Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a globe, and more specifically to an omnidirectional globe that can be used by setting it at a desired position without setting the North Pole above.

[0002]

[Problems to be solved by conventional techniques and devices]

 Conventionally, a globe that is constructed by rotatably arranging the globe body with the world map displayed on the surface via a shaft member and a sash, unlike the map displayed in two dimensions, Since it is possible to understand at a glance the positional relationship between cities, it is widely used not only for learning but also for general purposes.

By the way, in the conventional globe configured as described above, in order to maintain the inclination of the earth axis with respect to the normal line of the orbital plane of the earth, the globe body is tilted 23.5 degrees with the north pole facing up. Therefore, not only is it difficult to see because the area around the South Pole is occluded by a part of the globe body, it is necessary to view the line of sight in line with the body of the globe. It was pointed out that there are issues to be solved in various respects, such as giving incorrect recognition that "is always above".

[0004]

[Means for Solving the Problems]

 Therefore, in this invention, a globe body having a world map displayed on the surface and a base portion for supporting the globe body are formed, and an arcuate concave portion formed to be slightly larger than the curvature of the globe body is formed on the base portion. In addition, by arranging small-diameter ball casters at multiple points on the inner surface of the arc-shaped recess to hold the globe body rotatably, it is possible to easily see not only near the South Pole but also anywhere on the globe body. It is something that can be done.

In this case, a magnet or a magnetized body is arranged at a predetermined position of the globe body, and a magnetized body or a magnet is arranged at a predetermined place on the inner surface of the arc-shaped recess of the base part, and the earth axis of the globe body is measured by the method of the orbital plane. If it is configured so that it is held at a predetermined angle with respect to the line, it can not only hold the North Pole upward when it is not in use, as in the conventional earth sense, but also, for example, if desired, It is convenient because the southern hemisphere including the South Pole can be held upward.

[0006]

[Work]

 In the omnidirectional globe according to the present invention, by rotating the globe body mounted in the arcuate recess of the base part in an appropriate direction, the desired position on the earth, the country, etc. can be easily visually recognized. Is.

【Example】

 A preferred embodiment of the omnidirectional globe according to the present invention will be described in detail below with reference to the accompanying drawings. The present invention is not limited to this embodiment, and it is needless to say that various modifications such as diversion to a celestial sphere can be made without departing from the spirit of the present invention.

In the attached drawings, an omnidirectional globe 10 according to the present invention is formed by attaching a piece of paper showing a world map to a sphere of a predetermined diameter and protecting the map surface with a transparent surface protective agent. Basically, the globe body 12 and a base portion 14 that holds the globe body 12 in a rotating state are basically configured.

At the center of the upper surface of the base portion 14, an arc-shaped concave portion 16 having a curvature slightly larger than that of the globe body 12 and set to an appropriate depth is provided, and the inner surface of the arc-shaped concave portion 16 is made of synthetic resin or the like. A plurality of small-diameter ball casters 18 as a material are arranged. By exposing a part of each ball caster 18 to the arc-shaped wall surface of the arc-shaped recess 16 and embedding it, the globe body 12 can be supported at a plurality of points and can be smoothly and freely rotated in a desired direction. To configure.

Further, for example, a magnet 20 is arranged inside the positions corresponding to the north pole 12a and the south pole 12b of the globe body 12, while the predetermined position of the inner surface of the arc-shaped recess 16 in the base 14 is set. That is, the magnetized body 22 such as an iron piece is arranged at a position offset by 23.5 degrees with respect to a vertical line passing through the center of the arc, and when not in use, the earth axis of the globe body 12 is 23. It is structured so that it can be naturally held in a state of being tilted 5 degrees (see Fig. 2).

As a means for holding the globe body in the same manner as the conventional earth sense when not in use, other than this embodiment, for example, a protrusion or a concave groove is provided at a predetermined position of the globe body 12. By providing either a groove or a protrusion at a predetermined position on the inner surface of the arc-shaped recess 16 of the base portion 14 and fitting these protrusions and the groove into each other, the earth axis of the globe body 12 is set to be inclined by 23.5 degrees. It goes without saying that appropriate means such as the above can be adopted.

When using the omnidirectional globe 10 according to the present invention having the above-described structure, the globe body 12 held in the arcuate recess 16 of the base 14 is rotated in an appropriate direction to obtain a desired shape on the map. It can be easily viewed by moving it to a position where it is easy to see the location or country. Further, when the globe is not used, if the magnet 20 on the back side of the south pole 12b of the globe body 12 and the magnetized body 22 of the stand portion 14 are opposed to each other, the globe body 12 can be held in the same state as the conventional globe, which is convenient. It will be. In this case, it is preferable that the magnetic flux density of the magnet 20 is set to be relatively strong so that the globe body 12 can automatically rotate and always maintain the same state as the conventional globe.

Furthermore, if a place name on the map of the globe body 12 is separately formed as a sticker 24 and the user can attach or remove it in a desired direction as needed, an education is possible. It can be expected to have a sufficient effect (see Fig. 3).

[0014]

[Effect of device]

 As described above, according to the omnidirectional globe according to the present invention, since the globe body can be rotated in all directions according to the position of the line of sight, it is easy and convenient to place it on any map. You can search for it and see it. In addition, it is possible to eliminate erroneous recognition that the north is always upward when viewed from the outer space as a whole, so it is possible to improve the educational effect. Furthermore, since there are no moving parts among the constituent members, the structure is simple, so it is inexpensive. It has various advantages such as that it can be manufactured, and its practical effect is extremely large.
