SPIRAL UNIT FOR MOVABLE BARRIER AND VEHICLE TO DELIVER AND DEPLOY THEREOF Russian patent published in 2005 - IPC

FIELD: building or like structures, particularly wire barriers adapted to isolate terrains for military and other purposes.

SUBSTANCE: spiral unit comprises three spirals produced of barbed band oriented one to another to define triangular prism. Neighboring coils of each spiral are connected in pairs in points equally spaced along coil circumferences and located on single straight line in spiral length direction. Spirals have equal diameters. Rear and front spiral ends are fixedly secured to rear and front frames correspondingly. All coils of neighboring spirals are connected in pairs one to another in contact points. Connection points of neighboring spirals and connection points of the nearest spiral points of each separate spiral are spaced equal distances one from another. Vehicle for barrier delivering and deployment comprises panel with console secured thereto and passing through the upper spiral. Console extends in horizontal direction and also passes through rear and front spiral unit frames. Catcher for rear frame supporting is formed on the panel. In transport position upper end of rear frame is connected to console through locking pin.

EFFECT: increased rigidity of spiral unit, improved barrier properties thereof, reduced number of standard sizes, simplified spiral production and increased speed of movable barrier deployment.
