Toy top

Abstract

A toy top includes a body, a shaft portion, a movable component and a biasing member. The movable component includes at least a portion of the body and is movable upward and downward along the rotational axis of the toy top. The biasing member urges the movable component upward or downward. The movable component has a circumferential face that flares away from the biasing direction of the biasing member as the circumferential face recedes from the rotational axis. When the circumferential face collides with an opponent toy top, the movable component moves against a biasing force of the biasing member in a direction opposite to the biasing direction, and then the movable component is urged by resilience of the biasing member, so that the opponent toy top is moved in the biasing direction.

         2 . The toy top according to  claim 1 , wherein the circumferential face of the movable component surrounds an entire circumference of the body. 
     
     
         3 . The toy top according to  claim 1 , wherein the biasing member urges the movable component upward, and the circumferential face of the movable component flares downwardly as the circumferential face recedes from the rotational axis. 
     
     
         4 . A toy top having a rotational axis, comprising:
 a body which rotates about the axis;   a component which is movable upward and downward relative to the body and the rotational axis of the toy top; and   a biasing member which urges the movable component in a biasing direction which is either upward or downward relative to the axis,   wherein when the movable component collides with an opponent toy top, the movable component moves opposite the biasing direction, and then the movable component is urged by the biasing member to move the opponent toy top in the biasing direction.   
     
     
         5 . The toy top according to  claim 4 , wherein the movable component forms a circumferential periphery of the toy top. 
     
     
         6 . The toy top according to  claim 4 , wherein
 the biasing member urges the movable component upward, and   the movable component includes a circumferential face that flares downwardly as the circumferential face recedes from the axis.   
     
     
         7 . The toy top according to  claim 4 ,
 wherein the body includes a plate to which the movable component is connected,   wherein the biasing member is connected between the movable member and the plate, and   wherein the plate is connected to a shaft portion of the body.   
     
     
         8 . The toy top according to  claim 4 , wherein the biasing member is a plurality of equally-spaced coil springs. 
     
     
         9 . The toy top according to  claim 4 ,
 wherein the body includes an upper plate and a lower plate spaced from the upper plate and connected to a shaft portion of the body,   wherein the movable component is positioned between the upper and lower plates.   
     
     
         10 . The toy top according to  claim 9 , wherein the biasing member is connected between the movable component and one of the top plate and the bottom plate. 
     
     
         11 . The toy top according to  claim 4 , wherein the movable component has a peripheral surface that is angled away from the biasing direction. 
     
     
         12 . The toy top according to  claim 11 , wherein the movable component has a circumference and the peripheral surface is continuous along the circumference. 
     
     
         13 . The toy top according to  claim 11 , wherein the movable component has a circumference and the peripheral surface is interrupted by spaces along the circumference. 
     
     
         14 . The toy top according to  claim 4 , wherein the movable component is a plurality of movable components positioned on the body, and the biasing member is a plurality of biasing members positioned on the body, each biasing a respective one of the movable components. 
     
     
         15 . A toy top having a rotational axis, comprising:
 a body having a first member and a second member; and   a shaft portion operatively connected to the body;   wherein the second member is movable upward and downward relative to the first member relative to the axis; and   a biasing member between the first and second members which urges the second member in a biasing direction which is either upward or downward relative to the axis,   wherein the second member has a peripheral surface that is angled away from the biasing direction,   wherein when the second member collides with an opponent toy top, the second member moves opposite the biasing direction, and then the second member is urged by the biasing member to move the opponent toy top in the biasing direction.   
     
     
         16 . The toy top according to  claim 15 , wherein the peripheral surface surrounds an entire circumference of the second member. 
     
     
         17 . The toy top according to  claim 16 , wherein the biasing member urges the second member upward, and flares downwardly as the peripheral surface recedes from the axis. 
     
     
         18 . The toy top according to  claim 15 , wherein the biasing member is a plurality of equally-spaced coil springs.
