US12422209 - Firearm bipod

This disclosure describes systems, methods, and apparatus for a bipod having pivot and cant functionality built into a unified cant/pivot assembly, housing, and pivot block. Rotation of a locking knob under the housing can gradually increase or decrease friction of the cant and pivoting degrees of freedom. Sufficient loosening of the locking knob can allow a pivot block to be lifted from the housing and rotated 180°, and then retightened to lock in a given pivot position. Before this 180 rotation of the pivot block, the pivot block and hence the firearm is free to pivot up to 10°, or up to 20°, or up to 30°.

firearmbipodaccessory

The patent describes a bipod for firearms that incorporates a pivot and cant functionality within a single assembly, allowing for adjustable friction and locking of pivot positions. It features a deployment lock mechanism that secures the bipod legs in place and enables rotation from a deployed to a stowed position.

Claim 1

A bipod leg deployment assembly comprising: a bipod leg having a deployment lock biased away from a bipod housing into a locked state; a first length of the deployment lock comprising at least a first diameter, the first length being a tubular shape or a conical frustum, wherein the first length is biased away from the bipod housing with the deployment lock in the locked state; a first cutout in a leg assembly near a leg deployment pivot axis of the leg assembly, the first cutout shaped to interface with the first length of the deployment lock such that the leg assembly is unable to rotate when the deployment lock is in the locked state, and wherein the first cutout is curved; wherein the deployment lock is moveable toward the bipod housing into an unlocked state such that the first cutout and the first length of the deployment lock no longer interface; and wherein the leg assembly is rotatable from a deployed position toward a stowed position. a bipod leg having a deployment lock biased away from a bipod housing into a locked state; a first length of the deployment lock comprising at least a first diameter, the first length being a tubular shape or a conical frustum, wherein the first length is biased away from the bipod housing with the deployment lock in the locked state; a first cutout in a leg assembly near a leg deployment pivot axis of the leg assembly, the first cutout shaped to interface with the first length of the deployment lock such that the leg assembly is unable to rotate when the deployment lock is in the locked state, and wherein the first cutout is curved; wherein the deployment lock is moveable toward the bipod housing into an unlocked state such that the first cutout and the first length of the deployment lock no longer interface; and wherein the leg assembly is rotatable from a deployed position toward a stowed position.
