Description

[Detailed Description of the Invention] [Field of the Invention] The present invention relates to a platform for vertical shooters, and in particular, to a vertical shooter platform that can be installed on a ship and lowered vertically from the ship to the water surface in the event of a ship accident that requires abandoning the ship. This relates to a platform that forms the landing area of a shooter.

[Background of the idea]

As shown in FIG. 1, such a vertical shutter has a vertically extending shutter body 1 of an arbitrary shape.
A platform 2 is provided at the bottom of the shutter body 1 and floats on the sea surface W. A ramp 3 is formed between the shutter body 1 and the platform 2 to ensure safety for evacuees who have descended vertically. It is now possible to get down on Platform 2.

A storage case 4 for storing the shutter is provided on the upper part of the shutter main body 1, and by opening this storage case 4, a folded vertical The shooter can now be dropped onto the water surface. At this time, the shutter main body 1 extends perpendicularly to the side of the ship S, and gas is automatically injected into the air bladder 5 of the platform 2 to expand it into a boat shape, forming the configuration shown in FIG. It is something to take. Further, an awning 6 is provided between the lower end of the shooter main body 1, the side end of the platform 2, and the end opposite thereto.
This is to prevent evacuee 9 from feeling afraid when he skis downhill.

Shooter body 1 of such a vertical shooter
has a protective body 7 forming the outer wall of the shooter body 1 and a cylindrical downhill body 8 housed coaxially within the protective body 7.

The slideway body 8 includes a slideway body main body 80 made of a strong cloth such as a long canvas, and the slideway body main body 8, as shown in a developed view in FIG. 2, for example.
The meandering runway fabric 81 is attached by sewing or the like to the runway body 80 to form a runway 83 as shown in FIG. 3. has been done. Further, the lateral end portions 82 of the main body 80 of the main body 80 are bonded together to form a columnar main body 8 (see FIG. 4).

As the evacuees slide down the meandering slideway 83 composed of the meandering slideway fabric 81 and the slideway main body 80, the downhill speed is reduced due to the meandering of the slideway 83, and the evacuees are guided safely to the ramp 3. , platform 2 is reachable.

The platform 2 for a vertical shooter as described above has an air bladder 5 for creating buoyancy in the platform 2, as is clear from FIGS. 1 and 5. In the platform 2 shown in FIGS. 1 and 5, the air sac 5 is composed of an upper air sac 50 and a lower air sac 51, and a floor cloth 10 is sandwiched between the upper air sac 50 and the lower air sac 51. The evacuee 9 can descend onto the platform 2 from the vertical shutter main body 1 via the ramp 3.

The platform 2 described above is not only a place where evacuees 9 from the ship alight as described above, but also a base for evacuating to a lifeboat (not shown) located near the platform 2. It is what it is. Therefore, the platform 2 has the function of allowing the evacuees 9 who have evacuated from the vertical shooter body 1 to disembark via the ramp 3 in a good manner, and also allows the evacuees 9 to easily transfer to a lifeboat or the like. It is necessary to have a suitable structure.

However, in the conventional platform 2 having a basic structure in which a floor cloth 10 is pasted between an upper air bladder 50 and a lower air bladder 51, when the evacuee 9 alights and a load is applied to the floor cloth 10, There is a tendency for sag 100 to form in the portion of the floor cloth 10 that receives the load. This tendency is remarkable when a load is applied to the central part of the floor cloth 10.

If the above-mentioned sag 100 occurs, the evacuee 9
It becomes difficult to stand up and walk, and therefore, when evacuating from the platform 2 to a lifeboat or the like, there is a disadvantage that it may not be possible to evacuate quickly and safely.

[Summary of the idea]

This invention was made in view of the above points,
To provide a platform for a vertical shooter in which the floor cloth attached to the lower part of the air sac of the platform does not sag, and therefore allows the platform to be quickly and safely transferred to a lifeboat or the like. The purpose is to

Therefore, the platform for a vertical shooter according to the present invention has a ring-shaped air sac for creating buoyancy, and a floor cloth is attached to the bottom of at least one of the air sacs so that evacuees can disembark. In vertical shooter platforms,
It is characterized in that the inner periphery of the air bag to which the floor cloth is attached at the bottom and the peripheral edge of the floor cloth are tightened by cords so that the floor cloth is always kept under tension. .

[Specific explanation of the idea]

Hereinafter, one embodiment of the present invention will be described based on the drawings.

As shown in FIG. 1, a vertical shooter using a platform 2 for a vertical shooter according to the present invention has a shooter main body 1 hanging parallel to the ship's ship's side, and a platform 2 provided at the bottom of the shooter main body 1. Furthermore, a ramp 3 is formed between the shooter main body 1 and the platform 2 to allow the evacuees 9 who have come out of the shooter main body 1 to safely get down to the platform 2 with a gentle slope. This is the basic thing. A tent 6 is attached between the platform 2 and the vertical shooter body 1 so that the evacuees 9 do not feel fear while sliding downhill.

The embodiment of the platform 2 used in such a vertical shooter has an upper air sac 51 and a lower air sac 51 stacked on each other as shown in FIG. It has a structure in which the floor cloth 10 is stuck between them. The floor cloth 10 allows the evacuee 9 to get off onto the platform 2.

Even in the conventional floor cloth 10, when the upper air sac 50 is expanded, the upper air sac 50
The dimensions are controlled so that the floor cloth 10 attached to the bottom of the floor is in tension.
Even if the dimensions are controlled in this way, it is difficult to prevent the sagging 100 from occurring when a load is applied. It goes without saying that the floor cloth 10 of the platform 2 according to the present invention is also preferably subject to the above-mentioned dimensional control.

After performing such dimensional control, in one embodiment of the present invention, as shown in FIG. The rope engagement loop 50
0 is formed. This rope engagement loop 50
0 are attached at predetermined intervals to a band-shaped base fabric 501 that is attached all around the inner circumference of the upper air bladder 50 by, for example, sewing.

On the other hand, a support cloth 101 having a convex cross section is provided around the entire circumference of the floor cloth 10, and a floor cloth tensioning loop 103 is intermittently provided on the convex portion 102 of this support cloth 101. , for example, is attached by sewing or the like. Although the rope engagement loop 500 and the floor cloth tensioning loop 103 are provided at positions facing each other in this embodiment, in the present invention, both loops 50
The position of 0,103 is basically not limited.

By inserting the cord 11 between the rope engagement loop 500 and the floor cloth tensioning loop 103 as described above and tightening the cord, the floor cloth 10 is pulled in the direction of the upper air sac 50, which is a good result. It is stretched across the lower part of the upper air sac 50 with a certain tension.

The method of tightening the cables 11 as described above is basically not limited in the present invention. For example, as shown in FIGS. 6 and 7, two cords 110 and 111 are prepared, and one cord 110 is first tied together with 112 that ties the tips of the cords 110 and 111 together. Pass through the rope engagement loop 500 from the upper side A, and then insert the lower side B.
The cable body 110 is inserted into the upper side C of the floor cloth tensioning loop 103 facing the lower side D.
Insert into the side. Furthermore, the cable body 110 is passed through the adjacent cable engagement loops 500 which are arranged intermittently from the upper side A' to the lower side B', and then from the upper side C' to the lower side D of the opposing floor cloth tensioning loop 500. Pass through '. In this way, the cable 110 is sequentially inserted between the cable engagement loop 500 and the floor cloth tensioning loop 103 formed at a position facing the cable engagement loop 500 (shown as a solid line in FIG. 7).

The other cable body 111 is connected to the floor cloth tensioning loop 10.
3 from the upper C side to the lower side D, and further from the upper side A to the lower side B of the rope engagement loop 500 facing this floor cloth tensioning loop 103,
Neighboring floor cloth tensioning loops 10 lined up intermittently
3 from the upper part C' to the lower part D', and then from the upper part A' to the lower part B' of the cable engagement loop 500.
Both loops 103 and 500 are sequentially inserted and tightened as described above (shown as two-dot chain lines in FIG. 7).

In this way, the cables 110 and 111 are sequentially connected to the cable engagement loop 500 and the floor cloth tensioning loop 10.
3 and tying the other ends of the cables 110 and 111 together, the cables 110 and 111 are connected to the upper part in a figure 8 shape as shown in FIGS. 6 and 7. Tighten the air bladder 50 and floor cloth 10. Therefore, the floor cloth 10 is pulled in the direction of the upper air sac 50 and kept under tension.

Since the floor cloth 10 can be maintained in a tensioned state in this way, the floor cloth 10 does not sag, and the evacuee 9 can quickly and safely get to the platform 2.
It will be possible to transfer to a lifeboat, etc.

One embodiment of the present invention has been described above, but
The present invention includes rope engagement loops 500 provided intermittently over the entire inner periphery of the upper air sac, and floor cloth tensioning loops provided on the floor cloth 10 at positions facing the rope engagement loops 500. Between 103 and 1
The present invention is not limited to the method of stretching and tightening the floor cloth, but the method is not limited to the method of tightening the floor cloth by tightening the inner circumference of the air bag to which the floor cloth is attached at the bottom and the peripheral edge of the floor cloth with a cable body, so that the floor cloth is always tightened. Basically, any configuration may be used as long as the configuration allows the device to be in a tense state.

[Effect of idea]

As explained above, according to the vertical shooter platform according to the present invention, since the floor cloth is tightened between the inner periphery of the air bag attached to the lower part and the periphery of the floor cloth by means of the cord, the floor cloth is always held in tension. Therefore, when an evacuee steps onto the platform, the floor cloth will not sag. Therefore, there is an advantage that evacuees can safely and quickly transfer from the platform to a lifeboat or the like.
