Abstract

Apparatus for mounting optical sights or other weapon accessories which locates the weapon accessories (e.g. optical sights, laser range finders, night scopes, etc.) at a reduced distance relative to the position of the barrel of a weapon.

Claims

1. A mount apparatus for mounting a weapon accessory to a weapon mounted rail system having at least one rail, the at least one rail including a plurality of ribs disposed thereon, the plurality of ribs defining a plurality of spaces comprising channels, each channel having a width and a depth, and each channel being spaced a distance C_d from the adjacent channel;

the improvement wherein said mount apparatus comprises;

a frame comprising a first longitudinal frame member and a second longitudinal frame member, said first longitudinal frame member being spaced from said second longitudinal frame member; and

said first longitudinal frame member including a rail engaging surface;

means for attaching a weapon accessory to said mount apparatus;

biasing means operable to bias said rail engaging surface against a first rail surface of said weapon mounted rail system; and

a plurality of cross members connecting said first longitudinal frame member to said second longitudinal frame member, said plurality of cross members defining a plurality longitudinal openings located there between, said openings extending a distance substantially between said first longitudinal frame member and said second longitudinal frame member, each said opening being so shaped such as to be capable of accepting one of the plurality of ribs of said weapon mounted rail system.

2. The mount apparatus according to claim 1 further including a biasing member which is movable along an axis of said at least one cross member;

and

wherein said biasing means is capable of biasing said biasing member against a second rail surface of the weapon mounted rail system.

3. The mount apparatus according to claim 2 wherein said rail engaging surface of said first longitudinal frame member comprises a first beveled surface for engagement with the first rail surface of the weapon mounted rail system.

4. The mount apparatus according to claim 3 wherein said biasing member includes a second beveled surface for engagement with the second rail surface of the weapon mounted rail system.

5. The mount apparatus according to claim 4 wherein said mount apparatus includes at least two cross members.

6. The mount apparatus according to claim 4 wherein when said biasing means is operated, said biasing means biases said biasing member in a direction along an axis of said cross member.

7. The mount apparatus according to claim 1 wherein said biasing means comprises a threaded member cooperatively engaged to a threaded aperture located in one of said first or said second longitudinal frame members.

8. The mount apparatus according to claim 1 wherein said biasing means comprises an elliptical cam member having a lever member attached thereto, said lever member being operable to engage a surface of said elliptical cam member to a second rail surface of the weapon mounted rail system.

9. The mount apparatus according to claim 6 wherein said biasing means comprises an elliptical cam member having a lever member attached thereto, said lever member being operable to engage a contacting surface of said elliptical cam member to a surface of said biasing member thereby to bias said biasing member in said direction along an axis of said cross member.

10. The mount apparatus according to claim 5 wherein said at least two cross members are spaced a distance C_m apart from one another which is substantially equal to the distance C_d between the channel members of the weapon mounted rail system.

11. The mount apparatus according to claim 10 wherein the number of said cross members is selected from a number between 3-7 and wherein each of said cross members is spaced a distance C_m from the adjacent cross member.

12. In combination, a universal weapon mount and the mount apparatus according to claim 1, wherein when said mount apparatus is attached to the weapon mounted rail system, said at least one cross member is located within one of said channels.

13. The combination of claim 12 wherein said mount apparatus further includes a biasing member which is movable along an axis of said at least one cross member;

and

wherein said biasing means is capable of biasing said biasing member against a second rail surface of the weapon mounted rail system.

14. The combination of claim 13 wherein said rail engaging surface of said first longitudinal frame member comprises a first beveled surface for engagement with the first rail surface of the weapon mounted rail system.

15. The combination of claim 14 wherein said biasing member includes a second beveled surface for engagement with the second rail surface of the weapon mounted rail system.

16. The combination of claim 15 wherein when said biasing means is operated, said biasing means biases said biasing member in a direction along an axis of said cross member.

17. The combination of claim 16 wherein said biasing means comprises an elliptical cam member having a lever member attached thereto, said lever member being operable to engage a surface of said elliptical cam member to a surface of said biasing member thereby to bias said biasing member in said direction along an axis of said cross member.

18. The combination of claim 17 wherein said mount apparatus includes at least two cross members and wherein said at least two cross members are spaced a distance C_m apart from one another which is substantially equal to the distance C_d between the channel members of the weapon mounted rail system.

19. The mount apparatus according to claim 4 wherein said accessory attachment means comprises a threaded aperture for threadable communication with a threaded member such that said threaded member is capable of coupling said mount apparatus to a weapon accessory device.

20. A mount apparatus for mounting a weapon accessory to a weapon mounted rail system having at least one rail, the at least one rail including a plurality of ribs disposed thereon, the plurality of ribs defining a plurality of spaces comprising channels, each channel having a width and a depth, and each channel being spaced a distance C_d from the adjacent channel;

the improvement wherein said mount apparatus comprises;

a frame comprising a first longitudinal frame member and a second longitudinal frame member, said first longitudinal frame member being spaced from said second longitudinal frame member;

means for attaching a weapon accessory to said mount apparatus;

biasing means operable to attach said mount apparatus to said weapon mounted rail system; and

a plurality of cross members connecting said first longitudinal frame member to said second longitudinal frame member, said plurality of cross members defining a plurality of longitudinal openings located there between, said openings extending a distance substantially between said first longitudinal frame member and said second longitudinal frame member, each said opening being so shaped such as to be capable of accepting one of the plurality of ribs of said weapon mounted rail system.

21. The mount apparatus according to claim 20 wherein said mount apparatus includes at least two cross members and wherein said at least two cross members are spaced a distance C_m apart from one another which is substantially equal to the distance C_d between the channel members of the weapon mounted rail system.

22. The mount apparatus according to claim 21 wherein the number of said cross members is selected from a number between 3-7 and wherein each of said cross members is spaced a distance C_m from the adjacent cross member.

23. The mount apparatus according to claim 20 wherein said biasing means comprises an elliptical cam member having a lever member attached thereto, said lever member being operable to engage a surface of said elliptical cam member to a surface of the weapon mounted rail system thereby to secure said mount apparatus to the weapon mounted rail system.
