Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an origami panorama chart sheet on which information necessary for navigation, such as the depth of the sea, the direction of a tidal current, and the location of a lighthouse, is marked.

[0002]

2. Description of the Related Art Conventional nautical charts are obtained by marking the location of a lighthouse or a river, the depth of the sea, the direction of a tidal current, and the like on a single rectangular sheet body.

[0003]

The conventional marine charts are a single sheet of newspaper or a book having a large number of rectangular sections along the coastline. In the latter, the connection point with a different page was not clearly understood. The present invention seeks to make charts easy to handle and easy to see.

[0004]

A description will be given with reference to the drawings. In the origami type panoramic chart sheet according to the present invention, a main chart 3a is marked on the front surface 3 of the sheet main body 2, and is continuous with the front main chart 3a on the back surface 4 exposed on the front side when a part is folded. This is the submarine chart 4a marked.

[0005]

Embodiments of the present invention will be described with reference to the drawings.
"A, B, C, D, E, F, G" indicate the position of the long side common to the front surface and the back surface, AA indicates the sheet range on the front surface side, and CC indicates the center of the rear surface side. Set the sheet range to BB, D
-D indicates the sheet area on the back surface on both short sides. Reference numeral 2 denotes a belt-shaped sheet main body, which can be folded or rolled into a roll. 3 is the surface of the seat body 2, 4
Is the back surface of the sheet body 2. A main chart 3a is marked on the surface 3 of the seat body. Reference numeral 5 denotes a fold line, and when a part of the sheet body 2 is folded along the fold line 5 by mountain fold or valley fold, a part of the back surface 4 is exposed so as to be seen from the front side. Reference numeral 4a denotes a sub-nautical chart marked on the back surface 4, and a nautical chart continuous with the main nautical chart 3a is displayed. Thus, the origami type panorama nautical chart sheet 1 is constituted.

[0006]

The aspect ratio of the seat body 2 is 3L: 12L. The Seto Inland Sea is marked on the surface 3 side in FIG. The upper and lower points of 3L from the left side are referred to as "Iho". 6L from left
The point above is "b". The upper and lower points of 9L from the left side are referred to as "c". The upper and lower points of 10.5 L from the left are referred to as "nits".

[0007] On the back side of FIG. 2, the northern part of Ehime is in the section DD from "hahe" from the left end, and the section C is from "hahe" to "iho".
−C is Higashi Seto Inland Sea, section B from “Iho” to the right end
-B is marked with the Hoyo Strait.

In FIG. 1, when the left side is folded back with "Roch" as the center, as shown in FIG. 3, the Toyoyo Strait from Hichinada is displayed.

In FIG. 1, when the right side is folded back with "Lohe" as the center, the western part of Ehime prefecture from Suo Nada is displayed as shown in FIG.

In FIG. 1, when the left side is folded around "Roch" and the right side is folded back around "Roch", as shown in FIG. 5, the chart between Yamaguchi, Ehime and Oita prefectures is obtained. Is displayed.

In FIG. 2, when the left side is folded forward with "Nito" as the center and the right side is folded later with "Iho" as the center, the Nishi Seto Inland Sea is displayed as shown in FIG.

Although the above embodiment has been described taking the Seto Inland Sea as an example, the present invention can be applied to all Japan and the whole world.

The size of the paper is not limited to the band shape shown in the figure, but can be freely selected such as row A No. 1, row B No. 2, and the like. Also, the folding method can be selected not only in a direction perpendicular or at 45 degrees to the long side in the drawing but also in a desired angle.

In the present invention, both sides can be effectively utilized by folding the chart sheet. The direction of the chart sheet can be indicated with an accuracy of 0 degree by the folding angle. The angle of contact and the angle of the fold open the future development. By weaving, it is possible to continuously express the coastline around Japan.

[0015]

When moving from the first chart sheet to another chart sheet in a state where the coastline in the traveling direction is bent, if the first chart sheet is folded and overlapped, the coastline in the traveling direction is continuous. It is extremely convenient to handle because it can be seen around the coastline of Japan.
