Abstract

A top which can facilitate the coupling of a winder is provided. The toy top comprises: a blade; a shaft of which one end is fixed to a lower portion of the blade; a pinion to be inserted and coupled to the middle of the shaft; and a shaft holder capable of accommodating the pinion-coupled shaft in a rotating manner, wherein the shaft holder comprises winder connectors (for rotating the pinion. Particularly, the winder connectors comprise: a cut portion for contacting a part of a first portion of a winder on a lateral side; and a guide groove for allowing a second portion extended from the first portion of the winder to be stopped at stepped protrusions inside the cut portion so as to prevent the second portion from being separated from the lateral side when a part of the first portion of the winder is contacted to a lateral side and then the winder is moved to the lateral side.

Claims

1. A toy top comprising:

a blade;

a shaft fixed to the lower portion of the blade at one end thereof;

a pinion fitted to the intermediate portion of the shaft;

a shaft holder configured to allow the shaft to which the pinion is fitted to be rotatably housed thereinto; and

winder connectors formed on both sides of the shaft holder to rotate the pinion,

wherein each winder connector comprises;

a cut portion adapted to allow a first portion of a winder to partially come into contact with the lateral side thereof; and

a guide groove adapted to allow a second portion extended from the first portion of the winder to be locked onto stepped protrusions formed from the cut portion so as to prevent the second portion from being escaped from the lateral side thereof when the winder is moved thereto in the state wherein the first portion of the winder partially comes into contact with the lateral side thereof.

2. The toy top according to claim 1, wherein the first portion of the winder comprises:

a first support rod having a lower thickness than the width of the cut portion of each winder connector; and

wings adapted to come into contact with both sides of the external surface of the cut portion, and the second portion of the winder comprises;

a second support rod extended linearly from the first support rod; and

a rack gear having a higher thickness than the second support rod, the rack gear being formed in the opposite direction to the portion where the wings of the first portion are formed in such a manner as to be engaged with the pinion.

3. The toy top according to claim 1, wherein the rack gear is locked on the stepped protrusions formed on the inner sides of the cut portion to prevent the second portion of the winder from being escaped from the lateral side of the winder connector.
