Retractable bipod assembly for firearm

1. A retractable bipod assembly comprising:

a pair of leg assemblies adapted to support a firearm dining shooting thereof;

a housing adapted to be secured to a front portion of the firearm for pivotally mounting the leg assemblies between a folded up, storage position and folded down, support position; and

a coupling arrangement defined by gear teeth between the leg assemblies wherein the leg assemblies are in direct driving engagement and in continuous contact with one another enabling pivotal movement of one of the leg assemblies to automatically cause simultaneous pivot movement of the other of the leg assemblies,

wherein the housing includes a pair of vertically extending side walls, each of the side walls being formed with an outwardly facing leg-receiving pocket defined by a first wall extending inwardly and downwardly from he side wall and connected to a second wall extending downwardly and outwardly therefrom, the first walls converging towards each other and the second walls diverging from each other, the pockets holding the leg assemblies at angular orientations relative to the side walls, the leg assemblies having lower portions engageable and disengageable with the first walls between the folded up, storage position, and the folded down, support position, and the gear teeth lying adjacent the second walls.

2. The bipod assembly of claim 1 , wherein the housing is structured to maintain a constant spaced apart orientation of the leg assemblies between the storage and support positions.

3. The bipod assembly of claim 1 , wherein the housing includes a mounting channel adapted to be matingly received on a front portion of the firearm.

4. The biped assembly of claim 1 , wherein the housing includes a latching arrangement pivotally mounted thereto for selectively locking and unlocking the leg assemblies in the storage and support positions,

wherein upper portions of the leg assemblies have heads constructed with smooth facing inner surfaces provided on peripheral portions thereof with the gear teeth and the latching arrangement includes a latch member positioned between the facing inner surfaces and engageable with spaced apart notches separately spaced from and lying radially inwardly from the gear teeth on the smooth facing inner surfaces of the heads.

5. The biped assembly of claim 1 , wherein the coupling arrangement includes a meshing relationship between the leg assemblies.

6. The biped assembly of claim 1 , wherein the leg assemblies are movable on the housing about independent pivot axes which intersect each other.

7. A retractable biped assembly for a firearm comprising:

a pair of leg assemblies for supporting a front portion of a firearm during shooting thereof: and

a housing secured on the front portion of the firearm for pivotally mounting the leg assemblies between a folded up, storage position and a folded down, support position, and for maintaining a constant spaced apart orientation of the leg assemblies,

wherein the leg assemblies are connected together by gear teeth in meshing engagement, and

wherein the housing includes a pair of vertically extending side walls interconnected at an upper end by a mounting portion fixed and formed therein, each of the side walls being formed at a rearward end thereof with an outwardly facing leg-receiving pocket defined by a first wall extending inwardly and downwardly from the side wall, and connected to a second wall extending downwardly and outwardly therefrom, the first walls converging towards each other and forming part of the mounting portion, and the second walls diverging from each other and forming part of a closed lower end of the housing, the pockets holding the leg assemblies at angular orientations relative to the side walls, the leg assemblies having lower portions engageable and disengageable with the first walls between the folded up, storage position and the folded down, support portion, and the gear teeth lying adjacent the second walls.

8. The biped assembly of claim 7 , wherein each of the leg assemblies has an inner leg slidably mounted within an outer leg.

9. The biped assembly of claim 8 , wherein each of the leg assemblies include a clamping arrangement for holding the inner leg in a desired position relative to the outer leg.

10. The bipod assembly of claim 8 , wherein the outer legs have rounded heads provided with the gear teeth that are interconnected together in driving relationship.

11. The bipod assembly of claim 10 , wherein the gear teeth on each outer leg lie adjacent the downwardly and outwardly extending wall.

12. The bipod assembly of claim 7 , wherein the housing includes a mounting channel which is slidably mounted on a rail of a forend mounting arrangement positioned on the front portion of the firearm.

13. The bipod assembly of claim 10 , wherein the housing includes a latching arrangement pivotally mounted about a horizontal axis between the side walls for selectively locking and unlocking the leg assemblies in the storage and support positions, and

wherein the heads are constructed with smooth facing inner surfaces provided on peripheral portions thereof with the gear teeth, and the latching arrangement includes a latch member positioned between the facing inner surfaces and engageable with a spaced notches separately spaced from and lying radially inwardly from the gear teeth on the smooth facing inner surfaces of the heads.

14. A retractable bipod assembly for a firearm comprising:

a pair of leg assemblies for supporting a front portion of a firearm; and

a housing attached on the front portion of the firearm for pivotally mounting the leg assemblies between a folded up, storage position and a folded down, support position, and for maintaining a constant spaced apart angular orientation of the leg assemblies,

wherein the leg assemblies are constructed with cooperating gear teeth that provide a direct driving connection with each other such that engagement and pivotal movement of one of the leg assemblies automatically translates simultaneous pivotal movement to the other of the leg assemblies, and

wherein upper portions of the leg assemblies have heads constructed with smooth facing inner surfaces provided on peripheral portions thereof with the gear teeth, and the housing further includes a latching arrangement having a spring-biased lever having an outer end provided with a finger-engageable portion extending forwardly from the housing, and an inner end defining a latch member positioned between the smooth facing inner surfaces and engageable with spaced apart notches separately spaced from and lying radially inwardly from the gear teeth on the smooth facing inner surfaces of the heads.
