In general, uneven wood decorative boards are used as constituent materials for doors and the like. This type of uneven wood decorative board is
As shown in FIG. 1, a feather core 2 is placed on a back plate 1 by applying an adhesive, and a core material 3 is also placed thereon. It is constructed by applying adhesive and overlapping them, and arranging edge materials 5 at the ends of the front plate 4 and the back plate 1. The uneven wood decorative board having such a structure has a problem in that when the thickness of the core material 3 and the feather core 2 are different, the surface board 4 does not adhere well to the core material 3 and the feather core 2, resulting in poor adhesion.
〔発明の目的〕
この発明は接着不良の生じない凹凸木質化粧板
の製造をその目的とするものである。[Object of the Invention] The object of the present invention is to manufacture a textured wood decorative board that does not cause poor adhesion.

This invention includes a back plate, a plate-shaped core disposed at an intermediate portion other than the end of the back plate, a core material disposed at the end of the back plate, a flat plate-shaped end, and an uneven intermediate portion. a surface plate which is superimposed and fixed on the core material and the plate-shaped core with the flat plate-shaped end facing the core material and the middle part facing the plate-shaped core, and the thickness of the core material is as described above. The gist is a textured wood decorative board that is larger than the thickness of the plate-shaped core and has a curved portion between the flat end of the surface board and the uneven middle part. .
つぎに、この発明を実施例にもとづいて詳しく
説明する。 Next, the present invention will be explained in detail based on examples.
第２図はこの発明の一実施例の製造説明図であ

着剤を介して重ねるとともに、芯材３を重ねる。
この場合、芯材３の厚み寸法はフエザーコア２の
厚み寸法よりも大きく設定され一定の高さ寸法差
が生じるようになつている。そして、このフエザ
ーコア２および芯材３の上に、平板状端部６ａお
よび凹凸状中間部６ｂ並びにわん曲部６ｃを備え
た表面板６を、図示のように凹凸状上中間部６ｂ
をフエザーコア２に対峙させるとともに平板状端
部６ａを芯材３の表面に対峙させた状態で接着剤
を介して重ね、これをゴム板７を備えた押圧板８
で加圧することにより製造される。 FIG. 2 is a manufacturing explanatory diagram of an embodiment of the present invention. That is, the feather core 2 is stacked on the back plate 1 via an adhesive, and the core material 3 is stacked thereon.
In this case, the thickness of the core material 3 is set larger than that of the feather core 2, so that a certain difference in height occurs. Then, on the feather core 2 and the core material 3, a surface plate 6 having a flat end portion 6a, an uneven intermediate portion 6b, and a curved portion 6c is attached as shown in the figure.
facing the feather core 2 and overlapping them with an adhesive, with the flat end portion 6a facing the surface of the core material 3, and then attaching this to the pressing plate 8 provided with the rubber plate 7.
It is manufactured by applying pressure.
この場合において、芯材３の厚み寸法とフエザ
ーコア２の厚み寸法の差が許容量以上であつても
わん曲部６ｃがわん曲しその寸法誤差を吸収す

なつている。したがつて、芯材３とフエザーコア
２の厚み寸法の差が許容量を超えていても、わん
曲部６ｃがわん曲して許容量を超えた分の寸法差
を吸収するのである。 In this case, even if the difference between the thickness of the core material 3 and the thickness of the feather core 2 is greater than the allowable amount, the curved portion 6c is curved to absorb the dimensional error. That is, since the curved portion 6c is curved in advance, it is in a state with extremely high bendability. Therefore, even if the difference in thickness between the core material 3 and the feather core 2 exceeds the allowable amount, the curved portion 6c bends to absorb the dimensional difference that exceeds the allowable amount.

差が吸収されるのである。 FIG. 3 shows a partially exploded perspective view of the uneven wood decorative board manufactured in this manner. That is, in this uneven wood decorative board, the flat end portion 6a and the uneven intermediate portion 6b of the surface board 6 are firmly adhered to the surface of the core material 3 and the surface of the feather core 2, respectively, and no adhesion failure occurs. That is, as shown in FIG. 4, when the thickness difference h between the feather core 2 and the core material 3 is smaller than the appropriate value, the flat end portion 6a is bent from the curved portion 6c and curved along the chain line A shown in the figure. The dimensional error will be absorbed. On the other hand, if the thickness of the core material 3 is large and the difference h from the height of the feather core 2 is larger than the appropriate value, the flat end portion 6
A is curved upward from the solid line, and the dimensional error is absorbed.
このように、この凹凸木質化粧板は、芯材３と

Therefore, no adhesion failure occurs at all.

がつて、接着不良が全く生じない。(Effects of the Invention) Since the uneven wood decorative board of the present invention is constructed as described above, even if there is variation in the thickness dimension between the core material and the plate-like core such as a feather core, the variation will be absorbed by the surface board. It is absorbed at the curved part.Therefore, no adhesion failure occurs at all.

より製造される。 The surface plate 6 of the uneven wood decorative board is an upper mold 1 having an uneven surface as shown in FIG.
The wood veneer laminate 16 is placed between the 0 and the corresponding lower mold 11, and the wood veneer laminate 16 is pressurized with the press upper mold 13 and the press lower mold 14 via the hot plate 12.

着状態が一層良好になる。 In this case, tensile force acts on the portions of the wood veneer laminate 16 that correspond to the unevenness of the mold surfaces of the upper mold 10 and the lower mold 11 during pressure molding. Therefore,
That part stretches and becomes thinner. Therefore,
The resulting uneven wood decorative board is shown in Figure 6.
The thickness t of the flat end portion 6a is greater than the thickness of the uneven intermediate portion 6b. Therefore, if the spacing between the upper mold 10 and the lower mold 11 is set to be the same, sufficient pressure will not be applied to the uneven intermediate portion 6b, resulting in incomplete formation of the unevenness or failure of adhesion. There is a problem with becoming complete. Therefore, as shown in FIG. 7, the intervals between the upper die 10 and the lower die 11 are not all the same, but the interval t 2 between the uneven parts and the interval t 3 between the curved parts are the same as the interval between the flat parts. It is desirable to set it to be smaller than t1 . In particular, when the thickness of t 2 is set to t 2 = t 1 -0.1t, the uneven intermediate portion 6b of the surface plate 6 is formed into a predetermined uneven shape, and no bonding defects occur, resulting in the most favorable result. You will be able to do it. In addition, by setting t 3 smaller than t 1 , the thickness of the curved portion 6c of the surface plate 6 becomes thinner, making it easier to curve, so that the adhesion state of the surface plate 6 to the feather core 2 and the core material 3 decreases. becomes even better.
