摘要： PURPOSE:To enable diversification and differentiation of a door design by a method wherein upper and lower frameworks are mounted to the style of a building door to form a 3-way framework, a door panel is inserted and mounted in the in-plane groove of the 3-way framework, and the style is mounted to an open part. CONSTITUTION:An upper framework 12 is mounted to the upper part of a style 11 of a building door and a lower framework 13 to the lower part thereof to form a 3-way framework 1. A door panel 2A is inserted in in-place grooves 12a and 13a to slide it, and inserted and mounted in the plane of the 3-way frame-work 1. Upper and lower styles 14 are securely arranged to connection parts 12b and 13b formed at the upper and lower frameworks 12 and 13. Thus, by removing the style 14, exchange of a door panel is practicable, and the design of a door can be freely represented only by assembling together the 3-way frame-work and the door panel.

摘要： PROBLEM TO BE SOLVED: To minimize a displacement of a door frame and prevent the door from disabling from opening or closing even when a displacement has arisen in a building, by housing the door frame of a metallic door into the external frame and interposing a displacement- absorption structure with springs between the external frame and the door frame. SOLUTION: A door frame 2 of a metallic door 4 is housed in an external frame 7 and a displacement-absorption structure 8 is interposed with springs between the external frame 7 and the door frame 2. In the displacement-absorption structure 8, the opened face 7a of the external frame 7 is turned to the door frame 2 side, and projections 10 are formed outward at the door frame 2 to freely slide into the external frame 7. A bolt 12 except a head 12a is welded to the outside of the external frame 7 and arranged to pierce the external frame 7 and inserted in the through hole 11 of the door 2 to freely slide therein at the front end thereof. And further, a coil spring 9 is wound on the bolt 12. The displacement-absorbing structures 8 having such a constitution are arranged at two upper and lower positions on the vertical frame and at two right and left positions on the upper frame. In this way, even when a displacement has arisen in an earthquake, an external force is absorbed by the external frame 7 so as to smoothly open or close the door.

摘要： PROBLEM TO BE SOLVED: To easily and secuely prevent such a trouble of fittings that a door body is caught by a door frame and can not be opened even if a relative story displacement of a building has arisen at an earthquake and forming a relatively displaceable lap joint part as a unit to simplify the fitting works and increase the accuracy and the wide usability. SOLUTION: When metallic fittings like a steel door set 4 are arranged between self-standing mullions 5 erected in the relative stories of a building, the self-standing mullions 5 are vertically connected to each other by a relatively displaceable lap joint provided with coil springs 15a, 15b interposed therein. The relatively displaceable lap joint is surrounded at the periphery by a cylindrical cover in which the springs are contained. Further, this structure is constituted of a unit device 29 provided with welding parts with the self-standing mullions in the Job site.

摘要： PROBLEM TO BE SOLVED: To prevent the wear of an air-tight member, and to improve the safety by setting the distance from the center of the axis of a pivot hinge to a closely attached part to the air-tight member provided on a longitudinal frame to the prescribed value, and curving the surface of a hanging end part to the prescribed shape. SOLUTION: A hinge door is opened/closed around the axis of a pivot hinge provided above and below a hanging end part 2. The surface of the end part 2 is curved following the curve whose curvature is gradually reduced from the point B on the surface located on the line passing through the center O of the axis of the pivot hinge and parallel to the surface of the hinged door to the point A of a closely attached part to an air-tight member 5 so that a finger is not caught between the end part 2 and a longitudinal frame 6. The distance L1 from the center O to the point A is larger than the distance L2 from the center O to the point B. When the door is closed, the point B passes the part closer to the center O than the air-tight member 5 forming an arc with its center at the point O and the radius L2, and the point A forms an arc with its center at the point O and the radius L1, and is intersected with the outer circumference of the air-tight member 5, and the air-tight member 5 is closely attached to the end part 2 only in the closed condition of the door to prevent the wear.
