SUMMARY OF THE INVENTION

This invention relates to a ball on which a person may master a feat usually undertaken by professional circus performers, that is, to balance and move freely in any direction on top of a large ball by taking steps in the opposite direction fromwhich the ball is rolling to gain acceleration or by stepping in the same direction in which the ball is rolling to slow or to stop the movement of the ball. Balancing atop the rolling ball may be accomplished by practice and in complete safety with theaid of the training device, consisting of a ring which holds the ball. Said ring is supported by four legs or standards. There is a caster journaled to the lower end of each standard to support the attachment from the ground. Also, there are twoupright handles attached to the ring. Tops of the two handles are at a height and distance from each other that enable the rider to grasp them with arms outstretched in a natural balancing position.

This invention enables a person to enjoy a new diversion on a vehicle which is novel in appearance and in performance. Skill in manipulating the device as disclosed herein includes balancing on the ball while stepping and turning with agility inany horizontal direction. The rider's balance is aided by the completely symmetrical design and perfect balance of the vehicle itself. In addition to training the user to balance on a ball, the invention can be used for purposes of fun, sport, a meansof developing poise, rhythm, muscular coordination and strength and a pleasant way to reduce and exercise in a relatively small space...plus the satisfaction of accomplishing a new skill. Other objects are that the invention consists of a minimum ofsimple parts, making it convient to assemble, pack and ship -- and its strength and light weight add to its safety and its ease in operation and maintenance.

DETAILED DESCRIPTION OF THE VIEWS OF THE DRAWINGS

Referring now to the drawings in detail wherein like reference numbers depict like parts throughout the several figures. The invention includes a strong, rigid, light-weight composition ball 10, large enough to make the mastery of balancing onthe ball a challenge. Also, size of ball 10 enables rider to jump off without danger of coming in contact with supporting ring 11 or with standards 13. The ring 11 may be a curved collar-like shape or tubular in construction. On the inner side of ring11 there are bearings 12 placed at intervals and at an angle to permit ball 10 to roll freely.

Features of preferred embodiments of the invention may be seen in each of the drawings, but they will be described mainly with reference to FIGS. 1, 5 and 9 which show the first embodiment.

Bearings 12 are made of a non-frictional material to further assure their efficiency. Ring 11 is supported from the ground by downwardly diverging legs or standards 13 firmly attached to ring 11. A swivel caster 14 is journaled to the lower endof each of the standards 13 for support and to keep the entire unit moving in the direction which the user wishes the ball 10 to roll. The frame also consists of upstanding posts 15 which are firmly attached to ring 11. Extension posts 16,telescopically mounted into posts 15 terminate at the top into handles 17. The telescopic mounting permits extension post 16 to be adjusted so as to vary the height of handle 17 above the ground. As particularly illustrated in FIG. 5, sleeves 18connect posts 15 and 16, using adjustable fasteners such as the nuts and bolts shown. Where posts 15 and 16 are connected and reinforced by sleeve 18, there is a bend or flair which results in handles 17 being farther apart when handles 17 are extendedin height, thereby conforming to the rider's arm height and arm span to assist in the rider's balance.

FIG. 2 shows an embodiment employing a tubular ring 21 and wheel castors 24. In the embodiment of FIG. 4, posts 25 are connected to standards 23 instead of to ring 31 which is to hold ball 10. FIG. 4 additionally illustrates one way bearings 12can be mounted on the tubular ring 31. In FIG. 6, part of standards 33 are formed as continuations of posts 35. FIG. 7 shows a tubular ring 41 holding ball 10. The embodiment of FIG. 8 illustrates that extension posts 46 can be made to flare outwardfrom ball 10 at lower portions 38 of posts 45. Additionally, in FIG. 8, handles 47 are curved outward from extension posts 46.

Having thus described preferred embodiments of the invention, it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the scope of the appended claims.
