## Background
FIELD OF THE INVENTION
The present invention generally relates to vehicle motorcycle accessories. More particularly, the invention concerns a mechanism for mounting a saddlebag to a motorcycle.
BACKGROUND OF THE INVENTION
The popularity of motorcycling continues to increase. Riders are attracted to the freedom of the open road, leaving behind the cares and worries of everyday life. Motorcycle manufacturers have seized upon the recent surge in popularity and have been selling motorcycles and accessories in record numbers.
Obviously, motorcycles cannot carry as many items as motor vehicles. In order to provide as much carrying capacity as possible, saddlebags are attached to the motorcycle. A motorcycle may have saddlebags for carrying the rider's personal gear, repair tools or other items. One saddlebag is typically mounted to a bracket attached to the frame rearward of the rider's seat on each side of the motorcycle. Although many saddlebags are made of leather, others are made of fiberglass or a similar rigid material.
Saddlebags generally must be removed to perform any significant maintenance on the motorcycle. Removing a saddlebag may be inconvenient and time consuming because the saddlebag is often bolted to the mounting bracket, which in turn is bolted to the frame of the motorcycle. For example, to remove each saddlebag from the HARLEY-DAVIDSON HERITAGE motorcycle, one must unscrew four bolts to detach the saddlebag from the mounting bracket and unscrew three bolts to detach the mounting bracket from the frame. Obviously, this is time consuming and very inconvenient.
Therefore, there exists a need for an apparatus that enables the quick and easy mounting and removal of motorcycle saddlebags.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the quick-release mechanism with safety collar (hereafter “QRMS”) that embodies principals of the present invention. It will be apparent, however, to one skilled in the art that the QRMS may be practiced without some of these specific details. Throughout this description, the embodiments and examples shown should be considered as exemplars, rather than as limitations on the QRMS. That is, the following description provides examples, and the accompanying drawings show various examples for the purposes of illustration. However, these examples should not be construed in a limiting sense as they are merely intended to provide examples of the QRMS rather than to provide an exhaustive list of all possible implementations of the QRMS.
Specific embodiments of the invention will now be further described by the following, non-limiting examples which will serve to illustrate various features. The examples are intended merely to facilitate an understanding of ways in which the invention may be practiced and to further enable those of skill in the art to practice the invention. Accordingly, the examples should not be construed as limiting the scope of the invention. In addition, reference throughout this specification to “one embodiment” or “an embodiment” means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner in one or more embodiments. As used herein, the “present invention” refers to any one of the embodiments of the invention described herein, and any equivalents. Furthermore, reference to various feature(s) of the “present invention” throughout this document does not mean that all claimed embodiments or methods must include the referenced feature(s).
The present invention relates to a quick-release mounting system having a safety collar for a motorcycle saddlebag and a method for retrofitting a motorcycle with the system. The system includes two or more coupling assemblies with which one can retrofit a motorcycle by replacing bolts of the original mounting system with the coupling assemblies. Each coupling assembly comprises a first coupling portion and a second coupling portion that can be removably coupled and uncoupled to one another in a quick-release manner. In addition, each coupling assembly includes a safety collar that prevents an unintentional, or accidental uncoupling of the coupling assembly.
Referring now to FIGS. 1-2, a saddlebag assembly 10 is mounted on a motorcycle (shown in phantom line). As illustrated in FIG. 2, saddlebag assembly 10 includes a saddlebag (shown in phantom line) and a mounting bracket 12. A portion 14 of mounting bracket 12 is tubular and a portion 16 is plate-like. As shown in FIGS. 4 and 5, the saddlebag is attached to mounting bracket 12 by two bolts 18 that extend through holes in the inboard side of the saddlebag wall 20 and are received in two threaded studs 22 in plate-like portion 16 and by one bolt 24 that extends through another hole in the inboard side of saddlebag wall 20 and is received in the threaded stud 26 on tubular portion 14. Grommets 28 in these holes damp any vibration. Saddlebag assembly 10 is attached, more or less permanently, to a fender brace portion of the frame 32 of the motorcycle by two bolts (not shown) that extend through a pair of holes in plate-like portion 16 and frame 32 and by a third bolt (not shown) that extends through a hole 34 in tubular portion 14. Specifically, the former two bolts are screwed into internally threaded studs (not shown), which have threaded shanks that are in turn secured to the fender brace portion of frame 32 by nuts (not shown) in the conventional manner. The latter or third bolt extends not only through hole 34 but also through a hole in bracket extension 36 and is secured to by a nut. Bracket extension 36 is in turn bolted to frame 32, typically by a foot peg 37. The above-described structure is well-known in the art, as it exists on the Harley-Davidson Heritage motorcycle, as well as other Harley-Davidson motorcycles (Harley-Davidson is a registered trademark of H-D Michigan, Inc., of Ann Arbor Mich.). Prior to retrofitting the motorcycle in accordance with the present invention, the only way to remove saddlebag assembly 10 is to remove the three bolts that secure it to frame 32.
To retrofit the motorcycle in accordance with the present invention, one removes the bolts, studs, and nuts that, as described above, secure saddlebag assembly 10 to frame 32. As illustrated in FIG. 2, two or more of the bolts and their corresponding studs or nuts are each replaced with the quick-release mechanism with safety collar (hereafter “QRMS”) of the present invention. For example, in place of each of the two bolts that formerly secured plate-like portion 16 of bracket 12, a receiving element 40 is attached to plate-like portion 16. In place of each of the two studs that were formerly secured to fender brace portion of frame 32, a mounting element 38 is attached. In place of the third bolt, which was formerly attached to bracket extension 36 and secured tubular portion 14 to bracket extension 36, a coupling member 39 is attached to bracket extension 36. Each mounting element 38 is removably mateable in a quick-release manner with each female receiving element 40. Once mounted, the quick-release collar 41 is positioned over portions of both the mounting and receiving elements 38, 40 thereby preventing the inadvertent separation of the two elements, 38 and 40.
The structure of each coupling element and the manner in which it is attached is illustrated in further detail in FIGS. 4-6. Each female receiving element 40 includes a threaded shank 66 that terminates in a coupling portion that includes two wrench flats 68 and a semi-cylindrical slot 70 sized to receive a cylindrical head, or male element 72 on the mounting element 38. A semi-cylindrical raised channel 74 is located adjacent to the slot 70, the raised channel 74 having an elevated shoulder 76 that abuts an end of the slot 70. The elevated shoulder 76 is formed, in part, because the diameter of the slot 70 is greater than the diameter of the raised channel 74. As shown in FIG. 4, threaded shank 66 extends through one of the holes in the plate-like portion 16 of bracket 12 and is secured by a washer 58 and a nut 60. The original elastomeric grommet 62 remains in the hole to damp vibration.
Referring again to FIGS. 4-6, the mounting element 38 includes a threaded shank 56, a cylindrical male element 72 located at a distal end, and a bolt head 54 located between the threaded shank 56 and the male element 72. A locking cylinder, or cylindrical element 78 is located between the male element 72 and the bolt head 54. The locking cylinder 78 has a diameter that is smaller than the diameter of the male element 72. As shown in FIG. 4, threaded shank 56 extends through one of the holes in the fender brace portion of frame 32 and is secured by a washer 48 and a nut 50. Coupling member 39, shown in FIG. 2, which attaches tubular portion 14 to bracket extension 36, has a similar structure and is mounted in essentially the same manner. That is, it has a threaded shank (not shown) that extends through the hole in bracket extension 36 and is secured by another washer 48 and nut 50 (not shown in FIG. 2). It further has an enlarged cylindrical elastomeric bushing that abuts bracket extension 36 to damp vibration.
Referring now to FIGS. 7-8, the mounting and receiving elements, 38 and 40, removeably attached together are illustrated. The male element 72 is placed in slot 70, and simultaneously, as a result of the arrangement of elements, the locking cylinder 78 is located in raised channel 74. The male element 72 is now securely engaged, as the head of the male element 72 contacts the solid face of the receiving element 40 adjacent to the wrench flats 68. The other end of the male element 72, which comprises a cylindrical flange, contacts the semi-cylindrical elevated shoulder 76. With both ends of the male element 72 securely captured, any significant relative movement between the mounting and receiving elements, 38 and 40, is eliminated.
In addition, the quick-release safety collar 41 can be placed over the male element 72, thereby preventing inadvertent disengagement of the male element 72 from the slot 70. Spring 80 abuts the safety collar 41, as shown in FIGS. 7-8, so that one end of the safety collar 41 is forced against semi-cylindrical flange 82, shown in FIGS. 5-6. The flange 82 is located at the distal end of the receiving element 40, comprises a semi-cylindrical shape, and is formed by the distal end of the receiving element 40 having a diameter larger than the diameter of the adjacent portion of the receiving element 40. FIG. 7 shows the safety collar 41 in a retracted position, and FIG. 8 shows the safety collar 41 in the engaged position, covering the male element 72 and slot 70. Although the embodiment described above discusses the shapes of the mating parts as cylindrical, in other embodiments the mating parts may have other suitable shapes.
To mount saddlebag assembly 10 on the motorcycle using the mounting and receiving elements 38 and 40, one orients saddlebag assembly 10 such that the male element 72 is laterally adjacent to slot 70. Preferably, the receiving element 40 containing the slot 70 is mounted on the saddlebag (as described above) in an orientation in which slot 70 faces downward with respect to the ground. With that orientation, one can mount saddlebag assembly 10 by lowering it until the male element 72 is fully received in slot 70. As this procedure occurs, the safety collar 41 is pulled back into the position shown in FIG. 7. Then once the male element 72 is fully received in slot 70, the safety collar 41 is released, whereby spring 80 pushes the safety collar 41 against flange 82, so that the male element 72 and slot 70 are covered by the safety collar 41, which prevents disengagement of the male element 72 from the slot 70. Finally, with reference to FIG. 2, a plug portion of coupling member 39 is inserted through hole 34 in tubular portion 14 of bracket 12 and is secured by cotter pin 64. Other motorcycle saddlebags 10 may not require the third connection using the cotter pin 64.
To remove the saddlebag assembly 10 from the motorcycle, one can quickly and easily retract the safety collar 41, and lift upwards on the saddlebag, thereby disengaging the male element 72 from the slot 70.
The present invention allows one to quickly and easily mount and dismount a motorcycle saddlebag without the use of tools and without reaching into the saddlebag. A motorcycle such as the Harley-Davidson Heritage can be retrofitted by replacing the original bolt system with the quick-release coupling system of the present invention. Although the present invention is particularly suitable for such retrofitting, it can alternatively be included as original equipment on a motorcycle.
