DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative wooden flooring, and more particularly to a decorative wooden flooring having a decorative groove on its surface.

[0002]

2. Description of the Related Art A conventional wooden decorative flooring has a decorative groove shape in a cross section of a flooring main body 3 in which a wooden decorative veneer 2 is adhered to a wooden base material 1 as shown in FIG. A decorative groove 6 having a V-shaped cross-section formed from a portion of the veneer veneer veneer 2 on the surface, that is, a decorative flute having a V-shaped cross-section and a decorative horizontal groove having a V-shaped cross-section formed in a direction orthogonal to the surface. General. As the groove cross-sectional shape of the decorative groove 6, in addition to the V-shaped shape, a groove having a U-shaped cross-section or a square-shaped cross-section is also known.

[0003] Among the above-mentioned decorative groove shapes, the square groove has a large groove bottom and is square, so that unless the groove bottom is polished well with a sander, there is a significant defect in cleaning suitability and design. Furthermore, in the case of a square groove or a U-shaped groove, it is easy for the wood decorative veneer or the wood fiber of the wood base material to grow at the corners of the upper end edge of the groove, and the sole of the groove when walking is the upper end edge of the groove. They often come in contact with the corner Sasakure and feel uncomfortable when walking, and in severe cases, the Sasakure can break socks and women's stockings, and these drawbacks become a problem. I was

Accordingly, as a sectional shape of the decorative groove, a V-shaped groove having a sectional shape as shown in FIG.
The U-shaped groove also has various disadvantages described below.

That is, in the case of the wooden decorative flooring in which the decorative groove 6 is the V-shaped groove, it is not possible to fully utilize the real design of the wooden veneer 2 and the poorness of the groove itself.
Inevitably, it was inferior to floor boards made of solid wood. Therefore, in order to compensate for the poorness of the groove itself, it is conceivable to increase the groove width W itself. However, in the conventional V-shaped groove, when the groove width W is increased, the angle of the groove bottom becomes large and the obtuse angle becomes obtuse. In addition, the three-dimensional appearance is poor, and the appearance is significantly reduced in design. To prevent it, groove depth H
It is conceivable that the depth is too deep, but if it is too deep, the underlying wooden substrate 1 is largely exposed, and unless the portion is polished well, the inner surface of the groove becomes very unsightly in appearance,
The suitability for cleaning is slightly deteriorated, and the depth H of the groove is naturally limited. Therefore, there is naturally a limit to the groove width W, and it is difficult to enhance the design by emphasizing the groove. Therefore, the design has to be somewhat poor, and it is inevitable that the woody makeup has a rich three-dimensional feeling and a soft taste. There was a problem that a floor material could not be formed.

Further, when the inclination angle α of the upper end portion of the decorative groove 6 is small, the angle of the upper end edge Q of the decorative groove 6 is small.
Not only poor foot walking feeling but also the occurrence of wood fiber fluff may break socks and women's stockings.To prevent this, if the upper end inclination angle α is made extremely large, the sharpness of the groove will be lost, as before However, the design was a problem.

In order to solve the above-mentioned problems, there has been recently proposed a decorative flooring material having a curved shape in which the cross section of the decorative groove expands into the groove. Japanese Patent Application Laid-Open No. 8-28012 discloses a decorative board having curved grooves protruding outwardly in both vertical and horizontal decorative grooves as a floor material having a cross section of the decorative groove having a curved surface shape.
No. has a vertical groove with a curved groove and a horizontal groove perpendicular to it.
A decorative plate having a U-shaped groove is disclosed.

According to these wooden decorative flooring materials, since the decorative groove is a curved groove, the corner of the upper edge of the groove is rounded, so that the foot sole has a good walking sensation and the wood fiber Is less likely to occur, and there is no danger of breaking socks or women's stockings.

[0009]

However, the decorative wooden flooring material having a curved surface in which the cross section of the decorative groove swells into the groove has the following problems.

In the wooden decorative flooring disclosed in Japanese Patent Application Laid-Open No. 8-28012, since the lateral grooves have a gentler curved surface than the vertical grooves, the number of exposed conduit surfaces on the lateral grooves is small, so that the inner surface of the lateral grooves is dark. Because it does not become difficult, in that regard, it can be solved that the appearance deteriorates, but if it is made gradual enough to improve the appearance, the horizontal groove has a smaller amount of grooves on the wood decorative flooring material than the vertical groove, so the groove as Poor presence and poor overall design. Further, since the curved groove has a sharp groove bottom and both the vertical groove and the horizontal groove are curved grooves, there is a problem that the dust cannot be completely cleaned when dust accumulates near the intersection.

In the wooden decorative flooring disclosed in Japanese Unexamined Patent Publication No. Hei 10-317653, the lateral grooves have a V-shaped cross section. Therefore, the lateral grooves have a small amount of grooves on the wooden decorative flooring. At the corner of the upper edge of the groove, there is a problem that a feeling of walking on the sole is poor, and socks and stockings may be damaged.

It is an object of the present invention to provide a good feeling in foot walking feeling, to prevent the socks and stockings from being damaged at the corners of the upper edge of the groove, and to facilitate the cleaning of the inside of the groove. Another object of the present invention is to provide a decorative wooden flooring material having a decorative groove on the surface, which is excellent in design.

[0013]

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention relates to a wood decorative veneer having a woody veneer veneer attached to a surface of a flooring body having a woody veneer adhered to a wooden base material. In a wooden decorative flooring material in which decorative flutes are provided in a substantially parallel direction and decorative flutes are provided in a direction substantially perpendicular to the decorative flutes, the decorative flutes have a curved surface in a cross section in a direction orthogonal to the groove direction. The decorative lateral groove has a multi-stage V-shape having at least one or more refraction points projecting into the groove in a cross section in a direction perpendicular to the groove direction, and is sandwiched between the refraction point and the upper edge angle. It is characterized by having a chamfer.

[0014] With this configuration, the decorative vertical groove has a curved surface in a cross section in a direction perpendicular to the groove direction.
The feeling of walking on the sole of the foot is good, and the upper edge of the groove is less likely to be damaged, so that there is no risk of damage to socks and stockings. It has a multi-stage V-shape with at least one or more refraction points protruding into the shape, and has a chamfer between the refraction point and the upper edge corner, so that it is sandwiched between the refraction point and the upper edge corner. With the chamfered portion, the feel of walking on the sole is good as well as the curved surface, and the chamfered portion makes it difficult for the upper edge of the groove to be damaged, so there is no risk of damage to socks or stockings. Since the groove bottom has a V-shape, dust accumulated near the intersection with the decorative vertical groove can be cleaned relatively easily. Further, since the decorative lateral groove has a multi-stage V-shape having at least one or more refraction points protruding into the groove, it has a three-dimensional effect and allows the presence of the groove to be visually recognized. As a whole, the design becomes excellent.

[0015]
