An auxiliary door 6 for opening and shutting the opening section 4 from the indoor side is provided. Usually, the auxiliary door 6 is shut in a state to mount the bar material 5. In the case of seeing a visitor, the auxiliary door 6 is opened, and the opening section 4 is opened with width C. The width C is sufficiently enough to receive mails, baggages, etc., and no outside visitor can enter. In the case of emergency evacuation, the auxiliary door 6 is opened to remove the bar material 5, and the opening section 4 is opened with width B. The width B is sufficient enough for the adult to easily go out.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an entrance door provided with both security and emergency escape measures.

[0002]

2. Description of the Related Art Conventionally, a door scope or a television camera is attached to a security door to open a front door after confirming a visitor in order to prevent a crime. Sometimes it is difficult to judge. Also, after checking with a door scope or a TV camera, visitors can be directly checked with the door chain attached,
If you do not remove the door chain, you will not be able to receive mail or luggage.

[0003] Therefore, it is difficult to prevent damages such as a door-opening or a television camera and a door chain equipped with a door-opening door being attacked by a visitor disguised as a courier service as soon as the door is opened.

[0004] On the other hand, in the case of an entrance door of an apartment or the like, the gap between the door body and the door frame is reduced in terms of airtightness and the like. , You may not be able to escape from the entrance.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of such problems of the prior art, and an object of the present invention is to provide a front door provided with both security measures and emergency escape measures. Make it an issue.

[0006]

In order to solve the above problems, an entrance door according to the present invention is provided with an opening in a door main body having a size that allows a person to enter and exit, and the width of the opening is set to be smaller in the entire vertical direction. A narrowing member for narrowing the width of the door body so that it cannot enter and exit is provided on the door body detachably from the indoor side, and an auxiliary door for opening and closing the opening from the indoor side is provided.

For security purposes, the auxiliary door is opened with the narrowing member attached to the door body, and the opening is opened in such a way that no person can enter or leave the entire vertical direction, thereby receiving mail or luggage. . Here, since the opening width of the opening is such that no people can enter or leave the entire vertical direction, outside visitors cannot enter the room.

At the time of emergency escape, by opening the auxiliary door with the narrowing member removed from the door body (or opening the auxiliary door and then removing the narrowing member), the opening has a width that allows a person to enter and exit. Since it is opened, it can escape from this opening.

[0009]

Embodiments of the present invention will be described below. FIG. 1 is a front view showing an entrance door of this embodiment, and FIG. 2 is a sectional view taken along line AA of FIG. In addition,
1 and 2 (a) show a state in which the auxiliary door is closed,
FIG. 2B shows a state where the auxiliary door is opened.

As shown in these figures, the door body 1 is
The door body 2 is attached to the door frame 2 by upper and lower hinges 3a and 3b, and an opening 4 is opened in the center of the door body 1. The opening 4 is formed in a vertically long rectangle with a predetermined width B (dimension that allows an adult to enter and exit).

The width of the opening 4 is such that a bar (narrowing member) 5 having a length corresponding to the vertical dimension of the opening 4 is provided on the door body 1.
(The width B → C). That is, for example, this bar 5
The length of the opening 4 is longer than the longitudinal dimension, and both ends in the length direction are bent at a right angle to become the periphery of the opening 4 as shown in FIG. 3 corresponding to a cross-sectional view taken along line BB of FIG. On the indoor surface of the door body 1,
It is configured to be attached with the wing nut 5a. here,
The door body 1 is provided with a through hole 10 through which the bar 5 penetrates. By doing so, the bar 5 can be easily removed from the indoor side by removing the wing nut 5a.

An auxiliary door 6 for opening and closing the opening 4 from the indoor side is attached to the door body 1 by upper and lower hinges 7a and 7b. The hinges 7a and 7b are connected to the door body 1
And the auxiliary door 6 is opened in a direction opposite to the door body 1.

Therefore, normally, the auxiliary door 6 is closed with the bar 5 attached, and when responding to a visitor, the auxiliary door 6 is opened so that no person can enter or leave the opening 4 in the entire vertical direction. Release at width C. With the width C, it is possible to easily receive mail and luggage, but since outside visitors cannot enter the room, security in crime prevention is enhanced.

When the door main body 1 cannot be opened due to a large earthquake or the like, the auxiliary door 6 is opened, the bar 5 is removed, and the opening 4 is opened with a width B that allows a person to enter and exit. Thereby, the person in the room can easily escape from the opening 4 to the outside.

In this embodiment, since the auxiliary door 6 is opened in the opposite direction to the door body 1, when the auxiliary door 6 is opened with the door body 1 locked, the auxiliary door 6 is opened from outside. The lock cannot be released by reaching out, and even if the auxiliary door 6 is opened in a state where the door body 1 is not locked, the door body 1 will not be opened together.

In the above-described embodiment, the width of the opening 4 is divided into two equal parts by the bar member 5. However, the narrowing member of the present invention is not limited to this, and for example, the member 4 is slid into the door main body 1. By providing an iron plate to enter and exit, the opening 4
May be variable between a width that allows a person to just enter and exit and a minimum width that is sufficient for delivery of mail or the like.

In the above embodiment, the opening 4 is provided at the center of the door main body 1. However, the opening 4 may be provided at a position off the center as long as it is easy to enter and exit during emergency escape. .

Further, in the above-described embodiment, a configuration is shown in which the auxiliary member 6 is opened and then the bar member 5 as the narrowing member is removed. However, the present invention is not limited to this. May be opened.

[0019]

As described above, according to the present invention,
An excellent entrance door provided with both crime prevention measures and emergency escape measures is provided, in which security measures are taken for visitors during normal times, and it is possible to go outside without opening the door body in an emergency.
