A yoyo capable to be electrically accelerated when held by hands

Abstract

A yoyo capable to be electrically accelerated when held by hands, characterized in that, it comprises two spinning bodies (1), a connector (2) connecting the two spinning bodies (1) as a whole, side shaft sleeves (3) provided at center positions of outer sides of the spinning bodies (1), an electrical acceleration mechanism provided inside the spinning bodies (1), and a bearing (4) disposed between the two spinning bodies (1) for winding a yoyo string. The electrical acceleration mechanism is connected to the spinning bodies (1). By pressing the side shaft sleeves (3), the electrical acceleration mechanism operates and thus drives the spinning bodies (1) to spin simultaneously. The side shaft sleeves (3) can be pressed to start spinning and accelerating the spinning bodies (1); when the spin speed is high enough, grab the yoyo string and then release the yoyo; the player can then have sufficient time to perform various yoyo tricks. Accordingly, even a short player can play the yoyo. Further, the yoyo can once again be accelerated when its spin speed is too slow. When the side shaft sleeves (3) are not grabbed, the electrical acceleration mechanism stops operating while the yoyo will still continue to spin due to inertia, thereby providing much fun in playing the yoyo. The yoyo has a wide range of utility satisfying the playing needs of kids and children.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a yoyo, and more specifically relates to a yoyo capable to be electrically accelerated when held by hands.[0002]Due to the constraints of the retracting and bearing systems of a conventional yoyo, a conventional yoyo cannot be played by a short player because length of the yoyo string is proportional to the player's height. When a taller player releases the yoyo, the yoyo is provided with a sufficiently large acceleration zone for the yoyo to accelerate to a spin speed enough for the player to complete different yoyo tricks. However, when a short player releases the yoyo, the acceleration zone is too tiny and thus the yoyo cannot spin with a speed enough to perform yoyo tricks. Nowadays, the market provides a kind of electrical yoyo, wherein an electrical switch inside the yoyo is connected due to centripetal force when the yoyo is released via a yoyo string, and a motor will then drive a main shaft via gears to rotat...

Benefits of technology

[0003]In view of the aforesaid disadvantages now present in the prior art, the present invention provides a kind of yoyo capable to be electrically accelerated when held by hands. The yoyo according the present invention can provide much fun in playing and can be accelerated when it is being held by hands.

[0012]The present invention comprises two side shaft sleeves extending out of the center positions at the outer sides of the spinning bodies and an electrical acceleration mechanism provided in the spinning bodies, whereas the electrical acceleration mechanism is connected with the spinning bodies, and by pressing the side shaft sleeves, the electrical acceleration mechanism operates and thus drives the spinning bodies to spin. When the idle rotation speed of the yoyo is slow, the side shaft sleeves can be pressed to accelerate spinning of the yoyo so that players are provided with sufficient time to perform more yoyo tricks; alternatively, when the yoyo is not spinning, the side shaft sleeves can be pressed to start spinning the spinning bodies, and when the spin speed is high enough, grab the yoyo string and then release the yoyo to perform various yoyo tricks. Accordingly, even a short player can play the yoyo. The yoyo of the present invention has a wider range of utility satisfying the playing needs of kids and children. Also, the yoyo spinning speed can be accelerated when it is too slow, and when the side shaft sleeves are not grabbed, the electrical acceleration mechanism stops operating while the yoyo will still continue to spin due to inertia and will gradually reduce in speed and eventually stop spinning. Therefore, the yoyo can provide the excitement of competing with time and allow players to play in the form of competitive matches. At the same time, the ways of playing the yoyo are increased, thereby providing much fun in playing the yoyo. Further, since the electrical acceleration mechanism is designed to be formed by the power supply mechanism and the drive mechanism whereas the power supply mechanism is disposed in one spinning body and the drive mechanism is disposed in another spinning body, weight balance of the two spinning bodies can be ensured so as to maintain the center of gravity of the yoyo at a central axis position. Accordingly, when the yoyo is driven by the yoyo string to spin, the yoyo can be ensured to spin steadily and also with a longer spinning time. In summary, the yoyo of the present invention has a smart design and provides various ways of playing the yoyo. Players can have much fun in playing the yoyo. The yoyo of the present invention satisfies the playing needs of short players and allows players to create their own ways of playing the yoyo so that the yoyo can remain to be an appealing toy even after a long period of time.

Problems solved by technology

Due to the constraints of the retracting and bearing systems of a conventional yoyo, a conventional yoyo cannot be played by a short player because length of the yoyo string is proportional to the player's height.

However, when a short player releases the yoyo, the acceleration zone is too tiny and thus the yoyo cannot spin with a speed enough to perform yoyo tricks.

This kind of design consumes too much energy and lacks the excitement of competing with time because the yoyo will keep spinning within a certain period of time and so it is difficult to play the yoyo in form of competitive matches.

A conventional yoyo is therefore not well received by kids and children.
