Description

[Technical Field]

[0001] This invention relates to corner caps for baseboard corners that can be firmly attached 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] By the way, the baseboards installed around the perimeter of a room have corners, and corner caps are attached to the protruding corners. The corner caps attached to the protruding corners are also glued with wood glue, but just like the baseboards, they are not completely fixed, so they will fall off later.

[0004] Usually, when attaching wooden baseboards to a wall, wood glue is applied to the backside of the baseboard, and the wood glue spreads over the entire backside of the baseboard. Sometimes, if the applied wood glue spills over the baseboard, it is wiped off with a rag or similar, and the applied wood glue also penetrates fully into the glue reservoir groove on the backside. Since wood glue does not dry quickly, staples are driven into the nail grooves to temporarily secure the baseboard in place so that it does not lift up. The applied wood glue will harden in about 24 hours, at which point the baseboard will be glued to the wall.

[0005] When installing baseboards, corner caps are attached to the inside and outside corners of the baseboard, but these corner caps are usually made of resin and can easily fall off even when attached using wood glue. Figure 7 shows a baseboard (A) and the baseboard (A) attached to a wall surface (B), where (a) is the back surface (C) of the baseboard (A), which has a narrow glue reservoir groove (D) extending in the longitudinal direction, and (b) is the surface (E) of the baseboard, which has a needle groove (F) extending in the longitudinal direction. (c) shows the case where wood glue (T) is applied to the back (C) of the baseboard (A), and (d) shows the case where the baseboard (A) is glued to the wall surface (B), with a tacker needle (H) driven into the needle groove (F).

[0006] 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 because they are water-resistant, there is no problem even if water droplets adhere to the surface.

[0007] As shown in Figure 7(d), the baseboard (A) is attached to the wall surface (B) by applying wood glue (T) to the backside, and Figure 8 shows the case where baseboards (A), (A)... are installed. In this way, the protruding corner of the mutually perpendicular baseboards (A), (A) is open, and the end faces (R), (R) are exposed. A corner cap is attached to close this opening (J). Figure 9 shows the case where a corner cap (L) is attached to the opening (J), and the protruding corner of the opening (J) is closed by the corner cap (L).

[0008] The corner caps (ru) are applied with wood glue (to) in the same way as the baseboards (i) and are glued to the end faces (ri) and (ri) of the baseboards (i), (i), but if the corner caps (ru) are made of resin, they will not adhere completely and will fall off. Incidentally, various patent applications have been filed in the past regarding corner caps that can be attached to the outside and inside corners of baseboards and methods for attaching them.

[0009] The "Corner material for wall construction materials, and mounting structure and construction method for wall construction materials using said corner material" in JP 2020-26719 makes it easier to finish wall construction materials such as baseboards and moldings at inside or outside corners. This corner piece for inside baseboards, used to hide gaps between baseboards at inside corners, consists of a surface material with a covering piece that expands like a wing depending on the angle of the inside corner and a fitting part that protrudes from the covering piece to the back side, and a base part with a contact piece that expands like a wing depending on the angle of the inside corner and a fitting part that protrudes from the contact piece to the front side. The contact piece is sandwiched between the wall surface and the end of the baseboard at the inside corner, and is held in place by fixing the baseboard to the wall surface, so there is no need to fix it to the wall with adhesive or nails, making installation easy.

[0010] The "baseboard connection part cover material" disclosed in JP 2007-285049 A is a baseboard connection part cover material that can easily connect baseboards at protruding corners of walls while improving the aesthetic appearance and can also accommodate shrinkage of the baseboards. The cover body has one receiving portion that fits over the end of one baseboard and another receiving portion that fits over the end of the other baseboard, and within this cover body are multiple reinforcing ribs that are spaced apart from one another so that the end face of each reinforcing rib abuts against the end face of one baseboard fitted into one receiving portion and the outer surface of the outermost reinforcing rib abuts against the end face of the other baseboard fitted into the other receiving portion, and adhesive reservoirs are provided using the empty space between the reinforcing ribs to store adhesive, and a recess for storing adhesive is provided on the outer surface of the outermost reinforcing rib. [Patent Document 1] "Corner material for wall construction, and mounting structure and construction method for wall construction using said corner material" pertaining to JP 2020-26719 A [Patent Document 2] "Baseboard connection part cover material" according to JP 2007-285049 A DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0011] In order to close the opening formed between the two baseboards that are installed perpendicular to each other, corner caps are attached. However, if the corner caps are made of resin, they may peel off depending on the adhesive bond used. The problem that the present invention aims to solve is this problem, and to provide a corner cap that will not peel off from the opening regardless of the material it is made of. [Means for solving the problem]

[0012] The corner caps of this invention consist of a cap body that fits into openings formed in the end faces of both baseboards, and legs that protrude vertically from the cap body. Here, the shape of the cap body is not particularly limited, and it is formed in a manner that fits into the opening and does not impair the external design of the corner portion of the baseboard. The cap body has two contact surfaces so that no gap is formed between the cap body and the end face of the baseboard, and the leg portion projects from one of the contact surfaces.

[0013] When the cap body is fitted into the opening, the leg is fitted into a glue reservoir groove provided on the back surface of the baseboard, and the glue stored in the glue reservoir groove hardens, fixing the leg so that it does not come out of the glue reservoir groove. For this purpose, the legs are formed with recesses and holes, and when the glue flows into the recesses and holes and hardens, the legs are fastened and the cap body is fixed to the opening. The corner caps may be made of resin, wood, or other materials. [Effects of the Invention]

[0014] The corner cap for baseboards according to the present invention comprises a cap body and legs, and the cap body can be fitted into openings formed at the corners of both baseboards. The legs are fitted into glue reservoir grooves formed on the backside of the baseboard, and when the baseboard is glued to the wall, part of the adhesive bond applied to the backside flows into the glue reservoir grooves and fills in the irregularities and holes in the legs. Therefore, once the adhesive bond hardens, the legs are fixed and do not come out of the adhesive reservoir grooves, and the corner caps are fixed so that they do not come off.

[0016] 1 shows an embodiment of a corner cap 1a according to the present invention, which is composed of a cap body 2 and a leg portion 3. The cap body 2 stands vertically and has two contact surfaces 4a, 4b on its rear side and two surfaces 5a, 5b on its front side, with a corner surface 6 between the two surfaces 5a, 5b. The leg portion 3 protrudes horizontally from one contact surface 4a of the cap body 2. The leg 3 is sized to fit into a glue reservoir groove formed on the back surface of the baseboard, and a hole 7 penetrates the leg 3. The size and shape of the hole 7 are not limited, and it can be, for example, a circular hole 7a, a triangular hole 7b, a square hole 7c, an elliptical hole 7d, or an oblong hole 7e.

[0017] 2 shows another embodiment of corner cap 1b according to the present invention, which, like corner cap 1a, is composed of cap body 2 and leg portion 3. Cap body 2 stands vertically and similarly has two contact surfaces 4a, 4b on the back side and two surfaces 5a, 5b on the front side, with corner surface 6 provided between surfaces 5a, 5b. The leg portion 3 protrudes horizontally from one contact surface 4a of cap body 2. The leg portion 3 is sized to fit into a glue reservoir groove formed on the back surface of the baseboard, and has multiple recesses 8, 8.... The size and shape of the recesses 8 are not limited, and can be, for example, a circular recess 8a, a triangular recess 8b, or a square recess 8c.

[0018] FIG. 3 shows another embodiment of a corner cap 1c according to the present invention, which is composed of a cap body 2 and a leg portion 3, similar to the corner caps 1a and 1b. The cap body 2 stands vertically and has two contact surfaces 4a, 4b on the back side and two surfaces 5a, 5b on the front side, with a corner surface 6 between the two surfaces 5a, 5b. The leg portion 3 protrudes horizontally from one contact surface 4a of the cap body 2. The leg 3 is sized to fit into the glue reservoir groove formed on the back surface of the baseboard, and has a U-shape 9 at the tip. There are no restrictions on the specific size and shape of the U-shape.

[0019] FIG. 4 shows a corner cap 1d according to yet another embodiment of the present invention. The corner cap 1d is composed of a cap body 2 and a leg portion 3, similar to the corner caps 1a and 1b. The cap body 2 stands vertically and has two contact surfaces 4a, 4b on the back side and two surfaces 5a, 5b on the front side, with a corner surface 6 between the two surfaces 5a, 5b. The leg portion 3 protrudes horizontally from one contact surface 4a of the cap body 2. The leg 3 is sized to fit into the glue reservoir groove formed on the back surface of the baseboard, and has an unevenness 10 at its tip. Unlike the case of Figure 2, the unevenness 10 is a groove extending in the vertical direction, and there are no restrictions on its specific size or shape.

[0020] FIG. 5 shows the corners of the baseboards 12a and 12b, which are attached to the wall surfaces 11a and 11b with adhesive, with the end faces 13a and 13b of the baseboards 12a and 12b exposed. The baseboards 12a and 12b are adhered to the wall surface by applying adhesive bond to the backside, but since it takes time for the adhesive bond to harden and for the baseboards 12a and 12b to be completely fixed, they are temporarily fixed by driving tacker needles into needle grooves 15 formed on the surface 14. The adhesive bond applied to the back surface flows into the adhesive reservoir groove 16 on the back surface when the baseboards 12a, 12b are pressed against a wall surface.

[0021] FIG. 6 shows the case where the corner cap 1 is attached, and the corner cap 1 can be fitted into the opening formed between the end faces 13a, 13b of both baseboards 12a, 12b shown in FIG. One contact surface 4a formed on the rear surface of the corner cap 1 contacts the end surface 13a, and the other contact surface 4b contacts the end surface 13b. The crossing angle between the contact surfaces 4a, 4b is the same as the crossing angle between the end surfaces 13a, 13b, and the corner cap 1 is attached without any gap between the end surfaces 13a, 13b.

[0022] The leg part 3 projecting from the cap body 2 of the corner cap 1 is fitted into the glue reservoir groove 16 of the baseboard 12a and intertwines with the adhesive bond flowing into the glue reservoir groove 16. If the adhesive bond 17 hardens over time, the fitted leg 3 is fixed by the adhesive bond 17 and will not come out of the glue reservoir groove 16, and the corner cap 1 will be fixed.

[0023] Incidentally, the intersection angle between the two contact surfaces 4a, 4b provided on the cap body 2 of the corner cap 1 is not limited to 90°, but is made the same as the intersection angle between the end surfaces 13a, 13b of the baseboards 12a, 12b adhered to the two wall surfaces 11a, 11b. Furthermore, there is no limitation on the material of the corner cap 1, and it may be made of resin or metal. [Explanation of symbols]
