Description

本発明は、エレベータの乗場ドア離脱防止装置に関し、より詳しくは、閉じられた状態におけるドア結合力を増強させ、外力により乗場ドアが開放される、また、乗場ドアの開放により事故が発生することを防止することができるエレベータの乗場ドア離脱防止装置に関する。   The present invention relates to an elevator landing door detachment prevention device, and more specifically, the door coupling force in a closed state is increased, the landing door is opened by an external force, and an accident occurs due to the opening of the landing door. The present invention relates to an elevator landing door detachment preventing device that can prevent the above.

一般に、乗場ドアはエレベータの何れの部分より人間の直接的な接触が容易な場所に設けられており、乗客のいたずらや思いがけない事故に直面している。
エレベータで発生する事故において、このような乗場ドアに強い衝撃が加えられた時に乗場ドアとともに客の足が昇降路に向かうことにより発生する事故が相当の割合を占めている。 In general, landing doors are provided in places where direct human contact is easier than any part of the elevator, and face passenger mischief and unexpected accidents.
In an accident that occurs in an elevator, when a strong impact is applied to such a landing door, an accident that occurs when a passenger's foot goes to the hoistway together with the landing door accounts for a considerable proportion.

ここで、製造社等はそれぞれ乗場ドアの強度を補強するなどの措置を取っているが、このような措置は十分でないだけでなく、費用負担も増大する。   Here, manufacturers and the like have taken measures such as reinforcing the strength of the landing doors, but such measures are not only sufficient, but also increase the cost burden.

図１は従来のエレベータのドア構造を示した図であり、図２は図１から一部を抜粋した拡大図、図３は従来のエレベータドアの正常な結合状態を示した側面図、図４は従来のエレベータドアの離脱時の結合状態を示した側面図である。   1 is a view showing a door structure of a conventional elevator, FIG. 2 is an enlarged view of a part extracted from FIG. 1, FIG. 3 is a side view showing a normal coupling state of a conventional elevator door, and FIG. FIG. 6 is a side view showing a coupling state when the conventional elevator door is detached.

図１〜図３に示されているように、一般にエレベータは、乗場に２つ、多くは４つのドアを備え、それぞれの乗場ドア１ａ，１ｂの上部には、連結板２ａ，２ｂが連結される。この連結板２ａ，２ｂが、乗場ドア装置内で互いにワイヤなどで連結されているので、一方のドアが移動すれば、他方のドアも、連結されたワイヤから力が伝えられて移動することができ、これに伴い乗場ドア１ａ，１ｂが開かれるか閉じられる。または、それぞれの連結板２ａ，２ｂがそれぞれ駆動するに伴い、乗場ドア１ａ，１ｂが開かれるか閉じられる。このとき、連結板２ａ，２ｂとレール４２との間には滑車３ａ，３ｂが適用される。   As shown in FIGS. 1 to 3, in general, an elevator is provided with two doors at the landing, mostly four doors, and connecting plates 2a and 2b are connected to the upper portions of the landing doors 1a and 1b. The Since the connecting plates 2a and 2b are connected to each other by wires or the like in the landing door device, if one door moves, the other door can also be moved by a force transmitted from the connected wire. Accordingly, the landing doors 1a and 1b are opened or closed. Alternatively, the landing doors 1a and 1b are opened or closed as the connecting plates 2a and 2b are driven. At this time, pulleys 3a and 3b are applied between the connecting plates 2a and 2b and the rail 42.

図４に示されているように、このような構造で乗場ドア１ａに強い衝撃が加えられ乗場ドア１ａに撓みが発生すれば、ドア１ａの上段に固定されていた連結板２ａが折り曲げられることがあり、これにより連結板２ａに固定されていた滑車３ａがレール４２から離脱される恐れがある。このような滑車３ａの離脱により乗場ドア１ａの上段も離脱されることがあり、これにより転落事故が発生する恐れがある。   As shown in FIG. 4, when a strong impact is applied to the landing door 1a and the landing door 1a is bent with such a structure, the connecting plate 2a fixed to the upper stage of the door 1a is bent. As a result, the pulley 3a fixed to the connecting plate 2a may be detached from the rail 42. Due to such separation of the pulley 3a, the upper stage of the landing door 1a may also be detached, which may cause a fall accident.

本発明は、前記の従来の技術の問題点を解消するためになされたものであり、少ない費用でも大きな離脱防止効果、または離脱を根本的に抑制する効果を有するエレベータの乗場ドア離脱防止装置を提供することにその目的がある。   The present invention has been made in order to solve the above-described problems of the prior art, and provides an elevator landing door separation prevention device that has a large separation prevention effect or a fundamental suppression effect on separation even at low cost. The purpose is to provide.

本発明のエレベータの乗場ドア離脱防止装置は、乗場ドアロック装置の取付板、連結板及びハンガープレートに加え、連結板の折り曲げを防止する離脱防止手段をさらに含み、乗場ドアに加えられた衝撃によって連結板が折り曲げられようとするときに、離脱防止手段が、連結板が折り曲がることを阻止して、乗場ドアが離脱されることを防止するように構成されている。   The elevator landing door detachment preventing device according to the present invention further includes a detachment preventing means for preventing the connecting plate from being bent in addition to the mounting plate, the connecting plate, and the hanger plate of the landing door locking device, and the impact applied to the landing door. When the connection plate is about to be bent, the separation preventing means is configured to prevent the connection plate from being bent and prevent the landing door from being detached.

本発明によれば、異常な衝撃や外力による乗場ドアの離脱を防止するために、ドアの強度を補強するために発生する費用を節減しつつ、乗場ドアへの異常な衝撃によりしばしば発生する乗場ドアの離脱に起因して、使用者または居住者が昇降路へ転落する事故を防止する効果を得ることができる。   According to the present invention, in order to prevent the landing door from being detached due to an abnormal impact or an external force, the landing often occurs due to an abnormal impact on the landing door while reducing the cost of reinforcing the strength of the door. It is possible to obtain an effect of preventing an accident in which a user or a occupant falls to the hoistway due to the separation of the door.
