Safety edge for automatic gates

摘要

An electromechanically actuated mobile protection device for automatic gates (11), comprising a protective rib (10) firmly fixed to the top of the advancing front face (12) of the gate (11) along its entire length. A steel cable (13) is vertically positioned inside the rib (10) and connected, by a transmission pulley (14), to a fixed trolley (15). The protection rib (10) is profiled in the shape of a triangular prism and made of flexible rubber, so that at the instant the rubber surface meets an obstacle in its forward motion, the steel cable (13) transmits the resulting deformation to a mobile slide (16) controlling an electronic protection and/or safety device, which in turn acts by interrupting the electrical power feed to the gate actuating motor (11), thus breaking off its motion.
