Abstract
An elastic retention ring for the combustible casing of a piece of ammunition with respect to a base, the ring including two concentric substantially ring-shaped portions, one internal the other one external. The portions are linked by radial arms, and are continuous or not and have different diameters. The external portion incorporates at least one plane part and the radial arms form an angle with respect to the plane of plane part.
Claims10
An elastic retention ring for use with a combustible casing of a piece of ammunition that is held in place by a base, the elastic retention ring comprising:
- an internal substantially ring-shaped portion;
- an external substantially ring-shaped portion, concentric with the internal substantially ring-shaped portion and having a diameter larger than a diameter of the internal substantially ring-shaped portion;
- and
- a plurality of elastic radial arms that link the external substantially ring-shaped portion to the internal substantially ring-shaped portion,
- wherein the external substantially ring-shaped portion has at least one planar portion contacting a bottom surface of the casing, and the internal substantially ring-shaped portion extending in a plane parallel to the bottom surface of the casing and disposed above the at least one planar portion of the external substantially ring-shaped portion, with the plurality of elastic radial arms connecting the planar portion of the internal substantially ring-shaped portion to the planar portion of the external substantially ring-shaped portion.

- an internal substantially ring-shaped portion;
- a discontinuous external substantially ring-shaped portion, concentric with the internal substantially ring-shaped portion and having a combined diameter larger than a diameter of the internal substantially ring-shaped portion;
- and
- a plurality of elastic radial arms that link the discontinuous external substantially ring-shaped portion to the internal substantially ring-shaped portion,
- wherein the discontinuous external substantially ring-shaped portion has at least one planar portion contacting a bottom surface of the casing, and the internal substantially ring-shaped portion extends in a plane parallel to the bottom surface of the casing and disposed above the at least one planar portion of the external substantially ring-shaped portion, with the plurality of elastic radial arms connecting the planar portion of the internal substantially ring-shaped portion to the planar portion of the discontinuous external substantially ring-shaped portion.
