DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seismic door capable of opening a door even if the door frame is deformed by an earthquake.

[0002]

2. Description of the Related Art A door is mounted on a door frame by a hinge so that the door can be freely opened and closed. When the door frame is deformed by an earthquake, the upper frame forming the door frame and the upper frame forming the door interfere with each other to form the door. You may not be able to open it.

[0003]

The problem that the door cannot be opened due to the interference between the upper frame and the upper frame is that the size of the dust between the upper frame and the upper frame is increased and the door frame is deformed by the earthquake. This can be prevented if the upper frame and the upper frame do not interfere with each other.

However, if the size of the dust is large between the upper frame and the upper frame, not only the appearance is poor, but also rainwater and dust easily enter between the upper frame and the upper frame. The durability of the sealing portion to be sealed may be reduced.

Therefore, an object of the present invention is to provide a seismic door capable of solving the above-mentioned problems.

[0006]

According to a first aspect of the present invention, there is provided a door in which a door is attached to a door frame by a hinge so as to be openable and closable. The part protrudes below the inner surface of the upper frame, and is provided so as to drop off by interfering with the upper outdoor part of the upper frame constituting the door, and the part of the attachment facing the upper outdoor part of the upper frame is a slope. When the upper outside of the upper frame is pressed against the slope, a force toward the outside is applied to the attachment, and the size of the dust between the lower end of the attachment and the upper end of the door is reduced. This is a seismic door characterized by having a large size between the inner surface and the upper end of the door. According to a second aspect of the present invention, in a door in which a door is attached to a door frame by a hinge so that the door can be opened and closed, an attachment is provided at a portion of the upper frame constituting the door frame near the outdoor side, and a lower end of the attachment is provided below the inner surface of the upper frame. A first posture that projects and is located on the outside of the door from the outside surface of the door, and a second posture that is pivoted to the outside of the door above the first posture, and is always free to rotate in the first posture. When the attachment is in the first position, the size of the dust between the lower end and the upper end of the door is reduced, and the size of the dust between the inner surface of the upper frame and the upper end of the door. This is an earthquake-resistant door characterized by having a larger size. According to a third aspect of the present invention, in a door in which a door is hingedly attached to a door frame, an attachment is provided on a portion of the upper frame constituting the door, which is closer to the outside of the door, such that an upper end thereof is higher than an upper end of the upper frame. It is provided so as to protrude and drop off by interfering with the inner surface of the upper frame, reduce the size of the dust between the upper end of this attachment and the inner surface of the upper frame, and reduce the distance between the inner surface of the upper frame and the upper end of the door. This is a seismic door with a larger size.

[0007]

[Operation] According to the first invention, the size of the dust between the inner surface of the upper frame and the attachment is small, the appearance is good, and rainwater and dust are hard to enter, and the door frame is deformed by the earthquake. At times, the attachment can drop off and the upper end of the door does not interfere with the inner surface of the upper frame, so that the door can be opened. According to the second invention, the size of the dust between the upper end portion of the door and the attachment is small and the appearance is good, and rainwater and dust are difficult to enter inside. Since the upper end does not interfere with the inner surface of the upper frame and the attachment can be rotated by the door, the door can be opened. According to the third invention, the size of the dust between the upper end of the door and the attachment is small, and the appearance is good.
