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 the plurality of rollers of the roller 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.

19. A combination adjustable height bearing stand and roller platform assembly, the combination bearing stand and platform assembly comprising:
-
two pairs of legs, each pair of legs comprising a shorter leg and a longer leg, each shorter leg comprising a top end and each longer leg comprising a top end, the top end of each shorter leg being connected to the top end of its respective longer leg by a U-shaped junction plate comprising two opposing distal ends, each U-shaped junction plate wrapping around the top end of one of the shorter legs with the top end of the longer leg of the pair of legs being disposed between the distal ends of the U-shaped junction plate, the distal ends of the U-shaped junction plate and the top end of its respective longer leg being pivotally connected together by a hinge bolt, each pair of legs being pivotally moveable with respect to one another between a parallel position into an angled position, each shorter leg being hollow and the top end of each shorter leg matably receiving a height-adjustable support, each height-adjustable support being secured in place by a fixing element disposed at the joint connection, each height-adjustable support comprising a distal end connected to a fastening element, each fastening element being connected to and supporting an elongated carrier, the elongated carriers being disposed parallel to one another with at least one roller extending between the elongated carriers, each carrier is pivotally connected to its respective fastening element, each carrier being connected to a spindle, the carriers being pivotable between a storage position where the carriers are disposed parallel to the supports and a horizontal position wherein each spindle engages its respective fastening element.

20. A combination adjustable height bearing stand and roller platform assembly, the combination bearing stand and platform assembly comprising:
-
two pairs of legs, each pair of legs comprising a shorter leg and a longer leg, each shorter leg comprising a top end and each longer leg comprising a top end, the top end of each shorter leg being connected to the top end of its respective longer leg by a U-shaped junction plate comprising two opposing distal ends, each U-shaped junction plate wrapping around the top end of one of the shorter legs with the top end of the longer leg of the pair of legs being disposed between the distal ends of the U-shaped junction plate, the distal ends of the U-shaped junction plate and the top end of its respective longer leg being pivotally connected together by a hinge bolt, each pair of legs being pivotally moveable with respect to one another between a parallel position into an angled position, each shorter leg being hollow and the top end of each shorter leg matably receiving a height-adjustable support, each height-adjustable support being secured in place by a fixing element disposed at the joint connection, each height-adjustable support comprising a distal end connected to a fastening element, each fastening element being connected to and supporting an elongated carrier, the elongated carriers being disposed parallel to one another with at least one roller extending between the elongated carriers, each carrier is pivotally connected to its respective fastening element, each carrier being connected to a spindle, the carriers being pivotable between a storage position where the carriers are disposed parallel to the supports and a horizontal position wherein each spindle engages its respective fastening element, each carrier comprising a slit for accommodating its respective spindle when the carriers are moved to the horizontal position whereby movement of the carriers from the parallel position to the horizontal position being in the same direction as movement of the shorter legs from the parallel position to the angled position, and each roller comprising two opposing axial extensions and each carrier comprising at least one inverted U-shaped bearing slit for accommodating one of the axial extensions of each roller, each inverted U-shaped bearing slit comprising two leg sections having different lengths so that moving the axial extension of one of rollers from one leg to the other leg changes the height of said roller when the carriers are in the horizontal position.
