ESCAPE DOOR
To provide an escape door that can open/close a door properly and particularly eliminate the risk of sudden opening of vehicle doors even when air pressure in a roadway tunnel is applied to the door.SOLUTION: The escape door comprises: a first door (first door body 3) that opens/closes an opening connecting an escape connection hole and a roadway tunnel; and a second door (first slide door 6) that opens/closes an opening for people passing which is formed in the first door; lock means (Cremone handle H1, upper rod 11, lower rod 12, locking part L1, locking part L2) that keeps the first door body in a fully-closed posture; lock release restriction means (contacted part 15, stopper 16) that restricts the release of the lock means; and lock release allowance means (rod 160, operation mechanism, contact guide part 18) that cancels the lock release restriction by opening the second door in the fully-closed posture. When the opening for people passing is fully closed, the opening of the first door body is restricted, and when the opening for people passing is opened, the opening of the first door body is allowed.SELECTED DRAWING: Figure 1
【課題】車道トンネル内の風圧力が扉に作用している場合であっても、良好に扉の開放を可能とすると共に、特に車両用扉の急開放のリスクを無くす避難扉を提供する。【解決手段】避難連絡坑と車道トンネルを連通する開口部を開閉する第１扉（第１扉体３）と、第１扉に形成された人道用開口部を開閉する第２扉（第１スライド扉６）と、を備えた避難扉において、第１扉体の全閉姿勢を維持するロック手段（グレモンハンドルＨ１、上側ロッド１１、下側ロッド１２、係止部Ｌ１、係止部Ｌ２）と、ロック手段の解除を規制するロック解除規制手段（被当接部１５、ストッパー１６）と、全閉姿勢にある第２扉の開放によってロック解除規制を解除するロック解除許容手段（ロッド１６０、作動機構、当接ガイド部１８）と、前記人道用開口部の全閉時には第１扉体の開放が規制され、人道用開口部が開放された状態で第１扉体の開放が可能となっている。【選択図】図１
