The front plate 14 is divided into three in the height direction, and an upper surface plate 15 and a lower surface plate 16 are attached to the vertical frame body 13 in a fixed state with a vertical separation. The central surface plate 17 is detachably attached to the vertical frame body 13 between the upper surface plate 15 and the lower surface plate 16, and is stored and installed in the vertical frame 11 during maintenance and inspection. Can be operated. A call button 8, a landing position indicator 9, and the like are disposed on the central surface plate 17.

中央表板１７は、例えば、矩形平板状の鋼板をＬ字状に折り曲げて作製され、その一端が裏面側にコ字状に曲げられている。取付金２０は、矩形平板状の鋼板を折り曲げて作製され、一方の側辺が他方の側辺２０ａより長く形成されたコ字状体と、コ字状体の一方の側辺の先端から外側にコ字状体の底辺と平行に延設された取付辺２０ｂと、を有する。なお、他方の側辺２０ａと取付辺２０ｂとは直交している。このように作製された取付金２０は、上下に離間して、かつ側辺２０ａを中央表板１７の他端側に向けて、中央表板１７の裏面の他端側に取付辺２０ｂを溶接などにより固着して取り付けられている。   The central surface plate 17 is produced, for example, by bending a rectangular flat steel plate into an L shape, and one end thereof is bent into a U shape on the back surface side. The mounting metal 20 is produced by bending a rectangular flat plate-shaped steel plate, and has a U-shaped body in which one side is formed longer than the other side 20a, and the outer side from the tip of one side of the U-shaped body. And a mounting side 20b extending in parallel with the bottom side of the U-shaped body. The other side 20a and the mounting side 20b are orthogonal to each other. The mounting metal 20 manufactured in this way is vertically separated, the side edge 20a is directed to the other end side of the central surface plate 17, and the mounting edge 20b is welded to the other end side of the back surface of the central surface plate 17. It is fixed and attached by such as.

取付金２１は、中央表板１７と同等の長さの矩形平板状の鋼板をＬ字状に折り曲げて作製されている。取付金２１は、Ｌ字状の基部２１ａの先端側を上表板１５と下表板１６との間に延出させて、かつＬ字状の起立辺２１ｂを上表板１５と下表板１６との間に上下方向に延在させて、縦枠本体１３の側板１３ｂの裏面に基部２１ａを溶接などにより固着して取り付けられている。さらに、永久磁石２２が、取付金２１の起立辺２１ｂの内面に、上下方向に離間して固着されている。なお、永久磁石２２の取付高さ位置は、中央表板１７を縦枠本体１３に装着したときに、取付金２０と同じ高さ位置となるように位置決めされる。   The attachment 21 is manufactured by bending a rectangular flat plate-like steel plate having a length equivalent to that of the central surface plate 17 into an L shape. The mounting metal 21 has the L-shaped base portion 21a extending between the upper surface plate 15 and the lower surface plate 16 and the L-shaped standing side 21b extending between the upper surface plate 15 and the lower surface plate. The base 21a is fixedly attached to the back surface of the side plate 13b of the vertical frame body 13 by welding or the like. Further, the permanent magnet 22 is fixed to the inner surface of the upright side 21b of the attachment 21 so as to be spaced apart in the vertical direction. The mounting height position of the permanent magnet 22 is positioned so as to be the same height position as the mounting bracket 20 when the central face plate 17 is mounted on the vertical frame body 13.

取付金２３は、中央表板１７と同等の長さの矩形平板状の鋼板を折り曲げて作製され、基部２３ａと、基部２３ａの一端から直角に曲げられた取付辺２３ｂと、基部２３ａの他端から直角に、かつ取付辺２３ｂと逆側に曲げられた支持辺２３ｃと、を有する。取付金２３は、支持辺２３ｃを昇降路１と反対側に向けて、上表板１５と下表板１６との間に上下方向に延在させて、取付辺２３ｂを縦枠本体１３の正面板１３ａの折り曲げ辺１３ｃに溶接などにより固着して取り付けられている。永久磁石２４が、取付金２３の基部２３ａの支持辺２３ｃ側の面に、上下方向の中間位置に固着されている。なお、取付金２１の基部２１ａの延出部および縦枠本体１３の折り曲げ辺１３ｃがガイド部材を構成している。   The attachment metal 23 is produced by bending a rectangular flat steel plate having a length equivalent to that of the central surface plate 17, and includes a base 23a, an attachment side 23b bent at a right angle from one end of the base 23a, and the other end of the base 23a. And a support side 23c bent at a right angle from the mounting side 23b. The attachment metal 23 extends in the vertical direction between the upper surface plate 15 and the lower surface plate 16 with the support side 23c facing away from the hoistway 1 so that the attachment side 23b is connected to the vertical frame body 13 in the normal direction. The face plate 13a is fixedly attached to the bent side 13c by welding or the like. The permanent magnet 24 is fixed to the surface on the support side 23c side of the base 23a of the mounting bracket 23 at an intermediate position in the vertical direction. In addition, the extension part of the base 21a of the attachment metal 21 and the bent side 13c of the vertical frame main body 13 constitute a guide member.

ラッチ２５は、ばね（図示せず）により出没状態に保持されるストッパ２６と、ばねの付勢力に抗して引っ張ってストッパ２６を埋没状態に移行させるワイヤ２７と、を有し、取付金２３の支持辺２３ｃの基部２３ａ側の面に固着されている。   The latch 25 includes a stopper 26 that is held in and out by a spring (not shown), and a wire 27 that pulls the spring 26 against the urging force of the spring to shift the stopper 26 to the embedded state. The support side 23c is fixed to the surface on the base 23a side.

保持板２８は、矩形平板状の鋼板をＬ字状に折り曲げて作製され、Ｌ字状の起立辺２８ｂを上方に位置させて、基部２８ａを縦枠本体１３の側板１３ｂと対向する背面板１３ｄに溶接などにより固着されて取り付けられている。解除レバー２９は、一端を乗り場ドア６側に延出させて、背面板１３ｄに直交する軸２９ａ周りに回動可能に背面板１３ｄに取り付けられている。そして、可撓性チューブ３０が、一端を取付金２３の支持辺２３ｃに取り付けられ、他端を保持板２８の起立辺２８ｂに取り付けられて、支持辺２３ｃと起立辺２８ｂとの間に架設されている。ワイヤ２７は、一端がストッパ２６に固定され、可撓性チューブ３０内を通されて起立辺２８ｂ側に引き出され、他端が解除レバー２９の他端に固着されている。なお、ワイヤ２７および解除レバー２９がラッチ解除手段を構成している。   The holding plate 28 is made by bending a rectangular flat plate-shaped steel plate into an L shape, and the rear plate 13d is disposed such that the base 28a faces the side plate 13b of the vertical frame body 13 with the L-shaped standing side 28b positioned upward. It is fixed and attached by welding or the like. One end of the release lever 29 extends toward the landing door 6 and is attached to the back plate 13d so as to be rotatable around an axis 29a orthogonal to the back plate 13d. The flexible tube 30 has one end attached to the support side 23c of the attachment metal 23 and the other end attached to the upright side 28b of the holding plate 28, and is laid between the support side 23c and the upright side 28b. ing. One end of the wire 27 is fixed to the stopper 26, passed through the flexible tube 30, drawn to the standing side 28 b side, and the other end is fixed to the other end of the release lever 29. The wire 27 and the release lever 29 constitute a latch release means.

つぎに、このように構成された乗り場三方枠装置における中央表板１７の着脱動作について説明する。
まず、作業者が、中央表板１７を持って、中央表板１７の一端側のコ字状の折り曲げ部を縦枠本体１３の折り曲げ辺１３ｃにあて、中央表板１７の他端側を取付金２１の基部２１ａの延出部にあてがう。そして、他の作業者が、縦枠１１と乗り場ドア６との間の隙間から治具（図示せず）を差し込んで、解除レバー２９の一端を図３中時計回りに回動させる。これにより、ワイヤ２７が引っ張られ、保持板２８からのワイヤ２７の延出長さが長くなり、ワイヤ２７の一端に連結されたストッパ２６がばねの付勢力に抗して埋没状態となる。 Next, the attaching / detaching operation of the central surface plate 17 in the landing three-way frame device configured as described above will be described.
First, the operator holds the central surface plate 17, places the U-shaped bent portion on one end side of the central surface plate 17 on the bending side 13 c of the vertical frame body 13, and attaches the other end side of the central surface plate 17. It applies to the extended part of the base 21a of the gold 21. Then, another worker inserts a jig (not shown) from the gap between the vertical frame 11 and the landing door 6 and rotates one end of the release lever 29 clockwise in FIG. As a result, the wire 27 is pulled, the extension length of the wire 27 from the holding plate 28 is increased, and the stopper 26 connected to one end of the wire 27 is buried against the urging force of the spring.

そこで、作業者が、乗り場２側から昇降路１側に中央表板１７を押して、折り曲げ辺１３ｃと基部２１ａの延出部の表面に沿ってスライド移動させる。そして、中央表板１７が縦枠本体１３の側板１３ｂに当接すると、中央表板１７の一端側のコ字状の折り曲げ部の先端辺１７ａが取付金２３の基部２３ａに上下方向に離間して固着された永久磁石２４に磁気吸引され、取付金２０の側辺２０ａが取付金２１の起立辺２１ｂに上下方向に離間して固着された永久磁石２２に磁気吸引される。ついで、他の作業者が、解除レバー２９の一端を図３中時計回りに回動させるのを止める。そこで、ストッパ２６がばねの付勢力により延出状態となり、中央表板１７の一端側のコ字状の折り曲げ部の先端辺１７ａと係合し、中央表板１７が縦枠本体１３に取り付けられる。なお、ワイヤ２７が、ストッパ２６の延出に連動して引っ張られ、保持板２８からのワイヤ２７の延出長さが短くなり、解除レバー２９が初期位置に復帰する。   Therefore, the operator pushes the central surface plate 17 from the landing 2 side to the hoistway 1 side, and slides it along the surfaces of the bent side 13c and the extending portion of the base portion 21a. When the central surface plate 17 comes into contact with the side plate 13 b of the vertical frame body 13, the distal end side 17 a of the U-shaped bent portion on one end side of the central surface plate 17 is separated vertically from the base portion 23 a of the attachment metal 23. Thus, the side 20a of the mounting metal 20 is magnetically attracted to the permanent magnet 22 that is fixed to the upright side 21b of the mounting metal 21 in the vertical direction. Next, another worker stops turning one end of the release lever 29 clockwise in FIG. Therefore, the stopper 26 is extended by the urging force of the spring, engages with the distal end side 17 a of the U-shaped bent portion on one end side of the central surface plate 17, and the central surface plate 17 is attached to the vertical frame body 13. . The wire 27 is pulled in conjunction with the extension of the stopper 26, the extension length of the wire 27 from the holding plate 28 is shortened, and the release lever 29 returns to the initial position.

縦枠本体１３に取り付けられた中央表板１７においては、中央表板１７の昇降路１側から乗り場２側への移動は、先端辺１７ａがストッパ２６に当接し、阻止される。また、中央表板１７の乗り場ドア６の閉方向の移動は、取付金２０の側辺２０ａが取付金２１の基部２１ａに当接し、阻止される。さらに、中央表板１７が縦枠本体１３に取り付けられた上表板１５と下表板１６とに挟持されており、中央表板１７の上下方向の移動が阻止される。   In the central surface plate 17 attached to the vertical frame body 13, the movement of the central surface plate 17 from the hoistway 1 side to the landing 2 side is prevented by the tip side 17 a coming into contact with the stopper 26. Further, the movement of the center door plate 17 in the closing direction of the landing door 6 is prevented by the side 20a of the attachment metal 20 coming into contact with the base 21a of the attachment metal 21. Further, the central surface plate 17 is sandwiched between an upper surface plate 15 and a lower surface plate 16 attached to the vertical frame body 13, and the vertical movement of the central surface plate 17 is prevented.

ついで、作業者が、縦枠１１と乗り場ドア６との間の隙間から治具（図示せず）を差し込んで、解除レバー２９の一端を図３中時計回りに回動させる。これにより、保持板２８からのワイヤ２７の延出長さが長くなり、ワイヤ２７の一端に連結されたストッパ２６がばねの付勢力に抗して埋没状態となり、ストッパ２６と先端辺１７ａとの係合状態が解除される。そこで、他の作業者が、中央表板１７を持って永久磁石２２，２４の磁気吸引力に抗して昇降路１側から乗り場２側に引っ張る。これにより、中央表板１７が折り曲げ辺１３ｃと基部２１ａの延出部の表面に沿ってスライド移動し、乗り場２側に引き出される。そして、中央表板１７が取り外されて縦枠本体１３に形成された開口から制御装置７を操作して、エレベータの保守点検を行うことになる。   Next, the operator inserts a jig (not shown) through the gap between the vertical frame 11 and the landing door 6 and rotates one end of the release lever 29 clockwise in FIG. As a result, the extension length of the wire 27 from the holding plate 28 is increased, the stopper 26 connected to one end of the wire 27 is buried against the urging force of the spring, and the stopper 26 and the distal end side 17a are in contact with each other. The engaged state is released. Therefore, another worker holds the central surface plate 17 and pulls it from the hoistway 1 side to the landing 2 side against the magnetic attractive force of the permanent magnets 22 and 24. Thereby, the center surface board 17 slides along the surface of the bending part 13c and the extension part of the base part 21a, and is pulled out to the landing 2 side. Then, the central surface plate 17 is removed and the control device 7 is operated from the opening formed in the vertical frame main body 13 to perform maintenance and inspection of the elevator.

この実施の形態１によれば、中央表板１７が、取付金２１の基部２１ａの延出部および縦枠本体１３の折り曲げ辺１３ｃに案内されて開口部５に対して接近する方向および離反する方向に移動して縦枠本体１３に着脱可能に取り付けられているので、中央表板１７の取付時に、中央表板１７と上表板１５との合わせ部、中央表板１７と下表板１６との合わせ部、さらには中央表板１７と縦枠本体１３との合わせ部に隙間を確保する必要がなく、意匠性が高められる。
中央表板１７の抜けを阻止するラッチ２５、ラッチ２５のストッパ２６と中央表板１７の先端辺１７ａとの係合を解除するワイヤ２７、可撓性チューブ３０、保持板２８、解除レバー２９が縦枠１１の意匠面に配置されていないので、意匠性が高められる。 According to the first embodiment, the central surface plate 17 is guided by the extending portion of the base portion 21a of the mounting metal 21 and the bent side 13c of the vertical frame main body 13 so as to approach and separate from the opening 5. Since it is moved in the direction and is detachably attached to the vertical frame body 13, when the central surface plate 17 is attached, the mating portion of the central surface plate 17 and the upper surface plate 15, the central surface plate 17 and the lower surface plate 16 It is not necessary to secure a gap in the mating portion, and further in the mating portion between the central surface plate 17 and the vertical frame main body 13, and the design is improved.
A latch 25 for preventing the central surface plate 17 from coming off, a wire 27 for releasing the engagement between the stopper 26 of the latch 25 and the distal end side 17a of the central surface plate 17, a flexible tube 30, a holding plate 28, and a release lever 29 are provided.

図４乃至図８において、中央表板１７Ａは、矩形平板状の鋼板をＬ字状に折り曲げて作製され、その一端が裏面側にコ字状に曲げられている。そして、図７に示されるように、上下方向に延在するコ字状部の一部が切り欠かれ、Ｌ字状となっている。
取付金２３Ａは、取付金２３の約半分の長さに作製され、基部２３ａと、基部２３ａの一端から直角に曲げられた取付辺２３ｂと、基部２３ａの他端から直角に、かつ取付辺２３ｂと逆側に曲げられた支持辺２３ｃと、を有する。そして、２つの取付金２３Ａが、上下方向に所定距離離間して、支持辺２３ｃを昇降路１と反対側に向けて、上表板１５と下表板１６との間に上下方向に延在させて、取付辺２３ｂを縦枠本体１３の正面板１３ａの折り曲げ辺１３ｃに溶接などにより固着して取り付けられている。なお、２つの取付金２３Ａの間には、中央表板１７Ａのコ字状部の一部を切り欠いて作製されたＬ字状の部位が位置している。 4 to 8, the central surface plate 17A is produced by bending a rectangular flat steel plate into an L shape, and one end thereof is bent into a U shape on the back surface side. And as FIG. 7 shows, a part of U-shaped part extended to an up-down direction is notched, and it is L-shaped.
The attachment metal 23A is manufactured to be approximately half the length of the attachment metal 23, and includes a base 23a, an attachment side 23b bent at a right angle from one end of the base 23a, a right angle from the other end of the base 23a, and an attachment side 23b. And a support side 23c bent to the opposite side. Then, the two mounting brackets 23A are separated from each other by a predetermined distance in the vertical direction, and extend in the vertical direction between the upper surface plate 15 and the lower surface plate 16 with the support side 23c facing away from the hoistway 1. The attachment side 23b is fixedly attached to the bent side 13c of the front plate 13a of the vertical frame body 13 by welding or the like. An L-shaped part produced by cutting out a part of the U-shaped part of the central surface plate 17A is located between the two attachments 23A.

スライド板３５は、図８に示されるように、矩形平板状の鋼板を長さ方向の略中央位置でＬ字状に折り曲げて作製されている。そして、穴方向を長さ方向とするガイド穴３６がスライド板３５の基部３５ａの幅方向の中央位置に穿設され、ばね取付穴３７がスライド板３５の起立辺３５ｂの根元側の幅方向両側に穿設され、ワイヤ取付穴３８が起立辺３５ｂの先端側の幅方向中央に穿設されている。
スライド板３５は、２つの取付金２３Ａの間の位置に、基部３５ａを昇降路１側に向けて折り曲げ辺１３ｃに宛がわれ、ねじ３９をガイド穴３６に通して折り曲げ辺１３ｃに螺着して、開口部５に対して接離する方向（接近する方向と離反する方向）にスライド移動可能に取り付けられている。 As shown in FIG. 8, the slide plate 35 is manufactured by bending a rectangular flat plate-shaped steel plate into an L shape at a substantially central position in the length direction. A guide hole 36 whose length direction is the hole direction is formed in the center position in the width direction of the base portion 35a of the slide plate 35, and the spring mounting holes 37 are on both sides in the width direction on the root side of the rising side 35b of the slide plate 35. The wire attachment hole 38 is formed in the center in the width direction on the distal end side of the standing side 35b.
The slide plate 35 is addressed to the bent side 13c with the base 35a facing the hoistway 1 side at a position between the two mounting brackets 23A, and a screw 39 is passed through the guide hole 36 and screwed to the bent side 13c. Thus, it is attached so as to be slidable in a direction approaching and separating from the opening 5 (a direction away from the approaching direction).

固定板４０は、図９に示されるように、コ字形平板状の鋼板のコ字形の両側辺の端部側をＬ字状に折り曲げて作製されている。そして、ばね取付穴４１が固定板４０のコ字形の基部４０ａの両側辺にそれぞれ穿設され、ワイヤ挿通穴４２がコ字形の基部４０ａの底辺の幅方向中央に穿設されている。
固定板４０は、図１０の（ａ），（ｂ）に示されるように、基部４０ａを昇降路１側に向けて、スライド板３５の起立辺３５ｂと相対して、取付辺４０ｂを折り曲げ辺１３ｃに溶接などにより固着されて取り付けられている。なお、固定板４０は、中央表板１７Ａのコ字状部の一部を切り欠いて作製されたＬ字状の部位の昇降路１側に位置している。また、スライド板３５は、コ字形の基部４０ａの両側辺間に位置している。 As shown in FIG. 9, the fixing plate 40 is manufactured by bending the end portions of both sides of the U-shaped flat steel plate into an L shape. Spring mounting holes 41 are formed in both sides of the U-shaped base 40a of the fixing plate 40, and wire insertion holes 42 are formed in the center in the width direction of the bottom of the U-shaped base 40a.
As shown in FIGS. 10A and 10B, the fixing plate 40 has a base 40 a directed toward the hoistway 1 and is opposed to the rising side 35 b of the slide plate 35, and the attachment side 40 b is bent. It is fixedly attached to 13c by welding or the like. The fixed plate 40 is located on the hoistway 1 side of an L-shaped part produced by cutting out a part of the U-shaped portion of the central surface plate 17A. The slide plate 35 is located between both sides of the U-shaped base 40a.

そして、一対の復帰ばね４３が、両端をスライド板３５の起立辺３５ｂに形成されたばね取付穴３７と固定板４０の基部４０ａに形成されたばね取付穴４１とに固定されて、張設状態に取り付けられている。これにより、復帰ばね４３の付勢力が、スライド板３５を固定板４０に接近する方向に作用し、スライド板３５は、図１０の（ｂ）に示されるように、ガイド穴３６の昇降路１側の端部がねじ３９に当接する位置に保持される。
また、ワイヤ２７は、図６および図７に示されるように、一端がストッパ２６に固定され、可撓性チューブ３０内を通されて基部４０ａに形成されたワイヤ挿通穴４２から引き出され、他端がスライド板３５の起立辺３５ｂに形成されたワイヤ取付穴３８に固着されている。ワイヤ２７、スライド板３５、固定板４０、復帰ばね４３がラッチ解除手段を構成している。
なお、他の構成は上記実施の形態１と同様に構成されている。 A pair of return springs 43 are fixed at both ends to spring mounting holes 37 formed on the rising side 35b of the slide plate 35 and spring mounting holes 41 formed on the base 40a of the fixing plate 40, and attached in a stretched state. It has been. As a result, the urging force of the return spring 43 acts in the direction in which the slide plate 35 approaches the fixed plate 40, and the slide plate 35 moves up and down the hoistway 1 of the guide hole 36 as shown in FIG. The side end is held at a position where it abuts against the screw 39.
As shown in FIGS. 6 and 7, one end of the wire 27 is fixed to the stopper 26, passed through the flexible tube 30, and drawn out from a wire insertion hole 42 formed in the base 40a. The end is fixed to a wire attachment hole 38 formed in the rising side 35 b of the slide plate 35. The wire 27, the slide plate 35, the fixed plate 40, and the return spring 43 constitute latch release means.
Other configurations are the same as those in the first embodiment.

つぎに、このように構成された乗り場三方枠装置における中央表板１７Ａの着脱動作について説明する。
まず、作業者が、鋼尺（図示せず）を持って折り曲げ辺１３ｃに沿わせてスライド板３５を昇降路１側に押す。これにより、スライド板３５が折り曲げ辺１３ｃ上を昇降路１側にスライド移動する。そこで、ワイヤ２７が引っ張られ、固定板４０からのワイヤ２７の延出長さが長くなり、ワイヤ２７の一端に連結されたストッパ２６がばねの付勢力に抗して埋没状態となる。 Next, the attaching / detaching operation of the central surface plate 17A in the landing three-way frame device configured as described above will be described.
First, an operator holds a steel ruler (not shown) and pushes the slide plate 35 toward the hoistway 1 along the bent side 13c. Thereby, the slide plate 35 slides on the bent side 13c to the hoistway 1 side. Therefore, the wire 27 is pulled, the extension length of the wire 27 from the fixing plate 40 is increased, and the stopper 26 connected to one end of the wire 27 is buried against the urging force of the spring.

ついで、他の作業者が、中央表板１７Ａを持って、中央表板１７Ａの一端側のコ字状の折り曲げ部を縦枠本体１３の折り曲げ辺１３ｃに近づけ、中央表板１７Ａの他端側を取付金２１の基部２１ａの延出部にあてがう。そこで、他の作業者が、乗り場２側から昇降路１側に中央表板１７Ａを押して、基部２１ａの延出部の表面に沿ってスライド移動させる。そして、中央表板１７Ａが縦枠本体１３の側板１３ｂに当接すると、中央表板１７Ａの一端側のコ字状の折り曲げ部の先端辺１７ａが取付金２３の基部２３ａに上下方向に離間して固着された永久磁石２４に磁気吸引され、取付金２０の側辺２０ａが取付金２１の起立辺２１ｂに上下方向に離間して固着された永久磁石２２に磁気吸引される。   Next, another operator holds the central surface plate 17A and brings the U-shaped bent portion on one end side of the central surface plate 17A closer to the bending side 13c of the vertical frame body 13 so that the other end side of the central surface plate 17A. Is applied to the extending portion of the base 21a of the attachment 21. Therefore, another worker pushes the central surface plate 17A from the landing 2 side to the hoistway 1 side and slides it along the surface of the extending portion of the base portion 21a. When the central surface plate 17A comes into contact with the side plate 13b of the vertical frame main body 13, the distal end side 17a of the U-shaped bent portion on one end side of the central surface plate 17A is separated vertically from the base portion 23a of the mounting bracket 23. Thus, the side 20a of the mounting metal 20 is magnetically attracted to the permanent magnet 22 that is fixed to the upright side 21b of the mounting metal 21 in the vertical direction.

ついで、作業者が、鋼尺を引き抜く。そこで、ストッパ２６がばねの付勢力により延出状態となり、中央表板１７Ａの一端側のコ字状の折り曲げ部の先端辺１７ａと係合し、中央表板１７Ａの一端側のコ字状の折り曲げ部が折り曲げ辺１３ｃに接し、中央表板１７Ａが縦枠本体１３に取り付けられる。なお、ワイヤ２７が、ストッパ２６の延出に連動して引っ張られ、固定板４０からのワイヤ２７の延出長さが短くなり、スライド板３５が初期位置に復帰する。   Next, the operator pulls out the steel ruler. Accordingly, the stopper 26 is extended by the urging force of the spring, engages with the distal end side 17a of the U-shaped bent portion on one end side of the center surface plate 17A, and the U-shape on one end side of the center surface plate 17A. The bent portion is in contact with the bent side 13c, and the central surface plate 17A is attached to the vertical frame body 13. The wire 27 is pulled in conjunction with the extension of the stopper 26, the extension length of the wire 27 from the fixed plate 40 is shortened, and the slide plate 35 returns to the initial position.

縦枠本体１３に取り付けられた中央表板１７Ａにおいては、中央表板１７Ａの昇降路１側から乗り場２側への移動は、先端辺１７ａがストッパ２６に当接し、阻止される。また、中央表板１７Ａの乗り場ドア６の閉方向の移動は、取付金２０の側辺２０ａが取付金２１の基部２１ａに当接し、阻止される。さらに、中央表板１７Ａが縦枠本体１３に取り付けられた上表板１５と下表板１６とに挟持されており、中央表板１７Ａの上下方向の移動が阻止される。   In the central surface plate 17A attached to the vertical frame main body 13, the movement of the central surface plate 17A from the hoistway 1 side to the landing 2 side is prevented by the tip side 17a coming into contact with the stopper 26. Further, the movement of the center surface plate 17 </ b> A in the closing direction of the landing door 6 is prevented by the side 20 a of the attachment metal 20 coming into contact with the base 21 a of the attachment metal 21. Further, the central surface plate 17A is sandwiched between the upper surface plate 15 and the lower surface plate 16 attached to the vertical frame body 13, and the vertical movement of the central surface plate 17A is prevented.

ついで、作業者が、中央表板１７Ａを持って中央表板１７Ａの一端側のコ字状の折り曲げ部と折り曲げ辺１３ｃとの間に０．５ｍｍ程度の隙間をあける。ついで、他の作業者が、鋼尺をその隙間から差し込で、スライド板３５を昇降路１側にスライド移動させる。これにより、固定板４０からのワイヤ２７の延出長さが長くなり、ワイヤ２７の一端に連結されたストッパ２６がばねの付勢力に抗して埋没状態となり、ストッパ２６と先端辺１７ａとの係合状態が解除される。そこで、作業者が、中央表板１７Ａを持って永久磁石２２，２４の磁気吸引力に抗して昇降路１側から乗り場２側に引っ張る。これにより、中央表板１７Ａが基部２１ａの延出部の表面に沿ってスライド移動し、乗り場２側に引き出される。そして、中央表板１７Ａが取り外されて縦枠本体１３に形成された開口から制御装置７を操作して、エレベータの保守点検を行うことになる。   Next, the operator holds the central surface plate 17A and opens a gap of about 0.5 mm between the U-shaped bent portion on one end side of the central surface plate 17A and the bent side 13c. Next, another worker inserts a steel rule from the gap and slides the slide plate 35 toward the hoistway 1 side. As a result, the extension length of the wire 27 from the fixing plate 40 is increased, the stopper 26 connected to one end of the wire 27 is buried against the urging force of the spring, and the stopper 26 and the distal end side 17a The engaged state is released. Therefore, the operator holds the central surface plate 17A and pulls it from the hoistway 1 side to the landing 2 side against the magnetic attractive force of the permanent magnets 22 and 24. As a result, the central surface plate 17A slides along the surface of the extending portion of the base portion 21a and is pulled out to the landing 2 side. Then, the maintenance and inspection of the elevator is performed by operating the control device 7 from the opening formed in the vertical frame body 13 with the central surface plate 17A removed.

このように、実施の形態２においても、中央表板１７Ａが、取付金２１の基部２１ａの延出部に案内されて開口部５に対して接近する方向および離反する方向に移動して縦枠本体１３に着脱可能に取り付けられているので、中央表板１７Ａの取付時に、中央表板１７Ａと上表板１５との合わせ部、中央表板１７Ａと下表板１６との合わせ部、さらには中央表板１７Ａと縦枠本体１３との合わせ部に隙間を確保する必要がなく、意匠性が高められる。
中央表板１７Ａの抜けを阻止するラッチ２５、ラッチ２５のストッパ２６と中央表板１７Ａの先端辺１７ａとの係合を解除するワイヤ２７、可撓性チューブ３０、固定板４０、スライド板３５が縦枠１１の意匠面に配置されていないので、意匠性が高められる。 Thus, also in the second embodiment, the central surface plate 17A is guided by the extending portion of the base portion 21a of the attachment metal 21 and moves in the direction approaching and separating from the opening 5, thereby causing the vertical frame Since it is detachably attached to the main body 13, when the central surface plate 17A is attached, the alignment portion between the central surface plate 17A and the upper surface plate 15, the alignment portion between the central surface plate 17A and the lower surface plate 16, and There is no need to secure a gap in the mating portion between the central surface plate 17A and the vertical frame body 13, and the design is improved.
A latch 25 for preventing the central surface plate 17A from coming off, a wire 27 for releasing the engagement between the stopper 26 of the latch 25 and the distal end side 17a of the central surface plate 17A, a flexible tube 30, a fixed plate 40, and a slide plate 35 are provided. Since it is not arrange | positioned at the design surface of the vertical frame 11, the designability is improved.

ラッチ解錠手段の操作部であるスライド板３５が中央表板１７Ａに遮蔽されているので、利用者がスライド板３５の存在に気づいてスライド板３５を操作するような事態を未然に回避できる。そこで、利用客がいたずらで中央表板１７Ａを取り外すことができないように錠を付け、さらには、施錠したときに、錠が意匠面から突出しないように構成する必要がなく、低コスト化が図られる。   Since the slide plate 35 which is the operation part of the latch unlocking means is shielded by the central surface plate 17A, it is possible to avoid a situation where the user notices the presence of the slide plate 35 and operates the slide plate 35. Therefore, it is not necessary to provide a lock so that the user cannot remove the central surface plate 17A due to mischief, and further, it is not necessary to configure the lock so that the lock does not protrude from the design surface when locked. It is done.

なお、上記各実施の形態では、中央表板を昇降路（開口部）に対して接離する方向に移動させて縦枠本体に着脱するように構成しているが、中央表板を乗り場ドアの開閉方向に移動させて縦枠本体に着脱するように構成してもよい。   In each of the above embodiments, the central surface plate is moved in the direction of contact with and away from the hoistway (opening) and is attached to and detached from the vertical frame body. It may be configured to be attached to and detached from the vertical frame body by moving in the opening and closing direction.
