Trigger assembly

摘要

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 and 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.

主权项

1. A trigger assembly for activating a firing mechanism, the trigger assembly being mountable in a housing, the trigger assembly comprising:
a trigger pivotally 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 pivotally mounted on a firing element pivot pin, the firing element comprising: a body portion comprising a second sear surface; an engagement portion for engagement with at least a portion of the firing mechanism, for activating the firing mechanism; a captured roller positioned for engagement with the first and second sear surfaces; 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.
