Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a yo-yo in the field of toys.

[0002]

2. Description of the Related Art In recent years, due to the yo-yo boom, children and the like have been operating yo-yos in towns, parks, and the like.

[0003] In addition, a yo-yo tournament and the like are held, various techniques and advanced techniques are performed, and efforts are made to learn these techniques.

[0004]

In order to operate the yo-yo, the operating thread must first be wound around the yo-yo. For this reason, the operating thread is frequently wound around the yo-yo. Since it was wound, it took a long time to wind.

Further, the upper end of the yo-yo operating thread is formed in a ring shape and inserted into a finger to be locked. It was difficult to fit.

[0006]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above points, and in order to solve the above-mentioned problems, in order to rapidly rotate a yo-yo body and wind an operating thread, a disk-shaped body is used. The present invention provides a yo-yo characterized in that a turning shaft portion is protruded from a central portion on the outside of the yo-yo body.

It is another object of the present invention to provide a yo-yo in which a turning shaft is projected so that the yo-yo rotates like a frame around the turning shaft.

Still another object of the present invention is to provide a yo-yo in which a finger belt provided with a thread locking portion is detachably wound around a finger so that the upper end of the operating thread of the yo-yo body can be easily hooked on the finger.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The yo-yo according to the present invention is characterized in that a rotating shaft portion is disposed at the center of the outside of a disk-shaped yo-yo main body in order to quickly rotate the yo-yo main body and wind an operating thread. I have.

As shown in FIG. 1, the yo-yo 1 has a left and right disc-shaped yo-yo body 2 having an inner central portion connected by a connecting shaft 3 such as a screw. The yoyo 1 is turned by supporting the turning shaft portions 4 on both sides between fingers, so that the operation thread 5 can be quickly wound around the thread winding portion 6 of the connecting shaft portion.

As shown in FIGS. 1 and 2, a small bearing 8 having a cylindrical body 7 protruding therefrom is attached to the center of the yo-yo body 2. A substantially Z-shaped groove 9 is opened in each part, and a protrusion 12 having a round head 11 is fitted into the cylindrical body 7 through an elastic material 10 such as a coil spring having a predetermined elastic force. At the same time, the locking pin 13 is inserted into the groove 9 and attached to the cylindrical body 7.
The fitting body 14 is fitted as a mountain-shaped cross-section for attaching the turning shaft 4 to the yo-yo body 2 in a good manner.

When the protruding portion 12 is disengaged from the locking groove 15 at the lower end of the Z-shaped groove 9 against the elastic member 10, the fitting body 14 fitted to the yo-yo body 2 as shown on the right side of FIG. The locking pin 13 is locked in the locking groove 16 at the upper end of the groove 9.

Further, the protruding portion 12 is made to have a Z
When it is removed from the locking groove 16 at the upper end of the U-shaped groove 9 and retracted inward, the round head 11 is retracted from the fitting body 14 fitted to the yo-yo body 2 as shown on the left side of FIG.

In this way, as shown in FIG.
Can be wound around the hand-wound portion 6 by rotating the yo-yo 1 with the fingers held between fingers, or by rotating the yo-yo 1 around the hand-wound portion 6 with fingers or the like as shown in FIG.

The outer peripheral portion of the yo-yo main body 2 formed as described above is formed into an annular concave portion 17 having a semicircular cross section as shown in FIG. To protect the yo-yo 1 by absorbing shock when the yo-yo 1 hits the ground or the like. Also, by changing the dimensions of the annular body 18,
The outer diameter can be easily adjusted to the size of the hand, and the ring 18 is made transparent or colored so that the yo-yo 1 can be made colorful or differentiated from others.

Further, in order to easily attach the upper end of the operation thread 5 of the yo-yo 1 to a finger, as shown in FIGS. 5 and 6, a rubber material, a soft resin material, a leather material, a cloth material or the like having a predetermined width is used. Finger belt 19 for engaging velvet fasteners such as strips and strips
Can be appropriately wound in accordance with the size of the finger. Numeral 20 denotes a detachable joint position-adjustable connecting belt for single and double use, and reference numeral 21 denotes a cushion material such as urethane foam or rubber, which can protect a finger.

As shown in FIG. 5 and FIG.
9, a locking groove 22, 2 or 2 for the operation thread 5 in the form of a radial groove or a pen point groove.
3 is attached, and the upper end of the operation thread 5 is
By being inserted into the 23 locking grooves 24 and 25, the finger belt 19 can be easily locked. Locking tools 22, 23
Can be either one or both.

In particular, as shown in FIGS. 5 and 6, the locking tool 22 is slightly tall so that the operating thread 5 can be wound around the shaft 26 at the back of the locking tool 22. Length adjustment is made easy.

[0019]

FIGS. 3 and 4 show examples of use of the present invention. In FIG. 3, when the protrusion 12 of the pivot shaft portion 4 of the yo-yo 1 projects outward, and the protrusion 12 is supported by the thumb and the middle finger of the hand and the yo-yo 1 is supported between the fingers, the yo-yo body 2 is moved. The operation thread 5 can be quickly and easily wound around the thread winding portion 6 by turning.

In addition to being able to operate the yo-yo 1 in the conventional manner, it is also possible to play the yo-yo 1 by putting it on a finger or the like via the revolving shaft portion 4 as shown in FIG.

It should be noted that the above-mentioned turning shaft portion 4 is
Can be retracted and used, and if the protruding portion 12 is retracted, it can be safely stored in a pocket or the like.

As shown in FIGS. 5 and 6, one or two turns of the finger belt 19 are wound around the finger, and the operation thread 5 is locked in the locking grooves 24, 25 of the locking tools 22, 23. The finger belt 19 can be perfectly attached to the finger of the infant or child, and the operation thread 5 can be attached without causing pain in the finger. Further, the yo-yo 1 can be operated by being wound around the locking member 22 so that the operation thread 5 has a length suitable for the user.

The pivot shaft portion can be provided so as to protrude only on one side of the yo-yo body, or not to protrude on both sides.
In addition, appropriate modifications can be made within the scope of the present invention, such as attachment with a screw or a structure protruding like a tip or knock of a mechanical pen or ballpoint pen.

[0024]

As described above, according to the present invention, in order to quickly rotate the yo-yo body and wind the operating thread,
By arranging the pivot shaft portion in the center of the outer side of the disk-shaped yo-yo body, the yo-yo body can be quickly and easily pivoted through the pivot shaft portion, and the operation thread is quickly moved to the thread winding portion of the connection shaft portion. Can be wound.

Further, by arranging the revolving shaft portion of the yo-yo body so as to protrude and be retractable, the operating thread can be quickly and easily wound on the protruding revolving shaft portion as described above. It can be rotated and played, and the swivel shaft can be retracted and safely stored in a pocket or the like.

Furthermore, a finger belt provided with a thread locking portion is detachably wrapped around the finger so that the upper end of the operating thread of the yo-yo body can be easily hooked on the finger, so that it can be wound around the finger of an infant or child. The operation thread can be attached without causing pain on the fingers by attaching the finger belt perfectly. Further, the yo-yo can be operated by wrapping the operating thread so as to have a length suitable for a user such as an infant.
