Description

[0001] An amphibious boat with trailer [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an amphibious boat having a trailer, and more particularly, to a boat which can be used for amphibious operation without requiring a separate trailer, .

Generally, a boat refers to a means of transport that can travel on a water surface by a propelling means such as a furnace screw by having a large buoyant force. In particular, in the case of a leisure boat stored on the ground, Without a trailer, it would be difficult to transport on the ground.

Therefore, conventionally, it is necessary to carry a boat to a pier or a coast near to a trailer, then to put it on the surface again, and then to put it on a trailer and move it to a storage place. Therefore, there is a lot of inconvenience in moving and storing, There is a problem that a large amount of maintenance cost is required.

Therefore, conventionally, in order to solve the above-mentioned problems, many boat which can be operated on land have been proposed. Among them, 'prefabricated amphibious hovercraft' of Registration Utility Model No. 20-0398990 and 'amphibious boat' of Laid-Open Patent No. 10-2012-0013753 are known, and the construction of these is schematically described as follows .

That is, the 'assembled amphibious hovercraft' has a skirt body having a tube accommodating part formed with a plurality of openings at its bottom, an air injection bag integrally formed at the upper part for supplying air of strong force from the engine, A foldable body supporting device that is folded and coupled to an upper surface of the skirt body, an engine driving device provided behind the foldable body supporting device, a chair support and adjustment device coupled to the center of the foldable body supporting device, A chair coupled to the chair support and adjustment device, and a steering lever for driving the driver.

However, the above-mentioned Patent Registration No. 20-0398990 'assembled amphibious hobo crest' has a problem that a part of the air outputted from the engine flows into the air injection bag and the skirt body and can be moved up from the water surface or the ground by a predetermined height, There is a problem that the ride feeling is lowered and the direction change is not smooth. Further, when the air inflating bag and the skirt body are damaged during storage or operation, it is difficult to operate and lead to safety accidents.

In addition, in the 'amphibious boat' described in the patent publication 10-2012-0013753, the first and second fastening portions, to which the first and second wheels are fixed, respectively, are rotated at a predetermined angle, Are equipped with first and second wheels driven by a hydraulic motor on both sides of the bow and stern so that they can run smoothly on the ground. However, since it is a structure in which the wheels are directly attached to the hull, all the load of the hull is received by the wheel coupling portion during operation, which is not only very weak but also difficult to manufacture. Also, it has a disadvantage that it is not favorable because it does not take into consideration convenience of use for fishing and watering and utilization as residential use at camping.
