Abstract

A firearm accessory adjustment system is described. The system provides for independent elevation and windage adjustment for a laser associated with a firearm. Each of the elevation and windage adjustments can be made independently using single adjustments on the side of the firearm. The system can be integral to a sidearm.

First claim

What is claimed is:

1. An elevation adjuster for a firearm accessory comprising:
an elevation wedge having a first vertical surface and a first inclined plane normal to the first vertical surface, the inclined plane having a slope angle;
an elevation plunger having a contact surface for engaging an accessory, a second surface for engaging the first vertical surface and a second inclined plane for engaging the first inclined plane; and
an adjustment screw in contact with a surface of the elevation wedge wherein advancement of the adjustment screw moves the elevation wedge in a first direction and moves the elevation plunger in a second direction that is normal to the first direction.

2. The elevation adjuster of claim 1 comprising a biasing element that forces the firearm accessory toward the contact surface of the elevation plunger.

3. The elevation adjuster of claim 2 wherein the biasing element contacts the firearm accessory less than 170° around the firearm accessory from where the firearm accessory contacts the contact surface.

4. The elevation adjuster of claim 1 , wherein the adjustment screw is configured and arranged to move in the same direction as the slope angle.

5. The elevation adjuster of claim 1 , wherein the first and second inclined planes have the same slope angle.

6. The elevation adjuster of claim 1 , wherein the first inclined plane has a slope angle between 10° and 50°.

7. The elevation adjuster of claim 1 , wherein the firearm accessory comprises a laser housing.

8. The elevation adjuster of claim 1 , wherein the elevation plunger is seated in a pocket in a firearm and wherein the pocket prevents lateral movement of the elevation plunger.

9. A firearm comprising the elevation adjuster of claim 1 .

10. A sidearm comprising the elevation adjuster of claim 1 , wherein the firearm accessory is integral to a sidearm frame.

11. A method of adjusting an elevation of a laser mounted on a firearm, the method comprising:
rotating a screw to advance the screw in a first direction;
moving an elevation wedge laterally with a distal end of the screw;
contacting an elevation plunger with the elevation wedge to move the elevation plunger in a direction that is about 90° to the first direction; and
moving the laser in a vertical direction in unison with the elevation plunger.

12. The method of claim 11 further comprising reversing movement of the laser by rotating the screw in the opposite direction.

13. The method of claim 11 , wherein the laser moves about a fulcrum between a laser head and an elevation screw.
