Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wood door, and more particularly to a wood door using a wood fiber board having a vertically long rectangular shape as a base material.
[0002]
[Prior art]
Mobile doors such as tall cabinets and closets are required to be lightweight in consideration of operability, and therefore, a wood fiber board such as MDF is often used as a base material. In particular, the folding type such as a closet door has a relatively narrow width (for example, about 300 to 400 mm). There is no particular problem when the height of the door is low, but when the height is about 1600 to 2400 mm, if the wood fiber board having a vertically long rectangular shape is used as it is, rigidity (self-supporting) against bending is insufficient. Warpage may occur due to its own weight. For this purpose, another member is attached along the long side to increase the thickness, or a vertical hook is attached to prevent warping.
[0003]
[Problems to be solved by the invention]
By taking the above-mentioned means, it is possible to prevent the warp from occurring in the wood door using the vertically long rectangular wood fiber board as the base material. However, the work of preparing a separate member and attaching it, or the work of separately making a vertical gutter and assembling it on the substrate side are complicated and complicated, which contributes to an increase in manufacturing cost.
[0004]
The present invention has been made in view of the circumstances as described above, and in a wooden door using a wood fiber board that is a vertically long rectangular shape as a base material, only simple processing is performed without using a separate member. An object of the present invention is to provide a wooden door that can improve the overall rigidity, thereby avoiding the occurrence of warping even when it is tall.
[0005]
[Means for Solving the Problems]
The wood door according to the present invention is a wood fiber board whose base material is a vertically-long rectangular shape, and a side edge portion along at least one long side of the wood fiber board has a long side on one side of the wood fiber board. It is fixed in a state where it is bent using a kerf formed along it, so that a rising portion having a substantially L-shaped cross section is formed on at least one longitudinal end face.
[0006]
In the present invention, the wood fiberboard used as the base material is preferably MDF for reasons such as good surface properties and good machinability, but is not limited thereto, and may be HDF or the like. The wood fiber board as the substrate may be a single sheet or may be laminated and laminated in multiple layers.
[0007]
According to the present invention, a wood fiberboard as a base material has a side edge region of a required width bent along a long side by using, for example, a cut groove formed on one surface side by V-cut processing, Thus, a rising portion having a substantially L-shaped cross section is formed along one or both of the sides in the longitudinal direction. By this rising portion, the rigidity against bending is improved as compared with the case where the wood fiber board as the base material is simply a flat plate, and the occurrence of warpage due to its own weight is suppressed. The level of the height of the rising portion is appropriately selected, but may be determined by experiment or considering the material, thickness, height, and the like of the wood fiber board to be used.
[0008]
In the above-mentioned base material, in the state where the kerf is inserted, the high-density surface layer on the other surface of the wood fiber board as the base material remains as it is, and the side edge region is bent using the kerf, and the adhesive It is easy to work with the rising part by fixing it with the like. Further, the surface of the base material after the rising portion is formed is covered with the high-density surface layer on the other surface, and a wooden door with high surface smoothness can be obtained as it is. When necessary, the base material is molded by chamfering or other decorative materials such as synthetic resin sheets, veneer sheets, decorative paper, etc. Of course it is good.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, one embodiment of a wooden door according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a state in which two cut grooves 12a and 12b having a V-shaped cross section are cut and formed on a wood fiber board 11 such as MDF as a base material in order to manufacture a wood door 10 according to the present invention. Show. The length (height) H of the wood fiber board 11 is the same as the height h of the wood door 10 to be manufactured, but its width W is a predetermined width than the width b of the wood door 10 to be manufactured. However, in the figure, it is widened by a width a on each side.
[0010]
The two cut grooves 12a and 12b having a V-shaped cross section are located at distances from the one side of the wood fiber board 11 toward the other side, and the position of the apex 13 is inward from the left and right sides in the longitudinal direction. It is formed in parallel with the side in the longitudinal direction so that only a is included. In the cutting process, at least the high-density surface layer 14 of the wood fiber board 11 is left between the tops 13 of the kerfs 12a and 12b and the other surface side of the wood fiber board 11. The opening angle of the kerfs 12a and 12b having a V-shaped cross section is preferably 90 degrees, but may be narrower or wider than 90 degrees depending on how the wooden door 10 is used. In the figure, the two kerfs 12a and 12b are formed along the left and right long sides. However, depending on the usage of the wooden door 10, the kerfs may be formed only in one of them. May be.
[0011]
Next, an adhesive is applied to the V-cut surfaces of the kerfs 12a and 12b. Using the kerfs 12a and 12b, the region of the width a is bent from the side edges to bond the V-cut surfaces to each other. Wait for curing. The wood door 10 shown in FIG. 2 is completed by curing the adhesive.
[0012]
As shown in the figure, in the wooden door 10, a rising portion 20 having a substantially a L-shaped cross section having a height a is formed by the bent side edge region. Due to the presence of the rising portion 20, the strength against bending (bending resistance) is remarkably improved while the width is the same as that of a flat wooden door having a width b, and the wooden door 10 is warped by its own weight. The occurrence of is greatly suppressed.
[0013]
Moreover, the said wooden door 10 is covered by the surface layer 14 with a high surface and a side surface, and a wooden door with high surface smoothness is obtained. If necessary, a required molding process such as chamfering is performed, or an appropriate surface decorative material 30 such as a veneer or a decorative paper is wrapped on the surface or side as shown by a virtual line in FIG. You may do it. Thereby, it is possible to obtain a wooden door with higher design.
[0014]
