Abstract

A bayonet lug clamp and mount assembly is provided for use with a rifle having a T-shaped bayonet lug with slots formed in a central portion thereof. A housing is configured to slidingly engage the bayonet lug. A lever incorporating an accessory mounting rail is pivotally coupled to the housing for movement towards and away therefrom. A jaw is movably mounted in the housing and has teeth that are aligned with the slots in the bayonet lug when the housing is slid thereon. A piston/cylinder assembly is coupled to the lever and to the jaw. When the lever is pivoted towards the housing with the teeth aligned with the slots in the bayonet lug, the piston/cylinder assembly presses the jaw against the bayonet lug as the teeth engage the slots. The lever can be locked to the housing in order to assure that the clamp does not move when the rifle is fired.

Claims

1. A bayonet lug clamp for use with a rifle having a T-shaped bayonet lug with slots formed in a central portion thereof, said bayonet lug clamp comprising:

a housing configured to slidingly engage the T-shaped bayonet lug;

a lever pivotally coupled to said housing for movement towards and away therefrom;

a jaw movably mounted in said housing, said jaw having teeth protruding therefrom, said teeth alignable with the slots in the bayonet lug when said housing is slid thereon; and

a piston/cylinder assembly having a cylinder pivotally coupled to said lever and having a piston slidingly supported partially within said cylinder and coupled to said jaw wherein, when said lever is pivoted towards said housing with said teeth aligned with the slots in the bayonet lug, said piston/cylinder assembly presses said jaw against the bayonet lug as said teeth engage the slots.

2. A bayonet lug clamp as in claim 1 further comprising an accessory mounting rail coupled to said lever and facing away from said housing when said lever is pivoted toward said housing.

3. A bayonet lug clamp as in claim 1 wherein said housing includes at least one stop for abutting a portion of the bayonet lug as said housing is slid thereon, wherein said teeth are aligned with the slots in the bayonet lug.

4. A bayonet lug clamp as in claim 1 further comprising means for locking said housing to said lever after said piston/cylinder assembly has pressed said jaw against the bayonet lug wherein said teeth remain engaged with the slots.

5. A bayonet lug clamp as in claim 4 further comprising means for unlocking said means for locking wherein said lever can be pivoted away from said housing.

6. A bayonet lug clamp as in claim 1 further comprising a spring coupled between said piston and said cylinder, wherein said spring is fully compressed as said lever pivots toward said housing wherein said piston/cylinder assembly becomes an axially rigid assembly.

7. A bayonet lug clamp for use with a rifle having a T-shaped bayonet lug with slots formed in a central portion thereof, said bayonet lug clamp comprising:

a housing configured to slidingly engage the T-shaped bayonet lug in a complementary fashion;

a lever pivotally coupled on an end thereof to an end of said housing for movement towards and away therefrom;

a jaw mounted in said housing for pivoting movement and sliding movement relative to said housing, said jaw having teeth protruding therefrom, said teeth alignable with the slots in the bayonet lug when said housing is slid thereon; and

a piston/cylinder assembly having a cylinder pivotally coupled to said lever inboard of said end of said lever, said piston/cylinder assembly further having a piston slidingly supported partially within said cylinder and coupled to said jaw wherein, when said lever is pivoted towards said housing with said teeth aligned with the slots in the bayonet lug, said piston/cylinder assembly compresses to form an axially rigid assembly that causes said pivoting movement and said sliding movement and presses said jaw against the bayonet lug as said teeth engage the slots.

8. A bayonet lug clamp as in claim 7 further comprising an accessory mounting rail coupled to said lever and facing away from said housing when said lever is pivoted toward said housing.

9. A bayonet lug clamp as in claim 7 wherein said housing includes at least one stop for abutting a portion of the bayonet lug as said housing is slid thereon, wherein said teeth are aligned with the slots in the bayonet lug.

10. A bayonet lug clamp as in claim 7 further comprising means for locking said housing to said lever and for bearing against said jaw after said piston/cylinder assembly has pressed said jaw against the bayonet lug wherein said teeth remain engaged with the slots.

11. A bayonet lug clamp as in claim 10 further comprising means for unlocking said means for locking wherein said lever can be pivoted away from said housing.

12. A bayonet lug clamp as in claim 10 wherein said means for locking is a spring-loaded plunger mounted in said housing to continually bear against said jaw.

13. A bayonet lug clamp as in claim 7 further comprising a spring coupled between said piston and said cylinder, wherein said spring is fully compressed as said lever pivots toward said housing wherein said piston/cylinder assembly becomes said axially rigid assembly.

14. An accessory mount assembly for use with a rifle having a T-shaped bayonet lug with slots formed in a central portion thereof, said assembly comprising:

a housing open on an end thereof to slidingly engage the T-shaped bayonet lug in a complementary fashion;

an elongated mounting rail pivotally coupled on an end thereof to said end of said housing for movement towards and away therefrom;

a jaw mounted in said housing for pivoting movement and sliding movement relative to said housing, said jaw having teeth protruding therefrom, said teeth alignable with the slots in the bayonet lug when said housing is slid thereon; and

a spring-loaded piston/cylinder assembly having a cylinder pivotally coupled to said lever inboard of said end of said mounting rail, said piston/cylinder assembly further having a piston slidingly supported partially within said cylinder and coupled to said jaw wherein, when said lever is pivoted towards said housing with said teeth aligned with the slots in the bayonet lug, said piston/cylinder assembly compresses to form an axially rigid assembly that causes said pivoting movement and said sliding movement and presses said jaw against the bayonet lug as said teeth engage the slots.

15. An assembly as in claim 14 wherein said housing includes at least one stop for abutting a portion of the bayonet lug as said housing is slid thereon, wherein said teeth are aligned with the slots in the bayonet lug.

16. An assembly as in claim 14 further comprising means for locking said housing to said mounting rail and for bearing against said jaw after said piston/cylinder assembly has pressed said jaw against the bayonet lug wherein said teeth remain engaged with the slots.

17. An assembly as in claim 16 further comprising means for unlocking said means for locking wherein said mounting rail can be pivoted away from said housing.

18. An assembly as in claim 16 wherein said means for locking is a spring-loaded plunger mounted in said housing to continually bear against said jaw.
