　背面手摺９の可動手摺部材２２は、かご２の幅方向に沿った取付軸２３を介して固定手摺部材２１の上端部に回動可能に取り付けられている。可動手摺部材２２は、取付軸２３の軸線を中心として回動されることにより、固定手摺部材２１の上端部に起立する起立位置と、固定手摺部材２１の上端部に対して倒れた倒れ位置との間で変位可能になっている。背面手摺９の可動手摺部材２２の倒れ位置は、各側面手摺７，８のそれぞれの可動手摺部材１３の倒れ位置よりも低い位置になっている。図１及び図２では、各側面手摺７，８及び背面手摺９のそれぞれの可動手摺部材１３，２２が倒れ位置にあるときの状態を示している。 The movable handrail member 22 of the rear handrail 9 is rotatably attached to the upper end portion of the fixed handrail member 21 through an attachment shaft 23 along the width direction of the car 2. The movable handrail member 22 is rotated about the axis of the mounting shaft 23, thereby standing up at the upper end portion of the fixed handrail member 21, and falling over when tilted with respect to the upper end portion of the fixed handrail member 21. It is possible to displace between. The falling position of the movable handrail member 22 of the rear handrail 9 is lower than the falling position of the movable handrail member 13 of each of the side handrails 7 and 8. FIGS. 1 and 2 show a state where the movable handrail members 13 and 22 of the side handrails 7 and 8 and the back handrail 9 are in the fall position.
　かご上手摺装置６の状態は、各側面手摺７のそれぞれの可動手摺部材１３及び背面手摺９の可動手摺部材２２が起立位置に達することにより組立状態になり、各側面手摺７のそれぞれの可動手摺部材１３及び背面手摺９の可動手摺部材２２が倒れ位置に達することにより折り畳み状態になる。 The state of the car upper handrail device 6 becomes an assembly state when the movable handrail members 13 of the side handrails 7 and the movable handrail member 22 of the rear handrail 9 reach the standing position, and the movable handrails of the respective side handrails 7 are brought into an assembled state. When the movable handrail member 22 of the member 13 and the rear handrail 9 reaches the fall position, the folded state is reached.
　図３は、図１のかご上手摺装置６の状態が組立状態であるときのかご２の上部を示す上面図である。また、図４は、図３のかご２の上部を示す正面図である。各側面手摺７，８のそれぞれの可動手摺部材１３の位置が起立位置になると、図４に示すように、かご２の上面２ａから各側面手摺７，８のそれぞれの可動端部、即ち上端部までの高さが、最大になる。この例では、各可動手摺部材１３が起立位置にあるとき、かご２の上面２ａから各側面手摺７，８のそれぞれの上端部までの高さが８５０ｍｍ以上の高さになっている。 FIG. 3 is a top view showing an upper portion of the car 2 when the state of the car handrail device 6 of FIG. 1 is an assembled state. FIG. 4 is a front view showing the upper part of the car 2 of FIG. When the position of the movable handrail member 13 of each of the side handrails 7 and 8 reaches the upright position, as shown in FIG. 4, the movable end, that is, the upper end of each of the side handrails 7 and 8 from the upper surface 2 a of the car 2. Up to the maximum height. In this example, when each movable handrail member 13 is in the upright position, the height from the upper surface 2a of the car 2 to the respective upper end portions of the side handrails 7 and 8 is 850 mm or more.
　また、背面手摺９の可動手摺部材２２の位置が起立位置になると、かご２の上面２ａから背面手摺９の可動端部、即ち上端部までの高さも、最大になる。この例では、可動手摺部材２２が起立位置にあるとき、かご２の上面２ａから背面手摺９の上端部までの高さが８５０ｍｍ以上の高さになっている。 Further, when the position of the movable handrail member 22 of the rear handrail 9 becomes the standing position, the height from the upper surface 2a of the car 2 to the movable end portion, that is, the upper end portion of the rear handrail 9, is also maximized. In this example, when the movable handrail member 22 is in the standing position, the height from the upper surface 2a of the car 2 to the upper end of the rear handrail 9 is 850 mm or more.
　各側面手摺７，８のそれぞれの可動手摺部材１３は、起立位置から天井乗り込み口側、即ちかご２の内側に倒れることにより倒れ位置に達する。また、各側面手摺７，８のそれぞれの可動手摺部材１３は、倒れ位置にあるとき、図２に示すように、天井乗り込み口の高さ方向中間部に位置しているとともに、天井乗り込み口の幅方向について互いに対向した状態で天井乗り込み口を水平に横切っている。これにより、乗場４からかご２の上面２ａへの作業者の乗り込みが各可動手摺部材１３によって阻止される。 Each movable handrail member 13 of each of the side handrails 7 and 8 reaches the fall position by falling from the standing position to the ceiling entry port side, that is, the inside of the car 2. Further, when the movable handrail member 13 of each of the side handrails 7 and 8 is in the collapsed position, as shown in FIG. 2, the movable handrail member 13 is positioned at the intermediate portion in the height direction of the ceiling entrance, and The ceiling entrance is horizontally traversed while facing each other in the width direction. Accordingly, the movable handrail member 13 prevents the operator from getting on the upper surface 2a of the car 2 from the landing 4.
　各可動手摺部材１３のそれぞれの可動端部の間の距離は、各可動手摺部材１３が起立位置から倒れ位置に変位されることにより連続的に小さくなる。この例では、倒れ位置にあるときの各可動手摺部材１３の可動端部が互いに空間を介して対向しており、倒れ位置にあるときの各可動手摺部材１３の可動端部の間の距離が１００ｍｍ以上になっている。 The distance between the movable end portions of each movable handrail member 13 is continuously reduced by the displacement of each movable handrail member 13 from the standing position to the fall position. In this example, the movable end portions of the movable handrail members 13 when in the tilted position are opposed to each other via a space, and the distance between the movable end portions of the movable handrail members 13 when in the tilted position is It is 100 mm or more.
　一対の可動手摺部材１３のうち、一方には被検出体である検出用板３１が設けられ、他方には検出スイッチ３２が設けられている。検出用板３１は、連結部材である索状体３３を介して一方の可動手摺部材１３の正面２ｂ側の端部に接続されている。索状体３３は、曲がりやすい線状部材である。索状体３３としては、例えばワイヤ、ロープ、チェーン、ベルト等が用いられている。索状体３３の長さは、各可動手摺部材１３が倒れ位置にあるときに検出用板３１が検出スイッチ３２に到達可能で、かつ各可動手摺部材１３の少なくともいずれか一方が倒れ位置から外れているときに検出用板３１が検出スイッチ３２に届かない長さになっている。なお、検出用板３１を可動手摺部材１３に接続する連結部材としては、索状体３３ではなく、例えば棒状部材、板状部材等を用いてもよい。曲がりにくい棒状部材、板状部材等を連結部材として用いた場合、連結部材が可動手摺部材１３に回動可能に取り付けられる。 Among the pair of movable handrail members 13, a detection plate 31 that is a detection target is provided on one side, and a detection switch 32 is provided on the other side. The detection plate 31 is connected to an end portion on the front surface 2b side of one movable handrail member 13 via a cord-like body 33 which is a connecting member. The cord-like body 33 is a linear member that is easily bent. As the cord 33, for example, a wire, a rope, a chain, a belt, or the like is used. The length of the cord 33 is such that the detection plate 31 can reach the detection switch 32 when each movable handrail member 13 is in the fall position, and at least one of the movable handrail members 13 is out of the fall position. The length of the detection plate 31 does not reach the detection switch 32. In addition, as a connecting member for connecting the detection plate 31 to the movable handrail member 13, for example, a rod-like member, a plate-like member, or the like may be used instead of the cord-like body 33. When a bar-like member, a plate-like member, or the like that is difficult to bend is used as the connecting member, the connecting member is rotatably attached to the movable handrail member 13.
　ここで、図５は、図１の検出用板３１及び検出スイッチ３２を示す斜視図である。検出スイッチ３２には、検出用板３１が挿入可能な挿入穴３４が設けられている。各可動手摺部材１３のそれぞれが倒れ位置にある状態では、検出用板３１が検出スイッチ３２の挿入穴３４内に挿入可能になっている。検出用板３１は、挿入穴３４内に挿入されることにより検出スイッチ３２に保持される。 Here, FIG. 5 is a perspective view showing the detection plate 31 and the detection switch 32 of FIG. The detection switch 32 is provided with an insertion hole 34 into which the detection plate 31 can be inserted. In a state where each movable handrail member 13 is in the collapsed position, the detection plate 31 can be inserted into the insertion hole 34 of the detection switch 32. The detection plate 31 is held by the detection switch 32 by being inserted into the insertion hole 34.
　各可動手摺部材１３が倒れ位置にあり、検出用板３１が検出スイッチ３２の挿入穴３４に挿入されている状態では、図２に示すように、連結部材である索状体３３が一方の可動手摺部材１３と他方の可動手摺部材１３との間の空間に張られている。これにより、一方の可動手摺部材１３と他方の可動手摺部材１３との間の空間を作業者が通過することが索状体３３によって阻止され、乗場４からかご２の上面２ａへの作業者の乗り込みが索状体３３によってさらに確実に阻止される。 In a state where each movable handrail member 13 is in the tilted position and the detection plate 31 is inserted into the insertion hole 34 of the detection switch 32, as shown in FIG. It is stretched in a space between the handrail member 13 and the other movable handrail member 13. As a result, the cord 33 prevents the worker from passing through the space between the one movable handrail member 13 and the other movable handrail member 13, and the worker moves from the landing 4 to the upper surface 2 a of the car 2. The boarding is prevented more reliably by the cord 33.
　検出スイッチ３２は、検出用板３１が挿入穴３４に挿入されると検出用板３１を検出して検出信号を制御装置へ出力し、検出用板３１が挿入穴３４から抜かれると検出用板３１を検出しなくなって検出信号の出力を停止する。制御装置は、検出スイッチ３２からの情報に基づいて、エレベータの運転を制御する。通常運転モードでのサービス運転は、制御装置が検出スイッチ３２からの検出信号を受けているときに制御装置によって許可される。検出スイッチ３２から制御装置への検出信号の出力が停止すると、サービス運転が不可能になるとともに、保守運転モードでの保守時かご上操作部の操作による運転が可能になる。 The detection switch 32 detects the detection plate 31 when the detection plate 31 is inserted into the insertion hole 34 and outputs a detection signal to the control device. When the detection plate 31 is removed from the insertion hole 34, the detection switch 31 detects the detection plate 31. 31 is no longer detected and the output of the detection signal is stopped. The control device controls the operation of the elevator based on information from the detection switch 32. Service operation in the normal operation mode is permitted by the control device when the control device receives a detection signal from the detection switch 32. When output of the detection signal from the detection switch 32 to the control device stops, service operation becomes impossible and operation by operating the operation unit on the car during maintenance in the maintenance operation mode becomes possible.
　ここで、図６は、図５の検出用板３１が検出スイッチ３２から外れている状態を示す模式図である。また、図７は、図６の検出用板３１が検出スイッチ３２の挿入穴３４に挿入されている状態を示す模式図である。検出スイッチ３２は、挿入穴３４内に露出する２つの端子３２ａ，３２ｂを有している。２つの端子３２ａ，３２ｂは、互いに離れた位置で挿入穴３４内に露出している。 Here, FIG. 6 is a schematic view showing a state in which the detection plate 31 of FIG. FIG. 7 is a schematic diagram showing a state where the detection plate 31 of FIG. 6 is inserted into the insertion hole 34 of the detection switch 32. The detection switch 32 has two terminals 32 a and 32 b exposed in the insertion hole 34. The two terminals 32a and 32b are exposed in the insertion hole 34 at positions separated from each other.
　検出用板３１が挿入穴３４内に挿入されると、挿入穴３４内に露出している２つの端子３２ａ，３２ｂに検出用板３１が接触し、２つの端子３２ａ，３２ｂが検出用板３１を介して電気的に短絡する。検出スイッチ３２は、２つの端子３２ａ，３２ｂが検出用板３１によって短絡することにより、検出用板３１を検出する。即ち、各可動手摺部材１３のそれぞれが倒れ位置にある状態では、検出用板３１を挿入穴３４に挿入することによって検出スイッチ３２が検出用板３１を検出可能になっている。 When the detection plate 31 is inserted into the insertion hole 34, the detection plate 31 contacts the two terminals 32 a and 32 b exposed in the insertion hole 34, and the two terminals 32 a and 32 b are connected to the detection plate 31. Is electrically shorted through. The detection switch 32 detects the detection plate 31 when the two terminals 32 a and 32 b are short-circuited by the detection plate 31. That is, in a state where each movable handrail member 13 is in the tilted position, the detection switch 32 can detect the detection plate 31 by inserting the detection plate 31 into the insertion hole 34.
　検出用板３１が接続された一方の側面手摺７の固定手摺部材１２には、検出用板３１が着脱可能になっている。検出用板３１は、図４に示すように、一方の側面手摺７の可動手摺部材１３が起立位置にあるときに、固定手摺部材１２に取り付けられる。 The detection plate 31 is attachable to and detachable from the fixed handrail member 12 of the one side handrail 7 to which the detection plate 31 is connected. As shown in FIG. 4, the detection plate 31 is attached to the fixed handrail member 12 when the movable handrail member 13 of the one side handrail 7 is in the standing position.
　図８は、図７の検出用板３１が一方の側面手摺７の固定手摺部材１２に取り付けられている状態を示す拡大図である。一方の側面手摺７の固定手摺部材１２には、検出用板３１を固定手摺部材１２に取り付ける取付具である蝶ボルト３５が設けられている。検出用板３１には、蝶ボルト３５のボルト部が挿入可能な切欠部３６が設けられている。検出用板３１は、切欠部３６に蝶ボルト３５のボルト部を挿入した状態で蝶ボルト３５が締め込まれることにより、固定手摺部材１２に取り付けられている。一方の側面手摺７の固定手摺部材１２に取り付けられている検出用板３１は、蝶ボルト３５を緩めることにより固定手摺部材１２から外れる。 FIG. 8 is an enlarged view showing a state in which the detection plate 31 of FIG. 7 is attached to the fixed handrail member 12 of one side handrail 7. The fixed handrail member 12 of one side handrail 7 is provided with a butterfly bolt 35 that is an attachment for attaching the detection plate 31 to the fixed handrail member 12. The detection plate 31 is provided with a notch 36 into which the bolt portion of the butterfly bolt 35 can be inserted. The detection plate 31 is attached to the fixed handrail member 12 by tightening the butterfly bolt 35 with the bolt portion of the butterfly bolt 35 inserted into the notch 36. The detection plate 31 attached to the fixed handrail member 12 of the one side handrail 7 is detached from the fixed handrail member 12 by loosening the butterfly bolt 35.
　次に、エレベータの保守点検作業の手順について説明する。エレベータのサービス運転は、通常運転モードで行われる。エレベータが通常運転モードで運転されているときには、かご上手摺装置６が折り畳み状態になっているとともに、検出用板３１が検出スイッチ３２の挿入穴３４に挿入されている。 Next, the procedure for elevator maintenance and inspection will be described. The service operation of the elevator is performed in the normal operation mode. When the elevator is operated in the normal operation mode, the car handrail device 6 is in a folded state, and the detection plate 31 is inserted into the insertion hole 34 of the detection switch 32.
　作業者がかご２の上面２ａに乗って保守点検作業を行うときには、例えば最上階で乗場４の操作盤を操作して、かご２の上面２ａが乗場４の床の高さに合うようにかご２を停止させた後、乗場出入口５を開く。このとき、各側面手摺７，８のそれぞれの可動手摺部材１３が天井乗り込み口の高さ方向中間部に配置され、索状体３３が各可動手摺部材１３間に連結されていることから、各可動手摺部材１３及び索状体３３が邪魔になって作業者が乗場４からかご２の上面２ａに乗り込めないようになっている。 When an operator performs maintenance and inspection work on the upper surface 2a of the car 2, for example, the car is operated so that the upper surface 2a of the car 2 matches the height of the floor of the hall 4 by operating the operation panel of the hall 4 on the top floor. After stopping 2, open the hall entrance 5. At this time, each movable handrail member 13 of each of the side handrails 7 and 8 is disposed at the intermediate portion in the height direction of the ceiling entry port, and the cord-like body 33 is connected between each movable handrail member 13. The movable handrail member 13 and the cord-like body 33 are in the way so that the worker cannot get on the upper surface 2 a of the car 2 from the landing 4.
　この後、作業者は、最上階の乗場４からの作業によって、検出スイッチ３２から検出用板３１を外し、各側面手摺７，８のそれぞれの可動手摺部材１３を倒れ位置から起立位置へ持ち上げる。検出スイッチ３２から検出用板３１が外れると、検出スイッチ３２から制御装置への検出信号の出力が停止する。これにより、サービス運転が不可能になり、保守運転モードでの保守時かご上操作部の操作による運転が可能になる。この後、一方の側面手摺７の固定手摺部材１２に検出用板３１を蝶ボルト３５で留める。 Thereafter, the operator removes the detection plate 31 from the detection switch 32 and lifts the movable handrail members 13 of the side handrails 7 and 8 from the fall position to the standing position by work from the landing 4 on the top floor. When the detection plate 31 is removed from the detection switch 32, the output of the detection signal from the detection switch 32 to the control device stops. As a result, service operation becomes impossible, and operation by operating the operation unit on the car during maintenance in the maintenance operation mode becomes possible. Thereafter, the detection plate 31 is fastened to the fixed handrail member 12 of one side handrail 7 with the butterfly bolt 35.
　この後、作業者は、乗場４から乗場出入口５及び天井乗り込み口を通ってかご２の上面２ａに乗り込み、背面手摺９の可動手摺部材２２を倒れ位置から起立位置へ持ち上げる。これにより、かご上手摺装置６の状態が組立状態になる。 After this, the worker enters the upper surface 2a of the car 2 from the landing 4 through the landing entrance 5 and the ceiling entrance, and lifts the movable handrail member 22 of the rear handrail 9 from the fall position to the standing position. As a result, the state of the car handrail device 6 becomes the assembled state.
　この後、作業者は、開いている乗場出入口５を閉じた後、保守時かご上操作部を操作してかご２を低速で移動させる。これにより、昇降路１内の機器に対する保守点検作業が可能になる。 After this, the worker closes the open hall entrance 5 and then operates the operation unit on the car for maintenance to move the car 2 at a low speed. Thereby, the maintenance inspection work with respect to the apparatus in the hoistway 1 is attained.
　かご２の上面２ａに乗った作業者は、昇降路１内の機器に対する保守点検作業が終わると、保守時かご上操作部を操作しながらかご２を下方へ低速で移動させ、かご２の上面２ａが例えば最上階の乗場４の床の高さに合うようにかご２を停止させる。この後、背面手摺９の可動手摺部材２２を起立位置から倒れ位置へ変位させてから、最上階の乗場出入口５を開いて、かご２の上面２ａから乗場４へ乗り移る。 When the worker on the upper surface 2a of the car 2 finishes the maintenance and inspection work on the equipment in the hoistway 1, the car 2 is moved downward at a low speed while operating the operation unit on the car at the time of maintenance. The car 2 is stopped so that 2a matches the floor height of the hall 4 on the top floor, for example. Thereafter, the movable handrail member 22 of the rear handrail 9 is displaced from the standing position to the fall position, and then the landing doorway 5 on the uppermost floor is opened, and the transfer is made from the upper surface 2a of the car 2 to the landing 4.
　この後、作業者は、乗場４から、各可動手摺部材１３を起立位置から倒れ位置へ変位させる。これにより、かご上手摺装置６の状態が折り畳み状態になる。この後、一方の側面手摺７の固定手摺部材１２から外した検出用板３１を検出スイッチ３２の挿入穴３４に差し込む。これにより、索状体３３が一方の可動手摺部材１３と他方の可動手摺部材１３との間に渡った状態になる。この後、乗場出入口５を閉じることにより、エレベータの保守点検作業が終了する。 After this, the worker displaces each movable handrail member 13 from the standing position 4 to the fall position from the landing 4. Thereby, the state of the car upper handrail device 6 becomes the folded state. Thereafter, the detection plate 31 removed from the fixed handrail member 12 of one side handrail 7 is inserted into the insertion hole 34 of the detection switch 32. As a result, the cord-like body 33 is in a state where it extends between one movable handrail member 13 and the other movable handrail member 13. Thereafter, the elevator maintenance inspection work is completed by closing the hall entrance 5.
　このようなエレベータ装置では、倒れ位置にあるときの各可動手摺部材１３が、天井乗り込み口の幅方向について互いに対向した状態で天井乗り込み口の高さ方向中間部に配置されているので、作業者は、各可動手摺部材１３を起立位置に変位させなければ乗場４からかご２の上面２ａに乗り込めないようになり、各側面手摺７，８を立てる前に作業者がかご２上に乗り込むことの防止を図ることができる。また、各可動手摺部材１３のそれぞれが倒れ位置にある状態では、検出スイッチ３２が検出用板３１を検出可能になっているので、検出スイッチ３２による検出用板３１の検出を停止させなければ、作業者がかご２の上面２ａに乗り込めないようにすることができる。これにより、通常のサービス運転が保守点検時に誤って行われることをより確実に防止することができるとともに、保守運転モードでの保守時かご上操作部の操作による運転をより確実に行うことができる。 In such an elevator apparatus, the movable handrail members 13 when in the fall position are arranged in the height direction intermediate portion of the ceiling entry port in a state of facing each other in the width direction of the ceiling entry port. If the movable handrail members 13 are not displaced to the standing position, they cannot get on the upper surface 2a of the car 2 from the landing 4, and the operator can get on the car 2 before raising the side handrails 7 and 8. Prevention can be achieved. Further, in the state where each of the movable handrail members 13 is in the collapsed position, the detection switch 32 can detect the detection plate 31. Therefore, unless the detection of the detection plate 31 by the detection switch 32 is stopped, It is possible to prevent an operator from getting on the upper surface 2a of the car 2. As a result, it is possible to more reliably prevent a normal service operation from being mistakenly performed during maintenance and inspection, and it is possible to more reliably perform an operation by operating the operation unit on the car during maintenance in the maintenance operation mode. .
　また、検出用板３１は、索状体３３を介して一方の側面手摺７の可動手摺部材１３に接続されているので、倒れ位置にあるときの各可動手摺部材１３だけでなく、索状体３３によっても、作業者がかご２上に乗り込むことを防止することができ、各側面手摺７，８を立てる前に作業者がかご２上に乗り込むことの防止をさらに確実に図ることができる。 Further, since the detection plate 31 is connected to the movable handrail member 13 of the one side rail 7 via the cord-like body 33, not only the movable handrail members 13 when in the fall position but also the cord-like body. 33 can also prevent the worker from getting on the car 2, and can more reliably prevent the operator from getting on the car 2 before raising the side handrails 7 and 8.
　また、かご２の上面２ａから固定手摺部材１２の上端部までの高さは、４００ｍｍ～７００ｍｍの範囲内の高さであるので、倒れ位置にあるときの可動手摺部材１３の位置の高さを、作業者が可動手摺部材１３を乗り越えることが困難な位置の高さにすることができる。これにより、各側面手摺７，８を立てる前に作業者がかご２上に乗り込むことの防止をさらに確実に図ることができる。 Further, since the height from the upper surface 2a of the car 2 to the upper end of the fixed handrail member 12 is in the range of 400 mm to 700 mm, the height of the position of the movable handrail member 13 when it is in the fall position is set. The height of the position where it is difficult for the operator to get over the movable handrail member 13 can be obtained. Accordingly, it is possible to further reliably prevent the worker from getting on the car 2 before raising the side handrails 7 and 8.
　なお、上記の例では、一方の側面手摺７の固定手摺部材１２に検出用板３１が着脱可能になっているが、これに限定されず、例えば、一方の側面手摺７の可動手摺部材１３又はかご２自体に検出用板３１が着脱可能になっていてもよい。 In the above example, the detection plate 31 is attachable to and detachable from the fixed handrail member 12 of one side handrail 7, but is not limited to this, for example, the movable handrail member 13 of one side handrail 7 or The detection plate 31 may be detachable from the car 2 itself.
　実施の形態２．
　図９は、この発明の実施の形態２によるエレベータ装置を示す上面図である。また、図１０は、図９のかご２の上部を示す正面図である。さらに、図１１は、図９のかご上手摺装置６の状態が組立状態であるときのかご２の上部を示す上面図である。さらにまた、図１２は、図１１のかご２の上部を示す正面図である。一方の側面手摺７における可動手摺部材１３の正面２ｂ側の端部には、索状体回収装置４１が設けられている。索状体回収装置４１は、索状体３３を巻き取る巻取軸を有している。検出用板３１及び索状体３３は、索状体３３が巻取軸に巻き取られることにより索状体回収装置４１に収容される。索状体回収装置４１から繰り出される索状体３３の長さは、各可動手摺部材１３が倒れ位置にあるときに索状体３３が各可動手摺部材１３のそれぞれに連続して掛かる長さになっている。 Embodiment 2. FIG.
FIG. 9 is a top view showing an elevator apparatus according to Embodiment 2 of the present invention. FIG. 10 is a front view showing the upper part of the car 2 of FIG. Further, FIG. 11 is a top view showing an upper portion of the car 2 when the state of the car handrail device 6 of FIG. 9 is an assembled state. FIG. 12 is a front view showing the upper part of the car 2 of FIG. At one end of the side handrail 7 on the front 2b side of the movable handrail member 13, a cord-like body recovery device 41 is provided. The cord recovery apparatus 41 has a winding shaft that winds the cord 33. The detection plate 31 and the cord-like body 33 are accommodated in the cord-like body recovery device 41 when the cord-like body 33 is wound around the winding shaft. The length of the cord 33 fed out from the cord collection device 41 is such that the cord 33 is continuously applied to each movable handrail member 13 when each movable handrail member 13 is in the collapsed position. It has become.
　各可動手摺部材１３のそれぞれの回動端部、即ち上端部に位置する横アングル材には、図９に示すように、複数の突起４２が固定されている。各突起４２は、可動手摺部材１３の横アングル材の長手方向、即ちかご２の奥行き方向について互いに間隔を置いて配置されている。各突起４２には、索状体３３及び検出用板３１が通過可能な通し穴が形成されている。 As shown in FIG. 9, a plurality of protrusions 42 are fixed to the horizontal angle members located at the respective rotating end portions, that is, the upper end portions of the movable handrail members 13. The protrusions 42 are arranged at intervals from each other in the longitudinal direction of the lateral angle member of the movable handrail member 13, that is, in the depth direction of the car 2. Each projection 42 is formed with a through-hole through which the cord-like body 33 and the detection plate 31 can pass.
　検出用板３１が挿入穴３４に挿入されて検出スイッチ３２が検出用板３１を検出している状態では、索状体３３は、各突起４２の通し穴に順次通された状態で、一方及び他方の可動手摺部材１３のそれぞれの横アングル材に掛けられている。また、検出用板３１が挿入穴３４に挿入されて検出スイッチ３２が検出用板３１を検出している状態では、可動手摺部材１３に掛かる位置をかご２の奥行き方向についてずらしながら、一方及び他方の可動手摺部材１３のそれぞれの横アングル材に連続して交互に掛けられている。他の構成は実施の形態１と同様である。 In a state where the detection plate 31 is inserted into the insertion hole 34 and the detection switch 32 detects the detection plate 31, the cord 33 is sequentially passed through the through holes of the protrusions 42, and It is hung on each lateral angle member of the other movable handrail member 13. Further, in a state where the detection plate 31 is inserted into the insertion hole 34 and the detection switch 32 detects the detection plate 31, the position on the movable handrail member 13 is shifted in the depth direction of the car 2, and The movable handrail members 13 are alternately and continuously hung on the respective lateral angle members. Other configurations are the same as those in the first embodiment.
　エレベータの保守点検作業については、各側面手摺７，８のそれぞれの可動手摺部材１３を倒れ位置から起立位置へ持ち上げるときの作業と、索状体３３を検出スイッチ３２の挿入穴３４に差し込むときの作業とを除いて、実施の形態１と同様である。 As for the maintenance and inspection work of the elevator, the work for lifting the movable handrail members 13 of the side handrails 7 and 8 from the fall position to the standing position and the insertion of the cord 33 into the insertion hole 34 of the detection switch 32 are performed. Except for work, it is the same as in the first embodiment.
　各側面手摺７，８のそれぞれの可動手摺部材１３を倒れ位置から起立位置へ持ち上げるときには、作業者は、乗場４からの作業によって検出スイッチ３２から検出用板３１を外した後、索状体回収装置４１によって索状体３３を巻取軸に巻き取りながら、一方及び他方の可動手摺部材１３から索状体３３を順次外し、索状体３３及び検出用板３１を索状体回収装置４１に収容する。この後、各側面手摺７，８のそれぞれの可動手摺部材１３を倒れ位置から起立位置へ持ち上げる。 When lifting the movable handrail member 13 of each of the side handrails 7 and 8 from the fall position to the standing position, the operator removes the detection plate 31 from the detection switch 32 by work from the landing 4, and then retrieves the cords. While winding the cord 33 around the winding shaft by the device 41, the cord 33 is sequentially removed from the one and the other movable handrail members 13, and the cord 33 and the detection plate 31 are attached to the cord collecting device 41. Accommodate. Thereafter, the movable handrail members 13 of the side handrails 7 and 8 are lifted from the fall position to the standing position.
　また、索状体３３を検出スイッチ３２の挿入穴３４に差し込むときには、索状体回収装置４１から検出用板３１及び索状体３３を引き出した後、各突起４２の通し穴に検出用板３１及び索状体３３を順次通しながら、索状体３３を一方及び他方の可動手摺部材１３に連続して交互に掛けてから、検出スイッチ３２の挿入穴３４に検出用板３１を差し込む。 Further, when the cord 33 is inserted into the insertion hole 34 of the detection switch 32, after the detection plate 31 and the cord 33 are pulled out from the cord collection device 41, the detection plate 31 is inserted into the through hole of each protrusion 42. Then, while passing the cord-like body 33 sequentially, the cord-like bodies 33 are alternately and continuously hung on the one and the other movable handrail members 13, and then the detection plate 31 is inserted into the insertion hole 34 of the detection switch 32.
　このようなエレベータ装置では、検出スイッチ３２が検出用板３１を検出しているときの索状体３３が、可動手摺部材１３に掛かる位置をかご２の奥行き方向についてずらしながら、一方及び他方の可動手摺部材１３に連続して交互に掛けられているので、各可動手摺部材１３間に張られる索状体３３の範囲を広くすることができ、各側面手摺７，８を立てる前に作業者がかご２上に乗り込むことの防止をさらに確実に図ることができる。 In such an elevator apparatus, the cable 33 when the detection switch 32 detects the detection plate 31 shifts the position on the movable handrail member 13 in the depth direction of the car 2 while moving the one and the other movable. Since it is continuously and alternately hung on the handrail member 13, the range of the cord-like body 33 stretched between the movable handrail members 13 can be widened, and the operator can set up the side handrails 7 and 8 before standing up. It is possible to more reliably prevent the car 2 from getting on.
　また、各可動手摺部材１３に複数の突起４２が設けられ、索状体３３及び検出用板３１が通過可能な通し穴が各突起４２に設けられているので、索状体３３が可動手摺部材１３に掛けられている位置がずれることを防止することができる。 In addition, each movable handrail member 13 is provided with a plurality of protrusions 42, and each protrusion 42 is provided with a through hole through which the cable-like body 33 and the detection plate 31 can pass. The position hung on 13 can be prevented from shifting.
　なお、上記の例では、索状体３３が通される通し穴が設けられた複数の突起４２が可動手摺部材１３に設けられているが、索状体３３が掛かる可動手摺部材１３の部分に窪みを設けてもよい。このようにしても、可動手摺部材１３に掛かる索状体３３が窪みに嵌ることにより索状体３３をすれにくくすることができる。また、複数の突起４２はなくてもよい。このようにしても、一方及び他方の可動手摺部材１３に索状体３３を連続して交互に掛けることができる。 In the above example, the plurality of protrusions 42 provided with through holes through which the cord-like body 33 is passed are provided on the movable handrail member 13, but the portion of the movable handrail member 13 on which the cord-like body 33 is hooked is provided. You may provide a hollow. Even if it does in this way, it can make it difficult to slip the cord-like body 33 because the cord-like body 33 concerning the movable handrail member 13 fits into a hollow. Further, the plurality of protrusions 42 may not be provided. Even in this way, the cord-like bodies 33 can be alternately and continuously hung on the one and the other movable handrail members 13.
　また、各上記実施の形態では、検出スイッチ３２が２つの端子３２ａ，３２ｂを有し、２つの端子３２ａ，３２ｂが検出用板３１を介して短絡することにより、検出スイッチ３２が検出用板３１を検出するようになっているが、検出スイッチ３２が、２つの端子３２ａ，３２ｂに接触したり離れたりする可動接点をさらに有するようにし、検出用板３１を挿入穴３４に挿入することにより、検出用板３１を可動接点に接触させて、２つの端子３２ａ，３２ｂに接触する方向へ可動接点を検出用板３１で押し込むようにしてもよい。この場合、２つの端子３２ａ，３２ｂが可動接点を介して短絡することにより、検出スイッチ３２が検出用板３１を検出する。 In each of the above embodiments, the detection switch 32 has two terminals 32a and 32b, and the two terminals 32a and 32b are short-circuited via the detection plate 31, whereby the detection switch 32 is detected by the detection plate 31. However, the detection switch 32 further includes a movable contact that contacts or separates from the two terminals 32a and 32b, and the detection plate 31 is inserted into the insertion hole 34. The detection plate 31 may be brought into contact with the movable contact, and the movable contact may be pushed by the detection plate 31 in a direction in which the detection plate 31 comes into contact with the two terminals 32a and 32b. In this case, the detection switch 32 detects the detection plate 31 when the two terminals 32a and 32b are short-circuited via the movable contact.
　また、各上記実施の形態では、検出スイッチ３２が検出する被検出体として検出用板３１が用いられているが、被検出体の形状はこれに限定されない。例えば、被検出体の形状を棒状としてもよい。 In each of the above-described embodiments, the detection plate 31 is used as the detected object detected by the detection switch 32, but the shape of the detected object is not limited to this. For example, the shape of the detected object may be a rod shape.
　また、各上記実施の形態では、倒れ位置にあるときの各可動手摺部材１３間の距離が１００ｍｍ以上になっているが、倒れ位置にあるときの各可動手摺部材１３間の距離を１００ｍｍよりも短い距離にしてもよいし、倒れ位置にあるときの各可動手摺部材１３同士が接触するようにしてもよい。このようにすれば、例えば、一方の可動手摺部材１３に検出用板３１を固定するとともに、他方の可動手摺部材１３に検出スイッチ３２を固定し、各可動手摺部材１３が起立位置から倒れ位置へ変位されることにより、検出用板３１が検出スイッチ３２の挿入穴３４に自動的に挿入されるようにすることができる。これにより、索状体３３をなくすことができる。また、この場合、検出スイッチ３２は、検出用板３１を接触により検出する接触式のスイッチとしてもよいし、検出用板３１を非接触で検出する近接スイッチにしてもよい。 Moreover, in each said embodiment, although the distance between each movable handrail member 13 in the fall position is 100 mm or more, the distance between each movable handrail member 13 in the fall position is more than 100 mm. The distance may be a short distance, or the movable handrail members 13 may be in contact with each other when in the fall position. In this way, for example, the detection plate 31 is fixed to one movable handrail member 13 and the detection switch 32 is fixed to the other movable handrail member 13 so that each movable handrail member 13 is moved from the standing position to the fall position. By being displaced, the detection plate 31 can be automatically inserted into the insertion hole 34 of the detection switch 32. Thereby, the cord-like body 33 can be eliminated. In this case, the detection switch 32 may be a contact type switch that detects the detection plate 31 by contact, or may be a proximity switch that detects the detection plate 31 in a non-contact manner.
