Toy gyroscope

Abstract

A toy gyroscope comprises a casing; a toy object which is rotatably mounted in the casing; and an unbalanced driving element which is rotatably mounted in the casing; wherein a free wheel transmission is provided between the unbalanced driving element and the toy object, having a direction of rotary actuation.

What is claimed is:  
     
         1 . A toy gyroscope comprising 
 a casing ( 4 );    a toy object ( 11 ) which is rotatably mounted in the casing ( 4 ); and    an unbalanced driving element ( 8 ) which is rotatably mounted in the casing ( 4 );    wherein a first free-wheel transmission ( 15 ) is provided between the unbalanced driving element ( 8 ) and the toy object ( 11 ), having a direction of rotary actuation ( 21 ).    
     
     
         2 . A toy gyroscope according to  claim 1 , wherein a counterpart driving element ( 9 ) is provided, which is rotatably mounted and which is connected to the unbalanced driving element ( 8 ) such that it rotates in the opposite direction thereof.  
     
     
         3 . A toy gyroscope according to  claim 2 , wherein, between the counterpart driving element ( 9 ) and the toy object ( 11 ), a second free-wheel transmission ( 18 ) is provided, having the same direction of rotary actuation ( 21 ).  
     
     
         4 . A toy gyroscope according to  claim 1 , wherein the moment of inertia of the unbalanced driving element ( 8 ) exceeds the moment of inertia of the toy object ( 11 ).  
     
     
         5 . A toy gyroscope according to  claim 2 , wherein the unbalanced driving element ( 8 ) and the counterpart driving element ( 9 ) are connected to each other by a planet wheel connection ( 10 ).  
     
     
         6 . A toy gyroscope according to  claim 2 , wherein the unbalanced driving element ( 8 ) and the counterpart driving element ( 9 ) are connected to each other such that, upon complete rotation of the unbalanced driving element ( 8 ), the counterpart driving element ( 9 ) makes a complete rotation in the opposite direction.  
     
     
         7 . A toy gyroscope according to  claim 2 , wherein the toy object ( 11 ) and the unbalanced driving element ( 8 ) are mounted for rotation about a joint axis of rotation ( 5 ).  
     
     
         8 . A toy gyroscope according to  claim 7 , wherein the counterpart driving element ( 9 ) is mounted for rotation about the same axis of rotation ( 5 ).  
     
     
         9 . A toy gyroscope according to  claim 1 , wherein the casing ( 4 ) has a casing bottom ( 2 ) which is substantially convex.  
     
     
         10 . A toy gyroscope according to  claim 1 , wherein the first free wheel transmission ( 15 ) has a gear ring ( 16 ) which is connected to the toy object ( 11 ) and cooperates with a pawl ( 17 ) that is joined to the unbalanced driving element ( 8 ).
