[57] ABSTRACT A toy comprising a vertical shaft securable at its lower end in the ground; an axle secured to the top end of the shaft and extending upward therefrom; a horizontal circular disc having a seat and spaced handles on the top surface; a hub disposed rotatably about the axle and secured at its top end to the center of the bottom surface of the disc and a pull cord fastened at one end to the hub.

1 Claim, 3 Drawing Figures PATENIEU JAM S1914 llllll! ROTATABLE CORD DRIVEN PASSENGER CARRYING DISC SUMMARY OF THE INVENTION My invention is directed toward a childs toy in which a youngster can sit upon a horizontal disc and be spun around first in one direction then in the reverse direction as another child first unwinds a coiled cord and allows the cord to rewind, and then unwinds the rewound coil.

To this end, the disc, which is circular, supports a seat and spaced handles which can be grasped by hand or foot. A vertical hub is secured at its top end to the bottom surface of the disc at the center. A vertical post or shaft extends upward out of the ground and is surmounted by a vertical axle. The hub is rotatable about the axle. One end of the cord is secured to the hub and the cord can be wound or coiled about the outer surface of the hub.

In use, with the cord coiled, one child sits in the seat and is properly braced with use of the handles. One or more children then pull on the cord and unwind it whereby the disc spins around and the child is likewise spun. If slack is left in the unwound coil, continued spin will cause the unwound coil to be rewound to a lesser degree. The children can then pull to unwind the rewound coil and cause the direction of spin to reverse.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings:

FIG. 1 is a side elevation of my invention in use;

FIG. 2 is a plan thereof; and

FIG. 3 is an exploded view of some of the parts used in my invention.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Referring now to FIGS. 1-3, a horizontal circular disc has a seat 12 and spaced handles 14 for supporting hands and feet secured to the top surface. A vertical hub 16 is secured at its top end to the center ofa flat circular plate 18 which in turn is secured to the bottom surface of disc 10 at the center thereof. The hub is secured at its bottom end to a smaller parallel plate 20 which acts as a shoulder. The hub itself is shaped into a vertical truncated cone having an inner hollow bore 22 of like shape. The base of the cone is at the bottom end. One end of cord 24 can be secured to the outer surface of the cone and the cord can be wound therearound.

A vertical post or shaft 26 has its bottom end buried in the ground 28 and extends upward therefrom. A hollow sleeve 30 is secured to the top end of the shaft. A second horizontal like plate 20' is secured at its center to the top end of the sleeve. A vertical axle 32 is secured to the center of plate 20' and extends upward. The axle also defines a truncated cone conforming to the shape of bore 22, but being somewhat smaller. The axle extends within the bore with plates 20 and 20 in adjacent engagement. The plates can be lubricated if desired. The hub is freely rotatable about the axle and when rotated rotates the disc accordingly.

The invention can then be operated as previously described.

While I have described my invention with particular reference to the drawings, such is not to be considered as limiting its actual scope.

Having thus described'this invention, what is asserted as new is:

l. A pull and spin passenger carrying disc comprismg:

a vertical shaft fixedly secured at its lower end;

an axle secured to the top end of the shaft and extending upward therefrom;

a horizontal circular disc having a seat and spaced handles on the top surface;

a flat circular plate secured to the bottom surface of the disc at the center thereof;

a vertically positioned hub shaped into a vertical truncated cone and having an inner hollow bore of like shape having its top end secured to the center of said flat circular plate and its bottom end secured to the inner edge of a horizontally positioned shoulder ring;

the bottom end of the axle being secured to the inner edge of a like horizontally positioned shoulder ring with the axle itself defining a vertical truncated cone conforming to the shape of the bore of the hub, but being somewhat smaller, so that the hub and its shoulder ring fits over and is rotatably supported by the axle and its shoulder ring; and

a pull cord fastened at one end to the hub and windable about the outside of the hub between the plate and shoulder ring whereby an occupant sitting on the seat and braced by the handles may be repeatedly spun by an operator repeatedly pulling on the free end of the pull cord until it unwinds and then allowing the cord to go slack so that momentum rewinds the pull cord in the opposite direction.
