FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings (FIGS. 1A to 5). [Embodiment 1] (Figs. 1A to 2C) The first embodiment relates to a baseboard corner cover 1 (outside corner structure), a baseboard structure 40 (outside corner structure) (Figures 1A to 1C), a baseboard corner cover 1 (inside corner structure), and a baseboard structure 40 (inside corner structure) (Figures 2A to 2C). A skirting board corner cover 1 having a protruding corner structure and a skirting board structure 40 will be described with reference to Figs. 1A to 1C. Figure 1A shows a baseboard corner cover 1 according to embodiment 1 of the present invention and a baseboard structure 40 to which the baseboard corner cover 1 is applied, and is an external oblique view showing the appearance of the baseboard corner cover 1 attached to the joint 13 of a baseboard 10 when applied to a corner 16 (projecting corner) as viewed diagonally from above and from the front. FIG. 1B is an external perspective view showing the base board corner cover 1 shown in FIG. 1A separated from the base board 10, and showing the front side as viewed from diagonally above as seen from the outside. FIG. 1C is an external perspective view showing the rear side of the baseboard corner cover 1 shown in FIG. 1B as viewed from the baseboard side, as viewed obliquely from above.

[0014] The baseboard corner cover 1 in this embodiment is located at the junction 17 between a wall surface 14 having a corner 16 and a floor surface 15, and covers the joint 13 where a pair of baseboards 10, each of which has a parallel surface 11 extending parallel to the wall surface 14 and an upper end surface 12 extending from the upper end of the parallel surface 11 to the wall surface 14 on the outside, join together at the corner 16. The baseboard corner cover 1 comprises a main body 3 which is in the form of a thin plate that conforms to the parallel surfaces 11 and is adhered to the parallel surfaces 11 to cover and hide a pair of baseboards 10 at a joint 13, and an upper end 4 which extends from the main body 3 and is in the form of a thin plate that conforms to the upper end surface 12, covering the upper end surface 12 and hiding the pair of baseboards 10 at the joint 13. The baseboard corner cover 1 has a main body 3 and an upper end 4 which are formed as a single piece of molded paper.

[0015] In the baseboard corner cover 1, the main body 3 and upper end 4, which enclose the joint 13 of the baseboard 10, are made of a single, thin, molded paper that covers the joint 13 of the baseboard 10, making it easy to achieve a lightweight and strong baseboard corner cover 1. This makes it easy to suppress the impact of the baseboard corner cover 1 on the baseboard 10. In addition, because the main body 3 and the upper end 4 are an integral piece of molded paper, they can be easily attached to the baseboard 10. In addition, because the main body 3 and the upper end 4 are an integral thin plate, they are less likely to deform and can be easily positioned along the parallel faces 11 and the upper end face 12 of the baseboard 10 with good facing properties. In addition, the same effects can be easily achieved regardless of whether the joint 13 (corner 16) is a protruding corner or a recessed corner. The body portion 3 (baseboard corner cover 1) is attached to the parallel surface 11 (baseboard 10) by, for example, double-sided tape 20 (FIG. 1C) or by applying an adhesive.

[0016] In the baseboard corner cover 1 (FIG. 1C), the thickness T3 of the main body 3 and the thickness T4 of the upper end 4 are preferably from about 0.3 mm to about 0.6 mm. The thicknesses (thickness T3, thickness T4) of the main body 3 and upper end 4 of the baseboard corner cover 1 are approximately 0.3 mm to approximately 0.6 mm, which more reliably makes it easier to achieve a lightweight and strong baseboard corner cover 1. In addition, since the thickness is limited, the step between the outer side of the joint 13 and the baseboard 10 is suppressed, making it easier to ensure strength and improve the aesthetic appearance. The thickness T3 and the thickness T4 are more preferably about 0.4 mm to 0.5 mm.

[0017] In the baseboard corner cover 1, the main body 3 has a molded uneven portion 8 that fits along the uneven portion 18 (e.g., a groove shape) of the parallel surface 11 (baseboard 10). The molded uneven portion 8 increases the precision of the main body 3 that fits along the parallel surface 11, and also makes it easy to increase the strength of the main body 3. Since the molded uneven portion 8 is molded simultaneously with molding the main body portion 3 and the upper end portion 4, the precision and strength of the main body portion 3 can be easily ensured. The uneven portion 18 is, for example, in the form of a groove formed in advance on the parallel surface 11 of the baseboard 10 .

[0018] The baseboard structure 40 of this embodiment is located at a junction 17 between a wall surface 14 and a floor surface 15 having a corner 16, and comprises a pair of baseboards 10 that are joined to each other at the corner 16 via a joint 13, and a baseboard corner cover 1 that covers the joint 13 between the pair of baseboards 10 at the corner 16. In the baseboard structure 40, a pair of baseboards 10 have parallel surfaces 11 extending parallel to the wall surface 14 and upper end surfaces 12 extending from the upper ends of the parallel surfaces 11 to the wall surface 14 on the outside, and the baseboard corner cover 1 is a baseboard corner cover 1 relating to this embodiment. The skirting board structure 40 can effectively realize the characteristics of the skirting board corner cover 1 at the joint 13 of the skirting board 10. The back side of the main body 3 (i.e., the skirting board corner cover 1) is adhered to the parallel surface 11 via a double-sided tape 20, for example.

[0019] The base board corner cover 1 and the base board structure 40 having an inside corner structure will be described with reference to Figs. 2A to 2C. The base board corner cover 1 and base board structure 40 shown in Figures 2A to 2C are different only in that they are inside corner structures, whereas the base board corner cover 1 and base board structure 40 shown in Figures 1A to 1C are outside corner structures. Accordingly, the shape of the base board corner cover 1 corresponds to the outside corner structure in Figure 1A, and corresponds to the inside corner structure in Figure 2A. The only difference between the baseboard corner cover 1 in Figure 1A and the baseboard corner cover 1 in Figure 2A is the shape due to the difference between the convex corner 16 and the concave corner 16. In the case of the outside corner structure and the inside corner structure, the actual difference is simply whether the corner 16 (joint 13) is convex or concave, and there are no actual differences in other parts. Since there is no actual difference between the baseboard corner cover 1 in Figure 1A and the baseboard corner cover 1 in Figure 2A, the same parts in Figure 2A as those in Figure 1A are given the same symbols, and the explanation of both will be omitted as appropriate as this embodiment.

[0020] Figure 2A shows a baseboard corner cover 1 according to embodiment 1 of the present invention and a baseboard structure 40 to which the baseboard corner cover 1 is applied, and is an external oblique view from diagonally above the front showing the state in which the baseboard corner cover 1 is attached to the joint 13 of the baseboard 10 when applied to a corner 16 (recessed corner). FIG. 2B is an external perspective view showing the base board corner cover 1 shown in FIG. 2A separated from the base board 10, showing the front side as viewed from the outside, obliquely from above. FIG. 2C is an external perspective view showing the rear side of the baseboard corner cover 1 shown in FIG. 2B as viewed from the baseboard side, as viewed obliquely from above.

[0021] The baseboard corner cover 1 in this embodiment is located at the junction 17 between a wall surface 14 having a corner 16 and a floor surface 15, and covers the joint 13 where a pair of baseboards 10, each of which has a parallel surface 11 extending parallel to the wall surface 14 and an upper end surface 12 extending from the upper end of the parallel surface 11 to the wall surface 14 on the outside, join together at the corner 16. The baseboard corner cover 1 comprises a main body 3 which is in the form of a thin plate that conforms to the parallel surfaces 11 and is adhered to the parallel surfaces 11 to cover and hide a pair of baseboards 10 at a joint 13, and an upper end 4 which extends from the main body 3 and is in the form of a thin plate that conforms to the upper end surface 12, covering the upper end surface 12 and hiding the pair of baseboards 10 at the joint 13. The baseboard corner cover 1 has a main body 3 and an upper end 4 which are formed as a single piece of molded paper.

[0022] In the baseboard corner cover 1, the main body 3 and upper end 4, which enclose the joint 13 of the baseboard 10, are made of a single, thin, molded paper that covers the joint 13 of the baseboard 10, making it easy to achieve a lightweight and strong baseboard corner cover 1. This makes it easy to suppress the impact of the baseboard corner cover 1 on the baseboard 10. In addition, because the main body 3 and the upper end 4 are an integral piece of molded paper, they can be easily attached to the baseboard 10. In addition, because the main body 3 and the upper end 4 are an integral thin plate, they are less likely to deform and can be easily positioned along the parallel faces 11 and the upper end face 12 of the baseboard 10 with good facing properties. In addition, the same effects can be easily achieved regardless of whether the joint 13 (corner 16) is a protruding corner or a recessed corner. The body portion 3 (baseboard corner cover 1) is attached to the parallel surface 11 (baseboard 10) by, for example, double-sided tape 20 (FIG. 2C) or by applying an adhesive.

[0023] In the baseboard corner cover 1 (FIG. 2B), the thickness T3 of the main body 3 and the thickness T4 of the upper end 4 are preferably from about 0.3 mm to about 0.6 mm. The thicknesses (thickness T3, thickness T4) of the main body 3 and upper end 4 of the baseboard corner cover 1 are approximately 0.3 mm to approximately 0.6 mm, which more reliably makes it easier to achieve a lightweight and strong baseboard corner cover 1. In addition, since the thickness is limited, the step between the outer side of the joint 13 and the baseboard 10 is suppressed, making it easier to ensure strength and improve the aesthetic appearance. The thickness T3 and the thickness T4 are more preferably about 0.4 mm to 0.5 mm.

[0024] In the baseboard corner cover 1, the main body 3 has a molded uneven portion 8 that fits along the uneven portion 18 (e.g., a groove shape) of the parallel surface 11 (baseboard 10). The molded uneven portion 8 increases the precision of the main body 3 that fits along the parallel surface 11, and also makes it easy to increase the strength of the main body 3. Since the molded uneven portion 8 is molded simultaneously with molding the main body portion 3 and the upper end portion 4, the precision and strength of the main body portion 3 can be easily ensured. The uneven portion 18 is, for example, in the form of a groove formed in advance on the parallel surface 11 of the baseboard 10 .

[0025] The baseboard structure 40 of this embodiment is located at a junction 17 between a wall surface 14 and a floor surface 15 having a corner 16, and comprises a pair of baseboards 10 that are joined to each other at the corner 16 via a joint 13, and a baseboard corner cover 1 that covers the joint 13 between the pair of baseboards 10 at the corner 16. In the baseboard structure 40, a pair of baseboards 10 have parallel surfaces 11 extending parallel to the wall surface 14 and upper end surfaces 12 extending from the upper ends of the parallel surfaces 11 to the wall surface 14 on the outside, and the baseboard corner cover 1 is a baseboard corner cover 1 relating to this embodiment. The skirting board structure 40 can effectively realize the characteristics of the skirting board corner cover 1 at the joint 13 of the skirting board 10. The back side of the main body 3 (i.e., the skirting board corner cover 1) is adhered to the parallel surface 11 via a double-sided tape 20, for example.

[0026] [Embodiment 2] (Figs. 3 and 4) The second embodiment relates to a molding corner cover 2 and a molding structure 42 (FIG. 3: outside corner structure; FIG. 4: inside corner structure). As in the case of the first embodiment, there is a difference between the protruding corner structure and the recessed corner structure between Fig. 3 and Fig. 4. Accordingly, the shape of the molding corner cover 2 corresponds to the protruding corner structure in Fig. 3 and corresponds to the recessed corner structure in Fig. 4. The only difference between the molding corner cover 2 in Fig. 3 and the molding corner cover 2 in Fig. 4 is the shape due to the difference between the convex corner 16 and the concave corner 16, and the same is true for the molding structure 42 in Fig. 3 and the molding structure 42 in Fig. 4. Therefore, the explanation of Fig. 3 will be mainly given, and in Fig. 4, the same reference numerals as in Fig. 3 will be used and the explanation of Fig. 4 will be omitted as appropriate. Figure 3 shows a molding corner cover 2 relating to embodiment 2 of the present invention and a molding structure 42 to which the molding corner cover 2 is applied, and is an external oblique view showing the appearance of the molding corner cover 2 attached to the joint 13 of the molding 10d10d when applied to a corner 16 (outer corner) as viewed diagonally from below and from the front. Figure 4 shows a molding corner cover 2 relating to embodiment 2 of the present invention and a molding structure 42 to which the molding corner cover 2 is applied, and is an external oblique view showing the appearance of the molding corner cover 2 attached to the joint 13 of the molding 10d10d when applied to a corner 16 (inside corner) as viewed diagonally from below and from the front.

[0027] The molding corner cover 2 of this embodiment relates to a molding corner cover 2 and a molding structure 42 whose vertical arrangement structure is opposite to that of the base board corner cover 1 and base board structure 40 of the first embodiment. The molding corner cover 2 and molding structure 42 are different from the baseboard corner cover 1 and baseboard structure 40 in the first embodiment in that they are structured upside down in the vertical direction. In other words, the molding corner cover 2 is basically different in that it is arranged on the ceiling surface 15d side, and there are no other differences in the configuration, so the symbols in the first embodiment will be used as appropriate and the explanation may be omitted.

[0028] The molding corner cover 2 in this embodiment is located at the joint 17 between a wall surface 14 having a corner 16 and a ceiling surface 15d, and covers the joint 13 where a pair of moldings 10d, which have on the outside a parallel surface 11 extending parallel to the wall surface 14 and a lower end surface 12d extending from the lower end of the parallel surface 11 to the wall surface 14, join together at the corner 16. The molding corner cover 2 comprises a main body 3 having a thin plate shape that conforms to the parallel surface 11 and is bonded to the parallel surface 11 to cover and hide a pair of molding edges 10d at a joint 13, and a lower end portion 4d that extends from the main body 3 and has a thin plate shape that conforms to the lower end surface 12d, covering the lower end surface 12d and hiding the pair of molding edges 10d at the joint 13. The main body 3 and the lower end 4d of the molding corner cover 2 are made of a single molded piece of paper. Note that the lower end 4d is shown as being different from the upper end 4 in order to show the difference from the skirting board corner cover 1, but the actual situation is essentially the same, with only the positioning being different.

[0029] In the molding corner cover 2, the main body 3 and the lower end 4d, which contain the joint 13 of the molding 10d, are made of a thin, integral molded paper that covers the joint 13 of the molding 10d, making it easy to achieve a lightweight and strong molding corner cover 2. This makes it easy to suppress the influence on the molding 10d as the molding corner cover 2. In the molding corner cover 2 located on the ceiling surface 15d side, the effect of weight reduction is even greater than in the case of the baseboard corner cover 1, since the influence of a fall is suppressed. In addition, since the main body 3 and the lower end 4d are made of an integral molded paper, they can be easily attached to the molding 10d. Also, since the main body 3 and the lower end 4d are made of an integral thin plate, they are less likely to deform and can be easily positioned along the parallel surface 11 and the lower end surface 12d of the molding 10d with good facing properties. In addition, the same effect can be easily achieved regardless of whether the joint 13 (corner 16) is an external corner or an internal corner. The lower end 4d may have the same configuration as the upper end 4 (Embodiment 1). The adhesion to the parallel surface 11 of the molding corner cover 2 is the same as in Embodiment 1. In addition, the weight reduction effect is even greater in the molding 10d.

[0030] In the molding corner cover 2 (FIG. 3), the thickness of the main body 3 and the lower end 4d is preferably about 0.3 mm to about 0.6 mm, similar to embodiment 1. Specifically, the thickness of the main body 3 is the thickness T3 shown in FIG. 1C, and the thickness of the lower end 4d is the same as the thickness T4 of the upper end 4 shown in FIG. 1C. That is, the lower end 4d has the same aspect as the upper end 4. This makes it easier to more reliably achieve weight reduction and strength assurance for the molding corner cover 2. Also, since the thickness is limited, it is easier to ensure strength by suppressing the step between the joint portion 13 and the outer molding 10d, and it is easier to improve the aesthetics. The thickness T3 and the thickness of the lower end 4d are more preferably about 0.4 mm to 0.5 mm.

[0031] In the molding corner cover 2, the main body 3 has a molded uneven portion 8d that fits along the uneven portion 18d of the parallel surface 11. The molded uneven portion 8d increases the precision of the main body 3 in the shape that fits along the parallel surface 11 (molding 10d), and also makes it easy to increase the strength of the main body 3. The molded uneven portion 8d is molded simultaneously with molding of the main body 3 and the lower end portion 4d, and therefore it is easy to ensure the precision and strength of the main body 3. The uneven portion 18d is, for example, a groove shape formed in advance on the parallel surface 11 of the molding edge 10d.

[0032] The molding structure 42 of this embodiment is located at a joint 17 between a wall surface 14 having a corner 16 and a ceiling surface 15d, and comprises a pair of moldings 10d joined to each other via a joint 13 at the corner 16, and a molding corner cover 2 covering the joint 13 between the pair of moldings 10d at the corner 16. In the molding structure 42, a pair of moldings 10d have on the outside parallel surfaces 11 extending parallel to the wall surface 14 and lower end surfaces 12d extending from the lower ends of the parallel surfaces 11 to the wall surface 14, and the molding corner cover 2 is a molding corner cover 2 relating to this embodiment. The molding structure 42 can effectively realize the characteristics of the molding corner cover 2 at the joint 13 of the molding 10d. The main body 3 (back side) is adhered to the parallel surface 11 via a double-sided tape 20, for example.

[0033] [Embodiment 3] (Figure 5) The third embodiment relates to a surface decorative layer 6 provided on the surface of the baseboard corner cover 1 according to the first embodiment and the molding corner cover 2 according to the second embodiment. In the baseboard corner cover 1, the main body 3 and the upper end 4 are provided with a surface decoration layer 6 containing a synthetic resin on at least the exposed surfaces. The main body 3 and the upper end 4 of the baseboard corner cover 1 are provided with a surface decoration layer 6 containing synthetic resin at least on the exposed surface (the surface to be aesthetically pleasing), which makes it easy to improve reliability in the usage environment in addition to aesthetics, and to maintain light weight and strength for a long time. The form of decoration is realized by, for example, wood grain. The surface decorative layer 6 is a multi-layer including an acrylic urethane layer 6s, and has a thickness of approximately 40 μm to approximately 60 μm. The thickness T6 of the surface decorative layer 6 is approximately 50 μm (approximately 40 μm to approximately 60 μm), which can be suppressed to approximately 10% of the thickness of the main body 3 and the upper end portion 4, making it easy to suppress the effect on the thickness dimension of the baseboard corner cover 1. In addition, since it is composed of multiple layers including the acrylic urethane layer 6s, it is easy to realize the pattern of the surface decoration. The surface decoration layer 6 is laminated in the order of the base layer 6p, the acrylic urethane layer 6s, the pattern forming layer 6i, and the surface protection layer 6h on the main body 3 and the upper end 4. Since the base board corner cover 1 is laminated in the order of the base layer 6p, the acrylic urethane layer 6s, the pattern forming layer 6i, and the surface protection layer 6h, it is easy to realize a stable surface decoration layer 6 with high reliability. The pattern forming layer 6i realizes, for example, wood grain, and the surface protection layer 6h is likely to improve stability against the usage environment. The base layer 6p is, for example, a PP primer. The pattern forming layer 6i is, for example, a nitrocellulose ink and a medium for color matching. The surface protection layer 6h is likely to be, for example, an acrylic urethane. The surface decoration layer 6 is laminated using a spray gun or the like. The aspect of the surface decorative layer 6 is the same in the molding corner cover 2 (main body portion 3, lower end portion 4d), so a description of the surface decorative layer 6 in the molding corner cover 2 will be omitted.

[0034] [Embodiment 4] (Method of manufacturing skirting board corner cover and molding corner cover) The fourth embodiment relates to a manufacturing method of the baseboard corner cover 1 (first embodiment) and the molding corner cover 2 (second embodiment).

In addition, according to the manufacturing method of the base board corner cover 1 according to the present embodiment, it is easy to easily and efficiently manufacture the base board corner cover 1 according to the embodiment 1. The color tone and physical properties of the paper raw material are appropriately adjusted in advance.

[0035] The manufacturing method of the molding corner cover 2 in this embodiment is a manufacturing method of the molding corner cover 2 which covers the joint portion 13 where a pair of moldings 10d are joined to each other at the corner 16 and are located at the joint portion 17 between a wall surface 14 having a corner 16 and a ceiling surface 15d, and have on the outside a parallel surface 11 extending parallel to the wall surface 14 and a lower end surface 12d extending from the lower end of the parallel surface 11 to the wall surface 14. The manufacturing method of the molding corner cover 2 includes a step of press-molding a paper raw material using a mold having an integral shape corresponding to the main body 3 and the lower end 4d, and a step of forming a surface decorative layer 6 on the integrally molded main body 3 and lower end 4d. The manufacturing method of the molding corner cover 2 is a manufacturing method of the molding corner cover 2 relating to embodiment 2, and the main body 3 and lower end 4d that constitute the molding corner cover 2 are an integral molded paper formed by press molding paper raw material. Since the main body 3 and the lower end 4d are press-molded molded paper, it is easy to ensure the thin plate strength of the main body 3 and the lower end 4d, as well as the strength against bending between the main body 3 and the lower end 4d. Moreover, according to the manufacturing method of the molding corner cover 2 according to the present embodiment, the molding corner cover 2 according to the second embodiment can be easily and efficiently manufactured.
