Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a decorative panel, and more specifically, to provide a lightweight panel that has no defects such as blistering on the decorative surface.

Conventionally, a decorative panel as shown in FIG. 1 is produced by cutting off the edge of a plate-like base material 1 having a smooth surface s as shown in FIG. It was manufactured by laminating a decorative sheet 7. Therefore, unless the surfaces of slopes E ₁ , E ₂ , E ₃ , and E ₄ are polished and then the decorative sheet is laminated, the roughness of the cut surfaces will appear on the surface of the decorative sheet, reducing its commercial value. was severely damaged.

Also, base materials that cannot be or are difficult to polish cannot be used.

The present invention has been made to solve the above-mentioned drawbacks, and by combining a frame material with a special shape and a plate material with a smooth surface, both the upper surface and the slope surface can be polished without having to polish the surface of the slope surface. The present invention provides a decorative panel having a smooth finished surface.

A detailed explanation will be given below with reference to the drawings.

First, as shown in FIG. 4, a plate-like base material 1 having a smooth surface s is cut into a bar shape by cutting a cut surface A having an arbitrary angle with respect to the smooth surface s and a cut surface B parallel to this cut surface A. A member 2 is cut out, and then a plate-shaped portion 3 is cut out from the member by a cut plane C parallel to the cut plane A and the cut plane B, and a cut plane D perpendicular to the cut plane C, as shown by diagonal lines. Get the parts. Furthermore, both longitudinal ends of the member are cut diagonally inward at an arbitrary angle to form a frame material 4 as shown in FIG.
get. This arbitrary angle is generally 45 degrees, but as described below, it can be within a range greater than 0 degrees and less than 90 degrees (although in reality, angles close to 0 degrees or 90 degrees cannot be applied). Can be selected arbitrarily.

Next, as shown in Fig. 6, the cut surface C of the frame material 4 is
Next, attach a plate material 5 with a smooth surface so that the end of one side of the plate material 5 is in contact with the cut surface D, and then attach the remaining three sides of the plate material 5 in the same manner to the other three frame materials. 4
A panel 6 as shown in FIG. 7 is obtained by pasting it on the cut surface C of the panel.

FIG. 7 is a so-called bottom view of the panel 6 seen from the back side (non-decorative side), and the angle at which both ends of the frame material 4 used in the panel of FIG. 7 are cut off is 45 degrees.

As mentioned above, the cutting angle can be arbitrarily selected within the range greater than 0 degrees and less than 90 degrees, so as shown in FIGS. A panel having a square or rectangular bottom surface can also be obtained by combining a pair of frame members 4' and a pair of frame members 4'' having a cutting angle that is complementary to the cutting angle.

In addition, if both ends of the frame material are cut diagonally at different angles, as shown in Figures 11, 12, and 13, two adjacent corners of the panel will be cut after being assembled into a panel. By combining so that the sum of the angles is 180 degrees, a panel with a parallel rectangular base can be obtained. Of course, squares and rectangles also fall within this range of parallel quadrilaterals.

The panels shown in Figures 7 to 10 each use two pairs of frame materials of the same shape, but the cutting angles at both ends are different, as shown in Figures 11 to 13. When using frame materials, all four frames are assembled with irregularly shaped frame materials. Two are of the same shape, and the other two are made of irregularly shaped frames. Three frames are of the same shape and only one frame is of an irregular shape. Various combinations are possible.

Next, as shown in FIG. 14, a decorative sheet 7 is laminated to the entire smooth surface of the panel 6 to obtain a decorative panel.

The decorative sheet 7 may be attached not only to the front surface of the panel 6 but also to the back surface thereof.

As shown in FIG. 16, the frame material 4 has its widthwise end, that is, the intersection between the smooth surface S and the cut surface A, and the intersection between the back surface of the plate-shaped base material 1 and the cut surface C. It is also possible to cut it into any shape. For example, a decorative panel using the frame material 4- shown in a of FIG. 16 and a decorative panel using the frame material 4- shown in e of FIG. If it is pasted on the decorative surface of the paper, the boundary part can be made into an insert structure.

As the plate-like base material 1 having a smooth surface s, any material with a smooth surface can be used, such as hardboard, insulation board, particle board, plywood, gypsum board, inorganic board such as slate, etc. It is also very advantageous in terms of cost, since it is possible to use offcuts with dimensions large enough to cut out frame materials without using a plate-like base material of the same size as the particularly required decorative panel.

As the plate material 5 having a smooth surface, the plate-shaped base material 1
You can use what is available as .

Decorative sheets include wood grain patterns, abstract patterns,
Other paper with arbitrary patterns, synthetic resin sheets,
Fabrics, nonwoven fabrics, and combinations of two or more thereof can be used.

The decorative panel of the present invention manufactured as described above can be used as a single decorative panel or in a state where a plurality of decorative panels are pasted on the surface of another base material, such as walls, ceilings, etc.
Applied to other decorative surfaces.

The decorative panel manufactured by the method of the present invention has the following effects.

Since the decorative panel is constructed so that the entire surface is smooth, the decorative surface is finished smoothly.

It is lightweight because it has a panel structure with many open spaces.

It is advantageous in terms of cost because scraps can be used as the frame material.

Because it is lightweight, it can be constructed into panels that are thicker than conventional panels.
