Description

[Detailed Description of the Invention] The present invention relates to a toy vibration device that reciprocates a moving element along a filament.

2. Description of the Related Art A device is known in which a lightweight moving element is loosely fitted into an elastic linear body, and vibration is applied to the base of the linear body to cause the moving element to reciprocate vertically or horizontally.

Such devices can be used as moving tables, play machines,
It is an interesting toy, has a simple structure, and is widely used because the movement of the mover is interesting.

As a conventional device of this kind, for example, Japanese Patent Application Laid-Open No. 50-1258
No. 48 is known.

However, since this device uses an AC electromagnet as a means of applying vibrations to the striated body, firstly, the vibration of the striated body is an ultra-fine vibration, which causes a large change in the operation of the slider. The drawback was that it could not be done.

Second, since it uses an AC electromagnet, it requires an AC power source, and as a toy it is difficult to make a battery-powered toy that is easy to carry, can be carried anywhere, and is difficult to manufacture at a low cost.

The present invention was made to eliminate the above-mentioned drawbacks, and it is possible to reciprocate the slider along the linear body using mechanical vibration means without using electromagnetic vibration means. This toy is characterized by the fact that the principle of the filament vibration generating means is completely different from conventional ones.

Hereinafter, details of the present invention will be explained along with embodiments shown in the drawings.

1 to 3 show one embodiment of the present invention, and are shown as an example of an upright type.

This device is assembled based on a relatively heavy base 1, and the lower end of a tightly wound coil spring 2, which can normally be maintained in an extended state, is fixed to the center of the base 1. A filament holder 3 is fixed to the upper end of the spring 2.

The filament holder 3 consists of an upper disc 4 and a lower disc 5,
A lower disc 5 is fixed to the upper end of the coil spring 2, and the upper and lower discs 4, 5 are connected by a distance rod 6 to maintain a predetermined distance.

As shown in FIG. 2, a motor 7 is mounted on the lower disk 5.
is fixed, and a weight plate 9 is fixed to the tip of the rotating shaft 8 at an eccentric position.

On the upper disk 4, in the vicinity of its periphery, filamentary bodies 10 are planted at equal angular intervals on the same circumference, with their lower ends fixed.

The filament body 10 is made of synthetic resin such as acrylic or steel wire, and is elastic and can maintain a straight state under normal conditions.

A lightweight slider 11 made of, for example, styrene foam and having various shapes and colors is slidably fitted into the filament 10 .

It is desirable that the movable element 11 and the filament body 10 be loosely fitted.

Stoppers 12 are fixed near the upper and lower ends of the filamentary body 10.

Note that a power switch 13 and a motor 7 are mounted on the base 1.
A knob 14 for adjusting the current to is provided.

Next, the operation of this embodiment configured as above will be explained.

First, when the power switch 13 is turned on, the motor 7 is rotated and the eccentric weight 9 starts rotating at a predetermined speed.

When the eccentric weight 9 starts rotating, the filament holder 3 starts to vibrate according to the spring constant of the coil spring 2 due to its inertial force.

As a result, the striatum 10 is connected to the node 1 as shown by the chain line in FIG.
5 and an antinode 16 is produced.

However, this vibration is not a simple vibration, but involves rotational movement as shown in FIG.

This appears as the so-called misosuri movement. When the filamentary body 10 begins to rotate in this way, the mover 11, which was at the lowest end by contacting the lower spring I/flange 12, receives a reaction force from the stopper 12, and gradually rotates the filamentous body 10. Starting to rise,
It extends from the abdomen 16 to the node 15.

At node 15, a complex movement is exhibited due to the synergistic effects of centrifugal force, frictional force 9 and gravity between the filament body 10 and the moving element 11, and the moving element, on which a large downward force is applied, now descends. Start.

Further, the moving element that has passed the node 15 continues to rise further, and when it comes into contact with the upper stopper 12, it receives a reaction force from the stopper 12 and starts descending again.

As described above, each moving element repeatedly rises and falls depending on its size and force relationship, and performs a continuous movement, which is observed by the viewer as an extremely varied movement along with its color effects.

FIG. 4 shows another embodiment of the present invention. This embodiment is illustrated as a horizontal type, and the same parts as in FIGS. 1 to 3 are designated by the same reference numerals.

In this embodiment, the assembly is based on a rectangular board 17, and a vibrator 18 is disposed at one end of this board 17, and an elastic spring is installed inside the casing of this vibrator 18. A swing plate 20 is suspended via a rod 19, and a motor 7 is fixed onto the swing plate 20.

One end of the filament 10 is fixed to one side of the sliding plate 20, and the filament 10 is freely fitted into the upper surface of the casing of the vibrator 18.

On the other hand, a holding box 22 for the wire body 10 is fixed to the other end of the substrate 17, and a holding body 23 made of an extremely flexible material such as foamed polyurethane is accommodated in the holding box 22. The other end of the strip 10 is protruded.

According to the embodiment configured as described above, when the motor 7 is rotated and the eccentric weight 9 is rotated to apply vibration to the striatum 10, the striatum 10 vibrates with the above-mentioned nodes and antinodes. occurs, and the mover 11 repeats the same operation as described above.

In each of the above embodiments, when it is desired to change the operation of the slider, the current adjustment knob 14 is rotated to change the rotational speed of the eccentric weight 9, and the frequency of the striated body 10 is changed. If so, the period and amplitude will both change, making the movement of the mover even more complex.

As is clear from the above description, according to the present invention, unlike conventional excitation means using electromagnets, a large number of filamentary bodies are elastically supported by a holder supported by an elastic member such as a spring, Since it is configured to give vibration to the striated body by an eccentric weight rotated by a motor whose rotational speed can be freely adjusted, it imparts various movements to the slider that is loosely fitted to the striated body. It is possible to obtain movement of the moving element with an infinite number of combinations, and it can be made small and lightweight using batteries and motors at low cost. It is an excellent toy that can give excitement.
