BACKGROUND OF THE INVENTION
The present invention is arranged at a boundary portion between a wall surface and a floor surface, and a baseboard body fixed to the wall surface, and a non-land adjustment member positioned below the baseboard body and fixed to the floor surface. The present invention relates to a baseboard that is excellent in ability to close a gap that can be formed between the floor surface and a contact surface between the wall surface and the floor surface and that can improve the workability of construction.
[0002]
[Prior art]
Conventionally, as this type of baseboard, for example, one having a structure disclosed in Japanese Patent Application Laid-Open No. 10-88779 is known. FIG. 9 is a schematic sectional view showing the structure of an example of this conventional baseboard.
In FIG. 9A, reference numeral 31 is a baseboard. The baseboard 31 includes a baseboard body 32 fixed to the wall surface 20, and a non-land adjustment member 33 positioned below the baseboard body 32 and fixed to the floor surface 21.
The uneven adjustment member 33 has an upward fitting protrusion 34 on the wall surface side of the upper surface thereof. The baseboard 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, on the surface side between the baseboard body 32 and the uneven adjustment member 33. A joint 36 appears.
[0003]
Here, when a joist (not shown) that supports the floor surface 21 from below is dried and contracted, the floor surface 21 is subsidized or uneven. On the other hand, since the wall surface 20 is fixed to an outer wall or the like (not shown), a gap 22 is generated on the contact surface between the wall surface 20 and the floor surface 21. At this time, as shown in FIG. 9B, the baseboard main body 32 and the unevenness adjusting member 33 slide in the direction of separating from each other up and down and work to close the gap 22. At this time, the width of the joint 36 varies.
[0004]
[Problems to be solved by the invention]
In the baseboard 31 having the above-described structure, since the baseboard 31 is composed of two members, the baseboard body 32 and the non-land adjustment member 33, the base plate 31 is dimensioned and positioned by using the non-land adjustment member 33. It was necessary to carry out after temporarily fixing to the floor surface 21 and then placing the baseboard body 32 on the unevenness adjusting member 33. Further, in order to cut the baseboard 31 to a predetermined size, it is necessary to cut the baseboard body 32 and the unevenness adjusting member 33 separately. Furthermore, in order to install the baseboard 31, it is necessary to fix the unevenness adjusting member 33 on the floor 21 and then fix the baseboard body 32 on the unevenness adjusting member 33. As described above, the conventional baseboard is easy to be constructed.
[0005]
Moreover, when partial unevenness or subsidence occurs on the floor surface 21 due to secular change, the subsidence amount of the floor surface 21 is not uniform, so that the widths of the joints 36 are uneven and the appearance is poor.
Therefore, the problem of the present invention is that it has an excellent ability to close a gap that can be formed on the contact surface between the wall surface and the floor surface, the workability of the construction is improved, a joint is not required, and the floor surface is partially damaged. The object is to provide a baseboard that does not impair the aesthetics even if land or subsidence occurs.
[0006]
[Means for Solving the Problems]
The subject is a baseboard that is fixed to a wall surface, and a baseboard that is positioned below the baseboard body and that is fixed to a floor surface. A fitting ridge along the longitudinal direction of the baseboard is vertically provided, and the fitting ridge has a thickness at a tip portion larger than a thickness at a root portion, and the unevenness adjusting member A fitting groove into which the fitting protrusion can be fitted is provided on the upper surface of the fitting groove, and the cross-sectional shape of the fitting groove includes the shape of the cross-section of the fitting protrusion, and the fitting The mating ridge is solved by a baseboard adapted to be fitted in the fitting groove.
[0007]
In order to be able to nail and fix the unevenness adjusting member to the floor surface with the baseboard body and the unevenness adjusting member fitted, the upper end surface of the side wall on the surface side of the fitting groove of the unevenness adjusting member is And having a width sufficient to drive a nail for fixing the unevenness adjusting member to the floor surface, and the upper end surface of the side wall on the surface side is parallel to the floor surface or from the back side It is inclined downward toward the surface side, and the angle formed between the upper end surface of the side wall on the surface side and the floor surface is 0 to 45 °.
[0008]
Since the baseboard body and the unevenness adjusting member can slide smoothly, the side surface on the surface side of the fitting ridge of the baseboard body is a plane parallel to the wall surface, and the fitting The side surface on the back side of the mating ridge is preferably provided with a gradient so that the thickness of the tip of the fitting ridge is greater than the thickness of the root portion.
[0009]
Furthermore, the sum of the maximum thickness of the fitting protrusion of the baseboard body and the maximum thickness of the side wall on the back side of the fitting groove of the uneven adjustment member is the wall surface and the fitting protrusion. If the distance is less than or equal to the distance from the side surface on the front side of the strip, a sufficient gap can be obtained between the wall surface and the side wall on the back side of the fitting groove of the non-land adjustment member. The side wall on the back side of the joint groove can be easily elastically deformed so as to avoid the fitting protrusion of the baseboard body, and the baseboard body and the unevenness adjusting member can slide more smoothly.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on embodiments with reference to the drawings. FIG. 1 is a perspective view showing an example of the baseboard of the present invention. In FIG. 1, reference numeral 1 is a baseboard. The baseboard 1 is formed by fitting a baseboard body 2 fixed to a wall surface 20 and an unevenness adjusting member 3 positioned below the baseboard body 2 and fixed to a floor surface 21.
[0011]
In the skirting board 1 of the present invention, a fitting ridge 4 is vertically provided along the longitudinal direction of the skirting board 1 as shown in FIG. Further, the fitting protrusion 4 has a thickness D ₂ at the tip portion larger than a thickness D ₁ at the base portion, and the base board body 2 and the unevenness adjusting member 3 are fitted to each other. It is designed to be used as a stopper when letting go.
[0012]
In order for this retainer to function properly, the difference (D ₂ −D ₁ ) obtained by subtracting D ₁ from D ₂ is preferably in the range of 0.1 to 0.3 mm. When 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 when it exceeds 0.3 mm, the baseboard body 2 and the uneven adjustment member 3 The baseboard 2 and the unevenness adjusting member 3 are difficult to slide in a direction away from each other when the mating is hard and the floor surface is lowered or uneven, which is not preferable. .
[0013]
The height H of the fitting protrusion 4 is preferably 3 mm or more. When the height H of the fitting ridge 4 is less than 3 mm, even if the fitting ridge 4 is fitted in the fitting groove 5, the skirting board body 2 easily falls down during construction and the floor 21 When the amount of descent is large, it cannot be handled by the slide of the baseboard, which is not preferable.
The upper limit value 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 descent of the floor surface 21 to be handled.
[0014]
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 front end portion of the fitting groove 5 and the side surfaces on both sides of the root portion of the fitting protrusion 4 are aligned with each other. 5 to be sandwiched. For this reason, the baseboard main body 2 and the unevenness adjusting member 3 are fitted without being removed.
Between the bottom part of the fitting groove 5 and the tip part of the fitting protrusion 4, a margin may be given due to molding tolerances, or the cross-sectional shapes may be matched to each other also in this part. .
For this reason, since the skirting board 1 can be conveyed, cut | disconnected, and installed in the state which the baseboard main body 2 and the unevenness adjustment member 3 were mutually fitted, the workability | operativity of construction is improved.
[0015]
Furthermore, as shown in FIG. 4, the upper end surface of the side wall 5 a on the surface side of the fitting groove 5 has a width sufficient to drive a nail 10 for fixing the unevenness adjusting member 3 to the floor surface 21. Preferably there is. As a result, in the state in which the baseboard body 2 and the unevenness adjusting member 3 are fitted, the unevenness adjusting member 3 can be nail-fixed to the floor surface 21, and the workability of construction is improved.
The width W of the upper end surface of the side wall 5a on the surface side of the fitting groove 5 is preferably 2 to 8 mm. If the width W is less than 2 mm, it is not sufficient for driving a nail, and if it exceeds 8 mm, it is unnecessarily wide, which is not preferable in design.
[0016]
As described above, when the upper end surface of the side wall 5a on the surface side of the fitting groove 5 is used as a nail driving surface, it is easy to fix the nail using a nail driver or the like. The upper end surface of the side wall 5a on the front side is parallel to the floor surface 21 or is inclined downward from the back side toward the front side, and the upper end surface of the side wall 5a on the front side of the fitting groove 5 The angle θ formed with the floor surface 21 is in the range of 0 to 45 °.
[0017]
Furthermore, it is preferable that the side surface on the surface side of the fitting protrusion 4 is a plane parallel to the wall surface 20 as shown in FIG. As a result, as shown in FIG. 5 (b), the floor surface 21 is lowered, and a gap 22 is formed in the contact surface between the wall surface 20 and the floor surface 21, and the baseboard body 2 and the unevenness adjusting member 3 are When sliding up and down apart from each other, no joints are formed between the baseboard body 2 and the unevenness adjusting member 3, so that the aesthetic appearance is not impaired.
[0018]
If the side surface on the front surface side of the fitting protrusion 4 is located above the inner surface of the side wall 5a on the front surface side of the fitting groove 5, the baseboard body 2 and the unevenness adjusting member 3 are vertically moved. When sliding so as to be separated from each other, as shown in FIG. 6A, the joint 6 appears between the baseboard body 2 and the unevenness adjusting member 3, which may impair the aesthetic appearance.
[0019]
Further, if the side surface on the front surface side of the fitting protrusion 4 is located below the inner surface of the side wall 5a on the front surface side of the fitting groove 5, the baseboard body 2 and the unevenness adjusting member 3 are When trying to slide vertically apart from each other, as shown in FIG. 6B, the side surface on the surface side of the fitting protrusion 4 and the inner surface of the side wall 5 a on the surface side of the fitting groove 5 In addition, a drag force resisting the slide is generated, and the side wall 5a on the surface side is fixed by the nail 10 and has increased rigidity, so that the slide becomes difficult.
[0020]
Therefore, it is preferable that the side surface on the surface side of the fitting protrusion 4 is a plane parallel to the wall surface 20 as shown in FIG.
In the present invention, the fact that the side surface on the surface side of the fitting protrusion 4 is parallel to the wall surface 20 does not mean that it must be strictly parallel, but to the extent that the above-mentioned problem does not become practically significant. An error is allowed. The range of this error is within ± 0.5 °.
[0021]
As described above, since the thickness D ₂ of the tip portion is larger than the thickness D _{1 of the} root portion of the fitting ridge 4, the side surface on the surface side of the fitting ridge 4 is the wall surface 20. Therefore, the side surface on the back side of the fitting protrusion 4 is given a gradient so that the thickness of the tip portion is larger than the thickness of the root portion. There is a need.
[0022]
Furthermore, the sum of the maximum value A of the thickness of the fitting protrusion 4 of the baseboard body 2 and the maximum value B of the thickness of the side wall 5b on the back side of the fitting groove 5 of the unevenness adjusting member 3 is It is preferable that the distance 20 be equal to or less than the distance C between the wall surface 20 and the side surface on the 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 protrusion 4 is designed to be prevented from coming off, when the baseboard body 2 and the unevenness adjusting member 3 try to slide in a direction in which they are spaced apart from each other, they are fitted. A drag force that resists sliding is generated between the side surface of the mating protrusion 4 and the inner surface of the fitting groove 5.
[0023]
By forming the unevenness adjusting member 3 in the above-described shape, the side wall 5b on the back side of the fitting groove 5 is elastic in the direction of 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 deformation is obtained, the side wall 5b on the back side of the fitting groove 5 is elastically deformed in the direction of the wall surface 20, whereby the drag force resisting the slide can be reduced.
[0024]
In order to satisfy the relationship of A + B ≦ C, as shown in FIG. 5A, a gradient is given to the side surface on the back side of the side wall 5b on the back side of the fitting groove 5 of the unevenness adjusting member 3, so that the room 7 may occur, or as shown in FIG. 7, the entire rear side surface of the unevenness adjusting member 3 may be separated from the wall surface 20.
[0025]
The maximum value B of the 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 easy to bend and the fitting is easy to loosen, which is not preferable. On the other hand, if it exceeds 3 mm, the side wall 5b on the back side of the fitting groove 5 is difficult to elastically deform in the direction of the wall surface 20, which is not preferable.
[0026]
The baseboard 1 of the present invention is not necessarily the one illustrated in the above drawings as long as it has a shape having the characteristics described above. For example, in the above-described example, as shown in FIG. 2, the baseboard body 2 is provided with a nail driving groove 8 along the longitudinal direction of the baseboard 1 for the convenience and design of nailing, Moreover, in order to improve the shock absorption, the hollow portion 9 is provided inside, but these structures are not necessarily required, and may be provided or omitted depending on the purpose. Needless to say.
[0027]
The surface in contact with the wall surface 20 of the baseboard body 2 or the surface in contact with the floor surface 21 of the unevenness adjusting member 3 can be roughened to facilitate sticking with an adhesive.
The design can be enhanced by applying a pattern to the surface side of the baseboard 1 with a hot stamp or the like.
When furniture is pressed against the skirting board 1, the furniture may be stably installed, so that the contact surface may be aligned between the skirting board main body 2 and the unevenness adjusting member 3.
[0028]
As a material used for the baseboard 1 of the present invention, plastic, MDF (medium density fiberboard), plywood and the like can be used. In particular, a resin material (E-ABS) obtained by mixing foamable ABS and wood powder is particularly suitable because it has a texture close to that of natural wood and is excellent in machinability.
[0029]
The construction of the baseboard 1 of the present invention can be performed by the following procedure, for example. FIG. 8 is a schematic cross-sectional view showing an example of a state in which the baseboard 1 of the present invention is installed.
First, the baseboard 1 is positioned and dimensioned at the corner between the wall surface 20 and the floor surface 21. Next, the baseboard 1 is cut into a predetermined dimension. Next, the adhesive 12 is applied to the back surface of the baseboard body 2. Next, the baseboard 1 is installed so that the back surface of the baseboard body 2 is in contact with the wall surface 20 and the bottom surface of the unevenness adjusting member 3 is in contact with the floor surface 21. After the adhesive 12 is cured, 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]
【The invention's effect】
As described above, the baseboard of the present invention is configured such that the baseboard body and the non-land adjustment member can be fitted without being removed, and the floor surface is lowered or uneven. In addition, since the baseboard body and the unevenness adjusting member can be smoothly slid in the vertical direction away from each other, it is excellent in the ability to close the gap that may occur on the contact surface between the wall surface and the floor surface. At the same time, conveyance, cutting, and installation are possible in a state where the baseboard body and the unevenness adjusting member are fitted to each other, and the workability of construction is improved.
In addition, since it is not necessary to provide a joint between the baseboard body and the unevenness adjusting member, even if partial unevenness or subsidence occurs on the floor surface 21, there is no possibility of deteriorating the aesthetic appearance.
