Description

本発明は、戸開中のかごが、ブレーキの異常等、何らかの理由により、想定される戸開走行可能範囲を超えて、戸開したまま移動をした場合に、速やかにかごを停止させる開門発車防止機能を備えたエレベータ装置に関するものであり、開門発車防止機能の動作確認を容易に行うことのできるエレベータ装置に関する。   The present invention provides an opening gate that quickly stops a car when the car is opened while the car is open while the car is not open for some reason, such as a brake failure. The present invention relates to an elevator apparatus having a prevention function, and more particularly to an elevator apparatus capable of easily confirming the operation of the opening gate prevention function.

一般に、着床位置を修正する際のリレベル動作を除き、戸開状態で停止中のかごが移動することはない。しかしながら、何らかの理由により、かごが戸開状態にも関わらず想定された戸開走行可能範囲の外へ移動してしまった場合の対策として、開門発車防止機能を備えたエレベータ装置がある（例えば、特許文献１参照）。   In general, a car that is stopped in a door open state does not move except for a releveling operation when the landing position is corrected. However, for some reason, as a countermeasure when the car has moved out of the assumed open door travelable range in spite of the open door state, there is an elevator device equipped with a gate opening prevention function (for example, Patent Document 1).

このような従来技術における開門発車防止機能を備えたエレベータ装置は、ドアが開いていることを検知した場合には、かご位置が戸開状態で移動してよい所定範囲以内であるか否かを判定する。そして、エレベータ装置は、戸開状態のまま、かごが所定範囲外に移動したことを検知した場合には、エレベータを停止させている。   When such an elevator apparatus having a gate opening prevention function in the prior art detects that the door is open, it is determined whether the car position is within a predetermined range within which the car can move in the door open state. judge. Then, when the elevator apparatus detects that the car has moved out of the predetermined range with the door open, the elevator apparatus stops the elevator.

しかしながら、従来技術には、以下のような課題がある。
従来のエレベータ装置において、開門発車防止機能が正常に動作するか否かを検査する際には、実際に開門発車状態を作り出す必要があった。しかしながら、そもそも、エレベータ装置は、開門発車状態にならないように作られている。従って、従来のエレベータ装置は、開門発車防止機能をチェックするために、開門発車状態を実際に発生させる試験モードを別途設けなければならず、通常運転モードの動作回路をマスクして、動作試験をしなければならなかった。However, the prior art has the following problems.
In a conventional elevator apparatus, when inspecting whether or not the gate opening prevention function operates normally, it is necessary to actually create the gate opening state. However, in the first place, the elevator apparatus is made so as not to be in the state of starting the gate. Therefore, in order to check the gate opening prevention function, the conventional elevator apparatus must be provided with a separate test mode for actually generating the gate opening state, and the operation test is performed by masking the operation circuit in the normal operation mode. Had to do.

The position of the car, and at least one of the car door and the landing door is in an open state based on the detection result of the car position detecting means for detecting whether the car is open or not, and the door opening / closing detecting means and the car position detecting means. When the vehicle is outside the door opening travelable range, it is determined that the vehicle is in an open gate departure state, and the elevator device includes an open gate prevention means having an open gate departure prevention function for stopping the car, the open gate departure prevention means having A virtual signal generating means for generating a virtual signal for virtually creating the opening and departure state in the test mode for verifying the opening and departure prevention function; In the test mode, the gate departure prevention means is based on the detection results of the door opening / closing detection means and the car position detection means, and gives priority to the virtual signal generated by the virtual signal generation means, and is in the opening gate departure state. If it is determined, the car is stopped , the virtual signal generating means generates a signal for virtually creating the door open state in the test mode as a virtual signal, and the gate opening prevention means is in the test mode. detection result by the position detection means is a door open travelable range, if the door open state is virtually generated by the virtual signal generator determines that the car from starting under the door state, shall stop the car It is.

In the following description, the term “door open” refers to a state including a case where the door is not closed (that is, a case where the door is not completely open but is not half closed). Means.

実施の形態１．
図１は、本発明の実施の形態１におけるエレベータ装置の構成図である。このエレベータ装置は、かご位置検出手段１、乗場ドア開閉検出手段２、かごドア開閉検出手段３、開門発車防止手段４、かご移動手段５、仮想ドア開閉信号生成手段６、かご１０、かごドア１１、および乗場ドア１２を備えている。ここで、乗場ドア開閉検出手段２およびかごドア開閉検出手段３は、ドア開閉検出手段に相当する。Embodiment 1 FIG.
FIG. 1 is a configuration diagram of an elevator apparatus according to Embodiment 1 of the present invention. The elevator apparatus includes a car position detecting means 1, a landing door opening / closing detecting means 2, a car door opening / closing detecting means 3, a gate opening prevention means 4, a car moving means 5, a virtual door opening / closing signal generating means 6, a car 10, and a car door 11. , And a landing door 12. Here, the landing door opening / closing detection means 2 and the car door opening / closing detection means 3 correspond to door opening / closing detection means.

エレベータのかご１０は、かご移動手段５によって移動・停止が制御されている。また、開門発車防止手段４は、開門発車状態を検出した際に、かご１０を停止させる機能を有している。さらに、仮想ドア開閉信号生成手段６は、開門発車防止機能の検証用として、試験モード時にダミー信号を生成し、開門発車防止手段４に与える機能を有している。   The elevator car 10 is controlled to move and stop by the car moving means 5. Further, the gate opening prevention means 4 has a function of stopping the car 10 when the gate opening state is detected. Further, the virtual door opening / closing signal generating means 6 has a function of generating a dummy signal during the test mode and giving it to the opening gate departure prevention means 4 for verification of the opening gate departure prevention function.

次に、本実施の形態１の技術的特徴である開門発車防止機能の検証動作を中心に、具体的な動作を説明する。
かご位置検出手段１は、かご１０の位置を検出する。また、乗場ドア開閉検出手段は、各階に設けられた乗場ドア１２の開閉状態を検出する。さらに、かごドア開閉検出手段３は、かご１０に設けられたかごドア１１の開閉状態を検出する。Next, a specific operation will be described focusing on the verification operation of the opening gate departure prevention function which is a technical feature of the first embodiment.
The car position detection means 1 detects the position of the car 10. The landing door opening / closing detection means detects the opening / closing state of the landing doors 12 provided on each floor. Furthermore, the car door open / close detection means 3 detects the open / closed state of the car door 11 provided in the car 10.

通常運転モード時において、開門発車防止手段４は、かご位置検出手段１、乗場ドア開閉検出手段２、およびかごドア開閉検出手段３のそれぞれから検出信号を受け取る。そして、開門発車防止手段４は、かご位置検出手段１で検出されたかご１０の位置が、戸開走行可能範囲（戸開状態でかご１０を昇降移動させてよい範囲）から逸脱しており、乗場ドアが閉状態でないか、あるいはかごドア１１が閉状態でない場合（すなわち、戸開状態の場合）には、開門発車と判定し、かご１０を停止させる。   In the normal operation mode, the gate departure prevention means 4 receives detection signals from the car position detection means 1, the landing door opening / closing detection means 2, and the car door opening / closing detection means 3, respectively. The gate start prevention means 4 is such that the position of the car 10 detected by the car position detection means 1 deviates from the door opening travelable range (the range in which the car 10 can be moved up and down in the door open state). When the landing door is not closed or the car door 11 is not closed (that is, when the door is open), it is determined that the gate has started and the car 10 is stopped.

一方、試験モード時において、開門発車防止手段４は、かご位置検出手段１、および仮想ドア開閉信号生成手段６のそれぞれから検出信号を受け取る。すなわち、開門発車防止手段４は、試験モード時においては、乗場ドア開閉検出手段２およびかごドア開閉検出手段３の代わりに、仮想ドア開閉信号生成手段６から仮想ドア開閉信号としてダミー信号を優先して受け取る。   On the other hand, in the test mode, the gate departure prevention means 4 receives detection signals from the car position detection means 1 and the virtual door opening / closing signal generation means 6. That is, the gate opening prevention means 4 gives priority to a dummy signal as a virtual door opening / closing signal from the virtual door opening / closing signal generation means 6 instead of the landing door opening / closing detection means 2 and the car door opening / closing detection means 3 in the test mode. Receive.

そして、開門発車防止手段４は、かご位置検出手段１で検出されたかご１０の位置が、戸開走行可能範囲（戸開状態でかご１０を昇降移動させてよい範囲）から逸脱しており、かつ、仮想ドア開閉信号生成手段６からのダミー信号としてドアが閉状態でない信号を受け取った場合には、開門発車と判定し、かご１０を停止させる。   The gate start prevention means 4 is such that the position of the car 10 detected by the car position detection means 1 deviates from the door opening travelable range (the range in which the car 10 can be moved up and down in the door open state). When a signal indicating that the door is not closed is received as a dummy signal from the virtual door opening / closing signal generating means 6, it is determined that the gate has started and the car 10 is stopped.

図２は、本発明の実施の形態１のエレベータ装置の試験モード時において、開門発車防止機能を検証する際の一連の処理を示したフローチャートである。   FIG. 2 is a flowchart showing a series of processing when verifying the gate opening prevention function in the test mode of the elevator apparatus according to Embodiment 1 of the present invention.

まず、かご１０を、戸開可能位置（すなわち、各階床において戸開としてよい範囲にかご１０が停止している状態）にて、戸閉状態（すなわち、かごドア１１および乗場ドア１２の両方を閉状態）にする（ステップＳ２１）。戸開している場合には、戸を閉める。この際、開門発車防止手段４は、かご位置検出手段１により検出されたかご１０の位置に基づいて、かご１０があらかじめ設定された戸開可能位置の範囲内にいるか否かを判断できる。   First, when the car 10 is in a door-openable position (that is, the car 10 is stopped in a range where each door can be opened), both the car door 11 and the landing door 12 are turned on. (Closed state) (step S21). If the door is open, close the door. At this time, the gate opening prevention means 4 can determine whether or not the car 10 is within the range of the door openable position set in advance based on the position of the car 10 detected by the car position detecting means 1.

次に、仮想ドア開閉信号生成手段６は、開門発車防止機能の試験モード時において、ドアが閉状態でない信号をダミー信号として出力する（ステップＳ２２）。一方、開門発車防止手段４は、開門発車防止機能の試験モード時において、乗場ドア開閉検出手段２およびかごドア開閉検出手段３の代わりに、仮想ドア開閉信号生成手段６からのダミー信号を優先して受け取る（ステップＳ２３）。   Next, the virtual door opening / closing signal generating means 6 outputs a signal indicating that the door is not closed as a dummy signal in the test mode of the opening gate departure prevention function (step S22). On the other hand, the gate opening prevention means 4 gives priority to the dummy signal from the virtual door opening / closing signal generation means 6 instead of the landing door opening / closing detection means 2 and the car door opening / closing detection means 3 in the test mode of the opening gate departure prevention function. (Step S23).

次に、かご移動手段５は、かご１０を移動開始させ（ステップＳ２４）、かご１０を戸開走行可能範囲の外へ移動させる（ステップＳ２５）。この際、開門発車防止手段４は、かご位置検出手段により検出されたかご１０の位置に基づいて、かご１０があらかじめ設定された戸開走行可能範囲内にいるか否かを判断できる（ステップＳ２６）。なお、かご位置検出手段１により、かご位置が戸開走行可能範囲外という信号を生成し、開門発車防止手段４に入力するようにしてもよい。   Next, the car moving means 5 starts to move the car 10 (step S24), and moves the car 10 to the outside of the door opening travelable range (step S25). At this time, the gate opening prevention means 4 can determine whether or not the car 10 is within a preset openable travel range based on the position of the car 10 detected by the car position detecting means (step S26). . The car position detection means 1 may generate a signal indicating that the car position is outside the door openable travel range and input the signal to the gate opening prevention means 4.

この結果、開門発車防止手段４は、仮想ドア開閉信号生成手段６からのダミー信号を受け取ることで、かご１０が戸開走行可能範囲外にも関わらず戸開したまま移動していると仮想的に判定し、かごを停止させることとなる（Ｓ２７）。従って、実際には、戸閉状態としたままで、かご１０を移動させた上で、開門発車防止機能の検証を容易に行うことができる。   As a result, the gate opening prevention means 4 receives the dummy signal from the virtual door opening / closing signal generating means 6, so that the car 10 is virtually moved when it is moved open even though it is outside the door openable range. And the car is stopped (S27). Therefore, in practice, the car opening prevention function can be easily verified after the car 10 is moved with the door closed.

以上のように、実施の形態１によれば、開門発車防止の機能試験において、仮想ドア開閉信号生成手段から仮想的にドアが開状態であることを示すダミー信号を出力することで、実際には戸閉状態のままでかごを移動させ、容易に検証結果を得ることができる。この結果、戸開状態で走行させるといった非定常的な動作を強制的に行わせる必要なく、開門発車防止の機能試験を確実に行うことができる。   As described above, according to the first embodiment, in the functional test for preventing the opening of the gate, the virtual door opening / closing signal generating means actually outputs a dummy signal indicating that the door is open, Can move the car with the door closed and easily obtain the verification results. As a result, it is possible to reliably perform the function test for preventing the start of the gate opening without forcibly performing an unsteady operation such as running in the door open state.

実施の形態２．
先の実施の形態１では、試験モード時のダミー信号として、ドアが開状態である信号を仮想的に生成して、開門発車防止の機能試験を容易に実施する場合について説明した。これに対して、本実施の形態２では、試験モード時のダミー信号として、かご位置が戸開走行可能範囲でない信号を仮想的に生成して、開門発車防止の機能試験を容易に実施する場合について説明する。Embodiment 2. FIG.
In the first embodiment, the case has been described in which a signal indicating that the door is in an open state is virtually generated as a dummy signal in the test mode, and the functional test for preventing the opening of the gate is easily performed. On the other hand, in the second embodiment, as a dummy signal at the time of the test mode, a signal for which the car position is not within the door openable travel range is virtually generated, and the function test for preventing the opening of the gate is easily performed. Will be described.

図３は、本発明の実施の形態２におけるエレベータ装置の構成図である。このエレベータ装置は、かご位置検出手段１、乗場ドア開閉検出手段２、かごドア開閉検出手段３、開門発車防止手段４、かご移動手段５、仮想かご位置信号生成手段７、かご１０、かごドア１１、および乗場ドア１２を備えている。先の実施の形態１における図１の構成と比較すると、本実施の形態２における図３の構成は、仮想ドア開閉信号生成手段６の代わりに仮想かご位置信号生成手段７を備えている点が異なっている。   FIG. 3 is a configuration diagram of an elevator apparatus according to Embodiment 2 of the present invention. The elevator apparatus includes a car position detecting means 1, a landing door opening / closing detecting means 2, a car door opening / closing detecting means 3, a gate opening prevention means 4, a car moving means 5, a virtual car position signal generating means 7, a car 10, and a car door 11. , And a landing door 12. Compared with the configuration in FIG. 1 in the first embodiment, the configuration in FIG. 3 in the second embodiment is provided with a virtual car position signal generation means 7 instead of the virtual door opening / closing signal generation means 6. Is different.

仮想かご位置信号生成手段７は、開門発車防止機能の検証用として、試験モード時にダミー信号を生成し、開門発車防止手段４に与える機能を有している。そこで、本実施の形態２の技術的特徴である開門発車防止機能の検証動作を中心に、具体的な動作を説明する。なお、通常運転モード時の動作は、先の実施の形態１と同じであり、説明を省略する。   The virtual car position signal generation means 7 has a function of generating a dummy signal in the test mode and giving it to the opening gate departure prevention means 4 for verification of the opening gate departure prevention function. Therefore, a specific operation will be described focusing on the verification operation of the opening gate departure prevention function, which is a technical feature of the second embodiment. The operation in the normal operation mode is the same as that in the first embodiment, and a description thereof is omitted.

試験モード時において、開門発車防止手段４は、乗場ドア開閉検出手段２、かごドア開閉検出手段３、および仮想かご位置信号生成手段７のそれぞれから検出信号を受け取る。すなわち、開門発車防止手段４は、試験モード時においては、かご位置検出手段１の代わりに、仮想かご位置信号生成手段７から仮想かご位置としてダミー信号を優先して受け取る。   In the test mode, the gate departure prevention means 4 receives detection signals from the landing door opening / closing detection means 2, the car door opening / closing detection means 3, and the virtual car position signal generation means 7. In other words, the gate departure prevention means 4 receives the dummy signal preferentially as a virtual car position from the virtual car position signal generation means 7 instead of the car position detection means 1 in the test mode.

そして、開門発車防止手段４は、仮想かご位置信号生成手段７からのダミー信号が、戸開走行可能範囲（戸開状態でかご１０を昇降移動させてよい範囲）から逸脱しており、かつ、乗場ドアが開状態であるか、あるいはかごドアが開状態である場合には、開門発車と判定し、かご１０を停止させる。   The gate departure prevention means 4 is such that the dummy signal from the virtual car position signal generation means 7 deviates from the door opening travelable range (the range in which the car 10 can be moved up and down in the door open state), and If the landing door is in the open state or the car door is in the open state, it is determined that the gate has started and the car 10 is stopped.

図４は、本発明の実施の形態２のエレベータ装置の試験モード時において、開門発車防止機能を検証する際の一連の処理を示したフローチャートである。   FIG. 4 is a flowchart showing a series of processes when verifying the gate opening prevention function in the test mode of the elevator apparatus according to Embodiment 2 of the present invention.

まず、かご１０を、戸開可能位置（すなわち、各階床において戸開としてよい範囲にかご１０が停止している状態）にて、戸開状態（すなわち、かごドア１１および乗場ドア１２の両方を閉状態）にする（ステップＳ４１）。戸閉している場合には、戸を開ける。   First, when the car 10 is in a door openable position (that is, the car 10 is stopped in a range where each door can be opened), both the car door 11 and the landing door 12 are opened. (Closed state) (step S41). If the door is closed, open the door.

次に、仮想かご位置信号生成手段７は、開門発車防止機能の試験モード時において、戸開走行可能範囲内の位置信号をダミー信号として出力する（ステップＳ４２）。一方、開門発車防止手段４は、開門発車防止機能の試験モード時において、かご位置検出手段１の代わりに、仮想かご位置信号生成手段７からのダミー信号を優先して受け取る（ステップＳ４３）。次に、かご移動手段５は、戸開状態で、かご１０を移動開始させる（ステップＳ４４）。   Next, the virtual car position signal generation means 7 outputs a position signal within the door openable range as a dummy signal in the test mode of the gate opening prevention function (step S42). On the other hand, the gate opening prevention means 4 preferentially receives a dummy signal from the virtual car position signal generation means 7 instead of the car position detection means 1 in the test mode of the opening gate departure prevention function (step S43). Next, the car moving means 5 starts moving the car 10 in the door open state (step S44).

次に、仮想かご位置信号生成手段７は、開門発車防止機能の試験モード時において、かご１０の移動開始後に、実際にはかご１０が戸開走行可能範囲内である状態で、戸開走行可能範囲外の位置信号をダミー信号として出力する（ステップＳ４５）。一方、開門発車防止手段４は、かご位置検出手段１の代わりに、仮想かご位置信号生成手段７から戸開走行可能範囲外の位置信号をダミー信号として受け取る（ステップＳ４６）。   Next, the virtual car position signal generation means 7 can open the door 10 while the car 10 is actually within the door openable range after the start of the movement of the car 10 in the test mode of the opening gate departure prevention function. A position signal outside the range is output as a dummy signal (step S45). On the other hand, the gate opening prevention means 4 receives, as a dummy signal, a position signal outside the door openable travel range from the virtual car position signal generation means 7 instead of the car position detection means 1 (step S46).

この結果、開門発車防止手段４は、仮想かご位置信号生成手段７からのダミー信号を受け取ることで、かご１０が実際には戸開走行可能範囲内であるにも関わらず、戸開走行可能範囲外で戸開したまま移動していると仮想的に判定し、かご１０を停止させることとなる（Ｓ４７）。従って、実際には、戸開走行可能範囲内にかご１０が位置している状態で、開門発車防止機能の検証を容易に行うことができる。   As a result, the gate opening prevention means 4 receives the dummy signal from the virtual car position signal generation means 7, so that the car 10 is actually within the door openable range, but the door openable driveable range. The car 10 is virtually determined to be moving with the door open outside, and the car 10 is stopped (S47). Therefore, in practice, it is possible to easily verify the gate opening prevention function in a state where the car 10 is located within the door openable range.

以上のように、実施の形態２によれば、開門発車防止の機能試験において、仮想かご位置信号生成手段から仮想的にかごの位置が戸開走行可能範囲外であることを示すダミー信号を出力することで、実際には戸開走行可能範囲内の状態のままで、容易に検証結果を得ることができる。この結果、戸開状態で戸開走行可能範囲外を走行させるといった非定常的な動作を強制的に行わせる必要なく、開門発車防止の機能試験を確実に行うことができる。   As described above, according to the second embodiment, the dummy car signal indicating that the position of the car is virtually outside the door-openable travel range is output from the virtual car position signal generating means in the function test for preventing the start of departure. As a result, the verification result can be easily obtained while actually remaining in the door openable range. As a result, it is possible to reliably perform a function test for preventing the opening of the gate, without having to force an unsteady operation such as running outside the open door travelable range when the door is open.

実施の形態３．
開門発車防止機能の目的の１つは、適切な位置でかごを停止させることである。このため、検証試験を行った際には、停止したかごの位置を確認することが重要となる。しかしながら、従来、この停止位置が要求される基準を満たすか否かを判定するためには、実際にかごを動かして停止させた後に、かごの位置検出手段により停止位置を測定するといった手間がかかっていた。そこで、本実施の形態３では、開門発車防止の機能試験結果であるかご１０の停止位置を目視で容易に確認できるように、所定の場所に印を付ける場合について説明する。Embodiment 3 FIG.
One of the purposes of the opening gate prevention function is to stop the car at an appropriate position. For this reason, when the verification test is performed, it is important to confirm the position of the stopped car. However, conventionally, in order to determine whether or not the stop position satisfies the required standard, it takes time and effort to measure the stop position by the car position detecting means after actually moving the car to stop. It was. Therefore, in the present third embodiment, a case will be described in which a predetermined place is marked so that the stop position of the car 10 which is the result of the function test for preventing the start of departure can be easily visually confirmed.

図５は、本発明の実施の形態３のエレベータ装置の位置関係を示す説明図である。図５においては、目視確認用として３つの印３０ａ、３０ｂ、３０ｃが設けられている。かご１０が開門発車した場合において、人が昇降路２１の出入口の上枠２２とかご床面２４との間に挟まれることを防止するための基準距離をＬ１とする。このとき、基準距離Ｌ１を確保できる位置を示すために、かごドア１１に付されたマークが印３０ａであり、乗場ドア１２に付されたマークが印３０ｂである。   FIG. 5 is an explanatory diagram showing the positional relationship of the elevator apparatus according to Embodiment 3 of the present invention. In FIG. 5, three marks 30a, 30b, and 30c are provided for visual confirmation. When the car 10 departs from the gate, a reference distance for preventing a person from being caught between the upper frame 22 of the entrance / exit of the hoistway 21 and the car floor 24 is L1. At this time, in order to indicate a position where the reference distance L1 can be secured, the mark attached to the car door 11 is a mark 30a, and the mark attached to the landing door 12 is a mark 30b.

すなわち、開門発車時にかご１０が上昇し、印３０ａが昇降路の出入口の上枠２２に達したとき、あるいは、かご床面２４が印３０ｂに達したときに、かご床面２４と昇降路の出入口の上枠２２との距離がＬ１になったことを意味する。   That is, when the car 10 is raised when the gate is opened and the mark 30a reaches the upper frame 22 of the entrance / exit of the hoistway or when the car floor 24 reaches the mark 30b, the car floor 24 and the hoistway This means that the distance to the upper frame 22 of the doorway is L1.

また、かご１０が開門発車した場合において、かごのつま先保護板１３と昇降路の出入口の下枠２３との間から、人が昇降路２１へ転落することを防ぐための基準距離をＬ２とする。このとき、基準距離Ｌ２を確保できる位置を示すために、乗場ドア１２に付されたマークが印３０ｃである。   Further, when the car 10 departs from the gate, the reference distance for preventing a person from falling into the hoistway 21 from between the toe protection plate 13 of the car and the lower frame 23 of the hoistway entrance / exit is L2. . At this time, in order to indicate a position where the reference distance L2 can be secured, a mark attached to the landing door 12 is a mark 30c.

すなわち、開門発車時にかご１０が上昇し、かごのつま先保護板１３の下端が印３０ｃに達したときに、かごのつま先保護板１３の下端と昇降路の出入口の下枠２３との距離がＬ２になったことを意味する。   That is, when the car 10 rises when the gate starts and the lower end of the toe protection plate 13 of the car reaches the mark 30c, the distance between the lower end of the toe protection plate 13 of the car and the lower frame 23 of the hoistway entrance is L2. Means that

以上のように、実施の形態２によれば、開門発車防止機能の検査において、挟まれや落下を防止するための許容最大距離を示す停止基準位置に、印が設けられている。これにより、開門発車防止機能の検証動作後に、かごを停止させたままで、かごドアと乗場ドアとの相対的な位置関係を、目視により、即座に判断でき、検査結果が良好であるか否かを容易に目視確認することが可能となる。   As described above, according to the second embodiment, the mark is provided at the stop reference position indicating the allowable maximum distance for preventing pinching and dropping in the inspection of the opening gate departure prevention function. As a result, the relative positional relationship between the car door and the landing door can be immediately judged visually and whether the inspection result is good or not, while the car is stopped after the verification operation of the opening gate departure prevention function. Can be easily visually confirmed.

なお、本実施の形態３では、かごが上昇した際の許容最大距離を示す停止基準位置に、印を付した場合を説明した。しかしながら、かごが下降した際の許容最大距離を示す停止基準位置に、印を付すことも可能である。これにより、開門発車で下降した際にも、目視による検査結果の確認を容易に行うことが可能となる。   In the third embodiment, the case has been described in which the stop reference position indicating the allowable maximum distance when the car is raised is marked. However, it is also possible to mark the stop reference position indicating the allowable maximum distance when the car descends. This makes it possible to easily confirm the inspection result by visual inspection even when the vehicle descends at the opening gate.

さらに、本実施の形態３では、許容最大距離を示す停止基準位置を目視確認できるように、印を付した場合を説明した。しかしながら、この印からの距離が分かるように、さらに目盛りを付すこともできる。このような目盛りを付すことにより、許容最大距離までの残距離を容易に、そして即座に、目視確認することができる。   Furthermore, in the third embodiment, the case where a mark is given so that the stop reference position indicating the allowable maximum distance can be visually confirmed has been described. However, further scales can be added so that the distance from this mark can be seen. By attaching such a scale, the remaining distance up to the maximum allowable distance can be easily and immediately visually confirmed.

さらには、先の実施の形態２のように、仮想かご位置としてのダミー信号を用いて開門発車防止の機能試験を行う場合にも、ダミー信号を出力してから停止するまでの相対移動距離を、この目盛りから測定することができ、正確な検証結果を得ることが可能となる。   Furthermore, as in the case of the second embodiment, when performing a gate start prevention function test using a dummy signal as a virtual car position, the relative movement distance from when the dummy signal is output until the vehicle stops is calculated. Therefore, measurement can be performed from this scale, and an accurate verification result can be obtained.
