Abstract
A free-engaging drive unit is provided for adjustable beds and the like of the type having a mattress support frame or bedspring supported by two detachable end panels. A crank is mounted on one of the end panels, preferably at the foot of the bed, and is positioned at a conveniently accessible height and location. The adjustable bed has at least one controller shaft, which is rotated to adjust an associated portion of the bed. The free-engaging drive unit includes a drive coupling mounted on the foot end panel and a mating driven coupling mounted on an adjacent portion of the bedspring. When the foot end panel is connected with the bedspring, the drive and driven couplings automatically mesh to operatively connect the crank with the controller shaft, and thereby effect bed adjustment.
