ABSTRACT:
A height-adjustable nursing bed is provided that includes a pedestal in which the upper frame and the lower frame are connected to one another by a total of four toggle lever pairs. The toggle lever pairs on each side of the bed are additionally connected to one another by horizontally and diagonally extending coupling braces. The horizontal coupling brace connects the toggle levers in the region of the toggle link while the diagonal coupling brace connects a lower toggle lever arm to an upper toggle lever arm. The motor for raising and lowering the upper frame relative to the lower frame extends directly between these two frames such that the toggle levers and their coupling braces act as a parallel linkage of sorts.
