Sprung Drop Pendulum
First Claim
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 contact surface;
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 drop pendulum movably mounted within said assembly and moving during operation of said firearm, said drop pendulum having a trigger cam engageable with said trigger;
a pendulum spring positioned between said trigger and said drop pendulum for biasing said trigger cam into engagement with said trigger.

Abstract
A trigger assembly has a sear with a stop surface engageable with a reciprocating component for holding the reciprocating component in a cocked configuration. A trigger is movable into and out of engagement with the sear to hold and release the reciprocating component. A drop pendulum has a trigger cam engageable with the trigger. A spring acts between the trigger and the drop pendulum to bias the trigger cam into engagement with the trigger. The drop pendulum also has a head cam follower engageable with the reciprocating component. Motion of the reciprocating component acting through the head cam follower and the trigger cam forces the trigger to return to a configuration of engagement between the trigger and the sear. Use of the drop pendulum improves the stability of trigger mechanisms and effectively inhibits accidental discharge of firearms when subjected to inertial forces which occur when the firearm is dropped.
