Description

The invention relates to a short-barreled automatic small arms.

Traditionally, a pistol frame (frame) serves as the basis for the assembly and functioning of parts and mechanisms of short-barreled firearms (pistols and revolvers). The frame is assigned to the class of the main parts of the weapon due to the impossibility, in its absence, not only to ensure the functioning of a short-barreled firearm, but also to assemble it as such. In almost all cases, the pistol frame was a single all-milled steel (or aluminum or titanium alloy) part in which guides were made for the movement of moving parts (bolt and barrel), or structural elements for fastening the barrel and guides for the bolt movement, as well as structural elements (holes, grooves, partitions, etc.) for placing and fixing other parts and mechanisms of short-barreled firearms. The use of new structural materials (such as polymers) in the design of a short-barreled firearm did not fundamentally change the situation and the pistol frame began to be a monolithic part representing a combination of several structural materials, most often cast from a polymer (in particular, glass-filled polyamide) in which they were filled without the possibility disassembly of steel embedded structural elements into their constituent elements (guides of the movable system, etc.). Known family of pistols "Glock" (see, for example: https://modernfirearms.net/ru/pistolety-i-revolvery/pistolety/avstrija-pistolety/glock/), in which the frame is a plastic part in which the guides moving systems, which are a single unit with a polyamide base, which forms the elements of holding the weapon in the hand and is the basis for assembling the remaining mechanisms of the weapon (feed mechanism, trigger, etc.).

The guides of the movable system are made non-removable in a polyamide casing and cannot be separated from the frame.

Known pistol (IT2004MI02167, RU 2005134943 A), containing a frame, a frame, a plug-in case on which at least some elements of the firing mechanism (USM) are installed, and the specified case is inserted into the transverse cavity of the frame and means for fixing the frame inside the frame ... The specified body forms a structure independent of the pistol frame and holds the entire trigger mechanism (USM), with the exception of the trigger and the connecting lever extending from the trigger. In this case, the guides for the movement of the movable system are located on different parts.

Known pistol design (DE 29924790 U1 and US 6260301 B1), consisting of a plastic handle, a trigger housing with guides and trigger parts, including a trigger and a trigger rod, and a bolt with a barrel assembly, moving relative to the handle and trigger housing in the longitudinal direction. The connection between the handle and the trigger housing is made using a rotary axis with a tide, which serves for disassembly and is also the axis of a one-way slide delay, and using a figured groove in the trigger housing interacting with the axis in the handle.

This scheme, chosen as a prototype, has a number of disadvantages, such as a technologically complex and high-precision manufacturing multifunctional part - the trigger housing on which the trigger is fixed, a one-way slide delay fixed on the axis, the trigger rod swinging relative to the trigger, the sear latch , having the ability to move in the longitudinal direction in the grooves relative to the trigger housing. This design, in view of the fact that it contains all the details of the trigger (the complete kinematic chain from the trigger as the details of the perceiving the command action of the firing finger to the final detail of the kinematic chain - the sear latch holding the firing pin on the cocked before firing), must be performed with high accuracy the interposition of the axes for fastening the parts of the trigger. It is also required to perform with high precision a groove in the tide of the trigger body (in height and width) to fix it in the plastic handle, otherwise either the pistol assembly will be impossible, or there will be a backlash of the trigger body relative to the handle, which will negatively affect the accuracy and accuracy shooting, as well as on the resource of this pistol. The axis, which is a pivoting lever for disassembling the pistol, does not allow the slide delay of the pistol grip, either double-sided or thrown to either side, which creates inconvenience in the operation of the pistol for left-handed people. The barrel in this design is movable, which makes it necessary to do, in order to ensure its movement and fixation in extreme positions, guiding and locating surfaces that require high manufacturing accuracy and ensure low surface roughness. Also, the movable barrel worsens the reliability of the operation of the sending mechanism, since the position of the barrel relative to the trigger body and, therefore, relative to the magazine with cartridges will not be uniform from shot to shot, thus, the reliability of the process of sending the cartridge into the chamber is not guaranteed already at the concept level, regardless of specific design. Also, the movable barrel negatively affects the accuracy and accuracy of fire, since its position before each shot will be different each time and it also starts to move immediately after the powder charge ignites and the pressure increases while the bullet is still moving along the barrel bore, which also reduces the accuracy of fire.

The objective of the invention is to eliminate the above disadvantages of the prototype.

The specified problem is solved by a pistol containing a handle (preferably plastic), a housing for accommodating elements of the firing mechanism with guides for the bolt, barrel, bolt, slide delay, sear, trigger, trigger rod, slide delay axis, in which, according to the proposal, a trigger with a mainspring is placed and positioned in the body, a sear with a sear spring, and a trigger with a spring and a trigger rod are placed and positioned in the handle.

To fix the housing for placing the elements of the firing mechanism in the handle, the slide stop axis and the housing fixation pin are used.

On the cylindrical axis of the slide delay, a two-way slide delay is installed with control elements on both sides of the handle.

The barrel is fixedly mounted on the body to accommodate the elements of the firing mechanism using pins.

Also, to fix the body for placing the elements of the firing mechanism in the handle, it is advisable (for reliability) to use an additional fuse axis.

The invention is illustrated by drawings.

FIG. 1 shows a pistol, side view, longitudinal section.

FIG. 2 shows the pistol, side view.

FIG. 3 shows, in part, an explosion diagram: the handle, the body, the trigger and the trigger, the trigger and sear.

FIG. 4 shows callout A in side view.

FIG. 5 shows the implementation and installation of the gate delay.

FIG. 6 shows callout B in a side view.

FIG. 7 shows the fixation of the housing for accommodating the elements of the firing mechanism in the handle additionally by means of the fuse shaft.

To eliminate the shortcomings of this prototype, a pistol design is proposed, containing a (plastic) handle 1, a housing 4 for accommodating the elements of the firing mechanism with guides for the bolt, barrel 2, bolt 3, slide delay 9, sear 8, trigger 5, trigger 6 , slide stop axis 10.

In case 4, not all parts of the trigger are placed and positioned as in the case of the prototype (including the trigger and the trigger), but only the trigger 7 with a mainspring, 8 searched with a sear spring. For these parts, mutual positioning accuracy is important. The rest of the details of the kinematic chain of the firing mechanism (trigger 5 with a spring, trigger 6) are placed and positioned in the handle 1.

For the correct interaction of the trigger 6 with the trigger 7 and the sear 8, it is necessary to maintain only two dimensions of the overlap of the parts with each other T and H (Fig. 4), which critically depend on the dimensions S and D (the relative position of the axes of the sear 8 and the trigger 7), and the axis , determined by the dimensions S and D, are made in one part - the body 4, and the position of the trigger rod 6 located in the handle 1 is constant due to the action of the trigger spring 5. Thus, the required kinematic accuracy of the trigger chain is maintained, as in the design prototype, but this simplifies and reduces the cost of the body part 4, and the addition of additional reference holes in the plastic handle 1 practically does not affect the cost of its manufacture, since its shapes and elements are determined by the design of the mold.

Also, to reduce the cost and reduce the likelihood of a technological defect, another method of fixing the housing 4 in the handle 1 is proposed. In particular, the slide stop axis 10 and the pin 11 are used. The use of a locating scheme on two holes / pins makes it possible to simplify the design of the case 4 and increase the accuracy of locating the case 4 relative to handle 1, due to technological capabilities to process a cylindrical hole more accurately than a rectangular groove. Also, the fixation in the longitudinal direction of the housing 4 on the handle 1 is more reliable due to the two supporting surfaces of the pin 11 and the axis of the shutter delay 10, while in the prototype in the longitudinal direction the housing fixes only one axis.

For the convenience of using the pistol, it is proposed to use a double-sided slide delay 9. In the prototype, this design is impossible due to the fact that the fixation axis of the trigger housing is a pivot lever for disassembling the pistol, on one side of which there is a slide delay, and on the other side a tide through which the axis is rotated. It is proposed to install a double-sided shutter delay 9 on the cylindrical axis of the slide stop 10, which has control elements on both sides of the handle 1. Thus, the problem of the possibility of comfortable use of the pistol by both right-handers and left-handers is solved.

The barrel 2 is fixed to the body 4 by means of pins 12. This design solution improves the accuracy of the pistol firing, and also increases the reliability of sending the cartridge into the chamber due to the constancy of the position of the barrel 2 relative to the body 4, since the surfaces for chambering the cartridge into the chamber on modern pistols are made as on the trigger housing and on the barrel (pos. 13 and 14 in Fig. 6).

For fixing the housing 4 in the handle 1, the fuse axis 15 can also be used (Fig. 7). To fix the fuse shaft in the handle 1, use the left 17 and right 16 fuse flags.

In general, the claimed design of the pistol allows achieving at least the following result:

- design simplification;

- reducing the likelihood of technological defects;

- ease of use of the pistol for both right-handed and left-handed people;

- increasing the accuracy of fire.
