Abstract

FIELD: weapons and ammunition.

SUBSTANCE: invention refers to small arms. A self-loading pistol includes a frame, a bolt, a recoil spring, a trigger, a sear, a trigger bar, a release trigger, a firing spring with a tie-rod of the firing spring, a spring of the sear and a spring of the release trigger. On the bolt there is a projection formed on the lower part of the bolt between two slots located one after another in a longitudinal direction and having flat edges. At movement of the bolt, the projection interacts with the trigger bar; with that, it recesses the trigger bar both at backward movement of the bolt and at forward movement of the bolt. Such design allows quick placing of the pistol by single pressing of the trigger into a fire position. Now, the following pistol parts are used for putting the trigger to a half-cock position: the bolt and the release trigger.

EFFECT: achievement of a possibility of automatic putting of a trigger both to a full-cock position and to a half-cock position with simultaneous simplification of the pistol design and improvement of ease of its use.

Description

The invention relates to the field of small arms, in particular to self-loading pistols, and is aimed at improving their design.

When loading pistols with a trigger, which have the ability to fire both from a combat platoon and self-cocking, the trigger is placed on the combat platoon.

If it is necessary to put a charged pistol in a holster, then the trigger is transferred from the combat platoon to the safety platoon.

In most pistols, for this, pull the trigger with one hand, and holding the trigger with the other, transfer it to the safety platoon (Beretta 92, CP1 pistols).

In some pistols, the trigger is switched from a combat platoon to a safety platoon using a flag fuse (Makarov pistol).

In some pistols, the trigger is transferred from a combat platoon to a safety platoon using a special lever (SIG-Sauer P226).

The closest technical solution to the proposed invention is a self-loading pistol SIG-Sauer P228 of the same Swiss-German company. This gun contains a frame, bolt, magazine and trigger trigger, double action with a safety cocking trigger. When loading a pistol, the trigger is placed on the cocking unit. To transfer the trigger of a charged pistol from a combat cock to a safety cock, press the lever located on the right side of the frame. In this case, the lever, turning around its axis, shanks the sear out of engagement with the trigger. The trigger under the action of the mainspring turns and rests on the lever. When lowering the lever, the trigger, resting on the lever, turns and becomes on the safety cock.

The disadvantage of this gun is the presence of a number of additional parts designed to transfer the trigger from the combat to the safety cock: the lever protruding from the side of the gun located on a special axis and spring-loaded.

The objective of the invention is to develop the design of the gun, allowing when loading the gun to automatically set the trigger as a combat cock and a safety cock, while simplifying its design and increasing the convenience of its use.

To do this, in a self-loading pistol containing a frame, a bolt, a return spring, a trigger, a whisper, a trigger rod, a trigger, a mainspring with a mainspring rod, a whisper spring and a trigger spring, a protrusion is formed on the shutter formed on the lower part of the shutter between two located one after the other in the longitudinal direction with grooves having gently sloping edges. When the shutter moves, the protrusion interacts with the shutter rod, while it drowns the shutter rod both when the shutter moves backward and when the shutter moves forward.

This design allows you to quickly, with one click on the trigger, bring the pistol into combat position. To set the trigger on the safety platoon, the details of the gun are now used: the shutter and the trigger. It lacks additional details used in the prototype.

The drawings depict a gun made according to the invention:

Figure 1 - details of the gun are in position before loading;

Figure 2 - details of the gun are shown when the bolt is in the extreme rear position;

Figure 3 - details of the gun are shown when the bolt is in the extreme rear position and the trigger is released;

Figure 4 - details of the pistol are shown when the shutter ceased to hold the trigger and the trigger turned under the action of the mainspring, watching the shutter. The protrusion on the bolt disengages the traction from the sear.

The self-loading pistol (Fig. 1) contains a frame 1, a shutter 2, a return spring 3, a trigger 4, a sear 5, a trigger rod 6, a trigger 7, a main spring with a mainspring rod 8, a whisper spring 9, a trigger spring 10 and a magazine (not shown in the drawing). On the lower surface of the shutter, two grooves with flat edges are made one after another in the longitudinal direction: front 11 and rear 12, between which there is a protrusion interacting with the uncoupling protrusion 13 of the trigger rod.

The front wall of the rear groove 12 serves to disconnect the trigger rod with the sear when the bolt rolls back during the shot. The rear wall of the front groove 11 serves to disconnect the trigger rod with the sear, when when loading it is necessary to put the trigger on the safety cock.

Before loading the gun, its parts according to figure 1 are in the following position. The shutter 2 under the action of the return spring 3 is in its extreme forward position. The trigger 7 under the action of its spring 10 is in the extreme forward position, and the trigger rod 6 is in the extreme rear position. Whisper 5 under the action of its spring is pressed by the retaining protrusion 14 to the trigger. The trigger under the action of the mainspring is pressed with its safety protrusion 15 to the holding protrusion 14 of the sear.

In order for the trigger to be put on the safety cock when reloading, it is enough to take the shutter to its extreme rear position (figure 2) when the magazine is inserted, pull the trigger (figure 3) and, while holding the trigger, release the shutter. Wherein:

- when you press the trigger when the shutter is in the extreme rear position, and the uncoupling protrusion 13 of the trigger rod is in the front groove of the shutter, the trigger rod, moving forward, removes the sear from the gear with the trigger (Fig. 3).

- when releasing the shutter, the latter moves under the action of the return spring to the front position. When, when moving forward, the shutter with its extending protrusion 16 ceases to hold the trigger, the trigger starts to rotate after the shutter clockwise (Fig. 4). The rear wall of the front groove of the shutter, recessing the trigger rod, releases the sear from the gear. The sear under the action of its spring unfolds and with its retaining protrusion 14 is pressed to the trigger.

- with the further movement of the shutter forward, the trigger continues to unfold until its safety protrusion 15 reaches the retaining protrusion 14 of the sear 11 (Fig. 1). Thus, the trigger is placed on the safety cock.

To remove the trigger from the safety cock, simply turn the trigger counterclockwise until it stops.

Claims (2)
