A precessional exercising device utilizing a housing containing a spinning mass which forms the rotor of a motor for spinning the mass. The spin axis of the mass is perpendicular to upper and lower flat housing surfaces adapted to be held in the palm of the hand. Alternatively, the housing may be coupled to a remote handle by a linkage permitting rotation of the handle about two mutually orthogonal axes. Also, the housing containing the spinning mass may be coupled to a remote foot plate for similar rotation of the housing by movement of the foot. The housing containing the spinning mass may be affixed to a hinged deck upon which the upper part of the body may be secured for bending and twisting exercises. Exercise of the muscles is achieved by making arcuate exercising movement which rotate the spin axis of the spinning mass within the housing, and by resisting the precession torque generated as a result of rotation of the spin axis of the spinning mass.

A gyroscope is firmly held against the back side of the human hand to reduce or eliminate the effect of naturally occurring tremors such as essential tremor or other tremor. The gyroscope is driven by an electric motor energized by batteries. The batteries are mounted near the periphery of the gyroscope to enhance the gyroscopic action. In a modified form of the invention the motor is not mounted on the back side of the hand but is a separate unit to which the gyroscope can be readily coupled and uncoupled.
A wrist ball comprises a lower shell and an upper shell which is joined with the top of the lower shell. The lower shell is provided therein with a bracing ring and a rotary member. The upper shell is provided at the top thereof with a round opening. The rotary member is provided in the periphery thereof with a groove which is in turn provided with a first engaging portion. The round opening of the upper shell is sealed off by a cap which is provided with two through holes for receiving a pull member. The pull member has a rod portion which is provided with a second engaging portion that is engaged with the first engaging portion of the rotary member. The rotary member is actuated by the pull member to rotate.
A wrist exerciser comprises a lower shell and an upper shell. The lower shell is semispherical and provided therein with a support ring and a rotary member. The upper shell is hollow and semispherical and provided in the top thereof with a round opening. The lower shell is provided with two lower protruded plate members extending therefrom symmetrically and having a first through hole. The upper shell is provided with two upper protruded plate members corresponding to the lower protruded plate members and having a second through hole opposite to the first through hole. The second through hole is provided in the periphery thereof with a plurality of second columnar bodies, each having a hole. The upper protruded plate members and the lower protruded plate members are fastened together by a plurality of screws which are fastened into the holes of the second columnar bodies via the through holes of the first columnar bodies.
A gyroscopic exercise device has a pair of handles attached to a housing. A user holds and rotates the handles along a cone-like path causing precession of a rotor, which is rotating about its spin axis, to provide resistance to the user. The device has a ring guide that holds ends of a shaft, which is coupled to the rotor. The periphery of the ring guide and the ends of the shaft are within a circular race defined by the housing. A motor attached to the ring guide drives a wheel that rotates the rotor about a spin axis by using energy provided by batteries in one of the handles. The energy passes through a conducting conduit that rotates about the precession axis. The ring guide, motor, and rotor can rotate together during precession of the rotor.
The present invention is a combination of three interconnected gyroscopic ring-like rotating masses, with each of the three ring-like masses being configured to rotate in various planes, depending on the desired orientation. Regardless of the orientation of the three rings, each of the three interconnected rotating masses will share substantially the same center of gravity and generate a separate yet interactive kinetic energy and angular momentum in each of the three planes. Additionally, a series of pedestal supports for supporting the three ring-like masses is disclosed.
