Title:
DOOR STRUCTURE FOR PREVENTING CONFINEMENT IN ROOM AND DOOR MODIFYING MEMBER FOR THE DOOR STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2006/046594
Kind Code:
A1
Abstract:
A door structure capable of preventing inhabitants from being confined in a room in a large earthquake and a door modifying member for the door structure. In the door structure, an upper wall (3) tilting upward in a door opening direction (X) relative to a horizontal direction is formed at the upper end of a door body (1), and a tilted surface (12) is also formed on a door upper frame (11) correspondingly to the upper wall. Also, rotating members such as rollers in contact with a door lower frame are installed at the lower wall of the door body (1). Accordingly, when a door frame (10) is deformed by the earthquake, a force in the door opening direction (X) acts on the door body (1) since the door frame (10) presses the upper wall (3) of the door body (1). The rotating members at the lower wall facilitates the door opening operation.
