Abstract
A trigger mechanism or fire control for trigger operable devices includes a housing; a sear having a sear body coupled to the housing and including a primary engagement surface and an active sear support reset geometry; and a sear support coupled to the housing and having a body with a sear engagement surface and a passive sear support reset geometry. The primary engagement surface of the sear is moved into an overlapping condition with the sear engagement surface of the sear support as the sear is moved from a discharged position to a reset position after actuation of the trigger operable device. In addition, interaction between the active sear support reset geometry and the passive sear support reset geometry causes a mechanical displacement of the sear support to a reset position.
Claims20
A trigger mechanism, comprising:
- a sear having a sear body, the sear body comprising a sear support reset cam;
- and
- a sear support, the sear support having a sear support body at least partially defining a sear support reset channel having a sear support over travel limiting surface;
- wherein the sear support reset cam comprises an over travel limiting surface configured to substantially stop movement of the sear support by contacting the sear support over travel limiting surface;
- and
- wherein the sear support reset cam of the sear body is at least partially received in the sear support reset channel of the sear support, with the sear support reset cam traversing along at least a portion of the sear support reset channel as at least one of the sear and the sear support is moved between a plurality of positions.
A firearm, comprising:
- a striker assembly;
- a cocking piece moveable between a cocked position and a discharged position and configured to place the striker assembly in a ready-to-fire position when the cocking piece is in a cocked position;
- and
- a fire control comprising:
- a sear having a sear body, the sear body comprising a sear support reset cam, wherein at least a portion of the sear is configured to engage the cocking piece when the cocking piece is in the cocked position for holding the striker assembly in the ready-to-fire position;
- and
- a sear support, the sear support having a sear support body at least partially defining a sear support reset channel;
- wherein the sear support reset cam of the sear is at least partially received in the sear support reset channel of the sear support, the sear support reset cam traversing along at least a portion of the sear support reset channel as the sear is moved between a plurality of sear positions;
- wherein the sear further comprises at least one engagement surface defined along the sear body;
- and
- wherein the sear support comprises a sear engagement surface located along the sear support body and configured to engage the at least one engagement surface of the sear when the cocking piece is in the cocked position.
A trigger mechanism, comprising:
- a sear having a sear support reset cam defined therealong;
- and
- a sear support including a sear support body having a sear support reset channel defined therealong;
- wherein the sear support reset cam of the sear is at least partially received in the sear support reset channel of the sear support, the sear support reset cam traversing along at least a portion of the sear support reset channel as at least one of the sear and the sear support is moved between a plurality of positions;
- wherein the plurality of positions includes at least a discharged position and a reset position;
- wherein the sear support reset cam is configured to travel along the sear support reset channel as the at least one of the sear and the sear support is moved from the discharged position to the reset position;
- and
- wherein the sear support reset cam is configured to contact a sear support reset surface of the sear support reset channel as the sear support reset cam travels along the sear support reset channel so as to urge the sear support to move to the reset position.
