Description

本発明は、開閉体が撓むおそれのある開閉装置に関するものである。   The present invention relates to an opening / closing device in which an opening / closing body may bend.

従来、この種の発明には、特許文献1に記載されているように、構造物の窓サッシの屋外側にシャッターカーテン3を配置するようにした開閉装置であって、窓サッシ側の網戸障子や、戸尻側縦框、シャッターカーテンの裏面等に緩衝材を止着したものがある。
この従来技術によれば、屋外側から強風によりシャッターカーテンが室内側へ撓んだとしても、その撓んだ際のシャッターカーテンが網戸障子やサッシ障子に直接的に当接するのを、これらの間に介在する前記緩衝材によって緩和することができる。
Conventionally, as disclosed in Patent Document 1, this kind of invention is an opening / closing device in which a shutter curtain 3 is arranged on the outdoor side of a window sash of a structure, and is a screen door shoji on the window sash side. In addition, there are some which have cushioning material fixed on the vertical side of the door and the back of the shutter curtain.
According to this prior art, even when the shutter curtain is bent indoors due to strong wind from the outdoor side, the shutter curtain at the time of bending is in direct contact with the screen door shoji and sash shoji. Can be relaxed by the cushioning material interposed between the two.

しかしながら、上記従来技術では、シャッターカーテンと網戸障子やサッシ障子との直接接触を緩衝材により阻むようにしているとはいえ、シャッターカーテンが撓み緩衝材に衝突すれば、その衝撃が網戸障子やサッシ障子等へ伝達することになる。
その上、シャッターカーテンが撓んだりばたついたりすれば、該シャッターカーテンの幅方向の端部側が、ガイドレールの内面に強く当接する場合もある。
したがって、上記従来技術においても、シャッターカーテンの撓みやばたつきに起因して、騒音の発生や各構成部材の損傷を生じるおそれがある。
However, in the above prior art, although the direct contact between the shutter curtain and the screen door shoji or sash shoji is blocked by the buffer material, if the shutter curtain bends and collides with the buffer material, the impact is screen door shoji, sash screen shoji, etc. Will be communicated to.
In addition, if the shutter curtain bends or flutters, the end side in the width direction of the shutter curtain may come into strong contact with the inner surface of the guide rail.
Therefore, also in the said prior art, there exists a possibility of producing a noise and damaging each structural member resulting from the bending and flapping of a shutter curtain.

また、他の従来技術としては、開閉体幅方向の端部側の収納位置と、開閉体幅方向の中央位置側の進出位置との間でスライドする撓み抑制部材を備え、前記進出位置にある際の前記撓み抑制部材に撓んだ開閉体が当接するようにしたものがある。
しかしながら、この従来技術では、撓み抑制部材を前記収納位置と前記進出位置との間でスライドさせる構成であるため、そのスライド空間を要する上、撓み抑制部材の収納性にも改善の余地がある。
Further, as another conventional technique, a deflection suppressing member that slides between the storage position on the end side in the opening / closing body width direction and the advance position on the center position side in the opening / closing body width direction is provided in the advance position. In some cases, the bent opening / closing body is in contact with the bending suppressing member.
However, in this prior art, since the bending suppression member is configured to slide between the storage position and the advance position, the slide space is required, and there is room for improvement in the storage performance of the bending suppression member.

Furthermore, it is preferable to set the length so as not to be cut into the guide rail 20.

また、各補強部材51,52,53の前記補強位置における開閉体開閉方向(図示例によれば上下方向)の長さは、後述する軸支部材50aが位置するスラット11a一枚分とその直上および直下のスラット11a,11aの一部を覆う長さとするのが好ましく、更に好ましくは、軸支部材50aが位置するスラット11a一枚分とその直上および直下のスラット11a,11a(計3枚分)を完全に覆う長さとするのが好ましい。   Further, the length of each reinforcing member 51, 52, 53 in the opening / closing body opening / closing direction (vertical direction according to the illustrated example) at the reinforcing position is one slat 11a on which a shaft support member 50a described later is positioned and immediately above it. It is preferable to have a length that covers a part of the slats 11a, 11a directly below, and more preferably, one slat 11a on which the shaft support member 50a is located, and slats 11a, 11a immediately above and directly below (a total of three slats 11a). ) Is preferably completely covered.

そして、各補強部材51,52,53は、その長さ方向の略中央部分に、軸支部材50aを、回動可能且つ開閉体厚さ方向にスライド可能に挿通している(図2参照)。   The reinforcing members 51, 52, and 53 are inserted through the substantially central portion in the length direction so that the shaft support member 50a can rotate and slide in the opening / closing body thickness direction (see FIG. 2). .

軸支部材50aは、頭部50a1と軸部50a2を有する略ボルト状の部材であり、その先端部をスラット11aに止着している。この軸支部材50aの軸部50a2には、環状にコイルスプリング50bが装着されている。   The shaft support member 50a is a substantially bolt-shaped member having a head portion 50a1 and a shaft portion 50a2, and a tip portion thereof is fixed to the slat 11a. An annular coil spring 50b is mounted on the shaft portion 50a2 of the shaft support member 50a.

コイルスプリング50bは、一端側座部を軸支部材50aの頭部50a1に係止するとともに、その他端側座部により各補強部材51,52,53を開閉体10面に付勢している。   The coil spring 50b engages one end side seat portion with the head portion 50a1 of the shaft support member 50a, and urges each reinforcing member 51, 52, 53 toward the opening / closing body 10 by the other end side seat portion.

したがって、各補強部材51,52,53は、コイルスプリング50bに付勢された状態でスラット11aの凹部内に位置する。
そして、各補強部材51,52,53は、開閉体10面から離れる方向(図2によれば右方向)へ引っ張られると、スラット11aの凹部外に位置することになる(図2(b)参照)。
Therefore, each reinforcement member 51, 52, 53 is located in the recessed part of the slat 11a in the state urged | biased by the coil spring 50b.
And each reinforcement member 51,52,53 will be located out of the recessed part of the slat 11a, if it pulls in the direction away from the opening-closing body 10 surface (right direction according to FIG. 2) (FIG.2 (b)). reference).

さらに、各補強部材51,52,53は、開閉体10面に沿って回動されることで、スラット11aの凹部の縁(カール部)に当接又は近接して、開閉体幅方向に対し交差した状態(図2(c)参照)の補強位置に保持される。すなわち、本実施の形態の一例によれば、図1に二点左遷で示すように、複数の補強部材51,52,53は、開閉体開閉方向(図1によれば上下方向)にわたる直線状の補強位置に保持される。   Further, each reinforcing member 51, 52, 53 is rotated along the surface of the opening / closing body 10 so as to come into contact with or close to the edge (curl portion) of the recess of the slat 11a and to the width direction of the opening / closing body. It is held at the reinforcing position in the crossed state (see FIG. 2C). That is, according to an example of the present embodiment, as shown by two points in FIG. 1, the plurality of reinforcing members 51, 52, 53 are linear in the opening / closing body opening / closing direction (vertical direction according to FIG. 1). It is held at the reinforcing position.

隣接する補強部材51,52(又は52,53)は、その一方と他方が重なり合う断面コ字状に形成される(図3参照)。すなわち、図示例によれば、開閉体開閉方向の中央側の補強部材52は、開閉体開閉方向の両側の補強部材51内及び補強部材51内に納まるコ字状に形成される。
そして、隣接する補強部材同士51,52(又は52,53)は、補強位置になった際に、コ字状に重なり合って、互いに係止し合うことになる(図3参照)。
Adjacent reinforcing members 51 and 52 (or 52 and 53) are formed in a U-shaped cross section in which one and the other overlap (see FIG. 3). That is, according to the illustrated example, the reinforcing member 52 on the center side in the opening / closing body opening / closing direction is formed in a U-shape that fits inside the reinforcing member 51 and the reinforcing member 51 on both sides in the opening / closing body opening / closing direction.
Then, the adjacent reinforcing members 51 and 52 (or 52 and 53) overlap each other in the U-shape and are locked to each other when the reinforcing position is reached (see FIG. 3).

次に、上記構成の開閉装置1について、その作用効果を述べる。   Next, the effect of the switchgear 1 having the above configuration will be described.

先ず、各補強部材51,52,53が開閉体幅方向にわたる収納位置にある状態(図1に実線で示す状態)では、各補強部材51,52,53がスラット11aの凹部内に嵌まり込んで開閉体厚さ方向へほとんど突出しない。すなわち、補強部材51,52,53は開閉体幅方向に沿って収納され回動して補強位置となるため、省スペースで収納性が良好である。
しかも、この収納位置においては、各補強部材51,52,53が隣接するスラット11a,11a間の回動を妨げることがないので、開閉体10を巻取り軸(図示せず)巻き取ったり巻き戻したりする動作を、支障なく行うことができる。
First, in a state where each reinforcing member 51, 52, 53 is in the storage position across the opening / closing body width direction (indicated by a solid line in FIG. 1), each reinforcing member 51, 52, 53 fits into the recess of the slat 11a. It hardly protrudes in the opening / closing body thickness direction. That is, the reinforcing members 51, 52, and 53 are stored along the opening / closing body width direction and rotated to become the reinforcing position, so that the space is saved and the storage property is good.
Moreover, in this storage position, the reinforcing members 51, 52, 53 do not hinder the rotation between the adjacent slats 11 a, 11 a, so that the opening / closing body 10 is wound or wound around the winding shaft (not shown). The returning operation can be performed without any trouble.

強風時には、開閉体10を全閉し、各補強部材51,52,53を開閉体10面から離れる方向へ引いて回動させる。すると、三つの補強部材51,52,53は、開閉体開閉方向へわたる直線状に連結される。そして、最上端側の補強部材51は係止部材42に係止され、最下端側の補強部材53は係止部材31に係止される。
よって、三つの補強部材51,52,53が開閉体開閉方向にわたってスラット11aの凹部の縁(カール部)に当接又は近接した状態となり(図2(c)参照)、開閉体10の厚さ方向のばたつきが、開閉方向にわたって抑制されることになる。ひいては、開閉体10のばたつきに起因した騒音や振動の発生、及び各構成部分の損傷等を防ぐことができる。
また、開閉体10のばたつきに起因してスラット11aがガイドレール20から抜け出すようなことを防ぐこともできる。
When the wind is strong, the opening / closing body 10 is fully closed, and the reinforcing members 51, 52, 53 are pulled and rotated in the direction away from the surface of the opening / closing body 10. Then, the three reinforcing members 51, 52, and 53 are connected in a straight line extending in the opening / closing body opening / closing direction. The reinforcing member 51 at the uppermost end is locked by the locking member 42, and the reinforcing member 53 at the lowermost end is locked by the locking member 31.
Therefore, the three reinforcing members 51, 52, 53 are in contact with or close to the edge (curl portion) of the recess of the slat 11 a in the opening / closing direction of the opening / closing body (see FIG. 2C). The flapping of the direction is suppressed over the opening / closing direction. As a result, it is possible to prevent the occurrence of noise and vibration due to flapping of the opening / closing body 10 and the damage of each component.
Further, it is possible to prevent the slat 11a from coming out of the guide rail 20 due to the flapping of the opening / closing body 10.

また、前記補強位置においては、最上部の補強部材51が係止部材42に係止され、最下部の補強部材53が係止部材31に係止されるため、強引に開閉体10を室外側(図1によれば奥側)へ引き出すような犯罪行為を防ぐことができる。   In the reinforcing position, the uppermost reinforcing member 51 is locked to the locking member 42 and the lowermost reinforcing member 53 is locked to the locking member 31. It is possible to prevent a criminal act to be drawn out (back side according to FIG. 1).

次に、他の実施の形態について説明する。
図5に示す開閉装置2は、上述した開閉装置1に対し、各補強部材51,52,53を、各補強部材54,55,56に置換した構成とされる。
各補強部材54,55,56は、断面略L字状を呈する長尺部材であり、スラット11aの凹部内に納まるように形成されている。
各補強部材54,55,56は、上述した各補強部材51,52,53と同様に、軸支部材50a及びコイルスプリング50bを介して、開閉体10面に枢支されている。
Next, another embodiment will be described.
The opening / closing device 2 shown in FIG. 5 has a configuration in which the reinforcing members 51, 52, 53 are replaced with the reinforcing members 54, 55, 56 with respect to the opening / closing device 1 described above.
Each of the reinforcing members 54, 55, 56 is a long member having a substantially L-shaped cross section, and is formed so as to be accommodated in the recess of the slat 11a.
The reinforcing members 54, 55, and 56 are pivotally supported on the surface of the opening / closing body 10 via the shaft support members 50a and the coil springs 50b, similarly to the reinforcing members 51, 52, and 53 described above.

隣接する補強部材54,55(又は55,56)は、開閉体開閉方向へわたる補強位置になった際、重ね合わせられた状態で、蝶螺子等の螺合部材54aにより締結される(図5(c)参照)。
また、最下部の補強部材56の下端側には、切欠部56aが設けられ、該切欠部56aは、開閉体10面に止着された係止軸13に係止される(図6参照)。係止軸13は、頭部と軸部を有する略ボルト状の部材であり、その軸部を前記切欠部56aに嵌め合わせる。
同様にして、最上部の補強部材54の上端側にも、図示しない切欠部が設けられ、該切欠部が、図示しない開閉体10面の係止軸に嵌まり合うようになっている。
The adjacent reinforcing members 54 and 55 (or 55 and 56) are fastened by a screwing member 54a such as a butterfly screw in a superposed state when the reinforcing members 54 and 55 (or 55 and 56) are in the reinforcing position in the opening / closing direction of the opening / closing body (FIG. 5). (See (c)).
Further, a cutout portion 56a is provided on the lower end side of the lowermost reinforcing member 56, and the cutout portion 56a is locked to a locking shaft 13 fixed to the surface of the opening / closing body 10 (see FIG. 6). . The locking shaft 13 is a substantially bolt-shaped member having a head portion and a shaft portion, and the shaft portion is fitted into the notch portion 56a.
Similarly, a notch not shown is also provided on the upper end side of the uppermost reinforcing member 54, and the notch fits with a locking shaft on the surface of the opening / closing body 10 not shown.

よって、図5に示す開閉装置2によれば、より簡素な構造で、効果的に開閉体10の撓みを防ぐことができる。   Therefore, according to the opening / closing device 2 shown in FIG. 5, the opening / closing body 10 can be effectively prevented from being bent with a simpler structure.

なお、開閉装置2では、補強位置にある補強部材54,56を係止軸13を介して開閉体10に係止する構成としたが、他例としては、補強位置にある補強部材54,56を係止軸13を介して収納ケース41と下枠30に止着することも可能である。
更に、他例としては、開閉装置1同様にして、補強位置にある補強部材54,56を、係止部材42,31を介して、収納ケース41と下枠30に係止させることも可能である。
In the opening / closing device 2, the reinforcing members 54, 56 at the reinforcing position are locked to the opening / closing body 10 via the locking shaft 13. However, as another example, the reinforcing members 54, 56 at the reinforcing position are used. It is also possible to fasten to the storage case 41 and the lower frame 30 via the locking shaft 13.
Furthermore, as another example, the reinforcing members 54 and 56 at the reinforcing position can be locked to the storage case 41 and the lower frame 30 via the locking members 42 and 31 in the same manner as the opening / closing device 1. is there.

また、図7は、開閉装置1における隣接する補強部材51,52(又は52,53)の接続構造の他例を示している。
すなわち、この態様では、補強部材52の端部側に、隣接する補強部材51(又は53)に対し接続するための接続部材57を設けている。
接続部材57は、補強部材52と補強部材51(又は53)との双方に嵌まり合う形状を呈し、補強部材52端部側に収納された位置と、補強部材52端部から突出して隣接する補強部材51(又は53)に嵌まり合う位置との間で、所定量スライドするように設けられる。
FIG. 7 shows another example of the connection structure of the adjacent reinforcing members 51 and 52 (or 52 and 53) in the switchgear 1.
That is, in this aspect, the connection member 57 for connecting to the adjacent reinforcement member 51 (or 53) is provided on the end side of the reinforcement member 52.
The connecting member 57 has a shape that fits both the reinforcing member 52 and the reinforcing member 51 (or 53), and is adjacent to the position accommodated on the end side of the reinforcing member 52 and the end of the reinforcing member 52. It is provided so as to slide a predetermined amount between the position where it fits into the reinforcing member 51 (or 53).

また、図8に示す態様の開閉装置3は、補強位置にある補強部材58が斜めに傾斜して開閉体10のばたつきを抑制するものである。   Moreover, the opening / closing apparatus 3 of the aspect shown in FIG. 8 suppresses the flapping of the opening-and-closing body 10 because the reinforcement member 58 in a reinforcement position inclines diagonally.

補強部材58は、開閉体幅方向に長尺な本体部58aの両端部から伸縮部58b,58bを出没させるように構成してある。   The reinforcing member 58 is configured such that the stretchable portions 58b and 58b are projected and retracted from both end portions of the main body portion 58a that is long in the opening / closing body width direction.

本体部58aは、断面コ字状や環状等、伸縮部58bを内在可能な中空長尺状であって、スラット11aの凹部に嵌まり合う部材であればよい。
この本体部58aは、上述した各補強部材51,52,53と同様に、軸支部材50a及びコイルスプリング50bを介して開閉体10面に枢支される。
The main body 58a may be a member that fits in the concave portion of the slat 11a and has a hollow long shape in which the expansion and contraction portion 58b can be contained, such as a U-shaped cross section or an annular shape.
The main body 58a is pivotally supported on the surface of the opening / closing body 10 via the shaft support member 50a and the coil spring 50b, similarly to the reinforcing members 51, 52, and 53 described above.

伸縮部58bは、本体部58aの端部側に内在される長尺部材であり、本体部58aの端部側に収納された位置と、該端部側から突出した位置との間で所定量スライドするように設けられる。   The expansion / contraction part 58b is a long member built in the end part side of the main body part 58a, and a predetermined amount between the position accommodated in the end part side of the main body part 58a and the position protruding from the end part side. It is provided to slide.

また、一方のガイドレール20の上端側と、他方のガイドレール20の下端側とには、それぞれ係止部材21が設けられる。
各係止部材21は、伸縮部58bの先端側を嵌脱可能な凹状の部材とすればよい。
Further, a locking member 21 is provided on each of the upper end side of one guide rail 20 and the lower end side of the other guide rail 20.
Each locking member 21 may be a concave member that is detachable from the distal end side of the expansion / contraction part 58b.

よって、図8に示す開閉装置3によれば、収納位置においては、補強部材58がスラット11aの凹部内に収納され、その収納性が良好である。
補強位置にするには、補強部材58を開閉体10面から離れる方向へ引き、斜めになるように回動させ、その両端側の伸縮部58b,58bをそれぞれ係止部材21に嵌め合わせればよい。補強部材58は、開閉体10面に接触又は近接して、開閉体10が厚さ方向へばたつくのを防ぐ。
Therefore, according to the opening / closing device 3 shown in FIG. 8, the reinforcing member 58 is stored in the recess of the slat 11a in the storage position, and the storage performance is good.
In order to set the reinforcing position, the reinforcing member 58 is pulled away from the surface of the opening / closing body 10, rotated so as to be inclined, and the expansion / contraction portions 58 b and 58 b on both ends thereof are fitted to the locking member 21. . The reinforcing member 58 is in contact with or close to the surface of the opening / closing body 10 and prevents the opening / closing body 10 from flapping in the thickness direction.

なお、開閉装置3の変形例としては、補強位置にある補強部材58が開閉体幅方向に対し略直交する態様とすることも可能である。この場合、補強部材58の端部は、開閉装置1と同様に収納ケース41と下枠30に係止するようにすればよい。   In addition, as a modification of the opening / closing device 3, it is possible to adopt a mode in which the reinforcing member 58 at the reinforcing position is substantially orthogonal to the opening / closing body width direction. In this case, the end portion of the reinforcing member 58 may be engaged with the storage case 41 and the lower frame 30 in the same manner as the opening / closing device 1.

また、上述した開閉装置1によれば、補強部材51,52,53を上下方向に3本設けたが、他例としては、補強部材を1本設けるようにしてもよいし、上下方向に2本又は4本以上設けるようにしてもよい。
補強部材を一本とした場合には、その一本の補強部材は、少なくとも開閉体開閉方向の中央よりに存在することが好ましい。この構成によれば、風圧等による開閉体中央部の撓みを効果的に抑制することができる。
Further, according to the opening / closing device 1 described above, the three reinforcing members 51, 52, and 53 are provided in the vertical direction, but as another example, one reinforcing member may be provided, or 2 in the vertical direction. You may make it provide a book or four or more.
When a single reinforcing member is used, the single reinforcing member is preferably present at least from the center in the opening / closing direction of the opening / closing body. According to this structure, the bending of the opening-closing body center part by a wind pressure etc. can be suppressed effectively.

前記補強部材を複数設けるようにした場合、それら複数の補強部材のうち、一番上に位置する補強部材は、収納位置における開閉体幅方向の長さを、他の補強部材よりも長くすることが好ましい。この構成によれば、軸支部材50aが比較的下よりに位置するため、補強位置にする回動操作の際に手が届きやすい。   When a plurality of the reinforcing members are provided, the uppermost reinforcing member of the plurality of reinforcing members is longer in the opening / closing body width direction at the storage position than the other reinforcing members. Is preferred. According to this configuration, since the shaft support member 50a is located relatively below, it is easy to reach when performing the turning operation to the reinforcing position.

また、前記補強部材を3以上設けるようにした場合、一番上の補強部材と一番下の補強部材以外の中間の補強部材の収納位置における開閉体幅方向の長さは、一番上の補強部材および一番下の補強部材よりも短いことが好ましい。すなわち、一番上の補強部材は、手が届きやすいように、中間の補強部材よりも長い方が好ましく、また、一番下の補強部材も、操作し易い高さ位置となるように、中間の補強部材よりも長い方が好ましい。したがって、操作性の観点からは中間の補強部材は、一番上の補強部材および一番下の補強部材よりも短くするのが好ましい。なお、補強という観点では、中間の補強部材が一番上の補強部材又は一番下の補強部材と同じか略同じ長さでもよい。   When three or more reinforcing members are provided, the length in the opening / closing body width direction at the storage position of the intermediate reinforcing member other than the uppermost reinforcing member and the lowermost reinforcing member is the uppermost. It is preferably shorter than the reinforcing member and the lowermost reinforcing member. That is, the uppermost reinforcing member is preferably longer than the intermediate reinforcing member so that it can be easily reached, and the lowermost reinforcing member is also positioned at an intermediate position so that it can be easily operated. The one longer than the reinforcing member is preferable. Therefore, from the viewpoint of operability, the intermediate reinforcing member is preferably shorter than the uppermost reinforcing member and the lowermost reinforcing member. From the viewpoint of reinforcement, the intermediate reinforcing member may have the same or substantially the same length as the uppermost reinforcing member or the lowermost reinforcing member.

また、上述した開閉装置1によれば、好ましい一例として、各補強部材51,52,53は、軸支部材50aを中心とする左右の長さを同等にしたが、補強部材の他例としては、軸支部材50aを中心とする左右の長さを異なるようにしいてもよい。この他例において、重心が長さ方向の中心からずれることにより、補強部材の水平状態が保持し難くなる場合には、止め部材等をスラット11aに設け、該止め部材によって補強部材を支持することが好ましい。なお、補強部材がスラット11aに嵌り込むことにより水平状態を保持する場合には、前記止め部材は不要である。   Further, according to the opening / closing device 1 described above, as a preferable example, the reinforcing members 51, 52, and 53 have the same left and right lengths around the shaft support member 50 a, but as other examples of the reinforcing members, The left and right lengths about the shaft support member 50a may be different. In this other example, when it becomes difficult to maintain the horizontal state of the reinforcing member due to the deviation of the center of gravity from the center in the length direction, a stopper member or the like is provided on the slat 11a and the reinforcing member is supported by the stopper member. Is preferred. When the reinforcing member is fitted into the slat 11a to maintain the horizontal state, the stop member is not necessary.

また、上述した開閉装置1によれば、開閉体10に対し一列の補強部材51,52,53を設けたが、他例としては、開閉体10に対し幅方向に間隔を置いて複数列となるように補強部材を設けるようにしてもよい。なお、開閉装置1のように、開閉体10に対し一列の補強部材を設ける場合には、その一列の補強部材は、開閉体10の幅方向の中央または中央近傍に位置するのが好ましい。
また、前記態様において、各列の補強部材は、開閉装置1のように上下方向に並ぶ複数の補強部材としてもよいし、一本の補強部材としてもよい。
In addition, according to the opening / closing device 1 described above, the reinforcing members 51, 52, 53 are provided in a row with respect to the opening / closing body 10. As another example, the opening / closing body 10 has a plurality of rows at intervals in the width direction. You may make it provide a reinforcement member so that it may become. In the case where a row of reinforcing members is provided for the opening / closing body 10 as in the opening / closing device 1, the row of reinforcing members is preferably located at the center or near the center of the opening / closing body 10 in the width direction.
Moreover, in the said aspect, the reinforcement member of each row | line | column is good also as several reinforcement members arranged in the up-down direction like the switchgear 1, and good also as one reinforcement member.
