Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door for people such as houses and offices to enter and leave.

[0002]

2. Description of the Related Art In general houses, particularly in condominiums, apartments and office buildings having a reinforced concrete structure, steel doors or hard wooden doors are often used as doorways for security purposes.

[0003]

When a large vibration force is applied to a building due to the occurrence of a large earthquake or the like, the building is deformed due to the shear deformation and the compressive force from the upper part, which makes it difficult to open and close the door. In particular, the one-piece steel steel door and hard wooden door as described above cannot be easily opened and closed manually.
Moreover, in the event of an earthquake disaster, the doors of many houses and offices fall into such an inoperable state at the same time, so rescue work to open a huge number of doors is virtually impossible.

As a result, it takes time to evacuate and the damage is further increased when an indoor fire occurs. In addition, if you continue to live in the area after the earthquake, if the earthquake is large, you will not be able to repair the door due to lack of personnel, and you will need to use the door without repairing it. Not safe for crime prevention.

The object of the present invention is to eliminate the inconvenience of the prior art example, and even if the door cannot be opened / closed due to the deformation of the building in the event of an earthquake, an evacuation exit can be secured for quick emergency evacuation. It is to provide a door that can ensure security for crime prevention.

[0006]

In order to achieve the above-mentioned object, the present invention is smaller than the door body and can be locked from the inside so that the door body is not deformed by an external force such as an earthquake applied to the inside of the door body. The door is integrated, and the inner door has its lower end pivoted to the outdoor side of the door body, and the inner door has its side end pivoted to the indoor side of the door body and can be locked from the outdoor side. The point is that a lock is provided.

According to the first aspect of the present invention, even if the building is deformed due to an earthquake or the like and the door body cannot be opened or closed,
Since the external force due to the earthquake is not transmitted to the inner door provided on the inner side, the inner door can be opened and closed and used as an evacuation exit even in the event of an earthquake disaster. In addition, by locking the inner door to the door body during normal times, it is possible to ensure security for crime prevention, and since it can be used integrally with the door body, usability does not deteriorate.

According to the second aspect of the present invention, in addition to the above-mentioned action, the inner door is pivotally attached to the lower portion of the outdoor side of the door body, so that it is possible to kick it off from the indoor side with a foot during an emergency evacuation. Therefore, quick evacuation is possible.

According to the third aspect of the present invention, in addition to the above-mentioned action, the side end of the inner door is axially attached to the indoor side of the door body, and a lock that can be locked from the outdoor side is provided. Even if the door cannot be opened or closed, this inner door can be used independently, and the specifications are the same as those of the door body that was used up until then, which is convenient.

[0010]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a front view showing a first embodiment of a door of the present invention, FIG. 2 is a cross-sectional plan view of an essential part of the same, and in FIG. 1, 1 shows a door body made of steel, for example, as a member responsible for the strength of the door, The door body 1 has its side portion pivotally attached to the door frame by a hinge 2.

The inner door 3 is integrally incorporated inside the door body 1. The inner door 3 is smaller than the door body 1 and is about half the size in the illustrated example, and an opening 4 serving as an evacuation doorway is provided in a substantially lower half of the door body 1, and the opening 4 is always provided. The lower end of the inner door 3 was attached to the outside of the door body 1 by pivotally attaching the lower end of the inner door 3 with a hinge 5.

Then, locks 6 such as hooks that can be locked from the inside of the room are attached to the left and right side portions of the inner door 3, and locking pieces 7 with which the lock 6 is locked are attached to the door body 1 side. Although not shown, packing is provided between the inner door 3 and the door body 1 to ensure airtightness and watertightness.

As described above, the inner door 3 is integrally incorporated in the door body 1, and even if the building deforms due to shear deformation and compressive force of the upper part due to an earthquake or the like, the door body 1 is distorted by the force from the building. The inner door 3 is not subject to forced deformation of the door body 1.

Therefore, at the time of an earthquake, even if the door body 1 is distorted and cannot be opened or closed due to the deformation of the building, the seismic force is not transmitted to the inner door 3. Therefore, the lock 6 of the inner door 3 is locked. 7
Then, as shown in FIG. 3, when the hinge 5 at the lower end is used as an axis and is pushed open to the outside of the room, the opening 4 is opened and escapes to the outside of the room.

When an emergency evacuation is required due to a fire in the room, the lower end of the inner door 3 is attached to the outside of the door body 1 so that it can be kicked outside. Yes, you can escape quickly.

In normal times, the inner door 3 is integrally incorporated in the door body 1, and the inner door 3 and the door body 1 can be used as a unitary door, which does not deteriorate usability. ,
Since it is locked to the door body 1 by the lock 6, security for crime prevention can be ensured.

4 and 5 show a second embodiment, in which the inner door 3 incorporated inside the door body 1 is formed in a shape similar to the door body 1 and slightly smaller than this, and the side portions are hinged 5. A suitable number of locks 8 can be attached to the inside of the door main body 1 by being axially attached to the opening edge of the opening 4 formed in the door main body 1 and locked from the inside to the other side (three in the illustrated example). I installed it.

A keyhole 9 is provided on the outside of the door body 1 so that the lock 8 can be locked and unlocked from the outside. Reference numeral 10 in the drawing denotes a packing interposed between the inner door 3 and the door body 1.

In the case of the second embodiment as well, as in the first embodiment, the inner door 3 is not forcibly deformed even if the door body 1 is distorted due to the deformation of the building when an earthquake occurs.
When the door is removed, the inner door 3 opens to the inside of the room, and thus escapes from the opening 4 to the outside of the room.

When the room with the door is used even after the disaster, the inner door 3 can be opened and closed independently and can be locked from the outside. Therefore, even if the door body 1 cannot be used, the inner door 3 can be used. Has a door function by itself, and can be used as a normal door that opens and closes an entrance.

In the above-described embodiment, the lock that can be locked from the indoor side is manually opened and closed, but the invention is not limited to this. For example, a lock that can be mechanically and automatically opened even when an earthquake occurs. It can also be used.
