Description of the Related Art Doors that partition the inside and outside of a building or the inside and outside of a room like entrance doors have a certain amount of surface on a door frame due to external force during an earthquake or heat during a fire. Even if internal deformation occurs, the opening and closing performance is provided. However, if deformation exceeding a certain amount occurs, opening and closing cannot be performed, so that the door cannot escape from the room to the outside through the door.

[0003] When the door body cannot be opened or closed, escape is possible by storing the emergency escape door in the door body as shown in Japanese Utility Model Laid-Open No. 59-17992 and Japanese Utility Model Laid-Open No. 62-180187. However, in these examples, the height of the emergency escape door is about half of the height of the door body, so it is necessary to pass through in a crooked posture in an emergency, making it difficult to quickly escape.

[0004] Further, since there is no means for locking the emergency escape door from the outside of the room, it is not possible to prevent intrusion after the escape, and thus the security property is lacking.

In addition, since the locking device for locking and unlocking the door body and the locking device for locking and unlocking the emergency exit door are separately installed, there is a problem that the location of the locking device for the emergency exit door is difficult to be understood in an emergency.

In particular, in the event of a power outage, it is difficult to find an emergency exit door locking device that is not operated at all during normal times, so that it is difficult to respond urgently.

In view of the above, the present invention proposes a door with an emergency exit door which does not require a groping search for the position of a locking device for the emergency exit door even during a power failure.

According to the first aspect of the present invention, the locking device for locking and unlocking the door body is also used as the locking device for the emergency exit door, so that the location of the locking device for the emergency exit door can be easily understood even in an emergency. Then, it is possible to prevent a situation in which the position of the locking device for the emergency escape door is searched by groping during a power failure.

The locking device protrudes from the door body toward the vertical frame on the door end side, and locks the door body to the opening frame.
An operation that protrudes from the door body to the emergency escape door side and locks the emergency escape door to the door body, and an operation that selectively operates one of the main body engagement portion and the escape door engagement portion. The operating unit has a main body engaging portion that is normally in or out of operation during normal times, and an emergency door engaging or retracting operation is in operation in an emergency.

The operating unit of the locking device for unlocking the emergency escape door in an emergency is the same as the operating unit of the locking device for the door body that is used from normal times, so that the locking device can be operated even in the event of a power failure. This eliminates the need for a search operation and enables an emergency response.

In the case where the locking device is installed at two places on the upper side and the lower side of the door main body as described in claim 2, both the door main body and the emergency escape door are double-locked from the indoor side in normal times. It can be put in a state where it has been set, and the security performance in normal times improves.

According to a third aspect of the present invention, the operation unit of at least one of the locking devices installed at two places of the door main body can be operated from the outdoor side. After the emergency escape door is unlocked from the indoor side and escaped, the emergency escape door can be locked from the outdoor side, and the security performance after escape is improved.

When both the operation units of the upper and lower locking devices are made operable from the outside of the room, the door body and the emergency exit door can be placed in a double locked state when going out, and the security performance in the absence is improved. I do.

In addition, the emergency exit door is formed in a vertical shape along the outer shape of the door body, and the height thereof is set to be from the lower part to the upper part of the door body. It is possible to enter and exit from the opening of the vehicle, and it is possible to quickly escape in an emergency.

The emergency escape door is supported by the door body at the hanging side of the door body. If the emergency escape door opens and closes in the same direction as the door body, the emergency escape door is opened with the same feeling as the normal opening of the door. It is possible to escape smoothly.
