US12313357 - Flexible hinge based trigger for a firearm

A mechanism using flexure hinges as part of the trigger and/or safety mechanism of a firearm. Flexure hinges provide relative motion between two stiff members by the elastic deformation of an arbitrarily shaped flexible connector often implemented in metallic and composite materials. The flexure hinges are formed by flexure links connecting two stiff members. The flexure links connect various parts of the trigger assembly, such as a trigger component, including a shoe, plate, or safety, to a housing of the firearm. A method of creating the mechanism provides a trigger component, a housing, and connects the two parts by a flexure link with a flexure hinge.
