Description

[Detailed description of the invention] (Technical field of the invention) This invention is a suspension structure for an air chamber-like object, more specifically, for example, when it is mounted on a ship and is forced to leave the ship, it can be lowered vertically from the ship to the sea surface. This invention relates to a suspension structure for a vertical shooter platform.

(Background of the invention) As shown in Fig. 1, such a vertical shooter has a shooter main body 1 extending almost vertically to the ship's side S.
A platform 2 is provided at the bottom of the shooter body 1 and floats on the sea surface, and a ramp 3 is provided between the shooter body 1 and the platform 2.
is formed so that evacuees who have descended vertically can safely land on platform 2.

On the other hand, a storage case 4 for storing the shooter is provided on the upper part of the shooter main body 1, and by opening the storage case 4,
A folded vertical shooter can be dropped from the deck of a ship on which the storage case 4 is installed. At this time, the shooter body 1 extends perpendicularly to the ship's side, and gas is automatically injected into the air chamber 5 of the platform 2 to expand, forming a boat shape and forming the structure shown in FIG. It takes .

Platform 2 of such a vertical shooter
is swayed by waves, etc. For this reason, the cable body 6 is connected to the shooter body 1 so that the platform 2 or the vertical shooter body 1 is prevented from swinging as much as possible. As shown in the sectional view in FIG. 2, such a cable body 6 has a lower end 6.
1 is connected to the outer wall of the lower air chamber 51 stacked in two stages, and its upper end 62 is connected to the lower end of the vertical shutter body 1 and stretched. That is, the central portion 63 of the cable body 6 extends obliquely from the upper air chamber 52 and is connected to the lower end portion of the vertical shooter body 1. For this reason, there was a drawback in that the upper air chamber 52 of the air chamber 5 in particular could not maintain the original circular cross section A and was distorted along the cable body 6.

In particular, in such a conventional vertical shooter, as shown in FIG. 1, a ramp 3 is connected to the lower end of the shooter main body 1 so that evacuees can get off the platform 2. Such a ramp 3 needs to be connected to the platform 2 at a gentle angle so that the evacuees who have been decelerated within the shooter body 1 can safely descend onto the platform 2. For this reason, it was necessary to make the ramp 3 longer in the direction opposite to the ship's side. For this reason, the cable body 6a attached on the side opposite to the ship's side S is at a steep angle with respect to the vertical direction. There was a possibility that the distortion in the air chamber 52 would become large and the platform 2 would become unstable.

(Purpose of the invention) The invention was made in view of the above points,
It is an object of the present invention to provide a suspension structure in which the air chamber is less likely to be distorted in the cross-sectional direction when the air chamber-like object as described above is suspended.

(Structure of the invention) In order to achieve the above object, the suspension structure for an air chamber-like object according to the present invention is a suspension structure for an air chamber-like object in which a long air chamber filled with gas is suspended by a cable. , a cable body is connected to the outer wall of the air chamber-like object and an inner wall at a position opposite to the outer wall or near the inner wall, and both cable bodies are connected and integrated above the air chamber and suspended. .

According to the suspension structure of the air chamber-like object according to the present invention, the cables are connected to both opposing sides of the air chamber, and the two cables are connected and suspended above the air chamber. Even when suspended diagonally, there is an advantage that distortion of the air chamber is reduced.

(Embodiment) Fig. 3 is a side view of an embodiment of the air chamber-like suspension structure according to the present invention applied to a vertical shooter. It has an approach 7 coaxially connected to the shooter main body 1. The approach 7 is connected to the platform 2 so that evacuees can safely disembark on the platform 2.

As shown in a developed view in FIG. 4, such an approach 7 is constructed by attaching a meandering approach road body 72 in a meandering manner to form a meandering approach road 71 on a long and strong approach road main body 70. A fastener 74 is provided so that a landing opening 73 can be opened in the approach road 71 in the downhill direction of the meandering approach road body 72.

By configuring the approach road main body 70 to have an arcuate cross section, the approach 7 can have an evacuation exit in the downhill direction.

Since such an approach 7 is basically vertical, it has the advantage that it is not necessary to increase the length of the platform 2 in the transverse direction.

The rope body 6 according to the present invention is attached to the ship side of the platform 2 and the side opposite to the ship side, and the rope body 6a on the side opposite to the ship side is attached to the vertical shooter body 1.
On the other hand, the cable body 6b on the ship's side is connected to the approach path 7. Of course, the suspension structure according to the present invention is not limited to such a connection method.

Each of the cables 6a and 6b has a branched lower end 61, as shown in FIG. 5, and one lower end 611 is bonded to the outer wall of the lower air chamber 51 of the air chamber 5. The other lower end portion 612 is fixed to the floor surface 21 of the platform 2, which is integrally attached to the air chamber 5, by a mounting piece 22, and the lower end portions 611 and 612 are attached to the air chamber 5.
It is tied 613 above and is integrated. These lower ends 611 and 612 are mounted opposite each other and therefore
The air chamber 5 is sandwiched between the lower ends 611 and 612 of both cords.

In the above embodiment, the other lower end 612 of the cable 6 was connected to the floor 21 near the wall of the air chamber.
For example, the lower end 6
11, it is obvious that it may be connected to the wall of the air chamber.

According to the above-described suspension structure of the air chamber-like object according to the present invention, the upper air chamber 52 is held between the lower end portions 611 and 612 of the cable body, so that there is an advantage that the upper air chamber 52 is less likely to be distorted. In particular, when suspending a platform 2 having a vertical approach 7 as described above, the inclination of the cable 6a attached to the opposite side of the ship is gentle with respect to the vertical direction (the length in the ship direction is short). In combination with this, the distortion of the air chamber becomes significantly smaller.

(Effects of the invention) As explained above, according to the suspension structure of the air chamber-like object according to the invention, the air chamber is held in a state of being held by the lower end of the cable, so there is an advantage that the air chamber is less likely to be distorted. . Furthermore, since the cable is suspended at two points: the outer wall of the air chamber and the inner wall or near the inner wall, when applied to the platform of a vertical shooter, for example, it is possible to prevent rocking even better than before. Benefits also arise.
