Abstract

An accessory mount for a firearm, that may be quickly, easily and firmly secured to a firearm, and quickly and easily removed from the firearm. In combination with a firearm including a receiver, a barrel longitudinally extending from the receiver, and a lug secured to the firearm above the barrel, the accessory mount includes a longitudinal mount body positioned along the barrel with the mount body'"'"'s rear end supported by the receiver, a lever pivotally secured to the mount body'"'"'s front end about a first transverse axis, the lever pivotally secured to the lug about a second transverse axis spaced along the lever from the first transverse axis, and a longitudinally adjustable member carried by the mount body for urging the lever to pivot about the second transverse axis to rearwardly urge the mount'"'"'s rear end against the receiver.

Claims

1. An accessory mount for a firearm having a longitudinal barrel and a receiver, the accessory mount comprising the combination of:

a longitudinal mount body having a front end and a rear end, said mount body positionable along the barrel with said rear end supported by the receiver;

a lever pivotally secured to said mount body about a first transverse axis at said front end, said lever pivotally securable to the firearm about a second transverse axis spaced along said lever from said first transverse axis; and

a longitudinally adjustable member carried by said mount body for urging said lever to pivot about said first transverse axis.

2. The accessory mount according to claim 1, wherein:

said second transverse axis is spaced along said lever above said first transverse axis.

3. The accessory mount according to claim 2, wherein:

said longitudinally adjustable member contacts said lever below said first transverse axis.

4. The accessory mount according to claim 3, wherein:

said longitudinally adjustable member is a set screw within a threaded aperture longitudinally through said front end of said mount body.

5. The accessory mount according to claim 1, wherein:

said lever includes a U-shaped portion having two legs spaced apart by a distance greater than the diameter of the barrel of the firearm.

6. The accessory mount according to claim 5, wherein:

said lever includes a portion depending from said U-shaped portion for being contacted by said longitudinally adjustable member.

7. The accessory mount according to claim 5, the firearm including a lug secured thereto above the barrel, wherein:

said legs are pivotally securable to said lug about said second transverse axis with the barrel disposed within the U of said lever.

8. The accessory mount according to claim 1, the firearm including a groove in said receiver about said barrel, wherein:

said rear end of said mount body includes at least one rearwardly extending projection insertable in said groove for supporting said rear end.

9. The accessory mount according to claim 1, the firearm including a groove in said receiver about said barrel, wherein:

said rear end of said mount body includes two rearwardly extending tabs insertable in said groove for supporting said rear end.

10. The accessory mount according to claim 9, wherein:

said tabs include rearwardly facing surfaces and said groove includes a forwardly facing surface, said rearwardly facing surfaces of said tabs being urged against said forwardly facing surface of said groove when said lever is urged by said longitudinally adjustable member.

11. The accessory mount according to claim 1, wherein:

said longitudinally adjustable member is adjustable for urging said lever to pivot about said second transverse axis for rearwardly urging said rear end of said mount body against the receiver when said lever is pivotally secured to the firearm with said rear end supported by the receiver.

12. The accessory mount according to claim 11, wherein:

said second transverse axis is spaced along said lever above said first transverse axis.

13. The accessory mount according to claim 12, wherein:

said longitudinally adjustable member contacts said lever below said first transverse axis.

14. The accessory mount according to claim 13, wherein:

said longitudinally adjustable member is a set screw within a threaded aperture longitudinally through said front end of said mount body.

15. The accessory mount according to claim 11, wherein:

said lever includes a U-shaped portion having two legs spaced apart by a distance greater than the diameter of the barrel of the firearm.

16. The accessory mount according to claim 15, wherein:

said lever includes a portion depending from said U-shaped portion for being contacted by said longitudinally adjustable member.

17. The accessory mount according to claim 15, the firearm including a lug secured thereto above the barrel, wherein:

said legs are pivotally securable to said lug about said second transverse axis with the barrel disposed within the U of said lever.

18. The accessory mount according to claim 11, the firearm including a groove in said receiver about said barrel, wherein:

said rear end of said mount body includes at least one rearwardly extending projection insertable in said groove for supporting said rear end.

19. The accessory mount according to claim 11, the firearm including a groove in said receiver about said barrel, wherein:

said rear end of said mount body includes two rearwardly extending tabs insertable in said groove for supporting said rear end.

20. The accessory mount according to claim 19, wherein:

said tabs include rearwardly facing surfaces and said groove includes a forwardly facing surface, said rearwardly facing surfaces of said tabs being urged against said forwardly facing surface of said groove when said lever is urged by said longitudinally adjustable member.

21. Firearm and accessory mount apparatus, comprising in combination:

a firearm including a receiver and a barrel longitudinally extending from said receiver;

a lug secured to said firearm above said barrel;

a longitudinal mount body having a front end and a rear end, said mount body positioned along said barrel with said rear end supported by said receiver;

a lever pivotably secured to said mount body about a first transverse axis at said front end of said mount body, said lever pivotally secured to said lug about a second transverse axis spaced along said lever from said first transverse axis; and

a longitudinally adjustable member carried by said mount body for urging said lever to pivot about said second transverse axis to rearwardly urge said rear end against said receiver.

22. The apparatus according to claim 21, wherein:

said firearm includes a groove in said receiver about said barrel; and

said rear end of said mount body is supported within said groove.

23. The apparatus according to claim 22, wherein:
