Tooth-meshing rolling toy set

Abstract

A tooth-meshing rolling toy set includes at least one curved carrier member and at least one rolling member. The at least one curved carrier member has a first surface and an opposite second surface; and the first and the second surface all are provided with a toothed structure having a plurality of teeth. The at least one rolling member includes a rolling body having a peripheral surface extending around the rolling body to define a closed geometric loop having a curved surface. The peripheral surface is also provided with a toothed structure having a plurality of teeth that mesh with the teeth of the toothed structure on the curved carrier member, such that the at least one rolling member can roll on the first surface or the second surface of the at least one curved carrier member through meshing with the at least one curved carrier member.

What is claimed is: 
     
         1 . A tooth-meshing rolling toy set being characterized in comprising:
 at least one curved carrier member having a first surface and an opposite second surface; and the first and the second surface all being provided with a toothed structure having a plurality of teeth; and   at least one rolling member having a rolling body; the rolling body having a peripheral surface extending around the rolling body to define a closed geometric loop having a curved surface; the peripheral surface being also provided with a toothed structure having a plurality of teeth that mesh with the teeth of the toothed structure on the curved carrier member, such that the at least one rolling member can roll on the first surface or the second surface of the at least one curved carrier member through meshing of the teeth of the toothed structures on the two members.   
     
     
         2 . The tooth-meshing rolling toy set according to  claim 1 , characterized in that the at least one curved carrier member is provided at two opposite ends between the first surface and the second surface with a first engaging section and a second engaging section; the second engaging section being complementary corresponding to the first engaging section in shape, such that a plurality of curved carrier members can be serially connected together to form a carrier structure through engagement of the second engaging section of one curved carrier member with the first engaging section on another curved carrier member; and the at least one rolling member being able to roll on the carrier structure through meshing of the teeth of its toothed structure with the teeth of the toothed structure of the carrier structure. 
     
     
         3 . The tooth-meshing rolling toy set according to  claim 2 , characterized in that the carrier structure includes curved carrier members having different widths. 
     
     
         4 . The tooth-meshing rolling toy set according to  claim 2 , characterized in that the first engaging section is configured as a slide ridge and the second engaging section is correspondingly configured as a slide slot. 
     
     
         5 . The tooth-meshing rolling toy set according to  claim 2 , characterized in that the carrier structure has an overall configuration including a plurality of curves bent in different directions. 
     
     
         6 . The tooth-meshing rolling toy set according to  claim 2 , characterized in that the carrier structure has an overall configuration like a hook structure. 
     
     
         7 . The tooth-meshing rolling toy set according to  claim 2 , characterized in that the carrier structure has an overall configuration as a circle, and that the at least one rolling member is able to roll on an inner side of the carrier structure through teeth meshing. 
     
     
         8 . The tooth-meshing rolling toy set according to  claim 2 , characterized in that a plurality of rolling members is provided, and some of the rolling members that are not in use can be stacked below an end of the carrier structure to raise the end to a relatively higher position. 
     
     
         9 . The tooth-meshing rolling toy set according to  claim 1 , characterized in that the at least one curved carrier member is elastic and is provided with a plurality of serially arranged through slots.
