<p>PROBLEM TO BE SOLVED: To prevent fingers from being caught by connecting the hanging side of a door to a door frame so as to be rotatable, and forming a recess on the center part of the groove wall of a door frame packing groove at a door end. SOLUTION: The upper edge of a door 1 at the hanging side and the lower edge thereof are rotatably coupled to an upper door frame 9A and a lower door frame 9B via pivotal hinges. In this case, the inner surface plate of the door 1 is structured so that the upper end 94a of the groove wall 93 of a packing groove on a vertical door frame 9d at a door end forms a recess 95 slightly larger than the thickness of fingers with the inner surface of the door 1 in a closed state. According to this construction, when the door 1 is suddenly closed, fingers, even if caught in a gap, are not subjected to a pressing force, thereby preventing the occurrence of an injury due to the fingers being caught.</p> |
