Magnetically actuated sear

摘要

A magnetically actuated sear for simulated firearm training is disclosed. The magnetically actuated sear includes a magnet and a magnet catch. The magnetically actuated sear facilitates a crisp trigger break thereby replicating the actual sear release of a firearm. The application of a suitable external trigger force causes the magnet catch to travel along the fulcrum away from the magnet. The greater the difference between the holding force when the magnet is in direct contact with the magnet catch and the attraction force between the magnet and the magnet catch, the crisper the magnetically actuated sear will feel. The magnetically actuated sear can be designed so that slack or trigger creep of the magnetically actuated sear can be matched to the actual firearm's slack or trigger creep.

主权项

1. A magnetically actuated sear for a trigger of a firearm and/or a simulated firearm, the magnetically actuated sear comprising:
(i) a trigger body; (ii) a magnet affixed to the trigger body; (iii) a magnet catch, wherein the magnet catch is aligned parallel to the magnet; (iv) a fulcrum which extends through the magnet catch and affixes the magnet catch to the trigger body, wherein the magnet catch is configured to pivot on the fulcrum; (v) a trigger engagement device, wherein the trigger engagement device is affixed to a first longitudinal end of the magnet catch; (vi) a pushing device, wherein a first end of the pushing device is in engagement with the trigger engagement device and wherein a second end of the pushing device extends through the trigger body; and wherein the magnetically actuated sear excludes a spring for resetting the sear, wherein prior to an application of an external force to the pushing device, a first surface of the magnet catch is in a magnetically cooperating relationship with the magnet at a second longitudinal end of the magnet catch, wherein the magnet catch is separated from the cooperating relationship with the magnet and moved to a predetermined distance upon application of an external force to the pushing device wherein the external force is applied in a direction which is perpendicular to a longitudinal axis of the magnet catch, and wherein, upon release of the external force to the pushing device, a resetting of the magnetically actuated sear is facilitated only by magnetic attraction between the magnet and the magnet catch.
