DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings (FIGS. 1 to 6). [Embodiment 1] Figs. 1 to 4 First Embodiment A base board corner cover 1 and a base board structure 30 according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is an overall perspective view showing the front side of the overall configuration of a skirting board corner cover 1 and a skirting board structure 30 according to a first embodiment of the present invention, as viewed obliquely from above. FIG. 2 is a rear perspective view of the base board corner cover shown in FIG. 1, seen obliquely from above on the rear side in a state in which the base board corner cover is separated from the base board. FIG. 3 is a perspective view of the joint state of the pair of base boards shown in FIG. 1, seen obliquely from above. FIG. 4 is an end view showing the covering state of the pair of base boards shown in FIG. 1 with the base board corner cover as viewed from the arrow symbol FSA in FIG.

[0011] The baseboard corner cover 1 in this embodiment is located at the junction 26 between a wall surface 22 having a corner 20 and a floor surface 24, and covers the joint 14 where a pair of baseboards 10, each of which has a parallel surface 12 extending parallel to the wall surface 22 and an upper end surface 13 on the outside that extends from the upper end of the parallel surface 12 to the wall surface 22, join together at the corner 20. The baseboard corner cover 1 comprises a main body 3 which is a thin plate that conforms to the parallel surface 12 and contacts the parallel surface 12 to cover and hide the space between a pair of baseboards 10 at a joint 14, and an upper end 6 which is a thin plate that extends from the main body 3 and conforms to the upper end surface 13, covering the upper end surface 13 and hiding the space between the pair of baseboards 10 at the joint 14. The main body 3 has a recess 4 on the front side that is recessed in a direction facing the corner 20, and a protrusion 5 on the back side that protrudes in a direction facing the corner 20 as a back side integral with the recess 4, the recess 4 has a recessed surface 4f located parallel to each of the end faces 16 that the pair of baseboards 10 have, and the protrusion 5 has a protrusion surface 5f located parallel to each of the pair of end faces 16.

[0012] The skirting board corner cover 1 has a main body 3 and an upper end 6, and covers the corners 20 across both of a pair of skirting boards 10 joined at the corners 20 so as to hide the gap between the skirting boards 10. The skirting board corner cover 1 is made thin and lightweight from the perspective of the aesthetic appearance of the surfaces (parallel faces 12 and upper end faces 13) of the skirting boards 10. Furthermore, the recessed portion 4 on the front side and the protruding portion 5 on the back side are one face and the other, making it easy to ensure the mechanical strength of the skirting board corner cover 1. The baseboard corner cover 1 has a main body 3 which has a recess 4 on the front side recessed in a direction facing the corner 20, and a protrusion 5 on the back side protruding in a direction facing the corner 20 corresponding to the recess 4, the recess 4 having a recessed surface 4f positioned parallel to the end face 16 of the baseboard 10, and the protrusion 5 having a protrusion surface 5f positioned parallel to the end face 16 of the baseboard 10. Since each concave surface 4f is positioned so as to intersect with the adjacent main body portion 3, and each convex surface 5f is positioned in a direction intersecting with the adjacent main body portion 3, it is easy to improve the strength of the baseboard corner cover 1 and the reliability. The concave surface 4f preferably intersects with the main body portion 3 in a perpendicular direction. The convex surface 5f preferably intersects with the main body portion 3 in a perpendicular direction. Intersecting at a right angle makes it easy to reliably ensure strength.

[0013] The convex surface 5f is spaced apart from the pair of end surfaces 16 (FIG. 4). Since the convex surface 5f is separated from the end surface 16, it is possible to avoid contact with the end surface 16, suppress the mechanical pressure from the end surface 16, and easily maintain the shape, and it is easy to further reinforce the effectiveness (mechanical strength) of the baseboard corner cover 1. The baseboard corner cover 1 is thin and lightweight, while easily maintaining and improving its mechanical strength.

[0014] The main body 3 includes a pair of adhesive portions 9 that are adhered to the parallel surfaces 12 at a pair of adhesive positions 9p adjacent to the pair of convex surfaces 5f. The baseboard corner cover 1 has a pair of adhesive portions 9 that are adhered to the parallel surfaces 12 at a pair of adhesive positions 9p adjacent to the convex surface 5f on the back side, so that it can be reliably fixed in contact with the pair of parallel surfaces 12, making it easy to ensure the reliability of the cover. The adhesive portion 9 may be formed by previously placing a double-sided tape as an adhesive member, or may be formed by applying an adhesive at the work site. A pair of baseboards 10 each have a decorative groove 11 that separates and decorates a lower portion on the floor side from an upper portion on the upper end face 13 side, and a main body portion 3 has a main body groove 7 that runs along the decorative groove 11. The skirting board corner cover 1 has a main groove 7 that fits along the decorative groove 11 of the skirting board 10, so that it can be easily positioned so as to cover the skirting board 10 with precision.

[0015] The depth dimension D4 of the recess 4 is preferably approximately half the end face width W16 of the end face 16. If the base board 10 becomes misaligned at the joint 14 of the base board 10, the base board corner cover 1 can easily maintain a state away from the end face 16, and can easily suppress the occurrence of mechanical shock from the base board 10. The state of misalignment will be described separately in the second embodiment (FIGS. 5 and 6). By limiting the positional deviation of the base board 10 with respect to the adjacent base board 10 to approximately half the end face width W16, it becomes easier to clarify the allowable range and to easily improve workability. The depth dimension D4 of the recess 4 is the dimension in the depth direction of the recess 4 from the surface of the main body 3. In other words, it is the distance from the surface of the main body 3 to the intersection position of the paired recess surfaces 4f. The end face width W16 is the horizontal width dimension of the end face 16 exposed at the joint 14.

[0016] The baseboard structure 30 of this embodiment is a baseboard structure 30 comprising a pair of baseboards 10 located at a junction 26 between a wall surface 22 having a corner 20 and a floor surface 24, and having on the outside a parallel surface 12 extending parallel to the wall surface 22 and an upper end surface 13 extending from the upper end of the parallel surface 12 to the wall surface 22, and a baseboard corner cover 1 covering a joint 14 where the baseboards 10 join to each other at the corner 20, wherein the baseboard corner cover 1 is a baseboard corner cover 1 relating to any one of the present embodiments. Since the base board corner cover 1 according to this embodiment is applied to the base board structure 30, it is easy to realize a base board structure 30 that effectively utilizes the characteristics of the base board corner cover 1 as they are.

[0017] [Embodiment 2] Figs. 5 and 6 The effect of the baseboard corner cover 1 according to the second embodiment of the present invention will be described with reference to Figures 5 and 6. Although this is called the second embodiment, the overall configuration is the same as that of the first embodiment, and this embodiment merely illustrates a case where the baseboard 10 is misaligned. Therefore, the same reference numerals as those in the first embodiment are used, and duplicated explanations of the same parts are omitted. FIG. 5 illustrates the misalignment of the base boards 10 at the joint 14 of a pair of base boards shown in FIG. 3 as an example of embodiment 2, and is an oblique view of the joint state of the base boards 10 as viewed diagonally from above. FIG. 6 is a misaligned covering end view showing the covering state of the base board corner cover 1 for the base board 10 shown in FIG. 5 as an end face state at the arrow symbol FSA shown in FIG.

[0018] The depth dimension D4 of the recess 4 is approximately half the end face width W16 of the end face 16. For this reason, if the baseboard 10 is displaced at the joint 14 of the baseboard 10, for example, when one of the baseboards 10 (the baseboard 10 on the left side in Figs. 5 and 6) is displaced by approximately half the end face width W16, the baseboard corner cover 1 arranged at the joint 14 can be easily kept apart from the end face 16 of the baseboard 10 in the normal position (the baseboard 10 on the right side in the same figures) as well as from the end face 16 on the displaced side (the baseboard 10 on the left side), making it easy to avoid and suppress the occurrence of mechanical shock from the baseboard 10. In other words, the positional misalignment of one base board 10 with respect to the other adjacent base board 10 can be limited to approximately half the end face width W16, making it easier to clarify the allowable range and improve workability. The depth dimension D4 of the recess 4 is the dimension in the depth direction of the recess 4 from the surface of the main body 3. In other words, it is the distance from the surface of the main body 3 to the intersection position of the paired recess surfaces 4f. The end face width W16 is the width dimension in the horizontal direction of the end face 16 exposed at the joint 14.

[0019] [Embodiment 3] Figs. 1 to 6 As the third embodiment of the present invention, additional explanation will be given on the baseboard corner cover 1. Although the baseboard corner cover 1 according to this embodiment is the third embodiment, it is substantially the same as the first and second embodiments, and merely provides additional explanation on the material that constitutes the baseboard corner cover 1. Therefore, the same reference numerals as the first and second embodiments are used, and duplicate explanations of the same parts are omitted as appropriate. The baseboard corner cover 1 according to this embodiment is easily formed from synthetic resin or molded paper. In particular, molded paper makes it easier to further improve the lightness and thickness. In other words, the main body 3 and upper end 6 of the baseboard corner cover 1 according to this embodiment are one piece of molded paper. Because the baseboard corner cover 1, which has the main body 3 and upper end 6, is one piece of molded paper, it is easy to achieve both a thin and lightweight design. In addition, it is easy to improve the environmental friendliness of the baseboard corner cover 1.

[0020] The baseboard corner cover 1 in this embodiment is located at the junction 26 between a wall surface 22 having a corner 20 and a floor surface 24, and covers the joint 14 where a pair of baseboards 10, each of which has a parallel surface 12 extending parallel to the wall surface 22 and an upper end surface 13 extending from the upper end of the parallel surface 12 to the wall surface 22 on the outside, join together at the corner 20. 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 12 and is bonded to the parallel surfaces 12 to cover and hide a pair of baseboards 10 at a joint 14, and an upper end 6 which is in the form of a thin plate that extends from the main body 3 and conforms to the upper end surface 13, covering the upper end surface 13 and hiding the pair of baseboards 10 at the joint 14. The baseboard corner cover 1 has a main body 3 and an upper end 6 which are formed as a single piece of molded paper.

[0021] In the baseboard corner cover 1, the main body 3 and upper end 6, which enclose the joint 14 of the baseboard 10, are made of a single, thin, molded paper that covers the joint 14 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, since the main body 3 and the upper end 6 are an integral piece of molded paper, they can be easily attached to the baseboard 10. Furthermore, since the main body 3 and the upper end 6 are an integral piece of thin plate-like material, they are less likely to deform and can be easily positioned along the parallel faces 12 and the upper end face 13 of the baseboard 10 with good facing properties. Furthermore, the protruding corner of the joint 14 (corner 20) has a recess 4 on the front side and a protrusion 5 on the back side, and since the recess 4 and protrusion 5 are molded in the same manner as the main body 3 and the upper end 6 at the same time, they are easily realized in the same way as the main body 3 and the upper end 6. In other words, the recess 4 and protrusion 5 are formed as a part of the main body 3 that faces the corner 20. The main body 3 (baseboard corner cover 1) is adhered to the parallel surface 12 (baseboard 10) by, for example, an adhesive portion 9 (FIG. 2) at an adhesive position 9p.

[0022] In the baseboard corner cover 1, the thickness of the main body 3 and the upper end 6 is preferably about 0.3 mm to about 0.6 mm. Since the main body 3 and the upper end 6 have a thickness of about 0.3 mm to about 0.6 mm, it is easier to more reliably 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 14 and the baseboard 10 is suppressed, making it easier to ensure strength and improve the aesthetic appearance. The thickness between the surface (front surface) of the recess 4 and the surface (rear surface) of the protrusion 5 is the same as the thickness of the main body 3 and the upper end 6 since they are molded to be the same as the thickness of the main body 3 and the upper end 6. When the main body 3 and the upper end 6 are made of molded paper, the surfaces of the main body 3 and the upper end 6 are preferably decorated with a surface decoration layer (not shown). The thickness of the surface decoration layer is about 40 μm to about 60 μm when the thickness of the main body 3 and the upper end 6 is about 0.3 mm to about 0.6 mm. The surface decorative layer is composed of multiple layers including, for example, an acrylic urethane layer, and can be easily matched to the pattern of the baseboard 10. The surface decorative layer is limited to about 10% of the thickness of the main body 3 and the upper end portion 6, so it has almost no effect on the dimensions. The surface decoration layer covers the surfaces of the main body 3 and the upper end 6, and therefore it is easy to improve the reliability of the main body 3 and the upper end 6, which are formed from molding paper.

[0023] In this embodiment, a manufacturing method of the baseboard corner cover 1 will be described. The manufacturing method of the baseboard corner cover 1 in this embodiment is a manufacturing method of the baseboard corner cover 1 which is located at the joint 26 between a wall surface 22 having a corner 20 and a floor surface 24, and covers the joint 14 where a pair of baseboards 10 which have on the outside a parallel surface 12 extending parallel to the wall surface 22 and an upper end surface 13 extending from the upper end of the parallel surface 12 to the wall surface 22 join together at the corner 20. The manufacturing method of the baseboard corner cover 1 includes a step of press-molding a paper raw material using a die having an integral shape corresponding to the main body 3 and the upper end 6, and a step of forming a surface decorative layer on the integrally molded main body 3 and upper end 6. The die has a shape corresponding to the recessed portion 4 and the protruding portion 5 which are processed simultaneously with the main body 3 and the upper end 6.

[0024] The manufacturing method of the baseboard corner cover 1 is a manufacturing method of the baseboard corner cover 1 relating to embodiment 1, and the main body portion 3, upper end portion 6, recessed portion 4, and protruding portion 5 that constitute the baseboard corner cover 1 are a single piece of molded paper formed by press molding paper raw material. Since the main body 3, upper end 6, recesses 4, and protrusions 5 are, for example, a press-molded integral piece of molded paper, the main body 3, upper end 6, recesses 4, and protrusions 5 can easily ensure the strength of a thin plate, the strength in bending between the main body 3 and upper end 6, and the strength between the recesses 4 and protrusions 5 as a single unit. Moreover, 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 and the embodiment 2. The color tone and physical properties of the paper raw material are appropriately adjusted in advance. [Industrial Applicability]

[0025] The present invention provides a new type of baseboard corner cover and a baseboard structure to which the same is applied, and thus can be effectively used in industry. [Explanation of symbols]
