for the schnauzer, or the keys for the Cadillac from the keys to the Mustang. So too, quick recognition by sight of the appropriate leash is facilitated by the recognizable shape and/or color of the cover 11, 111. The cover or housing may also provide temperature resistance from the bare metal of the frame assembly 13, 113 and/or mounting assembly 12, 112, if these assemblies are chosen to be made from metal, which they need not be. The cover also may protect finger nails. In addition to these many utilitarian aspects of the cover 11, 111, it also offers an aesthetically pleasing appearance. As already noted, each such cover or housing 11, 111 may be interchangeable one with the other as desired. For example, a particular connector device 10, 110 might have a housing or cover 11, 111 resembling a dog which may be removed and replaced with a different housing or cover 11, 111 resembling a cat. In another example, a blue housing or cover resembling a cocker spaniel might be replaced with a red housing or cover resembling a cocker spaniel or with a blue housing or cover resembling a bulldog. The cover may be configured with an illumination device and/or a sound chip to simulate, for example barking, meowing, purring, etc. Illustratively, the light from the illumination device could emanate from the eyes 44 and the sound from the sound chip could emanate from the mouth 36.
While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that one skilled in the art will recognize, and that it is desired to protect, all aspects, changes and modifications that come within the spirit of the invention.
