Firearm bolt assembly
First Claim
Patent Images
1. For use in a firearm having a barrel and a locking element formed at the proximal end of the barrel, a bolt assembly comprising:
- a bolt carrier;
a bolt head;
a connecting device operatively coupling the bolt carrier and the bolt head;
an elastic sleeve mounted on the connecting device and having an expanded state and a compressed state, the elastic sleeve contacting the bolt carrier and the bolt head in the expanded state to thereby substantially prevent relative longitudinal movement between the bolt head and the bolt carrier;
whereby compression of the sleeve from the expanded state toward the compressed state permits relative longitudinal movement between the bolt head and the bolt carrier; and
means for damping vibrations of the elastic sleeve.

Abstract
An elastic sleeve having a longitudinal slit is positioned between a bolt head and bolt carrier. The sleeve is inserted into an annular space in the bolt carrier when the sleeve is radially compressed allowing relative movement between the bolt head and bolt carrier. The sleeve is supported between the bolt head and an end surface of the bolt carrier when the sleeve is expanded preventing relative movement between the bolt head and the bolt carrier. The periphery of the uncompressed elastic sleeve contacts the bolt carrier or bolt head to thereby effectively damp the elastic sleeve.

6. A firearm comprising:
-
a barrel with a locking element at the proximal end of the barrel;

10. For use in a firearm having a barrel and a locking element formed at the proximal end of the barrel, a bolt assembly comprising:
-
a bolt carrier;
a bolt head at least partially received by the bolt carrier;
an elastic sleeve mounted on the bolt head and having an expanded state and a compressed state, the elastic sleeve contacting the bolt carrier and the bolt head in the expanded state to thereby substantially prevent relative longitudinal movement between the bolt head and the bolt carrier, whereby compression of the sleeve from the expanded state towards the compressed state permits relative longitudinal movement between the bolt head and the bolt carrier; and
means for damping vibrations of the elastic sleeve.
