III. There is disclosed massage mechanisms comprising one or more drivers having an angled socket on the end of each driver. The socket has a massage head rotatably engaged therewith by means of a post fixed essentially perpendicularly to the back of the massage head. The massage heads are generally conical in shape and can have collars around the periphery and downward from the base. The socket is angled to a degree which results in the axis of the head and the axis of the driver guide shaft intersecting at a point on the massage head or the driver. The diameter of the post on the massage head is less than the inside diameter of the socket. In operation the edges of the massage head rise and fall about 26.degree. - 30.degree. in an undulating motion without imparting rotational motion while imparting a kneading, massaging action. The driver rotates at about 60-70 RPM which enables the massaging action to be synchronized to the heartbeat. |
