DEVICE FOR VEHICLE RETENTION Russian patent published in 2015 - IPC E01F13/12 

FIELD: construction.

SUBSTANCE: device comprises a flat inertial element installed along the road traffic area - a heavy platform, and stands arranged at both sides of the road, equipped with a mechanism of vertical displacement of a rope arranged between them with its middle part and fixed in stands by means of brittle fixators. Rope ends going out from fixators are attached to the platform. A jacket from strong elastic air and water impermeable film is freely placed onto the middle part of the rope between the stands. The space between the rope and the inner surface of the jacket is filled with "sticky glue" based on thermoplastic polymers.

EFFECT: as jacket is ruptured, and its cavity unseals, glue provides for power interaction of the rope with vehicle surface, preventing quick release from the rope and thus immediate trespassing of the closed territory.
