With the above configuration, the upper edge corner of the decorative wood flooring board is provided with an arc-shaped convex surface formed of an arc surface protruding toward the outside. A joint groove in which both side surfaces are curved is formed by the arc-shaped convex surface between the decorative flooring materials, and the soft feeling and the walking feeling can be improved.
[0009]
And since the bottom face extended horizontally from the lower end of the said arc-shaped convex surface is provided, the joint bottom which consists of a horizontal flat surface by the said bottom face is formed in the joint groove between both decorative flooring materials. For this reason, even if a gap occurs between adjacent decorative flooring materials due to a change in the size of the decorative flooring material, the joint floor becomes more conspicuous, and the appearance of the joints becomes less noticeable. Can be increased.
[0010]
Even when dirt or dust falls in the joint groove between the two decorative flooring materials, most of the dust stays on the joint floor consisting of the above horizontal flat surface, and any dust collected on the joint floor is further removed. It becomes difficult to be pushed in, and dust can be easily removed from the joint groove to facilitate cleaning.

In the invention of claim 2, an arcuate convex surface comprising an arcuate surface projecting outward at the upper edge corner of the woody decorative board provided with a decorative layer on the surface of the wooden substrate, and a lower end of the arcuate convex surface An arc-shaped concave surface consisting of a continuous arc-shaped concave surface and a bottom surface extending horizontally from the lower end of the arc-shaped concave surface is provided, and the arc shape of both floor materials when joined to other floor materials. The convex surface, the arc-shaped concave surface, and the bottom face are formed so as to form a joint groove facing left and right, and the bottom wall of the joint groove is formed on the joint base composed of a horizontal flat surface by the bottom surfaces of both floor materials. It shall be.
[0012]
If it carries out like this, there can exist an effect similar to invention of the said Claim 1. In addition, since the arcuate convex surface and the horizontally extending bottom surface are connected by an arcuate concave surface consisting of an arcuate surface that is recessed inwardly, the surface is coated with a flow coater, sponge roll, etc. When painting, the paint contact angle with the arcuate concave surface between the arcuate convex surface and the bottom surface can be increased to improve wetting, and even with a flow coater, sponge roll, etc. The finish of the flooring can be made beautiful.
[0013]
In the invention of claim 3, a rising side wall is provided on the upper edge portion of the wooden decorative board in the decorative flooring material and extends linearly in a substantially vertical direction continuously from the upper end of the arcuate convex surface. Therefore, when the curved surface of the arc-shaped convex surface is processed by a grinding means such as brush grinding, the rising side wall serves as a guide for the grinding means such as the blade edge of the brush, so that the surface is not ground and the arc-shaped convex surface is improved. It can be made smooth. In addition, the rising side wall clearly separates the horizontal surface, which is the surface, from the arcuate convex surface, so that a decorative appearance with good decorativeness can be obtained in which the curved side wall made of the arcuate convex surface is emphasized.
[0014]
