ENTRANCE DOOR DEVICE
To provide an entrance door device capable of achieving both crime prevention and maintainability while maintaining hanging workability.SOLUTION: The hinge includes a temporary hanging member for temporarily hanging a door body by receiving a lower end of a shaft member passed through an upper shaft hole of a door body side hinge member. The temporary hanging member includes a cylindrical wall portion projecting upward, a notch portion provided in a part of the cylindrical wall portion and capable of laterally inserting the lower end of the shaft member into an inner side of the cylindrical wall portion, and a longitudinal groove provided in an inner surface of the cylindrical wall portion along the longitudinal direction and allowing the shaft member to be inserted into and removed from a lower shaft hole when a first protrusion is engaged. A width of the longitudinal groove along a circumferential direction of the cylindrical wall portion is formed to be larger than the width of the first protrusion along a circumferential direction of the shaft member so that the first protrusion can be engaged within a predetermined angular range along the opening/closing direction of the door body.SELECTED DRAWING: Figure 8
【課題】吊り込み作業性を維持しつつ、防犯性及びメンテナンス性を両立させることができる玄関ドア装置を提供すること。【解決手段】丁番は、ドア本体側丁番部材の上軸孔に貫通された軸部材の下端を受け入れてドア本体を仮吊り込みする仮吊り込み部材を備える。仮吊り込み部材は、上方に向けて突出する円筒壁部と、円筒壁部の一部に設けられ、軸部材の下端を円筒壁部の内側に横方向から挿入可能な切り欠き部と、円筒壁部の内面に縦方向に沿って設けられ、第１の突起が係合した場合に、下軸孔に対する軸部材の挿入及び抜去を許容する縦溝と、を備える。円筒壁部の周方向に沿う縦溝の幅は、ドア本体の開閉方向に沿う所定の角度範囲で第１の突起を係合可能となるように、軸部材の周方向に沿う第１の突起の幅よりも大きく形成される。【選択図】図８
