Description

本発明は、例えば測定面として壁面の垂直度を測定する水準器に関するものである。 The present invention relates to, for example, a spirit level that measures the verticality of a wall surface as a measuring surface.

壁面などの立面に当接する基準面が底面に設けられている直方体形状の器体内に、気泡管測定器を備えた取付体が装着されていると共に、この気泡管測定器が器体の側面に形成されている窓孔から視認し得るように構成されていて、立面に器体底面の基準面を当接させ、この立面に対して水平方向に横設された前記気泡管測定器の気泡位置を見ることで立面の垂直度を測定可能となる水準器が従来から実施されている。 An attachment body equipped with a bubble tube measuring device is mounted inside a rectangular body having a reference surface that contacts an elevation surface such as a wall surface on the bottom surface, and this bubble tube measuring device is attached to the side surface of the device. The bubble tube measuring instrument is configured so that it can be visually recognized from the window hole formed in the above surface, and the reference surface of the bottom surface of the instrument is brought into contact with the elevation surface, and the bubble tube measuring device is installed horizontally with respect to the elevation surface. A spirit level that can measure the verticality of an elevation by observing the position of air bubbles has been conventionally implemented.

このような垂直度測定用の水準器は、測定面（壁面などの立面）に対して正対した姿勢で測定者が器体を立面に当接させるが、気泡管測定器が器体の側面から視認可能な構成であるため、側方から器体（気泡管測定器）を覗き込まなければならない。即ち、立面に正対した姿勢のまま気泡管測定器による測定ができないため、作業能率が悪いと言える。 In such a level for measuring verticality, the measurer brings the instrument into contact with the elevation in a posture facing the measurement surface (elevation such as a wall surface), but the bubble tube measuring instrument is the instrument. Since the structure is visible from the side of, the body (bubble tube measuring device) must be looked into from the side. That is, it can be said that the work efficiency is poor because the measurement with the bubble tube measuring device cannot be performed while the posture is facing the elevation.

そこで、出願人は、ミラー部を利用して器体上面から見ても測定できるようにし、測定面となる立面に器体を当接させ、立面と正対した姿勢のままで、側方から覗き込むことなく、そのまま気泡管測定器を視認して測定することができる水準器を開発し、特許第３５０４５９１号（特許文献１）を取得している。 Therefore, the applicant makes it possible to measure from the upper surface of the body by using the mirror portion, brings the body into contact with the elevation to be the measurement surface, and keeps the posture facing the elevation on the side. We have developed a leveling device that can visually and visually measure the bubble tube measuring device without looking into it from the side, and have obtained Patent No. 3504591 (Patent Document 1).

一方、水準器は、夜間や暗所で使用されることも多いが、暗いと気泡管測定器が見づらいために、素早く正確に測定することが難しい。 On the other hand, the spirit level is often used at night or in a dark place, but it is difficult to measure quickly and accurately because it is difficult to see the bubble tube measuring device in the dark.

そこで、気泡管測定器を照らす光源を備えて、暗所での測定が容易な水準器も従来から提案されている（例えば、特許文献２参照）。 Therefore, a spirit level having a light source for illuminating the bubble tube measuring instrument and easy to measure in a dark place has been conventionally proposed (see, for example, Patent Document 2).

特許第３５０４５９１号公報Japanese Patent No. 3504591 特開２００２−４８５３８号公報Japanese Unexamined Patent Publication No. 2002-48538

出願人は、上記特許文献１のようなミラー視認機構が設けられている水準器にも、気泡管測定器を照らす光源を設けて暗所での測定が可能となるようにしたいと考えた。 The applicant wanted to provide a light source for illuminating the bubble tube measuring device in the spirit level provided with the mirror visual recognition mechanism as in Patent Document 1 so that the measurement can be performed in a dark place.

しかし、光源で気泡管測定器を照らすと、器体側面から視認することは問題ないが、器体上面から視認する場合に、光源の直射光がミラー部に反射して目に飛び込み、眩しくて気泡管測定器の反射像が非常に確認しづらくなってしまうという問題に直面した。 However, when the bubble tube measuring instrument is illuminated with a light source, there is no problem in visually recognizing it from the side surface of the instrument. I faced the problem that the reflected image of the bubble tube measuring instrument became very difficult to confirm.

出願人は、このような問題に直面後も試行錯誤した末に、光源の照明光により暗所でも素早く且つ正確に測定を行うことができ、ミラー視認機構を介した器体の上面から視認される気泡管測定器の反射像も適度な照明により容易に視認可能となる本発明の水準器を完成させるに至った。 Even after facing such a problem, the applicant can perform quick and accurate measurement even in a dark place by the illumination light of the light source after trial and error, and is visually recognized from the upper surface of the object through the mirror visual recognition mechanism. We have completed the spirit level of the present invention so that the reflected image of the bubble tube measuring instrument can be easily visually recognized by appropriate illumination.

好適と考える本発明の実施形態を、図面に基づいて本発明の作用を示して簡単に説明する。 An embodiment of the present invention that is considered to be suitable will be briefly described by showing the operation of the present invention based on the drawings.

測定面Ａとしての壁面などの立面Ａに器体２底面の基準面１を当接すると、気泡管測定器４が水平方向に配設されるので、この気泡管測定器４の気泡５位置により立面Ａの垂直度を測定できる。 When the reference surface 1 on the bottom surface of the body 2 is brought into contact with the elevation surface A such as a wall surface as the measurement surface A, the bubble tube measuring device 4 is arranged in the horizontal direction. Can measure the verticality of the elevation A.

この際、気泡管測定器４は、器体２の側面３から視認できるが、器体２の上面６からも反射視認できる。 At this time, the bubble tube measuring device 4 can be visually recognized from the side surface 3 of the body 2, but can also be visually recognized by reflection from the upper surface 6 of the body 2.

具体的には、ミラー視認機構８のミラー部７に映る気泡管測定器４の反射像Ｉを、前記基準面１の反対側に存する器体２の上面６から視認できる。 Specifically, the reflected image I of the bubble tube measuring device 4 reflected on the mirror portion 7 of the mirror viewing mechanism 8 can be visually recognized from the upper surface 6 of the body 2 existing on the opposite side of the reference surface 1.

即ち、基準面１を立面Ａに当接させた際、器体２の側面３から気泡管測定器４を覗き込むことで垂直度の測定を行うことができるが、わざわざ側面３を覗き込まなくても、立面Ａと正対した姿勢のまま、器体２の上面６からミラー視認機構８のミラー部７を介して気泡管測定器４（の反射像Ｉ）が反射視認でき、立面Ａの垂直度を容易に測定できる。 That is, when the reference surface 1 is brought into contact with the elevation A, the verticality can be measured by looking into the bubble tube measuring device 4 from the side surface 3 of the body 2, but the side surface 3 is purposely looked into. Even without it, the bubble tube measuring device 4 (reflection image I) can be reflected and visually recognized from the upper surface 6 of the body 2 through the mirror portion 7 of the mirror viewing mechanism 8 while maintaining the posture facing the elevation A. The verticality of the surface A can be easily measured.

また、本発明は、例えば夜間などの暗所下においても、器体２に設けられている光源９から照射される照明光によって気泡管測定器４を視認することができるので、暗い場所でも器体２の側面からあるいは器体２の上面６から光源９によって照らされた気泡管測定器４を視認して測定が可能である。 Further, according to the present invention, the bubble tube measuring device 4 can be visually recognized by the illumination light emitted from the light source 9 provided in the body 2 even in a dark place such as at night, so that the device can be visually recognized even in a dark place. The bubble tube measuring device 4 illuminated by the light source 9 can be visually observed from the side surface of the body 2 or from the upper surface 6 of the body 2.

この際、光源９から気泡管測定器４を通過して前記ミラー部７に向かう照明光は、気泡管測定器４と光源９との間に配設された減光部10により減光若しくは遮断されるので、たとえ前方への指向性が強いＬＥＤが光源９として採用されていたとしても、光源９の眩しい直射光がミラー部７で反射して視認されることはなく、減光部10を介して直接若しくは間接照射された眩しさのない気泡管測定器４の反射像Ｉを視認可能である。 At this time, the illumination light passing from the light source 9 through the bubble tube measuring device 4 and heading toward the mirror portion 7 is dimmed or blocked by the dimming unit 10 arranged between the bubble tube measuring device 4 and the light source 9. Therefore, even if an LED having a strong forward directivity is adopted as the light source 9, the dazzling direct light of the light source 9 is not reflected by the mirror unit 7 and is not visually recognized, and the dimming unit 10 is used. The reflected image I of the bubble tube measuring device 4 without glare, which is directly or indirectly irradiated through the light source, can be visually recognized.

A hollow bubble tube accommodating portion 19 is provided in the radial direction of the inside, and the bubble tube 17 for measurement is accommodated in the bubble tube accommodating portion 19 and closed by a lid plate 18 to support the bubble tube.
