Description

本発明はエレベータのドア安全装置に関し、特に、戸開時にエレベータの出入口を開閉するスライドドアとこのスライドドアと重合関係にあって且つ戸開動作時に該スライドドアと相対移動する壁体との間に万が一乗客の衣服や手指等の異物が引き込まれたときに少なくともスライドドアを減速させる装置に関する。   The present invention relates to an elevator door safety device, and in particular, between a sliding door that opens and closes an elevator door when the door is opened and a wall that is in a superimposed relationship with the sliding door and moves relative to the sliding door when the door is opened. The present invention relates to a device that decelerates at least a sliding door when a foreign object such as clothes or fingers of a passenger is drawn.

エレベータの出入口を開閉するスライドドアはドア駆動装置により駆動されて出入口を開閉するが、戸開動作中に例えば戸袋内に万が一異物が引き込まれたときに少なくともスライドドアを減速させ、異物のさらなる引き込まれを防止するために様々なドア安全装置が提案されている。   The sliding door that opens and closes the entrance / exit of the elevator is driven by a door drive device to open / close the entrance / exit, but during the door opening operation, for example, if a foreign object is drawn into the door pocket, at least the sliding door is decelerated to further draw in the foreign object. Various door safety devices have been proposed to prevent this.

具体的には、戸袋内へ異物が引き込まれたことを検知する例えば光電スイッチやマイクロスイッチ等の検出スイッチを戸袋の入口付近に設け、戸開動作中にその検出スイッチが検出作動したことを条件としてドア駆動装置の戸開動作を減速または停止させる等の制御を行ない、異物のさらなる引き込まれを防止することが従来から行われており、例えば特許文献１〜３に記載されている。
特開２００１−８９０５４号公報 特開２００２−３４８０７５号公報 特開２００４−１８２６１号公報 Specifically, for example, a detection switch such as a photoelectric switch or a micro switch that detects that a foreign object has been drawn into the door pocket is provided near the entrance of the door pocket, and the detection switch is activated during the door opening operation. For example, Patent Documents 1 to 3 disclose that the door opening operation of the door driving device is controlled to decelerate or stop and prevent further foreign objects from being drawn.
JP 2001-89054 A JP 2002-348075 A JP 2004-18261 A

上記従来の技術では、戸開動作中に戸袋内へ異物が引き込まれたことを検出スイッチにて検出した上で、その検出信号をドア駆動装置を制御する制御装置に電気配線を介して取り込み、ソフトウェア上の処理を経てドア駆動装置の駆動を停止することとなる。したがって、異物の引き込まれを防止するためには多くの機器が正常に動作する必要があり、動作の信頼性に欠ける。また、異物が引き込まれてからドア駆動装置の駆動を停止させるまでに若干の時間を要する上に、ドア駆動装置の駆動を停止させた後もスライドドアがその慣性にて戸開方向に移動するため、異物がさらに引き込まれて手指等の異物への負荷が大きくなる恐れがある。   In the above-described conventional technology, the detection switch detects that a foreign object has been drawn into the door pocket during the door opening operation, and then takes the detection signal into the control device that controls the door driving device via the electrical wiring, The drive of the door drive device is stopped through processing on software. Therefore, in order to prevent foreign objects from being drawn in, many devices need to operate normally, and operation reliability is lacking. In addition, it takes some time to stop the drive of the door drive device after the foreign object is drawn, and the slide door moves in the door opening direction due to its inertia even after the drive of the door drive device is stopped. For this reason, there is a possibility that the foreign object is further drawn and the load on the foreign object such as a finger is increased.

本発明は上記の課題に鑑み、引き込まれによる異物への負荷をより軽減するとともに、信頼性の向上を図ったエレベータのドア安全装置を提供することを目的としている。   SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide an elevator door safety device that further reduces the load on foreign objects caused by being pulled in and improves reliability.

請求項１に記載の発明は、ドア駆動装置により駆動されて出入口を左右方向に開閉するスライドドアとそのスライドドアと重合関係にあって且つ戸開動作時にスライドドアと相対移動する壁体との間の隙間に異物が引き込まれた際に、少なくともスライドドアを減速させるエレベータのドア安全装置であって、上記壁体の戸閉方向側端面のうち少なくともスライドドアと近接する部位を引き込まれ部として戸開閉方向に変位可能とするとともに、その引き込まれ部の変位に連動するブレーキシューをスライドドアの表側壁面に対向配置し、異物に押圧されて引き込まれ部が戸開方向に変位したことに連動してブレーキシューをスライドドアの表側壁面に押し付けることにより、スライドドアに制動をかけるようになっていることを特徴としている。   According to the first aspect of the present invention, there is provided a sliding door that is driven by a door driving device to open and close the entrance / exit in the left-right direction, and a wall body that is in a superimposed relationship with the sliding door and that moves relative to the sliding door when the door is opened. It is an elevator door safety device that decelerates at least the sliding door when a foreign object is drawn into the gap between them, and at least a portion close to the sliding door is drawn into the door closing direction side end surface of the wall body. Displaceable in the door opening and closing direction, and a brake shoe that is linked to the displacement of the retracted part is placed opposite the front side wall surface of the slide door, linked to the fact that the retracted part is displaced in the door opening direction when pressed by a foreign object The brake shoe is pressed against the front side wall surface of the slide door to brake the slide door. That.

ここで、より具体的には例えば請求項５に記載の発明のように、引き込まれ部を常時戸閉方向に付勢する付勢手段と、その付勢力に抗して揺動パネルを定常静止位置に静止させるストッパーと、を設けるものとする。   More specifically, for example, as in the invention described in claim 5, the urging means for constantly urging the retracted portion in the door closing direction, and the swinging panel against the urging force is stationary stationary. And a stopper that is stationary at the position.

したがって、少なくとも請求項１に記載の発明では、万が一上記隙間に異物が引き込まれると、引き込まれ部がその異物とともに戸開方向に変位することで異物への負荷を軽減しつつ、その変位に連動してブレーキシューが直接的にスライドドアに制動をかけて少なくともスライドドアを減速する。また、その機構を単純な機械要素にて実現でき、異物が上記隙間に引き込まれたときには確実に動作して異物のさらなる引き込まれを防止することができる。   Therefore, in at least the first aspect of the invention, if a foreign object is drawn into the gap, the drawn-in part is displaced in the door opening direction together with the foreign object, thereby reducing the load on the foreign object and interlocking with the displacement. The brake shoe directly brakes the sliding door to decelerate at least the sliding door. In addition, the mechanism can be realized by a simple machine element, and when foreign matter is drawn into the gap, it can operate reliably and prevent further foreign matter from being drawn.

より望ましくは、請求項２に記載の発明のように、ブレーキシューが引き込まれ部よりも戸開方向側に位置するように引き込まれ部と連結され、ブレーキシューの戸開方向への変位に応じてブレーキシューをスライドドアに向かって押し出すように案内するガイド部材を設けるものとすると、ドア駆動装置の戸開力がブレーキシューをより強くスライドドアに押し付ける方向に働くため、スライドドアに対するブレーキシューの制動力がより強大となる。   More preferably, as in the invention described in claim 2, the brake shoe is pulled in and connected to the retracted portion so as to be positioned on the door opening direction side of the portion, and the brake shoe is adapted to the displacement in the door opening direction. If the guide member that guides the brake shoe to push out toward the sliding door is provided, the door opening force of the door drive device works in the direction of pressing the brake shoe more strongly against the sliding door. The braking force becomes stronger.

さらに具体的には、請求項３に記載の発明のように、ガイド部材はブレーキシューの反スライドドア側に設置されているとともに戸開方向に向かってスライドドアに近接するように傾斜したガイド面を有していて、ブレーキシューが引き込まれ部とともに戸開方向に変位したときに、ガイド面とスライドドアの表側壁面との間にブレーキシューを挟み込むようにすると、万が一上記隙間に異物が引き込まれたときにガイド面とスライドドアの表側壁面との間にブレーキシューがくさびの如く押し込まれるとともに、上記戸開力はブレーキシューが一段と押し込まれる方向に作用して強大な制動力が得られる。   More specifically, as in the invention described in claim 3, the guide member is installed on the side opposite to the sliding door of the brake shoe and is inclined so as to approach the sliding door toward the door opening direction. If the brake shoe is sandwiched between the guide surface and the front side wall surface of the sliding door when the brake shoe is retracted and displaced in the door opening direction together with the part, foreign matter will be drawn into the gap. When the brake shoe is pushed like a wedge between the guide surface and the front side wall surface of the slide door, the door opening force acts in the direction in which the brake shoe is pushed further and a strong braking force is obtained.

また、請求項４に記載の発明のように、上記引き込まれ部が、壁体の戸閉方向側端面を定常静止位置から鉛直軸心周りに揺動自在な揺動パネルとして分割することで形成されていて、ブレーキシューとして機能する鉛直軸心周りに回転自在なローラが揺動パネルに対してそれ自体の揺動方向と同方向に揺動自在に連結されていると、上記揺動パネルが周囲の意匠との調和を損なわない上に、上記ローラとスライドドアとの接触面積が小さいためスライドドアに上記ローラが押し付けられた痕跡が目立たず、乗客に外観上の違和感を与えないため、外観品質を向上させる上で望ましい。   According to a fourth aspect of the present invention, the drawn-in portion is formed by dividing the end surface of the wall body in the door closing direction as a swing panel that can swing around the vertical axis from the stationary stationary position. If a roller rotatable around a vertical axis that functions as a brake shoe is connected to the swing panel so as to be swingable in the same direction as its own swing, the swing panel is In addition to maintaining harmony with the surrounding design, the contact area between the roller and the sliding door is small, so the traces of pressing the roller against the sliding door are inconspicuous and the passenger will not feel discomfort in appearance. Desirable for improving quality.

さらに望ましくは、請求項６，７に記載の発明のように、上記引き込まれ部が戸開方向に変位したことを検出する検出スイッチを備えていて、戸開動作中にその検出スイッチが検出作動したことを条件としてドア駆動装置の戸開動作を停止するとともに、ドア駆動装置の戸開動作を停止した後にドア駆動装置が戸閉動作するようにすると、異物が万が一上記隙間に引き込まれて引き込まれ部が戸開方向に変位した時にマイクロスイッチが検出作動し、ブレーキシューによりスライドドアに制動をかけるのに加えてドア駆動装置によるスライドドアの戸開方向の駆動を停止することとなり、より安全性が高まる。その上、戸開方向の駆動を停止した後にドア駆動装置が戸閉動作することで、戸閉動作するスライドドアにより異物が上記隙間から離脱する方向に引かれることとなるので、さらに安全性が高まる。   More preferably, as in the inventions described in claims 6 and 7, a detection switch for detecting that the retracted portion has been displaced in the door opening direction is provided, and the detection switch operates during the door opening operation. If the door drive operation of the door drive device is stopped after the door drive operation of the door drive device is stopped on the condition that the door drive device is closed after the door drive operation is stopped, the foreign object should be drawn into the gap. The micro-switch is detected and actuated when this part is displaced in the door opening direction, and in addition to braking the sliding door with the brake shoe, the door driving device stops driving the door in the door opening direction. Increases nature. In addition, since the door drive device performs the door closing operation after stopping the drive in the door opening direction, foreign matter is pulled away from the gap by the sliding door that performs the door closing operation. Rise.

請求項１に記載の発明によれば、引き込まれ部がその異物とともに戸開方向に変位することで異物への負荷を軽減する上に、その引き込まれ部の変位に連動してブレーキシューがスライドドアに直接的に制動をかけてスライドドアを少なくとも減速するため、異物のさらなる引き込まれを効果的に防止して引き込まれによる異物への負荷をより軽減することができるとともに、ドア安全装置を単純な機械要素にて構成することが可能であるため動作の確実性が高く、信頼性の向上が図れる。   According to the first aspect of the present invention, the retracted portion is displaced in the door opening direction together with the foreign matter to reduce the load on the foreign matter, and the brake shoe slides in conjunction with the displacement of the retracted portion. Because the door is braked directly and the sliding door is at least decelerated, it is possible to effectively prevent further foreign objects from being pulled in, thereby reducing the load on the foreign objects and pulling in the door safety device. Since it can be configured with various machine elements, the reliability of the operation is high and the reliability can be improved.

図１〜３は本発明のより具体的な実施の形態としてエレベータのかごに設けられた出入口を示す図であって、図１はその正面図、図２は図１におけるＡ−Ａ断面図、図３は図２におけるＢ−Ｂ断面図である。   1-3 is a figure which shows the entrance / exit provided in the elevator car as more concrete embodiment of this invention, Comprising: FIG. 1 is the front view, FIG. 2 is AA sectional drawing in FIG. 3 is a cross-sectional view taken along the line BB in FIG.

図１に示すように、エレベータのかごに設けられたかご側出入口１は、左右方向に所定の間隔をあけて対向配置された左右の壁体たる縦枠２と、それらの縦枠２の上部を連結する上枠３と、から形成されていて、二枚のスライドドア４により開閉される。戸開閉形式はいわゆる二枚両開きタイプで、かご側出入口１の全閉時にはかご側出入口１の略中央位置にて左右のスライドドア４の先端面同士が突き合わされていて、戸開動作時にドア制御部５の指令に基づいてスライドドア４の上方に設けられているドア駆動装置６により左右のスライドドア４が駆動され、それぞれが離間する方向にスライド変位することでかご側出入口１が開放される。その開閉機構上、左右のスライドドア４とこのスライドドア４と重合関係にあって且つ戸開動作時に左右のスライドドア４と相対変位する左右の縦枠２との間には、図２に示すようにスライドドア４の厚さ方向で所定の隙間Ｇが設けられている。   As shown in FIG. 1, a car side doorway 1 provided in an elevator car includes a vertical frame 2 that is a left and right wall body arranged to face each other at a predetermined interval in the left-right direction, and upper portions of the vertical frames 2. , And is opened and closed by two slide doors 4. The door opening / closing type is a so-called two-sheet double-opening type. When the car side doorway 1 is fully closed, the front end surfaces of the left and right sliding doors 4 are abutted at the approximate center position of the car side doorway 1 and the door is controlled when the door is opened. The left and right sliding doors 4 are driven by a door driving device 6 provided above the sliding door 4 based on a command from the unit 5, and the car side doorway 1 is opened by slidably displacing each in the direction of separation. . 2 between the left and right sliding doors 4 and the left and right vertical frames 2 that are in a superposed relationship with the sliding doors 4 and that are displaced relative to the left and right sliding doors 4 when the door is opened. Thus, a predetermined gap G is provided in the thickness direction of the slide door 4.

縦枠２は袖壁パネル７と揺動パネル８から構成されていて、揺動パネル８は、縦枠２の戸閉方向側端面を構成するとともに、鉛直な揺動軸８ａを中心として袖壁パネル７に揺動自在に連結されている。また、図２および図３に示すように、揺動パネル８にはブレーキシューたるゴムローラ９が揺動パネル８の戸開方向側でスライドドア４のうち表側壁面４ａの上部に対向するように揺動アーム１０を介して連結されている。より具体的には、揺動アーム１０の一端が揺動パネル８に鉛直な揺動軸１０ａを中心として揺動自在に軸着されているとともに、揺動アーム１０の他端にゴムローラ９が鉛直な回転軸９ａを中心に回転自在に軸着されている。ゴムローラ９の反スライドドア側にはガイド部材１１が袖壁パネル７の裏面から突出するように設けられていて、後述するように揺動パネル８が揺動したときには、それに連動してゴムローラ９がガイド部材１１のうち戸開方向側に向かってスライドドア４に近接するように傾斜したガイド面１１ａに沿って変位する。したがって、ガイド部材１１はゴムローラ９の戸開方向への変位に応じてゴムローラ９をスライドドア４の表側壁面４ａに向かって押し出すように案内することとなる。   The vertical frame 2 is composed of a sleeve wall panel 7 and a swing panel 8. The swing panel 8 constitutes a door closing direction side end surface of the vertical frame 2, and a sleeve wall around a vertical swing shaft 8a. The panel 7 is swingably connected. As shown in FIGS. 2 and 3, the swing roller 8 on the swing panel 8 swings so that the rubber roller 9 as a brake shoe faces the upper portion of the front side wall surface 4 a of the slide door 4 on the door opening direction side of the swing panel 8. It is connected via a moving arm 10. More specifically, one end of the swing arm 10 is pivotally mounted on the swing panel 8 so as to be swingable about a vertical swing shaft 10a, and a rubber roller 9 is vertically mounted on the other end of the swing arm 10. A rotating shaft 9a is rotatably mounted around the rotating shaft 9a. A guide member 11 is provided on the anti-sliding door side of the rubber roller 9 so as to protrude from the back surface of the sleeve wall panel 7. When the swing panel 8 swings as will be described later, the rubber roller 9 is interlocked therewith. The guide member 11 is displaced along the guide surface 11a inclined so as to approach the slide door 4 toward the door opening direction. Therefore, the guide member 11 guides the rubber roller 9 so as to push it toward the front side wall surface 4a of the slide door 4 in accordance with the displacement of the rubber roller 9 in the door opening direction.

ガイド部材１１のうち戸閉方向側壁面１１ｂにはマイクロスイッチ１２が揺動パネル８に対向するように検出スイッチとして配置されていて、揺動パネル８が戸開方向に向かって揺動したときにマイクロスイッチ１２が検出作動して実質的にＯＮ作動し、ドア制御部５に検出信号を出力するようになっている。   When the micro switch 12 is arranged as a detection switch on the side wall surface 11b in the door closing direction of the guide member 11 so as to face the swing panel 8, the swing panel 8 swings in the door opening direction. The micro switch 12 is detected and operated to be substantially ON, and a detection signal is output to the door control unit 5.

また、袖壁パネル７および揺動パネル８の裏面同士がいわゆる中折れ式の中折れリンク１３にて連結されていて、引張りばね１４にて中折れリンク１３の屈曲部１３ａと袖壁パネル７とを連結することで中折れリンク１３を拡開させる方向に常時付勢している。すなわち、中折れリンク１３と引張りばね１４が付勢手段として揺動パネル８を戸閉方向に常時付勢していることとなる。さらに、中折れリンク１３の拡開を規制するストッパー１５が袖壁パネル７および揺動パネル８の裏面から突出するようにそれぞれ設けられていて、ストッパー１５が引張りばね１４の付勢力に抗して揺動パネル８をその表側壁面とスライドドア４の表側壁面とが面直角となる定常静止位置に静止させている。ここで、中折れリンク１３は図３に示すように上下方向でほぼ等間隔に複数設けられていて、引張りばね１４およびストッパー１５もそれぞれの中折れリンク１３に対応して複数設けられている。   Further, the back surfaces of the sleeve wall panel 7 and the swing panel 8 are connected to each other by a so-called middle-folded middle-fold link 13, and the bent portion 13 a of the middle-fold link 13 and the sleeve wall panel 7 are connected by a tension spring 14. Are always energized in the direction of expanding the broken link 13. That is, the broken link 13 and the tension spring 14 always urge the swing panel 8 in the door closing direction as urging means. Further, stoppers 15 for restricting the expansion of the broken link 13 are provided so as to protrude from the back surfaces of the sleeve wall panel 7 and the swing panel 8, respectively, and the stopper 15 resists the urging force of the tension spring 14. The swing panel 8 is stationary at a stationary stationary position where the front side wall surface and the front side wall surface of the slide door 4 are perpendicular to each other. Here, as shown in FIG. 3, a plurality of middle broken links 13 are provided at substantially equal intervals in the vertical direction, and a plurality of tension springs 14 and stoppers 15 are also provided corresponding to the respective middle folded links 13.

なお、図１において左側の縦枠２も上述した右側の縦枠２と同様に構成されている。   In FIG. 1, the left vertical frame 2 is configured in the same manner as the right vertical frame 2 described above.

図４は戸開動作時におけるドア制御部５の制御内容を示すフローチャートであって、図５は図２におけるドア安全装置の作動状態を示す図である。   FIG. 4 is a flowchart showing the control contents of the door control unit 5 during the door opening operation, and FIG. 5 is a diagram showing an operating state of the door safety device in FIG.

以上のように構成したエレベータのドア安全装置では、図４に示すように、ドア制御部５の指令に基づいてドア駆動装置６が戸開動作を開始（ステップＳ１）した後、戸開動作中はドア制御部５が常時マイクロスイッチ１２の作動を監視する（ステップＳ２〜Ｓ４）。万が一戸開動作中に手指等の異物１６が隙間Ｇに引き込まれると、図５に示すように、揺動パネル８が異物１６に押圧されて引張りばね１４の付勢力に抗して隙間Ｇを拡開させるように戸開方向に揺動することでマイクロスイッチ１２がＯＮ作動するとともに、揺動パネル８の戸開方向への揺動に連動してゴムローラ９がガイド部材１１のガイド面１１ａに沿って戸開方向に変位し、ガイド部材のガイド面１１ａとスライドドア４の表側壁面４ａとの間にゴムローラ９がくさびの如く挟み込まれてスライドドア４が停止する。すなわち、ゴムローラ９をスライドドア４の表側壁面４ａのうちドア駆動装置５に近接した部位に押し付けることによりスライドドア４に直接的に制動をかけることとなる。   In the elevator door safety device configured as described above, as shown in FIG. 4, after the door driving device 6 starts the door opening operation (step S <b> 1) on the basis of a command from the door control unit 5, the door opening operation is in progress. The door controller 5 constantly monitors the operation of the microswitch 12 (steps S2 to S4). If a foreign object 16 such as a finger is drawn into the gap G during the door opening operation, the swing panel 8 is pressed by the foreign object 16 to resist the urging force of the tension spring 14 as shown in FIG. The micro switch 12 is turned ON by swinging in the door opening direction so as to expand, and the rubber roller 9 is moved to the guide surface 11a of the guide member 11 in conjunction with the swing of the swing panel 8 in the door opening direction. The rubber roller 9 is sandwiched like a wedge between the guide surface 11a of the guide member and the front side wall surface 4a of the slide door 4, and the slide door 4 stops. That is, the rubber roller 9 is pressed against a portion of the front side wall surface 4 a of the slide door 4 that is close to the door driving device 5, thereby directly braking the slide door 4.

また、マイクロスイッチ１２がＯＮ作動したことにより、その検出信号がドア制御部５に取り込まれてドア制御部５が直ちにドア駆動装置６の戸開動作を停止させる（ステップＳ５）。ここで、戸開動作を停止した後もスライドドア４は慣性にてさらに戸開方向へ変位しようとするが、上述のようにゴムローラ９がスライドドア４を停止させているため、異物１６のさらなる引き込みが防止される。   Further, when the micro switch 12 is turned ON, the detection signal is taken into the door control unit 5 and the door control unit 5 immediately stops the door opening operation of the door driving device 6 (step S5). Here, even after the door opening operation is stopped, the slide door 4 tries to be further displaced in the door opening direction due to inertia. However, since the rubber roller 9 stops the slide door 4 as described above, the foreign matter 16 is further removed. Pull-in is prevented.

次いで、ドア駆動装置６に戸閉動作を開始させることで（ステップＳ６）、異物１６が隙間Ｇから離脱するとともに、ゴムローラ９がスライドドア４とガイド部材１１との間から押し出されてスライドドア４が戸開方向に変位することが可能となり、かご側出入口１を全閉した後に戸閉動作を停止して（ステップＳ７〜Ｓ９）再度戸開動作を開始する（ステップＳ１）。   Next, when the door driving device 6 starts a door closing operation (step S6), the foreign matter 16 is separated from the gap G, and the rubber roller 9 is pushed out between the slide door 4 and the guide member 11 to slide the slide door 4. Can be displaced in the door opening direction, and after the car side doorway 1 is fully closed, the door closing operation is stopped (steps S7 to S9), and the door opening operation is started again (step S1).

以上のように構成したエレベータのドア安全装置によれば、異物１６が隙間Ｇに引き込まれたときに揺動パネル８が隙間Ｇを拡開させるように揺動することで手指等の異物１６への負荷が軽減される上に、揺動パネル８の揺動に連動してゴムローラ９がスライドドア４に直接的に制動をかけるため、異物１６が隙間Ｇに引き込まれてからスライドドア４を停止させるまでの時間的遅れが少なく、引き込まれによる異物１６への負荷がより軽減される。また、ゴムローラ９によりスライドドア４に制動をかける機構は単純な機械要素にて構成されているため、故障が発生しにくい上に、何らかの原因により万が一ドア駆動装置６の戸開動作を停止することができなかった場合にもゴムローラ９がスライドドア４を停止させているため動作の信頼性が高い。   According to the elevator door safety device configured as described above, when the foreign object 16 is drawn into the gap G, the swing panel 8 swings so as to widen the gap G, thereby moving the foreign object 16 such as a finger. In addition, the rubber roller 9 directly brakes the slide door 4 in conjunction with the swing of the swing panel 8, so that the slide door 4 is stopped after the foreign matter 16 is drawn into the gap G. There is little time delay until it is made, and the load on the foreign material 16 due to the drawing is further reduced. Further, since the mechanism for braking the slide door 4 by the rubber roller 9 is composed of a simple mechanical element, it is difficult for the failure to occur, and the door opening operation of the door drive device 6 should be stopped for any reason. Even when the operation cannot be performed, the rubber roller 9 stops the slide door 4, so that the operation reliability is high.

さらに、異物１６が隙間Ｇに引き込まれたときにドア駆動装置６が戸閉動作することで、異物１６が隙間Ｇから離脱するとともに、ゴムローラ９がスライドドア４とガイド部材１１との間から押し出されるため、戸開動作中にスライドドア４を停止させた後にエレベータが円滑に通常動作に復帰することができ、エレベータの運行効率が向上するメリットがある。   Further, when the foreign matter 16 is drawn into the gap G, the door driving device 6 performs a door closing operation, whereby the foreign matter 16 is separated from the gap G and the rubber roller 9 is pushed out between the slide door 4 and the guide member 11. Therefore, after the sliding door 4 is stopped during the door opening operation, the elevator can smoothly return to the normal operation, and there is an advantage that the operation efficiency of the elevator is improved.

その上、揺動パネル８が縦枠２の一部として構成されているため周囲の意匠との調和を損なわない上に、ゴムローラ９とスライドドア４との接触面積が小さいためスライドドア４にゴムローラ９が押し付けられた痕跡が目立たず、乗客に外観上の違和感を与えない。   In addition, since the swing panel 8 is configured as a part of the vertical frame 2, the harmony with the surrounding design is not impaired, and the contact area between the rubber roller 9 and the slide door 4 is small, so that the rubber roller is attached to the slide door 4. The trace of 9 being pressed is inconspicuous and does not give the passengers an uncomfortable appearance.

なお、この実施の形態ではマイクロスイッチ１２を設けて異物１６が引き込まれたときにドア駆動装置６の戸開動作を直ちに停止させるものとしたが、ゴムローラ９にて直接的にスライドドア４の戸開方向への移動を停止させるため、マイクロスイッチ１２は必ずしも必要ではない。マイクロスイッチ１２を設けない場合には、例えば戸開動作を開始してから予め定められた所定の時間を経過してもかご側出入口１が全開していないことをもってゴムローラ９がスライドドア４を停止させたものと判断してドア駆動装置６の戸開動作を停止させ、ドア駆動装置６にて戸閉動作させるようにするとよい。この場合には、異物１６が隙間Ｇに引き込まれたときにその検出信号をドア制御部５に出力するための電気配線が不要となり、ドア安全装置の設置が格段に容易となる上に、コスト的に有利となるメリットがある。   In this embodiment, the microswitch 12 is provided and the door opening operation of the door driving device 6 is immediately stopped when the foreign object 16 is drawn. However, the rubber roller 9 directly opens the door of the slide door 4. The microswitch 12 is not always necessary to stop the movement in the opening direction. When the micro switch 12 is not provided, for example, the rubber roller 9 stops the sliding door 4 when the car side doorway 1 is not fully opened even after a predetermined time has elapsed since the door opening operation was started. It may be determined that the door driving device 6 has been opened and the door opening operation of the door driving device 6 is stopped, and the door driving device 6 performs the door closing operation. In this case, when the foreign object 16 is drawn into the gap G, electrical wiring for outputting a detection signal to the door control unit 5 is not required, and the installation of the door safety device is greatly facilitated. There is an advantage that becomes advantageous.

また、本実施の形態ではいわゆる二枚両開きタイプのかご側出入口１を例にして説明したが、本発明はいわゆる横引き戸形式であれば戸開閉形式を問わずに適用でき、乗場側の出入口に適用することも可能である。さらに、高速スライドドアと、出入口開閉時に高速スライドドアの変位に連動して高速スライドドアよりも低速で且つ高速スライドドアと同方向に変位する低速スライドドアと、を備えた例えば二枚片開きタイプの戸開閉形式の出入口においては、壁体たる低速スライドドアに本発明を適用することも可能であり、高速スライドドアと低速スライドドアの間の隙間に異物が引き込まれたときにゴムローラ９にて両スライドドアを停止させることができる。   Further, in the present embodiment, the so-called double door type car side doorway 1 has been described as an example. However, the present invention can be applied to any door opening / closing type as long as it is a so-called horizontal sliding door type. It is also possible to apply. Furthermore, for example, a two-piece one-sided opening type provided with a high-speed sliding door and a low-speed sliding door that is displaced in the same direction as the high-speed sliding door at a lower speed than the high-speed sliding door in conjunction with the displacement of the high-speed sliding door when opening and closing the entrance In the door opening / closing type of the door, the present invention can also be applied to a low-speed sliding door that is a wall, and when a foreign object is drawn into a gap between the high-speed sliding door and the low-speed sliding door, the rubber roller 9 Both sliding doors can be stopped.
