JP3008494U - Altitude difference measuring level - Google Patents

Abstract

(57) [Summary] [Purpose] The purpose of the invention is to provide an inexpensive small-sized tool that can easily measure the height difference between two spatially separated points. [Structure] A transparent water bubble floating level (1) is integrally formed with an optical reflection surface (2) inclined at 45 degrees with respect to the level surface as a prism.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a spirit level.

[0002]

[Prior art]

 In the past, spatially distant level measuring devices have been large or expensive.

[0003]

[Problems to be solved by the device]

 It was made to provide a low-priced small tool that can easily measure the height difference between two spatially separated points.

[0004]

[Means for Solving the Problems]

 A reflecting surface (2) is attached to a level (1) in which a liquid and air bubbles are sealed in a space in which the central part of the upper part of the inner surface is higher than the surroundings and which is tilted at 45 degrees with respect to the level.

[0005]

[Action]

 If you look through this altitude difference measuring level from directly above and set the level centered on the water bubble, and at the same time look at the horizontal side reflected in the center of the reflective surface (2) below it, you will see the altitude difference measurement. It can be seen that it is at the same height as the spirit level.

[0006]

【Example】

 An example of the present invention will be described below. A spirit level (1) that seals liquid and air bubbles in a space where the center of the upper part of the inner surface is higher than the surroundings, and a reflecting surface (2) that is inclined 45 degrees to the level surface are integrally molded as a prism, and the lower part is If you put this level for altitude difference measurement, which constitutes a plane parallel to the level plane, on the measurement surface, you can use it as a level to know the level of that level, hold it in your hand and look from directly above it to see for water bubbles. When the level is aligned with the center and the two marks are overlapped and looking at the horizontal side reflected on the reflective surface (2) underneath, the mark can be seen at the same height as the altitude difference measuring level. I understand. The reflecting surface (2) can be used as a half mirror, and the electronic level (1) can be placed below the reflecting surface (2). As shown in FIG. 2, the upper surface of the prism is shaped like a lens, the lens is placed, the reflecting surface (2) is curved like a lens, or the surface of the prism facing in the horizontal direction is shaped like a lens. Alternatively, the accuracy of measurement can be increased by enlarging the scenery by, for example, placing the lens so that the lens can be moved so that the focus can be adjusted.

[0007]

[Effect of device]

 Since the present invention has the above-mentioned configuration, it has the following effects. Although it is a low-priced level made of transparent resin that fits in the palm of your hand, you can easily measure the difference in altitude between two distant points.
