Abstract

A fitness ball has first and second hemispheres, which are connectable to form a complete sphere. The first hemisphere supports a motor having a pair of rotatable eccentric masses at opposite ends of a common drive shaft. The second hemisphere supports a rechargeable battery pack, electronic circuitry and indicators LEDs. The electronic circuit controls the charging of the battery pack and also selectively provides electrical power from the battery pack to the motor to control the rotational speed of the motor to rotate the eccentric masses. The rotating eccentric masses cause vibrations that are communicated from the motor to the two hemispheres. The vibration frequency is controlled by the rotational speed of the motor. The hemispheres have outer covers having a configuration that is easy to grip such that the vibrations are communicated to a users hands. The ball is substantially balanced about an equatorial plane.

First claim

What is claimed is:

1. A portable vibration generation apparatus comprising:

a motor positioned on the motor support structure of the first hemispherical shell and secured to the motor support structure to inhibit movement of the motor with respect to the motor support structure, the motor intersecting the equatorial plane, the motor having a shaft having a first end and a second end, the shaft parallel with and offset from the equatorial plane such that the shaft is located entirely within the first hemispherical shell;
a first eccentric mass secured to the first end of the shaft, and a second eccentric mass secured to the second end of the shaft;
a battery assembly secured to the battery support structure of the second hemispherical shell;
a circuit board assembly secured to the circuit board support structure of the second hemispherical shell, the circuit board assembly electrically connected to the battery assembly to receive electrical energy from the battery assembly, the circuit board assembly generating a motor drive signal; and
at least a first electrical connector and at least a second electrical connector, the first and second electrical connectors engageable when the first hemispherical shell is coupled to the second hemispherical shell, the connectors communicating the motor drive signal from the circuit board assembly to the motor.

2.
