Description

[Detailed Description of the Invention] The present invention relates to a rescue bag device used for emergency escape from a building in the event of a fire or the like.

First, a conventional rescue bag device of this type will be explained with reference to the drawings.

FIG. 1 shows the dropping state of the first stage operation in the two-stage dropping method of the conventional rescue bag device.

In this figure, the installation floor of the storage and release device 2 for the building 1 is the 9th floor 3, and this storage and release device 2 has a belt-shaped rescue bag 4 with a length equivalent to nine floors, which can be folded as shown in the figure. The rescue bag 4
As shown in the figure, a midway entrance 5 is formed at a position corresponding to each floor of the building (excluding the first floor), and is folded in together with a rescue bag 4 as shown in FIG.

As shown in FIGS. 3 and 4, this folding method consists of a foldable rescue bag dropping suspension mechanism in which the rescue bag 4 is stretched out flat and the entrance 5 and upper end are stored in the storing and dropping device 2. A guide rope 6 tied to the 16 arms in FIG. 9 and with its lower end free is placed in the center of the rescue bag 4, and the rescue bag 4 is inserted halfway along the a-a line. Fold it over the entrance 5, then fold the rescue bag 4 halfway over the entrance 5, centering on line b-b, and finally c-
Fold it in half around line c to make it into the folded state shown in Figure 2.

When the rescue bag 4 is dropped in the first stage operation of such a rescue bag device, the opening force of the complementary ring 7 formed of a wire rope or the like located at the lower end of the rescue bag 4 causes the bag to open as shown in FIG. The midway boarding gate 5 and the midway boarding gate guide rope 6 come out from inside the rescue bag 4.

For this reason, when the halfway entrance 5 is located within reach as shown in Fig. 1, before the full length of the rescue bag 4 is dropped by the second stage operation, it may be mistakenly located at the halfway entrance on the wrong floor. 5 was set on the boarding tool 8 in the middle.

FIG. 1 shows a state in which the intermediate boarding gate 5 for the second floor is set on the seventh floor, which is the mid-boarding floor (see the imaginary line in FIG. 1).

In addition, since the boarding gate 5 on the way goes outside, the boarding gate 5 on the way
There was also a risk that the window glass would be damaged by the metal guard 9 attached to the tip of the window and connected to the midway boarding tool 8.

The present invention eliminates the drawbacks of the conventional ones mentioned above,
The purpose of this device is to provide a rescue bag device in which the entry port does not come out of the rescue bag during the first stage operation, and can be set at any distance from the top entry port in the longitudinal direction of the rescue bag. a first joint of a pair of velvet fasteners attached at at least one position at the terminal, and a first joint located above the first joint at the bottom of each of the plurality of release cords connected to the guide rope at the entrance. a second joint of a velvet-type fastener attached to the rescue bag opening restraint device, each intermediate entry being wrapped by the rescue bag;
The first and second joints of the velvet fastener are connected and housed, and the second stage operation creates a difference in height between the first and second joints of the velvet fastener, causing the velvet fastener to separate. The boarding entrance was made to open outside only when the train was opened.

The present invention will be explained below with reference to embodiments shown in the drawings.

Note that the same components as those of the conventional device described above are denoted by the same reference numerals in the drawings, and the explanation thereof will be omitted.

In FIG. 5, reference numeral 10 denotes a rescue bag opening restraint device for preventing the entry port 5 from opening midway through the folded rescue bag 4 at the part that exits from the storage/dropping device 2 during the first stage operation. This rescue bag opening control device 10 is installed at arbitrary intervals in the longitudinal direction of the rescue bag 4, and in this embodiment, for example, as shown in FIGS. 6 and 7, The first joint 12.1 of the velvet fastener is attached to the side of the rescue bag 4 on the opposite side of the bag 4 at a position below the mid-way entrance 5 with sewing thread 11 at intervals in the lateral direction.
2, and a rescue bag release control device 10 on the guide rope 6 at the entrance on the way.
Open cords 13, 13, . The distance H (seventh
It consists of a second joint 15 of a velvet fastener attached by means of a sewing thread 11 so as to be located upwardly as shown in FIG.

The first joint part 12 and the second joint part 15 of the velvet fastener can be joined and peeled off as is well known.

The folded state of the rescue bag 4, which exits from the storage/dropping device 2 during the first stage operation and has the entrance 5 on the way, is shown in FIG. 6, and this folding method is shown in FIG. As shown in FIG. 8, the rescue bag 4 is unfolded flat, the midway entrance 5 and the midway entrance guidance rope 6 are placed in the center of the rescue bag 4, and the release cord 13 is connected to the rescue bag 4. For example, the seventh
Pull it out to the left side of the figure, fold the rescue bag 4 along with the release cord 13 over the halfway entrance 5 around the a-a line, and then fold the rescue bag 4 around the bb line The opening cord 13 is folded over the opening 5 together with the extended portion, and finally folded in half along the c-c line to form the folded state shown in FIG.

Thereafter, the second joint attached to the extended end of the release cord 13 located outside the rescue bag 4 is guided to the first joint 12 of the velvet fastener, and the second joint 15 is joined to the first joint 12. I'll keep it.

In the first stage operation, the rescue bag 4 folded in this manner is in a folded state due to the joining force between the first joint 12 and the second joint 15 of the velvet fastener, as shown in FIG. Therefore, boarding gate 5 does not come out on the way.

In the second stage operation shown in FIG. Second joint part 15 of fastener
is positioned above the first joint 12 of the velvet fastener by a distance H, so that the weight of the rescue bag 4 below the rescue bag opening restraint 10 is transferred to the first joint 12 of the velvet fastener. Acting on the joint of the second joint 15, the velvet fastener is peeled off, the rescue bag 4 is released from its folded state, and the entry port 5 is taken out.

As described above, the rescue bag device according to the present invention includes a first joint of a pair of velvet fasteners attached at intervals in the longitudinal direction of the rescue bag, and a plurality of release cords connected to a guide rope at the entrance halfway. and a second joint part of a velvet type fastener installed above the first joint part at the bottom of each of the rescue bag opening restraints, and each intermediate entrance is located above the first joint part. Since the first and second joints of the velvet fasteners are wrapped and stored in an overlapping joint with each other, the mid-boarding exits in the first stage operation, and therefore the mid-boarding gate of the wrong floor is removed. It is possible to prevent serious accidents caused by installing the guard bar, and there is no risk of damaging the window glass due to the guard bar, which is an excellent effect.
