Description

本発明は、エスカレータに関するものである。 The present invention relates to an escalator.

エスカレータ（乗客コンベア）は、多数の踏段（ステップ）が連結された無端状の踏段チェーンが上階側及び下階側のスプロケットによって巻き掛けられ、これらのスプロケットの回転に伴って、各踏段に接続されたローラがレールを走行し、踏段チェーンとこれに連結された多数の踏段がスプロケットの間を循環移動するようになっている。従来のエスカレータのレールでは、レール上に落ちた油がレール内側を伝い踏段に流れることで、踏段が滑りやすくなるため踏段を頻繁に清掃する必要があった。 The escalator (passenger conveyor) is connected to each step as these sprockets rotate, with an endless chain of steps connected to a number of steps connected by upper and lower sprockets. The rolled roller travels on the rail, and the step chain and a number of steps connected to the step chain circulate between the sprockets. In conventional escalator rails, the oil that has fallen on the rails flows along the rails and flows to the steps, making the steps easy to slip, so the steps need to be cleaned frequently.

特許文献１のエスカレータでは、レール内側からの油漏れを抑制するために、踏段レールの転輪走行域よりも内側に油切り溝を全長に渡って形成し、下方の終端部に取付けたドレーンを通って下部の機械室床上に油を導いていた。また、エスカレータの油漏れの対策は、特許文献２や特許文献３にも記載されている。特許文献２のエスカレータでは、チェーンローラの転送面とステップローラの転送面を案内システムに設け、さらにオイル収集流路を設けることで潤滑オイルが滴り落ちるのを防止していた。特許文献３のエスカレータでは、前輪と後輪とを案内する一体型レールの前輪の案内部と後輪の案内部との中間位置にエスカレータ傾斜部の長手方向に亘って窪みを設け、チェーンから落下する油を窪みに溜めていた。 In the escalator of Patent Document 1, in order to suppress oil leakage from the inside of the rail, an oil drain groove is formed over the entire length inside the rolling travel area of the step rail, and a drain attached to the lower end portion is provided. Oil was led through the lower machine room floor. Further, countermeasures against escalator oil leakage are also described in Patent Document 2 and Patent Document 3. In the escalator of Patent Document 2, the transfer surface of the chain roller and the transfer surface of the step roller are provided in the guide system, and further an oil collecting passage is provided to prevent the lubricating oil from dripping. In the escalator of Patent Document 3, a depression is provided in the middle of the front wheel guide portion and the rear wheel guide portion of the integrated rail that guides the front wheel and the rear wheel over the longitudinal direction of the escalator inclined portion, and falls from the chain. The oil to be stored in the dent.

特開平７−２５７８６４号公報（０００８段〜００１１段、図１、図４）Japanese Unexamined Patent Publication No. 7-257864 (steps 0008 to 0011, FIGS. 1 and 4) 特開２００７−３９２４６号公報（００１５段、図４）JP 2007-39246 A (0015 stage, FIG. 4) 特開２００７−１０６５８０号公報（０００９段、００１０段、図２）JP 2007-106580 (0009, 0010, FIG. 2)

従来のエスカレータのレールでは、レール上に落ちた油がレール内側を伝い踏段に流れることで、踏段が滑りやすくなるため踏段を頻繁に清掃する必要があった。この解決策として、特許文献１、３では、レールから踏段への油漏れを抑制するために、油切り溝や窪みを施したレールを用いていた。また、特許文献１、２では、レール下部の終端部にドレーンを設けたり、レールの外側にオイル収集流路を設けたりしていた。 In conventional escalator rails, the oil that has fallen on the rails flows along the rails and flows to the steps, making the steps easy to slip, so the steps need to be cleaned frequently. As a solution to this problem, Patent Documents 1 and 3 use rails with oil drain grooves and depressions to suppress oil leakage from the rails to the steps. Moreover, in patent document 1, 2, the drain was provided in the terminal part of the rail lower part, or the oil collection flow path was provided in the outer side of the rail.

特許文献１、２のように、潤滑油を収集する経路を新たに設けると、部品点数や部品重量が増え、材料費が高くなる。又、レール継ぎ目からの油漏れを抑制するためには、レールのつなぎ目で油漏れ防止のコーキング処理等を行う必要があり、あるいは、レールをつなぎ目無く一体で製作する必要があり、レールの取付けや油漏れの処理に手間がかかっていた。 If a route for collecting lubricating oil is newly provided as in Patent Documents 1 and 2, the number of parts and the part weight increase, and the material cost increases. In addition, in order to suppress oil leakage from the rail joint, it is necessary to perform caulking processing to prevent oil leakage at the rail joints, or it is necessary to manufacture the rails integrally without joints. It took time and effort to handle the oil leak.

本発明は、上記のような問題点を解決するためになされたものであり、レール全長に渡って内側への油漏れを防止することを目的としている。 The present invention has been made to solve the above-described problems, and an object thereof is to prevent oil leakage to the inside over the entire length of the rail.

本発明のエスカレータは、駆動ローラが走行する駆動ローラ走行部と追従ローラが走行する追従ローラ走行部とを一体化した往路側レールの２本で対となる往路側レール対と、往路側レール対に対応して設けられた、片側２本の帰路側レールを有する帰路側レール対とを備える。往路側レールは、上方階側レール部と、下方階側レール部と、上方階側レール部と下方階側レール部とを接続する接続部材とを有し、上方階側レール部の下端部及び下方階側レール部の上端部は、往路側レールの長手方向に垂直な切断形状や、往路側レールの長手方向に対して９０度以外の略同一の傾斜角で傾斜した傾斜切断形状を有することを特徴とする。接続部材は、上方階側レール部の下端部と下方階側レール部の上端部とが突き合わされたレール接続部を包含するように、かつ上方階側レール部及び下方階側レール部の背面側に配置され、接続部材の下端部は、長手内側縁部から所定の傾斜角でもって下降し、長手外側縁部に達する傾斜形状を有することを特徴とする。 The escalator according to the present invention includes a forward-side rail pair, which is a pair of forward-side rails, in which a driving-roller traveling unit that the driving roller travels and a tracking-roller traveling unit that the following roller travels are integrated, and an outward-side rail pair. And a return-side rail pair having two return-side rails on one side. The forward rail has an upper floor rail, a lower floor rail, and a connecting member that connects the upper floor rail and the lower floor rail, the lower end of the upper floor rail, and The upper end portion of the lower floor side rail portion has a cutting shape perpendicular to the longitudinal direction of the outward rail, or an inclined cutting shape inclined at substantially the same inclination angle other than 90 degrees with respect to the longitudinal direction of the outward rail. It is characterized by. The connecting member includes a rail connecting portion in which the lower end portion of the upper floor side rail portion and the upper end portion of the lower floor side rail portion are abutted with each other, and the back side of the upper floor side rail portion and the lower floor side rail portion. The lower end portion of the connecting member has a slope shape that descends from the longitudinal inner edge with a predetermined tilt angle and reaches the longitudinal outer edge.

本発明のエスカレータによれば、上方階側レール部と下方階側レール部との背面側に配置された接続部材の下端部が、長手内側縁部から所定の傾斜角でもって下降し、長手外側縁部に達する傾斜形状を有するので、レール全長に渡って内側への油漏れを防止できる。 According to the escalator of the present invention, the lower end portion of the connecting member disposed on the back side of the upper floor side rail portion and the lower floor side rail portion descends from the longitudinal inner edge with a predetermined inclination angle, and the longitudinal outer side. Since it has an inclined shape reaching the edge, oil leakage to the inside can be prevented over the entire length of the rail.

It is the rail which formed the part 6b.

以下、図１〜図９に基づいて実施の形態１におけるエスカレータを説明する。エスカレータ５０は、図１に示すように鉄骨等で作られたトラス１、ステップ２、駆動機（図示せず）、ガラス３、手摺４、チェーン２０などで構成される。チェーン２０は環状に連結されているが、図１の上側の往路側チェーン７５と鉛直方向下側の帰路側チェーン８５とを区別して記載した。エスカレータのステップ２は、駆動ローラ５と追従ローラ６を介して乗客が乗る往路側の往路側レール７０の上に乗っており、駆動ローラ５に取付けた往路側チェーン７５を引き上げ又は下げることでステップ２を移動させている。 Hereinafter, the escalator in Embodiment 1 is demonstrated based on FIGS. As shown in FIG. 1, the escalator 50 includes a truss 1, a step 2, a driving machine (not shown), a glass 3, a handrail 4, a chain 20, and the like made of a steel frame or the like. Although the chain 20 is connected in an annular shape, the upper side chain 75 on the upper side and the lower side chain 85 on the lower side in FIG. Step 2 of the escalator rides on an outward path rail 70 on which the passenger rides via the driving roller 5 and the follower roller 6, and is stepped by raising or lowering the outward chain 75 attached to the driving roller 5. 2 is moved.

駆動ローラ５と往路側チェーン７５は一体となっており、給油装置等で往路側チェーン７５に給油する。乗客が乗る往路側の往路側レール７０は、例えば図４のように薄板をフォーミング加工することによって形成される。往路側レール７０は、上記の加工で図３、図４に示すように駆動ローラ走行部７０Ａと追従ローラ走行部７０Ｂとが一体に成形され、エスカレータ５０のレール部を構成する。駆動ローラ５が走行する面のエスカレータ内側（駆動ローラ走行部７０Ａの長手内側縁部）に、土手状の駆動ローラ側隆起部５ａが形成される。図３のように、往路側レール７０の駆動ローラ走行部７０Ａにおける平坦部に駆動ローラ５を乗せ、往路側レール７０の追従ローラ走行部７０Ｂにおける平坦部に追従ローラ６を乗せて往路側チェーン７５を駆動させることで、ステップ２を走行させる。 The drive roller 5 and the forward path side chain 75 are integrated, and the forward path side chain 75 is lubricated by an oiling device or the like. The forward side rail 70 on the forward side on which the passenger rides is formed by forming a thin plate as shown in FIG. 4, for example. As shown in FIGS. 3 and 4, the forward-side rail 70 is formed integrally with the driving roller traveling portion 70 A and the follower roller traveling portion 70 B as shown in FIGS. 3 and 4, thereby constituting the rail portion of the escalator 50. A bank-like driving roller-side raised portion 5a is formed inside the escalator (the longitudinal inner edge of the driving roller traveling portion 70A) on the surface on which the driving roller 5 travels. As shown in FIG. 3, the driving roller 5 is placed on the flat portion of the driving roller traveling portion 70 A of the forward rail 70, and the tracking roller 6 is placed on the flat portion of the tracking roller traveling portion 70 B of the forward rail 70. To drive step 2.

往路側レール７０は、エスカレータの製造上の都合等により、一体のレールで製作できずに分割する場合がある。この場合には、図５に示すように上方階側往路レール部（適宜、上方階側レール部とも称す）７１と下方階側往路レール部（適宜、下方階側レール部とも称す）７２に分割される。また、往路側レール７０は、図６に示すように上方階側往路レール部７１と下方階側往路レール部７２とが接続されるレール接続部７６において、接続部材（適宜、レール接続部材とも称す）１０及び固定板１６を介在させてボルト９等で固定して接続される。具体的には、上方階側往路レール部７１及び下方階側往路レール部７２は、レール接続部７６において、接続部材１０及び固定板１６によって挟まれることで、固定される。接続部材１０は、上方階側レール部７１の下端部７１ｃと下方階側レール部７２の上端部７２ｃとが突き合わされたレール接続部７６を包含するように、かつ上方階側レール部７１及び下方階側レール部７２の背面側に配置されている。 The forward rail 70 may be divided because it cannot be manufactured as a single rail due to manufacturing reasons of the escalator. In this case, as shown in FIG. 5, it is divided into an upper floor side forward rail part (also referred to as an upper floor side rail part as appropriate) 71 and a lower floor side forward rail part (also referred to as a lower floor side rail part as appropriate) 72. Is done. Further, as shown in FIG. 6, the forward rail 70 is connected to a connecting member (also referred to as a rail connecting member as appropriate) in a rail connecting portion 76 to which an upper floor side forward rail portion 71 and a lower floor side forward rail portion 72 are connected. ) 10 and fixing plate 16 are interposed and fixed with bolts 9 or the like. Specifically, the upper floor side forward rail portion 71 and the lower floor side forward rail portion 72 are fixed by being sandwiched between the connecting member 10 and the fixing plate 16 in the rail connecting portion 76. The connecting member 10 includes a rail connecting portion 76 in which the lower end portion 71c of the upper floor side rail portion 71 and the upper end portion 72c of the lower floor side rail portion 72 are abutted with each other, and the upper floor side rail portion 71 and the lower portion. It is arranged on the back side of the floor side rail portion 72.

この接続部材１０は、下方階側の切断形状が、エスカレータの上方から見て下方に向かって外側に広がる方向に切断された形状になっている。すなわち、接続部材１０の下端部１０ａが、エスカレータの上方から見て、内側が高い位置にあり、かつ外側が低い位置にあるように傾斜した形状である。また、別の表現をすれば、接続部材１０は、接続部材１０の外側が内側よりも下側に延伸した形状になっており、外側端部１０ｃの長さが内側端部１０ｄよいも長くなっている。そして、これらの接続部材１０の傾斜状の下端部１０ａは、後述するように往路側レール７０上に落ちた滴下油をオイルパン１４（図１４参照）等に案内滴下させる機能を有する。 The connection member 10 has a shape in which the cut shape on the lower floor side is cut in a direction that spreads outward as seen from above the escalator. That is, the lower end portion 10a of the connecting member 10 has a shape that is inclined so that the inside is at a high position and the outside is at a low position as viewed from above the escalator. In other words, the connection member 10 has a shape in which the outer side of the connection member 10 extends downward from the inner side, and the length of the outer end 10c is longer than the inner end 10d. ing. The inclined lower end portion 10a of these connecting members 10 has a function of guiding and dropping the dropped oil that has fallen on the forward path side rail 70 to the oil pan 14 (see FIG. 14) or the like, as will be described later.

実施の形態１のエスカレータ５０は、このような構成により、図３に示すように、往路側チェーン７５に給油された油が、駆動ローラ側隆起部５ａを越えることなく経路２１のように流れ、駆動ローラ走行部７０Ａの外側へ流れ落ちる。さらに、図５に示すように、レール接続部７６においても同様に、上方階側から伝わった油は、レール接続部７６やレール接続部７６以外の駆動ローラ走行部（駆動ローラ走行部７０Ａ、追従ローラ走行部７０Ｂ）の外側を伝ってレール裏面に流れた後、レール接続部７６から往路側レール７０の下方階側往路レール部７２に入り、レール接続部材１０の外側端部１０ｃや内側端部１０ｄを流れる。レール接続部材１０の外側端部１０ｃを流れる油は経路２２のように流れ、レール接続部材１０の内側端部１０ｄを流れる油は、経路２３のようにレール接続部材１０の傾斜状の下端部１０ａに沿って油が外側に流れ落ちる。下方階側往路レール部７２においても、往路側チェーン７５に給油された油が、駆動ローラ側隆起部５ａを越えることなく経路２１のように流れ、駆動ローラ走行部７０Ａの外側へ流れ落ちる。 In the escalator 50 according to the first embodiment, as shown in FIG. 3, the oil supplied to the forward path side chain 75 flows like the path 21 without passing through the driving roller side raised portion 5a. It flows down to the outside of the driving roller traveling portion 70A. Further, as shown in FIG. 5, the oil transmitted from the upper floor side in the rail connecting portion 76 is also the same as the rail connecting portion 76 and the driving roller traveling portion other than the rail connecting portion 76 (the driving roller traveling portion 70 A, follow-up). After traveling on the back side of the rail through the outside of the roller running portion 70B), the rail connecting portion 76 enters the lower floor side outward rail portion 72 of the outward path side rail 70, and the outer end portion 10c and inner end portion of the rail connecting member 10 It flows through 10d. The oil flowing through the outer end portion 10c of the rail connection member 10 flows like a path 22, and the oil flowing through the inner end portion 10d of the rail connection member 10 is inclined lower end 10a of the rail connection member 10 like a path 23. Oil flows down along. Also in the lower floor side forward rail portion 72, the oil supplied to the forward side chain 75 flows like the path 21 without passing through the driving roller side raised portion 5a, and flows down to the outside of the driving roller traveling portion 70A.

又、図７に示すように、駆動ローラ走行部７０Ａの駆動ローラ側隆起部５ａに沿って流れた油が、レール接続部７６から往路側レール７０の下方階側往路レール部７２に入り、レール接続部材１０の外側端部１０ｃや内側端部１０ｄを流れる。レール接続部材１０の外側端部１０ｃを流れる油は経路２４のように流れ、レール接続部材１０の内側端部１０ｄを流れる油は、経路２５のようにレール接続部材１０の傾斜状の下端部１０ａに沿って油が外側に流れ落ちる。 Further, as shown in FIG. 7, the oil that has flowed along the driving roller side raised portion 5a of the driving roller traveling portion 70A enters the lower floor side outward rail portion 72 of the outward rail 70 from the rail connecting portion 76, and the rail It flows through the outer end 10c and the inner end 10d of the connecting member 10. The oil flowing through the outer end 10c of the rail connection member 10 flows like a path 24, and the oil flowing through the inner end 10d of the rail connection member 10 is inclined lower end 10a of the rail connection member 10 like a path 25. Oil flows down along.

上方階側から伝わった油が、レール接続部材１０の外周に沿って流れ、最終的に往路側レール７０の外側に流れ落ちるため、実施の形態１のエスカレータ５０は、ステップ２の踏板に油が付着しなくなり、乗客が踏板面に乗った時のすべりを抑制できるといった安全性を向上させることができる。又、実施の形態１のエスカレータ５０は、ステップ２を清掃するといった手間を省くことができる。 Since the oil transmitted from the upper floor side flows along the outer periphery of the rail connection member 10 and finally flows down to the outside of the outward path side rail 70, the escalator 50 according to the first embodiment adheres to the tread in step 2. Therefore, it is possible to improve safety such that slipping when the passenger gets on the tread surface can be suppressed. Further, the escalator 50 according to the first embodiment can save the trouble of cleaning step 2.

さらに、実施の形態１のエスカレータ５０は、駆動ローラ走行部７０Ａに駆動ローラ側隆起部５ａを設けることによって、エスカレータ組立やメンテナンス等で踏段を取外した状態でチェーンを走行させた際に、チェーン２０の脱輪を防止できるため、エスカレータ走行の安全性を高めることができる。特許文献１のエスカレータは、エスカレータ組立時やメンテナンス等で踏段を取外した状態でチェーンを走行させた際に、チェーンがエスカレータの幅方向に振れ、脱輪してしまうという問題があった。これとは異なり、実施の形態１のエスカレータ５０は、上記のように、エスカレータ組立やメンテナンス等で踏段を取外した状態でチェーンを走行させた際に、チェーン２０の脱輪を防止できるため、エスカレータ走行の安全性を高めることができる。 Further, the escalator 50 according to the first embodiment is provided with the driving roller side raised portion 5a in the driving roller traveling portion 70A, so that when the chain is traveled with the steps removed in escalator assembly or maintenance, the chain 20 Therefore, the safety of escalator travel can be improved. The escalator of Patent Document 1 has a problem that the chain swings in the width direction of the escalator when the chain is run with the steps removed during escalator assembly or maintenance. Unlike the above, the escalator 50 according to the first embodiment can prevent the chain 20 from being removed when the chain is run with the steps removed during escalator assembly or maintenance as described above. Driving safety can be improved.

なお、図３〜図７に示した例は、駆動ローラ走行部７０Ａに駆動ローラ側隆起部５ａを形成した場合であるが、図８の第１変形例のように、追従ローラ走行部７０Ｂの長手内側縁部に沿って土手状の追従ローラ側隆起部６ｂを設けることもできる。図２に示した第２変形例のように、駆動ローラ走行部７０Ａと追従ローラ走行部７０Ｂの双方に、駆動ローラ側隆起部５ａと追従ローラ側隆起部６ｂとをそれぞれ設けることも可能である。 The example shown in FIGS. 3 to 7 is a case where the driving roller side raised portion 5a is formed in the driving roller traveling portion 70A. However, as in the first modified example of FIG. A bank-like follower roller side raised portion 6b may be provided along the longitudinal inner edge. As in the second modification shown in FIG. 2, it is also possible to provide the drive roller side raised portion 5a and the follower roller side raised portion 6b on both the drive roller running portion 70A and the follower roller running portion 70B. .

図８に示した第１変形例の往路側レール７０や、図２に示した第２変形例の往路側レール７０を備えたエスカレータ５０においても、駆動ローラ側隆起部５ａや追従ローラ側隆起部６ｂがあることにより、往路側レール７０より内側への油の侵入を防止するように油の流れを抑制できる。このため、実施の形態１のエスカレータ５０は、ステップ２への油の滴下を阻止することができ、安全性を向上、ステップ清掃の手間を省くことができる。また、実施の形態１のエスカレータ５０は、駆動ローラ走行部７０Ａに設けられた駆動ローラ側隆起部５ａや、追従ローラ走行部７０Ｂに設けられた追従ローラ側隆起部６ｂによって、エスカレータ組立やメンテナンス等で踏段を取外した状態でチェーンを走行させた際に、チェーン２０の脱輪を防止できるため、エスカレータ走行の安全性を高めることができる。 Also in the escalator 50 including the forward path side rail 70 of the first modified example shown in FIG. 8 and the forward path side rail 70 of the second modified example shown in FIG. 2, the driving roller side raised portion 5a and the follower roller side raised portion By having 6b, the flow of the oil can be suppressed so as to prevent the intrusion of the oil inward from the outward path side rail 70.

Since the chain 20 can be prevented from being removed when the chain is run with the step removed, the safety of escalator running can be improved.

また、往路側レール７０は、図９に示した第３変形例の往路側レール７０でもよい。第３変形例の往路側レール７０は、駆動ローラ走行部７０Ａの駆動ローラ側と追従ローラ走行部７０Ｂの追従ローラ側の両方に隆起部（図４の駆動ローラ側隆起部５ａや図８の追従ローラ側隆起部６ｂ）が無い例である。この場合でも、実施の形態１のエスカレータ５０は、下方階側の切断形状が、エスカレータの上方から見て下方に向かって外側に広がる方向に切断されたレール接続部材１０により、上方階側往路レール部７１及び下方階側往路レール部７２を接続することで、図５と同様にチェーン２０に給油された油がレール接続部７６にて駆動ローラ走行部７０Ａの外側へ流れ落ち、ステップ２への油の滴下を阻止することができる。 Further, the outward path rail 70 may be the outward path rail 70 of the third modified example shown in FIG. The forward path rail 70 of the third modified example has raised portions (the driven roller side raised portion 5a in FIG. 4 and the follower in FIG. 8) on both the drive roller side of the drive roller running portion 70A and the follower roller side of the follower roller running portion 70B. This is an example in which there is no roller-side raised portion 6b). Even in this case, the escalator 50 according to the first embodiment is configured so that the lower floor side cut shape is cut by the rail connecting member 10 which is cut in a direction extending outward as viewed from above the escalator. By connecting the section 71 and the lower floor side forward rail section 72, the oil supplied to the chain 20 flows down to the outside of the driving roller traveling section 70A at the rail connection section 76 as in FIG. Can be prevented from dripping.

The lower end portion 71 c of the rail portion 71 and the upper end portion 72 c of the lower floor side rail portion 72 have a cut shape perpendicular to the longitudinal direction of the forward path side rail 70. The connecting member 10 includes a rail connecting portion 76 in which the lower end portion 71c of the upper floor side rail portion 71 and the upper end portion 72c of the lower floor side rail portion 72 are abutted with each other, and the upper floor side rail portion 71 and the lower portion. The lower end portion 10a of the connecting member 10 is arranged on the back side of the floor side rail portion 72, and has a slope shape that descends from the longitudinal inner edge portion with a predetermined inclination angle and reaches the longitudinal outer edge portion. . Due to the characteristics of the forward rail 70, the escalator 50 according to the first embodiment is configured such that the lower end portion 10a of the connecting member 10 disposed on the back side of the upper floor rail portion 71 and the lower floor rail portion 72 Since it has an inclined shape that descends from the edge with a predetermined inclination angle and reaches the longitudinal outer edge, it is possible to prevent oil entering from the rail connection portion 76 from moving inward by the lower end portion 10a of the connection member 10. It is possible to prevent oil leakage to the inside over the entire length of the rail.

実施の形態２．
図１０は本発明の実施の形態２による往路側レールの接続部を示す図であり、図１１は図１０の往路側レールの接続部における油の流れを説明する図である。実施の形態２のエスカレータ５０は、接続部材１０の形状が実施の形態１とは異なったものである。実施の形態２の接続部材１０の形状は、接続部材１０の下端部１０ａと上端部１０ｂが、エスカレータの上方から見て、内側が高い位置にあり、かつ外側が低い位置にあるように傾斜した形状である。Embodiment 2. FIG.
FIG. 10 is a view showing the connecting portion of the forward rail according to the second embodiment of the present invention, and FIG. 11 is a view for explaining the oil flow in the connecting portion of the outward rail in FIG. In the escalator 50 of the second embodiment, the shape of the connecting member 10 is different from that of the first embodiment. The shape of the connecting member 10 according to the second embodiment is inclined so that the lower end portion 10a and the upper end portion 10b of the connecting member 10 are at a high position on the inside and at a low position on the outside as viewed from above the escalator. Shape.

実施の形態２のエスカレータ５０は、このような構成により、図３に示すように、往路側チェーン７５に給油された油は、駆動ローラ側隆起部５ａを越えることなく経路２１のように流れ、駆動ローラ走行部７０Ａの外側へ流れ落ちる。さらに、図１０に示すように、レール接続部７６においても同様に、上方階側から伝わった油は、レール接続部７６やレール接続部７６以外の駆動ローラ走行部（駆動ローラ走行部７０Ａ、追従ローラ走行部７０Ｂ）の外側を伝ってレール裏面に流れた後、レール接続部７６から往路側レール７０の下方階側往路レール部７２に入り、レール接続部材１０の外側端部１０ｃや内側端部１０ｄを流れる。レール接続部材１０の外側端部１０ｃを流れる油は経路２２のように流れ、レール接続部材１０の内側端部１０ｄを流れる油は、経路２３のようにレール接続部材１０の傾斜状の下端部１０ａに沿って油が外側に流れ落ちる。 In the escalator 50 of the second embodiment, as shown in FIG. 3, the oil supplied to the forward path side chain 75 flows like the path 21 without passing through the driving roller side raised portion 5a. It flows down to the outside of the driving roller traveling portion 70A. Furthermore, as shown in FIG. 10, the oil transmitted from the upper floor side in the rail connecting portion 76 is also the same as the rail connecting portion 76 and the driving roller traveling portion other than the rail connecting portion 76 (the driving roller traveling portion 70 A, follow-up). After traveling on the back side of the rail through the outside of the roller running portion 70B), the rail connecting portion 76 enters the lower floor side outward rail portion 72 of the outward path side rail 70, and the outer end portion 10c and inner end portion of the rail connecting member 10 It flows through 10d. The oil flowing through the outer end portion 10c of the rail connection member 10 flows like a path 22, and the oil flowing through the inner end portion 10d of the rail connection member 10 is inclined lower end 10a of the rail connection member 10 like a path 23. Oil flows down along.

又、図１１に示すように、駆動ローラ走行部７０Ａの駆動ローラ側隆起部５ａに沿って流れた油が、レール接続部７６から往路側レール７０の下方階側往路レール部７２に入り、レール接続部材１０の外側端部１０ｃや内側端部１０ｄを流れる。レール接続部材１０の外側端部１０ｃを流れる油は経路２４のように流れ、レール接続部材１０の内側端部１０ｄを流れる油は、経路２５のようにレール接続部材１０の傾斜状の下端部１０ａに沿って油が外側に流れ落ちる。 Further, as shown in FIG. 11, oil that flows along the driving roller side raised portion 5a of the driving roller traveling portion 70A enters the lower floor side outward rail portion 72 of the outward route rail 70 from the rail connecting portion 76, and enters the rail It flows through the outer end 10c and the inner end 10d of the connecting member 10. The oil flowing through the outer end 10c of the rail connection member 10 flows like a path 24, and the oil flowing through the inner end 10d of the rail connection member 10 is inclined lower end 10a of the rail connection member 10 like a path 25. Oil flows down along.

上方階側から伝わった油が、レール接続部材１０の外周に沿って流れ、最終的に往路側レール７０の外側に流れ落ちるため、実施の形態２のエスカレータ５０は、ステップ２の踏板に油が付着しなくなり、乗客が踏板面に乗った時のすべりを抑制できるといった安全性を向上させることができる。又、実施の形態２のエスカレータ５０は、ステップ２を清掃するといった手間を省くことができる。 Since the oil transmitted from the upper floor side flows along the outer periphery of the rail connection member 10 and finally flows down to the outside of the outward path rail 70, the escalator 50 of the second embodiment adheres to the tread of step 2 Therefore, it is possible to improve safety such that slipping when the passenger gets on the tread surface can be suppressed. Moreover, the escalator 50 of Embodiment 2 can save the effort of cleaning step 2. FIG.

又、実施の形態２のエスカレータ５０は、レール接続部材１０の下方階側（下端部１０ａ）と上方階側（上端部１０ｂ）の切断形状が同じ方向に傾斜しているため、レール接続部材１０を製作する際、帯状の鋼材を斜めに切断することで、連続的に斜め切断することができる。実施の形態２のエスカレータ５０は、連続的に斜め切断することで、レール接続部材１０を製作できるため、レール接続部材１０の加工時間を低減させることができる。 In the escalator 50 according to the second embodiment, the rail connecting member 10 has a lower floor side (lower end portion 10a) and an upper floor side (upper end portion 10b) cut in the same direction. Can be continuously cut obliquely by cutting the strip-shaped steel material obliquely. Since the escalator 50 of Embodiment 2 can manufacture the rail connection member 10 by continuously performing oblique cutting, the processing time of the rail connection member 10 can be reduced.

実施の形態３．
図１２は、本発明の実施の形態３における往路側レール７０の接続部を示す図である。図１２の往路側レール７０は、左右のレールともに、傾斜状の下端部７１ｃを有する上方階側往路レール部７１と、下端部７１ｃに対向する傾斜状の上端部７２ｃを有する下方階側往路レール部７２を備えている。上方階側往路レール部７１の下端部７１ｃの傾斜角度は、下方階側往路レール部７２の上端部７２ｃの傾斜角度と多少の差があってもよく、すなわち、略同一であればよい。図１２の往路側レール７０は、左右のレールともに、同方向に所定の傾斜角でもって下降し傾斜状に切断されている。実施の形態３のエスカレータ５０は、傾斜状の下端部７１ｃとこれに対向する下方階側往路レール部７２の上端部７２ｃの切断面は、上方階側の傾斜状の下端部７１ｃと衝合（突合）する傾斜状に形成される。このことで、実施の形態３のエスカレータ５０は、一度工場内で組立てたエスカレータ５０を分割し据付現場にて再接合する際、左右のレール（往路側レール７０）がトラス１に固定されていても、レール接続部７６におけるレールの傾斜方向が同方向のため、左右のレールの断面を合わせる作業を効率的にできる。なお、左右のレールの傾斜角度は、それぞれ異なっていてもよい。Embodiment 3 FIG.
FIG. 12 is a diagram illustrating a connection portion of the outward path side rail 70 according to the third embodiment of the present invention. The forward rail 70 shown in FIG. 12 includes an upper floor forward rail portion 71 having an inclined lower end portion 71c and a lower floor side forward rail having an inclined upper end portion 72c facing the lower end portion 71c for both the left and right rails. A portion 72 is provided. The inclination angle of the lower end 71c of the upper floor side forward rail portion 71 may be slightly different from the inclination angle of the upper end portion 72c of the lower floor side outward rail portion 72, that is, it may be substantially the same. The forward-side rail 70 in FIG. 12 is lowered at a predetermined inclination angle in the same direction in both the left and right rails and is cut into an inclined shape. In the escalator 50 according to the third embodiment, the cut surface of the inclined lower end portion 71c and the upper end portion 72c of the lower floor side forward rail portion 72 opposed thereto collides with the inclined lower end portion 71c on the upper floor side ( It is formed in a slanted shape. As a result, the escalator 50 of the third embodiment has the left and right rails (outward rail 70) fixed to the truss 1 when the escalator 50 once assembled in the factory is divided and rejoined at the installation site. However, since the rail inclination direction in the rail connecting portion 76 is the same direction, the work of matching the cross sections of the left and right rails can be performed efficiently. Note that the inclination angles of the left and right rails may be different from each other.

さらに、実施の形態３のエスカレータ５０は、上方階側往路レール部７１の傾斜状の下端部７１ｃと下方階側往路レール部７２の傾斜状の上端部７２ｃとの接続部間は密着させても良いが、１〜３ｍｍ程度のレール隙間７０Ｇを設けることもできる。実施の形態３のエスカレータ５０は、レール隙間７０Ｇを設けることで、上方階側往路レール部７１と下方階側往路レール部７２とをつき合わせて取り付けることが不要になるため、レールの切断精度を緩和できる。かつ、実施の形態３のエスカレータ５０は、衝合（突合）する部分が傾斜状に切断されているため、レール隙間７０Ｇにローラ（駆動ローラ５、追従ローラ６）が通過する際に上方階側往路レール部７１と下方階側往路レール部７２の両方に乗移り、ローラがレール隙間７０Ｇに落ちることなく通過することで、異音や振動無くエスカレータ５０を稼動させることができる。 Furthermore, the escalator 50 according to the third embodiment may be configured such that the connection between the inclined lower end portion 71c of the upper floor side forward rail portion 71 and the inclined upper end portion 72c of the lower floor side forward rail portion 72 is in close contact. Although it is good, a rail gap 70G of about 1 to 3 mm can also be provided. Since the escalator 50 according to the third embodiment is provided with the rail gap 70G, it is not necessary to attach the upper floor side forward rail portion 71 and the lower floor side forward rail portion 72 together. Can be relaxed. In addition, the escalator 50 according to the third embodiment has an abutting (butting) portion that is cut in an inclined manner, so that when the rollers (the driving roller 5 and the following roller 6) pass through the rail gap 70G, the upper floor side The escalator 50 can be operated without abnormal noise or vibration by transferring to both the outward rail portion 71 and the lower floor-side outward rail portion 72 without passing through the rail gap 70G.

実施の形態３のエスカレータ５０は、上方階側と下方階側を接続する接続部材１０の下方階側の切断形状が、実施の形態１や実施の形態２と同様に、エスカレータの上方から見て下方に向かって外側に広がる方向に切断され、すなわち、接続部材１０の下端部１０ａが、エスカレータの上方から見て、内側が高い位置にあり、かつ外側が低い位置にあるように傾斜した形状である。また、実施の形態３のエスカレータ５０は、右側の往路側レール７０において、接続部材１０の端面（内側端部１０ｄ）を往路側レール７０の内側に合せた。このようにすることで、図１２の経路２６や経路２８のように、上方階側から流れる油は往路側レール７０のレール隙間７０Ｇからレール裏面に流れる。レール隙間７０Ｇからレール裏面に流れた油は、図１２の経路２７のようにレール接続部材１０の外側端部１０ｃを伝ってステップ２の外側へ流れ、又、図１２の経路２９のように、レール接続部材１０の下端部１０ａを伝ってステップ２の外側へ流れる。このため、実施の形態３のエスカレータ５０は、レール接続部材１０の外側端部１０ｃと下端部１０ａとがつながる先端部から油が滴下し、傾斜状のレール接続部７６ごとに油をオイルパン１４に落とすことができる。 In the escalator 50 according to the third embodiment, the cut shape on the lower floor side of the connecting member 10 that connects the upper floor side and the lower floor side is viewed from above the escalator, as in the first and second embodiments. Cut in a direction that spreads outward toward the bottom, that is, the lower end portion 10a of the connecting member 10 is inclined so that the inside is at a high position and the outside is at a low position when viewed from above the escalator. is there. In the escalator 50 according to the third embodiment, the end surface (inner end portion 10 d) of the connecting member 10 is aligned with the inner side of the forward path side rail 70 in the rightward forward path rail 70. By doing in this way, the oil which flows from the upper floor side flows from the rail clearance 70G of the forward path side rail 70 to the back surface of the rail like the path 26 and the path 28 in FIG. The oil that has flowed from the rail gap 70G to the rear surface of the rail flows along the outer end portion 10c of the rail connecting member 10 to the outside of Step 2 as shown in the path 27 of FIG. 12, and as shown in the path 29 of FIG. It flows to the outside of step 2 along the lower end portion 10a of the rail connection member 10. For this reason, in the escalator 50 according to the third embodiment, oil is dripped from the front end portion where the outer end portion 10c and the lower end portion 10a of the rail connection member 10 are connected, and the oil is supplied to the oil pan 14 for each inclined rail connection portion 76. Can be dropped.

同方向に傾斜状に切断された往路側レール７０の内、上方から見て内側に下がって傾斜した往路側レール７０（図１２において右側）は、油が傾斜部（傾斜状の下端部７１ｃ、上端部７２ｃ）の断面を伝って内側に流れる。このため、実施の形態３のエスカレータ５０は、接続部材１０の端面（内側端部１０ｄ）を往路側レール７０の内側に合せることで、レール内側を流れた油を確実に接続部材１０に伝え、接続部材１０の傾斜部（傾斜状の下端部１０ａ）を伝ってステップ２の外側へ流すことができる。なお、図１２では、左側の往路側レール７０においても、接続部材１０の端面（内側端部１０ｄ）を往路側レール７０の内側に合せた例を示した。 Of the forward rails 70 that are cut in the same direction and inclined, the forward rail 70 (right side in FIG. 12) that is inclined inwardly when viewed from above has an oil inclined portion (an inclined lower end portion 71c, It flows inward along the cross section of the upper end 72c). For this reason, the escalator 50 according to the third embodiment reliably transmits the oil flowing inside the rail to the connecting member 10 by aligning the end surface (inner end portion 10d) of the connecting member 10 with the inner side of the forward path side rail 70. It can flow to the outside of step 2 along the inclined portion (inclined lower end portion 10a) of the connecting member 10. FIG. 12 shows an example in which the end surface (inner end portion 10 d) of the connection member 10 is also aligned with the inner side of the outward path rail 70 in the left outward path rail 70.

往路側レール７０を一体もしくはレール接続部７６を密着させて接続した場合、往路側レール７０上に落ちた埃は下方階側往路レール部７２に溜まり、ステップ２の振動やステップ２の流れに影響を与える。この実施の形態３のようにレール隙間７０Ｇを設けて往路側レール７０のレール接続部７６ごとに油と埃を一緒にオイルパン１４に落とすことで、実施の形態３のエスカレータ５０は、下方階側往路レール部７２に埃が溜まらなくなり、下方階側往路レール部７２の清掃作業を省くことができる。 When the forward rail 70 is connected integrally or with the rail connection portion 76 closely attached, dust that has fallen on the forward rail 70 accumulates on the lower floor rail 72 and affects the vibration of step 2 and the flow of step 2. give. The escalator 50 according to the third embodiment is provided on the lower floor by providing a rail gap 70G as in the third embodiment and dropping oil and dust together with the rail connecting portion 76 of the forward rail 70 on the oil pan 14. Dust does not accumulate in the side outward rail portion 72, and the cleaning work of the lower floor side outward rail portion 72 can be omitted.

以上のように、実施の形態３のエスカレータ５０は、駆動ローラ５が走行する駆動ローラ走行部７０Ａと追従ローラ６が走行する追従ローラ走行部７０Ｂとを一体化した往路側レール７０の２本で対となる往路側レール対と、往路側レール対に対応して設けられた、片側２本の帰路側レール８０を有する帰路側レール対とを備える。往路側レール７０は、上方階側レール部７１と、下方階側レール部７２と、上方階側レール部７１と下方階側レール部７２とを接続する接続部材１０とを有し、上方階側レール部７１の下端部７１ｃ及び下方階側レール部７２の上端部７２ｃは、往路側レール７０の長手方向に対して９０度以外の略同一の傾斜角で傾斜した傾斜切断形状を有することを特徴とする。接続部材１０は、上方階側レール部７１の下端部７１ｃと下方階側レール部７２の上端部７２ｃとが突き合わされたレール接続部７６を包含するように、かつ上方階側レール部７１及び下方階側レール部７２の背面側に配置され、接続部材１０の下端部１０ａは、長手内側縁部から所定の傾斜角でもって下降し、長手外側縁部に達する傾斜形状を有することを特徴とする。この往路側レール７０の特徴により、実施の形態３のエスカレータ５０は、上方階側レール部７１と下方階側レール部７２との背面側に配置された接続部材１０の下端部１０ａが、長手内側縁部から所定の傾斜角でもって下降し、長手外側縁部に達する傾斜形状を有するので、レール接続部７６から入った油が接続部材１０の下端部１０ａにより内側へ移動するのを防ぐことができ、レール全長に渡って内側への油漏れを防止できる。 As described above, the escalator 50 according to the third embodiment includes two of the forward rails 70 in which the driving roller traveling portion 70A where the driving roller 5 travels and the tracking roller traveling portion 70B where the tracking roller 6 travels are integrated. A pair of forward rails and a return rail pair having two return rails 80 on one side provided corresponding to the forward rail pairs. The forward rail 70 includes an upper floor rail 71, a lower floor rail 72, and a connecting member 10 that connects the upper floor rail 71 and the lower rail 72, and is on the upper floor. The lower end portion 71 c of the rail portion 71 and the upper end portion 72 c of the lower floor side rail portion 72 have an inclined cut shape that is inclined at substantially the same inclination angle other than 90 degrees with respect to the longitudinal direction of the outward path side rail 70. And The connecting member 10 includes a rail connecting portion 76 in which the lower end portion 71c of the upper floor side rail portion 71 and the upper end portion 72c of the lower floor side rail portion 72 are abutted with each other, and the upper floor side rail portion 71 and the lower portion. The lower end portion 10a of the connecting member 10 is arranged on the back side of the floor side rail portion 72, and has a slope shape that descends from the longitudinal inner edge portion with a predetermined inclination angle and reaches the longitudinal outer edge portion. . Due to the characteristics of the forward rail 70, the escalator 50 according to the third embodiment is such that the lower end portion 10a of the connecting member 10 disposed on the back side of the upper floor rail portion 71 and the lower floor rail portion 72 Since it has an inclined shape that descends from the edge with a predetermined inclination angle and reaches the longitudinal outer edge, it is possible to prevent oil entering from the rail connection portion 76 from moving inward by the lower end portion 10a of the connection member 10.

FIG. 13 is a diagram illustrating a connecting portion of the outward path rail according to the fourth embodiment of the present invention. The forward path rail 70 in FIG. 13 includes an upper floor side forward rail section 71 having an inclined lower end 71c and a lower floor side forward rail having an inclined upper end 72c facing the lower end 71c for both the left and right rails. A portion 72 is provided. The inclination angle of the lower end 71c of the upper floor side forward rail portion 71 may be slightly different from the inclination angle of the upper end portion 72c of the lower floor side outward rail portion 72, that is, it may be substantially the same. The forward path side rail 70 in FIG. 13 is lowered at a predetermined inclination angle in both the left and right rails and cut into an inclined shape. Further, the shape of the connecting member 10 is the same as that shown in FIG. 5 of the first embodiment. The cut surfaces of the inclined lower end portion 71c of the upper floor side outward rail portion 71 and the inclined upper end portion 72c of the lower floor side outward rail portion 72 descend from the longitudinal inner edge at a predetermined inclination angle, It is cut in an inclined shape reaching the edge. Further, the inclined lower end portion 71c and the cut surface of the upper end portion 72c of the lower floor side forward rail portion 72 opposite to the inclined lower end portion 71c are inclined so as to abut (match) the inclined lower end portion 71c on the upper floor side. Is formed. The cutting direction of the outward rail 70 in the fourth embodiment is attached in a direction that spreads outward as seen from above the escalator 50, as with the cutting surface of the connecting member 10. FIG. 13 shows an example in which the end face (inner end portion 10 d) of the connecting member 10 is aligned with the inner side of the outward path rail 70 in the right and left outward path rails 70.

実施の形態４のエスカレータ５０の往路側レール７０は、この図１３のように構成され、レール接続部７６、又は、レール接続部７６のレール隙間７０Ｇから流れ落ちた油が、経路２７のように、レール同士を接続する接続部材１０の端面（外側端部１０ｃ）に沿って外側に流れ、その外側端部１０ｃからオイルパン１４へ流れ落ちる。このため、実施の形態４のエスカレータ５０は、ステップ２の踏板に油が付着しなくなり、ステップ２を清掃するといった手間を省くことができる。なお、左右のレールの傾斜角度は、実施の形態３と同様に、それぞれ異なっていてもよい。 The forward side rail 70 of the escalator 50 according to the fourth embodiment is configured as shown in FIG. 13, and the oil that has flowed down from the rail connection portion 76 or the rail clearance 70 G of the rail connection portion 76 is like the route 27. It flows outward along the end surface (outer end portion 10 c) of the connecting member 10 that connects the rails, and flows down from the outer end portion 10 c to the oil pan 14. For this reason, the escalator 50 according to the fourth embodiment can eliminate the trouble of cleaning the step 2 because the oil does not adhere to the tread in the step 2. Note that the inclination angles of the left and right rails may be different from each other as in the third embodiment.

実施の形態５．
図１４は、本発明の実施の形態５における往路側レールの接続部の油滴下構造の模式図である。実施の形態５のエスカレータ５０は、図１４に示すように、上方階側往路レール部７１の傾斜状の下端部７１ｃと下方階側往路レール部７２の傾斜状の上端部７２ｃとのレール接続部７６に、当該レール接続部７６から滴下する油１１を、床上のオイルパン１４に向かって滴下させる案内経路部（ドレーン１３）を設けたものである。Embodiment 5. FIG.
FIG. 14 is a schematic diagram of the oil dripping structure of the connecting portion of the forward path rail according to the fifth embodiment of the present invention. As shown in FIG. 14, the escalator 50 according to the fifth embodiment includes a rail connection portion between an inclined lower end portion 71 c of the upper floor side forward rail portion 71 and an inclined upper end portion 72 c of the lower floor side outward rail portion 72. 76 is provided with a guide path portion (drain 13) for dropping the oil 11 dripping from the rail connection portion 76 toward the oil pan 14 on the floor.

上述のように、レール接続部材１０の下端部１０ａを斜めにすることで、油１１の滴下する箇所が下端部１０ａの外側に集中するため、図１４では、案内経路部として、油１１の滴下箇所（往路側レール７０の外側）にドレーン１３を設けている。このドレーン１３によって油滴をオイルパン１４に直接流しているため、実施の形態５のエスカレータ５０は、オイルパン１４に落下した時のハネによる油の飛散を抑制できる。 As described above, since the lower end portion 10a of the rail connection member 10 is inclined, the locations where the oil 11 is dripped concentrate on the outside of the lower end portion 10a. Therefore, in FIG. A drain 13 is provided at a location (outside of the outward path rail 70). Since the oil droplets are caused to flow directly to the oil pan 14 by the drain 13, the escalator 50 according to the fifth embodiment can suppress the scattering of oil due to the splash when it falls on the oil pan 14.

なお、ドレーン１３は、実施の形態１〜４の往路側レール７０のレール接続部７６においても設置できる。 In addition, the drain 13 can be installed also in the rail connection part 76 of the outward path side rail 70 of Embodiment 1-4.

実施の形態６．
図１５は、本発明の実施の形態６における往路側レールの接続部の油滴下構造の模式図である。図１６は、図１５の油滴下構造の油の流れを説明する図である。実施の形態６のエスカレータ５０は、図１５、図１６に示すように、上方階側往路レール部７１の傾斜状の下端部７１ｃと下方階側往路レール部７２の傾斜状の上端部７２ｃとのレール接続部７６に、当該レール接続部７６から滴下する油１１を、帰路側レール８０上を走行する駆動ローラ５の帰路側チェーン８５に向かって滴下させる案内経路部（プレート１５）を設けたものである。実施の形態６では、図１５、図１６に示すように、例えば往路側レール７０に固定したプレート１５を設けた。プレート１５は、レール接続部７６から流れて鉛直下向きに落ちた油１１がプレート１５に直接当たる位置である往路側レール７０のレール接続部７６の下側の部分に設置する。図１６では、プレート１５が往路側レール７０に垂直に配置された例を示した。Embodiment 6 FIG.
FIG. 15 is a schematic diagram of the oil dripping structure of the connecting portion of the forward path rail according to the sixth embodiment of the present invention. FIG. 16 is a diagram for explaining the flow of oil in the oil dripping structure of FIG. 15. As shown in FIGS. 15 and 16, the escalator 50 according to the sixth embodiment includes an inclined lower end 71 c of the upper floor side forward rail portion 71 and an inclined upper end portion 72 c of the lower floor side forward rail portion 72. The rail connection portion 76 is provided with a guide path portion (plate 15) for dropping the oil 11 dripping from the rail connection portion 76 toward the return-side chain 85 of the drive roller 5 traveling on the return-side rail 80. It is. In the sixth embodiment, as shown in FIGS. 15 and 16, for example, the plate 15 fixed to the forward path rail 70 is provided. The plate 15 is installed in a lower portion of the rail connection portion 76 of the forward path side rail 70 at a position where the oil 11 that flows from the rail connection portion 76 and falls vertically downward directly hits the plate 15. In FIG. 16, an example in which the plate 15 is arranged perpendicular to the forward path side rail 70 is shown.

プレート１５は、図１５、図１６のように帰路側チェーン８５の直上に配置され、下方端部を二股形状にした二股部１５ｃを備えている。二股部１５ｃは、凸部１５ａ及び凸部１５ｂを有し、その凸部１５ａ、凸部１５ｂを帰路側チェーン８５の直上に配置させる。この配置によって、往路側レール７０のレール接続部７６から流れて鉛直下向きに落ちた油１１は、プレート１５に直接当たり、その後に二股部１５ｃの方へ流れ、プレート１５の二股部１５ｃの凸部１５ａ、凸部１５ｂを伝って、それぞれの帰路側チェーン８５の直上へ滴下する。実施の形態６のエスカレータ５０は、プレート１５により、往路側レール７０のレール接続部７６から流れて鉛直下向きに落ちた油１１を、それぞれの帰路側チェーン８５の直上へ滴下させることができ、駆動ローラ５が付いた帰路側チェーン８５を潤滑できる。 As shown in FIGS. 15 and 16, the plate 15 is disposed immediately above the return-side chain 85, and includes a bifurcated portion 15 c having a bifurcated lower end portion. The bifurcated portion 15 c has a convex portion 15 a and a convex portion 15 b, and the convex portion 15 a and the convex portion 15 b are arranged immediately above the return path side chain 85. With this arrangement, the oil 11 that has flowed from the rail connecting portion 76 of the forward rail 70 and dropped vertically downward directly hits the plate 15 and then flows toward the bifurcated portion 15c, and the convex portion of the bifurcated portion 15c of the plate 15 15a and the convex part 15b are dripped directly on the respective return side chains 85. The escalator 50 according to the sixth embodiment can drop the oil 11 that has flowed from the rail connecting portion 76 of the forward-side rail 70 and dropped vertically downward by the plate 15 onto each return-side chain 85 and is driven. The return side chain 85 with the roller 5 can be lubricated.

実施の形態６のエスカレータ５０は、図１５の案内経路部（プレート１５）を備え、案内経路部（プレート１５）がレール接続部７６から流れて鉛直下向きに落ちた油１１がプレート１５に直接当たる位置である往路側レール７０のレール接続部７６の下側の部分に設置されたエスカレータである。従来の案内経路部では、往路側で流れた油は、オイルパン等に滴下し廃液となっていた。これに対して、実施の形態６のエスカレータ５０は、往路側で流れた油１１が帰路側チェーン８５に滴下するため、流れた油１１を帰路側チェーン８５の潤滑に再利用でき、全体の油の滴下量を減らすことができる。又、実施の形態６のエスカレータ５０は、案内経路部（プレート１５）をレール接続部７６から流れて鉛直下向きに落ちた油１１が直接当たる位置である往路側レール７０のレール接続部７６の下側の部分に設置することで、流れ落ちた油１１を帰路側チェーン８５の潤滑に再利用できるため、図１４のドレーン１３を削減することができる。 The escalator 50 of the sixth embodiment includes the guide path portion (plate 15) of FIG. 15, and the oil 11 that has flowed down from the rail connection portion 76 and has fallen vertically downward directly hits the plate 15. It is an escalator installed in the lower part of the rail connection part 76 of the forward path side rail 70 which is a position. In the conventional guide path portion, the oil that has flowed on the outward path is dropped into an oil pan or the like to become a waste liquid. On the other hand, the escalator 50 according to the sixth embodiment allows the oil 11 that has flowed on the forward path to drip on the return chain 85, so that the oil 11 that has flowed can be reused for lubrication of the return chain 85. The amount of dripping can be reduced. Further, the escalator 50 according to the sixth embodiment is provided under the rail connection portion 76 of the forward rail 70 where the oil 11 that has flowed from the rail connection portion 76 and dropped in the vertical downward direction directly hits the guide path portion (plate 15). Since the oil 11 that has flowed down can be reused for lubrication of the return side chain 85 by installing it in the side portion, the drain 13 in FIG. 14 can be reduced.

又、案内経路部に図１４のドレーン１３と図１５のプレート１５を併用しても良い。図１５のプレート１５を、往路側レール７０のレール接続部７６の上側の部分に設置し、レール接続部７６に図１４のドレーン１３を配置するようにすることで、このように構成された実施の形態５のエスカレータ５０は、オイルパン１４に油が落ちにくくなるため、オイルパン１４の清掃作業を減らすことができる。 Further, the drain 13 of FIG. 14 and the plate 15 of FIG. The plate 15 of FIG. 15 is installed in the upper part of the rail connection portion 76 of the outward rail 70, and the drain 13 of FIG. Since the escalator 50 according to the fifth aspect makes it difficult for oil to fall into the oil pan 14, the cleaning operation of the oil pan 14 can be reduced.

実施の形態７．
図１７は発明の実施の形態７による往路側レールの接続部を示す図であり、図１８は図１７の往路側レールの接続部の断面図である。実施の形態７のエスカレータ５０は、図１７、図１８に示すように、レール接続部材１０の幅方向の長さを往路側レール７０のレール内側面７７と同一もしくは往路側レール７０のレール内側面７７より内側に配置することで、すなわち、レール接続部材１０の内側端部１０ｄがレール内側面７７と同一もしくはレール内側面７７よりも内側に飛び出るようにしたものである。このようにすることで、実施の形態７のエスカレータ５０は、チェーン２０に給油された油が全て往路側レール７０の内側を伝って流れた場合でも、レール接続部７６にて駆動ローラ走行部７０Ａの外側へ流れ落ち、ステップ２への油の滴下を阻止することができる。Embodiment 7 FIG.
17 is a view showing a connecting portion of the forward rail according to the seventh embodiment of the invention, and FIG. 18 is a cross-sectional view of the connecting portion of the outward rail in FIG. As shown in FIGS. 17 and 18, the escalator 50 according to the seventh embodiment has the same length in the width direction of the rail connecting member 10 as the rail inner side surface 77 of the forward path side rail 70 or the rail inner side surface of the forward path side rail 70. In other words, the inner end portion 10d of the rail connection member 10 is the same as the rail inner side surface 77 or protrudes inward from the rail inner side surface 77. By doing in this way, the escalator 50 of the seventh embodiment allows the driving roller traveling portion 70 A at the rail connecting portion 76 even when all of the oil supplied to the chain 20 flows along the inside of the forward path side rail 70. It is possible to prevent the oil from dripping to Step 2.

具体的には、往路側レール７０の組付けの際に、往路側レール７０をエスカレータ５０の内側の方が低く組付けた場合、チェーン２０に給油された油は往路側レール７０の内側端を伝う。その際、下方階側の切断形状が、エスカレータ５０の上方から見て下方に向かって外側に広がる方向に切断されたレール接続部材１０を、図１７、図１８のようにレール内側面７７と同一もしくはレール内側面７７よりも内側に飛び出させることで、図１７の経路２５のように油が流れる。経路２５のようにレール内側面７７を伝った油は、レール接続部材１０の内側端部１０ｄを流れ、その後レール接続部材１０における外側に傾斜した傾斜状の下端部１０ａに沿って油が外側に流れ落ちるため、実施の形態７のエスカレータ５０はステップ２への油の滴下を阻止することができる。 Specifically, when the forward rail 70 is assembled at the lower side of the escalator 50 when the forward rail 70 is assembled, the oil supplied to the chain 20 moves the inner end of the forward rail 70. Communicate. At that time, the rail connecting member 10 whose cutting shape on the lower floor side is cut in a direction that spreads outward as seen from above the escalator 50 is the same as the rail inner surface 77 as shown in FIGS. Alternatively, the oil flows out from the rail inner side surface 77 as shown in the path 25 of FIG. The oil that has traveled along the rail inner surface 77 as in the path 25 flows through the inner end portion 10d of the rail connection member 10, and then the oil moves outward along the inclined lower end portion 10a that is inclined outward in the rail connection member 10. Since it flows down, the escalator 50 according to the seventh embodiment can prevent the oil from dropping to the step 2.

また、発明の実施の形態７による往路側レールの接続構造は、他の構造でもよい。図１９は本発明の実施の形態７による他の往路側レールの接続部を示す図であり、図２０は図１９の往路側レールの接続部の断面図である。図２１は、図１９の往路側レールと帰路側レールの相対位置を示す模式図である。図１９では、レール接続部材１０が、レール内側面７７よりも内側に飛び出し、かつレール外側面７８よりも外側に飛び出した例を示した。この場合、往路側レール７０を伝った油は、レール接続部材１０における外側に傾斜した傾斜状の下端部１０ａに沿って油が外側に流れ、レール接続部材１０の下端部１０ａにおける外側端部１０ｃから直接オイルパン１４に滴下できる。このため、図１９に示したレール接続部材１０を有する実施の形態７のエスカレータ５０はステップ２への油の滴下を阻止することができる。また、図１９に示したレール接続部材１０を有する実施の形態７のエスカレータ５０は、チェーン２０に油を滴下した際にも、往路側レール７０を伝った油が直接オイルパン１４に滴下するので、油の飛散をなくすことができる。なお、レール接続部材１０の外側端部１０ｃは、少なくも下端部１０ａの側において往路側レール７０のレール外側面７８よりも外側に飛び出していればよい。 Further, the forward rail connection structure according to the seventh embodiment of the invention may be another structure. FIG. 19 is a view showing another forward rail connection portion according to the seventh embodiment of the present invention, and FIG. 20 is a cross-sectional view of the forward rail connection portion of FIG. FIG. 21 is a schematic diagram showing the relative positions of the forward path rail and the return path rail in FIG. FIG. 19 shows an example in which the rail connecting member 10 protrudes inward from the rail inner surface 77 and protrudes outward from the rail outer surface 78. In this case, the oil that has traveled along the forward rail 70 flows outward along the inclined lower end portion 10 a that is inclined outward in the rail connection member 10, and the outer end portion 10 c in the lower end portion 10 a of the rail connection member 10. Can be dripped directly into the oil pan 14. For this reason, the escalator 50 of Embodiment 7 which has the rail connection member 10 shown in FIG. 19 can prevent the dripping of the oil to Step 2. FIG. Further, in the escalator 50 according to the seventh embodiment having the rail connecting member 10 shown in FIG. 19, even when oil is dropped on the chain 20, the oil that has traveled on the forward rail 70 drops directly on the oil pan 14. , Oil splashing can be eliminated. The outer end portion 10c of the rail connecting member 10 only needs to protrude outward from the rail outer surface 78 of the forward path side rail 70 at least on the lower end portion 10a side.
