DOUBLE ROLL-TYPE CLOSURE
A roll type closure has a fixed mounting frame, an inner curtain secured to an inner roller, an outer curtain secured to an external roller rotatably mounted to the inner roller, actuating mechanisms, a bottom rail disposed at the free end of the inner curtain and coupled with the outer roller so as to make the inner and outer rollers integral in rotation, a lever with a hook mounted on the outer roller to move from a retracted position, where the hook does not protrude from the outer roller, to an extracted position, where the hook protrudes from the outer roller, the lever being in the extracted position when the outer curtain is unrolled completely, and a stop member mounted in the frame such that when the lever is in the extracted position the hook is stopped against the stop member, blocking the rotation of the outer roller.
