【０００９】
前記本体２の表面側の互いに異なる面には、複数の発光素子３ａ〜３ｎからなるＸ方向発光体３と複数の発光素子４ａ〜４ｎからなるＹ方向発光体４とが設けられ、各発光体３，４によって発光表示体１０が構成され、Ｘ方向及びＹ方向の傾斜状態を各発光体３，４により表示できるように構成されている。なお、この場合、Ｘ方向とは、鉄骨部材１の一面の方向を示し、Ｙ方向はこのＸ方向とは直交する方向を示している。前記Ｘ方向発光体３及びＹ方向発光体４は、発光素子３ａ〜３ｎ、４ａ〜４ｎが各々ほぼＶ字形に配列され、各々右側傾斜及び左側傾斜状態を目視によって直ちに識別できるように構成されている。なお、この場合、発光素子３ａ，４ａのみが発光すると垂直状態、３ｂ〜３ｎ，４ｂ〜４ｎが発光した時には何れかに傾斜した状態を示している。なお、この本体２、着脱機構５及び発光表示体１０により垂直度表示装置３０を構成している。
【００１０】
前記本体２内には、Ｘ方向及びＹ方向の傾斜角を計測する２軸傾斜計８が設けられ、この２軸傾斜計８からの２軸の傾斜角の信号８ａは傾斜計アンプ９を経て発光しきい値選択回路１２に入力され、この発光しきい値選択回路１２には前述のＸ方向発光体３及びＹ方向発光体４が各々接続されている。なお、前述の傾斜計アンプ９及び発光しきい値選択回路１２には、バッテリー７からのＤＣ電源がＤＣ／ＤＣコンバータ１１を介して各々供給されている。
【００１１】
次に動作について述べる。まず、本体２の切欠部２Ａを鉄骨部材１の角部１ａに当接させて取手６を矢印の方向に沿って回転させると、着脱機構５の永久磁石２０の位置が変わり磁束２３が鉄骨部材１を通ることにより本体２が鉄骨部材１の角部１ａに磁力によって装着される。この状態で電源をオンすると、２軸傾斜計８から出力される２軸の傾斜角の信号８ａは傾斜計アンプ９で増幅され、発光しきい値選択回路１２で選択的に振り分けられ、その信号８ａのレベルに応じてＸ方向とＹ方向の各発光体３と４の何れかの発光素子３ａ〜３ｎと４ａ〜４ｎが発光する。
前述の発光素子３ａ又は４ａのみが発光した場合には鉄骨部材１が垂直状態であることを示し、他の発光素子３ｂ〜３ｎと４ｂ〜４ｎが発光した場合には、Ｘ方向とＹ方向が左右何れかに傾斜をしている状態を示し、Ｘ方向及びＹ方向における傾斜状態を発光式に表示することができる。なお、右方向又は左方向として直列状に配置された各発光素子３ａ〜３ｎ、４ａ〜４ｎの数は、Ｘ方向で５個、Ｙ方向で５個用いているが、この数を図示よりも多くしてより視認性を向上させることができる。また、図示の発光素子３ａ〜３ｎ及び４ａ〜４ｎを用いることなく、発光型の数字表示を用いることもできる。また、発光素子３ａ，４ａのみの発光色を他と変えることもできる。
【００１２】
次に、図５及び図６は、前述の着脱機構５の他の形態を示すものである。すなわち、図５及び図６において、着脱機構５に設けられたヨーク２１には永久磁石２０及び巻線２６が設けられ、この巻線２６にはスイッチ２５を介してバッテリー２４が接続されている。従って、スイッチ２５をオフとした状態では、永久磁石２０の磁束２３のみが鉄骨部材１に流れるため吸着オン状態となる。また、図６のようにスイッチ２５をオンとした状態では、巻線２６に電流が流れると共にヨーク２１には永久磁石２０の磁束２３を打消す方向に巻線２６の磁束２３ａが流れる（巻線２６の巻き方向がそのように指定されている）ため、永久磁石２０の磁束２３による吸着力はなくなり吸着オフ状態となる。また、図５及び図６の吸着力は次の数２の(2)式の通りである。
【００１３】
【数２】

【００１４】
【発明の効果】
本発明による垂直度表示装置の着脱方法は、以上のように構成されているため、次のような効果を得ることができる。
すなわち、永久磁石の回転方向のみで吸着オン、オフを選択することができ、極めて簡単に確実な着脱を行うことができる。また、永久磁石と巻線を用い、電源オフ時に吸着オンとし、電源オン時に吸着オフとしているため、吸着時に電源を消費することがなく、省電力形の着脱機構を得ることができる。

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of a method of attaching and detaching a verticality display device according to the present invention will be described in detail with reference to the drawings.
Those represented by the reference numeral 1 in FIG. 1 is a steel member provided in a vertical state on the base 1A, the corner portion 1a of the steel member 1 forms a substantially longitudinal L-overall shape by notch 2A body The main body 2 is provided with a pair of attachment / detachment mechanisms 5 incorporating the permanent magnets 20 shown in FIGS. Each of the attachment / detachment mechanisms 5 has a configuration in which the permanent magnet 20 is rotated as is well known by handles 6 rotatably provided at both ends of the main body 2. The rotation of the handle 6 changes the position of the permanent magnet 20, Adsorption or non-adsorption to the second steel frame member 1 is achieved. That is, as shown in FIGS. 3 and 4, a flat plate-shaped permanent magnet 20 having N poles and S poles at both ends is positioned in the gap 22 of the yoke 21, and in the state of FIG. After passing through the steel frame member 1, the suction is turned on. Further, in FIG. 4, the magnetic flux 23 does not pass through the steel frame member 1, so that the suction is turned off. The suction force at this time is as shown in the following equation (1).
[0008]
(Equation 1)

[0009]
On the different surfaces on the front side of the main body 2, an X-direction light emitter 3 including a plurality of light-emitting elements 3a to 3n and a Y-direction light emitter 4 including a plurality of light-emitting elements 4a to 4n are provided. The light emitting display 10 is constituted by the light emitting members 3 and 4, and the light emitting members 3 and 4 can display the tilted state in the X direction and the Y direction. Note that, in this case, the X direction indicates the direction of one surface of the steel frame member 1, and the Y direction indicates a direction orthogonal to the X direction. The X-direction luminous body 3 and the Y-direction light emitter 4, the light emitting element 3a to 3n, 4a to 4n are arranged each substantially V-shaped, is configured to be immediately identified by each eye to the right slope and the left inclined state I have. In this case, when only the light-emitting elements 3a and 4a emit light, a vertical state is shown, and when the light-emitting elements 3b to 3n and 4b to 4n emit light, an inclined state is shown. The main body 2, the attachment / detachment mechanism 5, and the light emitting display 10 constitute a verticality display device 30.
[0010]
A two-axis inclinometer 8 for measuring inclination angles in the X and Y directions is provided in the main body 2, and a signal 8 a of a two-axis inclination angle from the two-axis inclinometer 8 passes through an inclinometer amplifier 9. The light is inputted to the light emission threshold value selection circuit 12, and the X direction light emitter 3 and the Y direction light emitter 4 are connected to the light emission threshold value selection circuit 12, respectively. Note that DC power from the battery 7 is supplied to the inclinometer amplifier 9 and the emission threshold selection circuit 12 via the DC / DC converter 11.
[0011]
Next, the operation will be described. First, when the notch 2A of the main body 2 is brought into contact with the corner 1a of the steel frame member 1 and the handle 6 is rotated in the direction of the arrow, the position of the permanent magnet 20 of the attachment / detachment mechanism 5 changes, and the magnetic flux 23 changes. 1, the main body 2 is attached to the corner 1a of the steel frame member 1 by magnetic force. When the power is turned on in this state, the two-axis tilt angle signal 8a output from the two-axis inclinometer 8 is amplified by the inclinometer amplifier 9 and selectively distributed by the light emission threshold value selection circuit 12, and the signal is output. Any one of the light emitting elements 3a to 3n and 4a to 4n of the light emitting bodies 3 and 4 in the X direction and the Y direction emits light according to the level of 8a.
When only the light emitting element 3a or 4a emits light, it indicates that the steel frame member 1 is in the vertical state. When the other light emitting elements 3b to 3n and 4b to 4n emit light, the X direction and the Y direction are changed. This indicates a state of tilting to the left or right, and the tilting state in the X direction and the Y direction can be displayed in a light emitting manner. The number of the light emitting elements 3a to 3n and 4a to 4n arranged in series as the right direction or the left direction is five in the X direction and five in the Y direction. By increasing the number, visibility can be further improved. Further, a light emitting type numerical display can be used without using the illustrated light emitting elements 3a to 3n and 4a to 4n. Further, the emission color of only the light emitting elements 3a and 4a can be changed to other colors.
[0012]
Next, FIGS. 5 and 6 show another embodiment of the above-mentioned attaching / detaching mechanism 5. That is, in FIGS. 5 and 6, a permanent magnet 20 and a winding 26 are provided on a yoke 21 provided on the attaching / detaching mechanism 5, and a battery 24 is connected to the winding 26 via a switch 25. Therefore, in a state where the switch 25 is turned off, only the magnetic flux 23 of the permanent magnet 20 flows to the steel frame member 1 so that the attraction-on state is set. When the switch 25 is turned on as shown in FIG. 6, a current flows through the winding 26, and a magnetic flux 23a of the winding 26 flows through the yoke 21 in a direction to cancel the magnetic flux 23 of the permanent magnet 20 (winding). 26 is designated as such), the attraction force of the permanent magnet 20 due to the magnetic flux 23 disappears, and the attraction state is turned off. 5 and 6 are as shown in the following equation (2).

(Equation 2)

[0014]
【The invention's effect】
Since the method of attaching and detaching the vertical degree display device according to the present invention is configured as described above, the following effects can be obtained.
That is, on / off of the attraction can be selected only by the rotation direction of the permanent magnet, and the attachment / detachment can be performed extremely easily and reliably. In addition, since a permanent magnet and a winding are used, suction is turned on when the power is turned off, and suction is turned off when the power is turned on, the power is not consumed at the time of suction, and a power saving type attaching / detaching mechanism can be obtained.
