Description

Inflatable Kayak {INFLATABLE KAYAK}

The present invention relates to an inflatable kayak, and more particularly, to an inflatable kayak, which requires no separate assembly and is installed only by air infusion in a relatively short time, thereby enhancing ease of use, folding the air after removing air, And to make it relatively easy to occupy a relatively small space.

In general, kayaks are small, lightweight vessels with athletes and sterns pointed and moving over one or more knots. As the level of living has improved recently, interest in kayaking has increased as a leisure sport.

The kayak is usually one or two passengers and is used for hunting in the summer. The skeleton of the hull is made of wood with a length of 7m and a width of 50cm. It is traditional to make the skeleton by attaching leathers that have no hair.

The kayak pilot is wearing a waterproof jacket, stretches his feet in a round hole in the middle of the boat, and sits as if holding the lower body and moving the kayak to move the kayak. The hull of kayak is so light that it can be carried by itself, it is fast and has low center of gravity so it can withstand high waves.

In recent years, an air-inflated kayak has been proposed and used. An example of such an inflatable kayak is shown in FIGS. 8 and 9, and the construction and operation of the latter will be described.

8 and 9, a conventional air inflatable kayak 100 includes a tubular hull 110, a frame 120, a forehead frame fixing portion 130, a stern frame fixing portion 140, a frame hanger 150 And a plate 160.

When the air is injected into the tubular hull 110, a plurality of air receiving portions 111 are inflated to form a passenger space 101 inside the hull.

Between the air receiving portions 111 of the tubular hull 110, the frames 120 supporting the tubular hull 110 in the forward and backward directions are positioned. Further, in order to further improve the rigidity of the hull, the frames 120 may be positioned along the front-rear direction on the outer surfaces of the air receiving portions located at the uppermost portion of the air receiving portions 111.

It is alleviated that the tubular hull 110 is vertically deformed by waves due to the frames 120 and both ends of the tubular hull 110 are prevented from falling down so that the front portion and the rear portion of the tubular hull 110 And the cross-sectional surface of the tubular hull 110 is kept in a "V" -shaped shape, so that the resistance with the water surface can be reduced.

The plate 160 serves to prevent the kayak 100 from being deformed in the lateral direction and improve the rigidity in the front-rear direction and the vertical direction. The plate 160 is positioned perpendicular to the longitudinal direction of the tubular hull 110 in a spaced space between the plurality of frame hangers 150.

The aft frame fixing portion 140 is opened to remove the frames 120 from the fore frame fixing portion 130 and the plate 160 is removed and then the air of the tubular hull 110 So that it can be stored.

However, the above-described conventional techniques have the following problems.

Conventional kayaks are structured such that a plurality of frames form a skeleton of the hull, so that the assembling and disassembling of the kayaks are very difficult and relatively long time is required, which is inconvenient in use.

Further, there is a problem that the frame, the forehead frame fixing portion, the stern frame fixing portion, and the plate are formed of a hard material such as a metal material or a synthetic resin, and occupy a lot of space for storage, storage or transportation.
