Shotgun hollow buttstock adapter

Abstract

The shotgun hollow buttstock adapter is designed to fit within the rear portion of a hollow shotgun buttstock, enabling users to mechanically fasten recoil pads to the buttstock. This adapter addresses the need for a simple, efficient, and secure method of attaching recoil pads to shotguns with hollow stocks, thereby enhancing recoil management and user comfort.

Claims

1. An adapter for use with a firearm hollow stock to affix accessories, the adapter comprising: a plate, the plate having an outer edge, front face, and a back face; a chamfer along an entire junction between the back face and the outer edge, creating a chamfered edge; the plate held within the firearm hollow stock by a lip of the firearm hollow stock engaged with the outer edge of the plate; two or more holes through the plate; the two or more holes configured to affix the accessories to a rear of the firearm hollow stock; and wherein the chamfered edge is configured for insertion of the plate into the firearm hollow stock and then to be rotated into place within the firearm hollow stock with less deformation of the firearm hollow stock than if the plate lacked the chamfer; wherein the plate is solid except for the two or more holes.

DETAILED DESCRIPTION

[0030] Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Throughout the following detailed description, the same reference numerals refer to the same elements in all figures. Referring to FIG. 1, a view of a shotgun buttstock is shown.

[0031] The shotgun 200 is shown with grip 204 and stock 202 with butt 206.

[0032] Referring to FIG. 2, a second view of a shotgun buttstock is shown.

[0033] The shotgun 200 is again shown with stock 202, with butt 206 having butt face 208. Within the hollow stock 202 is a cavity 220.

[0034] Within the end of the cavity, near the butt face 208, is a lip 222 adjacent to ribs 224, each rib 224 with a rib face 226.

[0035] Inside of the lip 222 is a support face 228 against which the adapter plate 110 will rest when installed (see FIG. 7).

[0036] Referring to FIGS. 3 and 4, a rear isometric view and a front isometric view of the shotgun hollow buttstock adapter are shown.

[0037] The adapter plate 110 includes a top 112 and bottom 114, left 116 and right 118 and edge 124.

[0038] The front face 120 faces toward the user after installation (see FIG. 6). The back face 122 faces inward and includes a chamfer 126 that helps the adapter plate 110 to rotate into position while minimizing distortion to the stock 202.

[0039] The adapter plate 110 includes a tapered shape to match the profile of the support faces 228 of the ribs 224 within the cavity 220 of the stock 202 (see FIG. 2). The upper taper 128 is the tapered shape from the center to the top 112, and the lower taper 130 is the tapered shape from the center to the bottom 114.

[0040] Also shown is the central hole 132 and mounting holes 134, which are optionally threaded.

[0041] The preferred dimensions of the adapter plate are 4.475 inches tall, 1.292 inches wide, and 0.25 inches thick.

[0042] The central hole 132 is preferably 0.805 inches in diameter. The mounting holes 134 are preferably drilled and threaded for #8-32 UNC screws.

[0043] Referring to FIG. 5, a first view of the shotgun hollow buttstock adapter during installation is shown.

[0044] The adapter plate 110 is started at approximately a 90 angle into the stock 202, the chamfer 126 intended for rotation toward the inside of the stock 202.

[0045] Referring to FIG. 6, a second view of the shotgun hollow buttstock adapter during installation is shown.

[0046] The adapter plate 110 is rotated, causing outward deformation of the walls of the stock 202. A tool 230, such as a screwdriver, is optionally used to generate the required torque to rotate the adapter plate 110 into place. The tool 230 is shown placed through the central hole 132.

[0047] Referring to FIG. 7, a third view of the shotgun hollow buttstock adapter during installation is shown.

[0048] The adapter plate 110 is shown in its final installed position, with the front face 120 visible. The outer perimeter of the front face 120 rests against the support face 228 of the lip 222.

[0049] Referring to FIGS. 8 and 9, a first view and a second view after installation of the recoil pad to the shotgun hollow buttstock adapter are shown.

[0050] A pad 240 is shown installed against the butt 206 of the stock 202. Screws 242 pass through the pad 240, interfacing with the mounting holes 134 of the adapter plate 110 (see FIG. 4).

[0051] Referring to FIG. 10, a third view after installation of the recoil pad to the shotgun hollow buttstock adapter of the shotgun hollow buttstock adapter is shown.

[0052] The adapter plate 110, within the stock 202, rests against the support face 228 of the lip 222 (see FIG. 2).

[0053] Referring to FIG. 11, a second embodiment of the shotgun hollow buttstock adapter is shown.

[0054] In this embodiment, the adapter plate 110 includes the edge 124 with chamfer 126, and mounting holes 134 with central hole 132. Secondary holes 136 are added to support alternative recoil mechanisms that require additional mounting holes or the ability to pass through the adapter plate 110.

[0055] Referring to FIG. 12, a second embodiment of the shotgun hollow buttstock adapter with active recoil adapter after installation of the shotgun hollow buttstock adapter is shown.

[0056] The adapter plate 110 is used to mount a recoil absorption device 250 to the stock 202.

[0057] Referring to FIGS. 13A and 13B, a shotgun hollow buttstock is shown with and without the chamfered edge to show the change in length.

[0058] In FIG. 13A, the adapter plate 110 is shown with 90 corners 140, or corners without chamfers.

[0059] In FIG. 13 B, the adapter plate 110 is shown with chamfer 126.

[0060] By virtue of the chamfer 126, distance D from corner A to chamfered corner B is less than distance D from corner A to corner B.

[0061] The result is during installation of the adapter plate 110 within the stock 202, while the adapter plate 110 is being rotated in installation rotation direction 150, the deformation of the stock 202 (see FIG. 6) that is required to allow the adapter plate 110 to reach its final position is reduced. In other words, the chamfer 126 reduces the amount that the stock 202 must outwardly deform to allow the adapter plate 110 to rotate into position.

[0062] Equivalent elements can be substituted for the ones set forth above such that they perform in substantially the same manner in substantially the same way for achieving substantially the same result.
