US12535284 - Linear trigger bolt action firearm

Disclosed is a linear trigger mechanism for a firearm. In certain examples, the trigger mechanism includes a trigger housing having a linear trigger pathway and a removeable side plate. The trigger mechanism also includes a trigger that is at least partially disposed between the trigger housing and the removeable side plate, where the trigger is configured to move between a first position and a second position along a path that is defined by the trigger pathway, and where the trigger includes an angled sear engagement surface. The trigger mechanism also includes a sear that is at least partially disposed between the trigger housing and the removeable side plate and is configured to pivot with respect to the trigger housing, where the sear includes an angled trigger engagement surface that corresponds with the angled sear engagement surface.

The patent describes a linear trigger mechanism for firearms that features a trigger housing with a linear pathway and a removable side plate, allowing for a trigger to move between two positions to actuate a firing pin. It includes a sear that pivots with respect to the housing and utilizes angled engagement surfaces and a roller pin to transfer force from the trigger to the sear.

Claim 1

1 . A trigger mechanism for a firearm, comprising: a trigger housing having a linear trigger pathway; a removeable side plate; a trigger that is at least partially disposed between the trigger housing and the removeable side plate, where the trigger is configured to move between a first position and a second position to actuate a firing pin along a path that is defined by the trigger pathway, and where the trigger includes an angled sear engagement surface with respect to the linear trigger pathway; a sear that is at least partially disposed between the trigger housing and the removeable side plate and is configured to pivot with respect to the trigger housing, where the sear includes an angled trigger engagement surface that corresponds with the angled sear engagement surface; a roller pin captured between the angled sear engagement surface and the angled trigger engagement surface, where the roller pin is configured to transfer a force applied to the trigger to the sear. a trigger housing having a linear trigger pathway; a removeable side plate; a trigger that is at least partially disposed between the trigger housing and the removeable side plate, where the trigger is configured to move between a first position and a second position to actuate a firing pin along a path that is defined by the trigger pathway, and where the trigger includes an angled sear engagement surface with respect to the linear trigger pathway; a sear that is at least partially disposed between the trigger housing and the removeable side plate and is configured to pivot with respect to the trigger housing, where the sear includes an angled trigger engagement surface that corresponds with the angled sear engagement surface; a roller pin captured between the angled sear engagement surface and the angled trigger engagement surface, where the roller pin is configured to transfer a force applied to the trigger to the sear.
