PROBLEM TO BE SOLVED: To provide a door device for a hatchway capable of reliably and easily executing both regulation of rotation in the further opening direction from an opening attitude of a door member and regulation of rotation in the closing direction, with a simple constitution.SOLUTION: A door device comprises a door frame 2 having a hatchway and incorporated into an upstairs floor, a door member 3 pivoted by the door frame 2 and opening/closing the hatchway and attitude setting means 5 provided between the door member 3 and the door frame 2 and setting an opening attitude of the door member 3. The attitude setting means 5 comprises a setting member 8 having one end connected to one of the door member 3 and the door frame 2 and having an engaging part 7 on the other end and a locking part provided in the other of the door member 3 and the door frame 2 and locking the engaging part 7 of the setting member 8. The engaging part 7 of the setting member 8 is provided with a first engaging part 7a for regulating rotation in the direction for further opening the door member 3 from the opening attitude and a second engaging part 7b for regulating rotation in the direction for closing the door member 3 from the opening attitude.SELECTED DRAWING: Figure 4
【課題】扉部材の開放姿勢からさらに開放する方向の回動の規制も、閉鎖する方向の回動の規制も、簡単な構成で確実かつ容易に行うことができる昇降口用扉装置を提供する。【解決手段】昇降口を有していて階上床に組み込まれる扉枠２と、この扉枠２に枢支されていて昇降口を開閉する扉部材３と、この扉部材３と扉枠２との間に設けられていて扉部材３の開放姿勢を設定する姿勢設定手段５とを備える。姿勢設定手段５は、扉部材３と扉枠２の一方に一端が連結されていて他端に係合部７を有する設定部材８と、扉部材３と扉枠２の他方に設けられていて設定部材８の係合部７を係止する係止部とを有する。設定部材８の係合部７には、扉部材３が開放姿勢からさらに開放する方向の回動を規制する第１係合部７ａと、扉部材３が開放姿勢から閉鎖する方向の回動を規制する第２係合部７ｂとを設ける。【選択図】図４
