Definitions

  • 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 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.
  • 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. 2 - the fuse is on (installation option on the right side);
  • FIG. 3 is a view along arrow A in FIG. 2;
  • FIG. 5 is a view along arrow B in FIG. 4;
  • FIG. 6 - the fuse is on (installation option on the left side);
  • FIG. 8 is a view along arrow B in FIG. 7;
  • FIG. 9 is a cross-section BB in FIG. 7;
  • Figure 10 is a cross section GG in Figure 7;
  • 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.
  • 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.
  • FIG. 2-3 presses on the protruding end of the fuse on the left side until it is drowned in the weapon body.
  • 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.
  • 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.

Abstract

L'invention concerne des armes à feu de petit calibre et peut s'utiliser dans des armes réalisés selon la configuration « bullpup ». Le mécanisme de l'invention comprend une détente comportant une saillie de sécurité qui interagit avec la saillie de verrouillage de la sécurité. La sécurité comporte un arrêtoir qui la fixe dans les positions « active » et « inactive ». La saillie de sécurité de la détente est disposée devant cette dernière et plus haut que son axe de rotation. La sécurité se présente comme un « curseur transversal » qui est situé devant la détente et qui est symétrique aux axes de symétrie. La saillie de verrouillage de la sécurité est formée par le découpage dans le curseur transversal de deux rainures ouvrées qui forment des zones adjacentes. La rainure ouvrée formant la première zone est obtenue par le découpage de trois secteurs (de 90° chacun), et la rainure ouvrée formant la deuxième zone est formée par le découpage de deux secteurs (de 90° chacun) opposés; un des secteurs de la deuxième zone constitue un prolongement du secteur de la première zone. L'invention permet d'améliorer la fiabilité et d'améliorer les conditions d'utilisation de l'arme.
