A support beam 4 connected to the lower end of the vertical pillar 3, and a horizontal beam 5 connected to the upper side of the vertical pillar 3 and elongated in the depth direction (horizontal direction in FIG. 1) of the car 1 perpendicular to the opening/closing direction of the door 2. It has
　更に、乗りかご１の天井面１ａには、乗りかご１内の空気を換気するためのファンやイオン発生器、作業員が乗りかご１内と会話するために必要な乗りかご上機器１３が配置されている。 Furthermore, on the ceiling surface 1a of the car 1, a fan and an ion generator for ventilating the air in the car 1, and equipment 13 on the car necessary for a worker to communicate with the inside of the car 1 are arranged. It is
　また、横梁５の上方においては、この横梁５に取り付けられた複数の支持材８と、支持材８とは別に横梁５に取り付けられた手摺１２と、この手摺１２を乗りかご１の奥行方向（図１の左右方向）に対して手前側と奥側で支持する第１の手摺用支柱１１ａと、乗りかご１の中間で支持する第２の手摺用支柱１１ｂと、乗りかご１の天井にある横梁５の上面に設置され、乗りかご１を支持する上枠である構造物６とを有している。 Above the cross beams 5, a plurality of support members 8 attached to the cross beams 5, handrails 12 attached to the cross beams 5 separately from the support members 8, and the handrails 12 extending in the depth direction of the car 1 ( 1), a second handrail support 11b supported in the middle of the car 1, and a handrail support 11b supported in the middle of the car 1. It has a structure 6 which is installed on the upper surface of the cross beam 5 and which is an upper frame for supporting the car 1 .
　そして、本実施例では、手摺１２に取付けられている平板状の鋼板７が構造物６より上方（乗りかご１の天井部）、具体的には、鋼板７が乗りかご上機器１３より上部に、乗りかご上機器１３を覆うように配置されている。 In this embodiment, the flat steel plate 7 attached to the handrail 12 is positioned above the structure 6 (the ceiling of the car 1), specifically, above the equipment 13 on the car. , are arranged to cover the equipment 13 on the car.
　また、上記した平板状の鋼板７は、支持材８に接続されたヒンジ９を介して回動可能に支持され、かつ、第１の手摺用支柱１１ａ及び第２の手摺用支柱１１ｂの側面にある長穴１４ａ、１４ｂ（図４（ａ）及び図４（ｂ）参照）に通されたボルト及びナットで構成されている締結具１０ａ、１０ｂによって脱着可能に係合されている。 The flat steel plate 7 is rotatably supported via a hinge 9 connected to a support member 8, and is attached to the side surfaces of the first handrail support 11a and the second handrail support 11b. They are detachably engaged by fasteners 10a, 10b consisting of bolts and nuts passed through certain slots 14a, 14b (see FIGS. 4(a) and 4(b)).
　このような構成より、エレベーター装置の通常運転時（図１の状態）においては、乗りかご１の上に保守作業員を乗せて高速運転することはないため、手摺１２に鋼板７を格納している状態（図３の垂直に立てられた鋼板７´の位置の状態）にあるが、鋼板７が、構造物６の上部に乗りかご１の上面の投影面を覆うように配置した状態としても特に影響はない。つまり、保守作業員１人分の退避スペースが設けられる乗りかご１のサイズであれば、鋼板７を構造物６の上部に設置する必要はない。 With such a configuration, the steel plate 7 is housed in the handrail 12 because maintenance workers are not placed on the car 1 during normal operation of the elevator system (the state shown in FIG. 1). 3), the steel plate 7 can be placed above the structure 6 so as to cover the projected plane of the upper surface of the car 1. No particular impact. In other words, if the size of the car 1 is such that the evacuation space for one maintenance worker is provided, there is no need to install the steel plate 7 on the upper part of the structure 6 .
　図２は、図１で説明した内容に対して、乗りかご１の頂部に設置されている機器（例えば巻上機）の保守を行う際に、乗りかご１の上に保守作業員が乗り保守作業を行う状態、即ち、保守作業員の退避スペースが必要な場合を考慮している。 FIG. 2 shows a maintenance worker riding on top of the car 1 when performing maintenance of equipment (for example, a hoist) installed on the top of the car 1, in contrast to the contents described in FIG. Consideration is given to the situation in which work is being performed, that is, the case where a space for evacuation of maintenance workers is required.
　本実施例では、２人分の保守作業員の退避スペースを確保するために、鋼板７が構造物６の上部も含めて乗りかご１の上面の投影面を覆うように水平に配置されており、鋼板７の上が保守作業員の足場となり、退避できるスペースが生まれる。 In this embodiment, in order to secure an evacuation space for two maintenance workers, the steel plate 7 is arranged horizontally so as to cover the projected plane of the upper surface of the car 1 including the upper part of the structure 6. , the top of the steel plate 7 serves as a foothold for the maintenance worker, creating a space for evacuation.
　図３は、図２のＡ－Ａ線に沿った断面図であるが、本実施例のエレベーター装置の通常運転時（図１参照）から乗りかご１上に保守作業員が乗っている場合の退避時及び保守運転時（図２参照）へ、乗りかご１の上部の鋼板７の形態（格納（垂直配置）から展開（水平配置））を変える動作を示す図である（図３の左右の矢印は、水平配置の鋼板７を垂直配置に格納する際の動作を示す）。 FIG. 3 is a cross-sectional view taken along the line AA in FIG. 2, showing a state in which a maintenance worker is on the car 1 during normal operation of the elevator system of this embodiment (see FIG. 1). Fig. 3 is a diagram showing the operation of changing the form (from storage (vertical arrangement) to deployment (horizontal arrangement)) of the steel plate 7 on the upper part of the car 1 (left and right in Fig. 3) during evacuation and maintenance operation (see Fig. 2). The arrows indicate the action of retracting the horizontally arranged steel plate 7 into the vertical arrangement).
　次に、図１、図２、図３、図４（ａ）、図４（ｂ）及び図５を用いて、本実施例のエレベーター装置の乗りかご１の形態を、通常運転時（図１参照）から乗りかご１の上に保守作業員がいた場合の退避時及び保守運転時(図２)に変える際の動作について説明する。 Next, referring to FIGS. 1, 2, 3, 4(a), 4(b) and 5, the configuration of the car 1 of the elevator system of this embodiment will be described during normal operation (see FIG. 1). ) to the time of evacuation and the time of maintenance operation (FIG. 2) when a maintenance worker is on top of the car 1 will be described.
　図４（ａ）は図１のＢ部の詳細を示し、図４（ｂ）は図１のＣ部の詳細を示すが、図１に示す鋼板７と第１の手摺用支柱１１ａ及び第２の手摺用支柱１１ｂとの係合方法及び係合の解除動作を説明するものである。図５は、図３のＤ部の詳細を示すが、図３に示す鋼板７の開閉機構を説明するものである。 FIG. 4(a) shows the details of the B section of FIG. 1, and FIG. 4(b) shows the details of the C section of FIG. 2, a method of engaging with the handrail post 11b and an operation for releasing the engagement will be described. FIG. 5 shows the details of the D part of FIG. 3, and explains the opening and closing mechanism of the steel plate 7 shown in FIG.
　図５に示すように、支持材８に接続されたヒンジ９に対して、鋼板７は回動可能に支持され、かつ、ボルトとナットにより脱着可能であり、その回動端に三角形の一角を切断した形状を特徴とする補強用リブ１５を有し、また、支持材８には、補強用リブ１５の形状と印籠のようにして合わさる形状（同一形状）となっている切り欠き１６が形成されている。 As shown in FIG. 5, a steel plate 7 is rotatably supported by a hinge 9 connected to a support member 8, and is detachable by bolts and nuts. It has a reinforcing rib 15 characterized by a cut shape, and a notch 16 having a shape (same shape) that matches the shape of the reinforcing rib 15 like a coin box is formed in the support member 8. It is
　図４（ａ）及び図４（ｂ）に示すように、鋼板７は、第１の手摺用支柱１１ａ及び第２の手摺用支柱１１ｂに着脱可能で、かつ、自由自在に取り外しができる構造となっている。 As shown in FIGS. 4(a) and 4(b), the steel plate 7 is detachable from the first handrail post 11a and the second handrail post 11b, and can be freely removed. It's becoming
　具体的に説明すると、鋼板７の端部７ａは、第１の手摺用支柱１１ａ及び第２の手摺用支柱１１ｂに設けられた長穴１４ａ（図４（ａ）の左右方向に形成された長穴）及び１４ｂ（図４（ｂ）の上下方向に形成された長穴）の端部に通された締結具１０ａ及び１０ｂと、第１の手摺用支柱１１ａ及び第２の手摺用支柱１１ｂとの間に各々挟まれることにより係合されている。 More specifically, the end portion 7a of the steel plate 7 is formed in the elongated hole 14a (longitudinal direction in FIG. 4A) provided in the first handrail support 11a and the second handrail support 11b. fasteners 10a and 10b passed through the ends of holes) and 14b (long holes formed in the vertical direction in FIG. 4(b)), and a first handrail post 11a and a second handrail post 11b. are engaged by being sandwiched between them.
　即ち、締結具１０ａ及び１０ｂを、長穴１４ａ及び１４ｂの他方の円孔端部へ摺動（図４（ａ）では矢印で示す左右方向に摺動、図４（ｂ）では矢印で示す上下方向に摺動）させることにより、鋼板７は、第１の手摺用支柱１１ａ及び第２の手摺用支柱１１ｂとの係合が解除される。 That is, the fasteners 10a and 10b are slid to the other circular hole ends of the elongated holes 14a and 14b (in FIG. 4(a), they are slid in the left-right direction indicated by the arrows, and in FIG. The steel plate 7 is disengaged from the first handrail post 11a and the second handrail post 11b by sliding in the direction.
　一方で、鋼板７は、締結具１０ａ及び１０ｂを、各々前述した長穴１４ａ及び１４ｂの円孔端部の反対方向（図４（ａ）では左右方向、図４（ｂ）では上下方向）へ摺動させることにより、第１の手摺用支柱１１ａ及び第２の手摺用支柱１１ｂと係合される。 On the other hand, the steel plate 7 extends the fasteners 10a and 10b in the direction opposite to the circular hole ends of the long holes 14a and 14b described above (horizontal direction in FIG. 4(a), vertical direction in FIG. 4(b)). By sliding it, it engages with the first handrail post 11a and the second handrail post 11b.
　なお、第１の手摺用支柱１１ａに設けられた長穴１４ａは、乗りかご１の奥行方向と平行の方向に設けられなくてもよい。例えば、第１の手摺用支柱１１ａに設けられた長穴１４ａは、乗りかご１の上昇又は下降方向の向きに平行方向に設けてもよい。 The long hole 14a provided in the first handrail support 11a does not have to be provided in the direction parallel to the depth direction of the car 1. For example, the elongated holes 14a provided in the first handrail post 11a may be provided in a direction parallel to the ascending or descending direction of the car 1 .
　このとき、第１の手摺用支柱１１ａに設けられた長穴１４ａの向きは、第２の手摺用支柱１１ｂに設けられた長穴１４ｂと同方向であるため、締結具１０ａと締結具１０ｂとの係合方法と係合の解除動作に異なる点はない。 At this time, since the orientation of the elongated hole 14a provided in the first handrail support 11a is the same as the orientation of the elongated hole 14b provided in the second handrail support 11b, the fastener 10a and the fastener 10b are separated from each other. There is no difference between the engagement method and the disengagement operation.
　また、図５に示すように、支持材８に対して直動している鋼板７は、その回動端の一辺にヒンジ９の一対の羽根板９ａ１、９ａ２が取り付けられ、ヒンジ９の一方の羽根板９ａ２は、支持材８の上面に取り付けられている。 Further, as shown in FIG. 5, the steel plate 7 that moves linearly with respect to the support member 8 has a pair of blade plates 9a1 and 9a2 of the hinge 9 attached to one side of its rotating end. The blade plate 9 a 2 is attached to the upper surface of the support member 8 .
　また、鋼板７の回動端において、ドア２の開閉方向（左右方向）の内側で、かつ、長手方向の一辺に補強用リブ１５が設けられており、一方、支持材８には、ドア２の開閉方向の内側に、補強用リブ１５と同一形状の切り欠き１６が設けられている。 At the pivot end of the steel plate 7, a reinforcing rib 15 is provided inside the door 2 in the opening/closing direction (horizontal direction) and on one side in the longitudinal direction. A notch 16 having the same shape as the reinforcing rib 15 is provided inside in the opening/closing direction.
　即ち、前述した締結具１０ａ及び１０ｂとの係合の解除動作をした際、鋼板７は、図５に示すように、ヒンジ９により回動的に支持されており、鋼板７が回動することにより、図３に示すように、第１の手摺用支柱１１ａ及び第２の手摺用支柱１１ｂの側面と直交する向き（水平）に閉じられ、図２に示すように、乗りかご１の上面（平面）の投影面を覆うようになっている。 That is, when the engagement with the fasteners 10a and 10b described above is disengaged, the steel plate 7 is rotatably supported by the hinge 9 as shown in FIG. 3, the first handrail support pillar 11a and the second handrail support 11b are closed in a direction (horizontal) perpendicular to the side surfaces, and as shown in FIG. plane).
　このとき、鋼板７は、図３に示すように、上枠である構造物６の上面に配置され、また、図５に示すように、切り欠き１６と補強用リブ１５が同じ形状であるため、鋼板７の回動端にある補強用リブ１５は、支持材８にある切り欠き１６と合わさるように（重なるように）、出し入れ可能になっている。なお、図５の矢印は、補強用リブ１５を切り欠き１６に入れたり、出したりする動作を示す矢印である。 At this time, as shown in FIG. 3, the steel plate 7 is arranged on the upper surface of the structure 6 which is the upper frame, and as shown in FIG. , the reinforcing rib 15 at the rotating end of the steel plate 7 can be put in and taken out so as to match (overlap) the notch 16 in the support member 8 . In addition, the arrows in FIG. 5 indicate the operation of inserting the reinforcing rib 15 into the notch 16 and taking it out.
　以上の構成及び一連の動作によって、得られる作用を説明する。 The effect obtained by the above configuration and series of operations will be explained.
　図２に示すように、鋼板７は、乗りかご１の上面の投影図を覆うように水平に配置され、かつ、構造物６及び乗りかご上機器１３より上方に設けられているため、鋼板７は、乗りかご１の天井面１ａが、構造物６によって出入口からみて前面と背面側に２つに分断されていた平面を、鋼板７の上面の一平面に置き換えることができ、構造物６を配置することにより生じる凹凸の影響を、構造物６を鋼板７で覆うことで解消することができる。 As shown in FIG. 2, the steel plate 7 is arranged horizontally so as to cover the projection of the upper surface of the car 1 and is provided above the structure 6 and the equipment 13 on the car. , the ceiling surface 1a of the car 1 can be replaced by one plane on the upper surface of the steel plate 7, and the structure 6 can replace the plane where the ceiling surface 1a is divided into two by the structure 6 into the front side and the back side when viewed from the entrance. By covering the structure 6 with the steel plate 7, the influence of unevenness caused by the arrangement can be eliminated.
　また、図１に示すように、乗りかご１の天井面１ａに設置されている乗りかご上機器１３により、退避スペースが確保できなかったが、乗りかご上機器１３を鋼板７で覆うことで、鋼板７の上に退避スペースを確保することができる。 In addition, as shown in FIG. 1, it was not possible to secure a space for evacuation due to the car equipment 13 installed on the ceiling surface 1a of the car 1. However, by covering the car equipment 13 with a steel plate 7, A retreat space can be secured on the steel plate 7. - 特許庁
　以上の作用によって、実施例１のエレベーター装置は、保守作業員が２人以上いる場合の退避スペースを生み出すことができ、仮に乗りかご１のサイズ（間口×奥行）が小さい場合において、通常、保守作業員１人分の退避スペースしかない空間に対しても、２人分の退避スペースを備えることができる。 Due to the above action, the elevator apparatus of the first embodiment can create an evacuation space when there are two or more maintenance workers. It is possible to provide an evacuation space for two workers even in a space where there is only an evacuation space for one worker.
　一方で、特許文献１に記載の保守用足場は、空気調和機の箱体と連結された支持腕を有しているが、上記保守用足場は、箱体の１辺に対してのみ固定されているため、曲げモーメントが大きくかかりやすい。 On the other hand, the maintenance scaffold described in Patent Document 1 has support arms connected to the box of the air conditioner, but the maintenance scaffold is fixed only to one side of the box. Therefore, a large bending moment is likely to be applied.
　従って、保守作業員の体重と、意図しない乗りかご１の上昇運動による揺れとを勘定した場合、保守用足場の回動端を起点に破損する恐れがある。 Therefore, when considering the weight of the maintenance worker and the shaking caused by the unintended upward motion of the car 1, there is a risk of damage starting from the rotation end of the maintenance scaffold.
　これに対して、実施例１のエレベーター装置の構成は、図２に示すような閉じられた鋼板７の状態において、図３に示すように、その上面からの垂直荷重Ｆｗが負荷されたとき、この垂直荷重Ｆｗの分担は、図５に示すように、ヒンジ９で受け持つことなく、支持材８によって、分担荷重Ｆｒとして分担される。 On the other hand, in the structure of the elevator apparatus of Example 1, when the steel plate 7 is closed as shown in FIG. As shown in FIG. 5, this vertical load Fw is shared as a shared load Fr by the support member 8 without being borne by the hinge 9 .
　また、図２に示すように、鋼板７と、その直下にある構造物６においても、垂直荷重Ｆｗは荷重分担される。即ち、従来の保守用足場の回動端と比較して、実施例１の鋼板７の回動端は、強固になる作用が得られる。 In addition, as shown in FIG. 2, the vertical load Fw is also shared between the steel plate 7 and the structure 6 directly below it. That is, compared with the rotating end of the conventional scaffolding for maintenance, the rotating end of the steel plate 7 of Example 1 has the effect of becoming stronger.
　従って、実施例１のエレベーター装置は、従来のエレベーター装置と比較して、鋼板７の回動端の強度が増すという効果が得られる。更に、保守用足場の不安定なども解消されるため、保守作業を行う際に安心に作業を実施することができる。 Therefore, the elevator device of Example 1 has the effect of increasing the strength of the rotating end of the steel plate 7 compared to the conventional elevator device. Furthermore, since the instability of the scaffold for maintenance is eliminated, maintenance work can be carried out with peace of mind.
　このように本実施例によれば、上記のような構成のエレベーター装置の乗りかご１で、乗りかご１の天井部に、この天井部を覆うように鋼板７を設けることで、乗りかご１のサイズが小さい場合においても、保守作業員の退避スペースを２人以上は確保することができる。 As described above, according to the present embodiment, the car 1 of the elevator apparatus configured as described above is provided with the steel plate 7 on the ceiling of the car 1 so as to cover the ceiling. Even if the size is small, it is possible to secure an evacuation space for two or more maintenance workers.
　また、鋼板７を手摺１２などに取り付けることで、乗りかご１の上で作業をする保守作業員の落下や転落防止にもなり、安全性が向上する。 In addition, by attaching the steel plate 7 to the handrail 12 or the like, the maintenance worker working on the car 1 can be prevented from falling or falling, improving safety.
　次に、図２及び図６を用いて、本発明のエレベーター装置の実施例２について説明する。 Next, a second embodiment of the elevator device of the present invention will be described with reference to FIGS. 2 and 6. FIG.
　上述した実施例１では、乗りかご１において、鋼板７が乗りかご１よりも上方に配置されていたが、実施例２では、図６に示すように、昇降路１７を昇降する乗りかご１を備えていると共に、昇降路１７において最上階より上方の昇降路１７の頂部付近に巻上機１９を備え、また、かご側ガイドレール２０と釣合い重り側ガイドレール２１及び両者に直交する方向に接続されたマシンビーム１８を有し、かご側ガイドレール２０と釣合い重り側ガイドレール２１及びマシンビーム１８が巻上機１９を支持するように配置され、巻上機１９と乗りかご１とが主ロープ２２で接続される点が、実施例１とは異なる構成である。 In the first embodiment described above, in the car 1, the steel plate 7 is arranged above the car 1, but in the second embodiment, as shown in FIG. In addition, a hoist 19 is provided near the top of the hoistway 17 above the top floor in the hoistway 17, and a car-side guide rail 20 and a counterweight-side guide rail 21 are connected in a direction orthogonal to both. The car-side guide rails 20, the counterweight-side guide rails 21 and the machine beam 18 are arranged to support the hoisting machine 19, and the hoisting machine 19 and the car 1 are connected to the main rope. 22 is a different configuration from the first embodiment.
　図６に示すように、実施例２は、実施例１と以下の点においては同一である。即ち、乗りかご１の上方に横梁５が配置され、この横梁５の上方において、手摺１２と、この手摺１２を乗りかご１の奥行方向（図６の左右方向）に対して手前側と奥側で支持する第１の手摺用支柱１１ａと、中間で支持す第２の手摺用支柱１１ｂと、構造物６と、支持材８とを有し、構造物６の上方に鋼板７が配置され、支持材８に接続されたヒンジ９に対して鋼板７は回動可能に支持され、かつ、第１の手摺用支柱１１ａ及び第２の手摺用支柱１１ｂの側面にある長穴１４ａ及び１４ｂに通された締結具１０ａ及び１０ｂによって、脱着可能で、かつ、自由自在に係合されている点である。 As shown in FIG. 6, Example 2 is the same as Example 1 in the following points. That is, a horizontal beam 5 is arranged above the car 1, and above the horizontal beam 5, a handrail 12 is arranged on the near side and the far side with respect to the depth direction of the car 1 (horizontal direction in FIG. 6). a first handrail support column 11a supported by a second handrail support column 11b supported in the middle, a structure 6, and a support member 8, and a steel plate 7 is arranged above the structure 6, A steel plate 7 is rotatably supported by a hinge 9 connected to a support member 8, and passes through long holes 14a and 14b on the side surfaces of the first handrail post 11a and the second handrail post 11b. It is detachable and freely engaged by the fasteners 10a and 10b.
　また、鋼板７は、その回動端に補強用リブ１５を有していると共に、支持材８には切り欠き１６が形成された構造を有し、前述した係合の解除動作をすることにより、鋼板７の閉じられた上面において、保守作業員の退避スペースは２人以上得られると共に、鋼板７の回動端は、従来のエレベーター装置に備えられた保守用足場の回動端と比較して、安全性が増加する点は実施例１と同じである。 Further, the steel plate 7 has a reinforcing rib 15 at its rotating end, and has a structure in which a notch 16 is formed in the supporting member 8. At the closed upper surface of the steel plate 7, the evacuation space for two or more maintenance workers can be obtained, and the rotating end of the steel plate 7 is compared with the rotating end of the maintenance scaffold provided in the conventional elevator device. This is the same as in Example 1 in terms of increased safety.
　図６は、昇降路１７の最上階にあるエレベーター装置の要部を省略した図であるが、図６に示すように、鋼板７の上面において保守作業員が保守作業を行う。 FIG. 6 is a diagram omitting the essential parts of the elevator device on the top floor of the hoistway 17, but as shown in FIG.
　具体的に説明すると、保守作業員は、乗りかご１上の鋼板７の上面に乗り、巻上機１９のブレーキの点検又は交換を行う場合には、通常であれば乗りかご１の天井面１ａを基準とし、その基準面を足場の高さを０ｍｍとした際に、構造物６より高い位置に鋼板７を配置した場合の高さ（図６の符号Ｌ）を例えば３００ｍｍとすると、乗りかご１の天井面１ａの高さの差分は、乗りかご１の天井面１ａを保守面とした場合と比較して、昇降路１７の頂部に設置している巻上機１９へのアクセスは容易となり、足場から保守作業員の手の先端までの巻上機１９までの距離が短縮でき、保守作業員の保守作業性を向上させることができる。 Specifically, when a maintenance worker rides on the upper surface of the steel plate 7 on the car 1 and inspects or replaces the brake of the hoist 19, the maintenance worker normally checks the ceiling surface 1a of the car 1. When the height of the scaffolding is set to 0 mm on the reference plane, and the height (mark L in FIG. 6) when the steel plate 7 is arranged at a position higher than the structure 6 is set to 300 mm, for example, 1 makes it easier to access the hoisting machine 19 installed at the top of the hoistway 17 compared to the case where the ceiling surface 1a of the car 1 is used as the maintenance surface. , the distance from the scaffold to the tip of the maintenance worker's hand to the hoisting machine 19 can be shortened, and the maintenance workability of the maintenance worker can be improved.
　従って、実施例２のエレベーター装置は、昇降路１７の最上階付近において、頂部にある巻上機１９などを保守する場合に作業性及び足場が水平で平坦であることで安全性を向上させる効果がある。 Therefore, the elevator apparatus of the second embodiment has the effect of improving workability and safety when maintaining the hoisting machine 19 and the like at the top near the top floor of the hoistway 17 because the scaffolding is horizontal and flat. There is
　次に、エレベーター装置の形態を、要退避時及び保守点検時(図２参照)から通常運転時(図１参照)に変える際の動作について、図１、図２、図３、図４（ａ）、図４（ｂ）及び図５を用いて説明する。 Next, FIGS. 1, 2, 3 and 4(a) show the operation when changing the mode of the elevator system from when evacuation is required and during maintenance inspection (see FIG. 2) to normal operation (see FIG. 1). ), FIG. 4(b) and FIG.
　図２に示すように、閉じられた鋼板７は、図５に示すように、鋼板７の回動端にあるヒンジ９を支点に回動させることにより、図３に示すように、第１の手摺用支柱１１ａ及び第２の手摺用支柱１１ｂの近傍に垂直に立てられ（垂直に立てられた鋼板を符号７´で示す）、更に、図４（ａ）、図４（ｂ）に示した係合動作をすることにより、第１の手摺用支柱１１ａ及び第２の手摺用支柱１１ｂと係合される。 As shown in FIG. 2, the closed steel plate 7 is rotated about the hinge 9 at the end of the rotation of the steel plate 7 as shown in FIG. It is erected vertically near the handrail support 11a and the second handrail support 11b (the vertically erected steel plate is indicated by reference numeral 7'), and further shown in FIGS. 4(a) and 4(b) By performing an engaging operation, it is engaged with the first handrail post 11a and the second handrail post 11b.
　図６に示す昇降路１７の中間階及び低層階において、前述した図１に示すエレベーター装置の形態で保守作業をする場合、図１に示すように、乗りかご１の奥行側と手前側の第１の手摺用支柱１１ａの間の開口部が、鋼板７によって中段高さ程度まで塞がれる。 When performing maintenance work on the intermediate floors and lower floors of the hoistway 17 shown in FIG. 6 in the form of the elevator apparatus shown in FIG. The opening between the 1 handrail struts 11a is blocked by the steel plate 7 up to about the middle height.
　これにより、保守作業員が保守する際、前述した開口から昇降路１７へ転落する危険性を防ぐことができる。 As a result, it is possible to prevent the risk of falling from the opening into the hoistway 17 when the maintenance worker performs maintenance.
