Abstract

PROBLEM TO BE SOLVED: To provide a spirit level capable of horizontal measurement of a plurality of measurable faces solely by itself.SOLUTION: In a spirit level, sides of rectangular ring-shaped grooves 3A, 3B, 3C and 3D each having a central part curved outward are formed in a transparent base 1, each side of the grooves 3A, 3B, 3C and 3D in the base 1 is caused to form a hollow by integrating respective faces forming the respective sides of the grooves 3A, 3B, 3C and 3D and a back plate 2 of an opaque material by adhesion, and liquid and bubbles are sealed into this hollow. The grooves 3A, 3B, 3C and 3D are so configured as to make inner side side-walls of their sides orthogonal to a rear face of the base 1, while sectional shapes of outer side side-walls of the grooves are configured to be arcs each centering on an open end of the inner side side-wall and to intersect with the inner side side-wall at a bottom.

Description

本発明は、水準器に関するものである。   The present invention relates to a spirit level.

従来の水準器は取付けられた水平測定対象となる面の水平を測定できるだけなので、測定対象物が動作モードに応じて回転し、水平測定対象面が複数となるような場合、それぞれの対象面に別々の水準器を取付けて使用する必要があった。   Since the conventional level can only measure the level of the horizontal measurement target surface, if the measurement object rotates according to the operation mode and there are multiple horizontal measurement target surfaces, It was necessary to install and use a separate level.

本発明は、単体で複数の測定対象面の水平が測定できる水準器を提供することを目的とする。   An object of this invention is to provide the level which can measure the horizontal of several measurement object surface alone.

上記課題を解決するため本発明は次のような構成を採用した。
請求項1の発明では、矩形リング状をなし、各辺の中央部は外側に湾曲した溝を有する透明な基体と、基体の溝の開口部側の面に接着された不透明な背板とを備え、溝と背板により形成される矩形リング状の空洞部に液体と気泡を封入した。 In order to solve the above problems, the present invention employs the following configuration.
In the invention of claim 1, a transparent base having a rectangular ring shape and having a groove curved outward at the center of each side, and an opaque back plate bonded to the opening side surface of the base groove are provided. A liquid and bubbles were enclosed in a rectangular ring-shaped cavity formed by a groove and a back plate.

請求項2の発明では、上記溝の外側の側壁の断面形状は円弧状に形成した。   In the invention of claim 2, the cross-sectional shape of the outer side wall of the groove is formed in an arc shape.

本発明によれば単体で複数の測定対象面の水平計測ができる。   According to the present invention, horizontal measurement of a plurality of measurement target surfaces can be performed alone.

請求項2の発明によれば、計測するとき表示用気泡の移動が速やかで、気泡の視認性が良い。   According to the invention of claim 2, when the measurement is performed, the movement of the display bubbles is quick and the visibility of the bubbles is good.

以下、本発明の水準器について図１を用いて具体的に説明する。
１は水準器の基体で、透明性を有しているポリカーボネイト樹脂、ポリアミド樹脂、アクリル樹脂などで構成される。
２は背板で、不透明な樹脂で構成される。
３は基体１に形成された矩形リング状の溝で、各辺３Ａ、３Ｂ、３Ｃ、３Ｄから成る。
４は溝の一辺である３Ａから基体１の側面上部までに貫通している液体、気泡注入孔である。
5は溝３の形成後残った島状部である。
６Ａ、６Ｂ、６Ｃ、６Ｄは目印で、水平計測時において気泡位置を明確に指示するため、溝の各辺３Ａ、３Ｂ、３Ｃ、３Ｄの中央部に一定の間隔を置き二箇所の線を入れ、この線は、開口部の端部から細い溝を切り不透明な樹脂をこの溝に充填して形成したものである。 Hereinafter, the level of the present invention will be specifically described with reference to FIG.
Reference numeral 1 denotes a base of a level, which is composed of a polycarbonate resin, a polyamide resin, an acrylic resin, etc. having transparency.
A back plate 2 is made of an opaque resin.
Reference numeral 3 denotes a rectangular ring-shaped groove formed in the base 1, and is composed of the sides 3A, 3B, 3C, and 3D.
Reference numeral 4 denotes a liquid or bubble injection hole penetrating from 3A, which is one side of the groove, to the upper portion of the side surface of the substrate 1.
Reference numeral 5 denotes an island-shaped portion remaining after the groove 3 is formed.
6A, 6B, 6C, and 6D are marks, and in order to clearly indicate the position of the bubble during horizontal measurement, put two lines with a certain distance in the center of each side 3A, 3B, 3C, and 3D of the groove. This line is formed by cutting a thin groove from the end of the opening and filling the groove with an opaque resin.

図２は本発明の完成図である。図１から図２までの組立経緯を説明する。
図１の基体１と背板２を接着で一体とした後、空洞部となった部分に、図２に示す液体、気泡注入口４から液体７と一つの気泡８を入れる。その後、液体、気泡注入口４を密閉することで完成する。
液体は無色透明なものが望ましいが、デザイン上の好みに応じて、有色透明のものや、有色不透明のものを使用することもできる。 FIG. 2 is a completed view of the present invention. The assembly process from FIGS. 1 to 2 will be described.
After the base body 1 and the back plate 2 of FIG. 1 are integrated by bonding, the liquid 7 and one bubble 8 are put through the liquid and bubble inlet 4 shown in FIG. Thereafter, the liquid and bubble inlet 4 is sealed.
The liquid is preferably colorless and transparent, but can be colored and transparent or colored and opaque, depending on the design preference.

図３は本発明の水準器の正面図である。
図３では、気泡８が辺３Ａの上辺にあり目印６Ａの中に納まった状態を示している。この状態が測定対象物が正確に水平であることを示している。 FIG. 3 is a front view of the level of the present invention.
FIG. 3 shows a state where the bubble 8 is on the upper side of the side 3A and is contained in the mark 6A. This state indicates that the measurement object is accurately horizontal.

図４は図３のイ−ロ断面図である。
本発明の水準器は図のように立てた状態で使用する。
図の３Ａは溝で、外側の側壁の断面形状が円弧状に形成していることを示している。この形状により水準器の測定対象面が変更されても、液体７の中を移動する気泡８は速やかに移動できる。また、図では最上部の位置に気泡が円弧状の側壁前部に出現することで視認性を高めている。 FIG. 4 is a cross-sectional view of FIG.
The level of the present invention is used in a standing state as shown in the figure.
3A in the figure is a groove and shows that the cross-sectional shape of the outer side wall is formed in an arc shape. Even if the measurement target surface of the level is changed by this shape, the bubbles 8 moving in the liquid 7 can move quickly. Also, in the figure, the visibility is enhanced by bubbles appearing at the uppermost position on the front part of the arcuate side wall.

図５、図６は、本発明の水準器の使用状態を示す斜視図で、一例としてカメラ台にカメラをセットしている状態を示す。これを具体的に説明する。
９は雲台のカメラ台である。１０はカメラ固定留め具、１１は支持板である。12はカメラである。
図５は、カメラを水平にセットしている状態である。図では本発明の水準器は、辺３Ａが上辺に来ているので、気泡８も辺３Ａ上辺面に現れている。この時、気泡が目印６Ａの中に納まれば、カメラ台は水平である。
図６は、図５の辺３Ａの水平状態からカメラ台を反時計回りに９０度回転し、辺3Ｂが上辺に来たところで、辺３Ｂの水平計測を行っている状態である。
この時、辺３Ｂが上辺に来ると、液体の中の気泡は常に上辺に出現するという自然現象を利用しているため、気泡は辺３Ａから移動し辺３Ｂに現れる。
この気泡が目印６Ｂの中に納まっていれば辺３Ｂは水平と確認できる。
辺３Ａと辺３Ｂが直交する関係にあれば、３Ｂが水平であれば必然的に辺３Ａは垂直と確認できるからカメラ台も垂直と成る。即ち、カメラを垂直にセットできる。 5 and 6 are perspective views showing the usage state of the level of the present invention, and show a state where the camera is set on the camera base as an example. This will be specifically described.
Reference numeral 9 denotes a camera platform for the pan head. Reference numeral 10 denotes a camera fixing fastener, and 11 denotes a support plate. 12 is a camera.
FIG. 5 shows a state where the camera is set horizontally. In the figure, since the level 3 of the present invention has the side 3A on the upper side, the bubble 8 also appears on the upper side of the side 3A. At this time, if the bubble is accommodated in the mark 6A, the camera base is horizontal.
FIG. 6 shows a state where the camera 3 is rotated 90 degrees counterclockwise from the horizontal state of the side 3A of FIG. 5 and the horizontal measurement of the side 3B is performed when the side 3B comes to the upper side.
At this time, when the side 3B comes to the upper side, the bubbles move from the side 3A and appear on the side 3B because the bubble in the liquid always appears on the upper side.
If this bubble is accommodated in the mark 6B, the side 3B can be confirmed to be horizontal.
If the side 3A and the side 3B are orthogonal to each other, if the side 3B is horizontal, the side 3A can inevitably be confirmed to be vertical, so the camera stand is also vertical. That is, the camera can be set vertically.

水準器を用いて水平計測を必要とするあらゆる産業に利用できる。   It can be used in any industry that requires level measurement using a spirit level.
