Description

[Detailed description of the invention] This invention rotates the hollow body of the music box toy and the rotating base in the opposite direction, and also allows the various figures to move along with the trajectory of the rotating base and always rotate in a constant direction independently of the rotating base. This invention relates to a music box toy characterized by a rotating central figurine.

Conventionally, in this type of device, a doll, etc. on a rotating base that rotates in a fixed position rotates and flips as the rotating base rotates.
In most cases, the central figurine rotates together with the rotating base, which has the disadvantage that the movements are stylized and lack interest.

The present invention eliminates these drawbacks, and embodiments thereof will be described below with reference to the drawings.

The hollow main body 1 has a circular hole 1a in the center of the upper surface, and a bottom plate 2 is detachably fixed to the bottom surface.

A music box 3 is fixed to the bottom plate 2, and a spring-wound knob 3a penetrating the bottom plate 2 and serving also as a leg is provided on the music box 3.

A gear 4 meshing with the music box gear 3b of the music box 3 in a bevel-shaped manner has teeth carved on the outer edge of its bottom surface, and a vertical shaft 6 on its top surface.
is provided protrudingly, and the center of a rotating base 5 having a diameter slightly smaller than the circular hole is fixed to the upper end of the vertical shaft 6.

The vertical shaft 6 is supported by a support piece 7, and the gear 4 is meshed with the music box gear 3b by a spring washer 8 at a suitable pressure.

The rotating base 5 projects slightly above the circular hole 1a of the hollow main body 1, and a pin 9 is provided on the eccentric portion of the vertical shaft 6 to project from the rotating base 5.

The separately provided rotating base 10 has a concave portion 10a and a convex portion 10 on the outer periphery.
A transparent disc 11 is integrally fixed to the surface of the transparent disc 11, and various figures 12 such as a plurality of dolls are attached to the surface of the transparent disc 11. Loosely fit the center hole 13 of the pin 9 into the center hole 13 of the pin 9.

That is, the rotating base 10 is slidably placed on the rotating base 5.

At the top of the pin 9, apart from the rotation base 10, there is a central figure 1.
A stop pin 15 is provided on the outer edge of the upper surface of the hollow body 1 at a height and position that reaches the side surface of the convex portion 10b of the rotating base 10.

The present invention is constructed as described above, and its usage will be described below.

When the spring-wound knob 3a, which also serves as the leg of the music box 3, is wound, the bottom plate 2 and the hollow body 1 will rotate counterclockwise when viewed from the front.

Also, since the music box gear 3b rotates in the direction of the clock hands, the rotation base 5, rotation base 10, and central figure 14 rotate in the same direction via the gear 4 and the vertical shaft 6.

That is, the rotating base 10, the central figure 14, etc. are rotating in the opposite direction to the hollow body 1.

Therefore, the eccentric pin 9 of the rotating base 5 is the stop pin 1.
5, and the distance between the pin 9 and the stop pin 15 becomes shorter than the distance between the pin 9 and the tip of the protrusion 10b of the rotation base 10, the side surface of the tip of the protrusion 10b of the rotation base 10 comes into contact with the stop pin 15, and the rotation begins. However, the rotating base 10 slides on the rotating base 5 and is pushed back by the rotation of the stop pin 15 and pin 9 due to the rotation of the hollow body 1, reducing the contact angle, and then the rotating base 5 As the distance between the pin 9 and the stop pin 15 decreases due to the rotation of the hollow body 1, the rotating base 10 moves to the stop pin 15 side, and when the distance between the pin 9 and the stop pin 15 becomes the shortest, that is, the stop pin When the deep part of the recess 10b of the rotating base 10 reaches the stop pin 15
The pushing back of the rotating base 10 to the rear is completed, and the contact angle is also minimized.

Thereafter, as the hollow body 1 and the rotating base 5 continue to rotate and the pin 9 and the stop pin 15 are successively separated, the side surface of the convex portion 10b of the rotating base 10 and the stop pin 15 slide together and move in the rotation direction. The stop pin 15 reaches the tip of the protrusion 10b, and the pin 9 and the protrusion 1 of the rotating base 10
When the distance between the pin 9 and the stop pin 15 becomes longer than the distance between the tip of the convex portion 10b, the tip of the convex portion 10b comes off from the stop pin 15, and the rotating base 10 rotates in conjunction with the rotating base 5 again.

That is, when the side surface of the convex portion 10b of the rotating base 10 comes into contact with the stop pin 15, the rotating base 10 touches the stop pin 1.
5 and pin 9 temporarily stop the rotation and are pushed back slightly to reduce the contact angle between the stop pin 15 and the rotating base 10 to change the direction of the rotating base, and to change the direction of the rotating base 10. The rotation is delayed from the rotation of the rotating base 5, and then the stop pin 15 and the convex portion 10b are removed and rotated again, which is repeated.

Moreover, the central figure 14 rotates around the outer periphery of the vertical shaft 6 at a constant speed along with the rotating base 5, regardless of the movements of the hollow body 1 and the rotating base 10.

As described above, in the music box toy of the present invention, after the stop pin 15 and the convex part 10b of the rotating base come into contact with each other, until they separate again, various figurines such as dolls mounted on the rotating base will move. It operates in the same way, and its movements are more complex, cute, interesting, and interesting than conventional products.

In addition, the central figurine rotates at a constant speed on the outer periphery of a vertical axis, separate from the hollow body and the rotating base. It stands out, and the overall movement is very atmospheric.

Note that the rotating base 10 and the transparent disc 11 may be fixed together or provided freely, or the transparent disc may be omitted and a figurine such as a doll may be directly mounted on the rotating base 10. be.

The shape of the rotating base is not limited to the shape shown in FIG. 4, as long as it has a concavo-convex portion on its outer periphery.

Furthermore, by changing the distance between the stop pin 15 and the vertical shaft 6, the number of times the stop pin 15 and the rotating base 10 come into contact can be increased or decreased.
