BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency evacuation device in a building or condominium, and more particularly to an emergency ladder device in a building having a simple structure and easy to operate.

[0002]

2. Description of the Related Art In recent years, the news of a large number of casualties caused by a fire in high-rise buildings and condominiums has often been reported in television news programs and newspapers. Those on the floor are vulnerable to damage. By the way, emergency passages of buildings and condominiums are often swallowed by fire smoke on the floor where the fire occurred and unable to pass, and tragic accidents such as evacuees died in smoke or burned alive while waiting for rescue. There are quite a few. Especially, in the case of a condominium, if window gratings are installed to prevent theft, these window gratings easily interfere with evacuation. On the other hand, in the case of high-rise buildings that do not easily jump to the ground without installing a window grid, disaster relief devices are not always installed on each floor, and once a disaster occurs, evacuees can get stuck. However, there are quite a few situations in which nothing can be done except waiting for the rescue of firefighters.

[0003]

In view of the problem of evacuation when a fire occurs in the conventional high-rise buildings and condominiums described above, the present invention can be used to quickly escape from the scene when a fire occurs. In addition, it is an object of the present invention to provide a portable and highly practical ladder ladder device that can be commonly used as a window grid and is highly portable.

[0004]

To achieve the above object, the present invention provides a rectangular box frame (20) for housing a rope ladder (30) to a lower frame (21) and the lower frame (21). Left and right frames (22, 23) which are upright on both sides of and have a storage chamber and whose cross-sectional shapes are symmetrical, and an upper frame (24) which is openably and closably covered at the upper ends of the left and right frames (22, 23) The left and right frames (22, 23) are provided with vertical openings (220, 230) facing each other, and the rope ladder (3

Each of the lateral locking grooves is opened, and the locking projections attached to the lower end of the peripheral surface of the insertion pin are locked in the locking groove so as to stop the movement of the insertion pin; In order to fix the cross rail to the wire rope, a stop ring is fixed to the upper and lower surfaces of the wire cross section on the peripheral surface of the wire rope penetrating while holding both ends of the cross rail at appropriate intervals. This is even more preferable.

[0006]

The present invention having the above-described structure, when a scandal or the like occurs once and it becomes impossible to escape through an ordinary passage, the upper frame of the rope is opened to fix the upper end of the rope ladder. If the rope ladder is fastened around a solid fixture, and the rope ladder is taken out of the box frame and hung outside the window, the evacuee can quickly follow the rope ladder and evacuate. If you insert the flanges at both ends of the rope ladder into the storage openings of U-shaped section formed on the inner surface of the left and right frames in an orderly manner, you can store and carry the rope ladder in the box frame regularly. It is convenient, and you can usually place it in a place where you can easily see it, and in an emergency, you can quickly carry it to the window and deploy the rope ladder to make it an evacuation passage.

Further, if the box frame body is formed by being joined to each other by an inner frame body and an outer frame body having an appropriate cross-sectional shape, or formed in other manners, and if the detailed structure is variously devised, it is usually possible. Can be used as a window grid, and the operation becomes more convenient and quicker.

The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description of the embodiments with reference to the drawings.
