Description

この発明は、エレベータのかご出入口の床部下面に設けられるエレベータのエプロン装置に関するものである。   The present invention relates to an apron device for an elevator provided on a floor lower surface of an elevator car entrance.

エレベータでは、エレベータのかごの着床誤差により生じるかご床と乗場床との間の空間を塞ぐために、かご出入口の床部下面に前垂れ状のエプロン装置が設けられている。
従来のエレベータのエプロン装置においては、かご出入口の床部下面から下方へ伸びた上部パネルと、上部パネルに連結され、上部パネルに対してスライド可能な下部パネルとを有している。上部パネルは、パネル本体部と、パネル本体部の幅方向端部に設けられ、かごの奥行き方向へ延びるパネル端面部とを有している。パネル端面部には、上下方向へ延びた長穴が設けられている。下部パネルには、長穴に挿入されたガイドボルトが取り付けられている。下部パネルは、ガイドボルトの長穴内での摺動により上部パネルに対してスライド可能になっている（例えば、特許文献１参照）。 In an elevator, in order to close a space between a car floor and a landing floor caused by the landing error of the elevator car, a forward apron device is provided on the lower surface of the floor of the car doorway.
A conventional elevator apron device has an upper panel extending downward from the lower surface of the floor of the car doorway, and a lower panel connected to the upper panel and slidable with respect to the upper panel. The upper panel has a panel main body portion and a panel end surface portion provided at the width direction end portion of the panel main body portion and extending in the depth direction of the car. An elongated hole extending in the vertical direction is provided in the panel end surface portion. Guide bolts inserted into the long holes are attached to the lower panel. The lower panel is slidable with respect to the upper panel by sliding within the elongated hole of the guide bolt (see, for example, Patent Document 1).

従来のエレベータのエプロン装置では、下部パネルの下端部が昇降路のピット底面と当たることで、下部パネルがスライド移動してエプロン装置の全高が縮むことになるので、昇降路内の空間を有効に利用することができる。しかしながら、エプロン装置のピット底面と当たる部分が、下部パネルの下端部全域と広く、ピット底面の傾き等によっては下部パネルの下端部中央部ではなく、中央から外れた端部が当たる可能性がある。このような場合、重心（中央）から遠い端部がピット底面と当たると、エプロン装置のスライド部に回転力が発生し、エプロン装置の上下方向の動きを阻害し、エプロン装置が破損に至る可能性があるという問題があった。   In a conventional elevator apron device, the lower panel of the lower panel hits the bottom of the pit of the hoistway, so the lower panel slides and the overall height of the apron device shrinks, making space in the hoistway effective. Can be used. However, the part of the apron device that hits the bottom of the pit is wide across the lower end of the lower panel, and depending on the inclination of the bottom of the pit, the lower part of the lower panel may hit the end that is off the center. . In such a case, if the end far from the center of gravity (center) hits the bottom of the pit, a rotational force is generated in the slide part of the apron device, obstructing the vertical movement of the apron device, and the apron device can be damaged. There was a problem of having sex.

この発明は上記のような課題を解決するためになされたもので、下部パネルの下端中央部が昇降路のピット底面と当たるようにすることにより、エプロンスライド部に回転力が発生せず、エプロン装置の上下方向の動きを阻害しないエレベータのエプロン装置を提供するものである。   The present invention has been made to solve the above-described problems. By making the bottom center of the lower panel come into contact with the bottom surface of the pit of the hoistway, the apron slide portion does not generate rotational force, and the apron An elevator apron device that does not hinder the vertical movement of the device is provided.

この発明に係るエレベータのエプロン装置は、エレベータのかご出入口の床部下面から下方へ垂直方向に伸びた上部パネルと、上部パネルの下端部に垂直方向に伸びるように連結され、上部パネルに対してスライド可能な下部パネルとを備え、下部パネルの下端部が昇降路のピット底面と当たることで、下部パネルがスライド移動して全高が縮むように構成されたものにおいて、下部パネルの下端中央部に設けられ、他の部分よりも出っ張って昇降路のピット底面に当たる突き当たり部を備え、突き当たり部はかごの奥行き方向に向かって傾斜して伸びているものである。 Apron device for an elevator according to the present invention comprises a top panel extending vertically downward from the floor lower surface of the car entrance of elevator is connected so as to extend in the vertical direction to the lower end of the top panel, with respect to the top panel It is provided with a slidable lower panel, and the lower panel is configured to slide so that its overall height contracts by the lower end of the lower panel hitting the bottom of the pit of the hoistway. In addition, a bumping portion that protrudes from the other portion and hits the bottom surface of the pit of the hoistway is provided , and the bumping portion is inclined and extends in the depth direction of the car .

この発明によれば、上下方向に摺動するエプロン可動部である下部パネルの重心真下付近であるエプロン下端中央部で昇降路のピット底面に当たるので、スライド部分に回転力が発生せず、スムーズにエプロン可動部が上下方向に動くことができるという効果がある。また、突き当たり部はかごの奥行き方向に向かって傾斜して伸びているので、昇降路のピット底面に当たった場合の衝撃が緩和されるという効果がある。 According to the present invention, since the apron lower end central portion near the center of gravity of the lower panel, which is the apron movable portion that slides in the vertical direction, hits the bottom of the pit of the hoistway, no rotational force is generated in the slide portion, and smooth There is an effect that the apron movable part can move in the vertical direction. Further, since the abutting portion extends while inclining in the depth direction of the car, there is an effect that the impact when it hits the pit bottom surface of the hoistway is reduced.

Reference numeral 3a denotes an upper panel of the panel device, which constitutes an apron fixing portion that does not move in the vertical direction. Reference numeral 3b denotes a lower panel that is connected to the lower end of the upper panel 3a and is slidable with respect to the upper panel 3a, and constitutes an apron movable section that moves in the vertical direction. The upper panel 3a is manufactured by bending a metal plate so that the horizontal cross section has a U-shape, and extends downward from the entrance / exit of the car floor 1, and the widthwise end of the panel main body 3c. And a pair of left and right panel end surface portions 3d extending in the depth direction of the car. The panel body 3c is arranged in parallel to the width direction of the car doorway. Each panel end surface part 3d is provided over the whole height direction of the panel main-body part 3c. Further, two guide bolts 3e are attached to each panel end surface portion 3d with a space in the vertical direction. The lower panel 3b includes a plate-like front part 3f partially superposed on the panel main body part 3c, and a pair of left and right end parts extending in the width direction of the front part 3f and extending in the depth direction of the car. 3g. The width of the front portion 3f is larger than the width of the panel body 3c. Further, the pair of left and right panel end surface portions 3d are disposed between the end extending portions 3g. Each end extension 3g is provided with a long hole 3h which is a guide means extending in the vertical direction. Then, when the guide bolt 3e slides in the elongated hole 3h, the lower panel 3b is guided in the vertical direction along the elongated hole 3h. Note that a low friction material for smooth sliding of the guide bolt 3e may be provided on the inner surface of the elongated hole 3h.
