BACKGROUND OF THE INVENTION
The present invention relates to a floor board, and more particularly to its actual shape.
[0002]
[Prior art]
In the conventional floor board, for example, an actual shape as shown in FIG. 4 is adopted. When coating the surface of the floor board having this actual shape with a coating device such as a roll coater, the locations indicated by the thick lines in the figure, that is, the floor board surfaces a and a and the floor groove forming slopes b and b, and further necessary Accordingly, the upper surface c of the male front end portion is painted. However, if a gap is generated in the fitting portion between the floor boards, the unpainted portions d and e are exposed on the surface, and the aesthetic appearance is impaired.
[0003]
In order to solve such a problem, for example, as described in Patent Documents 1 and 2 below, the top end side of the male end is cut out to form a concave step portion, and the upper end portion on the female end side protrudes. A projecting piece that can be engaged with the concave step portion is formed so that the projecting piece is slidably mounted on the concave step portion when the male and female are fitted and laid. ing.

Japanese Utility Model Publication No. 8-3561 [Problem to be Solved by the Invention]
If the upper surface of the concave step portion is applied after adopting the actual shape as described in the above Patent Documents 1 and 2, even if a gap occurs in the fitting portion between the floor plates, the coating Since the unpainted portions d and e (FIG. 4) are not exposed only by exposing the surface, the effect of not deteriorating the aesthetic appearance is exhibited.
[0005]
However, when adopting the above-mentioned actual shape, the male-side concave stepped portion and the female-side protruding piece must be formed within the thickness range on the surface side of the fitting portion between the male and female. Inevitably, the thickness of the protruding piece is inevitably thin, and when an excessive load is applied to the fitting portion of the floor board, the protruding piece may be damaged, such as a crack or a crack.
[0006]
[Means for Solving the Problems]
Therefore, the present invention solves the above-described problem and has a novel effect of maintaining the aesthetic appearance without exposing the unpainted portion even when a gap is generated in the fitting portion between the floor plates without causing a decrease in strength. The purpose is to provide a shape.

[0011]
According to a fourth aspect of the present invention, in the floor board according to any one of the first to third aspects, each of the non-exposed surface and the exposed surface is a surface shape that does not include a vertical surface and a horizontal surface portion.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of a floor board according to the present invention will be described with reference to FIGS. 1 to 3. The floor board 10 is made of plywood, wood fiber board (MDF, etc.), wood chipboard, veneer laminated board and other wood materials, and the size thereof is not particularly limited. For example, the width is about 300 mm and the length. It is around 1800 mm and the thickness is 9 to 17 mm.
[0013]
A male fruit 11 is formed on one of a pair of opposed edges of the floor board 10, and a female fruit 12 is formed on the other. An inclined surface 14 that is inclined at a predetermined angle from the male side edge of the surface 13 is formed above the male fruit 11, and the same angle as that of the inclined surface 14 from the female side edge of the surface 13 is above the female fruit 12. An inclined surface 15 inclined at is formed. The inclined surfaces 14 and 15 cooperate to provide a V-shaped floor groove when the floor boards 10 and 10 are connected together by fitting the male fruit 11 and the female fruit 12 together. In the illustrated embodiment, the V-shaped floor grooves are formed as the flat inclined surfaces 14 and 15, but this is only an example, and the inclined surfaces 14 and 15 are formed as arcuate surfaces. A semicircular arc shape or a substantially U-shaped floor groove can be formed at the time of floor plate connection by fitting, or any other floor groove forming surface for forming a floor groove of any other shape can be formed.
[0014]
On the male fruit 11 side, a vertical surface 16 is vertically formed from the base end of the male fruit 11, and an arcuate convex surface 17 is formed between the upper edge and the lower edge of the inclined surface 14. On the female fruit 12 side, a vertical surface 18 is vertically formed from the opening edge of the female fruit 12, and an arcuate concave surface 19 is formed between the upper edge and the lower edge of the inclined surface 15. The arcuate convex surface 17 and the arcuate concave surface 19 are formed in an arc shape having substantially the same radius of curvature so that they can be engaged with each other.
[0015]
The arcuate convex surface 17 on the male 11 side is formed so as to gradually recede from the lower edge of the inclined surface 14 obliquely downward, and has no vertical surface. Similarly, the arcuate concave surface 19 on the female fruit 12 side is formed so as to gradually protrude obliquely downward from the lower edge of the inclined surface 15 and has no vertical surface.
[0016]
Preferably, the height (h2) of the arcuate concave surface 19 on the female fruit 12 side is 2/3 or less of the distance (H2) between the floor plate surface and the female fruit upper surface, and the horizontal width thereof is 0.5. ~ 2mm. Correspondingly, the height of the arc-shaped convex surface 17 (h1) is equal to or less than 2/3 of the distance (H1) between the floor plate surface and the upper surface of the male body, and the shape on the male body 11 side is also horizontal. The direction width is preferably 0.5 to 2 mm. The height (h1) of the arcuate convex surface 17 on the male fruit 11 side and the height (h2) of the arcuate concave surface 19 on the female fruit 12 side are the same.
[0017]
Since the arcuate concave surface 19 has a height (h2) that is 2/3 or less of the distance (H2) between the floor plate surface and the actual upper surface, makeup on the arcuate concave surface 19 is facilitated, especially when painting is performed. It becomes easy to paint over the front surface up to the lower edge of the arcuate concave surface 19.
[0018]
Further, by setting the horizontal width of the arcuate concave surface 19 to 2 mm or less and the horizontal width of the arcuate convex surface 17 corresponding to this, the projecting dimensions are reduced, and from the surface of the floor plate fitting portion. Even when a large load is applied, damage such as cracking is less likely to occur. In addition, when the width dimension of the floor board 10 is about 300 mm as usual, the size of the gap that can be generated by contraction in the mating portion between the male fruit 11 and the female fruit 12 is generally 2 mm or less. If the horizontal widths of 17 and the arcuate concave surface 19 are set to 2 mm or less in accordance with this, good aesthetics can be maintained without causing exposure of unpainted portions, as will be described later. Further, if the width in the horizontal direction is less than 0.5 mm, the unpainted upper surface of the male 11 may be exposed from between the vertical surfaces 16 and 18 when a gap is generated in the fitting portion, and the appearance may be deteriorated. Therefore, in order to prevent this, the horizontal width is preferably 0.5 mm or more. Therefore, it is preferable that the horizontal widths of the arcuate convex surface 17 and the arcuate concave surface 19 are both in the range of 0.5 to 2 mm.
[0019]
In the floor board 10 having the actual shape as described above, similarly to the prior art (FIG. 4), the surface 13 and the inclined surfaces 14 and 15 and, if necessary, the upper surface of the front end of the male fruit 11 are coated. At the same time, a similar coating is applied to the arcuate concave surface 19 on the female fruit 12 side (the painted surface is indicated by a thick line).
[0020]
In addition, in this embodiment, makeup by painting is applied, but makeup by sticking a cosmetic material may be applied to the above-mentioned places. As a decorative material in this case, use natural veneer, artificial veneer, non-woven fabric, paper, synthetic resin sheet (olefin resin, vinyl chloride resin, polyester resin, acrylic resin sheet, etc.) obtained by cutting natural wood. Can do. Or you may use what printed various patterns on the sheet | seat of a flexible material. Furthermore, a composite sheet obtained by pressure-bonding a paper between synthetic resin sheets, an impregnated paper impregnated with a synthetic resin, or the like can also be used as a cosmetic material. An optional top coat may be further applied after the decorative material is adhered. The thickness of the decorative material used is generally arbitrarily selected within a range of 0.05 to 1 mm. As an adhesive for adhering decorative materials to floorboard equipment, use a thermoplastic adhesive such as vinyl acetate resin mixed with thermosetting resin or urea powder to improve water resistance. Can do.
[0021]
In this floor board 10, since a series of makeup | decoration is given to the circular-arc-shaped concave surface 19 which continues below from the inclined surface 15 by the side of the female fruit 12, the male fruit 11 and the female fruit 12 of the floor board 10 were fitted. in the state (FIG. 2), even if there is a gap between the Omi 11 and Mesumi 12, the bottom portion of the V groove formed by the inclined surfaces 14 and 15, a circle with makeup (paint) is applied Only the arc-shaped concave surface 19 is exposed to the surface side, and no unpainted portion is exposed, and the aesthetic appearance is not deteriorated.
[0022]
In the present invention, the case where the nail 20 is driven from the male 11 into the floor base (not shown) in a state where a gap is provided between the inclined surfaces 14 and 15 as shown in FIG. In the initial stage of construction, the present invention can be applied to both cases where the lower edges of the inclined surfaces 14 and 15 are brought into close contact with each other so that there is no gap.
[0023]
In the latter case, a V groove (floor groove) having no gap is formed at the bottom of the mating surface between the floor boards 10 and 10 at the beginning of construction, and the floor board 10 made of wood material is dried and contracted over time. Even if there is a gap at the bottom of the groove, as long as the gap is within the range of the arcuate concave surface 19, only the painted arcuate concave surface 19 is exposed on the surface side, and no coating is applied. Since the portion is not exposed, a good aesthetic can be maintained for a long time.
[0024]
In the former case, since the gap is provided between the inclined surfaces 14 and 15 from the beginning of the construction, the arc-shaped concave surface 19 is exposed from the bottom of the V-groove formed by them, as described above. Since the surface is pre-painted, there is no concern about aesthetic degradation, and even if the wooden board 10 is dried and contracted over time and the gap becomes large, the gap is within the range of the arcuate concave surface 19. Since the unpainted portion is not exposed, a good aesthetic can be maintained for a long time. Furthermore, in the former case, even when the moisture content of the floorboard 10 which is a wooden material increases and expands, there is an advantage that it can be absorbed if it is within the gap formed from the beginning. .
[0025]
In addition, it is preferable that the protruding dimension of the male fruit 11 is formed in advance slightly smaller than the groove depth (retracted dimension) of the female fruit 12.
[0026]
Further, according to the actual shape of the floor board 10, the male fruit 11 is fitted into the female fruit 12, and the female fruit 12 and the circular arc shape are provided between the upper surface of the male fruit 11 and the arcuate convex surface 17. Since it is fitted in such a manner that the convex portion 21 is sandwiched between it and the concave surface 19, the fitting strength is increased, and no unevenness or a step is generated in the fitting portion, so that excellent durability against casters is exhibited. To do.
[0027]
Although the present invention has been described with reference to the illustrated embodiments, the present invention is not limited to this, and various modifications can be made within the scope of the invention described in the claims.
[0028]
The male-side arcuate convex surface 17 and the female-side arcuate convex surface 19 are not limited to the shapes shown in the illustrated embodiment, and the former is obliquely downward from the lower edge of the inclined surface 14 as the floor groove forming surface. As the one that gradually retreats, the latter one that protrudes obliquely downward from the lower edge of the inclined surface 15 as the floor groove forming surface, both of which are formed without including the vertical plane and the horizontal plane portion. Any shape can be included. For example, it may be formed as an inclined surface on a plane inclined at a predetermined angle. In this case, when the floor groove forming surface on the female side is the inclined surface 14, it is formed as an inclined surface that is continuous at the same angle as the inclined surface 14 or an inclined surface having an inclination angle different from that of the inclined surface 14. be able to.
[0029]
Further, in the case of forming as an arc surface or a curved surface, the male side is a convex surface 17 and the female side is a concave surface 19 in the illustrated embodiment, but conversely, the female side may be a convex surface and the male side may be a concave surface. .
[0030]
In addition, it is preferable that these surfaces 17 and 19 have a shape that can be substantially engaged when the male fruit 11 and the female fruit 12 are fitted to each other. A shape in which a gap is formed may be adopted.
[0031]
【The invention's effect】
According to the floorboard of the present invention, even if the floorboard, which is a wood material, is dried and contracted over time and a gap is generated in the fitting portion between the wood materials, the lower edge of the floor groove forming surface on the female side The surface that gradually protrudes from the female edge toward the opening edge of the female body is only exposed on the surface, and since this surface is pre-painted such as painting, no unpainted portion is exposed. Can hold a good aesthetic.
[0032]
In addition, since both the surface on the female fruit side and the surface formed on the male fruit side corresponding thereto are configured so as not to include the horizontal plane part, the upper part of the male fruit and the female fruit becomes too thin. Since a predetermined thickness can be ensured, even if an excessive load is applied to the mating portion of the floor board, damage such as cracking or cracking does not occur.
[0033]
Furthermore, according to the characteristic actual shape adopted by the present invention, in the mating portion of the floor board, in addition to the mating of the male and the female, between the non-exposed surface on the male side and the upper surface of the male The protrusions above the female body are fitted to each other, and a stronger fitting is realized, and the action of pressing down the female body side is also exerted more strongly. Improves.
