Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seismic resistant door which can be opened even if the door frame is deformed by an earthquake.

[0002]

2. Description of the Related Art A door is a door frame attached to the door frame so that the door can be opened and closed by a hinge. When the door frame is deformed by an earthquake, the upper frame forming the door frame and the upper frame or the lower frame forming the door come into strong contact with each other. And sometimes the door cannot be opened.

For example, as shown in FIG. 1 (a), the vertical frame b of the door and the vertical frame c of the door tip of the door frame a are tilted in the left-right direction, and the door frame a is
When it is deformed into a substantially parallelogram shape as shown in (b), the vertical frame b and the door d are slanted, and the upper frame e of the door d is in strong contact with the upper frame f of the door frame a. Sometimes it can't be released.

[0004]

Since the door d cannot be opened due to the interference between the upper frame f and the upper frame e, the size of the dust between the upper frame f and the upper frame e is increased to make the door frame a. Even if is deformed by an earthquake, it can be prevented by preventing the upper frame f and the upper frame e from interfering with each other.

However, if the size of dust is large between the upper frame f and the upper frame e, not only does it look bad, but rainwater and dust easily enter between the upper frame and the upper frame e, and the upper frame f and the upper frame e. The durability of the sealing material that seals between the gap and the gap may decrease.

Therefore, an object of the present invention is to provide a seismic resistant door that can solve the above-mentioned problems.
