US12345489 - Trigger mechanism for a firearm

Embodiments of the present disclosure relate to trigger mechanisms for firearms. In one aspect of the present disclosure, the trigger mechanism can include a linkage between a striker sear and a main sear to control an amount of force exerted on the main sear by the striker sear. A portion of the force exerted on the striker sear by the striker can be exerted on the main sear through the sear linkage. In another aspect of the present disclosure, trigger mechanisms are described which additionally, or alternatively utilize one or more biasing members to provide a variable trigger pull weight.

The patent describes a trigger mechanism for firearms that includes a linkage between a striker sear and a main sear, allowing control over the force exerted on the main sear. It features adjustable biasing members to provide variable trigger pull weights, enhancing user customization and control.

Claim 1

A trigger mechanism, comprising: a housing; a first sear rotatably coupled to the housing; a second sear rotatably coupled to the housing, the second sear engageable with the first sear to prevent rotation of the first sear; a trigger configured to disengage the second sear from the first sear when the trigger is rotated; a third sear rotatably coupled to the housing; a striker translatable towards and away from a firearm barrel, wherein the third sear is engageable with the striker; a first adjustable biasing member engageable with a contact area on one of the trigger or the second sear to provide a first amount of rotational resistance corresponding to a baseline trigger pull weight; and a second adjustable biasing member engageable with a same one of the trigger or the second sear at the contact area to provide a second amount of rotational resistance corresponding to additional trigger pull weight. a housing; a first sear rotatably coupled to the housing; a second sear rotatably coupled to the housing, the second sear engageable with the first sear to prevent rotation of the first sear; a trigger configured to disengage the second sear from the first sear when the trigger is rotated; a third sear rotatably coupled to the housing; a striker translatable towards and away from a firearm barrel, wherein the third sear is engageable with the striker; a first adjustable biasing member engageable with a contact area on one of the trigger or the second sear to provide a first amount of rotational resistance corresponding to a baseline trigger pull weight; and a second adjustable biasing member engageable with a same one of the trigger or the second sear at the contact area to provide a second amount of rotational resistance corresponding to additional trigger pull weight.
