Freezing prevention device for door at elevator landing place

エレベータ乗場の戸の凍結防止装置

Abstract

【課題】エレベータ乗場の戸が屋外に面している場合、吹雪の際に乗場の戸の表面に雪が付着しそれが凍結して乗場の戸の開閉に支障を来たす恐れがあるので、乗場の戸の表面に雪が付着してもそれが凍結することを防止できるエレベータ乗場の戸の凍結防止装置を得る。 【解決手段】乗場出入口を開閉自在に覆い内部に空気流通路が形成された乗場の戸と、この乗場の戸の下端部と係合して乗場の戸を案内する敷居溝を有する敷居と、この敷居の下部に設けられた敷居受けと、この敷居受けに設けられ敷居を加熱するとともに上方に向かう加熱空気流を生成する加熱手段と、敷居受け及び敷居溝にそれぞれ設けられ加熱手段からの加熱空気流を乗場の戸の空気流通路に通風させる通風用の貫通孔とを備える。乗場の戸の上部に設けられ加熱空気流を外部へ放出する空気流出孔を備える。 【選択図】 図2
PROBLEM TO BE SOLVED: To provide a freezing prevention device for a door at an elevator landing place capable of preventing freezing of the door even if snow adheres to a surface of the door at the landing place, although there is a possibility that snow adheres to the surface of the door at the landing place and is frozen, thereby preventing the door at the landing place from being opened and closed, when a snowstorm comes in the case where the door at the elevator landing place faces the outdoors. SOLUTION: This freezing prevention device is provided with the door at the landing place covering a landing place doorway so as to open and close freely and forming an air stream passage inside it, a threshold having a threshold channel engaging with a lower end part of the door at the landing place to guide the door at the landing place, a threshold receiver provided in a lower part of the threshold, a heating means provided in the threshold receiver to heat the threshold and form a heated air stream going upward, and through holes for ventilation provided in the threshold receiver and the threshold channel, respectively, to conduct the heated air stream from the heating means into the air stream passage of the door at the landing place. An air flowing-out hole provided in an upper part of the door at the landing place to discharge the heated air stream to the outside is provided. COPYRIGHT: (C)2005,JPO&NCIPI
