ABSTRACT:
A massage device has a rocking member, a synchronous electric motor drive, an elastomeric pivot, a drive connecting member, a rigid structure supporting said pivot and massage elements on the rocking member which move in opposite direction during the rocking motion. Gripping means are secured to the rigid structure, at a location of minimum motion of the rigid structure to minimize the vibration transmitted to the operator; preferably the gripping means are resiliently secured to the rigid structure. The device is weighted so that the moment of force about the elastomeric pivot is sufficient to cause slowing of the motor when the massage members act on the body and increased pressure on the gripping means lowers the frequency of the massage elements. A weight, adjustable in position with respect to the elastomeric pivot, is located on the rigid structure in opposed relation to the drive connecting member; movement of the weight causes change in the amplitude of the massage elements.
