The invention originates with a mast (4) on the upper end of which a lock ing and tiltable jib support (8) is arranged. A jib (6) is guided in the jib support (8) such that said jib can be slid and fastened and carries a roof construction (10) on the outer end thereof, wherein said roof construction ( 10) can be extended like a canopy, fan, or frame. To make the extension and retraction of the jib (6) easier, it is proposed that the jib support (8) be designed with at least four guide and locking rollers (18), of which at lea st two engage in a left-handed track and two in a right-handed track (20) of the jib (6). |
