Gyroscopic exerciser
First Claim
1. A gyroscopic exercise device comprising:
- a gyroscopic rotor comprising a rotor balanced around a primary axis of rotation, and a secondary axis of precession;
a housing for protecting the gyroscopic rotor from inadvertent physical contact by a user while permitting limited access to the gyroscopic rotor during a manual gyroscopic pull start;
an axle upon which the right rotor portion and the left rotor portion are mounted, wherein the axle is oriented to have a longitudinal spin axis in the horizontal direction, further comprising a pair of opposite ends of the axle;
an annular racetrack for rotatably holding the axle at the opposite ends of the axle which are shaped to rotate in the annular racetrack, wherein the annular racetrack is oriented about the precession axis crossing the longitudinal spin axis, wherein the precession axis is perpendicular to the longitudinal spin axis, and wherein the opposite ends fit into the annular racetrack which is formed as a groove with a circumferential profile disposed around an internal circumferential surface of the housing, allowing both rotation and precession of the gyroscopic rotor and axle;
a pull handle attached to a pull cord in a swivel relationship, wherein the pull handle is for pulling the pull cord, wherein the pull cord is attached to the handle at a pull cord first end;
a grip sleeve made to be retractable, wherein the grip sleeve further comprises a grip sleeve and a spool member fitting around the axle, and attached to the pull cord at a pull cord second end, wherein the spool member receives and stores the pull cord in a coil around the spool;
wherein the grip sleeve further comprises a one-way bearing member mounted to the spool member and the axle, and wherein the one-way bearing member allows rotation of the spool member in one direction around the longitudinal spin axis, but stops rotation of the spool member in the opposite direction, wherein the one-way bearing has a bearing housing with a bearing housing exterior surface which is mounted to the spool member;
wherein the grip sleeve further comprises a spring which is coiled around the axle and has a first inside end attached to either the grip sleeve housing or the spool, and a second outside end attached to either the grip sleeve housing or the spool, wherein the spring is extended when a user pulls the cord away from the spool, and wherein the spring retracts when the user releases the cord, whereby the spring biases the spool to rewind the cord after the cord is pulled and released, whereby pulling the pull cord provides a positive engagement to initiate a high speed precession of the gyroscopic movement unit.

Abstract
A gyroscopic exercise device has a pair of handles attached to a housing. A user holds and rotates the handles along cone-like paths causing precession of a rotor, which is rotating about its spin axis, to provide resistance to the user. The device has an axle disc that holds ends of an axle of the rotor. The periphery of the axle disc and the ends of the rotor axle are within a circular race in the housing. A retracting spool allows pull starting. An optional motor attached to the axle disc has a wheel for rotating the rotor about a spin axis by a temporary supply of power from included batteries in one of the handles. An optional abdominal rolling ring provides abdominal exercise.
