ANTI-RAMMER SLIDING GATES Russian patent published in 2019 - IPC E06B3/46 E06B5/10 E06B11/02 

FIELD: construction.

SUBSTANCE: invention relates to devices, in particular, to antirammer sliding gates intended for creation of physical obstacle at attempt of unauthorized entry of vehicles into territory or exit from territory of protected objects of any significance class. Structure of gate leaf is made in form of truss. Steel sheets are filling the gate leaf. Along the entire length to the lower belt of the truss there is a guide of the open U-shaped section, as well as a rack, which is driven by a gear installed on the output shaft of the gate leaf drive. Said flap has four attachment points. Two roller supports and two pairs of guide rollers. In the lower part of the flap there is a steel beam of box section. On one end of the beam there is a rod, and on the other end there is a sleeve. Along the entire length inside the beam, around the sleeve and rod, is wound in several turns of steel rope, forming a closed system. On one of gate posts there is a support, to which, in its turn, bolt drive and bolt is fixed. Movable part of the latch locking the gate leaf in the closed position is a deadbolt. Gate posts are spatial metal structures rigidly fixed on foundation, having vertical groove along their entire height to fix flap from plane under action of transverse load.

EFFECT: expansion of operational properties, reduction of material consumption and increase of concealment of one of the main power elements ensuring strength of the device.
