Abstract

The present invention provides a method and portable apparatus for massaging particular portions of the body. In one embodiment, the invention comprises a face mask made out of a pliable member and having a plurality of compressible fingers mounted on the inner surface of the face mask for contacting and massaging the face portion. The vibrations are generated by a plurality of coaxially arranged, separately energized motors having weights slidably mounted for radial movement to the shafts of the motors. The motors can be energized through a pulse generating network which supplies power having an oscillating amplitude which produces a corresponding oscillation of the speed of the motors. By setting the speeds of the motors so as to produce beats, a complex vibrational wave is generated in which the vibrational beat frequency is modulated by or modulates the oscillating amplitude of the speed of the motors.

Claims

1. A portable device conforming to a body portion of an animal for massaging the body portion, said device comprising:

a means for generating a plurality of vibrations which includes

a housing, and

a plurality of variable speed motors mounted on said housing;

a pliable member with an external surface and an internal surface having a shape conforming to the part of the body to be massaged, said housing being mounted to said pliable member along one edge thereof; and

a plurality of flexible and resiliently compressible finger-like members mounted at one end thereof to said internal surface of said pliable member, the other end of said finger-like members for engaging the surface of the body portion to be massaged.

2. A portable massaging device as claimed in claim 1 wherein each said motor has

a shaft rotatable by the motor,

a weight mounted on the shaft for perpendicular movement in radial direction with respect to said shaft upon the rotation thereof, and

spring means mounted to said shaft for resiliently opposing the outward radial movement of said weight.

3. A portable massaging device as claimed in claim 1 and further including

means for supplying pulsating electrical power to said motors, said means comprising

means for receiving a non-pulsating electrical power,

means for distributing said power to said motors which include a means for regulating the speed of each motor, and

means for converting said electrical power into pulsating electrical power.

4. A portable massaging device as claimed in claim 1 wherein said finger-like member has a hollow interior cavity and is comprised of a diaphragm section for providing compressibility thereto, and wherein said pliable member has a plurality of apertures therethrough, said apertures being in communication with corresponding cavities of said finger-like members, thereby permitting air external to said pliable member to communicate with said cavity during the compression and expansion of said finger-like members.

5. A portable massaging device as claimed in claim 1 for massaging the face of a human user wherein said pliable member comprises a face-mask having openings therein for the eyes, nose and mouth of the user and a lower section extending below the mouth and chin of the user for engaging the neck of the user, said housing being mounted on the bottom edge of said lower section, and further including releasibly adjustable restraining means for securing said face mask on the face of the user.

6. A portable massaging device as claimed in claim 1 for massaging the scalp of a human user wherein said pliable member comprises a cap section adapted to be fitted onto the head of the user and to substantially cover the scalp area when so fitted, and a lower section integral with said cap section and adapted to substantially cover the neck area of the user, said housing being mounted on the bottom edge of said lower section.

7. A method for massaging a body portion of an animal comprising the steps of:

attaching over the portion to be massaged a pliable covering having a shape generally conforming to the portion to be massaged and comprising a plurality of flexible and resiliently compressible fingers for engaging, at one end thereof, the surface of the portion to be massaged and mounted at the other end thereof to the internal surface of said pliable covering, and a vibration generating means mounted to the lower edge of said attached pliable covering and including a plurality of variable speed motors in coaxial alignment, each motor having a shaft and a radially movable weight rotated thereby;

energizing said motors with a pulsating power supply such that the speed of said motors repeatedly increases and decreases; and

adjusting the speed of said motors such that each said motor operates at a different speed from the other said motor and said motors generate a train of beats.
