When the lifting car 3 stops, after the car 3 stops in a stopping position, a driving part 11 projects and inserts an insertion part 13 into the storage member 8, and thereby, the piston member 7 extends and engages with the storage member 8, and a door of the elevator 1 opens thereafter. When the car 3 lifts from the stopping position, after the door is closed, the piston member 7 extracts the insertion part 13 from the storage member 8, and engagement between the piston member 7 and the storage member 8 is released.

Description

この発明は、エレベータの安全装置に関する。   The present invention relates to an elevator safety device.

従来のエレベータには、かごが停止位置に停止しているときに、かごが昇降しないようにする安全装置が設けられている。しかし、この安全装置に不具合が生じると、ドアが開いているときにかごが昇降してしまい、エレベータに乗ろうとしている人や物が昇降路の壁とかごとの間に挟まれて負傷または破損してしまうおそれがある。実際に、安全装置に不具合が生じて、東京都内の高校生が犠牲になるといった痛ましい事故が平成１８年６月に起こっている。この事故を受けて、国土交通省は、エレベータの安全装置を２系統設けることを義務化している。   A conventional elevator is provided with a safety device that prevents the car from going up and down when the car is stopped at the stop position. However, if this safety device fails, the car will move up and down when the door is open, and people or objects trying to get on the elevator will be pinched between the hoistway wall and the car and injured or damaged. There is a risk of it. In fact, a painful accident occurred in June 2006, in which a safety device malfunctioned and a high school student in Tokyo was sacrificed. In response to this accident, the Ministry of Land, Infrastructure, Transport and Tourism has obliged to install two systems of elevator safety devices.

２系統の安全装置はそれぞれ、別系統にすることが好ましい。例えば、かごを昇降させる昇降手段に対して設けられたものと、かご自体を停止位置に対して固定するものとの２系統が考えられる。後者の安全装置として、例えば、特許文献１に記載されたものが挙げられる。この安全装置は、エレベータのドアの開閉と共に動く金属くさび体がかごに設けられ、ドアが開くと、金属くさび体が、ガイドレールに設けられた筒状の鋼板掛止枠体内に挿入されて、かごが停止位置から上昇も下降もしないようになるものである。   Each of the two systems of safety devices is preferably a separate system. For example, there are two systems, one provided for lifting means for raising and lowering the car and the other for fixing the car itself to a stop position. Examples of the latter safety device include those described in Patent Document 1. This safety device is provided with a metal wedge body that moves with the opening and closing of the elevator door, and when the door opens, the metal wedge body is inserted into the cylindrical steel plate retaining frame body provided on the guide rail, The car does not rise or fall from the stop position.

特開２００８−４４７８２号公報JP 2008-44782 A

しかしながら、特許文献１の安全装置では、かごが停止位置に停止した後、ドアが開いてからでないとかごの固定が完了されない。かごが停止位置に停止してからドアが開くまでには、少なくとも若干のタイムラグが存在するのが一般的であり、この僅かの時間にかごが昇降してしまうと、金属くさび体が鋼板掛止枠体内に挿入されなくなってしまい、かごを停止位置から上昇も下降もしないようにすることができなくなってしまうという問題点があった。   However, in the safety device of Patent Document 1, after the car stops at the stop position, the car cannot be fixed until the door is opened. There is generally at least a slight time lag from when the car stops at the stop position until the door opens, and if the car moves up and down during this short period of time, the metal wedge will be hooked to the steel plate. There is a problem in that the car cannot be inserted into the frame and the car cannot be raised or lowered from the stop position.

この発明はこのような問題点を解決するためになされたもので、人や物がかごに乗り降りする間、確実にかごを停止位置から上昇も下降もしないようにすることができるエレベータの安全装置を提供することを目的とする。   The present invention has been made to solve such problems, and is an elevator safety device that can reliably prevent a car from rising and falling from a stop position while a person or an object gets on or off the car. The purpose is to provide.

この発明に係るエレベータの安全装置は、エレベータのかごに設けられた第１係合部と、前記かご以外の個所に固定されると共に前記第１係合部と係合可能な第２係合部とを備え、昇降中の前記かごが停止する場合には、停止位置に前記かごが停止したら、前記第１係合部と前記第２係合部とが係合し、その後に前記エレベータのドアが開き、前記かごが前記停止位置から昇降する場合には、前記ドアが閉じた後、前記第１係合部と前記第２係合部との係合が解除される。
前記第１係合部及び前記第２係合部のうちの一方が、突出可能な挿入部を有するピストン部材であり、他方が、前記挿入部が挿入可能な収容部材であり、前記挿入部が前記収容部材内に挿入することで、前記第１係合部と前記第２係合部とが係合し、前記挿入部が前記収容部材内に挿入されたときに、前記挿入部と前記収容部材との間の少なくとも一部に隙間が存在するのが好ましい。
前記かごを昇降する昇降手段が設けられ、該昇降手段には、前記かごが前記停止位置に停止中に前記昇降手段が前記かごを昇降させないようにする昇降手段安全装置が設けられていてもよい。
前記昇降手段は油圧で駆動され、前記ピストン部材は、機械式または流体式であってもよい。 An elevator safety device according to the present invention includes a first engagement portion provided in an elevator car, and a second engagement portion that is fixed to a place other than the car and is engageable with the first engagement portion. When the car that is moving up and down stops, when the car stops at the stop position, the first engagement portion and the second engagement portion are engaged, and then the door of the elevator When the door is opened and the car is raised and lowered from the stop position, the engagement between the first engagement portion and the second engagement portion is released after the door is closed.
One of the first engaging part and the second engaging part is a piston member having a projecting insertion part, the other is a housing member into which the insertion part can be inserted, and the insertion part is When the insertion portion is inserted into the housing member, the first engagement portion and the second engagement portion are engaged with each other, and the insertion portion and the housing are inserted when the insertion portion is inserted into the housing member. It is preferable that a gap exists between at least a part of the members.
Elevating means for elevating the car is provided, and the elevating means may be provided with elevating means safety device that prevents the elevating means from elevating the car while the car is stopped at the stop position. .
The elevating means may be driven hydraulically, and the piston member may be mechanical or fluidic.

この発明によれば、昇降中のかごが停止する場合には、停止位置にかごが停止したら、第１係合部と第２係合部とが係合され、その後にエレベータのドアが開くことにより、かごが停止してからドアが開くまでの間にかごが昇降してしまうことを防止でき、かごが停止位置から昇降する場合には、ドアが閉じた後に第１係合部と第２係合部との係合が解除されることにより、人や物のかごへの乗り降りが完全に終わった後にかごの停止位置に対する固定が解消されるので、人や物がかごに乗り降りする間、確実にかごを停止位置から上昇も下降もしないようにすることができる。   According to this invention, when the car that is being lifted / lowered stops, when the car stops at the stop position, the first engagement portion and the second engagement portion are engaged, and then the elevator door is opened. Thus, the car can be prevented from going up and down between the time when the car stops and the time when the door is opened. When the car goes up and down from the stop position, the first engaging portion and the second time after the door is closed. By releasing the engagement with the engaging part, the fixation of the car to the stop position is canceled after the person or the object gets on and off the car completely, so while the person or the object gets on or off the car, It is possible to ensure that the car is neither raised nor lowered from the stop position.

以下、この発明の実施の形態を添付図面に基づいて説明する。
この発明の実施の形態に係る安全装置が設けられたエレベータの正面図を図１に示す。エレベータ１は、立体駐車場等に設けられた、自動車を昇降するための油圧式エレベータである。エレベータ１は、自動車２を載置するかご３と、かご３が昇降する昇降路４と、かご３を昇降路４に沿って昇降させるための昇降手段である昇降装置５と、昇降路４内で上下方向に延びる２本のガイドレール６，６とから構成されている。かご３の底面には、第１係合部である伸縮可能なピストン部材７が４つ設けられている（図１には、２つのみが図示されている）。昇降路４の内壁面には、各階においてかご３が停止するときに、かご３内の床面３ａと各階の床面９とがほぼ同一面となるような位置（以下、「停止位置」と称する）に、伸びた状態のピストン部材７と係合可能な第２係合部である収容部材８が設けられている。ここで、ピストン部材７及び収容部材８は、安全装置を構成する。 Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 shows a front view of an elevator provided with a safety device according to an embodiment of the present invention. The elevator 1 is a hydraulic elevator provided in a multi-story parking lot or the like for raising and lowering an automobile. The elevator 1 includes a car 3 on which an automobile 2 is placed, a hoistway 4 in which the car 3 moves up and down, an elevating device 5 that is an elevating means for elevating the car 3 along the hoistway 4, and an inside of the hoistway 4 And two guide rails 6 and 6 extending in the vertical direction. Four retractable piston members 7 that are first engaging portions are provided on the bottom surface of the car 3 (only two are shown in FIG. 1). On the inner wall surface of the hoistway 4, when the car 3 stops on each floor, the position where the floor surface 3 a in the car 3 and the floor surface 9 on each floor are substantially flush (hereinafter referred to as “stop position”) The housing member 8 is provided as a second engaging portion that can engage with the extended piston member 7. Here, the piston member 7 and the housing member 8 constitute a safety device.

図２に、エレベータ１の安全装置の拡大側面図を示す。ピストン部材７は、駆動部１１と、駆動部１１によって突出可能なピストン１２と、ピストン１２の先端に固定された円柱形状の挿入部１３とを備えている。収容部材８は、挿入部１３が挿入可能な円筒形状を有しており、収容部材８の内径は、挿入部１３の外径よりも大きく、挿入部１３が収容部材８内に挿入されたときに（図２（ａ））、挿入部１３と収容部材８との間の少なくとも一部に隙間が存在するようになっている。かご３の底面には、入限リミットスイッチ１４及び出限リミットスイッチ１５が設けられている。ピストン１２には、入限リミットスイッチ１４及び出限リミットスイッチ１５に接触可能な接触板１６が固定されている。図２（ａ）に示されるように、挿入部１３が収容部材８内に挿入されたときに、接触板１６が出限リミットスイッチ１５に接触することにより、ピストン部材７と収容部材８とが係合していることを認識するようになっている。一方、図２（ｂ）に示されるように、挿入部１３が収容部材８内にないときに、接触板１６が入限リミットスイッチ１４に接触することにより、ピストン部材７と収容部材８とが係合していないことを認識するようになっている。   FIG. 2 shows an enlarged side view of the safety device of the elevator 1. The piston member 7 includes a drive unit 11, a piston 12 that can project by the drive unit 11, and a columnar insertion unit 13 that is fixed to the tip of the piston 12. The housing member 8 has a cylindrical shape into which the insertion portion 13 can be inserted. The inner diameter of the housing member 8 is larger than the outer diameter of the insertion portion 13, and the insertion portion 13 is inserted into the housing member 8. 2 (FIG. 2A), a gap is present at least at a part between the insertion portion 13 and the housing member 8. An entrance limit switch 14 and an output limit switch 15 are provided on the bottom surface of the car 3. A contact plate 16 that can contact the limit limit switch 14 and the limit limit switch 15 is fixed to the piston 12. As shown in FIG. 2A, when the insertion portion 13 is inserted into the housing member 8, the contact plate 16 comes into contact with the limit limit switch 15, whereby the piston member 7 and the housing member 8 are brought into contact with each other. It is designed to recognize that it is engaged. On the other hand, as shown in FIG. 2B, when the insertion portion 13 is not in the housing member 8, the contact plate 16 contacts the entry limit switch 14, thereby causing the piston member 7 and the housing member 8 to move. It is designed to recognize that it is not engaged.

図３に、昇降装置５の構成模式図を示す。昇降装置５は、エレベータ１のかご３（図１参照）を昇降するためのシリンダ部材２１と、シリンダ部材２１にオイルを供給するためのポンプ部材２２と、シリンダ部材２１とポンプ部材２２とを連通するオイル流通経路２３とを備えている。オイル流通経路２３には、オイル遮断部２４及びオイル流通部２５のいずれか一方をオイル流通経路２３に切り替え可能に組み込む昇降手段安全装置２０が設けられている。オイル遮断部２４は、互いに反対方向にオイルが流通可能になるように設けられた２つの逆止弁２４ａ，２４ｂを備えている。オイル遮断部２４がオイル流通経路２３に組み込まれている場合、ポンプ部材２２からのオイルは逆止弁２４ｂを流通するものの逆止弁２４ａがポンプ部材２２からのオイルを遮断するので、シリンダ部材２１にはオイルが供給されない。一方、シリンダ部材２１からポンプ部材２２に向かって逆流するオイルは、逆止弁２４ａを流通するものの逆止弁２４ｂによって遮断されるので、シリンダ部材２１からポンプ部材２２に向かっての逆流は起こらない。これにより、シリンダ部材２１は停止された状態になり、かご３の昇降が防止されることになる。一方、オイル流通部２５がオイル流通経路２３に組み込まれている場合、オイルは、シリンダ部材２１とポンプ部材２２との間をいずれの方向に向かっても流通可能であり、シリンダ部材２１によるかご３の昇降が可能となる。   In FIG. 3, the structure schematic diagram of the raising / lowering apparatus 5 is shown. The lifting device 5 communicates the cylinder member 21 for lifting and lowering the car 3 (see FIG. 1) of the elevator 1, the pump member 22 for supplying oil to the cylinder member 21, and the cylinder member 21 and the pump member 22. And an oil distribution path 23 that performs the operation. The oil circulation path 23 is provided with an elevating means safety device 20 that incorporates one of the oil blocking part 24 and the oil circulation part 25 so as to be switchable to the oil circulation path 23. The oil shut-off portion 24 includes two check valves 24a and 24b provided so that oil can flow in directions opposite to each other. When the oil blocking part 24 is incorporated in the oil circulation path 23, the oil from the pump member 22 flows through the check valve 24 b, but the check valve 24 a blocks the oil from the pump member 22. No oil is supplied to the. On the other hand, the oil flowing backward from the cylinder member 21 toward the pump member 22 flows through the check valve 24a but is blocked by the check valve 24b, so that no reverse flow from the cylinder member 21 toward the pump member 22 occurs. . Thereby, the cylinder member 21 will be in the stopped state, and the raising / lowering of the cage | basket | car 3 will be prevented. On the other hand, when the oil circulation part 25 is incorporated in the oil circulation path 23, the oil can flow between the cylinder member 21 and the pump member 22 in any direction. Can be moved up and down.

次に、この発明に係るエレベータの安全装置の動作を、図１〜３に基づいて説明する。
かご３を昇降させるためには、昇降装置５において、オイル流通部２５をオイル流通経路２３に組み込まれた状態にする。ポンプ部材２２からシリンダ部材２１にオイルが供給されると、シリンダ部材２１はかご３を上昇させ、逆にシリンダ部材２１からポンプ部材２２にオイルが戻されると、シリンダ部材２１はかご３を下降させる。 Next, the operation of the elevator safety device according to the present invention will be described with reference to FIGS.
In order to raise and lower the car 3, in the lifting device 5, the oil circulation part 25 is set in a state incorporated in the oil circulation path 23. When oil is supplied from the pump member 22 to the cylinder member 21, the cylinder member 21 raises the car 3. Conversely, when oil is returned from the cylinder member 21 to the pump member 22, the cylinder member 21 lowers the car 3. .

かご３が、任意の階の停止位置に停止したら、昇降装置５において、オイル遮断部２４をオイル流通経路２３に組み込まれた状態にする。これにより、昇降手段安全装置２０が安全に機能する限りは、シリンダ部材２１がかご３を昇降させることはない。これと同時に、ピストン部材７において、駆動部１１がピストン１２を突出させて挿入部１３を収容部材８内に挿入させることにより、ピストン部材７と収容部材８とが係合する。このとき、接触板１６が出限リミットスイッチ１５に接触することにより、ピストン部材７と収容部材８とが係合していることを認識する。ピストン部材７と収容部材８との係合が認識されたら、エレベータ１の図示しないドアが開き、かご３から自動車２を降ろしたり、かご３に自動車２を納入したりすることが可能になる。ピストン部材７と収容部材８とが係合することにより、万が一昇降手段安全装置２０が故障したときでも、ドアが開いている間にかご３が昇降するのを防止することができる。   When the car 3 stops at a stop position on an arbitrary floor, the lifting / lowering device 5 brings the oil blocking portion 24 into a state where it is incorporated in the oil circulation path 23. Thereby, as long as the lifting / lowering means safety device 20 functions safely, the cylinder member 21 does not raise or lower the car 3. At the same time, in the piston member 7, the drive unit 11 projects the piston 12 and inserts the insertion unit 13 into the housing member 8, whereby the piston member 7 and the housing member 8 are engaged. At this time, when the contact plate 16 contacts the limit limit switch 15, it is recognized that the piston member 7 and the housing member 8 are engaged. When the engagement between the piston member 7 and the housing member 8 is recognized, the door (not shown) of the elevator 1 is opened, and the car 2 can be lowered from the car 3 or the car 2 can be delivered to the car 3. The engagement of the piston member 7 and the housing member 8 can prevent the car 3 from moving up and down while the door is open even if the lifting / lowering means safety device 20 breaks down.

かご３から自動車２を降ろした後、あるいはかご３に自動車２を納入した後、エレベータ１のドアを閉める。ドアが完全に閉まったら、ピストン部材７において、駆動部１１がピストン１２を引き込み、挿入部１３を収容部材８内から引き抜くことにより、ピストン部材７と収容部材８との係合が解除される。また、これと同時に、昇降装置５において、オイル流通部２５をオイル流通経路２３に組み込まれた状態にすることにより、シリンダ部材２１とポンプ部材２２との間のオイルの流通が可能になるので、シリンダ部材２１はかご３を昇降させることができ、かご３を任意の他の階に移動させることができる。   After unloading the car 2 from the car 3 or delivering the car 2 to the car 3, the door of the elevator 1 is closed. When the door is completely closed, in the piston member 7, the driving portion 11 pulls the piston 12 and the insertion portion 13 is pulled out from the housing member 8, whereby the engagement between the piston member 7 and the housing member 8 is released. At the same time, in the elevating device 5, the oil flow between the cylinder member 21 and the pump member 22 becomes possible by setting the oil flow portion 25 in the oil flow path 23. The cylinder member 21 can raise and lower the car 3 and can move the car 3 to any other floor.

このように、昇降中のかご３が停止する場合には、停止位置にかご３が停止したら、ピストン部材７と収容部材８とが係合され、その後にエレベータ１のドアが開くことにより、かご３が停止してからドアが開くまでの間にかご３が昇降してしまうことを防止でき、かご３が停止位置から昇降する場合には、ドアが閉じた後にピストン部材７と収容部材８との係合が解除されることにより、自動車２のかご３への出入りが完全に終わった後にかご３の停止位置に対する固定が解消されるので、自動車２がかご３に乗り降りする間、確実にかご３を停止位置から上昇も下降もしないようにすることができる。   In this way, when the car 3 that is being lifted / lowered stops, when the car 3 stops at the stop position, the piston member 7 and the housing member 8 are engaged, and then the door of the elevator 1 is opened, whereby the car is opened. It is possible to prevent the car 3 from moving up and down from when the door 3 is opened until the door is opened. When the car 3 is moved up and down from the stop position, the piston member 7 and the housing member 8 By releasing the engagement of the car 2, the car 3 is fixed to the stop position after the car 3 has been completely moved in and out of the car 3. 3 can be prevented from rising or falling from the stop position.

この実施の形態において、ピストン部材７は、かご３の底面に４つ設けられていたが、この形態に限定するものではない。ピストン部材７の個数は任意に変更可能であると共に、ピストン部材７を設ける場所も、かご３の上面や側面であってもよい。また、収容部材８は、昇降路４の内壁面に設けられていたが、ガイドレール等、かご３以外の個所に固定されるように設けられれば、どこに設けてもよい。さらに、ピストン部材７がかご３の底面に設けられると共に収容部材８が昇降路４の内壁面に設けられていたが、これとは逆に、ピストン部材７が昇降路４の内壁面に設けられると共に収容部材８がかご３の底面に設けられてもよい。この場合には、第１係合部が収容部材８であり、第２係合部がピストン部材７である。   In this embodiment, four piston members 7 are provided on the bottom surface of the car 3, but this is not a limitation. The number of the piston members 7 can be arbitrarily changed, and the place where the piston members 7 are provided may be the upper surface or the side surface of the car 3. Moreover, although the accommodating member 8 was provided on the inner wall surface of the hoistway 4, as long as it is provided so that it may be fixed to places other than the cage | basket | car 3, such as a guide rail, it may be provided anywhere. Further, the piston member 7 is provided on the bottom surface of the car 3 and the housing member 8 is provided on the inner wall surface of the hoistway 4. On the contrary, the piston member 7 is provided on the inner wall surface of the hoistway 4. In addition, the housing member 8 may be provided on the bottom surface of the car 3. In this case, the first engaging portion is the accommodating member 8, and the second engaging portion is the piston member 7.

この実施の形態において、収容部材８は、挿入部１３が挿入可能な円筒形状を有していたが、この形態に限定するものではない。例えば、平板状又は平板を任意の形状に屈曲あるいは湾曲したものを、上下方向に間隔をあけて２つ設けたもの（上方にあるものを上方部材といい、下方にあるものを下方部材という）であってもよい。この場合、挿入部１３が上方部材と下方部材との間に位置することにより、収容部材とピストン部材７とが係合したことになる。挿入部１３が上方部材に当接することにより、かご３が上昇することを防止でき、挿入部１３が下方部材に当接することにより、かご３が下降することを防止できる。   In this embodiment, the storage member 8 has a cylindrical shape into which the insertion portion 13 can be inserted, but is not limited to this configuration. For example, a flat plate or a flat plate bent or curved into an arbitrary shape is provided with two spaces in the vertical direction (the upper member is referred to as the upper member and the lower member is referred to as the lower member) It may be. In this case, since the insertion portion 13 is located between the upper member and the lower member, the housing member and the piston member 7 are engaged. The cage 3 can be prevented from rising when the insertion portion 13 abuts against the upper member, and the cage 3 can be prevented from descending when the insertion portion 13 abuts against the lower member.

この実施の形態において、ピストン部材７の駆動部１１がピストン１２を突出させる機構は、機械式、流体式、油圧式等どのような機構のものであってもよい。ただし、この実施の形態において、エレベータ１は油圧式エレベータであることから、昇降装置５に設けられた昇降手段安全装置２０とは異なる機構で駆動することが好ましいので、駆動部１１は、油圧式以外の機構、例えば、機械式または流体式であることが好ましい。ただし、昇降装置５の油圧系とは別の系統の油圧系を用いて駆動部１１を駆動するようにすれば、油圧式の駆動部１１を採用することもできる。   In this embodiment, the mechanism by which the drive unit 11 of the piston member 7 projects the piston 12 may be any mechanism such as a mechanical type, a fluid type, and a hydraulic type. However, in this embodiment, since the elevator 1 is a hydraulic elevator, it is preferable that the elevator 11 is driven by a mechanism different from the lifting / lowering means safety device 20 provided in the lifting / lowering device 5. It is preferable to use a mechanism other than the above, for example, a mechanical type or a fluid type. However, if the drive unit 11 is driven using a hydraulic system different from the hydraulic system of the lifting device 5, the hydraulic drive unit 11 can be employed.

この実施の形態において、エレベータ１は、自動車を昇降するためのものであったが、これに限定するものではない。自動車以外の荷物等を昇降させるエレベータや人が乗るエレベータであってもよい。また、エレベータ１は、油圧式エレベータであったが、これに限定するものではなく、ロープ式エレベータ等、任意のタイプのエレベータであってもよい。   In this embodiment, the elevator 1 is for raising and lowering an automobile, but is not limited to this. It may be an elevator that raises or lowers luggage other than an automobile or an elevator on which a person rides. Moreover, although the elevator 1 was a hydraulic elevator, it is not limited to this, An arbitrary type elevators, such as a rope type elevator, may be sufficient.

尚、この実施の形態において、挿入部１３と収容部材８との間の少なくとも一部に隙間が存在するようにしたのは、かご３が停止位置からほんのわずかずれて停止したとしても、ピストン部材７と収容部材８とが係合できるようにするためである。ただし、この隙間を大きくしすぎると、昇降手段安全装置２０が機能しない場合には、エレベータ１のドアが開いている間、この隙間の範囲内でかご３が昇降してしまい、かご３の床面３ａと停止階の床面９との間に大きな段差が生じてしまうおそれがある。そのため、この段差の許容できる範囲で、隙間の大きさを設計することが好ましい。   In this embodiment, the gap exists in at least a part between the insertion portion 13 and the housing member 8 even if the car 3 is stopped with a slight deviation from the stop position. This is because the housing member 8 can be engaged with the housing 7. However, if this clearance is too large, if the elevator safety device 20 does not function, the car 3 moves up and down within the clearance while the door of the elevator 1 is open, and the floor of the car 3 There is a possibility that a large step is generated between the surface 3a and the floor surface 9 of the stop floor. Therefore, it is preferable to design the size of the gap within an allowable range of the step.
