特許文献１に記載された移動手摺は、抗張体が一枚の板状部材であるため、柔軟性に欠けるという問題があった。   The moving handrail described in Patent Document 1 has a problem that it lacks flexibility because the tensile body is a single plate-like member.

特許文献２に記載された移動手摺のように、複数のワイヤが縒り合わされた抗張体を使用すれば、移動手摺に所望の柔軟性を持たせることができる。しかし、特許文献２に記載された移動手摺では、移動手摺の長期使用によってワイヤが切れると、切れたワイヤが移動手摺の表面から飛び出すといった問題があった。   If a tensile body in which a plurality of wires are wound together is used like the moving handrail described in Patent Document 2, the moving handrail can have a desired flexibility. However, the moving handrail described in Patent Document 2 has a problem that when the wire is cut by long-term use of the moving handrail, the cut wire jumps out from the surface of the moving handrail.

この発明は、上述のような課題を解決するためになされた。この発明の目的は、切れたワイヤが把持面から飛び出すことを抑制できるマンコンベアの移動手摺を提供することである。   The present invention has been made to solve the above-described problems. The objective of this invention is providing the moving handrail of the man conveyor which can suppress that the cut wire jumps out of a holding surface.

この発明に係るマンコンベアの移動手摺は、無端状に形成された本体樹脂部と、本体樹脂部の表面に、本体樹脂部の長手に沿って設けられた帆布と、本体樹脂部の内部に、本体樹脂部の長手に沿って設けられた抗張体と、本体樹脂部の内部に本体樹脂部の長手に沿って設けられ、本体樹脂部の全長に渡って配置された金属製の遮蔽体と、を備える。抗張体は、ワイヤを含み、遮蔽体と帆布との間に配置される。遮蔽体は、帆布の反対側から抗張体を覆う。   The handrail of the man conveyor according to the present invention has an endless main body resin portion, a canvas provided along the length of the main body resin portion on the surface of the main body resin portion, and inside the main body resin portion. A tensile body provided along the length of the main body resin portion; and a metal shield provided along the length of the main body resin portion inside the main body resin portion and disposed over the entire length of the main body resin portion; . The tensile body includes a wire and is disposed between the shield and the canvas. The shield covers the tensile body from the opposite side of the canvas.

この発明に係るマンコンベアの移動手摺であれば、切れたワイヤが把持面から飛び出すことを抑制できる。   If it is the moving handrail of the man conveyor which concerns on this invention, it can suppress that the cut wire jumps out of a holding surface.

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、欄干８を周回するように移動する。移動手摺７は、乗降口２及び３で上下に反転される。移動手摺７は、一周移動する間に各所において湾曲される。   The moving handrail 7 has an endless shape. The moving handrail 7 moves so as to go around the balustrade 8. The moving handrail 7 is inverted up and down at the entrances 2 and 3. The moving handrail 7 is curved at various points while moving around.

移動手摺７は、手摺駆動装置９によって駆動される。摩擦駆動方式を採用する手摺駆動装置９は、例えば駆動ローラ及び加圧ローラを備える。手摺駆動装置９は、駆動ローラ及び加圧ローラによって移動手摺７を挟み込んだ状態で駆動ローラを回転させる。これにより、手摺駆動装置９は、移動手摺７との摩擦力を利用して移動手摺７を駆動する。移動手摺７は、ステップ１と同期するように移動する。移動手摺７は、移動中に駆動ローラ及び加圧ローラから常に力を受ける。   The moving handrail 7 is driven by a handrail driving device 9. The handrail drive device 9 adopting the friction drive system includes, for example, a drive roller and a pressure roller. The handrail driving device 9 rotates the driving roller in a state where the moving handrail 7 is sandwiched between the driving roller and the pressure roller. Thereby, the handrail driving device 9 drives the moving handrail 7 using the frictional force with the moving handrail 7. The moving handrail 7 moves so as to synchronize with step 1. The moving handrail 7 always receives force from the driving roller and the pressure roller during movement.

図２は、この発明の実施の形態１における移動手摺７の断面図である。図２は、移動手摺７を図１のＡ方向から見た断面を示す。図２に示すように、移動手摺７は横断面が略Ｃ字状を呈する。横断面とは、移動手摺７の長手の方向に直交する方向の断面である。移動手摺７は、例えば本体樹脂部１０、帆布１１、抗張体１２及び遮蔽体１３を備える。   FIG. 2 is a cross-sectional view of moving handrail 7 in the first embodiment of the present invention. FIG. 2 shows a cross section of the moving handrail 7 as seen from the direction A in FIG. As shown in FIG. 2, the moving handrail 7 has a substantially C-shaped cross section. 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 canvas 11, a tensile body 12, and a shielding body 13.

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２は、本体樹脂部１０が一種類の樹脂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を複数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. FIG. 2 shows an example in which the main body resin portion 10 is made of one kind of resin. The main body resin portion 10 may be composed of a plurality of resin layers in accordance with the function to be given to the moving handrail 7.

帆布１１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１１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。帆布１１は、例えば樹脂繊維を用いて織られた織物からなる。   The canvas 11 is provided to reduce the running resistance of the moving handrail 7. The canvas 11 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 11 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 11 is made of, for example, a fabric woven using resin fibers.

抗張体１２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１２は、本体樹脂部１０の内部に設けられる。図２は、１２本の抗張体１２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１２の本数は、図２に示す例に限定されない。抗張体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。   The tensile body 12 is provided to give the moving handrail 7 a certain tensile strength. The tensile body 12 is provided inside the main body resin portion 10. FIG. 2 shows an example in which twelve tensile bodies 12 are arranged side by side. The number of the tensile bodies 12 included in the moving handrail 7 is not limited to the example shown in FIG. The tensile body 12 is disposed over the entire length of the main body resin portion 10 along the length of the main body resin portion 10.

図３は、抗張体１２の断面を示す図である。抗張体１２は、例えば芯材１４及び子縄１５を備える。図３は、６本の子縄１５が芯材１４の周囲に巻き付けられる例を示す。抗張体１２の具体的な断面形状は、図３に示す例に限定されない。子縄１５は、例えば鋼製の複数のワイヤが縒り合わされて形成される。芯材１４は、例えば鋼製の複数のワイヤが縒り合わされて形成される。樹脂製或いは繊維製の芯材１４を用いても良い。   FIG. 3 is a view showing a cross section of the tensile body 12. The tensile body 12 includes, for example, a core member 14 and a strand 15. FIG. 3 shows an example in which six strands 15 are wound around the core material 14. The specific cross-sectional shape of the tensile body 12 is not limited to the example shown in FIG. The lasso 15 is formed by twisting a plurality of steel wires, for example. The core material 14 is formed by, for example, twisting a plurality of wires made of steel. A resin or fiber core 14 may be used.

遮蔽体１３は、抗張体１２を構成するワイヤが移動手摺７の把持面から飛び出すことを抑制するために備えられる。遮蔽体１３は、金属製の部材からなる。遮蔽体１３は、本体樹脂部１０の内部に設けられる。遮蔽体１３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。遮蔽体１３は、帆布１１の反対側から抗張体１２を覆うように配置される。抗張体１２は、遮蔽体１３と帆布１１の間に配置される。図２に示す横断面において、遮蔽体の両側の縁部１３ａは、一番外側に配置された抗張体１２より更に側方に突出するように配置される。   The shield 13 is provided to suppress the wire constituting the tensile body 12 from jumping out from the grip surface of the movable handrail 7. The shield 13 is made of a metal member. The shield 13 is provided inside the main body resin portion 10. The shield 13 is disposed along the length of the main body resin portion 10 over the entire length of the main body resin portion 10. The shield 13 is arranged so as to cover the tensile body 12 from the opposite side of the canvas 11. The tensile body 12 is disposed between the shield 13 and the canvas 11. In the cross section shown in FIG. 2, the edge portions 13 a on both sides of the shielding body are arranged so as to protrude further to the side than the tensile body 12 arranged on the outermost side.

図２は、移動手摺７の横断面において、遮蔽体１３が一枚の板状の部材からなる例を示す。図２に示すように、遮蔽体１３の縁部１３ａを帆布１１側に折り曲げても良い。   FIG. 2 shows an example in which the shield 13 is made of a single plate-like member in the cross section of the moving handrail 7. As shown in FIG. 2, the edge 13a of the shield 13 may be bent toward the canvas 11 side.

上述したように、移動手摺７は、移動する間に各所において湾曲される。また、移動手摺７は、移動中に駆動ローラ及び加圧ローラから常に力を受ける。上記湾曲及び加圧が長期に渡って繰り返されると、抗張体１２を構成するワイヤが切れてしまうことがある。ワイヤが切れた後も上記湾曲及び加圧は繰り返し行われる。これにより、切れたワイヤが本体樹脂部１０の内部で少しずつ移動する。   As described above, the moving handrail 7 is curved at various points while moving. Moreover, the moving handrail 7 always receives force from the driving roller and the pressure roller during movement. If the bending and pressurization are repeated over a long period of time, the wire constituting the tensile body 12 may be cut. Even after the wire is cut, the bending and pressurization are repeated. Thereby, the broken wire moves little by little inside the main body resin portion 10.

上記構成を有する移動手摺７であれば、切れたワイヤの移動を遮蔽体１３によって阻害することができる。このため、切れたワイヤが移動手摺７の把持面から飛び出すことを防止できる。遮蔽体１３は、切れたワイヤが当たっても簡単に破れないことが好ましい。遮蔽体１３として、例えばステンレス材或いは焼き入れ処理が施された鋼製の部材を採用することが好適である。   If it is the moving handrail 7 which has the said structure, the movement of the cut wire can be inhibited by the shielding body 13. FIG. For this reason, it can prevent that the cut wire jumps out from the holding surface of the moving handrail 7. It is preferable that the shield 13 is not easily broken even if a broken wire hits it. As the shield 13, it is preferable to employ, for example, a stainless steel member or a steel member that has been subjected to a quenching process.

上記構成を有する移動手摺７では、抗張体１２によって所望の引張強度が付与される。遮蔽体１３が抗張体１２の機能を備える必要はない。遮蔽体１３として薄い部材を使用することができる。このため、移動手摺７に必要な柔軟性が遮蔽体１３によって損なわれることはない。   In the moving handrail 7 having the above configuration, a desired tensile strength is imparted by the tensile body 12. The shield 13 need not have the function of the tensile body 12. A thin member can be used as the shield 13. For this reason, the flexibility required for the moving handrail 7 is not impaired by the shield 13.

図４は、移動手摺７の他の例を示す断面図である。図４に示す移動手摺７では、遮蔽体１３が複数の板状の部材を備える。図４に示す移動手摺７の他の構成は、図２に示す移動手摺７の構成と同じである。   FIG. 4 is a cross-sectional view showing another example of the moving handrail 7. In the moving handrail 7 shown in FIG. 4, the shield 13 includes a plurality of plate-like members. The other structure of the moving handrail 7 shown in FIG. 4 is the same as the structure of the moving handrail 7 shown in FIG.

図４は、遮蔽体１３が５枚の板状部材１６ａ〜１６ｅを備える例を示す。遮蔽体１３が備える板状部材の枚数は、図４に示す例に限定されない。板状部材１６ａ〜１６ｅは、移動手摺７の横断面において、一部が重なり合うように配置される。即ち、中央の板状部材１６ａは、図４において左側の縁部が板状部材１６ｂの右側の縁部に重なる。板状部材１６ａの右側の縁部は板状部材１６ｃの左側の縁部に重なる。板状部材１６ｂの左側の縁部は板状部材１６ｄの右側の縁部に重なる。板状部材１６ｃの右側の縁部は板状部材１６ｅの左側の縁部に重なる。板状部材１６ｄの左側の縁部は、例えば帆布１１側に折り曲げられる。板状部材１６ｅの右側の縁部は、例えば帆布１１側に折り曲げられる。   FIG. 4 shows an example in which the shield 13 includes five plate-like members 16a to 16e. The number of plate-like members provided in the shield 13 is not limited to the example shown in FIG. The plate-like members 16 a to 16 e are arranged so as to partially overlap in the cross section of the moving handrail 7. In other words, the left edge of the central plate member 16a in FIG. 4 overlaps the right edge of the plate member 16b. The right edge of the plate member 16a overlaps the left edge of the plate member 16c. The left edge of the plate member 16b overlaps the right edge of the plate member 16d. The right edge of the plate member 16c overlaps the left edge of the plate member 16e. The left edge of the plate-like member 16d is bent, for example, toward the canvas 11 side. The right edge of the plate-like member 16e is bent, for example, toward the canvas 11 side.

上記構成を有する移動手摺７であれば、図２で開示した構成の遮蔽体１３より厚い部材を板状部材１６ａ〜１６ｅとして使用しても、移動手摺７に必要な柔軟性を確保できる。なお、板状部材１６ａ〜１６ｅとして、ステンレス材或いは焼き入れ処理が施された鋼製の部材を採用することが好適である。   If it is the moving handrail 7 which has the said structure, even if it uses a member thicker than the shielding body 13 of the structure disclosed in FIG. 2 as plate-shaped members 16a-16e, the softness | flexibility required for the moving handrail 7 is securable. In addition, as the plate-like members 16a to 16e, it is preferable to adopt stainless steel members or steel members that have been subjected to quenching treatment.

実施の形態２．
図５は、この発明の実施の形態２における移動手摺７の断面図である。図５は、移動手摺７を図１のＡ方向から見た断面を示す。本実施の形態における移動手摺７は、例えば本体樹脂部１０、帆布１１、抗張体１２、導電体１７及び１８を備える。本体樹脂部１０、帆布１１及び抗張体１２の各構成は、実施の形態１で開示した各構成と同様である。 Embodiment 2. FIG.
FIG. 5 is a cross-sectional view of moving handrail 7 in the second embodiment of the present invention. FIG. 5 shows a cross section of the moving handrail 7 as seen from the direction A in FIG. The moving handrail 7 in the present embodiment includes, for example, a main body resin portion 10, a canvas 11, a tensile body 12, and conductors 17 and 18. Each structure of the main body resin part 10, the canvas 11 and the tensile body 12 is the same as each structure disclosed in the first embodiment.

導電体１７及び１８は、切れたワイヤが移動手摺７の把持面から飛び出す恐れがあることを保守作業等において検出することができるように備えられる。導電体１７及び１８は、電気を通し易い部材からなることが好ましい。導電体１７及び１８として、銅、アルミ等の金属からなる部材を採用することが好適である。導電体１７及び１８として、カーボン繊維等からなる部材を採用しても良い。導電体１７及び１８は、本体樹脂部１０の内部に設けられる。導電体１７及び１８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 conductors 17 and 18 are provided so that it can be detected in maintenance work or the like that there is a possibility that the broken wire may jump out of the gripping surface of the moving handrail 7. The conductors 17 and 18 are preferably made of a member that easily conducts electricity. As the conductors 17 and 18, it is preferable to employ a member made of a metal such as copper or aluminum. As the conductors 17 and 18, a member made of carbon fiber or the like may be employed. The conductors 17 and 18 are provided inside the main body resin portion 10. The conductors 17 and 18 are disposed over the entire length of the main body resin portion 10 along the length of the main body resin portion 10.

導電体１７は、帆布１１の反対側から抗張体１２を覆うように配置される。抗張体１２は、導電体１７と帆布１１との間に配置される。図５に示す横断面において、導電体１７の右側の縁部は一番右に配置された抗張体１２より更に右側に突出するように配置される。導電体１７の左側の縁部は一番左に配置された抗張体１２より更に左側に突出するように配置される。   The conductor 17 is disposed so as to cover the tensile body 12 from the opposite side of the canvas 11. The tensile body 12 is disposed between the conductor 17 and the canvas 11. In the cross section shown in FIG. 5, the right edge of the conductor 17 is disposed so as to protrude further to the right than the tensile body 12 disposed on the rightmost side. The left edge of the conductor 17 is disposed so as to protrude further to the left than the tensile body 12 disposed on the leftmost side.

導電体１８は、導電体１７と同様に、帆布１１の反対側から抗張体１２を覆うように配置される。導電体１８は、導電体１７より把持面側に配置される。即ち、導電体１７は、導電体１８と抗張体１２との間に配置される。図５に示す横断面において、導電体１８の右側の縁部は一番右に配置された抗張体１２より更に右側に突出するように配置される。導電体１８の左側の縁部は一番左に配置された抗張体１２より更に左側に突出するように配置される。また、導電体１７の右側の縁部は、導電体１８の右側の縁部より更に右側に突出するように配置される。導電体１８の左側の縁部は、導電体１７の左側の縁部より更に左側に突出するように配置される。   Similar to the conductor 17, the conductor 18 is disposed so as to cover the tensile body 12 from the opposite side of the canvas 11. The conductor 18 is disposed closer to the holding surface than the conductor 17. That is, the conductor 17 is disposed between the conductor 18 and the tensile body 12. In the cross section shown in FIG. 5, the right edge of the conductor 18 is arranged so as to protrude further to the right than the tensile body 12 arranged on the right. The left edge of the conductor 18 is disposed so as to protrude further to the left than the tensile body 12 disposed on the leftmost side. In addition, the right edge of the conductor 17 is disposed so as to protrude further to the right than the right edge of the conductor 18. The left edge of the conductor 18 is arranged to protrude further to the left than the left edge of the conductor 17.

上述したように、抗張体１２を構成するワイヤが切れると、切れたワイヤが本体樹脂部１０の内部で少しずつ移動する。上記構成を有する移動手摺７では、切れたワイヤが把持面に向かって移動すると、ワイヤの先端部が導電体１７に当たる。切れたワイヤは、時間をかけて導電体１７を貫通する。その後、切れたワイヤが把持面に向かって更に移動すると、ワイヤの先端部が導電体１８に当たる。切れたワイヤは、時間をかけて導電体１８を貫通する。   As described above, when the wire constituting the tensile body 12 is cut, the cut wire moves little by little inside the main body resin portion 10. In the moving handrail 7 having the above configuration, when the broken wire moves toward the gripping surface, the tip of the wire hits the conductor 17. The broken wire penetrates the conductor 17 over time. Thereafter, when the broken wire further moves toward the gripping surface, the tip of the wire hits the conductor 18. The broken wire penetrates the conductor 18 over time.

作業員は、エスカレータの保守作業を行う時に、導電体１７及び１８の通電状態を確認する。例えば、作業員は、マルチメータの測定用端子の一方を導電体１７に接触させ、他方を導電体１８に接触させる。測定用端子を差し込むための検査穴１９ａ及び１９ｂを本体樹脂部１０に予め形成しておいても良い。例えば、検査穴１９ａは、導電体１７の表面が露出するように、図２に示す横断面において一番右に配置された抗張体１２より更に右側に形成される。検査穴１９ｂは、導電体１８の表面が露出するように、一番左に配置された抗張体１２より更に左側に形成される。   The worker checks the energized state of the conductors 17 and 18 when performing maintenance work on the escalator. For example, the worker brings one of the measurement terminals of the multimeter into contact with the conductor 17 and brings the other into contact with the conductor 18. Inspection holes 19 a and 19 b for inserting measurement terminals may be formed in the main body resin portion 10 in advance. For example, the inspection hole 19a is formed on the right side of the tensile body 12 arranged on the rightmost side in the cross section shown in FIG. 2 so that the surface of the conductor 17 is exposed. The inspection hole 19b is formed further to the left than the tensile body 12 arranged on the leftmost side so that the surface of the conductor 18 is exposed.

ワイヤが導電体１７及び１８の双方を貫通すると、導電体１７及び１８がワイヤによって短絡される。マルチメータ等によって導電体１７及び１８の通電状態を確認することにより、作業員は、近いうちにワイヤが把持面から飛び出す可能性があることを判断できる。   As the wire passes through both conductors 17 and 18, the conductors 17 and 18 are shorted by the wire. By confirming the energization state of the conductors 17 and 18 with a multimeter or the like, the worker can determine that the wire may jump out of the gripping surface in the near future.

図６は、移動手摺７の要部を示す断面図である。誤検出を防止するため、導電体１７と導電体１８との間には絶縁体が設けられる。絶縁体は、本体樹脂部１０を構成する樹脂でも他の樹脂でも良い。即ち、導電体１７及び１８は、互いに接触することがないように本体樹脂部１０の内部に設けられる。   FIG. 6 is a cross-sectional view showing a main part of the moving handrail 7. In order to prevent erroneous detection, an insulator is provided between the conductor 17 and the conductor 18. The insulator may be a resin constituting the main body resin portion 10 or another resin. That is, the conductors 17 and 18 are provided inside the main body resin portion 10 so as not to contact each other.

上記構成を有する移動手摺７であれば、切れたワイヤが把持面から飛び出す前にワイヤが把持面から飛び出す恐れがあることを保守作業等において容易に検出できる。このため、切れたワイヤが移動手摺７の把持面から飛び出す前に移動手摺７の交換作業等を適切に行うことができる。   In the case of the moving handrail 7 having the above configuration, it is possible to easily detect in a maintenance operation or the like that the wire may jump out of the gripping surface before the cut wire jumps out of the gripping surface. For this reason, before the broken wire jumps out from the gripping surface of the moving handrail 7, the replacement work of the moving handrail 7 can be appropriately performed.

なお、切れたワイヤが導電体１８を貫通しなくても、ワイヤが導電体１８に接触すれば上記検出は可能である。切れたワイヤの先端部が把持面に達するのを遅らせるため、導電体１８として、導電体１７よりワイヤが貫通し難い部材を採用しても良い。例えば、導電体１８として、導電体１７より硬い部材或いは密度が高い部材を採用しても良い。   Even if the broken wire does not penetrate the conductor 18, the detection can be performed if the wire contacts the conductor 18. In order to delay the end of the cut wire from reaching the gripping surface, a member that is less likely to penetrate the wire than the conductor 17 may be employed as the conductor 18. For example, a member harder than the conductor 17 or a member having a higher density may be adopted as the conductor 18.

本実施の形態に示す移動手摺７においても、抗張体１２によって所望の引張強度が付与される。導電体１７及び１８が抗張体１２の機能を備える必要はない。このため、移動手摺７に必要な柔軟性が導電体１７及び１８によって損なわれることはない。   Also in the moving handrail 7 shown in the present embodiment, a desired tensile strength is imparted by the tensile body 12. The conductors 17 and 18 do not have to have the function of the tensile body 12. For this reason, the flexibility required for the moving handrail 7 is not impaired by the conductors 17 and 18.

図７は、移動手摺７の他の例を示す断面図である。図７に示す移動手摺７は、図５に示す構成に加え、遮蔽体１３を更に備える。遮蔽体１３の機能は、実施の形態１で開示した機能と同じである。   FIG. 7 is a cross-sectional view showing another example of the moving handrail 7. The moving handrail 7 shown in FIG. 7 further includes a shield 13 in addition to the configuration shown in FIG. The function of the shield 13 is the same as the function disclosed in the first embodiment.

図７に示す例では、遮蔽体１３は、本体樹脂部１０の内部に設けられる。遮蔽体１３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。遮蔽体１３は、帆布１１の反対側から抗張体１２を覆うように配置される。遮蔽体１３は、導電体１８より把持面側に配置される。即ち、導電体１８は、遮蔽体１３と導電体１７との間に配置される。図７に示す横断面において、遮蔽体１３の両側の縁部１３ａは、一番外側に配置された抗張体１２より更に側方に突出するように配置される。   In the example shown in FIG. 7, the shield 13 is provided inside the main body resin portion 10. The shield 13 is disposed along the length of the main body resin portion 10 over the entire length of the main body resin portion 10. The shield 13 is arranged so as to cover the tensile body 12 from the opposite side of the canvas 11. The shield 13 is disposed closer to the gripping surface than the conductor 18. That is, the conductor 18 is disposed between the shield 13 and the conductor 17. In the cross section shown in FIG. 7, the edges 13 a on both sides of the shield 13 are arranged so as to protrude further sideward than the tensile body 12 arranged on the outermost side.

図７は、移動手摺７の横断面において、遮蔽体１３が一枚の板状の部材からなる例を示す。図７に示すように、遮蔽体１３の縁部１３ａを帆布１１側に折り曲げても良い。また、遮蔽体１３は、図３に示す構成を有していても良い。   FIG. 7 shows an example in which the shield 13 is made of a single plate-like member in the cross section of the moving handrail 7. As shown in FIG. 7, the edge 13a of the shield 13 may be bent toward the canvas 11 side. Further, the shield 13 may have the configuration shown in FIG.

上記構成を有する移動手摺７であれば、切れたワイヤが移動手摺７の把持面から飛び出すことを遮蔽体１３によって防止できる。   If it is the moving handrail 7 which has the said structure, it can prevent with the shielding body 13 that the cut wire jumps out from the holding surface of the moving handrail 7. FIG.
