Abstract:
1. A portable massage apparatus for use by an operator in the therapeutic application of repetitive vibratory force to a recipient, the massage apparatus comprising: a housing having a longitudinal axis, the housing defining a hand portion extending radially outwardly from the longitudinal axis sized to fit and accept simultaneously both the palm and fingers for the hand of a user, and a cuff portion, and an electrically nonconductive bracket connecting and separating the hand portion and cuff portion, the bracket being configured to insulate and isolate the hand portion and the cuff portion from the operator and the recipient respectively, the hand portion being sized and shaped for suitable use by a human user such that the hands of the user always are generally perpendicular to the longitudinal axis and axially outboard of the bracket in application use, the axis always passes through the hand or hands of the user during use, the hand portion further having a top for the accepting the user's hands, a bottom, and a side defining first enclosed chamber, the cuff portion having an outer surface and an inner surface defining a second chamber; a motor mounted within the first enclosed chamber, the motor having a rotatable drive shaft extending along the direction of the longitudinal axis from the first enclosed chamber into the second chamber; an oscillating assembly mounted within the second chamber, the oscillating assembly including an offset cam operatively connected to the drive shaft, and a plate mounted about the offset cam axially outwardly thereof, the plate oscillating in an orbital motion upon rotation of the drive shaft thereby translating rotary motion of the drive shaft into orbital oscillations of the plate; and a counterweight mounted within the housing wherein the counterweight decreases vibration in the hand portion by compensating forces generated by the plate as the plate oscillates in the orbital motion.
