Description

PORTABLE AND DISMOUNTABLE CABIN

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a portable knockdown cabin and, more particularly, to a portable knockdown cabin whose floor, main walls and roof are all in a knockdown mode, portable while contained in a box and carried by a vehicle so that they can be assembled at any place such as travel destination, rest area, business destination, farm or workshop .

Discussion of Related Art

A conventional tent can be useful during a short journey in case of good weather. However, under heavy rain, water is soaked into the tent's roof and main walls no matter how well waterproof it is. Especially, because the tent is installed right on the ground, its moisture is soaked into its bottom so that it is very inconvenient of people to stay or sleep thereinside. Further, things may become wet to be damaged. For windy days, the tent is hard to be supported only by its poles so that it may be blown off. In the worst case, the tent falls down to become useless.

There are many condominiums for lease or parcelling out in famous sights or sight -seeing resorts, which are, however, installed fixedly on one place. For this reason, they cannot be used other than that location. It is also unfeasible to have and use several condominiums because of economic reasons .

A knockdown house was known, which must be fixed at a place where it is installed. It is not considered to be carried with a light weight. It is difficult to carry and thus must use a crane if the house is assembled or removed. Therefore, it is impossible to carry or install it while its installation location varies. SUMMARY OF THE INVENTION

Accordingly, the present invention is directed to a portable knockdown cabin that substantially obviates one or more of the problems due to limitations and disadvantages of the related art .

An object of the present invention is to provide a portable knockdown cabin whose floor, main walls and roof are all in a knockdown mode, portable while contained in a box and carried by a vehicle so that they can be assembled at any place such as travel destination, rest area, business destination, farm or workshop.

To accomplish the object, there is offered a portable knockdown house to be used for four seasons, which is made with a thin light plate where an aluminum plate is attached to both sides of a synthetic resin plate, for the floor, main walls and roof of the house, in order to reduce its weight
