【００１９】
このようであるから、第１戸車２の車輪２６（第１障子１の面内方向一側部）は補助レール部５４を通って第１レール１０と第２レール１１とに亘って面外方向に斜めに移動する。
【００２０】
前記第２ブロック５２に案内部材５５が縦軸５６で面外方向に揺動自在に取付けてある。
この案内部材５５はコイルスプリング等の弾性材で面外方向他側に向けて揺動付勢されて図６に示すように第１ブロック５１の取付部５０ａの面５１ｃに当接し、補助レール部５４を閉じている。
【００２１】
前記第２補助レール６０は図５、図６に示すように、第１レール１０の前述した隔壁１０ｂと第２レール１１の前述した隔壁１１ｂを所定の長さに切欠きした切欠き部１０ｄ、１１ｅにおいて上枠４の上横板４ａの下面にボルト６１で取付けてある。

【００２２】
このようであるから、第１障子１の第１戸車２（第１障子１の面内方向他側部）は補助レール部６４に沿って面外方向に斜めに移動する。
【００２３】
前記第２障子６の第２戸車７は前述した第１の実施の形態における第２障子６の第２戸車７と同一である。
【００２４】
次に障子の開閉動作を説明する。
図７（ａ）に示すように第１障子１と第２障子６が閉じ位置の時には、第１障子１の一方の第１戸車２は第２レール１１に接し、他方の戸車２は第２補助レール６０の補助レール部６４の面外方向他側端部６４ｂに位置する。
これによって第１障子１と第２障子６は面外方向に面一である。
案内部材５５は一方の第１戸車２に接して面外方向一側に揺動し、補助レール部５４を開いている。
【００２５】
前述の状態から第１障子１を開き位置に向けて移動すると、一方の第１戸車２が第１補助レール５０の補助レール部５４、他方の第１戸車２が第２補助レール部６０の補助レール部６４に沿ってそれぞれ面外方向一側に向けて斜め（矢印ｂ）に移動し、図７（ｂ）のように各第１戸車２が第１レール１０に接する。
この時、一方の戸車２が第２レール１１に沿って第２障子６側に移動することが案内部材５５で防止されるので、第１障子１と第２障子６が誤って衝突することがない。
第１障子１が第１レール１０側に移動すると案内部材５５は第１補助レール５０の第１ブロック５１に当接する。
【００２６】
前述の状態で第２障子６を第２レール１１に沿って開き位置に向けて移動する時に、第２戸車７が案内部材５５と干渉しないので開き位置に向けて第２レール１１に沿って移動できる。
これにより、第２障子６を図７（ｄ）を示すように開き位置まで移動できる。この時、第１補助レール５０の補助レール部５４は案内部材５５で閉じられているので、第２障子６が第１レール１０側に移動することがない。
【００２７】
前述の実施の形態の引戸は、カーテンウォールの窓部の近くに取付けられて窓部との間に中間空気層を形成し、その中間空気層に空気を流通して室内を換気するように利用される。なお、これ以外にも利用できることは勿論である。
【００２８】
【発明の効果】
請求項１に係る発明によれば、第１障子が第１レールに沿って開き位置から閉じ位置に向けて移動して閉じ位置近くになると、第１・第２補助レールの補助レール部に沿って第１障子の面内方向一側部、面内方向他側部が面外方向一側に向けて移動して第２レールに移動し、閉じ位置において第１障子と第２障子が面外方向に略同一位置となる。
これによって、引戸を閉じた時に第１障子と第２障子に面外方向の段差が生じないので、見栄えが良い。
【００２９】
第１障子が閉じ位置近くと開き位置との間を移動する時には第１レールに沿って移動し、第１障子は面外方向に動くことなしに第１レールに沿って面内方向に移動する。
また、第１障子が閉じ位置から第２レールに沿って開き位置に向けて移動することが案内部材で阻止される。
これによって、第１障子を開閉移動する時に誤って第２障子と衝突する恐れがない。

The second door 7 of the second shoji 6 is the same as the second door 7 of the second shoji 6 in the first embodiment described above.
[0024]
Next, the opening / closing operation of the shoji will be described.
As shown in FIG. 7A, when the first shoji 1 and the second shoji 6 are in the closed position, one first door 2 of the first shoji 1 is in contact with the second rail 11 and the other door 2 is second. The auxiliary rail 60 is located at the other end 64b in the out-of-plane direction of the auxiliary rail portion 64.
Accordingly, the first shoji 1 and the second shoji 6 are flush with each other in the out-of-plane direction.
The guide member 55 is in contact with one first door 2 and swings in one out-of-plane direction to open the auxiliary rail portion 54.
[0025]
When the first shoji 1 is moved from the above-described state toward the open position, one first door 2 is the auxiliary rail portion 54 of the first auxiliary rail 50, and the other first door 2 is the auxiliary of the second auxiliary rail portion 60. Each of the first doors 2 is in contact with the first rail 10 as shown in FIG.
At this time, the guide member 55 prevents one of the door pulleys 2 from moving toward the second shoji 6 along the second rail 11, so that the first shoji 1 and the second shoji 6 may collide accidentally. Absent.
When the first shoji 1 moves to the first rail 10 side, the guide member 55 comes into contact with the first block 51 of the first auxiliary rail 50.
[0026]
When the second shoji 6 is moved along the second rail 11 toward the opening position in the state described above, the second door 7 does not interfere with the guide member 55 and therefore moves along the second rail 11 toward the opening position. it can.
Thereby, the 2nd shoji 6 can be moved to an open position, as shown in FIG.7 (d). At this time, since the auxiliary rail portion 54 of the first auxiliary rail 50 is closed by the guide member 55, the second shoji 6 does not move to the first rail 10 side.
[0027]
The sliding door of the above-mentioned embodiment is used in such a way that an intermediate air layer is formed between the curtain wall and the window portion, and air is circulated through the intermediate air layer to ventilate the room. Is done. Of course, it can be used other than this.

【The invention's effect】
According to the first aspect of the present invention, when the first shoji moves along the first rail from the open position toward the closed position and approaches the closed position , the first shoji is moved along the auxiliary rail portions of the first and second auxiliary rails. The one side in the in-plane direction and the other side in the in-plane direction move toward one side in the out-of-plane direction and move to the second rail , and the first and second shoji are out-of-plane at the closed position. It becomes substantially the same position in the direction.
Thereby, when the sliding door is closed, there is no step in the out-of-plane direction between the first shoji and the second shoji, so the appearance is good.
[0029]
When the first shoji moves between the close position and the open position, it moves along the first rail, and the first shoji moves in the in-plane direction along the first rail without moving in the out-of-plane direction. .
Further, the guide member prevents the first shoji from moving from the closed position along the second rail toward the open position.
Thus, there is no risk of accidentally colliding with the second shoji when the first shoji is opened and closed.
[0030]
Moreover, since the guide member allows the second shoji to move toward the open position, the second shoji can be moved along the second rail between the closed position and the open position.
