Description

[Detailed explanation of the idea] This invention relates to a cover to protect the map.

This invention displays a scale scale and a direction scale on a map cover case or map cover that stores and protects the map, and makes it possible to easily measure or know the distance and direction from the map based on the scale scale and direction scale.

Conventionally, single-sheet maps are folded to a required size for ease of use and other reasons, and are stored in a map cover case and sold. In addition, bound atlases are sold with a cover placed over the cover to prevent defacement or other damage, just like general books.

Maps have their own scale and direction, which are always displayed on the map, and when using a map, you know the distance and direction according to these scale and direction. To measure distance, a device such as a divider is usually used, but since ordinary users often do not have these tools, they use their eyes or their fingers as a divider. However, both methods are inaccurate and inconvenient.

Also, in terms of direction, north is not always set directly above the map; on some maps it may be directly opposite, directly below, and in many cases the pinpoint position is located in the corner of the map. Since the position is far from the measurement position, visual measurements are extremely inaccurate.

This idea was made in view of the above points, and was designed to display a scale scale and an azimuth scale on the cover, which was originally used for the purpose of protecting the map, for ease of use.

This invention will be explained below with reference to drawings that are an example of implementation. 1 is a map cover case that individually stores a single map 2, and this is a case that stores the map 2 in a folded state as required. A paper board of a predetermined thickness is cut to the required size, a spine 3 is placed in the center,
It is provided in a rectangular shape that can be folded in two from the back folding lines 3a and 3b on both sides, with one side connected to the back folding line 3a serving as the case main body 1a, and the inner surface having folding pieces 4a and 4b connected to the side edges and the bottom edge. A pocket 4 is provided in an L shape, and the folded map 2 is placed in this pocket 4.
Store it by holding it. The other surface from the back fold line 3b is used as the lid portion 1b, and a reinforcing piece 5 that is continuous with the side edge is provided on the inner surface of the lid portion 1b.

On the outer surface of the map cover case 1, that is, on the outer surface of the main body portion 1a and the lid portion 1b, the scale scales 61 and 62 are arranged in correspondence with the side edges and the bottom edge, and the base 71a, Half-cut azimuth scales 71 and 72 are displayed, respectively, with 72a aligned parallel to each other.

Since this invention is constructed as described above, the map cover case is divided into two parts as shown in Figure 3.
Scale marks 61 and 62 of map 2 in the folded state.
and azimuth scales 71, 72 are used. That is, as shown in FIG. 4, the map 2 is unfolded, the folded map cover case 1 is placed on top of it, and the intervals on the map 2 are determined by scale marks 61 or 62 on the side edge or bottom edge of the map cover case 1. It is measured using one of the following methods. This scale scale 6
1 and 62 are created using the scale of the stored map 2, so the actual distance can be read immediately there without the need for conversion, unlike when measuring with a ruler. If the width of the side edges of the map cover case 1 is too long to measure at one time, it can be unfolded as shown in FIG. 1 to cover the widths of the bottom edges of the main body portion 1a and the lid portion 1b. If that is not enough, move the map cover case and add up the number of times it has been moved. Therefore, a map comes with a measuring ruler displayed at a scale unique to the map, and it is convenient to use it whenever necessary to accurately measure the distance between two points.

Next, when looking at the direction of a certain point, since the direction scales 71 and 72 are provided on the map cover case 1 as described above, for example, as shown in FIG. The center of the base 71a of the azimuth scale 71 is placed on the point 8, and then the map cover case 1 is moved to make the fold line 3a parallel to the azimuth display 9 on the map 2. In this way, point A8
The orientation at can be accurately seen by means of the orientation scale 71. In the description of the above embodiment, the display is half of the northeast-south direction, so if you want to view the north-west-south direction, you just need to flip the map cover case 1 over to the opposite side. Therefore, in the past, it was only possible to see the general direction because it depended on the visual register, but with this invention, one edge of the map cover is used as the eye stability standard, so the corner of the map can be seen. Easy to find even if you are far away from the displayed direction display,
It can be precisely aligned and measured precisely, and since the azimuth scale is half-cut and its base parallel to the edge, it can be printed on an opaque material and displayed in the same way as a compass displayed on a transparent material. It can be used.

Furthermore, in the embodiment described above, half of the half-cut azimuth scales 71 and 72 are displayed on the front and back sides with the spine 3 at the center, but they may be displayed corresponding to other edges.

Although not shown as an example, this invention is not limited to map cover cases.
This method can also be applied to a thin cover that can simply be placed on the front and back of an atlas.

As described above, this invented cover adds new functions to the conventional map cover and brings great benefits to the use of maps.

Claims (1)

[Scope of utility model registration request] In a rectangular bifold map cover that stores a map inside, the scale scale of the map is displayed on at least one corresponding edge of the front and back outer surfaces of the cover, and the interval between two arbitrary points is displayed on the map taken out from the cover. In addition to making it possible to immediately estimate the actual distance, a half-cut azimuth scale corresponding to the front and back outer surfaces is displayed, with corresponding edges of the remaining portions as the respective bases, and the base center of the half-cut azimuth scale is marked on the map. A map cover that makes it possible to measure the orientation of a point on a azimuth scale by placing the edge of the map cover on the measurement location by aligning the edge with the orientation on the map and turning half of it from the left and right.
