EMERGENCY UNLOCKING DEVICE OF LOCKING DEVICE FOR DOOR
PROBLEM TO BE SOLVED: To provide a highly reliable emergency unlocking device of a locking device for a door that has an electric lock and a mechanical lock for emergency unlocking assembled in the door provided at a front opening part of a cabinet housing to be opened and closed, is increased in durability by making no unreasonable external force act on a driving part of the electric lock in a usual locking/unlocking operation by the electric lock, and can enter an unlocked state by an unlocking operation by only the mechanical lock independent of the driving part of the electric lock even if the electric lock cannot be powered owing to a power failure or flat battery in a locked state.SOLUTION: An emergency unlocking device of a locking device for a door comprises: a usual locking/unlocking mechanism having a structure bringing a door under opening/closing control by displacing a driving part displaced by a locking/unlocking operation of an electric lock 6 and a restriction member 32 associated with a contact state through an association tool 47; and an emergency unlocking mechanism which forcibly displaces the restriction member in an unlocking direction irrelevantly to the electric lock by a dead bolt 62 of a mechanical lock 7 to be placed in an unlocking operation when the electric lock becomes unusable in a locked state.SELECTED DRAWING: Figure 9
【課題】キャビネット筐体の前面開口部に開閉可能に設ける扉に、電気錠と非常解錠用の機械錠が組み込まれ、電気錠による通常の施錠・解錠操作時に該電気錠の駆動部に無理な外力を作用させないことで耐久性を高め、施錠状態で停電や電池切れの際に電気錠に通電できなくなった際にも、電気錠の駆動部から独立した機械錠のみの解錠操作で解錠状態にすることが可能な信頼性の高い扉の施錠装置における非常解錠装置を提供する。【解決手段】電気錠６の施錠・解錠操作によって変位する駆動部と連係具４７を介して接触状態で連係した規制部材３２を変位させ、扉を開閉制御する構造の通常施錠・解錠機構と、電気錠が施錠状態で使用不能となったとき、解錠操作する機械錠７のデッドボルト６２によって電気錠とは無関係に、規制部材を解錠方向へ強制的に変位させる非常解錠機構とを備えてなる。【選択図】 図９
