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 assembly comprising:
a firearm forend interface having a vertical aperture shaped to receive a pivot holder;
the pivot holder shaped to slidingly move vertically with the vertical aperture in the firearm forend interface;
two pawls pivotally coupled to each other and to the pivot holder via a pivot pin;
a sling stud locking mechanism threadingly coupled to the pivot holder and configured to cause the vertical movement of the pivot holder via rotation,
wherein upward vertical movement of the pivot holder causes opening of the two pawls and downward vertical movement of the pivot holder causes closing of the two pawls.

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

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

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

5. The bipod assembly of claim 4 , wherein when the locking mechanism is rotated in a first direction, the pivot holder, detent, and pivot pin move upward, and via interaction of a top of the detent and an irregular bottom surface of at least one of the pawls, both pawls are forced upward and tend to pivot outward toward an open position.

6. The bipod assembly of claim 1 , wherein when the locking mechanism is rotated in a first direction, the pivot holder, detent, and pivot pin move upward, and via interaction of a top of the detent and an irregular bottom surface of at least one of the pawls, both pawls are forced upward and tend to pivot outward toward an open position.

7. The bipod assembly of claim 1 , wherein one or both of the pawls includes an irregular bottom surface.

8. The bipod assembly of claim 7 , wherein the irregular bottom surface includes a pawl detent and a pawl groove.

9. The bipod assembly of claim 8 , 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.

10. A firearm assembly comprising:
a firearm having a forend;
a firearm forend interface configured for coupling to a bottom of the forend and having a vertical aperture shaped to receive a pivot holder;
the pivot holder shaped to slidingly move vertically within the vertical aperture in the firearm forend interface;
two pawls pivotally coupled to each other and to the pivot holder via a pivot pin;
a sling stud locking mechanism threadingly coupled to the pivot holder and configured to, via rotation of the sling stud locking mechanism, cause the 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.

11. The firearm assembly of claim 10 , wherein:
at least one of the two pawls includes a pawl detent at a first radius from the pivot pin;
a detent is arranged at least partially within a vertical aperture in the pivot holder;
a biasing component is arranged within the vertical aperture and below the detent, the biasing component configured to apply a bias to a bottom of the detent.

12. The firearm assembly of claim 11 , wherein when the locking mechanism is rotated in a first direction, the pivot holder, detent, and pivot pin move upward, and via interaction of a top of the detent and an irregular bottom surface of at least one of the pawls, both pawls are forced upward and tend to pivot outward toward an open position.

13. The firearm assembly of claim 10 , wherein:
at least one of the two pawls includes a pawl detent at a first radius from the pivot pin;
a detent is arranged at least partially within a vertical aperture in the pivot holder;
a biasing component is arranged within the vertical aperture and below the detent, the biasing component configured to apply a bias to a bottom of the detent.

14. The firearm assembly of claim 13 , wherein when the locking mechanism is rotated in a first direction, the pivot holder, detent, and pivot pin move upward, and via interaction of a top of the detent and an irregular bottom surface of at least one of the pawls, both pawls are forced upward and tend to pivot outward toward an open position.

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

16. The firearm assembly of claim 10 , wherein one or both of the pawls includes an irregular bottom surface.

17. The firearm assembly of claim 16 , wherein the irregular bottom surface includes a pawl detent and a pawl groove.

18. The firearm assembly of claim 17 , 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.
