Abstract

An adjustable stock for a firearm includes a fixed body attachable to the firearm and a moveable body slideably connected to the fixed body. The moveable body defines a butt of the stock. A hole may be defined in one of the fixed body and the moveable body that has a first side opening and a second side opening disposed opposite the first side opening. A position selector is disposed in the hole and includes a first selector body and a second selector body. The first selector body includes a body portion shaped as a button having an engagement surface and a protrusion extending away from the body portion. The second selector body includes a body portion shaped as a button having an engagement surface and a protrusion extending away from the body portion. A biasing device is disposed between the first and second selector bodies to bias the first and second selector bodies apart and so that the engagement surface of the first selector body extends from the first side opening and the engagement surface of the second selector body extends from the second side opening. Further, a plurality of locating slots is defined in the other of the fixed body and the moveable body. At least one of the protrusions of the first and second selector bodies engage one of the plurality of locating slots to selectively fix the relative position of the moveable body to the fixed body.

Claims

1. An adjustable stock for a firearm, comprising:

a fixed body attachable to the firearm;

a moveable body slideably connected to the fixed body, the moveable body including a butt of the stock;

a hole defined in one of the fixed body and the moveable body, the hole having a first side opening and a second side opening disposed opposite the first side opening;

a plurality of locating slots defined in the other of the fixed body and the moveable body;

a position selector including;

a first selector body having a body portion shaped as a button having an engagement surface and a protrusion extending away from the body portion;

a second selector body having a body portion shaped as a button having an engagement surface and a protrusion extending away from the body portion;

a biasing device disposed between the first and second selector bodies to bias the first and second selector bodies apart, wherein the position selector is disposed in the hole, wherein the engagement surface of the first selector body extends from the first side opening and the engagement surface of the second selector body extends from the second side opening, wherein one of the protrusions of the first and second selector bodies engage one of the plurality of locating slots to selectively fix the relative position of the moveable body to the fixed body;

wherein the abutment surfaces of the first and second selector bodies are stepped, wherein when the engagement surfaces are fully pressed, the stepped abutment surfaces are brought into abutment.

2. The stock of claim 1, wherein the biasing device is a spring having a first end and a second end, wherein the first end abuts the first selector body and the second end abuts the second selector body.

3. The stock of claim 2, wherein the first selector body includes an orifice disposed in the abutment surface, wherein the orifice is shaped to receive the first end of the spring, wherein the second selector body includes an orifice disposed in the abutment surface, wherein the orifice is shaped to receive the second end of the spring.

4. The stock of claim 1, wherein the biasing device is an elastomeric polymer, having a first end and a second end, wherein the first end abuts the first selector body and the second end abuts the second selector body.

5. The stock of claim 4, wherein the first selector body includes an orifice disposed in the abutment surface, wherein the orifice is shaped to receive the first end of the elastomeric polymer, wherein the second selector body includes an orifice disposed in the abutment surface, wherein the orifice is shaped to receive the second end of the elastomeric polymer.

6. The stock of claim 1, wherein when the engagement surfaces are pressed, the one of the protrusions of the first and second selector bodies disengages from the one of the plurality of locating slots to permit the relative position of the moveable body to the fixed body to be changed.

7. The stock of claim 1, wherein when the engagement surfaces are pressed, the protrusions of the first and second selector bodies are fully disposed within the hole.

8. The stock of claim 1, wherein the hole is defined in the moveable body and the plurality of locating slots are defined in the fixed body.

9. The stock of claim 8, wherein the plurality of locating slots include a first and second array of locating slots disposed opposite each other about a sliding channel.

10. The stock of claim 8, wherein the sliding channel is sized to permit the moveable body to slide within said sliding channel to change the relative position of the moveable body to the fixed body.

11. An adjustable stock for a firearm, comprising:

a fixed body attachable to the firearm;

a moveable body slideably connected to the fixed body, the moveable body including a butt of the stock;

a hole defined in one of the fixed body and the moveable body, the hole having a first side opening and a second side opening disposed opposite the first side opening;

a plurality of locating slots defined in the other of the fixed body and the moveable body;

a position selector including;

a first selector body having a body portion shaped as a button having an engagement surface and a protrusion extending away from the body portion;

a second selector body having a body portion shaped as a button having an engagement surface and a protrusion extending away from the body portion; and

a biasing device disposed between the first and second selector bodies to bias the first and second selector bodies apart, wherein the position selector is disposed in the hole, wherein the engagement surface of the first selector body extends from the first side opening and the engagement surface of the second selector body extends from the second side opening, wherein one of the protrusions of the first and second selector bodies engage one of the plurality of locating slots to selectively fix the relative position of the moveable body to the fixed body,

wherein when the engagement surfaces are pressed, the protrusions of the first and second selector bodies are fully disposed within the hole, wherein the first selector body includes an abutment surface opposite the engagement surface and the second selector body includes an abutment surface opposite the engagement surface; and

wherein the abutment surfaces of the first and second selector bodies are stepped, wherein when the engagement surfaces are fully pressed, the stepped abutment surfaces are brought into abutment.

12. The stock of claim 11, wherein the biasing device has a first end and a second end, wherein the first end abuts the first selector body and the second end abuts the second selector body, wherein the first selector body includes an orifice disposed in the abutment surface, wherein the orifice is shaped to receive the first end of the biasing device, wherein the second selector body includes an orifice disposed in the abutment surface, wherein the orifice is shaped to receive the second end of the biasing device.

13. The stock of claim 12, wherein the biasing device is an elastomeric polymer.

14. The stock of claim 12, wherein the biasing device is a spring.

15. The stock of claim 11, wherein when the engagement surfaces are pressed, the one of the protrusions of the first and second selector bodies disengages from the one of the plurality of locating slots to permit the relative position of the moveable body to the fixed body to be changed.

16. The stock of claim 11, wherein the hole is defined in the moveable body and the plurality of locating slots are defined in the fixed body.

17. The stock of claim 16, wherein the plurality of locating slots include a first and second array of locating slots disposed opposite each other about a sliding channel, wherein the sliding channel is sized to permit the moveable body to slide within it to change the relative position of the moveable body to the fixed body.
