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, it can be used in buildings, elevated bridges, ships, etc. The present invention relates to a slide device suitable for quickly and safely evacuating people, etc. to the Shumei Ukifune.

Conventionally, inflatable slide devices used for evacuation purposes on ships, etc. are shown in Figures 1 to 3.
It was configured as shown in the figure.

That is, the conventional slide device 1 for ships includes a slide portion 3 constituted by a main air chamber 2, and a platform portion 5 attached to the slide portion 3 and constituted by a float air chamber 4. When the device 1 is in a belt-like state when contracted, it is wound in a so-called sushi-maki shape and stored in a storage container 6 divided into two parts. This storage container 6 is
A pedestal 8 installed on the deck of
A pedestal 8 having 10b is mounted on its rails.

This frame 8 is pivoted to the sides of both rails so that the storage containers 6 on the rails 10a and 10b will not naturally roll and fall due to the inclination of the rails, and extends in the tangential direction in contact with the surrounding side surfaces of the storage containers 6. A stopper rod 11 is provided. The upper ends of these two stopper rods 11 are connected by a connecting rod 12, and one end of each of breakaway wires 13a and 13b extending from the storage container 6 side is fixed to this connecting rod 12. Rails 10a that constitute this frame 8,
A cylinder 15 for inflating the slide section 3 and the platform section 5 via the filling hose 14 is disposed in the space below 10b, and one end of the cylinder 15 is connected to the storage container 6 at the opening/closing part. The other end of the operating cable 16 is connected.

A storage container 6 supported on such a pedestal 8
When using the slide device 1, the breakaway wire 13a,
By automatically or manually opening 13b, the support of the stopper rod 11 is released, so that the storage container 6 rotates and falls on the rails 10a, 10b toward the sea surface 9. 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 9 (FIG. 3). At this time, as shown in FIG. 2, the upper end of the slide section 3 is connected to the pedestal 8 by two hanging belts 17 before being stored in the storage container. It becomes a fixed end. When the vessel 8 is a ferry boat, for example, the fixed end of the sliding part from which the boat escapes is located at the boarding floor 7a, as shown in FIG.
It is installed on an upper floor 7b with a height H of 3 to 10 m, and receives the own weight and external force of the slide part 3 through a hanging belt 17 when the slide device 1 is dropped and when it is used.

Further, when the storage container 6 falls 1 to 3 meters from the pedestal 8, the operating cable 16 is pulled, and as a result, the opening/closing part of the cylinder 15 is opened and the filling hose 1
4, gas is supplied to the main air chamber 2 of the slide section 3 and the float air chamber 4 of the platform section 5, and these begin to expand and retain their shape.

However, when such a conventional slide device is released and expanded, the platform portion 5 dropped onto the sea surface 9 is exposed to the surface of the sea as shown in FIG. The slide portion 3 may become tangled as shown in FIG. 2 or may become twisted in the middle. Even if the air chamber is filled in such a state, the air chamber may not be filled sufficiently, or even if the air chamber is sufficiently filled, the air chamber may remain twisted.
There was a fear that it would break toward the hull 7 side, or the brat form section 5 would turn upside down, causing serious trouble during emergency use. In addition, when the device is used at sea with fast currents, there is also a concern that the same troubles as mentioned above may occur if the platform section 5 is pressed against the hull 7.

Therefore, it is an object of the present invention to prevent the retracted slide section and the platform section attached to its lower end from bending due to the wind or the like when dropped from a high place, thereby interfering with the filling of the slide section. An object of the present invention is to provide an inflatable slide device that can be expanded into a predetermined complete shape without causing any damage.

DETAILED 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, parts that are the same as or correspond to those of the conventional device described above are given the same reference numerals, and the explanation thereof will be omitted.

4-8, an inflatable slide apparatus according to one embodiment of the present invention is generally designated by the reference numeral 20. This slide device 20, like the conventional one described above, includes a slide portion 3 constituted by a main air chamber 2, and a platform portion 5 attached to the slide portion 3 and constituted by a float air chamber 4.
Contains.

The slide device 20 in this embodiment has an upper end 21a that is the end of the slide portion 3 on the hull 7 side, that is, the fixed end.
is connected to the pedestal 8 by two suspension belts 17, similar to the conventional device shown in FIGS. 2 and 3. Also, the free end 22a of the platform section 5 connected to and attached to the lower end 21b of the slide section 3, that is, the end of the platform section 5 on the attachment side with the lower end 21b of the slide section 3 is connected to one end 2.
2b, the opposite end and the upper end 21a of the slide portion 3, that is, the fixed end are 2 in the width direction.
They are closely connected to each other by two disposed cutting devices 23. Therefore, the slide device 20 is
After dropping this from the mount 8, if the slide section 3 and platform section 5 were not yet filled with air, the slide section 3 was folded in half and hung on the side of the ship's hull 7, as shown in Fig. 4. state. In other words, when the slide device 20 is not in use, it is folded in half and hung from the lower end, that is, the folded portion, and is stored in the storage container 6 in a sushi roll shape.

A separating device 23 connects the fixed end 21a of the slide section 3 and the free end 22a of the platform section 5.
are shown in FIGS. 5-7. This separating device 23 has one connecting portion 25a having a convex portion, that is, an insertion portion 24a, and a concave portion, that is, an insertion port 24a.
4b and the other connecting part 25b, which has an insertion opening 24b that fits into the insertion part 24a. When the insertion portion 24a of one connection portion is fitted into the insertion port 24b of the other connection portion, the insertion portion 25a, 25b is
A tapered through hole 26 is formed that passes through both connecting portions via 4a.

This tapered through hole 26 has a taper pin 2.
7 is inserted to prevent separation of both connecting portions 25a and 25b. And this taper pin 2
This taper pin 27 is inserted into the small hole at the tip of the tip protruding from the through hole 26 of No. 7 except at specified times.
Safety pin 28 to prevent it from slipping out of 6
is inserted. The material, shape, etc. of the safety pin 28 are selected so that it can be broken with a predetermined force (several kilograms) when the taper pin 27 is pulled out from the through hole 26 by the action described later.

Each connecting portion 25a, 25b is connected to the mounting belt 30 via a U-shaped shackle 29a, 29b, respectively.
a, 30b, these mounting belts 30
The ends of a and 30b are attached with sewing thread 32 to mounting seats 31a and 31b made of rubber cloth, which are firmly fixed to the hull side end 21a of the slide section 3 and the free end 22a of the platform section 5 with rubber glue or the like, respectively. Sewn and fixedly attached.

By the way, the taper pin 27 is also connected to the same U-shaped shackle 29c as described above at the end opposite to the end of the safety pin 28, and the shackle 29c is connected to the attachment belt 30c, and the attachment belt 30c is connected to the attachment belt 30c. 30c is fixed by sewing with sewing thread 32 to a mounting seat 31c which is glued to a part of platform portion 5 in the same manner as described above. Platform portion 5 to which the end of this mounting belt 30c is fixed.
As clearly shown in FIG. 5, when the slide device 20 is retracted and suspended on the side as shown in FIG.
2a is folded back once toward the slide portion 3 side in a bellows shape, and this is the side portion of the folded portion 33 facing outward of the folded S-shaped portion. That is,
Such a folded portion 33 approaches the cutting device 23 most from the side thereof.

As is clear from the above explanation, taper pin 2
7, when the platform portion 5 begins to expand as the slide device 20 is filled with air, and then the folded bellows-like portion begins to expand outward as shown in FIG. An acting force is applied to pull it out from the through hole 26 via the through hole 26.
Moreover, both connecting portions 25a and 25b are also connected to the slide portion 3.
As the platform section 5 expands, it tends to be separated. Therefore, the taper pin 27
The material and taper are such that the slide device 20 can withstand the impact force having a multiplicity of several G when the slide device 20 is dropped, and can escape from the through hole 26 by overcoming the frictional force caused by the tensile force of both the connecting portions 25a and 25b. Designed at an angle.

Next, the slide device 2 of the embodiment according to the present invention
The operation of 0 will be explained.

As shown in FIG. 4, this slide device 20 has a fixed end 21a of the slide portion 3 and a free end 22a of the platform portion 5 which are closely connected to each other by a disconnecting device 23, and which are connected to each other by a separating device 23. The free end 22a of the foam portion 5 is connected to the cutting device 23 as described above.
The free end 22a is partially bellows-shaped so as to connect a portion of the free end 22a to a taper pin 27 for automatically releasing the slide device 20 as the slide device 20 expands. Therefore, when the slide device 20 is in its contracted state, the slide portion 3 is bent in the middle as described above. In this state, the slide device 20 is wound up into a sushi-maki shape from the bent portion of the slide portion 3 and stored in the storage container 6.

Such a storage container 6 is usually supported by the above-mentioned pedestal 8, and when the slide device 20 is used, the release wires 13a, 13b are automatically or manually released, and the storage container 6 rotates and falls from the pedestal 8. The slide device 20 is unrolled from the inside and suspended in the state shown in FIG. 4. At this time, the impact force when the slide device 20 is stopped by the suspension belt 17 due to the head difference H from the gantry installation floor 7b to the slide boarding floor 7a becomes a gravitational acceleration of 3 to 8 G. Therefore, it is necessary that the suspension belt 17, the cutting device 23, etc. be manufactured so as to be able to withstand this impact force. For this reason, especially in the separating device 23, the tapered pin 27 is interposed to prevent unexpected separation due to this impact.

By the way, when the storage container 6 has fallen a certain distance, the cocking portion of the cylinder 15 is released by the operating cable 16, so that filling starts even while the slide device 20 is being unwound.

The main air chamber 2 of the slide portion 3 of the slide device 20 and the float air chamber 4 of the platform portion 5 communicate with each other, and side wall portions 18 serving as handrails are provided on both side edges of the slide portion 3 to communicate with the air chamber 2 of the slide portion 3. This upper air chamber also communicates with the main air chamber 2. Therefore, as the filling progresses, the whole expands and retains its shape, folded in two, as shown in Figure 7.
Then, the portion of the free end 22a of the platform portion 5 that is folded into a bellows-like shape unwinds its bellows due to expansion and begins to maintain its shape in a straight line. Provides pulling force.

As described above, when this pulling force overcomes the frictional force between the connecting parts 25a and 25b, the taper pin 27 begins to come out from the through hole 26, and then the safety pin 28 is cut by the pulling force of the taper pin 27. Then, the taper pin 27 is completely removed from both connecting portions 25a and 25b. As a result, the connection parts 25a and 25b are uncoupled and separated, whereby the two folds of the slide part 3 are released and the platform part 5 is extended toward the sea surface 9, and during and after that. 8, the slide device 20 expands and retains its shape to a fully usable internal pressure as shown in FIG.

By the way, when the slide device 20 almost completely expands and maintains its shape as described above, the slide portion 3 tends to become straight due to the rigidity of the slide portion 3 due to its expansion. Therefore, the connecting end 22b of the platform part 5 connected to the slide part 3
was pushed into the sea as shown in Figure 9,
There is a drawback that the platform section 5 rotates and stands up. To prevent this, an elastic member 34 is provided at the connection end 22b of the platform portion 5.
One end of the elastic member is attached, and the other end of the elastic member is connected to the slide portion 3. The elastic member 34 is made of, for example, a rubber tape, and acts to narrow the gap between the connecting end 22b of the platform portion 5 and the slide portion 3 by applying a predetermined tension T.
As a result, the slide device 20 is maintained in a completely usable condition.

In addition, in the above embodiment, the cutting device 23 is
The connection was maintained by a taper pin 27 connected to a part of the free end 22a of the platform part 5, but the direction of the force acting on the taper pin 27 when the platform part 5 expanded, Or, depending on the storage method, etc., it may become unstable to pull out. That is, the taper pin 27 is connected to the slide device 2.
There is a possibility that it will come off before the predetermined expansion level of 0 is reached. Therefore, another embodiment of the cutting device 23 can be configured as shown in FIG. 10.

In addition to the configuration of the separating device shown in FIG. 6, this separating device 23 has a through hole 35 that extends across the fitting portion of the two connecting portions 25a and 25b, that is, the convex portion 24a and the concave portion 24b. is formed, and the through hole 35
In addition, the internal pressure (100 to 150mm
When the force P corresponding to Hg) is reached, both connecting parts 25
Cutting pin 3 that can be cut by pulling a and 25b
6 has been inserted.

According to such a cutting device 23, when the slide device 20 starts to be filled with air and expands from the state shown in FIG. Even in this case, the connection between the two connecting portions 25a and 25b is not immediately released by the cutting pin 36. In such a case, as the slide device 20 expands, the disconnecting device 23 connecting the fixed end 21a of the slide portion 3 and the free end 22a of the platform portion 5 is pulled and tensioned from both sides. , 11th
As shown in the figure, the constraint dimension L of the cutting device 23
(approximately 200 to 500 mm in this example). Then, as the filling progresses further and the internal pressure of each air chamber increases, the tensile force P acting on the disconnection device 23 increases,
When the internal pressure of the slide device 20 reaches the above-mentioned level, the cutting pin 36 breaks and both connecting portions 25
The bond between a and 25b is released. According to such an embodiment, all the impact on the cutting device that occurs when the slide device is dropped is received by the taper pin.
The cutting pin will not be destroyed before its predetermined operation, ensuring stable operation.

As explained above, according to the slide device of the present invention, the device is folded in two and connected by a separating device, and the connecting portion is used as a cutting means of the separating device as the slide device expands. By providing a taper pin that can be pulled out from the container, even when the device is dropped from the stored state, the cutting device is not separated by the impact of dropping, and can be reliably suspended in a folded state. Next, in this state, filling is started and initial expansion and shape retention is performed, and after that, after the expansion and shape retention has progressed to a certain extent, the separating device is separated by the taper pin that is pulled out by the tensile force due to the internal pressure, and the slide device is formed. Because it is extended, it is possible to prevent the inconvenience of the slide section being twisted and expanding due to headwinds, crosswinds, or currents, or the platform section being turned in the opposite direction or bending toward the hull side. .

Further, since the platform part and the slide part are connected by the elastic member, the problem that the platform part stands up and becomes unstable during deployment can be eliminated. This makes it possible to improve the reliability of complete expansion during use of the slide device.
