Free-arm canopy, particularly for sun and rain protection

Abstract

A free arm standing parasol comprises a mast, on which an arm with its end of the arm facing towards mast is guided extendably and retractably via a mast slide and is thereby held by a supporting element between the arm and mast while the end of the arm facing away from the mast carries a parasol part with a crown, the parasol part comprising main struts which are radially hinged to the crown and associated supporting struts which are hinged to a corresponding main strut and a parasol slider. The parasol part is connected, via actuating organs, to a drive unit at the mast, a first actuating organ being connected to the mast slide via first deflection rollers for moving the mast slide up and down across a first functional distance, and a second actuating organ being coupled to the actuating organ via an action coupling and being connected to the parasol slider via second deflection rollers for moving the parasol slider across a second functional distance. To improve operability and stability, it is proposed that the second actuating organ be provided with a transmission unit configured in such manner that the first functional distance and the second functional distance have different lengths.
