Description

[Detailed description of the invention] Industrial application field The present invention relates to a suspended inflatable life raft. There are two methods: one is inflated on board the ship and is then lowered to the water surface with evacuees on board.The present invention belongs to the latter. It is.

Conventional Technology There have been various kinds of suspended inflatable life rafts as described above, but all of them tend to make the shape of the raft unstable when suspended, easily cause damage to the raft, or are difficult to use in an emergency. It was dangerous to handle. This type of hanging life raft is not suitable for safety standards.
When carrying 20 people, it is required to be able to withstand a load of 6.3 tons, but inflatable life rafts made of rubber-coated fabric usually deform or break due to the load when suspended. such as making it easier to
This resulted in various drawbacks. For example, Jikko 41-
In No. 24594, a pneumatic beam is provided on the bottom fabric in order to eliminate this drawback, but since the center part is separated, if the load is concentrated in the center part, it will curve downward. 1 of the air sacs arises
If the awning were to break, the shape would be severely distorted, and since the hanging rope is located outside the awning, there is a possibility that it could get caught on other parts of the hull during an emergency suspension. It was strong and highly dangerous.

Problems that the invention attempts to solve This invention attempts to solve the problems mentioned above.The invention aims to solve the problems mentioned above. It will not bend or deform even if it is added to the fabric, and the hanging member will not get caught on other parts of the hull even when suspended in an emergency. The aim is to enable safe hanging work.

Means for solving the problems In order to solve the problems mentioned above, the present invention
An inflatable annular air column is fixed to the outer periphery of the bottom fabric, and an inflatable column is erected in the center of the bottom fabric, and the upper end of this column is the apex, and the top surface of the bottom fabric is covered from the annular air column with an awning. In this, there are a plurality of outer hanging members whose ends are fixed to the outer periphery of the annular air column and are located along the inner surface of the awning, and a plurality of outer hanging members whose ends are fixed to the surface of the bottom fabric between the pillar and the annular air column. and an inner circumferential hanging member are integrally tied together with the awning at the top of the awning to form a hanging part and also form a retractable extension part in a part of the awning.

Function Since the present invention is constructed as described above, the inflatable life raft can be inflated on board a ship, evacuated people can be loaded onto it, and then the hook of a crane or the like can be hooked to the hanging part and the raft can be suspended to the water surface. , a plurality of outer periphery hanging members whose ends are fixed to the outer periphery of the air column and are located along the inner surface of the awning, and a plurality of inner periphery suspension members whose ends are fixed to the surface of the bottom fabric between the pillar and the annular air column. Therefore, the load is dispersed, and the load does not concentrate only on the central part and cause the central part to dent, as in the conventional case, and the central part can be prevented from deforming by the inner suspension part. can. In addition, although this deformation of the bottom fabric can be prevented by the inner hanging members, the awning that is tied together with the outer hanging members and the inner hanging members will also be pulled strongly. Since a telescopic extension part is formed in the tent, this extension part expands along with the extension of both hanging members, and does not put a burden on the tent that could cause damage. Furthermore, since the outer suspension members and the inner suspension members are located on the inner surface of the awning, in the event of an emergency suspension, these suspension members will not get caught on other parts of the hull. It enables safe use.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. 1 is a bottom cloth, and a plurality of air chambers 2 are made of rubberized cloth.
, and on the outer periphery, two upper and lower inflatable annular air columns 3 formed of rubber-coated cloth are fixed, and in the center part, formed of rubber-coated cloth.
An inflatable column 4 is erected and fixed. This pillar 4
A living room 6 is formed by covering the upper surface of the bottom cloth 1 with an awning 5 whose upper end is the top and whose lower end is fixed to the annular air column 3. Further, a plurality of outer periphery hanging members 7 are fixed at both ends to the outer periphery of the annular air column 3, and are positioned along the inner surface of the awning 5 toward the upper end of the struts 4, and are fixed diagonally at equal intervals. The outer circumferential hanging member 7 is fixed to the annular air column 3 in the upper annular air column 3.
After inserting each end into the loop threading patch 20 fixed to the ring, the fixing patch 21 fixes both ends diagonally to the lower annular air column 3, and the fixing patch 21 and the annular air column 3 The outer periphery of the adhesive part is covered and fixed with an anti-wear patch 22, and the annular air column 3 is
It prevents wear and tear. Furthermore, a plurality of inner suspension members 10 are fixed diagonally at equal intervals on the surface of the bottom cloth 1 in the center between the annular support 4 and the annular air column 3 using fixing patches 8, and between the patches 8. A protective patch 9 is used to reinforce the connecting portion. In addition, the inner hanging member 10 and the outer hanging member 7 are tied together with the awning 5 at the top of the awning 5 using a binding string 11 to form a hanging part 12 that engages a hook such as a crane. Configure. Furthermore, a stretchable extension part 13 is formed at the upper end of the tent 5, and this extension part 13 bends the upper end of the tent 5 by a certain width to form a bellows-shaped part 14, so that strong pulling tension is not applied. A stretchable rubber cord 15 is fixed to the inner surface to prevent deformation as much as possible. Further, the inner circumferential hanging member 10, which has both ends fixed to the bottom cloth 1, is fixed in position by being inserted toward the upper end of the support column 4 in the central direction by means of a band passer patch 16. Further, the support column 4 and the annular air column 3 are connected by an air guide pipe 17 that introduces gas such as carbon dioxide gas filled from a filling device.

In the configuration as described above, after the inflatable life raft is inflated and inflated on board the ship, and evacuees are placed on the bottom fabric between the annular air column 3 and the fixed part of the inner suspension member 10, If you hook the hook of a crane or the like to the hanging part 12 and suspend it to the water surface, the annular air column 3
A plurality of outer periphery hanging members 7 whose ends are fixed to the outer periphery and are located along the inner surface of the awning 5, and whose ends are fixed to the surface of the bottom cloth 1 in the center between the pillar 4 and the annular air column 3.
The load is distributed by the plurality of inner suspension members 10, and the load is not concentrated only in the center and dented the center as in the conventional case. The member 10 can prevent downward deformation. Further, although this deformation of the bottom cloth 1 can be prevented by the inner circumference hanging member 10, the awning 5 that is integrally tied together with the outer circumference hanging member 7 and the inner circumference hanging member 10 also
As it stretches, it becomes strongly pulled.
When both the hanging members 7 and 10 are made of nylon cloth with a width of 50 mm, the outer hanging member 7 will stretch by about 10% and the inner hanging member 10 will stretch by about 15%. Since the awning 5 is also stretched, if this tension exceeds the limit of the tensile strength of the awning 5, damage will occur. Since the extension part 13 is formed by the bellows-like part 14 and the rubber string 15,
This extension part 13 extends with the extension of both hanging members 7 and 10, and does not place a burden on the awning 5 that could cause damage, allowing safe use.

Effects of the invention Since the invention is constructed as described above, the inflatable life raft is inflated on board the ship, evacuees are loaded onto it, and then a hook such as a crane is hooked to the hanging part and the raft is suspended to the water surface. In some cases, the load is distributed by multiple outer suspension members and multiple inner suspension members, and the load is concentrated only in the center as in the past, causing the center to become dented. The center portion can be prevented from deformation by the inner circumferential hanging portion. In addition, even if there is a strong tension on the tent, since a part of the tent is formed with a stretchable extension part, this extension part stretches along with the extension of both hanging members, and the tension of the tent that may cause damage is prevented. I don't have anything to do with it. In addition, since the outer circumference hanging members and the inner circumference hanging members are located on the inner surface of the awning, in the event of emergency hanging, these hanging members will not get caught on other parts of the hull. It enables safe use.
