Abstract

A hand held, portable, rechargeable electric vibrator which includes a handle portion and a spherical vibrating portion. The handle portion houses a rechargeable battery controlled by an on-off switch. The spherical vibrating portion is substantially hollow and houses an electric motor completely therewithin. The motor includes a shaft having a pair of eccentric weights mounted on respective ends thereof. The spherical vibrating portion is connected to the handle portion by a flat, resilient spring member, and a rubber sheath encloses the spring as well a the electrical wires which connect the battery with the motor. Upon actuation, the eccentrics revolve about the motor so as to impart a vibratory motion to the spherical portion of the device. Embodiments are also disclosed which contain more than one vibrating portion.

Claims

1. A massager, which comprises:

a handle portion;

a vibrating portion;

resilient means interconnecting said handle portion with said vibrating portion; and

electric motor means mounted within said vibrating portion and including a substantially cylindrical housing, an axial shaft concentrically mounted in said motor housing and having one end portion extending beyond one end wall of said housing, and eccentric weight means mounted to said one end portion of said shaft;

said eccentric weight means including a first weight which comprises a substantially flat, triangular shaped base positioned adjacent said end wall of said housing and whose apex is connected to said one end portion of said shaft, and a body portion disposed adjacent the cylindrical outer surface of said motor housing and which extends integrally and transversely from said base so as to rotate therewith about said motor.

2. The massager as set forth in claim 1, wherein said vibrating portion comprises a substantially hollow housing having means for mounting said electric motor therein.

3. The massager as set forth in claim 2 wherein said hollow housing is substantially spherical and includes a ring-shaped annulus centrally positioned therein within which said electric motor is mounted.

4. The massager as set forth in claim 3 wherein said handle portion is elongated and includes means for selectively supplying electrical power to said electrical motor.

5. The massager as set forth in claim 4, wherein said electrical power supplying means comprises a rechargeable battery positioned within said handle portion and including a connector means for selectively receiving battery recharging apparatus.

6. The massager as set forth in claim 1, wherein said shaft includes a second end portion which extends beyond the other end wall of said cylindrical housing.

7. The massager as set forth in claim 6, further comprising a second weight substantially identical to said first weight and connected to said second end portion of said shaft.

12. The massager as set forth in claim 1, wherein said body portion of said weight includes an arcuate inner surface spaced adjacent and concentrically with respect to said cylindrical outer surface of said motor housing.

8. A massager, which comprises:

an elongated handle portion having electrical power supply means therein;

a vibrating portion including a substantially hollow spherical housing;

resilient means interconnecting said handle portion with said vibrating portion; and

electric motor means mounted within said housing and including a shaft and weight means eccentrically mounted on said shaft, said motor means connected to receive electrical power from said power supply means to rotate said shaft;

wherein said resilient means comprises a substantially flat elongated spring, the plane of which is positioned parallel to the axis of said motor shaft.

9. The massager as set forth in claim 8, further comprising a rubber or like sheath which encases said flat spring.

10. A massager, which comprises:

a handle portion;

a vibrating portion;

resilient means interconnecting said handle portion with said vibrating portion;

electric motor means mounted within said vibrating portion; and

a second vibrating portion containing a second electric motor means and connected to said handle portion via second resilient means.

11. A massager, which comprises:

a handle portion;

a vibrating portion;

resilient means interconnecting said handle portion with said vibrating portion;

electric motor means mounted within said vibrating portion; and

a plurality of vibrating portions each containing its own electric motor and connected to said handle portion via a plurality of respective resilient means.
