Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art A decorative veneer attached to the surface of a substrate is obtained by directly slicing natural wood, but with the depletion of natural wood in recent years, it becomes difficult and expensive to obtain what is called wood. Various veneer veneers are now being offered as alternatives.

Among them, for example, as a method for obtaining a veneer block-like decorative veneer, after gluing a plurality of natural wood blocks to each other to form a rectangular parallelepiped laminated wood, slicing in a direction orthogonal to the bonding surface. Then, a method of obtaining a laminated veneer one by one is known.

[0004]

In manufacturing such a laminated laminated veneer, a plurality of natural wood blocks having the same width are used, and these are arranged in a predetermined pattern and adhered to form a laminated lumber block. However, since all natural wood blocks of the same size were used, the lengthwise and widthwise joints of each veneer block in the laminated decorative veneer obtained by slicing the laminated wood block were all continuous on a straight line. As a result, it is poor in design and lacks in luxury.

For this reason, several types of natural wood blocks having different lengths are combined, for example, in the case of being used as a decorative sheet for flooring, they are combined into a rectangle of 1 × 6 shaku to form a laminated lumber block. Is commonly done.

However, when the number of types of natural wood blocks used in this way increases, there arises a problem that the process of manufacturing the natural wood blocks and the dimensional control become complicated, and conversely, the natural wood blocks are assembled using a small number of types. When assembling the lumber blocks, it becomes difficult to assemble the laminated decorative veneers obtained after slicing so that the longitudinal joints of the veneer blocks are located at different positions in each row.

[0007] Generally, in cutting out a natural wood block forming laminated wood, a timber of a constant angle is cut out from a natural wood log, and the natural wood block is cut out while avoiding defective portions such as knots or cracks of the timber. First, cut out the natural wood block size from the part where the longest natural wood block can be cut out, then cut out the second longest natural wood block size from the remaining material that could not cut out the longest veneer block, In the same manner, cut out the length of the natural wood block in order. In this way, the shortest natural wood block is finally cut out, and the material having a size smaller than that is discarded. Therefore, as the size of the natural wood block becomes longer, it becomes more difficult to supply a material capable of cutting out the natural wood block. If the natural wood block is shortened as a whole, the yield at the time of cutting will be improved and the supply of materials will be relatively easy, but it lacks the high-class feeling as a laminated veneer, and the veneer block will be joined in the length direction. Since the number of parts also increases, it is difficult to arrange them so that they do not match.

[0008]

DISCLOSURE OF THE INVENTION In order to solve the above problems of the prior art, the present invention uses a natural wood block of as few types as possible, and the length of the veneer block in the laminated decorative veneer obtained after slicing. To be completed as a result of earnest research for the purpose of providing a laminated decorative veneer with excellent design and high quality, in which the directional joints do not match in each row, preferably even on the extension line. It has come.

That is, according to the present invention, in a laminated decorative veneer formed into a rectangular shape by a set of a plurality of projecting plate blocks having the same width and different lengths of five types, the laminated decorative veneer has four rows in the width direction. Divided into at least two columns (B
1 and B2) are made up of 4 different types of 5 or 3 different types of 5 projecting block, and other rows (A1, A2) are different
It consists of four types of veneer blocks, and each of the other rows (A1, A2) has one veneer block () with the longest dimension among the five types of veneer blocks used. , In each of the at least two rows (B1, B2), one of the shortest-sized veneer block (5) among the five types of veneer block used and the length dimension of the shortest-sized veneer block. Is a laminated veneer having at least one veneer block (3) having a length dimension such that the sum of the two is equal to the length dimension of the veneer block (1) having the longest dimension. .

In a preferred embodiment, the other column (A
1, A2) are two outer rows in the width direction of the laminated decorative veneer, and the at least two rows (B1, B2) are two inner rows of the outer two rows (A1, A2).

In the inner two rows (B1, B2),
It is preferable that the veneer block (5) having the shortest dimension is arranged so as to face the opposing ends in the longitudinal direction of the laminated decorative veneer.

In the laminated decorative veneer of the present invention, preferably, the joint portions of the projecting plate blocks are arranged so as not to coincide with each other in each of the rows.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A laminated veneer according to an embodiment of the present invention will be described with reference to FIGS. This embodiment is used as a decorative veneer for a floor material as a laminated decorative veneer of a size of 1 × 6. As is apparent from FIG. 1, veneer blocks having the same width are arranged in four rows in the width direction. Among them, four projecting plate blocks are arranged in the uppermost row (A1) and the lowermost row (A2), and five projecting plate blocks are respectively arranged in the middle two rows (B1, B2).

The relationship between the lengths of the projecting plate blocks is as shown in FIGS. In FIG. 2, the reference numerals (1 to 5) attached to the projecting plate blocks indicate the order from the largest length dimension. That is, a veneer block having a total of 5 lengths is used in this laminated decorative veneer, and each of the uppermost row (A1) and the lowermost row (A2) has 4 blocks.
In this veneer block, one longest veneer block (1) among the veneer blocks used is arranged.
In addition, in the uppermost row (A1), one second longest projecting block (2) and two third longest projecting block (3) are arranged. The sum is the same as the total length of the laminated veneer. In the bottom row (A2), the longest veneer block (1) is one and the second longest veneer block (2) is 2.
One and the fourth longest veneer block (4) are arranged, and the sum of the lengths of these four veneer blocks corresponds to the total length of the laminated decorative veneer.

Among the five projecting block blocks in the middle two rows (B1, B2), the shortest projecting plate block (5) among the projecting plate blocks used is arranged. In addition, in the row (B1), the second longest veneer block (2) is one and the third longest veneer block (3) is three, so that a total of five veneer blocks are arranged, and the row (B2) In that case, there are a total of 5 veneer blocks, one with the second longest veneer block (2), one with the third longest veneer block (3) and one with the fourth longest veneer block (4). Arranged, the sum of these lengths corresponds to the total length of the laminated veneer.

Further, as shown in FIG. 3, among the above-mentioned five kinds of projecting plate blocks, the longest projecting plate block (1) has the shortest projecting plate block (5) and the third longest projecting plate block ( The length dimension of each of these projecting plate blocks is set so as to have a relationship equal to the sum of the lengths of 3).

In the middle row (B1), a total of five veneer blocks in which two veneer blocks (3) and (5) are incorporated in place of the longest veneer block (1) in the uppermost row (A1). Each joint is the top row (A
1) and the middle row (B2) is likewise replaced by two veneer blocks (3) instead of the longest veneer block (1) in the bottom row (A2). A total of five projecting plate blocks including (5) are installed so that the respective joints do not coincide with the bottom row (A2). Shortest veneer block (5)
In the middle row (B1) is at the left end of the drawing,
In 2), they are arranged at the right end in the figure.

[0018]

According to the present invention, the longest veneer block (1) that is difficult to supply is one row (A1) or two rows (A1, A).
It is only necessary to place one each in 2), and while it is relatively easy to supply materials when cutting out natural wood blocks,
It does not impair the high-class feeling as a laminated veneer.

In the other rows (B1, B2, B3), instead of the longest projecting block (1), the projecting block (3) and the shortest projecting block (5) are arranged at arbitrary positions. It becomes possible to use short natural wood blocks that have been conventionally discarded, and the yield in cutting out the natural wood blocks is greatly improved.

Further, since the joint portions of the projecting plate blocks in each row of the laminated decorative veneer are arranged so as not to coincide with each other on the extension line, the design is excellent.
