Description

[Detailed Description of the Invention] The present invention relates to an air port having an independent lateral air chamber inside the main body air chamber, which has shape retention, absorbency, and easy attachment of the lateral air chamber.

Conventionally, there has been a shape-retaining air port in which a main body air chamber and a side air chamber are integrated and communicated with each other, as shown in FIG.

However, in such an air port, the main air chamber and the side air chamber are tightly integrated, and the force shown in the figure (A,
B, C, etc.), so when this type of air port is used for the purpose of going down a river, etc., it will not be crushed by external forces when it gets caught in rapids or comes into contact with rocks, etc. Not only did this cause the passengers to become unbalanced, but the increase in external force created a risk of the main air chamber bursting.

In addition, such a conventional integrated air port,
Sufficient reinforcement treatment is required to prevent air leakage at the joint between the main body air chamber and the side air chamber.
This led to an increase in work time for reinforcement processing.

The present invention aims to solve the problem of the conventional air ports having poor absorbency and to provide an air port that can be easily assembled into a side air chamber.

That is, in the air port of the present invention, an independent side air chamber is arranged inside the opposing main body air chamber so that the ends of the side air chamber are in contact with each other, and there is a gap between the main body air chamber and the side air chamber. A mounting seat is provided in which two flexible seat base materials are overlapped and joined only at approximately the center, and one seat base material of the mounting seat is placed inside the main body air chamber, and the other seat base material is placed inside the main body air chamber. It is characterized in that the sheet base material is fixed to the end of the lateral air chamber via an adhesive.

Embodiments of the airport of the present invention will be described below based on the drawings.

As shown in Fig. 2 A, two flexible sheet base materials 1 and 1' such as rubber-covered cloth are overlapped, glued together only at the center using adhesive, and then sewn in a circular shape using thread 2. Or,
As shown in Fig. 3 A2, the sheet base materials 1 and 1' are overlapped and glued together only at the center with adhesive, and the cross section V
A mounting seat 4 is shown in FIGS. 3 and 4, in which two sheet base materials 1 and 1' are firmly joined by pasting a letter-shaped reinforcing tape 3 around the central portion with an adhesive. As shown in the figure, an end portion 7 of a side air chamber 7 independent of the main body air chambers 6, 6' in an air port having a bottom cloth 5 made of a material such as rubber-coated cloth and opposing main body air chambers 6, 6'. / , 7/, one seat base material 1 of the mounting seat 4 is placed inside the main body air chambers 6, 6', and the other seat base material 1' is placed between the end portion 7 of the side air chamber 7. It is fixed to 'Hz7'' via adhesive 8.

The air port of this invention uses an adhesive to secure the main body air chamber and the independent side air chamber using a mounting seat that is made by overlapping two flexible sheet base materials and joining them almost only in the center. Therefore, the independent side air chamber is reinforced to the main body air chamber, and the fixed joint between the main body air chamber and the independent side air chamber is a point-connected joint, so it is independent of the main body air chamber. The side air chamber has a certain degree of freedom, and deforms as it adapts to the pressing force of severe external forces such as when going down a river.It absorbs the pressing external force, protects the occupants from balance, and allows the main body air chamber to deform. This also reduces the risk of bursts.

In addition, the air port of this invention uses an extremely simple mounting structure in which two flexible sheet base materials are overlapped and joined only at the center of the seat, so an independent side air chamber is created. It takes only a short time to attach the side air chamber to the main body air chamber, and has the advantage that an independent side air chamber can be installed at a desired position as shown in FIG.
