DOOR CLOSING RESTRICTION DEVICE
To provide a door closing restriction device in which a lock engaging member is hard to be an obstacle to passage when a worker passes through an opening.SOLUTION: A door closing restriction device 100 is configured such that one of a door frame 1 and a door body 2 is treated as an attachment object T to which a lock engaging member 3 is attached; the other of the door frame 1 and the door body 2 is treated as a non-object N; the direction perpendicular to an attaching surface Ta of the attachment object T is defined as a first direction; the direction that extends along the attaching surface Ta and concurrently that intersects the boundary between the door body 2 and the door frame 1 in the closed position is defined as a second direction Y; the lock engaging member 3 is slidably attached to the attachment object T by a sliding mechanism 4; and the lock engaging member 3, when sliding in the second direction Y, changes between a protruding posture in which at least a part of an insertion hole 31 of the lock engaging member 3 does not overlap with the attaching surface Ta when viewed in the first direction along the first direction, and a retracted posture in which the lock engaging member 3 entirely overlaps with the attachment object T when viewed in the first direction.SELECTED DRAWING: Figure 3
【課題】作業者が開口部を通行する際に、錠係止部材が通行の妨げとなり難い扉閉塞制限装置を提供する。【解決手段】扉閉塞制限装置１００において、扉枠１及び扉体２のいずれか一方を錠係止部材３が取り付けられる取付対象物Ｔとし、扉枠１及び扉体２のいずれか他方を非対象物Ｎとし、取付対象物Ｔの取付面Ｔａに直交する方向を第１方向とし、取付面Ｔａに沿う方向であって閉姿勢の扉体２と扉枠１との境界に交差する方向を第２方向Ｙとして、錠係止部材３は、摺動機構４により、取付対象物Ｔに対して摺動可能に取り付けられ、錠係止部材３は、第２方向Ｙに沿って摺動することにより、第１方向に沿う第１方向視で錠係止部材３の挿通孔部３１の少なくとも一部が取付面Ｔａと重複しない状態となる突出姿勢と、第１方向視で錠係止部材３の全体が取付対象物Ｔと重複する状態となる引退姿勢とに変化する。【選択図】図３
