Wheeled Exercise Device

This invention relates to an exercise device and novel methods of exercising. The invention provides an exercise device which can be economically manufactured, which is of convenient size and weight for shipment and transportation, and which can be used in any convenient location to provide exercise for a substantial number of body muscle groups. The invention also provides novel forms of exercise using the device.

An exercising device in accordance with the invention comprises an axle member, stirrup means or the like associated with the axle member for releasably supporting both of a user's feet on the axle member, and wheel means associated with the axle member for providing rolling support for the axle member and stirrup means on a support surface with ground clearance for the user's feet.

A method of exercising in accordance with the invention comprises assuming a basic push-up position on a support surface, with the feet supported on wheel means above the surface, then performing at least one of the actions comprising (a) walking along the surface on the hands with the wheel means rolling along the surface and (b) maintaining the hands in substantially stationary position on the surface and using the body to roll the wheel means along the surface toward and away from the hands.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout.

FIG. 1 is a perspective view of a person performing an exercise and using an exercise device in accordance with the invention.

FIG. 2 is an elevational view of the exercise device.

FIG. 3 is a sectional view on line 3--3 of FIG. 2.

FIG. 4 is a perspective view of a foot stirrup.

FIG. 5 is an elevational view of a part of a modified form of exercise device in accordance with the invention.

As shown more particularly in FIGS. 2 and 3, an exercising device 10 in accordance with a first embodiment of the invention comprises a rigid axle 12 with a pair of wheels 14 rotatably secured at its opposite ends for rotation about an axis defined by the axle, and a pair of hollow boot-shaped stirrups 16 adjustably mounted on the axle between the wheels. The stirrups may, for example, be molded in plastic or other suitable material, and are each generally L-shaped (as shown in FIG. 4) so each stirrup includes a shin support portion 16a and a foot receiving portion 16b with an open toe 16c. As shown, the stirrup shin support portion 16a has an open top at 16d and the foot receiving portion 16d has a rear wall 16e which engages the sole of a shoe 17 worn by a person 19 using the device with the breast of the heel 17a engaging the upper edge of the rear wall 16e to limit insertion of the shoe 17 into the stirrup 16. The interior surface of the stirrup may be padded for secure engagement with the feet or shoes of the user.

The stirrups 16 are mounted on axle 12 by collars 18 connected to the respective stirrups by pivotal connectors 20 allowing a user to swivel his or her feet when mounted in the stirrups. Also, suitable adjustment means (not shown) such as set screws may be provided for altering the position of the stirrups along axle 12 to suit a particular user. The diameter of wheels 14 are such as to provide ground clearance for a user's feet when slid into the stirrups. The wheels may, for example, be about 12 inches in diameter, axle 12 may be 26 inches long, and the stirrups may be about 20 inches apart.

To perform exercises in accordance with the invention, a user positions his or her feet in the stirrups, and assumes a basic push-up position on any suitable support surface, as shown in FIG. 1. From this position, the user 19 may, for example, perform an exercise comprising walking along the surface on the hands 21, with the feet being rollingly supported by the exercise device. Another exercise comprises maintaining the hands 21 in stationary position, the user would draw their feet uo toward the hands while raising the rump as the feet were drawn under the body until a "front-line" football stance position is achieved and then extending the legs into the starting push-up position thus completing one exercise. Other exercises such as conventional push-ups may be practiced with the arms being in different angular relations to the user's body.

In the modified form of the invention shown in FIG. 5, wheels 14' are journaled in caster yokes 22 which have a vertical pin 24 extending through axle 12'. This arrangement allows the wheels to swivel about a vertical axis and provides the device with a further degree of flexibility. It may also be possible for the device to have only a single wheel between the stirrups instead of wheels at the ends of the axle and only one stirrup may be provided or used to even further strengthen certain muscles. The castering support wheels 14' and the swiveling stirrups 16 enables the exercise device and thus the legs to be moved laterally to increase the types of exercises which can be practiced by using the exercise device.

It will be appreciated that the invention provides a compact and lightweight exercising device which can be used in any convenient location, including confined areas, to provide extremely effective exercise to many parts of the body including the stomach, chest, shoulders, arms and back.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
