Abstract
A combination adjustable height bearing stand and roller platform assembly is provided which can be fixed at a pre-adjusted height. The combination bearing stand and roller assembly includes two pairs of legs with each pair of legs being pivotally connected together at a joint connection so that the legs can be brought from a parallel position used for storage to an angled position. The corresponding legs of the two pairs of legs are connected by cross-connectors. The legs are tubular and one leg of each pair of legs receives a height-adjustable support which can be secured at a pre-selected height by a fixing element. The top ends of the height-adjustable support are connected to fastening elements which, in turn, are pivotally connected to two carriers which support a platform assembly. Both the platform and bearing stand legs are pivotable between a collapsed and parallel storage position to an angled and horizontal position respectively using a single motion.
