Description

  The present invention relates to a door panel configured by adhering a decorative material along the surface of a core material.

  Conventionally, for example, a door used for an opening of a house or the like is one of the important elements for giving a sense of quality to be thick and heavy. However, it is necessary to be light in terms of practical use such as mounting. In general, a long door panel is required to have a high strength that does not cause bending or the like.

  As a technique corresponding to the above purpose, a cosmetic paste is attached to at least one surface of a wooden board as shown in FIG. 5, which is disclosed in Japanese Utility Model Publication No. 7-23188, and is applied to one surface. If only the cosmetic exhibition sticker is attached, if the cosmetic exhibition sticker is attached to the surface opposite to the surface where the cosmetic exhibition paste is attached, or both surfaces The end of the wooden board is folded back by a notch provided on one of the surfaces, and the groove provided on the inner surface of the folded wooden board end, and the folded wooden board The groove provided on the surface of the wooden board in contact with the end of the system board is opposed to at least a part of the groove opening, and the reinforcing member 101 is provided in the cavity formed by the groove. There is a door 100 made of a decorative board inserted.

  The door 100 is thick because the decorative board is formed by folding the end of the wooden board, so that it looks heavy but is lighter than it looks. The decorative board is reinforced to the folded wooden board, and the inner surface of the folded wooden board end and the surface of the wooden board where the folded wooden board end is joined by the reinforcing member 101. Therefore, it is assumed that the strength is higher. In particular, it is assumed that even a long object is difficult to bend.

However, according to this configuration, the end portion of the wooden board is folded back by the notch portion, and therefore, due to the variation in processing accuracy for forming the notch portion, the folding or overlapped joint portion is spaced apart. There is a concern that or a step may be generated, or that a decorative sheet such as a vinyl chloride sheet printed with a wood grain pattern or the like attached to the surface of the base material of the wooden board is lifted.
