Form changing toy

Abstract

A form changing toy includes a moving part, a rotating part, a first stopper, a motor, and a holding mechanism. The rotating part is configured to move the moving part in first and second directions. An operation direction of the moving part is changed between the first and second directions at an inflection point of the rotating part. The rotation of the rotating part is configured to stop rotating in a first rotation direction when the rotating part rotating contacts the first stopper. The holding mechanism is configured to hold the moving part in a first state at a location between an inflection point and the first stopper, and to release the holding when the rotating part starts rotating in a second rotation direction opposite to the first rotation direction after the stopping at the first stopper.

What is claimed is: 
     
         1 . A form changing toy, comprising:
 a moving part being configured to change a form thereof between first and second states,   a rotating part being connected with the moving part,   a first stopper being configured at a first position;   a motor being configured to rotate the rotating part, and   a holding mechanism being configured to hold releasably the moving part in the first state,   the rotating part being configured to move the moving part in first and second directions, an operation direction of the moving part being changed between the first and second directions at an inflection point of the rotating part,   the moving part being in the first state at the inflection point,   the rotation of the rotating part being configured to stop rotating in a first rotation direction when the rotating part rotating contacts the first stopper,   the holding mechanism being configured to hold the moving part in the first state at a location between the inflection point and the first stopper,   the holding mechanism being configured to release the moving part when the rotating part starts rotating in a second rotation direction opposite to the first rotation direction after the stopping at the first stopper.   
     
     
         2 . The form changing toy according to  claim 1 , wherein
 the rotating part is a crank including slide plate,   the crank is connected to the moving part via a slide plate being configured to move reciprocally, and   the crank and the slide plate constitute a portion of a double slider crank mechanism.   
     
     
         3 . The form changing toy of according to  1 , wherein
 the rotating part is a crank including a link being configured to be rotated by rotation of the crank, and   the moving parts, the crank, and the link constitute a portion of a lever crank mechanism.   
     
     
         4 . The form changing toy according to  claim 3 , further comprising
 a second stopper being configured at a second position, wherein   the link stops by contacting the second stopper.   
     
     
         5 . The form changing toy according to  claim 1 , further comprising
 a spring being configured to urge the moving part to render the moving part in the first state.
