FIELD: road building, particularly devices, which prevent vehicle access into urban areas, pavements, parks, public gardens and so on. ^ SUBSTANCE: barrier comprises support panel with orifice and post installed in the support panel and provided with upper lid and lock pinned to the post. Lid pin is kinematically connected with locking mechanism made as engaging means, which may rotate about axis and provided with extension cooperating with lower surface of support panel in working position. The axis is off-centered and kinematically connected with engaging means through connecting rod. Upper head of connecting rod is put on the axis, lower head thereof is attached to engaging means. Part of engaging means surface is radial and radius center is offset with respect to engaging means axis so that radial surface cooperates with upper surface of support panel in working position. Extension cooperating with lower surface of support panel is formed as a cut made in engaging means. ^ EFFECT: increased ability and rate of barrier disassembling. ^ 15 cl, 5 dwg |
