Description

[Detailed description of the invention] This invention is a vertical spiral sliding rescue bag (hereinafter simply referred to as a rescue bag) that is used for evacuation from high places such as high-rise buildings in the event of a disaster.

).

First, let's talk about the outline of the rescue bag, which is the main body of this invention.
This will be explained based on the diagram.

In the figure, 1 is a building, and 2 is windows provided on multiple floors of this building.

Reference numeral 3 denotes a holding metal fitting formed to project from the building after the rescue bag is dropped from the upper window (or roof) of the building vIJ1, and is also a part of the storage and dropping device.

Reference numeral 4 denotes the main body of the rescue equipment, in which a flexible inner cylinder cloth 5 and an outer cylinder cloth 6 are arranged concentrically, a sliding cloth 7 is sewn spirally in the gap between them, and the upper part is attached to the holding metal fitting 3. Fixed and suspended, upper entry way 8
Alternatively, an arbitrary number of entry paths 9 are provided along the way, and an exit 10 is provided at the bottom.

Therefore, since it is made of cloth, it is relatively inexpensive and easy to invest in. Moreover, since it is vertical, the space required for the evacuation device can be minimized, and it has the advantage of having the highest evacuation efficiency.

However, in the conventional rescue bag structure, problems arise due to the thickness of the building wall.

In other words, as shown by the solid line in Figure 2, there is no problem as long as the wall thickness is up to a certain level, but if it becomes thicker than that, as shown by the chain line, the boarding path 9 will become narrower, which may cause problems during evacuation. There is sex.

This invention solves the above-mentioned drawbacks by adding an ingenuity to the shape of the intermediate entry path 9 when attaching the intermediate entry path 9 to the outer sleeve cloth 6 of the rescue bag 4.

An embodiment of this invention will be described below based on FIG. 3.

FIG. 3 is an enlarged view of part A shown in FIG. 1, and the reference numerals in the figure are the same as those in FIG. 1 and indicate the same or equivalent parts, so the explanation will be omitted.

That is, as shown in the figure, the upper surface (side) of the midway boarding path 9, which has a cylindrical shape with an angular cross section, is installed horizontally, and the lower surface (side) is installed with an inclination as in the conventional method.

Therefore, the shape of the midway entry path 9 becomes wider in the shape of a funnel as it approaches the outer cylinder cloth 6 side.

In the rescue bag configured in this way, even if the wall thickness of the building becomes thicker, the passageway of the boarding path 9 will not be narrowed, so there will be no hindrance to evacuees' gliding, and it can be used even in an emergency. Easy to evacuate.

Moreover, since the number of types of entry paths 9 can be reduced, costs can be reduced.

Therefore, compared to the conventional shape of the intermediate boarding path 9, the effect is very large.

In addition, in the above explanation, it was explained that the upper surface of the intermediate boarding path 9 is installed horizontally, but although it is more effective if the upper surface is close to horizontal, the slope of the lower surface is steeper than that of the upper surface. If so, it is possible to put it into practical use.

[Brief explanation of drawings]

Figure 1 is a perspective view showing a partial cross-section of a rescue bag hanging outside a building, and Figure 2 is a partial cross-section showing the conventional shape of the boarding path 9.
FIG. 3 is an enlarged view of an intermediate boarding path according to an embodiment of this invention. In the figure, 1 is a building, 3 is a holding metal fitting, 4 is a main body of a spiral sliding type rescue device, 6 is an outer cylinder cloth, 7 is a sliding cloth, 10 is a lower escape port, and 12 is a boarding path.

Claims (1)

[Scope of utility model registration request] An inner tube cloth and an outer tube cloth in which flexible tube bodies are arranged concentrically,
In the gap between the inner tube cloth and the outer tube cloth, there is a sliding cloth arranged in a spiral shape, and a tube with a rectangular cross section that is attached by perforating the outer tube cloth and sewing around it. What is claimed is: 1. A rescue bag comprising a midway boarding path configured in the shape of a shape, characterized in that the midway boarding path is sewn to an outer cylinder cloth so that the slope of the lower surface of the midway boarding path is steeper than the top surface thereof.
