ところで、本実施の形態による乗場ドア７Ａ，７Ｂは、乗降口４を中央から両側に横方向に開閉する、所謂２枚戸中央開き乗場ドアであるので、各乗場ドア７Ａ，７Ｂの戸当たり側には、乗場ドア７Ａ，７Ｂ同士が直接突き当たって衝突音やドアが損傷しないように、夫々戸当たりゴム３６Ａ，３６Ｂが設けられている。この戸当たりゴム３６Ａ，３６Ｂを設けることにより、対向する乗場ドア７Ａ，７Ｂの戸当たり側には、図１，図１２〜図１５に示すように、隙間Ｇ３を設けてドア閉じ時に直接乗場ドア７Ａ，７Ｂが衝突しないようにしている。そして、この隙間Ｇ３を塞ぐために、戸当たり側のガイドシュー１５Ａ，１５Ｂを、ほぼ戸当たりゴム３６Ａ，３６Ｂの先端位置に接近する位置まで乗場ドア
７Ａ，７Ｂの戸当たり側から突出させている。 By the way, the landing doors 7A and 7B according to the present embodiment are so-called two-door central opening landing doors that open and close the doorway 4 laterally from the center to both sides. Are provided with door stop rubbers 36A and 36B, respectively, so that the landing doors 7A and 7B directly abut against each other and the collision sound and the door are not damaged. By providing the door stop rubbers 36A and 36B, the door stop side of the opposite landing doors 7A and 7B is provided with a gap G3 as shown in FIGS. 7A and 7B are prevented from colliding. And in order to block this gap G3, the door shoe side guide shoes 15A, 15B are protruded from the door contact side of the landing doors 7A, 7B to a position approaching the tip end position of the door stop rubbers 36A, 36B.

上記のようにガイドシュー１５Ａ，１５Ｂを形成することにより、乗場ドア７Ａ，７Ｂと敷居１１との間は塞がれる。しかし、ガイドシュー１５Ａ，１５Ｂを含む第３の遮煙体１９Ａ，１９Ｂは、敷居溝１１Ｇの幅によって決められるので、乗場ドア７Ａ，７Ｂの厚さよりも小さく形成せざるを得ない。その結果、戸当たりゴム３６Ａ，３６Ｂとガイドシュー１５Ａ，１５Ｂとの間に生じた隙間から、図１２〜図１４の（１）〜（３）で示すように、僅かではあるが昇降路２内の煙が侵入し、乗場ドア７Ａ，７Ｂの戸当たり側の隙間Ｇ３を経由して乗場３側に流入することがある。また、戸当たりゴム３６Ａ，３６Ｂの上端からも、図１２の（４）に示すように、隙間Ｇ３に煙が侵入して乗場３側に流入することがある。 By forming the guide shoes 15A and 15B as described above, the space between the landing doors 7A and 7B and the sill 11 is closed. However, since the third smoke shields 19A and 19B including the guide shoes 15A and 15B are determined by the width of the threshold groove 11G, they must be formed smaller than the thickness of the landing doors 7A and 7B. As a result, from the gap formed between the door stop rubbers 36A and 36B and the guide shoes 15A and 15B, as shown in FIGS. May intrude and flow into the landing 3 side via the gap G3 on the door contact side of the landing doors 7A and 7B. Also, as shown in FIG. 12 (4), smoke may enter the gap G3 from the upper ends of the door stop rubbers 36A and 36B and flow into the landing 3 side.

このような僅かな煙の貫流をも低減させるために、本実施の形態によれば、乗場ドア
７Ａ，７Ｂの戸当たり側の上下部に第４の遮煙体である上部隙間塞ぎ手段３７Ａと下部隙間塞ぎ手段３７Ｂを設けたのである。これら上下部隙間塞ぎ手段３７Ａ，３７Ｂは、夫々一端が前記戸当たりゴム３６Ａ，３６Ｂとの間に隙間が生じないように接する塞ぎ体38Ａ，３８Ｂを備えている。これら塞ぎ体３８Ａ,３８Ｂは、前記戸当たりゴム３６Ａ,３６Ｂと同様な材料で形成されており、塞ぎ体３８Ａは乗場ドア７Ａの戸当たり側に、塞ぎ体
３８Ｂは乗場ドア７Ｂの戸当たり側に、ドア開閉動作時に互いに摺動できるように上下で接触するように取付けられている。これら塞ぎ体３８Ａ，３８Ｂの突出長さ（ドア移動方向の長さ）は、ドア閉じ時に、戸当たりゴム３６Ａ，３６Ｂより先に対向する乗場ドア
７Ａ，７Ｂの戸当たり側に当接して戸当たりゴム３６Ａ，３６Ｂ間に隙間が生じないように、ドア閉じ時における前記乗場ドア７Ａ，７Ｂの戸当たり側の隙間Ｇ３よりも短くしている。 In order to reduce such a slight flow of smoke, according to the present embodiment, the upper gap closing means 37A, which is a fourth smoke shield, is provided on the upper and lower sides of the landing doors 7A, 7B. The lower gap closing means 37B is provided. Each of the upper and lower gap closing means 37A and 37B includes closing bodies 38A and 38B that are in contact with each other so that no gap is formed between the one end and the door stop rubbers 36A and 36B. These closing bodies 38A, 38B are formed of the same material as the door stop rubbers 36A, 36B. The closing body 38A is on the door stop side of the landing door 7A, and the closing body 38B is on the door stop side of the landing door 7B. The doors are attached so as to be in contact with each other at the time of opening and closing the door. The projecting lengths (lengths in the door movement direction) of the closing bodies 38A and 38B are in contact with the door-stop side of the landing doors 7A and 7B facing the door-contact rubbers 36A and 36B when the door is closed. In order not to generate a gap between the rubbers 36A and 36B, the gap G3 is shorter than the door contact gap G3 of the landing doors 7A and 7B when the door is closed.

以上のように、乗場ドア７Ａ，７Ｂの戸当たり側の上下部に上部隙間塞ぎ手段３７Ａと下部隙間塞ぎ手段３７Ｂを設けることにより、戸当たりゴム３６Ａ，３６Ｂの上下端における乗場ドア７Ａ，７Ｂの下端との隙間から侵入しようとする煙は、図１２〜図１４に
（１）で示す位置及び図１３の（４）で示す位置までは侵入するが、それ以上は戸当たりゴム３６Ａ，３６Ｂに接する塞ぎ体３８Ａ，３８Ｂによって阻止されるので、隙間Ｇ３を通って乗場３に流入することはない。 As described above, by providing the upper gap closing means 37A and the lower gap closing means 37B at the upper and lower portions of the landing doors 7A and 7B, the landing doors 7A and 7B at the upper and lower ends of the door stop rubbers 36A and 36B are provided. Smoke that tries to enter from the gap with the lower end enters the position shown by (1) in FIGS. 12 to 14 and the position shown by (4) in FIG. 13, but beyond that, it enters the door stop rubbers 36A and 36B. Since the blocking bodies 38A and 38B are in contact with each other, they do not flow into the landing 3 through the gap G3.

ところで、前記塞ぎ体３８Ａ，３８Ｂは、戸当たりゴム３６Ａ，３６Ｂと同様な材料で形成されたものであるが、これら塞ぎ体３８Ａ，３８Ｂを戸当たりゴム３６Ａ，３６Ｂよりも柔らかく圧縮性のある材料で形成すれば、２つの塞ぎ体３８Ａ，３８Ｂのいずれか一方のみを設けることで煙の貫流を防止することができる。 By the way, the closing bodies 38A and 38B are made of the same material as the door stop rubbers 36A and 36B. However, the closing bodies 38A and 38B are softer and more compressible than the door stop rubbers 36A and 36B. In this case, it is possible to prevent the smoke from flowing by providing only one of the two blocking bodies 38A and 38B.

即ち、塞ぎ体の長さを、ドア閉じ時における前記隙間Ｇ３よりも長くし、これを設置するのである。このような塞ぎ体を設置することにより、ドア閉じ時に、戸当たりゴム36Ａ，３６Ｂが当接しても、塞ぎ体は隙間Ｇ３内で圧縮されて縮む。したがって、塞ぎ体が障害となって戸当たりゴム３６Ａ，３６Ｂの当接が妨げられることはなく、煙の貫流を遮断することができる。 That is, the length of the closing body is made longer than the gap G3 when the door is closed, and this is installed. By installing such a closing body, even when the door stop rubbers 36A and 36B come into contact with each other when the door is closed, the closing body is compressed and contracted in the gap G3. Therefore, the blocking body does not obstruct the contact of the door stop rubbers 36A and 36B, and the flow of smoke can be blocked.

図１６は、図３に示す滑り部材２２の乗場ドア７Ａ，７Ｂの上縁部への支持構造を示す第二の実施の形態である。 FIG. 16 is a second embodiment showing a structure for supporting the sliding member 22 shown in FIG. 3 on the upper edge portions of the landing doors 7A and 7B.

即ち、乗場ドア７Ａ，７Ｂに固定する滑り部材３９の上下方向寸法を大きくし、下方のみばね材等の保持具２３Ａで挟み込むことにより、保持具２３Ａに対する抜き差し方向をドア移動方向と上方向にも行えるようにしたものである。それ以外の構成は、第一の実施の形態と同じである。 That is, by increasing the vertical dimension of the sliding member 39 fixed to the landing doors 7A and 7B and sandwiching the sliding member 39 only by the lower portion with a holding tool 23A such as a spring material, the insertion / removal direction with respect to the holding tool 23A can be changed in the door moving direction and the upward direction. It is something that can be done. Other configurations are the same as those in the first embodiment.

また図２３は、図３に示す乗場ドア７Ａ，７Ｂの上縁部に設けた滑り部材２２を、板ばね２０の自由端に取付けた滑り部材２１よりも硬い材質５５で構成することにより、常に滑り部材２１が磨耗する構成としたものを示している。この構成により、乗場ドア７Ａ,７Ｂに取り付けた滑り部材５５Ａ，５５Ｂは磨耗しないため交換不要とすることが出来る。また、この構成においては前述したように乗場ドア７Ａ，７Ｂに取り付けた滑り部材
５５は交換不要のため、着脱可能な構成とする必要はなく、ドアへの取付けをビスなどで行うなど、構造を簡略化でき、保守性も向上する。 FIG. 23 shows that the sliding member 22 provided on the upper edge of the landing doors 7A and 7B shown in FIG. 3 is always made of a material 55 that is harder than the sliding member 21 attached to the free end of the leaf spring 20. A configuration in which the sliding member 21 is worn is shown. With this configuration, the sliding members 55A and 55B attached to the landing doors 7A and 7B are not worn out, so that replacement is unnecessary. Further, in this configuration, as described above, the sliding member 55 attached to the landing doors 7A and 7B does not need to be replaced, so there is no need to make it a detachable configuration. It can be simplified and maintainability is improved.

図２４，図２５では、図６，図７に示す乗場ドア７Ａ，７Ｂの戸袋側端と三方枠８の縦枠９Ａ（９Ｂ）の戸袋側端との間に設けられた第１〜第３の塞ぎ部材２７〜２９において、塞ぎ部材２７，２８が、下端で敷居１１の上面や床面に接する摺動材５７Ａ，５７Ｂを板バネ５８Ａ〜５８Ｆにより着脱可能に取り付けられている。この構成によれば、図７のようにゴム板３０Ａ，３０Ｂを、塞ぎ部材２７，２８より下方に突出させる必要がない。このため、縦枠９Ａとの隙間Ｇ１を塞ぐゴム板は５９Ａに示すように縦枠９Ａとの接触部付近のみでよい。なお、図２４に示すように、縦枠９に折り返し部６０を設けることにより、縦枠９の塞ぎ部材２９は不要とできる。また、同図に示すように、ゴム板は必ずしも縦枠９と塞ぎ部材２９の両方に設けなくてもよく、ゴム板５９は縦枠の折り返し部６０，塞ぎ部材２９のどちらにつけても同様に遮煙効果が得られる。 24 and FIG. 25, first to third doors provided between the door side end of the landing doors 7A and 7B shown in FIG. 6 and FIG. 7 and the door side end of the vertical frame 9A (9B) of the three-way frame 8 are shown. In the closing members 27 to 29, the closing members 27 and 28 are detachably attached to the sliding members 57 A and 57 B that come into contact with the upper surface and floor surface of the sill 11 at the lower ends by leaf springs 58 A to 58 F. According to this configuration, it is not necessary to project the rubber plates 30A and 30B downward from the closing members 27 and 28 as shown in FIG. For this reason, the rubber plate that closes the gap G1 with the vertical frame 9A only needs to be in the vicinity of the contact portion with the vertical frame 9A as indicated by 59A. In addition, as shown in FIG. 24, the closing member 29 of the vertical frame 9 can be made unnecessary by providing the folded portion 60 in the vertical frame 9. Further, as shown in the figure, the rubber plate is not necessarily provided on both the vertical frame 9 and the closing member 29, and the rubber plate 59 is similarly attached to either the folded portion 60 or the closing member 29 of the vertical frame. A smoke shielding effect is obtained.

図１７は、乗場ドア７Ａ，７Ｂの下縁部と前記敷居１１との隙間Ｇ２を塞ぐ第３の遮煙体１９Ａ，１９Ｂを示す第三の実施の形態である。 FIG. 17 is a third embodiment showing third smoke shields 19A and 19B that block the gap G2 between the lower edge portions of the landing doors 7A and 7B and the sill 11.

この実施の形態においては、乗場ドア７Ａ，７Ｂの下縁部に取付け金具４０Ａを固定し、この取付け金具４０Ａに対して上下方向に調整可能に取付け金具４０Ｂを支持し、この取付け金具４０Ｂの敷居１１の頂面と対向する位置にゴム板４１を固定し、このゴム板
４１の敷居１１の頂面と対向する面に滑り材４２を固定して第３の遮煙体１９Ａ，１９Ｂを構成したのである。尚、前記取付け金具４０Ｂはドア幅全長に亘る長さを有し、両乗場ドア７Ａ，７Ｂの戸当たり側で互いに当接するように構成されている。また、取付け金具４０Ｂにも遮煙機能を持たせることから、乗場ドア７Ａ，７Ｂとの間に隙間が生じないように、モケットシート等の塞ぎ体４３を取付け金具４０Ｂあるいは乗場ドア７Ａ，７Ｂに固定している。 In this embodiment, the mounting bracket 40A is fixed to the lower edges of the landing doors 7A and 7B, and the mounting bracket 40B is supported so as to be adjustable in the vertical direction with respect to the mounting bracket 40A. The rubber plate 41 is fixed at a position opposite to the top surface of the 11 and the sliding material 42 is fixed to the surface of the rubber plate 41 facing the top surface of the sill 11 to constitute the third smoke shields 19A and 19B. It is. The mounting bracket 40B has a length that extends over the entire length of the door, and is configured to abut against each other on the door contact side of both landing doors 7A and 7B. Further, since the mounting bracket 40B is also provided with a smoke shielding function, a closing body 43 such as a moquette seat is attached to the mounting bracket 40B or the landing doors 7A and 7B so that no gap is formed between the mounting bracket 40B and the landing doors 7A and 7B. It is fixed.

図１８及び図１９は、戸当たりゴム３６Ａ，３６Ｂの上下端と乗場ドア７Ａ，７Ｂの幅方向の僅かな隙間からの煙の貫流を防止する第四の実施の形態を示すものである。 FIG. 18 and FIG. 19 show a fourth embodiment for preventing smoke from flowing from the upper and lower ends of the door stop rubbers 36A, 36B and a slight gap in the width direction of the landing doors 7A, 7B.

即ち、乗場ドア７Ａ，７Ｂに設けた戸当たりゴム３６Ａ，３６Ｂに接触させてガイドシュー１５Ａ，１５Ｂを取付けることで、戸当たりゴム３６Ａ，３６Ｂの下端と乗場ドア
７Ａ，７Ｂの幅方向との間に隙間が発生することはなく、また敷居１１と乗場ドア７Ａ，７Ｂの下端との間は、ガイドシュー１５Ａ，１５Ｂ及び第３の遮煙体１９Ａ，１９Ｂを敷居溝１１Ｇ内にて摺動させることにより塞いでいるので、煙の貫流を防ぐことができる。 That is, by attaching the guide shoes 15A and 15B in contact with the door stop rubbers 36A and 36B provided on the landing doors 7A and 7B, between the lower ends of the door stop rubbers 36A and 36B and the width direction of the landing doors 7A and 7B. The guide shoes 15A and 15B and the third smoke shields 19A and 19B are slid in the sill groove 11G between the sill 11 and the lower ends of the landing doors 7A and 7B. Since it is blocked by this, the flow of smoke can be prevented.

以上の実施の形態においては、乗場ドア７Ａ，７Ｂの上縁部が乗降口４を区画する区画部材である三方枠８の上枠１０に対向する構成である。しかし乗場３側の意匠によっては、三方枠８の上枠１０が存在せず、変わりに幕板が設けられ、乗場ドア７Ａ，７Ｂのドア面が、この幕板と面一に設置される場合がある。 In the above embodiment, the upper edge portions of the landing doors 7A and 7B are opposed to the upper frame 10 of the three-way frame 8 which is a partition member that partitions the entrance / exit 4. However, depending on the design on the landing 3 side, the upper frame 10 of the three-way frame 8 does not exist, and instead a curtain is provided, and the door surfaces of the landing doors 7A and 7B are installed flush with the curtain. There is.

図２０は、乗場ドア７Ａ，７Ｂのドア面が幕板と面一に設置される第五の実施の形態を示すものである。 FIG. 20 shows a fifth embodiment in which the door surfaces of the landing doors 7A and 7B are installed flush with the curtain plate.

即ち、三方枠の上枠に代わって設けられた幕板４４とドア面が面一となるように乗場ドア７Ａ，７Ｂが配置されている。これら乗場ドア７Ａ，７Ｂの頂部は前記幕板４４と微小隙間を介して対向しているために、そこからハンガー１２Ａ，１２Ｂを吊ることができない。そこで、乗場ドア７Ａ，７Ｂの上部の側面側にドア幅と同じ長さを有するハンガーブラケット４５を取付け、このハンガーブラケット４５からハンガー１２Ａ，１２Ｂを吊るようにしている。そして、前記幕板４４の裏側（昇降路側）の前記ハンガーブラケット
４５に対向する位置に、ビス等の周知の固定手段によって板ばね２０を着脱可能に固定し、この板ばね２０の自由端部を前記ハンガーブラケット４５に摺動可能に圧接させている。勿論、板ばね２０の自由端部には前記ハンガーブラケット４５との摺動を円滑にするために滑り部材２１が取付けられている。また、ハンガーブラケット４５の前記板ばね２０が摺動圧接する位置には、図３に示すように、滑り部材２２がばね材等の保持具２３Ａ，２３Ｂで挟むようにして着脱可能に支持されている。 That is, the landing doors 7A and 7B are arranged so that the door surface is flush with the curtain plate 44 provided in place of the upper frame of the three-way frame. Since the tops of these landing doors 7A and 7B are opposed to the curtain plate 44 through a minute gap, the hangers 12A and 12B cannot be hung there. Accordingly, a hanger bracket 45 having the same length as the door width is attached to the upper side surface of the landing doors 7A and 7B, and the hangers 12A and 12B are suspended from the hanger bracket 45. Then, the leaf spring 20 is detachably fixed by a known fixing means such as a screw at a position facing the hanger bracket 45 on the back side (the hoistway side) of the curtain plate 44, and the free end portion of the leaf spring 20 is fixed. The hanger bracket 45 is slidably pressed. Of course, the sliding member 21 is attached to the free end portion of the leaf spring 20 in order to make the sliding with the hanger bracket 45 smooth. Further, as shown in FIG. 3, the sliding member 22 is detachably supported at a position where the leaf spring 20 of the hanger bracket 45 is in sliding contact with the hanger bracket 45 so as to be sandwiched between holders 23A and 23B such as spring materials.

以上の各実施の形態は、乗場ドアを乗降口４の中央から両側に開閉する方式であるが、乗場ドアを乗降口の一方側から他方側へ片開きする乗場ドアも存在する。 Each of the above embodiments is a system in which the landing door is opened and closed on both sides from the center of the entrance / exit 4, but there is also a landing door in which the landing door is opened from one side to the other side.

以下、第六の実施の形態として片開き乗場ドアの遮煙構成を図２１及び図２２に基づいて説明する。 Hereinafter, as a sixth embodiment, a smoke shielding structure of a single-open landing door will be described with reference to FIGS. 21 and 22.

図２１及び図２２において、第一の実施の形態と基本的に異なる構成は、複数の乗場ドア７Ａ，７Ｂがドア閉じ時に隣接する縁部を互いに重ねていることであり、その他の構成についてはほぼ同じであるので、説明は省略する。 21 and 22, the fundamentally different configuration from the first embodiment is that a plurality of landing doors 7A and 7B overlap adjacent edges when the door is closed. Since it is substantially the same, description is abbreviate | omitted.

隣接する乗場ドア７Ａの戸袋側と乗場ドア７Ｂの戸当たり側には、第５の遮煙体４７が設けられている。この第５の遮煙体４７は、第１〜第３の塞ぎ部材４８〜５０で構成されている。第１の塞ぎ部材４８は、ドアの全高に亘る長さを有し、乗場ドア７Ａの戸袋側端に支持され、ドアの高さ方向に沿って上下方向に調整可能にボルト等で固定された断面Ｌ字型をなしている。第２塞ぎ部材４９もドアの全高に亘る長さを有し、前記第１塞ぎ部材４８にドア移動方向に調整可能にボルト等で支持され、乗場ドア７Ｂ側に突出する垂直面を有する断面Ｌ字型をなしている。そして第３の塞ぎ部材５０は、第１，第２の塞ぎ部材４８，４９と同じ長さを有し、乗場ドア７Ｂの戸袋側端にボルト等で支持され、前記第２塞ぎ部材４９の垂直面と対向する垂直面を有する断面Ｌ字型をなしている。尚、これら第１〜第３の塞ぎ部材４８〜５０は、夫々直に接触して騒音や振動が生じないようにするために、ゴム板５１Ａ〜５１Ｃを介在させている。これらの中でゴム板５１Ａ，５１Ｂは、その下端を敷居（図示せず）の上面や床面（図示せず）に接するように、第１，第２の塞ぎ部材４８，４９の下端から下方に突出させている。 A fifth smoke shield 47 is provided on the door pocket side of the adjacent landing door 7A and the door stop side of the landing door 7B. The fifth smoke shield 47 includes first to third blocking members 48 to 50. The first closing member 48 has a length that extends over the entire height of the door, is supported by the door pocket side end of the landing door 7A, and is fixed with a bolt or the like so as to be adjustable in the vertical direction along the height direction of the door. It has an L-shaped cross section. The second closing member 49 also has a length extending over the entire height of the door, and is a cross section L having a vertical surface that is supported by the first closing member 48 with a bolt or the like so as to be adjustable in the door moving direction and protrudes toward the landing door 7B. It has a letter shape. The third closing member 50 has the same length as the first and second closing members 48 and 49, is supported by a door or the like on the door side of the landing door 7 B, and is perpendicular to the second closing member 49. It has an L-shaped cross section having a vertical surface facing the surface. The first to third closing members 48 to 50 are provided with rubber plates 51A to 51C in order to directly contact each other and prevent noise and vibration. Among these, the rubber plates 51A and 51B are downward from the lower ends of the first and second closing members 48 and 49 so that the lower ends thereof are in contact with the upper surface and floor surface (not shown) of the sill (not shown). Protruding.

上記構成において、ドア開き時に、乗場ドア７Ａに支持させた第２の塞ぎ部材４９の乗場ドア７Ｂ側へ突出した部分が、乗場ドア７Ｂの戸袋側７Ｅに接触しないように、乗場ドア７Ｂの戸袋側７の折り返し寸法Ｌ２を、戸当たり側の折り返し寸法Ｌ１よりも小さくしている。さらに、乗場ドア８Ａの戸当たり側には、ドア閉じ時に、三方枠５２の戸当たり側縦枠５３Ａの全高に亘って取付けた戸当たりゴム５５と接するように、ドア全高に亘って遮煙ゴム５６が取付けられている。その他、三方枠５２の戸袋側縦枠５３Ｂや上枠５４と各ドアとの遮煙構成は前記実施の形態と基本的に同じである。 In the above configuration, when the door is opened, the door of the landing door 7B is such that the portion of the second closing member 49 supported by the landing door 7A that protrudes toward the landing door 7B does not contact the door side 7E of the landing door 7B. The folding dimension L2 on the side 7 is smaller than the folding dimension L1 on the door stop side. Further, on the door stop side of the landing door 8A, when the door is closed, the smoke-insulating rubber is provided over the entire height of the door so as to come into contact with the door stop rubber 55 attached over the entire height of the door stop-side vertical frame 53A of the three-way frame 52. 56 is attached. In addition, the smoke-insulating configuration of the door frame side vertical frame 53B or the upper frame 54 of the three-way frame 52 and each door is basically the same as that of the above embodiment.

本実施の形態によれば、片開き乗場ドアにおいても、第１の実施の形態と同じように、火災時における昇降路と乗場間の煙の貫流を防止できるのは勿論のこと、施工及び保守点検を簡単に行うことができる。 According to the present embodiment, in a single-opening landing door, as in the first embodiment, it is possible to prevent smoke from flowing between the hoistway and the landing during a fire, as well as construction and maintenance.
