FIRE DOOR ESCAPE MECHANISM AND CONVEYOR LINE WITH THE ESCAPE MECHANISM
To provide a fire door escape mechanism that can automatically retreat a device or the like that must be placed in a movement space of a fire door from the movement space to secure a space for the fire door to operate even if power or the like is cut off in an emergency.SOLUTION: A fire door escape mechanism 1 for retreating an installation member 3 arranged inside and outside a movement space S of a fire door 2 includes: an actuator 10 that allows the installation member 3 to move forward and backward between a position P1 on the movement space S and a retreat position; electrical retreat means 20 that drives the actuator of the installation member 3 when the fire door 2 operates, and is provided with a power supply line and an electric signal line for moving the installation member 3 from the position P1 on the movement space S to the retreat position; and mechanical retreat means 40 that automatically and non-electrically moves the installation member 3 from the position P1 on the movement space S to the retreat position, when the power supply line and/or the electric signal line of the electrical retreat means 20 is cut off during the operation of the fire door 2.SELECTED DRAWING: Figure 1
【課題】防火戸の移動空間に配置せざるを得ない装置等を、非常時に電力などが寸断された場合であっても、移動空間から自動で退避させ、防火戸が作動するための空間を確保することができる防火戸エスケープ機構を提供する。【解決手段】防火戸２の移動空間Ｓの内外に亘って配置される架設部材３を退避させる防火戸エスケープ機構１であって、架設部材３を移動空間Ｓ上の位置Ｐ１と退避位置の間で進退移動可能とするアクチュエータ１０と、防火戸２の作動時に架設部材３のアクチュエータを駆動させ、架設部材３を移動空間Ｓ上の位置Ｐ１から退避位置へ移動させるための動力供給ライン並びに電気信号ラインを備えた電気的退避手段２０と、防火戸２の作動時において電気的退避手段２０の動力供給ライン及び／または電気信号ラインが寸断された際に、自動かつ非電気的に架設部材３を移動空間Ｓ上の位置Ｐ１から退避位置へ移動させる機械的退避手段４０とを併設する。【選択図】図１
