摘要： A sear trip bar for use in an automatic firearm is disclosed. In accordance with some embodiments, the sear trip bar can be operatively interfaced with the bolt carrier and the automatic sear of the host firearm. The disclosed sear trip bar can be configured such that, upon sufficient displacement thereof (e.g., exhaustion of its stroke length) by the bolt carrier, the automatic sear may be caused to trip. Thus, the disclosed sear trip bar can be utilized, for example, to transfer the force of the moving bolt carrier during a given firing cycle to automatically trip the sear so as to initiate one or more subsequent firing cycles without having to release and again operate the trigger of the host firearm. The disclosed sear trip bar can be utilized, for example, in pistol-caliber and/or rifle-caliber automatic firearms.

摘要： A roller sear/hammer interface for a firearm. The sear has a roller rotatably mounted between two side plates forming a portion of the sear body. As the trigger is moved, a linkage connecting the trigger and sear causes the sear to pivot rearward such that the roller engages a notched surface formed in the hammer. This rolling action releases the hammer to strike a firing pin to fire a round of ammunition. When the trigger is released, the sear roller rolls downward into an engaged and locked position within the notch formed in the hammer.

摘要： A handgun comprises a frame, a trigger pivotally mounted on the frame for movement between a rest position and a depressed position, and a hammer pivotally mounted on the frame in spaced relation to the trigger. A trigger bar is pivotally connected to the trigger and extends into operative relation with the hammer for cocking the hammer when the trigger is moved to the depressed position. A biasing member has a first end connected to the frame and a second end connected to the trigger bar for biasing the trigger bar in a direction into operative relationship with the hammer and in a direction for returning the trigger to the rest position from the depressed position.

摘要： A functioning mechanism for a small caliber automatic weapon includes a translatable and rotatable sear, and a rotatable hammer. The sear includes a hooking element adapted to contact a bearing surface of the hammer to render the hammer immobile. Rotating movement of the sear is controlled by the hammer in such a way as to obtain clean contact between the hooking element and the bearing surface.

摘要： This invention relates to hand-held light weapon firing devices. To resolve the present problem of the excessive length of the work travel of the firing device trigger, with large frictional surface resistance between the blocking iron and the track, thus directly affecting the precision of firing. It is characterized in that it has a rotating blocking iron, which is fixed to the firing mount by the rotating blocking iron shaft; the rotating blocking iron shaft, the rotating blocking iron shaft hole and the hole in the frame for the rotating blocking iron shaft together forming a rotating assembly. This converts the translational friction of the original blocking iron on the track into rotational friction, the linear translational motion of the original blocking iron becoming the eccentric rotational motion of the rotating blocking iron, reducing the length of travel of the trigger from 6.about.7 mm to 2.about.2.5 mm, reducing frictional resistance and making it easy to operate during firing, thus creating the conditions for improvement in and guarantee of precision in firing.

摘要： A semiautomatic firing mechanism for an autoloading firearm. A generally C-shaped hammer is pivotably mounted behind a bolt, with a transversely-extending sear piece located below the rearwardly-facing open side of the hammer. The open ends of the hammer provide ledges selectively engageable with primary and secondary sear surfaces on the sear piece.

摘要： Inserted into the receiving chamber of the lock (i.e., trigger, sear and hammer) of a trap type shotgun is an elongated U-shape housing having on the forward end a spring supported loading platform adapted to receive and temporarily carry a shotgun shell inserted through the uncovered ejection port when the breech bolt is retracted rearwardly into open position. Rearward movement of the bolt is simultaneously effective to engage and depress a spring-biased hammer pivotally mounted on the housing, the hammer including a notch for engagement with the latch hook of a sear rockably mounted on the housing. A spring-urged trigger has a portion overlying a flange on the sear so that actuation of the trigger moves the sear latch hook out of engagement with the hammer, thereby allowing the hammer to spring forwardly and strike the firing pin. A safety lever positively immobilizes the trigger in open bolt position and, for automatic shotguns, a bolt detent structure holds the bolt open after each shot until a shell is inserted and a separate trip lever is actuated so as to allow the bolt to close.
