The present invention relates to a device devised such that when it becomes impossible to open a door, an emergency door attached to the door can be opened to escape to the outside.

[0002]

2. Description of the Related Art For example, in an entrance of an apartment house such as reinforced concrete or steel frame, an entrance of an office or the like, or an entrance of a hotel guest room, an abnormal pressure acts on an entrance door due to an earthquake or the like, and a door frame is formed. In some cases, the opening and closing of the device may become impossible due to the deformation of the device. In such a case, for example, an open door for communicating with the upper and lower floors is provided on the veranda floor or the like, and by opening the open door, the upper and lower floors are blamed. In addition, an emergency ladder or the like is suspended from the veranda, and the emergency ladder is used to blame the ground.

[0003]

According to the above-mentioned conventional configuration, there are the following problems. First, in the case of a configuration in which an opening door provided on a veranda floor or the like is opened, it is very difficult to open the door, and in particular, when various objects are placed on the veranda or the like. Was an open operation after removing them, and considering that it was an emergency, it was not an easy task. Also, in the case of a configuration in which the emergency ladder is hung down and descends to the ground, the work of taking out the emergency ladder and hanging it down is complicated,
Using it to get down to the ground was not always easy. Thus, in either case,
There were many problems in escaping quickly in an emergency to ensure safety, and improvements had to be made.

The present invention has been made based on such a point, and an object of the present invention is to provide a door device capable of quickly escaping and ensuring personal safety in an emergency such as an earthquake. Is to provide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In this embodiment, the present invention is applied to a so-called entrance door. FIG. 1 is a diagram of the door device according to the present embodiment viewed from the inside,
FIG. 2 is a view from the outside. First, there is a frame 1, which is composed of a pair of long pieces 1a, 1b and a pair of short pieces 1c,
1d, and a pair of these long pieces 1a, 1a
b and a pair of short pieces 1c and 1d are connected so as to form a rectangle. The frame 1 is fixed to an opening of the concrete structure 3.

An entrance door 5 as a door is mounted inside the frame 1. The entrance door 5 is provided with a frame portion 7 on an outer peripheral portion. As shown in FIGS. 3 and 4, the frame portion 7 is formed in a box shape from a thin aluminum plate, for example. Is hollow. Frame part 7
A hinge 9 is attached to the right side in FIG. It is opened and closed by rotating through these three hinges 9. A handle 11 is attached to a position slightly lower than a substantially central position of a left portion of the frame 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. By gripping and rotating these grip portions 11a and 11b, the locking projection 15 is rotated. The entrance door 5 can be opened by retracting from the frame 1 side. When the entrance door 5 is closed, the locking projection 15 automatically projects and engages with the frame 1 by the elastic force of an elastic member (not shown), thereby closing the entrance door 5. State is maintained. The key mechanism 13 rotates the knob 13a so that the locking projection 17 shown in FIG.
The door is locked (disabled from opening the entrance door 5) by projecting to the side and engaging. Incidentally, 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
3 allows the locked state to be released.

As shown in FIG. 1, a hydraulic mechanism 23 is mounted on the upper end of the entrance door 5 and on the right side in FIG. In other words, when the entrance door 5 is left open, it is automatically closed by the elastic force of an elastic member (not shown).
For example, when the entrance door 5 is left in an open state, it is possible to prevent the entrance door 5 from being rapidly closed by the elastic force of the elastic member, and to close the entrance door 5 at a gentle speed. It works to be able to.

An emergency door 25 is attached to the entrance door 5 having the above configuration. 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 has upper and lower hinges 27 and 29, and is rotatably attached to the frame 7 of the entrance door 5 via the hinges 27 and 29. (Single-opening method). A key mechanism 28 is attached to the emergency door 25 on the right side in FIG. The key mechanism 28 is, as shown in FIG.
9 and by rotating the knob 31
The locking projection 29 is inserted into and removed from the frame 7 of the entrance door 5.

The emergency door 25 is normally closed and locked by the key mechanism 28. If, for example, an earthquake occurs and the entrance door 5 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 configuration of the emergency door 25 will be described in detail. First, between the emergency door 25 and the frame 7 of the entrance door 5, a portion located outside the entrance door 5 includes:
As shown in FIG. 3, a sealing rubber body 33 is interposed.
The sealing 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 7. The hermetic rubber body 33 ensures air-tightness and liquid-tightness, and at the same time, has a soundproofing and insect-proofing (insect prevention) function.

A portion between the emergency door 25 and the frame 7 of the entrance door 5 and located inside the entrance door 5 also includes:
A sealing rubber body 35 is interposed. This sealed rubber body 35
Is also hollow, and is inserted so as to fill an annular gap between the emergency door 25 and the frame 7. The hermetic rubber body 33 ensures air-tightness and liquid-tightness, and at the same time, has a soundproofing and insect-proofing (insect prevention) function.
In other words, the hermetically sealed rubber body 33 and the hermetically sealed rubber body 35 as described above ensure dual airtightness and liquid tightness, and also exhibit soundproofing and insect-proofing (insect invasion) functions.

The left side of the sealing rubber body 35 in FIG. 3 is attached to the frame 7 of the entrance door 5, but the other three sides are attached to the emergency door 25. I have. This is to make the opening operation of the emergency door 25 smoother while maintaining the above airtightness, liquid tightness, soundproofing, and insectproofing (insect prevention) functions. That is, FIG.
On the middle right side, if the sealing rubber body 35 is attached to the frame 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, this is not the case, and the emergency door 25 can be easily opened. Further, the sealing rubber body 35 on the left side in FIG. 3 is appropriately deformed and does not impair the opening operation of the emergency door 25 at all.

As shown in FIG. 3, an upper left corner 25a of the emergency door 25 in the figure has a shape that is partially cut away. This is to prevent the corner portion 25a from being caught on the side of the sealing rubber body 33 when opening the emergency door 25, so that the smooth opening operation is not impaired.

The emergency door 25 itself has the structure described above. However, when the emergency door 25 is attached to the entrance door 5, it is necessary that the emergency door 25 cannot be seen from the outside. This is due to the aesthetic problem of the entrance door 5 and at the same time, there is a concern that an intruder may invade. Therefore, in this embodiment, as shown in FIGS.
To cover the outside of the boundary between the door and the frame 7 of the entrance door 5,
A so-called “mall” 37 is attached. Since the outside of the boundary between the emergency door 25 and the frame 7 of the entrance door 5 is shielded by the mall 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 simple entrance door 5. 1 and 2, reference numeral 41 denotes a peephole, and reference numeral 43 in FIGS. 3, 4 denotes a frame 1 and an entrance door 5.
And a hermetic rubber body inserted between them.

According to the present embodiment, the following effects can be obtained. First, in the event of an emergency such as the occurrence of an earthquake, when the entrance door 5 cannot be opened, the lock by the key mechanism 31 is released, and the emergency door 25 can be opened and escaped to the outside. Thus, it is possible to easily escape to the outside as compared with a conventional escape from a veranda 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 normal passage functions as the escape route as it is), it is extremely safe compared to the escape through the veranda etc. And it will be a certain blame. FIG. 5 shows how the entrance door 5 is opened and closed and how the emergency door 25 is opened and closed. Further, since the presence of the emergency door 25 is configured to be invisible from the outside by the mall 37, the entrance door 25
Thus, the aesthetic appearance is not impaired at all, and the intruder does not needlessly recognize the existence of the emergency door 25 to induce the intrusion. A hinge 2 provided between the emergency door 25 and the entrance door 5 side.
The emergency door 2 is mounted so as to be rotatable inward through the doors 7 and 29 and has a shape in which corners located on the hinges 27 and 29 and located on the outside are partially removed.
When the door 5 is rotated to be opened, it is possible to prevent the door 5 from being caught by the structure on the side of the entrance door 5, and to provide a smooth opening operation of the emergency door 2.
In addition, since the sealing rubber members 33 and 35 are interposed between the emergency door 25 and the entrance door 5 inside and outside, respectively, the sealing rubber members 33 and 35 allow airtightness, liquid tightness, soundproofing, and the like.
An insect repellent (prevention of insect invasion) effect can be obtained. Further, in the hermetically sealed rubber body 37 inserted inside, the hinge 27,
The side located on the 29 side is attached to the entrance door 5 side, and the other parts are attached to the emergency door 25 side, so that while maintaining the air-tightness, liquid-tightness, soundproofing, and insect-proof (insect invasion) effects, The opening and closing operation of the emergency door 25 can be facilitated.

The present invention is not limited to the above embodiment. For example, the entrance door 5 of the emergency door 25
Is not limited to the one-sided opening system as in the above-described embodiment, and various modifications such as a one-sided opening system from the opposite direction, a one-sided opening system in the vertical direction, a double door opening system, and a shutter system 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 same applies to the material and the like of each part. The emergency door may be made of wood, steel, or stainless steel. Further, in the above-described embodiment, an example in which the present invention is applied to a front door is shown, but it is needless to say that the present invention can be similarly applied to a door inside a building.

[0020]

As described in detail above, according to the door apparatus of the present invention, first, in a case where the door cannot be opened in an emergency such as an earthquake, the lock by the key mechanism is released. As a result, the emergency door has been opened and it has become possible to easily escape to the outside. In particular, in the case where the present invention is applied to a front door, in the case of escape through the front door, as a matter of course, an escape route is secured (since a normal passage functions as an escape route as it is), for example, Safety can be improved as compared with escape through a veranda or the like. Also, since the presence of the emergency door is configured so as not to be recognized from the outside by the mall, for example, when applied to a front door, the appearance of the front door is not impaired at all, There is no need to unnecessarily recognize the presence of an emergency door and trigger an intrusion. In addition, since the inside and outside portions of the sealing rubber are interposed between the emergency door and the door, respectively, the double sealing member including the inside and outside sealing rubber members inserted into the inside and outside portions is used. Air-tight, liquid-tight, soundproof, insect-proof (prevention of insect penetration)
The effect can be ensured. Also, in the hermetically sealed rubber body, the side located on the hinge side is attached to the door side, and the other part is attached to the emergency door side, so that it is air-tight, liquid-tight, soundproof, and insect-proof. The opening / closing operation of the emergency door can be smoothly performed while maintaining the (prevention of insect invasion) effect.
