The foldable cantilever comprises a supporting arm formed by a U-profile. A supporting flap extends obliquely from the web of this profile section. The supporting arm is hingedly connected to a jib. A strut is, furthermore, also hingedly connected to the jib. The supporting arm, the jib and the strut are U-shaped profile sections. In use the U-profile which forms the strut supports itself on a supporting flap formed on the web of the profile section forming the supporting arm. A strut controlled slider is arranged in the supporting arm. The strut is connected by a tension spring to the jib. This tension spring leads to the lower edge of the strut being biased against or towards, respectively, the supporting arm. Accordingly, the foldable cantilever occupys in its shipping state only a small space and it is possible to open it to its operating position by means of only one manually made movement thereof. |
