Abstract

The invention relates to handguns and can be used in guns with a bullpup configuration. The mechanism comprises a trigger with a safety projection for interaction with the locking projection of the safety catch. The safety catch has a stopper which fixes it in the "on" or "off" position. The safety projection of the trigger is situated in front of and above the axis of rotation of the trigger. The safety catch is in the form of a "transverse safety bolt" which is situated in front of the trigger and is symmetrical about the axes of symmetry. The locking projection of the safety catch is formed by cutting two shaped grooves in the transverse safety bolt, which form adjacent sections. The shaped groove that forms the first section is produced by cutting out three quadrants (90° each), and the shaped groove that forms the second section is produced by cutting out two quadrants (90° each) situated opposite each other, wherein one of the quadrants of the second section is a continuation of a quadrant of the first section. The operating reliability and operating condition of the gun are improved.

Description

MANUAL FUSE MANUAL MECHANISM

FIRE WEAPONS A utility model relates to handguns and can be used in weapons with a bullpup layout. The known fuse mechanism is a 5.45mm Kalashnikov assault rifle (manual for a 5.45mm Kalashnikov assault rifle AK 74, AKS 74, AK 74 N, AKS 74 N and 5.45mm Kalashnikov light machine gun RPK 74, RPKS 74, RPK 74 N, RPKS 74 N Moscow , military publishing house in 1984), which contains the trigger (1) with a safety protrusion (8), a fuse (3) with a sector that acts as a locking protrusion and an interpreter, which serves to translate and lock the fuse in the “on” and “off” positions ".

The disadvantages of this device are:

- the ability to control only on the right side of the weapon;

- the inconvenience of switching, especially when wearing gloves;

- a sufficiently large time to turn it off and open fire;

- a loud characteristic click when the fuse is turned off, which is a unmasking factor.

The utility model is based on the task of improving the fuse mechanism by modernizing it, which will improve the service and operational characteristics of the weapon. The task is achieved by modernizing the mechanism of the fuse of a handgun, in which the safety protrusion of the trigger is located in front and above the axis of its rotation.

The fuse itself is made in the form of a "transverse engine", which is located in front of the trigger. The cross section of the fuse slide is symmetrical about the horizontal and vertical axis of symmetry. The locking protrusion has two sections: section A and section B. Section A is formed by cutting three sectors of its cross section, which are limited by the axes of its symmetry. Section B is adjacent to section A, and has, in addition to the same sector as sector A, the sector opposite to it. Sectors in sections A and B may have an area smaller than the total area, but their shape should be symmetrical with respect to the axis of symmetry. The fuse engine can be inserted into its channel on both the right and left sides of the weapon to change the direction of its operation. If a fuse is used in weapons with a bullpup layout equipped with an under-barrel grenade launcher, it can also serve as a fuse for the under-barrel grenade launcher trigger, while the fuse can be installed on either side and there is a blocking function from simultaneously pressing the machine and grenade launcher triggers.

Fig - interaction with the trigger - trigger mechanism grenade launcher (trigger pulled the grenade launcher); Claimed Fuse Mechanism FIG. 2-3, contains a trigger (1), an axis of the trigger (2), a fuse slide (3), a fuse lock (4), a fuse lock spring (5) and a channel to accommodate the fuse (6). The trigger consists of a tail (7), a safety protrusion (8), a hole for the trigger rod (9), a hole for the axis (10) and a hole for lightening the weight and reducing heat transfer (1 1). The fuse box (3) includes sections A and B of FIG. 7-8, which form the locking protrusion (12), the channel for the latch (13), the thrust shoulder (14) and two holes (15) and (16) to facilitate weight.

Channel for fuse placement FIG. 3 includes two eyes, the right (17) and left (18), which have a cylindrical shape with a figured groove (19) cut out in each of them for interaction with the fuse holder (4). Moreover, if the groove of the right eye is facing forward, then the groove of the left eye is 90 ° upward relative to the right. This is due to the fact that the figured grooves, in addition to fixing the fuse, are also intended to prevent spontaneous rotation of the fuse in its channel and to give it the correct position in each of its installation options. The fuse mechanism operates as follows.

To turn on the fuse (right installation option) FIG. 2-3 arrows presses on the protruding end of the fuse on the left side until it is drowned in the weapon body. In this case, the locking protrusion (12) will go under the safety protrusion (8) of the trigger (1), blocking it, and the stopper (4) under the action of its spring (5) will pop over the protrusion of the figured groove (19) on the right eye, thereby fixing fuse in the on state.

To turn off the fuse, it is necessary to press the fuse on the right side to the stop of its stop shoulder (14) Fig. 6 into the body of the weapon. In this case, the locking protrusion of the fuse will come out from under the safety protrusion of the trigger and will release it from blocking. The stopper will jump over the ledge of the figured groove on the back side and fix the fuse in the on state.

When installing a fuse on the left side, the direction of its operation will change by 180 °, and its latch interacts with a figured groove on the left eye of its channel. In the case of using the fuse mechanism together with the firing mechanism of the under-barrel grenade launcher, FIG. 11-12, its trigger (20), which moves along the guides with its rod (21), having a safety protrusion (22) and pivotally connected to the trigger using the axis (23), when the fuse (3) is on, it is blocked locking protrusion (12). When the fuse is off and the trigger of the machine (1) is pressed, the trigger movement of the grenade launcher (20) is blocked by the lowered safety protrusion (8) of the trigger (1). When the trigger of the grenade launcher (20) is pressed, its thrust (21) with its safety protrusion (22) comes under the safety protrusion (8) of the trigger of the machine (1) and blocks it. Due to this property of the mechanism, neither accidental nor deliberate simultaneous pressing of two triggers is possible.

This design of the mechanism can significantly improve the reliability of operation and improve the performance of a sample of automatic weapons in which it will be used.
