Description

 The invention relates to small arms and can be used to create promising submachine guns (PP).

 Known PP [1] designed for automatic or single fire and are widely used in many armies of the world.

 Known PP [2] containing a barrel, a housing with a slot for attaching a magazine and a fire control handle, a bolt with a striker, a return-combat spring and a device for extracting cartridges and a magazine. The disadvantage of this software is the reduced accuracy, which negatively affects the functionality of the software.

 The technical problem solved by this invention is to increase the functional efficiency of PP.

 To do this, the PP is equipped with a spare magazine, the fire control handle is placed in a horizontal plane passing through the axis of the barrel channel, and the body is equipped with a holder or latch for the hand, and the main and spare magazines are installed without communication with each other or are connected by cables. In one embodiment, the fire control handle is located at the rear of the housing and includes a cavity with a plug or channel for attaching a spare magazine. In another embodiment, the fire control handle is located on the side of the housing and is provided with a channel for attaching a spare magazine.

 In Fig.1 shows the appearance of the PP, in Fig.2 a diagram of the action of forces during firing, in Fig.3-5 the process of firing (Fig.3 shutter cocked and held by a sear, Fig.4 whispered retracted by the trigger, the shutter sent the cartridge into the chamber , the firing pin pierced the capsule, Fig. 5 the bullet came out of the barrel, the bolt was thrown back into the cocked position, the sleeve was thrown out), in Fig. 6 PP in the basic version when using the handle as a holder of a spare magazine, in Fig. 7 is a variant of the PP with a remote handle and a retractable hand latch, in Fig. fig. 9; side view of a PP variant with a remote handle in the center and a fixed lock; in Fig. 10, the action of forces when firing for a PP with a remote handle in the center; Fig. 11 is the same when using the magazine as hand retainer, in FIG. 12, 13 a transverse section of the PP with the handle extended and the upper arrangement of the combined sear and trigger.

 PP consists of a housing 1 with an aiming device, a handle 2 and a holder 3; barrel 4 with a chamber, a shutter 5 with a spring 6, a striker, a lever 7 and a device for extracting sleeves; whispered 8 with a spring 9 and a trigger 10 and a magazine 11.

 The shutter 5 contains an opening (recess) for the sear 8, which is connected to the spring 9 and the trigger 10 so that, in the normal position of the hook 10, the whisper 8 is in the opening of the shutter 5, and if the hook 10 is pulled (pressed), it leaves the opening (recess) ), thereby releasing the shutter 5.

 In the basic version of the PP (Fig. 1, 2), the magazine 11 is located at the bottom, the handle 2 is hollow and provided with a plug 12, and the cavity is used to store cleaning accessories, spare parts, etc. In another embodiment (6, 9, 12, 13), the cavity of the handle 2 is used to store a spare magazine 13. At the same time, its upper part can protrude outward, which is convenient for loading the magazine with 13 cartridges. To prevent atmospheric precipitation and land from entering store 13, a hinged cover 14 may be used (FIG. 6).

 One embodiment of the software provides a lateral arrangement of the handle 2. In this case, the magazine 11 can be placed from the bottom, and the housing 1 is provided with a retractable latch 15 for the arrow hands (Figs. 7, 10) or the magazine 11 can dock to the housing 1 side-to-top for fixing the arm (Fig. 8, 9, 11). The remote handle 2 can be placed both opposite the center of mass 16, and in front (behind), and the holder 3 is placed at the same time from the opposite side (Fig. 8). With the remote arrangement of the handle 2, the trigger can be combined with the sear 8 and located on top (Fig.9, 11-13).

 The holder 3 can also be hollow, its cavity, like that of the handle 2, can be equipped with a plug 12 and used to store accessories and spare parts or for a spare magazine 13 and contain a cover 14.

 PP also contains a ramrod 17, which can be mounted under the housing 1 and be connected with the sight of the sighting device and with the pre-crank protrusion of the housing 1 or with the protrusion of the housing 1 for a slot (aiming strip). The main 11 and spare 13 stores can be connected by a cable 18 (carabiner) in the bottom of stores 11, 13.

 In the initial position, the magazine 11 is docked to the housing 1, the shutter is cocked by the lever 7 (spring 6 is compressed), the sear 8 holds the shutter 5 while in its hole (Fig. 3) or indentation (Fig. 12), and the hook 10 is not pressed with the finger arrow . He holds the PP with his right hand on the handle 2, and with the other hand (depending on the variant) for the holder 3 (Figs. 1, 2, 8) or fixes his right hand on the PP with the help of the latch 15 (Figs. 7,10) or a magazine 11 (Fig. 8, 9, 11).

 To open fire, the shooter presses with a finger on the hook 10, pulls it with his index finger (Fig.1-6) or presses it on top with his thumb (Fig. 9, 11-13). In this case, the sear 8 releases the shutter 5, which is thrown forward by the spring 6 (Figs. 4, 13), driving the cartridge from the magazine 11 into the chamber, and pricks its capsule with its striker (Fig. 4). The bullet flies out of the barrel 4, and the gases through the sleeve discard the shutter 5 to its original position (figure 5), compressing the spring 6, the spent sleeve is thus extracted from the housing 1.

 If the shooter continues to push the finger on the hook 1, then the whisper 8 does not hold the bolt 5 and he continues to send cartridges into the chamber, quickly puncture their capsules and provide firing until the magazine 11 is empty. If the shooter releases hook 10, the spring 9 presses the sear 8 to the shutter 5 and, when it moves to the extreme position (Fig. 5), it enters the hole (recess) of the shutter 5, interrupting the shooting.

 When the magazine 11 is empty, it is removed from the housing 1 and replaced by a new magazine 13, which is previously removed from the cartridge pouch, handle 2 or holder 3. The cable 18 prevents the loss of magazines 13, 11. The magazines 11 and 13 connected to each other by the cable 18 can effectively used by the shooter in hand-to-hand combat.

 When using the inventive PP, its functionality is expanded, the accuracy of shooting increases due to the lack of vertical "throwing up" (the line of action of the recoil force practically coincides with the line of action of the force from the reaction of the shooter's hand), the usability is increased, since the PP can be held with one hand, as well as as a spare store always at hand in the handle or holder of the software. Cable-fastened stores can be used effectively in hand-to-hand combat.
