Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an evacuation device.

[0002]

2. Description of the Related Art As an evacuation device for securing an evacuation route from upper floors in the event of a fire or the like, for example, Jikkei 6-161
The one described in Japanese Patent No. 59 is known.

In this conventional example, the evacuation device has a folding ladder that is stored in a folded state in a storage box fixed to the roof of a building or a predetermined floor, and an operation unit installed on the ground floor. If you operate the operation unit when a fire occurs,
The folding ladder in the storage box extends downward to form an evacuation route from the rooftop to the ground.

[0004]

However, the above-mentioned conventional example has the following drawbacks. In other words, the expanded ladder is
For example, when it is positioned facing a window or the like that can be an opening for evacuation, it is possible to evacuate along the extended folding ladder through the window or the like, but in the above conventional example in which the folding ladder is lowered along the outer wall of the building. , The traveling path of the folding ladder that descends for expansion is close to the windows, etc., so there is a risk of colliding with evacuees leaning out of the windows or showing their faces while traveling for,
The folding ladder cannot be positioned facing these windows and the windows cannot be effectively used as evacuation openings.

It is also possible to extend the folding ladder at the closest position avoiding the front of the window in order to use the window as an evacuation opening, but in this case, when transferring to the folding ladder. In addition, it is unsafe because it requires a dangerous posture in which the body is twisted and transferred from the state where the body is leaned out from the window to the ladder on the side of the window.

Further, as a result of the traveling surface of the folding ladder being set close to the window or the like, it is possible to arrange the operating portion within the range in which the hand extends from the window or the like, and the folding ladder and the extended hand can be extended. Impossible because of the possibility of collision,
The operation unit needs to be arranged at a predetermined position on the ground floor or another floor. As a result, the use of the folding ladder is inconvenient because it cannot be operated from the emergency fire floor.

The present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide an evacuation device capable of directly transferring to an evacuation ladder from an evacuation opening.

Another object of the present invention is to provide an evacuation device that allows the ladder device to be easily operated from an evacuation opening on any floor.

[0009]

According to the present invention, the above object is to provide a front surface of the evacuation opening 3 of the building while maintaining a proper distance D from the evacuation opening forming surface 2 of the building by the traveling surface restricting portion 1. It is achieved by providing an evacuation device having a ladder device 4 for descending and expanding the ladder and a restricting body 6 for restricting the movement of the ladder device 4 after the descending from the outer wall 5 of the building.

In the present invention, the ladder device 4 is stretched or extended while traveling in front of an opening that can be the evacuation opening 3, such as a window, and after the expansion, the ladder device 4 is arranged in front of the evacuation opening 3. The expansion operation of the ladder device 4, that is, the traveling of the ladder device 4 downward, the traveling surface is regulated so that the traveling surface S is maintained at a predetermined distance D from the evacuation opening forming surface 2 such as the outer wall surface of the building. The traveling surface S of the ladder device 4 which is regulated by the portion 1 is prevented from approaching the evacuation opening forming surface 2 when the traveling surface S becomes less than or equal to a preset distance D.

As a result, if the distance D is set to, for example, the size of the tip of the head and the formation of the evacuation opening 3 in the posture of leaning out from the evacuation opening 3, the evacuation opening is sought for help. Even if the victim suffers from the neck from 3 and so on, he / she will not hit the ladder device 4 which is spreading.

Further, since the ladder device 4 in the expanded state is arranged in front of the evacuation opening 3, the disaster victim can directly transfer to the ladder device 4 without taking an unnatural posture.

Further, the ladder device 4 is prevented from moving in the direction away from the outer wall 5 of the building by the restricting body 6 in the completed extension state, so that the ladder device 4 is transferred to the ladder device 4 or the ladder device 4 is used. The ladder device 4 does not sway carelessly during this movement, and safe evacuation is possible.

In addition, in the present invention in which the predetermined distance D is maintained between the spreading traveling surface S of the ladder device 4 and the evacuation opening forming surface 2, even if the evacuation opening 3 is released, it will be expanded. Since there is no collision with the ladder device 4, the releasing portion 9 for releasing the storage posture of the ladder device 4 and extending the ladder device 4
Can be arranged near the evacuation opening 3 on each floor.

By disposing the release unit 9 on each floor in this way, for example, when a user on a predetermined floor who notices a fire or the like spreads the ladder device 4, the ladder device is spread in addition to the disaster victims on the floor. Victims on any floors above can use the ladder device 4 at the same time to evacuate, which is very convenient.
