Precessional apparatus and method thereof
First Claim
1. An apparatus comprising:
- a housing having a precession axis;
a rotor assembly comprising a rotor and an axle, the axle having a longitudinal axis defining a spin axis for the rotor; and
first and second handles, each handle being movably coupled to the housing;
wherein the rotor is rotatable relative to the housing about the spin axis and the rotor assembly is rotatable relative to the housing about the precession axis.

Abstract
A precessional gyroscopic exercise device includes a housing containing a tiltable rotor assembly. The housing and the rotor assembly may be coupled together by a tilt assembly that defines a fixed precession axis for the rotor assembly and allows the rotor assembly to be tilted relative to the fixed precession axis. When the rotor is spinning, and the rotor assembly is tilted contact between the spinning axle and the interior surfaces of a circumferential channel in the housing causes the rotor assembly to rotate about the fixed precession axis, producing a gyroscopic precessional torque—this torque, and resultant wobbling of the device, is opposed by the user for the exercise effect. The tilting mechanism may be associated with handles on the outside of the device, allowing the user to selectively control the tilting of the rotor assembly. The handles may be rotatably coupled to the device, permitting operation of the device using a pedaling motion. The handles are preferably located on the device on or near the precession axis. An alternate embodiment of the device has no tilting assembly or channel, and the spin and/or precession of the rotor assembly is motor-driven.
