ABSTRACT:
A roll shutter for roof windows, particularly of the hinged casement-type construction, including a roll shutter draw mechanism having two cords, one end of each of which is attached to the lower end of the roll shutter plating. The ends of the two cords are connected to a common cord which after being guided over stationary diverting elements is guided to a drivable spool. In addition, the roll shutter draw mechanism includes a length compensating device having a diverting element which can slide against the force of an elastic member and over which the two cords are guided in tandem. The length compensating device has at least one additional diverting element which can slide together with the slidable diverting element, and the cords are guided in their path from one slidable diverting element to the next by passing over a stationary diverting element.
