Description

The utility model relates to the field of armored vehicles and is intended to protect against attack and defensive fire from small arms from the inside of an armored vehicle.

Known loophole containing a housing made of guides and linings, between which there is a flap with the ability to move, the guides are interconnected by two cross members, forming a window overlapped by the flap, and in one of them there is a rod for the return spring interacting with a stop rigidly fixed on the shutter, in addition, in one of the guides and pads of the housing, holes are coaxially made, in which the lock and its shank with a spring located on it are respectively installed, and which is worn on top with a button connected to the clamp shank by an axis, and the transition from the clamp diameter to the shank diameter is made in the form of a cone with a leg height of at least 1/2 of the flap thickness, while a notch interacting with the clamp is made in the flap (RU No. 38921, IPC F41H 5/26 (2000.01), published on July 10, 2004).

Known loophole containing a flap, a flap drive mechanism, a flap lock, a loophole body made in the form of a bulletproof sheet in which there is a window for firing and a figured hole for the flap axis lock located in the lower part of the pivot axis, the flap drive mechanism being located under the rotation handle, and the flap in the open position has a stop, the height of which is more than the axial stroke of the rotation handle (RU No. 82310, IPC F41H 5/00 (2006.01), published on 04/20/2009).

Also known is a loophole installed in an aperture of bulletproof glass, comprising a body with an opening for firing, a damper providing the ability to close and open a hole for firing, and a device for moving the damper, while the body of the loophole is made in the form of a single part installed in the hole bulletproof glass with a gap filled with an adhesive that secures the loophole body to the bulletproof glass, in addition, from the side of a possible attack along the perimeter of the loophole body ix, greater than the size of the hole in the bulletproof glass, which is also glued to the armored glass through an adhesive (RU №77408, IPC F41H 5/26 (2006.01), publ. 20.10.2008).

Also known, chosen as the closest analogue, is a hidden type loophole mounted on a car body containing a body with a hole, a damper with an actuator made in the form of a spring mounted on an axis, while the body of the loophole contains armor plates located perpendicular to the plane of the body from the side opening the damper and rigidly attached to the body, and the loophole is installed between the body armor and the car body and has a completely hidden location (RU No. 2587132, IPC F41H 5/26 (2006.01), published on 06/10/2016).

The known design of the loophole has insufficiently high performance characteristics, namely such indicators as reliability and ease of maintenance.

The task to which the claimed technical solution is directed is to improve the operational characteristics of the loophole by increasing its reliability and ease of maintenance.

To solve the problem, a loophole for small arms, containing an armored body made in the form of a frame, an armored hatch mounted on an axis with the possibility of folding outward, further comprises an armored viewing window mounted in an armored body, an opening-closing mechanism for the armored hatch, containing an internal rotary hatch a handle having a cam fixed on the axis end, interacting in a closed state with a fixing loop of the armored hatch, and a handrail, while the armor axis annogo hatch is secured in the loops with holes for fastening to the vehicle body.

The set of distinctive features, namely, that the device further comprises an armored viewing window installed in an armored housing, an opening-closing mechanism for the armored hatch, containing an internal rotary handle having a cam on the axis fixed to the axis, which interacts when closed with the armor hatch fixation loop , and a handrail, while the axis of the armored hatch is fixed in loops having holes for attachment to the vehicle body, allows you to increase over zhnosti and serviceability loopholes, thereby improving its performance, provide an opportunity to fire in all directions from the armored vehicle being protected.

An analysis of the known technical solutions, carried out on the basis of scientific, technical and patent documentation, showed that the set of essential features of the claimed technical solution is not known from the prior art, which suggests that it meets the patentability condition of the novelty utility model.

The claimed technical solution is illustrated by the drawings:

FIG. 1 - loophole for small arms, inside view of the vehicle;

FIG. 2 is the same view from the outside of the vehicle;

FIG. 3 - the same side view;

FIG. 4 - same, side view with open loophole of the loophole. The loophole 1 for small arms is made of armored steel, designed for firing from various types of small arms and contains an armored viewing window 2 for observation, including when firing.

The loophole 1 is equipped with an armored hatch 3 mounted on the axis 4 with the possibility of folding out. The opening-closing mechanism of the armored hatch contains an internal rotary handle 5, having a cam 7 fixed on the axis 6 of the end, interacting in a closed state with a loop 8 for fixing the armored hatch, and a handrail 9. The axis 4 of the armored hatch is made in the form of a torsion bar, is fixed outside in loops 10 having holes 11 for attachment to the vehicle body.

The body 12 of the loophole consists of the outer part 13, made in the form of a frame into which the viewing window 2 is inserted, and the inner part 14, which has two openings in the places for the viewing window and the loophole, on which the rotary handle 5 is fixed on the axis 6.

To ensure the tightness of the closed loophole, it is equipped with a seal 15. To quench the shock forces, rubber buffers 16 are mounted on the vehicle at the locations of the hatch.

To open the loophole's hatch, carefully turn the handle 5 clockwise until it stops to the position opposite the “OPEN.” Plate, holding the hatch by the handrail 9.

To close and fix the hatch 3, it is necessary to lift the handrail 9, pulling it inward as much as possible and turn the handle 5 counterclockwise to the stop in the position opposite the plate “CLOSED.”

The center of gravity of the hatch 3 is moved away from the axis of the hinges 10, which helps to facilitate its opening under the weight of its own weight.

The claimed technical solution allows to improve the operational characteristics of the loophole for small arms.

The inventive loophole for small arms meets the requirements of industrial applicability and its manufacture is possible on standard processing equipment.
