EA028126B1 - Trigger and firing mechanism of automatic weapons - Google Patents

Abstract

The invention relates to automatic weapons, i.e. trigger and firing mechanisms, which provide firing in the single-shot and automatic modes and in the automatic burst mode. The trigger and firing mechanism contains a trigger, a rod, a firing pin, a spring-loaded sear, a spring-loaded free rod, a spring-loaded inertia plunger with a safety lock, a rod with a spring and a fire selector. The spring-loaded sear is installed in a modular body wit attachment option; herewith a modular body is installed on pins and spring-loaded. The modular body is fitted with a separator, which prevent a shot when the breech mechanism and the safety lock are not fully closed. The technical result of the invention is the development of a hammerless trigger and firing mechanism, which provides firing in the single-shot and automatic modes and in the automatic burst mode limited to 2 rounds.

Description

The invention relates to automatic firearms, and in particular to trigger mechanisms providing single, automatic firing and automatic firing with a limited number of shots.

The closest analogue is the trigger mechanism of the GSh-18 pistol (see No. # 8LOO1shd-ia.sot / agt-boook8 / agt bok 58, as well as the book by S. Fedoseyev Russian Combat Small Arms. Vanguard Publishing House) containing trigger, traction, firing pin, whisper, and firing type trigger mechanism with partial cocking of the firing pin after the shutter is released is used. For pre-launching and descent, a complete pull on the trigger is necessary. The trigger mechanism provides single-shot firing. The disadvantage of this mechanism: - lack of automatic firing mode.

The objective of the invention is the creation of a trigger mechanism for firearms, providing a technical result, consisting in the creation of a bezkurkovoy trigger mechanism, providing single automatic firing and automatic firing with a limited number of shots of 2.

The task is achieved in that the trigger mechanism of a firearm, providing single automatic firing and automatic firing with a limited number of shots of 2 each, containing a trigger, traction, striker, is characterized in that it is equipped with a spring loaded sear installed in a spring-loaded modular housing with the possibility of fixation, additional spring-loaded free traction, spring-loaded inertial pusher with fuse, fire translator, rod with spring, interaction with a trigger and free traction, and the modular housing is equipped with a fuse and disconnector.

The invention is illustrated by drawings, where in FIG. 1 shows a general left view of the firing mechanism in the pre-firing position mounted on a fuse; in FIG. 2 - general left view of the trigger mechanism at the time of the shot; in FIG. 3 is a general left view of the trigger mechanism during the bolt back stroke; in FIG. 4 - a general view of the right trigger mechanism, inertial pusher on the fuse; in FIG. 5 is a general right view of the trigger mechanism, the bolt frame rolls back after the 1st shot, preparation of the second shot; in FIG. 6 is a general right view of the trigger mechanism after the second automatic shot and ceasefire; in FIG. 7 is a top view of the shutter; in FIG. 8 is a top view of a sear in a modular housing; in FIG. 9 rear view of the trigger mechanism, the drummer cocked.

The trigger mechanism includes a trigger 1, rod 2, spring loaded with spring 3, drummer 4, spring of drummer 5, whispered 6, spring loaded with spring 7, body whispered 8, spring loaded with spring 9, tooth 10, rod with spring 11, free rod 12, spring-loaded pressing and return springs 13 and 14, respectively, the inertial pusher 15 with the spring 16, the fuse of the inertial pusher 17, the fire translator 18, the fuse 19, the disconnector 20.

Before firing, the fire translator 18 and the fuse of the inertial pusher 17 are installed in one of the positions that determine the firing mode: single automatic firing or automatic firing with a limited number of shots of 2.

Single shooting occurs as follows. Before firing, the inertial pusher 15 is mounted on the fuse 17. When you press the trigger 1, the rod 2 with its rear ledge pulls the sear 6 into the housing 8, while the sear 6 is released from the tooth 10. The sear body 8 is rotated by the action of the spring 9 on the trunnions and releases the hammer 4. A shot occurs.

Automatic shooting with a limited number of shots of 2 is as follows. Before firing, the inertial pusher 15 is removed from the fuse 17, and the fire translator 18 is set to position A. When the trigger 1 is pressed simultaneously with the rod 2 moving forward (see single shooting), the trigger 1 lifts the rod 11 with its rear protrusion, which in turn, it lifts the free traction 12. After the first shot, the bolt frame rolls back, turns the housing 8 back while the whisper 6 is pulled into the housing 8 by the action of the tooth 10 and, under the action of the spring 7, rests under the tooth 10. Then the shutter turns on flushes the disconnector 20 which is essentially a modular automatic fuse housing 8 as a lever on the axle, which at its lower end puts unit 8 to stop.

When the bolt moves forward, the next cartridge is sent to the chamber, the isolator 20 releases module 8 from the stop. The barrel channel closes, while the inertia pusher 15 inertia moves forward with the front protrusion, pushes the free rod 12 forward, the spring 14 is compressed, the rear protrusion of the rod 12 retracts the sear 6 into the housing 8. The housing 8 under the action of the spring 9 is rotated on the pins and releases the hammer 4, a second shot occurs. Simultaneously with the release of the firing pin 4, the thrust 12 with its front end abuts against the upper protrusion of the fire translator 18 and, under the action of the spring 13, goes down in an arc and extends beyond the rod 11 with its lower protrusion, shooting stops.

To produce the next stage, you must release the trigger 1, which under the action of the rod with the spring 11 returns to its original position. At the same time, the rod 2 with its rear protrusion engages with the front protrusion of the whisper 6, and the free rod 12 under the action of the spring 14 returns.

Automatic shooting is as follows. Before firing, the inertial pusher 15 is removed from the fuse 17, and the fire translator is set to position B. Shooting occurs similarly to firing with a limited number of shots of 2, the difference is that the free rod 12 when moving forward under the influence of the inertial pusher 15 moves from the rod 11 to fire translator housing 18 and vice versa. Shooting continues until trigger 1 is released.

Thus, the trigger mechanism of a firearm provides single automatic firing and automatic firing with a limited number of shots of 2.
