Abstract

The revolver has a cylinder (3) with chambers with longitudinal ribs, preventing loading of full-bore rigid bullets. The barrel has a generally cylindrical bore (25) with movable internal fins (4-6) just inside the muzzle and a larger internal fin (24) near the firing chamber end to prevent the passage of a rigid bullet.

Description

This utility model relates to firearms for firing deformable bullets, in particular rubber bullets, according to the restrictive part of claim 1 of the formula.

Firearms of the kind described above are well known. Problems often arise due to legislative requirements prohibiting the firing of such firearms with undeformable bullets, in particular metal bullets. In particular, legislative provisions prohibit firing of bullets with a diameter larger than a given diameter. For example, in Russia there is a regulation according to which firearms are allowed for free sale only when they are not intended for firing with metal bullets with a diameter of 4 mm or more.

In addition, there is a legislative requirement in Russia, according to which firearms are allowed for free sale only when deformable bullets can be fired from it using standard cartridges with an energy density of less than 0.5 J / mm. For this purpose, for example, a lead bullet is placed in firearms in different places and a shot is fired. In this way and this test, firing of non-deformable bullets larger than a predetermined size should be prevented.

The task underlying the utility model is to create firearms of the kind described above, which provides shooting with deformable bullets larger than a given diameter and at the same time significantly prevents the shooting of non-deformable bullets larger than a given diameter or shooting with non-deformable bullets with too high energy.

According to the utility model, this is achieved by means of a firearm with the hallmarks of claim 1. Dependent clauses relate to preferred enhancements.

The means for limiting the cross-section can, for example, have a width in the light of less than 4 mm in the first direction perpendicular to the direction of the bullet’s light, and in the second direction different from it, perpendicular to the direction of the bullet’s movement — much wider in the light. Thanks to this implementation through means

sectional restrictions can pass a rubber bullet, for example, circular cross-section 6-10 mm, and it is accordingly deformed. After passing through the means of restricting the cross section, the deformable bullet regains its original shape and leaves the weapon through the barrel.

A non-deformable or solid bullet, in particular a metal bullet whose diameter is greater than the width in the light in the first direction, can neither pass through the means of limiting the cross-section, nor destroy or damage them when passing through. Thus, it can subsequently be established that no undeformable or solid bullet was fired from these weapons.

Further, between the starting position and the barrel can be provided with an additional indicator, made, for example, in the form of a ring. This indicator may be damaged by non-deformable or solid bullets smaller than the specified diameter. Damage occurs, in particular, on the basis of the scattering action after passing through the means of limiting the cross section. You can also use this indicator to determine whether a firearm, according to the invention, was fired from an undeformable bullet instead of a deformable one.

According to one preferred embodiment of the present invention, the firearm does not have a barrel between the means for restricting the cross-section and the barrel, and the bullet between the means for restricting the cross-section and the barrel can move mainly non-directionally, and this space for the movement of the bullet is surrounded, in particular, mainly unstructured, similar to a pipe body. In particular, the Russian law on weapons prescribes that firearms are allowed for free sale only when they do not have a barrel in which a bullet can be fired. Due to the unstructured, similar to the pipe of the body, not conducive to maintaining a bullet, this requirement can be observed.

In one preferred embodiment, it may be provided that the means for restricting the cross section have a narrowing in the chamber of the drum. Such a narrowing eliminates the possibility of firing non-deformable bullets larger than a given size.

Alternatively, or in addition to this, it may be provided that the means for restricting the cross section comprise at least one locking element protruding in the path of the bullet. Also, this locking element can exclude the possibility of firing non-deformable bullets larger than a given size.

It is possible to make at least one ventilation slot in the barrel of a firearm to remove powder gases. Due to this, it is possible to reduce the pressure acting on the deformable bullet.

It is possible that the means for restricting the cross section contain several locking elements protruding in the path of the bullet from more than one side. Due to the fact that the means for restricting the cross section contain locking elements protruding in the path of the bullet or into the barrel on more than one side, in particular due to the fact that the locking elements are located mainly symmetrically to the axis of the barrel, the flight path of the bullet leaving the barrel is stabilized or oriented approximately parallel to the axis of the barrel.

It is preferable to place the locking elements in the direction of fire almost in front of the barrel. Shortly before exiting the barrel, this has a positive effect on the movement of the bullet.

It is advisable that the means of restricting the cross section contain at least one additional locking element protruding in the path of the bullet and located in the direction of fire almost in front of the locking elements from the muzzle. This additional locking element can be optimized to prevent firing of non-deformable bullets. When firing a non-deformable bullet, the locking elements from the muzzle side can adjust the direction of movement of the bullet after moving past the additional locking element.

The firearm depicted in Fig. 1, according to a utility model, made in the form of a revolver, made with the possibility of firing a bullet (not shown) from the initial position in the drum zone 3. The firearm further comprises sectional limiting means made in the form of an insert 2, which are located in the direction of the shot behind the drum 3. Alternatively or additionally, it is possible to arrange means for restricting the cross-section or additional means for restricting the cross-section in the drum 3, in particular one means of limiting the cross section per channel of the drum 3.

As can be seen from figure 2, the insert 2 is fixed in a firearm, for example, by means of a transverse pin 4.

Insert 2 is shown in more detail in FIGS. 3a-3d and 4. Insert 2 consists of two parts 5, 6 shown in FIG. 4 in a state separated from each other. Due to the composite implementation of the insert 2, it is more simple to manufacture. Parts 5, 6 can be interconnected, for example, by screws 7 (figa).

Box 2 has an input side, i.e. on its side turned in the installed state to the firing position 1, the hole 8 is basically a circular cross section of a relatively large width in the light. On the output side, i.e. on its side facing the muzzle, insert 2 has an opening 9 of a substantially oval cross section. This hole 9 has in the direction perpendicular to the direction of movement of the bullet a significantly smaller width in the light than the inlet 8. In particular, the light width of the hole 9 in the said direction is less than the width in the light of the exit holes

drum 3, in particular less than 4 mm. The inner section of the insert 2 is continuously changing from the input side to the output side.

5a-5d show another preferred embodiment of the insert. Also this insert can be composed of two parts. This is not shown in FIGS. 5a-5d. The insert 10 shown in FIG. 5 a has an opening 11 on the input side, which basically corresponds to the hole 8. On the output side, the insert 10 has an opening 12, mainly of a cross-shaped contour with rounded ends. In particular, the hole 12 is formed by the middle section 13 of the section and four crosswise adjoining semicircular sections 14 of the section. Moreover, in particular, the diameter of the middle section 13 of the section, as well as each of the diameters of the semicircular sections 14 of the section, is less than 4 mm. The inner section of the insert 10, like the insert 2 in FIGS. 3a-3d, basically continuously changes from the input side to the output side.

The insert 15 shown in FIGS. 6a-6d can also be composed of two parts, although this is not shown. The insert 15 has an opening 16 on the input side, which basically corresponds to the hole 8. The hole 17 of the insert 15 on the output side is generally star-shaped. In particular, the hole 17 on the output side has a middle section 18 of the cross section and six external sections of the cross section adjacent to it and extending from it outward from it, mainly a rectangular contour with rounded corners. Moreover, in particular, the diameter of the middle section 18 of the cross section is less than 4 mm. Further, the light width of the outer sections of the section 19 in the radial direction or in the direction perpendicular to it is less than 4 mm.

The internal section of the insert 15 changes similarly to the inserts 2 and 10, mainly continuously from the input side to the output side.

Figure 1 also shows that in the direction of movement of the bullet behind the insert 2, the body of the firearm 20 is made not in the form of a barrel, but in the form of a shirt, which serves only as a guide for the frame when the firearm is made in the form of a gun.

In this housing 20 located in the direction of the bullet’s movement behind the insert 2, a ring 21 protruding slightly backward from it is installed, which serves as an indicator. If instead of the provided rubber bullets, solid bullets, for example metal shot, are used, then these solid bullets, after passing through insert 2, will leave it from the output side partially at significant angles to the average direction of propagation, so that the solid bullets will fall onto ring 21 and damage it. Thus, it can subsequently be established without any problems whether

firearms according to the invention, firing a forbidden solid bullet.

The firearm depicted in FIGS. 7a-7b, according to a utility model, is designed as a revolver. On figa-7b, the same parts are indicated by the same reference numbers as in figure 1.

The revolver drum 3 in FIG. 7a has chambers 22 provided with a restriction 23. The restriction 23 shown in FIG. 7b is made, in particular, in the form of a one-way narrowing of a cylindrical chamber, for the rest, of the chamber 22.

Due to the narrowing of 23 of the firearms, according to the utility model, only very small undeformable bullets, for example, a very small lead bullet, can be fired in Fig. 7a, so that when shooting with such a lead bullet, relatively many powder gases pass by. For this reason, the maximum energy density imparted to this lead pool is less than 0.5 J / mm ² .

Alternatively, or additionally depicted in FIG. 7a, a preferred embodiment of a firearm according to the invention may comprise a locking element 24 in the barrel 25. This locking element 24 is made, for example, in the form of a locking plate directed from one side into the barrel. Also, this locking element 24 eliminates the possibility of firing through the barrel 25 with large undeformable bullets.

The firearm depicted in Fig. 8, according to a utility model, is made in the form of a pistol. In Fig. 8, the same details are also indicated by the same reference numbers as in Figs. 7a and 1 of Fig. 1.

Also, the preferred embodiment depicted in FIG. 8 has locking elements 24 directed into the barrel 25, which can also be made in the form of locking plates directed into the barrel 25. In the embodiment of FIG. 8, two stop elements 24 are arranged in the direction of fire, one after the other and at a distance from each other, which are directed into the barrel from opposite sides. You can also perform only one locking element 24 or more than two locking elements 24. Further, it is possible to provide, for example, one locking element 24, passing through large sections of the barrel 25.

In the preferred embodiments of FIGS. 7a and 8, it is possible to make one or more ventilation slots in the barrel 25 that remove powder gases to reduce pressure. Ventilation slots are made in the form of longitudinal slots.

The embodiment of the firearm depicted in FIGS. 9 and 10, according to the utility model, is similar to that shown in FIG. 7 and also contains a stop

element 24. In addition to the locking element 24, the firearm contains three locking elements 27, 28, 29, almost in front of the muzzle, directed into the barrel 25 radially from different sides. These locking elements 27, 28, 29 are not as large as the locking element 24, however, they can correct the movement of the bullet so that it leaves the barrel 25 parallel to the longitudinal direction of the barrel or its axis 26. The locking elements 27, 28, 29 are located at an equal angular distance in relation to each other and, thus, symmetrically to the axis 26 of the barrel.

It is possible to provide more or less than three locking elements 27, 28, 29 directed towards each other.
