Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inflatable chute or slide device (hereinafter simply referred to as a slide device), and more particularly to an inflatable chute or slide device (hereinafter simply referred to as a slide device).
The present invention also relates to a slide device that can be used on ships and is particularly suitable for quickly and safely evacuating passengers to lifebuoys in the event of a ship being in distress.

Conventionally, an inflatable slide device used for evacuation purposes, for example, on a ship, has been constructed as shown in Figures 1 to 3.

That is, the conventional slide device 1 for ships includes a slide portion 3 constituted by a main air chamber 2, and a core? When the slide assembly M1 is in a strip-like state when contracted, it is wound into a so-called sushi-maki shape to form a storage container divided into two parts. It is housed in 6. Storage container with 6
is a cradle 8 installed on the deck of the hull 7, with spaced apart rails 9a inclined toward the sea surface.
, come onto that rail of the pedestal 8 having 9b,
ing.

This frame 8 is pivoted to the sides of both rails so that the storage container 6 on the rail 9a and Ob will not fall naturally due to the tilting of the rail, and is connected to the peripheral side of the storage container 6 in a tangential line. A stopper rod 10 extending in the direction is provided. One end of the two stopper rods 10 is connected by a connecting rod 11, and one end of each of breakaway wires 12a and 12b extending from the storage container processor 11ll is fixed to the connecting rod 11. A cylinder 14 for inflating the slide section 3 and the platform section 5 via a filling hose 13 is arranged in the space below the rails 9a and 9b constituting this pedestal 8, and one end of the cylinder 14 is connected to an opening/closing cock section. The other end of the operating cable 15 connected to the storage container 6 is connected.

When the sliding storage container 6 is supported on the pedestal 8, the detachment wire 12a is removed when the slide device 1 is used.

By automatically or manually opening 12b, the support of the cyst flange rod 10 is released, so that the storage container 6 rotates and falls on the rails 9a and 9b toward the sea surface. 1
As a result, the slide section 3 and the platform section 5, which are housed in a roll in the storage container 6, unravel and fall to the sea surface 19 (FIG. 3). At this time, as shown in FIG. 2, the upper end of the slide section 3 is attached to the pedestal 8 by two hanging belts 17 in advance so as to prevent it from being stored in the storage container.
Therefore, this upper end becomes a fixed end to the hull 7. It's a trench, the storage container 6 is 1 to 3 meters from the pedestal 8.
When it falls, the operating rope 15 is pulled, and as a result, the cylinder 1
The cock part 4 is opened and gas is supplied to the main air chamber 2 of the resting platform part 3 and the float air chamber 4 of the grand i foam part 5 through the energetic hose 13, and these begin to expand and retain their shape.

However, when such a conventional slide device is released and deployed, the platform portion 5 dropped onto the sea surface 19 is shown in FIG. Tangled like this,
Or, the loading stand portion 3 may be twisted in the middle. Even if you fill yourself up in this state, you won't be able to get enough energy, and +;j
Even if you feel swollen in 7 minutes, the air chamber will twist,
fr, t at 2:), the hull 7 (1'-9) was bent upside down, or the chassis platform section 5 was turned upside down (4) [7] for emergency use. There was a concern that serious trouble would occur1.Also, when using the device at 1 o'clock in the sea with tidal currents, the platform part ξi was placed on a platform that could be pushed against the hull 7. I'm worried about the same trouble that I had before.)

Therefore, the object of the present invention is that when the retracted slide section and the platform section attached to the lower end of the slide section are dropped from a high place, they may bend due to wind or the like and interfere with the filling of the slide section. An object of the present invention is to provide an inflatable slide device that has no sharp edges and can be expanded into a predetermined perfect shape.
DESCRIPTION OF THE PREFERRED EMBODIMENTS The inflatable slide device of the present invention will be described in more detail below with reference to preferred embodiments particularly for use in ships, as shown in the accompanying drawings. In the embodiment of the present invention, the same or corresponding parts as in the conventional apparatus W described above are given the same reference numerals, and the explanation thereof will be omitted.

In FIGS. 4 to 8, an inflatable slide device according to an embodiment of the present invention is shown as a whole by reference numeral 20. This slide device 20 has a main structure similar to the conventional one described above. It includes a slide section 3 constituted by an air chamber 2 and a platform section 5 attached to the slide section 3 and constituted by a float air chamber 4.

In other words, when not in use, this sliding metal device i & 20 is stored in the storage container 6 in a manner that it is rolled up from the lower end, i.e., the folded portion, of the two IJl hanging parts. .

The device W23 connects the fixed end 21a of the slide portion 3 and the free end 22a of the platform portion 5 with the fifth
As shown in FIG. This cutting device 23 is
One connecting portion 25a includes a convex portion, that is, an insertion portion 24a.
and the other connecting part 25b, which has four parts, that is, an insertion opening 24b that fits into the insertion part 24a.

Both connecting portions 25a and 25b have a through hole 26 that passes through both connecting portions through the insertion portion 24a when the insertion portion 24a of one connecting portion is fitted into the insertion port 24b of the other connecting portion. It is formed. A cutting pin 27 is disposed within the through hole 26, thereby maintaining the connected state of both the connecting portions 25a and 25b. The cutting pin 27 is made of a spring pin or the like that cuts the connecting portions 25a and 25b with a constant load at 9 o'clock when both connecting portions 25a and 25b are pulled in opposite directions. On both sides of the other connecting portion 25b, where the through hole 26 is open, there is a sliding metal plate @2.
A cover 28 is attached to prevent the cutting pin 27 from coming out from the through hole 26 when the 0 is stored. This cover 28 is made of a tube-like material to cover the connecting portion 2.

The ends of these attachment belts 30a and 30b are connected to the hull side end 21a of the slide section 3 and the free end 22a of the platform section 5, respectively, with a rubber cloth seat 31 firmly fixed with rubber glue or the like. a, 311) with sewing thread 32. .

Next, the actual hf100 slipper device 20 according to the present invention
3. As shown in FIG. In the contracted state of the A-mesh, the slide portion 3 is bent in the middle by tJ1. In this state, the sliding metal device 20 is wound up into a sushi-maki shape from the bent portion of the sliding slide portion 3 and stored in the storage=1 antenna 6.

Such a storage container 6 is normally supported by the above-mentioned pedestal 8, and when the sliding metal device 2o is used, the release wires 12a, 12b are automatically or manually released, and the storage container 6 is attached to the pedestal. The sliding metal device 20 rotates and falls from the 8th part, and the sliding metal device 20 moves in a sushi-wrapped state from the inside.
It is suspended as shown in the figure. Sledding, te...
As already explained, since the cock portion of the cylinder 14 is opened by the hydraulic cable 15 when the storage container 6 has fallen a certain distance, the air starts to freeze even while the sliding metal device 20 is being unwound.

The live air chamber 2 of the slide portion 3 and the float air chamber 4 of the platform portion 5 in the sliding metal device 20 are in communication with each other,
In addition, side walls 16 that serve as handrails are provided on both sides of the slide portion 30.
is constituted by an upper air chamber, and this upper air chamber also communicates with the separated vital air chamber 2 through L2.

However, as the filling progresses, the whole expands and retains its shape, folded in two, as shown in Figure 7. Then, as the pressure in the air chamber increases and the shape retention of the expanded blade progresses, the fixed ends 2 of the slide portion 3 are folded in half and moved closer to each other.
The distance between 1a and the free end 22a of the platform portion 5 becomes tense, and the tension distance approaches the constraint dimension L of the cutting device 23 (approximately 200 to 500 mm in the case of the embodiment).

As the filling progresses further and the internal pressure of each air chamber increases,
Jllllllllllllll The internal pressure (100 to 150 man
When a force P corresponding to Hg) is reached, the lino cutting pin 27 of the cutting device 23 cuts by 7L by 1111] under the tension of both the connecting portions 25a and 25b. As a result, the connecting parts 25a and 25b are separated, and as a result, the slide part 3 is released from being folded in half, and the platform part 5 is placed at sea level 19.
The sliding metal device [20] is expanded to the internal pressure of the fully usable state as shown in FIG. Mt 20 is l1fl, 1
21i L/ /↓When almost completely expanded and retained its shape,
〆1q Due to the rigidity caused by the expansion of the slide portion 3, the slide portion 3 tends to become straight. That's no good, slide part 3
The connecting end 22b of the platform section 5 connected to the platform section 5 is pushed down into the sea as shown in FIG.
There was a drawback that the platform part 5 rotated and stood upright. In order to prevent this, one end of an elastic member 33 is attached to the connecting end 22b of the platform section 5, and the other end of the elastic member is connected to the slide section 3. This elastic member 33 is made of, for example, a rubber tape, and is applied with a predetermined tension T to the connecting side ψiM of the platform portion 5.
22b and the slide portion 3. , As a result, this slide device 20 is completely unusable.
:IJ is retained in a functional state.

As described above, according to the sliding metal device of the present invention, since the device is bent in two and connected by the separating device,
When it is dropped from a stored state, it is suspended in a two-fold state, and in this state it is filled with air and undergoes initial expansion and shape retention, after which it expands to a certain extent and then expands due to the internal pressure. Since the slide device is expanded by the destruction of the cutting bin of the cutting device that is pulled by force, the slide portion may expand while being twisted due to headwinds, crosswinds, or currents, or the d-platform !・It can prevent the inconvenience of the part facing the wrong direction or bending on the hull side. 3. Also, since the platform part and the slide part are connected by the iJ elastic member,
The inconvenience of the platform being upright and unstable can also be resolved. This makes it possible to improve the reliability of complete expansion during use of the slider device.

In addition, in the present invention, a cutting bottle is illustrated as an example of a cutting bottle with release or separation means of a cutting device and E-, but the present invention is not limited to such a cutting device. A tongue-shaped piece with Or, it engages with the opening 11 to completely prevent this withdrawal, but (2 or more)
When the pulling force F is applied, it may overcome the pressing force of the leaf spring and bend the leaf spring while releasing its connection and separating the two from each other.
