Description

本発明は、エスカレータを保護するエスカレータ用保護シートに関する。 TECHNICAL FIELD The present invention relates to an escalator protective sheet for protecting an escalator.

エスカレータを据え付けた後に、エスカレータ周辺の工事を行う際や、エスカレータが設けられている空間の天井に取り付けられている照明装置や天井パネルなどを修理したり交換したりするいわゆるメンテナンス工事を行う際などには、工事対象となる天井などから、ねじや工事で発生したかけらなどの各種の異物がエスカレータ上に落下することがある。したがって、このような工事を行う際には、落下するねじなどの異物がエスカレータの踏面や内部などに入り込むなどして傷つくことがないように、エスカレータの踏面などに保護シート（養生シートとも呼ばれる）を前もって被せて保護するなどの設置作業を行っている。また、前記メンテナンス工事などが終わると、被せた保護シートなどを撤去している。 When performing construction around the escalator after the escalator is installed, or when performing so-called maintenance work such as repairing or replacing lighting equipment or ceiling panels attached to the ceiling of the space where the escalator is installed. In this case, various kinds of foreign matter such as screws and fragments generated during construction may fall onto the escalator from the ceiling to be constructed. Therefore, when carrying out such work, put a protective sheet (also called a protective sheet) on the tread surface of the escalator to prevent foreign objects such as falling screws from entering the tread surface or inside the escalator and damaging it. We are doing installation work such as covering and protecting it in advance. In addition, when the maintenance work is completed, the protective sheet and the like are removed.

詳しくは、例えば、ねじなどの異物が、エスカレータの踏面上に落ちたり、エスカレータの踏面と例えば欄干の側面部内側の下部に設けられているスカートガードとの間の隙間などに落ちたりすると、エスカレータの構成部品が傷ついたり、エスカレータが正常に動かなくなるトラブルを発生したりする恐れがある。このため、エスカレータに直接異物が落ちると、より良好な安全性を確保するために、異物が落ちた箇所近傍の機械のユニット部分を交換する場合もあり、この場合には多くの手間がかかるとともに、交換部品等の多大な費用も発生する。したがって、このような不具合を生じないように、保護シートなどを予め被せるなどの設置作業を行っている。 More specifically, for example, if a foreign object such as a screw falls on the tread of the escalator or falls into the gap between the tread of the escalator and, for example, a skirt guard provided at the bottom inside the side of the handrail, the escalator will component parts may be damaged, or the escalator may not operate properly. For this reason, if a foreign object falls directly onto an escalator, it may be necessary to replace the machine unit near the point where the foreign object fell in order to ensure better safety. , a large amount of cost for replacement parts, etc. is also generated. Therefore, in order to prevent such problems from occurring, installation work such as covering with a protective sheet or the like is performed in advance.

この保護シートなどの設置作業などについて具体的に説明する。エスカレータの階段部は、エスカレータの利用者が踏む踏面と、踏面の間の高さ部分に対応する蹴上げ面と、これらの踏面や蹴上げ面を駆動するための構成部品などから構成されている。また、エスカレータには欄干が左右に立設されており、各欄干の上端には利用者が手を載せる手摺が設けられているとともに、欄干の側面部内側の下部にはスカートガードなどが設けられている。そして、保護シートなどの設置工事を行う際には、少なくともエスカレータの踏面や蹴上げ面などを覆うように、面状に広げることができる保護シート（合成樹脂製シートで、ブルーシートとも称せられる）を被せている。 The installation work of the protective sheet and the like will be specifically described. The stairway portion of an escalator is composed of a tread surface that a user of the escalator steps on, a riser surface corresponding to the height between the treads, and components for driving these treads and riser surface. In addition, the escalator has balustrade on the left and right, and the upper end of each balustrade is equipped with a handrail for users to put their hands on. ing. When installing a protective sheet, etc., a protective sheet (synthetic resin sheet, also called a blue sheet) that can be spread out to cover at least the treads and risers of the escalator should be used. covered.

また、エスカレータが設けられている空間の天井などの工事を行う際には、エスカレータの踏面に単管パイプなどを立てて工事用の足場を組む必要がある。したがって、この際には、単管パイプなどを設置する箇所が不安定とならないように、保護シートを階段部などに被せた後に、踏面に置いた保護シートの上に、踏面の大きさに合ったベニヤ板などの板材を置いて、この板材上に単管パイプなどを立設させている。また、板材が滑らないように、保護シートと板材との間にゴムマットなどを敷く場合もある。ベニヤ板などの板材は、足場を組んだり取り外したりする際に、足場や工事で用いる単管パイプなどを落としたり、工具などを落としたりした際の衝撃で踏面を破損しないようにするため、エスカレータの踏面を広い範囲（殆どの場合には全段に）に渡って敷いている。 In addition, when constructing the ceiling of a space in which an escalator is installed, it is necessary to set up a scaffold for construction by erecting a single pipe or the like on the tread surface of the escalator. Therefore, in this case, after covering the stairs with a protective sheet so that the place where the single pipe etc. will be installed will not become unstable, put a protective sheet that matches the size of the tread on the protective sheet placed on the tread. A plate material such as a plywood board is placed, and a single pipe or the like is erected on this plate material. In some cases, a rubber mat or the like is laid between the protective sheet and the plate to prevent the plate from slipping. Plywood and other board materials are used for escalator treads to prevent the tread from being damaged by the impact of dropping scaffolding, single pipes used in construction, or dropping tools when assembling or removing scaffolding. The tread is laid over a wide range (in most cases, all steps).

ところで、エスカレータの踏面などを保護するものとして、例えば、特許文献１や特許文献２に、エスカレータの養生装置やエスカレータ踏段の養生装置が開示されている。なお、一般に、エスカレータの踏面の短辺の長さ（奥行方向寸法）は、エスカレータの蹴上げ面の短辺の長さ（高さ）よりも長い。したがって、特許文献１や特許文献２に開示された前記養生装置でも、これに合わせて、踏面覆い部の短辺の長さは、蹴上げ面覆い部の短辺の長さよりも長く構成されている。 By the way, as devices for protecting escalator treads and the like, Patent Document 1 and Patent Document 2, for example, disclose an escalator curing device and an escalator step curing device. In general, the length of the short side of the tread surface of the escalator (dimension in the depth direction) is longer than the length of the short side of the riser surface of the escalator (height). Therefore, even in the curing devices disclosed in Patent Document 1 and Patent Document 2, the length of the short side of the tread surface covering portion is longer than the length of the short side of the riser surface covering portion. .

しかし、上記のようにブルーシートとも称せられる面状の保護シートを踏面や蹴上げ面の形状に合わせて覆ったり、踏面の寸法に合わせた板材を敷いたりする各作業を行うには、多くの手間や時間がかかってしまい、特にエスカレータの踏面を広い範囲（殆どの場合には全段に）に渡って敷く場合には、大変多くの手間や時間がかかってしまう。また、これらの保護シートや板材などを撤去する際には、保護シートや板材の上に落ちた異物などが、エスカレータの踏面と欄干の側面部内側との間の隙間などに落ちたりすることがないように注意する必要があるため、この際にも多くの手間や時間がかかってしまう。また、板材が滑らないように保護シートと板材との間にゴムマットなどを敷いた場合でも、作業者が上り下りする際に、板材がずれることを完全に防ぐことができず、安全性が低下するおそれがあった。 However, it takes a lot of time and effort to cover the planar protective sheet, also known as a blue sheet, according to the shape of the tread surface and riser surface, and to lay a plate material that matches the dimensions of the tread surface. In particular, when laying the treads of the escalator over a wide range (in most cases, all the steps), it takes a lot of labor and time. In addition, when removing these protective sheets and boards, foreign objects that have fallen on the protective sheets and boards may fall into the gap between the escalator tread and the inside of the side of the balustrade. Since it is necessary to be careful not to do so, it takes a lot of time and effort in this case as well. In addition, even if a rubber mat or the like is placed between the protective sheet and the board to prevent the board from slipping, it is not possible to completely prevent the board from slipping when the worker climbs up or down, which reduces safety. there was a risk of

特許文献１に、踏面と蹴上げ面を覆う踏段用シートと欄干を覆う欄干用シートが提案されている。しかし、これらの踏段用シートや欄干用シートでは、踏段用シートの両端を踏段と欄干のスカートガードとの間に挿入しているので、欄干用シートで挿入部を覆っていてもシートを撤去する際に踏面または蹴上げ部とスカートガードとの間に異物などが転がり込む場合がある。また、欄干用シート下端部は踏段の形状に応じて成形されていない（欄干用シート下端部は踏段の形状に応じて成形されているとは記載されていない）ので、蹴上げ面および踏面奥端部近傍は欄干用シート下端部が接触していない状態になる恐れがあり、その隙間から異物などが転がり込む場合がある。 Patent Literature 1 proposes a step sheet for covering a tread surface and a riser surface and a balustrade sheet for covering a balustrade. However, since both ends of the step sheet and the balustrade sheet are inserted between the steps and the skirt guard of the balustrade, the balustrade sheet must be removed even if the insertion part is covered with the balustrade sheet. In some cases, foreign matter may roll between the tread or riser and the skirt guard. In addition, since the lower end of the balustrade sheet is not shaped according to the shape of the step (there is no description that the lower end of the balustrade sheet is shaped according to the shape of the step), There is a risk that the lower end of the balustrade sheet may not be in contact with the vicinity of the balustrade, and foreign matter may roll in through the gap.

特許文献２に、踏面を覆う板部材と、ライザー面を覆うシート部材とを備えたエスカレータ踏段の養生装置が提案されている。しかし、このエスカレータ踏段の養生装置では、側面覆い部がなく、踏面または蹴上げ面とスカートガードとの間に異物などが入り込む恐れがある。また、踏面覆い部同士が例えば同一方向に重なるようにエスカレータ用保護シートを折り畳んだ際に、踏面覆い部同士が前後方向や左右方向にずれない状態で折り畳むことができない。 Patent Literature 2 proposes an escalator step curing device that includes a plate member that covers the tread surface and a sheet member that covers the riser surface. However, in this escalator step curing device, there is no side covering portion, and there is a risk that foreign matter or the like may enter between the tread surface or riser surface and the skirt guard. Further, when the escalator protective sheet is folded so that the tread surface covering portions overlap in the same direction, the tread surface covering portions cannot be folded in a state in which they do not shift in the front-back direction or the left-right direction.

本発明は上記課題を解決するもので、エスカレータに多くの手間や時間をかけることなく設置したり、撤去したりすることができ、しかも、異物が、踏面や蹴上げ面だけでなく、これらの踏面や蹴上げ面と欄干の側面部内側との間の隙間に入り込むことを良好に防止できるエスカレータ用保護シートを提供することを目的とするものである。 DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems, and can be installed and removed from an escalator without taking a lot of time and effort. To provide a protective sheet for an escalator capable of satisfactorily preventing entry into a gap between a riser surface and the inner side of a balustrade.

上記課題を解決するために、本発明は、エスカレータを覆って保護するエスカレータ用保護シートであって、エスカレータの踏面を覆い、板材が配設されている踏面覆い部と、エスカレータの踏面の間の高さに対応する蹴上げ面を覆う蹴上げ面覆い部と、エスカレータの左右の欄干側面部内側を覆う側面覆い部と、を有し、踏面覆い部と蹴上げ面覆い部の長辺側が接合され、踏面覆い部と蹴上げ面覆い部の短辺側両辺に側面覆い部が接合され、これらの踏面覆い部と蹴上げ面覆い部と側面覆い部とが、踏面と蹴上げ面と欄干側面部内側の形状に応じて一体型に成形されており、踏面覆い部に、開口部を通して板材を収納する板材収納部と、開口部を開閉する着脱体と、が設けられていることを特徴とする。 In order to solve the above problems, the present invention provides an escalator protective sheet for covering and protecting an escalator, which covers a tread surface of the escalator, and is provided between a tread surface covering portion in which a plate material is arranged and the tread surface of the escalator. The escalator has a riser surface covering part covering the riser surface corresponding to the height and a side surface covering part covering the inside of the left and right balustrade side parts of the escalator, and the tread surface covering part and the long side of the riser surface covering part are joined to form the tread surface.

A side connected to the tread surface covering portion which is the immediately upper step is connected to a middle portion in the depth direction of the lower surface of the tread surface covering portion.

また、本発明のエスカレータ用保護シートは、蹴上げ面覆い部における設置時に蹴上げ面の縦方向に沿う長さと設置時に直上段の踏面覆い部に重なる前記途中部分までの長さとを合わせた蹴上げ面覆い部の長さが、踏面覆い部における前記途中部分から、この踏面覆い部の奥端辺までの長さと略同一であることを特徴とする。 In addition, the escalator protective sheet of the present invention is a riser surface cover in which the length along the vertical direction of the riser surface when installed in the riser surface cover portion and the length up to the middle portion overlapping the tread surface cover portion of the immediately upper step when installed are combined. The length of the portion is substantially the same as the length from the midway portion of the tread covering portion to the innermost edge of the tread covering portion.

また、本発明のエスカレータ用保護シートは、踏面覆い部に、開口部を通して板材を収納する板材収納部と、開口部を開閉する着脱体と、が設けられていることを特徴とする。 Further, the escalator protective sheet of the present invention is characterized in that the tread covering portion is provided with a plate storage portion for storing the plate through the opening and a detachable body for opening and closing the opening.

また、本発明のエスカレータ用保護シートは、側面覆い部の外側に、エスカレータの欄干側面部内側に付着する付着部が設けられていることを特徴とする。 Further, the escalator protective sheet of the present invention is characterized in that an attachment portion that attaches to the inside of the balustrade side portion of the escalator is provided on the outside of the side surface covering portion.

また、本発明のエスカレータ用保護シートは、側面覆い部に、当該エスカレータ用保護シートの折り畳み時に折り畳み位置を案内する折り畳み用案内部が設けられていることを特徴とする。 Further, the escalator protective sheet of the present invention is characterized in that the side cover section is provided with a folding guide section for guiding the folding position when the escalator protective sheet is folded.

また、本発明のエスカレータ用保護シートは、蹴上げ面覆い部と側面覆い部とが折り畳み自在に構成され、エスカレータの踏面の間の高さが小さくなっている箇所でも設置可能に構成されていることを特徴とする。 Further, in the escalator protective sheet of the present invention, the riser surface covering portion and the side surface covering portion are configured to be foldable so that the sheet can be installed even in a place where the height between the treads of the escalator is small. characterized by

本発明によれば、踏面覆い部と蹴上げ面覆い部とに加えて、エスカレータの左右の欄干側面部内側を覆う側面覆い部を有し、これらの踏面覆い部と蹴上げ面覆い部と側面覆い部とが踏面と蹴上げ面と欄干側面部内側の形状に応じて一体型に成形されていることにより、エスカレータ用保護シートをエスカレータ上で広げるだけで、素早くかつ簡単に、すなわち、少ない時間で手間を省きながら、エスカレータに設置することができ、撤去作業も素早くかつ簡単に行うことができる。例えば、このエスカレータが、列車が出入りする駅などに設置されている場合には、工事（例えばメンテナンス作業など）を実施可能な時間が、終電から始発までの限られた時間（例えば、４時間程度）内に行わなければならないが、これによれば、エスカレータ用保護シートを広げたり撤去したりする作業を大幅に短縮することができるため、メンテナンス作業などの時間を長く確保することができる利点がある。また、エスカレータ内側の左右の欄干側面部内側を覆う側面覆い部を有し、踏面覆い部と蹴上げ面覆い部の短辺側両辺に側面覆い部を接合させることにより、ねじなどの異物が、踏面や蹴上げ面だけでなく、これらの踏面や蹴上げ面と欄干側面部内側との間の隙間に、落ちたり入り込んだりすることを良好に防止することができ、良好な信頼性を得ることができる。また、これらの踏面覆い部と蹴上げ面覆い部と側面覆い部とが、踏面と蹴上げ面と欄干側面部内側の形状に応じて一体型に成形されてエスカレータを覆っているので、保護した踏面上を作業者が歩くことができ、そのスペースも多く取れる。また、踏面覆い部に板材が配設されて一体化されているので、作業者が上り下りしても、板材がずれることを防止でき、安全性を向上させることができる。さらに、踏面覆い部に、開口部を通して板材を収納する板材収納部と、開口部を開閉する着脱体と、が設けられているので、踏面覆い部の板材収納部に収納する板材を容易に交換することができる。したがって、このエスカレータ用保護シートを設置した後に行う工事やエスカレータ用保護シートの持ち運び作業などに合わせて、剛性の大きな板材や軽量で持ち運びしやすい板材などを収納することができる。また、大きさや厚みなどが異なる板材に変更することも容易に行える。 According to the present invention, in addition to the tread surface covering portion and the riser surface covering portion, the side surface covering portion is provided to cover the inside of the left and right balustrade side portions of the escalator, and these tread surface covering portion, the riser surface covering portion and the side surface covering portion are provided. are integrally formed according to the shape of the tread surface, riser surface, and the inner side of the balustrade, the escalator protective sheet can be quickly and easily spread over the escalator, that is, in a short amount of time and effort. It can be installed on the escalator while omitting it, and the removal work can be done quickly and easily. For example, if this escalator is installed at a station where trains come and go, the time during which construction (for example, maintenance work) can be performed is limited to the time from the last train to the first train (for example, about 4 hours). ), the work of spreading and removing the protective sheet for the escalator can be greatly shortened, so there is the advantage of being able to secure a longer time for maintenance work, etc. be. In addition, the escalator has a side covering portion that covers the inside of the left and right balustrade side portions inside the escalator. It is possible to satisfactorily prevent falling or entering not only the tread surface and the riser surface but also the gap between the tread surface or the riser surface and the inside of the balustrade side part, and obtain good reliability. In addition, since the tread surface covering portion, the riser surface covering portion, and the side surface covering portion are integrally molded according to the shape of the tread surface, the riser surface, and the inner side of the balustrade, the escalator is covered with a protected tread surface. can be walked by workers, and a lot of space can be taken. In addition, since the plate member is arranged and integrated with the tread covering portion, the plate member can be prevented from slipping even when the operator climbs and descends, and safety can be improved. Further, since the tread covering portion is provided with the plate storage portion for storing the plate through the opening and the detachable body for opening and closing the opening, the plate stored in the plate storage portion of the tread cover can be easily replaced. can do. Therefore, it is possible to store a highly rigid board material or a light and easy-to-carry board material in accordance with the work to be done after installing the escalator protective sheet or the carrying work of the escalator protective sheet. Also, it is easy to change to a plate material having a different size, thickness, or the like.

また、蹴上げ面覆い部における、設置時に直上段となる踏面覆い部と接続される辺を、この踏面覆い部の下面における奥行方向の途中部分に接続することで、踏面覆い部同士が例えば上下方向に重なるようにエスカレータ用保護シートを折り畳んだ際に、踏面覆い部同士が前後方向や左右方向にずれる寸法が少ない状態で折り畳むことが可能となる。さらに、蹴上げ面覆い部における設置時に蹴上げ面の縦方向に沿う長さと設置時に直上段の踏面覆い部に重なる前記途中部分までの長さとを合わせた蹴上げ面覆い部の長さが、踏面覆い部における前記途中部分から、この踏面覆い部の奥端辺までの長さと略同一であるよう構成することにより、踏面覆い部同士が例えば上下方向に重なるようにエスカレータ用保護シートを折り畳んだ際に、踏面覆い部同士が前後方向や左右方向にずれない状態で折り畳むことができるので、エスカレータ用保護シートを極めてコンパクトな状態で折り畳むことができて、持ち運びが容易となるとともに保管スペースを小さくすることができる。 In addition, by connecting the side of the riser surface covering portion that is connected to the tread surface covering portion, which is the immediately upper step when installed, to the middle portion of the bottom surface of the tread surface covering portion in the depth direction, the tread surface covering portions can move vertically, for example. When the escalator protective sheet is folded so as to overlap with the escalator, it is possible to fold the tread surface cover parts in a state in which there is little displacement in the front-rear direction and the left-right direction. Furthermore, the length of the riser surface covering portion, which is the sum of the length along the vertical direction of the riser surface when installed in the riser surface covering portion and the length to the middle portion overlapping the tread surface covering portion of the immediately upper step when installed, is equal to the tread surface covering portion. By configuring the escalator protective sheet so that the length from the middle portion to the innermost edge of the tread cover portion is substantially the same as that of the tread cover portion, when the escalator protective sheet is folded so that the tread cover portions overlap each other in the vertical direction, for example, Since the tread cover parts can be folded in a state that they do not shift in the longitudinal direction and the lateral direction, the protective sheet for the escalator can be folded in an extremely compact state, making it easy to carry and reducing the storage space. can.

Therefore, the board material 11 with high rigidity or the light and easy-to-carry board material 11 can be stored in accordance with the work to be performed after installing the escalator protective sheet 10 or the carrying work of the escalator protective sheet 10.例文帳に追加In addition, it is possible to easily change to a plate material 11 having a different size, thickness, or the like.

エスカレータ用保護シート１０は、エスカレータ１の長さに合わせて、複数（複数組）のエスカレータ用保護シート１０同士を前後方向に合わせて設置することができるよう構成されている。この実施の形態のエスカレータ用保護シート１０においては、図１に示すように、最上段の蹴上げ面覆い部１３には、これより、前方（上方）に配置されたエスカレータ用保護シート１０の最下段の踏面覆い部１２の下に敷くことができるように、延長用踏面覆い部１５が設けられており、これにより、上下段側のエスカレータ用保護シート１０の接続箇所でも隙間なくエスカレータ１を覆うことができるようになっている。 The escalator protective sheet 10 is configured so that a plurality (a plurality of sets) of escalator protective sheets 10 can be installed in alignment with each other in the front-rear direction according to the length of the escalator 1 . In the escalator protective sheet 10 of this embodiment, as shown in FIG. 1, the riser surface covering portion 13 of the uppermost step has the lowermost step of the escalator protective sheet 10 arranged forward (above) therefrom. An extension tread cover part 15 is provided so that it can be laid under the tread cover part 12 of the escalator 1, so that the escalator 1 can be covered without gaps even at the connecting parts of the escalator protection sheets 10 on the upper and lower tier sides. is now possible.

また、図１などに示すように、エスカレータ用保護シート１０の側面覆い部１４の外側端部には、エスカレータ１の欄干側面部内側５に付着する付着部１６が設けられている。この実施の形態では、付着部１６は例えば滑り止め材で構成され、側面覆い部１４の外側端部に張り付けられている。また、この実施の形態では、付着部１６が、エスカレータ１の欄干側面部内側５の一部をなすインナーデッキ５Ｂに貼り付けられ、付着部１６を介して、エスカレータ用保護シート１０の側面覆い部１４をエスカレータ１の欄干側面部内側５に張り付けることができるよう構成されている。しかし、これに限るものではなく、付着部１６は、インナーデッキ５Ｂが無いエスカレータ１の欄干側面部内側５にも付着されるよう構成されている。なお、付着部１６は、滑り止め材以外のもの、例えば粘着面を有する材料でもよく、エスカレータ１の欄干側面部内側５に張り付けることが可能な材料であればよい。また、最上段の延長用踏面覆い部１５の下面に滑り止め材や粘着面を有する材料など張り付けるなどしてもよい。 Further, as shown in FIG. 1 and the like, an attachment portion 16 that attaches to the inner side 5 of the balustrade side portion of the escalator 1 is provided at the outer end portion of the side cover portion 14 of the escalator protective sheet 10 . In this embodiment, the attachment portion 16 is made of, for example, a non-slip material and adhered to the outer edge of the side cover portion 14 . In this embodiment, the attachment portion 16 is attached to the inner deck 5B forming a part of the inner side 5 of the balustrade side portion of the escalator 1, and the side cover portion of the escalator protective sheet 10 is attached via the attachment portion 16. 14 can be attached to the inner side 5 of the balustrade side portion of the escalator 1. - 特許庁However, it is not limited to this, and the attachment portion 16 is configured to be attached to the inner side 5 of the balustrade side portion of the escalator 1 without the inner deck 5B. Note that the attachment portion 16 may be made of a material other than the non-slip material, such as a material having an adhesive surface, as long as it can be attached to the inner side 5 of the balustrade side portion of the escalator 1 . Alternatively, a non-slip material or a material having an adhesive surface may be pasted on the lower surface of the uppermost extension tread cover portion 15 .

この構成によれば、側面覆い部１４の外側に、エスカレータ１の欄干側面部内側５に付着する付着部１６が設けられているので、このエスカレータ用保護シート１０を設置する際に、側面覆い部１４の付着部１６をエスカレータ１の欄干側面部内側５に付着させて容易に取り付けることができる。これにより、作業能率が向上するとともに、異物が、エスカレータ１の欄干側面部内側５と側面覆い部１４との間の隙間から内部に侵入することを確実に防止することができて、信頼性が向上する。 According to this configuration, since the attachment portion 16 attached to the inside 5 of the balustrade side portion of the escalator 1 is provided on the outside of the side surface covering portion 14, when the escalator protection sheet 10 is installed, the side surface covering portion The attaching part 16 of 14 is attached to the inner side 5 of the balustrade side part of the escalator 1 and can be easily attached. As a result, work efficiency is improved, and foreign matter can be reliably prevented from entering through the gap between the balustrade side portion inner side 5 and the side cover portion 14 of the escalator 1, thereby improving reliability. improves.

ここで、図７、図８などに示すように、エスカレータ用保護シート１０は、折り畳み自在に構成されている。また、図７、図８および図４などに示すとともに上記したように、蹴上げ面覆い部１３は、蹴上げ面４の上端部から直上段の踏面覆い部１２の下面に沿って奥端部に少し入り込むように、踏面覆い部１２と接続されている。つまり、蹴上げ面覆い部１３における、設置時に直上段の踏面覆い部１２と接続される辺が、この直上段の踏面覆い部１２の下面における奥行方向の途中部分に接続されている。 Here, as shown in FIGS. 7 and 8, the escalator protective sheet 10 is configured to be freely foldable. As shown in FIGS. 7, 8 and 4 and described above, the riser surface covering portion 13 extends from the upper end of the riser surface 4 along the lower surface of the tread surface covering portion 12 immediately above to the rear end portion. It is connected to the tread surface covering part 12 so as to penetrate. That is, the side of the riser surface covering portion 13 that is connected to the immediately upper tread surface covering portion 12 at the time of installation is connected to the middle portion in the depth direction of the lower surface of the immediately upper tread surface covering portion 12 .

なお、この蹴上げ面覆い部１３における直上段の踏面覆い部１２と接続される箇所を上段接続部１３ｄと称し、蹴上げ面覆い部１３における直下段の踏面覆い部１２と接続される箇所を下段接続部１３ｃと称する。また、設置時において蹴上げ面覆い部１３における直上段の踏面覆い部１２と重なる箇所を、上段重なり部１３ｂと称する。また、図４、図５などでは、蹴上げ面覆い部１３の上段重なり部１３ｂが分かり易いように、踏面覆い部１２とわずかな隙間をあけた状態で示しているが、実際には、蹴上げ面覆い部１３の上段重なり部１３ｂと踏面覆い部１２とは接触した状態で配設される。なお、この実施の形態では、蹴上げ面覆い部１３と、この蹴上げ面覆い部１３における直下段の踏面覆い部１２とは、踏面覆い部１２の奥端上部箇所（下段接続部１３ｃ）で接続されている。 A portion of the riser surface covering portion 13 connected to the tread surface covering portion 12 immediately above is referred to as an upper connection portion 13d, and a portion of the riser surface covering portion 13 connected to the tread surface covering portion 12 immediately below is referred to as a lower connection. This is referred to as section 13c. A portion of the riser surface covering portion 13 that overlaps the tread surface covering portion 12 immediately above when installed is referred to as an upper overlapping portion 13b. 4 and 5 show the upper overlapping portion 13b of the riser surface covering portion 13 with a slight gap from the tread surface covering portion 12 so as to make it easier to understand. The upper overlapping portion 13b of the covering portion 13 and the tread surface covering portion 12 are arranged in contact with each other. In this embodiment, the riser surface covering portion 13 and the tread surface covering portion 12 immediately below the riser surface covering portion 13 are connected at the rear end upper portion of the tread surface covering portion 12 (lower connecting portion 13c). ing.

また特に、図１、図４に示すように、蹴上げ面覆い部１３における設置時に蹴上げ面４の縦方向に沿う部分（立設面部１３ａと称す）の長さＬ１と、設置時に直上段の踏面覆い部１２に重なる前記途中部分（上段接続部１３ｄ）までの長さＬ２（すなわち、上段重なり部１３ｂの長さＬ２）と、を合わせた蹴上げ面覆い部１３の長さ（この例では、蹴上げ面覆い部１３の長さ）Ｌ１＋Ｌ２が、踏面覆い部１２における前記途中部分（上段接続部１３ｄ）から、この踏面覆い部１２の奥端辺１２ｇまでの部分（非蹴上げ面覆い部１７と称す）の長さＬ３と略同一とされている。なお、図４、図５などにおける１３ｆは、蹴上げ面覆い部１３における立設面部１３ａと上段重なり部１３ｂとの境界点を示し、エスカレータ１の階段部２における蹴上げ面４の上端部と踏面３の段鼻との接続箇所に対応する箇所を覆っている。 In particular, as shown in FIGS. 1 and 4, the length L1 of the portion of the riser surface covering portion 13 along the vertical direction of the riser surface 4 when installed (referred to as the standing surface portion 13a) The length L2 (that is, the length L2 of the upper overlapping portion 13b) up to the intermediate portion (upper connecting portion 13d) overlapping the cover portion 12 and the length of the riser surface covering portion 13 (in this example, the length of the riser The length of the surface covering portion 13) L1+L2 is the portion from the midway portion (upper connecting portion 13d) of the tread surface covering portion 12 to the rear edge 12g of the tread surface covering portion 12 (referred to as the non-riser surface covering portion 17). is substantially the same as the length L3 of . 4 and 5, etc., 13f indicates a boundary point between the standing surface portion 13a and the upper overlapping portion 13b in the riser surface covering portion 13, and the upper end portion of the riser surface 4 in the staircase portion 2 of the escalator 1 It covers the part corresponding to the connection part with the nosing.

そして、この構成により、エスカレータ用保護シート１０を、その踏面覆い部１２と蹴上げ面覆い部１３とが交互に上下に重なるように折り畳むと、図７、図８に示すように、踏面覆い部１２同士が前後方向（設置時における奥行方向）にずれない、コンパクトな状態で折り畳むことができるようになっている。 With this configuration, when the escalator protective sheet 10 is folded so that the tread surface covering portion 12 and the riser surface covering portion 13 are alternately overlapped vertically, the tread surface covering portion 12 is formed as shown in FIGS. It can be folded in a compact state without being displaced in the front-rear direction (the depth direction when installed).

つまり、一般的に、踏面覆い部１２の前後方向の長さは、蹴上げ面４に沿う蹴上げ面覆い部１３の略上下方向に沿う長さよりも長いので、例えば、蹴上げ面覆い部１３の上端辺が直上段の踏面覆い部１２の段鼻に接続されており、蹴上げ面覆い部１３’が単に蹴上げ面４の縦方向に沿う部分（立設面部１３ａと称す）の長さＬ１である場合には、比較例を示す図９に簡略的に示すように、１段毎に踏面覆い部１２と蹴上げ面覆い部１３との長さの差（Ｌ２＋Ｌ３－Ｌ１）の寸法分だけ、前後方向にずれた状態で畳まれてしまう。これに対して、本発明の実施の形態のエスカレータ用保護シート１０では、このようなことなく、踏面覆い部１２同士が前後方向（設置時における奥行方向）にずれない、コンパクトな状態で折り畳むことができるようになっている。 That is, in general, the length of the tread surface covering portion 12 in the front-rear direction is longer than the length of the riser surface covering portion 13 along the riser surface 4 along the substantially vertical direction. is connected to the step nosing of the tread surface covering portion 12 of the immediately upper stage, and the riser surface covering portion 13' is simply the length L1 of the portion along the vertical direction of the riser surface 4 (referred to as the standing surface portion 13a) 9 showing a comparative example, the difference in length between the tread surface covering portion 12 and the riser surface covering portion 13 (L2+L3-L1) is shifted in the front-rear direction for each step. It will be folded in a state. In contrast, the escalator protective sheet 10 according to the embodiment of the present invention does not have such a problem, and can be folded in a compact state so that the tread surface covering portions 12 do not shift in the front-rear direction (the depth direction when installed). is now possible.

すなわち、上記構成によれば、蹴上げ面覆い部１３における、設置時に直上段となる踏面覆い部１２と接続される辺が、この踏面覆い部１３の下面における奥行方向の途中部分である上段接続部１３ｄに接続され、蹴上げ面覆い部１３における設置時に蹴上げ面４の縦方向に沿う長さＬ１と設置時に直上段の踏面覆い部１２に重なる前記途中部分までの長さＬ２とを合わせた蹴上げ面覆い部１３の長さ（Ｌ１＋Ｌ２）が、踏面覆い部１２における上段接続部１３ｄから、この踏面覆い部１２の奥端辺までの長さＬ３と略同一である。これにより、図８に示すように、踏面覆い部１２同士が例えば上下方向に重なるようにエスカレータ用保護シート１０を折り畳んだ際に、踏面覆い部１２同士が前後方向や左右方向にずれない状態でエスカレータ用保護シート１０を折り畳むことができる。したがって、エスカレータ用保護シート１０を極めてコンパクトな状態で折り畳むことができて、持ち運びが容易となるとともに保管スペースを小さくすることができる。 That is, according to the above configuration, the side of the riser surface covering portion 13 that is connected to the tread surface covering portion 12, which is the immediately upper stage when installed, is the upper connection portion that is the middle portion of the bottom surface of the tread surface covering portion 13 in the depth direction. 13d, and the length L1 along the vertical direction of the riser surface 4 when installed in the riser surface covering portion 13 and the length L2 up to the middle portion overlapping the tread surface covering portion 12 immediately above when installed are combined. The length (L1+L2) of the cover portion 13 is substantially the same as the length L3 from the upper connection portion 13d of the tread cover portion 12 to the innermost edge of the tread cover portion 12 . As a result, as shown in FIG. 8, when the escalator protective sheet 10 is folded so that the tread surface covering portions 12 overlap each other in the vertical direction, the tread surface covering portions 12 are prevented from being displaced in the front-rear direction and the left-right direction. The escalator protective sheet 10 can be folded. Therefore, the escalator protective sheet 10 can be folded into a very compact state, which facilitates carrying and reduces the storage space.

また、エスカレータ用保護シート１０は、上記のように踏面覆い部１２や蹴上げ面覆い部１３を折り畳む際に、側面覆い部１４も折り畳めるよう構成されている。すなわち、図１０～図１４などに示すように、例えば、谷折り線１８と山折り線１９とに沿って折り畳むことで、側面覆い部１４も上下に折り畳めるよう構成されている。例えば、谷折り線１８は、エスカレータ用保護シート１０の側面覆い部１４における、踏面覆い部１２の奥端部と蹴上げ面覆い部１３の下端部との接続部分の両端部から延びるように形成され、これらの谷折り線１８の中間位置に山折り線１９が設けられる。これらの谷折り線１８や山折り線１９は予め折り目をつけるよう構成されていると好適であり、分かり易いように側面覆い部１４自体の色と異なる色で示されていてもよい。これらの谷折り線１８や山折り線１９は、当該エスカレータ用保護シート１０の折り畳み時に折り畳み位置を案内する折り畳み用案内部の一例である。 Further, the escalator protective sheet 10 is configured such that when the tread surface covering portion 12 and the riser surface covering portion 13 are folded as described above, the side surface covering portion 14 can also be folded. That is, as shown in FIGS. 10 to 14, for example, by folding along the valley fold line 18 and the mountain fold line 19, the side cover portion 14 can also be folded up and down. For example, the valley fold lines 18 are formed to extend from both ends of the connecting portion between the innermost end of the tread surface covering portion 12 and the lower end portion of the riser surface covering portion 13 in the side surface covering portion 14 of the escalator protective sheet 10 . , and a mountain fold line 19 is provided at an intermediate position between these valley fold lines 18 . These valley fold lines 18 and mountain fold lines 19 are preferably configured to be creases in advance, and may be shown in a color different from the color of the side cover portion 14 itself for easy understanding. These valley fold lines 18 and mountain fold lines 19 are examples of folding guides that guide the folding position when the escalator protective sheet 10 is folded.

また、折り畳み用案内部の他の例として、図１１、図１３に示すように、側面覆い部１４の内面における踏面覆い部１２の近傍箇所には、踏面覆い部１２を底面とし、山折り線１９の下端部を頂点とする略三角形状の折り畳みガイドプレート２０が貼り付けられている。この折り畳みガイドプレート２０を用いることで、山折り線１９で畳んだ部分を良好に重ねることができるように図られている。また、図１３、図１４に示すように、畳んだ部分が重なり合う部分につまむ際に目印となる目印部（マーク、折り畳み用案内部の他の例）２１を記載したり（切り欠いたり）してもよい。 Further, as another example of the folding guide portion, as shown in FIGS. 11 and 13 , on the inner surface of the side surface covering portion 14 , in the vicinity of the tread surface covering portion 12 , the tread surface covering portion 12 is used as the bottom surface, and a mountain fold line is provided. A substantially triangular folding guide plate 20 having the lower end of 19 as the vertex is attached. By using this folding guide plate 20, the parts folded along the mountain fold lines 19 can be satisfactorily overlapped. Also, as shown in FIGS. 13 and 14, a mark portion (mark, another example of a guide portion for folding) 21 that serves as a mark when the folded portion overlaps is indicated (notched). may

さらに、このエスカレータ用保護シート１０では、図１５、図１６に示すように、踏面覆い部１２や蹴上げ面覆い部１３および側面覆い部１４を折り畳んだ後に、これらが全て内部に折り畳まれた状態を良好に保持できるように、最上段の延長用踏面覆い部１５の上面（表面、図１５においては簡略的に示す）と、最下段の踏面覆い部１２の下面（裏面）とに互いに着脱できる、面状ファスナーなどの補助着脱体２２、２３を設けている。 Further, in the escalator protective sheet 10, as shown in FIGS. 15 and 16, after the tread surface covering portion 12, the riser surface covering portion 13 and the side surface covering portion 14 are folded, all of them are folded inside. The upper surface of the uppermost extension tread cover 15 (shown schematically in FIG. 15) and the lower surface (rear surface) of the lowermost tread cover 12 can be detached from each other so that they can be held well. Auxiliary attachment/detachment bodies 22 and 23 such as planar fasteners are provided.

なお、エスカレータ用保護シート１０の基材（踏面覆い部１２の板材１１以外の部分や、蹴上げ面覆い部１３、側面覆い部１４）としては、ポリエステル織物の両面に軟質塩化ビニル樹脂が含浸された折り畳み可能なシート（例えば、厚み０．４８ｍｍ、質量５６０ｇ／ｍ^２）を用いると好適であるが、これに限るものではない。すなわち、エスカレータ用保護シート１０の基材としては、当該エスカレータ用保護シート１０を繰り返し使用できるように、耐久性を有するシート材であればなんでもよい。エスカレータ用保護シート１０の基材は、いわゆるブルーシートを用いてもよく、基材の厚手の生地としてゴムシートを用いてもよい。また、雨漏りする場所においても、当該エスカレータ用保護シート１０を用いることができるように、前記基材として防水性を有する材料を用いてもよい。 As the base material of the escalator protective sheet 10 (parts of the tread surface covering portion 12 other than the plate material 11, the riser surface covering portion 13, and the side surface covering portion 14), both sides of the polyester fabric are impregnated with a soft vinyl chloride resin. A foldable sheet (for example, thickness 0.48 mm, mass 560 g/m ² ) is preferably used, but is not limited to this. That is, the base material of the escalator protective sheet 10 may be any sheet material that has durability so that the escalator protective sheet 10 can be used repeatedly. A so-called blue sheet may be used as the base material of the escalator protective sheet 10, and a rubber sheet may be used as the thick base material. Also, a waterproof material may be used as the base material so that the escalator protective sheet 10 can be used even in a place where rain leaks.

また、複数の蹴上げ面覆い部１３および複数の非蹴上げ面覆い部１７を一枚の前記基材で構成し、この基材に踏面覆い部１２や側面覆い部１４をミシン縫製または高周波ウェルダー溶着で隙間の内容に接合すると好適であるが、これに限るものではない。また、前記基材の表面の色を、ビスや埃などの異物が落下した際に、この異物を目視し易い色にするとさらに好適であるが、これに限るものではない。 Also, the plurality of riser surface covering portions 13 and the plurality of non-riser surface covering portions 17 are formed from one sheet of base material, and the tread surface covering portion 12 and the side surface covering portion 14 are sewn to this base material by machine sewing or high frequency welder welding. Although it is preferred to join to the contents of the gap, it is not limited to this. Further, it is more preferable to make the color of the surface of the base material such that when foreign matter such as screws or dust falls, it is easy to see the foreign matter, but it is not limited to this.

また、板材１１としては、例えばプラスチック製敷板を用いればよいが、これに限るものではなく、鉄柱などの足場を良好に支持することができる剛性などを有することが望ましい。また、板材１１は、持ち運びに便利なように、軽量であることが望ましいが、これに限るものでなく、樹脂製、木製、軽量な金属製の板など各種の板材を用いるとよい。 As the plate member 11, for example, a floor plate made of plastic may be used, but it is not limited to this, and it is desirable that the plate member 11 has a rigidity capable of supporting a scaffolding such as an iron pole. The plate 11 is preferably light in weight for easy portability, but is not limited to this, and various plate materials such as resin, wood, and lightweight metal plates may be used.

また、蹴上げ面覆い部１３と側面覆い部１４とが折り畳み自在に構成されているので、エスカレータ１の出入り口部分の踏面の間の高さ（蹴上げ面の高さ）が低くなる部分（小さい箇所）においてもこのエスカレータ保護シート１０を良好に設置することができる。また、図２、図１０に示すように、最上段の蹴上げ面覆い部１３と側面覆い部１２との接合方法は、面ファスナー２４、２５などの着脱手段を張り付けて、着脱可能としてもよい。すなわち、蹴上げ面覆い部１３と側面覆い部１２との接合部分には、面ファスナー２４、２５などの着脱手段を張り付けて、分離可能とする。そして、エスカレータ１の踏面の間の高さが低くなる部分に設置する場合、最上段部の蹴上げ面覆い部１３と側面覆い部１２の面ファスナー２４、２５の接合を剥し、最上段の延長用踏面覆い部１５と側面覆い部１４が踏面３と欄干側面部内側５から浮き上がって段差などができることを防止でき、段差などにより足が引っ掛かるなどの不具合が発生することを防止している。 In addition, since the riser surface covering portion 13 and the side surface covering portion 14 are configured to be foldable, the height between the treads (height of the riser surface) at the entrance portion of the escalator 1 is lowered (small portion). This escalator protection sheet 10 can also be installed satisfactorily. As shown in FIGS. 2 and 10, the uppermost riser surface covering portion 13 and the side surface covering portion 12 may be joined together by attaching detachable means such as hook-and-loop fasteners 24 and 25 to make them detachable. That is, attachment/detachment means such as hook-and-loop fasteners 24 and 25 are attached to the joint portion between the riser surface covering portion 13 and the side surface covering portion 12 so that they can be separated. When installing in a portion where the height between the treads of the escalator 1 is low, the joint between the riser surface covering portion 13 of the uppermost step and the hook-and-loop fasteners 24 and 25 of the side surface covering portion 12 is removed, and the extension of the uppermost step is removed. The tread cover part 15 and the side surface cover part 14 can be prevented from rising from the tread surface 3 and the inside 5 of the balustrade side part to form a step, etc., and the occurrence of trouble such as a foot being caught by the step can be prevented.

なお、上記の実施の形態においては、図４および図１７に示すように、蹴上げ面覆い部１３と、この蹴上げ面覆い部１３における直下段の踏面覆い部１２とは、踏面覆い部１２の後端上部箇所（下段接続部１３ｃ）で接続されている場合を述べたが、これに限るものではなく、図１８に示すように、踏面覆い部１２の後端下部箇所（下段接続部１３ｃ）で接続したり、図１９に示すように、踏面覆い部１２の後端下部近傍（少し前方）の、踏面覆い部１２の下面の途中箇所で接続したりしてもよい。 In the above embodiment, as shown in FIGS. 4 and 17, the riser surface covering portion 13 and the tread surface covering portion 12 directly below the riser surface covering portion 13 are positioned behind the tread surface covering portion 12. Although the case where it is connected at the upper end portion (lower connecting portion 13c) has been described, it is not limited to this, and as shown in FIG. Alternatively, as shown in FIG. 19, it may be connected at a midpoint on the lower surface of the tread covering portion 12 in the vicinity of the lower rear end portion (slightly forward) of the tread covering portion 12 .

また、上記実施の形態では側面覆い部１４により、エスカレータ１の欄干側面部内側５の下部に設けられているインナーデッキ５Ｂやスカートガード５Ｃを覆う場合を述べたが、これに限るものではなく、側面覆い部１４（および踏面覆い部１２、蹴上げ面覆い部１３）により、踏面３や蹴上げ面４との間の隙間を覆った状態で、エスカレータ１の欄干側面部内側５における少なくとも下部を覆うように構成すればよい。 Further, in the above-described embodiment, the side covering portion 14 covers the inner deck 5B and the skirt guard 5C provided at the lower portion of the balustrade side portion inner side 5 of the escalator 1, but the present invention is not limited to this. The side surface covering portion 14 (and the tread surface covering portion 12 and the riser surface covering portion 13) cover at least the lower portion of the balustrade side portion inner side 5 of the escalator 1 while covering the gap between the tread surface 3 and the riser surface 4. should be configured to

また、上記の実施の形態では、エスカレータ１が左右に２人が並ぶことができるいわゆる２人用のエスカレータ１である場合を図示したが、これに限るものではなく、いわゆる１人用のエスカレータに対しても同様の構成をエスカレータ用保護シート１０として適用可能である。 In the above embodiment, the escalator 1 is a so-called two-person escalator 1 that allows two people to stand side by side. The same configuration can be applied as the protective sheet 10 for escalator.
