Description

【０００１】
【発明の属する技術分野】
本発明は、引戸装置に関し、詳しくは一方の扉を他方の扉に収納可能に構成した２重の引戸装置の改良に関するものである。
【０００２】
【従来の技術】
従来の前方の前扉を後方の後扉内に収納可能に構成した２重の引戸装置は、戸袋の幅を縮小し、引戸装置全体の小型化を計ることを目的として、図１６に示すような、引戸を前後に区分し、前扉は後方の扉内に収納可能とした壁収納型引戸装置を挙げることができる（特許文献１参照）。
【０００３】
図において壁収納型引戸装置５０は、引戸枠部材５１と、該枠部材５１の一側に形成された戸袋５２内に収納される引戸５３とより構成される。引戸５３は、閉じ側の前扉５３ａと、収納側の後扉５３ｂとより構成される。また引戸枠部材５１の上枠５１ａ内には引戸走行用レール５４を収納する。このレール５４は周知の如く、引戸５３が自重により閉塞位置に移行する如く、若干傾斜して取り付けられる。
【０００４】
なお、後扉５３ｂは、前扉５３ａを収納すべく前側を開口した構造とし、かつ上方内部には前扉支持用レール５５を取り付ける。前扉５３ａは対をなす前後の吊り車５６ａ、５６ｂの内、前部吊り車５６ａは引戸走行用レール５４に、また後部吊り車５６ｂは上記前扉支持用レール５５に支持せしめる。ただし後扉５３ｂの吊り車５７は、前後共、引戸走行用レール５４に支持せしめる。
【０００５】
また前後の両扉５３ａ、５３ｂには共通の連動扞６０を備える。この連動扞６０は、その基端６１ａを戸袋５２の後部下方に回動可能に取り付け、前扉５３ａの後部に形成された縦溝６２ａに挿入される摺動駒６３ａに連動扞６０の先端を取り付け、後扉５３ｂの後部に形成された縦溝６２ｂに挿入される摺動駒６３ｂを貫挿する。
【０００６】
これにより閉塞位置にある前扉５３ａを手動により開放位置に移行するときは、連動扞６０を介して後扉５３ｂを追随して移行させる。
【０００７】
ついで引戸を引き出すときは、前扉を引き出すことにより、前扉５３ａの前進に伴い、連動扞６０は基端６１ａを基準として回動し摺動駒６３ｂを介して後扉５３ｂを追随して引き出す。
【０００８】
この場合、引戸収納用戸袋は、従来構造と比べて小型とすることができる効果がある。しかし、該引戸装置においては、前扉の後部吊り車は、後扉の吊り車との干渉を避けるため、引戸走行用レールとは別に設けた前扉の後部吊り車支持用レールとする必要があり、後扉の走行には問題は生じないものの、前扉の走行に関しては、２本のレールの平行度、前後の吊り車の高低差等の狂いによって引戸の開閉がスムーズに行われない場合があるとともに、２本のレールに前後の引き戸を載置する必要からその取付作業に手数を要するもので、かかる問題点を解消した伸縮引戸として、図１７に示す引戸装置７０がある（特許文献２参照）。
【０００９】
この引戸装置７０は、間隔をあけて平行に配置された板材７４、７４の上端及び下端のコーナー部分で連結板７５、７５により連結され第１扉７１を構成し、各板材７４、７４の間に、第１扉７１と同様に平行に配置された板材７６、７６又は一枚物の板材を配設し、図示の如く連結板７７、７７を取り付ける。
７３は、連結板７５、７５、７７、７７に取り付けられたローラ等の走行体を示し、レール７８内を走行するように構成する。

【発明が解決しようとする課題】
しかし、上記構成によるときは、連結板のみによる板材の連結は板面に対する垂直荷重に対し非常に弱く、外力により容易に変形し、引戸のスムーズな開閉に支障をきたす等の問題がある。
【００１２】
本発明はかかる点に鑑み、前後の扉の走行を安定させるとともに、その取付作業を容易とする他、前方の前扉を後方の後扉内に収納可能に構成した２重の引戸装置扉を提供することを目的とする。
【００１３】
【課題を解決するための手段】

また、第３の発明は、枠部材の上枠に備えた１本の引戸走行用レールに、前扉の戸車及び後扉の戸車を載置し、前扉を後扉内に収納可能に構成した２重の引戸装置扉において、後扉に形成したスリット部に、戸車を前扉の上面に取り付けるための前扉の戸車取付板を嵌入させるとともに、スリット部開放端下面と前扉上面間に滑走部材を設け、後扉の前部を前扉に摺動可能に支持することを特徴とする。
【００２０】
上記の構成からなる第３の発明は、前後の戸車によって支持される前扉の上面と後扉前方の間を滑走部材を介して摺動可能に後扉を取り付けるから両扉の組立が簡便に行うことができる。
【００２１】
また、第４の発明は、枠部材の上枠に備えた１本の引戸走行用レールに、前扉の戸車及び後扉の戸車を載置し、前扉を後扉内に収納可能に構成した２重の引戸装置扉の組立方法において、後扉に形成したスリット部の開放端から前扉の戸車取付板を嵌入させた後、前記スリット部の開放端を戸車を後扉の上面に取り付けるための後扉の戸車取付板で遮蔽することを特徴とする。
【００２２】

【００２３】
また、第５の発明は、枠部材の上枠に備えた１本の引戸走行用レールに、前扉の戸車及び後扉の戸車を載置し、前扉を後扉内に収納可能に構成した２重の引戸装置扉の組立方法において、後扉の上面の前後の戸車間に前扉の後部戸車の移動を許容するスリット部を設け、前扉の後部戸車を後扉の前後戸車の間に位置せしめ、後部扉の側面に設けた切欠部を介して前扉を後扉の側方より嵌合するようにしたことを特徴とする。
【００２４】
上記の構成からなる第５の発明は、前扉の後部戸車を後部扉の側面に設けた切欠部を介して嵌合しするから後扉の戸車も組立前から取り付けた状態で組み込むことが可能となる。
【００２５】
【発明の実施の形態】
以下、本発明の実施の形態を図に示す実施例に基づいて説明する。図１乃至図３は第１実施例を示すもので、引戸装置１は出入口に配置された引戸２と、該引戸取付枠３とを備える。引戸収納枠３は一側の戸袋４を形成し、該戸袋４は周知の引戸収納壁内に挿入される。
５は点検用蓋を示し、レールの交換やメンテナンス時、に開放し作業を行うもので、図１、２においては戸袋４とともに一点波線を以て示す。
【００２６】
引戸２は従来例（図１６）と同様に前扉２ａと後扉２ｂとより構成される。また枠部材３の上枠３ａには引戸走行用レール６を備え、前扉２ａの戸車７、７と後扉２ｂの戸車８ａ、８ｂを載置し常時図１に示す閉鎖状態に保持する場合には引戸走行用レール６を図例において若干左下がりに構成する。
この際、扉２を開放する際に任意の位置で停止させたい場合には周知のストッパ機構を用いることが好ましい。
【００２７】
次に、引戸２の組立要領を図６乃至図９に基づき説明する。
後扉２ｂは一側面を開放するとともに、上面には受け入れ用切り欠き部ｍを、前扉２ａには両側面上部に進入用切り欠き部ｎを設け、図６に示すように前扉２ａには戸車７、７を後扉２ｂには後方の戸車８ｂを取り付けた状態で前扉２ａを後扉２ｂの開放された側面から進入せしめ、受け入れ用切り欠き部ｍを越え後扉２ｂの上面において前扉２ａに形成した進入用切り欠き部ｎが入り込む様、図７に示す形状に組み合わせる。
【００２８】
次いで、図８に示すように後扉２ｂ前方の戸車８ａを備えるコ字状のフランジｆを前扉２ａをまたぐようにして後扉２ｂ前方に取り付ける。
取付に際してはボルト締め等、強固に固着することのできる固着手段を採用することが好ましい。
【００２９】
この状態で、図９に示すように前扉２ａを移行せしめても前扉２ａの進行は後扉２ｂ前方の戸車８ａのフランジｆによって係止され、戸車８ａの取付によって引戸２の前扉２ａが後扉２ｂから外れることはない。
【００３０】
次に、第２の発明に係る引戸２の組立要領を図１０乃至図１３に基づいて説明する。
この引戸２は、第１の発明と同様、一側面を開放した後扉２ｂの上面に開放した側面側より反対の側面近傍に取り付けられた戸車８ｂまで前扉２ａに取り付けられた戸車８、８の戸車取付板ｔ、ｔの進入を許容するスリット部ｓを形成したもので、図１０に示すように前扉２ａには戸車７、７を後扉２ｂには後方の戸車８ｂを取り付けた状態で前扉２ａを後扉２ｂの開放された側面から進入せしめ、前扉２ａに取り付けられた戸車８、８の戸車取付板ｔ、ｔをスリット部ｓに進入せしめる（図例では前扉２ａの後扉２ｂ側の戸車８のみがスリット部ｓに進入している例を示すが戸車の位置を変更又は後扉２ｂの上面を突出せしめることにより前扉２ａの戸車８両方をスリット部ｓ内に進入させるようにすることもできる）。
【００３１】
前扉２ａを後扉２ｂに進入させた状態で後扉２ｂの前方の戸車８ａを第１の発明と同様、適宜固着手段を用いて後扉２ｂに固着せしめる。
【００３２】
この状態で、第１の発明と同様、図１２に示すように前扉２ａを移行せしめても前扉２ａの進行は後扉２ｂ前方の戸車８ａのフランジｆ’によって係止され、戸車８ａの取付によって引戸２の前扉２ａが後扉２ｂから外れることはない。
【００３３】
次に図４、図５は、図２のＸ−Ｘにおける一部断面矢視図３に相当する別の実施例を示し、第１の発明における受け入れ用切り欠き部ｍと進入用切り欠き部ｎ、第２の発明におけるスリット部ｓ、更には戸車７、７、８ａ、８ｂをそれぞれの扉の下面に設けた例を示し、上枠３ｂにはガイドレール８を引戸枠３下方には戸車を載置するレール６’を備えてなる。
【００３４】
図４における戸車７’、７’、８ａ’、８ｂ’は中央を凹部とした形状で対応するレール６’は中央部に凸部を構成し、戸車７’、７’、８ａ’、８ｂ’の凹部をレール６’の凸部に載置して構成する。
【００３５】
また、図５に示す戸車７’’、７’’、８ａ’’、８ｂ’’は中央部が凸なる一般的な戸車でこれに対応するレール６’’は中央部に凹なる溝部を形成し、戸車７’’、７’’、８ａ’’、８ｂ’’を載置するように構成する。
なお、図５では戸車の保持を両側から支える構成を示したが、図４に示す片側からの支持でもよく、また図４に示す例において戸車を両側から支える様にしてもよいことはいうまでもない。
【００３６】
次に、図１５に示す第３の発明について説明する。
第３の発明の引戸装置１は、第２の発明と同様、前扉２ａに取り付けられた戸車７、７の戸車取付板ｔ、ｔをスリット部ｓに進入せしめる構造で、好ましくは前扉２ａを後扉２ｂに取り付けた後、前扉２ａが後扉２ｂから脱落することを防止するために後扉２ｂのスリット部開放端にストッパ板ＳＴを取り付けるようにしてもよい。
【００３７】
この際、後扉２ｂの前方部分は、スリット部開放端下面と前扉上面間に滑走部材Ｋを設け、前扉２ａ上面を摺動可能に取り付けるようにする。
【００３８】
滑走部材Ｋは特に限定されるものではないが、同図（Ａ）に示す、摺動性の高い材質からなる滑走体Ｋ１や同図（Ｂ）に示すようにスリット部開放端下面に取り付けるローラＲによって構成することが好ましい。
【００３９】
次いで、第５の発明に係る引戸装置の組立方法について説明する。
この組立方法は、図１４に示す如く、後扉２ｂの前方側面に、前扉２ａの後端から後部戸車７が側面より進入可能となる程度の切欠部分Ｋを形成し、後扉２ｂの上面には前後の戸車８、８間を前扉２ａの後部戸車７の移動を許容するスリット部としたもので、前扉２ａを後扉２ｂに側方より嵌合させた後、後扉２ｂの切欠部分ＹをカバーＣをもって覆うものである。
【００４０】
また、前後の扉の移行に際しては前扉２ａの移行に伴い、後扉２ｂを移行させる場合には従来例と同様、連動杆６０を取り付けるようにしてもよい。構造上、前扉２ａが全閉した後に後扉２ｂが閉まり始め全体として引戸２が全閉に、前扉２ａが全開した後に後扉２ｂが開き始めて全体として引戸２が全開となるようにする場合は連動杆を取り付ける必要はない。
【００４１】
以上、本発明の引戸装置について、その実施例に基づいて説明したが、本発明は上記実施例に記載した構成に限定されるものではなく、その趣旨を逸脱しない範囲において適宜その構成を変更することができるものである。
【００４２】
【発明の効果】
以上の如く第１の発明によるときは、出入口に配置された引戸を前後に区分し、前扉と後扉に設けた戸車を１つのレールに載置することができるから構成が簡単な上に引戸の開閉をスムーズに行えるとともに、その取付やメンテナンスが簡便かつ容易になる。
また第２、４の発明によるときは、一方も扉の上面又は下面にスリット部を構成するのみで前扉と後扉に設けた戸車を１つのレールに載置することができるから扉の加工も簡便かつ容易でその制作費を低減することができる等の効果を有する。
また第３の発明によるときは、前後の戸車によって支持される前扉の上面と後扉前方の間を滑走部材を介して摺動可能に後扉を取り付けるから両扉の組立が簡便に行うことができ、滑走部材として滑走体を前扉上面に取り付けるときは後扉に前方の戸車を取り付ける必要がない。
更に第５の発明によるときは、前扉の後部戸車を後部扉の側面に設けた切欠部を介して嵌合するから後扉の戸車も組立前から取り付けた状態で組み込むことが可能となる等の効果を有する。

BACKGROUND OF THE INVENTION
The present invention relates to a sliding door device, and more particularly to an improvement of a double sliding door device configured such that one door can be stored in the other door.
[0002]
[Prior art]
As shown in FIG. 16, the conventional double sliding door device configured such that the front front door can be stored in the rear rear door is intended to reduce the width of the door pocket and reduce the size of the entire sliding door device. In addition, a wall-sliding type sliding door device in which the sliding door is divided into front and rear and the front door can be stored in the rear door can be cited (see Patent Document 1).
[0003]
In the figure, a wall storage type sliding door device 50 includes a sliding door frame member 51 and a sliding door 53 stored in a door pocket 52 formed on one side of the frame member 51. The sliding door 53 includes a closed-side front door 53a and a storage-side rear door 53b. The sliding door running rail 54 is housed in the upper frame 51 a of the sliding door frame member 51. As is well known, the rail 54 is attached with a slight inclination so that the sliding door 53 moves to the closed position by its own weight.
[0004]
The rear door 53b has a structure in which the front side is opened to accommodate the front door 53a, and a front door support rail 55 is attached to the upper inside. The front door 53a is supported by the sliding door traveling rail 54, and the rear suspension wheel 56b is supported by the front door support rail 55, of the pair of front and rear suspension vehicles 56a and 56b. However, the suspension wheel 57 of the rear door 53b is supported by the sliding door traveling rail 54 in the front and rear.
[0005]
The front and rear doors 53a and 53b are provided with a common interlocking rod 60. The interlocking rod 60 has a base end 61a rotatably attached to the lower portion of the rear portion of the door pocket 52, and the tip of the interlocking rod 60 is attached to a sliding piece 63a inserted into a longitudinal groove 62a formed in the rear portion of the front door 53a. The sliding piece 63b inserted in the vertical groove 62b formed in the rear part of the attachment and the rear door 53b is penetrated.
[0006]
As a result, when the front door 53a in the closed position is manually shifted to the open position, the rear door 53b is moved following the interlocking rod 60.
[0007]
Next, when pulling out the sliding door, by pulling out the front door, as the front door 53a moves forward, the interlocking rod 60 rotates with respect to the base end 61a and pulls out the rear door 53b via the sliding piece 63b. .
[0008]
In this case, the sliding door storage door pocket has an effect that can be made smaller than the conventional structure. However, in the sliding door device, the rear suspension vehicle of the front door needs to be a rear suspension vehicle support rail provided separately from the sliding door traveling rail in order to avoid interference with the rear door suspension vehicle. Yes, there will be no problem in running the rear door, but when the front door is running, the sliding door cannot be opened and closed smoothly due to deviations in the parallelism of the two rails and the height difference between the front and rear suspension vehicles. In addition, since it is necessary to place the front and rear sliding doors on two rails, the mounting work requires a lot of work, and there is a sliding door device 70 shown in FIG. 2).
[0009]
This sliding door device 70 is connected by connecting plates 75, 75 at the corners of the upper and lower ends of plate members 74, 74 that are arranged in parallel at intervals to form a first door 71, and between the plate members 74, 74. Similarly to the first door 71, plate members 76, 76 arranged in parallel or a single plate member are arranged, and connecting plates 77, 77 are attached as shown.
Reference numeral 73 denotes a traveling body such as a roller attached to the connecting plates 75, 75, 77, 77, and is configured to travel in the rail 78.
