Abstract

PROBLEM TO BE SOLVED: To provide a passenger conveyor in which an edge on a footstep side of a getting-on and getting-off plate does not become a fulcrum when lifting a conveyor entrance side of the getting-on and getting-off plate by configuring the passenger conveyor so that edges on both sides of the getting-on and getting-off plate do not come into contact with a support frame below the same when opening/closing the getting-on and getting-off plate.SOLUTION: A passenger conveyor is configured so that a lower part support 15c of a U-shaped cross sectional reinforcing material 15 is extended, and an edge 12a' on a footstep side of a getting-on and getting-off plate does not come into contact with a support frame 4 below the same when performing opening/closing work of the getting-on and getting-off plate by lifting a conveyor entrance side of the getting-on and getting-off plate 12.

Description

本発明の実施形態は、乗客コンベアに関する。 Embodiments of the present invention relate to a passenger conveyor.

通常、乗客コンベア１は、図１及び図２に示すように、循環移動する無端状に連結された複数の踏段３を備え、踏段３への乗降口には機械室の開閉板となる乗降板２が配されている。当該乗降板２は、通常、複数に分割した長方形状の板より構成されており、図３に示すように、踏段側に向かって左右両端に設けられた支持枠４の上に踏段側から乗り場側に向かって並列に設置されてボルト止めされる。支持枠４は、建屋との区切りとなる垂直パネル４ａと垂直パネル４ａに取り付けられたＬ字パネル４ｂとから構成されている。また、当該乗降板２を構成する天板２ａの表面には乗降客の滑り止めと意匠性とを兼ね備えたエッチング模様が施されている。 As shown in FIGS. 1 and 2, the passenger conveyor 1 normally includes a plurality of steps 3 connected in an endless manner that circulates, and a boarding / exiting plate that serves as an opening / closing plate for a machine room at the boarding / exiting step 3. 2 is arranged. The boarding / alighting plate 2 is usually composed of a rectangular plate divided into a plurality of parts, and as shown in FIG. 3, the boarding / exiting plate 2 is placed on the support frames 4 provided at both the left and right sides from the step side. Installed in parallel toward the side and bolted. The support frame 4 is composed of a vertical panel 4a serving as a partition from the building and an L-shaped panel 4b attached to the vertical panel 4a. The surface of the top plate 2a constituting the boarding / alighting plate 2 is provided with an etching pattern that has both slipperiness and design for passengers.

また、従来の乗降板１０２は、図２２及び図２４に示すように、その踏段側及び乗り場側の両端部に、隣接する乗降板と間に段差が生じないように段差防止金具２ｂが取り付けられている。当該段差防止金具２ｂは、図２１に示すように、乗降板踏段側に２箇所、乗降板乗り場側に１箇所取り付けられている。 Further, as shown in FIGS. 22 and 24, the conventional boarding board 102 is provided with step prevention metal fittings 2b at both ends on the step side and the landing side so as not to cause a level difference between adjacent boarding boards. ing. As shown in FIG. 21, the level difference prevention metal fitting 2b is attached at two places on the boarding board step side and at one place on the boarding board landing side.

前記乗降板２の天板２ａは通常１〜２ｍｍ厚程度の鋼板をプレスして製作されるものであり、天板２ａ単体では利用者が通過する際の荷重を支えることができない。そのため、従来は、乗降板天板の下面に図２３に示す断面コの字型の補強材１０５を、図２１及び図２２に示すように溶接して強度を増大させている。この補強材１０５は、図２４に示すように、その底面が前記のＬ字形をなすＬ字パネル４ｂの底面上に載置されることにより乗降板２を支承する。この補強材１０５は、図２２及び図２７に示すように、天板１０２ａの端縁１０２ａ’から１０〜２０ｍｍの間を除いて設置されている。 The top plate 2a of the boarding / alighting plate 2 is usually manufactured by pressing a steel plate having a thickness of about 1 to 2 mm, and the top plate 2a alone cannot support a load when a user passes. Therefore, conventionally, a U-shaped reinforcing member 105 having a U-shaped cross-section shown in FIG. 23 is welded to the lower surface of the boarding board to increase the strength as shown in FIGS. As shown in FIG. 24, the reinforcing member 105 supports the boarding / alighting plate 2 by placing the bottom surface on the bottom surface of the L-shaped panel 4b having the L-shape. As shown in FIGS. 22 and 27, the reinforcing member 105 is installed except for 10 to 20 mm from the end edge 102a 'of the top plate 102a.

そして、乗客コンベアの保守点検時には乗降板１０２の開閉作業が行われるが、その際には、図２５及び図２６に示すように、乗降板１０２の踏段側を支点にして乗り場側を持ち上げることとなる。従来の乗降板１０２は、例えば図２７に示す状態から図２８に示す状態までの傾斜角αの間は、補強材１０５の下端１０５’とＬ字パネル４ｂの底面４ｂ’との接触点を支点として、乗降板１０２の乗り場側を持ち上げることになるため、天板端縁１０２ａ’には影響が及ばない。しかし、乗降板１０２を前記の傾斜角αを超えて持ち上げると、補強材１０５は、天板１０２ａの端縁１０２ａ’には達していないことにより乗降板踏段側の天板端縁１０２ａ’とＬ字パネル４ｂの頂部４ｂ’’との接触が回避できない。その結果、図２９に示すように、補強材１０５の下端１０５’が浮き上がって、Ｌ字パネル４ｂの頂部４ｂ’’と天板端縁１０２ａ’との接触点を支点として、図２６のＢに示す接触状態で乗降板を持ち上げることになる。したがって、乗降板踏段側の天板端縁１０２ａ’に乗降板１０２の全重量が掛かってしまうことになる。 When the passenger conveyor is maintained and inspected, the board 102 is opened and closed. At that time, as shown in FIGS. 25 and 26, the landing side is lifted with the step side of the board 102 as a fulcrum. Become. For example, during the inclination angle α from the state shown in FIG. 27 to the state shown in FIG. 28, the conventional boarding board 102 has a contact point between the lower end 105 ′ of the reinforcing member 105 and the bottom surface 4 b ′ of the L-shaped panel 4 b as a fulcrum. Since the boarding side of the boarding board 102 is lifted, the top board edge 102a ′ is not affected. However, when the boarding / alighting plate 102 is lifted beyond the inclination angle α, the reinforcing material 105 does not reach the edge 102a ′ of the top board 102a, so that the top board edge 102a ′ on the boarding / alighting board step side and L Contact with the top 4b '' of the character panel 4b cannot be avoided. As a result, as shown in FIG. 29, the lower end 105 ′ of the reinforcing member 105 is lifted, and the contact point between the top 4b ″ of the L-shaped panel 4b and the top edge 102a ′ is used as a fulcrum in FIG. The boarding board will be lifted in the contact state shown. Therefore, the total weight of the boarding / alighting plate 102 is applied to the top plate edge 102a 'on the boarding / alighting board step side.

本発明が解決しようとする課題は、乗降板を開閉する際に、乗降板の両側部の端縁が、その下方の支持枠と接触しないように構成することにより、乗降板の乗り場側の持ち上げ時に乗降板の踏段側の端縁が支点にならない乗客コンベアを提供することである。 The problem to be solved by the present invention is that when the board is opened and closed, the edge of the both sides of the board is not in contact with the lower support frame, so that the board is lifted on the landing side. It is sometimes to provide a passenger conveyor in which the step edge of the boarding board is not a fulcrum.

本発明の実施形態に係る乗客コンベアは、前記の断面コの字型の補強材の下部支えを延長し、乗降板の乗り場側を持ち上げて乗降板の開閉作業を行う際に、乗降板の踏段側の端縁が、その下方の支持枠と接触しない構成としたことにある。 The passenger conveyor according to the embodiment of the present invention extends the lower support of the U-shaped reinforcing member in cross section and lifts the boarding side of the boarding board to open and close the boarding board when the boarding board is opened and closed. That is, the side edge is not in contact with the lower support frame.

以下、本発明の実施の形態に係る乗客コンベアについて、図面を参照して説明する。なお、乗客コンベアの概略構成は、背景技術の項で述べたとおりであり、本発明の実施の形態は補強材の改良であるため、補強材について詳述し、その余の構成は背景技術の項で述べた構成を援用する。 Hereinafter, a passenger conveyor according to an embodiment of the present invention will be described with reference to the drawings. The schematic configuration of the passenger conveyor is as described in the section of the background art, and since the embodiment of the present invention is an improvement of the reinforcing material, the reinforcing material will be described in detail. The configuration described in the section is used.

図４〜図８は第１の実施の形態を示す。 4 to 8 show a first embodiment.

図４〜図８において、１５は補強材を示し、該補強材１５は、図６に示すように、上部支え１５ａ、中間支持部１５ｂ及び下部支え１５ｃからなる断面コの字状の鋼材にて構成される。そして、図４に示すように、上部支え１５ａは乗降板１２の天板１２ａの下面側に取り付けられており、下部支え１５ｃは、図３に示す支承枠４のＬ字パネル４ｂの底面４ｂ’に載置されることにより、乗降板１２は支承枠４により支持される。具体的には、乗降板１２は、その天板１２ａの下面側に取り付けられた補強材１５を介して支承枠４のＬ字パネル４ｂの底部４ｂ’’によって支持される。また、この下部支え１５ｃの端部１５ｃ’は、上部支え１５ａより長く、乗降板１２の天板１２ａの踏段側の端縁１２ａ’まで延長した長さを有しており、乗降板１２の開閉作業時に発生する天板１２ａの端縁１２ａ’と支承枠４との接触を防ぐ役目を果たす。 4 to 8, reference numeral 15 denotes a reinforcing material. As shown in FIG. 6, the reinforcing material 15 is a steel material having a U-shaped cross section including an upper support 15a, an intermediate support 15b, and a lower support 15c. Composed. As shown in FIG. 4, the upper support 15a is attached to the lower surface side of the top plate 12a of the board 12 and the lower support 15c is a bottom surface 4b 'of the L-shaped panel 4b of the support frame 4 shown in FIG. The board 12 is supported by the support frame 4. Specifically, the boarding / alighting plate 12 is supported by the bottom portion 4b '' of the L-shaped panel 4b of the support frame 4 via a reinforcing member 15 attached to the lower surface side of the top plate 12a. Further, the end portion 15c ′ of the lower support 15c is longer than the upper support 15a and has a length extending to the step edge 12a ′ of the top plate 12a of the boarding plate 12 so that the boarding plate 12 can be opened and closed. It plays the role which prevents the contact with edge 12a 'of the top plate 12a and the support frame 4 which generate | occur | produces at the time of work.

乗降板１２を開閉する際には、乗降板１２の踏段側を支点として乗降板１２の乗り場側を持ち上げる。このとき、図５に示すように、下部支え１５ｃの端部１５ｃ’が支点となり、乗降板１２端部と支承枠４が接触しない。すなわち、下部支え１５ｃを乗降板１２の天板１２ａの踏段側の端縁１２ａ’まで延長した長さに形成したことによって、図７に示す乗降板１２を持ち上げていない状態から、図８に示す乗降板の乗り場側を持ち上げた状態まで傾斜していく過程においては、補強材１５の下部支え１５ｃの端部１５ｃ’が支承枠４のＬ字パネル４ｂの底面４ｂ’と接触し、この接触点が支点となって乗降板１２が持ち上がっていき、図８に示す傾斜角θ１の位置で天板１２ａの端縁１２ａ’が支承枠４のＬ字パネル４ｂの頂部４ｂ’’と接触することになる。この傾斜角θ１は、下部支え１５ｃを乗降板１２の天板１２ａの踏段側の端縁１２ａ’まで延長した長さに形成したことにより、図２８に示す従来の乗降板１０２における傾斜角αより大きく、乗降板１２を取り外すために乗降板１２の乗り場側を持ち上げるには十分な角度である。したがって、下部支え１５ｃを乗降板１２の天板１２ａの踏段側の端縁１２ａ’まで延長した長さに形成したことにより、天板１２ａの端縁１２ａ’が支承枠４のＬ字パネル４ｂの頂部４ｂ’’と接触するまでに乗降板１２を取り外すことが可能となる。 When opening and closing the board 12, the platform side of the board 12 is lifted with the step side of the board 12 as a fulcrum. At this time, as shown in FIG. 5, the end 15c 'of the lower support 15c serves as a fulcrum, and the end of the board 12 and the support frame 4 do not contact each other. That is, since the lower support 15c is formed to have a length that extends to the step edge 12a 'of the top plate 12a of the board 12 as shown in FIG. 8, the board 12 shown in FIG. In the process of tilting the boarding side of the boarding board to the lifted state, the end portion 15c ′ of the lower support 15c of the reinforcing member 15 contacts the bottom surface 4b ′ of the L-shaped panel 4b of the support frame 4, and this contact point The board 12 is lifted up as a fulcrum, and the edge 12a ′ of the top 12a contacts the top 4b ″ of the L-shaped panel 4b of the support frame 4 at the position of the inclination angle θ1 shown in FIG. Become. This inclination angle θ1 is formed by extending the lower support 15c to the step edge 12a ′ of the top plate 12a of the board 12 so that the inclination angle α in the conventional board 102 shown in FIG. The angle is large enough to lift the landing side of the board 12 to remove the board 12. Therefore, the lower support 15c is formed to have a length that extends to the step edge 12a ′ of the top plate 12a of the board 12 so that the edge 12a ′ of the top plate 12a can be connected to the L-shaped panel 4b of the support frame 4. The board 12 can be removed before it comes into contact with the top 4b ''.

このように、乗降板１２の開閉作業時の支点が補強材１５の下部支え１５ｃの端部１５ｃ’である状態で乗降板１２を取り外すことができ、天板１２ａの端縁１２ａ’が支点になるところまで乗降板１２を傾斜させる必要がない。したがって、天板１２ａの端縁１２ａ’と支承枠４との接触がなくなり、そのため乗降板天板の端縁１２ａ’に亀裂や曲がりによる歪みが発生しないので、乗降板１２が損傷したり、乗降板天板表面の意匠性が損なわれるおそれがない。 Thus, the boarding board 12 can be removed in a state where the fulcrum during the opening / closing operation of the boarding board 12 is the end 15c ′ of the lower support 15c of the reinforcing member 15, and the edge 12a ′ of the top board 12a serves as the fulcrum. It is not necessary to incline the boarding board 12 to a certain point. Therefore, the contact between the edge 12a ′ of the top plate 12a and the support frame 4 is eliminated, and therefore, the edge 12a ′ of the board 12 is not damaged by cracks or bends. There is no possibility that the design of the surface of the plate top plate is impaired.

図９〜図１１は第２の実施の形態を示す。 9 to 11 show a second embodiment.

第２の実施の形態は、第１の実施の形態における下部支え１５ｃの長さを乗降板１２の垂直方向投影面の端部よりも長く延出したものである。すなわち、図９に示す補強材２５は、上部支え２５ａ、中間支持部２５ｂ及び下部支え２５ｃからなる断面コの字状の鋼材にて構成される。図１０に示すように、上部支え２５ａは乗降板２２の天板２２ａの下面側に取り付けられており、下部支え２５ｃは支承枠４のＬ字パネル４ｂの底面４ｂ’に載置されることにより、乗降板２２は支承枠４により支持される。具体的には、乗降板２２は、その天板２２ａの下面側に取り付けられた補強材２５を介して支承枠４のＬ字パネル４ｂの底部４ｂ’’によって支持される。 In the second embodiment, the length of the lower support 15 c in the first embodiment is extended longer than the end of the vertical projection surface of the boarding / alighting plate 12. That is, the reinforcing member 25 shown in FIG. 9 is formed of a steel material having a U-shaped cross section including an upper support 25a, an intermediate support portion 25b, and a lower support 25c. As shown in FIG. 10, the upper support 25 a is attached to the lower surface side of the top plate 22 a of the boarding plate 22, and the lower support 25 c is placed on the bottom surface 4 b ′ of the L-shaped panel 4 b of the support frame 4. The boarding / alighting plate 22 is supported by the support frame 4. Specifically, the boarding / alighting plate 22 is supported by the bottom portion 4b '' of the L-shaped panel 4b of the support frame 4 via a reinforcing member 25 attached to the lower surface side of the top plate 22a.

乗降板２２を開閉する際には、乗降板２２の踏段側を支点として乗降板２２の乗り場側を持ち上げる。このとき、下部支え２５ｃの端部２５ｃ’が支点となり、乗降板２２端部と支承枠４が接触しない。すなわち、下部支え２５ｃを乗降板２２の垂直方向投影面の端部よりも長く形成したことによって、図１０に示す乗降板２２を持ち上げていない状態から、図１１に示す乗降板の乗り場側を持ち上げた状態まで傾斜していく過程においては、補強材２５の下部支え２５ｃの端部２５ｃ’が支承枠４のＬ字パネル４ｂの底面４ｂ’と接触して支点となって乗降板２２が持ち上がっていき、図１１に示す傾斜角θ２の位置で天板２２ａの端縁２２ａ’が支承枠４のＬ字パネル４ｂの頂部４ｂ’’と接触することになる。この傾斜角θ２は、下部支え２５ｃを乗降板２２の垂直方向投影面の端部よりも長く形成したことにより、図２８に示す従来の乗降板１０２における傾斜角αより大きく、また第１の実施の形態における傾斜角θ１よりも急傾斜となり、乗降板２２を取り外すために乗降板２２の乗り場側を持ち上げるには十分な角度である。したがって、下部支え２５ｃを乗降板２２の垂直方向投影面の端部よりも長く形成したことにより、天板２２ａの端縁２２ａ’が支承枠４のＬ字パネル４ｂの頂部４ｂ’’と接触するまでに乗降板２２を取り外すことが可能となる。 When opening and closing the boarding board 22, the landing side of the boarding board 22 is lifted with the step side of the boarding board 22 as a fulcrum. At this time, the end 25c 'of the lower support 25c serves as a fulcrum, and the end of the board 22 and the support frame 4 do not contact each other. That is, since the lower support 25c is formed longer than the end of the vertical projection surface of the boarding / alighting plate 22, the boarding side of the boarding / alighting plate shown in FIG. 11 is lifted from the state where the boarding / alighting plate 22 shown in FIG. In the process of inclining to the raised state, the end portion 25c ′ of the lower support 25c of the reinforcing member 25 comes into contact with the bottom surface 4b ′ of the L-shaped panel 4b of the support frame 4, and the boarding plate 22 is lifted as a fulcrum. Then, the edge 22a ′ of the top plate 22a comes into contact with the top 4b ″ of the L-shaped panel 4b of the support frame 4 at the position of the inclination angle θ2 shown in FIG. This inclination angle θ2 is larger than the inclination angle α in the conventional boarding board 102 shown in FIG. 28 by forming the lower support 25c longer than the end of the vertical projection surface of the boarding board 22 and the first embodiment. In this embodiment, the angle is steeper than the inclination angle θ1 and is sufficient to lift the boarding side of the boarding board 22 to remove the boarding board 22. Therefore, the lower support 25c is formed longer than the end of the vertical projection surface of the boarding / alighting plate 22, so that the edge 22a 'of the top plate 22a contacts the top 4b' 'of the L-shaped panel 4b of the support frame 4. It becomes possible to remove the boarding board 22 by the time.

このように、乗降板２２の開閉作業時の支点が補強材２５の下部支え２５ｃの端部２５ｃ’である状態で乗降板２２を取り外すことができ、天板２２ａの端縁２２ａ’が支点になるところまで乗降板２２を傾斜させる必要がない。したがって、天板２２ａの端縁２２ａ’と支承枠４との接触がなくなり、このため乗降板天板の端縁２２ａ’に亀裂や曲がりによる歪みが発生しないので、乗降板２２が損傷したり、乗降板天板表面の意匠性が損なわれるおそれがない。 Thus, the boarding board 22 can be removed in a state where the fulcrum during the opening / closing operation of the boarding board 22 is the end 25c ′ of the lower support 25c of the reinforcing member 25, and the edge 22a ′ of the top board 22a serves as the fulcrum. It is not necessary to incline the boarding board 22 to a certain point. Therefore, there is no contact between the edge 22a 'of the top plate 22a and the support frame 4, and therefore no distortion due to cracks or bending occurs at the edge 22a' of the boarding plate, so that the boarding plate 22 is damaged, There is no possibility that the design of the surface of the boarding board is impaired.

また、下部支えの端部を乗降板の垂直方向投影面より短くすればするほど、乗降板の傾斜角が緩やかになっていくため、乗降板天板の端縁と支承枠が接触する可能性が出てくるが、本実施の形態においては、下部支え２５ｃの端部２５ｃ’を乗降板２２の垂直方向投影面より長くしているので、天板２２ａの端縁２２ａ’と支承枠４との接触がさらになくなる。したがって、乗降板２２と支承枠４との接触をより確実になくすことができるので、乗降板天板の端縁２２ａ’に亀裂や曲がりによる歪みがより確実に発生しない。 In addition, as the end of the lower support is made shorter than the vertical projection plane of the board, the inclination angle of the board becomes gentler, so the edge of the board top plate and the support frame may come into contact with each other However, in the present embodiment, the end portion 25c ′ of the lower support 25c is made longer than the vertical projection surface of the boarding plate 22, so that the end edge 22a ′ of the top plate 22a, the support frame 4 and There will be no further contact. Therefore, since the contact between the boarding / alighting plate 22 and the support frame 4 can be more reliably eliminated, distortion due to a crack or a bend does not occur more reliably at the edge 22a 'of the boarding / alighting plate top plate.

図１２〜図１５は第３の実施の形態を示す。 12 to 15 show a third embodiment.

第３の実施の形態は、第１の実施の形態における下部支え１５ｃの端部１５ｃ’に曲げ加工を加えたものである。すなわち、図１２に示す補強材３５は、上部支え３５ａ、中間支持部３５ｂ及び下部支え３５ｃからなる断面コの字状の鋼材にて構成される。図１３に示すように、上部支え３５ａは乗降板３２の天板３２ａの下面側に取り付けられており、下部支え３５ｃは支承枠４のＬ字パネル４ｂの底面４ｂ’に載置されることにより、乗降板３２は支承枠４により支持される。具体的には、乗降板３２は、その天板３２ａの下面側に取り付けられた補強材３５を介して支承枠４のＬ字パネル４ｂの底部４ｂ’’によって支持される。 In the third embodiment, the end portion 15c 'of the lower support 15c in the first embodiment is bent. That is, the reinforcing member 35 shown in FIG. 12 is made of a U-shaped steel material having an upper support 35a, an intermediate support part 35b, and a lower support 35c. As shown in FIG. 13, the upper support 35 a is attached to the lower surface side of the top plate 32 a of the passenger board 32, and the lower support 35 c is placed on the bottom surface 4 b ′ of the L-shaped panel 4 b of the support frame 4. The boarding / alighting plate 32 is supported by the support frame 4. Specifically, the boarding / alighting plate 32 is supported by the bottom portion 4b '' of the L-shaped panel 4b of the support frame 4 via a reinforcing member 35 attached to the lower surface side of the top plate 32a.

乗降板３２を開閉する際には、乗降板３２の踏段側を支点として乗降板３２の乗り場側を持ち上げる。このとき、下部支え３５ｃの端部３５ｃ’が支点となり、乗降板３２端部と支承枠４が接触しない。すなわち、下部支え３５ｃを乗降板３２の天板３２ａの踏段側の端縁３２ａ’まで延長した長さに形成したことによって、図１３に示す乗降板３２を持ち上げていない状態から、図１４に示す乗降板の乗り場側を持ち上げた状態まで傾斜していく過程においては、補強材３５の下部支え３５ｃの端部３５ｃ’が支承枠４のＬ字パネル４ｂの底面４ｂ’と接触し、この接触点が支点となって乗降板３２が持ち上がっていき、図１４に示す傾斜角θ３の位置で天板３２ａの端縁３２ａ’が支承枠４のＬ字パネル４ｂの頂部４ｂ’’と接触することになる。この傾斜角θ３は、下部支え３５ｃを乗降板３２の天板３２ａの踏段側の端縁３２ａ’まで延長した長さに形成したことにより、図２８に示す従来の乗降板１０２における傾斜角αより大きく、乗降板３２を取り外すために乗降板３２の乗り場側を持ち上げるには十分な角度である。したがって、下部支え３５ｃを乗降板３２の天板３２ａの踏段側の端縁３２ａ’まで延長した長さに形成したことにより、天板３２ａの端縁３２ａ’が支承枠４のＬ字パネル４ｂの頂部４ｂ’’と接触するまでに乗降板３２を取り外すことが可能となる。 When opening and closing the boarding board 32, the platform side of the boarding board 32 is lifted with the step side of the boarding board 32 as a fulcrum. At this time, the end portion 35c 'of the lower support 35c serves as a fulcrum, and the end portion of the boarding / exiting plate 32 and the support frame 4 do not contact each other. That is, since the lower support 35c is formed to have a length that extends to the step edge 32a 'of the top plate 32a of the board 32, the board 32 shown in FIG. 13 is not lifted, as shown in FIG. In the process of tilting the boarding side of the boarding board to the lifted state, the end portion 35c ′ of the lower support 35c of the reinforcing member 35 comes into contact with the bottom surface 4b ′ of the L-shaped panel 4b of the support frame 4, and this contact point The board 32 is lifted up as a fulcrum, and the edge 32a ′ of the top plate 32a comes into contact with the top 4b ″ of the L-shaped panel 4b of the support frame 4 at the position of the inclination angle θ3 shown in FIG. Become. This inclination angle θ3 is formed by extending the lower support 35c to the step edge 32a ′ of the top plate 32a of the board 32, so that the inclination angle α in the conventional board 102 shown in FIG. The angle is large enough to lift the landing side of the boarding board 32 in order to remove the boarding board 32. Therefore, the lower support 35c is formed to have a length that extends to the step edge 32a 'of the top plate 32a of the board 32, so that the edge 32a' of the top plate 32a is formed on the L-shaped panel 4b of the support frame 4. It is possible to remove the boarding / alighting plate 32 before it comes into contact with the top 4b ″.

このように、乗降板３２の開閉作業時の支点が補強材３５の下部支え３５ｃの端部３５ｃ’である状態で乗降板３２を取り外すことができ、天板３２ａの端縁３２ａ’が支点になるところまで乗降板３２を傾斜させる必要がない。したがって、天板３２ａの端縁３２ａ’と支承枠４との接触がなくなり、そのため乗降板天板の端縁３２ａ’に亀裂や曲がりによる歪みが発生しないので、乗降板３２が損傷したり、乗降板天板表面の意匠性が損なわれるおそれがない。 Thus, the boarding / alighting plate 32 can be removed in a state where the fulcrum during the opening / closing operation of the boarding / alighting plate 32 is the end 35c ′ of the lower support 35c of the reinforcing member 35, and the edge 32a ′ of the top plate 32a serves as a fulcrum. There is no need to incline the board 32. Accordingly, there is no contact between the edge 32a 'of the top plate 32a and the support frame 4, so that the edge 32a' of the boarding / alighting plate does not undergo distortion due to cracks or bends. There is no possibility that the design of the surface of the plate top plate is impaired.

また、補強材３５の下部支え３５ｃの端部３５ｃ’を曲げ加工により湾曲形状としたので、乗降板３２を開閉する際に、乗降板３２の乗り場側を持ち上げて傾斜した状態で踏段側又は乗り場側にスライドさせる作業が、曲げ加工を施さない場合よりも容易となる利点がある。 Further, since the end portion 35c ′ of the lower support 35c of the reinforcing member 35 is bent into a curved shape by bending, when the boarding plate 32 is opened and closed, the platform side of the boarding plate 32 is lifted and the step side or platform is tilted. There is an advantage that the work of sliding to the side is easier than when bending is not performed.

図１５〜図１７は第４の実施の形態を示す。 15 to 17 show a fourth embodiment.

第４の実施の形態は、第３の実施の形態における下部支え３５ｃの曲げ加工を施した端部３５ｃ’に摺動部を、例えば接着剤等で取り付けたものである。すなわち、図１５に示す補強材４５は、第３の実施の形態において述べた構成を全て援用し、かつ、符号は同一符号を付す。 In the fourth embodiment, a sliding portion is attached, for example, with an adhesive or the like, to an end portion 35c 'where the lower support 35c is bent in the third embodiment. That is, the reinforcing material 45 shown in FIG. 15 uses all the configurations described in the third embodiment, and the same reference numerals are given.

第４の実施の形態においては、図１５〜図１７に示すように、補強材４５の下部支え３５ｃの湾曲した端部３５ｃ’の下面側、すなわち支承枠４のＬ字パネル４ｂの下面４ｂ’と接触する箇所に摺動部４５ｄを設ける。摺動部４５ｄには、自己潤滑性に優れた低摩擦で低摩耗の素材を接着剤使用などの接着方法にて接着する。素材としては、金属系やセラミックス系のものを使用してもよく、また高熱になることはないので、樹脂系のものを使用してもよい。 In the fourth embodiment, as shown in FIGS. 15 to 17, the lower surface side of the curved end portion 35 c ′ of the lower support 35 c of the reinforcing member 45, that is, the lower surface 4 b ′ of the L-shaped panel 4 b of the support frame 4. The sliding part 45d is provided in the place which contacts with. A low friction and low wear material excellent in self-lubricity is bonded to the sliding portion 45d by an adhesive method such as using an adhesive. As the material, a metal-based or ceramic-based material may be used, and a resin-based material may be used because it does not become hot.

このように、本実施の形態においては、補強材４５に、支承枠４と接触する下部支え３５ｃの端部３５ｃ’下面に摺動部４５ｄを取付けたので、下部支え３５ｃの端部３５ｃ’と支承枠４との間の摩擦を減らすことができる。そのため、乗降板４２の支承枠４上の移動が容易になる。したがって、上記第３の実施の形態における作用効果に加え、乗降板４２の開閉作業時に行うスライド作業がより容易に行える利点がある。 Thus, in the present embodiment, since the sliding portion 45d is attached to the lower surface of the end portion 35c ′ of the lower support 35c that contacts the support frame 4 in the reinforcing member 45, the end portion 35c ′ of the lower support 35c and Friction with the support frame 4 can be reduced. Therefore, the movement on the support frame 4 of the boarding board 42 becomes easy. Therefore, in addition to the operational effects of the third embodiment, there is an advantage that the sliding work performed during the opening / closing work of the boarding / alighting plate 42 can be performed more easily.

図１８〜図２０は第５の実施の形態を示す。 18 to 20 show a fifth embodiment.

第５の実施の形態は、第１の実施の形態における下部支え１５ｃの端部１５ｃ’にローラ５５ｆを取り付けたものである。すなわち、図１８に示す補強材５５は、上部支え５５ａ、中間支持部５５ｂ及び下部支え５５ｃからなる断面コの字状の鋼材にて構成される。図１９に示すように、上部支え５５ａは乗降板５２の天板５２ａの下面側に取り付けられており、下部支え５５ｃは支承枠４のＬ字パネル４ｂの底面４ｂ’に載置されることにより、乗降板５２は支承枠４により支持される。具体的には、乗降板５２は、その天板５２ａの下面側に取り付けられた補強材５５を介して支承枠４のＬ字パネル４ｂの底部４ｂ’’によって支持される。そして、下部支え５５ｃの端部５５ｃ’に取り付けたローラ５５ｆは、その回転軸が踏段方向に対して直交する方向としており、支承枠４のＬ字パネル４ｂの底面４ｂ’上を転動可能に構成されている。なお、ローラ５５ｆは本実施の形態のものに限られず、踏段方向へ転動可能なものであればどのような構成のものでもよい。 In the fifth embodiment, a roller 55f is attached to the end portion 15c 'of the lower support 15c in the first embodiment. That is, the reinforcing member 55 shown in FIG. 18 is formed of a steel material having a U-shaped cross section including an upper support 55a, an intermediate support part 55b, and a lower support 55c. As shown in FIG. 19, the upper support 55a is attached to the lower surface side of the top plate 52a of the passenger board 52, and the lower support 55c is placed on the bottom surface 4b 'of the L-shaped panel 4b of the support frame 4. The boarding / alighting plate 52 is supported by the support frame 4. Specifically, the boarding / alighting plate 52 is supported by the bottom portion 4b '' of the L-shaped panel 4b of the support frame 4 via a reinforcing material 55 attached to the lower surface side of the top plate 52a. The roller 55f attached to the end 55c ′ of the lower support 55c has a rotation axis that is orthogonal to the step direction, and can roll on the bottom surface 4b ′ of the L-shaped panel 4b of the support frame 4. It is configured. The roller 55f is not limited to the one in this embodiment, and may have any configuration as long as it can roll in the step direction.

乗降板５２を開閉する際には、乗降板５２の踏段側を支点として乗降板５２の乗り場側を持ち上げる。このとき、下部支え５５ｃの端部５５ｃ’に取り付けたローラ５５ｆの下面が支点となり、乗降板５２端部と支承枠４が接触しない。すなわち、下部支え５５ｃを形成したことによって、図１９に示す乗降板５２を持ち上げていない状態から、図２０に示す乗降板の乗り場側を持ち上げた状態まで傾斜していく過程においては、補強材５５の下部支え５５ｃの端部５５ｃ’に取り付けたローラ５５ｆが支承枠４のＬ字パネル４ｂの底面４ｂ’と接触し、この接触点が支点となって乗降板５２が持ち上がっていき、図２０に示す傾斜角θ５の位置で天板５２ａの端縁５２ａ’が支承枠４のＬ字パネル４ｂの頂部４ｂ’’と接触することになる。この傾斜角θ５は、下部支え５５ｃを乗降板５２の天板５２ａの踏段側の端縁５２ａ’まで延長した長さに形成したことにより、図２８に示す従来の乗降板１０２における傾斜角αより大きく、ローラ５５ｆを取り付けたことにより第１の実施の形態における傾斜角θ１より若干緩やかになるが、乗降板５２を取り外すために乗降板５２の乗り場側を持ち上げるには十分な角度である。したがって、下部支え５５ｃを乗降板５２の天板５２ａの踏段側の端縁５２ａ’まで延長した長さに形成したことにより、天板５２ａの端縁５２ａ’が支承枠４のＬ字パネル４ｂの頂部４ｂ’’と接触するまでに乗降板５２を取り外すことが可能となる。 When opening and closing the boarding board 52, the landing side of the boarding board 52 is lifted with the step side of the boarding board 52 as a fulcrum. At this time, the lower surface of the roller 55f attached to the end portion 55c 'of the lower support 55c serves as a fulcrum, and the end portion of the passenger board 52 and the support frame 4 do not contact each other. That is, by forming the lower support 55c, in the process of inclining from the state where the boarding board 52 shown in FIG. 19 is not lifted to the state where the boarding side of the boarding board shown in FIG. The roller 55f attached to the end portion 55c 'of the lower support 55c of the lower portion of the lower support 55c comes into contact with the bottom surface 4b' of the L-shaped panel 4b of the support frame 4, and the board 52 is lifted with this contact point as a fulcrum. The edge 52a ′ of the top plate 52a comes into contact with the top 4b ″ of the L-shaped panel 4b of the support frame 4 at the position of the inclination angle θ5 shown. This inclination angle θ5 is formed by extending the lower support 55c to the step edge 52a ′ of the top plate 52a of the board 52, so that the inclination angle α in the conventional board 102 shown in FIG. Although it is large and becomes slightly gentler than the inclination angle θ1 in the first embodiment by attaching the roller 55f, it is a sufficient angle to lift the landing side of the boarding board 52 in order to remove the boarding board 52. Therefore, the lower support 55c is formed to have a length that extends to the step edge 52a 'of the top plate 52a of the board 52, so that the end edge 52a' of the top plate 52a is formed on the L-shaped panel 4b of the support frame 4. It is possible to remove the boarding / alighting plate 52 before it comes into contact with the top 4b ″.

このように、乗降板５２の開閉作業時の支点が補強材５５の下部支え５５ｃの端部５５ｃ’に取り付けたローラ５５ｆである状態で乗降板５２を取り外すことができ、天板５２ａの端縁５２ａ’が支点になるところまで乗降板５２を傾斜させる必要がない。したがって、天板５２ａの端縁５２ａ’と支承枠４との接触がなくなり、このため乗降板天板の端縁５２ａ’に亀裂や曲がりによる歪みが発生しないので、乗降板５２が損傷したり、乗降板天板表面の意匠性が損なわれるおそれがない。 Thus, the boarding board 52 can be removed in a state where the fulcrum during the opening / closing operation of the boarding board 52 is the roller 55f attached to the end 55c 'of the lower support 55c of the reinforcing member 55, and the edge of the top board 52a It is not necessary to incline the boarding / alighting plate 52 to the point where 52a ′ becomes a fulcrum. Therefore, the contact between the end edge 52a ′ of the top plate 52a and the support frame 4 is eliminated, and therefore, the end edge 52a ′ of the boarding / alighting plate does not generate distortion due to cracks or bending. There is no possibility that the design of the surface of the boarding board is impaired.

また、補強材５５の下部支え５５ｃの端部５５ｃ’に、支承枠４上を転動できるローラ５５ｆを取り付けているので、乗降板５２を開閉する際に、乗降板５２の乗り場側を持ち上げて傾斜した状態で踏段側又は乗り場側にスライドさせる作業が、ローラ５５ｆを取り付けていない場合よりも容易となる利点がある。また、同時に支承枠４と下部支え５５ｃとの接触を抑えることができる利点がある。 Further, since the roller 55f that can roll on the support frame 4 is attached to the end 55c ′ of the lower support 55c of the reinforcing member 55, the landing side of the board 52 is lifted when the board 52 is opened and closed. There is an advantage that the work of sliding to the step side or the landing side in an inclined state is easier than when the roller 55f is not attached. Moreover, there is an advantage that contact between the support frame 4 and the lower support 55c can be suppressed at the same time.
