DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings, where like numerals identify like elements, there is shown an accessory mount 10 according to an exemplary embodiment of the invention. The accessory mount 10 includes an accessory receiver 12 adapted to receive and support an accessory, such as a light 14, and a base 16 adapted for receipt by an accessory rail system, such as rail system 18. As described below in greater detail, the accessory receiver 12 of the accessory mount 10 is adapted for pivot with respect to the base 16 of the accessory mount 10 mount is adapted To facilitate illustration of the invention, the accessory mount 10 is shown received by the accessory rail system 18, which has been secured to a plastic model 1911 pistol 20 with a mounting rail attached forward of the trigger guard. It should be understood, however, that the accessory mount 10 is not limited to use with any particular accessory rail system or on any particular firearm. Rail systems of the depicted type are available from Command Arms Accessories.

The accessory receiver 12 of the accessory mount 10 includes an elongated body 22 defining an inner bore 24. The inner bore 24 of body 22 has a rounded inner surface 26 facilitating receipt by the receiver 12 of an accessory having an elongated and generally rounded exterior such as the handle portion of a battery-powered light 14. It should be understood that the invention is not limited in scope to rounded bores receiving rounded accessories, however, and that bores and accessories having non-round configuration could be used.

The accessory receiver 12 includes a pair of support posts 28, 30 extending from one side of the body 22 of the receiver 12. As shown, the support posts 28, 30 are spaced apart from each other to provide for receipt of the base 16 of the accessory mount 10 between the support posts 28, 30. As may be seen in FIG. 10, the accessory mount 10 includes an elongated pin 32 for rotatably connecting the base 16 of the accessory mount 10 between the support posts 28, 30 of the accessory receiver 12. The pin 32 is received in aligned openings of the support posts 28, of the accessory receiver and through a bore 34 defined by the base 16.

The accessory mount 10 includes a compression spring 36 received on the pin 32. The compression spring 36 contacts support post 28 of accessory receiver 12 at one end of the spring 36 and an annular shoulder defined within the bore 34 of the base 16 at an opposite end of the spring 36. As should be understood, the action of the compression spring tends to urge the base 16 of accessory mount 10 away from support post 28 of accessory receiver 12 and towards support post 30.

Referring to FIGS. 11-15, the accessory mount 10 includes a locking mechanism 38 adapted for locking the accessory receiver 12 and base 16 of the accessory mount 10 against relative rotation in one of a plurality of preset angular positions. The locking mechanism 38 includes tab projections 40 carried by support post 30 that are adapted for receipt by slot openings 42 defined by the base 16. As shown in FIG. 15, the support post 30 includes three tab projections 40 angularly spaced from each other at 90 degree intervals about a lower half of the pin 32 (from the point of view shown in FIG. 15). As shown in FIG. 14, the base 16 of accessory mount 10 includes 8 slot openings 42 spaced from each other at 45 degree intervals about a centrally-located circular recess 44. This arrangement provides preset angular positions located at 45 degree intervals in which the tab projections 40 can engage the slot openings 42 to lock the receiver 12 and base 16 against relative rotation. It should be understood that it is not required that the support post 30 include 3 tab projections 40 and that the support post 30 could include only one tab projection 40 to provide the desired locking feature. The inclusion of 3 tab projections 40 as shown, however, provides added stability and balance for the locking mechanism 38.

To operate the locking mechanism 38, a user applies force to the receiver 12 to overcome the biasing force of the compression spring 36 to draw the base 16 away from the support post 30 and toward support post 28. In this condition, which is shown in FIGS. 11-13, the tab projections 40 are retracted (i.e., disengaged) from the slot openings 42, thereby permitting relative rotation between the receiver 12 and base 16 of the accessory mount 10.

Referring to FIGS. 1 through 4, the accessory mount 10 is shown in a first position in which the receiver 12 is located below the barrel of the piston model 20 (from the point of view shown in FIG. 5) substantially in line with both the barrel and the grip of the pistol model 20. Referring to FIGS. 14 and 15, the first position would result if the tab projections 40 of the locking mechanism 38 inserted into the slot openings 42 of the locking mechanism 38 in the orientations shown in FIGS. 14 and 15.

Referring to FIGS. 6 and 7, the accessory receiver 12 of the accessory mount 10 has been pivoted with respect to the base 16 of the accessory mount 10 to a second position. As shown in FIG. 7, the second position for the accessory receiver 12 is located 45 degrees in a clockwise direction (from the point of view shown in FIGS. 5 and 7) from that of the first position.

Referring to FIG. 8, the accessory receiver 12 of the accessory mount 10 has been pivoted with respect to the base 16 to a third position. As seen by comparing FIGS. 5 and 8, the third position for the accessory receiver 12 is located 90 degrees in a clockwise direction (from the point of view shown in FIGS. 5 and 8) from that of the first position.

Referring to FIG. 9, the accessory receiver 12 of the accessory mount 10 has been pivoted with respect to the base 16 to a fourth position. As seen by comparing FIGS. 5 and 9, the fourth position for the accessory receiver 12 is located 90 degrees in a counter-clockwise direction (from the point of view shown in FIGS. 5 and 9) from that of the first position. It should be understood that the accessory receiver 12 of the accessory mount 10 is also adapted to locate the accessory receiver 12 in a fifth position (not shown) with respect to the base 16 in which the accessory receiver 12 is located 45 degrees in a counter-clockwise direction (from the point of view shown in FIG. 5) from that of the first position.

The number of slot openings 42 provided in the base 16 of the accessory mount 10 could be varied from that shown such that the number of potential positions could be varied. Also it is not required that the tab projections 40 are included on the receiver 12 for engagement with slot openings 42 on the base 16. The interfitting elements of the locking mechanism 38 could be switched such that slot openings are defined by the receiver 12 for receiving tab projections carried by the base 16.

The base 16 of accessory mount 10 includes first and second legs 46, 48 located on opposite sides of the base 16. Each of the legs 46, 48 defines an elongated notch 50 on an inner surface of the leg 46, 48. As shown in FIG. 5 for example, the notches 50 in the base legs 46, 48 are adapted to receive opposite side edges of the rail system 18 in the manner of a dove-tail connection for securing the base 16 to the rail system 18. As described above, the rail system 18 is known and no further description is needed.

Referring to FIGS. 13 and 16, the second leg 48 of base 16 is removably secured to the base 16 to facilitate attachment of the base to rail system 18. As shown in FIG. 16, the base 16 of accessory mount 10 includes a fastener 52 for securing the second leg 48 to the base 16. In FIG. 13, the base 16 is shown with the second leg 48 removed.

The foregoing describes the invention in terms of embodiments foreseen by the inventor for which an enabling description was available, notwithstanding that insubstantial modifications of the invention, not presently foreseen, may nonetheless represent equivalents thereto.
