Firearm stock with cheek riser and methods

Abstract

A firearm stock system is described. The firearm stock system may comprise a stock, a firearm frame member positionally adjustable to the stock, a bottom plate disposed in connection with the stock, and a first rod rigidly connected with the bottom plate. The first rod axially may align to the bottom plate to the stock when the bottom plate is moved from a collapsed position to an expanded position or from an expanded position to a collapsed position The firearm stock may additionally comprise a second rod rigidly connected with the bottom plate and a guide block axially aligned with the second rod and a first spring axially aligned with one of the first rod or the second rod, the first spring configured to bias the bottom plate to the collapsed position.

We claim: 
     
         1 . A firearm stock system, comprising:
 a frame member, the frame member comprising a plurality of frame member bores;   a stock body that is configured to be positioned along the frame member, the stock comprising:
 a bottom plate disposed in connection with the stock body; 
 a first rod rigidly connected with the bottom plate; 
 a second rod rigidly connected with the bottom plate; 
 a guide block axially aligned with the second rod, wherein the guide block is configured to selectively guide the second rod into to one of the plurality of frame member bores as the bottom plate moves from an expanded position to a collapsed position; and 
 a internal skeleton that maintains movement of the first rod and the second rod perpendicular to a longitudinal axis of the frame member. 
   
     
     
         2 . The firearm stock system of  claim 1 , wherein the stock body further comprising a first spring axially aligned with one of the first rod or the second rod, the first spring configured to bias the bottom plate to the collapsed position. 
     
     
         3 . The firearm stock system of  claim 1 , further comprising:
 a cheek riser;   a riser mechanism attached to the cheek riser and configured to adjust the cheek riser from a first position to a second position; and   a button mechanism coupled to a pin and configured to actuate a movement of the riser mechanism;   
       wherein the rising mechanism includes a first aperture that engages the pin. 
     
     
         4 . The firearm stock system of  claim 3 , wherein the riser mechanism comprises a second aperture and a third aperture configured to engage the pin. 
     
     
         5 . The firearm stock system of  claim 4 , wherein the first aperture, the second aperture, and the third aperture further comprise an ovaloid cavity that engages the pin. 
     
     
         6 . The firearm stock system of  claim 5 , wherein the pin comprises a first set of wings configured to engage the ovaloid cavity disposed on the second aperture to secure the cheek riser in a first position, wherein the first position is different from a second position of the cheek riser when the pin engages the first aperture. 
     
     
         7 . The firearm stock system  claim 1 , further comprising a second spring axially aligned with another one of the first rod or the second rod, the second spring configured to bias the bottom plate to the collapsed position. 
     
     
         8 . A firearm stock system comprising:
 A stock body;   a cheek riser coupled to the stock body and adjustable between respective positions above the stock body, the check riser comprising:
 a riser mechanism disposed within the stock body, wherein the riser mechanism comprises a plurality of apertures configured to adjust the cheek riser from a first position of the respective positions to a second position of the respective positions; and 
 a button mechanism coupled to a pin, the pin configured to selectively engage the plurality of apertures of the riser mechanism when the button mechanism is in a first rest position, and the pin configured disengage the plurality of apertures of the riser mechanism when the button mechanism is in a second actuated position. 
   
     
     
         9 . The firearm stock system of  claim 8 , wherein the plurality of apertures comprise a first aperture and a second aperture configured to engage the pin. 
     
     
         10 . The firearm stock system of  claim 9 , wherein the first aperture and the second aperture further comprise an ovaloid cavity that engage the pin. 
     
     
         11 . The firearm stock system of  claim 10 , wherein the pin comprises a first set of wings configured to engage the ovaloid cavity disposed on the second aperture to secure the cheek riser in a first position, wherein the first position is different from a second position of the cheek riser when the pin engages the first aperture. 
     
     
         12 . The firearm stock system of  claim 11 , wherein the pin further comprises a second set of wings configured to limit a position of the button mechanism while the button mechanism is in the rest position. 
     
     
         13 . The firearm stock system of  claim 8 , further comprising:
 a stock;   a bottom plate disposed in connection with the stock;   a first rod rigidly connected with the bottom plate, the first rod axially aligning the bottom plate to the stock when the bottom plate is moved from a collapsed position to an expanded position or from an expanded position to a collapsed position;   a second rod rigidly connected with the bottom plate;   a guide block axially aligned with the second rod, wherein the guide block is configured to guide the second rod to a bore of a plurality of frame member bores as the bottom plate moves from the expanded position to the collapsed position; and   a first spring axially aligned with one of the first rod or the second rod, the first spring configured to bias the bottom plate to the collapsed position.   
     
     
         14 . The firearm stock system  claim 13 , further comprising a second spring axially aligned with another one of the first rod or the second rod, the second spring configured to bias the bottom plate to the collapsed position. 
     
     
         15 . The firearm stock system of  claim 8 , wherein the riser mechanism further comprises a set of deformable arms configured to move in a channel; and
 wherein the riser mechanism comprises a first deformable arm having a first deformable arm protrusion and a second deformable arm having a second deformable arm protrusion.   
     
     
         16 . The firearm stock system of  claim 15 , wherein the first deformable arm and the second deformable arm deform when the riser mechanism is moved in the channel from the first aperture position to the second aperture position and the first and second deformable arm protrusions interfere with channel side walls. 
     
     
         17 . The firearm stock system of  claim 16 , wherein the riser mechanism further comprises a key disposed between the first and second deformable arms, the key configured to allow for vertical adjustment of riser plate while limiting deformation of the deformable arms.
