Abstract

A firearm with movable cheek riser is a rifle stock having a stock body having a facility for receiving a rifle action and a rear extending portion, a stock butt portion telescopically connected to the rear extending portion, the butt portion being movable between a retracted position and an extended position, a cheek riser having a rear portion connected to the butt portion and a front portion connected to the stock body, and the cheek riser being movable between an elevated position and a lower position. The cheek riser may be pivotally connected to the butt portion. The cheek riser may include a downwardly-depending post received in a post bore defined in the stock body, wherein the post is curved such that a pivoting motion of the stock is facilitated. The invention may be a rifle including the rifle stock receiving a barreled rifle action.

Claims

1. A rifle stock having a movable cheek riser comprising:

a stock body having a facility for receiving a rifle action;

the stock body having a rear extending portion;

a stock butt portion telescopically connected to the rear extending portion;

the butt portion movable between a retracted position and an extended position;

a cheek riser having a rear portion pivotally connected to the butt portion, and a front portion directly connected to the stock body; and

the cheek riser movable between an elevated position and a lowered position.

2. The rifle stock of claim 1 wherein the cheek riser includes a downwardly-depending post received in a post bore defined in the stock body, and wherein the post is curved, such that a pivoting motion of the cheek riser is facilitated.

3. The rifle stock of claim 2 wherein the cheek riser includes a pivot element constrained by the butt position, and wherein the post is curved on a radius centered on the pivot element, such that the post may freely move within the bore when the riser pivots about the pivot element.

4. The rifle stock of claim 2 wherein the post bore is curved to closely receive the post.

5. The rifle stock of claim 1 wherein the butt portion defines a channel, and wherein the cheek riser includes a pivot element received in the channel, such that the butt portion may be telescopically moved with respect to the stock body while the cheek riser is secured in position.

6. The rifle stock of claim 1 wherein the cheek riser is connected to the stock body in a manner constraining axial motion of the riser, and is connected to the butt portion in a manner constraining vertical motion of the riser.

7. The rifle stock of claim 1 wherein the stock body defines a plurality of upwardly-open post bores, and wherein the cheek riser includes a plurality of downwardly-depending posts, each closely received in a corresponding post bore.

8. The rifle stock of claim 7 wherein two of the posts have contoured surfaces having engagement surfaces, and wherein a latch element is received within a latch bore in the stock body, and latch bore being positioned between the bores associated with the two of the posts, such that the latch may selectably engage the engagement surfaces to retain the riser in a selected position.

9. The rifle stock of claim 8 wherein the contoured surfaces on each post include a repeating pattern of engagement surfaces, each corresponding to a selected position of the riser.

10. The rifle stock of claim 9 wherein the contoured surfaces of one post are spaced at a first pitch, and the contoured surfaces of the other post are spaced at a different second pitch.

11. The rifle stock of claim 10 wherein the pitch of the contoured surfaces is proportional to the distance of the contoured surfaces from a selected pivot point on the riser.

12. The rifle stock of claim 1 wherein the riser is an elongated body defining an inward facing channel defined between opposed side walls.

13. The rifle stock of claim 12 wherein the riser includes opposed pivot bumps protruding from opposed rear portions of inward facing faces of the sidewalls.

14. The rifle stock of claim 12 wherein the riser includes a post depending downward from a forward portion of the riser, medial between the sidewalls.

15. The rifle stock of claim 14 wherein including a plurality of downwardly depending posts arranged in a common vertical plane medial between the sidewalls.

16. The rifle stock of claim 12 wherein the butt portion includes a latch operable to engage the stock body in a plurality of different extension positions, and further defines a pair of opposed elongated channels, each receiving one of the pivot bumps.

17. A rifle comprising the rifle stock of claim 1 receiving a barreled rifle action.
