PROBLEM TO BE SOLVED: To provide a split door structure that reduces variation in a drive load at the time of lifting/lowering a door to enable smooth lifting/lowering action by using small driving torque.SOLUTION: A split door structure comprises: a pair of upper and lower pulleys 7 attached to each of right and left frame bodies 2; a first cable 8 wound around the pair of upper and lower pulleys 7; a first door body 3 that is fixed to the first cable 8 and is freely lifted/lowered along a first guide member 10 by rotation of the pulleys 7; a second door body 4 that is disposed so as to overlap with the first door body 3 and is freely lifted/lowered along a second guide member 11; a second cable 9 that has one end fixed on the frame body 2 and the other end fixed on the first door body 3; a sheave 14 that is supported by the second cable 9 and is fixed on the second door body 4; and a drive unit 16 that drives at least one of the pair of upper and lower pulleys 7.SELECTED DRAWING: Figure 4
【課題】扉昇降時の駆動負荷の変動を低減し、小さな駆動トルクで、円滑な昇降動作を可能とする分割扉構造を提供する。【解決手段】左右の枠体２夫々に取り付けられた上下一対のプーリ７と、前記上下一対のプーリ７に巻回された第１索条８と、前記第１索条８に固定され、前記プーリ７の回転により第１案内部材１０に沿って昇降自在な第１扉体３と、前記第１扉体３に重畳するように配置され第２案内部材１１に沿って昇降自在な第２扉体４と、一端が前記枠体２に固定され他端が前記第１扉体３に固定された第２索条９と、前記第２索条９で支持され前記第２扉体４に固定された滑車１４と、前記上下一対のプーリ７の少なくとも一方を駆動する駆動部１６と、を備えている。【選択図】図４
