Bipod for light-weight machine gun
A bipod for a light-weight machine gun is disclosed. The bipod has tubular telescoping legs with large ground-engaging feet that may be extended and retracted to discreet locking positions. The bipod has a spring-based system that allows a user to pivot the bipod legs about cylinder-in-a-cylinder pivot pins, either towards or away from the barrel muzzle with one hand, thus giving 180 degrees of travel. The bipod is attachable to a machine gun with a round yoke using a stepped screw and compression spring that assures yoke remains tightly secured to body, but rotatable for traversing, during extended use.
1. A bipod for use with a firearm, said bipod comprising:
(a) a hollow body with a hole formed therein;
(b) a pair of legs pivotally attached to said hollow body, said legs having a stored position and a deployed position;
(c) a ring-shaped yoke formed to mount a firearm barrel, said yoke having a threaded hole formed therein;
(d) a stepped screw dimensioned to fit through said hole in said hollow body and be threadably received into said threaded hole in said yoke;
(e) a compression spring held between said hollow body and said stepped screw, said compression spring being placed over said stepped screw, said stepped screw compressing said compression spring when threaded into said hole in said yoke through said hole in said hollow body; and
(f) urging means carried by said body and connecting said legs so that when a first leg of said pair of legs is pivoted with respect to said body between said stored and said deployed positions, said urging means pivots said second leg with said first leg.
2. The bipod as recited in claim 1 , wherein said legs have ground-engaging feet, said feet having a surface area at least 11 square centimeters.
3. The bipod as recited in claim 1 , wherein said pair of legs is pivotally attached to said hollow body with a pivot pin, said pivot pin including a first cylinder and a second cylinder, said first cylinder being inside said second cylinder.
4. The bipod as recited in claim 3 , wherein said first cylinder is a coil.
5. The bipod as recited in claim 3 , wherein said second cylinder has a slit formed therein.
6. The bipod as recited in claim 3 , wherein said first and said second cylinders have slits and said slit in said first cylinder being oriented approximately 180° from said slit in said second cylinder.
7. The bipod as recited in claim 1 , further comprising a thread locking compound to retain said spring in said yoke.
8. A bipod for use with a firearm, said bipod comprising:
(c) a hollow body with a hole formed therein;
(b) a ring-shaped yoke pivotally carried by said body and formed to mount to a firearm barrel, said yoke having a threaded hole formed therein;
(c) a first leg having a first end and an opposing second end;
(d) a second leg having a first end and a second end, said first and said second legs having a stored position and a deployed position;
(e) means carried by said body for connecting said first leg to said second leg so that pivoting said first leg pivots said second leg;
(f) a stepped screw dimensioned to fit through said hole in said hollow body and be threadably received by said threaded hole in said yoke;
(g) a compression spring held between said hollow body and said stepped screw, said compression spring being placed over said stepped screw, said stepped screw compressing said compression spring when threaded into said hole in said yoke through said hole in said hollow body; and
(g) urging means carried by said body and in operational connection with said legs so that when a first leg is pivoted with respect to said body from said stored to said deployed positions, said urging means splays said first and said second legs.
9. The bipod as recited in claim 8 , wherein said legs have ground-engaging feet, said feet having a surface area at least 11 square centimeters.
10. The bipod as recited in claim 8 , wherein said pair of legs is pivotally attached to said hollow body with a pivot pin, said pivot pin including a first cylinder and a second cylinder, said first cylinder being inside said second cylinder.
11. The bipod as recited in claim 10 , wherein said first cylinder is a coil.
12. The bipod as recited in claim 10 , wherein said second cylinder has a slit formed therein.
13. The bipod as recited in claim 10 , wherein said first and said second cylinders have slits and said slit in said first cylinder being oriented approximately 180° from said slit in said second cylinder.
