FIRE BARRIER Russian patent published in 2017 - IPC A62C2/00 

FIELD: fire safety.

SUBSTANCE: fire barrier contains a protective sheet made of non-combustible material, which is fixed on the upwardly oriented rods. The bearing rod is made telescopic from three extending sections, with loops lying in one plane oriented along the longitudinal axis of the rod rigidly fixed at the upper ends of the sections on their lower side. The loop of the lower section is made with the possibility of a hinged connection with the spacer. The loop of the middle section is connected to the sliding housings of the lower support by means of a ball hinge, installed on both sides of this loop, equipped with a removable horizontal spacer. The loop of the upper section is hinged to the sliding housing of the upper support, the lower end of the extending section of which is provided with a detachable T-shaped tip which ends are pivotally connected to removable support links, the lower ends of which are pivotally connected to the hinged connections of a removable horizontal spacer with horizontal loops fixed at the lower ends of the lower support housings. The free end of the spacer is hinged to the horizontal spacer. The sliding housings of the lower support and the sliding housing of the upper support are provided with stoppers configured to deactivate their sliding. The bearing rod is provided with a lifting mechanism, which is made in the form of a pulley and a lifting drum. The pulley is rotatable about a horizontal axis at the upper end of the upper extending section. The lifting drum is rotatable about a horizontal axis, is provided with a handle for rotating it and a stopper for rotation and is installed in the lower part of the lower extending section. The lower ends of the lower extending section and the lower ends of the extending sections of the sliding housings of the lower support are provided with foot bearings, which are configured to be fixed in the ground by means of drive anchors. The lower end of the cable passed through the pulley is lowered to the ground and is equipped with a hook, and the second end is wound on the lifting drum. The sheet is made of steel, basalt or carbon fiber in the form of a mesh sheet.

EFFECT: possibility of effective use in forest fire fighting, including crown fire fighting, using for forming a protective fire perimeter of sufficiently large extent, preferably near populated areas, effective even during crown fires.
