DEVICE FOR PROTECTION OF WINDOW OF VEHICLE Russian patent published in 2018 - IPC F41H5/26 

FIELD: transportation.

SUBSTANCE: device is attached from the outside in front of the window opening of the vehicle and contains a screen in the form of a rectangular armoured frame and a drive. Two armour plates are placed in one plane in the frame with the possibility of reciprocating motion, forming a narrow viewing slot along the line of the closing of the inner ends. In rectangular recesses, rollers-pushers are mounted. The outer ends of the armour plates are constantly abutted against the helical springs of the beams of the frame. The armour plate drive contains two electric motors, closed by armoured canopies. The ends of the shafts of electric motors are inserted into the frame from two opposite sides, on which the eccentric cams are rigidly mounted. Electric motors are powered via plug-in connectors, a speed regulator, an indicator light, a fuse and a switch. The socks of cams-eccentrics consistently transmit forces to the pushers-pushers of one or another armoured sheet. The height of the observation slot increases periodically to the height of the cam of the eccentric cam.

EFFECT: improved visibility through the observation slot.
