BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency escape device for a bus, and more particularly to a device for safely using passengers and occupants in a bus accident or a natural disaster when the passengers or occupants are to escape from the vehicle in an emergency. The present invention relates to an emergency escape device for a bus that can be escaped from the bus.

[0002]

2. Description of the Related Art Various large-sized buses currently operated (for example, shared buses, sightseeing buses, etc.) have a vehicle body for urgently escaping passengers and occupants from inside the vehicle due to bus accidents or natural disasters. It is compulsory to provide emergency exit doors at the side or rear, referred to as exits or emergency exits.

Incidentally, the emergency escape door provided on the side or rear of the vehicle body as described above is provided at a considerably high position (for example, at a position of 1 m to 1.5 m) from the road surface. After opening the door, passengers and occupants jump off the road from inside the vehicle or escape using a rope ladder provided at the exit or emergency exit.

[0004]

However, since there is a considerable distance between the opening of the vehicle body where the emergency escape door is opened and the road surface as described above, especially the elderly, children and the physically handicapped. If a stranger was a passenger, it could not easily escape, and there was a danger of falling from the vehicle on the road and causing injury.

[0005] The present invention has been devised in view of such conventional problems, and can be used quickly and especially by ordinary adults, especially elderly people, children and people with physical disabilities.
It is an object of the present invention to provide an emergency escape device for a bus that can safely escape.

According to the present invention, to achieve the above object, a door body is pivotally mounted on a lower end portion of the door body as a fulcrum toward a lower part outside the vehicle body. When the door body is turned and opened,
The gist of the present invention is that an escape slide made of a foldable flexible material is provided along the inner side surface of the door body, which is inflated and extended by pressurized gas.

[0007] The escape slide may be formed to have a concave cross section when expanded and extended by pressurized gas. It is also possible to form a bulge for standing. Further, on both side edges in the longitudinal direction of the escape slide, a handrail for an escaper that can be erected when the escape slide is inflated and extended is provided, or on a side surface of the escape slide that contacts the inner surface of the door body. It is also possible to use a reinforcing fiber.

The present invention is constructed as described above, and is an emergency escape door provided on a side or rear portion of a vehicle body when a passenger or an occupant escapes from the inside of a vehicle in an emergency such as a bus collision accident or a natural disaster. At the same time as the lower end of the door body as a fulcrum, the escape slide is inflated and extended by the pressurized gas along the inner wall surface of the door body.

As a result, an escape slide-shaped bridge (escape slide) is formed between the opening of the vehicle body with the door body opened and the road surface, so that passengers and occupants do not jump off the vehicle from the interior of the vehicle to the slide. It is possible to escape from the vehicle quickly while sliding on the bridge.
