Abstract

PROBLEM TO BE SOLVED: To prevent a corner of a decorative plate curved by chamfering corners of edge materials from being discontinuously observed by cutting a rectangular decorative plate parallel to previously mounted two side faces of end or butt end of the plate, removing decorative sheets mounted on the two side faces, and mounting the edge materials having a continuous design pattern present in its thickness direction at the removed two side faces. SOLUTION: Decorative sheets S are mounted from parallel two side faces of one of ends or butt ends of a rectangular decorative plate over surfaces by a soft forming inlay(SF) method. Similarly, the sheets S are mounted from parallel two side faces of the other of the ends or but ends of the plate by the SF method. Then, it is cut in parallel with the previously cut two side faces, and the sheets mounted on the two side faces are completely removed. Thereafter, edge materials E each having a continuous pattern having a large thickness and present in its thickness direction are mounted on the cut two side faces, and corners of the materials E are eventually chamfered. The sheet S mounted by the SF method are materials which can be easily bent and deformed by heating.

る。[0003] In the case of a shelf board or the like inside a furniture storage unit, since the problems relating to the beauty and safety of the corners do not matter so much, the border is applied to the edge of the wooden edge and the edge of the wooden board. It is sufficient to simply cut the plate vertically and apply a flat thin edge material to the surface, and to chamfer the corners. Corners such as doors and table tops also need to be rounded by increasing the chamfers of the corners because aesthetics and safety are also important.

一に貼りつける方法である。[0005] Therefore, a method as shown in FIG. 5 is usually performed as a method for not increasing the cost so much. That is, a method is employed in which a decorative sheet on which a natural wood pattern or a monochromatic color is printed is attached from the side to the surface by a soft forming inlay method, and the corners are curved. The soft forming inlay method is a method in which, while bending a decorative sheet by heat, the decorative sheet is adhered from the side to the surface of the decorative plate with an adhesive so that the corners are at a right angle or the curved surface is provided, and is flush with the surface. .

Is attached by two steps of attaching. This process will be described in detail. First, as shown in FIG. 2, a decorative sheet S is attached from the wood end face to the surface of the decorative board, and then cut by the thickness of the decorative sheet S from the cut end to the surface. Chip (FIG. 3). Subsequently, the decorative sheet S is applied from the cut-out edge to the surface (FIG. 4). Finally, the C1, C2, and C3 surfaces are chamfered so that the corners become continuous curved surfaces (FIG. 5).

が、図７のように局部的に現れているから外観を損ねる
のである。Since FIGS. 1 to 5 are schematically drawn for easy understanding of the whole invention, practical dimensions and detailed portions are omitted, such as omitting the curved surfaces of the corners of the base material. However, if the cross section near the C1 plane in FIG. 5 is drawn in detail according to practical dimensions, a cross sectional structure as shown in FIG. 7 is obtained. FIG.
As is clear from FIG. 4, the cross section D of the decorative sheet appears at the chamfered portion. The cross section D becomes more prominent as the radius of curvature of the chamfer increases and as the thickness of the decorative sheet increases. If the cross section of the decorative sheet S appears continuously over the entire length of the chamfered portion, it is not so unsightly, but since it appears locally as shown in FIG. 7, the appearance is impaired.

ある。When the pattern of the decorative sheet is monocolor and the inside is the same color, it is not so noticeable, but not only an adhesive layer appears at the boundary with the curved surface portion C, but the chamfering of this portion is Since it is usually performed by a machine such as a sander or manual work, there is a difference in the surface smoothness and gloss etc. from the curved surface portion C where the surface of the decorative sheet appears as it is, and although there is a degree of difference, It does not change.

え、やはり美観面で見苦しい。When the pattern of the decorative sheet is a wood grain pattern and printing is performed only on the surface of the sheet, the ground color of the base material of the decorative sheet S appears on the C1 side, which is even more unsightly. In addition, even if a decorative sheet having a structure like a so-called Kintaro candy, in which a continuous pattern appears even if it is cut in the thickness direction like a veneer veneer made of natural wood, in FIG. Since the directions of the grain cross at the boundary with the cross section D of the sheet, the portion of D gives a feeling of being peeled off, which is also unsightly in aesthetic appearance.

が高くなる。BEST MODE FOR CARRYING OUT THE INVENTION In the practice of the present invention, the base material of a wooden decorative board is a plywood, LVL, fiber board, particle board, etc., if it is a wooden flat base material used for construction, furniture, and housing equipment. Anything is fine. The decorative sheet before applying the decorative sheet S and the edge material E is a decorative sheet or a natural precious wood veneer on at least one surface of the base material, while the other surface is the base material. May be. The decorative sheet S applied by the soft forming inlay method is a material that can be easily bent and deformed by heating. For example, soft and thin vinyl chloride can be easily bent and deformed without heating, but has a low surface hardness and is easily damaged. If hard vinyl chloride is thick, bending deformation takes a long time and work efficiency is low. Moreover, the thicker, the higher the cost.

化粧シートを使用する必要はない。Therefore, the decorative sheet S used in the present invention
May be selected based on the performance required for the use of the decorative board manufactured by the method of the present invention, and there is no need to particularly limit various properties such as sheet thickness and flexibility. However, since the object of the present invention is to provide a curved surface to a corner by a low-cost method, it is not necessary to use a decorative sheet that is thicker than necessary.

も曲率半径プラス０．５ｍｍまでが適当である。Next, as for the edging material E used in the present invention, the edging material E is applied to a curved surface portion at the boundary between the wood end surface or the lip surface and the surface and a chamfered portion at the boundary between the wood end surface and the lip surface. Since a cross section appears, the edge material E needs to have the same color and pattern appearing continuously in the thickness direction from the surface to the inside like Kintaro candy. As such an edge material, those made of synthetic resin and having a wood grain pattern or a monocolor are commercially available. In addition, the thickness of the edge material E needs to be a thickness corresponding to the radius of curvature of the curved surface provided at the corner. Not only is it economically wasteful to use a thicker one, but also the border line with the surface decorative sheet cuts into the decorative plate surface side by the excess thickness, so even if it is thicker, the radius of curvature plus 0.5 mm Appropriate.

る場合がある。As described above, since the edge material having a thickness corresponding to the radius of curvature of the rounded corner is required, the case where the radius of curvature is too large or the area of the side surface on which the edge material is to be applied is smaller than the area of the surface of the decorative plate. On the other hand, if it is larger than usual, the cost may be higher.

合は、表面と同様に考えればよい。In general, the longer side is referred to as a wood end, and the shorter side is referred to as a kiguchi. In the explanatory view of the present invention, the side where the rim is attached is the wood end face, but the shorter the rim is attached, the cost is cheaper, so it is normal to attach the rim to the tip end. . In short, it is only necessary to decide on which side the edge material is to be attached in consideration of design problems and costs. Although the figure does not show the details of the lower part of the decorative plate or the corners of the rear surface, when the same cosmetic is required on the rear surface depending on the application, it may be considered in the same manner as the front surface.

In this portion, the color tone and luster are different from other portions of the corner portion, and the pattern is not continuous, so that the aesthetic appearance of the decorative plate is impaired. The present invention is an improvement over the above-mentioned disadvantages of the prior art.
