Description

【０００１】
【発明の属する技術分野】
この発明は、踏み面の主枠上端側の縁部に設けられて長手が踏段の幅方向に沿って配置された合成樹脂製の上端側縁部櫛板を装備したエスカレーターの踏段に関する。
【０００２】
【従来の技術】
図４〜図７は、従来のエスカレーターの踏段を示す図で、図４はエスカレーターの主枠における踏段の設置状態を説明する斜視図、図５は図４のＡ−Ａ線断面を拡大して示す斜視図、図６は図４における踏段の上端側縁部櫛板の装着作業状況を説明する図５の右側面図、図７は図５における上端側縁部櫛板の破損状態を説明する図６相当図である。図において、１は踏段鎖で、傾斜して設置された主枠（図示しない）無端状に配置され、主枠の幅方向における両側にそれぞれ設けられている。
【０００３】
２は主枠に多数が隣接して配置された踏段、３は踏段２の基体、４は踏段軸で、基体３に設けられて踏段２の主枠の上端側寄りに配置され、両端が踏段２幅から突出して設けられてそれぞれ踏段鎖１に嵌合されて踏段２を踏段鎖１に連結する。これにより、多数の踏段２が踏段鎖１を介して無端状に連結される。５は踏段軸４に枢着されて主枠に設けられた駆動輪用レール（図示しない）を転動する駆動輪である。
【０００４】
６は踏段２の主枠の下端側寄りに枢着されて主枠に設けられた追従輪用レール（図示しない）を転動する追従輪である。７は桟で、踏段２の上面、すなわち踏み面を形成し、多数が互いに離れて踏段２の移動方向に沿って平行に設けられている。８は踏段２の主枠の下端側を構成するライザで、縦断面が円弧状に形成され表面に踏み面の桟７と対向する溝が設けられている。
【０００５】
９は上端側縁部櫛板で、踏段２の基体３の主枠上端側の縁部に設けられて長手が踏段２の幅方向に沿って設けられ複数個が直列に配置され、基板１０の上面に桟７に連続する複数の櫛歯片１１が形成され、また隣接した踏段２のライザ８に対向した基板１０の縁部にライザ８の溝に対向して突設された櫛歯１２が設けられている。
【０００６】
１３は締結具で、頭付きねじからなり上端側縁部櫛板９の長手の中心及び両端部寄りにそれぞれ設けられて基板１０に挿通されて基体３にねじ込まれて、上端側縁部櫛板９の基板１０を上方から踏段２の基体３に締結する。１４はスカートガードで、図示が省略してあるがエスカレーターの欄干下部を形成して設けられて、踏段２の幅方向の端面に僅かな空隙を形成して対面して配置されている。
【０００７】
従来のエスカレーターの踏段は上記のように構成され、多数の踏段２が踏段鎖１によって無端状に連続され、主枠内を循環運転される。そして、主枠の端部に形成された乗降口に櫛板（図示しない）が設けられて、踏段２が乗降口を移動するときに、踏段２の桟７、上端側縁部櫛板９の櫛歯片１１が乗降口の櫛板の下側を、櫛板に噛み合う状態で通過する。
【０００８】
また、踏段２が主枠を移動するときに、互いに隣接した踏段２の相互が上下方向に相対変位する箇所では、踏段２のライザ８の溝とこの溝に対向した他の踏段２に設けられた上端側縁部櫛板９の櫛歯１２が噛み合う状態で相対変位する。なお、上端側縁部櫛板９は踏段２の基体３に対して図６に示すように長手の中心及び両端寄りがそれぞれ締結具１３によって締結されている。
【０００９】
そして、上端側縁部櫛板９は注意色、すなわち黄色等に着色された合成樹脂によって製作されるのが一般的である。また、上端側縁部櫛板９は耐衝撃性の高いポリカーボネート樹脂等の成形品が使用され、保守作業における利便性のために踏段２の幅方向長さを複数に分割した長さに製作されて踏段２の基体３に装着される。このように構成されることによって、踏段２が乗降口を通過するときに、互いに隣接する踏段２相互の境界を明瞭化するために上端側縁部櫛板９が設けられている。
【００１０】
【発明が解決しようとする課題】
上記のような従来のエスカレーターの踏段では、上端側縁部櫛板９が基板１０の上側に複数の櫛歯片１１が形成された形状に射出成形される。このため、成形品の冷却後における上端側縁部櫛板９の自由形状が、基板１０の両端側の上面が上昇し基板１０の長手中心が下降した湾曲形状、すなわち図６に示すように湾曲した形状になる。これは上端側縁部櫛板９が櫛歯片１１と基板１６とからなる非対称形状をしているからである。そして、このように湾曲した形状の上端側縁部櫛板９を、弾性変形させて長手の中心及び両端寄りがそれぞれ締結具１３によって踏段２の基体３上面に締結されることにより直線形状に装着される。
【００１１】
このようにして装着された上端側縁部櫛板９に、踏段２の清掃作業時に強アルカリ剤や溶剤等を含む床クリーナ剤が使用されると、上端側縁部櫛板９に床クリーナ剤が付着して特に内部応力が高くなっている締結具１３の締結孔箇所にクレージング現象によるクラックが発生する場合がある。このときに上端側縁部櫛板９の長手中心の締結孔箇所が破断したときには、長手の両端寄りがそれぞれ締結具１３によって踏段２の基体３に押圧状態に締結されているので、上端側縁部櫛板９は自由形状に復帰して図７に示すように破断した長手中心が浮き上がる。
【００１２】
このため、長手中心が浮上した上端側縁部櫛板９が踏段２が乗降口を通過するときに、乗降口の櫛板に衝突して櫛板が破損する等の不具合の発生が懸念されるという問題点があった。なお、上端側縁部櫛板９の一方の長手端部寄りの締結具１３の締結孔箇所にクラックが発生して破断した場合にも、破断箇所において上端側縁部櫛板９が自由形状に復帰するため浮き上がって前述の不具合が発生することになる。
【００１３】
この発明は、かかる問題点を解消するためになされたものであり、踏段に締結された上端側縁部櫛板の締結箇所に破断が生じても、破断箇所に浮き上がりが発生しないエスカレーターの踏段を得ることを目的とする。
【００１４】
【課題を解決するための手段】
この発明に係るエスカレーターの踏段においては、多数が無端状に連結されて傾斜して設置された主枠中を循環運転される踏段、これらの踏段の上面に設けられて長手が運転方向に沿って配置されて、踏段の踏み面を形成する複数本の桟と、踏段の上面の主枠上端側の縁部に設けられて長手が踏段の幅方向に沿って配置されて、基板及びこの基板の上面に踏段の桟に連続して形成された複数の櫛歯片によって構成され、自由形状において長手中心における上面が上昇する方向に湾曲した形状に成形された合成樹脂製の上端側縁部櫛板と、この上端側縁部櫛板の長手両端部にそれぞれ設けられて長手端よりも中心寄りに配置され、上端側縁部櫛板の基板を踏段の上面に締結する締結具とが設けられる。
【００１５】
また、この発明に係るエスカレーターの踏段においては、上端側縁部櫛板の長手両端部及び長手中間に配置されて上端側縁部櫛板の基板を踏段の上面に締結する締結具が設けられる。
【００１６】
【発明の実施の形態】
実施の形態１．
図１〜図３は、この発明の実施の形態の一例を示す図で、図１は踏段の上端側縁部櫛板の装着作業状況を説明する図であり前述の図６相当図、図２は図１における上端側縁部櫛板の装着状況を示す図１相当図、図３は図２における上端側縁部櫛板の破損状態を説明する前述の図７相当図である。なお、図１〜図３の他は前述の図４〜図７と同様にエスカレーターの踏段が構成されている。図において、図４〜図７と同符号は相当部分を示す。
【００１７】
１５は上端側縁部櫛板で、踏段２の基体３の主枠上端側の縁部に設けられて長手が踏段２の幅方向に沿って装備され複数個が直列に配置されて、基板１６の上面に桟７に連続する複数の櫛歯片１１が形成され、また隣接した踏段２のライザ８に対向した基板１６の縁部に、ライザ８の溝に対向した櫛歯１２が突設されている。１３は締結具で、頭付きねじからなり上端側縁部櫛板１６の長手の中心及び両端部寄りにそれぞれ設けられて、基板１６に挿通されて基体３にねじ込まれている。
【００１８】
上記のように構成されたエスカレーターの踏段において、多数の踏段２が踏段鎖１によって無端状に連続されて主枠内を循環運転される。そして、主枠の端部に形成された乗降口に櫛板（図示しない）が設けられて、踏段２が乗降口を移動するときに、踏段２の桟７、上端側縁部櫛板１５の櫛歯片１１が乗降口の櫛板の下側を櫛板と噛み合う状態で通過する。
【００１９】
また、踏段２が主枠を移動するときに、互いに隣接した踏段２の相互が上下方向に相対変位する箇所では、踏段２のライザ８の溝とこの溝に対向した他の踏段２に設けられた上端側縁部櫛板１５の櫛歯１２が噛み合う状態で相対変位する。なお、上端側縁部櫛板１５は踏段２の基体３に対して図１に示すように長手の中心及び両端寄りがそれぞれ締結具１３によって締結されている。
【００２０】
そして、上端側縁部櫛板１５は注意色、すなわち黄色等に着色された合成樹脂によって製作されるのが一般的である。また、上端側縁部櫛板１５は耐衝撃性の高いポリカーボネート樹脂等の成形品が使用され、保守作業における利便性のために踏段２の幅方向長さを複数に分割した長さに製作されて、踏段２の基体３に締結具１３によって装着される。このように構成されることによって、踏段２が乗降口を通過するときに、互いに隣接する踏段２相互の境界を明瞭化するために上端側縁部櫛板１５が設けられる。
【００２１】
また、上端側縁部櫛板１５は合成樹脂が成形されて冷却した後における自由形状において、長手中心における上面が上昇する方向に湾曲した形状に成形される。すなわち、冷却後の自由形状において長手中心における上面が上昇する湾曲形状となるような金型を使用して射出成形される。なお、脱型直後に型枠等にはめて湾曲形状に矯正して製作してもよい。そして、このような形状の上端側縁部櫛板１５が、図１及び図２に示すように直線形状に弾性変形させて、長手の中心及び両端寄りがそれぞれ締結具１３によって踏段２の基体３上面に締結される。
【００２２】
そして、踏段２の清掃作業時に強アルカリ剤や溶剤等を含む床クリーナ剤が使用されると、踏段２に装着された上端側縁部櫛板１５に床クリーナ剤が付着して、特に内部応力が高くなっている締結具１３の締結孔箇所にクレージング現象によるクラックが発生する場合がある。
【００２３】
このような場合に、上端側縁部櫛板１５の長手中心の締結孔箇所が破断したときには、上端側縁部櫛板１５の長手の両端よりも中心寄りがそれぞれ締結具１３によって踏段２の基体３に上方から締結されているので、上端側縁部櫛板１５の自由形状復帰が阻止される。このため、図３に示すように上端側縁部櫛板１５の長手が踏段２の基体３に密着した状態、すなわち直線形状に保持される。
【００２４】
したがって、長手中心位置の締結具１３による締結孔箇所で上端側縁部櫛板１５が破断した場合であっても、長手中心が浮上することなく踏段２、すなわち上端側縁部櫛板１５が主枠の端部に設けられた乗降口を正常に通過する。これにより、長手中心が浮上した上端側縁部櫛板１５が乗降口の櫛板に衝突して櫛板が破損する等の不具合の発生を未然に防止することができる。
【００２５】
なお、上端側縁部櫛板１５の長手端部寄りにおける一方の締結具１３の締結孔箇所にクラックが発生して破断した場合にも、他方及び長手中心の締結具１３によって踏段２の基体３に上端側縁部櫛板１５が上方から締結されているので、上端側縁部櫛板１５の自由形状復帰が阻止される。このため、図３に示すように上端側縁部櫛板１５の長手が踏段２の基体３に密着した状態、すなわち直線形状に保持される。これによって、長手端部が浮上した上端側縁部櫛板１５が乗降口の板に衝突して、櫛板が破損する等の不具合の発生を未然に防止することができる。
【００２６】
【発明の効果】
この発明は以上説明したように、多数が無端状に連結されて傾斜して設置された主枠中を循環運転される踏段、これらの踏段の上面に設けられて長手が運転方向に沿って配置されて、踏段の踏み面を形成する複数本の桟と、踏段の上面の主枠上端側の縁部に設けられて長手が踏段の幅方向に沿って配置されて、基板及びこの基板の上面に踏段の桟に連続して形成された複数の櫛歯片によって構成され、自由形状において長手中心における上面が上昇する方向に湾曲した形状に成形された合成樹脂製の上端側縁部櫛板と、この上端側縁部櫛板の長手両端部にそれぞれ設けられて長手端よりも中心寄りに配置され、上端側縁部櫛板の基板を踏段の上面に締結する締結具とを設けたものである。
【００２７】
そして、踏段の清掃作業時の床クリーナ剤等が踏段に装着された上端側縁部櫛板に付着し、クレージング現象により締結具の締結孔箇所にクラックが発生して上端側縁部櫛板がそれの締結孔箇所で破断することがある。このときに、上端側縁部櫛板の長手端よりも中心寄りが締結具によって踏段の基体に上方から締結されているので、上端側縁部櫛板の自由形状復帰が阻止される。したがって、上端側縁部櫛板の長手が踏段の基体に密着した状態、すなわち直線形状に保持される。したがって、上端側縁部櫛板が長手において破断した場合であっても、破断箇所において上端側縁部櫛板が浮き上がることなく上端側縁部櫛板が主枠端部に設けられた乗降口を正常に通過する。これにより、浮き上がった上端側縁部櫛板が乗降口の櫛板に衝突して櫛板が破損する等の不具合の発生を未然に防止する効果がある。
【００２８】
また、この発明は以上説明したように、上端側縁部櫛板の長手両端部及び長手中間に配置されて上端側縁部櫛板の基板を踏段の上面に締結する締結具を設けたものである。
【００２９】
これによって、上端側縁部櫛板の長手両端部に設けられた締結具の締結孔箇所の両方において上端側縁部櫛板が破断した場合に、長手中間に配置された締結具によって上端側縁部櫛板の自由形状復帰が阻止される。したがって、上端側縁部櫛板の長手が踏段の基体に密着した状態、すなわち直線形状に保持される。このため、上端側縁部櫛板が長手両端部の両方において破断した場合であっても、破断箇所において上端側縁部櫛板が浮き上がることなく上端側縁部櫛板が主枠端部に設けられた乗降口を正常に通過する。これにより、浮き上がった上端側縁部櫛板が乗降口の櫛板に衝突して櫛板が破損する等の不具合の発生を未然に防止する効果がある。

[Problems to be solved by the invention]
In the steps of the conventional escalator as described above, the upper end side edge comb plate 9 is injection-molded into a shape in which a plurality of comb teeth 11 are formed on the upper side of the substrate 10. Therefore, the free shape of the upper edge side comb plate 9 after cooling of the molded product is a curved shape in which the upper surface of both ends of the substrate 10 is raised and the longitudinal center of the substrate 10 is lowered, that is, as shown in FIG. The shape becomes. This is because the upper edge side comb plate 9 has an asymmetrical shape composed of the comb teeth 11 and the substrate 16. The upper edge side comb plate 9 having such a curved shape is elastically deformed, and the longitudinal center and both ends thereof are fastened to the upper surface of the base 3 of the step 2 by the fasteners 13 so as to be mounted in a linear shape.

Further, when the step 2 moves on the main frame, the step 2 adjacent to each other is provided in the groove of the riser 8 of the step 2 and the other step 2 opposite to the groove at a position where the steps 2 are displaced relative to each other in the vertical direction. The upper end side edge comb plate 15 is relatively displaced in a state where the comb teeth 12 are engaged with each other. As shown in FIG. 1, the upper edge side comb plate 15 is fastened to the base 3 of the step 2 by fasteners 13 near the longitudinal center and both ends.
[0020]
The upper edge side comb plate 15 is generally made of a synthetic resin colored with a caution color, that is, yellow. Further, the upper end side edge comb plate 15 is made of a molded product such as polycarbonate resin having high impact resistance, and is manufactured to have a length obtained by dividing the length in the width direction of the step 2 into a plurality of parts for convenience in maintenance work. Thus, the fastener 3 is attached to the base 3 of the step 2. By being configured in this way, when the step 2 passes through the entrance / exit, the upper end side edge comb plate 15 is provided in order to clarify the boundary between the adjacent steps 2.
[0021]
The upper edge side comb plate 15 is formed into a curved shape in a direction in which the upper surface at the longitudinal center rises in a free shape after the synthetic resin is molded and cooled. That is, injection molding is performed using a mold that has a curved shape in which the upper surface at the longitudinal center rises in the free shape after cooling. It should be noted that immediately after demolding, it may be manufactured by being fitted into a mold or the like to be corrected to a curved shape. Then, the upper end side edge comb plate 15 having such a shape is elastically deformed into a linear shape as shown in FIGS. 1 and 2, and the base 3 of the step 2 by the fastener 13 at the longitudinal center and both ends. Fastened to the top surface.
[0022]
When a floor cleaner agent containing a strong alkali agent or a solvent is used during the cleaning operation of the step 2, the floor cleaner agent adheres to the upper edge side comb plate 15 attached to the step 2, and particularly the internal stress. In some cases, cracks due to the crazing phenomenon may occur in the fastening hole portion of the fastener 13 where the height is high.
[0023]
In such a case, when the fastening hole portion at the longitudinal center of the upper edge comb plate 15 is broken, the base of the step 2 is located closer to the center than the longitudinal ends of the upper edge comb plate 15 by the fasteners 13 respectively. 3 is fastened from above, so that the free shape return of the upper edge side comb plate 15 is prevented. For this reason, as shown in FIG. 3, the upper end side edge comb plate 15 is held in a state in which the length thereof is in close contact with the base 3 of the step 2, that is, in a linear shape.
[0024]
Therefore, even when the upper edge side comb plate 15 is broken at the fastening hole portion by the fastener 13 at the longitudinal center position, the step 2, that is, the upper edge side comb plate 15 is mainly used without the longitudinal center rising. It normally passes through the entrance / exit provided at the end of the frame. Accordingly, it is possible to prevent the occurrence of problems such as the upper end side edge comb plate 15 whose longitudinal center has floated colliding with the comb plate at the entrance / exit and the comb plate being damaged.
[0025]
Even when a crack occurs in the fastening hole portion of one fastener 13 near the longitudinal end portion of the upper edge side comb plate 15, the base 3 of the step 2 is formed by the other and longitudinal fastener 13. Since the upper end side edge comb plate 15 is fastened from above, the free shape return of the upper end side edge comb plate 15 is prevented. For this reason, as shown in FIG. 3, the upper end side edge comb plate 15 is held in a state in which the length thereof is in close contact with the base 3 of the step 2, that is, in a linear shape. Accordingly, it is possible to prevent the occurrence of problems such as the comb plate being damaged due to the upper end side edge comb plate 15 whose longitudinal end portion has floated colliding with the board of the entrance / exit.

[0027]
Then, floor cleaner or the like during the cleaning operation of the step adheres to the upper edge side comb plate attached to the step, and a crack occurs in the fastening hole portion of the fastener due to the crazing phenomenon, and the upper edge side comb plate becomes It may break at the fastening hole. At this time, the upper end side edge comb plate closer to the center than the longitudinal end is fastened to the base of the step by the fastener from above, so that the free shape return of the upper end side edge comb plate is prevented. Therefore, the upper end side edge comb plate is held in a state where it is in close contact with the base of the step, that is, in a linear shape. Therefore, even when the upper end side edge comb plate is broken in the longitudinal direction, the upper end side edge comb plate is not lifted up at the break point, and the entrance / exit where the upper end side edge comb plate is provided at the end of the main frame is provided.
