Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotating toy called a yo-yo, and more particularly, to a rotating toy capable of generating a sound when rotating.

[0002]

2. Description of the Related Art Conventionally, a rotating toy of this type has a pair of disk-shaped rotating bodies arranged at an interval, and a center of each rotating body is connected with a connecting shaft. Is attached. Hook one end of the string wrapped around the connecting shaft on the finger of the hand, release the rotating body strongly, release the string from the connecting shaft that rotates with the rotating body, and when the string is fully extended, The string is wound back by the inertia force and returned to the hand, and the above operation is repeated to play.

[0003] The rotating toy has long been popular as a simple toy, but since the rotating operation of the rotating toy is monotonous, the rotating toy may be tired of playing for a long time. In view of the above, various types of rotating toys have been proposed. For example, a flashing type yo-yo (see Japanese Utility Model Laid-Open No. 60-99987) in which a built-in light bulb or a light-emitting diode flashes or turns on as a rotating toy rotates, or a yo-yo with an electronic music box that can generate an electronic sound such as an electronic music box ( Various rotary toys (yo-yos) have been proposed such as the one described in Japanese Utility Model Application Laid-Open No. 60-106687).

[0004]

However, a rotating toy that blinks or lights up the light bulb or the light emitting diode, or a rotating toy that generates sound by an integrated circuit, has a constant brightness or monotony regardless of the rotating speed of the rotating body. However, there is a problem that only a small sound can be generated and the change is poor.

[0005] In addition, the rotating toy electronically constructed in such a manner requires a battery, various circuits, and electronic parts such as a speaker to be built in the rotating body, and the arrangement of the parts such as the battery is inappropriate. In this case, the balance of the rotating body may be impaired, so that the rotating body cannot be smoothly rotated, and there is also a problem that the original play of the rotating toy cannot be performed.

[0006] Furthermore, when a rotating toy incorporating electronic parts as described above is subjected to a shock due to rough handling, the electronic parts easily cause poor contact and do not operate correctly.
There was also a problem that a failure easily occurred.

The present invention has been made to solve such a problem. That is, the object of the present invention is to incorporate a sound-generating structure having a simple structure, and to be able to exchange these sound-generating structures. It is an object of the present invention to provide a rotating toy that can be played with interest and without getting tired by variously changing the tone and the intensity of the sound.

[0008]

According to the rotating toy of the present invention, a pair of rotating bodies (2) are arranged at intervals and a connecting shaft (3) for connecting the central portions of both rotating bodies (2). The intermediate portion is rotatable with respect to a string (4) wound around the coupling shaft (3) and released from the coupling shaft (3) and a coupling shaft (3) projecting in opposite directions from the center of the rotating body (2). Rod-shaped pendulum (5) with a weight (6) at one end attached to
A substantially bowl-shaped sounding body (8) fixed to the tip of the coupling shaft (3) and formed on the inner peripheral surface thereof with a projection (7) to which a weight (6) of the pendulum (5) is struck. And a projection (7) of a sounding body (8) that rotates together with the rotating body (2) strikes against a weight (6) of the pendulum (5) swinging around the coupling shaft (3). The sounding body (8) is configured to be sounded, thereby providing a rotating toy.

In the structure of the invention, one end of the string (4) wound around the connecting shaft (3) of the rotating toy (1) is hooked on a finger of the hand, and the rotating toy (1) is strongly thrown and thrown. When the cord (4) is released from the connecting shaft (3) that rotates together with (2) and the cord (4) is completely extended, the cord (4) can be wound back by the inertia of the rotating body (2) into the hand. it can.

The sounding body (8) that rotates together with the rotating body (2) has a protrusion (7) whose weight (6) of the pendulum (5)
Is struck and struck. The pendulum (5) is rotatably mounted at an intermediate portion with respect to the coupling shaft (3) and has a weight (6) at one end thereof, so that it follows the rotation of the coupling shaft (3). So that it does not rotate. Thus, the projection (7) of the rotating sounding body (8) can be hit on the weight (6) of the pendulum (5) thus oscillating, and a sound is generated from the sounding body (8). Can be done.

Further, a substantially disk-shaped resonance plate (13) can be attached between the rotating body (2) and the sounding body (8). Further, it is preferable that the sounding body (8) is detachably attached to the coupling shaft (3) projecting to both sides from the center of the both rotating bodies (2).

By attaching the resonance plate (13) in the sounding body (8), the sound generated by the sounding body (8) can be resonated and resonated to generate different timbres.
By replacing and attaching the sounding body (8) having a different material, plate thickness, hardness or shape to the rotating body (2), it is possible to enjoy a different tone and a change in this tone further. it can.

[0013]

Preferred embodiments of the present invention will be described below with reference to the drawings. In the drawings, common members are denoted by the same reference numerals, and redundant description is omitted. FIG.
FIG. 1 is an exploded sectional view showing a first embodiment of a rotating toy of the present invention. FIG. 2 is a side view showing the pendulum. 3A and 3B show a sounding body, wherein FIG. 3A is a front view seen from the inside thereof, and FIG. 3B is a side sectional view. The rotating toy 1 of the present invention comprises:
A pair of rotating bodies 2, a coupling shaft 3 that couples both rotating bodies 2,
Two generally bowl-shaped sounding bodies 8 formed on the inner peripheral surface thereof with a string 4 wound around the coupling shaft 3 located between the two rotating bodies 2 and a projection 7 to which the weight 6 of each pendulum 5 is struck.
And with.

The rotator 2 is, for example, a disc-shaped member made of plastic or metal. The two rotators 2 are arranged at a predetermined interval, and the center of both rotators 2 is connected to the connecting shaft 3.
Are combined. As shown in FIG. 1, the left rotating body 2 is integrally formed with a boss 2a having an insertion hole at the center thereof, so that the amount of protrusion of the boss 2a directly serves as a gap between the two rotating bodies 2. The gap between the two rotating bodies 2 only needs to have such an interval that the string 4 wound around the coupling shaft 3 smoothly winds and separates. For example, if the interval is too large, the rotating body 2 may not be able to be rotated in a well-balanced manner. Conversely, if it is too narrow, the string 4 cannot be wound smoothly. The connecting shaft 3 does not necessarily have to be a separate member from the rotating body 2, and may be formed integrally with either rotating body 2. If the coupling shaft 3 is integrally formed with the rotating body 2, the assembly can be easily completed simply by inserting the coupling shaft 3 into the through hole of the other rotating body 2.

The two ends of the connecting shaft 3 connecting the two rotating bodies 2 are largely projected outward from the center of each rotating body 2. A pendulum 5 having the same shape is rotatably attached to each of the coupling shafts 3. These pendulums 5 consist of two thin elongated plates 9 with a connecting shaft 3
The intermediate portion is rotatably attached to the coupling shaft 3 so as not to rotate following the rotation of. A pin 10 is attached to one end of the pendulum 5 so as to sandwich the ring-shaped weight 6 so that the ring-shaped weight 6 can be eccentric. In this way, the weight 6 is attached with sufficient play to the pin 10 because the weight 6 is instantaneously separated from the projection 7 when the weight 6 is hit on the projection 7 of the sounding body 8. This is to prevent the vibration of the sounding body 8 from being stopped.

The sounding body 8 is, for example, a substantially bowl-shaped member made of metal and has a projection 7 formed on the inner peripheral surface thereof. As shown in FIG. 3, an example in which two protrusions 7 are formed on one sounding body 8 has been described.
Is not limited to two, and one or three or more can be formed. The sounding body 8 is formed by fixing a screw 12 from a screw through hole 11 formed in a center portion thereof to a screw fixing hole formed in a tip of the coupling shaft 3. By removing the screw 12, the sounding body 8 can be replaced with a sounding body 8 having a different structure. For example, the sound quality and the sound of the sound can be obtained by replacing the sounding body 8 with a material or hardness such as iron or brass, the sounding body 8 with a changed plate thickness, or the sounding body 8 with a changed protrusion amount of the projection 6. It is possible to change the strength and the like in various ways. The timbre emitted from the sounding body 8 can be changed also by the difference in the rotation speed of the rotating body 2.

FIG. 4 is an explanatory diagram showing the positional relationship between the pendulum and the sounding body during rotation. The rotating toy 1 configured as described above holds one end of the string 4 wound around the connecting shaft 3 on a finger of the hand, and throws the rotating body 2 strongly to release the rotating body 2 from the connecting shaft 3 rotating with the rotating body 2, When the string 4 is completely extended, the string 4 can be wound and returned into the hand by the inertial force of the rotating body 2.

The sounding body 8 which rotates together with the rotating body 2
The projection 7 is hit against the weight 6 of the pendulum 5, and the sounding body 8 can be sounded. Since the pendulum 5 is rotatably attached to the coupling shaft 3 and has a weight 6 at one end, even if the coupling shaft 3 rotates, it does not rotate following the rotation. ing. Then, the protrusion 7 of the rotating sounding body 8 is moved by the weight 6 of the swinging pendulum 5.
And the sounding body 8 is sounded. Therefore,
If the rotation of the rotating body 2 of the rotating toy 1 is faster, the speed of the sound is faster, and if the rotation is slower, the speed of the sound can be slower. You can play with interest and without getting tired.

FIG. 5 is a front sectional view showing a second embodiment in which a resonance plate is provided on the rotating toy of the present invention. In the second embodiment, a substantially disc-shaped resonance plate 13 can be attached between the rotating body 2 and the sounding body 8. By attaching the resonance plate 13 in the sounding body 8 in this manner, the sounds generated by the sounding body 8 can resonate with each other to generate different timbres.

FIG. 6 is a front view showing another embodiment of the rotating body provided with a plurality of through holes in the rotating body. Rotating body 2 of the present invention
Can be incorporated with a plurality of through holes 14. When the rotary body 2 has the through-holes 14 as described above, sounds emitted from the sounding body 8 can easily pass through these through-holes 14 to the outside through the gaps of the rotary body 2, and are rich in changes due to the action of air vibration and sound. It becomes hard to stay.

It should be noted that the present invention is not limited to the above-described embodiment, but has been described with reference to an embodiment of a structure in which the connecting shaft 3 is penetrated by the rotating body 2. Instead, it is also possible to use a structure in which the rotating body and the coupling shaft are integrally formed. Further, the shape of the pendulum 5 is not limited to a rod-like shape as shown in FIG. 2 and may be formed in a circular or substantially triangular shape. Therefore, various changes may be made without departing from the gist of the present invention. Can of course be added.

[0022]

As described above, the rotating toy of the present invention is
In the state of playing the conventional yo-yo, the string wound around the connecting shaft can be hung on the finger of the hand, the rotating body can be strongly thrown away to release the string from the connecting shaft, and the string can be wound back into the hand. The sounding body that rotates together with the rotating body has its protrusion struck against the weight of the pendulum, and can sound the sounding body several times while the string is fully extended.

The timbre emitted from the sounding body varies in tone and strength of the sound depending on the rotation speed of the rotating body, and the material, shape and the like can be variously changed by replacing the rotating body itself or the pendulum. Since it can be changed, there are excellent effects such as being able to play with interest and without getting tired.
