Description

  The present invention relates to a decorative board provided with a decorative groove used for interior goods such as doors and wall materials and storage goods such as furniture, and more specifically, decorative grooves of various shapes are produced from a single substrate. It is about a decorative board.

  Conventionally, interior goods such as doors and wall materials, and storage goods such as furniture have been subjected to V-shaped, bowl-shaped and inverted trapezoidal decorative groove processing on the surface. As shown in the prior art of Patent Document 1, this decorative groove processing is usually produced by applying a V-shaped cutting groove on the surface of a substrate and then attaching a decorative sheet to the cutting surface.

  In addition, there is a decorative plate in which a V-shaped decorative groove is processed by attaching a decorative sheet to a cutting surface after providing a flat portion at the bottom of a V-shaped cutting groove as in Patent Document 1.

  And like patent document 2, V-shaped cutting groove processing is performed from the back surface of a board | substrate, and after that, this cutting surface is expanded and it adheres on a base plate, and V-shaped decorative groove processing is made | formed on the surface of the board | substrate. There is also a decorative board.

  Further, as in Patent Document 3, two V-shaped cutting grooves are processed from the back surface of the substrate, and then two substrates having a substantially J-shaped cross section are prepared by bonding the cutting surfaces. There is also a decorative board in which a V-shaped decorative groove is formed on the surface of the substrate by fitting the substantially J-shaped substrate into the base plate provided with the base plate.

  However, with the conventional method of attaching a decorative sheet to the cutting surface, if the width of the decorative groove is small or the depth of the groove is large, the decorative sheet does not sufficiently enter the bottom of the decorative groove. There was a problem that the decorative sheet floated. On the other hand, when the decorative sheet is pressed against the bottom of the groove to prevent lifting, the decorative sheet is broken, causing water absorption from the damaged portion, resulting in a decrease in durability.

  Further, in the decorative plate shown in Patent Document 1, by providing a flat portion at the bottom of the decorative groove, the decorative sheet can be prevented from being lifted or damaged, but a texture such as the sharpness of the V-shaped decorative groove can be expressed. There was a problem that it was difficult.

And in the decorative board shown in patent document 2, since the decorative sheet has adhered to the bottom of the V-shaped decorative groove, the sharpness of the decorative groove can be expressed, but the V-shaped decorative groove is formed. Therefore, since an air layer is formed between the substrate and the base plate by bonding to the base plate, the final product cannot be manufactured by press molding.
Therefore, when it became the final product, there was a problem that sufficient strength could not be given to the hollow part.

  Furthermore, in the decorative board shown in Patent Document 3, it is necessary to prepare a V-shaped cutting groove and prepare two substrates having a substantially J-shaped cross section, and to provide a fitting groove on the base plate. There is a problem that the work process becomes complicated.

  The present invention has been made in view of the above-described conventional problems, and is a substrate that does not impair the sharpness of the decorative groove while keeping the decorative sheet in close contact with the bottom of the decorative groove, and one sheet. An object of the present invention is to provide a decorative plate in which a decorative groove is produced only with a substrate and the base plate does not require processing.

To achieve the above object, a decorative board according to claim 1 of the present invention is a decorative board that includes a substrate and a decorative sheet that covers the surface of the substrate, and has a decorative groove formed on the surface thereof. on the back surface of the substrate on which the decorative sheet is attached, with a vertical sidewall surfaces, the first horizontal bottom forming surface parallel to the decorative sheet was cut formed to reach the board in a substantially decorative sheet on both sides, the two first Two first vertical bottom constituent surfaces and two second vertical bottom constituent surfaces rising vertically from the horizontal bottom constituent surface perpendicular to the opening direction of the cutting groove, and the first horizontal connected to the first vertical bottom constituent surface A bottom forming surface, the parallel second horizontal bottom forming surface, an inverted V-shaped bottom forming surface between the first horizontal bottom forming surface and the both side wall surfaces, the inverted V-shaped bottom forming surface, and the second The first horizontal bottom component surface connected to the vertical bottom component surface; A third horizontal bottom component surface, the inverted V-shaped bottom component surfaces are bonded together, the first horizontal bottom component surface and the second vertical bottom component surface are bonded, and the side wall surface and the first 3 horizontal bottom component surfaces and the first vertical bottom component surface are bonded, and the surface of the bonding portion between the first horizontal bottom component surface and the second vertical bottom component surface is folded and bonded to the substrate surface. The decorative groove has a cross-sectional shape.

A decorative board according to a second aspect of the present invention is the decorative board according to the first aspect, wherein the height of the side wall surface and the sum of the width of the third horizontal bottom component surface and the height of the first vertical bottom component surface are the same length. It is characterized by being.

  Here, the board | substrate used for this invention can be used also for board | plate materials of woody materials type | system | groups, such as a plywood, MDF, LVL, a particle board as well as wood. Moreover, it can also be used for an inorganic material-based plate material such as a calcium silicate plate.

  The decorative sheet used in the present invention is not particularly limited as long as it can be adhered to the substrate and can make the surface, and a veneer generally used as a decorative material for building materials can be used. Moreover, synthetic resin sheets such as vinyl chloride resin, polyethylene resin, and polypropylene resin can also be used. These veneer plates and synthetic resin sheets may be appropriately colored or patterned.

In addition, in this invention, it is preferable to provide the horizontal bottom part construction surface parallel to a decorative sheet between the four bottom part construction surfaces arrange | positioned by side view W shape, and a side wall surface.
Here, the width of the horizontal bottom portion constituting surface is preferably 0.05 to 1.0 mm, and more preferably 0.1 to 0.3 mm.
The reason is that by making such play, it is possible to prevent the decorative sheet from being broken or whitened by being stretched at the bent portion when the cut surface is bent and bonded.
In addition, by making such play, the cutting surface can be made without the pre-treatment work of heating the substrate, which was conventionally necessary to prevent the decorative sheet from being broken at a low temperature in winter. This is because it can be folded.
Therefore, when the width of the flat portion is smaller than 0.1 mm, the decorative sheet cannot be sufficiently broken or whitened when folded. On the other hand, if the width of the flat part is larger than 0.3 mm, the decorative sheet is left in the folded part when folded and the appearance is deteriorated.

  On the other hand, the thickness of the horizontal bottom portion constituting surface may be in a state of reaching substantially the decorative sheet. This means that the thickness is not limited as long as the bending operation is not difficult at the time of bending, and therefore, the substrate may be cut with a slight substrate left on the horizontal bottom component surface, or The entire substrate may be cut leaving only the decorative sheet.

A decorative board according to the invention of claim 1 is a decorative board that includes a substrate and a decorative sheet that covers the surface of the substrate, and has a decorative groove formed on the surface, and the decorative sheet is attached to the surface of the substrate. on the back, perpendicular sidewall surfaces, comprising a base plate of the first horizontal bottom forming surface parallel to both sides decorative sheet was cut formed until a substantially decorative sheet, each cut groove from both the first horizontal bottom forming surface Two first vertical bottom component surfaces and two second vertical bottom component surfaces rising perpendicular to the opening direction, and a second horizontal bottom component surface parallel to the first horizontal bottom component surface connected to the first vertical bottom component surface And an inverted V-shaped bottom configuration surface between the first horizontal bottom configuration surface and both side wall surfaces, and a first horizontal bottom configuration surface connected to the inverted V-shaped bottom configuration surface and the second vertical bottom configuration surface. A third horizontal bottom component surface, and the inverted V-shaped bottom component surfaces are bonded together. The first horizontal bottom component surface and the second vertical bottom component surface are bonded, the side wall surface, the third horizontal bottom component surface, and the first vertical bottom component surface are bonded, and the first horizontal bottom component surface and the first (2) The surface of the bonding portion with the vertical bottom surface is folded and bonded to the substrate surface, whereby a decorative groove having a cross-sectional shape is formed on the surface.
Therefore, since the decorative groove can be formed on the surface with the decorative sheet attached by folding the back surface, the makeup does not impair the sharpness of the decorative groove while bringing the decorative sheet into close contact with the bottom of the decorative groove. A plate can be made.
In addition, when the cut surface is bent and bonded, the decorative groove opening is formed in a state where the substrate is wound, so that a decorative plate with improved decorative groove strength can be produced.

The decorative board according to the invention of claim 2 is configured such that the height of the side wall surface and the sum of the width of the third horizontal bottom component surface and the height of the first vertical bottom component surface are the same length.
Therefore, the decorative plate can be produced in which the back surface of the decorative plate becomes flat after being bent, and the base plate is provided with a square-shaped decorative groove on the surface without the need for processing the fitting groove.
Furthermore, since the back surface of the decorative plate is flat, the decorative plate can be fixed to the base plate by pressing, and a decorative building material that maintains strength without having a hollow structure can be produced.
