Abstract

A mounting device for the purpose of mounting various sighting apparatus on the raised vented rib of shotguns and various other weapons is disclosed. A mounting device that attaches to any suspended rail is disclosed. The device is characterized by a channeled piece of material designed to customly accept a flat plate of material within the inner surface walls of the extending arms of said channel and connected together by screws through mating holes to create a clamp-like device when the flat plate of material is placed beneath the suspended rail and the channel piece is placed on top of the suspended rail and mated to the flat plate and drawn together with screws to create a mounting surface on top of the suspended rail for use with various sighting apparatus. The device is affixed with centering and alignment means and braces that allow for adjusting to the various distances between the suspending posts of the rail, for stabilizing and for recoil absorption. The device can be formed, shaped and otherwise configured to work in conjunction with other practical mounting methods.

Claims

1. Device for mounting sighting apparatus comprising, in combination:

means for drawing the upper plate and the lower plate together to clamp the upper plate and the lower plate to the raised vented rib.

2. The mounting device of claim 1 wherein the drawing means comprises at least first and second threaded screws, with the upper plate including at least first and second clearance holes, with the lower plate including at least first and second threaded holes aligned with the first and second clearance holes, with the first and second clearance holes located on opposite sides of the raised vented rib, with the first and second threaded holes located on opposite sides of the raised vented rib, with the first and second threaded screws passing through the clearance holes of the upper plate and being threadably received in the threaded holes of the lower plate to draw the lower plate toward the upper plate.

3. The mounting device of claim 2 further comprising in combination:

means for centering and aligning the upper plate on top of the raised vented rib.

4. The mounting device of claim 3 wherein the centering and aligning means comprises, in combination:

at least a first side surface extending from the upper plate; and

means affixed to the side surface for adjusting the upper plate on the vented rib.

5. The mounting device of claim 4 wherein the adjusting means comprises at least a first screw threadably received in the side surface for abutting with the raised vented rib.

6. The mounting device of claim 5 wherein the centering and aligning means further comprises, in combination:

a second side surface, with the upper plate and the first and second side surfaces forming a channel.

7. The mounting device of claim 3 further comprising, in combination:

at least a first stabilization and recoil reduction brace affixed to the upper plate.

8. The mounting device of claim 7 wherein the raised vented rib is elevated from the weapons by a post;

and wherein the stabilization and recoil reduction brace comprises, in combination;

a flat wall affixed to the upper plate; and

a flat surface angled from the flat wall to fit between the raised vented rib and the weapon and to brace against the post.

9. The mounting device of claim 8 wherein the stabilization and recoil reduction brace further comprises, in combination:

a slot formed in the flat wall, with the stabilization and recoil reduction brace affixed to the upper plate by a screw passing through the slot and threadably received in the upper plate allowing the flat wall to be extended and retracted relative to the upper plate.

10. Device for mounting sighting apparatus on weapons having a raised vented rib comprising, in combination:

an upper plate for resting on top of the raised vented rib;

a lower plate for placement beneath the raised vented rib and between the raised vented rib and the weapon; and

means for drawing the upper plate and the lower plate together to clamp the upper plate and the lower plate to the raised vented rib comprising at least first and second threaded screws, with the upper plate including at least first and second clearance holes, with the first and second clearance holes of the upper plate being countersunk, with the lower plate including at least first and second threaded holes aligned with the first and second clearance holes, with the first and second clearance holes located on opposite sides of the raised vented rib, with the first and second threaded holes located on opposite sides of the raised vented rib, with the first and second threaded screws passing through the clearance holes of the upper plate and being threadably received in the threaded holes of the lower plate to draw the lower plate toward the upper plate.

11. Device for mounting sighting apparatus on weapons having a raised vented rib comprising, in combination:

an upper plate for resting on top of the raised vented rib;

a lower plate for placement beneath the raised vented rib and between the raised vented rib and the weapon;

means for drawing the upper plate and the lower plate together to clamp the upper plate and the lower plate to the raised vented rib; and

means for removably mounting attachment bases of the sighting apparatus to the upper plate.

12. The mounting device of claim 11 wherein the removably mounting means comprises at least a first threaded hole formed in the upper plate.

13. Device for mounting sighting apparatus on weapons having a raised vented rib comprising, in combination:

an upper plate for resting on top of the raised vented rib;

a lower plate for placement beneath the raised vented rib and between the raised vented rib and the weapon;

means for drawing the upper plate and the lower plate together to clamp the upper plate and the lower plate to the raised vented rib; and

means for centering and aligning the upper plate on top of the raised vented rib.

14. The mounting device of claim 13 wherein the centering and aligning means comprises, in combination:

at least a first side surface extending from the upper plate; and

means affixed to the side surface for adjusting the upper plate on the vented rib.

15. The mounting device of claim 14 wherein the adjusting means comprises at least a first screw threadably received in the side surface for abutting with the raised vented rib.

16. The mounting device of claim 15 wherein the centering and aligning means further comprises, in combination:

a second side surface, with the upper plate and the first and second side surfaces forming a channel.

17. Device for mounting sighting apparatus on weapons having a raised vented rib comprising, in combination:

an upper plate for resting on top of the raised vented rib;

a lower plate for placement beneath the raised vented rib and between the raised vented rib and the weapon;

means for drawing the upper plate and the lower plate together to clamp the upper plate and the lower plate to the raised vented rib; and

at least a first stabilization and recoil reduction brace affixed to the upper plate.

18. The mounting device of claim 17 wherein the raised vented rib is elevated from the weapon by a post;

and wherein the stabilization and recoil reduction brace comprises, in combination;

a flat wall affixed to the upper plate; and

a flat surface angled from the flat wall to fit between the raised vented rib and the weapon and to brace against the post.

19. The mounting device of claim 18 wherein the stabilization and recoil reduction brace further comprises, in combination:

a slot formed in the flat wall, with the stabilization and recoil reduction brace affixed to the upper plate by a screw passing through the slot and threadably received in the upper plate allowing the flat wall to be extended and retracted relative to the upper plate.
