Description

The utility model relates to military equipment, namely to means of protection of sighting devices from damage by bullets and fragments used on self-propelled armored vehicles.

A device 1 is known in which the protection of sighting devices is carried out by lowering them in the stowed position inside the body of the armored object. The disadvantages of this technical solution should recognize the complicated design of the mounting of sights and the poor accuracy of fixing the movable base of the devices in the working position.

Also known is body armor 2 of fixed sighting devices fixed on the body, which is the closest analogue of the claimed utility model. The device contains a protective armored housing with a viewing window and an armored cover. The overview window opens and closes by turning the armored cover, which is driven by a multi-link linkage mechanism, while the path of the armored cover is due to its contact with the copier of the sickle-shaped profile. The closest analogue has the following disadvantages. In the operating position (with the viewing window open), the armored cover is located in front of the protective case window. This leads to partial shading.

or even overlapping the field of view, increasing the dimensions of the device.

The technical result of the claimed utility model consists in eliminating the obscuration of the field of view of sighting devices and in improving

protective properties while reducing size in the working position.

The essence of the claimed utility model lies in the fact that in the armor protection of sighting devices containing a protective case with a viewing window, a rotary armored cover, mechanisms for opening the armored covers and a drive, each mechanism for opening the armored covers contains a rotatable housing and a crank with a pin mounted on the axis of rotation of the armored cover. In the rotary housing with the possibility of reciprocating movement, a slider connected to the armored cover is located. The crank pin enters the transverse closed groove of the slider. There is an emphasis on the slider restricting the mutual rotation of the rotary housing and the crank.

In addition, armored protection of sighting devices is proposed, which is characterized along with the aforementioned features by the fact that an elastic element is positioned coaxially with the slider between the armored cover and the end face of the rotary housing.

In addition, an armored protection is proposed, characterized by the above features, in which the armored cover is connected to the slider by means of an articulated support displaced relative to the longitudinal axis of the slider, and is fixed relative to the slider by a cam fixed to the armored cover and in contact with the elastic element.

In addition, armor protection is proposed, characterized by the above features, in which, in the closed position of the armored cover, the crank pin is fixed by the transverse closed groove of the slider at the dead point of the slider's trajectory.

The inventive utility model is illustrated by graphic materials, where in FIG. 1 shows a diagram of the armor protection of sighting devices in the closed (traveling) position, in FIG. 2 is a projection of FIG. 1, in FIG. 3 shows a diagram of a device in an intermediate position when opening an armored cover; FIG. 4 is a projection of FIG. 3, in FIG. 5 is a diagram of the device in the open (working) position, in FIG. 6 is a projection of FIG. 5.

Armor protection of sights has the following design. On the surface of the body of the armored object 1 there is a protective case 2 with a window 3. Inside the protective case with the ability to view the terrain through the viewing window, sights are placed 4. On the protective case with the ability to close the viewing window is an armored cover 5, rotatable around axis 6. Mechanisms are placed on the sides of the armored cover opening, as a rule, two. Each

of the mechanisms for opening the armored cover contains a rotary housing 7 mounted on the axis of rotation of the armored cover 6 and a crank 8 with a pin 9. In the rotary housing, a slider 10 is arranged for reciprocating movement, connected to the armored cover. The drive 11 is connected to the crank 8. The pin 9 of the crank enters the transverse closed groove 12 of the slider. Between the armored cover and the end face of the rotary housing, an elastic element 13, for example, a coil spring, is arranged coaxially with the slider. There is emphasis on the slider

14, restricting the mutual rotation of the rotary housing and the crank. The armor plate is connected to the slider by means of a hinged support

15, offset relative to the longitudinal axis of the slider, and fixed relative to the slider with a cam 16, mounted on an armored cover and in contact with the elastic element 13. The crank pin is fixed by a transverse closed groove of the slider at the dead point of the slider's trajectory.

The device operates as follows. When the crank 8 is rotated from the actuator 11 from the closed position of the armored cover 5, the pin 9 is rotated relative to the rotary housing 7 (Figs. 3 and 4). At the same time, the slider 10 translationally moves inside the rotary housing and pushes the armored cover away from the surface of the body of the armored object 1. When restricting the movement of the slider relative to the rotary body with an emphasis 14, the crank rotates the rotary housing until the armored cover touches the surface of the armored object. During this rotation, the armored cover is kept from rotating relative to the hinge support 15 at the end of the slider with a cam 16 in contact with the elastic element 13. When the armored object touches the body surface of the armored object, the armor cover is rotated relative to the slider on the hinged support when the rotary housing is further turned.

15. When closing the armored cover, the latter returns to its original position relative to the slide under the action of an elastic element.

In the proposed device, with the window open, the armored cover is located behind the rear wall of the protective case, which allows in the working position to eliminate the shadowing of the field of view of sighting devices, to strengthen the protection of sighting devices from the back and reduce the size of the armor protection.
