Description

本発明は、パネルに取り付けて使用されるパネル計器の取付方法およびパネル計器の取付構造に関する。   The present invention relates to a mounting method of a panel instrument used by being attached to a panel and a mounting structure of the panel instrument.

従来より、入力機器からのデータを取り入れて出力機器の動作を制御する制御装置として、プロセスにおける温度・湿度・圧力・流量などを制御する制御装置が用いられている。   2. Description of the Related Art Conventionally, as a control device that controls the operation of an output device by taking in data from an input device, a control device that controls temperature, humidity, pressure, flow rate, and the like in a process has been used.

この制御装置は、温度・湿度・圧力・流量などの所定のパラメータを設定する操作部や制御する出力機器の状態などを表示する表示部を備え、この操作部や表示部が設けられた面を前面として制御盤などのパネルに取り付けて使用される（例えば、特許文献１〜４参照）。   This control device includes an operation unit for setting predetermined parameters such as temperature, humidity, pressure, and flow rate, and a display unit for displaying a state of an output device to be controlled, and a surface provided with the operation unit and the display unit. It is used by being attached to a panel such as a control panel as a front surface (for example, see Patent Documents 1 to 4).

なお、制御装置をパネルに取り付ける場合、制御装置全体をパネル計器として取り付ける場合もあるし、操作部や表示部が設けられた前面部を本体部と切り離して薄型のパネル計器とし、この薄型のパネル計器をパネルに取り付けて、リード線やコネクタなどで本体部と電気的に接続する場合もある。   When the control device is mounted on a panel, the entire control device may be mounted as a panel instrument, or a front panel provided with an operation section and a display section may be separated from a main body to form a thin panel instrument. In some cases, the instrument is mounted on a panel and electrically connected to the main unit with a lead wire or connector.

図１２に制御装置全体をパネル計器とした場合の取付構造を示す。図１２（ａ）は正面図、図１２（ｂ）は側面図、図１２（ｃ）は背面図である。図１３にこのパネル計器の取付構造の分解斜視図を示す。図１２および図１３において、１００はパネル計器、１０１はパネル、１０２は取付器具である。   FIG. 12 shows a mounting structure when the entire control device is a panel instrument. 12A is a front view, FIG. 12B is a side view, and FIG. 12C is a rear view. FIG. 13 is an exploded perspective view of the mounting structure of the panel instrument. 12 and 13, reference numeral 100 denotes a panel instrument, 101 denotes a panel, and 102 denotes a mounting device.

パネル計器１００は、表示・操作部（前面部）１００ａと本体部１００ｂとを備え、表示・操作部１００ａと本体部１００ｂとは一体とされている。また、表示・操作部１００ａには表示部１００ｃと操作部１００ｄとが設けられており、本体部１００ｂは表示・操作部１００ａの背面側に位置している。   The panel instrument 100 includes a display / operation unit (front surface) 100a and a main unit 100b, and the display / operation unit 100a and the main unit 100b are integrated. The display / operation unit 100a is provided with a display unit 100c and an operation unit 100d, and the main unit 100b is located on the back side of the display / operation unit 100a.

このパネル計器１００において、表示・操作部１００ａの周縁は鍔部１００ｅとされている。すなわち、表示・操作部１００ａの幅（鍔部１００ｅの幅）Ｗ１よりも本体部１００ｂの幅Ｗ２が小さくされており、これにより表示・操作部１００ａの周縁が本体部１００ｂの外側にはみ出して鍔部１００ｅとされている。また、本体部１００ｂには、制御演算回路などの回路部が収容されている。   In the panel instrument 100, the periphery of the display / operation unit 100a is a flange 100e. That is, the width W2 of the main body 100b is smaller than the width W1 of the display / operation unit 100a (the width of the flange 100e), whereby the periphery of the display / operation unit 100a protrudes outside the main body 100b and the flange is formed. The unit 100e is provided. The main body 100b houses a circuit section such as a control operation circuit.

このパネル計器の取付構造では、図１４に示すように、ＤＩＮ（Deutsche Industrie Norme）規格のパネルカット寸法に従って、パネル１０１にａ×ｂの取付用の開口（計器取付孔）１０１ａを形成する。例えば、本体部１００ｂのサイズを９１．４ｍｍ×９１．４ｍｍとした場合、９２ｍｍ（ａ）×９２ｍｍ（ｂ）の計器取付孔１０１ａを形成する。   In this panel instrument mounting structure, as shown in FIG. 14, an axb mounting opening (instrument mounting hole) 101a is formed in the panel 101 in accordance with the panel cutout size of the DIN (Deutsche Industrie Norme) standard. For example, when the size of the main body 100b is 91.4 mm x 91.4 mm, the instrument mounting hole 101a of 92 mm (a) x 92 mm (b) is formed.

そして、本体部１００ｂをこの計器取付孔１０１ａに通してパネル１０１の背面側に位置させて、本体部１００ｂの上面および下面に取付器具１０２を取り付け、この取付器具１０２に取り付けられている取付ネジ１０３の先端をパネル１０１の背面に突き当てて、締め付けることによって、パネル計器１００をパネル１０１に固定する。   Then, the main body 100b is passed through the instrument mounting hole 101a, positioned on the back side of the panel 101, and the mounting tool 102 is mounted on the upper surface and the lower surface of the main body 100b, and the mounting screw 103 mounted on the mounting tool 102 is mounted. The panel instrument 100 is fixed to the panel 101 by abutting the front end of the panel instrument on the rear surface of the panel 101 and tightening the panel instrument.

このパネル計器１００では、パネル１０１の背面に回って取付器具１０２を本体部１００ｂに取り付ける作業が必要となるが、本体部１００ｂの奥行き方向の長さが長いので、本体部１００ｂを計器取付孔１０１ａに係止させた状態でパネル１０１の背面に回っても、パネル１０１からパネル計器１００が脱落する虞はない。   In this panel instrument 100, it is necessary to turn the back surface of the panel 101 and attach the attachment 102 to the main body 100b. However, since the length of the main body 100b in the depth direction is long, the main body 100b is attached to the instrument mounting hole 101a. The panel instrument 100 does not fall off from the panel 101 even if it turns to the back of the panel 101 in a state where it is locked.

一方、前面部を本体部から切り離した薄型のパネル計器では、この薄型のパネル計器を計器取付孔１０１ａに係止させてパネル１０１の背面に回ろうとした場合、パネル１０１の背面に回るまでの間にパネル計器がパネル１０１から脱落してしまう虞がある。このため、薄型のパネル計器では、パネル計器自体にバネ状の突起などの仮固定構造を設け、計器取付孔１０１ａに仮固定するようにしている。   On the other hand, in the case of a thin panel instrument in which the front portion is separated from the main body portion, when the thin panel instrument is locked in the instrument mounting hole 101a and tries to turn to the back of the panel 101, it takes a long time to turn to the back of the panel 101. In addition, the panel instrument may fall off the panel 101. For this reason, in a thin panel instrument, a temporary fixing structure such as a spring-shaped projection is provided on the panel instrument itself, and the panel instrument is temporarily fixed to the instrument mounting hole 101a.

特開２００７−１３２８２７号公報JP 2007-132827 A 特開２０１３−２４７２４９号公報JP 2013-247249 A 特開２０１４−０３８８９２号公報JP 2014-038892 A 特開２０１２−０２８４９３号公報JP 2012-024893 A

しかしながら、薄型のパネル計器に仮固定構造を設けると、パネル計器の構造が複雑となってしまう。また、パネル計器自体に仮固定構造を設けると、パネル計器の取りはずしが困難になる。   However, if a temporary fixing structure is provided on a thin panel instrument, the structure of the panel instrument becomes complicated. In addition, if the panel instrument itself is provided with a temporary fixing structure, it becomes difficult to remove the panel instrument.

本発明は、このような課題を解決するためになされたもので、その目的とするところは、パネル計器自体に仮固定構造を設けることなく、パネルからの薄型のパネル計器の脱落を防ぐことが可能なパネル計器の取付方法およびパネル計器の取付構造を提供することにある。   The present invention has been made to solve such a problem, and an object of the present invention is to prevent a thin panel instrument from dropping off a panel without providing a temporary fixing structure on the panel instrument itself. It is an object of the present invention to provide a panel instrument mounting method and a panel instrument mounting structure.

このような目的を達成するために、本発明に係るパネル計器の取付方法（取付方法１）は、周縁に鍔部が設けられた前面部とこの前面部の背面側に位置する鍔部よりも幅の小さい機器後部とを備えたパネル計器を、機器後部をパネルに設けられた計器取付孔に嵌め込み、鍔部をパネルの前面に押し付けて、パネルに取り付けるパネル計器の取付方法であって、横幅が計器取付孔の横幅よりも短く、かつ、縦幅が計器取付孔の縦幅よりも長い取付ブラケットを、機器後部の背面内の上方に横方向に離間して設けられた少なくとも２箇所のネジ穴に取付ブラケットに形成されている貫通孔を通してネジを緩く螺着して、パネル計器に取り付ける第１工程と、パネル計器に取り付けられた取付ブラケットを機器後部の背面内の上方のネジ穴に緩く螺着されたネジの隙間を遊びとして斜めに持ち上げる第２工程と、パネルの前面側より、斜めに持ち上げた取付ブラケットの下方を計器取付孔に挿入する第３工程と、パネルの前面側より、計器取付孔に挿入した取付ブラケットの下方をパネルの背面側に落とし込みながら、取付ブラケットの上方を計器取付孔に挿入する第４工程と、パネルの前面側より、計器取付孔を通り抜けた取付ブラケットをパネルの背面側に位置させた状態で、機器後部の外周面を計器取付孔の内周面に当接させて、パネル計器をパネルに仮固定する第５工程と、パネルの背面側より、パネルに仮固定されたパネル計器の機器後部の背面内の上方のネジ穴に緩く螺着されたネジを締め付けて、また機器後部の背面内の下方に設けられているネジ穴に取付ブラケットに形成されている貫通孔を通してネジを締め付けて、取付ブラケットをパネル計器に固定する第６工程と、パネルの背面側より、パネル計器に固定された取付ブラケットをパネル計器の鍔部がパネルの前面に押し付けられるようにして固定する第７工程とを備えることを特徴とする。   In order to achieve such an object, the panel instrument mounting method according to the present invention (mounting method 1) is more effective than a front portion having a flange on the periphery and a flange located on the back side of the front portion. A panel instrument equipped with a narrow instrument rear part, a rear part of the instrument is fitted into an instrument mounting hole provided on the panel, and a flange is pressed against a front surface of the panel to thereby attach the panel instrument to the panel. A mounting bracket having a width smaller than the width of the instrument mounting hole and a height greater than the height of the instrument mounting hole, at least two screws provided in the upper part of the rear surface of the rear part of the device and spaced apart in the horizontal direction. A first step of loosely screwing a screw through a through hole formed in the mounting bracket to the hole and mounting the panel gauge on the panel instrument, and loosening the mounting bracket mounted on the panel instrument into an upper screw hole in the rear surface of the rear of the device. Screw A second step of obliquely lifting the gap between the screws as play, a third step of inserting the lower part of the mounting bracket obliquely lifted from the front side of the panel into the instrument mounting hole, and mounting the instrument from the front side of the panel. A fourth step of inserting the upper part of the mounting bracket into the instrument mounting hole while dropping the lower part of the mounting bracket inserted into the hole into the rear side of the panel, and mounting the mounting bracket passing through the instrument mounting hole from the front side of the panel to the panel.

以下、本発明の実施の形態を図面に基づいて詳細に説明する。図１に本発明の実施の形態に係るパネル計器１の正面図（図１（ａ））、側面図（図１（ｂ））および平面図（図１（ｃ））を示す。また、図２にこのパネル計器１の背面図（図１（ｂ）におけるＡ方向から見た図）を示す。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a front view (FIG. 1 (a)), a side view (FIG. 1 (b)) and a plan view (FIG. 1 (c)) of a panel instrument 1 according to an embodiment of the present invention. FIG. 2 shows a rear view of the panel instrument 1 (a view as seen from the direction A in FIG. 1B).

このパネル計器１は、表示・操作部（前面部）１ａと、この表示・操作部１ａの背面側に位置する機器後部１ｂとを備え、表示・操作部１ａと機器後部１ｂとは一体とされている。また、表示・操作部１ａには表示部１ｃと操作部１ｄとが設けられており、表示・操作部１ａの周縁は鍔部１ｅとされている。すなわち、表示・操作部１ａの幅（鍔部１ｅの幅）Ｗ１よりも機器後部１ｂの幅Ｗ２が小さくされており、これにより表示・操作部１ａの周縁が機器後部１ｂの外側にはみ出して鍔部１ｅとされている。   The panel instrument 1 includes a display / operation unit (front surface) 1a and a device rear unit 1b located on the back side of the display / operation unit 1a. The display / operation unit 1a and the device rear unit 1b are integrated. ing. The display / operation unit 1a is provided with a display unit 1c and an operation unit 1d, and the periphery of the display / operation unit 1a is a flange 1e. That is, the width W2 of the device rear portion 1b is smaller than the width (width of the flange portion 1e) W1 of the display / operation portion 1a, so that the periphery of the display / operation portion 1a protrudes outside the device rear portion 1b and the flange. It is a part 1e.

また、機器後部１ｂの背面には、計器本体（図示せず）との接続用のコネクタ１ｆが突出して設けられている。このパネル計器１を用いた場合、計器本体（本体部）は、パネル計器１とは別体として設けられる。すなわち、パネル計器１の表示・操作部１ａの背面には本体部はなく、本体部をなくすことによってパネル計器１の薄型化が図られている。   In addition, a connector 1f for connection to an instrument body (not shown) is provided protruding from the rear surface of the device rear portion 1b. When the panel instrument 1 is used, the instrument main body (main body) is provided separately from the panel instrument 1. That is, there is no main body on the back of the display / operation unit 1a of the panel instrument 1, and the panel instrument 1 is made thinner by eliminating the main body.

また、機器後部１ｂの背面には、４隅にネジ穴１ｇが形成されている。すなわち、機器後部１ｂの背面内の上方にネジ穴１ｇが横方向に離間して２箇所形成されており、下方にネジ穴１ｇが横方向に離間して２箇所形成されている。ここでは、上方の２箇所のネジ穴１ｇをｇ１，１ｇ２とし、下方のネジ穴１ｇを１ｇ３，１ｇ４とする。   Screw holes 1g are formed at four corners on the back surface of the rear portion 1b. That is, two screw holes 1g are formed in the upper part of the rear surface of the rear part 1b of the apparatus at a distance in the horizontal direction, and two screw holes 1g are formed in the lower part of the rear part of the rear part 1b. Here, the upper two screw holes 1g are g1 and 1g2, and the lower screw holes 1g are 1g3 and 1g4.

〔パネル計器の取り付け〕
図３にこのパネル計器１の取付構造を示す。図３（ａ）は正面図、図３（ｂ）は側面図、図３（ｃ）は背面図である。図４にこのパネル計器１の取付構造の分解斜視図を示す。 [Installation of panel instrument]
FIG. 3 shows a mounting structure of the panel instrument 1. 3A is a front view, FIG. 3B is a side view, and FIG. 3C is a rear view. FIG. 4 is an exploded perspective view of the mounting structure of the panel instrument 1.

図３および図４において、２はパネル、３は取付ブラケット、４は取付ブラケット３の上方および下方に取り付けられているパネル計器固定用の取付ネジ（２箇所）、５は取付ブラケット固定用のネジ（４箇所）である。   3 and 4, reference numeral 2 denotes a panel, 3 denotes a mounting bracket, 4 denotes mounting screws (two places) for fixing panel instruments mounted above and below the mounting bracket 3, and 5 denotes screws for fixing the mounting bracket. (4 places).

なお、取付ブラケット３には、ネジ５用の貫通孔３ａ（４箇所）が形成されている。また、取付ブラケット３には、この取付ブラケット３をパネル計器１の機器後部１ｂの背面に固定した際、機器後部１ｂの背面に突出しているコネクタ１ｆを通す逃げ孔の役割を果たす開口３ｂが形成されている。この例では、開口３ｂが４箇所形成されているが、その１箇所をコネクタ１ｆ用の逃げ孔として用いる。   The mounting bracket 3 has through holes 3a (four places) for the screws 5. The mounting bracket 3 has an opening 3b serving as an escape hole for passing a connector 1f protruding from the rear surface of the instrument rear portion 1b when the mounting bracket 3 is fixed to the rear surface of the instrument rear portion 1b of the panel instrument 1. Have been. In this example, four openings 3b are formed, but one of them is used as a relief hole for the connector 1f.

このパネル計器１の取付構造では、図５に示すように、ＤＩＮ規格のパネルカット寸法に従って、パネル２にａ×ｂの取付用の開口（計器取付孔）２ａを形成する。例えば、パネル計器１の機器後部１ｂのサイズを９１．４ｍｍ×９１．４ｍｍとした場合、９２ｍｍ（ａ）×９２ｍｍ（ｂ）の計器取付孔２ａを形成する。   In the mounting structure of the panel instrument 1, as shown in FIG. 5, an axb mounting opening (instrument mounting hole) 2a is formed in the panel 2 according to a DIN standard panel cut dimension. For example, when the size of the device rear portion 1b of the panel instrument 1 is 91.4 mm × 91.4 mm, the instrument mounting hole 2a of 92 mm (a) × 92 mm (b) is formed.

本実施の形態では、この計器取付孔２ａにパネル計器１の機器後部１ｂを挿入し、パネル２の背面側から取付ブラケット３を用いてパネル計器１をパネル２に固定する。この場合、図６に示すように、計器取付孔２ａにパネル計器１の機器後部１ｂを係止させてパネル２の背面に回ろうとすると、機器後部１ｂの奥行き方向の長さが短い（厚さが薄い）ために、パネル２の背面に回るまでの間にパネル計器１がパネル２から脱落してしまう可能性がある。   In the present embodiment, the instrument rear portion 1b of the panel instrument 1 is inserted into the instrument mounting hole 2a, and the panel instrument 1 is fixed to the panel 2 using the mounting bracket 3 from the rear side of the panel 2. In this case, as shown in FIG. 6, when the instrument rear portion 1b of the panel instrument 1 is locked in the instrument mounting hole 2a and the panel instrument 1 is to be rotated to the back of the panel 2, the length of the instrument rear portion 1b in the depth direction is short (thickness). Therefore, there is a possibility that the panel instrument 1 may fall off the panel 2 before turning to the back of the panel 2.

そこで、本実施の形態では、取付ブラケット３の横幅ｃを計器取付孔２ａの横幅ａよりも短く（ｃ＜ａ）、かつ、縦幅ｄを計器取付孔２ａの縦幅ｂよりも長くし（ｄ＞ｂ）、先に取付ブラケット３をパネル計器１の機器後部１ｂの背面の上方に緩くネジ止めし、この緩くネジ止めされた取付ブラケット３をパネル２の前面側から計器取付孔２ａに挿入して通り抜けさせてパネル２の背面側に位置させるとともに、パネル計器１の機器後部１ｂを計器取付孔２ａに係止させて仮固定するものとし、この仮固定した状態でパネル２の背面側から取付ブラケット３を用いてパネル計器１をパネル２に固定するようにしている。   Therefore, in the present embodiment, the width c of the mounting bracket 3 is shorter than the width a of the instrument mounting hole 2a (c <a), and the height d is longer than the height b of the instrument mounting hole 2a ( d> b) First, the mounting bracket 3 is loosely screwed above the rear surface of the instrument rear portion 1b of the panel instrument 1, and the loosely screwed mounting bracket 3 is inserted into the instrument mounting hole 2a from the front side of the panel 2. To be positioned on the back side of the panel 2 and to temporarily fix the instrument rear portion 1b of the panel instrument 1 by locking it in the instrument mounting hole 2a, and from the rear side of the panel 2 in this temporarily fixed state. The panel instrument 1 is fixed to the panel 2 using the mounting bracket 3.

図８に取付ブラケット３の側面図（図８（ａ））および背面図（図８（ｂ））を示す。この取付ブラケット３は、上述したように、横幅ｃが計器取付孔２ａの横幅ａよりも短く、縦幅ｄが計器取付孔２ａの縦幅ｂよりも長くされている。また、ネジ５用の貫通孔３ａが上方に２箇所、下方に２箇所、合計４箇所形成されている。ここでは、上方の２箇所の貫通孔３ａを３ａ１，３ａ２とし、下方の２箇所の貫通孔３ａを３ａ３，３ａ４とする。   FIG. 8 shows a side view (FIG. 8A) and a rear view (FIG. 8B) of the mounting bracket 3. As described above, the mounting bracket 3 has a width c that is shorter than the width a of the instrument mounting hole 2a and a height d that is longer than the height b of the instrument mounting hole 2a. In addition, four through holes 3a for the screw 5 are formed at two places above and two places below. Here, the upper two through holes 3a are 3a1 and 3a2, and the lower two through holes 3a are 3a3 and 3a4.

この取付ブラケット３において、上方の貫通孔３ａ１および３ａ２は、パネル計器１の機器後部１ｂの背面に形成されている上方のネジ穴１ｇ１および１ｇ２に対応する位置に形成されており、下方の貫通孔３ａ３および３ａ４はパネル計器１の機器後部１ｂの背面に形成されている下方のネジ穴１ｇ３および１ｇ４に対応する位置に形成されている。また、取付ブラケット３には、機器後部１ｂの背面に突出しているコネクタ１ｆを通す逃げ孔の役割を果たす開口３ｂが４箇所形成されており、上方および下方の鍔面３ｃ（３ｃ１，３ｃ２）にはパネル計器固定用の取付ネジ４が取り付けられている。   In this mounting bracket 3, the upper through holes 3a1 and 3a2 are formed at positions corresponding to the upper screw holes 1g1 and 1g2 formed on the back surface of the instrument rear portion 1b of the panel instrument 1, and the lower through holes are formed. 3a3 and 3a4 are formed at positions corresponding to the lower screw holes 1g3 and 1g4 formed on the back surface of the instrument rear portion 1b of the panel instrument 1. Further, the mounting bracket 3 is formed with four openings 3b serving as escape holes for passing a connector 1f protruding from the rear surface of the device rear portion 1b, and is formed on upper and lower flange surfaces 3c (3c1, 3c2). Is provided with a mounting screw 4 for fixing a panel instrument.

以下、この取付ブラケット３を用いたパネル２へのパネル計器１の取付方法について、具体的に説明する。   Hereinafter, a method of mounting the panel instrument 1 to the panel 2 using the mounting bracket 3 will be specifically described.

〔パネル計器の取付方法の第１例〕
先ず、取付ブラケット３を用いたパネル２へのパネル計器１の取付方法の第１例について、図７Ａ〜図７Ｈを用いて説明する。 [First example of mounting method of panel instrument]
First, a first example of a method of attaching panel instrument 1 to panel 2 using attachment bracket 3 will be described with reference to FIGS. 7A to 7H.

〔第１工程：図７Ａ〕
第１工程では、 図７Ａに示すように、パネル計器１の機器後部１ｂの背面内の上方のネジ穴１ｇ１，１ｇ２に、取付ブラケット３に形成されている貫通孔３ａ１，３ａ２を通してネジ５，５を緩く螺着して、取付ブラケット３をパネル計器１に取り付ける。 [First step: FIG. 7A]
In the first step, as shown in FIG. 7A, screws 5 and 5 are inserted through through holes 3a1 and 3a2 formed in the mounting bracket 3 into upper screw holes 1g1 and 1g2 in the rear surface of the instrument rear portion 1b of the panel instrument 1. And the mounting bracket 3 is mounted on the panel instrument 1.

この例では、ネジ５，５の首下と取付ブラケット３との間に０．５ｍｍ程度の隙間が生じるように、ネジ５，５を貫通孔３ａ１，３ａ２を通してネジ穴１ｇ１，１ｇ２に緩く螺着する。   In this example, the screws 5 are loosely screwed into the screw holes 1g1 and 1g2 through the through holes 3a1 and 3a2 so that a gap of about 0.5 mm is formed between the neck of the screws 5 and 5 and the mounting bracket 3. I do.

〔第２工程：図７Ｂ〕
第２工程では、図７Ｂに示すように、機器後部１ｂの背面内の上方のネジ穴１ｇ１，１ｇ２に緩く螺着されたネジ５，５の隙間を遊びとして、パネル計器１に取り付けられた取付ブラケット３を斜めに持ち上げる。 [Second step: FIG. 7B]
In the second step, as shown in FIG. 7B, the mounting attached to the panel instrument 1 with the gap between the screws 5, 5 loosely screwed into the upper screw holes 1g1, 1g2 in the back surface of the equipment rear portion 1b as play. Lift the bracket 3 diagonally.

すなわち、機器後部１ｂの背面内の上方のネジ穴１ｇ１，１ｇ２にネジ５，５を緩く螺着しているので、ネジ５，５の首下と取付ブラケット３との間の隙間だけ取付ブラケット３を斜めに持ち上げることができる。この例では、１０゜程度（α≒１０゜）、取付ブラケット３を持ち上げる。なお、パネル２にパネル計器１と取付ブラケット３を挟み込めるだけの隙間ができるようにすればよく、斜めに持ち上げる角度αは１０゜程度に限られるものではない。   That is, the screws 5, 5 are loosely screwed into the upper screw holes 1g1, 1g2 in the rear surface of the rear part 1b of the device, so that the mounting bracket 3 is only a gap between the lower part of the screws 5, 5 and the mounting bracket 3. Can be lifted diagonally. In this example, the mounting bracket 3 is lifted by about 10 ° (α ≒ 10 °). It is sufficient that a gap is provided in the panel 2 so that the panel instrument 1 and the mounting bracket 3 can be sandwiched therebetween, and the angle α at which the panel is lifted obliquely is not limited to about 10 °.

〔第３工程：図７Ｃ〕
第３工程では、図７Ｃに示すように、パネル２の前面側より、斜めに持ち上げた取付ブラケット３の下方を計器取付孔２ａに挿入する。すなわち、取付ブラケット３が取り付けられたパネル計器１全体を上に持ち上げ、斜めとされている取付ブラケット３の下方を計器取付孔２ａに挿入する。取付ブラケット３は、その横幅ｃが計器取付孔２ａの横幅ａよりも短くされているので、取付ブラケット３の下方を計器取付孔２ａに挿入することができる。 [Third step: FIG. 7C]
In the third step, as shown in FIG. 7C, the lower part of the mounting bracket 3 which is lifted obliquely from the front side of the panel 2 is inserted into the instrument mounting hole 2a. That is, the entire panel instrument 1 to which the mounting bracket 3 is attached is lifted up, and the lower part of the oblique mounting bracket 3 is inserted into the instrument mounting hole 2a. Since the width c of the mounting bracket 3 is shorter than the width a of the instrument mounting hole 2a, the lower part of the mounting bracket 3 can be inserted into the instrument mounting hole 2a.

〔第４工程：図７Ｄ〕
第４工程では、図７Ｄに示すように、パネル２の前面側より、計器取付孔２ａに挿入した取付ブラケット３の下方をパネル２の背面側に落とし込みながら、取付ブラケット３の上方を計器取付孔２ａに挿入する。すなわち、取付ブラケット３が取り付けられたパネル計器１全体を下に下げ、取付ブラケット３の上方を潜らせるようにして計器取付孔２ａに挿入する。 [Fourth step: FIG. 7D]
In the fourth step, as shown in FIG. 7D, the lower part of the mounting bracket 3 inserted into the instrument mounting hole 2a is dropped on the rear side of the panel 2 from the front side of the panel 2 while the upper part of the mounting bracket 3 is attached to the instrument mounting hole. 2a. That is, the entire panel instrument 1 to which the mounting bracket 3 is attached is lowered, and the panel instrument 1 is inserted into the instrument mounting hole 2a so as to dive above the mounting bracket 3.

〔第５工程：図７Ｅ〕
第５工程では、図７Ｅに示すように、計器取付孔２ａを通り抜けた取付ブラケット３をパネル計器１とともに持ち上げて、パネル計器１の機器後部１ｂの外周面１ｈを計器取付孔２ａの内周面２ｂに当接させる。機器後部１ｂの外径は計器取付孔２ａの内径よりも僅かに小さくされているので、機器後部１ｂの外周面１ｈの下側の端面（底面）と計器取付孔２ａの内周面２ｂの下側の端面（底面）とが当接する。これにより、パネル計器１がパネル２に仮固定される。 [Fifth step: FIG. 7E]
In the fifth step, as shown in FIG. 7E, the mounting bracket 3 having passed through the instrument mounting hole 2a is lifted together with the panel instrument 1, and the outer peripheral surface 1h of the instrument rear portion 1b of the panel instrument 1 is fixed to the inner peripheral surface of the instrument mounting hole 2a. 2b. Since the outer diameter of the rear portion 1b of the instrument is slightly smaller than the inner diameter of the instrument mounting hole 2a, the lower end surface (bottom surface) of the outer peripheral surface 1h of the instrument rear portion 1b and the inner peripheral surface 2b of the instrument mounting hole 2a are lower. Side end surface (bottom surface). Thereby, panel instrument 1 is temporarily fixed to panel 2.

この仮固定された状態では、パネル計器１の鍔部１ｅと取付ブラケット３との間にパネル２が挟まり、取付ブラケット３や鍔部１ｅがパネル２に引っ掛かるため、パネル計器１の機器後部１ｂが計器取付孔２ａから脱落する可能性は少ない。   In this temporarily fixed state, the panel 2 is sandwiched between the flange 1e of the panel instrument 1 and the mounting bracket 3, and the mounting bracket 3 and the flange 1e are hooked on the panel 2, so that the equipment rear portion 1b of the panel instrument 1 The possibility of falling off from instrument mounting hole 2a is small.

仮に、パネル計器１の機器後部１ｂが計器取付孔２ａから脱落したとしても、図７Ｈに示されるように、脱落したパネル計器１の機器後部１ｂと取付ブラケット３との間の隙間で計器取付孔２ａの底部（周縁）が挟まれるため、パネル計器１がパネル２から完全に落下してしまうということはない。   Even if the instrument rear portion 1b of the panel instrument 1 falls off from the instrument mounting hole 2a, as shown in FIG. 7H, the instrument mounting hole is formed in the gap between the instrument instrument rear portion 1b of the panel instrument 1 and the mounting bracket 3 as shown in FIG. Since the bottom (peripheral edge) of 2a is sandwiched, the panel instrument 1 does not completely fall off the panel 2.

〔第６工程：図７Ｆ〕
第６工程では、図７Ｆに示すように、パネル２の背面に回り、このパネル２の背面側より、パネル２に仮固定されているパネル計器１の機器後部１ｂのネジ穴１ｇ１，１ｇ２に緩く螺着されているネジ５，５を締め付けて、また機器後部１ｂのネジ穴１ｇ３，１ｇ４に貫通孔３ａ２，３ａ４を通してネジ５，５を締め付けて、取付ブラケット３をパネル計器１に固定する。 [Sixth step: FIG. 7F]
In the sixth step, as shown in FIG. 7F, the panel instrument 1 goes around the rear surface of the panel 2 and loosens from the rear side of the panel 2 into the screw holes 1g1 and 1g2 of the instrument rear portion 1b of the panel instrument 1 temporarily fixed to the panel 2. The mounting bracket 3 is fixed to the panel instrument 1 by tightening the screws 5, 5 which are screwed in and through the through holes 3a2, 3a4 in the screw holes 1g3, 1g4 of the rear part 1b of the device.

〔第７工程：図７Ｇ〕
第７工程では、図７Ｇに示すように、パネル２の背面側より、取付ブラケット３の上方および下方に取り付けられている取付ネジ４を回し、この取付ネジ４の先端をパネル２の背面に突き当てて、締め付けることによって、パネル計器１をパネル２に固定する。すなわち、パネル２の背面側から取付ネジ４を締め付けることによって、パネル２とパネル計器１との間にネジ軸力の反力を生じさせ、パネル計器１をパネル２に固定する。 [Seventh step: FIG. 7G]
In the seventh step, as shown in FIG. 7G, the mounting screws 4 mounted above and below the mounting bracket 3 are turned from the back side of the panel 2, and the tips of the mounting screws 4 are protruded toward the back surface of the panel 2. The panel instrument 1 is fixed to the panel 2 by hitting and tightening. That is, by tightening the mounting screw 4 from the rear side of the panel 2, a reaction force of a screw axial force is generated between the panel 2 and the panel instrument 1, and the panel instrument 1 is fixed to the panel 2.

この取付ブラケット３を用いたパネル計器１のパネル２への固定状態を図９に拡大して示す。図９（ａ）は側面図、図９（ｂ）は背面図であり、取付ネジ４を締め付けるとパネル２とパネル計器１との間にネジ軸力の反力が生じるため、パネル計器１の鍔部１ｅがパネル２の前面に押し付けられ、このパネル計器１の鍔部１ｅと取付ブラケット３との間に挟まれてパネル計器１がパネル２に固定される。   FIG. 9 is an enlarged view of a state where the panel instrument 1 is fixed to the panel 2 using the mounting bracket 3. FIG. 9A is a side view, and FIG. 9B is a rear view. When the mounting screw 4 is tightened, a reaction force of a screw axial force is generated between the panel 2 and the panel instrument 1. The flange 1e is pressed against the front surface of the panel 2, and the panel gauge 1 is fixed to the panel 2 by being sandwiched between the flange 1e of the panel gauge 1 and the mounting bracket 3.

以上の説明から分かるように、このパネル計器の取付方法の第１例では、計器取付孔２ａに取付ブラケット３を挿入して通り抜けさせ、この計器取付孔２ａを通り抜けた取付ブラケット３をパネル２の背面側に位置させた状態で、機器後部１ｂの外周面１ｈを計器取付孔２ａの内周面２ｂに当接させるようにして、パネル計器１をパネル２に仮固定するようにしているので、パネル計器１自体に仮固定構造を設けることなく、パネル２からのパネル計器１（薄型のパネル計器）の脱落を防ぐことができるようになる。   As can be seen from the above description, in the first example of the panel instrument mounting method, the mounting bracket 3 is inserted into the instrument mounting hole 2a and passed therethrough. Since the outer peripheral surface 1h of the instrument rear portion 1b is brought into contact with the inner peripheral surface 2b of the instrument mounting hole 2a in a state where the panel instrument 1 is positioned on the back side, the panel instrument 1 is temporarily fixed to the panel 2. The panel instrument 1 (thin panel instrument) can be prevented from falling off from the panel 2 without providing a temporary fixing structure on the panel instrument 1 itself.

〔パネル計器の取付方法の第２例〕
次に、取付ブラケット３を用いたパネル２へのパネル計器１の取付方法の第２例について、図１０Ａ〜図１０Ｈを用いて説明する。 [Second example of mounting method of panel instrument]
Next, a second example of a method of attaching the panel instrument 1 to the panel 2 using the attachment bracket 3 will be described with reference to FIGS. 10A to 10H.

図１０Ａ〜図１０Ｄまでの工程（第１工程〜第４工程）は、上述したパネル計器の取付方法の第１例で説明した図７Ａ〜図７Ｄまでの工程（第１工程〜第４工程）と同じであるのでその説明は省略する。   The steps from FIG. 10A to FIG. 10D (first step to fourth step) are the steps from FIG. 7A to FIG. 7D (first step to fourth step) described in the first example of the panel instrument mounting method described above. Therefore, the description is omitted.

このパネル計器の取付方法の第２例では、第４工程（図１０Ｄ）において取付ブラケット３の上方を潜らせるようにして計器取付孔２ａに挿入した後、取付ブラケット３を上に持ち上げるのではなく、そのまま落下させる。   In the second example of the method of mounting the panel instrument, in the fourth step (FIG. 10D), after inserting the instrument into the instrument mounting hole 2a so as to go under the mounting bracket 3, the mounting bracket 3 is not lifted up. And let it fall.

この場合、図１０Ｅに示すように、パネル計器１の機器後部１ｂと取付ブラケット３との間の隙間で計器取付孔２ａの底部（周縁）が挟まれ、それ以上の取付ブラケット３の落下が阻止される。この状態をパネル計器１がパネル２に仮固定された状態とする（図１０Ｅ（第５工程））。   In this case, as shown in FIG. 10E, the bottom (peripheral edge) of the instrument mounting hole 2a is sandwiched by the gap between the instrument rear portion 1b of the panel instrument 1 and the mounting bracket 3, and the mounting bracket 3 is prevented from dropping further. Is done. In this state, the panel instrument 1 is temporarily fixed to the panel 2 (FIG. 10E (fifth step)).

すなわち、パネル計器の取付方法の第２例では、パネル計器の取付方法の第１例における図７Ｈに示された状態（パネル計器１の機器後部１ｂが計器取付孔２ａから脱落した状態）を作り出し、この状態を仮固定された状態とする。   That is, in the second example of the panel instrument mounting method, the state shown in FIG. 7H in the first example of the panel instrument mounting method (a state in which the instrument rear portion 1b of the panel instrument 1 is dropped from the instrument mounting hole 2a) is created. This state is referred to as a temporarily fixed state.

そして、パネル２の背面に回り、このパネル２の背面側より、取付ブラケット３をパネル計器１とともに持ち上げて、機器後部１ｂの外周面１ｈを計器取付孔２ａの内周面２ｂに当接させる（図１０Ｆ（第６工程））。これにより、パネル２の背面側において、パネル計器１がパネル２に係止される。   Then, the mounting bracket 3 is lifted together with the panel gauge 1 from the back side of the panel 2 so that the outer peripheral surface 1h of the instrument rear part 1b is brought into contact with the inner peripheral surface 2b of the gauge mounting hole 2a from the rear side of the panel 2 (FIG. FIG. 10F (sixth step)). As a result, the panel instrument 1 is locked to the panel 2 on the rear side of the panel 2.

この後、図７Ｆ、図７Ｇと同様にして、パネル計器１をパネル２に固定する。すなわち、パネル２に係止されているパネル計器１の機器後部１ｂの背面にネジ５を締め付けることによって取付ブラケット３を固定し（図１０Ｇ（第７工程））、取付ブラケット３の上方および下方に取り付けられている取付ネジ４を締め付けることによってパネル計器１をパネル２に固定する（図１０Ｈ（第８工程））。   Thereafter, panel instrument 1 is fixed to panel 2 in the same manner as in FIGS. 7F and 7G. That is, the mounting bracket 3 is fixed by tightening the screw 5 on the back surface of the instrument rear portion 1b of the panel instrument 1 locked to the panel 2 (FIG. 10G (seventh step)). The panel instrument 1 is fixed to the panel 2 by tightening the attached mounting screws 4 (FIG. 10H (eighth step)).

以上の説明から分かるように、このパネル計器の取付方法の第２例では、計器取付孔２ａに取付ブラケット３を挿入して通り抜けさせ、この計器取付孔２ａを通り抜けた取付ブラケット３をパネル２の背面側に脱落させ、このパネル２の背面側に脱落させた取付ブラケット３とパネル２の前面側に位置する機器後部１ｂとの隙間で計器取付孔２ａの底部（周縁）を挾むようにして、パネル計器１をパネル２に仮固定するようにしているので、パネル計器１自体に仮固定構造を設けることなく、パネル２からのパネル計器１（薄型のパネル計器）の脱落を防ぐことができるようになる。   As can be seen from the above description, in the second example of the panel instrument mounting method, the mounting bracket 3 is inserted into the instrument mounting hole 2a and passed therethrough, and the mounting bracket 3 that has passed through the instrument mounting hole 2a is The panel instrument is dropped to the rear side, and the bottom (peripheral edge) of the instrument mounting hole 2a is sandwiched between the mounting bracket 3 dropped to the rear side of the panel 2 and the equipment rear portion 1b located on the front side of the panel 2. Since the panel instrument 1 is temporarily fixed to the panel 2, the panel instrument 1 (thin panel instrument) can be prevented from falling off from the panel 2 without providing a temporary fixing structure on the panel instrument 1 itself. .

なお、上述した実施の形態では、パネル計器１に固定する前に取付ブラケット３に取付ネジ４を取り付けておくようにしたが、パネル２の背面に回った後に取付ブラケット３に取付ネジ４を取り付けて、締め付けるようにしてもよい。   In the above-described embodiment, the mounting screw 4 is mounted on the mounting bracket 3 before fixing to the panel instrument 1. However, the mounting screw 4 is mounted on the mounting bracket 3 after turning to the back of the panel 2. And may be tightened.

また、上述した実施の形態では、取付ブラケット３を上方２箇所、下方２箇所、合計４箇所でパネル計器１の機器後部１ｂの背面にネジ５で固定するようにしたが、必ずしも４箇所に限られるものではない。すなわち、上方は取付ブラケット３の回り止めを行うものとして少なくとも２箇所あればよく、下方は１箇所であっても構わない。   Further, in the above-described embodiment, the mounting bracket 3 is fixed to the rear surface of the instrument rear portion 1b of the panel instrument 1 with the screw 5 at the upper two places and the lower two places, for a total of four places. Is not something that can be done. In other words, the upper part may be at least two places for stopping the rotation of the mounting bracket 3, and the lower part may be one place.

また、上述した実施の形態では、パネル計器１の鍔部１ｅの背面をパネル２の前面に当接させるようにしてパネル計器１をパネル２に取り付けるようにしているが、図１１に示すように、パネル計器１の鍔部１ｅの背面と計器取付孔２ａの縁面との間にガスケット６を介在させるようにしてもよい。このようにすると、パネル計器１の鍔部１ｅの背面と計器取付孔２ａの縁面とでガスケット６が挾圧され、この挾圧された面がシール面となって、パネル計器１の鍔部１ｅとパネル２との隙間が塞がれ、防水・防塵の機能が保障される。   Further, in the above-described embodiment, the panel instrument 1 is attached to the panel 2 such that the back surface of the flange 1e of the panel instrument 1 is brought into contact with the front face of the panel 2, but as shown in FIG. The gasket 6 may be interposed between the back surface of the flange 1e of the panel instrument 1 and the edge of the instrument mounting hole 2a. In this manner, the gasket 6 is clamped between the back surface of the flange 1e of the panel instrument 1 and the edge of the instrument mounting hole 2a, and the clamped surface becomes a sealing surface. The gap between 1e and panel 2 is closed, and the waterproof and dustproof functions are guaranteed.

また、上述した実施の形態では、パネル計器１の表示・操作部１ａに表示部１ｃと操作部１ｄとが設けられているものとしたが、表示部１ｃだけが設けられていてもよく、操作部１ｄだけが設けられていてもよい。   In the above-described embodiment, the display / operation unit 1a of the panel instrument 1 is provided with the display unit 1c and the operation unit 1d. However, only the display unit 1c may be provided. Only the portion 1d may be provided.
