2. Description of the Related Art A conventional means for escaping a vehicle such as a train or a train of a personnel transportation system in the case of an emergency is a conventional vehicle in the case of a plurality of vehicles or a train connecting a number of vehicles. Means for opening the doors at the frontmost, which is the driver's cabin, and the rearmost, which is the normal conductor's office of the rearmost vehicle, to guide and escape to the track, for example, Japanese Patent Publication No. 4-59187, "Emergency Escape The invention of an "exit device" and the invention of a "vehicle emergency escape device" in Japanese Patent Publication No. 58-7499 have been proposed. In addition, as a means of escaping passengers from the vehicle, the rescue vehicle is opposed to the frontmost vehicle or the rearmost vehicle so as to be connected to the opponent's vehicle, the front and rear doors of each facing vehicle are opened, and Temporary delivery bridges are installed between the front and rear doors of the vehicle to guide the personnel and transfer them to the rescue vehicles. However, in any of the above-mentioned escape means, in a train in which a plurality of vehicles are connected, a large number of passengers rush to the front and rear, and it is not possible to safely and quickly escape in a short time. On the other hand, in parallel tracks such as double tracks and double tracks, the rescue train is placed next to the accident train in parallel, the entrance doors of each car are opened, and an emergency exit bridge is opened between the opened entrance doors. To guide the personnel and transfer the passengers to the rescue vehicle. In this case, if the rescue vehicle has an entrance door at the same place as the accident train, many passengers can be transferred to the rescue vehicle from many entrance doors at a time, so that many passengers can be rescued in a short time. However, in the case of a rescue vehicle having no entrance door opposite to the entrance door of the accident train, a large number of entrance doors cannot be opened at once. Further, in a single track orbit having a separation zone in the center, rescue trains cannot be rescued side by side as described above. As described above, it is difficult for the conventional means to safely escape the passenger from each vehicle in a short time in an emergency. In addition, the conventional emergency stairs for escape are often installed in the passenger cabin inside the vehicle, but when they are installed in the passenger cabin etc. in this way, it is necessary to provide a dedicated emergency exit at a specific position There was a problem that the passenger room became narrow.

In a conventional vehicle passenger escape system, an emergency exit door and a place where safety escape aids such as stairs and a shooter are installed are limited to a specific vehicle in a train. Limited to a particular location of the vehicle. Therefore, in an emergency, passengers of all vehicles could not safely escape in a short time. In particular, the height of the floor of the vehicle is higher than the track surface, usually 1.35 m to 0.85 m, so in order to safely escape passengers, stairs consisting of multiple steps corresponding to the height are required. It was necessary to provide safety fences and handrails on both sides of the stairs. However, if these structural members are not reduced in volume,
Due to restrictions on the storage location, the installation location of emergency exit doors for emergency use is limited.

[0004] Therefore, the present invention utilizes the opening of a normal passenger entrance door for each vehicle of the train, and a plurality of passenger entrance doors on each of the left and right sides of each vehicle. An emergency evacuation device is provided at the passenger entrance door at a location, and the volume is reduced and stored in a compact state at the lower part of the vehicle floor of the entrance door at normal times. Therefore, it is normally installed at the lower part of the vehicle floor at normal times. Therefore, it is a standby emergency escape device that does not make the cabin of each vehicle narrow and does not impair the appearance of the vehicle.In an emergency, the escape device stored from outside the vehicle is easier than the storage box. It is an object of the present invention to provide an emergency escape device having a staircase that can be pulled out, assembled easily, opened a doorway for a passenger, and guided to escape a passenger safely.

As described above, the present invention is an emergency escape device which makes it possible to use the entrances on both sides of each vehicle as emergency exits. Emergency escape stairs can be freely set up on the side where there is no. Therefore, the emergency escape of the passenger can be made from the side of the train on the safe side. In addition, assembling the stairs of the emergency escape device can be installed by trained crew members from outside the vehicle, so that it is possible to safely guide and escape passengers. Furthermore, since an emergency escape device is installed under the floor of the normally used entrance / exit for each vehicle, an emergency staircase can be installed in each vehicle, so that a large number of passengers can simultaneously escape from each vehicle quickly and quickly. I can do it. This emergency escape staircase is made simple and lightweight, and its operation is simple and can be assembled by light work.The emergency staircase is folded back and overlapped to reduce the volume and make it compact, The present invention has excellent effects not found in the conventional apparatus, such that it can be installed under the floor of the vehicle body structure because it does not require a place.
