Bipod device for use with a firearm
Bipods bipods and mounting devices for attaching to and supporting firearms, more specifically, bipods which allow independent tension-adjustable movement around two axes. For example, the bipod assembly can be tension-adjusted with a first cam lock for cant movement and can be tension-adjusted with a second cam lock for pivotal movement. Accordingly, independently tension-adjustable and lockable pivot and cam adjustments are provided by this bipod assembly.
1. A bipod assembly for use with a firearm, the bipod assembly comprising:
an attachment assembly releasably engageable with the swivel stud of a firearm;
an adjustment assembly coupled to the attachment assembly, the adjustment assembly including a cant bushing extending at least partially through a pivot bushing, wherein the cant bushing allows movement of the bipod assembly about a first axis and the pivot bushing allows movement of the bipod assembly about a second axis;
a pair of legs coupled to the adjustment assembly; and
a pair of feet coupled to distal ends of the leg extensions, wherein the feet are removeably coupled to the leg extensions.
2. The bipod assembly of claim 1 wherein the attachment assembly includes a first portion and a second portion, the first portion has a protrusion and the second portion has a opposed protrusion, wherein the protrusions are configured to releasably retain the swivel stud.
3. The bipod assembly of claim 1 wherein the attachment assembly includes a threaded shaft configured to receive a locking washer thereon.
4. A bipod assembly for use with a firearm, the bipod assembly comprising:
an attachment assembly releasably engageable with the swivel stud of a firearm;
an adjustment assembly coupled to the attachment assembly, the adjustment assembly including a cant bushing and a pivot bushing, wherein the cant bushing allows movement of the bipod assembly about a first axis and the pivot bushing allows movement of the bipod assembly about a second axis, and wherein the adjustment assembly further includes a first locking cam that rotates about the first axis to stop movement about the first axis;
a pair of legs coupled to the adjustment assembly; and
a pair of feet coupled to distal ends of the leg extensions, wherein the feet are removeably coupled to the leg extensions.
5. The bipod assembly of claim 4 wherein the adjustment assembly further includes a second locking cam to stop movement about the second axis.
6. The bipod assembly of claim 1 further comprising a stock mount bracket for reciprocally mating adjacent the stock of the firearm.
7. The bipod assembly of claim 6 wherein the stock mount bracket further includes an aperture for receiving the attachment assembly.
8. The bipod assembly of claim 1 wherein the pivot bushing further includes sleeves removeably coupled to protrusions, wherein the sleeves releasably retain the leg extensions.
9. The bipod assembly of claim 8 wherein the sleeves further include a compression spring outwardly biasing the leg extensions to an open position.
10. The bipod assembly of claim 1 wherein the feet are removable from the leg extensions without a tool.
11. A bipod assembly for supporting a firearm having a firearm longitudinal axis, a stock portion, and a connector, the bipod assembly comprising:
a stock mount bracket configured to contact the stock portion;
an attachment portion carried by the stock mount bracket, wherein the attachment portion is configured to releasably engage the connector of the firearm; and
an adjustment portion carried by the stock mount bracket, the adjustment portion comprising
a cant bushing rotatably coupled to the stock mount bracket, the cant bushing having a first portion with a first longitudinal axis configured to be generally parallel to the firearm longitudinal axis, and a second portion extending away from the first portion in a direction generally perpendicular to the first longitudinal axis, and wherein the cant bushing is configured to rotate the firearm about the first longitudinal axis; and
a pivot bushing rotatably coupled to the cant bushing, wherein the pivot bushing includes an opening that rotatably receives the second portion of the cant bushing.
12. The bipod assembly of claim 11 wherein the first portion of the cant bushing includes a generally tubular body having an aperture extending therethrough configured to receive a pivot pin that is pivotally coupled to the stock mount bracket.
13. The bipod assembly of claim 12 wherein the second portion of the cant bushing has a generally cylindrical shape.
14. The bipod assembly of claim 12 wherein the cant bushing further comprises a first protrusion opposite a second protrusion, the first and second protrusions extending away from an exterior surface of the tubular body, wherein the first and second protrusions are configured to contact the stock mount bracket to at least partially limit the rotation of the stock mount bracket with reference to the cant bushing.
15. The bipod assembly of claim 11 wherein the pivot bushing includes a stop member partially extending into the opening, and wherein the second portion of the cant bushing includes a notched portion configured to contact the stop member to at least partially limit the rotation of the cant bushing with reference to the pivot bushing.
16. The bipod assembly of claim 11 wherein the adjustment assembly further comprises a first locking cam configured to restrict rotation of the stock mount bracket about the cant bushing.
17. The bipod assembly of claim 11 wherein the adjustment assembly further comprises a second locking cam configured to restrict rotation of the cant bushing with reference to the pivot bushing.
18. The bipod assembly of claim 11 wherein the attachment portion comprises a first arm opposite a second arm, the first arm having a first protrusion and the second arm having a second protrusion opposite the first protrusion, and wherein the first and second protrusions are configured to releasably engage the connector.
19. The bipod assembly of claim 11 wherein the adjustment portion comprises a shaft operably coupled to a tightening member, and wherein the stock mount bracket includes an aperture configured to receive at least partially receive the adjustment portion, and wherein movement of the tightening member on the shaft moves the attachment portion through the aperture.
20. The bipod assembly of claim 11 , further comprising a first leg extending from the adjustment assembly and a second leg extending from the adjustment assembly.
