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.
Claims20
A trigger mechanism, comprising:
- a housing;
- a first sear;
- a second sear coupled to the first sear, the second sear being rotatable relative to the housing;
- a third sear rotatably coupled to the housing, the third sear forming a surface that engages with a distal end of the second sear to prevent rotation of the second sear;
- and
- a trigger configured to disengage the surface of the third sear from the distal end of the second sear when the trigger is rotated.
A firearm comprising:
- a stock;
- a barrel;
- a receiver configured to couple to the stock and the barrel;
- a bolt assembly including a firing pin;
- a trigger mechanism disposed at least partially within the receiver, the trigger mechanism comprising:
- a housing;
- a striker sear;
- a main sear coupled to the striker sear and rotatably coupled to the housing;
- a trigger sear rotatably coupled to the housing, the trigger sear engaging with the main sear to prevent rotation of the main sear;
- and
- a trigger;
- wherein the trigger sear disengages from the main sear to permit rotation of the main sear when the trigger is rotated.
A trigger mechanism, comprising:
- a housing;
- a sear rotatably coupled to the housing;
- an actuator rotatably coupled to the housing, the actuator engaging with the sear to prevent rotation of the sear;
- a trigger configured to disengage the actuator from the sear when the trigger is rotated;
- a first biasing member and a second biasing member, the first biasing member and the second biasing member configured to bias the actuator and the sear to engage one another.
