Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an evacuation device using a rescue bag.

Conventionally, in this type of evacuation device, when using a rescue bag, the storage box with casters must be manually moved to the front, or the lid of the storage box must be opened to the front, and the suspension fittings or rescue bag must be lifted up by hand. From there, it moved in a semicircular direction toward the outside of the window, and was dropped outside the window (outdoors).

However, with such conventional evacuation devices, when there is a rush of evacuees, it is difficult to move or open the box, lift the hanging bracket or rescue bag, and drop it out the window. However, people with limited physical strength, such as the sick and elderly, were not able to carry out these tasks; however, they were unable to use the evacuation equipment that had been provided, and the fire and smoke could even cause casualties.

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional evacuation device, and aims to provide an evacuation device that can drop a rescue bag extremely effectively with a simple mechanism and operation. .

An embodiment of the present invention will be described below with reference to the drawings.

Fig. 1 is a partially cutaway side view showing the embodiment when stored, and Figs. 2 and 3 are partially cutaway side views when in use. storage box, 3
is a suspension fitting that is rotatably attached to the storage box 1, is folded and stored in an inclined manner, and is rotated and expanded during use to hold the rescue bag 4 suspended; the rescue bag 4 is wound in a coil shape. The suspension member 3 is mounted on the suspension member 3, and one end thereof is fixed to the suspension member 3 with a lobe or the like.

5 is the front door fixed to storage box 1, and 6 is the front door fixed to storage box 1.
An anchor bolt 7 is a bearing plate fixed to the storage box 1 by welding or the like, and a rotary shaft 8 holds the suspension fitting 3 rotatably.

Reference numeral 9 denotes a hinge that rotatably holds the front door 5 on the outside 10, and the front door 5 is inclined so that the center of gravity of its own weight is located on the outside 10 from the hinge 9.

11 is an electric lock for opening and closing the front door 5; 12 is a small lock on the lower side 14 of the front door 5 so that when the front door 5 rotates, the rescue bag 4 rotates and falls from the inside of the storage box 13; The stay 15 that provides the tilt and fixation is a front curtain whose one end is fixed to the tip of the lower part 14 of the front door 5 and the other end is connected to an electric lock 16 attached to the storage box 1.

In the above configuration, when the rescue bag 4 is stored when not in use, the suspension fittings 3 are folded and lifted to an angle of 30 to 60 degrees, as shown in FIG. is wound into a coil and placed on the suspension fitting 3, and is housed between the front door 5 and the front door 5, which is fixed with an electric lock 11 so as not to open forward.

The front curtain 15 is located between the front door 5 and the rescue bag 4, and the length of the front curtain 15 is such that the rescue bag 4 can rotate and fall and be held in the air at the tip of the lower part 14 of the front door 5. It's summery. In use, when the electric lock 11 is opened, the front door 5 rotates due to its own weight and the load of the rescue bag 4 and falls to the outside 10, and is retained in shape by the stay 12.

When the front door 5 collapses, the coiled rescue bag 4
Rotate and coil on the suspension fitting 3 with an inclination of 0 to 600 and on the lower part 14 of the front door 5! It falls while untying it. The rescue bag 4 has an inclined suspension fitting 3 and a front door 5.
Since it rotates on the lower part 14, if there is no front curtain 15, as shown in FIG.
As shown in the figure, it falls in a nearly parabolic trajectory.
J If it falls in a parabola like this, storage box 1
The higher the building 2 where the rescue bag 4 is installed, the higher the building 2
It will fall somewhere far away. In this case, if there are telephone poles or electric wires in a nearby building on the opposite side, the rescue bag 4 may hit the building or hit one or more electric wires, making it unusable. However, when the front curtain 15 is present, the lower part 14 of the front door 5
Immediately after the rescue bag 4 that has been rotating above falls from the tip of the lower part 14 of the front door 5, it is suspended by the front curtain 15 and stops temporarily in the air, and the force applied in the horizontal direction disappears.

Therefore, when the electric lock 16 is opened several seconds later, the front curtain 15 is separated from the electric lock 16 side, and the rescue bag 4 falls from the suspended state in the direction of arrow B in FIG. 2, that is, in the vertical direction. When the rescue bag 4 is suspended in the air by the front curtain 15, the second
As shown in the figure, since there is slack 17 in the rescue bag 4, the force due to the load of the rescue bag 4 does not act on the suspension fittings 3. However, when falling vertically, ``'' fixes one end of the rescue bag 4. The hanging fitting 3 is rotated from the inside of the storage box 13 to the outside 10 by the load of the rescue bag 4, and the folded part is expanded to maintain its shape, suspending the rescue bag 4 as shown in FIG. .

If the electric lock 11 can be operated by a push button switch provided at a location other than the location where the evacuation device is installed, remote control becomes possible.

Although the above embodiment shows a case in which the lower end of the front door 5 is joined by a hinge 9 and rotates forward, the same effect can be obtained even if the front door 5 is opened outward to the left and right as a double door type.

In addition, although the case in which the front curtain 15 is provided as a means for holding the rescue bag 4 in the air has been described, other similar means such as holding the front door 5 in a folded state or holding it with a robe etc. It is also possible to provide one. As described above, according to this invention, (1) it becomes possible to drop and expand the rescue bag without relying on human power;

(2) It can be dropped and expanded with one touch, and remote control is also possible.

(3) Since an external power source such as a motor or hydraulic pump is not required for dropping, the structure is simple, economical, and highly safe.

(4) When the rescue bag 4 falls, by temporarily stopping it in the air, the force applied in the horizontal direction is eliminated, and the rescue bag can be dropped vertically, so the rescue bag can hit obstacles. It is possible to reach the ground without any problems.

There are effects such as
