Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an emergency escape device for a vehicle, and in particular, an emergency exit is formed in the vehicle body, and an emergency door is rotatably attached to the emergency exit using a hinge mechanism. , relates to an emergency escape device that allows escape by opening the emergency door.

[Summary of the idea]

In this invention, a folding ladder is held in a folded state inside a rotatable emergency door provided at an emergency exit for escape in an emergency, and the ladder is held in a folded state when the emergency door is opened. At the same time, the folding ladder can be unfolded to make it usable, and a safe escape can be made using the folding ladder.

[Conventional technology]

When a disaster occurs in a vehicle such as a sightseeing bus, passengers and crew members must urgently escape from the bus. To enable such escape, buses are usually provided with an emergency exit, and this emergency exit is usually covered by an emergency door. Therefore, when attempting to escape, the emergency door must be opened.

However, because the floor height of the cabins of tourist buses and the like tends to be higher, passengers must jump from a considerable height when jumping from an emergency exit to the ground.
Therefore, for example, as disclosed in Japanese Utility Model Application Publication No. 59-185177, a multi-stage telescoping sliding lever is held inside the emergency door, and when the emergency door is opened,
It has been proposed to extend the downhill lever and use it to escape.

[Problems to be solved by the invention] However, since such conventional emergency escape devices use a sliding rod, not everyone can use them easily.

The present invention was developed in view of these problems, and the purpose is to provide an emergency escape device for vehicles that can be easily used by anyone and allows for safe escape. It is something to do.

[Means for solving problems]

This invention forms an emergency exit in the car body, and
In this device, an emergency door is rotatably attached to the emergency exit using a hinge mechanism, and the emergency door is opened to facilitate escape.In addition to having a plurality of steps, the ends of these steps are connected to the next step. A folding ladder is provided which doubles as a connecting pin for the side plates, and a stopper is provided to prevent the lower side plate from rotating more than 180 degrees with respect to the upper side plate. A holding means for holding the ladder in the folded state is provided inside the emergency door, and a folding ladder is held in the folded state inside the emergency door.

[Effect]

Therefore, according to the present invention, in case of an emergency, it is possible to open this emergency door, unfold the ladder held in a folded state inside the door, and use this ladder to escape. This makes it possible for anyone to escape safely.

〔Example〕

The present invention will be explained below with reference to an illustrated embodiment.
Figures 1 to 3 show an emergency escape device for a tour bus according to an embodiment of the present invention. For example, an emergency exit 10 is formed on the right side of the body of the tour bus and on the rear side. has been done. This emergency exit 10
The lower end of the bus is at approximately the same height as the floor of the bus. And on one side of this emergency exit 10,
Emergency door 13 via a pair of upper and lower hinges 11 and 12
is rotatably attached, and the emergency exit 10 is normally closed by this emergency door 13. The upper side of the emergency door 13 is composed of a door window 14, and a folding ladder 15 is held in a folded state inside the emergency door 13 and below the door window 14.

A rod 16 is attached to the upper end of the folding ladder 15.
is installed, and this rod 16 is the emergency door 1.
It is rotatably supported by a pair of brackets 17 inside 3. 1 more folding ladder
5 has three steps 18, 19, 20, and the ends of these steps 18, 19, 20 also serve as connecting pins, and the folding It is becoming more and more popular. When the ladder 15 is folded as shown by the chain line in FIG. 2, the upper and lower ends of the folded ladder 15 are held by holding leathers 21 and 22, respectively. The ends of these leathers 21 and 22 are fixed to the inside of the emergency door 13, and a hook 23 is attached to the free end side, and the ladder 15 is held vertically by this hook 23. It's starting to lock up. Furthermore, emergency door 1
There are handles 24 and 25 on the inside of 3 above and below, respectively.
is about to be installed.

Furthermore, in this folding ladder 15,
As shown in FIG. 4, for example, among the upper and lower side plates 27 connected by a step 18, a stopper 25 is bent and integrally provided on the back side of the upper side plate 27. By contacting the back side of the upper end of the lower side plate 27,
The side plate 27 is prevented from rotating more than 180 degrees,
This prevents the steps 18, 19, and 20 from swinging when the ladder 15 is used. Note that instead of this configuration, as shown in FIG.
A protrusion 29 is formed on the side of the upper end of 7, and this protrusion 2
9 may come into contact with the stopper 28 to prevent the lower side plate 27 from rotating more than 180 degrees.

Next, how to use this folding ladder 15 having the above structure will be explained. In case of an emergency, if you want to escape from this bus immediately, close the emergency door 13 that closes the emergency exit 10 by closing it on the hinge 11,
12 as the center as shown in FIGS. 1 and 2 to open the emergency exit 10. Next, hook 2
3 and the folding ladder 15 held by the retaining leathers 21 and 22 is unfolded as shown by solid lines in FIGS. 1 and 2. In this state, the user can escape through the emergency exit 10 by putting his or her feet on the steps 18, 19, and 20 while using the handles 24 and 25. Therefore, it becomes possible to easily escape, especially when the floor of the bus is high.

Furthermore, in the vehicle emergency escape device according to this embodiment, when the emergency door 13 is in the open state,
It is designed to be held at an open angle by a locking stay 30. Therefore, the emergency door 13 does not swing during escape. In addition, the folding ladder 1 can be
5 is prevented from rotating more than 180 degrees, and when attempting to escape using this folding ladder 15, steps 18, 19, 20 are prevented from rotating more than 180 degrees.
are held stably without shaking.
Therefore, you can easily descend using this ladder.

Next, a modification of the above embodiment is shown in FIGS. 6 and 7.
This will be explained with reference to the diagram. In this modification, the folded ladder 15 is held by a catch 31 instead of the holding leathers 21 and 22, and the catch 31 made of spring steel is installed inside the emergency door 13. are attached respectively, and the catch 31 is elastically deformed by the inclined portion 32 on the tip side of the catch 31, so that the side plate 27 of the ladder 15 in the folded state is held in that state. Therefore, according to such a configuration, it is possible to simplify the structure of the holding portion that holds the ladder 15 in the folded state.

[Effect of idea]

As described above, the present invention is designed to hold a folding ladder inside an emergency door in a folded state. Therefore, according to the present invention, in case of an emergency, it is possible to open the emergency door, deploy the folding ladder, and use the ladder to escape, which can be done safely even in vehicles with particularly high floor heights. You will be able to try to escape.

Further, according to the present invention, the end of the step also serves as a connecting pin for the side plate of the next step, resulting in a foldable ladder that can be easily folded. Moreover, since such a folding ladder is held in a folded state by a holding means provided inside the emergency door, it can be easily stored.

Additionally, the folding ladder is equipped with a stopper to prevent the side plate of the lower tier from rotating more than 180 degrees relative to the side plate of the upper tier, so it is difficult to unfold the folding ladder and escape. In this case, the ladder will not wobble and will be held stably. Therefore, it is possible to descend safely using this ladder.
