JP3068919U - Map and rotation map set with magnet attached to magnetic north line - Google Patents

Abstract

(57) [Summary] [Problem] Create a static map, which rotates on its own toward north. The rotation and the stationary operation of this map are performed in a stable state even in rain and wind. SOLUTION: When a magnet is attached to the magnetic north line of the map and suspended in a case with a lid, the map rotates by the force of the magnet without being affected by rain and wind, and stops at the true north.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a map in which the map itself rotates in the direction of true north and is stationary.

[0002]

[Prior art]

 Conventionally, tasks such as confirming the route to be followed and the current location in mountain climbing, and identifying the name of a mountain that is visible in the distance, etc., are based on knowing magnetic north with a compass and correcting the west deviation angle of the magnetic compass direction determined for each map To turn the map to the right direction.

[0003]

[Issues to be solved by the invention]

 Many people forget that the north pointed by the magnet is not true north. If the azimuth correction of the magnetic compass direction is not performed, for example, at a west deviation of 6 degrees and 50 minutes, a straight 100 m northward shifts 11 m east from the correct point. Even if you remember, it is difficult and troublesome to correct accurately.

[0004] In rainy and windy weather conditions, it is very difficult to spread the map and use a compass.

Many people come to the mountains without a map and a compass because they are unfamiliar with handling and troublesome. Even if you bring it, there are many people who say that you leave it in Zach.

[0006]

[Means for Solving the Problems]

 Create a map linked to the function of the magnet's finger polarity. In other words, a magnet is attached to the magnetic north line of the map, and when it is hung with a thread, the map rotates and stops at the north. This is the correct orientation of the map at your current location.

[0007] The map is suspended in a case with a lid so that the rotation and the static operation of the map are not hindered even in the wind or rain.

[0008] In order to be able to see the map immediately at any time, the rotation map set is sized to be hung from the neck with a string or carried in a waist pouch.

[0009] In order to be able to replace and use the map in any area, the attachment and detachment of the map and the magnet should be repeatedly stopped.

[0010]

[Embodiment of the invention]

 An embodiment of the invention will be described with reference to the drawings. FIG.

1 is a map of FIG. A magnet (B) is attached to the magnetic north line (1) passing through the center point of the map (A) from the back side of the map (A). When the map thus formed is hung with a thread, it rotates and turns to the north and stops. next,

2. A rotation map set according to claim 2 will be described. FIG. 2 is a circular map, but notches (4, 5) for attaching a magnet (D) are provided at the north and south ends of the center hole (3) and the magnetic north line (2) passing therethrough. It is a map (C) characterized by the following. Fig. 3 is characterized by providing notches (4, 5) on the map (C), claws (6, 7), and a center hole (8) at both ends of the north and south poles. (D). FIG. 4 shows a thread (E) having a stopper (9) at the end for suspending the map with magnets. FIG. 5 shows a case (F) having a circular lid with a transparent top surface and having a center hole (10) and a hook (11) for fixing a hanging thread. The above components are combined as shown in FIG. 6 and suspended. When the map with a magnet is released, the string hanging on the stand is released and falls to the bottom of the case with lid (F) so that it does not shake. If the upper surface of the lid of the case with lid (F) is a convex lens, the map can be enlarged and viewed.

[0011]

[Effect of the invention]

 If the map to be rotated is a climbing map, anyone can easily check the map on the current location and the direction to go, which is useful for safe climbing.

[0012] If the map is a view direction chart, it becomes a personal view board, and the enjoyment of mountain climbing increases.

[0013] If the map is a topographic map such as 1 / 50,000, it is effective for countermeasures against a lost child accident when harvesting wild plants.

If the map is a map for tourist information, it is a simple navigator for visiting historic sites, shrines and temples, and the like.

In the case of a large theme park, for example, “Tokyo Disneyland”, if the guide map rotates and stands still, it becomes a moving guide board when moving in the park.
