Benefits of technology

[0008] It is an object of the present invention to provide an improved electromechanical yo-yo that solves the above-described problem by forcibly causing a

Problems solved by technology

However, the rotation of the toy body reaches a maximum speed at the lowermost end, and sometimes if the rotational force becomes weak, the string cannot be rewound around the shaft body and the yo-yo cannot be made to rise and return to the user when the toy body is left as it is, so that youngsters and beginners who cannot successfully control the timing at which to make the yo-yo rise to rewind the string become unable to continuously play with the yo-yo because the

Abstract

A yo-yo includes a toy body formed by a pair of housings connected by a rotatable connecting shaft. The toy body includes a detecting unit that automatically detects the rotation of the toy body and a motor that rotates the connecting shaft on the basis of the detection result of the detecting unit. The detecting unit detects the direction of rotation of the toy body and actuates the motor to rotatingly drive the connecting shaft in the same direction as the direction of rotation of the toy body.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates generally to a yo-yo, and more particularly to a yo-yo configured to sustain selective rotation with a controllable motor system. [0003] 2. Description of Related Art [0004] Generally, a traditional yo-yo includes a toy body that is formed by connecting a pair of discoid rotating bodies (housings) with a shaft body. A string is wound around the shaft body, so that when the toy body is lowered, the toy body rotates as the wound string is unwound, and when the toy body rises, the string is rewound around the shaft body due to the rotational force of the toy body. Thus, the yo-yo is an instrument of play that can repeatedly move up and down. [0005] However, the rotation of the toy body reaches a maximum speed at the lowermost end, and sometimes if the rotational force becomes weak, the string cannot be rewound around the shaft body and the yo-yo cannot be made to rise and return to the use...
