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