Description

[Technical Field]

[0001] The present invention relates to a structure for attaching decorative panels to the wall surfaces of buildings, and more particularly to a base material and an attachment structure used for decorating interior and exterior surfaces, for example. [Background technology]

[0002] Conventionally, decorative panels (e.g., tiles, panels, etc.) used for interior and exterior applications have been attached using one base material per decorative panel, or using a long, rail-shaped base to attach multiple decorative panels. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 8-151764 [Patent Document 2] Japanese Patent Application Laid-Open No. 2001-090314 Summary of the Invention [Problem to be solved by the invention]

[0004] Decorative panels are mainly used for interior decoration or on the facades of buildings, and are not often required to function as walls themselves. Furthermore, high wind pressure resistance, such as that required for exterior walls, is often not required, and so there has been a demand for a simple method of attaching decorative panels that allows anyone to install them and offers a high degree of freedom in design.

[0005] Patent Document 1 proposes a method of attaching one base material per tile, and describes an installation method in which the tile is fitted into the base material. However, because the base material and the tile differ in size, a method in which the base material is first attached to the existing wall and then the tile is attached requires marking out the tile size and then attaching the base material. Patent Document 2 also proposes a method in which multiple tiles or decorative materials are attached to a single base material. However, because the base material is rail-shaped, the decorative plates can only be arranged in a straight line vertically or horizontally or in a rectangular shape. It is difficult to arrange a single piece or a circle, which may limit design freedom. [Means for solving the problem]

[0006] Therefore, the present invention provides a decorative plate base material that is approximately square when viewed from the front and has an approximately U-shaped cross section, and a simple decorative plate mounting structure that uses the decorative plate base material.

[0007] Specifically, the decorative plate base material of the present invention provides a decorative plate base material having an approximately U-shaped cross section in a first direction, characterized by having a fixing surface that is approximately square when viewed from the front, a surrounding portion arranged along the outer edge of the fixing surface, a support portion arranged on the extension of two of the surrounding portions located diagonally opposite each other, and multiple convex portions provided on the support portion, with an inclined portion at the tip of the support portion that slopes toward the fixing surface, and a decorative plate mounting structure using this base material.

[0008] Furthermore, the support portion of the decorative plate base material of the present invention is characterized in that a first convex portion is provided on the fixing surface side and a second convex portion is provided on the inclined portion side so as to be approximately parallel to the fixing surface, and the first convex portion and the second convex portion are provided in positions where they overlap on the wall surface and in a second direction perpendicular to the first direction. [Effects of the Invention]

[0009] The decorative plate base material and decorative plate mounting structure of the present invention eliminate the need for complicated mounting procedures and allow anyone to easily mount a decorative plate.

[0010] More specifically, the present invention provides a decorative plate base material used to attach a decorative plate that is approximately square in front view and has legs on at least two sides, which reduces the number of parts required to attach the decorative plate and allows the decorative plate to be attached in a simple manner that improves on the complicated installation process that has been used up to now.

[0013] The axes shown in each figure indicate the direction of that figure, and the axes shown in other figures also indicate the same directions. The first direction is vertical to the ground, and the second and third directions are horizontal to the ground. The second direction is perpendicular to the wall surface and perpendicular to the first direction, and the third direction is parallel to the wall surface and perpendicular to the first direction.

[0014] FIG. 1 shows a decorative plate base material 1 according to the present invention, which includes a fixing surface 2 that is roughly square when viewed from the front, and surrounding portions 4 that extend roughly vertically from each of the four outer edges of the fixing surface 2. Two of the four surrounding portions 4 are provided with mounting portions 5. Each mounting portion 5 is composed of a step 6 that slopes toward the opposite side, a support portion 7 that extends from the end of the step 6 roughly parallel to the surrounding portion 4, an inclined portion 8 that slopes the tip of the support portion 7 roughly parallel to the step 6 toward the opposite side, and a plurality of protrusions 9 on the support portion 7. Furthermore, a notch 11 is provided between adjacent surrounding portions 4.

[0015] The fixing portion 2 is provided with fixing holes 3, and multiple fixing holes 3 with different diameters, such as fixing hole 3a with a large diameter and fixing hole 3b with a small diameter, can be provided. The diameter of fixing hole 3 is preferably approximately 5 to 10 millimeters. For example, fixing hole 3a can be designed to have a diameter of 9 millimeters, and fixing hole 3b can be designed to have a diameter of 6 millimeters. In the embodiment of the present disclosure, fixing hole 3b is smaller than fixing hole 3a, but fixing hole 3b does not have to be provided even if the two holes are the same size as long as the shape allows the decorative board base material 1 to be fixed to the existing wall 31.

[0016] The support portion 7 has a plurality of protrusions 9 formed by raising a portion of the support portion 7, in a roughly rectangular shape with the long sides parallel to the fixing surface 2, with a first protrusion 9a provided on the fixing surface 2 side and a second protrusion 9b on the inclined portion 8 side. The first protrusion 9a is provided on the fixing surface 2 side of a position that bisects the support portion 7 in the second direction, and the second protrusion 9b is provided on the inclined portion 8 side of the position that bisects the support portion 7 in the second direction. Furthermore, a notch 10 is provided in approximately the center of the second protrusion 9b on the fixing surface 2 side, and is formed in a position that will overlap with the protrusion 29 when the decorative plate 21 is attached, thereby preventing rattling of the decorative plate 21 after it has been attached. The convex portion 9 can be formed in any other way as long as the shape allows the leg portion 23 to be sufficiently engaged with the mounting portion 5, such as by cutting it out and raising it as shown in Figure 9 (Figure 9(a)), by providing a through hole 12 larger than the convex portion 9 (Figure 9(b)), by providing a bridging portion 13 between the convex portions 9 (Figure 9(c)), or by press-molding it from the back surface of the support portion 7 and forming it bulky without providing a through hole 12 or the like (Figure 9(d)).

[0017] The inclination of the inclined portion 8 is preferably inclined toward the opposing support portion 7 so that the decorative plate 21 can be easily guided when attached.

[0018] FIG. 2 shows a decorative plate 21 according to the present invention, which includes a decorative surface 22 that is generally square in front view and legs 23 extending approximately vertically from the four sides of the decorative surface 22. The legs 23 are provided with a long hole 24, a center hole 25, small holes 26, a recess 27, a cutout 28, and an outer edge 30. The center hole 25 and the recess 27 are positioned symmetrically with respect to the center line of FIG. 2(a). Similarly, the long hole 24, small holes 26, and cutout 28 are positioned symmetrically with respect to the center line of FIG. 2(b). The legs 23 may be provided with protrusions 29 on the long holes 24 to prevent rattling when the decorative plate 21 is attached to the decorative plate base material 1.

[0019] Furthermore, the decorative plate 21 can be attached to the decorative plate base material 1 by rotating it along its central axis by 0 degrees, 90 degrees, 180 degrees, or 270 degrees. This allows various patterns of design to be expressed depending on the orientation of the decorative plate 21. Therefore, although it is preferable that the legs 23 be provided on all four sides, attachment to the decorative plate base material 1 is possible as long as they are provided on at least two sides.

[0020] The decorative plate base material 1 and the decorative plate 21 are preferably formed from aluminum or the like, but may also be formed from iron, copper, stainless steel, aluminum, titanium, aluminum-zinc alloy plated steel plate, plastic resin, vinyl chloride resin, polycarbonate resin, ABS resin (a resin made from a combination of acrylonitrile, butadiene, and styrene), etc. The plate thickness is preferably about 0.5 to 2.0 mm, and can be freely designed depending on the material.

[0021] FIG. 3 shows the decorative board base material 1 of the present invention being attached to an existing wall 31 using fasteners 32. Depending on the material of the existing wall 31, fasteners 32 with a diameter of approximately 3.0 to 7.0 mm can be used. Examples of suitable fasteners include wood screws, gypsum board screws, plywood screws, hardwood screws, light-weight ceiling screws, steel frame drill screws, concrete screws, screws for autoclaved lightweight aerated concrete (ALC), and tapping screws. For outdoor use, fasteners 32 with gaskets may be used to prevent rainwater from seeping in. The gaskets may be made of, for example, ethylene propylene diene rubber (EPDM). The fixing holes 3 can be adjusted to fit the diameter of the fasteners 32. Because the mounting portions 5 of the decorative board base material 1 are symmetrically positioned in the first direction, there is no need to consider the orientation when attaching the decorative board base material 1 to the existing wall 31. In addition, in the embodiment of the present disclosure, the mounting portions 5 are attached at the top and bottom in the first direction, but since the decorative plate base material 1 is approximately square when viewed from the front, it can also be rotated 90 degrees as shown in Figure 10 and attached to the existing wall 31 so that the mounting portions 5 are on the left and right in the third direction.

[0022] When the decorative plate 21 is attached, the periphery 4 of the decorative plate base material 1 has approximately the same size in the first and third directions, so there is no risk of either the decorative plate base material 1 or the decorative plate 21 protruding when viewed from the front. Therefore, when attaching the decorative plate base material 1 to an existing wall 31, there is no need to consider the size of the decorative plate 21, making it easy to attach. For example, if you want to attach the decorative plate 21 in a straight line, you can attach the first decorative plate base material 1 to the existing wall 31, and then the second decorative plate base material 1 can be attached in a straight line by aligning the positions of the periphery 4 in the first and third directions and abutting them together.

[0023] Figure 4 shows the process of attaching the decorative plate 21, and Figure 5 shows a plan view of the completed attachment. The decorative plate 21 is attached to the decorative plate base material 1 by pressing the decorative plate 21. The decorative plate base material 1 and the decorative plate 21 are each made of an elastic material, and a notch 11 is provided between adjacent surrounding portions 4, so even if the mounting portion 5 and the leg portion 23 deform inward, interference that occurs during deformation can be suppressed. Furthermore, after attachment of the decorative plate 21 is complete, the decorative plate base material 1 and the decorative plate 21 can be firmly attached due to the mutual elastic deformation of each other.

[0024] More specifically, when the decorative plate 21 is pressed toward the decorative plate base material 1, the first protrusion 9a abuts against the outer edge 30, and the second protrusion 9b engages with the elongated hole 24. The abutment of the first protrusion 9a and the outer edge 30 acts as a barrier to prevent the decorative plate 21 from going beyond the first protrusion 9a. Furthermore, the notch 10 provided in the second protrusion 9b prevents interference with the protrusion 29, preventing rattling of the decorative plate 21 after installation. It is preferable that the protrusion 9 be raised to a height approximately equal to the thickness of the decorative plate 21 (approximately 0.2 to 3 mm), but it can be outside this range as long as it can secure the decorative plate 21 in place.

[0025] 6 shows a side view and a perspective view of a molding 61 used in the present invention. The molding 61 has a contact surface 62, a decorative surface 63, an outer surface 64, a sloped surface 65, and a fixed surface 66. The molding 61 is made of materials such as iron, copper, stainless steel, aluminum, titanium, aluminum-zinc alloy plated steel sheet, plastic resin, vinyl chloride resin, polycarbonate resin, ABS resin (a resin made by combining acrylonitrile, butadiene, and styrene), etc., which are extruded, or manufactured by processing wood, etc.

[0026] FIG. 7 shows the process of attaching the molding 61, with the contact surface 62 abutting the leg portion 23 of the decorative plate 21 and the fixing surface 66 abutting the molding portion 4 of the decorative plate base material 1, and they are attached using a fixing device 67. The fixing device 67 is used for the fixing surface 66 and is preferably made of stainless steel. When attaching the decorative plate 21 outdoors, the fixing device 67 may be equipped with a gasket to prevent rainwater from entering. The gasket is made of, for example, ethylene propylene diene rubber (EPDM). The position at which the fixing device 67 is used is arbitrary and can be changed as appropriate depending on the length of the molding 61.

[0027] Figure 8 shows examples of various mounting patterns for the decorative plate 21. Figure 8(a) shows an example in which all the decorative plates 21 are aligned, Figure 8(b) shows an example in which the decorative plates 21 are oriented randomly, Figure 8(c) shows an example in which another embodiment of the decorative plate 21 is used, and Figure 8(d) shows an example in which only one decorative plate 21 is used. The decorative plate base material 1 and the decorative plate 21 can be mounted individually as desired, allowing for a wide variety of designs to be created by combining them in different ways.

[0028] Figure 9 shows another embodiment of the decorative plate base material 1. The protrusions 9 may be formed by notching or cutting out the support portion 7 as shown in Figures 9(a), 9(b), and 9(c), or by pressing the support portion 7 from its back side to make a portion of the support portion 7 protrude, as shown in Figure 9(d). Furthermore, when a decorative plate 21 is attached to the decorative plate base material 1, it is preferable for the leg portion 23 to fit between the first protrusion 9a and the second protrusion 9b, as shown in Figure 5. Therefore, it is ideal for the distance between the first protrusion 9a and the second protrusion 9b to be approximately the same as the distance from the elongated hole 24 of the leg portion 23 to the outer edge 30.

[0029] The protrusion 9 is preferably raised to approximately the same thickness as the decorative plate 21 so that it does not protrude from the elongated hole 24 toward the molding 61 when the decorative plate 21 is attached.

[0030] Figure 10 shows an embodiment in which the decorative plate base material 1 is rotated 90 degrees from the embodiment in Figure 3. Even in this case, once the location of the first decorative plate base material 1 is determined, the second and subsequent decorative plate base materials can be attached to the wall surface 31 by abutting their surrounding parts 4 against each other, making positioning easy without having to mark out the base material.

[0031] Figure 11 shows another embodiment of the decorative plate 21. To attach the decorative plate 21 to the decorative plate base material 1, the elongated holes 24 must engage with the first protrusions 9b. Therefore, the shape of the elongated holes 24 can be freely designed as long as they can engage with the first protrusions 9b. Furthermore, as long as the legs 23 extending from the four sides of the decorative surface 22 can maintain a point-symmetric shape with respect to the central axis, it is possible to eliminate the central holes 25, small holes 26, and recesses 27, and further design the cutouts 28 as small as possible, as shown in Figure 11(b).
