SMOKE BLOCKING STRUCTURE AND AUTO DOOR HAVING THE SAME
PROBLEM TO BE SOLVED: To provide an auto door which while keeping a plurality of door materials in fast up/down movement exhibits smoke blocking performance with the door materials closed.SOLUTION: A smoke blocking structure of an auto door has: a slide body which fit door materials of the auto door to a door rail for up/down movement; a support member which has one end coupled to the slide body to move in a front/rear direction and the other end fixed to side faces of the door materials, and is provided with a projection part on a rear face; and a cam which is fitted to a rear side of the door rail so as to push the projection part out when the support member passes a predetermined position, the projection part being pushed with the cam when the auto door is closed to press the door materials to close a gap formed with a frame material of the auto door.SELECTED DRAWING: Figure 1
【課題】複数の戸材が上下に高速移動するように維持しつつ、戸材を閉じたときには高い遮煙性能を発揮するオートドアを提供する。【解決手段】オートドアの遮煙構造は、オートドアの戸材を上下方向に移動させるためのドアレールに嵌合させる摺動体と、一端は前後方向に移動可能に前記摺動体と連結され、他端は前記戸材の側面に固定され、後面に突出部が設けられた支持部材と、前記支持部材が所定の位置を通過するときに前記突出部を前方に押し出すように前記ドアレールの後側に取り付けられたカムと、を有し、前記オートドアを閉じたときに、前記突出部が前記カムに押され、前記戸材が前記オートドアの枠材との隙間を塞ぐように押し付けられる、ことを特徴とする。【選択図】図１
