Embodiments of the present invention will be described below with reference to the drawings.
In the following embodiments, directions such as up and down directions will be described in principle with reference to a state in which flooring is applied to the floor. Further, the flooring material 1A, which is disposed adjacent to the flooring material 1, is described as 1A, its substrate is 2A, its side edge is abutting side edge 3A, and the surface decorative material covering the substrate 2A is 6A. Since the structure is the same for both the flooring 1 and the flooring 1A, a detailed description of the flooring 1A disposed adjacent to the flooring 1 is omitted. Further, in FIGS. 2 (a) to 2 (c), some of the detailed reference numerals attached to FIG. 1 are omitted.
The flooring 1 according to this embodiment is formed on a substrate 2 made of a wood-based material, a male part 4 formed on one side end 3 of the substrate 2, and the other side end 3 of the substrate 2. The floor material 1 includes a female real part 5 and a surface decorative material 6 provided so as to cover the surface 2 a side of the substrate 2.
This will be described in detail below.

The board | substrate 2 which comprises the flooring 1 is made into the substantially rectangular flat plate body by planar view.
The configuration of the corners on the surface 2a side of the substrate 2 is not particularly limited, but the substrate 2 in the example is inclined surfaces 2c and 2c in which both corners on the surface 2a side are chamfered.
The substrate 2 is made of a wood-based material. For example, a laminate of a wood fiber board such as MDF (medium density fiber board) on the surface of a plywood or a base plate on which a wood fiber board or the like is laminated is further laminated with a protruding board. Or made of solid wood or laminated wood. The tree species of the raw material is not particularly limited, and for example, lauan, eucalyptus, falkata, rubberwood, poplar, cedar, larch, hinoki and the like can be suitably used.

A male real part 4 and a female real part 5 are respectively formed on both side end parts (not shown) in the width direction of the substrate 2 and on both side end parts 3 and 3 in the longitudinal direction (see FIG. 1A). Has been.
The male real part 4 and the female real part 5 are used as joints for connecting and joining the flooring materials 1 and 1A arranged adjacent to each other when constructed on the construction base.
As shown in FIG. 1B and the like, the male part 4 is formed so as to protrude from one side end part 3 of the substrate 2 to a protruding line. Similarly, as shown in FIG. 1B and the like, the female real part 5 is formed in the other side end 3 of the substrate 2 and is formed in a concave groove shape so that the male real part 4 of the ridge is fitted. Has been.
The shapes and configurations of the male part 4 and the female part 5 are not limited to the illustrated examples, but if the corners of the ridges of the male part 4 are chamfered as shown in the illustrated example, the flooring 1 is formed. It can be made easy to handle with no corners and can be easily fitted to the female real part 5.

A protruding portion 8 is formed on one of the side end portions 3 and 3 where the male real portion 4 or the female real portion 5 of the substrate 2 is formed.
In the illustrated example, the protrusion 8 is provided on the side end 3 where the male part 4 is formed, and is formed below the position where the male part 4 is formed. Specifically, the protrusion 8 has a substantially rectangular cross-section, and is formed in a protrusion substantially parallel to the male part 4 as shown in FIG. 1A, and below the protrusion part of the male part 4. In addition, it is provided so as to protrude on the same surface as the back surface 2 b of the substrate 2.
Thereby, since the projection part 8 is not visible from between the abutting surfaces (the side end part 3 and the abutting side end part 3A) due to actual coupling, it can be made to look good.

The formation position of the protrusion 8 is not limited to the illustrated example, and may be the side end 3 where the female real part 5 is formed. Further, the formation position of the protrusion 8 is not limited to the lower side of the male part 4 as shown in the figure, and may be the upper side. In this case, it is desirable that the protrusion 8 is provided at a position hidden by the extended portion 60 of the surface decorative material 6.
Further, the protrusion 8 is not limited to a long ridge shape along the longitudinal direction as shown in FIG. 1A, and may be provided with an interval or formed integrally with the substrate 2. However, it may be formed separately and later attached.

In the state where the male real part 4 and the female real part 5 are actually connected, the protruding part 8 has its front end 8a abutted against the abutting side end 3A that is the abutting surface on the flooring 1A side that is disposed next to each other. It is provided so as to form a gap D with the abutting side end 3A by contact (see FIG. 2A).
Accordingly, a gap D (a watermark) having a predetermined size can be provided between the abutting surfaces (the side end portion 3 and the abutting side end portion 3A) of the flooring 1 and the flooring 1A, so that the watermarking construction is easy. Thus, it is possible to cope with a dimensional change due to moisture absorption / release of the substrate 2 made of a wood-based material.
That is, the floor material 1 and the floor material 1A are provided with a gap D of, for example, about 0.2 mm to 0.7 mm, on the premise that the floor material 1 contracts and expands due to moisture absorption / release of the substrate 2 made of a wood-based material. Laying construction of materials 1 and 1A is performed. Therefore, when the female real part 5 is fitted to the male real part 4 until the protruding part 8 comes into contact with the abutting side end 3A during actual coupling, the predetermined gap D is naturally provided. It can be laid (see FIG. 2 (a)).
The protrusion dimension D1 of the protrusion 8 is such that when the floor material 1 is actually coupled to the floor material 1A that is disposed adjacently, the tip 4a of the male part 4 that is formed as a ridge and a female groove that is a groove. It is set so as to be equal to or smaller than the gap dimension D2 between the bottom surface 5a of the real part 5. That is, a relationship of D2 ≧ D1 is established.
The protrusion dimension D1 of the protrusion 8 is a dimension obtained by adding the protrusion dimension of the base 8b of the protrusion 8 and the protrusion dimension of the tip 8a of the protrusion 8.

The tip 8a of the protrusion 8 is formed so as to be buckled by being pressed by the butt end 3A when the substrate 2 expands with moisture.
The configuration of the distal end portion 8a is not particularly limited as long as the distal end portion 8a is configured to buckle (deform) in contact with the abutting side end portion 3A by the pressing force applied by the expansion of the substrate 2. For example, the base 8b of the protrusion 8 may be formed integrally with the substrate 2, and a soft elastic member made of a rubber material, a soft synthetic resin material, a non-woven fabric, or the like may be bonded to the front side thereof with an adhesive. Moreover, as a resin material, it is good also as flexible foam materials, such as foamed polyethylene and a foamed propylene other than a soft plastic. Further, the shape of the distal end portion 8a is not limited to a substantially rectangular shape in a sectional view as shown in the figure, and may be a rounded shape or a triangular shape in a sectional view.
As a result, as shown in FIG. 2B, even if the substrate 2 expands and the gap D dimension is reduced, the tip 8a of the projection 8 is buckled. It can prevent being pushed up.

A resin sheet (film) having flexibility is used for the surface decorative material 6, and the surface decorative material 6 has an extended portion 60 that protrudes from the surface 2 a side of the substrate 2.
In FIG. 1A, the surface decorative material 6 is indicated by a two-dot chain line. In FIG. 1A, the surface decorative material 6 is disposed on the surface 2 a side of the substrate 2, and the peripheral portion protrudes beyond the surface 2 a of the substrate 2. In FIG. 1, the extension portion 60 is actually bent along the inclined surface 2c as shown in FIG.
The surface decorative material 6 may be printed with natural wood grain such as zelkova and cedar, or may be a transparent sheet when a veneer or solid wood is used as the substrate 2.
The surface decorative material 6 has a size that protrudes from the four sides of the surface 2a of the substrate 2, a surface portion 61 adhered to the surface 2a of the substrate 2 via an adhesive layer 7, and a surface that extends further from the surface portion 61. It has the extension part 60 which protruded from the 2a side.
As shown in FIG. 2 (a), the extended portion 60 has a front side 60c of the flooring 1A disposed adjacent to each other in a state where the protruding portion 8 is in contact with the abutting side end portion 3A. The surface decorative material 6 </ b> A is provided so as to be in contact with and bend the front side 60 c of the extending portion 60.
And the front side 60c of this extension part 60 is always in contact with the front side 60c of the extension part 60 in the surface decorative material 6A of the flooring 1A in a state where the flooring materials 1 and 1A are actually connected to each other. It is provided to do.
Thereby, for example, as shown in FIG. 2C, even if the substrate 2 contracts due to drying such as winter, and the gap D between the flooring materials 1, 1 </ b> A increases, Since the front sides 60c and 60c can maintain the contact state, the gap D can be hidden to be inconspicuous.

As shown in FIG. 1B, the extending portion 60 has an adhesive portion 60a attached to the inclined surface 2c of the substrate 2 and a non-adhesive portion 60b extended further ahead of the adhesive portion 60a. doing.
That is, not all of the extended portions 60 are in a non-bonded state, but the corners of the substrate 2 in the illustrated example are chamfered to form an inclined surface 2c. Therefore, the adhesive is applied to the inclined surface 2c. The adhesive layer 7 is provided by coating, and the inclined surface 2c is bonded with an adhesive. Therefore, the extended portion 60 arranged on the inclined surface 2 c is an adhesive portion 60 a, and the front side thereof is a non-adhesive portion 60 b that is separated from the substrate 2.
Thus, since the surface decorative material 6 has the non-adhesion part 60b ahead of the adhesion part 60a stuck to the inclined surface 2c, the extension parts 60 and 60 of the non-adhesion part 60b are turned up at the time of actual joining. It is possible to prevent the tip side 60c, 60c from contacting each other.

Next, the flooring 1, 1A of the present embodiment will be further described with reference to FIG.
FIG. 2A shows a state in which the flooring materials 1 and 1A are neither contracted nor expanded.
In this case, the gap D dimension of the abutting surfaces (the side end 3 and the abutting side end 3A) of the flooring materials 1 and 1A substantially coincides with the protruding dimension D1 of the protrusion 8 and the gap dimension D2.
Further, in this case, the tip 8a of the protrusion 8 is not subjected to a buckling pressing force, and contacts the butting side end 3A (specifically, the lower end surface 30 of the female real part 5). It is assumed that
And in this case, the surface decorative material 6 will be in the state bent so that the front sides 60c and 60c of the extension part 60 may contact, and may enter into the clearance gap D. FIG.

FIG. 2B shows a state where the flooring materials 1 and 1A are inflated. This is likely to happen during wet seasons such as the rainy season.
In this case, the gap D dimension between the abutting surfaces (the side end 3 and the abutting side end 3A) of the flooring materials 1 and 1A is reduced and the interval is narrowed, and the tip 8a of the protrusion 8 is buckled. It is set as the state contact | abutted to 3 A of butt | matching side edge parts (specifically, the lower side end surface 30 of the female real part 5). In addition, the protrusion part 8 shown with the dotted line of FIG.2 (b) has shown the front-end | tip part 8a in the state which is not buckled as an imaginary line.
In this case, the surface decorative material 6 is in a state where the non-bonded portions 60b and 60b and the front sides 60c and 60c of the extending portion 60 are in contact with each other and enter the gap D.

FIG. 2C shows a state where the flooring materials 1 and 1A are contracted. This is likely to happen in dry seasons such as winter.
In this case, the size of the gap D between the abutting surfaces (the side end 3 and the abutting side end 3A) of the flooring materials 1 and 1A is increased, the gap is widened, and the protrusion 8 is also separated from the abutting side end 3A.
Even in this case, the surface decorative material 6 is maintained in a state in which the front sides 60c and 60c of the extending portion 60 are in contact with each other.

  As described above, according to the flooring materials 1 and 1A of the present embodiment, the front sides 60c and 60c of the surface decorative material 6 can always be in contact with each other even if there is a dimensional change due to moisture absorption and desorption of the substrate 2. Therefore, the gap D between the flooring materials 1 and 1A can be prevented from being seen, and the appearance is good. In addition, it is possible to prevent dust or dust from entering the gap D.

  The shapes and configurations of the flooring 1, the substrate 2, the surface decorative material 6 and the like described in the above embodiment are not limited to the above examples. For example, the flooring 1 may have a real part formed only at opposite side ends. Since the floor materials 1 and 1A of the present embodiment are watermarked, the upper surface of the protrusion of the male part 4 is the same color as the surface of the floor material 1, that is, the surface decorative material 6 or the substrate 2 depending on the case. May be colored. According to this, even when the substrate 2 contracts more than expected and the gap D is vacant, the gap D can be made inconspicuous.
