2. Description of the Related Art Conventionally, as this kind of skirting board, for example,
The structure disclosed in Japanese Patent Laid-Open No. 10-88779 is known. FIG. 9 is a schematic sectional view showing the structure of an example of this conventional skirting board. In FIG. 9A, reference numeral 3
1 is a skirting board. The skirting board 31 is located below the skirting board body 32 and the skirting board body 32 fixed to the wall surface 20,
It comprises a non-adjustment member 33 fixed to the floor surface 21. The unevenness adjusting member 33 has an upward fitting protrusion 34 on the wall surface side of the upper surface thereof. Further, the baseboard main body 32 has a downward fitting groove 35 for fitting the fitting protrusion 34 on the lower surface thereof. Here, the height of the fitting protrusion 34 is set to be larger than the depth of the fitting groove 35, and in the fitted state, the skirting board main body 32 and the unevenness adjusting member 33.
The joint 36 is formed on the surface side between and.

Here, when the joists (not shown) that support the floor surface 21 from below are dried and contracted, the floor surface 21 is sunk or unsteady. On the other hand, since the wall surface 20 is fixed to an outer wall or the like (not shown), a gap 2 is formed on the contact surface between the wall surface 20 and the floor surface 21.

[0006]

Means for Solving the Problems The above-mentioned problem is in a skirting board comprising a skirting board main body fixed to a wall surface and an inland adjusting member which is located below the skirting board main body and fixed to the floor surface. At the front end of the lower surface of the baseboard main body, a fitting ridge extending vertically in the longitudinal direction of the baseboard is provided, and the fitting ridge is such that the wall thickness of the tip is larger than the wall thickness of the root. And a fitting groove into which the fitting projection can be fitted is provided on the upper surface of the uneven adjustment member, and the shape of the cross section of the fitting groove is the same as the shape of the cross section of the fitting projection. It is included and is solved by a skirting board, wherein the fitting ridge is adapted to be fitted in the fitting groove.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below in detail based on embodiments with reference to the drawings. Figure 1
It is a perspective view showing an example of a skirting board of the present invention. In FIG. 1, reference numeral 1 is a skirting board. The skirting board 1 is formed by fitting a skirting board body 2 fixed to a wall surface 20 and an unsteady adjusting member 3 located below the skirting board body 2 and fixed to a floor surface 21.

In the skirting board 1 of the present invention, as shown in FIG. 2, a fitting projection 4 is vertically provided at the front end of the lower surface of the skirting board body 2 along the longitudinal direction of the skirting board 1. . The fitting protrusion 4 has a wall thickness D ₂ at the tip end that is larger than the wall thickness D ₁ at the root part, so that the skirting board main body 2 and the unevenness adjusting member 3 are fitted together. It is designed to prevent it from coming off when it is made.

In order for this retainer to function properly,
The difference from the D ₂ by subtracting the D ₁ (D ₂ -D ₁₎ is 0.1 to 0.3
It is preferably in the range of mm. If the value of D ₂ -D ₁ is less than 0.1 mm, the fitting protrusion 4 easily comes off from the fitting groove 5, and if it exceeds 0.3 mm, the baseboard main body 2
When the fitting between the base and the unevenness adjusting member 3 becomes hard and the floor surface is lowered and unevenness occurs, the baseboard body 2 and the unevenness adjusting member 3 are
It is not preferable because it becomes difficult to slide in the directions away from each other.

The height H of the fitting protrusion 4 is preferably 3 mm or more. If the height H of the fitting protrusion 4 is less than 3 mm,
Even if the fitting ridge 4 fits in the fitting groove 5, the skirting board main body 2 is likely to fall out during construction and the floor surface 21 is largely descended. This is not preferable because it will not be possible. The upper limit of the height H of the fitting protrusion 4 is not particularly limited, but is preferably 20 mm or less in consideration of the maximum value of the amount of fall of the floor surface 21 to be dealt with.

As shown in FIG. 3, a fitting groove 5 is provided on the upper surface of the unevenness adjusting member 3 so as to face upward. The cross-sectional shape of the fitting groove 5 includes the cross-sectional shape of the fitting protrusion 4. That is, at least the side surfaces on both sides of the tip of the fitting groove 5 and the side surfaces on both sides of the root of the fitting protrusion 4 are aligned with each other. It is designed to be sandwiched between 5. Therefore, the baseboard main body 2 and the unevenness adjusting member 3 can be fitted to each other without being pulled out. The bottom of the fitting groove 5 and the fitting projection 4
A margin may be provided between the tip end portion and the tip end portion due to molding tolerances, or the cross-sectional shapes may be matched with each other at this portion as well. Therefore, the skirting board 1 is in a state in which the skirting board body 2 and the unevenness adjusting member 3 are fitted to each other,
Since it can be transported, cut, and installed, workability of construction can be improved.

Further, as shown in FIG. 4, the upper end surface of the side wall 5a on the front surface side of the fitting groove 5 has a width sufficient to drive the nail 10 for fixing the unevenness adjusting member 3 to the floor surface 21. It is preferable to have one. As a result, the baseboard body 2
With the unsteady adjusting member 3 fitted, the unsteady adjusting member 3
Can be nailed and fixed to the floor surface 21, and the workability of construction can be improved. Side wall 5 on the surface side of the fitting groove 5
The width W of the upper end surface of a is preferably 2 to 8 mm.
If the width W is less than 2 mm, it is not enough to drive a nail, and if it exceeds 8 mm, it is unnecessarily wide, which is not preferable in terms of design.

Thus, the side wall 5a on the front surface side of the fitting groove 5 is formed.
When the upper end face of the fitting groove 5 is used as the nailing surface, the upper end surface of the side wall 5a on the surface side of the fitting groove 5 is located on the floor surface 21 because the nailing fixing using a nailing machine or the like is easy. They are parallel to each other or are inclined downward from the back side to the front side, and an angle θ formed by the upper end surface of the side wall 5a on the front side of the fitting groove 5 and the floor surface 21 is 0 to 45 °. Within the range of.

Furthermore, it is preferable that the side surface on the front surface side of the fitting projection 4 is a flat surface parallel to the wall surface 20, as shown in FIG. 5 (a). As a result, FIG.
As shown in (b), the floor surface 21 descends, a gap 22 is formed in the contact surface between the wall surface 20 and the floor surface 21, and the skirting board body 2 and the unevenness adjusting member 3 are vertically separated from each other. When sliding like this, since no joint is formed between the baseboard main body 2 and the unevenness adjusting member 3, the appearance is not spoiled.

When the side surface of the fitting protrusion 4 on the front surface side is located higher than the inner surface of the side wall 5a on the front surface side of the fitting groove 5, the skirting board body 2 and the unevenness adjusting member 3 are formed. When the two slide up and down so as to be separated from each other, as shown in FIG. 6A, the joint 6 appears between the baseboard main body 2 and the unsteady adjusting member 3, which may impair the aesthetic appearance.

If the side surface of the fitting ridge 4 on the surface side is located below the inner side surface of the side wall 5a on the surface side of the fitting groove 5, the baseboard body 2 and the unevenness adjusting member. 6 and 3 are trying to slide vertically apart from each other,
As shown in (b), a reaction force that resists sliding is generated between the side surface of the fitting protrusion 4 on the front surface side and the inner surface of the side wall 5a on the front surface side of the fitting groove 5, and Since the side wall 5a on the front surface side is fixed by the nail 10 and has increased rigidity, sliding becomes difficult.

Therefore, it is preferable that the side surface of the fitting projection 4 on the surface side is a plane parallel to the wall surface 20 as shown in FIG. 5 (a). In the present invention, the fact that the side surface on the front surface side of the fitting projection 4 is parallel to the wall surface 20 does not mean that it must be strictly parallel, and the above-mentioned problems do not become noticeable in practice. It allows an error. The range of this error is ± 0.5 °
Within.

As described above, the fitting projection 4 has the wall thickness D ₂ at the tip end portion larger than the wall thickness D _{1 at the} root portion.
Since the side surface on the front surface side of the fitting protrusion 4 is formed into a plane parallel to the wall surface 20, the side surface on the back side of the fitting protrusion 4 has a wall thickness of the tip portion at the root portion. It must be graded so that it is greater than the thickness.

Further, the sum of the maximum value A of the wall thickness of the fitting projection 4 of the skirting board body 2 and the maximum value B of the wall thickness of the side wall 5b on the back side of the fitting groove 5 of the unevenness adjusting member 3. However, it is preferable that the distance C is less than or equal to the distance C between the wall surface 20 and the side surface on the front surface side of the fitting protrusion 4. The reason why the unevenness adjusting member 3 has such a shape is as follows. As described above, since the fitting projection 4 is designed to prevent the fitting from coming off, when the skirting board main body 2 and the unsteadiness adjusting member 3 try to slide in the directions in which they are vertically separated from each other, they are fitted. A reaction force that resists sliding is generated between the side surface of the mating ridge 4 and the inner side surface of the fitting groove 5.

By forming the unevenness adjusting member 3 into the above-described shape, the side wall 5b on the back side of the fitting groove 5 has the wall surface 20 between the side wall 5b on the back side of the fitting groove 5 and the wall surface 20. Since the room 7 for elastically deforming in the direction is obtained, the side wall 5b on the back side of the fitting groove 5 elastically deforms in the direction of the wall surface 20 to reduce the drag force that resists sliding.

In order to satisfy the relation of A + B ≦ C,
As shown in FIG. 5 (a), the side surface on the back side of the side wall 5 b on the back side of the fitting groove 5 of the unevenness adjusting member 3 may be provided with a gradient so that the room 7 is generated. As shown in FIG. 7, the entire back side surface of the unevenness adjusting member 3 may be separated from the wall surface 20.

The maximum value B of the wall thickness of the side wall 5b on the back side of the fitting groove 5 is preferably in the range of 1 to 3 mm. If this value is less than 1 mm, the side wall 5b on the back side of the fitting groove 5 is easily bent, and the fitting is easily loosened, which is not preferable. Further, when it exceeds 3 mm, the side wall 5 on the back side of the fitting groove 5
This is not preferable because it becomes difficult for b to elastically deform in the direction of the wall surface 20.

The baseboard 1 of the present invention does not necessarily have to be the one illustrated in the above drawings as long as it has a shape having the characteristics described above. For example, in the above-mentioned example, as shown in FIG. 2, the skirting board main body 2 is provided with a nailing groove 8 along the longitudinal direction of the skirting board 1 for convenience of nailing and design. Further, the hollow portion 9 is provided inside in order to enhance shock absorption, but these structures are not always necessary, and may be provided or omitted depending on the purpose. Needless to say.

The surface of the baseboard body 2 in contact with the wall surface 20 or the surface of the unevenness adjusting member 3 in contact with the floor surface 21 can be roughened in order to facilitate attachment with an adhesive.
The designability can be improved by providing a pattern on the surface side of the baseboard 1 with a hot stamp or the like. Since the furniture can be installed stably when the furniture is pressed against the skirting board 1, the skirting body 2 and the unevenness adjusting member 3
The contact surfaces may be aligned.

The material used for the baseboard 1 of the present invention may be plastic, MDF (medium density fiberboard), plywood, or the like. In particular, the resin material (E-ABS) obtained by mixing the foamable ABS and the wood powder has a texture close to that of natural wood and is excellent in machinability, and thus is particularly preferable.

The baseboard 1 of the present invention can be constructed, for example, by the following procedure. FIG. 8 shows a baseboard 1 according to the present invention.
It is a schematic sectional drawing which shows an example of the state in which was installed. First of all, at the corner between the wall surface 20 and the floor surface 21,
Position and size. Next, the skirting board 1 is cut into a predetermined size. Next, the adhesive 12 is applied to the back surface of the baseboard body 2. Next, the skirting board 1 is installed so that the back surface of the skirting board body 2 contacts the wall surface 20 and the bottom surface of the unevenness adjusting member 3 contacts the floor surface 21. After the adhesive 12 is hardened, the baseboard body 2 is fixed to the wall surface 20 and the unevenness adjusting member 3 is fixed to the floor surface 21 with nails 10 and 11, respectively.

[0030]

As described above, the baseboard of the present invention is
The baseboard main body and the unevenness adjusting member can be fitted together without being removed, and even if the baseboard main body and the unevenness adjusting member move up and down even if the floor surface descends or becomes uneven. Since it can slide smoothly in the direction of separating from each other, it has an excellent ability to close the gap that may occur in the contact surface between the wall surface and the floor surface, and also fits the skirting board body and the unsteady adjustment member. It can be transported, cut, and installed in the combined state, improving workability of construction. Moreover, since it is not necessary to provide a joint between the baseboard body and the unevenness adjusting member, the floor surface 21
There is no risk of spoiling the aesthetics even if partial unsteadiness or subsidence occurs.
