PROBLEM TO BE SOLVED: To provide a door unlocking device with simple constitution that is applicable to an existing door easily at low cost through post-installation.SOLUTION: A door unlocking device 1 is provided for a door 3 installed in a free opening/closing state at an indoor opening part 2, and so configured that an operator manually operates to cause a latch bolt 4 of a key body keeping the door 3 in a closed state to retract into the door 3 from a latch bolt entry hole 5 provided on a door facing surface 3a of the opening part 2 so as to release the door 3 from being closed with the latch bolt 4. The door unlocking device 1 comprises: a push plate 8 which is provided to move forward and backward along a gap 7 formed between the door 3 and door facing surface 3a, and abuts on an inclined surface 4a of the latch bolt 4 projecting from the door 3 toward the latch bolt entry hole 5 to cause the latch bolt 4 to retract into the door 3; and a holding cover 10 which is provided on the door facing surface 3a of the opening part 2, guides and holds the push plate 8 in a forward/backward movable state along the door facing surface 3a.SELECTED DRAWING: Figure 1
【課題】既設のドアにも容易且つ安価に後付けで適用できる簡易な構成のドア開錠装置の提供。【解決手段】ドア開錠装置1は、室内の開口部2に開閉自在に設置されたドア3に設けられ、ドア3の閉状態を維持する錠本体のラッチボルト4を操作者の手動操作によって、開口部2のドア対向面3aに設けられたラッチボルト進入穴5からドア3の内方に退入させ、ラッチボルト4によるドア3の閉状態を解除するものである。ドア開錠装置1は、ドア3とドア対向面3aとの間に形成された隙間7に沿って進退自在に設けられ、且つ、ドア3からラッチボルト進入穴5の側に突出したラッチボルト4の傾斜面4aと当接することによりラッチボルト4をドア3の内方に退入させるプッシュプレート8と、開口部2のドア対向面3aに設けられ、プッシュプレート8をドア対向面3aに沿って進退自在に案内保持する保持カバー10と、を備える。【選択図】図1
