FIG. 4 is a front view showing the car upper handrail device 10 of FIG. The first to third shaft attachments 24, 34, 44 are provided with a lock mechanism (not shown). When the first to third movable handrail members 22, 32, 42 reach the first to third high handrail positions, they are automatically held at the first to third high handrail positions by the lock mechanism. Further, the state in which the first to third movable handrail members 22, 32, 42 are held at the first to third high handrail positions is released by a lock release operation with respect to the lock mechanism.
　かご上手摺装置１０は、第１～第３の可動手摺部材２２，３２，４２が第１～第３の低手摺位置にあるときに折り畳み状態になり、第１～第３の可動手摺部材２２，３２，４２が第１～第３の高手摺位置にあるときに組み立て状態になる。 The car upper handrail device 10 is in a folded state when the first to third movable handrail members 22, 32, 42 are in the first to third low handrail positions, and the first to third movable handrail members 22 are in the folded state. , 32, 42 are in the assembled state when they are in the first to third high handrail positions.
　かご上手摺装置１０が折り畳み状態になっているときには、図２に示すように、前手摺１１、後手摺１２及び長手摺１３のそれぞれの高さ寸法が互いに同じ寸法Ｈ１になっている。また、かご上手摺装置１０が組み立て状態になっているときには、図４に示すように、前手摺１１、後手摺１２及び長手摺１３のそれぞれの高さ寸法が互いに同じ寸法Ｈ２（Ｈ２＞Ｈ１）になっている。 When the car upper handrail device 10 is in the folded state, as shown in FIG. 2, the height dimensions of the front handrail 11, the rear handrail 12 and the longitudinal slide 13 are the same dimension H1. When the car handrail device 10 is in the assembled state, as shown in FIG. 4, the front handrail 11, the rear handrail 12 and the longitudinal hand 13 have the same height H2 (H2> H1). It has become.
　第１及び第２の可動手摺部材２２，３２は、曲がりやすい索状体１４を介して互いに繋がっている。この例では、第１及び第２の可動手摺部材２２，３２のそれぞれの上端部同士が索状体１４を介して繋がっている。索状体１４としては、例えばロープ、ワイヤ、チェーン、ベルト等が用いられている。 The first and second movable handrail members 22 and 32 are connected to each other via a cord 14 that is easily bent. In this example, the upper ends of the first and second movable handrail members 22 and 32 are connected to each other via the cord-like body 14. As the cord-like body 14, for example, a rope, a wire, a chain, a belt or the like is used.
　索状体１４の長さは、第１の可動手摺部材２２と第２の可動手摺部材３２との間の距離に基づいて設定されている。この例では、第１及び第２の可動手摺部材２２，３２が第１及び第２の低手摺位置にあるとき、及び第１及び第２の可動手摺部材２２，３２が第１及び第２の高手摺位置にあるときに、索状体１４が弛む状態になる。 The length of the cord-like body 14 is set based on the distance between the first movable handrail member 22 and the second movable handrail member 32. In this example, when the first and second movable handrail members 22 and 32 are at the first and second low handrail positions, and when the first and second movable handrail members 22 and 32 are the first and second When in the high handrail position, the cord-like body 14 is in a slack state.
　第１の可動手摺部材２２が第１の低手摺位置から第１の高手摺位置へ変位されるときには、第１の可動手摺部材２２が索状体１４で第２の可動手摺部材３２を引きながら変位されて、第２の可動手摺部材３２が第２の低手摺位置から第２の高手摺位置に近づく方向へ変位される。第１の可動手摺部材２２が索状体１４で第２の可動手摺部材３２を引きながら変位されているときには、第２の可動手摺部材３２の重さによって索状体１４が第１の可動手摺部材２２と第２の可動手摺部材３２との間で張った状態になる。 When the first movable handrail member 22 is displaced from the first low handrail position to the first high handrail position, the first movable handrail member 22 pulls the second movable handrail member 32 with the cord-like body 14. The second movable handrail member 32 is displaced in a direction approaching the second high handrail position from the second low handrail position. When the first movable handrail member 22 is displaced while pulling the second movable handrail member 32 by the cord-like body 14, the cord-like body 14 is moved by the weight of the second movable handrail member 32. The tension is made between the member 22 and the second movable handrail member 32.
　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１０の状態が折り畳み状態になっている。このときには、図１及び図２に示すように、第１～第３の可動手摺部材２２，３２，４２が第１～第３の低手摺位置に保持されている。 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 state of the car upper handrail device 10 is in the folded state. At this time, as shown in FIGS. 1 and 2, the first to third movable handrail members 22, 32, 42 are held at the first to third low handrail positions.
　作業者がかご本体４の上面４ａに乗って保守点検作業を行うときには、例えば最上階の乗場７で操作盤を操作して、エレベータの運転モードを通常運転モードから保守運転モードに切り替えた後、かご本体４の上面４ａが乗場７の床の高さに合うようにかご３を停止させ、最上階の乗場出入口８を開く。 When the operator performs maintenance and inspection work on the upper surface 4a of the car body 4, for example, by operating the operation panel at the hall 7 on the top floor and switching the elevator operation mode from the normal operation mode to the maintenance operation mode, The car 3 is stopped so that the upper surface 4a of the car body 4 matches the floor height of the hall 7, and the hall entrance 8 on the top floor is opened.
　この後、作業者は、最上階の乗場７から、第１及び第３の可動手摺部材２２，４２を持ち上げ、第１及び第３の可動手摺部材２２，４２のそれぞれの位置を第１及び第３の低手摺位置から第１及び第３の高手摺位置へ変位させる。このとき、第２の可動手摺部材３２は、索状体１４を介して第１の可動手摺部材２２に引き上げられながら第２の低手摺位置から第２の高手摺位置に近づく方向へ変位される。第２の可動手摺部材３２が索状体１４を介して第１の可動手摺部材２２に引き上げられているときには、第１の可動手摺部材２２と第２の可動手摺部材３２との間で索状体１４が張った状態になる。 After that, the operator lifts the first and third movable handrail members 22 and 42 from the landing 7 on the top floor, and positions the first and third movable handrail members 22 and 42 in the first and second positions. 3. Displace from the low handrail position 3 to the first and third high handrail positions. At this time, the second movable handrail member 32 is displaced in a direction approaching the second high handrail position from the second low handrail position while being pulled up to the first movable handrail member 22 via the cord-like body 14. . When the second movable handrail member 32 is pulled up to the first movable handrail member 22 via the cord-like body 14, a cord shape is formed between the first movable handrail member 22 and the second movable handrail member 32. The body 14 becomes stretched.
　この後、第１の可動手摺部材２２が第１の高手摺位置に達すると、第１の可動手摺部材２２の位置がロック機構によって第１の高手摺位置に保持され、第３の可動手摺部材４２が第３の高手摺位置に達すると、第３の可動手摺部材４２の位置がロック機構によって第３の高手摺位置に保持される。 Thereafter, when the first movable handrail member 22 reaches the first high handrail position, the position of the first movable handrail member 22 is held at the first high handrail position by the lock mechanism, and the third movable handrail member When 42 reaches the third high handrail position, the position of the third movable handrail member 42 is held at the third high handrail position by the lock mechanism.
　図５は、図２の第１の可動手摺部材２２が第１の低手摺位置から第１の高手摺位置へ変位されたときの第２の可動手摺部材３２の状態を示す正面図である。第１の可動手摺部材２２が第１の低手摺位置から第１の高手摺位置に達すると、第２の可動手摺部材３２は、第１の可動手摺部材２２から索状体１４で吊られて水平面に対して傾斜した状態になる。このとき、第２の可動手摺部材３２の水平面に対する角度は、索状体１４が張った状態で４５°以上に保たれている。 FIG. 5 is a front view showing a state of the second movable handrail member 32 when the first movable handrail member 22 of FIG. 2 is displaced from the first low handrail position to the first high handrail position. When the first movable handrail member 22 reaches the first high handrail position from the first low handrail position, the second movable handrail member 32 is suspended from the first movable handrail member 22 by the cord-like body 14. It becomes a state inclined with respect to the horizontal plane. At this time, the angle of the second movable handrail member 32 with respect to the horizontal plane is maintained at 45 ° or more in a state where the cord-like body 14 is stretched.
　この後、作業者は、乗場７から乗場出入口８及び天井乗り込み口を通ってかご本体４の上面４ａに乗り、傾斜した第２の可動手摺部材３２を第２の高手摺位置へ変位させる。これにより、第２の可動手摺部材３２がロック機構によって第２の高手摺位置に保持され、かご上手摺装置１０の状態が組み立て状態になる。 Thereafter, the worker rides on the upper surface 4a of the car body 4 from the landing 7 through the landing entrance 8 and the ceiling entrance, and displaces the inclined second movable handrail member 32 to the second high handrail position. As a result, the second movable handrail member 32 is held at the second high handrail position by the lock mechanism, and the state of the car upper handrail device 10 becomes the assembled state.
　この後、作業者は、開いている乗場出入口８を閉じた後、保守時かご上操作部を操作してかご３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 operator closes the open hall entrance 8 and then operates the operation unit on the car during maintenance to move the car 3 at a low speed. Thereby, the maintenance inspection work with respect to the apparatus in the hoistway 1 is attained.
　かご本体４の上面４ａ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３を下方へ低速で移動させ、かご本体４の上面４ａが例えば最上階の乗場７の床の高さに合うようにかご３を停止させる。 When the worker on the upper surface 4a of the car body 4 finishes the maintenance and inspection work on the equipment in the hoistway 1, the car 3 is moved downward at a low speed while operating the operation part on the car at the time of maintenance. The car 3 is stopped so that the upper surface 4a of the car matches the height of the floor of the hall 7 on the top floor, for example.
　この後、作業者は、かご上手摺装置１０を組み立てるときと逆の手順でかご上手摺装置１０を折り畳む。即ち、作業者は、後手摺１２のロック機構を操作して第２の可動手摺部材３２の保持を解除し、索状体１４が張った状態になるまで第２の可動手摺部材３２を第２の低手摺位置に向けて変位させ、第２の可動手摺部材３２を水平面に対して傾斜させた状態にする。この後、作業者は、最上階の乗場出入口８を開いて、かご本体４の上面４ａから乗場７へ乗り移る。この後、作業者は、乗場７から、前手摺１１及び長手摺１３のロック機構を操作して第１及び第３の可動手摺部材２２，４２の保持を解除し、第１及び第３の可動手摺部材２２，４２を第１及び第３の低手摺位置へ変位させる。これにより、第２の可動手摺部材３２が第２の低手摺位置へ変位され、かご上手摺装置１０の状態が折り畳み状態になる。この後、乗場出入口８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 operator folds the car upper handrail device 10 in the reverse order of assembling the car upper handrail device 10. In other words, the operator operates the locking mechanism of the rear handrail 12 to release the holding of the second movable handrail member 32 and moves the second movable handrail member 32 to the second state until the cord-like body 14 is stretched. The second movable handrail member 32 is inclined with respect to the horizontal plane. Thereafter, the worker opens the hall entrance 8 on the top floor and transfers to the hall 7 from the upper surface 4 a of the car body 4. Thereafter, the operator operates the lock mechanism of the front handrail 11 and the longitudinal handrail 13 from the landing 7 to release the holding of the first and third movable handrail members 22, 42, and the first and third movable handrails. The handrail members 22 and 42 are displaced to the first and third low handrail positions. As a result, the second movable handrail member 32 is displaced to the second low handrail position, and the state of the car upper handrail device 10 becomes the folded state. Thereafter, the elevator maintenance inspection work is completed by closing the hall entrance 8.
　このようなエレベータのかご上手摺装置１０では、第１の可動手摺部材２２及び第２の可動手摺部材３２が索状体１４を介して互いに繋がっているので、第２の可動手摺部材３２を第１の可動手摺部材２２に連動させることができる。これにより、第１の可動手摺部材２２を第１の低手摺位置から第１の高手摺位置へ変位させると、第２の可動手摺部材３２も第２の低手摺位置から第２の高手摺位置に近づく方向へ自動的に変位させることができる。これにより、前手摺１１及び後手摺１２を別個に組み立てる必要がなくなり、かご上手摺装置１０を組み立てる作業の負担の軽減化を図ることができる。また、索状体１４が曲がりやすいので、前手摺１１の位置に対する後手摺１２の位置が直線上になくても、第１の可動手摺部材２２に第２の可動手摺部材３２を容易にかつより確実に連動させることができる。これにより、前手摺１１と後手摺１２との位置関係の自由度を大きくすることができる。さらに、作業者がかご本体４の上面４ａに乗り込む前に、第２の高手摺位置に近い位置まで第２の可動手摺部材３２を変位させておくことができ、作業者の安全性の向上を図ることができる。 In the elevator car handrail device 10 as described above, the first movable handrail member 22 and the second movable handrail member 32 are connected to each other via the cord-like body 14, and therefore the second movable handrail member 32 is connected to the first movable handrail member 32. One movable handrail member 22 can be interlocked. Thus, when the first movable handrail member 22 is displaced from the first low handrail position to the first high handrail position, the second movable handrail member 32 is also moved from the second low handrail position to the second high handrail position. Can be automatically displaced in a direction approaching. Thereby, it is not necessary to assemble the front handrail 11 and the rear handrail 12 separately, and the burden of the work of assembling the car upper handrail device 10 can be reduced. In addition, since the cord-like body 14 is easily bent, the second movable handrail member 32 can be easily and more easily attached to the first movable handrail member 22 even if the position of the rear handrail 12 with respect to the position of the front handrail 11 is not linear. It can be reliably linked. Thereby, the freedom degree of the positional relationship of the front handrail 11 and the rear handrail 12 can be enlarged. Furthermore, before the operator gets on the upper surface 4a of the car body 4, the second movable handrail member 32 can be displaced to a position close to the second high handrail position, thereby improving the safety of the operator. Can be planned.
　また、第１の可動手摺部材２２が第１の取付軸２３を中心として回動され、第２の可動手摺部材３２が第２の取付軸３３を中心として回動されるので、前手摺１１及び後手摺１２における折り畳み式の構造を簡単にすることができるとともに、第１及び第２の可動手摺部材２２，３２同士の索状体１４による連結も容易にすることができる。 Further, since the first movable handrail member 22 is rotated around the first attachment shaft 23 and the second movable handrail member 32 is rotated around the second attachment shaft 33, the front handrail 11 and The foldable structure of the rear handrail 12 can be simplified, and the connection of the first and second movable handrail members 22 and 32 by the cord-like body 14 can be facilitated.
　また、第１の可動手摺部材２２が第１の低手摺位置にあるときには、第１の可動手摺部材２２の一部が第１の固定手摺部材２１の位置に対してかご３の幅方向内側へ突出し、第１の可動手摺部材２２の残りの一部が第１の固定手摺部材２１の位置に対してかご３の幅方向外側へ突出しているので、かご上手摺装置１０が折り畳み状態であるときに、作業者が第１の固定手摺部材２１よりもかご３の幅方向内側を通って乗り込むことだけでなく、作業者が第１の固定手摺部材２１よりもかご３の幅方向外側を通って乗り込むことも防止することができる。また、第１の可動手摺部材２２が第１の高手摺位置に達したときに、第１の取付軸２３の位置から下方へ延びる第１の可動手摺部材２２の部分の長さを長くすることができ、第１の固定手摺部材２１の側面で受ける第１の可動手摺部材２２の部分の長さを長くすることができる。これにより、前手摺１１が組み立てられたときに、第１の取付軸２３にかかる荷重を小さくすることができ、コストの低減化を図ることができる。 Further, when the first movable handrail member 22 is in the first low handrail position, a part of the first movable handrail member 22 is located inward in the width direction of the car 3 with respect to the position of the first fixed handrail member 21. Since the remaining part of the first movable handrail member 22 protrudes outward in the width direction of the car 3 with respect to the position of the first fixed handrail member 21, the car upper handrail device 10 is in a folded state. In addition, the worker passes through the width direction inner side of the car 3 with respect to the first fixed handrail member 21, and the operator passes through the width direction outer side of the car 3 with respect to the first fixed handrail member 21. You can also prevent getting in. Further, when the first movable handrail member 22 reaches the first high handrail position, the length of the portion of the first movable handrail member 22 extending downward from the position of the first mounting shaft 23 is increased. Thus, the length of the first movable handrail member 22 received on the side surface of the first fixed handrail member 21 can be increased. Thereby, when the front handrail 11 is assembled, the load applied to the first mounting shaft 23 can be reduced, and the cost can be reduced.
