Description

エレベータの作業補助装置Elevator work aid
　本開示は、昇降路内に設けられるエレベータの作業補助装置に関するものである。 The present disclosure relates to an elevator work assistance device provided in a hoistway.
　従来、昇降路の底部における作業者の作業空間を確保するために、支柱が昇降路の底部に設けられたエレベータが知られている。支柱は、エレベータの通常運転時には昇降路の底部に横たわっている。また、支柱は、エレベータの保守時に作業者によって昇降路の底部に立てられる。支柱が昇降路の底部に立てられている状態では、かごが最下階よりも下方へ移動すると、かごが支柱に当たってかごの下方への移動が阻止される（例えば特許文献１参照）。 Conventionally, an elevator is known in which a pillar is provided at the bottom of the hoistway in order to secure a working space for workers at the bottom of the hoistway. The struts lie at the bottom of the hoistway during normal operation of the elevator. Also, the stanchion is erected at the bottom of the hoistway by an operator during maintenance of the elevator. In a state in which the pillars are erected on the bottom of the hoistway, when the car moves below the lowest floor, the car hits the pillars and is prevented from moving downward (see Patent Document 1, for example).
国際公開第９９／４７４４７号WO99/47447
　しかし、特許文献１に示されている従来のエレベータでは、エレベータの保守時に作業者が昇降路の底部に入って支柱を立てる必要がある。従って、昇降路の底部における作業者の作業負担が大きくなってしまう。 However, in the conventional elevator shown in Patent Document 1, it is necessary for a worker to enter the bottom of the hoistway and erect a support during maintenance of the elevator. Therefore, the work burden on the worker at the bottom of the hoistway increases.
　本開示は、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、昇降路の底部における作業者の作業負担の軽減を図ることができるエレベータの作業補助装置を得ることを目的とする。 The present disclosure has been made to solve the above problems, and aims to obtain an elevator work assistance device that can reduce the work burden on workers at the bottom of the hoistway.
　本開示によるエレベータの作業補助装置は、かごが移動する昇降路内に固定される支持具と、支持具に支持されており、昇降路の高さ方向において昇降路の底部とかごとの間に配置されるかご受け構造体と、かご受け構造体に接続されており、乗場敷居に接続される索状体とを備え、支持具は、昇降路を上から見たとき、かごの領域から外れた位置に固定されるようになっており、かご受け構造体の状態は、かご受け構造体が支持具から乗場敷居に達する敷居到達状態と、かご受け構造体が乗場敷居から外れる退避状態との間で変化可能になっており、昇降路を上から見たとき、かご受け構造体の状態が敷居到達状態になることによりかご受け構造体の一部がかごの領域に重なり、かご受け構造体の状態が退避状態になることによりかご受け構造体がかごの領域から外れる。 The elevator work assist device according to the present disclosure includes a support fixed in a hoistway in which a car moves, and a support supported by the support and arranged between the bottom of the hoistway and the car in the height direction of the hoistway. and a ligament connected to the car receiving structure and connected to the landing sill, the support being out of the area of the car when viewed from above the hoistway. The state of the car receiving structure is between a threshold reaching state in which the car receiving structure reaches the landing threshold from the support and a retracted state in which the car receiving structure is removed from the landing threshold. When the hoistway is viewed from above, the state of the car support structure reaches the threshold, so that part of the car support structure overlaps the area of the car, and the car support structure By changing the state to the retracted state, the car receiving structure moves out of the car area.
　本開示によるエレベータの作業補助装置によれば、昇降路の底部における作業者の作業負担の軽減を図ることができる。 According to the elevator work assistance device according to the present disclosure, it is possible to reduce the work load on the worker at the bottom of the hoistway.

In this embodiment, the car support structure 9 is arranged at a height that matches the floor surface of the lowest floor.
　かご受け構造体９は、伸縮可能な長尺部材である。また、かご受け構造体９は、複数の第１リンク部材９１と、複数の第２リンク部材９２とを有している。複数の第１リンク部材９１及び複数の第２リンク部材９２は、直列に連結された複数のリンク部材である。即ち、かご受け構造体９は、複数の第１リンク部材９１及び複数の第２リンク部材９２が直列に連結されたリンク部材連結体となっている。かご受け構造体９では、第１リンク部材９１と第２リンク部材９２とが交互に直列に連結されている。 The car support structure 9 is a stretchable elongated member. The cage receiving structure 9 also has a plurality of first link members 91 and a plurality of second link members 92 . The multiple first link members 91 and the multiple second link members 92 are multiple link members connected in series.

In the cage receiving structure 9, the first link members 91 and the second link members 92 are alternately connected in series.
　互いに隣り合う２つのリンク部材である第１リンク部材９１及び第２リンク部材９２は、連結軸９３によって互いに連結されている。連結軸９３は、第１リンク部材９１及び第２リンク部材９２のそれぞれの長手方向の端部同士を連結している。互いに隣り合う２つのリンク部材である第１リンク部材９１及び第２リンク部材９２同士は、連結軸９３を中心に回転可能になっている。連結軸９３は、第１リンク部材９１及び第２リンク部材９２のそれぞれの長手方向に直交している。ここで、連結軸９３に沿った方向をかご受け構造体９の幅方向とする。本実施の形態では、かご受け構造体９の幅方向を水平にした状態でかご受け構造体９が支持具１０に支持されている。 A first link member 91 and a second link member 92 , which are two link members adjacent to each other, are connected to each other by a connecting shaft 93 .

　各第１リンク部材９１は、棒状の部材である。各第２リンク部材９２は、一対のリンク板９２１を有している。一対のリンク板９２１は、かご受け構造体９の幅方向において互いに対向している。 Each first link member 91 is a rod-shaped member. Each second link member 92 has a pair of link plates 921 . The pair of link plates 921 face each other in the width direction of the car support structure 9 .
　第１リンク部材９１と第２リンク部材９２との連結部分では、一対のリンク板９２１の間に第１リンク部材９１が挿入されている。また、第１リンク部材９１と第２リンク部材９２との連結部分では、連結軸９３が第１リンク部材９２及び一対のリンク板９２１を貫通している。 The first link member 91 is inserted between a pair of link plates 921 at the connecting portion between the first link member 91 and the second link member 92 . Moreover, the connecting shaft 93 penetrates the first link member 92 and the pair of link plates 921 at the connecting portion between the first link member 91 and the second link member 92 .
　かご受け構造体９の一端部は、敷居側端部となっている。かご受け構造体９の他端部は、反敷居側端部となっている。かご受け構造体９の敷居側端部の位置は、かご受け構造体９の反敷居側端部の位置よりも乗場敷居２３に近い位置となっている。かご受け構造体９の反敷居側端部は、支持具１０に取り付けられている。本実施の形態では、かご受け構造体９の敷居側端部が形成されているリンク部材が第１リンク部材９１となっている。また、本実施の形態では、かご受け構造体９の反敷居側端部が形成されているリンク部材が第２リンク部材９２となっている。 One end of the car support structure 9 is the threshold-side end. The other end of the car support structure 9 is an end opposite to the threshold. The position of the sill-side end of the car receiving structure 9 is closer to the landing threshold 23 than the position of the opposite-to-sill-side end of the car receiving structure 9 . The end of the car support structure 9 opposite to the threshold is attached to a support 10 . In the present embodiment, the first link member 91 is a link member formed with the threshold-side end of the car support structure 9 . Further, in the present embodiment, the second link member 92 is the link member on which the end of the car support structure 9 opposite to the sill is formed.
　かご受け構造体９の反敷居側端部は、支持軸１２によって傾斜板１０２に取り付けられている。支持軸１２は、傾斜板１０２に対して直交している。また、支持軸１２は、水平に配置されている。かご受け構造体９は、支持具１０に対して支持軸１２を中心に回転可能になっている。かご受け構造体９における各連結軸９３は、支持軸１２と平行である。 The end of the car support structure 9 opposite to the threshold is attached to the inclined plate 102 by the support shaft 12 . The support shaft 12 is perpendicular to the inclined plate 102 . Further, the support shaft 12 is arranged horizontally. The cage support structure 9 is rotatable around the support shaft 12 with respect to the support 10 . Each connecting shaft 93 in the cage support structure 9 is parallel to the support shaft 12 .
　かご受け構造体９の状態は、敷居到達状態と、退避状態との間で変化可能である。なお、図２及び図３では、かご受け構造体９の状態が敷居到達状態であるときの一対の作業補助装置８が示されている。 The state of the car support structure 9 can be changed between the threshold reached state and the retracted state. 2 and 3 show the pair of work assisting devices 8 when the car support structure 9 is in the threshold reached state.
　かご受け構造体９の状態が敷居到達状態であるときには、かご受け構造体９が支持具１０から乗場敷居２３に達している。具体的には、かご受け構造体９の状態が敷居到達状態であるとき、昇降路１の幅方向においてかご受け構造体９の反敷居側端部の位置よりも昇降路１の中央に近い位置でかご受け構造体９の敷居側端部が最下階の乗場敷居２３に達している。これにより、かご受け構造体９の状態が敷居到達状態であるときには、昇降路１を上から見ると、昇降路１の幅方向及び昇降路１の奥行き方向のいずれに対してもかご受け構造体９が傾斜している。また、昇降路１を上から見たとき、作業補助装置８では、図３に示すように、かご受け構造体９の状態が敷居到達状態になることにより、かご受け構造体９の一部がかご２の領域に重なる。 When the state of the car receiving structure 9 is the threshold reached state, the car receiving structure 9 has reached the landing threshold 23 from the support 10 . Specifically, when the car support structure 9 is in the threshold reached state, the position is closer to the center of the hoistway 1 than the position of the end of the car support structure 9 opposite to the threshold in the width direction of the hoistway 1. The sill-side end of the car support structure 9 reaches the landing sill 23 on the lowest floor. As a result, when the car support structure 9 is in the threshold reaching state, the car support structure 9 is positioned in both the width direction of the hoistway 1 and the depth direction of the hoistway 1 when the hoistway 1 is viewed from above. 9 is slanted. When the hoistway 1 is viewed from above, as shown in FIG. Overlaps the area of car 2.
　かご受け構造体９の状態が退避状態であるときには、かご受け構造体９が乗場敷居２３から外れている。昇降路１を上から見たとき、作業補助装置８では、かご受け構造体９の状態が退避状態になることにより、かご受け構造体９がかご２の領域から外れる。 When the car support structure 9 is in the retracted state, the car support structure 9 is off the landing threshold 23 . When the hoistway 1 is viewed from above, the car support structure 9 moves out of the region of the car 2 in the work assisting device 8 by moving the car support structure 9 to the retracted state.
　図４は、図２の作業補助装置８を示す拡大図である。図５は、図４のかご受け構造体９の状態が退避状態であるときの作業補助装置８を示す拡大図である。かご受け構造体９の状態は、図４に示すように、かご受け構造体９が伸びることにより敷居到達状態になる。また、かご受け構造体９の状態は、図５に示すように、かご受け構造体９が縮むことにより退避状態になる。 FIG. 4 is an enlarged view showing the work assisting device 8 of FIG. FIG. 5 is an enlarged view showing the work assisting device 8 when the car support structure 9 in FIG. 4 is in the retracted state. As shown in FIG. 4, the car support structure 9 reaches the threshold by extending the car support structure 9 . Further, as shown in FIG. 5, the cage receiving structure 9 is in a retracted state by contracting the cage receiving structure 9 .
　ここで、互いに隣り合う２つのリンク部材である第１リンク部材９１及び第２リンク部材９２を互いに連結する連結軸９３から第１リンク部材９１及び第２リンク部材９２のそれぞれの長手方向に沿って延びる２つの直線がなす角度をリンク間角度とする。このとき、かご受け構造体９は、リンク間角度が１８０°に近づく方向へ第１リンク部材９１及び第２リンク部材９２同士が回転することにより展開される。かご受け構造体９が展開されると、図４に示すように、複数の第１リンク部材９１及び複数の第２リンク部材９２が同一直線上に並んでかご受け構造体９が伸びる。 Here, along the longitudinal direction of each of the first link member 91 and the second link member 92 from the connecting shaft 93 that connects the first link member 91 and the second link member 92, which are two link members adjacent to each other, An angle formed by two extending straight lines is defined as an angle between links. At this time, the cage support structure 9 is deployed by rotating the first link member 91 and the second link member 92 in a direction in which the angle between the links approaches 180°. When the car receiving structure 9 is deployed, as shown in FIG. 4, the plurality of first link members 91 and the plurality of second link members 92 are aligned on the same straight line and the car receiving structure 9 extends.
　かご受け構造体９は、リンク間角度が小さくなる方向へ第１リンク部材９１及び第２リンク部材９２同士が回転することにより折り畳まれる。かご受け構造体９が折り畳まれると、図５に示すように、第１リンク部材９１と第２リンク部材９２との連結部分が折れ曲がってかご受け構造体９が縮む。 The car support structure 9 is folded by rotating the first link member 91 and the second link member 92 in the direction in which the angle between the links becomes smaller. When the car support structure 9 is folded, as shown in FIG. 5, the connecting portion between the first link member 91 and the second link member 92 is bent and the car support structure 9 is contracted.
　かご受け構造体９の敷居側端部が形成された第１リンク部材９１には、突起９４が設けられている。突起９４は、第１リンク部材９１の長手方向及びかご受け構造体９の幅方向のいずれにも直交する方向へ第１リンク部材９１から突出している。かご受け構造体９の状態が敷居到達状態であるときには、突起９４が第１リンク部材９１から下方へ突出している。また、かご受け構造体９の状態が敷居到達状態であるときには、最下階の乗場敷居２３における敷居溝２４に突起９４が嵌る。これにより、かご受け構造体９は、乗場敷居２３に固定される。 A projection 94 is provided on the first link member 91 on which the threshold-side end of the car support structure 9 is formed. The protrusion 94 protrudes from the first link member 91 in a direction orthogonal to both the longitudinal direction of the first link member 91 and the width direction of the car receiving structure 9 . When the cage receiving structure 9 is in the threshold reached state, the projection 94 projects downward from the first link member 91 . Further, when the car receiving structure 9 is in the threshold reached state, the projection 94 fits into the threshold groove 24 in the landing threshold 23 of the lowest floor. Thereby, the car receiving structure 9 is fixed to the landing threshold 23 .
　索状体１１は、かご受け構造体９に接続されている。本実施の形態では、かご受け構造体９の敷居側端部が形成された第１リンク部材９１に索状体１１が接続されている。また、索状体１１は、最下階の乗場敷居２３にも接続されている。索状体１１は、かご受け構造体９から乗場敷居２３にわたって垂れ下がっている。一対の作業補助装置８のそれぞれでは、かご受け構造体９の状態が退避状態になっているときにかご２が最下階に停止しても、かご２が索状体１１に干渉しない十分な長さに索状体１１の長さが確保されている。索状体１１としては、ワイヤ、ロープ、チェーンなどが用いられている。 The cord-like body 11 is connected to the car receiving structure 9 . In the present embodiment, the cord-like body 11 is connected to the first link member 91 formed with the threshold-side end of the car support structure 9 . The cord-like body 11 is also connected to a landing threshold 23 on the lowest floor. The cord-like body 11 hangs from the car receiving structure 9 over the landing threshold 23 . In each of the pair of work assisting devices 8, even if the car 2 stops at the lowest floor when the car receiving structure 9 is in the retracted state, the car 2 does not interfere with the cord-like body 11. The length of the cord-like body 11 is ensured. A wire, a rope, a chain, or the like is used as the cord-like body 11 .
　次に、一対の作業補助装置８の取り扱い方法について説明する。一対のかごガイドレール６には、作業補助装置８がそれぞれ予め取り付けられている。エレベータの通常運転時には、一対の作業補助装置８のそれぞれにおいてかご受け構造体９の状態が退避状態となっている。この状態では、かご２及び釣合おもり３が昇降路１内を移動しても、かご２及び釣合おもり３に各作業補助装置８が干渉することはない。 Next, how to handle the pair of work assisting devices 8 will be described. A work assisting device 8 is attached in advance to each of the pair of car guide rails 6 . During normal operation of the elevator, the car support structure 9 of each of the pair of work assisting devices 8 is in the retracted state. In this state, even if the car 2 and the counterweight 3 move in the hoistway 1 , the work assisting devices 8 do not interfere with the car 2 and the counterweight 3 .
　昇降路１の底部に設置されているエレベータ機器に対する保守作業を行うときには、作業者が最下階の乗場出入口２１を開く。また、作業者は、最下階よりも上方へかご２を移動させる。これにより、最下階の乗場にいる作業者は、乗場敷居２３に接続されている各索状体１１を引くことができる。この後、作業者は、各作業補助装置８において、索状体１１を引きながら、かご受け構造体９の敷居側端部を乗場敷居２３に近づける。これにより、かご受け構造体９が伸びて、かご受け構造体９の敷居側端部が乗場敷居２３に達する。このようにして、各作業補助装置８では、かご受け構造体９の状態が敷居到達状態になる。 When performing maintenance work on the elevator equipment installed at the bottom of the hoistway 1, the worker opens the landing doorway 21 on the lowest floor. Also, the operator moves the car 2 above the lowest floor. As a result, a worker at the landing on the lowest floor can pull each cord-like body 11 connected to the landing threshold 23 . After that, the operator brings the sill-side end of the car support structure 9 closer to the landing sill 23 while pulling the cord-like body 11 on each work auxiliary device 8 . As a result, the car receiving structure 9 extends and the sill-side end of the car receiving structure 9 reaches the landing sill 23 . In this manner, in each work assisting device 8, the state of the cage receiving structure 9 becomes the state of reaching the threshold.
　この後、作業者は、各作業補助装置８において、かご受け構造体９の突起９４を乗場敷居２３の敷居溝２４に嵌める。これにより、各かご受け構造体９が乗場敷居２３に固定される。かご受け構造体９の状態が敷居到達状態であるときには、かご２が最下階よりも下方へ移動しようとすると、かご２がかご受け構造体９と干渉し、昇降路１の底部へのかご２の侵入が阻止される。これにより、昇降路１の底部における作業者の作業空間が確保される。 After that, the worker fits the protrusion 94 of the car support structure 9 into the threshold groove 24 of the landing threshold 23 of each work auxiliary device 8 . Thereby, each car receiving structure 9 is fixed to the landing threshold 23 . When the car receiving structure 9 is in the threshold reached state, when the car 2 tries to move below the lowest floor, the car 2 interferes with the car receiving structure 9 and the car moves to the bottom of the hoistway 1. 2 is blocked. As a result, a work space for the worker at the bottom of the hoistway 1 is ensured.
　この後、作業者は、最下階の乗場出入口２１から昇降路１の底部に入り、エレベータ機器に対して保守作業を行う。 After that, the worker enters the bottom of the hoistway 1 from the landing doorway 21 on the lowest floor and performs maintenance work on the elevator equipment.
　エレベータ機器に対する保守作業の終了後、作業者は、昇降路１の底部から最下階の乗場出入口２１を通って最下階の乗場に移動する。この後、作業者は、各作業補助装置８の突起９４を乗場敷居２３の敷居溝２４から外し、各かご受け構造体９の敷居側端部を棒などの道具によって支持具１０に向けて押す。これにより、各作業補助装置８では、かご受け構造体９が縮み、かご受け構造体９の状態が退避状態になる。この後、作業者は、最下階の乗場出入口２１を閉じる。これにより、エレベータ機器に対する保守作業が終了する。 After the maintenance work on the elevator equipment is completed, the worker moves from the bottom of the hoistway 1 to the landing on the lowest floor through the landing doorway 21 on the lowest floor. After that, the operator removes the projections 94 of each work auxiliary device 8 from the threshold groove 24 of the landing threshold 23, and pushes the threshold-side end of each car receiving structure 9 toward the support 10 with a tool such as a rod. . As a result, in each work assisting device 8, the car support structure 9 contracts, and the state of the car support structure 9 becomes the retracted state. After that, the worker closes the landing doorway 21 on the lowest floor. This completes the maintenance work on the elevator equipment.
　このような作業補助装置８では、かご受け構造体９に接続された索状体１１が乗場敷居２３に接続されている。また、かご受け構造体９の状態が敷居到達状態と退避状態との間で変化可能になっている。このため、作業者が乗場から索状体１１を引くことにより、かご受け構造体９の状態を退避状態から敷居到達状態に変化させることができる。これにより、昇降路１の底部へのかご２の侵入をかご受け構造体９によって阻止することができる。従って、作業者が昇降路１の底部に入らずに昇降路１の底部における作業者の作業空間を確保することができる。このようなことから、作業者の作業空間を確保する作業を作業者が昇降路１の底部に入って行う必要がなくなり、昇降路１の底部における作業者の作業負担の軽減を図ることができる。 In such a work assisting device 8 , the cord-like body 11 connected to the car support structure 9 is connected to the landing threshold 23 . Further, the state of the car support structure 9 can be changed between the threshold reached state and the retracted state. Therefore, the state of the car receiving structure 9 can be changed from the retracted state to the threshold reached state by the operator pulling the cord-like body 11 from the landing. Thus, the car 2 can be prevented from entering the bottom of the hoistway 1 by the car receiving structure 9 . Therefore, a working space for the worker at the bottom of the hoistway 1 can be secured without the worker entering the bottom of the hoistway 1 . As a result, there is no need for the worker to enter the bottom of the hoistway 1 to secure a work space for the worker, and the work burden on the worker at the bottom of the hoistway 1 can be reduced. .
　また、かご受け構造体９の状態は、かご受け構造体９が伸びることにより敷居到達状態になり、かご受け構造体９が縮むことにより退避状態になる。このため、退避状態になっているときのかご受け構造体９の配置スペースの縮小化を図ることができる。これにより、昇降路１内のスペースを有効に活用することができる。 Further, the state of the car support structure 9 is changed to the threshold reached state by extension of the car support structure 9, and to the retracted state by contraction of the car support structure 9. Therefore, it is possible to reduce the arrangement space of the car support structure 9 in the retracted state. Thereby, the space in the hoistway 1 can be effectively utilized.
　また、かご受け構造体９は、直列に連結された複数の第１リンク部材９１及び複数の第２リンク部材９２を有している。また、互いに隣り合う２つのリンク部材である第１リンク部材９１及び第２リンク部材９２が連結軸９３を中心に回転可能に連結されている。このため、第１リンク部材９１及び第２リンク部材９２同士の回転によってかご受け構造体９を伸縮させることができ、かご受け構造体９の構造を簡単にすることができる。 Further, the cage receiving structure 9 has a plurality of first link members 91 and a plurality of second link members 92 connected in series. A first link member 91 and a second link member 92, which are two link members adjacent to each other, are rotatably connected about a connecting shaft 93. As shown in FIG. Therefore, the car support structure 9 can be expanded and contracted by the rotation of the first link member 91 and the second link member 92, and the structure of the car support structure 9 can be simplified.

Each unit mechanism portion 951 generates a force in a direction to bring the first link member 91 and the second link member 92, which are two link members adjacent to each other, closer to each other. That is, the force of the unit mechanism portion 951 is applied to the first link member 91 and the second link member 92 adjacent to each other in the direction in which the cage receiving structure 9 is folded and contracted.
　各単位機構部９５１は、弾性体９５１ａと、第１接続部９５１ｂと、第２接続部９５１ｃとを有している。 Each unit mechanism portion 951 has an elastic body 951a, a first connection portion 951b, and a second connection portion 951c.

The second connecting portion 951 c is fixed to the second link member 92 . In the present embodiment, the first connecting portion 951b is fixed to the middle portion of the first link member 91 in the longitudinal direction, and the second connecting portion 951c is fixed to the middle portion of the second link member 92 in the longitudinal direction. there is Further, in the present embodiment, the first connecting portion 951b protrudes from the first link member 91 in a direction orthogonal to both the longitudinal direction of the first link member 91 and the direction along the connecting shaft 93 . Furthermore, in the present embodiment, the second connecting portion 951c is fixed in the space between the pair of link plates 921. As shown in FIG. A pin is used as each of the first connection portion 951b and the second connection portion 951c.
　弾性体９５１ａの一端部は、第１接続部９５１ｂに接続されている。弾性体９５１ａの他端部は、第２接続部９５１ｃに接続されている。弾性体９５１ａは、第１接続部９５１ｂと第２接続部９５１ｃとが互いに近づく方向へ弾性復元力を発生している。これにより、各単位機構部９５１は、第１リンク部材９１と第２リンク部材９２との間のリンク間角度が小さくなる方向へ弾性体９５１ａの弾性復元力を第１リンク部材９１及び第２リンク部材９２に加えている。本実施の形態では、弾性体９５１ａとしてばねが用いられている。 One end of the elastic body 951a is connected to the first connection portion 951b. The other end of the elastic body 951a is connected to the second connection portion 951c. The elastic body 951a generates an elastic restoring force in the direction in which the first connection portion 951b and the second connection portion 951c approach each other. As a result, each unit mechanism portion 951 applies the elastic restoring force of the elastic body 951a to the first link member 91 and the second link member 91 and the second link member 92 in the direction in which the inter-link angle between the first link member 91 and the second link member 92 becomes smaller. It is added to member 92 . In this embodiment, a spring is used as the elastic body 951a.
　エレベータの通常運転時には、一対の作業補助装置８のそれぞれにおいて、かご受け構造体９の状態が復元機構９５の力によって退避状態に保たれている。各作業補助装置８において、かご受け構造体９の状態を退避状態から敷居到達状態にするときには、乗場にいる作業者が索状体１１を引くことにより、復元機構９５の力に逆らって、かご受け構造体９が展開される。これにより、かご受け構造体９が伸びて、かご受け構造体９の敷居側端部が乗場敷居２３に達する。このようにして、かご受け構造体９の状態が敷居到達状態になる。 During normal operation of the elevator, the car support structure 9 is kept in the retracted state by the force of the restoring mechanism 95 in each of the pair of work auxiliary devices 8 . In each work assisting device 8, when the state of the car receiving structure 9 is changed from the retracted state to the threshold reaching state, the operator at the landing pulls the cord-like body 11, thereby moving the car against the force of the restoring mechanism 95. A receiving structure 9 is deployed. As a result, the car receiving structure 9 extends and the sill-side end of the car receiving structure 9 reaches the landing sill 23 . In this way, the state of the cage support structure 9 becomes the threshold reaching state.
　各作業補助装置８において、かご受け構造体９の状態を敷居到達状態から退避状態に戻すとき、作業者は、かご受け構造体９の突起９４を乗場敷居２３の敷居溝２４から外すとともに、索状体１１を引く力を弱める。これにより、かご受け構造体９は、復元機構９５の力によって自動的に折り畳まれて縮む。このようにして、かご受け構造体９の状態が退避状態になる。本実施の形態における他の構成は、実施の形態１と同様である。 When returning the state of the car receiving structure 9 from the threshold reached state to the retracted state in each work auxiliary device 8, the operator removes the projection 94 of the car receiving structure 9 from the threshold groove 24 of the landing threshold 23 and The force that pulls the body 11 is weakened. Thereby, the cage receiving structure 9 is automatically folded and shrunk by the force of the restoring mechanism 95 . In this manner, the state of the cage support structure 9 is brought into the retracted state. Other configurations in this embodiment are the same as those in the first embodiment.
　このような作業補助装置８では、かご受け構造体９が縮む方向へ復元機構９５の力がかご受け構造体９に加わっている。このため、かご受け構造体９を支持具１０に向けて押さなくても、復元機構９５の力によってかご受け構造体９を縮めることができる。これにより、かご受け構造体９の状態を敷居到達状態から容易に退避状態にすることができる。 In such a work assisting device 8, the force of the restoring mechanism 95 is applied to the car support structure 9 in the direction in which the car support structure 9 contracts. Therefore, the car support structure 9 can be contracted by the force of the restoring mechanism 95 without pushing the car support structure 9 toward the support member 10 . As a result, the state of the car support structure 9 can be easily changed from the threshold reached state to the retracted state.

　このような作業補助装置８では、かご受け構造体９の状態が敷居到達状態であるときにかご受け構造体９が固定ボルト９６によって乗場敷居２３に固定される。このため、乗場敷居２３にかご受け構造体９をより確実に固定することができ、かご受け構造体９が乗場敷居２３から意図せず外れることをより確実に防止することができる。 In such a work assisting device 8, the car receiving structure 9 is fixed to the landing threshold 23 by the fixing bolts 96 when the car receiving structure 9 is in the threshold reaching state.

　かご受け構造体９の敷居側端部が形成された第１リンク部材９１には、貫通孔９１２が設けられている。貫通孔９１２は、第１リンク部材９１の長手方向及びかご受け構造体９の幅方向のいずれにも直交する方向へ第１リンク部材９１を貫通している。 A through hole 912 is provided in the first link member 91 formed with the threshold-side end of the car support structure 9 .

　ボルト９７１のねじ部は、貫通孔９１２に通されている。また、ボルト９７１のねじ部は、ねじ穴９７３に取り付けられている。貫通孔９１２に通されたボルト９７１のねじ部がねじ穴９７３に締め込まれることにより、第１リンク部材９１と押さえ部材９７２との間に乗場敷居２３が把持されている。これにより、かご受け構造体９は、乗場敷居２３に固定されている。即ち、かご受け構造体９と押さえ部材９７２との間に乗場敷居２３が把持されることにより、かご受け構造体９が乗場敷居２３に固定されている。かご受け構造体９が乗場敷居２３に固定されている状態では、突起９４が敷居溝２４に嵌っている。 The threaded portion of the bolt 971 is passed through the through hole 912 . Also, the threaded portion of the bolt 971 is attached to the threaded hole 973 . The landing threshold 23 is held between the first link member 91 and the pressing member 972 by screwing the threaded portion of the bolt 971 passed through the through hole 912 into the screw hole 973 .

　実施の形態５．
　図９は、実施の形態５による作業補助装置を示す上面図である。作業補助装置８は、取付部材１３を有している。取付部材１３は、支持具１０に取り付けられている。具体的には、取付部材１３が支持軸１２によって支持具１０の傾斜板１０２に取り付けられている。支持軸１２は、傾斜板１０２に対して直交している。また、支持軸１２は、水平に配置されている。取付部材１３は、支持具１０に対して支持軸１２を中心に回転可能になっている。 Embodiment 5.
FIG. 9 is a top view showing a work assisting device according to Embodiment 5. FIG. The work assistance device 8 has a mounting member 13 . The attachment member 13 is attached to the support 10 . Specifically, the attachment member 13 is attached to the inclined plate 102 of the support 10 by the support shaft 12 . The support shaft 12 is perpendicular to the inclined plate 102 . Further, the support shaft 12 is arranged horizontally. The mounting member 13 is rotatable around the support shaft 12 with respect to the support 10 .
　かご受け構造体９の反敷居側端部は、取付部材１３を介して傾斜板１０２に取り付けられている。かご受け構造体９の反敷居側端部は、取付軸１４によって取付部材１３に連結されている。取付軸１４は、各連結軸９３と平行な直線に直交する軸線を持つ軸である。取付軸１４は、支持軸１２に対して直交している。かご受け構造体９は、取付軸１４を中心に回転可能に取付部材１３に連結されている。本実施の形態では、かご受け構造体９の反敷居側端部が形成されたリンク部材が第１リンク部材９１となっており、かご受け構造体９の敷居側端部が形成されたリンク部材も第１リンク部材９１となっている。また、本実施の形態では、かご受け構造体９の反敷居側端部が形成された第１リンク部材９１の長手方向に沿って取付軸１４が配置されている。 The end of the car support structure 9 opposite to the threshold is attached to the inclined plate 102 via the attachment member 13 . An end of the car support structure 9 opposite to the threshold is connected to a mounting member 13 by a mounting shaft 14 . The mounting shaft 14 is a shaft having an axis orthogonal to a straight line parallel to each connecting shaft 93 . The mounting shaft 14 is perpendicular to the support shaft 12 . The cage receiving structure 9 is connected to the mounting member 13 so as to be rotatable about the mounting shaft 14 . In the present embodiment, the link member on which the opposite-sill side end of the car support structure 9 is formed is the first link member 91, and the link member on which the threshold-side end of the car support structure 9 is formed. is also the first link member 91 . Further, in the present embodiment, the mounting shaft 14 is arranged along the longitudinal direction of the first link member 91 on which the end of the car support structure 9 opposite to the threshold is formed.
　突起９４は、かご受け構造体９の敷居側端部が形成された第１リンク部材９１から各連結軸９３と平行な方向へ突出している。これにより、かご受け構造体９が取付軸１４を中心に回転して突起９４が水平になると、かご受け構造体９の各連結軸９３も水平になる。また、かご受け構造体９が取付軸１４を中心に回転して突起９４が下方を向くと、かご受け構造体９の各連結軸９３が鉛直方向に沿って配置される。 The protrusions 94 protrude in a direction parallel to the connecting shafts 93 from the first link member 91 formed with the sill-side end of the car support structure 9 . As a result, when the car support structure 9 rotates about the mounting shaft 14 and the protrusions 94 become horizontal, the connecting shafts 93 of the car support structure 9 also become horizontal. Further, when the car support structure 9 rotates around the mounting shaft 14 and the protrusions 94 face downward, the connecting shafts 93 of the car support structure 9 are arranged along the vertical direction.
　図１０は、図９のかご受け構造体９の突起９４が乗場敷居２３の敷居溝２４に嵌っている状態を示す上面図である。かご受け構造体９の状態が敷居到達状態であるときにかご受け構造体９の突起９４が乗場敷居２３の敷居溝２４に嵌ると、突起９４が下方を向く。これにより、かご受け構造体９の各連結軸９３が鉛直方向に沿って配置される。 FIG. 10 is a top view showing a state where the protrusion 94 of the car support structure 9 of FIG. 9 is fitted into the threshold groove 24 of the landing threshold 23. FIG. When the projection 94 of the car receiving structure 9 fits into the threshold groove 24 of the landing threshold 23 when the car receiving structure 9 is in the threshold reached state, the projection 94 faces downward. As a result, each connecting shaft 93 of the cage support structure 9 is arranged along the vertical direction.
　各作業補助装置８において、かご受け構造体９の状態を退避状態から敷居到達状態にするときには、乗場にいる作業者が索状体１１を引くことにより、かご受け構造体９が展開される。このとき、各連結軸９３が水平に配置されている状態でかご受け構造体９が展開される。これにより、かご受け構造体９が伸びて、かご受け構造体９の敷居側端部が乗場敷居２３に達する。このようにして、かご受け構造体９の状態が敷居到達状態になる。 In each work assisting device 8, when the state of the car support structure 9 is changed from the retracted state to the threshold reached state, the car support structure 9 is deployed by the operator at the landing pulling the cord-like body 11.例文帳に追加At this time, the car support structure 9 is deployed with the connecting shafts 93 arranged horizontally. As a result, the car receiving structure 9 extends and the sill-side end of the car receiving structure 9 reaches the landing sill 23 . In this way, the state of the cage support structure 9 becomes the threshold reached state.
　この後、作業者は、突起９４が下方を向くまで、かご受け構造体９を取付部材１３に対して取付軸１４を中心に回転させる。これにより、図１０に示すように、各連結軸９３が鉛直方向に沿って配置される。この後、突起９４を敷居溝２４に嵌める。これにより、かご受け構造体９が乗場敷居２３に固定される。 After that, the operator rotates the car support structure 9 around the mounting shaft 14 with respect to the mounting member 13 until the protrusion 94 faces downward. Thereby, as shown in FIG. 10, each connecting shaft 93 is arranged along the vertical direction. After that, the projection 94 is fitted into the threshold groove 24 . Thereby, the car receiving structure 9 is fixed to the landing threshold 23 .
　各作業補助装置８において、かご受け構造体９の状態を敷居到達状態から退避状態に戻すとき、作業者は、突起９４を敷居溝２４から外すとともに、突起９４が水平になるまで、かご受け構造体９を取付部材１３に対して取付軸１４を中心に回転させる。この後、作業者は、かご受け構造体９を支持具１０に向けて押す。これにより、かご受け構造体９が折り畳まれて縮む。このようにして、かご受け構造体９の状態が退避状態になる。本実施の形態における他の構成は、実施の形態１と同様である。 In each work auxiliary device 8, when returning the state of the car support structure 9 from the threshold reached state to the retracted state, the operator removes the projection 94 from the threshold groove 24 and moves the car support structure until the projection 94 becomes horizontal. The body 9 is rotated about the mounting shaft 14 with respect to the mounting member 13 . After that, the operator pushes the cage support structure 9 toward the support 10 . As a result, the cage receiving structure 9 is folded and shrunk. In this manner, the state of the cage support structure 9 is brought into the retracted state. Other configurations in this embodiment are the same as those in the first embodiment.
　このような作業補助装置８では、各連結軸９３と平行な直線に直交する軸線を持つ取付軸１４を中心に回転可能にかご受け構造体９が取付部材１３に連結されている。このため、かご受け構造体９の状態が敷居到達状態であるときに各連結軸９３を鉛直方向に沿って配置することができる。これにより、鉛直方向に沿った荷重に対するかご受け構造体９の剛性を高めることができる。従って、例えばかご受け構造体９がかご２の荷重を上方から鉛直方向下向きに受けた場合であっても、かご受け構造体９を曲がりにくくすることができ、昇降路１の底部における作業者の作業空間をより確実に確保することができる。 In such a work assisting device 8 , the car support structure 9 is connected to the mounting member 13 so as to be rotatable about the mounting shaft 14 having an axis perpendicular to the straight line parallel to each connecting shaft 93 . Therefore, each connecting shaft 93 can be arranged in the vertical direction when the cage support structure 9 is in the threshold reaching state. Thereby, the rigidity of the car support structure 9 against the load along the vertical direction can be increased. Therefore, for example, even when the car support structure 9 receives the load of the car 2 downward in the vertical direction from above, the car support structure 9 can be made difficult to bend. A work space can be secured more reliably.

　抜け止め部材９９は、かご受け構造体９の反敷居側端部に固定されている。また、抜け止め部材９９は、一対の長尺板９８１の間に固定されている。本実施の形態では、一対の長尺板９８１を互いに繋ぐピンが抜け止め部材９９として用いられている。抜け止め部材９９は、かご受け構造体９の幅方向に沿って配置されている。 The retaining member 99 is fixed to the end of the car support structure 9 opposite to the threshold. Also, the retaining member 99 is fixed between a pair of long plates 981 . In this embodiment, a pin that connects the pair of long plates 981 to each other is used as the retaining member 99 . The retaining member 99 is arranged along the width direction of the car receiving structure 9 .
　かご受け構造体９の敷居側端部には、突起９４が設けられている。突起９４は、延長部材１００から下方へかご受け構造体９の厚さ方向に沿って突出している。最下階の乗場敷居２３に接続された索状体１１は、図１１に示すように、延長部材１００に接続されている。 A protrusion 94 is provided at the threshold-side end of the car support structure 9 . The protrusion 94 protrudes downward from the extension member 100 along the thickness direction of the car receiving structure 9 . The cord-like body 11 connected to the landing threshold 23 on the lowest floor is connected to an extension member 100 as shown in FIG.
　かご受け構造体９の一部は、一対の対向板１０５の間の空間に通されている。これにより、かご受け構造体９は、かご受け構造体９の厚さ方向において一対の対向板１０５の間に挟まれている。かご受け構造体９は、一対の対向板１０５のそれぞれに案内されながら、一対の対向板１０５に沿った方向、即ち水平方向へ支持具１０に対して移動可能になっている。 A part of the car support structure 9 is passed through the space between the pair of opposing plates 105 . Thus, the car support structure 9 is sandwiched between the pair of opposing plates 105 in the thickness direction of the car support structure 9 . The cage receiving structure 9 is movable relative to the support 10 in a direction along the pair of opposing plates 105, that is, in a horizontal direction while being guided by the pair of opposing plates 105 respectively.
　固定ピン１０７は、一対の長尺板９８１の間に通されている。また、固定ピン１０７は、本体部材９８の長手方向へ一対の長尺板９８１の間をスライド可能になっている。これにより、かご受け構造体９は、かご受け構造体９の軸線に沿った方向へ固定ピン１０７に対してスライドされながら、支持具１０に対して移動可能になっている。かご受け構造体９が固定ピン１０７に対してスライド可能な範囲は、抜け止め部材９９と延長部材１００との間の範囲である。また、かご受け構造体９は、固定ピン１０７を中心として支持具１０に対して回転可能にもなっている。 The fixing pin 107 is passed between the pair of long plates 981 . Also, the fixing pin 107 is slidable between the pair of long plates 981 in the longitudinal direction of the main body member 98 . As a result, the car support structure 9 can move relative to the support 10 while being slid along the axis of the car support structure 9 with respect to the fixing pin 107 . The range in which the cage receiving structure 9 can slide with respect to the fixing pin 107 is the range between the retaining member 99 and the extension member 100 . Further, the cage receiving structure 9 is also rotatable with respect to the support 10 around the fixing pin 107 .
　各作業補助装置８では、支持具１０に対するかご受け構造体９の移動によって、かご受け構造体９の状態が敷居到達状態と退避状態との間で変化する。 In each work assisting device 8, the movement of the car receiving structure 9 relative to the support 10 changes the state of the car receiving structure 9 between the threshold reached state and the retracted state.
　かご受け構造体９の状態が敷居到達状態であるときには、本体部材９８が支持具１０に支持されているとともに、延長部材１００が乗場敷居２３に達している。また、かご受け構造体９の状態が敷居到達状態であるときには、乗場敷居２３の敷居溝２４に突起９４が嵌まる。 When the car support structure 9 is in the threshold reached state, the main body member 98 is supported by the support 10 and the extension member 100 reaches the landing threshold 23 . Further, when the car receiving structure 9 is in the threshold reached state, the projection 94 is fitted into the threshold groove 24 of the landing threshold 23 .
　図１３は、図１２のかご受け構造体９の状態が退避状態であるときの各作業補助装置８を示す断面図である。かご受け構造体９の状態が退避状態であるときには、かごガイドレール６の背面と昇降路１の内壁面との間の空間にかご受け構造体９が配置されている。また、かご受け構造体９の状態が退避状態であるときには、本体部材９８の一部が一対の対向板１０５の間の空間に収まっているとともに、かご受け構造体９が昇降路１の奥行き方向に沿って配置されている。さらに、かご受け構造体９の状態が退避状態であるときには、乗場敷居２３に対して支持具１０よりも遠い側へ本体部材９８の一部が支持具１０から突出している。 FIG. 13 is a sectional view showing each work assisting device 8 when the car support structure 9 in FIG. 12 is in the retracted state. When the car support structure 9 is in the retracted state, the car support structure 9 is arranged in the space between the rear surface of the car guide rail 6 and the inner wall surface of the hoistway 1 . Further, when the car support structure 9 is in the retracted state, part of the main body member 98 is accommodated in the space between the pair of opposing plates 105, and the car support structure 9 extends in the depth direction of the hoistway 1. are placed along the Furthermore, when the car receiving structure 9 is in the retracted state, a part of the main body member 98 protrudes from the support 10 farther than the support 10 with respect to the landing threshold 23 .
　かご受け構造体９の状態を退避状態から敷居到達状態にするときには、索状体１１を乗場から引くことにより、乗場敷居２３に近づく方向へかご受け構造体９を支持具１０に対して移動させる。このとき、かご受け構造体９は、固定ピン１０７を中心として支持具１０に対して回転しながら、抜け止め部材９９が固定ピン１０７に近づく方向へ支持具１０に対して移動する。これにより、かご受け構造体９の延長部材１００が乗場敷居２３に達する。このようにして、かご受け構造体９の状態が敷居到達状態となる。この後、延長部材１００の突起９４を敷居溝２４に嵌める。 When changing the state of the car receiving structure 9 from the retracted state to the threshold reaching state, the car receiving structure 9 is moved with respect to the support 10 in a direction approaching the landing threshold 23 by pulling the cord-like body 11 from the landing. . At this time, the cage receiving structure 9 rotates about the fixing pin 107 with respect to the support 10 , and the retaining member 99 moves with respect to the support 10 in a direction toward the fixing pin 107 . Thereby, the extension member 100 of the car receiving structure 9 reaches the landing threshold 23 . In this manner, the state of the cage receiving structure 9 becomes the threshold reaching state. After that, the protrusion 94 of the extension member 100 is fitted into the threshold groove 24 .
　また、かご受け構造体９の状態を敷居到達状態から退避状態にするときには、突起９４を敷居溝２４から外した後、棒などの道具を用いて、乗場敷居２３から遠ざかる方向へかご受け構造体９を押す。これにより、かご受け構造体９は、かごガイドレール６の背面と昇降路１の内壁面との間の空間に向けて支持具１０に対して移動する。このとき、かご受け構造体９は、固定ピン１０７を中心として支持具１０に対して回転しながら、延長部材１００が固定ピン１０７に近づく方向へ支持具１０に対して移動する。これにより、乗場敷居２３に対して支持具１０よりも遠い側へ本体部材９８の一部が支持具１０から突出するとともに、本体部材９８の一部が一対の対向板１０５の間の空間に収まる。これにより、かご受け構造体９の状態が退避状態となる。本実施の形態における他の構成は、実施の形態１と同様である。 Further, when changing the state of the car support structure 9 from the sill reached state to the retracted state, after removing the projection 94 from the sill groove 24, the car support structure 9 is moved away from the landing sill 23 using a tool such as a stick. Press 9. As a result, the car receiving structure 9 moves relative to the support 10 toward the space between the rear surface of the car guide rail 6 and the inner wall surface of the hoistway 1 . At this time, the car receiving structure 9 rotates about the fixing pin 107 with respect to the support 10 , while the extension member 100 moves with respect to the support 10 in a direction toward the fixing pin 107 . As a result, part of the body member 98 protrudes from the support 10 farther than the support 10 with respect to the landing threshold 23, and part of the body member 98 is accommodated in the space between the pair of opposing plates 105. . As a result, the state of the cage support structure 9 becomes the retracted state. Other configurations in this embodiment are the same as those in the first embodiment.
