Abstract

PROBLEM TO BE SOLVED: To provide a book shelf which hinders books from tipping over when the books are put on a book case or on the book shelf. SOLUTION: Each bottom plate of the book shelf is made as a convex part arched in shape, in the combination of planes shaped in a figure of a dog leg shape or in trapezoid or in the combination of planes and arches in shape.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a bookshelf in which a flat bottom plate is mounted on a vertical side plate in a horizontal or non-horizontal state with respect to the side plate. The present invention relates to a bookshelf having a convex portion provided on a bottom plate portion of the bookshelf.

[0002]

2. Description of the Related Art Conventionally, bookcases and bookshelves have been made of straight surfaces such as vertical surfaces and horizontal surfaces.

[0003]

This has the following disadvantages. In the past, when placing a book on a bookshelf or bookcase, the book would often fall down and be troubled if the book was not laid flat. The present invention has been made to eliminate the above disadvantages.

[0004]

Means for Solving the Problems A side plate of a bookshelf is provided with an upward opening (flowering shape) angle or vertical, and a convex portion is provided on a bottom plate. The shape of the projection is as follows. This is the shape of the outer periphery of an arc (hereinafter referred to as an arch shape) in which the angle between two straight lines extending from the center of the circle toward the circumference can be set to an inner angle in the range of 150 degrees to 1 degree. In addition, this is a case where a plane is combined with a U-shaped or trapezoidal shape. Also, this is a case where a plane and an arch shape are combined. The present invention is a bookshelf configured as described above. There is no need to stand the book diagonally,
You can just put the books and documents. Further, the present invention provides a bookshelf in which the bottom plate is hardly deformed by the weight of the book when the convex portion has an arch shape and when the flat surface has a concave shape.

[0005]

Embodiments of the present invention will be described below. The side plate of the bookshelf is opened upward (flowering shape) at an angle or kept vertical, and the shape of the convex portion of the bottom plate is an arch shape. Alternatively, the shape is a combination of a partially arched shape and a plane. Alternatively, a shape obtained by combining only a flat surface into a U-shape or trapezoid is adopted. The present invention has the above-described structure. When this is used, a book or a data file may be left as it is without having to hang it slightly obliquely as in the past. Also, in the case of an arch shape or a U-shape, the bottom plate is particularly difficult to bend. Examples of making the present invention include a case where the bottom plate and the side plate are integrated to form a bookshelf by metal pressing or plastic molding, or a case where the bottom plate and the side plate are separately formed by metal pressing or plastic molding, etc. It is. When wood is used as the material, the bottom plate may be bent into an arch shape, the wood may be cut out and formed into a convex shape, or a plurality of materials may be joined to form a plywood.

[0006]

According to the present invention, since the bookshelf is raised to a convex shape such as an arch shape or a U-shape, it is not necessary to lay the book or the like a little obliquely. Especially in the case of an arch shape, when a book or data file is placed, it is easy to create a gap as you go to the top of the book, point your finger in, and put out the booklet. In addition, when the convex part of the bottom plate is particularly in the shape of an arch and when only the flat plate is combined in a U-shape, the strength increases in the vertical direction, so the thickness of the bottom plate can be reduced, making the bookshelf even smaller than before. This makes it easier to reach books, making it possible to create a light and sturdy bookshelf. In addition, the shape of the convex portion such as the arch shape of the bottom plate can provide the possibility of bookshelves of various designs.
