The plurality of steps 3 are arranged in a staircase pattern on a constant slope portion of the outward path of the passenger conveyor 1.
　制御盤４は、例えば乗客コンベア１の上端部に設けられる。制御盤４は、駆動装置２の動作を制御する装置である。駆動装置２の動作は、例えば駆動装置２の運転または停止である。制御盤４は、駆動装置２に接続される。 The control panel 4 is provided, for example, at the upper end of the passenger conveyor 1. The control panel 4 is a device that controls the operation of the drive device 2. The operation of the drive device 2 is, for example, operation or stop of the drive device 2. The control panel 4 is connected to the drive device 2.
　一対の欄干５の一方は、複数のステップ３の左側に設けられる。一対の欄干５の他方は、複数のステップ３の右側に設けられる。一対の欄干５の各々は、移動手摺６と、ガイドレール７と、安全装置８と、を備える。移動手摺６は、駆動装置２が発生させる駆動力によって、乗客コンベア１の上側を往路として循環移動する環状の部材である。移動手摺６は、例えばゴムおよびキャンバスによって形成される。ガイドレール７は、移動手摺６の循環移動をガイドする機器である。一対の欄干５の各々は、上階側および下階側の各々に収納部９を有する。収納部９は、往路を移動した移動手摺６を欄干５の内部に収納する部分である。収納部９は、帰路を移動した移動手摺６が欄干５の内部から出る部分でもある。安全装置８は、上階側の収納部９または下階側の収納部９の少なくとも一方に設けられる。 One of the pair of balustrades 5 is provided on the left side of the plurality of steps 3. The other of the pair of balustrades 5 is provided on the right side of the plurality of steps 3. Each of the pair of balustrades 5 includes a moving handrail 6, a guide rail 7, and a safety device 8. The moving handrail 6 is an annular member that circulates around the upper side of the passenger conveyor 1 as an outward path by a driving force generated by the driving device 2. The moving handrail 6 is formed of, for example, rubber and canvas. The guide rail 7 is a device that guides the circular movement of the moving handrail 6. Each of the pair of balustrades 5 has a storage portion 9 on each of the upper floor side and the lower floor side. The storage portion 9 is a portion for storing the moving handrail 6 that has moved on the outward route inside the balustrade 5. The storage portion 9 is also a portion where the moving handrail 6 that has moved on the return route comes out from the inside of the balustrade 5. The safety device 8 is provided in at least one of the storage portion 9 on the upper floor side and the storage portion 9 on the lower floor side.
　例えば乗客コンベア１の上り運転時に、駆動装置２は、制御盤４の制御によって駆動力を発生させる。複数のステップ３の各々は、駆動装置２が発生させた駆動力によって循環移動する。一対の欄干５の各々において、移動手摺６は、駆動装置２が発生させた駆動力によって循環移動する。移動手摺６は、下階側の収納部９から出た後に、ガイドレール７に沿って往路を移動する。移動手摺６は、往路を下階側から上階側に移動した後に、上階側の収納部９から欄干５の内部に収納される。移動手摺６は、欄干５の内部において帰路を上階側から下階側に移動する。 For example, during the uphill operation of the passenger conveyor 1, the drive device 2 generates a driving force under the control of the control panel 4. Each of the plurality of steps 3 circulates and moves by the driving force generated by the driving device 2. In each of the pair of balustrades 5, the moving handrail 6 circulates and moves by the driving force generated by the driving device 2. The moving handrail 6 moves on the outward route along the guide rail 7 after exiting from the storage portion 9 on the lower floor side.

　乗客コンベア１の上り運転時に、乗客は、一対の欄干５の移動手摺６の一方の外周をつかんで下階側から複数のステップ３のいずれかに乗る。乗客は、往路を移動するステップ３の上に立ち止まって上階側に移動する。 During the uphill operation of the passenger conveyor 1, the passenger grabs the outer circumference of one of the moving handrails 6 of the pair of balustrades 5 and gets on one of the plurality of steps 3 from the lower floor side. Passengers stop on step 3 of the outbound route and move upstairs.
　図２および図３は、実施の形態１に係る安全装置の構成図である。
　図２において、図１のＡ部における鉛直断面図が示される。図２は、欄干５の内部から見た断面図である。 2 and 3 are block diagrams of the safety device according to the first embodiment.
FIG. 2 shows a vertical cross-sectional view of part A in FIG. FIG. 2 is a cross-sectional view seen from the inside of the balustrade 5.
　図２に示されるように、移動手摺６の断面は、Ｃ字状の形状である。移動手摺６は、ガイドレール７を外周から覆っている。 As shown in FIG. 2, the cross section of the moving handrail 6 has a C-shape. The moving handrail 6 covers the guide rail 7 from the outer circumference.
　安全装置８は、移動手摺６において異物の挟まりを検知する装置である。安全装置８は、保護体１０と、支持部１１と、を備える。保護体１０は、移動手摺６を外周から覆う部分である。保護体１０は、例えば断面がＣ字状の筒状の部分を有する。保護体１０は、例えばゴム材料によって形成される。支持部１１は、欄干５の収納部９において保護体１０を支持する部分である。 The safety device 8 is a device that detects the pinching of foreign matter on the moving handrail 6. The safety device 8 includes a protective body 10 and a support portion 11. The protective body 10 is a portion that covers the moving handrail 6 from the outer circumference. The protective body 10 has, for example, a tubular portion having a C-shaped cross section. The protective body 10 is formed of, for example, a rubber material. The support portion 11 is a portion that supports the protective body 10 in the storage portion 9 of the balustrade 5.
　図３において、乗客コンベア１の左右方向から見た図１のＡ部の拡大図が示される。
　この例において、移動手摺６は、前方から後方に移動して欄干５の収納部９の内部に収納される。すなわち、収納部９において、前側は進行方向の上流側である。収納部９において、後側は進行方向の下流側である。 FIG. 3 shows an enlarged view of part A of FIG. 1 as viewed from the left-right direction of the passenger conveyor 1.
In this example, the moving handrail 6 moves from the front to the rear and is stored inside the storage portion 9 of the balustrade 5. That is, in the storage portion 9, the front side is the upstream side in the traveling direction. In the storage portion 9, the rear side is the downstream side in the traveling direction.
　保護体１０の軸方向は、移動手摺６の進行方向に向けられる。保護体１０において移動手摺６の進行方向の上流側の端部は、第１端部１２である。この例において、第１端部１２は、保護体１０の中央の筒状の部分より大きい外径を有するつば状の部分である。保護体１０において移動手摺６の進行方向の下流側の端部は、第２端部１３である。保護体１０は、第１端部１２から進行方向の側に延びる切込み１４を有する。保護体１０は、切込み１４によって第１端部１２の側から開くように分割されている。なお、切込み１４は、第２端部１３にまで達していてもよい。 The axial direction of the protective body 10 is directed to the traveling direction of the moving handrail 6. The end portion of the protective body 10 on the upstream side in the traveling direction of the moving handrail 6 is the first end portion 12. In this example, the first end portion 12 is a brim-shaped portion having an outer diameter larger than the central tubular portion of the protective body 10. The end portion of the protective body 10 on the downstream side in the traveling direction of the moving handrail 6 is the second end portion 13. The protecting body 10 has a notch 14 extending from the first end portion 12 toward the traveling direction. The protective body 10 is divided by a notch 14 so as to open from the side of the first end portion 12. The notch 14 may reach the second end portion 13.
　支持部１１は、固定板１５と、可動板１６と、ボルト１７と、ナット１８と、押さえバネ１９と、支持板２０と、を備える。 The support portion 11 includes a fixing plate 15, a movable plate 16, a bolt 17, a nut 18, a holding spring 19, and a support plate 20.
　固定板１５は、支持部１１の前側に設けられる。固定板１５は、例えば鉛直方向に延びる金属板である。固定板１５は、貫通孔２１を有する。 The fixing plate 15 is provided on the front side of the support portion 11. The fixing plate 15 is, for example, a metal plate extending in the vertical direction. The fixing plate 15 has a through hole 21.
　可動板１６は、下端を支点として前後方向に回転可能に設けられる。可動板１６は、固定板１５の後方に重なる位置に配置される。可動板１６は、中間部に貫通孔２２を有する。可動板１６の貫通孔２２は、可動板１６が固定板１５の後方に重ねられるときに固定板１５の貫通孔２１に重なる位置に設けられる。この例において、貫通孔２２は、鉛直方向に長い長孔である。 The movable plate 16 is provided so as to be rotatable in the front-rear direction with the lower end as a fulcrum. The movable plate 16 is arranged at a position overlapping behind the fixed plate 15. The movable plate 16 has a through hole 22 in the intermediate portion. The through hole 22 of the movable plate 16 is provided at a position where the movable plate 16 overlaps the through hole 21 of the fixed plate 15 when the movable plate 16 is overlapped behind the fixed plate 15. In this example, the through hole 22 is an elongated hole long in the vertical direction.
　ボルト１７は、固定板１５の前方から貫通孔２１および貫通孔２２の順に通される。ナット１８は、可動板１６の後方からボルト１７に留められる。 The bolt 17 is passed through the through hole 21 and the through hole 22 in this order from the front of the fixing plate 15. The nut 18 is fastened to the bolt 17 from the rear of the movable plate 16.
　押さえバネ１９は、移動手摺６の進行方向の反対側に押し付ける弾性力を保護体１０に加える部材である。この例において、押さえバネ１９は、コイルバネである。押さえバネ１９は、ボルト１７に通される。押さえバネ１９は、可動板１６の後面とナット１８との間に圧縮された状態で配置される。押さえバネ１９は、可動板１６が固定板１５の後方に重なるように可動板１６に力を加えている。 The pressing spring 19 is a member that applies an elastic force that presses the moving handrail 6 to the opposite side in the traveling direction to the protective body 10. In this example, the pressing spring 19 is a coil spring. The pressing spring 19 is passed through the bolt 17. The pressing spring 19 is arranged in a compressed state between the rear surface of the movable plate 16 and the nut 18. The pressing spring 19 applies a force to the movable plate 16 so that the movable plate 16 overlaps the fixed plate 15 behind.
　支持板２０は、可動板１６の上端に例えばネジ止めによって取り付けられる。支持板２０は、保護体１０を支持する板である。支持板２０は、例えば金属板である。この例において、支持板２０は、いす状の形状に折れ曲がっている。支持板２０は、可動板１６の上端に取り付けられた箇所から、後方に折れ曲がる。支持板２０は、可動板１６の上端に取り付けられた箇所より後方において、上方に立ち上がる。支持板２０の上方に立ち上がる箇所は、保護体１０の第２端部１３に取り付けられる。 The support plate 20 is attached to the upper end of the movable plate 16 by, for example, screwing. The support plate 20 is a plate that supports the protective body 10. The support plate 20 is, for example, a metal plate. In this example, the support plate 20 is bent into a chair shape. The support plate 20 bends rearward from a portion attached to the upper end of the movable plate 16. The support plate 20 rises upward behind the portion attached to the upper end of the movable plate 16. The portion that rises above the support plate 20 is attached to the second end portion 13 of the protective body 10.
　ここで、支持板２０は弾性力によって第１端部１２を開く力を保護体１０に加えてもよい。このとき、支持板２０は、開きバネの例である。支持板２０の上方に立ち上がる箇所は、例えば前面が反るような板バネとして形成される。このとき、板バネの弾性力によって、支持板２０は、第１端部１２を開く力を保護体１０に加える。 Here, the support plate 20 may apply a force to open the first end portion 12 to the protective body 10 by an elastic force. At this time, the support plate 20 is an example of an opening spring. The portion that rises above the support plate 20 is formed as, for example, a leaf spring that warps the front surface. At this time, due to the elastic force of the leaf spring, the support plate 20 applies a force to open the first end portion 12 to the protective body 10.
　安全装置８は、安全スイッチ２３と、意匠板２４と、を備える。 The safety device 8 includes a safety switch 23 and a design plate 24.
　安全スイッチ２３は、移動手摺６の進行方向の側への保護体１０の変位を検知する機器である。安全スイッチ２３は、検知器の例である。安全スイッチ２３は、支持部１１に固定して取り付けられる。安全スイッチ２３の先端は、可動板１６の後面に接触している。安全スイッチ２３は、保護体１０の変位を検知するときに検知信号を出力しうるように、制御盤４に接続される。 The safety switch 23 is a device that detects the displacement of the protective body 10 toward the traveling direction side of the moving handrail 6. The safety switch 23 is an example of a detector. The safety switch 23 is fixedly attached to the support portion 11. The tip of the safety switch 23 is in contact with the rear surface of the movable plate 16. The safety switch 23 is connected to the control panel 4 so that a detection signal can be output when the displacement of the protective body 10 is detected.
　意匠板２４は、欄干５において固定されている。意匠板２４は、前面に意匠面２５を有する。意匠面２５は、欄干５の外部に露出する部分である。意匠板２４は、裏面に複数の突起２６を有する。複数の突起２６は、第１端部１２の外周を進行方向の上流側から被さって押えている。裏面に突起２６を有する意匠板２４は、被せ部の例である。 The design plate 24 is fixed at the balustrade 5. The design plate 24 has a design surface 25 on the front surface. The design surface 25 is a portion exposed to the outside of the balustrade 5. The design plate 24 has a plurality of protrusions 26 on the back surface. The plurality of protrusions 26 cover and press the outer periphery of the first end portion 12 from the upstream side in the traveling direction. The design plate 24 having the protrusion 26 on the back surface is an example of the covering portion.
　乗客コンベア１の通常運転時において、保護体１０は、押さえバネ１９の弾性力によって可動板１６および支持板２０を介して移動手摺６の進行方向の反対側に押し付けられる。保護体１０の第１端部１２は、意匠板２４の裏面に押し付けられている。このとき、移動手摺６の進行方向の側に保護体１０は変位しない。安全スイッチ２３は、検知信号を出力しない。制御盤４は、安全スイッチ２３から検知信号が入力されないので、乗客コンベア１の通常運転を継続させる。 During normal operation of the passenger conveyor 1, the protective body 10 is pressed by the elastic force of the pressing spring 19 to the opposite side of the moving handrail 6 in the traveling direction via the movable plate 16 and the support plate 20. The first end portion 12 of the protective body 10 is pressed against the back surface of the design plate 24. At this time, the protective body 10 is not displaced toward the moving handrail 6 in the traveling direction. The safety switch 23 does not output a detection signal. Since the detection signal is not input from the safety switch 23 to the control panel 4, the normal operation of the passenger conveyor 1 is continued.
　意匠板２４は、裏面の突起２６によって保護体１０の第１端部１２に移動手摺６の進行方向の上流側から被さる。保護体１０の第１端部１２は、意匠板２４の突起２６によって外周から押えられる。このとき、保護体１０の第１端部１２は、開かない。 The design plate 24 covers the first end portion 12 of the protective body 10 from the upstream side in the traveling direction of the moving handrail 6 by the protrusion 26 on the back surface. The first end portion 12 of the protective body 10 is pressed from the outer circumference by the protrusion 26 of the design plate 24. At this time, the first end portion 12 of the protective body 10 does not open.
　続いて、図４を用いて、安全装置８の機能を説明する。
　図４は、実施の形態１に係る安全装置の構成図である。
　図４において、異物が挟まるときの安全装置８が示される。 Subsequently, the function of the safety device 8 will be described with reference to FIG.
FIG. 4 is a configuration diagram of the safety device according to the first embodiment.
FIG. 4 shows a safety device 8 when a foreign object is caught.
　乗客コンベア１が運転しているときに、異物が移動手摺６とともに収納部９に入り込む場合を考える。図示されない異物は、移動手摺６とともに進行方向に移動する。異物は、上流側から保護体１０に接触して挟まる。異物は、移動手摺６とともにさらに進行方向に移動する。挟まった異物は、上流側から保護体１０を進行方向に押し込む。保護体１０は、支持板２０とともに進行方向に押し込まれて変位する。可動板１６は、支持板２０とともに、押さえバネ１９の弾性力に抗しながら後方に回転する。可動板１６は、接触している安全スイッチ２３の先端を押し込む。安全スイッチ２３は、可動板１６に押し込まれることによって、保護体１０の変位を検知する。安全スイッチ２３は、検知信号を制御盤４に出力する。検知信号が入力されるときに、制御盤４は、駆動装置２に停止の制御信号を出力する。停止の制御信号が入力されるときに、駆動装置２は、停止する。 Consider a case where a foreign object enters the storage unit 9 together with the moving handrail 6 while the passenger conveyor 1 is operating. The foreign matter (not shown) moves in the traveling direction together with the moving handrail 6. The foreign matter comes into contact with the protective body 10 from the upstream side and is pinched. The foreign matter further moves in the traveling direction together with the moving handrail 6. The pinched foreign matter pushes the protective body 10 in the traveling direction from the upstream side. The protective body 10 is pushed in the traveling direction together with the support plate 20 and is displaced. The movable plate 16 rotates backward together with the support plate 20 while resisting the elastic force of the pressing spring 19. The movable plate 16 pushes the tip of the safety switch 23 in contact with the movable plate 16. The safety switch 23 detects the displacement of the protective body 10 by being pushed into the movable plate 16. The safety switch 23 outputs a detection signal to the control panel 4. When the detection signal is input, the control panel 4 outputs a stop control signal to the drive device 2. When the stop control signal is input, the drive device 2 stops.
　このとき、保護体１０は、後方に変位している。保護体１０の第１端部１２は、被せ部の例である意匠板２４の突起２６から外れている。このため、保護体１０の第１端部１２は、外周から押えられていない。これにより、保護体１０は、切込み１４によって第１端部１２が開くようになる。挟まった異物が取り除かれる場合に、保護体１０の第１端部１２が開かれる。また、開きバネの例である支持板２０が弾性力によって第１端部１２を開く力を保護体１０に加えている場合に、保護体１０が後方に変位するときに、第１端部１２は支持板２０の弾性力によって自然に開く。異物は、開いた第１端部１２の側から、進行方向の反対側に引き出されて取り除かれる。 At this time, the protective body 10 is displaced rearward. The first end portion 12 of the protective body 10 is detached from the protrusion 26 of the design plate 24, which is an example of the covering portion. Therefore, the first end portion 12 of the protective body 10 is not pressed from the outer circumference. As a result, the first end portion 12 of the protective body 10 is opened by the notch 14. When the pinched foreign matter is removed, the first end 12 of the protective body 10 is opened. Further, when the support plate 20 which is an example of the opening spring applies a force for opening the first end portion 12 to the protective body 10 by an elastic force, when the protective body 10 is displaced rearward, the first end portion 12 Opens naturally due to the elastic force of the support plate 20. The foreign matter is pulled out from the side of the open first end portion 12 to the opposite side in the traveling direction and removed.
　以上に説明したように、実施の形態１に係る安全装置８は、保護体１０と、検知器と、被せ部と、を備える。乗客コンベア１の移動手摺６は、循環移動する。保護体１０は、移動手摺６を外周から覆う。保護体１０は、切込み１４によって第１端部１２が開くように分割される。切込み１４は、第１端部１２から移動手摺６の進行方向の側に延びる。第１端部１２は、進行方向の上流側の端部である。検知器は、進行方向の側への保護体１０の変位を検知する。被せ部は、保護体１０の第１端部１２が開かないように第１端部１２の外周を進行方向の上流側から被さって押さえる。 As described above, the safety device 8 according to the first embodiment includes a protective body 10, a detector, and a covering portion. The moving handrail 6 of the passenger conveyor 1 circulates and moves. The protective body 10 covers the moving handrail 6 from the outer circumference. The protective body 10 is divided by the notch 14 so that the first end portion 12 is opened. The notch 14 extends from the first end portion 12 toward the moving handrail 6 in the traveling direction. The first end portion 12 is an end portion on the upstream side in the traveling direction. The detector detects the displacement of the protective body 10 toward the traveling direction. The covering portion covers and presses the outer circumference of the first end portion 12 from the upstream side in the traveling direction so that the first end portion 12 of the protective body 10 does not open.
　保護体１０の上流側の第１端部１２は、通常運転時において、被せ部によって押さえられることで閉じた状態を維持する。このため、保護体１０を一体化させるエネルギーが消費されない。異物が挟まるときに、保護体１０は、後方に押し込まれる。このとき、第１端部１２は、被せ部から外れる。これにより、保護体１０は、第１端部１２の側が開くようになる。このため、挟まった異物を取り除くことが容易になる。また、異物を第１端部１２の側から引き抜くときに、被せ部は、第１端部１２から外れている。このため、被せ部は、第１端部１２を閉じる方向に保護体１０を絞る力を加えない。これにより、挟まった異物を取り除くことが容易になる。安全装置８は、保護体１０を一体化させるために電磁石または真空ポンプなどの装置を必要としない。このため、簡易な構造によって安全装置８が実現される。 The first end portion 12 on the upstream side of the protective body 10 is held in a closed state by being pressed by the covering portion during normal operation. Therefore, the energy for integrating the protecting body 10 is not consumed. When a foreign object is caught, the protective body 10 is pushed backward. At this time, the first end portion 12 comes off from the covering portion. As a result, the protective body 10 opens on the side of the first end portion 12. Therefore, it becomes easy to remove the pinched foreign matter. Further, when the foreign matter is pulled out from the side of the first end portion 12, the covering portion is separated from the first end portion 12. Therefore, the covering portion does not apply a force to squeeze the protective body 10 in the direction of closing the first end portion 12. This makes it easy to remove the pinched foreign matter. The safety device 8 does not require a device such as an electromagnet or a vacuum pump to integrate the protective body 10. Therefore, the safety device 8 is realized by a simple structure.
　また、安全装置８は、押さえバネ１９を備える。押さえバネ１９は、弾性力によって保護体１０の第１端部１２を被せ部に押し付ける。 Further, the safety device 8 includes a holding spring 19. The pressing spring 19 presses the first end portion 12 of the protective body 10 against the covering portion by an elastic force.
　押さえバネ１９は、被せ部が第１端部１２から外れないように抵抗する力を保護体１０に加える。これにより、例えば通常運転時の振動などによって被せ部が外れることが抑制される。このため、安全装置８の誤作動などが抑制される。安全装置８は、より安定に動作するようになる。 The pressing spring 19 applies a force to the protective body 10 so that the covering portion does not come off from the first end portion 12. As a result, it is possible to prevent the covering portion from coming off due to vibration during normal operation, for example. Therefore, malfunction of the safety device 8 and the like are suppressed. The safety device 8 will operate more stably.
　また、安全装置８は、開きバネを備える。開きバネは、進行方向の下流側の保護体１０の第２端部１３に設けられる。開きバネは、弾性力によって第１端部１２を開く力を保護体１０に加える。 Further, the safety device 8 is provided with an opening spring. The opening spring is provided at the second end portion 13 of the protective body 10 on the downstream side in the traveling direction. The opening spring applies a force to open the first end portion 12 to the protective body 10 by an elastic force.
　被せ部が外れるときに、開きバネは、弾性力によって第１端部１２を開く。このため、第１端部１２は、大きく開きやすい。これにより、挟まった異物を取り除くことがより容易になる。 When the covering portion comes off, the opening spring opens the first end portion 12 by elastic force. Therefore, the first end portion 12 is easy to open wide. This makes it easier to remove the pinched foreign matter.
　なお、保護体１０は、第１端部１２が左右方向に開くように分割されてもよい。保護体１０は、第１端部１２が開くように３つ以上の部分に分割されてもよい。すなわち、保護体１０は、２つ以上の切込み１４を有してもよい。 The protective body 10 may be divided so that the first end portion 12 opens in the left-right direction. The protecting body 10 may be divided into three or more portions so that the first end portion 12 opens. That is, the protecting body 10 may have two or more notches 14.
　被せ部は、意匠板２４と別に設けられる例えばキャップ部であってもよい。被せ部は、欄干５において固定されている。被せ部は、第１端部１２の外周の全周を押えてもよい。被せ部は、第１端部１２の外周の一部を押えてもよい。 The covering portion may be, for example, a cap portion provided separately from the design plate 24. The covering portion is fixed in the balustrade 5. The covering portion may press the entire circumference of the outer circumference of the first end portion 12. The covering portion may press a part of the outer circumference of the first end portion 12.
　続いて、図５を用いて実施の形態１の変形例を説明する。
　図５は、実施の形態１の変形例に係る安全装置の構成図である。 Subsequently, a modified example of the first embodiment will be described with reference to FIG.
FIG. 5 is a configuration diagram of a safety device according to a modified example of the first embodiment.
　意匠板２４は、裏面に押さえ溝２７を有する。押さえ溝２７は、第１端部１２の外周を進行方向の上流側から被さって押えている。裏面に押さえ溝２７を有する意匠板２４は、被せ部の例である。 The design plate 24 has a holding groove 27 on the back surface. The pressing groove 27 covers and presses the outer periphery of the first end portion 12 from the upstream side in the traveling direction. The design plate 24 having the holding groove 27 on the back surface is an example of the covering portion.
　実施の形態２．

In the second embodiment, the differences from the examples disclosed in the first embodiment will be described in detail. As for the features not described in the second embodiment, any of the features of the examples disclosed in the first embodiment may be adopted.
　図６は、実施の形態２に係る安全装置の構成図である。 FIG. 6 is a configuration diagram of the safety device according to the second embodiment.
　安全装置８は、掛け部２８と、保持部２９と、を備える。 The safety device 8 includes a hanging portion 28 and a holding portion 29.
　この例において、掛け部２８は、支持板２０に設けられる。掛け部２８は、保護体１０とともに変位する部分である。掛け部２８は、例えば支持板２０の上端から上方に立ち上がり、支持板２０の上端より上方において後方に折れ曲がる。 In this example, the hanging portion 28 is provided on the support plate 20. The hanging portion 28 is a portion that is displaced together with the protective body 10. For example, the hanging portion 28 rises upward from the upper end of the support plate 20 and bends backward above the upper end of the support plate 20.
　保持部２９は、例えば板バネである。保持部２９の後端は、安全装置８において固定されて取り付けられる。保持部２９は、前端に爪部３０を有する。爪部３０は、下方に折れ曲がる部分である。異物が挟まっていない通常時の安全装置８において、保持部２９は、掛け部２８の後方に折れ曲がった部分の上に爪部３０が乗るように反った状態に変形して配置される。 The holding portion 29 is, for example, a leaf spring. The rear end of the holding portion 29 is fixed and attached in the safety device 8. The holding portion 29 has a claw portion 30 at the front end. The claw portion 30 is a portion that bends downward. In the normal safety device 8 in which no foreign matter is caught, the holding portion 29 is deformed and arranged in a warped state so that the claw portion 30 rests on the portion bent behind the hanging portion 28.
　続いて、図７を用いて、安全装置８の機能を説明する。
　図７は、実施の形態２に係る安全装置の構成図である。
　図７において、異物が挟まるときの安全装置８が示される。 Subsequently, the function of the safety device 8 will be described with reference to FIG. 7.
FIG. 7 is a configuration diagram of the safety device according to the second embodiment.
FIG. 7 shows a safety device 8 when a foreign object is caught.
　乗客コンベア１が運転しているときに、異物が移動手摺６とともに収納部９に入り込む場合を考える。挟まる異物は、保護体１０を進行方向に押し込む。保護体１０は、掛け部２８とともに進行方向に変位する。掛け部２８の上方に立ち上がる部分は、保持部２９の爪部３０より後方に変位する。このとき、保持部２９は、弾性力によって平坦な状態に復元される。このとき、保持部２９の爪部３０は、掛け部２８に引っかかる。これにより、保持部２９は、保護体１０を変位したまま保持する。保護体１０は、押さえバネ１９によって移動手摺６の進行方向の上流側に戻らない。このため、保護体１０の第１端部１２は、開いた状態が維持される。異物は、開いている第１端部１２の側から、進行方向の反対側に引き出されて取り除かれる。 Consider a case where a foreign object enters the storage unit 9 together with the moving handrail 6 while the passenger conveyor 1 is operating. The pinched foreign matter pushes the protective body 10 in the traveling direction. The protective body 10 is displaced in the traveling direction together with the hanging portion 28. The portion that rises above the hanging portion 28 is displaced rearward from the claw portion 30 of the holding portion 29. At this time, the holding portion 29 is restored to a flat state by the elastic force. At this time, the claw portion 30 of the holding portion 29 is caught by the hanging portion 28. As a result, the holding portion 29 holds the protective body 10 in a displaced state. The protective body 10 does not return to the upstream side in the traveling direction of the moving handrail 6 due to the pressing spring 19. Therefore, the first end portion 12 of the protective body 10 is maintained in an open state. The foreign matter is pulled out from the side of the open first end portion 12 to the opposite side in the traveling direction and removed.
　以上に説明したように、実施の形態２に係る安全装置８は、掛け部２８と、保持部２９と、を備える。掛け部２８は、保護体１０とともに変位する。保持部２９は、保護体１０とともに進行方向の側に変位した掛け部２８を引っ掛ける。保持部２９は、保護体１０を進行方向の側に変位したまま保持する。 As described above, the safety device 8 according to the second embodiment includes a hanging portion 28 and a holding portion 29. The hanging portion 28 is displaced together with the protective body 10. The holding portion 29 hooks the hanging portion 28 displaced toward the traveling direction together with the protective body 10. The holding portion 29 holds the protective body 10 while being displaced toward the traveling direction.
　挟まった異物が取り除かれるときに、保持部２９は、保護体１０が異物とともに上流側に引き戻されることを妨げる。これにより、挟まった異物を取り除くことが、より容易になる。 When the pinched foreign matter is removed, the holding portion 29 prevents the protective body 10 from being pulled back to the upstream side together with the foreign matter. This makes it easier to remove the pinched foreign matter.
