RU82310U1 - LOOPHOLE - Google Patents

Abstract

The loophole belongs to the field of production of armored vehicles and is intended to protect against attack and defensive fire from small arms from inside the interior of an armored vehicle. The purpose of the presented utility model is to make the design of the loophole less labor intensive in manufacturing, having a minimum thickness and reliable in operation. This goal is achieved in that the case 2 of the loophole 1 is made in the form of a sheet of armored steel, in which a window 3 for firing and a figured hole 4 for the latch 5 of the axis of rotation of the shutter 6, located in the lower part of the axis of rotation, is located, the drive mechanism of the shutter 10 under the rotary handle 8, and the shutter 7 in the open position has a stop 9, the height of which is more than the axial stroke of the rotary handle 8.

Description

The loophole belongs to the field of production of armored vehicles and is intended to protect against attack and defensive fire from small arms from inside the interior of an armored vehicle.

A known design of the loophole, which includes a frame mounted on the body at the location of the hole for installing the barrel of the weapon, a movable armored plate with a lock of the closed position and the automatic drive to the open position, № (see Appendix 1). However, this design of the loophole is difficult to manufacture and unreliable in operation due to the vulnerability of the damper actuator spring during firing.

The closest technical solution is the design of the patent portal # 75236, containing a housing made of two panels of the armor plate, between which are located the springs of the damper actuator (see Appendix 2). But such a technical solution is laborious, because requires the manufacture of numerous parts for the assembly of the loophole, and the case itself has a thickness that does not always allow the loophole to be placed in places with a minimum distance between the skin and armor.

The purpose of the presented utility model is to make the design of the loophole less labor intensive in manufacturing, having a minimum thickness and reliable in operation.

This goal is achieved by the fact that the loophole body is made in the form of a bulletproof sheet in which there is a window for firing and a figured hole for the latch axis of the flap located in the lower part of the pivot axis, and the flap drive mechanism is located under the rotary handle, and the flap is in openly has a stop, the height of which is more than the axial stroke of the rotation handle

The essence of the technical solution is illustrated by the drawings:

Figure 1 - General view of the loophole;

Figure 2 - Section aa, view of the drive mechanism of the damper.

And presented in the photographs:

On a photo 1 - a loophole, the gate is closed;

On a photo 2 - a loophole, the gate is open;

On a photo 3 - the panel for installation of a loophole.

Appendix 1 and 2 provide an analogue and prototype utility model.

The loophole 1 consists of a housing 2, in which a window 3 is made for firing, a figured hole 4, a retainer 5 (see figure 2) located on the lower part of the axis of rotation of the shutter 6 (see figure 1, 2).

The window 3 is blocked by a shutter 7 equipped with a rotation handle 8. The shutter 7 is held in the closed position by the latch 5, and in the open position it is locked by a stop 9, the height of which is greater than the axial stroke of the rotation handle 8 (see Figs. 1, 2).

Under the rotation handle 8 there is a drive mechanism for the shutter 10, consisting of a rotation axis 6, a spring 11, a guide sleeve 12. The rotation handle 8 itself is connected to the rotation axis 6 using a pin 13 (see figure 2).

The loophole is used as follows: to open window 3, by pressing the handle 8 we remove the latch 5 from the figured hole 4 and, under the action of the spring 11, the shutter 7 rotates automatically until it contacts the stop 9, window 3 is open (see photo 2).

To close the window 3, we act on the rotation handle 8, compressing the spring 11, turning the axis of rotation of the shutter 6, insert the latch 5 into the figured hole 4 until it works, window 3 is closed (see photo 1).

This design can significantly reduce the complexity of manufacturing loopholes, because body parts and flaps are made by laser cutting, it allows you to protect the spring from direct damage by firearms, because such a location of the spring excludes the possibility of its lumbago, and also this design has the smallest thickness, which allows you to install it anywhere in an armored vehicle.
