Abstract

At least one cam lock and an opposing structure form a compression channel for receiving and engaging a pistol slide. When the pistol is moved in a certain direction through the compression channel, the one or more cam locks and opposing structure engage the pistol'"'"'s slide and translate some of the forward motion force into a compressive force on the sides of the slide. At a point where the compressive force overcomes the force of the main spring of the pistol, the pistol frame driven by the user moves forward relative to the slide, thereby racking the slide of the pistol.

Claims

1. An assistive device for operating a slide portion of a pistol comprising:

a base plate;

a first cam lock disposed on the base plate for receiving and frictionally engaging a first side of a slide portion of a pistol;

a counter structure disposed on the base plate and juxtaposed to the first cam lock providing a compression channel suitable for receiving a slide portion of a pistol and engaging a second side of the slide portion, configured to allow passing the slide portion through the compression channel while holding a grip portion of the pistol resulting in the first cam lock engaging the first side of the slide portion, the counter structure engaging the second side of the slide portion, and a compressive force to be applied from the first side to the second side to assist in driving the slide portion towards a rear of the pistol; and

a cushioning material disposed on a surface of the base plate within the compression channel.

2. The assistive device as set forth in claim 1 wherein a width of the compression channel ranges from essentially 0.70 inches to 1.50 inches.

3. The assistive device as set forth in claim 1 in which the first cam lock is a rotating cam lock.

4. The assistive device as set forth in claim 1 in which the first cam lock is a linear cam lock.

5. The assistive device as set forth in claim 1 in which the counter structure comprises a second cam lock.

6. The assistive device as set forth in claim 5 in which the second cam lock comprises a rotating cam lock.

7. The assistive device as set forth in claim 5 in which the second cam lock comprises a linear cam lock.

8. The assistive device as set forth in claim 1 in which the counter structure comprises a wall having a surface juxtaposed to the first cam lock.

9. The assistive device as set forth in claim 1 further comprising a device for attaching the base plate to one or more armament holding systems selected from the group consisting of a belt, a thigh rig, an ankle rig, a wrist rig, a glove, a vest, a back pack, a waist pack, a carry bag, and a piece of furniture.

10. The assistive device as set forth in claim 1 wherein the base plate is integral to an armament holding system.

11. The assistive device as set forth in claim 1 wherein the cushioning material prevents damage to a finish of a slide portion of a pistol.

12. The assistive device as set forth in claim 1 wherein the cushioning material disposed on a surface of the base plate frictionally engages a slide portion of a pistol.

13. A method for producing an assistive device for operating a slide portion of a pistol, the method comprising:

a base plate;

affixing a first cam lock to the base plate positioned for receiving and frictionally engaging a first side of a slide portion of a pistol;

affixing a counter structure mechanically juxtaposed to the first cam lock thereby defining a compression channel between the first cam lock and the counter structure, wherein the compression channel is suitable for receiving a slide portion of a pistol and engaging a second side of the slide portion, wherein passing the slide portion through the compression channel in a first direction while holding a grip portion of the pistol results in the first cam lock engaging the first side, the counter structure engaging the second structure, and a compressive force being applied from the first side to the second side to assist in driving the slide portion towards a rear of the pistol; and

affixing a cushioning material to the base plate in the compression channel.

14. The method as set forth in claim 13 wherein a width of the compression channel ranges from essentially 0.70 inches to 1.50 inches.

15. The method as set forth in claim 13 in which providing of the first cam lock comprises providing a rotating cam lock.

16. The method as set forth in claim 13 in which the providing of the first cam lock comprises providing a linear cam lock.

17. The method as set forth in claim 13 in the providing of the counter structure comprises providing at least one element selected from the group consisting of a rotating cam lock, a linear cam lock, and a surface juxtaposed to the first cam lock.

18. The method as set forth in claim 13 further comprising a device for attaching the base plate to one or more armament holding systems selected from the group consisting of a belt, a thigh rig, an ankle rig, a wrist rig, a glove, a vest, a back pack, a waist pack, a carry bag, and a piece of furniture.

19. The method as set forth in claim 13 wherein the base plate is integral to an armament holding system.

20. The method as set forth in claim 13 wherein the cushioning material comprises at least one material selected from the group consisting of a cushioning material and a frictional material.
