Description

技術分野
本発明は、乗場及び乗かごのドアが横方向に開閉するエレベータ装置に係り、特に、ドアの開閉を案内する乗場側のシル（敷居）とかご側のシルとの間隔を狭めたエレベータ装置に関する。
背景技術
一般に乗場ドアは、乗かごに搭載された駆動機によって駆動されるかごドアと連動して開閉動作を行うために、乗かごが着床した際に乗場ドアとかごドアとが係合するように、相手側ドア側へ夫々突出する係合装置が設けられている。この係合装置が昇降時に各シルと干渉しないように、乗場側シルとかご側シルとの間隔を大きくしていた。しかし、乗場側シルとかご側シルとの間隔が大きくなると、車椅子等の車輪が乗場側シルとかご側シルとの間に落ち込んだり、乳幼児の足がはまり込んだりする危険がある。
そこで、乗場側シルとかご側シルとの間隔を可能な限り狭めようと、例えば特開昭６０−１４８８８４号公報に開示のように、垂直投影において上記係合装置が設けられている部分の乗場側シルとかご側シルの対向部分に凹凸を形成する技術が存在する。
上記乗場側シルとかご側シルの対向部分に凹凸を形成する従来の技術は、両シルの間隔が狭くなったので上記問題を解消できる利点はある。しかし、両シルの間隔が狭くなった分、地震等で乗かごが揺れた場合、両シルが凹凸部で衝突してシルを変形させる危険がある。また、乗りかごの昇降中に係合装置を作動させると、係合装置が凹凸部に干渉してしまう危険もある。したがって、こうした場合にシル全体を交換しなければならない、という新たな問題について配慮されていなかった。
発明の開示
本発明の目的は、シルの凹凸部が互いに衝突したり、係合装置と衝突したりしても、損害を最小限に留めることができるエレベータ装置を提供することにある。
本発明は上記目的を達成するために、乗場ドアとかごドアを夫々横方向に移動案内する乗場側シルとかご側シルの一方に、前記乗場ドアとかごドアとを互いに係合させる係合装置の垂直投影と離間する凹部を形成し、乗場側シルとかご側シルの他方に前記凹部内で互いの垂直投影が離間する凸部を形成し、これら凹部または凸部の少なくとも一方の前記ドア移動方向の端部に保護部材を設けたのである。
上記構成によれば、地震等で乗かごが揺れて両シル同士が凹凸部で衝突したり、係合装置が作動して凹凸部に干渉したりしても、衝突するのは保護部材であり、仮に保護部材が破損しても保護部材のみ交換すればよいので、シル全体を交換する必要は無くなる。
発明を実施するための最良の形態
以下、本発明の一実施形態を第１図〜第４図に基づいて説明する。一般に、エレベータ装置は、建築物１に垂直に設けられた昇降路２と、この昇降路２内を案内されて昇降するに乗かご３と、この乗かご３を昇降方向に駆動する駆動機械（図示せず）から構成されている。
そして、前記乗かご３は、乗客を乗せるかご室４と、このかご室４の出入口を開閉するかご側ドア５と、かご側ドア５を吊り下げて横方向への移動を案内するドアレール６と、前記かご側ドア５の下端を係合させて上記移動方向に案内する溝７Ｇを有するかごシル７とを備えている。
一方、前記建築物１は、各階床８と昇降路２とを連通する乗降口９と、この乗降口９を前記かご側ドア５と同方向に開閉する乗場側ドア１０と、この乗場側ドア１０を吊り下げて開閉移動を案内するドアレール１１と、前記乗場側ドア１０の下端を係合させて上記移動方向に案内する溝１２Ｇを有する乗場シル１２とを備えている。
さらに、前記乗場側ドア１０の開閉は、かご側ドア５の開閉に連動して行われる。かご側ドア５の開閉は、乗かご２に搭載されたドア駆動機とドア駆動機構（何れも図示せず）とによって行われる。
かご側ドア５と乗場側ドア１０との連動は、乗かご２が階床８に着床したときドア移動方向にのみ係合する係合装置１３が両ドア５，１０に設けられている。この係合装置１３は、例えば第２図に示すように、平面コ字状をなしコ字状の両脚が前記乗場側ドア１０側に向かって突出するようにかご側ドア５に設けられた係合具１４と、前記平面コ字状の係合具１４の両脚間に臨むように前記かご側ドア５に向かって突出するように乗場側ドア１０に設けられた係合ローラ１５とからなる。なお、第２図において、係合ローラ１５は２組設けられている。
ところで、前記係合装置１３の係合ローラ１５は、平面的にかごシル７と重なる位置まで突出しているので、乗かご２の昇降時に、かごシル７が乗場側ドア１０の係合ローラ１５に衝突することになる。これを避けるために、従来においては、かごシル７と乗場シル１２とを平行に対向するようにし、その隙間を２０〜３０ｍｍ確保していた。しかし、本実施の形態によれば、かごシル７には、係合ローラ１５の垂直投影に余裕を持った大きさを許容する凹溝１６を形成すると共に、この凹溝１６を埋めるように乗場シル１２にはほぼ係合ローラ１５の垂直投影に見合った大きさの凸部１７を形成することにより、かごシル７と乗場シル１２間の隙間Ｇ０，Ｇ１，Ｇ２、を略同じの６〜１０ｍｍにすることができる。
そして、かごシル７と乗場シル１２間の隙間が狭くなった分、地震等の揺れにより乗かご２が変位した場合、上記凹凸部が衝突する機会が大きくなるので、上記凹溝１６及び凸部１７が形成する凹凸部の特に前記ドア５あるいは１０の移動方向の端部７Ｓ，１２Ｓに夫々保護部材１８，１９を設けたのである。
このように、保護部材１８，１９を設けることにより、例えば、乗かご２の揺れにより第４図に示すように、凹溝１６端と凸部１７端とが衝突した場合、積極的に保護部材１９を破損させることができるので、その損傷時に衝突エネルギーを減衰させることができる。したがって、かごシル７あるいは乗場シル１２の損傷はなく、保護部材１９あるいは保護部材１８，１９のみを取外して新品と交換するだけでよいので地震後の復旧が容易となる。尚、この保護部材は、凹部または凸部の少なくとも一方の端部に設ける構成であれば、他の実施形態でも構わない。
上記実施の形態は、がごシル７に凹溝１６を形成し、乗場シル１２に凸部１７を形成しているので、それらの形成作業の工程が加わると共に、材料の歩留まりも悪い。
そこで、第５図に示す実施の形態では、前記実施の形態によるかごシル７及び乗場シル１２よりも幅が狭く、しかも全長に亘って同一幅のかごシル７Ａ及び乗場シル１２Ａとし、これらかごシル７Ａと乗場シル１２Ａとの対向部に夫々補助かごシル７Ｂと補助乗場シル１２Ｂを取付けるようにしたのである。即ち、かごシル７Ａには、２つの補助かごシル７Ｂを間隔を空けて取付けることにより、２つの補助かごシル７Ｂ間とかごシル７Ａとで凹溝１６を形成し、乗場シル１２Ａには、１つの補助乗場シル１２Ｂを前記２つの補助かごシル７Ｂ間に臨むように取付けるのである。そして、これら補助かごシル７Ｂと補助乗場シル１２Ｂに保護部材１８，１９を取付けるのである。尚、凹部または凸部の少なくとも一方を、これら補助シルにより形成する構成であれば、他の実施形態でも構わない。
このように補助かごシル７Ｂと補助乗場シル１２Ｂによって凹溝１６と凸部１７を形成することによって、各シルの形成が容易になると共に、各シルの形状が単純になるので、材料の歩留まりも向上する。
ところで、前記保護部材１８，１９は、かごシル７及び乗場シル１２と同材質として、前記凹溝１６と凸部１７に着脱可能に取付けてもよいが、衝突時のエネルギーを吸収し易くするために、かごシル７及び乗場シル１２よりも破損し易い、いい代えればかごシル７及び乗場シル１２よりも衝撃強度の低い材料、例えばポリアミド樹脂等の合成樹脂製や低摩擦材で形成することが望ましい。
また、前記保護部材１８，１９は、接着やねじ止め等により取付けてもよいが、第６図及び第７図に示すように取付けてもよい。第６図及び第７図は、一例として凸部１７を備えた乗場シル１２を示している。第６図は、保護部材１９に前記凸部１７に向かう取付けピン２０を設け、この取付けピン２０を凸部１７に設けたピン穴２１に矢印で示すように差し込んで取付けるものである。第７図は、保護部材１９に前記乗場シル１２に向かう取付けピン２２を設け、この取付けピン２２を乗場シル１２に設けたピン穴２３に矢印で示すように差し込んで取付けるものである。
次に、第８図，第９図について説明する。ここに示すのは、第５図に示す実施の形態による補助かごシル７Ｂと補助乗場シル１２Ｂに代わる補助かごシル及び補助乗場シルに関するものであるが、個々では一例として乗場シル１２Ａ側の補助乗場シル１２Ｃについて説明する。
ここに示す補助乗場シル１２Ｃは、全体が例えばポリアミド樹脂等の合成樹脂製の保護部材であり、断面コ字状に形成されている。そして断面コ字状の開口部を下向きにして前記乗場シル１２Ａのかごシルとの対向面に固定具１２Ｄを介して取付けたのである。固定具１２Ｄは、乗場シル１２Ａにねじ等の締結手段によって取付けられる。また、固定具１２Ｄは、前記補助乗場シル１２Ｃの開口内に挿入される係合部を有し、この係合部と乗場シル１２Ａとによって補助乗場シル１２Ｃを挟み込むのである。
上記各実施の形態は、乗かご２が着床時に、この乗かご２がドアの開閉方向に揺れた場合の各シルの損傷を防止するものであるが、乗かご２はドアの開閉方向と直交する方向にも揺れる。乗かご２が揺れてかごシル７，７Ａと乗場シル１２，１２Ａ間の隙間が狭くなって衝突した場合、その衝突部はかごシル７，７Ａと乗場シル１２，１２Ａの略全長に亘るので、衝突力が集中せずに分散されるので、シルを変形させるような損傷はない。
しかし、乗かご２が昇降中に、乗かご２がドアの開閉方向と直行する方向に揺れた場合には、第１０図に示すように、各シル７，１２の底部から下方に延在した転落防止用トーガード２４，２５に夫々各シル７，１２の端部から下向きに傾斜した傾斜部２４Ｓ，２５Ｓを設けておくことにより各シルの損傷を防止することができる。即ち、第１０図は、かごシル７が乗場シル１２に対して下側に位置し、両シル間が乗かごの揺れにより狭くなっている状態を示している。この状態で、乗かごが上昇すると、両シルは衝突してしまうが、両シルの衝突の前に、かごシル７の先端が乗場側のつま先保護用トーガード２５の傾斜部２５Ｓに接触し、乗かごを乗場側とは反対側に案内するので両シルが直接衝突することはない。尚、かごシル７の先端がつま先保護用トーガード２５の傾斜部２５Ｓに接触することにより、傾斜部２５Ｓは変形するが、この変形により衝突力を吸収して両シル７，１２の変形を防止できるのである。
逆に、乗かごが乗場シル１２の上方から下降している途中に乗かごが揺れて両シル７，１２間の隙間が狭くなった場合には、かごシル７側の転落防止用エプロン２４の傾斜部２４Ｓが乗場シル１２の先端に衝突して乗かごを乗場側とは反対側に案内すると共に、変形して衝突力を吸収する。
したがって、転落防止用エプロン２４，つま先保護用トーガード２５の傾斜部２４Ｓ，２５Ｓは、両シル７，１２よりも強度的に弱い形状や材質で形成するとよい。
補助シルの一部に保護部材を設ける、更に別の実施例について、第１１図〜第１５図を用いて説明する。第１１図のように、補助乗場シル１２Ｅの基盤１２Ｆをアクリル等の樹脂で形成し、表面を基盤１２Ｆとは別の材質としてステンレスまたはアルミで形成される意匠材１２Ｈで覆う構成としている。これは、補助乗場シル１２Ｅの表面を乗場シル１２Ａの表面と同じ材質とすることにより、第１２図のように利用者の目から見て意匠的に違和感のないようにするためである。同じ材質でなくても意匠的な問題をクリアできるものであれば、どんなもので補助乗場シル１２Ｅの表面を覆っても良い。尚、本実施例では、第１２図に示すように乗場シル１２側に補助シルを設けて凸状とし、かごシル７側は補助シルを設けずにかごシル７自体を凹状に形成し、ドア移動方向の端部に保護部材１８を取り付けた。
そこで、補助乗場シル１２Ｅの基盤１２Ｆの構成について、詳細に説明する。第１１図のように、この補助乗場シル基盤１２Ｆは、Ｌ字状に形成されており、一端が乗場シル１２Ａの側面にボルト３０を介して着脱可能に固定されている。また、折り曲がる部分が、第１３図に示すようなリブ２６により支持されている。このリブ２６は、樹脂形成時にひけによるひずみを少なくするよう、ドアの開閉方向に断続的に構成されている。
また、補助乗場シル１２Ｅに一定の荷重、例えば２００〜３００キログラムの重さがかかったときに、Ｌ字の折り曲がった部分に亀裂が入るなどして壊れるように構成されている。これは、通常の荷物を積んだ台車や人が踏んだ場合でも壊れないが、エレベータの係合装置１３が衝突した場合等の強力な力が加わった場合に壊れるようにしたためである。すると、補助乗場シル基盤１２Ｆを優先的に壊し、シルの損傷を防ぐことが可能となる。尚、必要な場合には、第１１図に示すように、補助乗場シル基盤１２Ｆに予め切欠き２７を設けておいて、その部分で積極的に壊れるようにしても良い。勿論、切欠き２７を設ける位置としては、第１１図の位置に限るものではない。
また、第１４図のように、補助シルトーガード２８とシルトーガード２９とがそれぞれ別々の部品により構成され、別々に固定されているので、補助シルが壊れたときでも、補助シルトーガード２８だけを破棄すれば、シルと共にシルトーガード２９をそのまま継続して利用することができる。
尚、本実施例では、乗場シル側に補助乗場シル１２Ｅを設ける構成について述べたが、第１６図に示すように、かごシル側についても、かごシル７Ａに補助かごシル７Ｅ（７Ｆ，７Ｈ）を２つ設けて凹状の構成にして良い。また、乗場シル側を凸状でなくて凹状に構成しても構わない。
更に、凹部のみを、補助シルにより形成する構成であっても良い。

Relates to the device.
Background Art In general, a landing door opens and closes in conjunction with a car door driven by a drive mounted on the car, so that the landing door and the car door are engaged when the car is landed. Thus, the engaging device which protrudes to the other party door side is provided. The distance between the landing-side sill and the car-side sill has been increased so that the engaging device does not interfere with each sill during elevation. However, if the distance between the landing sill and the car sill increases, there is a risk that the wheel of a wheelchair or the like falls between the landing sill and the car sill or the infant's foot gets stuck.
Therefore, in order to narrow the distance between the landing-side sill and the car-side sill as much as possible, for example, as disclosed in Japanese Patent Application Laid-Open No. 60-14884, a landing at a portion where the above-described engagement device is provided in vertical projection There is a technique for forming irregularities in the opposing portions of the side sill and the car side sill.
The conventional technique for forming irregularities in the facing portion between the landing-side sill and the car-side sill has an advantage that the above problem can be solved because the distance between both sills is reduced. However, if the car is shaken due to an earthquake or the like because the distance between the two sills is narrow, there is a risk that both sills will collide with the uneven part and deform the sill. In addition, if the engagement device is operated while the car is moving up and down, there is a risk that the engagement device may interfere with the uneven portion. Therefore, no consideration was given to the new problem of having to replace the entire sill in these cases.
DISCLOSURE OF THE INVENTION An object of the present invention is to provide an elevator apparatus capable of minimizing damage even if the concavo-convex portions of the sill collide with each other or with the engaging device.
In order to achieve the above object, the present invention provides an engagement device for engaging the landing door and the car door with one of the landing side sill and the car side sill for moving and guiding the landing door and the car door in the lateral direction. A concave portion that is spaced apart from the vertical projection is formed, and a convex portion is formed on the other of the landing-side sill and the cage-side sill and the vertical projections are separated from each other within the concave portion, and the door movement of at least one of these concave portions or the convex portion A protective member is provided at the end in the direction.
According to the above configuration, even if the car is shaken by an earthquake or the like and both sills collide with each other at the uneven part, or the engaging device operates and interferes with the uneven part, it is the protective member that collides. Even if the protective member is damaged, it is only necessary to replace the protective member, so there is no need to replace the entire sill.
BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the present invention will be described with reference to FIGS. In general, an elevator apparatus includes a hoistway 2 provided perpendicularly to a building 1, a car 3 that is guided in the hoistway 2 to move up and down, and a drive machine that drives the car 3 in the hoisting direction ( (Not shown).
The car 3 includes a car room 4 in which passengers are placed, a car-side door 5 that opens and closes the entrance of the car room 4, and a door rail 6 that suspends the car-side door 5 and guides movement in the lateral direction. And a car sill 7 having a groove 7G for engaging the lower end of the car-side door 5 and guiding it in the moving direction.
On the other hand, the building 1 includes a boarding gate 9 that communicates each floor 8 and the hoistway 2, a boarding door 10 that opens and closes the boarding door 9 in the same direction as the car-side door 5, and the boarding door. 10 includes a door rail 11 that suspends 10 and guides opening and closing movement, and a landing sill 12 that has a groove 12G that engages the lower end of the landing-side door 10 and guides it in the moving direction.
Further, the landing-side door 10 is opened and closed in conjunction with the opening and closing of the car-side door 5. The car-side door 5 is opened and closed by a door driving machine and a door driving mechanism (both not shown) mounted on the car 2.
As for the linkage between the car-side door 5 and the landing-side door 10, an engagement device 13 that engages only in the door moving direction when the car 2 reaches the floor 8 is provided in both the doors 5 and 10. For example, as shown in FIG. 2, the engaging device 13 has a plane U-shape and is provided on the car-side door 5 so that both U-shaped legs protrude toward the landing-side door 10 side. It consists of a combination tool 14 and an engagement roller 15 provided on the landing side door 10 so as to project toward the car side door 5 so as to face between both legs of the planar U-shaped engagement tool 14. In FIG. 2, two sets of engagement rollers 15 are provided.
By the way, since the engaging roller 15 of the engaging device 13 protrudes to a position where it overlaps the car sill 7 in plan view, the car sill 7 moves to the engaging roller 15 of the landing-side door 10 when the car 2 is raised and lowered. It will collide. In order to avoid this, conventionally, the car sill 7 and the landing sill 12 face each other in parallel, and a clearance of 20 to 30 mm is secured. However, according to the present embodiment, the car sill 7 is formed with the concave groove 16 that allows the vertical projection of the engagement roller 15 to have a sufficient size, and the landing is made to fill the concave groove 16. The sill 12 is formed with a convex portion 17 having a size corresponding to the vertical projection of the engagement roller 15 so that the gaps G 0 , G 1 , G 2 between the car sill 7 and the landing sill 12 are substantially the same. It can be 6 to 10 mm.
Since the gap between the car sill 7 and the landing sill 12 becomes narrower, when the car 2 is displaced due to shaking such as an earthquake, the chance of the bumps colliding increases, so the grooves 16 and the bumps Protective members 18 and 19 are provided on the projections and depressions 17 formed on the doors 7 and 12S in the moving direction of the door 5 or 10, respectively.
Thus, by providing the protective members 18 and 19, for example, when the end of the concave groove 16 and the end of the convex portion 17 collide with each other as shown in FIG. Since the 19 can be broken, the collision energy can be attenuated at the time of the damage. Therefore, there is no damage to the car sill 7 or the landing sill 12, and it is only necessary to remove the protective member 19 or the protective members 18 and 19 and replace them with new ones. In addition, as long as this protection member is the structure provided in the at least one edge part of a recessed part or a convex part, other embodiment may be sufficient.
In the above embodiment, the concave groove 16 is formed in the gill sill 7 and the convex portion 17 is formed in the landing sill 12, so that the process of forming them is added and the material yield is also poor.
Therefore, in the embodiment shown in FIG. 5, the car sill 7A and the landing sill 12A are narrower than the car sill 7 and the landing sill 12 according to the above-described embodiment and have the same width over the entire length. The auxiliary car sill 7B and the auxiliary landing sill 12B are attached to the opposing portions of 7A and the landing sill 12A, respectively. In other words, two auxiliary car sills 7B are attached to the car sill 7A at an interval to form a groove 16 between the two auxiliary car sills 7B and the car sill 7A. The two auxiliary landing sills 12B are attached so as to face between the two auxiliary car sills 7B. The protective members 18 and 19 are attached to the auxiliary car sill 7B and the auxiliary landing sill 12B. In addition, as long as at least one of a recessed part or a convex part is a structure which forms with these auxiliary sills, other embodiment may be sufficient.
Thus, by forming the concave groove 16 and the convex portion 17 by the auxiliary car sill 7B and the auxiliary landing sill 12B, each sill can be easily formed and the shape of each sill is simplified, so that the yield of the material is also increased. improves.
By the way, the protective members 18, 19 may be made of the same material as the car sill 7 and the landing sill 12, and may be detachably attached to the concave groove 16 and the convex portion 17, but in order to easily absorb energy at the time of collision. In addition, it is easier to break than the car sill 7 and the landing sill 12. In other words, it is made of a material having a lower impact strength than the car sill 7 and the landing sill 12, for example, a synthetic resin such as polyamide resin or a low friction material. desirable.
The protective members 18 and 19 may be attached by bonding or screwing, but may be attached as shown in FIGS. 6 and 7 show a hall sill 12 having a convex portion 17 as an example. FIG. 6 shows that a mounting pin 20 directed to the convex portion 17 is provided on the protective member 19 and this mounting pin 20 is inserted into a pin hole 21 provided in the convex portion 17 as indicated by an arrow. FIG. 7 shows that a mounting pin 22 directed to the landing sill 12 is provided on the protective member 19 and this mounting pin 22 is inserted into a pin hole 23 provided in the landing sill 12 as indicated by an arrow.
Next, FIGS. 8 and 9 will be described. 5 shows the auxiliary car sill 7B and the auxiliary hall sill 12B in place of the auxiliary car sill 7B and the auxiliary hall sill 12B according to the embodiment shown in FIG. 5, but as an example, the auxiliary hall on the side of the hall sill 12A is shown as an example. The sill 12C will be described.
The auxiliary landing sill 12C shown here is a protective member made of a synthetic resin such as a polyamide resin as a whole, and is formed in a U-shaped cross section. Then, the opening having a U-shaped cross-section is directed downward and is attached to the surface of the landing sill 12A facing the car sill via a fixture 12D. The fixture 12D is attached to the landing sill 12A by fastening means such as screws. Further, the fixture 12D has an engaging portion inserted into the opening of the auxiliary landing sill 12C, and the auxiliary landing sill 12C is sandwiched between the engaging portion and the landing sill 12A.
In each of the above embodiments, when the car 2 is landed, the sill is prevented from being damaged when the car 2 swings in the door opening / closing direction. It swings in the orthogonal direction. When the car 2 sways and the gap between the car sill 7 and 7A and the hall sill 12 and 12A collides with each other, the collision part extends over substantially the entire length of the car sill 7 and 7A and the hall sill 12 and 12A. Since the collision force is dispersed without being concentrated, there is no damage that deforms the sill.
However, when the car 2 swings in the direction perpendicular to the door opening / closing direction while the car 2 is moving up and down, as shown in FIG. 10, it extends downward from the bottom of each sill 7,12. By providing inclined portions 24S and 25S inclined downward from the ends of the respective sills 7 and 12 in the fall prevention toe guards 24 and 25, damage to the respective sills can be prevented. That is, FIG. 10 shows a state in which the car sill 7 is positioned below the hall sill 12 and the space between both sills is narrowed by the shaking of the car. When the car rises in this state, both sills collide, but before the collision of both sills, the tip of the car sill 7 comes into contact with the inclined portion 25S of the toe protection toe guard 25 on the landing side, Since the car is guided to the opposite side from the landing side, both sills do not collide directly. The inclined portion 25S is deformed by the tip of the car sill 7 coming into contact with the inclined portion 25S of the toe protection toe guard 25. This deformation can absorb the collision force and prevent deformation of both the sills 7 and 12. It is.
On the other hand, when the car swings while the car is descending from the upper side of the landing sill 12 and the gap between the two sills 7 and 12 becomes narrow, the fall prevention apron 24 on the car sill 7 side The inclined portion 24S collides with the tip of the landing sill 12, guides the car to the side opposite to the landing side, and deforms to absorb the collision force.
Therefore, the slopes 24S and 25S of the fall-preventing apron 24 and the toe protection toe guard 25 may be formed of a shape or material weaker in strength than the both sills 7 and 12.
Still another embodiment in which a protective member is provided on a part of the auxiliary sill will be described with reference to FIGS. As shown in FIG. 11, the base 12F of the auxiliary landing sill 12E is formed of a resin such as acrylic, and the surface is covered with a design material 12H formed of stainless steel or aluminum as a material different from the base 12F. This is because the surface of the auxiliary landing sill 12E is made of the same material as the surface of the landing sill 12A, so that the design is not uncomfortable from the user's eyes as shown in FIG. The surface of the auxiliary landing sill 12E may be covered with anything as long as the design problem can be cleared without using the same material. In this embodiment, as shown in FIG. 12, an auxiliary sill is provided on the landing sill 12 side to form a convex shape, and on the car sill 7 side, the auxiliary sill is not provided and the car sill 7 itself is formed in a concave shape. A protective member 18 was attached to the end in the moving direction.
Therefore, the configuration of the base 12F of the auxiliary landing sill 12E will be described in detail. As shown in FIG. 11, the auxiliary landing sill base 12F is formed in an L shape, and one end thereof is detachably fixed to the side surface of the landing sill 12A via a bolt 30. Further, the bent portion is supported by a rib 26 as shown in FIG. The ribs 26 are intermittently configured in the door opening / closing direction so as to reduce distortion due to sink marks during resin formation.
Further, when a certain load, for example, a weight of 200 to 300 kilograms, is applied to the auxiliary landing sill 12E, the auxiliary landing sill 12E is configured to break due to a crack in the bent portion of the L-shape. This is because the vehicle is not broken even when it is stepped on by a carriage or a person loaded with normal luggage, but it is broken when a strong force is applied such as when the engagement device 13 of the elevator collides. Then, it becomes possible to preferentially break the auxiliary landing sill base 12F and prevent damage to the sill. If necessary, as shown in FIG. 11, a cutout 27 may be provided in the auxiliary landing sill base 12F in advance, and the portion may be actively broken. Of course, the position where the notch 27 is provided is not limited to the position shown in FIG.
Further, as shown in FIG. 14, the auxiliary sill toe guard 28 and the sill toe guard 29 are configured by separate parts, and are fixed separately, so even if the auxiliary sill breaks, if only the auxiliary sill toe guard 28 is destroyed, The sill toe guard 29 can be used as it is together with the sill.
In the present embodiment, the structure in which the auxiliary landing sill 12E is provided on the landing sill side has been described. However, as shown in FIG. 16, the auxiliary sill 7E (7F, 7H) is also added to the car sill 7A on the sill side. Two may be provided to form a concave configuration. Further, the landing sill side may be configured to be concave instead of convex.
Furthermore, the structure which forms only a recessed part with an auxiliary | assistant sill may be sufficient.
