Description

  The present invention relates to a floating bell device capable of floating a bell body in the air.

Bells are known as doorbells, alarm bells, doorbells and the like.
For example, Patent Document 1 discloses an electromagnetic bell in which a striking ball is fixed to one end of a Schmok and the other end is connected to a yoke.
However, as shown in Patent Document 1, the conventional bell is fixed to a frame, a frame or the like, or the bell is connected to a handle or the like to be held by hand.
Therefore, the inventor of the present invention has arrived at the present invention as a result of examining a novel bell device which has not been found before.

Japanese Utility Model Application Publication 63-170900

  An object of the present invention is to provide a bell device in which a bell body floats in the air.

  The floating bell device according to the present invention includes a base portion on which a floating magnet is disposed, and a bell body supported by the base portion, and has a floating device that causes the base portion to float in the air by using a repulsive force of magnetic force. It is characterized by

  Here, the base portion on which the floating magnet is disposed refers to a magnet provided on the floating device of the floating magnet or a magnet provided on the base portion which floats in the air due to a repulsive force generated by the generated electromagnetic force.

In the present invention, the bell body may be supported by a support member erected from the base portion, and a striking device may be provided on the inside of the bell body to squeeze the bell.
As a result, since the bell body which has floated up by the repulsive force of the magnetic force can be squeezed from the inside of the bell body by this striking device, the bell body which is floating rises from the center of the magnetic force generated from the floatation device. It is possible to suppress the deviation in the direction.

In the present invention, it is further preferable to have receiving means capable of remotely controlling the striking device.
In this way, various communication means can be used to ring the bell body.

  In the floating bell device according to the present invention, since the bell body floats in the air, there is a mystery, and there is no conventional mounting frame or the like for suppressing the vibration of the ringing bell, so that the sound resonates well.

The structural example of the floating bell apparatus which concerns on this invention is shown. The structural example inside a floating apparatus is shown. The 2nd Example of a bell is shown. The 3rd Example of a bell is shown. The 4th Example of a bell is shown.

  Although the structural example of the floating bell apparatus which concerns on this invention is demonstrated hereafter based on a figure, as long as a bell main body is floated in the air by magnetic force, it is not limited to a present Example.

FIG. 1 is a side view showing a state in which the base portion 11 is floating in the air by repelling the magnetic force generated from the floating device.
A floating magnet 14 having a circular outer shape is embedded in the base portion.
An example of the structure of the floating device 20 is shown in FIG.
By having the donut shaped base magnet 21, the magnetic flux center of the floating magnet coincides with the magnetic flux center of the base magnet 21, and in the same pole state, the base portion 11 floats, and the magnetic force in the repulsion direction generated from the base magnet 21. And fly up to a balanced position with the weight of the rising bell.

If the magnetic flux center of the floating magnet 14 deviates from the magnetic flux center of the base magnet 21 in the left and right and in the front-rear direction, the reaction force balance of the same pole is broken, which may cause falling magnetic attachment.
Therefore, as shown in FIG. 2, it is preferable to provide the positioning element (coil) 23 concentrically inside the inner diameter of the base magnet 21.
Further, a levitation force element (coil) 22 for adjusting the levitation height may be provided at the center of the base magnet 21.

As shown in FIG. 1, a shaft-shaped support member 13 is provided upright from the base portion 11, and the bell main body 12 is supported by the upper end portion of the support member 13.
Inside the bell body 12 is disposed a striking device 15 in which the striker 15a is protruded and retracted by an actuator such as a solenoid.
In the first embodiment shown in FIG. 1, the outer shape of the bell body 12 is substantially spherical, and the striking device 15 is attached to the shaft-like support member 13.

A second embodiment is shown in FIG.
It is an example which made the external shape of the bell main body 12a substantially conical shape.
In order to stably hold the striking device 15, an auxiliary frame 13 a is provided around the rod-like support member 13.

FIG. 4 shows a third embodiment.
An example is shown in which the bell main body 12b is formed into an inverted bowl shape and the receiving device 16 for operating the striking device 15 by communication means from the outside is provided.
The present embodiment shows an example in which the striking device 15 and the receiving device 16 are provided on the base portion 11, the arched support member 13b is erected from the base portion 11, and the bell main body 12b is supported.

A fourth embodiment is shown in FIG.
In this example, the bell main body 12c has a tree-like different shape, and a spherical fulcrum 13d is formed on the upper end of the support member 13c.
This embodiment is an example in which the inner top portion 12d of the bell main body 12c is swingably supported with respect to the fulcrum portion 13d of the support member 13c.

The bell rotates slowly when the base portion and the bell body or the like (these are collectively referred to as a bell) rise by the repulsive magnetic force of the floating device.
Therefore, adjustment means may be provided to stop the rotation or to change the rotation speed, and the timing at which the bell rings may be adjusted according to the rotation position of the bell.
