Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a decorative board used as a top plate of a counter, etc., and a method for manufacturing the same.

(Prior art) Conventionally, this type of decorative laminate has a base material whose at least one side is an arcuate surface, and a covering material that covers this base material and whose surface is covered with a decorative sheet. If it is made of a material with little elastic deformation, such as wood, there will be a point along the arc surface,
It is known that the following curved surface processing is performed, that is, a large number of equally spaced grooves are formed on the back side of the above-mentioned location of the covering material, perpendicular to the bending direction of the covering material.

(Disadvantages of the Prior Art) The conventional decorative board has the following disadvantages. In other words, when the width of the opening of the groove becomes narrower than the width of the inner part, the curved part of the covering material is bent, but since the covering material is made of a material with little elastic deformation, it is not completely bent. Since it cannot be bent smoothly, that is, it is bent along the grooves, the folds appear as striped irregularities on the decorative sheet. In particular, when the decorative sheet is of a bright single color, this drawback becomes even more remarkable.

(Object of the Invention) The specific invention was made in order to eliminate the above-mentioned drawbacks, and it is an object of the present invention to provide a decorative board in which striped irregularities do not appear on the surface of the covering material.

The second invention aims to provide a method for manufacturing the decorative board.

(Example) First, the specific invention will be described based on an example shown in the drawings.

Decorative board 1 used as a top plate for counters, etc.
has a base material 4 whose front and rear surfaces 2 are arcuate surfaces 3, and the surface 2 of this base material 4 is covered with a covering material 5 described below. That is, the covering material 5 has a bent portion 6 that covers the arcuate surface 3, and a recess 7 of a predetermined depth is formed on the surface of the bent portion 6.
is formed, and in this recess 7, cork, synthetic resin,
An intervening material 8 made of a flexible material not limited to rubber or the like is attached, and the thickness of this intervening material 8 is set far from the depth of the recess 7, and is 0.5 to 3 mm.
The position is appropriate, but is not limited. On the other hand, a large number of comb-shaped grooves 9 are formed at equal intervals on the back side of the bent portion 6, perpendicular to the bending direction of the covering material 5, and the intervening material 8 and the covering material 5 are made of vinyl chloride or the like. It is covered with a decorative sheet 10.
With the above-described configuration, when the bent portion 6 of the covering material 5 is bent, the bent portion 6 is bent along the comb-shaped grooves 9, but the unevenness caused by the fold is due to the flexibility. It is absorbed by the intervening material 8.

Next, a second method of manufacturing the decorative board is described.
Examples of the invention will be described.

First, a recess 7 is formed on the surface of the bent portion 6 of the covering material 5, and the interposition material 8 is pasted onto the recess 7. Next, a decorative sheet 10 is placed on the intervening material 8 and the surface of the covering material 5.
Attach. After that, on the back of the bending part 6,
After forming the comb-like grooves 9 and performing such operations, the covering material 5 is attached to the surface 2 of the base material 4 with the bent portion 6 along the arcuate surface 3. In this way, a desired decorative board can be manufactured.

(Effects of the Invention) As described above, according to the specific invention, the irregularities of the folds caused by bending the covering material 5 are
Even if the decorative sheet 10
Even if it is bright and monochromatic, striped irregularities will not appear on it.

Moreover, according to the second invention, the decorative board can be easily manufactured.
