US12320600 - Reduced friction, low profile trigger mechanism

A trigger mechanism assembly for a firearm provides a horizontal arrangement of its sear relative to a trigger of the firearm by way of a linkage bar. The sear and a disconnector share a pivot point, wherein at each engagement surface between the pivot point and the sear and the disconnector, respectively, there is a bearing. A pair of mandibles is provided, one mandible by each of the sear and the disconnector. A spring is operatively associated between the sear and the disconnector to bias them to rotate about the pivot point dependently, whereby a first distance between the pair of mandibles is maintained. An inclined surface is provided along at least one mandible so that a downward force urged by a hammer against the inclined surface moves the disconnector independently of the sear, whereby a second distance between the pair of mandibles is greater than the first distance.

The patent describes a trigger mechanism assembly for firearms that features a horizontal arrangement of the sear and disconnector, utilizing a linkage bar and bearings to enhance performance. This design allows for independent movement of the disconnector in response to the hammer, improving trigger function and reducing friction.

Claim 1

A trigger mechanism assembly for a firearm, the assembly comprising: a sear and a disconnector concentrically sharing a pivot point; a sear bearing and a disconnector bearing operatively associated with the sear and the disconnector, respectively, and the pivot point; and a horizontal-oriented linkage bar having a distal end and a proximal end, wherein the distal end is directly connected to the sear and the proximal end is operatively associated with a trigger of the firearm. a sear and a disconnector concentrically sharing a pivot point; a sear bearing and a disconnector bearing operatively associated with the sear and the disconnector, respectively, and the pivot point; and a horizontal-oriented linkage bar having a distal end and a proximal end, wherein the distal end is directly connected to the sear and the proximal end is operatively associated with a trigger of the firearm.
