Description

本発明はエレベータ用ドア装置に係り、特に、ロープ等の可撓性長尺物や針金やパイプ等の棒状長尺物を含む長尺異物がドアに挟み込まれたことを検出できるエレベータ用ドア装置に関する。   The present invention relates to an elevator door device, and in particular, an elevator door device capable of detecting that a long foreign object including a flexible long object such as a rope or a rod-like long object such as a wire or a pipe is caught in the door. About.

従来において、長尺異物がドアに挟み込まれたことを検出できるエレベータ用ドア装置は、例えば特許文献１に示すように、既に提案されている。   Conventionally, as shown in Patent Document 1, for example, an elevator door device that can detect that a long foreign object has been caught in a door has already been proposed.

特許文献１に示す構成は、ドアの全高に亘って異物検出装置を設けているが、ドアの下端と敷居との隙間に長尺異物が巻き込まれた場合、それを検出することができない問題がある。   The configuration shown in Patent Document 1 is provided with a foreign object detection device over the entire height of the door. However, when a long foreign object is caught in the gap between the lower end of the door and the sill, it cannot be detected. is there.

即ち、ドアの下端と敷居との隙間は、エレベータ協会標準（ＪＥＡＳ−２０７ 標０２−５）で６ｍｍ以下となるように規定されているが、ドア装置の製造や据付精度あるいは長期使用による出入口周辺構造の歪み等を考慮すると、その隙間を０ｍｍにすることは不可能であり、通常初期隙間が５ｍｍ程度となるように製造されている。   In other words, the clearance between the lower end of the door and the sill is specified to be 6 mm or less by the Elevator Association Standard (JEAS-207 Standard 02-5). In consideration of structural distortion and the like, it is impossible to make the gap 0 mm, and it is usually manufactured so that the initial gap is about 5 mm.

そのために、ドア下端の５ｍｍの隙間に長尺異物が入り込んだ場合、ドアに設けた異物検出装置ではそれを検出できない問題がある。   For this reason, when a long foreign object enters a 5 mm gap at the lower end of the door, there is a problem that the foreign object detector provided on the door cannot detect it.

他方、特許文献２に示すように、ドアの戸当り側端部に面一となるように、ドア下端と敷居との隙間を塞ぐ遮蔽板を設け、仮に、ドア下端と敷居との隙間に対応する遮蔽板に異物が挟まった場合、ドアが完全に閉じられないので、異物検出装置の機能を有するドア閉じ確認スイッチが入らないので、乗かごの昇降を防止するものが提案されている。   On the other hand, as shown in Patent Document 2, a shielding plate that closes the gap between the lower end of the door and the sill is provided so as to be flush with the door end of the door, and temporarily corresponds to the gap between the lower end of the door and the sill. When foreign matter is caught between the shielding plates, the door cannot be completely closed, and the door closing confirmation switch having the function of the foreign matter detection device is not turned on.

特開２００４−２６２６３６号公報JP 2004-262636 A 特開平９−１２２５４号公報JP-A-9-12254

上記特許文献２に示す異物検出装置は、敷居上面で長尺異物を挟み込んだままドアが閉じた場合、僅かな遊びの範囲でドアが傾斜して異物検出装置の機能を有するドア閉じ確認スイッチが入ってしまう問題がある。このようなドア閉じ時のドアの僅かな傾斜は、物を挟み込んだ場合のほか、製造及び据付段階で稀に発生し、さらには長期使用による出入口周辺構造の歪み等に基づいて生じることがある。   In the foreign object detection device shown in Patent Document 2, when the door is closed with a long foreign object sandwiched between the upper surfaces of the sill, the door closing confirmation switch having the function of the foreign object detection device is inclined by a slight play range. There is a problem that enters. Such a slight inclination of the door when the door is closed occurs rarely in the manufacturing and installation stages, as well as when objects are caught, and may also occur based on distortion of the peripheral structure of the entrance / exit due to long-term use. .

本発明の目的は、敷居上に長尺異物が存在しても、十分にその長尺異物を検出することができるエレベータ用ドア装置を提供することにある。   The objective of this invention is providing the door apparatus for elevators which can fully detect the long foreign material even if a long foreign material exists on a sill.

本発明は上記目的を達成するために、上部がドアレールに案内され下部が前記ドアレールと平行な敷居に案内されて横方向に開閉するドアの戸当り側端部の高さ方向に沿って接触圧力を検出する圧力検出手段を設けると共に、前記ドアの下端の戸当り側端部に位置し前記ドアの閉動作時に前記敷居上の長尺異物を前記圧力検出手段へ誘導する異物誘導手段を設けたのである。   In order to achieve the above-mentioned object, the present invention provides a contact pressure along the height direction of the door end portion of the door that opens and closes laterally with the upper portion guided by the door rail and the lower portion guided by a sill parallel to the door rail. And a foreign substance guiding means for guiding a long foreign object on the sill to the pressure detecting means when the door is closed at a door-closing side end of the door. It is.

以上説明したように本発明によれば、ドアの閉動作時に、敷居上にある長尺異物を異物誘導手段により圧力検出手段に誘導し、この圧力検出手段に誘導した長尺異物を挟み込ませることで、その圧力を検出し、その後の必要な動作を行わせるようにしたので、ドア下部隙間に巻き込まれた長尺異物の検出を不能にしたり、僅かなドアの傾きによって長尺異物の検出を不能にしたりすることを防止することができる。   As described above, according to the present invention, when the door is closed, a long foreign object on the sill is guided to the pressure detecting means by the foreign substance guiding means, and the long foreign matter guided to the pressure detecting means is sandwiched between the long foreign substances. Because the pressure is detected and the necessary operation is performed after that, it is impossible to detect the long foreign object caught in the gap at the lower part of the door, or the long foreign object is detected by a slight inclination of the door. It can be prevented from becoming impossible.

以下本発明によるエレベータ用ドア装置の第１の実施の形態を図１〜図５に示す両開きのエレベータ用ドア装置に基づいて説明する。   A first embodiment of an elevator door device according to the present invention will be described below on the basis of a double door elevator device shown in FIGS.

両開きのエレベータ用ドア装置は、門型の出入口枠体１と、その下方に水平に配設された敷居２と、前記出入口枠１の上方に前記敷居２と平行に配設されたドアレール３と、このドアレール３に懸垂されて左右方向に案内されたドア４Ａ，４Ｂとから構成されている。   The double door door device for elevator includes a gate-shaped entrance / exit frame 1, a sill 2 horizontally disposed below the door frame 3, and a door rail 3 disposed above the entrance / exit frame 1 in parallel with the sill 2. The doors 4A and 4B are suspended from the door rail 3 and guided in the left-right direction.

前記ドア４Ａ，４Ｂは、その上端部を前記ドアレール３上を転動するローラ５を軸支したハンガー６によって夫々懸垂されており、下端部には前記敷居２の溝７内に臨むガイド手段８を備えている。このガイド手段８は、前記ドア４Ａ，４Ｂに固定された支持金具９と、この支持金具によって支持され前記溝７内を摺動するガイドシュー１０とを有している。   The doors 4 </ b> A and 4 </ b> B are respectively suspended at their upper ends by hangers 6 that pivotally support rollers 5 that roll on the door rail 3, and guide means 8 that faces the groove 7 of the sill 2 at the lower ends. It has. The guide means 8 includes a support fitting 9 fixed to the doors 4A and 4B, and a guide shoe 10 supported by the support fitting and sliding in the groove 7.

上記構成とすることで、図示しない駆動手段の動力によって、前記ドア４Ａ，４Ｂは左右に駆動され、出入口枠１を開閉する。   With the above configuration, the doors 4A and 4B are driven left and right by the power of a driving means (not shown) to open and close the entrance / exit frame 1.

一方、前記ドア４Ａ，４Ｂの戸当り側端部には、その全高に亘って圧力検出手段１１Ａ，１１Ｂが設けられている。この圧力検出手段１１Ａ，１１Ｂは、例えばドア開閉方向に隙間を介しドアの全高に亘って対向配置された可撓性の箔状電極とこれらを通常時には間隔をもって対向保持させる周知の絶縁弾性体（いずれも図示せず）から構成されており、箔状電極からは図示しない信号線が引き出され、図示しないエレベータ制御装置に接続されている。   On the other hand, pressure detection means 11A and 11B are provided over the entire height of the door end portions of the doors 4A and 4B. The pressure detection means 11A and 11B are, for example, a well-known insulating elastic body (for example, a flexible foil-like electrode that is opposed to the entire height of the door through a gap in the door opening / closing direction and that holds the electrode at regular intervals. Neither is shown), and a signal line (not shown) is drawn from the foil-like electrode and connected to an elevator control device (not shown).

さらに、各ドア４Ａ，４Ｂの下端部の戸当り側端部には、異物誘導手段１２Ａ，１２Ｂが設けられている。これら異物誘導手段１２Ａ，１２Ｂは、ガイド手段８の支持金具９に固定された塞ぎ板である。この塞ぎ板は、各ドア４Ａ，４Ｂの下端の戸当り側端部に位置して前記ドア４Ａ，４Ｂと前記敷居２との隙間を塞ぐものである。また、図２に示すように、この塞ぎ板のドア閉じ方向側下端は、前記敷居２の溝７内に位置すると共に、前記圧力検出手段１１Ａ，１１Ｂの先端よりもドア閉じ方向に突出している。そして、この塞ぎ板は、前記敷居２の溝７内のドア閉じ方向側下端から前記圧力検出手段１１Ａ，１１Ｂの先端に至る上向きの傾斜部１３Ａ，１３Ｂを有している。このほか、図３に示すように、異物誘導手段１２Ａ，１２Ｂである塞ぎ板は、平面的に見て敷居２の溝７の幅方向に、互いに変位して設けられており、ドア４Ａ，４Ｂが全閉したとき干渉しないようにしている。   Further, foreign matter guiding means 12A and 12B are provided at the door end side end portions of the lower ends of the doors 4A and 4B. These foreign material guiding means 12A and 12B are blocking plates fixed to the support fitting 9 of the guide means 8. This closing plate is located at the door-contact side end of the lower end of each door 4A, 4B and closes the gap between the door 4A, 4B and the sill 2. Further, as shown in FIG. 2, the lower end of the closing plate on the door closing direction side is located in the groove 7 of the sill 2 and protrudes in the door closing direction from the tips of the pressure detecting means 11A and 11B. . The closing plate has upward inclined portions 13A and 13B extending from the lower end in the door closing direction in the groove 7 of the sill 2 to the tips of the pressure detecting means 11A and 11B. In addition, as shown in FIG. 3, the closing plates which are the foreign material guiding means 12A and 12B are provided so as to be displaced from each other in the width direction of the groove 7 of the sill 2 when seen in a plan view. Does not interfere when is fully closed.

上記構成の両開きのエレベータ用ドア装置において、図１に示すように、敷居２上に長尺異物１４、例えば、ペット犬のチェーン等からなるリードが存在していた場合、ドア閉じ動作の過程で、一方あるいは両方のドアの異物誘導手段１２Ａ，１２Ｂが、リードをドア閉じの中央側に次第に移動させて行く。この移動の過程で、ペット犬の飼い主が気付いてリードを手繰り寄せるか手放して敷居２上からリードを撤去すれば各ドア４Ａ，４Ｂは全閉して乗かごは昇降を開始する。しかしながら、飼い主が気付かず、リードがドア閉じの中央側に至った場合、両側の異物誘導手段１２Ａ，１２Ｂが、図５に示すように、出入口進行方向から見て、その傾斜部１３Ａ，１３Ｂが交差することによって、リードは掬い上げられ、圧力検出手段１１Ａ，１１Ｂの間に誘導される。誘導されたリードは、ドア閉じ動作によって圧力検出手段１１Ａ，１１Ｂの少なくとも一方を撓ませ、それによって異物の存在が検出される。圧力検出手段１１Ａ，１１Ｂからの検出信号は制御装置に送られて、乗かごあるいは乗り場側に設けた案内手段（スピーカや表示装置）を介して警報を発すると共に、乗かごを昇降させる信号の出力を停止させる。これにより、リードをドア４Ａ，４Ｂに挟み込んだまま乗かごを昇降させるために発生する各種事故を防止することができる。   In the double door door device having the above-described structure, as shown in FIG. 1, when a lead made of a long foreign material 14, for example, a pet dog chain, exists on the sill 2, The foreign substance guiding means 12A and 12B of one or both doors gradually move the lead toward the center side of the door closing. In the course of this movement, if the owner of the pet dog notices and pulls the lead or releases it to remove the lead from the sill 2, the doors 4A and 4B are fully closed and the car starts to move up and down. However, when the owner does not notice and the lead reaches the center side of the door closing, the foreign matter guiding means 12A and 12B on both sides are inclined as shown in FIG. By crossing, the lead is scooped up and guided between the pressure detection means 11A and 11B. The induced lead bends at least one of the pressure detection means 11A and 11B by a door closing operation, and thereby the presence of a foreign object is detected. Detection signals from the pressure detection means 11A and 11B are sent to the control device, and an alarm is issued via a guide means (speaker or display device) provided on the car or landing side, and a signal for raising and lowering the car is output. Stop. As a result, various accidents that occur when the car is raised and lowered while the lead is sandwiched between the doors 4A and 4B can be prevented.

ところで、上記実施の形態において、異物誘導手段１２Ａ，１２を塞ぎ板としたことで、敷居２とドア４Ａ，４Ｂ間の隙間を塞ぐことができるので、防炎、防火仕様のエレベータ用ドア装置には好適である。しかし、防炎、防火仕様のエレベータ用ドア装置以外では、異物誘導手段１２Ａ，１２を板状に形成させる必要はなく、その場合には傾斜部１３Ａ，１３Ｂが形成できる部材をガイド手段８に支持させればよい。   By the way, in the said embodiment, since the foreign material guidance | guidance | derivation means 12A and 12 are used as the closing board, since the clearance gap between the sill 2 and the doors 4A and 4B can be closed, it becomes a flame-proof and fire-proof specification elevator door apparatus. Is preferred. However, it is not necessary to form the foreign material guiding means 12A and 12 in a plate shape except for the elevator door device of flameproof and fireproof specifications. In this case, the member that can form the inclined portions 13A and 13B is supported by the guide means 8. You can do it.

さらに、前記傾斜部１３Ａ，１３Ｂの角度は任意であるが、ドアの閉じ状態や乗客の乗降を考慮して決定すればよい。また、傾斜部１３Ａ，１３Ｂは必ずしも、直線状に形成する必要はなく、ドア移動方向に沿った凹曲状に形成してもよい。   Furthermore, although the angles of the inclined portions 13A and 13B are arbitrary, they may be determined in consideration of the closed state of the door and passengers getting on and off. In addition, the inclined portions 13A and 13B are not necessarily formed in a linear shape, and may be formed in a concave shape along the door moving direction.

以上に実施の形態では、板状の異物誘導手段１２Ａ，１２Ｂを敷居２の幅方向にずらして設けたものであるが、長尺異物１４の救い上げを容易にするために、図６に示す第１の変形例のように、例えば、ドア４Ａ側の板状の異物誘導手段１２Ａをドア４Ａの圧さ方向の中央部から突出させ、ドア４Ｂ側の板状の異物誘導手段１２Ｂを、中央の異物誘導手段１２Ａを挟み込むように、２つの誘導手段１２Ｂ１，１２Ｂ２を突出させればよい。   As described above, in the embodiment, the plate-like foreign material guiding means 12A and 12B are provided by being shifted in the width direction of the sill 2, but in order to facilitate the rescue of the long foreign material 14, it is shown in FIG. As in the first modification, for example, the plate-like foreign material guiding means 12A on the door 4A side is protruded from the central portion in the pressure direction of the door 4A, and the plate-shaped foreign material guiding means 12B on the door 4B side is The two guiding means 12B1 and 12B2 may be protruded so as to sandwich the foreign matter guiding means 12A.

さらに、以上の実施の形態は、異物誘導手段１２Ａ，１２Ｂをガイド手段８の支持金具９を利用して固定したものであるが、図７に示す第２の変形例のように、支持金具９を戸当り側に突出させ、この突出した支持金具９を異物誘導手段１２Ａ，１２Ｂとすることも可能である。その場合には、全閉時の緩衝を防止するために、各ドア４Ａ，４Ｂの支持金具９の突出させる部分を、敷居２の幅方向で互いに逆方向に変位させた後、突出させるようにすればよい。   Further, in the above embodiment, the foreign material guiding means 12A and 12B are fixed using the support metal fitting 9 of the guide means 8. However, as in the second modification shown in FIG. It is also possible to project the support bracket 9 that protrudes toward the door-end side, and to use the protruding metal fittings 9 as the foreign matter guiding means 12A and 12B. In that case, in order to prevent buffering when fully closed, the protruding portions of the support fittings 9 of the doors 4A and 4B are displaced in opposite directions in the width direction of the sill 2 and then protruded. do it.

ところで、以上の実施の形態は、異物誘導手段１２Ａ，１２Ｂをガイド手段８に固定したものであるが、ドア４Ａ，４Ｂの下部に直接固定してもよいのは勿論である。   In the above embodiment, the foreign material guiding means 12A and 12B are fixed to the guide means 8, but it is needless to say that they may be directly fixed to the lower portions of the doors 4A and 4B.

また、以上の実施の形態は、がごドアに関するものであるが、乗り場ドアに関しても同様なことが云える。   Moreover, although the above embodiment is related to a gag door, the same can be said for a landing door.

以上の実施の形態はまた、ドア４の戸当り側端部の全高に亘って圧力検出手段１１を設けているが、異物誘導手段によって誘導された異物を圧力検出手段１１で検出できればよいので、ドア４の戸当り側端部の一部にのみ圧力検出手段１１を設けるようにしてもよい。   In the above embodiment, the pressure detection means 11 is provided over the entire height of the door-contact side end portion of the door 4, but it is sufficient that the foreign matter induced by the foreign matter guidance means can be detected by the pressure detection means 11. You may make it provide the pressure detection means 11 only in a part of door end side part of the door 4. As shown in FIG.

さらに、以上の実施の形態は、両開きのエレベータ用ドア装置を一例に説明したが、片開きのエレベータ用ドア装置にも適用できることは云うまでもない。その場合には、一方側のドアの戸当り側と、このドアと対向する出入口枠の戸当り部分に、圧力検出手段と異物誘導手段とを上記実施の形態にしたがって設けて対応することで、両開きのエレベータ用ドア装置と同じように長尺異物の検出を行うことができる。   Furthermore, although the above embodiment has been described by taking a double-open elevator door device as an example, it is needless to say that the embodiment can also be applied to a single-open elevator door device. In that case, by providing a pressure detecting means and a foreign substance guiding means according to the above-described embodiment, and corresponding to the door contact side of the door on one side and the door contact portion of the entrance / exit frame facing this door, Long foreign objects can be detected in the same manner as a double door elevator door device.

このほか、異物誘導手段をガイド手段８あるいはドア４Ａ，４Ｂに一体に設けた例を説明したが、ドアの閉動作時に、ドアの移動力を利用したり、専用の駆動装置を駆動させたりして昇降あるいは回転動作して異物を掬い上げ、掬い上げた長尺異物を圧力検出手段まで誘導する異物誘導手段を設けてもよい。   In addition, the example in which the foreign matter guiding means is provided integrally with the guide means 8 or the doors 4A and 4B has been described. However, when the door is closed, the moving force of the door is used or a dedicated driving device is driven. It is also possible to provide a foreign material guiding means for scooping up and rotating or rotating the foreign material to guide the long foreign material thus scooped up to the pressure detecting device.
