Description

[Detailed Description of the Invention] The present invention relates to a rotating toy with a music box that moves the toy body in multiple directions.

Conventionally, a rotating toy in which multiple toy bodies were mounted on a rotary plate rotated by a music box and rotated in forward and reverse directions while rotating the whole in one direction was developed in 1983-94799.
It has been proposed in the Publication No.

However, in this method, a ring-shaped raceway was provided on the raceway plate with outer raceway rods and inner raceway rods each having a triangular cross-section divided into two or several parts, with slanted walls facing each other, and a large cylindrical raceway attached to the shaft rod of the toy body. Because the small rotor is engaged with the raceway rod, the toy body only rotates forward and backward and the whole body rotates in one direction, making it uninteresting. When switching, the rotor gets caught on the end of the raceway rod, putting a heavy load on the music box, and with the rotor riding on the raceway rod, there are drawbacks such as the rotation of the toy body becoming uncertain.

The purpose of this invention is to raise multiple toys without rotating, rotate and lower, rotate in forward and reverse directions, and move multiple toys so as not to place a heavy load on the music box while the music box is playing. To propose a rotating toy with a music box that arouses the interest of the viewer by making the entire body revolve in one direction.

The features of the present invention include a cam member that is integrally attached to the music box, an arc-shaped wall surface provided on the cam member that does not overlap inside and outside in the circumferential direction, an annular portion located between the walls and having continuous upper and lower surfaces, and a rotating portion of the cam member. a rotating member that is freely supported and rotationally connected to the music box; a rotating shaft that is supported by the rotating member so as to be able to move vertically and whose lower end is located on the annular portion; a circular rotating body that is fixed to the rotating shaft and contacts the wall surface; It consists of a toy body mounted on a shaft, and has a wall surface on the side of the annular portion other than the rising surface.

The present invention will be explained below with reference to illustrated embodiments. 1st
In the rotating toy with a music box shown in FIGS.
The drum 12 is rotated by a music box drive source that is fixed to the drum and is housed in the barrel, and the pin of the drum hits the diaphragm 13 to make the music box sound. The crown gear 15 rotatably attached to the cam member 2 is meshed and rotated, and this rotation connects the rotation center shaft 3 and the rotation member 4 via the intermediate transmission gears 16 and 17.
is rotated, and a plurality of rotating shafts 5 are fitted into the rotating member 4 so as to be rotatable and movable up and down.A circular rotating body 6 is fixed to the outer periphery of the lower end of the rotating shaft 5, and a toy object 7 is attached to the upper end. The rotating shaft 5 is rotated and moved up and down by the cam member 2.

As shown in FIGS. 2 to 4, the cam member 2 has a central boss portion 2a in which the rotation center shaft 3 is rotatably supported, and a round hole in the support portion in which the upper end of the support column 10 is fitted and supported. 2b, the elongated hole 2c, the fixed boss portion 2d of the support shaft 18 of the crown gear 15, and a plurality of sets of arc-shaped wall surfaces 2c and 2f that do not overlap inside and outside in the circumferential direction around the center boss portion 2a, and between the wall surfaces. It is formed of a jetty-like annular portion 2j as shown in FIG. 5, which is located on the bottom surface 2g of the roof and has a continuous ascending surface 2h and descending surface 2i.

As shown in FIG. 4, the rotation center shaft 3 has a disc 19, a spring washer 20, and the intermediate transmission gear 17 fitted onto the flange 3a of the rotation center shaft, and the upper rotation center shaft 3 is connected to the cam. It is fitted into the central boss part 2a of the member 2, an E-ring 21 is fitted onto the upper side of the rotational center shaft 3 to prevent it from coming off, and the fixing boss part 4a of the rotational member 4 is screwed and fixed to the upper end of the E-ring 21. There is.

The rotating member 4 has a fixing boss portion 4a for the central rotating shaft 3 on the lower surface of the center of the disc, a plurality of boss portions 4b above the annular portion 2j of the cam member 2 around the lower surface, and a plurality of boss portions 4b for fixing the central rotating shaft 3 on the lower surface of the center of the disk. Through hole 4 drilled in the center
The rotary shaft 5 is fitted into the through hole 4c.

The lower end spherical or curved surface 5a of the rotating shaft 5 rides on the annular portion 2J of the cam member 2, which continuously has an ascending surface 2h and a descending surface 2i, and is moved up and down. A plate 8 is fixed.

The circular rotating body 6 is made of an elastic material such as rubber and is formed into a cup shape with an upward opening and a flange 6a extending outward from the top as shown in FIG. , 2f, the rotating shaft 5 is rotated in forward and reverse directions, and when it receives lateral pressure from the walls 2e and 2f due to rotation, or when it receives lateral pressure due to rotation and descent, it is absorbed by the eccentricity and twisting of the collar portion 6a and the elastic body. The structure is such that the drive source is not overloaded.

The toy object 7 is formed in the shape of a doll, animal, artificial flower, or other object suitable for viewing purposes, and is simply represented as a cylinder in the drawing.

As shown in FIG. 4, the crown gear 15 is rotatably supported by a support shaft 18 together with an intermediate transmission gear 16, and is biased downward by a spring washer 24.
When the cam member 2 is supported on the support 10 by the screw 22, the round hole 2b, and the elongated hole 2c as shown in FIGS.
The meshing depth of the gear 14 fixed to the drum 12 can be adjusted, and even if there is sagging when the gear 14 and the crown gear 15 are formed by press working, the direction of sagging of the gears 14 and 15 can be specified. This simplifies the processing process and assembly work.

When the rotating toy with a music box is configured as described above and the winding key (not shown) is screwed onto the Zenmai shaft 23 protruding downward from the frame 1a of the music box 1 and the Zenmai is wound up, the drum 12 is rotated. When the music box 1 is played, the gear 14,
The rotating member 4 is rotated via the crown gear 15, the intermediate transmission gears 16 and 17, and the central rotating shaft 3, and when the drum 12 is rotated clockwise in FIG. 1, the rotating member 4 is rotated counterclockwise. 3 as shown in Figure 2
The state of the circular rotating body 6 at a certain time is A, where the circular rotating body 6 is in sliding contact with the inner arcuate wall surface 2c.
In position, the toy body 7 is rotated counterclockwise, and the circular rotating body 6
At position B, where the toy body 7 is in sliding contact with the outer arcuate wall surface 2f, the toy body 7 is rotated clockwise, and at position C, where there are no inner and outer arcuate walls, the rising surface 2h of the annular portion 2j is Therefore, the rotation of the rotating shaft 5 is stopped, and the lower end spherical surface or curved surface 5a is raised on the rising surface without biting, and on the descending surface 2i, the circular rotating body 6 rotates in sliding contact with the outer or inner arc-shaped wall surface. while being lowered.

In FIG. 2, the descending folded circular rotating body 6 is shown in sliding contact with the outer arcuate wall surface 2f.

Therefore, the outer and inner arc-shaped walls 2c and 2f are arranged as shown in FIG.
When the rotating shaft 5 and the circular rotating body 6 are arranged at equal intervals, the three toy objects 7 will each perform different movements.

The number and length of the arcuate wall surfaces and the number of toy bodies may be other than those mentioned above.

In Figures 2 and 3, an annular part with a continuous rising surface and a descending surface is formed in a band shape between the inner and outer arcuate walls, separated from both walls, but it fills in the space between the two walls. It may be formed in width. The height of the annular portion may be different from that of the other. Furthermore, if the wall spacing etc. are configured so that the operation is switched at angular intervals of 60 degrees, all operations can be made to be different. Furthermore, if a wall surface provided on the side of the descending surface is provided partially with respect to the descending surface, even more varied operations can be achieved.

Since the present invention is configured as described above, when the rotating shaft and the toy body are moved upward, the circular rotating body does not come into sliding contact with the wall surface, so it is not forced to rotate, and the drive source is not overloaded. Since it is not restrained by the wall surface, the toy body is free to ascend and rotate or stop, and since the circular rotating body is not in contact with the inner and outer arc-shaped walls at the same time, it does not place a heavy load on the drive source. Moreover, the circular rotating body is slidably contacted at the brim portion with the inner and outer arcuate wall surfaces, respectively, to ensure forward and reverse rotation and vertical movement. Furthermore, even if the contact between the wall surface and the circular rotating body increases, even if the lateral pressure resistance becomes large, it is absorbed by the eccentricity and torsion caused by the elasticity of the collar and the circular rotating body, so that no heavy load is applied to the drive source, and the movement of the toy body is vertical and normal. It is possible to provide a rotating toy with a music box that exhibits an excellent effect of arousing the interest of viewers through counter-rotating rotation and revolving movement of the entire toy in one direction.
