Abstract
Abstract An improved drive system for a massage table that includes a cabinet housing having an open top area, massage means that are formed to the housing and a lounge top having an upper side to support a patient and a lower side. The drive system comprises a motor within the housing, gear reduction means connected to the motor, and a continuous chain moved by the gear reduction means such that the path of the chain forms a plane. An upwardly extending ear link in the chain acts as a driver for the lounge top and a transverse bracket slot on the lower side of the top is capable of receiving the ear link. Removable parallel drill rods extend longitudinally across and are spaced from the lower side of the lounge top. Security brackets extend from the open top area of the housing with each bracket having an opening to accept a drill rod therethrough. Casters extend from the open top area and are aligned in a plane parallel to the path of the chain to allow the table top to slide reciprocally longitudinally.
