Foldable stock assembly
A folding stock assembly for a firearm includes a butt stock portion; a receiver interface portion; and a bidirectional hinge assembly configured to allow the butt stock portion to bidirectionally pivot with respect to the receiver interface portion.
1. A folding stock assembly for a firearm comprising:
a butt stock portion;
a receiver interface portion; and
a bidirectional hinge assembly including a coupler assembly, a first hinge assembly pivotally coupled to the coupler assembly, and a second hinge assembly pivotally coupled to the coupler assembly, the bidirectional hinge assembly configured to allow the butt stock portion to bidirectionally pivot with respect to the receiver interface portion from a first folded position on a first side of the firearm to a second folded position on a second side of the firearm without disconnecting either the first hinge assembly or the second hinge assembly from the coupler assembly.
2. The folding stock assembly of claim 1 wherein the butt stock portion is configured to allow for a length of pull adjustment.
3. The folding stock assembly of claim 1 wherein the butt stock portion is configured to allow for a cheek weld adjustment.
4. The folding stock assembly of claim 1 wherein the bidirectional hinge assembly includes:
a first latch assembly configured to releasably lock the first hinge assembly in a non-folded position;
and
a second latch assembly configured to releasably lock the second hinge assembly in the non-folded position.
5. The folding stock assembly of claim 4 wherein the
coupler assembly is configured to pivotally couple the first hinge assembly and the second hinge assembly.
6. The folding stock assembly of claim 1 further comprising:
a first catch assembly configured to releasably hold the butt stock portion in the first folded position; and
a second catch assembly configured to releasably hold the butt stock portion in the second folded position.
7. The folding stock assembly of claim 1 wherein the butt stock portion is a synthetic butt stock portion.
8. A folding stock assembly for a firearm comprising:
a synthetic butt stock portion;
a receiver interface portion; and
a bidirectional hinge assembly configured to allow the butt stock portion to bidirectionally pivot with respect to the receiver interface portion, wherein the bidirectional hinge assembly includes:
a coupler assembly;
a first hinge assembly pivotally coupled to the coupler assembly, the first hinge assembly configured to allow the bidirectional hinge assembly to pivot, about a first pivot point, between an extended position and a first folded position on a first side of the firearm, and
a second hinge assembly pivotally coupled to the coupler assembly, the second hinge assembly configured to allow the bidirectional hinge assembly to pivot, about a second pivot point offset from the first pivot point, between the extended position and a second folded position on a second side of the firearm, and
wherein the butt stock portion bidirectionally pivots with respect to the receiver interface portion from the first folded position to the second folded position without disconnecting either the first hinge assembly or the second hinge assembly from the coupler assembly.
9. The folding stock assembly of claim 8 wherein the bidirectional hinge assembly further includes:
a first latch assembly configured to releasably lock the first hinge assembly in a non-folded position; and
a second latch assembly configured to releasably lock the second hinge assembly in the non-folded position.
10. The folding stock assembly of claim 9 wherein the
coupler assembly is configured to pivotally couple the first hinge assembly and the second hinge assembly.
11. The folding stock assembly of claim 8 wherein the butt stock portion is configured to allow for a length of pull adjustment.
12. The folding stock assembly of claim 8 wherein the butt stock portion is configured to allow for a cheek weld adjustment.
13. The folding stock assembly of claim 8 further comprising;
a first catch assembly configured to releasably hold the butt stock portion in the first folded position; and
a second catch assembly configured to releasably hold the butt stock portion in the second folded position.
14. A firearm comprising:
a barrel assembly;
a receiver assembly; and
a folding stock assembly including:
a butt stock portion,
a receiver interface portion configured to engage the receiver assembly, and
a bidirectional hinge assembly including a coupler assembly, a first hinge assembly pivotally to the coupler assembly, and a second hinge assembly pivotally coupled to the coupler assembly, the bidirectional hinge assembly configured to allow the butt stock portion to bidirectionally pivot with respect to the receiver interface portion from a first folded position on a first side of the firearm to a second folded position on a second side of the firearm without disconnecting either the first hinge assembly or the second hinge assembly from the coupler assembly.
15. The firearm of claim 14 wherein the butt stock portion is configured to allow for a length of pull adjustment.
16. The firearm of claim 14 wherein the butt stock portion is configured to allow for a cheek weld adjustment.
17. The firearm of claim 14 wherein the bidirectional hinge assembly includes:
a first latch assembly configured to releasably lock the first hinge assembly in a non-folded position;
and
a second latch assembly configured to releasably lock the second hinge assembly in the non-folded position.
18. The firearm of claim 17 wherein the
coupler assembly is configured to pivotally couple the first hinge assembly and the second hinge assembly.
19. The firearm of claim 14 further comprising:
a first catch assembly configured to releasably hold the butt stock portion in the first, folded position; and
a second catch assembly configured to releasably hold the butt stock portion in the second folded position.
20. The firearm of claim 14 wherein the butt stock portion is a synthetic butt stock portion.
21. The firearm of claim 14 wherein the receiver assembly is a bolt action receiver assembly.
22. The firearm of claim 14 wherein the receiver assembly is a pump action receiver assembly.
23. The firearm of claim 14 wherein the receiver assembly is a semi-automatic/fully automatic receiver assembly.
