EVACUATION DEVICE FOR TUNNEL
PROBLEM TO BE SOLVED: To make it possible to easily release a linkage relationship with an operation chain 15f whose timing matches that of a second door body 13 in the fully open position, when the second door body 13 is opened by movement of the operation chain 15f interlocking with an operation of an evacuation operation button 12, wherein a sliding type second door body 13 is provided in an evacuation port 3a provided in a partition body 3 that partitions the tunnel up and down.SOLUTION: An engaging member 17 provided on an operation chain 15f is engaged with a hook member 16 tiltably provided on a second door body 13 to move the second door body 13 to the door opening side, the hook member 16 is tilted so that the hook member 16 is released from the engagement with the engaging member 17 by bringing the hook member 16 into contact with a tilting member 18 at the timing that the second door body 13 is in the fully open position.SELECTED DRAWING: Figure 11
【課題】トンネルを上下に仕切る仕切り体３に設けた避難口３ａにスライド式の第二扉体１３を設け、該第二扉体１３を、避難用操作ボタン１２の操作に連動する作動チェーン１５ｆの移動によって開扉させるにあたり、第二扉体１３が全開姿勢になったことにタイミングを合わせた作動チェーン１５ｆとの連繋関係を簡単に解除できるようにする。【解決手段】第二扉体１３に傾動自在に設けたフック部材１６に、作動チェーン１５ｆに設けた係止部材１７を係止させて第二扉体１３を開扉側に移動させ、第二扉体１３が全開姿勢になることにタイミングを合わせてフック部材１６を傾動部材１８に当接移動させることでフック部材１６を係止部材１７に対する係止が解除されるように傾動させるようにした。【選択図】図１１
