PURPOSE: To minimize damage when a door is broken by fixing a hinge component to the edge part of each panel by a fixing means consisting of a dove-tail- shaped projection, and by connecting both panels with a reinforcing bar. CONSTITUTION: Two parallel rails 10... are provided near a side part being extended in the longitudinal direction of each of panels 5 and 5 for composing a door. Then, at two opposite longitudinal edge parts of each rail, a fixing means consisting of a dove-tail-shaped projection 11... is provided. At one edge part, fixing to hinge components 18 and 19 for connection due to a reinforcing bar 21 is made. At the other, fixing to spacers 13... is carried out. Then, two rails 10 are connected each other by the spacer 13, and stiff filling plates 16 and 16 are filled into the region between the rails 10. When impact is given to the door, the panel 5 is separated from the part of the dove-tail-shaped projection 11, and only the panel 5 where the impact is given is damaged for preventing damage to the others. |
