Abstract

The invention relates to a folding parasol. The inventive parasol comprises a sunshade surface (1) which is fixed to bars which are in turn connected to a bushing (16) by means of lower arms, said bushing being equipped with a locking button (17). According to the invention, the bushing (16) can slide axially in relation to an upper rod (2) of the parasol, which can be inserted into a lower ground-fixing rod (3) by means of a height-adjustment element (6). The aforementioned bars comprise various different articulated segments (19 to 21, 24 to 27), while the rods (2, 3) comprise various different tongue-and-groove or telescopic segments (4, 5, 7 to 10). In this way, the parasol can be folded such as to occupy very little space.
