Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display tool mainly used for displaying terrain, and in particular, the display tool is a sphere, and the sphere forming the display portion is rotated on a support board in all directions. Regarding those that are movably supported.

[0002]

2. Description of the Related Art Generally, the mainstream of display devices is composed of members having a flat surface such as paper and plates. Therefore, when there is a large amount of information displayed on it, one side is not enough and the back side is used, but it is troublesome to turn over the display tool and know the information displayed there whenever necessary. there were.

Therefore, in the case of a relatively large display device such as a map, the front and back of the display device can be seen quickly.
Alternatively, the sphere meaning, for example, the globe, is used for various reasons, such as to match the accurate counting of celestial bodies such as the spherical earth and attachment. As is well known, the world globe rotatably supports a sphere that depicts the terrain on the earth by means of a semicircular support frame at its earth axis.

[0004]

However, such a thing is convenient for recognizing or grasping the globe as an astronomical object, but if it is not used as a map,
The part you want to see does not always come in front of the face, and it may be difficult to use. Furthermore, even with the general display device described above, the display device needs to be displayed each time the information displayed on the back side is viewed. There was an inconvenience to turn over.

[0005]

In order to solve the above-mentioned inconvenience, the present invention comprises a display tool composed of a sphere and a support board for supporting the display tool, and the surface of the sphere is coated with a synthetic resin. In addition to the above, there is a spherical display tool in which the support board is provided with a support portion that rotatably supports the sphere by at least three support portions arranged on one plane. It consists of a sphere with a topographical map on its surface and a support board for supporting the sphere. The support board is a globe with at least three support parts arranged on one plane. .

[0006]

The display tool is a sphere, and a large amount of information can be displayed on its wide outer peripheral surface. In addition, the display is supported by three supporting parts on the support board, and when trying to view information, rotate the display to constantly view the information displayed there, for example, the required terrain from the front. You can The spherical display has a synthetic resin coating, and its surface can be filled with a water-based felt-tip pen.
In addition, since it can be easily erased, it is possible to write or erase necessary information above the already recorded information.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. In the figure, 10 is a spherical display according to the present invention,
Specifically, it is a globe. The display 10 is a sphere 20 made of hard synthetic resin, specifically polyester.
And an iron support board 30 that supports it.

A map is attached to the surface of the sphere 20,
Its outer surface is coated with transparent polyester. There are various methods of making the sphere 20, but for example, two hemispherical halves are superposed and joined at a circular opening, or formed by powder molding. Powder molding uses a mold with a spherical cavity, and heats the mold, and slowly inserts synthetic resin powder into its inner surface and slowly rotates it to melt the powder and deposit it on the inner surface of the mold. Is.

As shown in FIG. 1, the support board 30 is made by cutting a thick iron plate with a lathe, and has a substantially disk-shaped support member 3.
1 and a peripheral wall 32 that stands up in a ring shape from the peripheral edge thereof are integrally formed. The support board 30 is made heavy in this way in order to prevent the support board 30 itself from sliding on the desk or falling when rotating the sphere 20 supported on the support board 30. The surface of the support board 30 is coated with a Teflon (trademark of tetrafluoroethylene) film so that the spheres 20 placed thereon can slide well. On the other hand, a felt or other non-woven fabric 33 is thinly adhered to the lower surface of the support board 30 to prevent the support board 30 from slipping on the desk, and also to protect the desk surface from scratches. ing.

That is, the support member 31 is set to have a sufficiently large wall thickness. Further, the peripheral wall 32 is the sphere 2
It is provided to rotatably support 0, and in this embodiment, the plane shape is made circular, and the supporting portion for supporting the sphere 20 keeps the contact area to a minimum.
Surface processing is performed so as to form a smooth arc surface 34 that is convex outward.

The peripheral wall 32 for supporting the sphere 20 is not necessarily limited to this, and is, for example, shown in FIGS.
Alternatively, as shown in FIG. 7, it is possible to provide hemispherical recesses 34a at three positions on the upper surface of the support member 31 and to support the hemispheres by the three balls 35 supported by the recesses 34a. Both belong to the category of this invention. Also,
The plane formed by the three balls 35 is the support member 3
Although it may be arranged in parallel with the bottom surface of No. 1, it may be provided at an angle.

A vibrating means 40 for generating a slight vibration may be provided on the upper surface of the support member 31. Although not shown, the vibrating means 40 is provided with a small weight that can reciprocate, is urged by a spring toward one side, and is attracted by a solenoid from the other side. Four
Reference numeral 1 is an electric cord for connecting the solenoid to indoor wiring. Further, the vibrating means 4 is provided on the upper surface of the support member 31.
It is also possible to send pressurized air instead of 0 and thereby make the sphere 20 lightly float above the upper surface of the peripheral wall 32.
That is, it is possible to open a vent hole (not shown) that communicates with the pressure source.

Therefore, when the spherical display device 10 according to the present invention is used, it is first placed on a desk and the support member 3 is used.
The sphere 20 is placed on one or three spheres 35. In this state, a hand is put on the sphere 20, and the sphere 20 is rotated so that the desired portion comes to the front. When the vibrating means 40 is used, if the plug of the electric cord 41 is plugged into the outlet, the vibrating means 40 immediately operates and the peripheral wall 32 of the support board 30 vibrates, so that the sphere 20 placed on the vibrating means 40 also. The sphere 20 is vibrated and temporarily lifted from the peripheral wall 32, so that the sphere 20 can be rotated more easily. Further, if the exciting force is strengthened, the sphere 20 is lifted up by a minute amount and is loosely rotated by itself, which may increase the decorativeness on the desk.

Although the above-mentioned embodiment shows an example in which the present invention is applied to a globe, the present invention is not limited to this, and it can be diverted to another celestial body, for example, a lunar globe representing the surface of the moon. . Further, the use of the spherical display device 10 is not limited to the display of the terrain, and it is used as a chart or a chart, such as an interest rate chart, a fee chart, or a fare chart, which has a relatively large number of parameters. And convenient.

[0015]

As described above, according to the present invention, since the spherical body 20 forming the display portion is supported by the support board 30 so as to be rotatable in all directions, the information displayed on the spherical body 20 is displayed. Can be moved to the front of the user with a simple operation, and there is an effect that information can be easily read. Further, since it is supported on the support board 30 in a relatively small area for supporting the sphere 20, there is an effect that the above operation can be performed lightly. Further, if the supporting plate 30 is provided with a vibrating means, the frictional resistance between the spherical body 20 and the supporting plate 30 is reduced, so that the turning operation can be performed lightly, and the exciting force of the spherical body 20 is increased. If the strength is set so as to rotate, the display effect of the spherical display device 10 can be made more remarkable.
