Abstract

See full text

A hand-held vibratory massager has a self-contained applicator head which is resiliently connected to a hand grip for limited movement in substantially all directions relative to the hand grip. A drive motor and an eccentric flyweight are mounted together within the applicator head for making it as a self-contained vibrating unit. The eccentric flyweight is connected to a motor output shaft in an eccentric relation thereto for imparting vibration to the applicator head upon rotation of the output shaft. Also mounted within the applicator head is a counterweight which provides dynamic balancing of the applicator head in such a manner as to coincide the center of mass of the entire applicator head with that of the flyweight in the axial direction of the output shaft.
