Trigger assembly
First Claim
1. A trigger assembly for activating a firing mechanism, the trigger assembly being mountable in a housing, the trigger assembly comprising:
- a trigger pivotably mounted on a trigger pivot pin, the trigger comprising;
an elongate trigger arm extending between a top end proximal to the trigger pivot pin and a bottom end distal to the trigger pivot pin;
a sear arm positioned transverse to the trigger arm, the sear arm comprising a first sear surface;
a firing element pivotably mounted on a firing element pivot pin, the firing element comprising;
a body portion comprising a second sear surface; and
an engagement portion for engagement with at least a portion of the firing mechanism, for activating the firing mechanism;
a guide connected to one of the sear arm or the firing element, the guide defining a pair of apertures adjacent to one of the first and second sear surfaces;
a captured roller positioned for engagement with the first and second sear surfaces, the captured roller at least partially positioned in the pair of apertures;
the trigger being pivotable about the trigger pivot pin between a load position, in which the captured roller is held between the first and second sear surfaces, and a release position, in which the second sear surface is disengaged from the captured roller and the firing element is released; and
the firing element being pivotable about the firing element pivot pin between a first position, in which the firing element is held by the engagement of the second sear surface with the captured roller when the trigger is in the load position thereof and the firing mechanism is activatable by the engagement portion, and a second position, in which the firing element is disengaged from the captured roller and the firing mechanism is activated by the engagement portion, the firing element being movable to the second position upon the trigger moving to the release position thereof.

Abstract
A trigger assembly for activating a firing mechanism. The trigger assembly includes a trigger having a sear arm with a first sear surface, and a firing element including a body portion with a second sear surface and an engagement portion for engagement with the firing mechanism, for activating the firing mechanism. The trigger assembly also includes a captured roller positioned for engagement with the first end second sear surfaces. The trigger is pivotable between a load position, in which the captured roller is held between the first and second sear surfaces, and a release position, in which the second sear surface is disengaged from the captured roller and the firing element is released. The firing element is pivotable between a first position, in which the firing element is held by the captured roller, and a second position, in which the firing element is disengaged from the captured roller.

16. A trigger assembly for mounting in a housing in a crossbow, the housing having an opening at a forward side thereof in which a bowstring is at least partially positionable in a drawn position thereof, the trigger assembly comprising:
-
a trigger pivotably mounted on a trigger pivot pin supported in the housing, the trigger comprising; an elongate trigger arm extending between a top end proximal to the trigger pivot pin and a bottom end distal thereto;
a sear arm positioned transverse to the trigger arm, the sear arm comprising a first sear surface;a firing element pivotably mounted on a firing element pivot pin supported in the housing, the firing element comprising; a body portion comprising a second sear surface; and a hook portion; a guide connected to one of the sear arm or the firing element, the guide defining a pair of apertures adjacent to one of the first and second sear surfaces; a captured roller positioned for engagement with the first and second sear surfaces, the captured roller at least partially positioned in the pair of apertures; the trigger being pivotable about the trigger pivot pin between a load position, in which the captured roller is held between the first and second sear surfaces, and a release position, in which the second sear surface is disengaged from the captured roller and the firing element is released; and the firing element being pivotable about the firing element pivot pin between; a hooked position, in which the firing element is held by the engagement of the second sear surface with the captured roller when the trigger is in the load position thereof and the firing mechanism is activatable by the engagement portion, the bowstring being retainable by the hook portion when the firing element is in the hooked position; and an open position, in which the firing element is disengaged from the captured roller and the bowstring is releasable from the firing element, the firing element being movable to the open position upon the trigger moving to the release position thereof. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
