SUMMARY OF THE INVENTION According to the present invention, there is provided a door frame in which an upper frame, a lower frame, and left and right vertical frames are squarely framed, and a door is a hinge, and an outer surface of the door room is closed with the door closed. The outside surface, the pivot is mounted so as to be closer to the room than the outside of the vertical frame, and the center of rotation of the flag hinge is closer to the room than the outer surface of the upper frame, the outside surface of the vertical frame, and more than the outside surface of the door. The interior of the upper frame is almost stair-shaped, with the interior side lower, the interior vertical side, and the exterior side horizontal side, and the interior side is low and the outdoor side is high, with the door closed. When the door is turned toward the outside of the room by about 90 degrees, the door is made to face the side surface on the outside side, and the vertical dimension between the top surface of the door and the side surface on the outside side of the upper frame is flagged. The door is characterized in that it is larger than the hinge fitting margin.

[0008]

According to the present invention, when the door is turned almost 90 degrees toward the outside of the room, the door faces the lateral side of the upper frame closer to the outside of the room, and the door is raised upward beyond the fitting margin of the flag hinge. Can be moved to
The door can be attached or removed.

With this, the size of the upper surface of the door and the inner surface of the upper frame when the door is closed is small, and the center of rotation of the flag hinge does not protrude outside the room from the upper frame. Even when the door cannot be turned toward the outside of the room by more than 90 degrees due to a gap or the like, the door can be attached or removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS.
The door frame 23 is formed by abutting and connecting the 0 and the lower frame 21 to the left and right vertical frames 22. The upper frame 20, the lower frame 21, the vertical frame 22
Are the indoor side members 20a, 21a, 22a and the outdoor side member 20
b, 21b, and 22b are heat-insulated members connected via heat-insulating materials 20c, 21c, and 22c, and the door frame 23 is an insulated door frame.

The door 24 is an insulating door. Specifically, the U-shaped channel member 25 is formed into a square frame, and the upper frame member 26, the lower frame member 27, and the indoor-side vertical frame member 2 made of a synthetic resin are surrounded therearound.
8. Attach the outdoor side vertical frame member 29, attach the indoor side surface plate 30 and the outdoor side surface plate 31 over each frame member, and fill the inside with a heat insulating material 32 such as urethane foam. Is installed.

One blade 41 of the flag hinge 40 is fixed to the inner surface of the outdoor member 22b of the one vertical frame 22, and the other blade 42 is fixed to the left vertical member 33 (one vertical surface) of the door 24. I have. A longitudinal axis 43 is provided at one end of one of the blades 41 projecting outside the door 24 from the door 24.
3 is fitted in a shaft hole 44 at one end of the other blade 42 protruding outside the door 24 from the door 24.

Thus, the rotation center 4 of the flag hinge 40 is
0a is closer to the outdoor side than the outdoor side surface 24a of the door 24 in a state of being completely closed closer to the indoor side than the outdoor side surface 20d of the upper frame 20 and the outdoor side surface 22d of the vertical frame 22.

An inner surface 20e of the upper frame 20 (outdoor member 20b) has an indoor side surface 50 facing the upper surface 24b of the door 24 with the door 24 closed, and an outdoor end of the indoor side surface 50. An intermediate vertical surface 51 facing upward and an outdoor side surface 52 facing the outdoor side from the upper end of the intermediate vertical surface 51,

As shown by an imaginary line in FIG. 2, the upper surface 2 of the door 24 is separated from the indoor side surface 50 and faces the outdoor side surface 52.
The vertical dimension between the upper frame 4b and the upper frame 20 is larger than the length (fitting allowance) of the longitudinal axis 43 of the flag hinge 40.

As described above, the door 24 can be moved upward beyond the length (fitting allowance) of the longitudinal axis 43, so that the door 24 can be attached or detached.

Therefore, as shown by the imaginary line in FIG. 3, even when the building outer wall 60 protrudes outside the door frame 23 from the door frame 23 to the outside and the door 24 cannot be turned more than 90 degrees toward the outside, the door may be closed. 24 can be attached or detached.

In the above embodiment, the insulated door has been described, but the same applies to a door using a normal aluminum frame material.

[0020]

According to the present invention, when the door is turned substantially 90 degrees toward the outside of the room, the door faces the side surface of the upper frame closer to the outside of the room, and the door is moved beyond the fitting margin of the flag hinge. Because it can move upward, the door can be attached or removed.

Accordingly, the size of the upper surface of the door and the inner surface of the upper frame when the door is closed is small, and the center of rotation of the flag hinge does not protrude outside the room from the upper frame. Even when the door cannot be turned toward the outside of the room by more than 90 degrees due to a gap or the like, the door can be attached or removed.
