エレベータのドア装置、エレベータドアのリンクElevator door device, elevator door link

 この発明は、ドアパネルに異物を検出するセーフティシューを備えているエレベータのドア装置、およびドアパネルとセーフティシューとを接続するエレベータドアのリンクに関するものである。 The present invention relates to an elevator door device provided with a safety shoe for detecting foreign matter in a door panel, and to a link of the elevator door connecting the door panel and the safety shoe.

 従来から、エレベータのドア装置では、ドアパネルの戸当たり側の端部にセーフティシューと呼ばれる装置が取り付けられている。このセーフティシューは、通常時はドアパネルの戸当たり側の端部から突出しているが、エレベータのドアパネルが閉まる時に人、物などの異物が挟まれると押し込まれ、ドアパネルに異物が挟まったことを機械的に検出する。そして、異物を検出した場合には、制御装置によってエレベータのドアパネルが開くようなっている。 2. Description of the Related Art Conventionally, in an elevator door device, a device called a safety shoe is attached to the end of the door contact side of a door panel. This safety shoe normally protrudes from the door contact end of the door panel, but it is pushed in when foreign objects such as people and objects are caught when the elevator door panel is closed, so that foreign objects are caught in the door panel. Detect. When a foreign object is detected, the control device opens the door panel of the elevator.

 従来、セーフティシューを突出した状態に戻すために、セーフティシューの自重によって移動前の位置に戻すようにするエレベータのドア装置が提案されている(例えば、特許文献1参照)。 Conventionally, in order to return a safety shoe to a projecting state, an elevator door device has been proposed in which the safety shoe is returned to a position before movement by its own weight (see, for example, Patent Document 1).

特開2014-118293号公報JP, 2014-118293, A

 しかし、特許文献1に示されている従来のエレベータのドア装置では、セーフティシューの自重によって、セーフティシューを移動前の位置に戻すようにしているものの、ペットのリード、紐などの異物が緩んだ状態で挟まった場合に、セーフティシューが押し込まれず、それらを機械的に検出できないことがあった。 However, in the conventional elevator door device shown in Patent Document 1, although the safety shoe is returned to the position before movement by the weight of the safety shoe, foreign matter such as a pet's lead or a string is loosened. When pinched in the state, the safety shoes were not pushed in and sometimes they could not be detected mechanically.

 このように、機械的に挟まった紐が検出できない場合に、かごが移動してしまうと、事故に繋がる場合があり、挟まった紐を検出することが課題となっていた。 As described above, when the mechanically caught string can not be detected, if the car moves, it may lead to an accident, and it has been a problem to detect the caught string.

 この発明は、上記のような課題を解決するためになされたものであり、エレベータのドアに緩んだ紐などの異物が挟まった場合でも、セーフティシューによってそれらの異物をより確実に検出することができるエレベータのドア装置を得ることを目的とする。 The present invention has been made to solve the problems as described above, and it is possible to more reliably detect foreign matter such as a loose string or the like by a safety shoe even if a loose string or the like is caught in an elevator door. The object is to obtain an elevator door device that can be

 この発明によるエレベータのドア装置は、ドアパネル、ドアパネルの戸当たり側の端部から突出しているセーフティシュー、及びドアパネルとセーフティシューとを接続し、セーフティシューをドアパネルの開閉方向に進退させ、セーフティシューがドアパネルの開閉方向に進退するときに回転軸を中心として回転するリンクを備えているエレベータのドア装置において、リンクは、セーフティシューが押し込まれたときに、リンクに作用する力のモーメントをセーフティシューが押し込まれる方向に増加させ、ドアパネルが閉じる方向に加速した時に、リンクに作用する力のモーメントをセーフティシューが突出する方向に増加させるカウンターウェイトを備えている。 The door apparatus of the elevator according to the present invention connects the door panel, the safety shoe projecting from the door contact end of the door panel, and the door panel and the safety shoe, and advances and retracts the safety shoe in the opening and closing direction of the door panel. In an elevator door system provided with a link that rotates about a rotation axis when advancing and retracting in the opening and closing direction of the door panel, the link has a moment of force acting on the link when the safety shoe is depressed. The counterweight is provided to increase in the pushing direction and to increase the moment of force acting on the link in the protruding direction of the safety shoe when the door panel accelerates in the closing direction.

 また、この発明によるエレベータドアのリンクは、ドアパネルとドアパネルの戸当たり側の端部から突出しているセーフティシューとを接続し、セーフティシューをドアパネルの開閉方向に進退させ、セーフティシューがドアパネルの開閉方向に進退するときに回転軸を中心として回転するエレベータドアのリンクにおいて、セーフティシューが押し込まれたときに、リンクに作用する力のモーメントをセーフティシューが押し込まれる方向に増加させ、ドアパネルが閉じる方向に加速した時に、リンクに作用する力のモーメントをセーフティシューが突出する方向に増加させるカウンターウェイトを備えている。 Further, the link of the elevator door according to the present invention connects the door panel and the safety shoe projecting from the door contact end of the door panel, and advances and retracts the safety shoe in the opening and closing direction of the door panel. When the safety shoe is pushed down, the moment of the force acting on the link is increased in the direction in which the safety shoe is pushed in the direction of the door panel closing in the direction of the door panel closing. The counterweight is provided to increase the moment of force acting on the link in the direction in which the safety shoe protrudes when accelerating.

 この発明によるエレベータのドア装置及びエレベータドアのリンクによれば、リンクが、セーフティシューが押し込まれたときに、リンクに作用する力のモーメントをセーフティシューが押し込まれる方向に増加させるカウンターウェイトを備えているため、小さい力でセーフティシューが押し込まれ、緩んだ紐などの異物がエレベータのドアに挟まった場合でも、異物を検出することができる。 According to the elevator door apparatus and elevator door link according to the present invention, the link has a counterweight that increases the moment of force acting on the link in the direction in which the safety shoe is pushed when the safety shoe is pushed. Therefore, even if foreign matter such as a loose string is caught in the door of the elevator, the foreign matter can be detected even if the safety shoe is pushed in with a small force.

 以下、この発明の実施の形態について図面を参照して説明する。
 実施の形態1.
 図1は、この発明の実施の形態1によるエレベータのドア装置の基本構成を示す正面図である。本実施の形態1によるエレベータのドア装置は、ドアパネル1、セーフティシュー2、リンク3、リンク4を備えている。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Embodiment 1
FIG. 1 is a front view showing a basic configuration of an elevator door apparatus according to Embodiment 1 of the present invention. The elevator door apparatus according to the first embodiment includes a door panel 1, a safety shoe 2, a link 3, and a link 4.

 ドアパネル1は、エレベータのかごに取り付けられている。また、ドアパネル1は、かごに設けられた出入口の幅方向にスライドすることにより、かごに設けられた出入口を開閉する。ドアパネル1の戸当たり側の端部には、高さ方向に長いセーフティシュー2が、リンク3、リンク4を介して取り付けられている。 The door panel 1 is attached to the elevator car. Moreover, the door panel 1 opens and closes the entrance provided in the cage by sliding in the width direction of the entrance provided in the car. A safety shoe 2 which is long in the height direction is attached to the end of the door panel 1 on the door contact side via a link 3 and a link 4.

 セーフティシュー2は、ドアパネル1が開閉中にドアパネル1の戸当たり側の端部から突出しており、ドアパネル1が閉まる時に、人、物などの異物に物理的に接触すると、ドアパネル1の内部に押し込まれる。このとき、リンク3、リンク4は、セーフティシュー2の移動に応じて回転する。これにより、後に説明するスイッチ8でセーフティシュー2が押し込まれたことが検出される。これにより、図示しない制御装置が挟み込んだ異物を検出してドアパネル1を開く。 The safety shoe 2 projects from the end of the door contact side of the door panel 1 during opening and closing of the door panel 1, and is pushed into the inside of the door panel 1 when it physically contacts foreign objects such as people and objects when the door panel 1 is closed. Be At this time, the link 3 and the link 4 rotate in accordance with the movement of the safety shoe 2. Thereby, it is detected that the safety shoe 2 is pushed in by the switch 8 described later. As a result, the control device (not shown) detects the foreign matter pinched and opens the door panel 1.

 図2は、この発明の実施の形態1によるエレベータのドア装置のリンク4を示した拡大図である。なお、図1に示すリンク3は、従来のリンクと同様であるため、説明を省略する。 FIG. 2 is an enlarged view showing a link 4 of an elevator door apparatus according to Embodiment 1 of the present invention. In addition, since the link 3 shown in FIG. 1 is the same as that of the conventional link, description is abbreviate | omitted.

 本実施の形態1によるエレベータのドア装置のリンク4は、ブラケット6を介してドアパネル1に取り付けられている。また、リンク4は、ブラケット6に取り付けられた回転軸41を中心として回転可能になっている。また、リンク4の一端はセーフティシュー2に接続されている。 The link 4 of the door apparatus of the elevator according to the first embodiment is attached to the door panel 1 via the bracket 6. Further, the link 4 is rotatable around a rotation shaft 41 attached to the bracket 6. Further, one end of the link 4 is connected to the safety shoe 2.

 リンク4は、ドアパネル1とセーフティシュー2とを接続し、セーフティシュー2をドアパネル1の開閉方向に進退させる。また、リンク4は、セーフティシュー2がドアパネル1の開閉方向に進退するときに、回転軸41を中心として回転する。具体的には、リンク4は、異物を挟んだときにセーフティシュー2がドアパネル1の内部に押し込まれる方向へ回転軸41を中心に回転し、ドアパネル1が通常状態で開閉しているときにセーフティシュー2が突出する方向へ回転軸41を中心に回転する。 The link 4 connects the door panel 1 and the safety shoe 2, and advances and retracts the safety shoe 2 in the opening and closing direction of the door panel 1. The link 4 rotates about the rotation shaft 41 when the safety shoe 2 advances and retracts in the opening and closing direction of the door panel 1. Specifically, when the link 4 holds the foreign object, the safety shoe 2 rotates about the rotation shaft 41 in a direction in which the safety shoe 2 is pushed into the inside of the door panel 1, and safety is performed when the door panel 1 is opened and closed in a normal state. It rotates around the rotation shaft 41 in the direction in which the shoe 2 projects.

 ブラケット6には、スイッチ8が取り付けられている。リンク4は、セーフティシュー2がドアパネル1から突出している状態において、スイッチ8と当接している。スイッチ8は、ドアパネル1が異物を挟み込んだかどうかを検出するためのものである。ドアパネル1が異物を挟み込んで、セーフティシュー2が押し込まれると、リンク4が回転してスイッチ8から離れ、スイッチ8が作動する。これにより、スイッチ8の検出信号が制御装置へ送られ、制御装置の制御によりドアパネル1が閉動作から開動作に反転する。なお、スイッチ8は、セーフティシュー2が押し込まれた時にリンク4と当接して作動するタイプのものであってもよい。 A switch 8 is attached to the bracket 6. The link 4 is in contact with the switch 8 in a state where the safety shoe 2 protrudes from the door panel 1. The switch 8 is for detecting whether the door panel 1 has caught a foreign object. When the door panel 1 sandwiches the foreign matter and the safety shoe 2 is pushed in, the link 4 is rotated to be separated from the switch 8 and the switch 8 is operated. Thereby, a detection signal of the switch 8 is sent to the control device, and the control of the control device reverses the door panel 1 from the closing operation to the opening operation. The switch 8 may be of a type that operates in contact with the link 4 when the safety shoe 2 is pressed.

 リンク4は、回転軸41及びセーフティシュー2の間に連結されているリンク本体と、リンク本体に取り付けられているブラケット43と、ブラケット43に取り付けられているカウンターウェイト42とを備えている。カウンターウェイト42は、回転軸41についてセーフティシュー2の反対側にある。また、カウンターウェイト42は、回転軸41の位置よりも低い位置にある。なお、本実施の形態1では、カウンターウェイト42は、セーフティシュー2と同等の重さであるものとする。リンク4の下方に位置するリンク3の構成は、リンク4からカウンターウェイト42、ブラケット43を除いた構成となっている。また、本実施の形態1では、ブラケット43がリンク本体にボルトで着脱可能に取り付けられている。なお、リンク本体、カウンターウェイト42、及びブラケット43は、単一部材としてもよい。 The link 4 includes a link body connected between the rotation shaft 41 and the safety shoe 2, a bracket 43 attached to the link body, and a counter weight 42 attached to the bracket 43. The counterweight 42 is on the opposite side of the safety shoe 2 with respect to the axis of rotation 41. Further, the counterweight 42 is at a position lower than the position of the rotation shaft 41. In the first embodiment, the counter weight 42 is assumed to have the same weight as the safety shoe 2. The configuration of the link 3 located below the link 4 is a configuration in which the counter weight 42 and the bracket 43 are removed from the link 4. Further, in the first embodiment, the bracket 43 is detachably attached to the link body by a bolt. The link body, the counterweight 42, and the bracket 43 may be a single member.

 図3は、セーフティシュー2が押し込まれた時に、リンク4にどのような力及び力のモーメントが掛かるかを示す拡大図である。セーフティシュー2を押し込むには、回転軸41回りの力のモーメント51を図3において反時計回りにする必要がある。このため、カウンターウェイト42が無い場合、セーフティシュー2を押し込む力52は、セーフティシュー2の質量による荷重53が発生する時計回りの力のモーメントよりも大きいモーメントが発生するような大きさでなければならない。 FIG. 3 is an enlarged view showing what kind of force and moment of force are applied to the link 4 when the safety shoe 2 is pushed. In order to push in the safety shoe 2, it is necessary to make the moment 51 of the force around the rotation shaft 41 counterclockwise in FIG. Therefore, if there is no counter weight 42, the force 52 for pushing the safety shoe 2 must be such that a moment larger than the moment of the clockwise force generated by the load 53 due to the mass of the safety shoe 2 is generated. It does not.

 しかし、この発明の実施の形態1によるエレベータのドア装置では、リンク4にカウンターウェイト42が備えられているため、カウンターウェイト42の質量による荷重54が発生する反時計回りの力のモーメントが、セーフティシュー2の質量による荷重53が発生する時計回りの力のモーメントの一部を相殺する。従って、セーフティシュー2を押し込む力52は、極めて小さくてよい。 However, in the door apparatus of the elevator according to the first embodiment of the present invention, since the link 4 is provided with the counterweight 42, the moment of counterclockwise force generated by the load 54 due to the mass of the counterweight 42 It cancels a part of the clockwise force moment generated by the load 53 due to the mass of the shoe 2. Therefore, the force 52 for pushing the safety shoe 2 may be extremely small.

 このとき、カウンターウェイト42は、リンク4に作用する力のモーメントをセーフティシュー2が押し込まれる方向に増加させている。これにより、セーフティシュー2を押し込む力52を小さくすることができる。 At this time, the counterweight 42 increases the moment of force acting on the link 4 in the direction in which the safety shoe 2 is pushed. As a result, the force 52 for pushing the safety shoe 2 can be reduced.

 なお、カウンターウェイト42が無くてもセーフティシュー2の質量を軽くすることで、セーフティシュー2を押し込む力52を小さくすることができるが、エレベータのドアの開閉時にセーフティシュー2が誤作動を起こすことがある。この場合について、図4を用いて説明する。 Even if there is no counter weight 42, the weight 52 of the safety shoe 2 can be reduced by reducing the mass of the safety shoe 2. However, the safety shoe 2 malfunctions when opening or closing the elevator door. There is. This case will be described with reference to FIG.

 図4は、ドアパネル1が出入口を閉じる動作を行うときに、リンク4及びセーフティシュー2にどのような力及び力のモーメントが掛かるかを示す拡大図である。ドアパネル1の全開位置からドアパネル1を閉じ始める場合、ドアパネル1が閉じる方向に加速度が掛かり、セーフティシュー2は、それとは反対向きの慣性力61を受ける。 FIG. 4 is an enlarged view showing what kind of force and moment of force are applied to the link 4 and the safety shoe 2 when the door panel 1 performs an operation of closing the entrance. When starting to close the door panel 1 from the fully open position of the door panel 1, acceleration is applied in the direction in which the door panel 1 is closed, and the safety shoe 2 receives an inertial force 61 in the opposite direction.

 カウンターウェイト42を備えていない場合においてセーフティシュー2を軽くした場合、セーフティシュー2の質量による荷重53が発生する図4における時計回りの力のモーメントが小さくなる。それに対し、セーフティシュー2が受ける慣性力61が大きいと、それにより発生する反時計回りの力のモーメント62が大きくなる。これにより、セーフティシュー2がドアパネル1に押し込まれ、誤作動を起こす可能性がある。 When the safety shoe 2 is lightened in the case where the counter weight 42 is not provided, the moment of clockwise force in FIG. 4 in which the load 53 due to the mass of the safety shoe 2 is generated is reduced. On the other hand, when the inertial force 61 received by the safety shoe 2 is large, the moment 62 of the counterclockwise force generated thereby becomes large. As a result, the safety shoe 2 may be pushed into the door panel 1 to cause a malfunction.

 しかし、この発明のエレベータのドア装置では、リンク4がカウンターウェイト42を備えているため、カウンターウェイト42に慣性力63が掛かり、図4において時計回りの力のモーメントが発生する。このモーメントが、セーフティシュー2が受ける慣性力61が発生する反時計回りの力のモーメントの一部を相殺する。 However, in the elevator door device of the present invention, since the link 4 is provided with the counterweight 42, an inertial force 63 is applied to the counterweight 42, and a moment of clockwise force is generated in FIG. This moment cancels a part of the counterclockwise force moment generated by the inertial force 61 received by the safety shoe 2.

 このとき、カウンターウェイト42は、リンク4に作用する力のモーメントをセーフティシュー2が突出する方向に増加させている。これにより、セーフティシュー2が押し込まれて、誤動作を起こすことを防止することができる。 At this time, the counterweight 42 increases the moment of the force acting on the link 4 in the direction in which the safety shoe 2 protrudes. This can prevent the safety shoe 2 from being pushed in and causing a malfunction.

 本実施の形態1によるエレベータのドア装置によれば、リンク4が、セーフティシュー2が押し込まれたときに、リンク4に作用する力のモーメントをセーフティシュー2が押し込まれる方向に増加させるカウンターウェイト42を備えているため、小さい力でセーフティシュー2が押し込まれ、緩んだ紐などの異物がエレベータのドアに挟まった場合でも、異物を検出することができる。 According to the door device of the elevator according to the first embodiment, the counter weight 42 causes the link 4 to increase the moment of force acting on the link 4 in the direction in which the safety shoe 2 is pushed when the safety shoe 2 is pushed. Therefore, even if foreign matter such as a loose string is caught in the door of the elevator, foreign matter can be detected even if the safety shoe 2 is pushed in with a small force.

 また、カウンターウェイト42は、ドアパネル1が閉じる方向に加速した時に、リンク4に作用する力のモーメントをセーフティシュー2が突出する方向に増加させるため、エレベータのドアが閉じる時に慣性力によってセーフティシュー2が押し込まれることにより生じる誤動作を防止することができる。 In addition, the counterweight 42 increases the moment of force acting on the link 4 in the direction in which the safety shoe 2 protrudes when the door panel 1 is accelerated in the closing direction, so that the safety shoe 2 is It is possible to prevent a malfunction caused by pressing the

 また、既設のエレベータのドア装置のリンクにカウンターウェイト42を追加するだけで、本実施の形態1によるリンク4を得ることができ、上記の効果を容易に得ることができる。 Further, the link 4 according to the first embodiment can be obtained only by adding the counterweight 42 to the link of the existing elevator door device, and the above effect can be easily obtained.

 以上、この発明によるエレベータのドア装置について説明したが、発明の思想の範囲内において様々な変更が可能である。例えば、図1において、カウンターウェイト42を備えたリンク4を下側に取り付けて、従来のリンクを上側に取り付けるようにしてもよい。また、図1において、カウンターウェイト42を備えたリンク4を上下の両方に用いるようにしてもよい。さらに、図2のスイッチ8の位置は任意に変更することができる。また、ドアパネル1は、エレベータの乗りかご側とエレベータの乗場側の両方にあるが、図1に示すドアパネル1は、どちら側にも適用できる。また、エレベータドアには両開きタイプと片開きタイプがあるが、図1に示すドアパネルは、どちらのタイプにも適用できる。 Although the elevator door device according to the present invention has been described above, various modifications are possible within the scope of the inventive concept. For example, in FIG. 1, the link 4 provided with the counterweight 42 may be attached to the lower side, and the conventional link may be attached to the upper side. Further, in FIG. 1, the link 4 provided with the counterweight 42 may be used for both upper and lower sides. Furthermore, the position of the switch 8 of FIG. 2 can be arbitrarily changed. Also, although the door panel 1 is on both the elevator car side and the elevator landing side, the door panel 1 shown in FIG. 1 can be applied to either side. Although there are double-opening type and single-opening type elevator doors, the door panel shown in FIG. 1 can be applied to either type.
