Description

本発明は、電磁波を遮蔽する必要のある部屋の出入口などに適用する引き戸に関し、特に、両開きに構成した2枚の引き戸本体の召し合わせ部分において漏洩しがちな電磁波を確実にシールドすることができる電磁波シールド引き戸に関するものである。   The present invention relates to a sliding door applied to an entrance / exit of a room where electromagnetic waves need to be shielded, and in particular, can reliably shield electromagnetic waves that are likely to leak at the summing portion of two sliding door bodies configured in double doors. The present invention relates to an electromagnetic shielding door.

電磁波シールドの必要な環境として、例えば、放電加工室、脳波測定室、MRI室、放送スタジオ、空港レーダー管制室、コンピュータ室などがあり、このような電磁波シールドを必要とする部屋は、天井、壁、床、ドアなど、部屋全体に電磁波シールド材料(導電性材料)を使用して電磁波の遮蔽率を高める必要があり、場合によっては、窓に電磁波シールドガラスが使用される場合もある。特に、ドア部分は開閉動作を伴うため、電磁波シールドに工夫を要する部分である。   Examples of environments that require electromagnetic shielding include an electric discharge machining room, an electroencephalogram measurement room, an MRI room, a broadcast studio, an airport radar control room, a computer room, and the like. It is necessary to increase the shielding rate of electromagnetic waves by using an electromagnetic shielding material (conductive material) for the entire room, such as a floor and a door. In some cases, electromagnetic shielding glass is used for windows. In particular, since the door part is accompanied by an opening / closing operation, the electromagnetic wave shield is a part that needs to be devised.

このような電磁波シールドを必要とする部屋のドアに引き戸を採用する場合には、スライドする機構が必要であるため、上部の鴨居部分と下部の敷居部分での電磁波のシールドを如何に行うかというのが問題となる。シールドを完全とするためには導電性材料で密閉する必要があるが、導電性材料を密着させた状態で引き戸をスライドさせると、シールドの効果は得られるものの常に摩擦が生じてしまい、これが故障等の原因となるという問題がある。よって、引き戸をスライドさせる場合には引き戸と室内開口部を構成する電磁波シールド材料同士が接触しない状態であることが望ましい。   When a sliding door is used for a door in a room that requires such an electromagnetic shield, a sliding mechanism is required, so how to shield electromagnetic waves at the upper duck part and the lower sill part. Is a problem. In order to complete the shield, it is necessary to seal with a conductive material, but sliding the sliding door with the conductive material in close contact will always produce friction, but this will cause a failure. There is a problem of causing this. Therefore, when sliding the sliding door, it is desirable that the electromagnetic shielding materials constituting the sliding door and the indoor opening are not in contact with each other.

この接触による摩擦の問題を課題とした従来技術として、特許文献1が既に提案されている。この特許文献1に記載の電磁波遮蔽引き戸は、引き戸本体と壁や床の構造部との境界部分に、電磁波を迂回させることによって減衰させる中空間構造を備えるようにしたものであり、中空間構造は、例えば、鴨居部に羽根部を設け、引き戸本体に該羽根部が作る空間に非接触で入り込むような羽根部を設けることにより、形成したものである。   Patent Document 1 has already been proposed as a conventional technique which has a problem of friction due to this contact. The electromagnetic wave shielding sliding door described in Patent Document 1 is provided with an intermediate space structure that attenuates electromagnetic waves by detouring at a boundary portion between the sliding door main body and the structure of the wall or floor. Is formed, for example, by providing a wing portion in the head portion and providing a wing portion in the sliding door body so as to enter the space created by the wing portion in a non-contact manner.

ここで、図8を用いて、従来技術である特許文献1に記載の電磁波遮蔽引き戸の各部の構成を説明する。図8(a)は、鴨居部分の詳細な構成を表した断面図である。この図8(a)に示すように、壁構造部14に、断面がL字型の支持枠17が固着されており、この支持枠17の引き戸側の内側には、断面がF字形の部材19が固着されている。また、壁構造部14の支持枠17と反対の側には、引き戸本体10を懸架するためのレール支持枠15が固着されており、このレール支持枠15の内側にはレール部16が形成されている。   Here, the configuration of each part of the electromagnetic wave shielding sliding door described in Patent Document 1 which is the prior art will be described with reference to FIG. Fig.8 (a) is sectional drawing showing the detailed structure of the Kamoi part. As shown in FIG. 8A, a support frame 17 having an L-shaped cross section is fixed to the wall structure portion 14, and a member having an F-shaped cross section is provided inside the sliding frame side of the support frame 17. 19 is fixed. A rail support frame 15 for suspending the sliding door body 10 is fixed to the side of the wall structure portion 14 opposite to the support frame 17, and a rail portion 16 is formed inside the rail support frame 15. ing.

一方、引き戸本体10の上縁部にはL字形部材11が固着され、該L字形部材11に軸12を設けるとともに、該軸12に回動可能に滑車13を取り付ける。上述のレール部16上に滑車13が当接するようにして、引き戸本体10を懸架する。また、引き戸本体10の上縁部には、断面がL字形の部材18が固着されており、引き戸本体10がレール部16に懸架された状態で、F字形部材19の2つの羽根部19a、19bの間の中空部分にL字形部材18の羽根部18aが非接触で入り込むように、寸法が調整されている。これらのF字形部材19及びL字形部材18が導電性の素材で構成され、かつ、これらの間に中空部20が形成されていることにより、電磁波を迂回させてシールドとしての効果を発揮する。   On the other hand, an L-shaped member 11 is fixed to the upper edge of the sliding door body 10, and a shaft 12 is provided on the L-shaped member 11, and a pulley 13 is attached to the shaft 12 so as to be rotatable. The sliding door main body 10 is suspended so that the pulley 13 abuts on the rail portion 16 described above. In addition, an L-shaped member 18 is fixed to the upper edge portion of the sliding door body 10, and the two blade portions 19 a of the F-shaped member 19 in a state where the sliding door body 10 is suspended from the rail portion 16, The dimension is adjusted so that the blade | wing part 18a of the L-shaped member 18 may enter into the hollow part between 19b non-contactingly. The F-shaped member 19 and the L-shaped member 18 are made of a conductive material, and the hollow portion 20 is formed between them, so that the electromagnetic wave is bypassed and the effect as a shield is exhibited.

図8(b)は、戸袋部分の詳細な構成を表した断面図である。この図8(b)に示すように、戸袋壁22の端部に設けられた戸袋支柱21に導電性の素材で構成した断面がL字形状の部材23を固着し、引き戸本体10の戸袋側の側辺に導電性の素材で構成した断面がL字形状の部材24を固着する。引き戸を閉めた状態で、L字形状部材23の板部23aと戸袋支柱21との間に、L字形状部材24の板部24aが入り込み、これにより中空部20を形成して、電磁波を迂回させてシールドとしての効果を発揮する。   FIG.8 (b) is sectional drawing showing the detailed structure of the door pocket part. As shown in FIG. 8 (b), an L-shaped member 23 composed of a conductive material is fixed to a door pocket support 21 provided at the end of the door pocket wall 22, and the door side of the sliding door body 10 is fixed. A member 24 having an L-shaped cross section made of a conductive material is fixed to the side of the plate. With the sliding door closed, the plate portion 24a of the L-shaped member 24 enters between the plate portion 23a of the L-shaped member 23 and the door support column 21, thereby forming a hollow portion 20 to bypass the electromagnetic wave. Let me demonstrate the effect as a shield.

図8(c)は、敷居部分の詳細な構成を表した断面図である。この図8(c)に示すように、床面25の敷居部分には、断面が方形状になる溝部30が形成され、この溝部30の底面上に、導電性の素材で構成された2つのL字形状部材28を開口部が形成されるように配置し、L字形状部材28のそれぞれの上には、適当な個所に振れ止め用の滑車29を設ける。また、溝部30の上部には、蓋部26を開口部が形成されるようにして配置する。   FIG.8 (c) is sectional drawing showing the detailed structure of the threshold part. As shown in FIG. 8C, a groove portion 30 having a square cross section is formed in the sill portion of the floor surface 25. On the bottom surface of the groove portion 30, two conductive materials made of a conductive material are formed. An L-shaped member 28 is arranged so that an opening is formed, and a pulley 29 for steadying is provided on each of the L-shaped members 28 at an appropriate position. Further, the lid portion 26 is disposed on the upper portion of the groove portion 30 so as to form an opening.

一方、引き戸本体10の底辺部には、導電性の素材で構成された断面が逆T字形状の部材27が固着されており、この逆T字形状の部材27は、引き戸本体10の底辺から伸びる鉛直板部27aが蓋部26とL字形状部材28のそれぞれの開口部を通り、先端の水平板部27bがL字形状部材28によって作られる部屋の中に入るようにして配置する。これにより中空部20を形成して、電磁波を迂回させてシールドとしての効果を発揮する。   On the other hand, an inverted T-shaped member 27 made of a conductive material is fixed to the bottom side of the sliding door body 10, and the inverted T-shaped member 27 extends from the bottom of the sliding door body 10. The extending vertical plate portion 27 a passes through the openings of the lid portion 26 and the L-shaped member 28, and the horizontal plate portion 27 b at the tip is placed in a room made by the L-shaped member 28. Thereby, the hollow part 20 is formed, and the effect as a shield is exhibited by detouring the electromagnetic wave.

この特許文献1に記載の電磁波遮蔽引き戸によれば、スライド時においてもドアを閉じた場合においても電磁波シールド材料が接触することがなく、上述の摩擦による問題は解消することができる。しかし、ドアを閉じた場合においても電磁波シールド材料が非接触であるため、シールドが不完全であるという問題がある。この構成における電磁波シールドの効果は、中空部20の間隔に左右されるものであると推察されるが、この中空部20の間隔を狭くし過ぎるとちょっとしたずれによって電磁波シールド材料が接触して摩擦が生じてしまうし、中空部20の間隔を広くし過ぎるとシールド効果が薄れてしまうため、中空部20の間隔の調整が難しいという問題がある。   According to the electromagnetic shielding sliding door described in Patent Document 1, the electromagnetic shielding material does not come into contact even when the door is closed even during sliding, and the above-mentioned problem due to friction can be solved. However, even when the door is closed, there is a problem that the shielding is incomplete because the electromagnetic shielding material is non-contact. The effect of the electromagnetic wave shield in this configuration is presumed to be influenced by the interval between the hollow portions 20, but if the interval between the hollow portions 20 is too narrow, the electromagnetic wave shielding material comes into contact with a slight deviation and causes friction. If the distance between the hollow portions 20 is too wide, the shielding effect will be reduced, so that there is a problem that it is difficult to adjust the distance between the hollow portions 20.

また、通常、引き戸を取付ける場合には、レール支持枠15の上部に滑車13が通る隙間が設けてあり、引き戸本体10全体を鉛直方向に持ち上げて前記隙間部分に滑車13を通してレール部16上に滑車を乗せて取付けを行う。しかし、この特許文献1における電磁波遮蔽引き戸の場合には、鴨居部分ではF字形部材19の2つの羽根部19a、19bの間の非常に狭い中空部分にL字形部材18の羽根部18aが非接触で入り込まなければならず、また、敷居部分では逆T字形状部材27の水平板部27bがL字形状部材28によって作られる部屋の中に入るように配置されなければならないため、引き戸本体10全体を垂直方向に移動させる空間的な余裕はない。よって、この特許文献1に記載の電磁波遮蔽引き戸は、上述の通常の取付け方法では取付けることができず、また、一度取付けた後に取外すことが不可能か又は困難であるという問題がある。   Normally, when the sliding door is attached, a clearance through which the pulley 13 passes is provided above the rail support frame 15, and the entire sliding door body 10 is lifted in the vertical direction so that the clearance 13 passes through the pulley 13 and onto the rail portion 16. Mount with a pulley. However, in the case of the electromagnetic wave shielding sliding door in Patent Document 1, the blade portion 18a of the L-shaped member 18 is not in contact with the very narrow hollow portion between the two blade portions 19a, 19b of the F-shaped member 19 in the head portion. In addition, since the horizontal plate portion 27b of the inverted T-shaped member 27 must be disposed in the room formed by the L-shaped member 28 at the sill portion, the sliding door body 10 as a whole There is no room to move the space vertically. Therefore, the electromagnetic shielding sliding door described in Patent Document 1 cannot be attached by the above-described ordinary attachment method, and there is a problem that it is impossible or difficult to remove once attached.

本発明による電磁波シールド引き戸の構成を図面に基づいて説明する。図1に示すのは、本発明の電磁波シールド引き戸を設置した様子を表した模式図であり、両開きの場合を示している。この図1において、引き戸本体31は、全面を導電性材料で覆って電磁波シールドを施したものであり、上辺に取りつけた引き戸吊り枠35の上部の少なくとも2箇所に車輪取付け枠37を設け、この車輪取付け枠37に取付けられた車輪36を無目32内に設けられたレール38上に乗せることで、引き戸本体31全体を吊り下げて設置する。この引き戸本体31の閉鎖位置におけるレール38上には、ストッパ40がそれぞれ設けられており、引き戸本体31の脱落を防止している。   The configuration of the electromagnetic shielding door according to the present invention will be described with reference to the drawings. FIG. 1 is a schematic view showing a state in which the electromagnetic wave shielding sliding door of the present invention is installed, and shows a case of double opening. In FIG. 1, the sliding door main body 31 is covered with an electroconductive material and covered with an electromagnetic wave shield. Wheel mounting frames 37 are provided at at least two locations on the upper side of the sliding door hanging frame 35 attached to the upper side. The entire sliding door body 31 is suspended and installed by placing the wheel 36 attached to the wheel attachment frame 37 on a rail 38 provided in the mesh 32. Stoppers 40 are respectively provided on the rails 38 at the closed position of the sliding door main body 31 to prevent the sliding door main body 31 from falling off.

本発明による電磁波シールド引き戸は、自動ドア又は手動ドアのどちらであっても構成できるものであり、各図において自動ドアとしての構成部分と手動ドアとしての構成部分を併記している場合があるが、実際には一方のみの構成であってもよく、また、両者を採用した構成であってもよい。   The electromagnetic shielding sliding door according to the present invention can be configured with either an automatic door or a manual door, and in each drawing, there are cases where a component as an automatic door and a component as a manual door are written together. In practice, only one of the configurations may be employed, or a configuration employing both may be employed.

図1においては、自動ドアとして構成する場合の動力部分について図示している。この動力部分は、戸袋33の壁面内に設けられており、モータ、可変速機及び制御回路からなる駆動装置42によって歯車43を回転させ、これによってチェーン46を介して歯車44が回転し、チェーン47を介して歯車45が回転する。一方、引き戸本体31の側面中央部分には連結部材48が設けてあり、この連結部材48の締結部49においてチェーン47に接続する。これにより、駆動装置42によって歯車43を回転させると引き戸本体31全体がチェーン47によって引っ張られて移動する構成となっている。また、図3及び図4に示すように、戸袋枠61部分に自動ドアのセンサーとして用いるビームスイッチ62を設けて、人の出入りを検知して開閉動作を制御する。
なお、この戸袋33部分には、窓50を設けている。この場合の窓50には、電磁波シールドガラスを使用することが望ましい。
In FIG. 1, the power part in the case of configuring as an automatic door is illustrated. This power portion is provided in the wall surface of the door pocket 33, and a gear 43 is rotated by a driving device 42 including a motor, a variable speed machine, and a control circuit. As a result, the gear 44 is rotated via a chain 46. The gear 45 rotates via 47. On the other hand, a connecting member 48 is provided at the center of the side surface of the sliding door main body 31, and is connected to the chain 47 at a fastening portion 49 of the connecting member 48. Thus, when the gear 43 is rotated by the driving device 42, the entire sliding door body 31 is pulled by the chain 47 and moved. Further, as shown in FIGS. 3 and 4, a beam switch 62 used as a sensor for an automatic door is provided in the door pocket frame 61 to detect opening / closing of a person and to control the opening / closing operation.
A window 50 is provided in the door pocket 33 portion. In this case, it is desirable to use electromagnetic wave shielding glass for the window 50.

図1及び図3においては、手動ドアとして構成する場合の開閉動作に用いる引き手棒51部分について図示している。この引き手棒51は、引き戸の召し合わせ部分において一方の引き戸本体31に支点52によって回動可能に取付けられている。また、他方の引き戸本体31側には、引き手棒51の他方端が当接する当接部材53が設けられている。このような構成において引き戸が閉じられているときには、引き手棒51を引き上げることで支点52を介して他方端が当接部材53に接して、引き戸本体31が開く方向に力が加わり、これによって引き戸を容易に開くことが可能となる。なお、後述するように、本発明の電磁波シールド引き戸は閉じた状態で引き戸本体31の車輪36がレール38の凹部39に沈み込む構成となっているため、この沈み込んだ状態から手動で復帰させるときに容易に力を加えられる点で、この引き手棒51部分の構成は特に有効である。   In FIG.1 and FIG.3, the handle bar 51 part used for the opening / closing operation | movement in the case of comprising as a manual door is shown in figure. The pulling bar 51 is rotatably attached to one sliding door main body 31 by a fulcrum 52 at the summing portion of the sliding door. A contact member 53 with which the other end of the pull bar 51 contacts is provided on the other sliding door body 31 side. In such a configuration, when the sliding door is closed, the pulling bar 51 is pulled up so that the other end comes into contact with the contact member 53 via the fulcrum 52 and a force is applied in the direction in which the sliding door main body 31 is opened. The sliding door can be easily opened. As will be described later, since the electromagnetic shielding sliding door of the present invention is configured so that the wheel 36 of the sliding door main body 31 sinks into the recess 39 of the rail 38 in the closed state, the electromagnetic shield sliding door is manually returned from the depressed state. This configuration of the puller bar 51 portion is particularly effective in that a force can be easily applied sometimes.

このような本発明の電磁波シールド引き戸を採用する必要のある電磁波シールドルームにおいては、無目32、戸袋33及び床面34にそれぞれ電磁波シールド処理を施し、室内においても天井、壁面及び床面において電磁波シールド処理を施す必要がある。そして、引き戸本体31を閉じた場合における、無目32(鴨居部分)、戸袋33、床面34(敷居部分)及び他方の引き戸本体31の側面部と一方の引き戸本体31とのそれぞれの境界における電磁波シールド処理が特に重要であり、本発明はこれらの境界部分での電磁波シールド処理に特徴を有するものである。以下、図面を用いて詳細に説明を行う。   In the electromagnetic shielding room where it is necessary to employ the electromagnetic shielding sliding door of the present invention, electromagnetic shielding treatment is applied to the invisible 32, the door pocket 33, and the floor surface 34, respectively, so that electromagnetic waves are applied to the ceiling, wall surface, and floor surface in the room. Shield processing needs to be applied. And in the case where the sliding door main body 31 is closed, at the boundary between the side 32 of the seamless door body 31 and the side surface portion of the other sliding door main body 31 and the sliding door main body 31. The electromagnetic wave shielding treatment is particularly important, and the present invention is characterized by the electromagnetic wave shielding treatment at these boundary portions. Hereinafter, a detailed description will be given with reference to the drawings.

図2に示すのは、引き戸本体31を吊り下げるレール38部分の詳細な構成を表したものである。前述の通り、引き戸本体31は、上辺に取りつけた引き戸吊り枠35の上部の少なくとも2箇所に車輪取付け枠37を設け、この車輪取付け枠37に取付けられた車輪36を無目32内に設けられたレール38上に乗せることで、引き戸本体31全体を吊り下げて設置しているが、ここで、レール38上の少なくとも2箇所(車輪36と同数)には、車輪36が沈み込む凹部39が形成されている。この凹部39は、引き戸本体31を閉じて車輪取付け枠37がストッパ40に接触する位置で車輪36が沈み込むようにして位置決めを行うものであり、2つの凹部39間の距離Dが2つの車輪36の軸間の距離と同じとなるように構成する。   FIG. 2 shows a detailed configuration of a rail 38 portion for suspending the sliding door main body 31. As described above, the sliding door main body 31 is provided with the wheel mounting frames 37 at least two places on the upper part of the sliding door suspension frame 35 attached to the upper side, and the wheels 36 attached to the wheel mounting frames 37 are provided in the mesh 32. The entire sliding door body 31 is suspended by being placed on the rail 38. Here, at least two places (the same number as the wheels 36) on the rail 38 are provided with recesses 39 into which the wheels 36 sink. Is formed. The recessed portion 39 is positioned so that the wheel 36 sinks at a position where the sliding door main body 31 is closed and the wheel mounting frame 37 contacts the stopper 40, and the distance D between the two recessed portions 39 is the distance between the two wheels 36. It is configured to be the same as the distance between the axes.

図3に示すのは、引き戸本体31を閉めた場合の横方向の断面図を表したものである。この図3において、引き戸本体31は戸袋33から引出されて閉じた状態となっており、他方側の引き戸本体31と接合している。このとき一方の引き戸本体31の接合面には凹溝54が形成してあり、他方の引き戸本体31の接合面には凸部55が形成してあり、閉じたときにこれらが召し合わされる構成となっている。また、さらに前記凹溝54の内側には導電性接触片58が設けてあり、凸部55の中央部には電磁シールド材取付溝57が設けられてその内側に円弧状に形成された2つの電磁シールド材56が設けられており、引き戸本体31が召し合わされたときに導電性接触片58が2つの電磁シールド材56の間に挿入されて接触する構成となっている。この召し合わせ部分における導電性接触片58及び電磁シールド材56は、引き戸本体31の高さ方向にわたって途切れることなく設置されている。これによって、各引き戸本体31の表面に施された電磁波シールドがこの召し合わせ部分においても途切れることなく電磁シールドが行われる。   FIG. 3 shows a cross-sectional view in the horizontal direction when the sliding door body 31 is closed. In FIG. 3, the sliding door main body 31 is pulled out from the door pocket 33 and is in a closed state, and is joined to the other sliding door main body 31. At this time, a concave groove 54 is formed on the joint surface of one sliding door main body 31, and a convex portion 55 is formed on the joint surface of the other sliding door main body 31, and these are summed when closed. It has become. Further, a conductive contact piece 58 is provided inside the concave groove 54, and an electromagnetic shield material mounting groove 57 is provided in the central portion of the convex portion 55. The electromagnetic shield material 56 is provided, and when the sliding door main body 31 is summoned, the conductive contact piece 58 is inserted between the two electromagnetic shield materials 56 and comes into contact therewith. The conductive contact piece 58 and the electromagnetic shielding material 56 in the summing portion are installed without interruption over the height direction of the sliding door body 31. As a result, the electromagnetic shield is applied to the surface of each sliding door main body 31 without interruption even at the summing portion.

また、図3において、戸袋33部分における引き戸本体31と室内柱60との間においても、電磁波シールドが施されている。引き戸本体31の側面部には導電性接触片58が接続され、この導電性接触片58の先端は引き戸を閉じる際の移動方向に向かって直角に折れ曲がった形状となっている。これに対して、室内柱60側には、導電性材料で形成されたシールド材取付枠59が接続されており、導電性接触片58と対応する位置に電磁シールド材取付溝57が設けられ、その内側に円弧状に形成された2つの電磁シールド材56が設けられている。この状態で、引き戸本体31が召し合わされたときに導電性接触片58が2つの電磁シールド材56の間に挿入されて接触する構成となっている。この戸袋33部分における導電性接触片58及び電磁シールド材56は、引き戸本体31の高さ方向にわたって途切れることなく設置されている。これによって、引き戸本体31の表面に施された電磁波シールドと室内柱60の表面に施された電磁波シールドとが戸袋33部分で途切れることなくシールドされる。   In FIG. 3, an electromagnetic wave shield is also provided between the sliding door main body 31 and the indoor pillar 60 in the door pocket 33 portion. A conductive contact piece 58 is connected to the side surface of the sliding door main body 31, and the tip of the conductive contact piece 58 is bent at a right angle toward the moving direction when the sliding door is closed. On the other hand, a shield material mounting frame 59 formed of a conductive material is connected to the indoor pillar 60 side, and an electromagnetic shield material mounting groove 57 is provided at a position corresponding to the conductive contact piece 58. Two electromagnetic shielding materials 56 formed in an arc shape are provided inside thereof. In this state, when the sliding door main body 31 is summoned, the conductive contact piece 58 is inserted between the two electromagnetic shield members 56 to come into contact with each other. The conductive contact piece 58 and the electromagnetic shielding material 56 in the door pocket 33 portion are installed without interruption over the height direction of the sliding door body 31. As a result, the electromagnetic wave shield applied to the surface of the sliding door main body 31 and the electromagnetic wave shield applied to the surface of the indoor pillar 60 are shielded without interruption at the door pocket 33 portion.

ここで、前記電磁シールド材56の詳細な構成を図7(a)に示す。この電磁シールド材56は、取付板部74によって電磁シールド材取付溝57内に取付けられるものであり、逆樋状に湾曲させて形成された湾曲接触部73によって導電性接触片58と接触する。また、一定間隔で短手方向に切溝75が設けられているため、湾曲接触部73に弾性が生じ、導電性接触片58と接触した際に弾性によって一定圧力で確実に接触する。このとき先端摺動部76が電磁シールド材取付溝57の壁面に接触したまま摺動して逃げる構成となっている。   Here, the detailed structure of the electromagnetic shielding material 56 is shown in FIG. The electromagnetic shield material 56 is attached in the electromagnetic shield material attachment groove 57 by the attachment plate portion 74, and comes into contact with the conductive contact piece 58 by a curved contact portion 73 formed by bending in a reverse bowl shape. In addition, since the kerf 75 is provided in the short direction at regular intervals, the curved contact portion 73 is elastic, and when it comes into contact with the conductive contact piece 58, it comes into contact with certain pressure with elasticity. At this time, the tip sliding portion 76 slides and escapes while being in contact with the wall surface of the electromagnetic shield material mounting groove 57.

図4に示すのは、引き戸本体31を閉め切っていない状態における縦方向の断面図を表したものである。この図4に示すように、引き戸本体31は上部の引き戸吊り枠35に車輪取付枠68(37)が接続され、この車輪取付枠68に軸67によって車輪66(36)が取付けられる。一方、無目蓋64で覆われた無目32部分の鴨居横柱65の上部にレール支持枠70が接続され、このレール支持枠70にレール38が接続される。このレール38に前記車輪66を乗せるようにして引き戸本体31全体が吊り下げられて設置される。また、レール38の下側に接触して振れ止めを行うために振れ止めローラ69を設けてもよい。   FIG. 4 shows a longitudinal sectional view in a state where the sliding door main body 31 is not closed. As shown in FIG. 4, in the sliding door main body 31, a wheel mounting frame 68 (37) is connected to the upper sliding door suspension frame 35, and a wheel 66 (36) is mounted to the wheel mounting frame 68 by a shaft 67. On the other hand, a rail support frame 70 is connected to an upper portion of the Kamoi horizontal column 65 of the seamless 32 portion covered with the seamless cover 64, and the rail 38 is connected to the rail support frame 70. The entire sliding door body 31 is suspended and installed so that the wheel 66 is placed on the rail 38. Further, an anti-sway roller 69 may be provided to make contact with the lower side of the rail 38 and perform anti-sway.

この図4において、引き戸本体31と室内側の鴨居横柱65との間に隙間が生じてしまうので、この隙間部分において電磁シールドを施す必要がある。そこで、引き戸本体31の室内側の上辺部分に導電性接触片58が接続され、この導電性接触片58の先端は鉛直下方に向かって直角に折れ曲がった形状となっている。これに対して、室内側の鴨居横柱65には、導電性材料で形成されたシールド材取付枠59が接続されており、導電性接触片58と対応する位置に電磁シールド材取付溝57が設けられ、その内側に円弧状に形成された2つの電磁シールド材56が設けられている。これらの導電性接触片58及び電磁シールド材56は、引き戸本体31が開かれている場合には非接触状態にあり、引き戸本体31が閉じられて召し合わされたときに、前記レール38上の凹部39に車輪66(36)が沈み込むことによって、導電性接触片58が2つの電磁シールド材56の間に挿入されて接触する構成となっている。この戸袋33部分における導電性接触片58及び電磁シールド材56は、引き戸本体31の横幅方向にわたって途切れることなく設置されている。これによって、引き戸本体31の表面に施された電磁波シールドと鴨居横柱65の表面に施された電磁波シールドとが鴨居部分で途切れることなくシールドされる。   In FIG. 4, a gap is generated between the sliding door main body 31 and the indoor side horizontal column 65, and it is necessary to provide an electromagnetic shield in this gap portion. Therefore, the conductive contact piece 58 is connected to the indoor side upper side portion of the sliding door body 31, and the tip of the conductive contact piece 58 is bent at a right angle vertically downward. On the other hand, a shield material mounting frame 59 formed of a conductive material is connected to the indoor side column 65, and an electromagnetic shield material mounting groove 57 is formed at a position corresponding to the conductive contact piece 58. Two electromagnetic shielding materials 56 formed in an arc shape are provided inside thereof. The conductive contact piece 58 and the electromagnetic shielding material 56 are in a non-contact state when the sliding door main body 31 is opened, and are recessed on the rail 38 when the sliding door main body 31 is closed and summoned. When the wheel 66 (36) sinks into 39, the conductive contact piece 58 is inserted between the two electromagnetic shield members 56 to come into contact with each other. The conductive contact piece 58 and the electromagnetic shielding material 56 in the door pocket 33 portion are installed without interruption over the lateral width direction of the sliding door main body 31. Thereby, the electromagnetic wave shield provided on the surface of the sliding door main body 31 and the electromagnetic wave shield provided on the surface of the Kamoi horizontal pillar 65 are shielded without interruption at the Kamoi portion.

また、図4において、引き戸本体31と床面34(敷居部分)との間に隙間が生じてしまうので、この隙間部分において電磁シールドを施す必要がある。そこで、引き戸本体31の下辺部分の室内側と室外側のそれぞれに図7(b)に示すような円弧状の凸部が下面に向いて形成された電磁シールド材71を設ける。これに対して、床面34の敷居部分には導電性床部材41を設ける。これらの電磁シールド材71及び導電性床部材41は、引き戸本体31が開かれている場合には非接触状態にあり、引き戸本体31が閉じられて召し合わされたときに、前記レール38上の凹部39に車輪66(36)が沈み込むことによって、電磁シールド材71が導電性床部材41に接触する構成となっている。この敷居部分における電磁シールド材71及び導電性床部材41は、引き戸本体31の横幅方向にわたって途切れることなく設置されている。これによって、引き戸本体31の表面に施された電磁波シールドと床面34に施された電磁波シールドとが敷居部分で途切れることなくシールドされる。   Moreover, in FIG. 4, since a clearance gap will arise between the sliding door main body 31 and the floor surface 34 (sill part), it is necessary to give an electromagnetic shield in this clearance gap part. In view of this, an electromagnetic shielding material 71 is provided on each of the indoor side and the outdoor side of the lower side portion of the sliding door main body 31, as shown in FIG. On the other hand, the conductive floor member 41 is provided on the sill portion of the floor surface 34. The electromagnetic shielding material 71 and the conductive floor member 41 are in a non-contact state when the sliding door main body 31 is opened, and when the sliding door main body 31 is closed and summoned, the recesses on the rail 38 are provided. When the wheel 66 (36) sinks into 39, the electromagnetic shielding material 71 comes into contact with the conductive floor member 41. The electromagnetic shielding material 71 and the conductive floor member 41 in the sill portion are installed without interruption over the width direction of the sliding door body 31. Thereby, the electromagnetic wave shield applied to the surface of the sliding door main body 31 and the electromagnetic wave shield applied to the floor surface 34 are shielded without interruption at the sill portion.

ここで、前記電磁シールド材71の詳細な構成を図7(b)に示す。この電磁シールド材71は、取付板部74によって引き戸本体31の壁面に取付けられるものであり、逆樋状に湾曲させて形成された湾曲接触部73によって導電性床部材41と接触する。また、一定間隔で短手方向に切溝75が設けられているため、湾曲接触部73に弾性が生じ、導電性床部材41と接触した際に弾性によって一定圧力で確実に接触する。このとき先端摺動部76は、図示のように非接触で弾性によって逃げる構成としてもよいし、引き戸本体31の底面に接触したまま摺動して逃げる構成としてもよい。   Here, the detailed structure of the electromagnetic shielding material 71 is shown in FIG. The electromagnetic shielding material 71 is attached to the wall surface of the sliding door main body 31 by the attachment plate portion 74, and comes into contact with the conductive floor member 41 by a curved contact portion 73 formed by bending in a reverse bowl shape. In addition, since the kerf 75 is provided in the short direction at regular intervals, the curved contact portion 73 is elastic, and when it comes into contact with the conductive floor member 41, it comes into contact with certain pressure with elasticity. At this time, the tip sliding portion 76 may be configured to escape by elasticity without contact as illustrated, or may be configured to slide and escape while being in contact with the bottom surface of the sliding door body 31.

なお、図4に示すように、導電性床部材41の一部に振れ止め車63を設けるとともに、引き戸本体31の底面にガイド溝72を設けて、振れ止め車63がガイド溝72内に配置されるようにして引き戸本体31を設置することによって、引き戸本体31の開閉動作時に引き戸が振れるのを防ぐようにしている。   As shown in FIG. 4, the steadying wheel 63 is provided on a part of the conductive floor member 41, and the guide groove 72 is provided on the bottom surface of the sliding door body 31, and the steadying wheel 63 is disposed in the guide groove 72. By installing the sliding door body 31 as described above, the sliding door is prevented from swinging when the sliding door body 31 is opened and closed.

図5に示すのは、本発明による電磁波シールド引き戸を設置する場合に、戸袋との境界部分及び鴨居部分の開口部分に電磁波シールド処理を施した様子を表した斜視図である。前述のように、戸袋との境界部分である室内柱60にはシールド材取付枠59が高さ方向にわたって途切れることなく設けられ、このシールド材取付枠59の電磁シールド材取付溝57内に電磁シールド材56が湾曲接触部73を対峙させた状態で設置される。同様に、鴨居部分においても鴨居横柱65にシールド材取付枠59が水平方向にわたって途切れることなく設けられ、このシールド材取付枠59の電磁シールド材取付溝57内に電磁シールド材56が湾曲接触部73を対峙させた状態で設置される。室内柱60と鴨居横柱65が交わる角部分においてはシールド材取付枠59が繋がって連続するように構成してシールド漏れがないようにする。また、この図5は両開きタイプの引き戸の例として記載しており、左右の引き戸で鴨居部分に設けたシールド材取付枠59での電磁シールド材56の設置位置をずらし、召し合わせ部分で一部重合するように構成している。   FIG. 5 is a perspective view showing a state in which an electromagnetic wave shielding process is performed on a boundary part with a door pocket and an opening part of a duck part when an electromagnetic wave shielding sliding door according to the present invention is installed. As described above, the shielding material mounting frame 59 is provided in the height direction in the indoor column 60 which is a boundary portion with the door pocket, and the electromagnetic shielding material 57 is provided in the electromagnetic shielding material mounting groove 57 of the shielding material mounting frame 59. The material 56 is installed in a state where the curved contact portion 73 is opposed. Similarly, the shield material attachment frame 59 is provided on the horizontal column 65 without any interruption in the horizontal direction at the head portion, and the electromagnetic shield material 56 is curved in the electromagnetic shield material attachment groove 57 of the shield material attachment frame 59. It is installed with 73 facing each other. In the corner portion where the indoor pillar 60 and the Kamoi horizontal pillar 65 cross each other, the shield material mounting frame 59 is connected to be continuous so that there is no shield leakage. Further, FIG. 5 is described as an example of a double-sliding type sliding door, and the installation position of the electromagnetic shielding material 56 in the shielding material mounting frame 59 provided in the duck portion is shifted by the left and right sliding doors, and a part of the summing portion is shown. It is configured to polymerize.

図6に示すのは、両開きタイプの引き戸の例として、左右の引き戸本体31の各4隅の構造を説明するための斜視図である。この図6から分かるように、左右の各引き戸本体31の上辺部及び戸袋に面した側辺部には、先端が折り曲げられた導電性接触片58が途切れることなく設けてあり、この導電性接触片58が、図5における戸袋との境界部分及び鴨居部分に対して設けたシールド材取付枠59での電磁シールド材56に接触することとなる。
また、2つの引き戸本体31の召し合わせ部分は、一方に凹溝54を他方に凸部55を設け、この凹溝54内に導電性接触片58を設けるとともに凸部55の先端に電磁シールド材取付溝57を設けてそこに電磁シールド材56を設置することで、2つの引き戸が召し合わされた時に導電性接触片58が電磁シールド材56の間に入って接触して電磁シールドがなされる。
底面部分には、床面に形成した導電性床部材41と接触して電磁シールドを形成する電磁シールド材71が横幅方向にわたって途切れることなく形成されており、また、振れ止め車63が摺動するためのガイド溝72が設けてある。
FIG. 6 is a perspective view for explaining the structure of each of the four corners of the left and right sliding door bodies 31 as an example of a double-opening type sliding door. As can be seen from FIG. 6, conductive contact pieces 58 whose front ends are bent are provided without interruption on the upper side of each sliding door main body 31 and the side part facing the door pocket. The piece 58 comes into contact with the electromagnetic shielding material 56 in the shielding material mounting frame 59 provided for the boundary portion with the door pocket and the duck portion in FIG.
In addition, the summing portion of the two sliding door main bodies 31 has a concave groove 54 on one side and a convex portion 55 on the other side, and a conductive contact piece 58 is provided in the concave groove 54 and an electromagnetic shielding material is provided at the tip of the convex portion 55. By providing the mounting groove 57 and installing the electromagnetic shielding material 56 there, when the two sliding doors are summoned, the conductive contact piece 58 enters between the electromagnetic shielding material 56 and comes into contact with the electromagnetic shielding material.
An electromagnetic shielding material 71 that forms an electromagnetic shield in contact with the conductive floor member 41 formed on the floor surface is formed on the bottom surface without interruption in the width direction, and the steadying wheel 63 slides. A guide groove 72 is provided.

以上のような構成の電磁波シールド引き戸の動作について説明する。先ず、引き戸本体31が開いているときには、引き戸本体31はレール38上に車輪66を乗せた状態で引き戸本体31全体が吊り下げられて設置されており、この状態においては、鴨居部分の導電性接触片58は鴨居横柱65に取付けられたシールド材取付枠59の電磁シールド材56に接触しておらず、敷居部分の電磁シールド材71は導電性床部材41に接触しておらず、また、戸袋33との境界部分においても導電性接触片58は電磁シールド材56と接触していない。よって、引き戸本体31が開いている状態においては、電磁シールドに用いる部材が対応する導電性接触片に接触することはなく、電磁シールドもなされていない。   The operation of the electromagnetic shielding door having the above configuration will be described. First, when the sliding door body 31 is open, the sliding door body 31 is installed with the entire sliding door body 31 suspended while the wheels 66 are placed on the rails 38. The contact piece 58 is not in contact with the electromagnetic shield material 56 of the shield material mounting frame 59 attached to the Kamoi horizontal column 65, the electromagnetic shield material 71 of the sill portion is not in contact with the conductive floor member 41, and The conductive contact piece 58 is not in contact with the electromagnetic shield material 56 even at the boundary portion with the door pocket 33. Therefore, in the state where the sliding door main body 31 is open, the member used for the electromagnetic shield does not come into contact with the corresponding conductive contact piece, and the electromagnetic shield is not made.

次に、引き戸本体31を閉じるときには、駆動装置42を駆動させて歯車43を回転させ、これによってチェーン46、歯車44、チェーン47、歯車45をそれぞれ介して、引き戸本体31の側面中央部分に設けられた連結部材48の締結部49に対してチェーン47によって動力を伝達して、引き戸本体31を閉じる。このとき、引き戸本体31は車輪66がレール38上を転がることで移動するが、この閉じる過程においても電磁シールドに用いる各部材が対応する導電性接触片に接触することはない。そして、引き戸本体31を完全に閉じる位置までスライドさせると、車輪66がレール38上の凹部39部分に沈み込み、2つの引き戸本体31が召し合わされる。このように、車輪66がレール38上の凹部39部分に沈み込むことによって、引き戸本体31全体が凹部39の深さの分だけ鉛直下方に移動することとなり、この結果、鴨居部分の導電性接触片58は鴨居横柱65に取付けられたシールド材取付枠59の電磁シールド材56に接触し、敷居部分の電磁シールド材71は導電性床部材41に接触し、また、戸袋33との境界部分においても導電性接触片58が電磁シールド材56と接触する。さらに、2つの引き戸本体31が召し合わせ部分においても、一方の引き戸本体31に設けられた導電性接触片58が、他方の引き戸本体31に設けられた電磁シールド材56に接触する。よって、引き戸本体31を完全に閉じられたときには、鴨居部分、敷居部分、戸袋33との境界部分及び2つの引き戸本体31が召し合わせ部分の全てにおいて電磁シールドが施されることとなり、シールド漏れが生じることがない。   Next, when the sliding door main body 31 is closed, the driving device 42 is driven to rotate the gear 43, thereby providing the central portion of the side surface of the sliding door main body 31 through the chain 46, the gear 44, the chain 47, and the gear 45. Power is transmitted by the chain 47 to the fastening portion 49 of the connecting member 48 thus closed, and the sliding door body 31 is closed. At this time, the sliding door main body 31 moves as the wheel 66 rolls on the rail 38, but each member used for the electromagnetic shield does not contact the corresponding conductive contact piece even in the closing process. When the sliding door body 31 is slid to the fully closed position, the wheel 66 sinks into the concave portion 39 on the rail 38, and the two sliding door bodies 31 are summoned. Thus, when the wheel 66 sinks into the concave portion 39 on the rail 38, the entire sliding door body 31 moves vertically downward by the depth of the concave portion 39. As a result, the conductive contact of the duck portion is achieved. The piece 58 contacts the electromagnetic shielding material 56 of the shielding material mounting frame 59 attached to the Kamoi horizontal column 65, the electromagnetic shielding material 71 of the sill portion contacts the conductive floor member 41, and the boundary portion with the door pocket 33. The conductive contact piece 58 is also in contact with the electromagnetic shield material 56 in FIG. Further, even at the portion where the two sliding door main bodies 31 are summoned, the conductive contact piece 58 provided on one sliding door main body 31 contacts the electromagnetic shield material 56 provided on the other sliding door main body 31. Therefore, when the sliding door main body 31 is completely closed, the electromagnetic shield is applied to all of the summit portion, the sill portion, the boundary portion between the door pocket 33 and the two sliding door main bodies 31 and the shield leakage. It does not occur.

以上のように、引き戸本体31が開いているとき及びスライド動作中には、電磁シールドに用いる部材が対応する導電性接触片に接触することがないため、摩擦や引っ掛かりによって電磁シールド部材が損傷することがなく、引き戸本体31を閉じたときに電磁シールドに用いる部材が対応する導電性接触片に接触して、鴨居部分、敷居部分、戸袋33との境界部分及び2つの引き戸本体31が召し合わせ部分の全てにおいて電磁シールドが施される。   As described above, when the sliding door body 31 is open and during the sliding operation, the member used for the electromagnetic shield does not come into contact with the corresponding conductive contact piece, so that the electromagnetic shielding member is damaged by friction or catching. When the sliding door body 31 is closed, the member used for the electromagnetic shield comes into contact with the corresponding conductive contact piece, and the duck portion, the sill portion, the boundary portion with the door pocket 33 and the two sliding door bodies 31 are summoned. All parts are electromagnetically shielded.

前記実施例においては、2つの引き戸本体31を用いて両開きタイプとして構成した場合を例として説明を行ったが、本発明はこれに限られるものではなく、片開きタイプとして構成した場合にも採用することができるものである。この場合には、例えば、前記実施例1において2つの引き戸本体31の召し合わせ部分に採用した構成を1つの引き戸本体31と室内柱60との境界に適用することで、片開きタイプにおいても同様に構成することが可能となる。   In the said Example, although demonstrated as an example the case where it comprised as a double-opening type using the two sliding door main bodies 31, this invention is not restricted to this, It employ | adopts also when comprised as a single-opening type. Is something that can be done. In this case, for example, by applying the configuration adopted in the summing portion of the two sliding door main bodies 31 in the first embodiment to the boundary between the single sliding door main body 31 and the indoor pillar 60, the same applies to the single-open type. It becomes possible to comprise.

また、前記実施例においては、自動ドアとして構成した例として、図1に示すように、戸袋33の壁面内に駆動装置42等を設けて構成していたが、本発明はこれに限られず、手動ドアであってもよい。この場合には、凹部39に車輪36がはまることによって全体が落ち込んだ引き戸本体31をレール38上に持ち上げるときに、引き手棒51が使用されることになる。   Moreover, in the said Example, as shown in FIG. 1 as an example comprised as an automatic door, although it comprised, providing the drive device 42 etc. in the wall surface of the door pocket 33, this invention is not limited to this, It may be a manual door. In this case, the pulling bar 51 is used when the sliding door main body 31 that has fallen down as a result of the wheel 36 being fitted in the recess 39 is lifted onto the rail 38.
