Abstract

An interface for coupling a bipod to a sling stud of a firearm forend. The interface can include two pawls that pivot to release or grasp the sling stud. The pawls can be biased upward via a detent that rides within a vertical aperture in a pivot holder. The pivot holder can move up and down within a vertical aperture in a mounting plate of the interface, and via this movement the pawls may be forced open or closed. A bottom surface of one or both pawls can include an irregular surface different portions of which interface with a top of the detent depending on a vertical position of the pivot holder within the aperture in the mounting plate.

First claim

What is claimed is:

1. A bipod comprising:
a housing comprising at least two leg assemblies and a housing aperture,
the housing aperture configured to slidably pass a pivot rod through the housing aperture,
the pivot rod having a threaded coupling and configured to couple to a locking knob positioned below the housing,
wherein revolving the locking knob repositions the pivot rod along a vertical axis passing through the pivot rod and the housing aperture;

a firearm forend interfaces affixed to a top of the pivot rod and configured to rotate around the pivot rod;
a pivot block positioned between the housing and the firearm forend interface and configured to pivot atop the housing,
wherein the pivot block comprises a concave hollow portion into which a portion of a bottom of the firearm forend interface is configured to rest in such that as the locking knob is tightened, the pivot block and the firearm forend interface pivot in unison;
a sling stud clasp assembly positioned within an aperture in the firearm forend interface; and

at least two legs coupled to the housing.

2. The bipod of claim 1 , further comprising:
at least two pawls pivotally coupled to each other and to pivot holder via a pivot pin;
wherein at least one of the at least two pawls includes a pawl detent at a first radius from the pivot pin;
the pawl detent is arranged at least partially within a vertical aperture in the pivot holder; and
a biasing component is arranged within the vertical aperture and below the pawl detent, the biasing component configured to apply a bias to a bottom of the pawl detent.

3. The bipod of claim 2 , further comprising:
a locking mechanism;
wherein when the locking mechanism is rotated in a first direction, the pivot holder, the pawl detent, and the pivot pin move upward, and via interaction of a top of the pawl detent and an irregular bottom surface of at least one of the at least two pawls, two of the at least two pawls are forced upward and pivot outward toward an open position.

4. The bipod of claim 2 , wherein one or two of the at least two pawls includes an irregular bottom surface.

5. The bipod of claim 4 , wherein the irregular bottom surface includes a pawl detent and a pawl groove.

6. The bipod of claim 5 , wherein the pawl detent is at a first radius from the pivot pin and the pawl groove is at a second radius from the pivot pin, wherein the first radius is greater than the second radius.

7. A firearm assembly comprising:
a firearm having a forend and a barrel;
a housing comprising at least two leg assemblies and a housing aperture,
the housing aperture configured to slidably pass a pivot rod through the housing aperture,
the pivot rod having a threaded coupling and configured to couple to a locking knob positioned below the housing,
wherein revolving the locking knob repositions the pivot rod along a vertical axis passing through the pivot rod and the housing;
a firearm forend interface affixed to a top of the pivot rod, configured to rotate around the pivot rod, and having a vertical aperture shaped to receive a pivot holder;
a pivot block positioned between the housing and the firearm forend interface and configured to pivot atop the housing,
wherein the pivot block comprises a concave hollow portion into which a portion of a bottom of the firearm forend interface is configured to rest in such that as the locking knob is tightened, the pivot block and the firearm forend interface pivot in unison;
at least two legs coupled to the housing;
a sling stud clasp assembly positioned within an aperture in the firearm forend interface;

two pawls pivotally coupled to each other and to the pivot holder via a pivot pin; and
a sling stud locking mechanism threadingly coupled to the pivot holder and configured to, via rotation of the sling stud locking mechanism, cause vertical movement of the pivot holder,
wherein movement of the pivot holder within the vertical aperture in a first direction causes opening of the two pawls and movement of the pivot holder within the vertical aperture in a second direction causes closing of the two pawls.

8. The firearm assembly of claim 7 , wherein:
at least one of the two pawls includes a pawl detent at a first radius from the pivot pin;
the pawl detent is arranged at least partially within a vertical aperture in the pivot holder; and
a biasing component is arranged within the vertical aperture and below the pawl detent, the biasing component configured to apply a bias to a bottom of the pawl detent.

9. The firearm assembly of claim 8 , wherein when the sling stud locking mechanism is rotated in a first direction, the pivot holder, the pawl detent, and the pivot pin move upward, and via interaction of a top of the pawl detent and an irregular bottom surface of at least one of the two pawls, both pawls are forced upward and pivot outward toward an open position.

10. The firearm assembly of claim 7 , wherein when the sling stud locking mechanism is rotated in a first direction, the pivot holder, a pawl detent, and the pivot pin move upward, and via interaction of a top of the pawl detent and an irregular bottom surface of at least one of the two pawls, both pawls are forced upward and pivot outward toward an open position.

11. The firearm assembly of claim 7 , wherein one or both of the pawls includes an irregular bottom surface.

12. The firearm assembly of claim 11 , wherein the irregular bottom surface includes a pawl detent and a pawl groove.

13. The firearm assembly of claim 12 , wherein the pawl detent is at a first radius from the pivot pin and the pawl groove is at a second radius from the pivot pin, wherein the first radius is greater than the second radius.

14. The bipod of claim 1 , wherein the at least two legs are rotationally coupled to the housing.

15. The bipod of claim 1 , wherein the at least two legs are configure to telescope to be stored in a folded-up position and back to a position near a forend of a firearm.

16. The bipod of claim 3 , wherein the sling stud clasp assembly comprises a clevis configured to prevent the sling stud clasp assembly and the locking mechanism from pulling apart or decoupling when the sling stud locking mechanism is rotated in a second direction.

17. The bipod of claim 2 , further comprising a lock aperture configured to receive the pivot holder.

18. The firearm assembly of claim 7 , wherein the at least two legs are configured to telescope to be stored in a folded-up position and back to a position near the forend of the firearm.

19. The firearm assembly of claim 7 , wherein the sling stud clasp assembly comprises a clevis configured to prevent the sling stud clasp assembly and the sling stud locking mechanism from pulling apart and decoupling when the sling stud locking mechanism is rotated in second direction.

20. The firearm assembly of claim 7 , further comprises a lock aperture configured to receive the pivot holder.
