DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a decorative wooden flooring material excellent in decorativeness and workability.

[0002]

2. Description of the Related Art Conventionally, as wood-type decorative flooring of this kind, a decorative edge having a V-shaped cross section in the vertical, horizontal or both directions has been formed on the decorative panel surface by obliquely chamfering the upper edge of the decorative panel. The formation of a rift is well known.

[0003] However, in the case of the above-mentioned obliquely chamfered or V-shaped decorative joint grooves, there is no soft feeling, so for example, as shown in FIG. Is proposed in the form of a curved surface (see JP-A-7-88992). In this proposal, for example, when adjacent decorative flooring materials A, A are joined to each other by actual bonding, an joint groove 12 'is formed between the decorative flooring materials A, A in which both opposing side surfaces are curved. As a result, a soft feeling and a walking feeling can be improved.

[0004]

However, in the above-described conventional apparatus, the decorative floor material A,
When a gap 16 is formed at the actual joint between A, the gap 16
However, there is a problem that it is noticeable. Moreover, the joint groove 12 '
Garbage, dust and the like easily enter the gap 16 and once the dust and the like enter the gap 16 and become clogged, it is difficult to remove the dust and the like in that state, and cleaning becomes difficult.

[0005] The present invention has been made in view of the above, and an object of the present invention is to improve the shape and structure of the upper edge corners of the decorative flooring as described above to improve the space between adjacent floors. Even if a gap is formed in the joint groove, the joint groove is made inconspicuous, and dirt and the like hardly fall into the joint groove to facilitate cleaning of the joint groove.

[0006]

In order to achieve the above object, according to the present invention, in addition to an arc-shaped convex surface, a bottom surface extending substantially horizontally from the lower end thereof is formed at the upper edge corner of the decorative flooring material. Thus, the joint bottom is formed in the joint groove between the adjacent decorative floor material and the bottom surface.

More specifically, according to the first aspect of the present invention, an arc-shaped convex surface composed of an arc surface protruding outward is provided at an upper edge corner of a wooden decorative board provided with a decorative layer on the surface of a wooden substrate. And a bottom surface extending substantially horizontally from the lower end of the arc-shaped convex surface.

[0008] According to the above configuration, the decorative flooring is provided with an arc-shaped convex surface formed of an arcuate surface protruding outward at the upper edge corner of the wooden decorative board, so that the decorative flooring materials are arranged and joined together. In this case, an arc-shaped groove having curved surfaces on both sides is formed between the two decorative flooring materials by the arc-shaped convex surface, so that a soft feeling and a walking feeling can be improved.

Moreover, since the bottom surface extending substantially horizontally from the lower end of the arc-shaped convex surface is provided, the joint groove formed by the bottom surface is formed in the joint groove between the two decorative flooring materials. For this reason, even if a gap is generated between adjacent decorative flooring materials due to a dimensional change of the decorative flooring material, the joint bottom becomes more conspicuous,
As a result, the gap is less noticeable, and the appearance of the joint can be improved.

[0010] Even when dirt or dust falls into the joint groove between the decorative flooring materials, most of the dust stays at the joint bottom,
The dirt and the like accumulated at the joint bottom are harder to be pushed into the gap any more, and the dirt and the like can be easily removed from the joint groove to facilitate the cleaning.

According to the second aspect of the present invention, an arc-shaped convex surface composed of an arc surface protruding outward and an arc-shaped convex surface are provided at the upper edge corner of a wooden decorative board provided with a decorative layer on the surface of the wooden substrate. And a bottom surface extending substantially horizontally from the lower end of the arc-shaped concave surface, the arc-shaped concave surface continuing from the lower end of the arc-shaped concave surface and inwardly concave.

With this configuration, the same operation and effect as the first aspect of the invention can be obtained. In addition, since the arc-shaped convex surface and the bottom surface are connected by an arc-shaped concave surface composed of an arc-shaped surface depressed inward, when the surface is painted by a flow coater, a sponge roll, or the like during the production of a decorative flooring material. The contact angle of the paint to the arc-shaped concave surface between the arc-shaped convex surface and the bottom surface can be increased to improve the wettability. The finish can be beautiful.

According to the third aspect of the present invention, a rising side wall is provided on the upper edge portion of the decorative board of the decorative flooring material so as to extend linearly in a substantially vertical direction continuously to the upper end of the arc-shaped convex surface. By this, when performing the curved surface processing of the arc-shaped convex surface by a grinding means such as brush grinding, the rising side wall serves as a guide of the grinding means such as the blade of the brush, so that the surface is not ground, and the arc-shaped convex surface is favorably formed. It can be a smooth surface.
In addition, the rising side wall clearly separates the horizontal surface, which is the surface, from the arc-shaped convex surface, so that the decorative side wall with the arc-shaped convex surface is emphasized rather than a decorative decorative good appearance.

According to a fourth aspect of the present invention, the portion of the substrate corresponding to the upper edge of the decorative board is made of a wood fiber board having a specific gravity of 0.6 or more. When wood fiberboard is used in this way, there is little vertical and horizontal directionality like plywood, and therefore, such as plywood, especially at the upper edge in the direction orthogonal to the fiber direction, the bolus cross section of conduit, temporary pipe, wood fiber Can be prevented, and the upper edge fiber can be prevented from becoming fuzzy without being cut cleanly, preventing the arc-shaped convex surface from becoming rough, and cutting the curved side wall better. Or, it can be ground.
