Top toy set and top toy

Abstract

A top toy being is provided. The top toy is used together with a field including a step part and an acceleration rail being configured on the step part. The top toy includes a rotating shaft extending in an axial direction, a rotor being concentric with the rotating shaft, and a ride-over part being configured on the rotating shaft above the rotor. The rotating shaft includes a landing part on a bottom end thereof. The rotor is configured to engage with the acceleration rail. The ride-over part includes an axially symmetrical sliding contact surface. The sliding contact surface has a diameter increasing as extending upwardly in the axial direction.

What is claimed is: 
     
         1 . A top toy set, comprising:
 a field including a step part and an acceleration rail being configured on a step part; and   a top toy including a rotating shaft extending in an axial direction, a rotor being concentric with the rotating shaft, and a ride-over part being configured on the rotating shaft above the rotor, the rotating shaft including a landing part on a bottom end thereof, the rotor being configured to engage with the acceleration rail,   the ride-over part including an axially symmetrical sliding contact surface, the sliding contact surface having a diameter increasing as extending upwardly in the axial direction.   
     
     
         2 . A top toy being used together with a field including a step part and an acceleration rail being configured on the step part, the top toy comprising:
 a rotating shaft extending in an axial direction;   a rotor being concentric with the rotating shaft; and   a ride-over part being configured on the rotating shaft above the rotor, the rotating shaft including a landing part on a bottom end thereof, the rotor being configured to engage with the acceleration rail,   the ride-over part including an axially symmetrical sliding contact surface, the sliding contact surface having a diameter increasing as extending upwardly in the axial direction.   
     
     
         3 . The top toy according to  claim 2 , wherein
 when the top toy stands upright and when the rotor and the acceleration rail are engaged, a first length from a point where the rotating shaft abuts a floor to a top end of the step part is greater than a second length from a bottom end of the landing part to a bottom end of the ride-over part.   
     
     
         4 . The top toy according to  claim 2 , wherein
 the rotor is a gear, and   the guide rail is a rack.   
     
     
         5 . The top toy according to  claim 4 , wherein
 the gear is tapered with a diameter expanding facing downward.   
     
     
         6 . The top toy according to  claim 2 , wherein
 the rotor is a roller, and   a surface of the acceleration rail is smooth surface.   
     
     
         7 . The top toy according to  claim 6 , characterized in that the gear is a roller that is tapered with the diameter expanding as extending downward. 
     
     
         8 . The top toy according to any of  claim 2 , wherein
 the landing part is made of rubber.
