実施の形態１．
図１は、マンコンベアの全体構成を示す断面図である。図１は、マンコンベアの一例として、上下階床間の移動の際に利用されるエスカレータを示す。動く歩道といったマンコンベアの他の例については、具体的な説明を省略する。 Embodiment 1 FIG.
FIG. 1 is a cross-sectional view showing the overall configuration of the man conveyor. FIG. 1 shows an escalator used when moving between upper and lower floors as an example of a man conveyor. A concrete description of other examples of the man conveyor such as a moving sidewalk is omitted.

エスカレータの乗客は、上下階床間を移動する際にステップ１に乗る。ステップ１は、上部の乗降口２から下部の乗降口３に渡って隙間無く配置される。ステップ１は、機械室４に設けられた電動機５によって駆動され、乗降口２及び３間を循環移動する。電動機５は、機械室４に設けられた制御盤６によって制御される。   Escalator passengers take step 1 as they move between the upper and lower floors. Step 1 is arranged without a gap from the upper entrance 2 to the lower entrance 3. Step 1 is driven by an electric motor 5 provided in the machine room 4 and circulates between the entrances 2 and 3. The electric motor 5 is controlled by a control panel 6 provided in the machine room 4.

ステップ１に乗降する乗客及びステップ１に乗っている乗客は、安全のために移動手摺７を掴む。移動手摺７は、ガイド装置によって移動（走行）が案内される。ガイド装置は、例えば欄干８の縁部に設けられる。欄干８は、ステップ１の両側に配置される。欄干８は、例えばガラスパネルからなる。   Passengers getting on and off step 1 and passengers on step 1 grab the moving handrail 7 for safety. Movement (running) of the moving handrail 7 is guided by the guide device. The guide device is provided at the edge of the balustrade 8, for example. The balustrade 8 is arranged on both sides of the step 1. The balustrade 8 is made of, for example, a glass panel.

移動手摺７は、無端状を呈する。移動手摺７は、乗降口２及び３で上下に反転され、欄干８を周回するように移動する。移動手摺７は、手摺駆動装置９によって駆動される。手摺駆動装置９は、ステップ１と同期するように移動手摺７を移動させる。   The moving handrail 7 has an endless shape. The moving handrail 7 is reversed up and down at the entrances 2 and 3 and moves around the rail 8. The moving handrail 7 is driven by a handrail driving device 9. The handrail driving device 9 moves the moving handrail 7 so as to synchronize with Step 1.

移動手摺７は無端状を呈するため、移動手摺７には接合部分が存在する。即ち、無端状の移動手摺７を得るためには、先ず、長尺の手摺本体を製作する。次に、手摺本体を所望の長さに切断し、手摺本体の端部同士を接合する。これにより、無端状の移動手摺７を得ることができる。   Since the moving handrail 7 has an endless shape, the moving handrail 7 has a joint portion. That is, in order to obtain the endless moving handrail 7, first, a long handrail body is manufactured. Next, the handrail body is cut into a desired length, and the ends of the handrail body are joined together. Thereby, the endless moving handrail 7 can be obtained.

A transverse section is a section in a direction orthogonal to the longitudinal direction of the moving handrail 7. The moving handrail 7 includes, for example, a main body resin portion 10, a tensile body 11, and a canvas 12. The moving handrail 7 further includes a reinforcing cloth 13 at the joint portion.

本体樹脂部１０は、移動手摺７の要部を構成する。本体樹脂部１０は、例えばゴム或いはポリウレタン等の樹脂部材からなる。本体樹脂部１０は、全体として無端状に形成される。本体樹脂部１０は、横断面が略Ｃ字状を呈する。図３及び図４は、本体樹脂部１０が２層の樹脂層によって構成される例を示す。移動手摺７に付与する機能に合わせて、本体樹脂部１０を単層或いは３層以上の樹脂層で構成しても良い。   The main body resin part 10 constitutes a main part of the moving handrail 7. The main body resin portion 10 is made of a resin member such as rubber or polyurethane. The main body resin portion 10 is formed in an endless shape as a whole. The main body resin portion 10 has a substantially C-shaped cross section. 3 and 4 show an example in which the main body resin portion 10 is composed of two resin layers. The main body resin portion 10 may be composed of a single layer or three or more resin layers according to the function to be given to the moving handrail 7.

抗張体１１は、移動手摺７に一定の引張強度を付与するために備えられる。抗張体１１は、例えば鋼製のワイヤが縒り合わされたものからなる。スチールテープ等によって抗張体１１を構成しても良い。抗張体１１は、本体樹脂部１０の内部に設けられる。図３及び図４は、１５本の抗張体１１が並べて配置される例を示す。移動手摺７が備える抗張体１１の本数は、図３及び図４に示す例に限定されない。抗張体１１は、本体樹脂部１０の長手に沿って本体樹脂部１０の全長に渡って配置される。   The tensile body 11 is provided to give the moving handrail 7 a certain tensile strength. The tensile body 11 is made of, for example, a wire made of steel. The tensile body 11 may be made of steel tape or the like. The tensile body 11 is provided inside the main body resin portion 10. 3 and 4 show an example in which 15 tensile bodies 11 are arranged side by side. The number of the tension bodies 11 included in the moving handrail 7 is not limited to the examples illustrated in FIGS. 3 and 4. The tensile body 11 is disposed over the entire length of the main body resin portion 10 along the length of the main body resin portion 10.

帆布１２は、移動手摺７の走行抵抗を低減させるために備えられる。帆布１２は、本体樹脂部１０の内側の表面に設けられる。本体樹脂部１０の外側の表面は、把持面を形成する。把持面は、乗客の手が触れる可能性がある面である。帆布１２は、本体樹脂部１０の長手に沿って本体樹脂部１０の全長に渡って配置される。帆布１２は、例えば樹脂繊維を用いて織られた織物からなる。   The canvas 12 is provided to reduce the running resistance of the moving handrail 7. The canvas 12 is provided on the inner surface of the main body resin portion 10. The outer surface of the main body resin portion 10 forms a gripping surface. The grip surface is a surface that may be touched by the passenger's hand. The canvas 12 is disposed over the entire length of the main body resin portion 10 along the length of the main body resin portion 10. The canvas 12 is made of, for example, a fabric woven using resin fibers.

補強布１３は、移動手摺７の接続部分においてレール保持部１４を補強するために備えられる。図３及び図４に示すように、移動手摺７にはレール保持部１４が形成される。移動手摺７を横断面で見ると、移動手摺７には抗張体１１が配置される平坦な部分とこの平坦な部分の両側でＵ字状に湾曲する部分とがある。Ｕ字状に湾曲する部分は、ガイド装置のレールの縁を囲むように配置される。レール保持部１４は、このＵ字状に湾曲する部分のうち、レールの側方から裏側に配置される部分である。図４の破線Ｃで囲まれた部分がレール保持部１４に該当する。レール保持部１４は、移動手摺７の長手に沿って配置される。   The reinforcing cloth 13 is provided to reinforce the rail holding portion 14 at the connection portion of the moving handrail 7. As shown in FIGS. 3 and 4, a rail holding portion 14 is formed on the moving handrail 7. When the moving handrail 7 is viewed in a cross section, the moving handrail 7 has a flat portion where the tensile body 11 is disposed and a portion that is curved in a U shape on both sides of the flat portion. The U-shaped curved portion is arranged so as to surround the edge of the guide device rail. The rail holding part 14 is a part arrange | positioned from the side of a rail to the back side among the parts curved in this U shape. A portion surrounded by a broken line C in FIG. 4 corresponds to the rail holding portion 14. The rail holding portion 14 is disposed along the length of the moving handrail 7.

補強布１３は、例えば樹脂繊維を用いて織られた織物からなる。補強布１３は、移動手摺７の接続部分のレール保持部１４に設けられる。移動手摺７の接合部分ではない部分に補強布１３は設けられていない。補強布１３は、本体樹脂部１０の内部に設けられる。図２は、一方のレール保持部１４に設けられた補強布１３と他方のレール保持部１４に設けられた補強布１３とが移動手摺７の長手方向にずれて配置された例を示す。   The reinforcing cloth 13 is made of a woven fabric woven using, for example, resin fibers. The reinforcing cloth 13 is provided on the rail holding portion 14 at the connection portion of the moving handrail 7. The reinforcing cloth 13 is not provided in a portion that is not a joining portion of the moving handrail 7. The reinforcing cloth 13 is provided inside the main body resin portion 10. FIG. 2 shows an example in which the reinforcing cloth 13 provided on one rail holding part 14 and the reinforcing cloth 13 provided on the other rail holding part 14 are arranged shifted in the longitudinal direction of the moving handrail 7.

以下に、図５から図１０も参照し、移動手摺７を製造する方法について説明する。図５は、移動手摺７の製造方法を説明するための図である。   Hereinafter, a method for manufacturing the moving handrail 7 will be described with reference to FIGS. FIG. 5 is a diagram for explaining a method of manufacturing the moving handrail 7.

先ず、押し出し成型等によって長尺の手摺本体１５を製作する。手摺本体１５の断面は、図４に示す断面と同様である。即ち、手摺本体１５は、横断面が略Ｃ字状を呈する。手摺本体１５は、例えば本体樹脂部１０、抗張体１１及び帆布１２を備える。   First, the long handrail main body 15 is manufactured by extrusion molding or the like. The cross section of the handrail main body 15 is the same as that shown in FIG. That is, the handrail main body 15 has a substantially C-shaped cross section. The handrail main body 15 includes, for example, a main body resin portion 10, a tensile body 11, and a canvas 12.

次に、手摺本体１５を所望の長さに切断し、手摺本体１５の端部１５ａ及び１５ｂ同士を接合する。図５は、端部１５ａと端部１５ｂとを対向させた接合前の状態を示す。図６は、図５に示す手摺本体１５をＤ方向から見た図である。図７は、図５のＥ−Ｅ断面を示す図である。図５は、手摺本体１５を斜めに直線状に切断する例を示す。移動手摺７の接合部分において抗張体１１が重なり合うように、端部１５ａ及び端部１５ｂに段差を形成しても良い。   Next, the handrail main body 15 is cut into a desired length, and the end portions 15a and 15b of the handrail main body 15 are joined to each other. FIG. 5 shows a state before joining with the end 15a and the end 15b facing each other. FIG. 6 is a view of the handrail main body 15 shown in FIG. 5 as viewed from the D direction. FIG. 7 is a cross-sectional view taken along line EE in FIG. FIG. 5 shows an example in which the handrail body 15 is cut diagonally and linearly. A step may be formed at the end 15a and the end 15b so that the tensile bodies 11 overlap at the joint portion of the moving handrail 7.

端部１５ａと端部１５ｂとの接合に際しては、先ず、端部１５ａに切り欠き１６ａ及び１６ｂを形成する。切り欠き１６ａは、端部１５ａの一方のレール保持部１４に形成される。切り欠き１６ａは、端部１５ａの端面及びレール保持部１４の外側の表面で開口する。切り欠き１６ａの開口は一続きに形成される。切り欠き１６ａは、例えば、手摺本体１５の横断面においてレール保持部１４の先端部に向かって延びるように本体樹脂部１０に形成される。切り欠き１６ｂは、端部１５ａの他方のレール保持部１４に形成される。切り欠き１６ｂは、端部１５ａの端面及びレール保持部１４の外側の表面で開口する。切り欠き１６ｂの開口は一続きに形成される。切り欠き１６ｂは、例えば、手摺本体１５の横断面においてレール保持部１４の先端部に向かって延びるように本体樹脂部１０に形成される。   When joining the end 15a and the end 15b, first, notches 16a and 16b are formed in the end 15a. The notch 16a is formed in one rail holding portion 14 of the end portion 15a. The notch 16 a opens at the end surface of the end portion 15 a and the outer surface of the rail holding portion 14. The openings of the notches 16a are formed continuously. The notch 16a is formed in the main body resin portion 10 so as to extend toward the tip end portion of the rail holding portion 14 in the cross section of the handrail main body 15, for example. The notch 16b is formed in the other rail holding part 14 of the end part 15a. The notch 16 b opens at the end surface of the end 15 a and the outer surface of the rail holding portion 14. The openings of the notches 16b are formed continuously. The notch 16b is formed in the main body resin portion 10 so as to extend toward the tip end portion of the rail holding portion 14 in the cross section of the handrail main body 15, for example.

また、端部１５ｂに切り欠き１７ａ及び１７ｂを形成する。切り欠き１７ａは、端部１５ｂの一方のレール保持部１４に形成される。切り欠き１７ａは、端部１５ｂの端面及びレール保持部１４の外側の表面で開口する。切り欠き１７ａの開口は一続きに形成される。切り欠き１７ａは、例えば、手摺本体１５の横断面においてレール保持部１４の先端部に向かって延びるように本体樹脂部１０に形成される。切り欠き１７ｂは、端部１５ｂの他方のレール保持部１４に形成される。切り欠き１７ｂは、端部１５ｂの端面及びレール保持部１４の外側の表面で開口する。切り欠き１７ｂの開口は一続きに形成される。切り欠き１７ｂは、例えば、手摺本体１５の横断面においてレール保持部１４の先端部に向かって延びるように本体樹脂部１０に形成される。   Further, notches 17a and 17b are formed in the end portion 15b. The notch 17a is formed in one rail holding part 14 of the end part 15b. The notch 17 a opens at the end surface of the end portion 15 b and the outer surface of the rail holding portion 14. The opening of the notch 17a is formed continuously. The notch 17a is formed in the main body resin portion 10 so as to extend toward the tip end portion of the rail holding portion 14 in the cross section of the handrail main body 15, for example. The notch 17b is formed in the other rail holding part 14 of the end part 15b. The notch 17b opens at the end surface of the end portion 15b and the outer surface of the rail holding portion 14. The opening of the notch 17b is formed continuously. The notch 17b is formed in the main body resin portion 10 so as to extend toward the tip end portion of the rail holding portion 14 in the cross section of the handrail main body 15, for example.

端部１５ａに形成された切り欠き１６ａと端部１５ｂに形成された切り欠き１７ａとは、端部１５ａの端面と端部１５ｂの端面とを合わせると一続きに形成される。端部１５ａに形成された切り欠き１６ｂと端部１５ｂに形成された切り欠き１７ｂとは、端部１５ａの端面と端部１５ｂの端面とを合わせると一続きに形成される。   The notch 16a formed in the end 15a and the notch 17a formed in the end 15b are formed continuously when the end face of the end 15a and the end face of the end 15b are combined. The notch 16b formed in the end 15a and the notch 17b formed in the end 15b are formed continuously when the end face of the end 15a and the end face of the end 15b are combined.

端部１５ａと端部１５ｂとの接合に際しては、切り欠き１６ａ及び切り欠き１７ａを対向させることによって端部１５ａ及び端部１５ｂに形成された一続きの空間に補強布１３を配置する。また、切り欠き１６ｂ及び切り欠き１７ｂを対向させることによって端部１５ａ及び端部１５ｂに形成された一続きの空間に補強布１３を配置する。図８は、手摺本体１５の端部１５ａ及び端部１５ｂに形成された空間に補強布１３が挿入された状態を示す断面図である。そして、補強布１３を上記各空間に配置した状態で端部１５ａ及び端部１５ｂを成形型に配置し、加熱成型を行う。成形型に配置する際に、上記各空間を埋めるための追加樹脂部材を用いても良い。これにより、端部１５ａと端部１５ｂとを接合する。   When joining the end 15a and the end 15b, the reinforcing cloth 13 is disposed in a continuous space formed in the end 15a and the end 15b by making the notch 16a and the notch 17a face each other. Further, the reinforcing cloth 13 is arranged in a continuous space formed in the end 15a and the end 15b by making the notch 16b and the notch 17b face each other. FIG. 8 is a cross-sectional view showing a state in which the reinforcing cloth 13 is inserted into the space formed at the end 15a and the end 15b of the handrail main body 15. And the end part 15a and the end part 15b are arrange | positioned to a shaping | molding die in the state which has arrange | positioned the reinforcement cloth 13 in said each space, and it heat-molds. An additional resin member for filling each of the above-mentioned spaces may be used when arranging in the mold. Thereby, the edge part 15a and the edge part 15b are joined.

図９は、補強布１３を示す図である。補強布１３に関しては、樹脂を予め浸み込ませたものを用意しておく。成型時に加熱されることにより、補強布１３に浸み込ませた樹脂が溶融し、本体樹脂部１０を構成する樹脂と一体化する。補強布１３に予め浸み込ませておく樹脂は、本体樹脂部１０を構成する樹脂との接着性に優れたものが良い。例えば、本体樹脂部１０を構成する樹脂と同じ樹脂が好適である。   FIG. 9 is a view showing the reinforcing cloth 13. Regarding the reinforcing cloth 13, a resin cloth soaked in advance is prepared. By being heated at the time of molding, the resin soaked in the reinforcing cloth 13 is melted and integrated with the resin constituting the main body resin portion 10. The resin that is preliminarily soaked into the reinforcing cloth 13 is preferably excellent in adhesiveness with the resin constituting the main body resin portion 10. For example, the same resin as that constituting the main body resin portion 10 is suitable.

また、補強布１３に関しては、加熱成型が行われる前に予め熱処理が施されたものを用意しておくことが好ましい。例えば、本体樹脂部１０を構成する樹脂と同種の熱可塑性樹脂を溶融し、補強布１３に含ませても良い。予め熱処理が施された補強布１３を用いることにより、加熱成型時の補強布１３の収縮を抑制できる。これにより、加熱成型時に補強布１３がずれてしまうことを抑制できる。   In addition, regarding the reinforcing cloth 13, it is preferable to prepare a cloth that has been heat-treated in advance before heat molding. For example, the same kind of thermoplastic resin as that constituting the main body resin portion 10 may be melted and included in the reinforcing cloth 13. By using the reinforcing cloth 13 that has been heat-treated in advance, shrinkage of the reinforcing cloth 13 during heat molding can be suppressed. Thereby, it can control that reinforcing cloth 13 shifts at the time of heat forming.

上記手順により、図２及び図３に示す断面の移動手摺７を製造することができる。図１０は、図３のＦ−Ｆ断面を示す図である。図１０に示すように、補強布１３は、移動手摺７の接合部分においてレール保持部１４の内部に設けられる。例えば、移動手摺７が乗降口２及び乗降口３で上下に反転する時、抗張体１１を含む移動手摺７の平坦な部分には大きな応力は作用しない。応力は主にレール保持部１４に作用する。上記構成を有する移動手摺７であれば、補強布１３によってレール保持部１４の接合強度を十分に確保できる。樹脂を予め浸み込ませた補強布１３を用いることにより、補強布１３を本体樹脂部１０に一体化させることができる。   The moving handrail 7 having the cross section shown in FIGS. 2 and 3 can be manufactured by the above procedure. FIG. 10 is a diagram showing a cross section taken along line FF in FIG. 3. As shown in FIG. 10, the reinforcing cloth 13 is provided inside the rail holding portion 14 at the joint portion of the moving handrail 7. For example, when the moving handrail 7 is turned upside down at the entrance 2 and the entrance 3, no large stress acts on the flat portion of the moving handrail 7 including the tensile body 11. The stress mainly acts on the rail holding portion 14. If it is the moving handrail 7 which has the said structure, the joint strength of the rail holding | maintenance part 14 can fully be ensured by the reinforcement cloth 13. By using the reinforcing cloth 13 in which the resin is preliminarily immersed, the reinforcing cloth 13 can be integrated with the main body resin portion 10.

補強布１３は柔軟性に優れる。接合部分のレール保持部１４を補強する部材として金属製の部材等を用いていないため、レール保持部１４に十分な柔軟性を確保できる。接合部分のレール保持部１４をガイド装置のレールの湾曲に合わせて容易に変形させることができる。   The reinforcing cloth 13 is excellent in flexibility. Since a metal member or the like is not used as a member that reinforces the rail holding portion 14 at the joint portion, sufficient flexibility can be secured for the rail holding portion 14. The rail holding portion 14 at the joint portion can be easily deformed according to the curvature of the rail of the guide device.

図１０に示すように、補強布１３は移動手摺７の表面に露出しない。即ち、補強布１３は、移動手摺７の内側の表面に露出しない。移動手摺７がガイド装置のレールに接触することによって補強布１３が剥がれることはない。このため、移動手摺７の保守を容易に行うことができ、エスカレータの保守に要する手間及び時間を短縮できる。   As shown in FIG. 10, the reinforcing cloth 13 is not exposed on the surface of the moving handrail 7. That is, the reinforcing cloth 13 is not exposed on the inner surface of the moving handrail 7. The reinforcing cloth 13 is not peeled off when the moving handrail 7 contacts the rail of the guide device. For this reason, the maintenance of the moving handrail 7 can be easily performed, and the labor and time required for the maintenance of the escalator can be shortened.

なお、移動手摺７の接合部分では、図１０に示すように帆布１２の端が本体樹脂部１０側に押し込まれる。そして、帆布１２の両端を覆うように留め樹脂１８が充填される。これにより、帆布１２が剥がれることを防止する。   In addition, in the junction part of the moving handrail 7, as shown in FIG. 10, the edge of the canvas 12 is pushed into the main body resin part 10 side. Then, the fastening resin 18 is filled so as to cover both ends of the canvas 12. This prevents the canvas 12 from peeling off.

図１１は、移動手摺７を製造する他の方法を説明するための図である。手摺本体１５の端部１５ａ及び端部１５ｂに形成された空間に補強布１３を配置する際に、図１１に示すように、本体樹脂部１０の横断面において帆布１２に沿うように補強布１３を配置しても良い。補強布１３を帆布１２に沿うように配置することにより、レール保持部１４の接合強度を更に向上させることができる。   FIG. 11 is a diagram for explaining another method of manufacturing the moving handrail 7. When the reinforcing cloth 13 is disposed in the space formed in the end portion 15a and the end portion 15b of the handrail main body 15, the reinforcing cloth 13 extends along the canvas 12 in the cross section of the main body resin portion 10 as shown in FIG. May be arranged. By arranging the reinforcing cloth 13 along the canvas 12, the bonding strength of the rail holding portion 14 can be further improved.
