Abstract: A convertible roof element includes a peripheral structure with an opening to be at least partially closed by a membrane, an edge rope and at least one guide rope forming a rope band tensioned against each other. The convertible roof element has a parking position and at least one shading position, the parking position running along the peripheral structure and the at least one shading position running across the opening of the peripheral structure. The edge rope is fixed at its ends via a first tensioning device to the peripheral structure. The at least one guide rope is secured to the edge rope at one end and at the other end to the peripheral structure by means of a further tensioning device. The tensile force of the further tensioning device is variable so that the edge rope is moveable from the parking position into the at least one shading position.

Abstract: A large sunshade for stationary installation in squares, courtyards, etc. has, above the sunshade membrane a sunshade linkage with arms, which can be opened and closed by means of spreading arms. On the arms are provided cover flaps, which are upright in the open state and in the closed state flap in wing-like manner to the side and therefore form a closed, fixed sunshade envelope in conjunction with adjacent flaps.In the central area there are receptacles for the ends of the longer sunshade arms and between which are defined functional areas containing lighting systems, air conditioning openings, etc. By means of a control method with sensors and by means of a control device, the motor opening and closing of the sunshade is controlled in such a way that in permanent operation the microclimate under the sunshade and in particular a group of sunshades is considerably influenced.
