Abstract

PROBLEM TO BE SOLVED: To quickly and safely perform an escape in a vehicle emergency. SOLUTION: A door 12 in a lower part of a door 11 in a front head part of a leading vehicle 10 is provided so as to rotate in the horizontal direction on the outside of the vehicle with a lower part serving as the base point, an emergency escape device 20 consisting of inflation material 21 inflated by injecting air is provided in the door 12. The doors 11, 12 are opened at emergency time, a cover 32 and the inflation material 21 are thrown to outside the vehicle, when air is injected in the inflation material 21, it serves as a chute for an occupant to slide. The chute has a protrusive part protruded upward in both sides of a slide surface sliding the occupant.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escape device provided for escape from a railroad vehicle when an emergency occurs.

[0002]

2. Description of the Related Art An emergency escape device for a vehicle is installed in a driver's cab or the like of a leading car of a train. The emergency escape device is a ladder. In an emergency, the ladder is lowered from the through hole in the forehead of the leading vehicle so that it can escape to the roadbed surface.

[0003]

In the conventional ladder system,
Placing the ladder on an unstable floor of the scaffold, and basically getting in a backward position when getting off the ladder, was a concern for the passengers who escaped.

It is an object of the present invention to secure passenger safety at the time of emergency evacuation and to speed up the evacuation.

[0005]

The object of the present invention is to provide a door which is provided so as to close a lower portion of an opening of a vehicle, and which is horizontally rotated outward from the lower portion as a base, and is fixed to the door. This can be achieved by configuring an emergency escape device for a railway vehicle from an inflating material that expands by injecting air.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. Doors 11 and 12 that are opened in an emergency are provided at the front head of the leading car 10 of the train. Under normal conditions, the escape device 20 is installed inside the door 12 below the door 11. The escape device 20 is intended to be inflated by injecting air into a chute that can be slid by an occupant. The escape device 20 is made of a bag-shaped inflatable material 21 that expands when air is introduced. The expansive material has a generally rectangular cylindrical shape. Normally, air is evacuated, wound and folded, fixed to the door 12 with a rope 31 and covered with a cover 32. The base end (upper end) of the expansion member 21 is fixed to the upper part of the door 12. Door 12
Is installed rotatably forward (outside the vehicle) with the lower surface of the passage as a base end. When the inflatable material 21 is inflated, convex portions 23 projecting upward are provided on both sides of the sliding surface 22 of the occupant to prevent the occupant from falling off. The protrusion 23 serves as a handrail. A sliding cloth 25 is provided on the surface of the sliding surface 22. The sliding cloth 25 is wound around the sliding surface 22 and the back surface of the expanding material 21 and installed by bonding or the like. As the sliding cloth 25, one having good sliding properties is adopted. When the inflatable material 21 is inflated, a pillow 24 is provided integrally with the lower portion of the inflatable material 21 so as to smoothly land on the roadbed surface 30 when sliding and landing.

When the door 12 is rotated to the outside of the vehicle, the upper surface of the door 12 can be walked. At this time, a support member that supports the lower part of the door 12 from the vehicle body 10 is provided, or a chain or the like that suspends the door 12 from above is provided so that the door 12 is in a horizontal direction. Cover 26
Is rotatably provided on the upper part of the door 12.

In an emergency, the doors 11 and 12 are opened to the outside of the vehicle, and the cover 32 is thrown out of the vehicle. The cover 32 hangs from the front end of the door 12. Next, rope 31
And throwing out the inflatable material 21 to the outside of the vehicle. Next, the air hose 35 provided on the vehicle side is connected to the air port 26 of the escape device 20.
And inflate the inflatable material 21 by injecting air. The expansive material forms an oblique chute. After getting on the door 12, the occupant slides on the chute 21 and descends on the roadbed surface 40. Since the occupant slides on the sliding cloth 25, the slidability can be improved and escape can be performed quickly.

According to this, since it is sufficient to open the door 12 and throw out the chute 21, it is not necessary to fix the chute or the like, and it is possible to escape quickly. Also, cover 3
No. 2 does not have to be removed, so that it is possible to escape quickly from this point.

[0010]

According to the present invention, it is possible to escape quickly.
