ABSTRACT:
A massaging machine promotes circulation in the lower extremities of the body of a user. It comprises massaging components formed as a pair of hollow semi-cylindrical concave dishes, which are driven by an electric motor in pivotal and oscillatory motion relative to a fixed base frame. A mounting plate is displaceable relative to the base frame and can be set in horizontal oscillations by way of a motor-driven single cam and return spring component moving along the longitudinal axis of the massaging components. An arcuate array of cylindrical bearings support each massage component, which in turn is rigidly attached to a lever arm protruding downwards. The lever arms are set in motion to carry out oscillations by way of a motor-driven double cam via rods and return springs. By way of this mechanical arrangement the massaging operation in two directions at once is achieved as in the case of manual massage. Specifically, the massaging is effected perpendicular to the axis of the legs in a radial and oscillating motion and longitudinal to the axis of the legs in a forward and backward motion.
