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 the edge on the footstep side of the getting-on and getting-off plate does 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 15d is added to a level difference prevention metal fitting 15, and an edge 12a' on a footstep side of a getting-on and getting-off plate 12 does not come into contact with a top of a support frame bottom surface 4b below the same when performing opening/closing work of the getting-on and getting-off plate 12 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.

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、図２５〜図２７に示すように、乗降板天板の下面に断面コの字型の補強材２ｂを溶接し、強度を増大させている。この補強材２ｂは、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。 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, as shown in FIGS. 25 to 27, a U-shaped reinforcing material 2b is welded to the lower surface of the boarding board to increase the strength. The reinforcing member 2b supports the boarding / alighting plate 2 by placing the bottom surface thereof on the bottom surface of the L-shaped panel 4b having the L-shape.

また、従来の乗降板１０２は、図２５〜図２７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１０５が取り付けられている。当該段差防止金具１０５は、図２５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おり、図２６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。 Further, as shown in FIGS. 25 to 27, the conventional boarding board 102 is provided with step prevention metal fittings 105 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. 25, the step prevention metal fitting 105 is attached at two places on the boarding board step side and at one place on the boarding board landing side, and as shown in FIG. 26, from the edge 102a ′ of the top board 102a. It is installed except between 10-20mm.

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２８及び図２９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３０に示す状態から図３１に示す状態までの傾斜角αの間は、補強材２ｂの下端２ｂ’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、段差防止金具１０５は、天板１０２ａの端縁１０２ａ’に段差防止金具１０５が達し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３２に示すように、補強材２ｂの下端２ｂ’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２９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 inspected, the opening / closing operation of the boarding / unloading plate 102 is performed. At that time, as shown in FIGS. 28 and 29, the landing side is lifted with the step side of the boarding / unloading plate 102 as a fulcrum. Become. For example, during the inclination angle α from the state shown in FIG. 30 to the state shown in FIG. 31, the conventional boarding / alighting plate 102 has a contact point between the lower end 2b ′ of the reinforcing member 2b and the bottom surface 4b ′ of the L-shaped panel 4b 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 / elevating plate 102 is lifted beyond the inclination angle α, the step prevention metal fitting 105 does not reach the edge 102a ′ of the top board 102a so that the step prevention metal fitting 105 does not reach the edge 102a ′ of the top board 102a. Contact between 102a ′ and the top 4b ″ of the L-shaped panel 4b cannot be avoided. As a result, as shown in FIG. 32, the lower end 2b ′ of the reinforcing member 2b is lifted, and the contact point between the top 4b ″ of the L-shaped panel 4b and the top plate 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、乗降板の踏段側の端縁が、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 boarding board is opened and closed, the step-side edge of the boarding board does not come into contact with the lower support frame, thereby raising the boarding board 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、前記の段差防止金具に下部支えを追加し、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。 When the passenger conveyor according to the embodiment of the present invention adds a lower support to the step-preventing bracket and lifts the boarding side of the boarding board to open and close the boarding board, the edge of the boarding side of the boarding board is The configuration is such that it does not come into 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段差防止金具の改良であるため、段差防止金具について詳述し、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 step prevention metal fitting, the step prevention metal fitting will be described in detail, and the rest of the configuration is the background. The configuration described in the technical section is used.

図４〜図９は第１の実施の形態を示す。 4 to 9 show a first embodiment.

図４〜図６に示す段差防止金具１５は、前面部１５ａ、上部支え１５ｂ、中間支持部１５ｃ及び下部支え１５ｄから構成される。上部支え１５ｂは、隣接する乗降板との間に段差が生じるのを防ぐためのものである。下部支え１５ｄは、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との接触を防ぐためのものである。中間支持部１５ｃは、上部支え１５ｂと下部支え１５ｄをつなぐためのものであり、前面部１５ａは、上部支え１５ｂから踏段側へ突出している。 4 to 6 includes a front surface part 15a, an upper support 15b, an intermediate support part 15c, and a lower support 15d. The upper support 15b is for preventing a level | step difference from arising between adjacent boarding / alighting boards. The lower support 15 d is for preventing contact between the edge 12 a ′ of the top plate 12 a and the support frame 4 that is generated when the boarding / alighting plate 12 is opened and closed. The intermediate support portion 15c is for connecting the upper support 15b and the lower support 15d, and the front surface portion 15a protrudes from the upper support 15b to the step side.

前記上部支え１５ｂは、乗降板１２の側面側端部に切り欠き１５ｅが設けられ、上部支え１５ｂ及び前面部１５ａが支承枠４と接触しない形状になっている。中間支持部１５ｃにも切り欠きが設けられており、中間支持部１５ｃの切り欠きにより段差防止金具１５を乗降板１２の補強材２ｂにボルト等を用いて固定できるようになっている。下部支え１５ｄが形成される箇所は乗降板１２を支える支承枠４の上方とし、これ以外の場所には下部支え１５ｄを形成する必要はない。 The upper support 15b is provided with a notch 15e at the side surface side end portion of the boarding / alighting plate 12, so that the upper support 15b and the front surface portion 15a do not come into contact with the support frame 4. The intermediate support portion 15c is also provided with a notch, and the step preventive bracket 15 can be fixed to the reinforcing member 2b of the boarding / alighting plate 12 with a bolt or the like by the notch of the intermediate support portion 15c. The place where the lower support 15d is formed is located above the support frame 4 that supports the board 12 and there is no need to form the lower support 15d in any other place.

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７に示すように、下部支え１５ｄの端部１５ｄ’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１５ｄを形成したことによって、図８に示す乗降板１２を持ち上げていない状態から、図９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、段差防止金具１５の下部支え１５ｄの端部１５ｄ’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９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１５ｄを形成したことにより、図３１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１５ｄを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. 7, the end 15d 'of the lower support 15d serves as a fulcrum, and the end of the board 12 and the support frame 4 do not contact each other. That is, in the process of tilting from the state where the boarding board 12 shown in FIG. 8 is not lifted to the state where the boarding side of the boarding board shown in FIG. 15 is in contact with the bottom surface 4b 'of the L-shaped panel 4b of the support frame 4, and the board 12 is lifted by using this contact point as a fulcrum, and the inclination angle θ1 shown in FIG. In this position, the edge 12a ′ of the top plate 12a comes into contact with the top 4b ″ of the L-shaped panel 4b of the support frame 4. This inclination angle θ1 is larger than the inclination angle α in the conventional boarding board 102 shown in FIG. 31 by forming the lower support 15d, and is sufficient to lift the landing side of the boarding board 12 in order to remove the boarding board 12 Is an angle. Therefore, by forming the lower support 15d, it is possible to remove the boarding / alighting plate 12 until the edge 12a 'of the top plate 12a comes into contact with the top 4b "of the L-shaped panel 4b of the support frame 4.

このように、乗降板１２の開閉作業時の支点が段差防止金具１５の下部支え１５ｄの端部１５ｄ’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 board 12 can be removed in a state where the fulcrum during the opening / closing operation of the board 12 is the end 15d 'of the lower support 15d of the step preventive bracket 15, and the edge 12a' of the top 12a is the fulcrum. It is not necessary to incline the boarding board 12 until it becomes. 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１０〜図１２は第２の実施の形態を示す。 10 to 12 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中間支持部１５ｃの高さを乗降板１２の補強材２ｂの高さより低くしたものである。すなわち、図１０〜図１２に示す段差防止金具２５は、前面部２５ａ、上部支え２５ｂ、中間支持部２５ｃ及び下部支え２５ｄから構成される。上部支え２５ｂは、隣接する乗降板との間に段差が生じるのを防ぐためのものである。下部支え２５ｄは、乗降板２２の開閉作業時に発生する天板２２ａの端縁２２ａ’と支承枠４との接触を防ぐためのものである。中間支持部２５ｃは、上部支え２５ｂと下部支え２５ｄをつなぐためのものであり、補強材２ｂの高さよりも低く形成されている。前面部２５ａは、上部支え２５ｂから踏段側へ突出している。 In the second embodiment, the height of the intermediate support portion 15c in the first embodiment is made lower than the height of the reinforcing member 2b of the boarding / alighting plate 12. That is, the level | step difference prevention metal fitting 25 shown in FIGS. 10-12 is comprised from the front part 25a, the upper support 25b, the intermediate | middle support part 25c, and the lower support 25d. The upper support 25b is for preventing a level | step difference from arising between adjacent boarding boards. The lower support 25 d is for preventing contact between the end edge 22 a ′ of the top plate 22 a and the support frame 4 that is generated when the boarding / alighting plate 22 is opened and closed. The intermediate support portion 25c is for connecting the upper support 25b and the lower support 25d, and is formed lower than the height of the reinforcing member 2b. The front part 25a protrudes from the upper support 25b to the step side.

前記上部支え２５ｂは、乗降板２２の側面側端部に切り欠き２５ｅが設けられ、上部支え２５ｂ及び前面部２５ａが支承枠４と接触しない形状になっている。中間支持部２５ｃにも切り欠きが設けられており、中間支持部２５ｃの切り欠きにより段差防止金具２５を乗降板２２の補強材２ｂにボルト等を用いて固定できるようになっている。下部支え２５ｄが形成される箇所は乗降板２２を支える支承枠４の上方とし、これ以外の場所には下部支え２５ｄを形成する必要はない。 The upper support 25 b is provided with a notch 25 e at the side surface side end portion of the boarding / alighting plate 22, so that the upper support 25 b and the front surface portion 25 a do not contact the support frame 4. The intermediate support portion 25c is also provided with a notch, and the step prevention metal fitting 25 can be fixed to the reinforcing member 2b of the boarding board 22 with a bolt or the like by the notch of the intermediate support portion 25c. The place where the lower support 25d is formed is located above the support frame 4 that supports the boarding board 22 and it is not necessary to form the lower support 25d in any other place.

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２５ｄの端部２５ｄ’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２５ｄを形成したことによって、図１１に示す乗降板２２を持ち上げていない状態から、図１２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、段差防止金具２５の下部支え２５ｄの端部２５ｄ’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２２が持ち上がっていき、図１２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２５ｄを形成したことにより、図３１に示す従来の乗降板１０２における傾斜角αより大きく、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２５ｄを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 25d 'of the lower support 25d serves as a fulcrum, and the end of the board 22 and the support frame 4 do not contact each other. That is, in the process of tilting from the state where the boarding board 22 shown in FIG. 11 is not lifted to the state where the boarding side of the boarding board shown in FIG. 25, the end portion 25d 'of the lower support 25d 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 with this contact point as a fulcrum, and the inclination angle θ2 shown in FIG. In this position, 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. The inclination angle θ2 is larger than the inclination angle α in the conventional boarding / alighting plate 102 shown in FIG. 31 due to the formation of the lower support 25d, and is slightly gentler than the inclination angle θ1 in the first embodiment. The angle is sufficient for lifting the landing side of the boarding board 22 to remove the board 22. Therefore, by forming the lower support 25d, it is possible to remove the boarding plate 22 until the end 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.

このように、乗降板２２の開閉作業時の支点が段差防止金具２５の下部支え２５ｄの端部２５ｄ’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、そ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 25d 'of the lower support 25d of the step preventive bracket 25, and the edge 22a' of the top board 22a is the fulcrum. It is not necessary to incline the boarding board 22 until it becomes. Therefore, the contact between the edge 22a ′ of the top plate 22a and the support frame 4 is eliminated, and therefore, the edge 22a ′ of the boarding / alighting plate does not undergo distortion due to cracks or bending, so that the boarding / alighting plate 22 may be damaged or There is no possibility that the design of the surface of the plate top plate is impaired.

また、乗降板２２の補強材２ｂは乗降材２２本体を支えるために取付けられているものである。本実施の形態においては、この乗降板２２を支えている補強材２ｂの高さよりも、段差防止金具２５の中間支持部２５ｃを短くしているので、乗降板２２の荷重を段差防止金具２５で受けなくてすむ利点がある。 Further, the reinforcing material 2b of the boarding / alighting plate 22 is attached to support the main body of the boarding / alighting material 22. In the present embodiment, the intermediate support portion 25c of the step prevention metal fitting 25 is made shorter than the height of the reinforcing member 2b supporting the boarding / alighting plate 22, so There is an advantage of not receiving it.

図１３〜図１５は第３の実施の形態を示す。 13 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１５ｄ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１３〜図１５に示す段差防止金具３５は、前面部３５ａ、上部支え３５ｂ、中間支持部３５ｃ及び下部支え３５ｄから構成される。上部支え３５ｂは、隣接する乗降板との間に段差が生じるのを防ぐためのものである。下部支え３５ｄは、乗降板３２の開閉作業時に発生する天板３２ａの端縁３２ａ’と支承枠４との接触を防ぐためのものであり、下部支え３５ｄの端部３５ｄ’は前面部３５ａよりも長く延出して形成されている。中間支持部３５ｃは、上部支え３５ｂと下部支え３５ｄをつなぐためのものであり、前面部３５ａは、上部支え３５ｂから踏段側へ突出している。 In the third embodiment, the length of the lower support 15d in the first embodiment is extended longer than the end portion of the vertical projection surface of the boarding / alighting plate 12. That is, the level | step difference prevention metal fitting 35 shown in FIGS. 13-15 is comprised from the front part 35a, the upper support 35b, the intermediate | middle support part 35c, and the lower support 35d. The upper support 35b is for preventing a level | step difference between adjacent boarding boards. The lower support 35d is for preventing contact between the end edge 32a 'of the top plate 32a and the support frame 4 that is generated when the boarding / alighting plate 32 is opened and closed. The end 35d' of the lower support 35d is formed from the front surface 35a. It is also formed to extend long. The intermediate support portion 35c is for connecting the upper support 35b and the lower support 35d, and the front surface portion 35a protrudes from the upper support 35b to the step side.

前記上部支え３５ｂは、乗降板３２の側面側端部に切り欠き３５ｅが設けられ、上部支え３５ｂ及び前面部３５ａが支承枠４と接触できない形状になっている。中間支持部３５ｃにも切り欠きが設けられており、中間支持部３５ｃの切り欠きにより段差防止金具３５を乗降板３２の補強材２ｂにボルト等を用いて固定できるようになっている。下部支え３５ｄが形成される箇所は乗降板３２を支える支承枠４の上方とし、これ以外の場所には下部支え３５ｄを形成する必要はない。 The upper support 35b is provided with a notch 35e at the end of the side surface of the board 32, so that the upper support 35b and the front surface 35a cannot come into contact with the support frame 4. The intermediate support portion 35c is also provided with a notch, and the step prevention metal fitting 35 can be fixed to the reinforcing member 2b of the boarding / alighting plate 32 with a bolt or the like by the notch of the intermediate support portion 35c. The place where the lower support 35d is formed is located above the support frame 4 that supports the boarding plate 32, and it is not necessary to form the lower support 35d in any other place.

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３５ｄの端部３５ｄ’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３５ｄを形成したことによって、図１４に示す乗降板３２を持ち上げていない状態から、図１５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、段差防止金具３５の下部支え３５ｄの端部３５ｄ’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３２が持ち上がっていき、図１５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３５ｄを形成したことにより、図３１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３５ｄを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 35d 'of the lower support 35d serves as a fulcrum, and the end portion of the passenger board 32 and the support frame 4 do not contact each other. That is, in the process of tilting from the state where the boarding board 32 shown in FIG. 14 is not lifted up to the state where the boarding side of the boarding board shown in FIG. The end portion 35d 'of the lower support 35d contacts the bottom surface 4b' of the L-shaped panel 4b of the support frame 4 to become a fulcrum, and the boarding / alighting plate 32 is lifted, and at the position of the inclination angle θ3 shown in FIG. The edge 32 a ′ of the plate 32 a comes into contact with the top 4 b ″ of the L-shaped panel 4 b of the support frame 4. Since the lower support 35d is formed, the inclination angle θ3 is larger than the inclination angle α in the conventional boarding / alighting plate 102 shown in FIG. 31, and is steeper than the inclination angle θ1 in the first embodiment. The angle is sufficient to lift the landing side of the boarding board 32 to remove 32. Therefore, by forming the lower support 35d, it is possible to remove the boarding / alighting plate 32 until 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.

このように、乗降板３２の開閉作業時の支点が段差防止金具３５の下部支え３５ｄの端部３５ｄ’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、こ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 35d 'of the lower support 35d of the step prevention metal fitting 35, and the edge 32a' of the top plate 32a is the fulcrum. It is not necessary to incline the boarding board 32 until it becomes. Therefore, there is no contact between the end edge 32a ′ of the top plate 32a and the support frame 4, and therefore the end edge 32a ′ of the top and bottom plate does not suffer from distortion due to cracks or bends. 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３５ｄの端部３５ｄ’を乗降板３２の垂直方向投影面より長くしているので、天板３２ａの端縁３２ａ’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３２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３２ａ’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 35d 'of the lower support 35d is made longer than the vertical projection surface of the board 32, so that the edge 32a' of the top plate 32a, the support frame 4 and There will be no further contact. Therefore, since the contact between the boarding / alighting plate 32 and the support frame 4 can be more reliably eliminated, the end edge 32a 'of the boarding / alighting plate top plate is more reliably prevented from being deformed by cracks or bending.

図１６〜図１８は第４の実施の形態を示す。 16 to 18 show a fourth embodiment.

第４の実施の形態は、第１の実施の形態における下部支え１５ｄの端部１５ｄ’に曲げ加工を加えたものである。すなわち、図１６〜図１８に示す段差防止金具４５は、前面部４５ａ、上部支え４５ｂ、中間支持部４５ｃ及び下部支え４５ｄから構成される。上部支え４５ｂは、隣接する乗降板との間に段差が生じるのを防ぐためのものである。下部支え４５ｄは、乗降板４２の開閉作業時に発生する天板４２ａの端縁４２ａ’と支承枠４との接触を防ぐためのものであり、下部支え４５ｄの端部４５ｄ’は上方向けに湾曲する曲げ加工を施した湾曲形状をなしている。中間支持部４５ｃは、上部支え４５ｂと下部支え４５ｄをつなぐためのものであり、前面部４５ａは、上部支え４５ｂから踏段側へ突出している。 In the fourth embodiment, the end portion 15d 'of the lower support 15d in the first embodiment is bent. That is, the level | step difference prevention metal fitting 45 shown in FIGS. 16-18 is comprised from the front part 45a, the upper support 45b, the intermediate | middle support part 45c, and the lower support 45d. The upper support 45b is for preventing a level | step difference between adjacent boarding boards. The lower support 45d is for preventing contact between the end edge 42a 'of the top plate 42a and the support frame 4 that is generated when the boarding / alighting plate 42 is opened / closed, and the end 45d' of the lower support 45d is curved upward. It has a curved shape that has been bent. The intermediate support portion 45c is for connecting the upper support 45b and the lower support 45d, and the front surface portion 45a protrudes from the upper support 45b to the step side.

前記上部支え４５ｂは、乗降板４２の側面側端部に切り欠き４５ｅが設けられ、上部支え４５ｂ及び前面部４５ａが支承枠４と接触しない形状になっている。中間支持部４５ｃにも切り欠きが設けられており、中間支持部４５ｃの切り欠きにより段差防止金具４５を乗降板４２の補強材２ｂにボルト等を用いて固定できるようになっている。下部支え４５ｄが形成される箇所は乗降板４２を支える支承枠４の上方とし、これ以外の場所には下部支え４５ｄを形成する必要はない。 The upper support 45b is provided with a notch 45e at the end of the side surface of the board 42, so that the upper support 45b and the front surface 45a do not come into contact with the support frame 4. The intermediate support portion 45c is also provided with a notch so that the step prevention metal fitting 45 can be fixed to the reinforcing member 2b of the boarding plate 42 with a bolt or the like by the notch of the intermediate support portion 45c. The portion where the lower support 45d is formed is located above the support frame 4 that supports the boarding plate 42, and it is not necessary to form the lower support 45d at other locations.

乗降板４２を開閉する際には、乗降板４２の踏段側を支点として乗降板４２の乗り場側を持ち上げる。このとき、下部支え４５ｄの端部４５ｄ’が支点となり、乗降板４２端部と支承枠４が接触しない。すなわち、下部支え４５ｄを形成したことによって、図１７に示す乗降板４２を持ち上げていない状態から、図１８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、段差防止金具４５の下部支え４５ｄの端部４５ｄ’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４２が持ち上がっていき、図１８に示す傾斜角θ４の位置で天板４２ａの端縁４２ａ’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θ４は、下部支え４５ｄを形成したことにより、図３１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４２を取り外すために乗降板４２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４５ｄを形成したことにより、天板４２ａの端縁４２ａ’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 42, the platform side of the boarding board 42 is lifted with the step side of the boarding board 42 as a fulcrum. At this time, the end 45d 'of the lower support 45d serves as a fulcrum, and the end of the board 42 and the support frame 4 do not contact each other. That is, in the process of tilting from the state where the boarding board 42 shown in FIG. 17 is not lifted to the state where the boarding side of the boarding board shown in FIG. An end portion 45d 'of the lower support 45d of 45 comes into contact with the bottom surface 4b' of the L-shaped panel 4b of the support frame 4, and the boarding plate 42 is lifted with this contact point as a fulcrum, and the inclination angle θ4 shown in FIG. In this position, the edge 42a 'of the top plate 42a comes into contact with the top 4b' 'of the L-shaped panel 4b of the support frame 4. The inclination angle θ4 is larger than the inclination angle α in the conventional boarding board 102 shown in FIG. 31 because the lower support 45d is formed, and is sufficient to lift the landing side of the boarding board 42 in order to remove the boarding board 42. Is an angle. Therefore, by forming the lower support 45d, it is possible to remove the boarding plate 22 until the end edge 42a 'of the top plate 42a comes into contact with the top 4b "of the L-shaped panel 4b of the support frame 4.

このように、乗降板４２の開閉作業時の支点が段差防止金具４５の下部支え４５ｄの端部４５ｄ’である状態で乗降板４２を取り外すことができ、天板４２ａの端縁４２ａ’が支点になるところまで乗降板４２を傾斜させる必要がない。したがって、天板４２ａの端縁４２ａ’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４２ａ’に亀裂や曲がりによる歪みが発生しないので、乗降板４２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 42 can be removed in a state where the fulcrum during the opening / closing operation of the boarding board 42 is the end 45d 'of the lower support 45d of the step prevention metal fitting 45, and the edge 42a' of the top board 42a is the fulcrum. It is not necessary to incline the boarding / alighting plate 42 to the point. Therefore, the contact between the end edge 42a 'of the top plate 42a and the support frame 4 is eliminated, so that the end edge 42a' of the boarding / alighting plate top plate is not distorted by cracks or bending. There is no possibility that the design of the surface of the plate top plate is impaired.

また、段差防止金具４５の下部支え４５ｄの端部４５ｄ’を曲げ加工により湾曲形状としたので、乗降板４２を開閉する際に、乗降板４２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。 In addition, since the end portion 45d ′ of the lower support 45d of the step-preventing metal fitting 45 is bent by bending, when the boarding plate 42 is opened and closed, the platform side of the boarding plate 42 is lifted and tilted with the step side or There is an advantage that the work of sliding to the landing side is easier than when bending is not performed.

図１９〜図２１は第５の実施の形態を示す。 19 to 21 show a fifth embodiment.

第５の実施の形態は、第４の実施の形態における下部支え４５ｄの曲げ加工を施した端部４５ｄ’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１９〜図２１に示す段差防止金具５５は、第４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 fifth embodiment, a sliding portion is attached, for example, with an adhesive or the like, to an end portion 45d 'where the lower support 45d is bent in the fourth embodiment. That is, the step prevention metal fitting 55 shown in FIGS. 19 to 21 uses all the configurations described in the fourth embodiment, and the same reference numerals are given.

第５の実施の形態においては、図１９〜図２１に示すように、段差防止金具５５の下部支え４５ｄの湾曲した端部４５ｄ’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５５ｆを設ける。摺動部５５ｆ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 fifth embodiment, as shown in FIGS. 19 to 21, the lower surface side of the curved end portion 45 d ′ of the lower support 45 d of the step prevention metal fitting 55, that is, the lower surface 4 b of the L-shaped panel 4 b of the support frame 4. A sliding portion 55f is provided at a position where it comes into contact with '. A low friction and low wear material excellent in self-lubricity is bonded to the sliding portion 55f 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、段差防止金具５５に、支承枠４と接触する下部支え４５ｄの端部４５ｄ’下面に摺動部５５ｆを取付けたので、下部支え４５ｄの端部４５ｄ’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５２の支承枠４上の移動が容易になる。したがって、上記第４の実施の形態における作用効果に加え、乗降板５２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。 As described above, in the present embodiment, since the sliding portion 55f is attached to the lower surface of the end portion 45d ′ of the lower support 45d that contacts the support frame 4 in the step prevention metal fitting 55, the end portion 45d ′ of the lower support 45d is attached. And the friction between the support frame 4 can be reduced. Therefore, the movement on the support frame 4 of the boarding / alighting board 52 becomes easy. Therefore, in addition to the function and effect of the fourth embodiment, there is an advantage that the sliding work performed when opening and closing the boarding board 52 can be performed more easily.

図２２〜図２４は第６の実施の形態を示す。 22 to 24 show a sixth embodiment.

第６の実施の形態は、第１の実施の形態における下部支え１５ｄの端部１５ｄ’にローラ６５ｇを取り付けたものである。すなわち、図２２〜図２４に示す段差防止金具６５は、前面部６５ａ、上部支え６５ｂ、中間支持部６５ｃ及び下部支え６５ｄから構成される。上部支え６５ｂは、隣接する乗降板との間に段差が生じるのを防ぐためのものである。下部支え６５ｄは、乗降板６２の開閉作業時に発生する天板６２ａの端縁６２ａ’と支承枠４との接触を防ぐためのものであり、下部支え６５ｄの端部６５ｄ’にはローラ６５ｇが取り付けられている。ローラ６５ｇ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６５ｇ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。中間支持部６５ｃは、上部支え６５ｂと下部支え６５ｄをつなぐためのものであり、前面部６５ａは、上部支え６５ｂから踏段側へ突出している。 In the sixth embodiment, a roller 65g is attached to the end portion 15d 'of the lower support 15d in the first embodiment. That is, the level | step difference prevention metal fitting 65 shown in FIGS. 22-24 is comprised from the front part 65a, the upper support 65b, the intermediate | middle support part 65c, and the lower support 65d. The upper support 65b is for preventing a level | step difference from producing between adjacent boarding / alighting boards. The lower support 65d is for preventing contact between the edge 62a 'of the top plate 62a and the support frame 4 that is generated when the boarding / exiting plate 62 is opened and closed. A roller 65g is provided on the end 65d' of the lower support 65d. It is attached. The roller 65g has a rotational axis that is perpendicular to the step direction, and is configured to roll on the bottom surface 4b 'of the L-shaped panel 4b of the support frame 4. The roller 65g is not limited to the one in this embodiment, and may have any configuration as long as it can roll in the step direction. The intermediate support portion 65c is for connecting the upper support 65b and the lower support 65d, and the front surface portion 65a protrudes from the upper support 65b to the step side.

前記上部支え６５ｂは、乗降板６２の側面側端部に切り欠き６５ｅが設けられ、上部支え６５ｂ及び前面部６５ａが支承枠４と接触しない形状になっている。中間支持部６５ｃにも切り欠きが設けられており、中間支持部６５ｃの切り欠きにより段差防止金具６５を乗降板６２の補強材２ｂにボルト等を用いて固定できるようになっている。下部支え６５ｄが形成される箇所は乗降板６２を支える支承枠４の上方とし、これ以外の場所には下部支え６５ｄを形成する必要はない。 The upper support 65 b is provided with a notch 65 e at the end of the side surface of the boarding / alighting plate 62, so that the upper support 65 b and the front surface 65 a do not come into contact with the support frame 4. The intermediate support portion 65c is also provided with a notch, and the step preventive metal fitting 65 can be fixed to the reinforcing member 2b of the boarding / alighting plate 62 with a bolt or the like by the notch of the intermediate support portion 65c. The place where the lower support 65d is formed is located above the support frame 4 that supports the passenger board 62, and it is not necessary to form the lower support 65d in any other place.

乗降板６２を開閉する際には、乗降板６２の踏段側を支点として乗降板６２の乗り場側を持ち上げる。このとき、下部支え６５ｄの端部６５ｄ’に取り付けたローラ６５ｇの下面が支点となり、乗降板６２端部と支承枠４が接触しない。すなわち、下部支え６５ｄを形成したことによって、図２３に示す乗降板６２を持ち上げていない状態から、図２４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、段差防止金具６５の下部支え６５ｄの端部６５ｄ’に取り付けたローラ６５ｇ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６２が持ち上がっていき、図２４に示す傾斜角θ６の位置で天板６２ａの端縁６２ａ’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θ６は、下部支え６５ｄを形成したことにより、図３１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６５ｇ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６２を取り外すために乗降板６２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６５ｄを形成したことにより、天板６２ａの端縁６２ａ’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６２を取り外すことが可能となる。 When opening and closing the boarding board 62, the platform side of the boarding board 62 is lifted with the step side of the boarding board 62 as a fulcrum. At this time, the lower surface of the roller 65g attached to the end portion 65d 'of the lower support 65d serves as a fulcrum, and the end portion of the passenger board 62 and the support frame 4 do not contact each other. That is, in the process of tilting from the state where the boarding board 62 shown in FIG. 23 is not lifted to the state where the boarding side of the boarding board shown in FIG. The roller 65g attached to the end portion 65d 'of the lower support 65d of the 65 comes into contact with the bottom surface 4b' of the L-shaped panel 4b of the support frame 4, and the boarding board 62 is lifted with this contact point as a fulcrum. The edge 62a ′ of the top plate 62a 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 θ6 shown in FIG. This inclination angle θ6 is larger than the inclination angle α in the conventional boarding / alighting plate 102 shown in FIG. 31 due to the formation of the lower support 65d, and is slightly larger than the inclination angle θ1 in the first embodiment by attaching the roller 65g. Although it becomes gentle, the angle is sufficient to lift the landing side of the boarding board 62 to remove the boarding board 62. Therefore, by forming the lower support 65d, it is possible to remove the passenger board 62 until the end edge 62a 'of the top plate 62a comes into contact with the top 4b' 'of the L-shaped panel 4b of the support frame 4.

このように、乗降板６２の開閉作業時の支点が段差防止金具６５の下部支え６５ｄの端部６５ｄ’に取り付けたローラ６５ｇである状態で乗降板６２を取り外すことができ、天板６２ａの端縁６２ａ’が支点になるところまで乗降板６２を傾斜させる必要がない。したがって、天板６２ａの端縁６２ａ’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６２ａ’に亀裂や曲がりによる歪みが発生しないので、乗降板６２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 62 can be removed in a state where the fulcrum during the opening / closing operation of the boarding board 62 is the roller 65g attached to the end portion 65d ′ of the lower support 65d of the step prevention metal fitting 65, and the end of the top board 62a can be removed. It is not necessary to incline the boarding / exiting plate 62 until the edge 62a ′ becomes a fulcrum. Therefore, the contact between the end edge 62a ′ of the top plate 62a and the support frame 4 is eliminated, and therefore, the end edge 62a ′ of the boarding / alighting plate top plate is not distorted by cracks or bending. There is no possibility that the design of the surface of the boarding board is impaired.

また、段差防止金具６５の下部支え６５ｄの端部６５ｄ’に、支承枠４上を転動できるローラ６５ｇを取り付けているので、乗降板６２を開閉する際に、乗降板６２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６５ｇ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６５ｄとの接触を抑えることができる利点がある。 Further, since the roller 65g that can roll on the support frame 4 is attached to the end portion 65d ′ of the lower support 65d of the step prevention metal fitting 65, when the boarding board 62 is opened and closed, the boarding side of the boarding board 62 is lifted. 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 65g is not attached. Moreover, there is an advantage that contact between the support frame 4 and the lower support 65d can be suppressed at the same time.

なお、本実施例はエスカレータについて説明したが、動く歩道に対しても適用できるものである。また、実施の形態は例示であり、発明の範囲は実施の形態に限られるものではない。 In addition, although the present Example demonstrated the escalator, it is applicable also to a moving sidewalk.
