Fire Control / Trigger Mechanism

Abstract

A trigger mechanism or fire control for trigger operable devices includes a housing; a sear having a sear body coupled to the housing and including a primary engagement surface and an active sear support reset geometry; and a sear support coupled to the housing and having a body with a sear engagement surface and a passive sear support reset geometry. The primary engagement surface of the sear is moved into an overlapping condition with the sear engagement surface of the sear support as the sear is moved from a discharged position to a reset position after actuation of the trigger operable device. In addition, interaction between the active sear support reset geometry and the passive sear support reset geometry causes a mechanical displacement of the sear support to a reset position.

What is claimed is: 
     
         1 . A firearm, comprising:
 a cocking piece moveable between a cocked position and a discharged position; and   a fire control comprising:
 a sear having a sear support reset cam and configured to engage the cocking piece when the cocking piece is in the cocked position; and 
 a sear support having a sear support reset channel extending at least partially therealong; and 
   wherein the sear support reset cam of the sear is at least partially received in the sear support reset channel of the sear support as the sear is moved between one or more positions.
