Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underfloor storage system capable of taking out stored items such as books, documents, clothes, and other long objects stored in an underfloor space from an opening in a floor surface.

[0002]

2. Description of the Related Art As a system of this type, for example, there is a system in which a box-shaped container for storing documents or documents is taken in and out of an opening provided on a floor by an elevating device. Appears on the floor when in the raised position,
When it is in the lowered position, it is accommodated in the underfloor space.

[0003] Therefore, the container can be positioned below the floor surface, except when a book, a document, or the like is called, so that the apparent indoor space becomes larger by the space occupied by the container.

[0004] However, the system having the above configuration has the following problems. Since the storage device in which the storage items are stored protrudes from the floor surface, it is not possible to place an object such as a table in the room where the storage device is located, and the available space in the room is substantially reduced. It is narrow. Therefore,
In the case where many books and documents are stored under the floor, that is, in the case where books and documents are stored in a space having a large area under the floor, if the configuration of this system is adopted, the room inside The target space becomes very small. This has little use value. Since the container is a relatively small fixed box, a long one such as a golf bag or a ski cannot be used.

[0005] At present, it is difficult to obtain a large living space, and such an industry and a consumer are inexpensive, can store the contents without substantially reducing the indoor space, and can easily remove the contents. There is a long-awaited development of an underfloor storage system that can be easily installed in a relatively small space that can be easily accommodated in a relatively small space regardless of the shape of a long-sized container.

[0006]

SUMMARY OF THE INVENTION Therefore, according to the present invention, it is possible to store an object at a low cost without substantially narrowing the indoor space and to easily take out the container, and to obtain a long object. An object of the present invention is to provide an underfloor storage system that can be accommodated with ample space regardless of the size and can be easily installed in a relatively small space.
