Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates primarily to the construction of wooden doors for homes.

[0002]

[Prior art]

 As shown in FIG. 2, a conventional interior wooden door is a veneer-bonded plywood board having a natural wood decorative veneer 21 affixed to the surface of a board 11, such as a solid board or plywood. Through the decorative edge material 71 cut from the material, the laminated material is used as the core material 41 and the decorative veneer 21 laminating board is adhered to the front and back surfaces of the frame body 61 having the flash structure, and then the front surface. By applying colored wiping paint to the entire surface, wooden doors with a three-dimensional effect and a high-class feeling that emphasized the grain were generally used.

[0003]

[Issues to be solved by the device]

 However, since the door with the above structure uses plenty of natural wood, it has become rare and expensive due to restrictions on logging in recent years, and it is not possible to stably supply materials. is there. On the other hand, in terms of quality, because of the natural wood, there was a problem that it was sensitive to the humidity difference in the atmosphere, and warpage and surface cracks were likely to occur.

Moreover, since the natural wood decorative veneer 21 is used as the surface decorative material, it is difficult to form the frame 61 around the door into a curved surface and to attach the frame 61, which results in an angular product. There were design restrictions. As a result, not only are they vulnerable to bumps from the corners during daily use, but there is also the risk of infants and the elderly hitting the corners of the door and getting injured by pinching their fingers.

The present invention aims to provide a wooden door that is safe in use, has a high degree of freedom in design, uses waste materials to reduce costs and resources, and has stable quality. .

[0006]

[Means for Solving the Problems]

 The door of the present invention is made to solve the above-mentioned problems, and includes a mirror plate having a decorative sheet adhered to both sides of a substrate, and a core material having a curved side surface at a longitudinal edge thereof. The frame is characterized in that a frame to which a flexible decorative sheet is continuously adhered is fixed to the side of the end plate with the curved side facing outward.

Hereinafter, the present invention will be described in detail with reference to the drawings of the embodiments.

FIG. 1 is a partial sectional view of a door of the present invention, 1 is a substrate, 2 is a decorative sheet, 3 is a mirror plate, 4 is a core material, 5 is a decorative sheet, and 6 is a frame.

A hard board, a medium-density fiberboard, a plywood, or the like is used for the substrate 1 used for the mirror plate 3, and the thickness is generally 3.0 to 20.0 mm. Since the surface smoothness of wood chipboard such as particle board and strand board is inferior to that of fiberboard, some surface treatment may be applied. In addition, it is preferable that the concave and convex portions are formed on the surface of the substrate 1 by cutting a gentle groove-shaped concave portion with a router or the like or by pressing with a die-pressing plate to improve the design.

Then, the decorative sheet 2 is attached to the surface of the substrate 1. The decorative sheet 2 is a flexible sheet such as a vinyl chloride resin sheet which is embossed on its surface and then colored and wiped, or a decorative sheet which is printed with ink on paper and then coated with a colored transparent paint. The material is preferably used and is adhered via a common adhesive. When the thickness of the substrate 1 is thin, the decorative sheet 2 may be attached to one side of the two substrates 1 and the other sides may be attached to each other. The decorative sheet 2 may be attached to both surfaces of the substrate 1. When the surface of the substrate 1 has irregularities, the irregularities are well fitted by pressure bonding with a vacuum press or the like.

On the other hand, as the frame body 6, a plywood board in which the entire core material 4 is integrated, or a board body 1 such as a fiber board laminated on the front and back surfaces is used. As the core material 4, a wood piece molding plate such as a particle board or a strand board or a single plate laminated material is used. As the substrate 1, a fiberboard such as a hardboard or a medium density fiberboard or a plywood is used. The fiber board used as the substrate 1 may be an insulation board having a low bending strength if the surface hardness is taken into consideration.

When forming the core material 4 of the frame body 6, a flash structure having a hollow portion formed therein may be used, or a so-called solid core structure filled with the core material 4 may be used.

Then, one side of the frame 6 is cut and formed into a curved surface by a molding machine or the like. There are various shapes such as a semi-circular shape, a fan shape, or chamfered corners, but about 15 to 40 mmR is suitable.

A flexible decorative sheet 5 is continuously attached to the core material 4. Similar to the end plate 3, the decorative sheet 5 is a flexible vinyl chloride resin sheet that has been embossed on the surface and then colored and wiped, or a decorative paper that is printed with ink on paper and then coated with a colored transparent paint. A sheet-like product having the above is preferably used, and a decorative sheet 5 that is seamless and continuous from one surface to the other surface of the core material 4 is adhered to the frame body 6 by a lapping machine or the like via an adhesive.

Then, the frame 6 is fixed around the end plate 3 via an adhesive or a nail to form a door.

[0016]

[Action]

 In this invention, the reason why the flexible decorative sheet is used is to form a curved surface around the door so that the decorative sheet can be attached so that it can be smoothly wrapped. When a sheet is used, the frame 6 can be given the appearance of a solid material, and there is no restriction in terms of design. Also, the reason why natural wood decorative veneer is not used for the surface material is to solve the problem that it is sensitive to temperature and humidity differences in the atmosphere, causing warping on the frame and cracking on the decorative surface. .

[0017]

【Example】

 After the wood grain pattern is printed on the paper on the surface of the medium density fiberboard 1 with a thickness of 5 mm, the decorative surface of the two decorative boards to which the decorative sheet 2 to which durability is given by applying a transparent coating is attached is applied. Layered toward the front surface side to form the end plate 3. Then, after stacking two 24 mm-thick party boards, a medium-density fiberboard of 5 mm thickness was attached to both sides of the board to form the base material 4, and one side of the board was cut into a semicircular shape. After printing a wood grain pattern on the same paper as above on the surface, a decorative sheet 5 to which durability was given by applying a transparent paint was integrally attached to the entire surface of the frame. Then, a frame 6 was fixed around the long side of the end plate 3 to obtain a door.

[0018]

[Effect of device]

 According to this invention, the frame body is formed by integrally bonding the core material whose outer side portion is formed into a curved shape so as to be wrapped with a flexible decorative sheet, so that the frame body is formed. It looks like it is made of solid wood, and it is not easily scratched by bumps on the corners of the door or fingers, and it is safe for infants and the elderly.

Further, since the fiberboard and the wood piece molding board using the waste material are used as the substrate and the core material, there is no fear of supply shortage due to resource depletion, and the quality is stable. Furthermore, since natural wood decorative veneer is not used as the surface material, it is sensitive to temperature and humidity differences in the atmosphere, and there are no problems such as warping of the frame or cracking of the decorative surface. .
