Trigger return and drop pendulum

摘要

A trigger assembly has a sear with a stop surface engageable with a reciprocating component for holding the reciprocating component in a cocked configuration. The sear also has a sear cam engageable with a lever movably mounted within the assembly. A trigger is movable into and out of engagement with the lever. Pulling the trigger moves it out of engagement with the lever and releases the sear. A trigger return pendulum has a trigger cam engageable with the trigger, a lever cam engageable with the lever, and a head cam follower engageable with the reciprocating component. Motion of the reciprocating component acting through the head cam follower of the trigger return pendulum forces the lever cam into engagement with the lever and the trigger cam into engagement with the trigger to return the lever and the trigger to a configuration of engagement between the trigger and the lever.

1. A trigger assembly for a firearm having a reciprocating component, said trigger assembly comprising:
a sear movably mounted within said assembly, said sear having a stop surface engageable with said reciprocating component for holding said reciprocating component in a cocked configuration, said sear further comprising a sear cam; a lever movably mounted within said assembly, said lever having a contact surface, said sear cam engaging said lever; a trigger movably mounted within said assembly, said trigger having an action surface movable into and out of engagement with said contact surface upon motion of said trigger; a spring acting on said lever and biasing said contact surface out of engagement with said action surface; a trigger return pendulum movably mounted within said assembly, said trigger return pendulum having a trigger cam engageable with said trigger, a lever cam engageable with said lever, and a head cam follower engageable with said reciprocating component; wherein motion of said reciprocating component acting through said head cam follower of said trigger return pendulum forces said lever cam into engagement with said lever and said trigger cam into engagement with said trigger to return said lever and said trigger to a configuration of engagement between said action surface and said contact surface.
