Description

The invention relates to rail interface systems for hand-held small arms and is intended for attaching additional auxiliary equipment to the weapon.

Currently, the Picatinny rail (https://ru.wikipedia.org/) is widely used as the main strips for attaching additional accessories to small arms (optical and collimator sights, tactical flashlights, laser designators, IR flashlights, rangefinders, etc.) wiki / Picatinny_plane, viewed 02.22.2020) and Weaver bar (https://ru.wikipedia.org/wiki/Waver_plane, viewed 02.22.2020). These strips represent a base on which transverse rectangular cuts are made, the dimensions of which are standardized.

The Picatinny rail and the Weaver rail differ in the width of the slots and the distance between them: if in the Picatinny rail this distance is the same, then in the Weaver rail it can change.

Also widely known is the NATO accessory bar (https://ru.wikipedia.org/wiki/Acceccyapov_HATO_plane, viewed 02.22.2020), which is backward compatible with the Picatinny rail. This bar allows you to use the top edges and side sloped edges for attaching additional equipment.

However, these devices are not suitable for use on compact hand-held small arms such as pistols and revolvers, since they are bulky and difficult to integrate into the design of the weapon. If the Picatinny or Weaver rail is executed according to the military standard, its base in the lower part has a narrow neck of a certain height, which excludes the possibility of direct integration of the rail into the structure of the weapon and allows only adding the bar to the weapon, thereby increasing its overall weight.

When adapting to civilian weapons, the neck of the base of the Picatinny or Weaver rail can be expanded or eliminated altogether, as is done in the design of the Desert Eagle pistol (http://gunsa.ru/desert-eagle-s-udlinennym-stvol-i-integrirovannoj-plankoj -pikatinni.html, viewed 03/01/2020). In this case, the grooves are cut directly on the gun body.

However, in this case, the presence of transverse grooves with right angles leads to their engagement in the fabric of the holster, pockets, bags, etc., which interferes with the rapid extraction of the weapon. In addition, the internal volume of such an adapted strip is insignificant and does not allow to place the necessary parts and mechanisms inside it (parts of the gas outlet mechanism, a return spring with a guide, a barrel, a tube magazine, etc.).

Any of the indicated Picatinny or Weaver strips can be taken as the closest solution to the declared solution.

The technical result of the present invention is to create a compact bar for use on hand-held small arms, which improves the conditions for its operation.

The technical result is achieved by using a bar for weapons, which contains a base having an upper edge, oblique side faces and reverse oblique side faces, while cylindrical slots are made on the oblique side faces.

The execution of cylindrical slots on the inclined side faces of the base of the bar allows you to reduce the height of hand-held small arms at least to the height of the transverse grooves (about 3 mm) of the Picatinny or Weaver rail, thereby reducing the weight of the weapon as a whole. At the same time, such a constructive solution makes it possible to avoid using the right angles of the transverse grooves of the Picatinny or Weaver rail, to exclude the possibility of the grooves catching on the fabric of the holster, bag pockets, etc., thereby simplifying the process of removing hand-held small arms.

Also, in this case, it becomes possible to make the lower part of the base of the bar wider than the width of the upper edge of the base, which allows you to place the necessary parts and weapon mechanisms inside the base of the bar.

The top edge of the plank and backward sloped side faces are required to install additional external equipment on the plank.

FIG. 1 shows a general view of the inventive strip without integration into small arms, FIG. 2 is a view of the inventive strip from above in the longitudinal direction, FIG. 3 is a cross-section of the inventive strip, FIG. 4 is a view of the inventive strip from above in the transverse direction at an angle of 45 degrees, FIG. 5 - the image of the claimed bar on small arms.

The bar for the weapon contains a base 1 of a T-shaped cross-section having upper 2 and lower 3 parts, while the upper part 2 of the base 1 has an upper edge 4 and oblique side edges 5 and 6 with cylindrical slots 7, and the lower part 3 of the base 1 is made wider than its upper part 2 (Figs. 1, 2).

The width of the upper part 2 of the base 1, that is, the distance between the lower extreme points 8 and 9 of the inclined side faces 5 and 6, is 20 ± 0.06 mm. The distance between the upper extreme point 10 of the lateral inclined face 5 and the lower extreme point 9 of the lateral face 6 is 14.5 ± 0.05 mm. The width of the inclined side faces 5 and 6 is 3.4 ± 0.06 mm, the angle of inclination relative to the plane of the upper face 4 of the base 1 is 45 degrees. The lower extreme points 8 and 9 of the inclined side faces 5 and 6 protrude above the narrowed region 11 of the lower part 3 of the base 1 to form reverse oblique side faces 12 and 13, the width of which is 1.9 mm (Fig. 3).

The depth of the cylindrical slots is 1.49 mm. The slots are made with a diameter of 5 mm. The distance between the centers of adjacent cylindrical slots is 10 ± 0.06 mm (Fig. 4).

The claimed bar for weapons can be made as an integral part of the receiver, forend, barrel or frame for weapons. In this case, the use of the bar allows you to get all the advantages: in the presence of a compact design of the bar, it is possible to integrate additional equipment on hand-held small arms, increase the speed of weapon extraction, and place the necessary additional parts and mechanisms inside the base of the bar. In the case of the manufacture of the claimed strip in the form of a separate part of the weapon, all the advantages listed above are retained, with the exception of the possibility of placing parts and mechanisms inside the base of the strip.

Fastening of additional equipment to the declared bar is carried out as follows.

The accessory must have a base with a clip for this strip, as is the case with other known strips. From displacement in the left-right and up-down directions, the additional equipment clamp in the fixed state is pressed against the upper edge 4 and the symmetrical opposite oblique side edges 12 and 13 of the strip. The back-and-forth displacement limits the cylindrical protrusion on the accessory clamp, which fits snugly into one of the corresponding cylindrical grooves 7 of the strip.

The claimed bar for weapons has less weight and reduced dimensions, which generally improve the operating conditions for small arms.
