PROBLEM TO BE SOLVED: To provide a lifting/lowering door structure that can prevent a lifting/lowering door and a balance weight from falling suddenly.SOLUTION: A lifting/lowering door structure is characterized as follows: a weight of a lifting/lowering door 3 is set substantially the same as a total weight of all balance weights 4; also, the lifting/lowering door 3 and the balance weight 4 are hung so as to be lifted and lowered while matching in the upper and lower backward direction mutually through a fixed pulley 5 and a flexible suspension member 6; further, a first screw shaft 1 and a second screw shaft 2 are provided vertically and in parallel; a first nut member 11 is mounted to the lifting/lowering door 3 and the first nut member 11 is screwed to the screw shaft 1; a second nut member 12 responding from a lower position is screwed to the second screw shaft 2 to the balance weight 4 through a margin g in the up-and-down direction; and drive means 10 for rotating the first screw shaft 1 and the second screw shaft 2 is provided so that the first nut member 11 and the second nut member 12 may move in the upper and lower backward direction at the same speed.SELECTED DRAWING: Figure 1
【課題】昇降扉及びバランスウェイトの不意の落下を防止できる昇降扉構造を提供する。【解決手段】昇降扉３の重量と、全てのバランスウェイト４の合計重量とを、略同一に設定し、かつ、昇降扉３とバランスウェイト４とを、定滑車５と可撓性懸架部材６とを介して、相互に上下逆方向に釣合いながら昇降するように、吊持し、さらに、第１スクリューシャフト１と第２スクリューシャフト２を、鉛直状に、かつ、平行に設け、昇降扉３に第１ナット部材１１を取着すると共にスクリューシャフト１に第１ナット部材１１を螺合し、バランスウェイト４に対して、上下方向の余裕代ｇを介して下方位置から対応する第２ナット部材１２を第２スクリューシャフト２に螺合し、第１ナット部材１１と第２ナット部材１２が上下逆方向に同一速度で移動するように、第１スクリューシャフト１と第２スクリューシャフト２を回転させる駆動手段１０を具備している。【選択図】図１
