Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic levitation device for an object, which can levitate an object in the air by using the repulsive force of magnetic force.

The object can be levitated by disposing a magnet on the object and generating a magnetic force in a repulsive direction against the magnetic pole on the object side from below.
For example, Patent Document 1 discloses "A MAGNETIC LEVITATOR" that levitates the second portion 104 with respect to the first portion 102 by magnetic force. It is difficult to match the center axis of magnetic force with that of the base part side, and if there is even a slight deviation between the center axes of magnetic force, the object may fall outside without being able to be levitated.
Therefore, in Patent Document 1, a slide hole is provided in the center of an object to be levitated, and a vertical rod 114 is arranged along this slide hole so that the object can only move up and down along this rod. .
This poses a technical problem of impairing the feeling of floating in the air.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a magnetic levitation device for an object that is easy to levitate the object in the air and has a compact structure.

A magnetic levitation apparatus for an object according to the present invention comprises an object to be levitated by magnetic force, mounting means for mounting the object in a state in which the object is not levitated, and an upper and lower parts from below the mounting means. and magnetic force generating means whose movement is controlled in a direction.

Here, the object has a magnet with one of the north pole and the south pole on the bottom side.
The magnet is provided inside or on the bottom of the object.
On the other hand, the magnetic force generating means may be not only a magnet but also an electromagnet such as a coil as long as it can generate upward magnetic force repelling the magnetic pole on the object side.

In the present invention, when an object is placed on the placing means in advance and aligned with the center axis of the magnetic force of the object, the magnet generating means is slowly raised from the lower side. This object floats.
In this case, contrary to the above, a repulsive force may be applied to the object by gradually and slowly lowering the placing means on which the object is placed in advance.
Further, when the magnetic force generating means is an electromagnet, the mounting means and the magnetic force generating means may be brought closer to each other in the vertical direction while generating the magnetic force in advance. By generating a magnetic force in the repelling direction in a state where the objects are brought close to each other, the magnetic force central axis on the object side and the magnetic force central axis on the magnetic force generating means side can be matched, and then brought closer to levitate the object in the air.

In the present invention, the object is not limited as long as it can be levitated in the air.
For example, when an orin, which is one of the Buddhist altar fittings, is floated and struck lightly, there is nothing to block the vibration and the sound reverberates.
Alternatively, a bell may be used, and in this case, a striker that can be wirelessly and remotely controlled may be provided inside or outside the floating bell.
In addition, various dolls, various toys, lighting fixtures, advertising tools, and the like may be used.
In addition, these objects may be levitated directly by magnetic force, or may be levitated by placing them on a stand that is separately levitated.

In the present invention, since the object is to hold the object before it is levitated, the placing means preferably has an opening or recess for placing and holding the object.
Here, the opening means that the inner diameter of the opening is smaller than the outer diameter of the object, and the bottom side of the object is partially accommodated in the opening.
Further, the recess means a recess having a surrounding wall so that the bottom side of the object can be accommodated, or a recess for holding the object by arranging a plurality of protrusions or protrusions concentrically.
In any case, the structure is not limited as long as the center axis of the object in the vertical direction can be determined.

In the present invention, the mounting means is the upper case body, the magnetic force generating means is provided in the lower case body, and the upper case body and the lower case body are mutually controlled to move in the vertical direction. may have been
In this way, by relatively moving the lower case body up and down along the inside or outside of the upper case body, the center axis alignment of the upper case body and the lower case body is stabilized, It is easy to handle because it is integrated as an appearance.
Both cases may be moved relative to each other in the vertical direction either manually or automatically, but it is preferable that they can be positioned and held.

In the present invention, by providing an opening or a recess in the object mounting means, even if the object falls for some reason while the object is floating, it will fit in the opening or the recess.
In the present invention, if the upper case body further has a cushion part or a standing wall part for preventing the object from rolling down when it falls on the outer peripheral side of the placing means, the object can be prevented from rolling. can be prevented.

In the present invention, a means for controlling rotation or stopping of the object may be provided while the object is floating.
This is because, depending on the use and purpose of the object to be levitated, it is preferable to control the direction and speed of rotation while the object is levitated in the air, or to have stopping means so as to stop the object in the air.
Here, the rotating and stopping means may be physical means such as members or air, or may be electrical means using electromagnetic force.

In the present invention, the object is levitated from below by the magnetic force generating means in a state where the object is previously positioned on the placing means, so that the object can be easily levitated.
