(9) As shown in
(10) The receiver 20 of the fastener 10 further comprises a head portion 23 at the lengthwise end of the receiver 20 opposite the shank portion 21. Head portion 23 may or may not, as desired, be provided with an annular lip 24 configured to abut against an outer surface 16 of the second object 14 when the shank portion 21 is fully engaged within the opening, recess or insert 15 of the second object 14. If provided, the lip 24 thereby functions as a mechanical stop for the head portion 23 of the receiver 20 against the outer surface 16 of the second object 14. Alternatively, or in addition, an elastomeric mount, standoff, washer, lock washer or the like (not shown) may be disposed between the head portion 23 of the receiver 20 and the outer surface 16 of the second object 14. Regardless, the head portion 23 defines a lengthwise, centrally disposed internal recess 25 extending in the direction of the shank portion 21 of the receiver 20 for receiving the insert 30, as will be described in greater detail hereafter. If desired, the periphery of the head portion 23 may be formed with a standard hexagonal geometry such that a conventional wrench or hex head socket (not shown) can be used to turn the head portion 23 so that the external threads 22 on the shank portion 21 of the receiver 20 engage with the internal threads provided within the opening, recess or insert 15 on the second object 14.
(11) The insert 30 of fastener 10 comprises a shank portion 31 at one lengthwise end and a head portion 33 at the other lengthwise end of the insert 30 opposite the shank portion 31. Shank portion 31 is configured (i.e., sized and shaped) to be inserted through an opening 12 formed in the first object 11 and to be subsequently releasably and removably received within the recess 25 provided in the head portion 23 of the receiver 20. The head portion 33 of the insert 30 is configured (i.e., sized and shaped) to engage with an outer surface 13 of the first object 11. If desired, an optional grommet 40 made of a resilient material, such as an elastomeric plastic, composite or rubber, may be disposed within the opening 12 formed through the first object 11 to prevent the outer surface 13 of the first object 11 from directly contacting the outermost end of the head portion 23 of the receiver 20 and/or the innermost end of the head portion 33 of the insert 30, and thereby reduce the possibility of damage to the outer surface 13 of either side of the first object 11. In one embodiment, a retainer element, such as an elastomeric washer, metal retaining washer or the like (not shown), may alternatively or additionally be disposed on the shank portion 31 of the insert 30 to retain the first object 11 on the insert 30 when the shank portion 31 is not within the receiver 20. If desired, the retainer element may be removed at the time the insert 30 is inserted into the receiver 20. In this manner, the first object 11 is securely retained on the insert 30 by the retainer element alone, or in combination with the grommet 40, to reduce the possibility that the insert 30 may become separated from the first object 11 and then misplaced or lost. Regardless, insert 30 defines a generally hollow interior configured (i.e., sized and shaped) to house a release mechanism 50 operable for releasably engaging the shank portion 31 of the insert 30 with the head portion 23 of the receiver 20, as will be described in greater detail hereafter with reference to
(12)
(13) With the receiver 20 secured on the second object 14, the first object 11 is positioned onto the shank portion 31 of the insert 30 (if not already retained thereon) with the optional grommet 40 disposed within the opening 12 formed through the first object 11. Alternatively, as previously described, the first object 11 optionally may be retained on the shank portion 31 of the insert 30 by the retainer element (not shown) such that the insert 30 remains with the first object 11 and the possibility of the insert 30 being misplaced or lost is reduced. Regardless, the shank portion 31 of the insert 30 with the first object 11 positioned thereon is inserted into the recess 25 defined by the head portion 23 of the receiver 20. If necessary, as will be described hereafter with reference to
(14) As will be described hereafter with reference to
(15)
(16) The release mechanism 50 further comprises a biasing element, for example a conventional coil spring 55 disposed between the lip 54 adjacent the head portion 53 of the release mechanism 50 and the shank portion 31 of the insert 30. The spring 55 is operable to bias the lip 54 of the release mechanism 50 against the interior of the head portion 33 of the insert 30. As such, spring 55 retains the head portion 53 of the release mechanism 50, and consequently the shank portion 51, in a fully outward position, also referred to herein as a retaining configuration. The release mechanism 50 further comprises at least one, and preferably a pair, of detent elements 56 configured (i.e., sized and shaped) to engage with an annular recess or groove 27 formed in the head portion 23 of the receiver 20 within the interior of the recess 25. By way of example and not limitation, the detent elements 56 may comprise spherical balls having a relatively small diameter and made of a relatively inelastic material, such as hard plastic, composite or metal (e.g., steel). Regardless, the detent elements 56 are disposed at least partially in the groove 27 formed within the recess 25 of the head portion 23 of the receiver 20 when the shank portion 51 of the release mechanism 50 is in the retaining configuration illustrated in
(17) In particular, the groove 57 formed in the shank portion 51 is aligned with the detent elements 56 when the release mechanism 50 is moved from the retaining configuration to a releasing configuration by pressing the head portion 53 of the release mechanism 50 inwardly against the biasing force of the spring 55. As a result, spring 55 is compressed and the shank portion 51 of the release mechanism 50 is moved within the hollow interior of the shank portion 31 of the insert 30 in the direction of the head portion 23 of the receiver 20. Consequently, the detent elements 56 move from the groove 27 formed within the recess 25 defined by the head portion 23 of the receiver 20 into the groove 57 formed in the shank portion 51 of the release mechanism 50. With the release mechanism 50 in the releasing configuration, the shank portion 31 of the insert 30 may be withdrawn from the head portion 23 of the receiver 20 to detach the first object 11 from the second object 14. Likewise, the shank portion 31 of the insert 30 may be inserted (or re-inserted) into the recess 25 defined by the head portion 23 of the receiver 20 when the release mechanism 50 is in the releasing configuration. It will be readily understood and appreciated that the first object 11 can be attached (or re-attached) to the second object 14 by releasing inward pressure on the head portion 53 of the release mechanism 50 while the detent elements 56 of the shank portion 51 are aligned with the groove 27 formed within the recess 25 of the head portion 23 of the receiver 20 so that the release mechanism 50 returns to the retaining configuration with the detent elements 56 disposed within the groove 27.
(18) As shown in
(19) It will be readily understood and appreciated by those skilled in the art that other suitable release mechanisms exist for releasably securing insert 30 to receiver 20, and consequently, for releasably attaching first object 11 to second object 14 in a manner that allows the first object 11 to be readily attached to and subsequently removed from the second object 14. By way of example, a quick-release fastener may comprise an insert for being releasably secured within a corresponding receiver. The insert may comprise a shank portion having a radial opening and one or more detent elements that are biased in a radially outward direction by an elastic coil spring disposed within the radial opening. The detent elements may be operable to move inwardly against the biasing force of the coil spring as the shank portion is inserted into a complementary recess defined by a head portion of the receiver. With the shank portion of the insert disposed within the recess of the receiver, the biasing force of the coil spring moves the detent elements outwardly into an annular groove formed within the interior of the recess. The insert is thereby releasably attached to the receiver and can be removed by applying pulling the insert outward with sufficient force to overcome the radially outward biasing force of the coil spring that retains the detent elements within the annular groove formed within the recess defined by the head portion of the receiver. A release mechanism of this alternative type, however, suffers from the disadvantage that the insert can be removed from the receiver by merely grasping and pulling the insert with a sufficient force to overcome the biasing force of the coil spring retaining the detent elements within the annular groove of the receiver. Consequently, the first object can become detached from the second object inadvertently, or can be readily detached by an unauthorized individual intentionally with little effort.
(20)
(21) The manufacturer of the vehicle 64 typically provides two or more internally threaded openings, recesses or inserts 65 in the surface 66 of the vehicle 64 and a corresponding plurality of externally threaded screws or bolts (not shown) for attaching a permanent license plate or a temporary license plate, such as dealer plate 61, to the vehicle 64. Only two (2) such internally threaded openings, recesses or inserts 65 are shown herein in
(22) The quick-release fastener 60 of the present invention is used in place of the threaded screws or bolts provided by the manufacturer so that the dealer plate 61 can be readily attached to the vehicle 64 and subsequently removed from the vehicle 64 without the use of a tool and without damaging the surface 66 of the vehicle 64. The automobile dealership first removes the externally threaded screws or bolts provided by the manufacturer from the internally threaded openings, recesses or inserts 65 in the surface 66 of the vehicle 64. As shown in the particularly advantageous embodiment illustrated in
(23) Regardless, the externally threaded shank portions 71 of the receivers 70 of the quick-release fasteners 60 are threaded into the corresponding internally threaded openings, recesses or inserts 65 in the rear surface 66 of the vehicle 64. As previously mentioned with respect to fastener 10, the head portion 73 of the receiver 70 of each quick-release fastener 60 may be provided with a hexagonal-shaped geometry to be engaged by a conventional wrench or hex head socket. Alternatively, as previously mentioned, the interior of the head portion 73 of the receiver 70 may be formed with one or more slots, such as slots 26 of fastener 10 depicted in
(24) With the receivers 70 of the quick-release fasteners 60 secured to the surface 66 of the vehicle 64, the automobile dealership can use inserts 80 to readily attach the dealer plate 61 to the vehicle 64, for example to allow a customer to test drive the vehicle 64 on a public roadway, and to subsequently remove the dealer plate 61 from the vehicle 64 following the test drive. The automobile dealership attaches the dealer plate 61 to the vehicle 64 by inserting the inserts 80 into the corresponding receivers 70 of the quick-release fasteners 60. As previously mentioned with respect to fastener 10, the dealer plate 61 may be pre-positioned on the shank portions 81 of the inserts 80 and retained thereon by elastomeric grommets 90 and/or by a retaining washer or the like (not shown) for purposes of convenience and to reduce the possibility that the inserts 80 become misplaced or lost. Grommets 90 and/or elastomeric washers or the like may also be positioned between the dealer plate 61 and the head portion 83 of the insert 80 so as to reduce the likelihood of damage to the surface 63 of the dealer plate 61. Regardless, the dealer plate 61 is disposed between the head portion 73 of the receiver 70 and the head portion 83 of the insert 80 of each quick-release fastener 60.
(25) Each quick-release fastener 60 further comprises a release mechanism 100 functionally equivalent to the release mechanism 50 previously described with respect to fastener 10. As such, the dealer plate 61 can be readily attached to the vehicle 64 by pressing the release mechanism 100 of each quick-release fastener 60, inserting the shank portion 81 of the insert 80 into the head portion 73 of the corresponding receiver 70, and then releasing the release mechanism 100 such that the shank portion 81 of the insert 80 is retained within the head portion 73 of the receiver 70 in the manner previously described with respect to fastener 10. Subsequently, the dealer plate 61 can be readily removed from the vehicle 64, for example following the test drive or when the vehicle 64 is sold, by gripping the head portion 83 of the insert 80 of each quick-release fastener 60, pressing the release mechanism 100, and removing the shank portion 81 of the insert 80 from the head portion 73 of the corresponding receiver 70, as previously described with respect to fastener 10.
(26)
(27) The slot 127 of the receiver 120 is configured (i.e., sized and shaped) to receive a conventional screw, bolt or other type of fastener 124 therein. As shown in
(28) Regardless of the foregoing description and illustration of various exemplary embodiments of the invention, the optimum structure of the invented device, and the manner of use, operation and steps of the invented methods, as well as reasonable equivalents thereof, are deemed to be readily apparent and understood by those skilled in the art. Accordingly, equivalent structures to those shown in the accompanying drawing figures and corresponding functions described in the written description are intended to be encompassed by the present invention and the appended claims, the foregoing being considered as illustrative only of the general concept and principles of the invention. Furthermore, since numerous modifications and changes will readily occur to those skilled in the art, the exemplary embodiments disclosed herein are not intended to limit the invention to the specific configuration, construction, materials, manner of use and operation shown and described. Instead, all reasonably predictable and suitable structural and functional equivalents of the invention, as well as obvious modifications and variants thereto, should be construed as falling within the scope of the invention as defined by the appended claims given their broadest reasonable construction and interpretation in view of the accompanying written description and drawing figures.
