Crawling toy

Abstract

A crawling toy includes a shell body showing a special design and defining a receiving space, in which a pivot shaft is transversely mounted; and two side wheels rotatably mounted to two ends of the pivot shaft. Each of the side wheels has a plurality of angularly equally spaced adherent sections providing predetermined adhesion force and elasticity. The adherent sections separately located at two ends of the side wheels are arranged in a staggered manner. When the crawling toy is positioned on an upper end of an inclined or a vertical surface, an overall weight of the crawling toy forms a driving force, which cooperates with the two side wheels rotating at the two ends of the pivot shaft to cause the adherent sections to alternately adhere to and separate from the surface, bringing the toy to move like a crawler.

1 . A crawling toy, comprising:
 a shell body having an outer surface showing a special design, and defining at a bottom portion a receiving space, in which a pivot shaft is transversely mounted;   a plurality of side wheels being rotatably mounted to two ends of said pivot shaft, and having a plurality of angularly equally spaced adherent sections each; said adherent sections providing predetermined adhesion force and elasticity; and said adherent sections separately located at two ends of said pivot shaft are arranged in a staggered manner.   
   
   
       2 . The crawling toy as claimed in  claim 1 , wherein said pivot shaft is enclosed in a hollow shaft cover, and said shaft cover having two ends formed into two through holes, into which two inserts separately axially inward extended from inner centers of said two side wheels are inserted. 
   
   
       3 . The crawling toy as claimed in  claim 2 , wherein said shaft cover includes two stop plates separately radially outward extended from the two through holes, so that said two stop plates are pressed against and close areas at inner sides of said two side wheels around said two inserts. 
   
   
       4 . The crawling toy as claimed in  claim 1 , wherein each of said side wheels includes a plurality of angularly equally spaced and radially outward extended supports, and said adherent sections being separately connected to outer ends of said supports.
