ABSTRACT:
In the case of the parasol or sunshade the bearing forces for holding the awning (1) are transferred laterally by means of an awning bar (3') constructed as a supporting arm, so that the said forces are transferred by means of its associated spreader bar (4') laterally to the central shaft of its spreading open device (5) and from the latter to the other awning bars (4). For this purpose, adjacent to the edge of the awning (1), the awning bar (3') is pivotably retained on a joint (10), which is provided on a holding device (9) displaceable on the parasol post or pole (6). The awning (1) is opened with the aid of a rope (12), which passes from a fixing point (13) below the holding device (9) to a spreading open device (5) located on the parasol top (2). By an upward sliding of the holding device (9) and simultaneous swinging out of the awning bar (3') away from the post (6), a tensile stress occurs on the rope (12) and as a result the awning (1) is opened. The inclination of the awning (1) can be simply and reliably adjusted by modifying the inclination of the supporting arm (7).
