Abstract

A bayonet assembly, for a firearm that has a knuckleguard, includes a rail connected to the firearm where the rail comprises a first position detent and a second position detent. The bayonet assembly may also include a bayonet that, in turn, includes a blade and a slide. The slide may be dimensioned and configured to engage the rail and the slide may include a slide catch that is dimensioned and configured to be engageable with the first position detent and the second position detent. In operation, the bayonet may be slid by a hand that is located within the knuckleguard from a remote position, where the slide catch engages the first position detent, to an extended position, where the slide catch engages the second position detent.

Claims

1. A bayonet assembly for a firearm including a knuckleguard, comprising:

a rail connected to the firearm and the rail comprising a first position detent and a second position detent; and

a bayonet comprising a blade and a slide, the slide being dimensioned and configured to engage the rail and the slide comprising a slide catch being dimensioned and configured to be engageable with the first position detent and the second position detent;

wherein the bayonet may be slid by a hand that is located within the knuckleguard from a remote position where the slide catch engages the first position detent to an extended position where the slide catch engages the second position detent.

2. The bayonet assembly of claim 1, further comprising a handle connected to the slide and the handle being dimensioned and configured to be gripped by either a left hand or a right hand of a soldier.

3. The bayonet assembly of claim 2, wherein:

the firearm comprises an outer cover including a slide port; and

the handle comprises a neck portion that extends through the slide port and has a generally arcuate shape in cross section.

4. The bayonet assembly of claim 1, wherein:

the rail comprises a generally trapezoidal shape in cross section; and

the slide comprises a central cavity being configured to correspond to the shape of the rail and for receiving the rail therein.

5. The bayonet assembly of claim 4, wherein:

the first position detent and the second position detent each comprise at least one resilient arm terminating in an angled tooth extending in a direction that is generally transverse from a longitudinal axis of the rail; and

the slide catch comprises at least one pivotable arm comprising a first end having a finger push portion and a catch portion configured to correspond with the angled tooth of the at least one resilient arm.

6. The bayonet assembly of claim 5, wherein:

the first position detent and the second position detent are disposed in spaced relation along the longitudinal axis of the rail and each comprise a pair of resilient arms located on opposing sides of the rail; and

the slide catch comprises a pair of pivotable arms located on opposing sides of the slide catch.

7. The bayonet assembly of claim 6, wherein each of the pivotable arms comprise at least one boss and the slide comprises at least one pair of corresponding depressions for snap locking each pivotable arm at a desired location.

8. A bayonet assembly for a firearm including a knuckleguard, comprising:

means for support connected to the firearm and comprising a first means for engaging and a second means for engaging;

means for sliding being dimensioned and configured to engage and reciprocate along the support means between the first means for engaging and the second means for engaging, the slide means comprising a third engaging means being dimensioned and configured to be selectively engageable with the first engaging means and the second engaging means and the slide means comprising means for cutting extending from the slide means;

wherein the cutting means may be reciprocated from a remote position to an extended position by hand while located within the knuckleguard.

9. The bayonet assembly of claim 8, wherein:

the support means comprises a rail and the first means for engaging comprises a first position detent and the second means for engaging comprises a second position detent; and

the slide means comprises a slide, the third engaging means comprises a slide catch and the cutting means comprises a blade;

wherein the bayonet may be slid by a hand located within the knuckleguard from a remote position where the slide catch engages the first position detent to an extended position where the slide catch engages the second position detent.

10. The bayonet assembly of claim 9, wherein the bayonet assembly further comprises a handle connected to the slide and wherein the handle is configured so that it may be gripped by either a left hand or a right hand of an operator.

11. The bayonet assembly of claim 10, wherein:

the firearm comprises an outer cover including a slide port; and

the handle comprises a neck portion that extends through the slide port and has a generally arcuate shape in cross section.

12. The bayonet assembly of claim 9, wherein:

the rail comprises a generally trapezoidal shape in cross section; and

the slide comprises a central cavity being configured to correspond to the shape of the rail and for receiving the rail therein.

13. The bayonet assembly of claim 12, wherein:

the first position detent and the second position detent each comprise at least one movable arm terminating in an angled tooth extending in a direction that is generally transverse from a longitudinal axis of the rail; and

the slide catch comprises at least one pivotable arm comprising a first end having a finger push portion and a catch portion configured to correspond with the angled tooth of the movable arm.

14. The bayonet assembly of claim 13, wherein:

the first position detent and the second position detent are spaced along the longitudinal axis of the rail and each comprise a pair of movable arms located on opposing sides of the rail; and

the slide catch comprises a pair of pivotable arms located on opposing sides of the slide catch.

15. The bayonet assembly of claim 14, wherein each of the pivotable arms comprise at least one boss and the slide comprises at least one pair of corresponding depressions for snap locking each pivotable arm at a desired location.
