Patent ID: 7128722

Claim:
A percussive massager comprising: a housing; a motor supported by the housing, having a rotatably driven output shaft; a percussion arm movably connected to the housing and operably driven by the motor output shaft; at least one positioning member; at least two spaced apart massage nodes operably connected to the percussion arm, at least one of the at least two massage nodes being attached to the at least one positioning member, the at least two massage nodes forming a massage surface, wherein at least one of the at least two massage nodes is moved toward and away from the housing by operable connection to the motor output shaft to provide a percussive massage effect; a rotary mechanism rotatable with respect to the percussion arm and engaged with the at least one positioning member such that rotation of the rotary mechanism drives a portion of the at least one positioning member toward and away from a central region of the housing; and an ancillary transmission having an output and an input, the transmission output being connected to the rotary mechanism, and the transmission input being operably engaged with the motor output shaft; wherein the ancillary transmission couples the motor output shaft to the rotary mechanism such that the rotary mechanism drives the portion of the at least one positioning member to progressively increase and decrease the spacing between the at least two massage nodes.
