Manual traveling toy

Abstract

A manual traveling toy includes a toy body, at least one wheel that projects downward further than a bottom surface of the toy body, is in contact with a traveling surface, and rotates about an axle shaft, a swing part that is swung in directions about a swing vertical shaft supported at a rear end side position in a traveling direction of the toy body to apply external force to the toy body and move the toy body in directions that cross the traveling direction, and a rotation-swing converting mechanism that converts rotary movement of the at least one wheel into swinging movement of the swing part.

What is claimed is: 
     
         1 . A manual traveling toy comprising:
 a toy body;   at least one wheel that projects downward further than a bottom surface of the toy body and is configured to contact a traveling surface and to rotate about an axle shaft;   a swing part that is fixed to a swing vertical shaft supported at a rear end side position in a traveling direction of the toy body so that the swing part is swingable about the swing vertical shaft; and   a rotation-swing converting mechanism that converts rotary movement of the at least one wheel into swinging movement of the swing part.   
     
     
         2 . The manual traveling toy according to  claim 1 , wherein
 the wheel is heavier than the swing part, and   the swing part is at a position to which the swing part swings at maximum toward at least one side, a center of gravity of the swing part is positioned outside a range of a width between outer edges positioned at both ends of a contact surface of the at least one wheel in a direction orthogonal to the traveling direction.   
     
     
         3 . The manual traveling toy according to  claim 1 , wherein
 a distance from the center of gravity of the swing part to the swing vertical shaft is shorter than a distance from a position at which an entire length of the swing part is divided into equal lengths to the swing vertical shaft.   
     
     
         4 . The manual traveling toy according to  claim 1 , wherein
 the at least one wheel and part of the rotation-swing converting mechanism are arranged side by side in the direction orthogonal to the traveling direction.   
     
     
         5 . The manual traveling toy according to  claim 1 , wherein
 the at least one wheel comprises two wheels supported apart on an axis identical to the axle shaft and part of the rotation-swing converting mechanism is arranged between the two wheels.   
     
     
         6 . The manual traveling toy according to  claim 1 , wherein
 in the contact surface of the at least one wheel, a central portion of the width in the direction orthogonal to the traveling direction projects further than the both ends.   
     
     
         7 . The manual traveling toy according to  claim 1 , wherein
 the at least one wheel comprises a base and a covering material that covers the base and forms the contact surface, and frictional force caused between the covering material and an identical traveling surface is larger than frictional force caused between the base and the identical traveling surface.   
     
     
         8 . A manual traveling toy comprising:
 a toy body;   at least one wheel that projects downward further than a bottom surface of the toy body and is configured to contact a traveling surface and to rotate about an axle shaft;   a swing part that is fixed to a swing vertical shaft supported at a rear end side position in a traveling direction of the toy body so that the swing part is swingable about the swing vertical shaft;   a rotation-swing converting mechanism that converts rotary movement of the at least one wheel into swinging movement of the swing part; and   two sideward fall preventing members that project downward further than the bottom surface of the toy body by a first height and are positioned on both sides more outside than most outer surfaces of the at least one wheel, the most outer surfaces of the at least one wheel being positioned at both ends of the at least one wheel in a direction orthogonal to the traveling direction, the first height being smaller than a second height from a contact surface of the at least one wheel to the bottom surface of the toy body.   
     
     
         9 . The manual traveling toy according to  claim 8 , wherein
 the toy body comprises a forward fall preventing member that projects downward further than the bottom surface at a position on a more front side than the at least one wheel in the traveling direction.   
     
     
         10 . The manual traveling toy according to  claim 8 , wherein
 the toy body comprises a rearward fall preventing member that projects downward further than the bottom surface at a position on a more rear side than the at least one wheel in the traveling direction.
