Further, a handle 11 is attached to a position slightly below the substantially central position of the left side portion of the frame portion 7 in FIG. 1, and a key mechanism 13 is attached on the handle 11.

As shown in FIG. 3, the handle 11 is provided with grip portions 11a and 11b inside and outside the entrance door 5, and by grasping and rotating the grip portions 11a and 11b, the locking projection 15 is formed. It is retracted from the side of the frame body 1, thereby enabling the entrance door 5 to be opened. Further, when the front door 5 is closed, the locking projection 15 is automatically projected and engaged with the frame 1 side by the elastic force of the elastic member (not shown), thereby closing the front door 5. I try to keep the condition. Further, the key mechanism 13 is configured to rotate the knob 13a so as to insert and remove the locking projection 17 shown in FIG.
It is brought into a locked state (inhibiting the opening of the entrance door 5) by projecting it to the side and engaging it. As shown in FIG. 2, by inserting a key 21 (not shown) from the outer key insertion portion 19, for example, the key mechanism 1 described above.
The locked state can be released by 3.

Further, as shown in FIG. 1, a hydraulic mechanism 23 is attached to the upper end of the entrance door 5 on the right side in FIG. That is, when the entrance door 5 is left open, the entrance door 5 is automatically closed by the elastic force of the elastic member (not shown).
For example, when the entrance door 5 is left open, it is possible to prevent the entrance door 5 from being suddenly closed due to the elastic force of the elastic member, and to close the entrance door 5 at a moderate speed. It works as it can.

An emergency door 25 is attached to the entrance door 5 having the above structure. This emergency door 25
As shown in FIGS. 3 and 4, for example, it is formed in a box shape by a thin plate made of aluminum, and the inside thereof is hollow. As shown in FIG. 4, the emergency door 25 is provided with hinges 27 and 29 on the upper and lower sides, and is rotatably attached to the frame portion 7 of the entrance door 5 via the hinges 27 and 29. It is open (one-sided method). A key mechanism 28 is attached to the right side of the emergency door 25 in FIG. The key mechanism 28, as shown in FIG.
9 is provided, and by rotating the knob portion 31,
The locking protrusions 29 are inserted into and removed from the frame portion 7 side of the entrance door 5.

The emergency door 25 is normally closed and locked by the key mechanism 28. Then, for example, when an earthquake occurs and the entrance door 5 side cannot be opened, the lock by the key mechanism 28 is released inside to open the emergency door 25 and escape to the outside.

The details of the construction of the emergency door 25 will be described in detail. First, in a portion located between the emergency door 25 and the frame portion 7 of the entrance door 5 and located outside the entrance door 5,
As shown in FIG. 3, a sealed rubber body 33 is inserted.
The hermetically sealed rubber body 33 has a hollow shape and is inserted so as to fill an annular gap between the emergency door 25 and the frame portion 7. The hermetically sealed rubber body 33 ensures airtightness and liquid tightness, and also exhibits soundproofing and insectproof (insect invasion) functions.

In addition, between the emergency door 25 and the frame portion 7 of the entrance door 5 and also in a portion located inside the entrance door 5,
The sealed rubber body 35 is inserted. This sealed rubber body 35
Is also hollow, and is inserted so as to fill the annular gap between the emergency door 25 and the frame 7. The hermetically sealed rubber body 33 ensures airtightness and liquid tightness, and also exhibits soundproofing and insectproof (insect invasion) functions.
That is, the hermetically sealed rubber body 33 and the hermetically sealed rubber body 35, which have already been described, doubly ensure air-tightness and liquid-tightness, and exhibit soundproofing and insect-proof (insect invasion) functions.

The left side of the sealed rubber body 35 in FIG. 3 is attached to the frame 7 side of the entrance door 5, but the other three sides are attached to the emergency door 25 side. There is. This is to make the opening operation of the emergency door 25 smoother while maintaining the airtight, liquid-tight, soundproof, and insectproof (prevention of insect invasion) functions. That is, FIG.
On the right side in the middle, if the sealing rubber body 35 is attached to the frame portion 7 side, the opening operation of the emergency door 5 is impaired. On the other hand, since the sealing rubber body 35 is attached to the emergency door 25 side, such a situation does not occur and the emergency door 25 can be easily opened. Further, the sealing rubber body 35 in the portion located on the left side in FIG. 3 is appropriately deformed and does not impair the opening operation of the emergency door 25.

Further, as shown in FIG. 3, the upper left corner portion 25a of the emergency door 25 in the drawing has a shape that is partially cut. This is to prevent the corners 25a of the emergency door 25 from being caught on the side of the sealing rubber body 33 and impairing the smooth opening operation when the emergency door 25 is opened.

The emergency door 25 itself has the above-mentioned structure. However, when the emergency door 25 is attached to the front door 5, it is necessary that the emergency door 25 cannot be seen from the outside. This is because of an aesthetic problem as the entrance door 5, and at the same time, there is a concern that an intruder may intrude. Therefore, in this embodiment, as shown in FIGS.
So that it covers the outside of the boundary between the frame 7 of the entrance door 5 and
A so-called "mall" 37 is attached. Since the outside of the boundary between the emergency door 25 and the frame portion 7 of the entrance door 5 is shielded by the molding 37, the presence of the emergency door 25 cannot be recognized from the outside. That is,
From the outside, it can only be recognized as a front door 5. Reference numeral 41 in FIGS. 1 and 2 is a peephole, and reference numeral 43 in FIGS. 3 and 4 is the frame 1 and the entrance door 5.
It is a sealed rubber body inserted between and.

According to this embodiment, the following effects can be obtained. First, in the event of an emergency such as an earthquake, if the entrance door 5 cannot be opened, the lock by the key mechanism 31 can be released, and the emergency door 25 can be opened to escape to the outside. , It has become possible to escape to the outside more easily than the conventional escape from a balcony or the like. In particular, in the case of escape through the entrance, as a matter of course, the escape route is secured (since the passage in normal times functions as the escape route as it is), so it is much safer than the escape through the veranda etc. And it becomes a sure criticism. FIG. 5 shows how the entrance door 5 is opened and closed and the emergency door 25 is opened and closed. Further, since the presence of the emergency door 25 cannot be recognized from the outside by the mall 37, the entrance door 25
As a result, the aesthetic appearance is not impaired, and the intruder does not unnecessarily recognize the existence of the emergency door 25 and does not induce the intrusion. Moreover, the hinge 2 provided between the emergency door 25 and the entrance door 5 side
Since it is attached so as to be rotatable inward through 7 and 29, and has a shape in which a part of the corner located on the hinge 27, 29 side and outside is removed, the emergency door 2
It is possible to prevent a structure on the entrance door 5 side from being caught when the 5 is rotated to be opened, and a smooth opening operation of the emergency door 2 can be provided.
Further, since the sealing rubber bodies 33 and 35 are inserted inside and outside the emergency door 25 and the entrance door 5, respectively, the sealing rubber bodies 33 and 35 enable airtightness, liquid-tightness and soundproofing.
It is possible to obtain an insect repellent (prevention of insect invasion) effect. Further, in the sealed rubber body 37 inserted inside, the hinge 27,
Since the side located on the 29 side was attached to the entrance door 5 side and the other portions were attached to the emergency door 25 side, while maintaining airtightness, liquid tightness, soundproofing, insect repellent (insect invasion) effect, The opening / closing operation of the emergency door 25 can be facilitated.

The present invention is not limited to the above-mentioned one embodiment. For example, the front door 5 of the emergency door 25
The mounting structure for is not limited to the one-sided opening method as in the above-described one embodiment, and various modifications such as a one-sided opening method from the reverse direction, a one-sided opening method in the vertical direction, a double-sided opening method, and a shutter method can be considered. Also, as for the configuration of the key mechanism 31, various known key mechanisms can be applied. Further, a handle may be provided at a predetermined position inside the emergency door. The size and shape of the emergency door are not particularly limited, and the material of each part is also the same, and may be made of wood, steel, or stainless steel. Further, in the above-described one embodiment, the example in which the invention is applied to the entrance door is shown, but it is needless to say that the invention can be similarly applied to the door inside the building.

[0020]

As described in detail above, according to the door device of the present invention, first, in the event of an emergency such as an earthquake, if the door cannot be opened, the lock by the key mechanism is released. The emergency door can now be opened to easily escape to the outside. In particular, in the case of applying to an entrance door, in the case of escape through the entrance, it is natural that an escape route is secured (since the passage in normal times functions as an escape route), for example, It is possible to increase the safety compared to the escape through the balcony. Further, since the presence of the emergency door is configured so that it cannot be recognized from the outside, for example, when it is applied to an entrance door, the aesthetic appearance of the entrance door will not be impaired at all, and it will be very difficult for an intruder to see. There is no need to unnecessarily recognize the existence of a service door and trigger its intrusion. In addition, the emergency door is rotatably mounted inwardly via a hinge provided between the emergency door and the hinge, and the corners on the outside of the hinge are partially removed. And if
When rotating the emergency door to open it, it is possible to reliably prevent the structure on the door side from being caught, and it is possible to provide a smooth opening of the emergency door.
In addition, when a sealing rubber body is inserted between the emergency door and the outside of the door, respectively, the sealing rubber body provides air-tightness, liquid-tightness, soundproofing, and insect-proof (prevention of insect invasion) effects. You can get Also, in the sealed rubber body inserted inside, attach the side located on the hinge side to the door side,
If other parts are attached to the emergency door side,
The opening / closing operation of the emergency door can be facilitated while maintaining the effects of airtightness, liquid-tightness, soundproofing, and insectproof (prevention of insects from entering).
