Abstract
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.
Claims18
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 trigger mechanism, comprising:
- a housing;
- a main sear rotatably coupled to the housing;
- an actuator rotatably coupled to the housing, the actuator engageable with the main sear to prevent rotation of the main sear;
- a trigger configured to disengage the actuator from the main sear when the trigger is rotated;
- a striker sear rotatably coupled to the housing and linked to the main sear;
- a striker translatable towards and away from a firearm barrel, wherein the striker sear is releasable from engaging the striker when the actuator is disengaged from the main sear;
- and
- a first biasing member and a second biasing member, the first biasing member and the second biasing member each configured to adjustably bias a same portion of the actuator relative to the main sear.
A trigger mechanism, comprising:
- a housing;
- a main sear rotatably coupled to the housing;
- a trigger sear rotatably coupled to the housing, the trigger sear engageable with the main sear to prevent rotation of the main sear;
- a trigger configured to disengage the trigger sear from the main sear when the trigger is rotated;
- a first adjustable biasing member engageable with a contact area on the trigger sear to provide a first amount of rotational resistance corresponding to a minimum trigger pull weight;
- a second adjustable biasing member engageable with the contact area on the trigger sear to provide a second amount of rotational resistance corresponding to an additional trigger pull weight accumulative to the minimum trigger pull weight;
- and
- a trigger sear pin rotatably coupling the trigger sear to the housing, wherein:
- the contact area comprises a first contact point for the first adjustable biasing member and a second contact point for the second adjustable biasing member;
- the first contact point is a first distance from the trigger sear pin and the second contact point is a second distance from the trigger sear pin that is less than the first distance.
