Description

本発明は、下階の床面と上階の床面とを連絡するように設置される乗客コンベアに関する。   The present invention relates to a passenger conveyor installed so as to connect a floor surface of a lower floor and a floor surface of an upper floor.

乗客コンベアは、下階の天井部（上階の床部）に開設された開口を貫通して、下階の床面と上階の床面とを連絡するように設置されるものであるので、建屋の天井部と移動手摺りを備えた乗客コンベアの欄干との間には、三角形状の交差部（以下、かかる形状の交差部を「三角交差部」という。）が形成される。また、２基の乗客コンベアを並設した場合には、一方の乗客コンベアの欄干と他方の乗客コンベアの枠体との間に、三角交差部が形成される。   Since the passenger conveyor is installed so as to pass through the opening established in the ceiling (upper floor) of the lower floor and to connect the lower floor and the upper floor. A triangular intersection (hereinafter referred to as “triangular intersection”) is formed between the ceiling of the building and the railing of the passenger conveyor provided with the moving handrail. When two passenger conveyors are arranged side by side, a triangular intersection is formed between the balustrade of one passenger conveyor and the frame of the other passenger conveyor.

これらの三角交差部において、下階から上階に向けて移動する乗客コンベアから、何らかの物体が欄干を乗り越えて乗客コンベアの外側に突き出されると、三角交差部に物体が挟み込まれて、物体と乗客コンベアのいずれか一方又は双方が損傷を受ける虞がある。   At these triangular intersections, if any object is projected from the passenger conveyor moving from the lower floor to the upper floor over the balustrade and protruding outside the passenger conveyor, the object is sandwiched between the triangular intersection and the object Either one or both of the passenger conveyors may be damaged.

このため、三角交差部には、物体の挟みこみを防止するための安全装置（以下、三角ガード板という。）として、固定保護板を取り付けることが法規により定められている。また、この標準では、乗客コンベアの移動方向において固定保護板の前方側に、可動式警告板を設けることが推奨されている。   For this reason, it is stipulated by law that a fixed protective plate is attached to the triangular intersection as a safety device (hereinafter referred to as a triangular guard plate) for preventing the object from being caught. Further, in this standard, it is recommended that a movable warning plate be provided on the front side of the fixed protective plate in the moving direction of the passenger conveyor.

そして、三角ガード板の安全を高めるものとして、特開２０１１−１９００４４号公報（特許文献１）に記載されるものを挙げることができる。この公報には、三角ガード板（固定保護板及び可動式警告板）を、所定の平面形状を有する板状部材と、この板状部材の前縁側に取り付けられた、板状部材の板厚よりも内径が大きい円筒状部材とから構成することが示されている。これらの板状部材１０１及び円筒状部材１０２は、例えばアクリル等のプラスチック材料をもって作製される。   And as what improves the safety | security of a triangular guard board, what is described in Unexamined-Japanese-Patent No. 2011-190044 (patent document 1) can be mentioned. In this publication, a triangular guard plate (fixed protective plate and movable warning plate) is obtained from a plate-like member having a predetermined planar shape and a plate thickness of the plate-like member attached to the front edge side of the plate-like member. It is also shown that it is composed of a cylindrical member having a large inner diameter. These plate-like member 101 and cylindrical member 102 are made of a plastic material such as acrylic, for example.

特開２０１１−１９００４４号公報（要約及び段落００２３）JP2011-190044 (abstract and paragraph 0023)

ところで、例えば衣服の一部やバッグ等が欄干からはみ出した状態で三角交差部へ移行すると、三角ガード板が設置されているとしても、三角ガード板（特に、可動式警告板）の下方に潜り込むようにして衣服の一部やバッグ等が挟み込まれることが考えられる。この挟み込まれた状態から抜け出すためには、衣服やバッグ等を欄干側へと引き戻す必要がある。しかし、三角ガード板の板状部材の下縁部に十分な面取り等がなされていない、或いは板状部材の厚さ寸法（特許文献１では６ｍｍ程度）が比較的薄い部材である場合には、衣服やバッグ等が摺接する際に引っ掛かり、引き戻すのに時間がかかる虞があった。   By the way, for example, when a part of clothes or a bag protrudes from the balustrade and moves to a triangular intersection, even if a triangular guard plate is installed, it enters under the triangular guard plate (especially a movable warning plate). Thus, it is conceivable that a part of clothes, a bag, or the like is sandwiched. In order to get out of this pinched state, it is necessary to pull clothes, bags, etc. back to the balustrade side. However, when the chamfering or the like is not sufficiently performed on the lower edge portion of the plate-like member of the triangular guard plate, or the thickness dimension of the plate-like member (about 6 mm in Patent Document 1) is a relatively thin member, There is a possibility that it takes time to pull back when clothes, bags, etc. are caught in sliding contact.

本発明の目的は、三角ガード板の下方に挟み込まれた物体をより容易に引き戻すことのできる乗客コンベアを提供することにある。   The objective of this invention is providing the passenger conveyor which can pull back the object pinched | interposed under the triangular guard board more easily.

前記目的を達成するために、本発明は、建屋の下階の床面と上階の床面との間に設けられた枠体と、前記枠体の内側に配置され、無端状に連結されて循環する踏段と、前記枠体に取り付けられ、前記踏段の進行方向に沿って両側に配置された欄干とを備え、天井部と前記欄干との間に形成される三角交差部、又は並設された２基の乗客コンベアのうち、一方の乗客コンベアの枠体と他方の乗客コンベアの欄干との間に形成される三角交差部に配置される三角ガード板を有する乗客コンベアにおいて、前記三角ガード板は、板面が前記枠体の長手方向に沿うように配置される板状部材を有し、前記板状部材は、下縁部に、前記下縁部に沿って設けられた曲面体を有し、前記曲面体は、前記板状部材の板厚方向における全幅寸法が前記板状部材の板厚寸法よりも大きく、且つ下方に向かって乗客コンベアの幅方向外側に向けて曲げられた曲面を有する。 To achieve the above object, the present invention provides a frame provided between a floor surface of a lower floor of a building and a floor surface of an upper floor, and is disposed inside the frame body and connected endlessly. A step that circulates and a balustrade attached to the frame and arranged on both sides along the direction of travel of the step, or a triangular intersection formed between the ceiling and the balustrade, or juxtaposed Of the two passenger conveyors, the triangular guard having a triangular guard plate disposed at a triangular intersection formed between the frame of one passenger conveyor and the balustrade of the other passenger conveyor. plate has a plate-like member plate surfaces are arranged along the longitudinal direction of the frame body, the plate-like member, the lower edge, a curved body provided along the lower edge a, the curved surface body, the full width dimension in the plate thickness direction of the plate-like member of the plate-like member Thickness much larger than the dimension, that and having a curved surface bent outward in the width direction of the passenger conveyor downward.

本発明によれば、三角ガード板の下方に挟み込まれた物体をより容易に引き戻すことができる。なお、前述した以外の課題、構成および効果は、以下の実施形態の説明により明らかにされる。   According to the present invention, the object sandwiched below the triangular guard plate can be pulled back more easily. Problems, configurations, and effects other than those described above will be clarified by the following description of embodiments.

FIG. 3 is a longitudinal sectional view showing a shape example of the triangular guard plate according to the first embodiment. FIG. 4 is a longitudinal sectional view showing a shape example of the triangular guard plate according to the first embodiment.

本実施例の可動式警告板１２，２２は、板状部材３１と、この板状部材３１の前縁部に取り付けられる円筒状部材３２と、板状部材３１の下縁部に取り付けられる円筒状部材３３とから構成されている。   The movable warning plates 12 and 22 of the present embodiment include a plate-like member 31, a cylindrical member 32 attached to the front edge portion of the plate-like member 31, and a cylindrical shape attached to the lower edge portion of the plate-like member 31. The member 33 is comprised.

板状部材３１は、板面が枠体１の長手方向に沿うように配置される。板状部材３１の下縁部は上り用の乗客コンベア１００Ａの欄干４の傾斜に沿って傾斜した形状である。従って、円筒状部材３３も、板状部材３１の下縁部の傾斜に沿って取り付けられている。板状部材３１及び円筒状部材３２，３３は、例えばアクリル等のプラスチック材料をもって作製される。   The plate-like member 31 is disposed such that the plate surface is along the longitudinal direction of the frame body 1. The lower edge portion of the plate-like member 31 has a shape inclined along the inclination of the balustrade 4 of the passenger conveyor 100A for ascending. Therefore, the cylindrical member 33 is also attached along the inclination of the lower edge portion of the plate-like member 31. The plate-like member 31 and the cylindrical members 32 and 33 are made of a plastic material such as acrylic, for example.

円筒状部材３３は、板状部材３１の下縁部に設けられる曲面体（曲面部）を構成している。ここでは、可動式警告板１２，２２の下縁部に円筒状部材３３を取り付けた例を示したが、固定保護板１１、２１の下縁部に円筒状部材を取り付けることも勿論できる。   The cylindrical member 33 constitutes a curved surface (curved surface) provided at the lower edge of the plate-shaped member 31. Here, an example in which the cylindrical member 33 is attached to the lower edge portion of the movable warning plates 12 and 22 is shown, but it is of course possible to attach the cylindrical member to the lower edge portion of the fixed protective plates 11 and 21.

図２では、可動式警告板２２の可動式警告板１２と異なる部位を、一点鎖線で示している。可動式警告板２２は、下り用の乗客コンベア１００Ｂの枠体１に吊り下げられるため、上縁部２２ｃが乗客コンベア１００Ｂの枠体１の傾斜に沿って傾斜した形状である。可動式警告板１２において吊り下げ金具が掛け止められる掛止部１２ａ，１２ｂは、可動式警告板２２では掛止部２２ａ，２２ｂの位置に設けられる。   In FIG. 2, portions of the movable warning plate 22 that are different from the movable warning plate 12 are indicated by alternate long and short dash lines. Since the movable warning plate 22 is suspended from the frame 1 of the descending passenger conveyor 100B, the upper edge portion 22c is inclined along the inclination of the frame 1 of the passenger conveyor 100B. In the movable warning plate 12, the latching portions 12a and 12b to which the hanging metal fittings are latched are provided in the movable warning plate 22 at the positions of the latching portions 22a and 22b.

円筒状部材３２と円筒状部材３３とは、曲り部３４により連結され、一体的に形成されている。曲り部３４は、円筒状部材３２と円筒状部材３３との間を、曲線で接続している。また、円筒状部材３２と円筒状部材３３とは、板状部材３１の板厚よりも大きい外径を有している。板状部材３１の前縁部に設けられる円筒状部材３２と板状部材３１の下縁部に設けられる円筒状部材３３とが一体的に形成された状態で連結されていることにより、継ぎ目のない滑らかな形状にすることができる。   The cylindrical member 32 and the cylindrical member 33 are connected by a bent portion 34 and are integrally formed. The bent portion 34 connects the cylindrical member 32 and the cylindrical member 33 with a curved line. The cylindrical member 32 and the cylindrical member 33 have an outer diameter larger than the plate thickness of the plate member 31. By connecting the cylindrical member 32 provided at the front edge of the plate-shaped member 31 and the cylindrical member 33 provided at the lower edge of the plate-shaped member 31 in an integrally formed state, There can be no smooth shape.

これにより、図３に示すように、円筒状部材３３及び円筒状部材３３は、乗客コンベア１００Ａ，１００Ｂの長手方向に垂直な断面（幅方向断面）において、円筒状部材３２及び円筒状部材３３の全幅寸法ｔ３３が、板状部材３１の板厚寸法ｔ３１よりも大きい。すなわち、円筒状部材３３及び円筒状部材３３は、板状部材３１の板厚方向における全幅寸法ｔ３３が、板状部材３１の板厚寸法よりも大きい。   Thereby, as shown in FIG. 3, the cylindrical member 33 and the cylindrical member 33 are arranged in a cross section (width direction cross section) perpendicular to the longitudinal direction of the passenger conveyors 100 </ b> A and 100 </ b> B. The total width dimension t33 is larger than the plate thickness dimension t31 of the plate-like member 31. That is, the cylindrical member 33 and the cylindrical member 33 have a total width t33 in the plate thickness direction of the plate member 31 larger than the plate thickness of the plate member 31.

図３に示すように、円筒状部材３２及び円筒状部材３３の各中心線を含む平面上に板状部材３１が位置するように、円筒状部材３２及び円筒状部材３３を板状部材３１に対して取り付けてもよい。この場合、板状部材３１を円筒状部材３２及び円筒状部材３３の内部に延長すると、円筒状部材３２及び円筒状部材３３の各中心線は板状部材３１に含まれることになる。   As shown in FIG. 3, the cylindrical member 32 and the cylindrical member 33 are placed on the plate-like member 31 so that the plate-like member 31 is positioned on a plane including the center lines of the cylindrical member 32 and the cylindrical member 33. You may attach to. In this case, when the plate member 31 is extended into the cylindrical member 32 and the cylindrical member 33, the center lines of the cylindrical member 32 and the cylindrical member 33 are included in the plate member 31.

或いは図４に示すように、円筒状部材３２及び円筒状部材３３の外周面に接する接平面を形成するように、板状部材３１を円筒状部材３２及び円筒状部材３３に対して取り付けてもよい。なお図４の場合も、円筒状部材３２及び円筒状部材３３の全幅寸法ｔ３３は、板状部材３１の板厚寸法ｔ３１よりも大きい。   Alternatively, as shown in FIG. 4, the plate member 31 may be attached to the cylindrical member 32 and the cylindrical member 33 so as to form a tangential plane that contacts the outer peripheral surfaces of the cylindrical member 32 and the cylindrical member 33. Good. In the case of FIG. 4 as well, the overall width t33 of the cylindrical member 32 and the cylindrical member 33 is larger than the plate thickness t31 of the plate-like member 31.

図５は、本発明の第２実施例に係る乗客コンベアの三角ガード板を示す図である。図６は、第２実施例に係る三角ガード板の形状例を示す縦断面図である。図７は、第２実施例に係る三角ガード板の形状例を示す縦断面図である。図８は、第２実施例に係る三角ガード板の形状例を示す縦断面図である。なお図５では、図２と同様に、可動式警告板２２の可動式警告板１２と異なる部位を、一点鎖線で示している。   FIG. 5 is a view showing a triangular guard plate of a passenger conveyor according to the second embodiment of the present invention. FIG. 6 is a longitudinal sectional view showing a shape example of the triangular guard plate according to the second embodiment. FIG. 7 is a longitudinal sectional view showing a shape example of the triangular guard plate according to the second embodiment. FIG. 8 is a longitudinal sectional view showing a shape example of the triangular guard plate according to the second embodiment. In FIG. 5, similarly to FIG. 2, a portion of the movable warning plate 22 that is different from the movable warning plate 12 is indicated by a one-dot chain line.

第２実施例の可動式警告板１２，２２は、板状部材４１と、この板状部材４１の前縁部に取り付けられる円筒状部材４２とから構成されている。板状部材４１の下縁部は湾曲するように曲げられ、半円形状部（円弧部）４３が成形されている。なお、本実施例では、半円形状部４３が、下縁部に設けられる曲面体（曲面部）を構成している。また、ここでは、可動式警告板１２、２２の下縁部に半円形状部４３を成形した例を示したが、固定保護板１１、２１の下縁部に半円形状部を成形することも勿論できる。   The movable warning plates 12 and 22 of the second embodiment are composed of a plate-like member 41 and a cylindrical member 42 attached to the front edge of the plate-like member 41. A lower edge portion of the plate-like member 41 is bent so as to be curved, and a semicircular portion (arc portion) 43 is formed. In the present embodiment, the semicircular portion 43 constitutes a curved surface (curved surface) provided at the lower edge. Moreover, although the example which shape | molded the semicircle-shaped part 43 in the lower edge part of the movable warning plates 12 and 22 was shown here, shape | mold a semicircle-shaped part in the lower edge part of the fixed protection plates 11 and 21. Of course you can.

半円形状部４３は、図６に示すように、幅方向断面における形状を略Ｊ字状の断面としてもよい。或いは図７に示すように、より大きなＲ部を有する略Ｊ字状の断面としてもよい。具体的には、図６では半円形状部４３の断面が半円よりも小さい円弧を成しており、図７では半円形状部４３の断面が半円の円弧を成している。或いは図８に示すように、略円形の断面としたりすることができる。   As shown in FIG. 6, the semicircular portion 43 may have a substantially J-shaped cross section in the cross section in the width direction. Or as shown in FIG. 7, it is good also as a substantially J-shaped cross section which has a larger R part. Specifically, in FIG. 6, the cross section of the semicircular portion 43 forms an arc smaller than the semicircle, and in FIG. 7, the cross section of the semicircular portion 43 forms a semicircle arc. Or as shown in FIG. 8, it can be set as a substantially circular cross section.

なお図８では、半円形状部４３の断面が完全な円形を描いておらず、円弧部の端部４３ａと端部４３ｂとの間に隙間が存在する。円弧部の端部４３ａと端部４３ｂとが接触するまで半円形状部４３を湾曲させ、完全な円形を描くようにしてもよい。この場合、第１実施例の形状とほとんど変わらない形状にすることができる。   In FIG. 8, the cross section of the semicircular portion 43 does not form a complete circle, and there is a gap between the end portion 43 a and the end portion 43 b of the arc portion. The semicircular portion 43 may be curved until the end portion 43a and the end portion 43b of the arc portion come into contact with each other so as to draw a complete circle. In this case, the shape can be made almost the same as that of the first embodiment.

図６の可動式警告板１２，２２では、半円形状部４３の端部４３ａが可動式警告板１２，２２の最下端に位置する形状である。これに対して図７及び図８の可動式警告板１２，２２では、半円形状部４３の端部４３ａが可動式警告板１２，２２の最下端から上方に向けて折り返した形状である。半円形状部４３の端部４３ａが可動式警告板１２，２２の最下端から上方に向けて折り返した形状にすることにより、可動式警告板１２，２２の下方に潜り込むようにして挟み込まれた衣服やバッグを引き戻すときの摺接抵抗が小さくなる。このため、衣服やバッグをより容易に引き戻すことができる。   In the movable warning plates 12 and 22 of FIG. 6, the end 43 a of the semicircular portion 43 is positioned at the lowermost end of the movable warning plates 12 and 22. On the other hand, in the movable warning plates 12 and 22 of FIGS. 7 and 8, the end 43 a of the semicircular portion 43 is folded upward from the lowest end of the movable warning plates 12 and 22. The end portion 43a of the semicircular portion 43 is sandwiched so as to sink under the movable warning plates 12 and 22 by making the shape folded back upward from the lowermost end of the movable warning plates 12 and 22. The sliding resistance when pulling back clothes and bags is reduced. For this reason, clothes and a bag can be pulled back more easily.

半円形状部４３の端部４３ａは、乗客コンベアの幅方向において板状部材４１の板面部４１ａよりも外側に位置するように、乗客コンベアの幅方向外側に向けて曲げられていることが望ましい。これにより、半円形状部４３の端部４３ａの端面が衣服やバッグ、或いは乗客と直接接触するのを防ぐことができる。或いは、半円形状部４３の端部４３ａが板状部材４１の板面部４１ａよりも内側に位置する場合であっても、半円形状部４３の端部４３ａを図８に示す位置まで、すなわち半円形状部４３の全幅寸法が最大となる位置まで端部４３ａを折り返すことにより、端部４３ａの端面が衣服やバッグ、或いは乗客と直接接触するのを防ぐことができる。   It is desirable that the end portion 43a of the semicircular portion 43 is bent toward the outer side in the width direction of the passenger conveyor so as to be positioned outside the plate surface portion 41a of the plate-like member 41 in the width direction of the passenger conveyor. . Thereby, it can prevent that the end surface of the edge part 43a of the semicircle-shaped part 43 contacts a clothes, a bag, or a passenger directly. Alternatively, even when the end portion 43a of the semicircular portion 43 is located inside the plate surface portion 41a of the plate-like member 41, the end portion 43a of the semicircular portion 43 is moved to the position shown in FIG. By folding the end portion 43a to the position where the full width dimension of the semicircular portion 43 is maximized, it is possible to prevent the end surface of the end portion 43a from coming into direct contact with clothes, bags, or passengers.

本実施例においても、図６〜８に示すように、幅方向断面において、半円形状部４３の全幅寸法（板状部材３１の板厚方向における全幅寸法）ｔ４３は、板状部材４１の板厚寸法ｔ４１よりも大きい。   Also in this embodiment, as shown in FIGS. 6 to 8, in the cross section in the width direction, the full width dimension of the semicircular portion 43 (full width dimension in the plate thickness direction of the plate member 31) t43 is the plate of the plate member 41. It is larger than the thickness dimension t41.

図９は、本発明との比較例における、乗客コンベアの三角ガード板を示す図である。   FIG. 9 is a view showing a triangular guard plate of a passenger conveyor in a comparative example with the present invention.

比較例の三角ガード板２００は、厚みが６ｍｍ以上の角がない板状部材２０１と、この板状部材２０１の前縁側に取り付けられた、板状部材２０１の板厚よりも内径が大きい円筒状部材２０２とから構成されている。板状部材２０１及び円筒状部材２０２は、例えばアクリル等のプラスチック材料をもって作製される。   The triangular guard plate 200 of the comparative example has a plate-like member 201 with a thickness of 6 mm or more and a cylindrical shape having an inner diameter larger than the plate thickness of the plate-like member 201 attached to the front edge side of the plate-like member 201. The member 202 is comprised. The plate-like member 201 and the cylindrical member 202 are made of a plastic material such as acrylic, for example.

本比較例では、板状部材２０１の前縁側には円筒状部材２０２が設けられているものの、板状部材２０１の下縁部には円筒状部材が設けられていない。このため、板状部材２０１の下縁部が三角ガード板２００の外縁を成している。   In this comparative example, the cylindrical member 202 is provided on the front edge side of the plate-like member 201, but the cylindrical member is not provided on the lower edge portion of the plate-like member 201. For this reason, the lower edge portion of the plate-like member 201 forms the outer edge of the triangular guard plate 200.

衣服やバッグが比較例の三角ガード板２００の下方に潜り込むようにして挟み込まれた場合、衣服やバッグを欄干側へと引き戻す際、衣服やバッグは三角ガード板２００の下縁部に摺接する。このため、衣服やバッグを引き戻すのに時間がかかる。   When clothes and bags are sandwiched so as to sink under the triangular guard plate 200 of the comparative example, when the clothes and bags are pulled back to the balustrade side, the clothes and bags are in sliding contact with the lower edge of the triangular guard plate 200. For this reason, it takes time to pull back clothes and bags.

また比較例の三角ガード板２００では、衣服やバッグの挟み込みを防ぐために、円筒状部材２０２の下端を下方に延長した延長部２０２ａを設けている。このため、人や物が触れて三角ガード板２００が乗客コンベアの幅方向に揺れた際に、円筒状部材２０２の下端部が周囲の構造物に接触し易くなる。円筒状部材２０２の下端部の構造物への接触を防ぐためには、周囲の構造物との間に十分な間隔を置いて、乗客コンベアを配置する必要がある。   In addition, the triangular guard plate 200 of the comparative example is provided with an extension portion 202a in which the lower end of the cylindrical member 202 is extended downward in order to prevent the clothing or bag from being caught. For this reason, when a person or an object touches and the triangular guard plate 200 swings in the width direction of the passenger conveyor, the lower end portion of the cylindrical member 202 easily comes into contact with surrounding structures. In order to prevent the lower end portion of the cylindrical member 202 from coming into contact with the structure, it is necessary to arrange the passenger conveyor with a sufficient space between the structure and the surrounding structure.

本発明の第１及び第２実施例によれば、三角ガード板５、６の下縁部に曲面体（曲面部）、すなわち、円筒状部材３３及び半円形状部４３を設けたことにより、三角ガード板５、６の下方に潜り込むようにして挟み込まれた衣服やバッグを欄干４側へと引き戻す際、衣服やバッグは下縁部の曲面体に摺接する。このため、衣服やバッグをより容易に引き戻すことができ、これによって、安全性の向上を図ることができる。   According to the first and second embodiments of the present invention, the curved body (curved surface portion), that is, the cylindrical member 33 and the semicircular portion 43 are provided at the lower edge portions of the triangular guard plates 5 and 6. When the clothes and bags sandwiched so as to sink under the triangular guard plates 5 and 6 are pulled back to the balustrade 4 side, the clothes and bags are in sliding contact with the curved body at the lower edge. For this reason, clothes and bags can be pulled back more easily, thereby improving safety.

また本発明に係る三角ガード板５、６では、円筒状部材３３及び半円形状部４３を設けたことにより、円筒状部材３２，４２の下端を下方に延長する必要がない。このため、三角ガード板５、６の上下方向の寸法を短くすることができる。従って、三角ガード板５、６が乗客コンベアの幅方向に揺れた際に周囲の構造物に接触し難くなり、乗客コンベアと周囲の構造物との間の隙間を広くする必要がない。   In the triangular guard plates 5 and 6 according to the present invention, since the cylindrical member 33 and the semicircular portion 43 are provided, it is not necessary to extend the lower ends of the cylindrical members 32 and 42 downward. For this reason, the dimension of the up-down direction of the triangular guard plates 5 and 6 can be shortened. Therefore, when the triangular guard plates 5 and 6 are swung in the width direction of the passenger conveyor, it becomes difficult to contact the surrounding structure, and it is not necessary to widen the gap between the passenger conveyor and the surrounding structure.

乗客コンベアと周囲の構造物との間の隙間を広くできる場合は、円筒状部材３２，４２の下端を下方に延長してもよい。   When the gap between the passenger conveyor and the surrounding structure can be widened, the lower ends of the cylindrical members 32 and 42 may be extended downward.
