Abstract
An electromotive massage apparatus for beating and kneading body comprises clutch means with a movable gear and pulley blocks in association with said clutch means. Said movable gear which is slidable according to revolution of a motor engages with either of pulley blocks and then transmit said revolution to the gear engaged pulley block. This gear engaged pulley changes said revolution into reciprocating motion by means of eccentric members and further transmit the reciprocating motion to a pair of oscillating yokes. Accordingly, said oscillating yokes which are cooperable with the gear engaged pulley block are oscillated pivotally with respect to axes for pivotal movement, so that vibrators beat and knead body as the motor rotates.
Claims3
An electromotive massage device comprising in combination:
- an electrically-driven power means for driving a shaft rotatably;
- first drive shaft means including a first drive shaft adapted to be driven by the electrically-driven power means, and a second drive shaft spaced axially from the first drive shaft, and a third drive shaft mounted as a tubular shaft coaxially around and separately rotatably from the first drive means;
- and a tubular gear means providing a tubular gear slidably shiftable axially to and fro for shifting driving torque alternately between engagement with the second drive shaft and the third drive shaft providing for alternate driving of the second and third drive shafts selectively intermittently as desired;
- lever selector means for selectively moving the tubular gear means in either of to and fro axially engageable directions for alternate driving of the second and third drive shafts;
- a massage means providing for alternate use as a massager and a tapping device, including a pivotably mounted shaft element and a mounting base therefor;
- a first lever means for drivably interconnecting said pivotably mounted element and one of the second drive shaft and the third drive shaft and including a first eccentric cam mounted to impart reciprocatable upright motion to said pivotably mounted element;
- and a second lever means drivably interconnected to the remaining one of the second drive shaft and the third drive shaft and including a second eccentric cam mounted to impart reciprocatable upright motion to the massage means, and a tapping element axially reciprocatably mounted and adapted for horizontal movement on the mounting base and drivably connected to said second lever;
- such that the pivotably mounted element is movable pivotably uprightly intermittently selectively and alternately said tapping element is reciprocatable axially horizontally intermittently selectively.
