Roof arrangement for a terrace canopy, kit of parts for building the roof arrangement, and terrace canopy comprising the roof arrangement

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.
