Abstract: A massaging device driven by a water wheel and having a plurality of fingers spread in concentric rings about an arched cover. The fingers are supported in and actuated by a rotating camming platform including a series of concentric camming surfaces with curved bases and irregularly shaped annular sidewalls. The fingers are reciprocated along their vertical axes to create a wave-like motion relative to the cover. Concurrently, the fingers are actuated to pivot about a central transverse axis defined by pin members located on opposite sides of the fingers. When driven by a water wheel, the device contains a water channel along its base, which channel extends to a water chamber containing the water wheel. The wheel is turned by water flow through the chamber thereby rotating the camming platform to which it is coupled by way of gears.

Abstract: A driving device of the massaging chair including a main shaft, a bevel gear mounted on one end of the main shaft, a worm rod mounted on another end of the main shaft, and a driving rotor mounted slidably between the bevel and the worm rod. When the main shaft is driven by a motor to turn forward, the driving rotor is engaged with the bevel gear to actuate a kneading shaft of the massaging chair. When the main shaft is driven by the motor to turn backward, the driving rotor becomes disengaged with the bevel gear and moves away from the bevel gear to engage the worm rod so as to actuate a beating shaft of the massaging chair.

Abstract: A back massage and exercise device comprising a substantially flat, elongate frame able to be utilized on a supporting surface, with the frame having a pair of long sides joined together by a pair of short sides and being several times as long as it is wide. A roller array in the form of a parallel series of elongate rollers are loosely mounted in a spaced apart, operational relationship between the long sides of the frame. The frame has an operative position in which a lower portion of substantially all of the rollers is in contact with the supporting surface, with an upper portion of the rollers being available for directly supporting the body of a user. The user is able to readily bring about back and forth rolling movement of the frame along the supporting surface at such time as he is lying on the rollers, with the motion of the upper portions of the rollers during such movement of the frame bringing about a massaging action to the portion of the user's body in contact with the rollers.

Abstract: A therapeutic treatment machine for alternatingly applying equal amounts of compression and traction to the body of a patient includes a platform having an upper body support pad with selectively controllably resistance to forward and backward displacement, rotatable rollers to support the lower back, buttocks and thighs of the patient, and a selectively controllable motor driven foot support platform displaceable forward and backward predetermined distances and speeds. The distance between the upper body support pad and the foot support platform is adjustable to accommodate differences in patient torso lengths and the magnitude of compressive and tractional force can be selectively controlled by the patient.

Abstract: A massager for incorporation internally of a seat, and the seat, which may be reclinable, either in a seat portion thereof or a backrest or in both the seat portion and backrest for massaging an occupant seated or reclining on the seat. The massager has a pair of rotatable massage rollers extending longitudinally in opposite directions on a common longitudinal axis and are transported on a self-propelled carriage which travels alternately on two rectilinear paths in the form of parallel tracks. The carriage carries a pivot normal to the longitudinal axis of the massage rollers about which the longitudinal axis is selectively rotated by an electric motor so that the massage rollers are rotated in a circular path for massage different body parts of the seat occupant than when travelling on the rectilinear paths.
