Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a music box toy that has an action body fixed to the end of a piano wire and which makes an action movement of a rotating decorative body.

Conventionally, various music box toys that are operated by a music box have been proposed, but their operations are generally simple and many lack interest in entertaining viewers.

The purpose of this invention is to make the action body fixed to the end of the piano wire of the rotary decoration make a subtle action movement by moving the rotating decoration up and down and rotating it in a fixed direction in time with the sound of the music box. Our goal is to propose music box toys that arouse people's interest.

The features of the present invention include a music box, a cam plate with serrated teeth that is rotated by the music box, and a wire that is rotatably supported at one end, crosses and abuts the cam plate at the middle part, and the other end moves up and down in an arc shape. and a rotating decorative body that is supported vertically and rotatably and has a disk at its lower end and an action body at its upper end via a piano wire, and the other end of the wire material is located at a position offset from the center of the disk. This is because they were brought into contact with each other.

The present invention will be explained below with reference to illustrated embodiments. 1st
From the figure to figure 3, the music box toy has two base plates 1,
2 are held in parallel by a plurality of supports 10 to form a base plate 1.
Music box 3 is placed and fixed on top, and music box 3
A barrel 11 is fixed on the frame 3a of the drum 12, and a drum 12 is rotated by a music box drive source built in the barrel.
A pinion 15 is meshed and rotated with a gear 14 fixed to one end, and the pinion is fixed to one end of a pinion shaft 16 which is supported by a bearing plate 4 fixed to the frame 3a, and a cam plate 5 is fixed to the other end of the pinion shaft. Fixed.

One end 6a of the wire material 6 is attached to the protrusion 1a on the base plate 1.
is rotatably supported, the intermediate portion 6b crosses and abuts against the cam plate 5, and the other end 6c is curved in an arc shape.

A central shaft 17 is vertically and rotatably supported on the shaft portion 2a of the base plate 2. A disk 18 is fixed to the lower end of the central shaft 17, and a position off the center of the lower surface of the disk 18 is a wire member 6. A rotary decorative body 7 is mounted on the other end 6c and fixed to the upper end of the central shaft 17.

The cam plate 5 has long sawtooth teeth 5a as shown in FIG.
A plurality of sets of irregular tooth shapes of a plurality of short serration teeth 5b are formed.

The rotating decorative body 7 is composed of a piano wire 8 fixed to the central shaft 17 and an action body 9 shaped like a butterfly.

When the music box toy is configured as described above and the winding key 19 is screwed onto the Zenmai shaft (not shown) which protrudes downward from the frame 3a of the music box 3 and the Zenmai is wound up, the drum 12 is rotated and the music box is closed. 3 is sounded, the cam plate 5 is rotated counterclockwise via the gear 14 and pinion 15, and the intermediate portion 6b of the wire material 6 intersecting with the cam plate 5 is gently rotated on the slope of the sawtooth teeth 5a, 5b. It is pushed upwards and then falls by its own weight on a falling surface.

With this operation, the other arcuate end 6c of the wire material 6 is brought into contact with the disc 18 at a position away from the center of the disc 18.
The disk 18 is intermittently pushed upward and moved up and down, and the other end is moved up and down in an arc to apply tangential force to the disk, so the disk 18 obtains a rotational force in a fixed direction, and the rotating decoration The body 7 moves up and down and rotates due to its own weight.

Since the rotating decoration body 7 is composed of a piano wire 8 and an action body 9 imitating a butterfly, the elasticity of the piano wire 8 causes the action body 9 to move up and down more than the amount of vertical movement of the disc 18, and vibrate slightly. , the butterfly rotates in a fixed direction, like a butterfly flapping its wings and flying.

The shape of the cam plate described above can be arbitrarily selected, and various vibrations with different amplitudes and frequencies can be applied to the rotary decoration body, and the rotation speed can also be changed.

Further, the action body 9 may have other shapes such as a butterfly, a dragonfly, a bird, etc., and the number thereof may be arbitrarily configured.

Since the present invention is constructed as described above, the other end of the wire material is brought into contact with a position away from the center of the disk, and the tooth shape of the cam plate is formed with irregular sawtooth teeth, so that the rotating decorative body can be A mechanism that can provide various vibrations with different frequencies and rotation in a fixed direction can be easily and inexpensively created, various vibrations and rotational speeds can be easily changed by changing the tooth profile, the vibration noise is small, and rotation decoration is possible. Even if the body is forcibly rotated or rotated in the opposite direction by an external force, it is safe because it is configured to rotate using a friction mechanism, and the movement of the action body vibrates subtly, creating an interesting feature that arouses the interest of the viewer. It is possible to provide a music box toy that exhibits excellent practical effects such as significantly improved performance.
