Description

この発明は、エレベータの乗場とかごの敷居間隔を可変式としたエレベータの敷居装置に関するものである。   The present invention relates to an elevator sill apparatus in which the elevator platform and the car sill interval are variable.

最近、世の中は老齢者の人口が増加している。そのため老人や身障者に優しいバリヤフリー化が進んでいる。エレベータにおいても、かごの敷居と乗場の敷居による躓き事故を減らすため、敷居間隔を小さくする要望が多くなっている。しかし、かごと乗場の敷居間にはかごの戸と乗場の戸を係合する係合装置があるため、敷居間隔を安易に小さくすると、係合装置が相手の敷居と干渉したり、或いはまた係合代が少なくて係合が外れる恐れがある。
また、従来の技術として、最下階において、簡単な構成で、乗場の敷居とかごの敷居との間隙を縮小し、車椅子や台車の車輪、杖などの先端が落ち込む確率を格段に少なくしたエレベータ装置が提案されている（例えば、特許文献１参照）。 Recently, the population of elderly people has increased in the world. For this reason, barrier-free is becoming more and more friendly to the elderly and the disabled. In elevators as well, there is an increasing demand for reducing the threshold interval in order to reduce the number of accidents caused by car thresholds and landing thresholds. However, there is an engagement device that engages the car door and the landing door between the car and the landing sill, so if the sill interval is easily reduced, the engaging device may interfere with the opponent's sill, or There is a possibility that the engagement is small and the engagement is disengaged.
Also, as a conventional technology, an elevator with a simple structure on the lowest floor that reduces the gap between the platform sill and the car sill, and significantly reduces the probability that the tips of wheelchairs, cart wheels, canes, etc. will fall. An apparatus has been proposed (see, for example, Patent Document 1).

特開２００３−８１５６２号公報（図４）Japanese Patent Laying-Open No. 2003-81562 (FIG. 4)

従来のエレベータ装置では、最下階の敷居部分は戸係合装置が敷居部分まで降りてこないので、最下階のみ敷居間隔を小さくしたものであるが、中間階では依然として敷居間隔を小さくすることはできない。また、それ以外にも戸係合装置をやめて敷居間隔を小さくしたものもあるが、構造が複雑化する等の問題があった。   In the conventional elevator system, the door engaging device does not go down to the sill part of the sill part of the lowest floor, so the sill distance is reduced only on the bottom floor, but the sill distance is still reduced on the intermediate floor. I can't. In addition to this, there is a device in which the door engaging device is stopped and the threshold interval is reduced, but there is a problem that the structure becomes complicated.

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、かごの戸が戸開した時にかごと乗場の敷居間隔を小さくすることが可能なエレベータの敷居装置を提供することを目的とする。   This invention was made in order to solve the above problems, and it is an object of the present invention to provide an elevator sill apparatus that can reduce the sill interval of a car and a landing when a car door is opened. To do.

この発明に係るエレベータの敷居装置は、かご床の乗場側端部に設けられた固定式かご敷居と、固定式かご敷居の乗場側前端部に前後方向に進退自在に設けられた可動式かご敷居と、乗場床の昇降路側端部に設けられた固定式乗場敷居と、固定式乗場敷居の昇降路側前端部に前後方向に進退自在に設けられた可動式乗場敷居と、可動式かご敷居及び可動式乗場敷居にそれぞれ設けられ、戸開時に可動式かご敷居及び可動式乗場敷居をそれぞれ突出位置に摺動可能とし敷居の間隔を狭める方向に移動させる摺動ガイドと、可動式かご敷居及び可動式乗場敷居にそれぞれ設けられ、戸閉時やエレベータ走行中、可動式かご敷居及び可動式乗場敷居を引き込み位置に引き込めて敷居の間隔を広げる方向に移動させる戻しバネとを備えたものである。   The elevator sill device according to the present invention includes a fixed car sill provided at a landing side end portion of a car floor, and a movable car sill provided at a front end portion of a fixed car sill in a forward and backward direction. A fixed landing sill provided at the hoistway side end of the landing floor, a movable landing sill provided in the front end of the hoistway side of the fixed landing sill so as to be movable back and forth, a movable car sill and movable A sliding guide that is provided on each type of platform sill, and that can be moved in a direction that allows the movable cage sill and the movable platform sill to slide to projecting positions when the door is opened, and to move the interval between the sills. Each of the landing sills is provided with a movable spring sill and a return spring that retracts the movable sill sill to the retracted position and moves the sill in the direction of widening when the door is closed or during elevator travel.

この発明によれば、エレベータのかご走行中は敷居間隔を一般のエレベータ並みに確保して、戸開した時は自動的に敷居間隔を小さくすることができる。   According to the present invention, it is possible to ensure the threshold interval as in a general elevator while the elevator is traveling and to automatically reduce the threshold interval when the door is opened.

A roller 14 is provided. 15 is a landing roller attachment arm attached to the lower end of the hoistway side (cage side) of the landing door 7 and the opposite door end, and a landing guide roller 16 is provided at the tip of the arm. . Reference numeral 17 denotes a car-side guide rail provided on the upper end of the movable car sill 4a on the door pocket end side. The car-side guide roller 14 is accommodated in an engaged state and guided according to the opening and closing of the car door 3. . 18 is a guide rail on the landing side provided at the upper part of the door end side of the movable landing threshold 8a. The guide roller 16 on the landing side is accommodated in an engaged state and guided according to the opening and closing of the landing door 7. .

すなわち、かご敷居４及び乗場敷居８の先端部に設けられた可動式かご敷居４ａ及び可動式乗場敷居８ａを摺動ガイド４ｄ、８ｄにより摺動可能に構成する。そして、摺動ガイド４ｄ、８ｄには敷居先端の可動範囲を規制するストッパーの凸部４ｃ、４ｅ、８ｃ、８ｅが形成され、可動式敷居の前後の可動範囲を規制している。また、可動式敷居先端の摺動ガイド４ｄ、８ｄの押さえ部分は凹溝部４ｈ、８ｈが形成され敷居先端の横方向の位置を規制している。   That is, the movable cage sill 4a and the movable platform sill 8a provided at the front ends of the car sill 4 and the landing sill 8 are configured to be slidable by the sliding guides 4d and 8d. The sliding guides 4d and 8d are formed with convex portions 4c, 4e, 8c, and 8e that restrict the movable range at the tip of the sill, and restrict the movable range before and after the movable sill. Further, concave portions 4h and 8h are formed in the pressing portions of the sliding guides 4d and 8d at the movable sill tip, thereby restricting the lateral position of the sill tip.

可動式敷居先端の出入口の外側（戸袋部）の上面にはガイドレール１７、１８を備え、これらガイドレール１７、１８に嵌り合うガイドコロ１４、１６を戸の下端部に備え、戸を開くと、図９に示すように、ガイドコロ１４、１６がガイドレール１７、１８を押すことにより、各敷居先端を敷居の間隔を狭める方向に移動させる（図４、図７参照）。これにより、乗場敷居とかご敷居の間隔ｇ２が狭くなるため、乗客乗り込み時は敷居間隔が狭く、乗客は乗り降りし易く、躓く恐れのないエレベータとすることができる。
また、エレベータ走行中は戸を閉じられているので、図８に示すように、ガイドコロ１４、１６はガイドレール１７、１８を押すこともなく、戻しバネ４ｂ、８ｂにより、各敷居先端を敷居の間隔を広げる方向に移動させる（図２、図３参照）。これにより、乗場敷居とかご係合代（咥え代）を充分に確保することができるので、係合装置と敷居の干渉を気にしなくてもよいものとなる。 When guide rails 17 and 18 are provided on the upper surface of the outer side of the entrance / exit of the movable sill (door pocket), guide rollers 14 and 16 fitted to the guide rails 17 and 18 are provided at the lower end of the door, and the door is opened. As shown in FIG. 9, the guide rollers 14 and 16 push the guide rails 17 and 18 to move the tip ends of the sills in the direction of narrowing the sill interval (see FIGS. 4 and 7). Thereby, since the space | interval g2 of a boarding sill and a car sill becomes narrow, it can be set as the elevator which a sill space | interval is narrow at the time of passenger boarding, a passenger is easy to get on and off, and there is no fear of going on.
Further, since the door is closed during the traveling of the elevator, the guide rollers 14 and 16 do not push the guide rails 17 and 18 as shown in FIG. Is moved in the direction of widening the interval (see FIGS. 2 and 3). Thereby, the landing sill and the car engagement allowance (bare allowance) can be sufficiently secured, so that it is not necessary to worry about the interference between the engagement device and the sill.

この実施の形態１によれば、かご敷居及び乗場敷居の戸の脚のガイド溝より先端部のみ可動式敷居とする構成なので、先端部が可動する時は、乗客から見ると、戸の向こう側なので、可動部の乗客の足等が挟まれることがないため、安全に敷居間隔を狭くすることができる。   According to the first embodiment, since only the tip part is movable from the guide groove of the door sill of the car sill and the landing sill, when the tip part moves, when viewed from the passenger, the other side of the door Therefore, since the passenger's foot of the movable part is not caught, the threshold interval can be narrowed safely.
