DUMBELL CASTOR EXERCISE DEVICE

This application claims priority to U.S. Provisional Patent Application No. 61/488,740 filed on May 21, 2011.

This invention relates to exercise equipment.

In the fitness equipment industry there are many different types of push up exercise devices that seek to improve the overall effectiveness of a push-up exercise. There are also devices that seek to improve on abdominal exercises. Some of the push-up exercise devices move from side to side or rotate about a vertical axis in order to increase the resistance of a push up exercise. There are also abdominal exercise devices that roll to improve the effectiveness and increase the resistance of abdominal exercises. However, there is a current need for a push up exercise device and an abdominal exercise device that allows for movement in all directions and while providing rotation thereby improving the effectiveness of a push-up exercise and an abdominal exercise in one device.

A dumbbell caster assembly comprises a first omnidirectional wheel assembly mechanically coupled to a grip. A second omnidirectional wheel assembly is mechanically coupled to the grip.

Embodiments of the present invention overcome many of the obstacles associated with a push-up device that can also function as abdominal device, and now will be described more fully hereinafter with reference to the accompanying drawings that show some, but not all embodiments of the claimed inventions. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.

FIG. 1 shows the invention in use. User 14 desires to do push-up exercises using hands 20, which will strengthen the user's chest, the user's abdomen or both. User 14 accomplishes this with dumbbell castor assembly 10. Dumbbell castor assembly 10 comprises a first omnidirectional wheel assembly 12, a second omnidirectional wheel assembly 12, a third omnidirectional wheel assembly 12 and a fourth omnidirectional wheel assembly 12 which further comprises omnidirectional wheel sub-wheel 16. The first omnidirectional wheel assembly 12, the second omnidirectional wheel assembly 12, the third omnidirectional wheel assembly 12 and the fourth omnidirectional wheel assembly 12 are mechanically coupled to grip 18 as shown in FIG. 3.

FIG. 2 shows dumbbell castor assembly 10 in more detail. Omnidirectional wheel assembly 12 comprises omnidirectional wheel sub-wheel 16 and omnidirectional wheel drum 24. The first omnidirectional wheel assembly 12, the second omnidirectional wheel assembly 12, the third omnidirectional wheel assembly 12 and the fourth omnidirectional wheel assembly 12 are mechanically coupled to grip 18 with fastener 22 as shown in FIG. 3. Similarly, the first omnidirectional wheel assembly 12 comprises a first omnidirectional wheel sub-wheel 16, the second omnidirectional wheel assembly 12 comprises a second omnidirectional wheel sub-wheel 16, the third omnidirectional wheel assembly 12 comprises a third omnidirectional wheel sub-wheel 16 and the fourth omnidirectional wheel assembly 12 comprises a fourth omnidirectional wheel sub-wheel 16.

FIG. 3 shows index loaded assembly drawing of dumbbell castor assembly 10. Omnidirectional wheel assembly 12 is mechanically coupled to grip 18 by fastener 22. As noted in FIG. 4, this construction technique allows for omnidirectional movement of dumbbell castor assembly 10. While four omnidirectional wheel assemblies 12 are shown in the figure in the construction can be done with any number of omnidirectional wheel assembly 12 combinations. These components can be made from a large number of materials including steel, aluminum, stainless steel, wood, plastic or any other material.

FIG. 4 displays the omnidirectional nature of omnidirectional wheel assembly 12. Note that omnidirectional wheel drum 24 enables omnidirectional wheel assembly 12 to rotate in the horizontal direction. Similarly, omnidirectional wheel sub-wheel 16 enables omnidirectional wheel assembly 12 to rotate in a vertical direction. These two movements work in conjunction to allow dumbbell castor assembly 10 to be used as an abdominal exercise device or a push-up exercise device.
