In particular, the lowermost end of a number of telescopically extended hollow sliding tubes is intended to be easily, quickly and reliably set into service. Although the hollow sliding pipe is free, the ladder is prevented from wobbling, and is stable even in gusts of wind, allowing for safe evacuation. It has been widely used in.

However, the evacuation device with the extendable ladder disclosed in the US patent has a unique structure to be installed on the outdoor floor slab or balcony of a building, and when in use, it is used to connect the upper and lower floors. The structure required a means of communication.

In addition, under these circumstances, the
A balcony-type evacuation device as shown in Publication No. 29495 has also been proposed, but this evacuation device has a fixed ladder and the evacuation exit is always open, so it cannot be used when not in use. At that time, each floor had access to each other and people could go up and down freely, so there was a risk of falling through the evacuation door at night, and there was also a risk of illegal entry through the evacuation door or ladder.

The purpose of this invention is to first attach supporting members for fixing the outdoor floor to the outer wall of the building in advance, so that the outdoor floor can be easily attached to the outer wall of the building without performing large-scale construction. In particular, the object is to provide an evacuation device that is easy to install in new or under construction as well as existing buildings.

Another object of the present invention is to make it possible to form an evacuation route that connects the upper part and the part directly below in the vertical direction without fixing the lower end of the evacuation equipment when it is in use, that is, in the lowered and extended state. The operation for setting the evacuation equipment to the state is simple, quick, and reliable, and the evacuation equipment is prevented from wobbling.
It is stable even in gusts of wind, making it possible to evacuate with peace of mind.The outdoor floor also has a wide evacuation area in front of the opening formed in the outer wall of the building, spanning the entire width of the opening. The goal is to provide evacuation equipment that can evacuate large numbers of people.

A further object of the invention is to provide an evacuation device that can be made into a unit, improve productivity in a factory, have a simple structure, be manufactured at low cost, and be easily transported.

Furthermore, it is an object of the present invention to be arranged vertically on the outer wall of a multi-story building, installed on each floor of the building, and usually independent for each opening, without impairing the appearance of the multi-story building. It can be safely used as a balcony, and when used, it can connect each floor to each other, or it can connect multiple adjacent floors to each other among all the floors of the building. The purpose of this invention is to provide an evacuation device that greatly enhances its applicability to buildings.

To solve these problems, the evacuation device of the present invention includes a support member that is fixed in advance to the outer wall of the building along the lower part of the opening formed in the outer wall of the building, and a support member that is fixed to the outer wall of the building in advance. It is equipped with a pair of suspension rods arranged outwardly from the overall width and fixed in advance to the outer wall thereof, and has an evacuation opening on one side with a width extending outward from both sides of the opening, and an outdoor floor with an evacuation area formed in the remaining portion; fixing fittings for fixing the outdoor floor to the exterior wall provided on the outdoor floor at a position facing the support member; A hanging rod holder that supports the end of the hanging rod, a fence placed on the outdoor floor,
A top cover that opens and closes the floor side opening of the evacuation port, and an extendable evacuation device that is installed on the outdoor floor so that it is stored in the evacuation port in a contracted manner when not in use, and extends downward when in use. Accordingly, the outdoor floor is connected and fixed to the supporting member of the outer wall using the fixing metal fittings, and the front end thereof is fixed to a pair of hanging rods provided on the outer wall.

In addition, the upper and lower evacuation devices can be set to use without being interlocked with each other, preventing trouble from occurring during the setting operation of the evacuation devices, and making the setting operation of the evacuation devices extremely easy. In addition, the evacuation equipment can be carried out quickly and reliably, especially since the evacuation equipment is in a descending and extended state and is hung on the outdoor floor in a rigid form, even though its lower end is free. This prevents the evacuation equipment from wobbling and keeps it stable under gusts of wind, alleviating fear during evacuation and making it possible to evacuate safely and with peace of mind. By creating a wide evacuation area in front of the opening formed in the exterior wall, a large number of people can evacuate in a short time. The installation becomes extremely simple and easy to install in new or under construction as well as in existing buildings, especially if the evacuation device is installed in a multi-storey building, openings must be made in the external walls of each floor. However, since it is equipped with a fence as a protective measure, the opening feels like a window and does not spoil the appearance of the building, thus making it highly applicable to buildings. Moreover, when installed in a multi-story building, it is not only possible to construct an evacuation route that connects each floor when in use, but also allows for the construction of evacuation routes that interconnect multiple floors of the building. It is now possible to configure evacuation routes that connect the
In addition, the upper and lower floors can be connected without the need for interlocking means, and can be used as a balcony when not in use.Furthermore, it is unitized, lightweight, improves productivity in factories, and has a simple structure. By making it into a unit, production costs are reduced,
In addition, it is easy to transport, and the installation work is simple, reducing the installation period. Normally, the evacuation equipment is stored, the top cover is closed, and the outdoor floor is separated from other balconies, so there is no risk of illegal entry, and it is safe and used just like a regular balcony. There is an effect that it can be done.

However, from the specific examples of the present invention described above with reference to the drawings, various modifications and changes will be readily apparent to those having ordinary knowledge in the technical field to which this invention pertains. Furthermore, the structure of this invention can easily be converted into an embodiment essentially the same as that of this invention, in which the structure of this invention satisfies essentially the same tasks as that invention, and achieves the same effects as that invention. It could be replaced.
