Description

SPECIFICATION Wheeled toy The present invention relates generally to a wheeled toy. It particularly concerns a mobile toy in which rotation of a part associated therewith is induced as the toy, for example a toy automobile, travels along a linear path, the arrangement being such that dice placed on said associated part will turn over and round to cause the same effect as throwing dice.

Dice games always arouse people's interest; thus there are many games that use dice. Conventionally, the dice are cast by hand or thrown from a dice box or a similar conveyance. This invention provides a novel mobile toy in which dice can be turned over and around on a rotary member driven by the wheels of the mobile toy until the motion of the toy, for example a toy automobile, ceases.

An object of the invention is to provide a mobile toy which includes a rotatable member such as a plate driven by the wheels of the mobile toy.

It is further object of the present invention to provide a mobile toy in which dice can be tossed on a rotatable dice supporting member or table such as a plate driven by the wheels of the mobile toy.

In accordance with the invention, a wheeled toy comprises a frame including wheels mounted thereon, a rotatable member, and a driving mechanism by which the rotation of the wheels imparts rotation and mementum to the rotatable member.

Fig. 1 is a perspective view of an embodiment of the mobile toy according to this invention; Fig. 2 is a perspective view of an embodiment of the mobile toy as shown in Fig. 1 with the fitted body removed; Fig. 3 is an exploded view of the driving mechanism of the embodiment as shown in Fig. 1 and Fig. 2; Fig. 4 is a top view of another embodiment of the mobile toy according to this invention; Fig. 5 is a longitudinal section of the embodiment shown in Fig. 4, in which the wheels are indicated by dottes lines; Fig. 6 is a schematic view of the chassis frame including the driving mechanism of the embodiment shown in Fig. 5.

Referring now to Fig. 1, the numeral 1 designates a mobile toy including a transparent housing 4 secured as the roof thereof, and wheels, the rear wheels being designated as 7, 7 and the front wheels as 8, 8, which are journaled on the ends of rear axle 7a and front axle (not shown) respectively.

In Fig. 2 and Fig. 3, the chassis frame 3 of the mobile toy is formed of plastic or similar material, including a base plate 11 and a rise-up portion 15a.

Moreover, a U-shaped frame 10 is mounted on the chassis frame 3 to cover the rise-up portion 15a yet separate from it, so as to provide necessary mounting surface.

A rotatable plate 5 is designed to be rotated by the rear wheels 7, 7 through the driving mechanism. As detailedly shown in Fig. 3, a crown wheel 9 fixedly mounted on the rear axle 7a, which drives a pinion 13, the pinion 13, supported vertically to the axle 7a, and imparts the motion to a pair of flywheels 14, 14 fixedly mounted on the pinion 13, such that, the flywheels 14, 14 rotate as a whole with the pinion 13 to store and absorb energy from the rotation momentum developed when rotating the wheels 7, 7 on the floor or any supporting surface upon which the mobile toy is placed to be moved. Thus the mobile toy can continuously proceed a fairly long distance when pushing it forward.

The pinion 13 also drives a gear 17 which is connected with a rod 16 which fixedly supports circular plate 5. As a result, the circular plate 5 will be driven to rotate with the wheels 7, 7 lasting for a period of time depending on the momentum of flywheels 14, 14.

The assembly of the chassis frame 3 and driving mechanism is detailedly shown in Fig. 2. The pinion 13 and flywheels 14, 14 are disposed between the base plate 11 and the rise-up portion 15a. The shank 13a is rotatably projected through the riseup portion 15a and base plate 11 respectively.

The rotatable plate 5 is journalled on the supporting frame 10 and fixedly connected with the rod 16 which terminates in gear 17.

By virtue of the rotation of rotatable plate 5, when dice 6, 6 are placed on the plate, they will turn over and around as long as the rotation continues; consequently, the effect of casting or throwing dice can be obtained by operating the moving mobile toy according to this invention.

Another embodiment is shown in Fig. 4 through 6. In this embodiment, the chassis frame of the mobile toy includes an additional U-shaped frame 2. The front wheels 22, 22 drive a crown wheel 9, and the crown wheel is engaged with a pinion 13 journalled in an inclined ma ner between the opposite side walls 24, 25. On the pinion 13, there are a pair of flywheels 14, 14 mounted and rotated as a whole with the edge portion abutting against a rotatable plate 5; the rotatable plate 5 is supported by a horizontally extending portion 311 of the mounted body 31 and capable of turning about the axle 52 thereof as the pinion 13 is being driven. In the alternative arrangement, dice 6, 6 placed on the rotatable plate 5 will turn over and around just as in the first embodiment.

1. A wheeled toy comprising a frame including wheels mounted thereon; a rotatable member adapted to have placed dice thereon, being rotatably supported on said frame; and transmission means capable of transmitting the rotation of said wheels to said rotatable member.

2. A wheeled toy as claimed in claim 1, wherein said transmission means comprises a flywheel.
