Abstract
Method—and device for the implementation thereof intended to provide a protection system for barriers which are movable along an operating path and actuated by a motor, such as roller blinds, gates or the like, comprising the steps of connecting the barrier, with play, to a fixed part () so that the barrier is able to move independently of the action of the motor over a travel section (); defining within the section () a set of safety positions corresponding to a safety position for the barrier; detecting along the travel section () the actual position of the barrier with respect to the fixed part (); preventing or reversing the action of the motor and/or the movement of the barrier when the barrier, inside the travel section (), does not have a position included within the set of safety positions.
