BY a 44N United States Patent Olhce 3,512,798 Patented May 19, 1970 3,512,798 SKATE BOARD DEVICE Samuel Siegel, 1956 N. Vermont Ave., Los Angeles, Calif. 90027 Filed Dec. 4, 1967, Ser. No. 687,699 Int. Cl. B621) /00; B62k l7/00 U.S. Cl. 28d-87.04 5 Claims ABSTRACT 0F THE DISCLOSURE SUMMARY OF THE INVENTION This invention relates to childrens toys, particularly skate boards. The present skate boards can only be ridden in one direction and require a turning radius. In the present invention the child riding the board puts his foot on one side of the board. He will now be riding on one of the small balled casters and the large center ball in a slightly slanted position. At this time he is pushing with his other foot. When speed builds up, he places his other foot on the opposite side of the ball. When balance is obtained, he will be suspended on the large center ball and can cause the board to change direction by shifting his .feet or slightly changing his balance. When the board is not moving, the board may be balanced and various maneuvers may be performed such as spinning the board and body around the ball.

Referring now to the drawings in which:

FIG. 1 is a top elevation of the skate board device;

FIG. 2 is an end elevation of the skate board device;

FIG. 3 is a side elevation ofthe device.

FIG. l shows a wing-shaped board 10, which has a large center hole 12. Mounted in this hole is a large round ball 14. This ball 14, is mounted on an axle 16 which is shown as extending completely through the wingshaped board 10. While it is not necessary to extend this axle 16 entirely through the board 10, in the preferred embodiment it adds strength to the device.

Referring now to FIG. 2, a plurality of wheels 18 are provided. These wheels are elevated from the ground so that when the skate board device is balanced the only surface on which it is riding is that of the large center ball 14.

In the preferred embodiment of the present invention the large ball 14 has a llattened riding surface 20 which stabilizes the ball and makes balance easier.

FIG. 3 shows how the stabilizing balls 18 are adjustably mounted by providing a slotted mounting bracket 22. When the rider becomes proficient he may raise the stabilizing balls and thus be able to make sharper turns without dragging one of these stabilizing balls 18.

These stabilizing balls 18 may also be made from round multi-directional caster devices common in the art.

While the preferred embodiments have been shown and described, the invention is not to be construed as limited to the specific details disclosed herein, except as included in the following claims.

I claim:

1. A skate board device comprising:

a board with a large center hole containing a large center ball rotatably mounted therein and a plurality of smaller stabilizing balls rotatably mounted on said board around said center ball, and

said center ball having a flattened riding surface.

2. The skate board device of claim 1 wherein said board comprises a parallelogram with said smaller stabilizing balls toward the apexes of said parallelogram and equally spaced from said large center ball.

3. Thev skate board device of claim 1 wherein said large center ball is mounted in said larger center hole by an axle running through said ball and said board.

4. The skate board device of claim 1 wherein said smaller stabilizing balls are aixed to said board by a U-shaped bracket wth an axle means running through said bracket and said balls, said axle means being adjustable in said bracket so that said stabilizing balls may be adjusted above the attened riding surface of said large center ball.

5. The skate board device of claim 1 wherein said smaller stabilizing balls are aixed to said board by bracket members and raised above said attened riding surface of said large center ball.
