DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative laminated veneer obtained by gluing a plurality of natural wood blocks to form a laminated material and then slicing the laminated wood.

[0002]

2. Description of the Related Art A decorative veneer to be adhered to a substrate surface is obtained by directly slicing a natural precious wood, but with the depletion of natural wood in recent years, it is difficult and expensive to obtain what is called a precious wood. Various decorative veneers have been provided as substitutes.

Among them, for example, as a method for obtaining a parquet block-like decorative veneer, a plurality of natural wood blocks are bonded to each other to form a rectangular parallelepiped laminated material, and then sliced in a direction perpendicular to the bonding surface. There is known a method of obtaining laminated decorative veneers one by one.

[0004]

In the production of such a laminated veneer veneer, a plurality of natural wood blocks having the same width are used, arranged in a predetermined pattern and bonded to form a laminated wood block. However, if all natural wood blocks of the same dimensions were used, the joints in the length and width directions of each veneer block in a laminated veneer veneer obtained by slicing the glued laminated wood block would be continuous in a straight line. This results in poor design and lack of luxury.

[0005] For this reason, several types of natural wood blocks of different lengths are combined, and for example, when used as a decorative board for flooring, are combined to form a rectangle of 1 x 6 square size to form a laminated wood block. This is commonly done.

[0006] However, when the types of natural wood blocks used in this way increase, there arises a problem that the process of manufacturing the natural wood blocks and the dimensional control are complicated, and conversely, the assembly is performed using too few types of natural wood blocks. When assembling the material blocks, it is difficult to assemble the laminated veneer obtained after slicing so that the longitudinal joining portions of the veneer blocks are at different positions in each row.

In general, a natural wood block forming a laminated wood is cut out from a natural wood log by cutting a square wood having a fixed angle and cutting a natural wood block avoiding a defective portion such as a node or a crack of the square wood. First, cut out the natural wood block dimensions from the part where the longest natural wood block can be cut out, and then cut out the second longest natural wood block size from the remaining materials from which the longest veneer block could not be cut out, Similarly, the length of the natural wood block having a shorter length is sequentially cut out. In this way, the shortest natural wood block is finally cut out, and the material of smaller dimensions is discarded. For this reason, it becomes more difficult to supply a material from which the natural wood block can be cut out as the size of the natural wood block becomes longer. If the natural wood block is shortened as a whole, the yield at the time of cutting is improved and the supply of material is relatively easy, but it lacks the sense of quality as a laminated veneer, and the joining in the length direction of the veneer block Since the number of parts also increases, it is difficult to arrange them so that they do not match.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems of the prior art, the present invention uses the length of a veneer block in a decorative veneer obtained after slicing while using as few types of natural wood blocks as possible. The directional joints, preferably on the extension lines thereof, do not coincide in each row, and are completed as a result of intensive studies for the purpose of providing a decorative veneer veneer excellent in design and rich in luxury. It has been reached.

That is, according to the present invention, in a laminated veneer in which a plurality of veneer blocks are joined in the width direction and the length direction to form a rectangular shape, four types of veneer blocks having the same width and different lengths are used. Veneer block (1)-
(4) is used, and the sum of the lengths of the second longest veneer block (2) and the shortest veneer block (4) among the four types of veneer blocks is the third longest veneer block (3). It is set to be equal to twice the length, and the width direction of the laminated veneer is divided into four rows, and each row has one longest veneer block (1) and one second. 3 types including at least one long veneer block (2) 4
It is characterized by being composed of a plurality of veneer blocks.

FIG. 1 shows an example of the configuration of a laminated veneer veneer according to the present invention. In this configuration example, four types of veneer blocks having the same width and four different lengths are used, and all four rows divided in the width direction are three types of four veneer blocks including the longest veneer block (1). It consists of. The sum of the lengths of the second longest veneer block (2) and the fourth longest veneer block (4) of the four veneer blocks is twice the length of the third long veneer block (3). Each length dimension is set so as to be equal to. By setting such a length relationship, even if each row is composed of four kinds of veneer blocks of three types, by changing the arrangement order as appropriate, the longitudinal joining portion of each veneer block can be formed in each row. All of them do not match, and in each row, it is possible to arrange each veneer block so as to straddle two veneer blocks in an adjacent row.

[0021]

According to the present invention, the longest veneer block (1) which is difficult to supply can be used in a small number, and the material supply for cutting out the natural wood block is relatively easy. There is no loss of luxury as a board.

Further, since each veneer block in each row of the decorative veneer assembly is disposed so as to straddle two veneer blocks in another adjacent row, the design is excellent.
