The present invention relates to a bookcase, and more specifically, to form a WM groove having a predetermined inclination angle in the middle of the inner surface after the standardized and cut 3mm or less, MDF board of the shape of a sheet attached to the surface After forming a plurality of sets in the longitudinal direction and applying an adhesive on the upper surface, by placing the core material and bending, and finishing the panel for the bookshelf, the more beautiful bookshelf can be mass-produced, it is possible to provide a cheap price, as well as the assembly work It is about a bookshelf which is durable by building a firmness.

In general, a bookcase is a kind of storage furniture, commonly referred to as a library or a bookshelf, which is used for organizing and storing various books on each floor divided into a plurality of compartments while standing on one wall of an interior.

In the case of the plate-like materials constituting the bookshelf, a wooden bookshelf is used that forms a solid wood into a plate, fabricates a surface, and assembles it, and has various advantages such as solid advantages, long life, and quality maintenance. There is, but recently, the supply and demand of solid wood becomes cheaper and is used artificial wood that can obtain the texture of the wood.

In order to solve the shortcomings of the above-mentioned wood, conventionally, the bookshelf is made of artificial wood such as MDF. To withstand the loads of books stored on the bookshelf, the MDF board maintains a thickness of at least 12 to 35 mm. The texture of the wood is obtained by cutting the sheet and attaching sheet paper made of PVC to the surface.

However, the above-mentioned conventional technology does not contribute much to cost reduction because MDF maintains a certain thickness, and synthetic resin sheet paper is used, and when incinerated at disposal, harmful substances such as dioxin are generated, and thus, environmental pollution such as air pollution is caused. It is also a major cause.

In addition, as a way to reduce costs by reducing the thickness of the MDF, after forming the frame with core materials using wood, etc., the technology of attaching the flat plate MDF to the upper and lower surfaces of the frame is disclosed, but this is the core material The production work of the frame using the necessity becomes necessary, and the labor time increases, and when the bookcase is assembled, the frame itself becomes an obstacle, so it is not desired to be assembled, which is contrary to the cost reduction, and it is inconvenient when moving a lot of loads, especially MFC The environmental pollution problem is still not solved because a lot of harmful substances are generated when the synthetic resin sheet attached to the surface is incinerated.

While maintaining a light weight, there is an urgent need for supplying low-priced bookshelves without generating environmental pollutants.

Here, sheet paper attached to the surface of furniture refers to a finishing material that protects the raw materials and expresses the exterior in various colors and textures, and is particularly used as a material for decorating interior materials, furniture, and desks. .

The decorative sheet is manufactured by a method of painting or laminating, and the laminated film may be divided into PVC decorative sheet, paper, melamine sheet and the like according to the material used.

Of these, PVC decorative sheets, which are commonly used, are generally used for overlay for flat upper part of furniture or construction materials (Medium Density Fiberboard) or PB (Particle Board). Wrapping is used for areas that require curved processing, such as sash or molding parts.

In recent years, the use of PVC decorative sheets having a textured appearance in addition to the decorative sheets of various wood pattern products has been increasing, but such PVC sheets are not only difficult to express the desired pattern, but also have low hardness, which may cause scratches on the surface or daily life. If it is contaminated with contaminants, it is not easy to remove it, which has the disadvantage of poor durability. In addition, it will not only be difficult to increase the chromaticity, but also cause a lot of cost increase.

Even more serious problem is that it emits a large amount of toxic gas during incineration or fire, so it is fatal to human body and it is classified as environmentally harmful substance which is regulated internationally.

Indoor air pollution prevention legislation has been enacted not only internationally but also in Korea, and symptoms such as headaches and respiratory diseases caused by chemicals such as formaldehyde and organic solvents emitted from building materials and finishing materials are caused by sick house syndrome. Sick house syndrome, a disease called chemical hypersensitivity, is a major social problem.

Paper sheet, commonly referred to as shape paper, is a paper sheet attached to the surface of the equipment, which means that the printed paper surface is coated in consideration of problems such as durability and abrasion resistance, and is commonly used to decorate the outer surface of furniture. Although used, structural materials such as bookcases that withstand loads were not used due to their poor durability.

Accordingly, the present invention has been researched and created to solve the disadvantages of the conventional bookcase as described above, the purpose of providing this is to cut the standardized MDF board of 3mm or less, thin plate shape on the surface is attached After that, a plurality of sets of W-shaped grooves having a predetermined inclination angle in the longitudinal direction are formed in the longitudinal direction, and an adhesive is applied to the upper surface thereof, and then the core material is placed, bent and tucked to complete the bookcase panel. In addition to being able to mass-produce the low cost, as well as to build a robust assembly work to provide a durable bookshelf.

In order to achieve the above object, the present invention standardizes and cuts 3 mm or less, MDF board having a sheet shape on the surface thereof, and then cuts the W-shaped grooves each of which maintains 22.5 ° in the middle of the inner surface. After forming a plurality of tanks in the direction and applying the adhesive, it was possible to fold the W-shaped grooves to be bonded to each other to form a tapered surface without bending the outer bent in a right angle to prevent the shape paper from being torn or loosened and deformed.

Hereinafter, the present invention will be described in detail to achieve the above object.

That is, the bookshelf of the present invention is shown in the accompanying drawings, Figures 1 to 3,

Standardized and cut 3mm or less, MDF board (1) of the form of a sheet attached to the surface of the paper,

W-shaped grooves 2 having an inclination angle of 22.5 ° are formed in the longitudinal direction in the middle of the inner surface of the board 1, and a plurality of sets are formed in the longitudinal direction.

After the adhesive is applied to the upper surface of the board (1), the core material (3) and the core material (3 ') is disposed on one end of the W-shaped groove (2) formed on one side of the one board (1) In the middle part, the styrofoam 4 is fixed,

By bending the other side of the board 1 and targeting one side, the bookcase panel 5 is completed.

By providing a plurality of panels 5 and assembling them to form a bookcase (6),

When the inclined surface of each of the W-shaped grooves 2 are assembled by bending assembling of the board 1, the side surface and the upper and lower surfaces of the core material 3 positioned on one side are firmly abutted when they are bent and formed inside at right angles. A tapered surface 51 is formed on the lower edge side of the outer side, and the strength is reinforced by the joining surface without damaging the paper of the outer surface.

Reference numeral 11 indicates a cut line.

Referring to the operation of the present invention made of such a structure as follows.

First, in the process of cutting the board (1) in consideration of the side plate and the inner support plate is bent and used, after standardizing each of the cut,

In addition, after applying the adhesive, the core material (3), (3 ') and the styrofoam (4) corresponding to the spaced space of the W-shaped groove (2) formed in the intermediate portion can be provided only by standardizing to match it.

After standardization of such assembly parts, one side of the core material 3 is disposed at one end of the W-shaped groove 2 positioned in the middle of the board 1 so that the core material 3 'is disposed on the outside thereof. Arranged to coincide with the tip, the styrofoam (4) is placed in the middle portion, and the state is fixed by the adhesive applied to the main surface.

By bending this, one side and each upper surface of the core material 3 are maintained by assembling and fixing the board 1 located on the other side about the W-shaped groove 20.

At this time, since the W-shaped grooves 2 maintain 22.5 °, respectively, the inclined surfaces thereof are assembled and assembled to each other, and the sides and upper and lower surfaces of the core material 3 located on one side are firmly abutted at the same time. Since the tapered surface 51 is naturally formed on the outer upper and lower corners, the assembling work of the unit is completed without damaging the shape paper of the outer surface.

In particular, the tapered surface 51 formed at the time of assembling and bonding of the single product is completed as a bookcase 6 to eliminate the sharpness during use to secure the safety of the user and at the same time to obtain the external beauty, the styrofoam interposed therein ( 4) prevents deformation of the board while keeping the space at a constant distance, thereby reducing the weight of the bookcase 6 itself, thereby enabling the dissemination of lightweight bookcases.

According to the present invention, after standardizing and cutting the MDF board having a shape of 3 mm or less and a thin plate on the surface, a plurality of sets of W-shaped grooves having a predetermined inclination angle in the middle of the inner surface thereof are formed in the longitudinal direction. After applying the adhesive on the upper surface, placing the core material is bent, and finished to complete the bookcase panel by making the beautiful bookcases can be mass-produced, it is possible to provide a cheap price, as well as to build the robustness of assembly work It is obvious that this is a very beneficial design that can provide this superior and lighter bookcase.
