Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wood door, and more particularly to a wood door using a vertically long rectangular wood fiber board as a base material.

[0002]

2. Description of the Related Art A moving door such as a tall cabinet or a closet is required to be lightweight in consideration of operability, and therefore, a wood fiberboard such as MDF is often used as a base material. In particular, a folding door such as a closet door has a relatively narrow lateral width (for example, about 300 to 400 mm). There is no particular problem if the height of the door is low, but the height is 1600 to 2
If the length is about 400 mm, if the vertically long rectangular wood fiber board is used as it is, the rigidity (independence) with respect to bending may be insufficient and warping may occur due to its own weight.
For this reason, another member is attached along the long side to increase the wall thickness, or a vertical frame is attached to prevent warpage.

[0003]

By taking the above-mentioned means, it is possible to prevent the wooden door using the vertically long rectangular wood fiber board as the base material from warping. However, preparing another member and pasting it,
Alternatively, the work of separately forming a vertical frame and assembling it to the base material side is complicated and complicated, which is one of the causes of increasing the manufacturing cost.

The present invention has been made in view of the above circumstances, and in a wood door using a wood fiber board having a vertically long rectangular shape as a base material, without using a separate member,
An object of the present invention is to provide a wooden door in which the rigidity of the entire body is improved by only performing simple processing, and thereby warpage can be avoided even when the door is tall.

[0005]

The wooden door according to the present invention comprises:
The base material is a wood fiber board having a vertically long rectangular shape, and a side edge portion along at least one long side of the wood fiber board is a kerf formed along one long side on one surface side of the wood fiber board. It is fixed in a bent state by utilizing, so that a rising portion having a substantially L-shaped cross section is formed on at least one end face in the longitudinal direction.

In the present invention, the wood fiberboard used as the base material is preferably MDF because of its good surface properties and machinability, but it is not limited to this and may be HDF. The wood fiberboard as the base material may be one, or may be one in which multiple layers are adhered and laminated.

According to the present invention, the wood fiber board as the base material is bent along the long side so that the side edge region of the required width is formed by utilizing the kerf formed by, for example, V-cut processing on the one surface side. As a result, a rising portion having a substantially L-shaped cross section is formed along one or both of the side edges in the longitudinal direction. The rising portion improves rigidity against bending as compared with the case where the wood fiber board as the base material is simply a flat plate, and suppresses warpage due to its own weight. The height of the rising portion is appropriately selected, but may be determined by experiment or in consideration of the material, thickness, height, etc. of the wood fiber board to be used.

In the above base material, in the state where the kerf is formed, the high-density surface layer on the other surface of the wood fiber board which is the base material remains as it is, and the side edge region is bent using the kerf. It is easy to fix it with an adhesive or the like and use it as the rising portion. In addition, the surface of the base material after the rising portion is formed is covered with the high-density surface layer on the other surface, so that a wooden door having high surface smoothness can be obtained as it is. If necessary, the base material may be subjected to molding processing such as chamfering, and surface decorative materials such as synthetic resin sheets, veneer sheets, decorative paper, etc. may be wrapped to create a wooden door with a higher design. Of course, it is also good.

BEST MODE FOR CARRYING OUT THE INVENTION One embodiment of a wooden door according to the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a state in which two kerfs 12a and 12b having a V-shaped cross section are cut and formed in 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. Shows. The length (height) H of the wood fiberboard 11 is the same as the height h of the wooden door 10 to be manufactured, but the width W thereof is a predetermined width larger than the width b of the wooden door 10 to be manufactured. However, in the illustrated case, the width is widened to the left and right respectively.

The two kerfs 12a, 1 having the V-shaped cross section.
2b, from the one surface side of the wood fiber board 11 to the other surface side, the position of the top 13 is located at a position a distance a inward from the left and right side edges in the longitudinal direction, respectively.
It is formed parallel to the side in the longitudinal direction. At the time of cutting, at least the high-density surface layer 14 of the wood fiber board 11 is left between the tops 13 of the cut grooves 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 it may be narrower or wider than 90 degrees depending on the usage of the wooden door 10. Further, in the figure, two kerfs 12a and 12b are formed along the left and right long sides, but depending on the usage of the wooden door 10, only one of the kerfs may be formed. May be.

Next, an adhesive is applied to the V-cut surfaces of the cut grooves 12a and 12b, and the cut grooves 12a and 12b are used to bend the region having the width a from the side edge to bond the V-cut surfaces to each other. Wait for the adhesive to cure. By curing the adhesive,
The wooden door 10 shown in FIG. 2 is completed.

As shown in the figure, in the wooden door 10,
The bent side edge region forms a rising portion 20 having a height a and a substantially L-shaped cross section. Due to the presence of the rising portion 20, the strength against bending (bending resistance) is remarkably improved and the wooden door 10 is warped due to its own weight as compared with a flat plate-shaped wooden door having a horizontal width b. The occurrence of is greatly suppressed.

Further, the wooden door 10 is covered with a high-density surface layer 14 on the surface and side surfaces thereof, and a wooden door having high surface smoothness can be obtained. If necessary, a required molding process such as a chamfering process is performed, or as shown by phantom lines in FIG. 2, an appropriate surface decorative material 30 such as a veneer or a decorative paper is lapped on the surface or side surface. You may do it. This makes it possible to obtain a wooden door with a higher design.
