Support which may be orientated in all angular positions and heights and which may be folded and unfolded rapidly in order to facilitate all transport possibilities. Support of the pantograph type calibrated so as to exert at its extremity a force higher than the maximum load intended to be fixed thereto. The hinge is provided with a self-adjustable brake intended to be opposed to the lifting of the assembly, said arrangement differentiating the disclosed support from all existing supports where it is required to lift and block the object to be supported. |
