<p>The protective roof especially for terraces, consists of sheets which overlap each other. At least one sheet is pivot mounted at the end on supports (11) and can be moved by at least one lever (13) which is hinged to a push rod (12). All the sheets (11) can be adjusted in height by means of the lever (13) and push rod (12). The sheets (11) are positioned on two supports (11) running crosswise to the lengthwise direction of the sheets, at the ends. The sheets are adjustable in height by means of a pivot axle (14) fixed on the supports (10). The two supports (10) are made of hollow or half-hollow sections with a push rod (12) in them. At one end of the two push rods (12) is a motorised or manual operating devide (16), which is pivot mounted on a pivot axle (17).</p> |
