Description

[Technical Field]

[0001] This invention relates to a baseboard that can be firmly bonded to any material using conventional wood glue. [Background technology]

[0002] A baseboard is a long, thin piece of material that is attached to the corners of a floor and a wall to close any gaps that may occur between them, and is installed around the perimeter of a room. Baseboards are also installed on stairs in a room. Incidentally, most conventional baseboards are made of wood, and workers can glue them using wood glue, but there are cases where workers do not have glue to glue plastic baseboards. However, workers may inadvertently apply wood glue to adhere the resin baseboard, which may not be completely fixed and may peel off at a later date.

[0003] Figure 5(a) shows the cross section of a conventional wooden baseboard (A), with a nail groove (C) of a constant width extending longitudinally on the front surface (B), and two parallel grooves (E), (E) extending longitudinally on the back surface (D). The grooves (E) have a trapezoidal cross section, being wider at the entrance and narrower at the back. Figure 5(b) is also a cross section of a conventional wooden baseboard (a), which has nail grooves (c) on the front surface (b) and a recessed groove (f) on the back surface (d) that has a rectangular cross section.

[0004] The surface of the wooden baseboard (A) is covered with a wood grain or solid color film to enhance the design. In addition, if water spills and adheres to the baseboard, the expansion of the baseboard can be suppressed even if water droplets adhere to the surface due to condensation. In contrast, resin baseboards have a high design quality even without a film attached to the surface, and are water-resistant, so there is no problem even if water droplets adhere to the surface.

[0005] The baseboard (a) above is attached to the wall by pouring adhesive onto the backside, and this state is shown in Figures 6 and 7. Figure 6 shows the case where the cross section of the groove (E) is trapezoidal, (a) shows the case where the bond (G) is applied longitudinally to the center of the back surface of the baseboard (D), and (b) shows the case where the baseboard (A) is glued to a wall. When attached to a wall, the gap (H) between the wall surface and the floor is filled, and the bond (G) spreads over the entire back surface, flows into both grooves (E), (E), and then hardens. Here, since it takes time for the bond (T) to harden and the baseboard (I) to be fixed, the baseboard (I) attached to the wall surface is temporarily fixed in place by driving a tacker needle (R) into the nail groove (C).

[0006] Figure 7 shows the case where a baseboard (I) with a rectangular cross-section groove (F) is glued to a wall surface. (a) shows the case where glue (T) is applied to the back side (D), and (b) shows the case where the baseboard (I) is attached to the wall surface and temporarily secured with a stapler needle (Ri). In this way, wooden baseboards (I) are glued and fixed to the wall using wood glue, but even in the case of plastic baseboards, workers may carelessly use wood glue (C) to glue them down, and if wood glue (T) is used, the baseboard (I) will peel off even after hardening.

[0007] The "vinyl chloride resin baseboard" disclosed in JP 2002-155150 A is a vinyl chloride resin baseboard that is easy to install, prevents shrinkage and adhesive peeling after installation, and can suppress the generation of hydrogen chloride gas during combustion, such as in fires, combustion treatment, and thermal recycling. This polyvinyl chloride resin baseboard is formed integrally with a surface layer made of 0 to 70 parts by weight of calcium carbonate and 10 to 110 parts by weight of plasticizer per 100 parts by weight of polyvinyl chloride resin, and a base layer made of 150 to 250 parts by weight of calcium carbonate and 30 to 70 parts by weight of plasticizer per 100 parts by weight of polyvinyl chloride resin, in which the calcium carbonate has a pore distribution in the interval between 6.0×102 and 1.0×106 Å of 70 to 100% and a pore distribution in the interval between 6.0×102 and 3.7×103 Å of 11 to 20% in a pore distribution graph obtained by a mercury intrusion porosimeter.

[0008] The "construction material installation method" according to JP 2002-97773 A is an installation method that does not require other members such as temporary nails or holding plates to fasten construction materials together. In a method for fixing a baseboard to a wall of a house, an instant adhesive is applied to a plurality of locations on the adhesive surface of the baseboard, and a general adhesive having a longer hardening time than the instant adhesive is applied to a plurality of locations at intervals from the applied locations, so that the instant adhesive serves as an auxiliary adhesive until the general adhesive hardens. [Patent Document 1] "Vinyl chloride resin baseboard" according to JP 2002-155150 [Patent Document 2] "Construction material application method" according to JP 2002-97773 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0009] The problem with baseboards, which are installed at the corners of the floor and wall to close the gap between them, is as described above. Also, as described in the above patent document, it is possible to install resin baseboards, but the purpose of this invention is different. To provide a baseboard that can be firmly and stably bonded by applying a general bond, regardless of whether the baseboard is made of wood, resin, or other materials. [Means for solving the problem]

[0010] The baseboard of this invention is constructed so that it can be firmly adhered so that it will not peel off by applying a conventional, general adhesive to the backside. Whether the baseboard is made of wood, resin, or some other material, the baseboard is firmly connected to the wall surface via a hardening bond so that it will not peel off from the wall surface.

[0011] The back surface of the baseboard to which the adhesive is applied is formed with a groove into which the adhesive flows, and the cross-sectional shape of the groove is such that the width at the back is greater than the width at the entrance. However, the specific cross-sectional shape of the groove is not limited, and the number of grooves is also free. For example, by making the cross section into an inverted trapezoid, the width dimension at the back is larger than the width dimension at the entrance, and the baseboard will not come off the hardened bond layer. [Effects of the Invention]

[0012] The baseboard of this invention has a groove on the backside, and the cross-sectional shape of the groove is wider at the back than at the entrance, so when the baseboard is attached to a wall, the adhesive applied to the backside of the baseboard flows into the groove and fills it. When the bond has hardened, it will not slip out of the recessed groove with a narrow entrance width, and the baseboard will be firmly and stably fixed to the wall surface of the room via the hardened bond. The baseboard material is not limited, and as long as the cross section of the groove on the back side is wider at the back than at the entrance, it can be fixed in place using a bond that is filled and hardened.

[0014] FIG. 1 shows an embodiment of a baseboard 1 according to the present invention, which is a long piece of material having a predetermined cross section and extending in the longitudinal direction. The baseboard 1 shown in the figure has a roughly rectangular cross section and has a surface 2, a back surface 3, a top surface 4, and a bottom surface 5. Various patterns are formed on the surface 2 and top surface 4, and a nail groove 6 extending longitudinally is provided in the center of the surface 2. The corners of the surface 2 and top surface 4 are also notched. The material of the baseboard 1 is not limited, and it can be made of resin, wood, or sometimes aluminum.

[0015] The baseboard 1 is adhered to the wall with its bottom surface 5 placed on the floor of the room, and for this purpose a bond as an adhesive is applied to the back surface, and the applied bond spreads evenly over the entire back surface and flows into the recessed groove 7 formed on the back surface. 2, the groove 7 is inverted trapezoidal, with the width B at the back being larger than the width A at the entrance. Therefore, once the bond that flows into the groove 7 hardens, the solidified bond will not come out of the groove 7. In other words, the baseboard 1 is fixed in place within the groove 7 via the hardened bond.

[0016] The baseboard 1 shown in FIG. 1( a ) has one groove 7 formed in the upper part of the back surface 3 , and the baseboard 1 shown in FIG. 1( b ) has two grooves 7 , 7 formed in the back surface 3 . Figure 3 shows the case of attaching the skirting board 1 according to the present invention. As shown in (a), bond 8, which is an adhesive, is applied along the longitudinal direction at the central part of the back surface 3 of the skirting board 1. The skirting board 1 to which the bond 8 is applied is placed on the floor surface with the bottom surface 5 and abutted against the wall surface with the back surface 3 to be bonded. By bonding the skirting board 1, the gap 9 formed between the wall surface and the floor surface is blocked.

[0017] By the way, the bond 8 applied to the central part of the back surface 3 spreads and flows into the concave grooves 7, 7 when the skirting board 1 is attached to the wall surface, and the concave grooves 7, 7 are filled with the bond 8. The bond 8 that spreads on the back surface 3 and is filled in the concave grooves 7, 7 hardens over time, and the skirting board 1 is adhered and fixed to the wall surface. For the skirting board 1 with the bond 8 applied to the back surface 3 and bonded to the wall surface, a tacker pin 10 is driven in from the nail groove 6 as shown in Fig. 3(b) for temporary fixing while the bond 8 hardens.

[0018] Thus, the skirting board 1 of the present invention is fixed to the wall surface through the bond 8 filled and hardened in the concave groove 7 by making the cross-sectional shape of the concave groove 7 formed on the back surface 3 such that A < B, and does not peel off. By the way, the cross-sectional shape of the concave groove 7 is not limited to the trapezoid shown in Fig. 2 above, and the concave groove 7 can have various cross-sectional shapes as shown in Fig. 4.

[0019] Fig. 4(a) shows the concave groove 7 with a trapezoidal cross-section shown in Fig. 1 above, where the width dimension A on the entrance side < the width dimension B on the inner side. Fig.​​​​​​​The bond 8 filled and hardened in the grooves 11, 12 cannot be pulled out of the grooves 11, 12 even if it is pulled toward the rear surface 3. In other words, the width dimension on the entrance side needs to be smaller than the width dimension on the back side, and the cross-sectional shape is not limited to the inverted trapezoid, circle, and T-shape shown in the embodiments. On the other hand, the baseboard 1 of this invention is generally installed at the corner between the wall and floor of a room, but it can also be applied to an L-shaped baseboard for stairs that is installed from the tread to the riser of a staircase.
