Description

Variable assembly members for amphibious boat}

The present invention relates to a set of a variable member for assembling an amphibian boat, and more particularly, to an amphibian boat by attaching a variable reinforcing member to the hull of the hull and installing members to perform the function of an amphibious boat on the reinforcing member. It relates to a variable member set that can be produced.

In order to store small vessels, they can be transported to the owner's house through a separate trailer or stored at a separate cost for the docks. There is an economic penalty in which the boat is damaged in the event of a natural disaster. There was a problem.

Recently, it has been developed in technology related to amphibious ships and is entering the commercialization stage, and has been used as leisure or military equipment. An example of a commercially available technology is the amphibian of Gibbs Technologies Limited, which corresponds to a combination of water motorcycle and automobile technology.

The conventional amphibian has been designed in a way to cut a portion of the lower hull for the contraction and deployment of the drive, which is a factor to lower the operating performance in the water.

The prefabricated amphibious hovercraft disclosed in the Republic of Korea Registered Utility Model Publication No. 20-0398990 as a conventional technology for improving this, has a tube receiving portion formed with a plurality of openings on the bottom, air for receiving a strong force air from the engine Skirt body integrally formed in the upper portion of the injection bag, a tube embedded in the tube receiving portion, a foldable folding body support device coupled to the upper surface of the skirt body coupled, the engine driving device installed in the rear of the foldable body support device , Chair support and adjustment device coupled to the center of the folding body support device, the chair is coupled to the chair support and adjustment device and consists of a structure including a control lever for the driver to control the driving.

However, the prior art as described above, although a portion of the air output from the engine is introduced into the air injection bag and the skirt body can be moved to a predetermined height from the surface or the ground, but the ride is less comfortable because the vehicle is not in close contact with the surface or the ground. There was a problem that the conversion is not smooth. In addition, when the air injection bag and the skirt body is damaged during storage or operation, it is difficult to operate and lead to a safety accident.

In addition, most existing amphibious vehicles are used only for special purposes such as military use. Therefore, due to the high price due to the vehicle structure, appearance, and special functions, it is impossible for the general public to utilize them.

Due to the current expansion of water sports, demand for amphibious vehicles is increasing. In addition, the development of amphibian vehicles has been actively carried out. However, existing amphibious vehicles do not meet the demand for amphibious vehicles equipped with a reasonable price, convenience of water and land operations, stability of the hull and vehicle design.

In addition, existing amphibian vehicles generally have a foldable wheel (wheel) system. This foldable wheel system is driven on the principle of folding the wheels and raising them to the front of the hull when the amphibian vehicle is moving underwater.

However, these amphibious boats are very expensive and difficult to be purchased by the general consumer and need to be manufactured in an inexpensive manner.
