Rifle stock with recoil absorption facility
A rifle stock has an elongated body with a forward end and a butt end. The upper and lower edges of the stock are solid and continuous from front to rear. A slot generally parallel to the butt plate is formed adjacent to the butt plate to allow limited flexing in response to recoil. The stock may be formed as a hollow shell with opposed side walls, with slots to find in each sidewall. Several parallel slots may be defined in each sidewall. The slots may be occupied by elastomeric elements.
1. A rifle stock comprising: a hollow stock body having a longitudinal axis and a butt end defining a butt plane; a forward end opposite the butt end; an upper edge extending between the butt end and the forward end; a lower edge extending between the butt end and the forward end; and opposed sidewalls having a thickness extending from the upper edge to the lower edge and from the butt end to the forward end and together enclosing an inner volume opened at the butt end of said hollow stock body; each sidewall including an elongated opening formed between the upper and lower edges adjacent to the butt end, the elongated opening having upper and lower ends disposed on a line substantially parallel to the butt plane and extending the majority of a butt end height measured along said line.
2. The stock of claim 1 wherein each opening extends through the thickness of the sidewall to open on the inner volume.
3. The stock of claim 1 further comprising an array of adjacent elongated openings formed in the opposed sidewalls and defining elongated spans of stock material extending between the upper and lower edges, wherein the openings formed in each sidewall adjacent the butt end are the first openings in each array.
4. The stock of claim 3 , wherein the openings are curved arcs that are concave toward the forward end of the stock.
5. The stock of claim 3 wherein the openings diminish in length from the butt end toward the forward end.
6. The stock of claim 1 , wherein each sidewall includes a butt end span continuous between the upper and lower edges.
7. A firearm assembly comprising:
a hollow rifle stock body defining a major axis; the stock body having a butt end, a forward end opposed to the butt end, upper and lower edges extending between the butt end and the forward end, and sidewalls extending from the butt end to the forward end between the upper and lower edges to enclose an inner volume therebetween, the butt end having a height measured between the upper and lower edges, and defining a butt plane substantially perpendicular to the major axis; and the stock body having an array of elongated slots formed in the sidewalls and opening on the inner volume, each slot being generally parallel to the butt plane, the array of slots being arranged side-by-side along the major axis.
8. The firearm assembly of claim 7 wherein at least one of the slots has a length greater than one half of the butt end height.
9. The firearm assembly of claim 7 wherein the slots are occupied by an elastomeric material.
10. A rifle stock comprising: an elongated hollow body having a forward end and a butt end; an upper edge of the body extending between the forward end and the butt end; a lower edge of the body extending between the forward end and the butt end; opposed sidewalls extending from the butt end to the forward end between the upper and lower edges to enclose an inner volume of the hollow body; and an elongated flexible span adjacent the butt end and solidly joined to the upper and lower edges of the body at the upper and lower ends of the span, a middle portion of the elongated span being suspended between said upper and lower ends and being tapered so as to be narrower at an intermediate portion thereof, wherein each sidewall defines an array of elongated openings, the openings progressively decreasing in length based on their distance from the butt end.
11. A rifle stock comprising: a hollow stock body having a longitudinal axis and a butt end defining a butt plane; a forward end opposite the butt end; an upper edge extending between the butt end and the forward end; a lower edge extending between the butt end and the forward end; opposed sidewalls having a thickness extending from the upper edge to the lower edge bounded by the butt end and the forward end; and an elongated opening formed in each sidewall adjacent to the butt end and having upper and lower ends thereof disposed on a line substantially parallel to a plane defined by the butt end, wherein each elongated opening is occupied by an elastomeric insert sized to closely fit within each elongated opening.
12. The stock of claim 11 wherein each opening extends through the thickness of the sidewall.
13. The stock of claim 11 , wherein each elongated opening adjacent to the butt end is a first of an array of adjacent elongated openings formed in the opposed sidewalls and separating elongated spans of stock material extending between the upper and lower edges of the stock, the array extending forward from the butt end along the longitudinal axis.
14. The stock of claim 13 , wherein at least some of the openings are curved arcs that are concave toward the forward end of the stock.
15. The stock of claim 13 wherein the openings diminish in length from the butt end toward the forward end.
