Description

 The invention relates to military equipment and is aimed at improving small-sized small arms for conducting both single and automatic firing, in which the store is located in the handle, in particular a submachine gun.

 Submachine guns are widely used for arming the police in almost all countries of the world due to their small mass and overall characteristics, high density of fire and acceptable accuracy and accuracy (submachine guns MP5K - Germany; ultrasound, mini ultrasound - Israel; MP5 A3, MP5 K1 - Germany; Ingram 10, Ingram 13 - USA).

 The weight of such submachine guns is 2 ... 3.5 kg.

 A disadvantage of the known submachine guns is the large mass and lack of reliability.

 The closest analogue of the claimed solution is an automatic small arms, protected by RF patent 2077013, publ. 04/10/97, MKI F 41 A 19/06. This weapon contains a receiver, a bolt frame with a return spring, a bolt and a trigger mechanism, including a hammer with a mainspring, spring-loaded sear and disconnector, a spring-loaded trigger.

 In this case, the sear and disconnector are on the same axis, and the trigger and the self-timer are on the other axis, and these axes are parallel to each other. In addition, the trigger has a protrusion for interacting with the sear.

 The disadvantage of this small arms is that, with its high reliability and simplicity of design, it is not compact enough for close combat, for example, in urban conditions, since the store is located, judging by the available materials, in front of the handle and the trigger, which entails some increasing the length of the sample, as well as not very convenient balancing (the location of the center of gravity outside the fire control handle; the fire mode translator is made as a separate part).

 The technical task of the invention is the creation of a highly reliable, compact and convenient small arms with a magazine in the handle.

 This problem is solved in that the weapon of the design described above has a trigger sleeve pivotally connected to the trigger using additional traction and located on the self-timer axis, the self-timer axis is also used as a translator, which is made with a cutout for interacting with the additional disconnector tooth and at the end which the translator’s flag is set to.

 This embodiment of the weapon allows you to position the store in the handle, improve its balance and reduce dimensions. The weight of this submachine gun is 1.5 ... 1.6 kg.

The invention is illustrated by drawings:
figure 1 - the location of the mobile weapons system before loading, section;
figure 2 is a top view of figure 1 (partial section);
figure 3 - the drummer cocked and held disconnector;
FIG. 4, 5, 6 - the position of the disconnector and the self-timer axis (translator of the fire mode, respectively, with a single fire 4, 5 and automatic fire 6).

 In figure 1, 2, 3, the weapon contains a receiver 1 with a handle 2, a bolt frame 3, a bolt 4, a return spring 5, a hammer 6 and a combat spring 7. The trigger mechanism consists of a trigger sleeve 8 and the trigger 9 itself, connected between a thrust 10, as well as a sear 11, a self-timer 12, a translator 13. On the axis 14, together with the sear 11, there is a disconnector 15 in the form of a two-arm lever. The trigger sleeve 8 and the self-timer 12 are located on the axis 16 parallel to the axis 14. Between the sear 11 and the disconnector 15 there is a spring 17 of the sear and disconnector. On the axis 16 there is a self-timer spring 18 and a trigger sleeve spring 19.

 On the trigger sleeve 8, a protrusion 8a is made for interacting with the sear 11, a protrusion 8b for interacting with the disconnector 15 and a lever 8c with the axis of the sear 11.

 The disconnector 15 represents a two-arm lever, the rear shoulder of which is spring-loaded and serves to hold the hammer 6 in the cocked position with the trigger 9 pressed (Fig. 3). On the front (right in the drawing) shoulder, freely covering the axis 16, an additional tooth 15a is made (Fig. 4), interacting with a cutout 16a on the self-timer axis 16. Axis 16 performs the role of a translator, to change the fire mode at its end there is a flag 13 (figure 2).

 The axis of the 14 sear simultaneously performs the function of a fuse. For this, a fuse box 20 is fixed on it and a cutout 14a is made for passing the lever 8c (Fig. 2).

The weapon works as follows
When moving the movable system back, after setting the fuse lever 20 to the “Fire” position, the shutter 4 is unlocked and the bolt frame 3 releases the self-timer 12, which rests against the receiver 1. When the bolt frame 3 is further retracted, the bolt 4 and firing pin 6. Return 5 and combat 7 springs are compressed.

 When releasing the mobile weapon system, it, together with the shutter 4 and the striker 6, moves forward under the action of the return 5 and combat 7 springs. The shutter pushes the upper cartridge out of the magazine, sends it to the chamber and locks the bore. The drummer stops at the self-timer 12 (figure 3).

 The bolt frame 3, continuing to move forward, with its protrusion unfolds the spring-loaded shoulder of the self-timer 12, which disengages from the hammer 6. The drummer, under the action of the mainspring, moves forward and becomes on the back shoulder of the whispered 11 (or disconnector 15).

 For conducting single firing, it is necessary to set the translator of the firing mode 13 to the position "Single shooting" (figure 4). In this case, the axis 16 is rotated; the cutout 16a is located under the protrusion 15a of the disconnector 15 and does not prevent the latter from turning when the trigger sleeve 8 and its protrusion 8b are rotated (Fig. 5).

 To make a shot, the fuse lever 20 is turned down, while the axis 14 is rotated, a cutout 14a which is located above the end of the lever 8c of the trigger sleeve 8 and does not interfere with its passage when the trigger is pulled. The sear 11 is rotated by the protrusion 8a of the trigger sleeve. A shot is taking place.

 After the shot, with the trigger pulled, the movable system (bolt frame, bolt, hammer) moves to the rear position, extracting the spent sleeve, compressing the fighting 7 and return 5 springs. After impact in the extreme rear position, the mobile system moves forward under the action of the return and mainspring.

 Drummer 6 initially stops at the self-timer 15. When moving forward, the shutter pushes the cartridge out of the magazine, sends it to the chamber and locks the bore.

 The bolt frame 3, while continuing to move forward, rotates the self-timer 15 with its protrusion, the shoulder of which disengages from the hammer 6. The hammer, under the action of the mainspring 7, moves forward and stands on the back shoulder of the disconnector 15 (with the trigger pulled) (Fig. 3).

 After releasing the trigger and turning the trigger sleeve 8, the disconnector 15 will turn due to the interaction of its bend and the protrusion of the sleeve 8, the hammer 6 will move forward and stop on the back shoulder of the whispered 11. For the shot to be fired, press the trigger again.

 To conduct automatic firing, you must put the translator of the shooting mode 13 in the "Automatic shooting" position (Fig.6), while the axis 16 is rotated and the bottom of the cutout 16a is located under the protrusion 15a of the disconnector 15, excluding the rotation of the disconnector.

 When you press the trigger 9, the protrusion 8a of the trigger sleeve acts on the front shoulder of the sear 11, which will turn and release the hammer 6. A shot will be fired. Further, everything happens, as in single shooting. But after the bolt frame 3 rotates the self-timer 15, the hammer 6 under the action of the mainspring 7 will strike the cartridge capsule. A shot will happen. Shooting will be repeated until the trigger is pressed and there are ammunition in the magazine. After releasing the trigger and turning the trigger sleeve 8, the sear 11 will turn under the action of the spring 17 and the drummer 6 will stop on the rear shoulder of the sear. When you press the trigger again (if there are cartridges in the magazine), the above automatic firing process will be repeated.
