Abstract

A rest for a pistol having a takedown passage and defining a major side plane. The rest comprises a post configured to be closely received by the passage; a planar rest element pivotally connected to the post and movable between an active position perpendicular to the side plane and a retracted position parallel to the side plane; and the rest element being biased to the active position.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Patent Application No. 63/233,561, filed on Aug. 16, 2021, entitled “PISTOL FOLDING THUMB REST”, which is hereby incorporated by reference in its entirety for all that is taught and disclosed therein.

FIELD OF THE INVENTION

The present invention relates to thumb rests for pistols.

BACKGROUND AND SUMMARY

Recoil can be intimidating for anyone learning to fire a pistol.
Recoil can cause a shooter to miss his target or to drop the pistol.
The above disadvantage is addressed by a rest for a pistol having a takedown passage and defining a major side plane. The rest comprises a post configured to be closely received by the passage; a planar rest element pivotally connected to the post and movable between an active position perpendicular to the side plane and a retracted position parallel to the side plane; and the rest element being biased to the active position.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a view of the left side, showing shows the two main components of the thumb rest assembly.

FIG. 2 is a view of the left side, illustrating the thumb rest opened to 180 degrees (while holstered).

FIG. 3 is a top view, illustrating the top view of the thumb rest opened to 180 degrees (while holstered).

FIG. 4 is an exploded view, illustrating all the individual components.

FIG. 5 is a view of the rear of thumb pad, illustrating the rear of the thumb rest.

FIG. 6 is an off angle view to show the takedown lever assembly (round area and outer arm) with the thumb rest attached in the closed detent position.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

FIG. 1 . (Left side) This illustration shows the two main components of the thumb rest assembly. Part 1 (Main Arm Body) is parallel to the firearm frame and part(s) 3 and 4 of the thumb rest plate are perpendicular (90 degrees) to the firearm frame in detent position.
Item 1: illustrates (1 of 2) of the main components of the assembly as it replaces the factory takedown lever on the Sig Sauer P320 Series of pistols. (Like designs of this folding part can/will be adapted for other firearms at any later date whether they are takedown lever, trigger pin, frame (lower) or picatinny mounted.
Item 2: illustrates the M4 screw hole through the item 1 assembly for uses of a M4×0.50 proprietary set screw (described in a later FIG. 4 ).
Item 3 and 4: illustrates bottom (item 3) and top (item 4) of the thumb rest area. The off-hand thumb is placed on the area indicated in item 4 on the left side of the firearm acting as a rest to significantly reduce recoil due to the thumb pressing forward at 55 degrees and interrupting the upward rotation of the muzzle when firing a firearm.
FIG. 2 . (Left side) illustrates the thumb rest opened to 180 degrees (while holstered) exposing the torsion spring (item 5), and hinge area between the lower arm (item 1) and the bottom of the thumb rest (item 3-4). The torsion spring (item 5) is responsible for providing torsion to detent the thumb rest (item 5) back to the detent angle of 90 degrees after the thumb rest (item 3-4) clears the holster body.
FIG. 3 . (Top view) illustrates the top view of the thumb rest opened to 180 degrees (while holstered). (Item 6) shows the hinge pin that runs through the hinge assembly and torsion spring and providing a fulcrum point for items 3 and 4 to rotate between 90 degrees to 180 degrees.
Item 9: illustrates the area perpendicular to the main arm body that retains the guide rod and spring.
FIG. 4 . (Exploded view) illustrates all the individual components.
Item 7: illustrates the set screw that fits through the main arm body to fit in the guide channel of the lower to stop any rotation downward.
Item 8: illustrates the screwdriver slot in the far right side of the thumb rest to aid in removal of the center cam area in the event of breakage.
FIG. 5 . (rear of thumb pad) illustrates the rear of the thumb rest highlighting the texture on the thumb area in a 90 degree detent position.

Claims

I claim:

1. A rest for a pistol having a takedown passage and defining a major side plane, the rest comprising:

a post configured to be closely received by the passage;

a planar rest element pivotally connected to the post and movable between an active position perpendicular to the side plane and a retracted position parallel to the side plane; and

the rest element being biased to the active position.
