Abstract
Devices, and methods of extending legs from vertical fore grip handles on firearms, such as rifles, to different height positions. The vertical fore grip can include expandable bipod legs. The legs can be individually extended to different lengths by moving telescoping rod members in leg housings from retracted positions to extended positions. A lever switch can allow for the legs to be locked into the different extended positions, and depressing the switch can allow for the legs to go back to the retracted positions. Anti-rotation pins and slots can prevent the telescoping members from rotating relative to the legs.
Claims21
A firearm fore grip with extendable legs, comprising:
- an elongated handle with a generally elongated cylindrical housing, having a top end and a bottom end, the top end having a mount for attaching the upper end to a firearm having picatinny rails underneath the firearm, the mount having a pair of parallel rail clamps with a longitudinal space therebetween, the rail clamps for clamping to portions of the picatinny rails under the firearm;
- a pair of legs, each of the legs having an upper end and a bottom end, each of the legs having a longitudinal axis;
- an activation switch on the cylindrical housing which when activated causes the pair of legs to move from a retracted position with the legs substantially within the cylindrical housing, to release to an expansion position where substantially much of the legs protrude out beneath the cylindrical housing;
- and
- each of the legs is independently adjustable in length to different height positions,
- wherein the elongated handle being used as a fore grip that is adaptable to be gripped by a user when the pair of the legs are in the retracted position, and wherein the legs form a bipod when the legs are in the expansion position.

A bipod support stand for firearms with extendable legs comprising:
- an elongated cylindrical housing adaptable for being used as a fore grip for a firearm, the housing having an upper mount for attaching underneath the firearm, the housing having a bottom end with an opening therethrough;
- a pair of telescoping legs having upper ends and lower ends, the pair of legs having a retracted position that substantially fits inside of the housing, wherein the legs in the retracted position allows the housing to be used as the fore grip for the firearm, the legs having an extended position that forms an angled bipod legs configuration that are adaptable to support the firearm over a ground surface, wherein the telescoping legs are individually height adjusted over different support surfaces, wherein each of the bipod legs include:
- telescoping members;
- and
- an access slot for allowing a user to grip a portion of the telescoping members in order to extend the telescoping members to the different lengths.
