Description

本発明は、オフィスビル内やクロゼットや家具等の引戸で開閉する開口部に設置され、閉時は複数の引戸を面一に並べて見栄え良く開口部を閉止する一方、開時は引戸を引違い状態に重ねて開口部を開けるフラット引戸装置に関する。   The present invention is installed in an office building or an opening that opens and closes with a sliding door such as a closet or furniture, and when closed, a plurality of sliding doors are arranged side by side to close the opening with a good appearance, while when opened, the sliding door is moved The present invention relates to a flat sliding door device that opens an opening in a state of being overlapped.

従来、この種のフラット引戸装置では、戸車を係合させて引戸を開閉方向に案内するガイドレールの端部を湾曲し、このレールの湾曲部の案内で、一側の引戸を、閉時は他側の引戸と面一に並べて開口部を閉止する閉止位置と、開時は引違い状態に重ね合わせて開口部を開ける引違い位置とに誘導することによって、引戸を開口部の奥行き方向前後にシフトさせる構造にしていた（特許文献１参照）。   Conventionally, in this kind of flat sliding door device, the end of the guide rail that guides the sliding door in the opening and closing direction by engaging the door pulley is curved, and when the sliding door on one side is closed by the guide of the curved portion of the rail, The sliding door is placed in the depth direction of the opening by guiding it to the closing position that closes the opening side by side with the other sliding door and the opening position that overlaps the sliding state when opening and opens the opening. (See Patent Document 1).

しかし、この誘導型のフラット引戸装置では、シフトする一側の引戸が他側の引戸とすれ違うとき、衝突して干渉しないように、閉時に隣り合う引戸端部間の隙間（チリ）を、余裕をもたせて大きく開ける構造にする必要があり、これでは、閉時に、折角、面一に並んだフラット引戸にあっても、外側から見える大きな隙間が原因で見栄えが低下するという課題があった。   However, with this induction type flat sliding door device, when the sliding door on one side shifts from the sliding door on the other side, a clearance (tilt) between the adjacent sliding door ends is not allowed when closing so that it does not collide and interfere. In this case, there is a problem that, when closed, even when the flat sliding doors are lined up at the same angle when closed, the appearance deteriorates due to a large gap visible from the outside.

そこで、従来のフラット引戸装置では、ガイドレール側と引戸側とをリンクで連結し、引戸をリンク運動を介して閉止位置と引違い位置との間で開口部の奥行き方向前後にシフトさせる構造にしたものがある（特許文献２参照）。
特開２００４−２２５４３５号公報 特開２００４−１９３３６号公報 Therefore, in the conventional flat sliding door device, the guide rail side and the sliding door side are connected by a link, and the sliding door is shifted forward and backward in the depth direction of the opening between the closed position and the sliding position via the link motion. (See Patent Document 2).
JP 2004-225435 A JP 2004-19336 A

ところが、従来、リンク式のフラット引戸装置では、構造上、引戸が閉止位置で開閉方向に移動する専用のガイドレールとは別に、同じ引戸が引違い位置で開閉方向へ移動する専用のガイドレールが必要となり、これでは、少なくともガイドレール２本分の軌道スペースを開口部の奥行き方向前後に確保する必要があり、これでは、装置全体の大型化を招いてしまうという課題があった。   However, conventionally, in the link type flat sliding door device, there is a dedicated guide rail for moving the same sliding door in the opening / closing direction at the sliding position apart from the dedicated guide rail moving in the opening / closing direction at the closing position. In this case, it is necessary to secure a track space for at least two guide rails before and after the depth direction of the opening, which causes an increase in the size of the entire apparatus.

そこで、本発明の目的は、閉時は複数の引戸が隙間なく面一に並んだ美観が得られ、引戸のガイドレールは１つで済むコンパクトなフラット引戸装置を提供することにある。   Accordingly, an object of the present invention is to provide a compact flat sliding door device that can provide an aesthetic appearance in which a plurality of sliding doors are arranged flush with each other when closed and only one guide rail is required.

そこで、上記目的を達成すべく、請求項１に記載の発明は、たとえば以下に示す図示実施の形態のとおり、閉時は複数の引戸Ｄ１・Ｄ２・Ｄ３を面一に並べた状態にして開口部Ｓを閉止する一方、開時は引違い状態に重ねて前記開口部Ｓを開けるフラット引戸装置Ａにおいて、前記開口部Ｓの上部側と下部側に敷設し、戸車２７・２８を係合させて各引戸を開閉方向に走行自在に案内する上下一対のガイドレールＧ１・Ｇ２と、前記戸車２７・２８をそれぞれ搭載し、各引戸の上下端部に組み付ける戸車ユニットＲ１・Ｒ２・Ｒ３とを備え、前記ガイドレールＧ１・Ｇ２には、それぞれ幅方向一側の閉止位置に開閉方向に沿って第１軸ガイド溝１５を設けると共に、該第１軸ガイド溝１５と平行な引違い位置に１又は２以上の第２軸ガイド溝２０を設ける一方、これら軸ガイド溝１５・２０間を開閉方向と直交する奥行き方向前後に横断する連絡通路１７・１８・１９を、前記引戸の数だけ開閉方向に所定間隔をあけて設け、各戸車ユニットＲ１・Ｒ２・Ｒ３は、前記連絡通路１７・１８・１９に合わせて幅方向に長い軸挿通穴２６を有し、前記戸車２７・２８を回転自在に軸支した走行フレーム２５と、該走行フレーム２５上に前記軸挿通穴２６と平行に固定側レール３６を固着し、その固定側レール３６に可動側レール３７を互いの係合部３６ａ・３７ａで係合させて摺動自在に連結したスライドレール３５のような連結レールと、ガイド軸４０を縦向きに垂設し、該ガイド軸４０を前記軸挿通穴２６に挿通させて前記連結レールの可動側レール３７に幅方向一側を固定し、他側を、閉時に各ガイド軸４０が前記ガイドレールＧ１・Ｇ２の連絡通路１７・１８・１９と対向する位置で各引戸の上下端部に固定して各引戸と一体に奥行き方向前後に移動可能とする一方、前記走行フレーム２５に対し幅方向一側へ向けて常時ばね付勢してなる取付アーム３０とを備え、閉時は、前記ばね付勢力に基づいて、前記ガイド軸４０が対向する前記連絡通路１７・１８・１９を横断して前記第１軸ガイド溝１５へ係合し、引戸を閉止位置へ自動的にシフトさせる構成としてなることを特徴とする。   Accordingly, in order to achieve the above object, the invention according to claim 1 is configured such that, for example, as shown in the embodiment shown below, a plurality of sliding doors D1, D2, and D3 are arranged in a flush state when closed. In the flat sliding door device A that closes the portion S and opens the opening S in a closed state when opened, it is laid on the upper and lower sides of the opening S, and the door pulleys 27 and 28 are engaged. A pair of upper and lower guide rails G1 and G2 for guiding each sliding door so as to be able to run freely in the opening and closing direction, and doorwheel units R1, R2 and R3 mounted on the upper and lower ends of each sliding door. Each of the guide rails G1 and G2 is provided with a first shaft guide groove 15 along the opening / closing direction at a closed position on one side in the width direction, and 1 or 2 at a sliding position parallel to the first shaft guide groove 15. 2 or more second shaft guide grooves On the other hand, connecting passages 17, 18, and 19 that cross between the shaft guide grooves 15, 20 in the depth direction orthogonal to the opening / closing direction are provided at predetermined intervals in the opening / closing direction by the number of the sliding doors. The vehicle units R1, R2, and R3 have shaft insertion holes 26 that are long in the width direction in accordance with the communication passages 17, 18, and 19, and a traveling frame 25 that rotatably supports the door wheels 27 and 28, A fixed rail 36 is fixed on the traveling frame 25 in parallel with the shaft insertion hole 26, and a movable rail 37 is engaged with the fixed rail 36 by mutual engaging portions 36a and 37a so as to be slidably connected. The connecting rail such as the slide rail 35 and the guide shaft 40 are vertically suspended, and the guide shaft 40 is inserted into the shaft insertion hole 26 so that one side in the width direction is placed on the movable rail 37 of the connecting rail. Fixed and other When closed, each guide shaft 40 is fixed to the upper and lower ends of each sliding door at a position facing the communication passages 17, 18, 19 of the guide rails G 1, G 2, and can be moved back and forth in the depth direction integrally with each sliding door. On the other hand, a mounting arm 30 that is always spring-biased toward the one side in the width direction with respect to the traveling frame 25 is provided, and when closed, the guide shaft 40 faces the guide shaft 40 based on the spring-biasing force. It is characterized in that the sliding door is automatically shifted to the closed position by crossing the communication passages 17, 18, 19 and engaging with the first shaft guide groove 15.

したがって、請求項１に記載の発明によれば、開時は、開けたい引戸を奥行き方向手前側へ引き寄せると、戸車ユニットのガイド軸が第２軸ガイド溝への連絡通路の真向かいで第１軸ガイド溝に係合しているため、走行フレーム上で連結レールの可動側レールがばね付勢力に抗して摺動して取付アームを走行フレームに対して奥行き方向手前へ移動し、それに従って、ガイド軸が第１軸ガイド溝から連絡通路を開閉方向と直交する奥行き方向に横断して第２軸ガイド溝へ係合し、引戸が引違い位置へ引き出される一方、閉時は、ばね付勢力に基づいて、ガイド軸が対向する連絡通路を開閉方向と直交する奥行き方向に横断して第１軸ガイド溝へ係合し、引戸を閉止位置にシフトさせる構成であるため、閉時には、複数の引戸が隙間なく面一に並んだ美観を得ることができると共に、開閉時に引戸を案内するガイドレールは１つで済むコンパクトな構造のフラット引戸装置を提供することができる。   Therefore, according to the first aspect of the present invention, when the sliding door to be opened is pulled toward the near side in the depth direction when opened, the guide shaft of the door roller unit is directly opposite to the communication path to the second shaft guide groove. Since it is engaged with the guide groove, the movable rail of the connecting rail slides against the spring biasing force on the traveling frame and moves the mounting arm to the near side in the depth direction with respect to the traveling frame. The guide shaft crosses the connecting passage from the first shaft guide groove in the depth direction perpendicular to the opening / closing direction and engages with the second shaft guide groove, and the sliding door is pulled out to the sliding position, while when closed, the spring biasing force Based on the above, the connecting passage that the guide shaft faces is crossed in the depth direction orthogonal to the opening and closing direction, engages with the first shaft guide groove, and the sliding door is shifted to the closed position. Sliding doors are flush with each other It is possible to obtain the appearance I, guide rails for guiding the sliding door during opening and closing can provide a flat sliding door device of a compact structure requires only one.

しかも、請求項１に記載の発明によれば、開時に、複数の引戸を引違い状態に重ね合わせて後、これら引戸Ｄを引違い状態で重ねたまま、まとめて開閉方向へ引くと、引違い位置の引戸は、戸車ユニットのガイド軸を第２軸ガイド溝に沿って移動させならが、ガイドレールの案内でスライドすると同時に、閉止位置の引戸は、戸車ユニットのガイド軸を第１軸ガイド溝に沿って移動させながら、同じガイドレールの案内でスライドし、これら複数の引戸をまとめて重ね合わせたまま、片側に寄せて移動させることができ、その結果、開口部を、引戸数枚分も大きく開放したり、適宜に開口面積を広く確保することができる。   Moreover, according to the first aspect of the present invention, when the plurality of sliding doors are overlapped in the sliding state when opened, and the sliding doors D are overlapped in the sliding state and pulled together in the opening and closing direction, If the sliding door at the different position moves the guide shaft of the door roller unit along the second shaft guide groove, the sliding door at the closed position simultaneously slides the guide shaft of the door wheel unit along the first shaft guide groove. While moving along the groove, slide with the guide of the same guide rail, and these multiple sliding doors can be moved to one side while being overlapped together. As a result, the opening part is equivalent to several sliding doors Can be widely opened, and a wide opening area can be secured as appropriate.

The second shaft guide groove 20 is formed at a position where the two shaft guides are moved at the same time. The number of sliding doors D1, D2, and D3 is provided at a predetermined interval. Therefore, the guide rails G1 and G2 are constructed by fixing the mounting plate portion 11 to the top plate upper surface 21 and the bottom plate lower surface 22 of the storage main body 10 along the opening / closing direction.

戸車ユニットＲ１・Ｒ２・Ｒ３は、図４〜図６にも示すように、走行フレーム２５および取付アーム３０と、これらに組み付ける構成部品からなる。   As shown in FIGS. 4 to 6, the door cart units R1, R2, and R3 are composed of the traveling frame 25 and the mounting arm 30, and components that are assembled to these.

走行フレーム２５は、金属板をやや扁平なコ形状に曲げ成形し、平板部２５ａと、平板部２５ａの幅方向両側のローラ保持片部２５ｂとからなる。平板部２５ａには、略中間位置に、連絡通路１７・１８・１９に対応させて幅方向に長くあけた軸挿通穴２６を設けてなる。なお、両端の第１引戸Ｄ１および第３引戸Ｄ３に備えた戸車ユニットＲ１・Ｒ３において、ローラ保持片部２５ｂには、長手方向一端側に、互いに平行に伸びた突片部分２５ｃを有するが、中間の第２引戸Ｄ２に備えた戸車ユニットＲ２において、ローラ保持片部２５ｂには、長手方向両端側に、互いに平行に伸びた突片部分２５ｃを有してなる。   The traveling frame 25 is formed by bending a metal plate into a slightly flat U shape, and includes a flat plate portion 25a and roller holding piece portions 25b on both sides in the width direction of the flat plate portion 25a. The flat plate portion 25a is provided with a shaft insertion hole 26 that is long in the width direction so as to correspond to the communication passages 17, 18, and 19 at a substantially intermediate position. In the door roller units R1 and R3 provided in the first sliding door D1 and the third sliding door D3 at both ends, the roller holding piece portion 25b has projecting piece portions 25c extending in parallel with each other on one end side in the longitudinal direction. In the door cart unit R2 provided in the intermediate second sliding door D2, the roller holding piece portion 25b has projecting piece portions 25c extending in parallel with each other on both ends in the longitudinal direction.

かかる形状の走行フレーム２５は、ローラ保持片部２５ｂの向い合う内面側に、それぞれ戸車の走行ローラ２７を縦向きに立てた状態で回転自在に軸支し、横振れ防止用のガイドローラ２８はＬ板状軸受片２９を介して横向きに寝かせた状態で回転自在に軸支している。なお、中間の第２引戸Ｄ２の戸車ユニットＲ２において、ローラ保持片部２５ｂで保持する走行ローラ２７およびガイドローラ２８の支持高さ位置を、両端の引戸Ｄ１・Ｄ３の戸車ユニットＲ１・Ｒ３におけるローラ２７・２８の支持高さ位置より、ガイドレールＧ１・Ｇ２のローラ係合部１１ａ・１１ｂの高さ位置の違いに対応させて、一段高くしている。   The traveling frame 25 having such a shape is rotatably supported on the inner surface of the roller holding piece 25b facing each other in a state where the traveling roller 27 of the door roller is vertically oriented, and a guide roller 28 for preventing lateral vibration is provided. It is pivotally supported in a state where it is laid down sideways via an L-plate bearing piece 29. It should be noted that, in the door pulley unit R2 of the intermediate second sliding door D2, the support height positions of the traveling roller 27 and the guide roller 28 held by the roller holding piece 25b are set to the rollers in the door wheel units R1 and R3 of the sliding doors D1 and D3 at both ends. The support height positions 27 and 28 are made higher by one step corresponding to the difference in height positions of the roller engaging portions 11a and 11b of the guide rails G1 and G2.

更に、走行フレーム２５は、平板部２５ａ上において、軸挿通穴２６を間に挟んだ長手方向両端寄りに一対のスライドレール（連結レール）３５を、スライドレール３５と軸挿通穴２６間に一対の付勢ばね５５・５６を、片方の付勢ばね５５と軸挿通穴２６間にダンパ５０を、それぞれ装着している。   Further, the traveling frame 25 has a pair of slide rails (connection rails) 35 on the flat plate portion 25a near the both ends in the longitudinal direction with the shaft insertion hole 26 therebetween, and a pair of slide rails 35 and the shaft insertion hole 26. The biasing springs 55 and 56 are mounted on the damper 50 between the biasing spring 55 on one side and the shaft insertion hole 26, respectively.

スライドレール３５は、それぞれ両側縁に内向きに湾曲した係合部３６ａを有する固定側レールのアウターレール３６と、両側縁に外向きに湾曲した係合部３７ａを有する可動側レールのインナーレール３７とを、互いの係合部３６ａ・３７ａにおいて、図示省略するリテーナで保持した多数のボールを介して係合させて摺動自在に連結した扁平な構造になっている。そこで、スライドレール３５は、アウターレール３６を、平板部２５ａ上に軸挿通穴２６と平行な幅方向に固着して走行フレーム２５に装着している。   The slide rail 35 has a fixed-side rail outer rail 36 having inwardly curved engaging portions 36a on both side edges, and a movable-side rail inner rail 37 having outwardly curved engaging portions 37a on both side edges.

Therefore, the slide rail 35 is attached to the traveling frame 25 by fixing the outer rail 36 on the flat plate portion 25 a in the width direction parallel to the shaft insertion hole 26.

ダンパ５０は、直方形のダンパケース５１内に胴筒を収納し、胴筒から先端軸部５２ａを突出させた制動軸５２を胴筒内で軸方向に往復動可能に保持する一方、制動軸５２と胴筒の内周面間の隙間にオイルを充填して胴筒内に密封し、先端軸部５２ａ側から制動軸５２を胴筒内へ押し込むと、オイルの粘性抵抗により制動力を発生させる、所謂オイルダンパからなる。そこで、ダンパ５０は、平板部２５ａ上に、制動軸５２の先端軸部５２ａを幅方向他側へ向けて、ダンパケース５１を固着して走行フレーム２５に装着している。   The damper 50 houses a barrel in a rectangular damper case 51, and holds a brake shaft 52 having a distal end shaft portion 52a protruding from the barrel so as to be reciprocable in the axial direction. Oil is filled in the gap between the inner peripheral surface of the cylinder 52 and the cylinder and sealed in the cylinder, and when the brake shaft 52 is pushed into the cylinder from the tip shaft 52a side, a braking force is generated by the viscous resistance of the oil. It consists of a so-called oil damper. Therefore, the damper 50 is attached to the traveling frame 25 with the damper case 51 fixed on the flat plate portion 25a with the tip shaft portion 52a of the braking shaft 52 facing the other side in the width direction.

付勢ばね５５・５６は、それぞれ圧縮コイルバネで、ばね一端５５ａ・５６ａを、平板部２５ａ上において幅方向一側に突設した一対のバネ掛けピン５３に掛け止め、ばね他端５５ｂ・５６ｂは、取付アーム３０側のバネ掛けピン５９に掛け止めるようになっている。   The urging springs 55 and 56 are compression coil springs, respectively, and one end of the springs 55a and 56a are latched to a pair of spring hooking pins 53 protruding on one side in the width direction on the flat plate portion 25a, and the other spring ends 55b and 56b are The spring is hooked on a spring hook pin 59 on the mounting arm 30 side.

この取付アーム３０は、いずれも金属製の、取付板３１と、取付板の幅方向他側に一片３２ａをねじ止めする断面Ｌ形のアングル材３２とからなり、取付板３１の中央には、ガイド軸４０を縦向きに垂設している。取付板３１は、下面において、幅方向他側の側縁にダンパ押圧板片４１を、長さ方向一端の端縁にコロ支持板片５７をそれぞれねじ止めしてガイド軸４０と同じく垂下している。コロ支持板５７は、横振れ防止用のコロ５８を、スライドレール３５に対応させて幅方向前後へ回転可能に軸支している。また、取付板３１の下面には、幅方向他側に一対のバネ掛けピン５９を突設してなる。   This mounting arm 30 is composed of a metal mounting plate 31 and an L-shaped angle member 32 having a cross-section L shape that screws one piece 32a to the other side in the width direction of the mounting plate. The guide shaft 40 is vertically suspended. On the lower surface of the mounting plate 31, the damper pressing plate piece 41 is screwed to the side edge on the other side in the width direction, and the roller support plate piece 57 is screwed to the edge of one end in the length direction, respectively. Yes. The roller support plate 57 pivotally supports a roller 58 for preventing lateral shaking so as to be able to rotate back and forth in the width direction in correspondence with the slide rail 35. In addition, a pair of spring hook pins 59 project from the lower surface of the mounting plate 31 on the other side in the width direction.

そこで、戸車ユニットＲ１・Ｒ２・Ｒ３は、それぞれガイド軸４０を軸挿通穴２６に挿通し、横振れ防止用コロ５８を平板部２５ａ上に載置させた状態で、取付板３１の幅方向一側を走行フレーム２５上でインナーレール３７に固着し、取付アーム３０を走行フレーム２５に対し幅方向前後に移動可能に装着する。また、付勢ばね５５・５６のばね他端５５ｂ・５６ｂを、取付アーム３０側のバネ掛けピン５９に掛け止めて、取付アーム３０を走行フレームに対し幅方向一側へ向けて常時ばね付勢し、図６に示すように、互いに重なり合った態に組み立てる。次いで、戸車ユニットＲ１・Ｒ２・Ｒ３は、それぞれアングル材３２の長手な他片３２ｂを引戸Ｄ１・Ｄ２・Ｄ３の上下端部内面にねじ止めし、図１および図２に示すように、引戸Ｄ１・Ｄ２・Ｄ３上に片側に向けて鍔状に張り出し状態で組み付ける。このとき、戸車ユニットＲ１・Ｒ２・Ｒ３は、それぞれ搭載した引戸Ｄ１・Ｄ２・Ｄ３が隙間なく面一に並んで開口部Ｓを閉止した状態にあるとき、各ガイド軸４０がそれぞれガイドレールＧ１・Ｇ２の連絡通路１７・１８・１９と対向する位置で引戸Ｄ１・Ｄ２・Ｄ３の上下端部内面に固定する。   Therefore, each of the door units R1, R2, and R3 has the guide shaft 40 inserted through the shaft insertion hole 26, and the horizontal runout prevention roller 58 is placed on the flat plate portion 25a. The side is fixed to the inner rail 37 on the traveling frame 25, and the mounting arm 30 is attached to the traveling frame 25 so as to be movable forward and backward in the width direction. Further, the other spring ends 55b and 56b of the urging springs 55 and 56 are latched to spring mounting pins 59 on the mounting arm 30 side, and the mounting arm 30 is always urged toward the width direction with respect to the traveling frame. Then, as shown in FIG. Next, the door pulley units R1, R2, and R3 screw the other long pieces 32b of the angle members 32 to the inner surfaces of the upper and lower ends of the sliding doors D1, D2, and D3, respectively, and as shown in FIGS. 1 and 2, the sliding door D1・ Assemble on the D2 and D3 in a hooked shape toward one side. At this time, when the door units R1, R2, and R3 are in a state in which the sliding doors D1, D2, and D3 mounted on the doors are lined up flush with each other and the opening S is closed, the guide shafts 40 are respectively guided by the guide rails G1, The sliding doors D1, D2, and D3 are fixed to the inner surfaces of the upper and lower ends of the sliding doors D1, D2, and D3 at positions facing the communication passages 17, 18, and 19 of G2.

それから、第１引戸Ｄ１は、戸車ユニットＲ１のガイド軸４０を、ガイドレールＧ１・Ｇ２の連絡通路１７と対向する位置で、第１軸ガイド溝１５に係合させると共に、ローラ２７・２８を第１のローラ係合部１１ａに係合させて収納本体１０に吊り込む。第２引戸Ｄ２は、戸車ユニットＲ２のガイド軸４０を、連絡通路１８と対向する位置で第１軸ガイド溝１５に係合させると共に、ローラ２７・２８を一段高い第２のローラ係合部１１ｂに係合させて収納本体１０に吊り込む。第３引戸Ｄ３は、図３に示すように、戸車ユニットＲ３のガイド軸４０を、連絡通路１９と対向する位置で、第１軸ガイド溝１５に係合させると共に、ローラ２７・２８を第１のローラ係合部１１ａに係合させて収納本体１０に吊り込。こうして引戸Ｄ１・Ｄ２・Ｄ３を、隙間なく面一に並べて開口部Ｓを閉止した状態で収納本体１０に組み付ける。   Then, the first sliding door D1 engages the guide shaft 40 of the door roller unit R1 with the first shaft guide groove 15 at a position facing the communication passage 17 of the guide rails G1 and G2, and the rollers 27 and 28 are moved to the first sliding door D1. 1 is engaged with the roller engaging portion 11 a and is suspended in the storage body 10. The second sliding door D2 engages the guide shaft 40 of the door roller unit R2 with the first shaft guide groove 15 at a position facing the communication passage 18, and the rollers 27 and 28 are raised by the second roller engaging portion 11b. And is suspended in the storage body 10. As shown in FIG. 3, the third sliding door D <b> 3 engages the guide shaft 40 of the door cart unit R <b> 3 with the first shaft guide groove 15 at a position facing the communication passage 19, and the rollers 27 and 28 are connected to the first sliding door D <b> 3. It is engaged with the roller engaging portion 11a and suspended in the storage body 10. In this way, the sliding doors D1, D2, and D3 are assembled to the storage main body 10 in a state where the sliding doors D1, D2, and D3 are arranged flush with each other and the opening S is closed.

さて、上述した構成のフラット引戸装置Ａにおいて、クロゼット構造体Ｃを開ける場合は、面一に並んで閉状態ある引戸Ｄ１・Ｄ２・Ｄ３の中から、開ける引戸を１つ選んで、例えば図中右端の第３引戸Ｄ３を、不図示の取手を持って図中手前側へ引き寄せる。すると、戸車ユニットＲ３のガイド軸４０の先端軸部４０ａが第２軸ガイド溝２０への連絡通路１９の真向かいで第１軸ガイド溝１５に係合しているため、走行フレーム２５上でアウターレール３６に対しインナーレール３７が付勢ばね５５・５６に抗して摺動して取付アーム３０を走行フレーム２５に対して奥行き方向手前へ移動し、それに従って、図７に示すように、ガイド軸４０が第１軸ガイド溝１５から連絡通路１９を横断して第２軸ガイド溝２０へ係合し、第３引戸Ｄ３は引違い位置へ、いったん引き出される。なお、このとき同時に、走行フレーム２５の平板部２５ａ上を横振れ防止用コロ５８が幅方向後方へ転動し、これにより、スライドレール３５のアウターレール３６に対するインナーレール３７の摺動方向を規制してインナーレール３７を横振れなく直進させ、その結果、第３引戸Ｄ３は引違い位置へガタつかずにスムーズに引き出される。   Now, in the case of opening the closet structure C in the flat sliding door device A configured as described above, one sliding door to be opened is selected from the sliding doors D1, D2, and D3 that are in a line and are closed, for example, in the figure. The third sliding door D3 at the right end is pulled toward the front side in the figure with a handle (not shown). Then, since the front end shaft portion 40a of the guide shaft 40 of the door pulley unit R3 is engaged with the first shaft guide groove 15 directly opposite to the communication passage 19 to the second shaft guide groove 20, the outer rail on the travel frame 25 is engaged. The inner rail 37 slides against the urging springs 55 and 56 against the urging spring 36 to move the mounting arm 30 forward in the depth direction with respect to the traveling frame 25. Accordingly, as shown in FIG. 40 crosses the communication passage 19 from the first shaft guide groove 15 and engages with the second shaft guide groove 20, and the third sliding door D3 is once pulled out to the sliding position. At the same time, the lateral shake prevention roller 58 rolls backward in the width direction on the flat plate portion 25a of the traveling frame 25, thereby restricting the sliding direction of the inner rail 37 with respect to the outer rail 36 of the slide rail 35. As a result, the inner rail 37 is moved straight without swinging. As a result, the third sliding door D3 is smoothly pulled out without rattling to the sliding position.

それから、第３引戸Ｄ３を付勢ばね５５・５６に抗しながら隣の第２引戸Ｄ２と重なる側へ引くと、図８に示すように、ガイド軸４０を第２軸ガイド溝２０に係合させながら、走行ローラ２７とガイドローラ２８がガイドレールＧ１・Ｇ２の第１ローラ係合部１１ａを転動して横振れなく走行し、第３引戸Ｄ３を第２引戸Ｄ２に引違い状態に重ねて開口部Ｓの右側を引戸１枚分、開放することができる。   Then, when the third sliding door D3 is pulled toward the side overlapping the adjacent second sliding door D2 while resisting the biasing springs 55 and 56, the guide shaft 40 is engaged with the second shaft guide groove 20 as shown in FIG. The running roller 27 and the guide roller 28 roll on the first roller engaging portion 11a of the guide rails G1 and G2 and run without lateral shaking, and the third sliding door D3 is overlapped with the second sliding door D2 in a closed state. Thus, the right side of the opening S can be opened for one sliding door.

次いで、閉時は、第３引戸Ｄ３を付勢ばね５５・５６に抗しながら逆向きに引き戻し、戸車ユニットＲ３のガイド軸４０が第２軸ガイド溝２０に沿って移動して後、先端軸部４０ａが第１軸ガイド溝１５への連絡通路１９の真向かい位置に至ると、付勢ばね５５・５６のばね付勢力が働いて、走行フレーム２５上でアウターレール３６に対しインナーレール３７が逆向きに摺動して取付アーム３０を走行フレーム２５に対し奥行き方向後側へ移動し、それに従って、ガイド軸４０が連絡通路１９を横断して元の第１軸ガイド溝１５に係合し、第３引戸Ｄ３を閉止位置へ自動的に引き込んで、他の引戸Ｄ１・Ｄ２と隙間なく面一に並んで開口部Ｓを閉止する。このとき、ダンパ５０の制動軸５２の先端軸部５２ａに、取付アーム３０側のダンパ押圧板片４１が当たり、第３引戸Ｄ３の引込み動作に従って制動軸５２が胴筒内へ押し込まれる。すると、第３引戸Ｄ３の引込み動作にオイルの粘性抵抗による制動力が働き、その結果、第３引戸Ｄ３は、一気に閉止位置へ引き込まれてバターンと衝突音を発生することなく、閉止位置の直前では、ゆっくり引き込まれてスムーズに閉止することができる。   Next, when closed, the third sliding door D3 is pulled back in the opposite direction against the biasing springs 55 and 56, and the guide shaft 40 of the door wheel unit R3 moves along the second shaft guide groove 20, and then the tip shaft When the portion 40a reaches a position directly opposite to the communication passage 19 to the first shaft guide groove 15, the spring biasing force of the biasing springs 55 and 56 acts, and the inner rail 37 is reversed with respect to the outer rail 36 on the traveling frame 25. Sliding in the direction to move the mounting arm 30 rearward in the depth direction with respect to the traveling frame 25, and accordingly, the guide shaft 40 crosses the communication passage 19 and engages the original first shaft guide groove 15, The third sliding door D3 is automatically pulled to the closing position, and the opening S is closed in line with the other sliding doors D1 and D2 without any gap. At this time, the damper pressing plate piece 41 on the mounting arm 30 side hits the tip end shaft portion 52a of the braking shaft 52 of the damper 50, and the braking shaft 52 is pushed into the barrel according to the retracting operation of the third sliding door D3. Then, the braking force due to the viscous resistance of the oil acts on the retracting operation of the third sliding door D3. As a result, the third sliding door D3 is immediately pulled to the closing position and does not generate a pattern and collision sound, and immediately before the closing position. Then, it can be pulled in slowly and closed smoothly.

また、上述した開時に、例えば第３引戸Ｄ３を、引違い位置へ引き出してから、中間の第２引戸Ｄ２と引違い状態に重なる位置までスライドさせて後、この引戸Ｄ２と引違い状態で重なったまま、一緒に逆向きに引き戻せば、第３引戸Ｄ３は、戸車ユニットＲ３のガイド軸４０を第２軸ガイド溝２０に沿って移動しならが、ローラ２７・２８がガイドレールＧ１・Ｇ２の第１ローラ係合部１１ａを走行してスライドすると同時に、第２引戸Ｄ２は、戸車ユニットＲ２のガイド軸４０を第１軸ガイド溝１５に沿って移動しながら、ローラ２７・２８が同じガイドレールＧ１・Ｇ２の第２ローラ係合部１１ｂを走行してスライドし、両引戸Ｄ２・Ｄ３を重ねたまま移動させることができる（図８参照）。そうすれば、引違い状態で重ねた引戸Ｄ２・Ｄ３と、図中左端の第１引戸Ｄ１間の中間で開口部Ｓを引戸１枚分、開放することもできる。   Further, at the time of opening described above, for example, the third sliding door D3 is pulled out to the sliding position and then slid to a position overlapping with the intermediate second sliding door D2, and then overlapped with the sliding door D2 in the sliding state. If the third sliding door D3 moves back along the second shaft guide groove 20 by moving the guide shaft 40 of the door roller unit R3 along with the guide rails G1 and G2, At the same time as the second sliding door D2 moves and slides along the first shaft guide groove 15, the rollers 27 and 28 are guided by the same guide. The second roller engaging portion 11b of the rails G1 and G2 can travel and slide, and the sliding doors D2 and D3 can be moved while being overlapped (see FIG. 8). If it does so, the opening part S can also be open | released by one sliding door in the middle between the sliding doors D2 * D3 piled up in the sliding state, and the 1st sliding door D1 of the left end in the figure.

ところで、上記図示実施の形態では、開口部Ｓを開閉する引戸が３枚のクロゼット構造体Ｃに付設した例を示したが、本発明は、上記図示例に限らず、２枚又は４枚以上のフラット引戸にも適用することができる。図９には、本発明のフラット引戸装置（図示省略）を引戸が４枚のクロゼット構造体Ｃに適用した例を示している。従って、図示他例のフラット引戸装置では、ガイドレールＧ１・Ｇ２に、軸ガイド溝１５・２０間を直角に横断する連絡通路を、引戸の数に合わせて４個所、所定間隔をあけて設ける。一方、第４引戸Ｄ４には、中間の第２引戸Ｄの戸車ユニットＲ２と同じ構造の戸車ユニットを搭載し、この第４の戸車ユニットは、引戸Ｄ１〜Ｄ４を面一に並べて開口部Ｓを閉止した状態にあるとき、ガイド軸４０が対応する第４の連絡通路と対向する位置で第４引戸Ｄ４の上下端部内面に固定する。   By the way, in the illustrated embodiment, the example in which the sliding door for opening and closing the opening S is attached to the three closet structures C is shown. However, the present invention is not limited to the illustrated example, and two or four or more sheets are provided. It can also be applied to flat sliding doors. FIG. 9 shows an example in which the flat sliding door device (not shown) of the present invention is applied to a closet structure C having four sliding doors. Therefore, in the flat sliding door device of the other example shown in the figure, the guide rails G1 and G2 are provided with four connecting passages that intersect the shaft guide grooves 15 and 20 at right angles at predetermined intervals according to the number of sliding doors. On the other hand, the fourth sliding door D4 is equipped with a door car unit having the same structure as the door car unit R2 of the intermediate second sliding door D, and the fourth door car unit has the openings S with the sliding doors D1 to D4 arranged in a plane. When in the closed state, the guide shaft 40 is fixed to the inner surfaces of the upper and lower ends of the fourth sliding door D4 at a position facing the corresponding fourth communication passage.

従って、図示他例では、クロゼット構造体Ｃを開ける場合、図９（Ａ）に示すように、例えば第２引戸Ｄ２と第４引戸Ｄ４を引違い位置へ引き出してから、それぞれ隣の第１引戸Ｄ１と第３引戸と引違い状態に重なる位置まで左右にスライドさせれば、開口部Ｓを中間で引戸２枚分、大きく開けることができる。また、同図（Ｂ）に示すように、例えば第２引戸Ｄ２と第３引戸Ｄ３を引違い位置へ引き出してから、それぞれ隣の第１引戸Ｄ１と第４引戸と引違い状態に重なる位置までスライドさせれば、開口部Ｓを引戸１枚おきに２個所、大きく開口させることができる。更に、同図（Ｃ）に示すように、例えば第２引戸Ｄ２と第３引戸Ｄ３を引違い位置へ引き出し、それぞれ隣の第１引戸Ｄ１と第４引戸と引違い状態に重なる位置までスライドさせて後、第３引戸Ｄ３を第２引戸Ｄ２と引違い状態で重ねたまま一緒に片側へ移動することができ、そうすれば、開口部Ｓの他側を引戸２枚分も大きく開放することができる。   Accordingly, in the other example shown in the figure, when the closet structure C is opened, as shown in FIG. 9A, for example, the second sliding door D2 and the fourth sliding door D4 are pulled out to the sliding position, and then the adjacent first sliding door. If it slides to the left and right to the position which overlaps with D1 and the 3rd sliding door, the opening part S can be opened large by two sliding doors in the middle. Further, as shown in FIG. 5B, for example, after the second sliding door D2 and the third sliding door D3 are pulled out to the sliding position, the adjacent first sliding door D1 and the fourth sliding door are overlapped with the sliding position. If it slides, the opening part S can be opened largely in two places every other sliding door. Further, as shown in FIG. 5C, for example, the second sliding door D2 and the third sliding door D3 are pulled out to the sliding position, and are slid to the positions where they overlap with the adjacent first sliding door D1 and the fourth sliding door, respectively. After that, the third sliding door D3 can be moved to one side together with the second sliding door D2 overlapped with the second sliding door D2, and the other side of the opening S is greatly opened as much as two sliding doors. Can do.

以上の図示実施の形態では、ガイドレールＧ１・Ｇ２の引違い位置に第２軸ガイド溝２０を１本設けるが、本発明のフラット引戸装置では、引違い状態で重ねる引戸の数に応じて複数の第２軸ガイド溝を設けるようにすることもできる。   In the above-described illustrated embodiment, one second shaft guide groove 20 is provided at the sliding position of the guide rails G1 and G2. In the flat sliding door device of the present invention, a plurality of sliding doors are stacked depending on the number of sliding doors stacked in the sliding state. It is also possible to provide a second shaft guide groove.
