Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to yo-yos.

[0002]

[Prior art]

 In a conventionally known yo-yo, a pair of left and right disk-shaped side bodies 1 and 2 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 type in which the base end of the operation cord 4 was merely attached to the portion between the two, that is, the type having no rotating weight in the yo-yo according to the present invention. For this reason, there were dislikes 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 is devised to add fun to the action when playing.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, a yo-yo according to the present invention comprises a pair of left and right disc-shaped side bodies 1, 2 slightly separated from each other, and the centers thereof are fixed to both ends of a short axis 3 so as not to rotate. The base end of the operation cord 4 is attached to the portion between the left and right bodies 1 and 2 in the above, and the left and right side bodies 1 and 2 have hollow chambers 7 centered on the boss portions 5 and 6 of the short shaft 3. , 8 are provided, and rotatable arms 9 are inserted into the left and right hollow chambers 7, 8, and the center portion thereof is rotatably supported on the bosses 5, 6, and both ends of the rotatable arms 9 are provided. It has weights 10 and 11 fixed thereto, is equipped with a coil spring 20 for silencing, and is provided with a pin 27 for regulating the rotation angle of the rotary arm 9.

[0005]

[Effect of the invention]

 Since the yo-yo according to the present invention has the above-described configuration, when the main body 12 including the left and right bodies 1 and 2 and the short axis 3 is operated by the operation cord 4, the yo-yo is lowered from ascended or ascended. When changing to lowering, the rotation of the rotating arm 9 with the weights 10 and 11 and the rotation of the main body 12 cause instantaneous misalignment due to the inertia of the arm 9, and it is interesting to perform an action different from the conventional yo-yo. In the present invention, the centrifugal force of the weights 10 and 11 changes the rotation of the main body 12, for example, the speed, operation, and the like, and the game cannot be obtained as a whole by the conventional type. The effect of the coil spring 20 for silencing is that the rotating arm 9 does not make a rattling sound, so that there is no discomfort. Is intended to allow, also those that can abut small play switch is of what is was in failure to be made smoothly to rise from the lowered by reaction by the pin 27 and the rotary arm 9.

【Example】

 In the embodiment shown in the figure, a pair of left and right disk-shaped side bodies 1 and 2 made of transparent hard plastic are slightly separated from each other, and the centers thereof are fixed to both ends of the short axis 3 so as not to rotate. The base end of the operation cord 4 is attached to the portion between the right side bodies 1 and 2, and the recesses 13 are provided on the outer surfaces of the left and right side bodies 1 and 2, and the opening of each recess 13 is made of transparent plastic. The cover 14 is fitted by the locking claw 16 and the stepped portion 17 to form the hollow chambers 7 and 8 around the bosses 5 and 6 of the short shaft 3, and the bosses 5 and 6 are formed. A dish-shaped body 18 having a double peripheral wall is rotatably fitted to the double-walled body, and a coil spring 20 for noise reduction is fitted into the double peripheral wall 19 of the dish-shaped body 18 so that both ends of the coil spring 20 are in contact with the bottom surface of the recess 13. The bottom wall 2 of the dish-shaped body 18 is lightly pressed against the bottom of the double peripheral wall 19. The center point of the outer surface of the plate 14 is lightly pressed against a pointed projection 22 previously provided at the center of the inner surface of the lid 14 so as to prevent the plate-shaped body 18 from generating a rattling sound due to play. On both sides of the shaped body 18, projecting plate portions 23 and 24 are integrally protruded to form the rotating arm 9, and holes 25 and 26 are provided at the tip end portions of the projecting plate portions 23 and 24 of the rotating arm 9 to form these. The spherical metal weights 10 and 11 are fitted and fixed in the holes 25 and 26 so that they cannot be pulled out. Further, the tip portions of the protruding plate portions 23 and 24 abut on the outer periphery of the bottom surface of the concave portion 13 to rotate the rotary arm 9. Four protrusion pins 27 for regulating the corners are provided in a four-sided arrangement.
