Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to the structure of a three-point compass that allows you to check your current location on a map.

[0002]

[Prior art]

 Conventionally, the position was confirmed using magnets or the like, but it was not easy for a beginner to accurately confirm his / her current position on a map.

[0003] In particular, when getting lost in orienteering or hiking, it is almost impossible for a beginner who is not accustomed to handling magnets to plot his / her current position on a map and confirm it. There was a problem.

[0004]

[Problems to be solved by the invention]

 This invention was made to solve the problems described in the prior art, and aims to provide a three-point compass that allows even a novice to easily check his / her current location on a map. Is what you do.

[0005]

[Means for Solving the Problems]

 The three-point compass of this invention is characterized by stacking three long and narrow plates with slits in the length direction, connecting one end of these plates rotatably, and graduation on the top plate. Is what you do.

[0006]

[Embodiment of the invention]

 An example of an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, three elongated plates 2, 2 'provided with slits 1, 1', 1 "in the longitudinal direction are provided. As shown in FIG. 2, one end P, P ′, P ″ of the plates 2, 2 ′, 2 ″ is rotatably connected by, for example, an eyelet 4. Scale 3 is applied to plate 2.

The plates 2, 2 ′, and 2 ″ are strip-shaped thin plates made of a plastic plate, a metal plate, a wooden plate, or the like, and in this example, a case is shown in which the tip is formed into a sharpened shape. The invention is not limited to this, and may be formed into a rounded shape.

The scale 3 of the uppermost plate 2 is set according to the scale of the map 5, and when the length on the map 5 is measured by the scale 3, the actual scale can be read. Note that the scale 3 is unnecessary to confirm the current position on the map, and may be omitted as necessary.

The slits 1, 1 ′, 1 ″ have a function of seeing and positioning a target, and therefore, a linear mark having an equivalent function can be formed by slits 1, 1 ′, 1 ′. It may be applied instead of 1'1 ".

At the time of implementation, as shown in FIG. 4, for example, first, the board 2 is opened on the map 5, and the forest 6 described on the map 5 and the forest 6 ′ which is actually visible are directly connected. Adjust so that they are on the line.

Next, the board 2 ′ is opened, and the island 7 described on the map 5 and the actually visible island 7 ′ are aligned so as to be located on a straight line.

Next, the board 2 ″ is opened, and the factory 8 described on the map 5 and the factory 8 ′ that is actually visible are aligned so as to be located on a straight line. The intersection of '2' is your current position on the map 5.

[0013]

[Effect of the invention]

 Since the present invention is configured as described above, it has the following effects. You can check your current location accurately on the map. Since the handling is simple, even a beginner can easily operate. By measuring the length on the scaled map, it can be read in actual length. Since the structure is simple, mass production can be performed at low cost.
