Abstract: The present invention relates to means and methods for tensioning duck or canvas. In particular, the present invention provides a tensioning system wherein a canvas can be tensioned dynamically along one or two sides of a frame. The present invention also further provides a method for dynamic tensioning of a canvas on one or two sides of a frame.

Abstract: A slatted roof for a terrace canopy. The slatted roof is provided with a set of parallel slats (7, 7?), wherein two adjacent slats have a different bending resistance. The more rigid slat (7?) is intended for carrying, e.g. attaching thereto or integrating therein. of one or more desired components. These components then exert an additional load onto the more rigid slat such that both slats have substantially the same deflection. In this way, functional elements can be attached to a slat of the slatted roof without obtaining a slat with deviating deflection.

Abstract: Heating louvre (11) for a louvred roof comprising at least two girders which extend parallel to each other and to which several louvres are rotatably connected between an open position and a closed position. The heating louvre (11) is provided with an underside (13). A slot is provided in the underside (13) for fitting a heating element (12) inside the heating louvre (11). After the heating element (11) has been fitted, the cavity (15) is at least partially sealed by it and the heating element (11) is provided to heat a position between the louvred roof and the ground surface by means of radiant heat. By using a slot in combination with a heating element (12) based on radiant heat, it is possible to heat the position between the louvred roof and the ground surface, as the heating element (12) is not fully surrounded by the heating louvre (11).

Abstract: A roof arrangement comprising a panel arrangement attached to a frame is disclosed. The panel arrangement includes N panels slidable between a distributed position and a stacked position; and (N?1) pairs of reinforcing ribs each comprising an upper and a lower reinforcing rib. The sum of heights of the upper and lower reinforcing ribs of each pair of reinforcing ribs is the same. Each two adjacent panels extend in a different horizontal plane. Bottom sides of all lower reinforcing ribs and top sides of all upper reinforcing ribs are in a horizontal plane. By providing the frames of adjacent panels in different planes, the mutual positioning of the reinforcing ribs and the variation in length of the upper and lower reinforcing ribs in adjacent panels, it is possible to partially (or completely) slide these adjacent panels over each other without thereby increasing the height. Hence, this limits the stack height.
