Abstract
A trigger mechanism for a rifle having a trigger housing, a trigger, a cocking piece, a bolt lock, a pivotable safety key, a pivotable sear, a sear engagement, and a ball détente spring. The sear engagement is fixedly attached to the upper part of the trigger. The safety key has a bolt lock guide that is configured to move the bolt lock among three different positions, each of which corresponds to a position of the ball détente spring on the inside of the safety key. When the bolt lock is in the first position, neither the bolt nor the trigger can move. When the bolt lock is in the second position, the bolt is free to rotate, but the trigger cannot move. When the bolt lock is in the third position, the bolt is free to move, and the trigger can also move.
Claims9
A trigger mechanism for a rifle comprising:
- (a) a trigger housing;
- (b) a trigger;
- (c) a cocking piece;
- (d) a bolt lock;
- (e) a safety key that is configured to pivot relative to the trigger housing;
- wherein the safety key comprises a bolt lock guide;
- wherein the bolt lock guide is configured to fit within a recess in the bolt lock;
- wherein the bolt lock guide is configured to move among a first position, a second position, and a third position as the safety key is rotated;
- and
- wherein when the bolt lock guide is in the first position, the bolt is prevented from rotating, and when the bolt lock guide is in the second position or the third position, the bolt is free to rotate;
- (f) a sear that is pivotally connected to the trigger housing at a sear pivot point;
- wherein the sear is configured to pivot between a first position and a second position;
- and
- wherein when the sear is in the first position, the sear is configured to prevent the cocking piece from moving forward, and when the sear is in the second position, the cocking piece is able to move forward;
- (g) a sear engagement that is fixedly attached to an upper part of the trigger and configured to rock forward when a bottom part of the trigger is pulled by a user;
- wherein when the bolt lock guide is in the first position or the second position, a rear end of the bolt lock guide abuts up against a front face of the sear engagement, thereby preventing the sear engagement from rocking forward;
- and
- wherein when the bolt lock guide in the third position, the sear engagement is free to rock forward;
- and
- (h) a ball detent spring;
- wherein the ball detent spring is configured to move among a first position, a second position, and a third position on an inside surface of the safety key.
