Description

The invention relates to the field of small arms, in particular to the class of hunting weapons having a top ventilated bar for aiming.

In order to increase the effectiveness of the use of small arms equipped with optical sights.

Currently, for mounting sights to weapons, in most cases, are used trunks such as "Dovetail", "Picatirmy", "Weaver", which are installed on the receiver or made directly on it. Accordingly, the optical sights have the same mount. In our country and neighboring countries, the most popular hunting rifles are the MP-27 (IZH-27), MP-153 brands, manufactured by the Izhevsk Mechanical Plant for more than 4 decades.

Recently, optical collimator sights have appeared on the market for hunting rifles. For accurate aiming, it is enough to aim the arrow and hold on the target a light spot of the reticle formed by a reflector located in the sight window of the sight housing.

The design of the hunting rifle brand IZH-27 and its analogues does not provide for the possibility of installing any sight that increases the effectiveness of its use.

Equipping hunting rifles with a universal device for mounting optical sights, in particular collimator sights, is an urgent and demanded task from consumers (hunters). Several devices are known for mounting optical sights on hunting weapons having an upper ventilated bar. Among them, one can distinguish transition brackets-arms for rifles with vertically and horizontally located trunks manufactured at FSUE "Novosibirsk Instrument-Making Plant" as analogues, shown in FIG. 1, and a transitional mounting plate of the Weaver type, manufactured by the Vologda Optical and Mechanical Plant OJSC, article number: VOMZ-26508, is shown in FIG. 2. In the first case, the ring-shaped loop located in the lower part of the mount covers the forend and trunks. The loop is pulled together by screws and holds a “Dovetail” -type bar located at the top of the mount, on which sights are mounted.

In the second case, the transition U-shaped bar with the Weaver base in the upper part is superimposed on top of the ventilated bar of the weapon and is drawn to it with two screws inserted into the internal grooves of the vented bar. The disadvantages of these devices are:

1. Large dimensions and weight

2. The difficulty of installing on weapons

3. The inability to aim through the mechanical sight without removing the adapter bracket or mounting plate.

Closest to the proposed device, selected as the closest analogue (prototype), is a universal mount, patent for utility model RU 2863 from 09.16.1996

The universal mount device is shown in FIG. 3.

The device comprises a bar with two movable brackets mounted on it, in which an optical sight is mounted. The bar has a U-shape and is mounted on the weapon with three tightening screws that are inserted into the internal grooves of the vented bar. In the upper part of the plank, a Swallow Tail mounting base is made, on which movable transitional brackets or optical sights having a Swallow Tail mounting base can be mounted.

The aim of the present invention is to simplify the design of the device for mounting optical sights on hunting weapons having a top ventilated bar, increasing its operational characteristics, in particular, providing the possibility of aiming through a mechanical sight without removing the adapter bracket, as well as providing the possibility of installing collimator sights having a mounting base of various types: Dovetail, Picatinny, Weaver and other types.

This goal is achieved due to the fact that in the proposed device, in contrast to the prototype, the U-shaped bar is made of two symmetrical brackets - left and right, which are installed on the ventilated bar of the weapon, respectively, on the left side and on the right with the help of tightening brackets of screws passing through internal rectangular grooves of the ventilated strip, while the external contour of the surfaces of the mounted brackets forms the basic contour of the planks of the “Dovetail” or “Picatinny” or “Weaver” type or other type in, the space between the brackets in the upper part remains free, which allows the shooter to aim through a standard mechanical sight without removing the device for mounting optical sights from the weapon, when firing without an aim.

The essence of the claimed device is illustrated in FIG. 4. A device for attaching optical sights with a “Dovetail” type clip on a weapon with an upper ventilated bar, consists of brackets - right 1 and left 2, which are connected to each other by screws 3. Screws are inserted into the holes of the brackets and rectangular grooves of the vented bar guns. The holes in the brackets are located so that when installing the tightening screws, the surface of the screws is in contact with one vertical and two horizontal surfaces of the internal rectangular grooves of the vented bar and, thus, restricts the movement of the brackets in horizontal and vertical directions.

As a limiter for the movement of the brackets in the horizontal and vertical directions in order to increase the reliability of fastening, rectangular bosses 4 can be additionally made in the lower part of the brackets, the flat surfaces of which are in contact with one vertical and horizontal surfaces of the internal rectangular grooves of the vented bar and thus limit the horizontal movement of the brackets and vertical direction. The device is shown in FIG. 5.

When the screws are tightened, the brackets are tightly pressed against the ventilated strip 5 and their external surfaces form the contour of the Swallowtail trims, as shown in FIG. 4, 5, or “Picatinny” and / or “Weaver”, shown in FIG. 6, or other trims on which sights are mounted.

A device for attaching optical sights with a clip of the "Picatinny" and / or "Weaver" type as an assembly and on the IZh-27 hunting rifle is shown in FIG. 7. In FIG. Figure 8 shows the "Kid" collimator sight mounted on an IZH-27 hunting rifle using a device that forms the contour of a Swallow Tail bar.

Thus, the proposed device for mounting optical sights mounted on a weapon allows you to aim through a mechanical sight without removing it from the weapon during the entire period of operation, unlike existing devices it is small in size, weight, easy to install on weapons and convenient to operate .

Claims (1)

A device for mounting optical sights on a weapon having a top ventilated bar, consisting of a mounting bar with a dovetail or Picatinny and / or Weaver or other type of mounting base mounted on a ventilated bar of a weapon, characterized in that the device consists of two symmetric brackets, left and right, which are installed on the ventilated bar of the weapon, respectively, on the left and right sides with the help of tightening screws passing through the internal grooves of the vented bar the external contour of the surfaces of the installed brackets forms the contour of the dovetail, or “Picatinny”, and / or “Weaver” or other type of installation base, while the space above the ventilated bar between the brackets remains free, which allows the shooter to aim through a regular mechanical sight without removing the device when firing without a sight.
