Abstract

(57) [Summary] [PROBLEMS] To provide a new yo-yo with a device for adding fun to the action when playing and other devices. SOLUTION: A pair of left and right disc-shaped side bodies are slightly separated from each other, and the center thereof is fixed to both ends of a short shaft so as not to be rotatable, and the ring-shaped body is rotatable around the outer periphery of a portion between the left and right bodies on the short axis. And a spring for attaching the base end of the operation cord to the ring-shaped body and pressing the one end surface of the ring-shaped body to a pressing surface formed inside one side body on the short axis. The side body and the ring-shaped body rotate integrally when the braking force generated by the pressing by the spring becomes larger than the prescribed rotational force of the side body, and when the braking force is smaller, the side body Rotate in a state separated from the ring-shaped body.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to yo-yos.

[0002]

[Prior art]

 Conventionally, this type of yo-yo has a pair of left and right disc-shaped side bodies that are slightly separated from each other, the center of which is fixed to both ends of the short axis so that they cannot rotate, and is located between the left and right bodies on the short axis. The type in which the base end of the operation cord was merely attached, that is, the type having no rotating weight in the yo-yo according to the present invention was used. Because of this, there was a dislike that the action in the game was monotonous and lacked interest.

[0003]

[Problems to be solved by the invention]

 The purpose of the present invention is to provide a new yo-yo that has been devised to add fun to the action when playing and other devises.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the yo-yo according to the present invention has a pair of left and right disc-shaped side bodies slightly separated from each other, and the centers thereof are fixed to both ends of a short shaft so that they cannot rotate. A ring-shaped body is rotatably fitted to the outer periphery of the point between them, the base end of the operation string is attached to this ring-shaped body, and one end face of the ring-shaped body is attached to the inside of one side body on the short axis. The side body and the ring-shaped body are wound when a spring that is pressed against the pressing surface formed on the side body is wound, and when a braking force generated by the pressing by the spring becomes larger than a specified rotational force of the side body. When the body is small, it rotates with the side body separated from the ring-shaped body, and formed on one end face of the ring-shaped body and inside one side body. And a concave portion and a convex portion which are engaged with each other so as to be able to jump over each other. A hollow chamber centered on the boss of the short axis is provided at the center, a rotating arm is inserted into the hollow chamber, and the center is rotatably supported on the boss, and weights are fixed to both ends of the rotating arm. It consists of

[0005]

[Effect of the invention]

 Since the yo-yo according to the present invention has the above-described configuration, the rotation of the disk-shaped side body is fast at the initial stage when the entire operation cord is released and the left and right disk-shaped side bodies are at the lowest position, and the ring-shaped body is formed. When the rotation of the side body continues due to the short axis spinning around and the rotation of the side body slows down near the end, the braking force by the spring wins and the short axis spins in the ring-shaped body. As the side body and the ring-shaped body rotate together, the operation string is wound up to form an auto return, which has a high degree of certainty in the auto return operation and high playability. The yo-yo according to claim 3, wherein a rotating arm with a weight is used when changing from lowering to ascending or from ascending to descending when the body composed of the left and right bodies and the short axis is operated by the operation cord. The arm rotates with the arm The momentary shift caused by the inertia causes an interesting action that is different from the conventional yo-yo, and the centrifugal force of the weight changes the rotation of the main body, for example, speed and movement. However, as a whole, it has a favorable effect of exhibiting the fun of the game which cannot be obtained by the conventional type.

【Example】

 In the first embodiment shown in FIGS. 1 to 5, a pair of left and right disc-shaped side bodies 1 and 2 made of transparent hard plastic are slightly separated from each other, and their centers are fixed to both ends of a short axis 3 so as not to rotate. The base end of the operation cord 4 is bound via a binding member 15 at a position between the left and right bodies 1 and 2 on the short axis 3, and the disc-shaped side bodies 1 and 2 and the short axis 3 and the binding member 15 are as follows. That is,

The disc-shaped side bodies 1 and 2 are provided with recesses 13 on the outer surface thereof, and a transparent plastic lid 14 is fitted into the opening of each of the recesses 13 by locking with locking claws 16 and step portions 17. Thereby, hollow chambers 7 and 8 are formed around the bosses 5 and 6 of the short shaft 3, and a dish-shaped body 18 having a double peripheral wall is rotatably fitted to the bosses 5 and 6. At the same time, a coil spring 20 for noise reduction is fitted into the double peripheral wall portion 19 of the dish-shaped body 18, and both ends of the coil spring 20 are lightly pressed against the bottom surface of the recess 13 and the bottom surface of the double peripheral wall 19. Lightly pressing the center point of the outer surface of the bottom wall 21 of the dish-shaped body 18 in advance against a pointed projection 22 provided at the center of the inner surface of the lid 14, whereby the dish-shaped body 18 sounds rattling due to play. And protrude from both sides of the dish-shaped body 18. The projecting plate portions 23 and 24 are integrally protruded to form the rotating arm 9, and holes 25 and 26 are provided at the end portions of the projecting plate portions 23 and 24 of the rotating arm 9, and these holes 25 and 26 have spherical shapes. The metal weights 10 and 11 are fitted and fixed so that they cannot be pulled out, and the tip portions of the protruding plates 23 and 24 abut on the outer periphery of the bottom surface of the recess 13 to regulate the rotation angle of the rotary arm 9. The four protruding pins 27 are provided in four directions.

The short axis 3 is composed of a main body 32 composed of a large-diameter rod 29, a medium-diameter rod 30, and a small-diameter screw rod 31, and a cap nut having the same outer diameter as the large-diameter rod 29. The small-diameter screw rod 31 is screwed into the female screw 34 of the cap nut 33 and the main body 32 and the cap nut 33 are connected to each other. A large-diameter rod 29 and a bag-shaped nut 33 are non-rotatably fitted into shaft holes 36 and 37 provided in the left and right disk-shaped side bodies 1 and 2.

The binding member 15 is a ring-shaped body in which a U-shaped groove 38 for attaching the operation cord 4 is provided on the outer periphery and an L-shaped groove 39 for attaching the spring is also provided on the inner periphery. It is rotatably fitted on the outer circumference.

The binding member 15 is lightly pressed to the inner end of the cap nut portion 33 by a coil spring 40 wound around the constricted portion 35, and the connecting member 15 is provided on both sides of the pressing surface. The plurality of concave portions 41 and convex portions 42 that are jumpably engaged with each other are rotated together with the left and right disk-shaped side bodies 1 and 2. That is, when the rotation of the left and right disk-shaped side bodies 1 and 2 is faster than a predetermined value, and the acting force of the coil spring 40 is smaller than the jumping force, the left and right disk-shaped side bodies 1 and 2 are rotated. 1 and 2 continue rotating in a state where they are separated from the binding member 15, and when they become large, they are locked and rotated together.

The second embodiment shown in FIG. 6 does not have the concave portion 41 and the convex portion 42, and the other configuration is almost the same as the first embodiment.
