17a and 17b projecting from the inner surface 18 ofgyral wheel 10 on one side thereof. Another circular skate track 19 is formed by a pair of

skate bosses

19a and 19b projecting from the inner surface 18 of gyral wheel 10 on the other side thereof.

Circular tracks

17 and 19 are of like construction. A recessed portion 20 is provided between these

tracks

17 and 19. An alignment slot 17' is provided along the outer side ofskate boss 17a of circular truck 17; and an alignment slot 19' is provided nlong the outer side of skate boss 19!) of circular track 19. These alignment slots 17' and 19' accommodate skate guide members as hereinafter described.

provide an open wheel provide entertainment and exercise Adapted to ride on the

circular tracks

17 and 19 formed on the inside surface 18 of wheel 10 are the pair of similar foot skates 11 and 12. Skates 11 and 12 and its parts are identical in construction to each other except that one skate is adapted to be worn on the left foot, and the other skate is adapted to be worn on the right foot. FIG. 4 is an enlarged side view of one of the skates 11 which includes frame member 21 and a runner member 22. Frame member 21 is seen to have a front foot support member 23a and a heel support member 23b secured to a base 24. Front foot support member 23a and heel support member 23b are suitably designed to allow a person to releasably secure his foot therein. Runner member 22 includes a platform 25 hingedly secured to base 24 by hinge 26 at the forward ends thereof. As seen also in FIG. 5, platform 25 holds a suspension bracket 27 carrying fixedly positioned wheel shaft 28, and also holds another suspension bracket 29 carrying fixedly positioned wheel shaft 30.

Referring now to FIG. 6, there is shown therein an enlarged view of a skate wheel assembly showing wheel shaft 28 and one of wheels 31 which is typical of the other wheel assemblies. Skate wheel 31 as the other skate wheels is seen to have a concave outer riding surface 32 to match and therefor be guided by projecting boss 17a of track 17 when riding thereon as shown in FIG. 5. A toothed ratchet wheel 33 is keyed to shaft 28 by key member 33a. Ratchet wheel 33 is positioned between bearings 34a and 34b attached to shaft 28 to rotatively support said skate wheel 31. A pawl 35 with its engaging spring 35' has one end 35a fixedly secured to said skate wheel 31 within its central recess 36 inside skate wheel 31 by screw 37, and has its other free engaging end 35b dropping in the tooth spaces of ratchet wheel 33. Accordingly, said skate wheel 31 can only rotate on skate 28 in one direction indicated by arrow 38. Said toothed ratchet wheel 33 and its coacting spring-supported pawl 35 together with similar ratchet wheels and pawls in the other skate wheels 31 of foot skates 11 and 12 provide the holding means for allowing foot skates 11 and 12 to only move backwards with respect to the

circular tracks

17 and 19. An end cap 39 fits over the inner side opening of said skate wheel 31.

Retainer rings

40a and 40b fit in shaft recesses 41a and 41b respectively on both sides of skate wheel 31 to hold it in position. Another skate wheel is so assembled on shaft 28, and the skate wheels on shaft 30 are similarly assembled.

As seen in Flg. 5, each skate has two guide members extending therefrom and being positioned within the alignment slots in gyral wheel 10 to align each skate with their respective bosses projecting from the gyral wheel. Skate I1 is typical and has two guide members seen to be rollers 42 rotatable at the ends of brackets 43 secured on opposite sides of platform 25 in between wheels 31. Rollers 42 are positioned within the alignment slots such as slots 17' and 19 and they do not contact gyral wheel 10 when skate wheels 31 ride on the tracks formed by its boss projections, but will guide the return of said skate wheels when they are lifted off their tracks.

In order to operate the open wheel device of this invention, gyral wheel 10 will initially be held vertically on the ground as seen in the figures. Due to gravity, its foot skates l1 and 12 will then freely roll on its

circular tracks

17 and 19 to their lowest position at the bottom of gyral wheel 10. The person 13 operating the wheel device will occupy the same by inserting his feet in

support members

23a and 23b of skates 11 and 12 with his body in standing position inside open wheel 10.

The occupant will then raise one skate to clear its track and move it forward guided by its guide members 42 extending from brackets 43 to a higher position on its track. In this position, the rear end of frame member 21 will move away from runner member 22 as seen in FIG. 1 to enable the forwarddirected foot to be conveniently raised. Thereupon the occupant will shift his weight forward and press down on the raised skate causing it to engage its track and roll backwards thereon towards said bottom position. Gyral wheel 10 will then be moved and begin to rotate in a forward direction with the occupant maintaining his upright position. The occupant will 3 then raise the other skate and make another similar forward stride to repeat this movement. Thereafter, the occupant can alternately raise one foot then the other to continue the described action. The occupant this continues to make forward strides as in walking and then rolling back causing the open wheel device to roll in a forward direction. It will be realized that the rolling speed can be varied by the occupant by changing his so-called walking movement when operating the wheel device by changing the length and rate of his forwardmoving strides.

ln order to steer the open wheel device, the occupant will increase the length of his forward stride of one foot and decrease it on the other. Gyral wheel will then turn on its curved transverse riding surface 14 towards the side of the increases stride in order to turn gyral wheel 10 in that direction. It will be noted that the arms of the occupant 13 are free to assist in shifting his weight to further aid in propelling and turning the rotating gyral wheel. When the occupant desires to stop the gyral wheel then he will stop his forward strides. As the skate wheels are then locked since they cannot rotate forward with respect to their circular tracks, the weight of the occupant will press down on the circular tracks and oppose the forward movement of the gyral wheel and bring it to a stop.

It will be realized that with suitable practice, an occupant will be able to propel the open gyral wheel in a forward direction at varying desired speeds, to steer it in either direction and further to stop or brake the open gyral wheel in order to provide for his enjoyment, sport, or exercise.
