FIRE SHUTTER
To satisfactorily close a side part of a rail when an opening is fully closed.SOLUTION: A rail 4 is laid on a floor surface FL so as to be substantially perpendicular to an opening that is to be closed by a shutter, a recessed section opening downward and corresponding to the rail 4 is formed in a seat plate 3 of a shutter curtain, and a blocking member 5 is provided so as to be able to rotate and is positioned at the side edge of the recessed section. When the seat plate 3 is positioned above the rail, the blocking member 5 is urged to maintain a first posture, and when the opening is fully closed, the rail 4 is positioned in the recessed section and the blocking member 5 is in a second posture in contact with a side surface 41 of the rail 4.SELECTED DRAWING: Figure 3
【課題】開口部全閉時にレールの側方部位を良好に塞ぐ。【解決手段】床面ＦＬには、シャッターによって閉鎖される開口に略直交するようにレール４が敷設されており、シャッターカーテンの座板３には、レール４に対応して下方に開口した凹部が形成されており、凹部の側縁に位置して塞ぎ材５が回動可能に設けてある。座板３がレール上方に位置する時には、塞ぎ材５が第１の姿勢を維持するように付勢されており、開口部全閉時には、レール４が凹部内に位置して、塞ぎ材５がレール４の側面４１に当接した第２の姿勢となる。【選択図】図３
