Folding gunstock
View Patent ↗A folding stock assembly for firearms such as rifles and shotguns. The stock is made of metal rod that has been bent to form laterally spaced left and right elongated arm members that have rear ends connected to the top end of a U-shaped shoulder rest portion. The front end of the respective elongated arm members are pivotally connected to the rear end of a neck portion extending rearwardly from the upper end of the handgrip. There is structure in the interior of the end cap for locking the elongated arm members in either its static storage position or its rearward functional deployed position.
1. A folding stock assembly for a firearm, comprising;
an elongated stock having laterally spaced left and right elongated arm members each having a front end and a rear end;
said front end of said left elongated arm member having a left front end member secured thereto, said left front end member having a left shaft member extending inwardly therefrom, said left shaft having a front end having a left disc rigidly secured thereto, and said left disc having an outer surface and an inner surface;
said front end of said right elongated arm member having a right front end member secured thereto, said right front end member having a right shaft member extending inwardly therefrom, said right shaft member having a front end having a right disc rigidly secured thereto, and said right disc having an outer surface and an inner surface;
a vertically oriented shoulder rest portion having laterally spaced top ends that are connected to the respective rear ends of said respective left and right elongated arm members;
pivot means connected to said respective front ends of said elongated left and right arm members that allow said elongated stock to pivot from a static forward stored position to a functional deployed position;
a handgrip of a firearm having a neck portion extending rearwardly therefrom;
a tubular member having a rear end extending rearwardly from said neck portion, wherein a pair of diametrically opposed locking channels are formed in said tubular member adjacent said rear end, wherein each locking channel is formed so as to accept one of the left shaft member or the right shaft member.
2. The folding gunstock of claim 1 , wherein said left and right elongated arm members and said shoulder rest portion are integrally formed.
3. The folding gunstock of claim 2 , wherein said left and right elongated arm members and said shoulder rest portion are made of metal rod.
4. The folding gunstock of claim 1 , in combination with a firearm having a handgrip connected to the rear end of the receiver of the firearm; said handgrip having a neck portion extending rearwardly from the top end of the handgrip.
5. The folding gunstock of claim 1 , wherein said front end of said left elongated arm member has a left front end member secured thereto;
said left front end member having a left shaft member extending inwardly therefrom; said left shaft having a front end having a left disc rigidly secured thereto; said left disc having an outer surface and an inner surface;
said right front end member having a right shaft member extending inwardly therefrom; said right shaft member having a front end having a right disc rigidly secured thereto; said right disc having an outer surface and an inner surface.
6. The folding gunstock of claim 5 , further comprising a handgrip of a firearm having a neck portion extending rearwardly therefrom; a tubular member having a rear end extends rearwardly from said neck portion; and a pair of diametrically opposed locking channels are formed in said tubular member adjacent said rear end.
7. The folding gunstock of claim 1 , further comprising a tubular end cap open at its front end and having a rear wall closing said rear end; a pair of diametrically opposed primary horizontal apertures are formed in said cap that align with said diametrically opposed locking channels when said cap is telescoped over said rear end of said tubular member; said left shaft member and said right shaft member are inserted into their respective primary apertures and their respective locking channel.
8. The folding gunstock of claim 7 , wherein said left and right front end members are disc-shaped.
9. The folding gunstock of claim 7 , further comprising a knob extending rearwardly from said rear wall of said cap and there is a sling-attachment aperture extending transversely through said knob.
10. The folding gunstock of claim 7 , further comprising a raised boss member on said outer surface of said left and right disc and they are removably interlocked with structure in said cap to releasably lock said elongated stock in either its static forward stored position or in its rearward functional deployed position.
11. The folding gunstock of claim 10 , wherein said left and right disc have a raised shoulder on their inner surfaces having a pair of stops that limit the number of degrees of rotation of said left and right shaft members.
