<p>The sun awning has supporting members mounted on a building wall and a roller for the cloth contained in a protective housing. Coupled to the members via vertical hinge axes are the ends of two folding arms and which open and shut the awning. A beam for the cloth is coupled to the other ends of the arms on axes parallel to the first axes in the extended position. The arms (10, 11) are adjustable on axes parallel to that of the roller by a bolt (17) at right angles to them and screwing into a tapped bore in a coupling pin (16) turning in the supporting member (2). The other bolt end slides in a bore in a guide block turning in a block coupled to an arm end. A stop (21) on the bolt end furthest from the pin limits movement of the coupling block away from the pin.</p> |
