Simulated Walking Toy

Abstract

A toy simulating a walking or crawling creature comprising, a drive wheel assembly with at least a drive wheel, and a plurality of shafts that are eccentrically configured with respect to the main rotational axis of the drive wheel. A plurality of limbs are loosely coupled to said drive wheel through the plurality of shafts. The joint end of a limb is loosely coupled to a shaft so the limb can freely pivot around the shaft. A pair of left and right limbs coupled to a shaft further comprise at least a rotation stop that reciprocally restrain the rotational movement of the paired limbs. The terminal tip ends of limbs extend outward and downward to make contact with a surface continuously or temporarily through a rotation cycle of the drive wheel assembly. The limbs slide linearly and reciprocally on a surface as the drive wheel assembly is rotated.

Having thus described one form of the invention in some detail, what is claimed is: 
     
         1 . A drive wheel assembly comprising:
 a first and second drive wheels;   said first drive wheel is operatively coupled to a first shaft;   said second drive wheel is operatively coupled to a second shaft;   a third shaft is operatively coupled to said first and second shafts; and   at least a limb operatively coupled to each said shaft.   
     
     
         2 . The drive wheel assembly of  claim 1 , wherein said first drive wheel is rotatable with said second drive wheel along a common rotational axis. 
     
     
         3 . The drive wheel assembly of  claim 2 , wherein each said shaft is eccentric to said rotational axis. 
     
     
         4 . The drive wheel assembly of  claim 3 , wherein said first, second, and third shafts are offset at different angles from said rotational axis. 
     
     
         5 . The drive wheel assembly of  claim 4 , wherein a first pair of limbs is operatively coupled to said first shaft. 
     
     
         6 . The drive wheel assembly of  claim 5 , wherein a second pair of limbs is operatively coupled to said second shaft. 
     
     
         7 . The drive wheel assembly of  claim 6 , wherein a third pair of limbs is operatively coupled to said third shaft. 
     
     
         8 . The drive wheel assembly of  claim 7 , each said pair of limbs further comprises a rotation stop. 
     
     
         9 . The drive wheel assembly of  claim 8  further comprises a first tracking groove integrated to said first drive wheel. 
     
     
         10 . The drive wheel assembly of  claim 9  further comprises a second tracking groove integrated to said second drive wheel. 
     
     
         11 . A drive wheel assembly comprising:
 a drive wheel;   a plurality of shafts;   a plurality of limbs;   said drive wheel is operatively coupled to said shafts; and   each said limb is operatively coupled to at least one of said shafts.   
     
     
         12 . The drive wheel assembly of  claim 11 , wherein said shafts are coupled eccentrically to said drive wheel. 
     
     
         13 . The drive wheel assembly of  claim 12 , wherein at least two said limbs are coupled to each said shaft. 
     
     
         14 . The drive wheel assembly of  claim 13 , wherein said two limbs further comprise at least a rotation stop. 
     
     
         15 . The drive wheel assembly of  claim 14  further comprises a tracking groove integrated to said drive wheel. 
     
     
         16 . A walking toy device comprising:
 a driving wheel,   a plurality of shafts; and   a plurality of limbs paired in horizontally opposed directions.   
     
     
         17 . The walking toy device of  claim 16 , further comprises a link. 
     
     
         18 . The walking toy device of  claim 17 , further comprises a tracking groove. 
     
     
         19 . The walking toy device of  claim 18 , further comprises a rotation stop. 
     
     
         20 . The walking toy device of  claim 19 , further comprises a stabilizer.
