Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an evacuation device, and particularly to a rescue bag temporary stop mechanism of the evacuation device.

A conventional evacuation device is shown in FIGS. 1 to 3.

In the figure, 1 is a storage box fixed to a building 2, and 3 is a suspension box that is rotatably attached to the storage box 1, is folded and stored in an inclined manner, and is rotated and expanded when in use to hold a rescue bag 4 suspended. The rescue bag 4 is wound into a coil and stored on the suspension fitting 3, and one end is attached to the suspension fitting 3.
It is fixed with rope etc. 5 is a front door fixed to the storage box 1, 6 is an anchor bolt that fixes the storage box 1 to the building 2, 7 is a bearing plate fixed to the storage box 1 by welding, etc.
The suspension fitting 3 is rotatably held by a rotating shaft 8.

9 is a hinge that rotatably holds the front door 5 to the outside;
The front door 5 is inclined so that the center of gravity of its own weight is located outside the hinge o.

11 is an electric lock for opening 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 tilting 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 not in use and is stored, the suspension fittings 3 are folded and lifted at an angle of 300 to 600, as shown in FIG.
The rescue bag 4 is wound into a coil and placed on the suspension fitting 3, and is stored 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 getting old. Further, during 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 outward, and its shape is maintained by the stay 12.

When the front door 5 falls down, the coiled rescue bag 4 is 305
It rotates on the suspension fitting 3 having an inclination of ~60 degrees and on the lower part 14 of the front door 5, and falls while unwinding the coil. The rescue bag 4 rotates on the inclined hanging bracket 3 and the lower part 14 of the front door 5, so if the front curtain 15 is not present, the second
As shown in the figure, it gains acceleration in the horizontal direction and falls in a nearly parabolic trajectory as shown by arrow A. If the rescue bag 4 falls in a parabolic manner as described above, the higher the building 2 in which the storage box 1 is installed, the farther the rescue bag 4 will fall from the building 2. In this case, if there is a nearby building, telephone pole, or electric wire on the opposite side, the rescue bag 4 may hit the building or get caught on the electric wire, making it unusable. However, the first act 1
5, the rescue bag 4 that has rotated on the lower part 14 of the front door 5 will be suspended by the front curtain 5 and suspended in the air immediately after falling from the tip of the lower part 14 of the front door 5. There is a pause, and the force applied in the horizontal direction disappears.

Therefore, when the electric lock 16 is opened a few seconds later, the front curtain 15 is separated from the electric lock 16 side, and the rescue bag 4 is moved from the suspended state to the second position.
It falls in the direction of arrow B in the figure, 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 bracket 3, but when the rescue bag 4 is falling vertically, the suspension bracket fixes one end of the rescue bag 4. 3 is rotated outward from the storage box 13 by the load of the rescue bag 4, and the folded part is expanded to maintain its shape.
Then, as shown in FIG. 3, the rescue bag 4 is suspended.

As described above, the bag temporary stop mechanism consisting of the front curtain 15 and the electric lock 16 plays an important role in suspending the rescue bag 4 in the descending space.

The present invention is a further improvement of the bag temporary stop mechanism described above, and one embodiment thereof will be described below with reference to FIGS. 4 and 5.

In the figure, 18 indicates a bag temporary stop mechanism. 19
is a shaft supported by a bearing plate 20 provided in the open part of the storage box 1, and the bearing plate 20 is attached to a frame 25 on the front door 5 side at the upper end of the storage box 1.

A pair of hooks 21 are fixed to the shaft 19 by welding or the like, and a belt 22 is hooked to loops attached to the hooks 21 on both sides of the open end of the front curtain 15.

A latch receiver 23 is fixed to the shaft 19 by welding or the like, and has a through hole 23a.

24 is a latch built into the electric lock 16 fixed to the frame 25 of the storage box 1, and when not in use, this latch 24 always protrudes from the electric lock 16 with a spring (not shown) as shown in FIG. , into the through hole 23a of the latch receiver 23.

The latch 24 can be electrically actuated by a solenoid, or the spring can be manually retracted by a manual cable 26 to release the latch 24 from the latch receiver 23. Next, to explain the operation, when the front door 5 is opened during use, the rescue bag 4
rotates on the suspension fitting 3, falls, and is suspended by the front curtain 15. A part of the dead weight of the rescue bag 4 acts on the front curtain 15,
Since the looped belt 22 at the open end of the front curtain 15 is hooked on the hook 21 of the shaft 19, the front curtain 15 holds the rescue bag 4 in a suspended state. Thereafter, a timer is activated and the electric lock 16 is activated several seconds later. In other words, when the solenoid is energized to move the latch 24 backward in the Rotate. As the shaft 19 rotates, the looped belt 22 latched to the latching part 21 comes off and the front curtain 15 is opened, whereby the rescue bag 4 is rewound and falls directly below. Note that by pulling the manual rope 26, the latch 24 is moved to the latch receiver 23.
Of course, it is possible to open the front curtain 15 by retracting it from the front. As described above, according to the present invention, there is a shaft that rotates by electrically or manually releasing the latch, and a part of the front curtain is hooked to this shaft, and the front curtain is released when the shaft is rotated. By providing a bag temporary stop mechanism with a hook part that allows the rescue bag to be temporarily stopped in the air when the rescue bag falls,
This can prevent the rescue bag from falling away from the building.

This has the effect of ensuring that the rescue bag reaches the ground without getting caught on obstacles.
