[0024] A preferred embodiment of the wall panel unit according to the present invention will be described in detail below with reference to the accompanying drawings. The technical scope of the present invention is not limited to the embodiment shown in the accompanying drawings, and appropriate modifications are possible within the scope of the claims. Furthermore, the accompanying drawings are conceptual diagrams, and the relative dimensions of each component do not limit the present invention. Furthermore, in this specification, for the purpose of explaining the invention, the top and bottom may be referred to based on the top and bottom of the drawings, but this does not limit the top and bottom in relation to the wall panel unit of the present invention. In the following description of the embodiment and the accompanying drawings, similar components will be designated by the same reference numerals, and redundant explanations will be omitted.

[0025] <<First embodiment>> Figures 1 to 5 are explanatory diagrams illustrating a wall panel unit 100 according to a first embodiment. Figure 1 is an explanatory diagram showing how a panel body 10 is attached to a wall surface W. Figure 2 is an explanatory diagram showing how the panel body 10 is attached to the wall surface W. Figure 3 is a cross-sectional view of the panel body 10 being attached to the wall surface W. Figure 4 is a cross-sectional view of the panel body 10 being attached to the wall surface W. Figure 5 is an explanatory diagram showing how a plurality of panel bodies 10 are attached to the wall surface W.

[0026] The wall panel unit 100 according to the first embodiment includes a fixing body 20 that is provided between a wall surface W and a panel body 10 and that can fix the panel body 10 to the wall surface W.

[0027] The wall panel unit 100 according to the present invention may include the panel body 10. That is, the wall panel unit 100 according to the present invention includes a form including the panel body 10 installed on the wall surface W and a fixing body 20 that fixes the panel body 10 to the wall surface W.

[0028] The panel body 10 can naturally be adopted as long as it is a panel-shaped object that is installed on the wall surface W. That is, examples of the panel body 10 include a wooden board, a metal board, a tile board, a synthetic resin, wallpaper, a board with wallpaper attached, a board with other wall materials, an advertising board, a guide board, an interior item, an art piece, and the like.

[0029] The panel body 10 may also be made of a flexible material. When arranging the wall panel units 100, such as when arranging the panel body 10 on the wall surface W without any gaps, the panel body 10 itself deforms, making it easy to attach and detach the panel body 10. An example of a flexible panel body 10 is a metal plate.

[0030] 1 to 5 show a square panel body 10, but any shape that can be used as a wall panel can be used. Examples of the shape of the panel body 10 include a square, a rectangle, a trapezoid, a triangle, and other regular polygons.

[0031] The fixed body 20 has a first fixed body 21 fixed to the panel body 10, a second fixed body 22 fixed to the wall surface W and connected to the first fixed body 21, and a connection portion 23 connecting the first fixed body 21 and the second fixed body 22.

[0032] The first fixed body 21 has a first support portion 211 fixed to the panel body 10 and supporting the panel body 10 from the back surface 12 side, an abutment surface 212 abutting against the wall surface W, and a connection portion 213 connected to the second fixed body 22.

[0033] Naturally, any means commonly used in the construction industry can be used as the fixing means for the first fixing body 21. That is, examples of the fixing means include adhesive, bolts, screws, nails, double-sided tape, etc.

[0034] The second fixed body 22 has a second support portion 221 that abuts against the panel body 10 and supports the panel body 10 from the rear surface 12 side, a fixing surface 222 that is fixed to the wall surface W, and a connecting portion 223 that is connected to the first fixed body 21. Note that the fixing means for this second fixed body 22 can be the same as the fixing means for the first fixed body 21.

[0035] Any known means can be used for the connecting portion 23 as long as it can connect the second support portion 221 so that it abuts against the rear surface 12 of the panel body 10. Note that in the first embodiment, Figures 1 to 5 show a form in which the first fixed body 21 and the second fixed body 22 are formed with inclined surfaces and are engaged with each other to fix the panel body 10 to the wall surface W. Other means that can be used include, for example, a means of fitting together a recess and a protrusion, or a means of fitting by sliding the second fixed body 22 from the side.

[0036] Furthermore, it is desirable that the fixed body 20 have a support region 24 that supports the entire back surface 12 of the panel body 10. This support region 24 is a region that includes the first support portion 211 and the second support portion 221. In this way, by having the support region 24 of the fixed body 20 support the entire back surface 12 of the panel body 10, it is possible to increase the stability when the panel body 10 is installed on the wall surface W.

[0037] Furthermore, it is desirable that the outer edge of the fixing body 20 coincides with the outer edge of the panel body 10. In other words, it is desirable that the rear surface 12 of the panel body 10 coincides with the support region 24 when the first fixing body 21 and the second fixing body 22 are connected. By thus aligning the outer edges of the fixing body 20 and the panel body 10, it is possible to arrange multiple panel bodies 10 without any gaps, as shown in FIG. 5 .

[0038] It is also desirable that the first fixed body 21 and the second fixed body 22 have the same shape. In this way, since the first fixed body 21 and the second fixed body 22 have the same shape, there is no need to manufacture them in separate processes, and manufacturing costs can be reduced.

[0039] According to the present invention, the panel body 10 is fixed to the wall surface W by connecting the first fixing body 21 fixed to the panel body 10 and the second fixing body 22 fixed to the wall surface W. Therefore, the panel body 10 can be installed regardless of the shape or material of the panel body 10, and various panel bodies 10 can be installed on the wall surface W.

[0040] Second Embodiment A wall panel unit 200 according to a second embodiment will be described in detail below with reference to Figures 6 and 7. This second embodiment has a fixed body 20 having a different shape from that of the previous embodiment.

[0041] As shown in Fig. 6, the wall panel unit 200 according to the second embodiment includes a fixing body 20 that is provided between a wall surface W and a panel body 10 and that can fix the panel body 10 to the wall surface W. The fixing body 20 also includes a first fixing body 21 that is fixed to the panel body 10, and a second fixing body 22 that is fixed to the wall surface W and connected to the first fixing body 21.

[0042] The wall panel unit 200 may include the panel body 10. That is, the wall panel unit 100 according to the present invention includes a form including the panel body 10 installed on the wall surface W and a fixing body 20 that fixes the panel body 10 to the wall surface W.

[0043] The first fixed body 21 in the second embodiment has a first support portion 211 fixed to the panel body 10 and supporting the panel body 10 from the back surface 12 side, an abutment surface 212 abutting against the wall surface W, a first inclined portion 214 (corresponding to the connection portion 213 in the previous embodiment) connected to the second fixed body 22, and a second inclined portion 215 provided on the opposite side of the first inclined portion 214 and inclined at the same angle as the first inclined portion 214.

[0044] The second fixed body 22 in the second embodiment has a second support portion 221 that abuts against the panel body 10 and supports the panel body 10 from the back surface 12 side, a fixed surface 222 that is fixed to the wall surface W, a first inclined portion 224 (corresponding to the connection portion 223 in the previous embodiment) that is connected to the first fixed body 21, and a second inclined portion 225 that is provided on the opposite side of the first inclined portion 224 and is inclined at the same angle as the first inclined portion 224.

[0045] That is, according to this embodiment, first inclined portions 214, 224 are provided at the connection portion 23 between the first fixed body 21 and the second fixed body 22, and second inclined portions 215, 225 inclined at the same angle as the first inclined portions 214, 224 are provided on the opposite side of the connection portion 23 between the first fixed body 21 and the second fixed body 22.

[0046] 7 is an explanatory diagram showing how the wall panel unit 200 according to this embodiment is installed on a wall surface W. By providing the second inclined portions 215, 225 inclined at the same angle as the first inclined portions 214, 224, the first fixed body 21 can be connected to the second fixed body 22 along the inclined angle. As a result, the wall panels can be arranged without gaps in the vertical direction.

[0047] Third Embodiment A wall panel unit 300 according to a third embodiment will now be described in detail with reference to Fig. 8. This third embodiment has a fixing body 20 with a different shape from that of the previous embodiment. Note that in this embodiment, components that are basically the same as those in the previous embodiment will be assigned the same reference numerals and their description will be simplified.

[0048] 8, the wall panel unit 300 according to the third embodiment includes a fixing body 20 that is provided between a wall surface W and a panel body 10 and that can fix the panel body 10 to the wall surface W. The fixing body 20 also includes a first fixing body 21 that is fixed to the panel body 10, and a second fixing body 22 that is fixed to the wall surface W and connected to the first fixing body 21.

[0049] The wall panel unit 300 may include the panel body 10. That is, the wall panel unit 100 according to the present invention includes a form including the panel body 10 installed on the wall surface W and a fixing body 20 that fixes the panel body 10 to the wall surface W.

[0050] The first fixed body 21 in the third embodiment has a first support portion 211 fixed to the panel body 10 and supporting the panel body 10 from the back surface 12 side, an abutment surface 212 abutting against the wall surface W, a first horizontal portion 216 (corresponding to the connection portion 213 in the previous embodiment) connected to the second fixed body 22, and a second horizontal portion 217 provided on the opposite side of the first horizontal portion 216.

[0051] The second fixed body 22 in the third embodiment has a second support portion 221 that abuts against the panel body 10 and supports the panel body 10 from the back surface 12 side, a fixed surface 222 that is fixed to the wall surface W, a first horizontal portion 226 (corresponding to the connection portion 223 in the previous embodiment) that is connected to the first fixed body 21, and a second horizontal portion 227 that is provided on the opposite side of the first horizontal portion 226.

[0052] That is, according to this embodiment, first horizontal portions 216, 226 are provided at the connection portion 23 between the first fixed body 21 and the second fixed body 22, and second horizontal portions 217, 227 are provided on the opposite side of the connection portion 23 between the first fixed body 21 and the second fixed body 22.

[0053] According to this embodiment, the connection portion 23 between the first fixed body 21 and the second fixed body 22 is formed horizontally. By forming the connection portion 23 horizontally in this way, it can be fitted vertically into the wall surface, as shown in FIG. 8 . This is useful in situations where ease of attachment and detachment is more important than safety, such as temporary use scenes such as the wall of an exhibition booth, or a studio or stage set. Furthermore, the panel body 10 can be easily arranged over the entire wall surface W.

[0054] <Fourth embodiment> A wall panel unit 400 according to a fourth embodiment will be described in detail below with reference to Figures 9 to 11. This fourth embodiment has an auxiliary fixing body 25 in addition to a first fixing body 21 and a second fixing body 22. In this embodiment, components that are basically the same as those in the previous embodiment are given the same reference numerals, and their description will be simplified.

[0055] 9 is an explanatory diagram illustrating the configuration of a wall panel unit 400 according to the fourth embodiment. In this Figure 9, an auxiliary fixing body 25 is installed on the panel body 10 side.

[0056] Similar to the previous embodiments, the wall panel unit 400 according to the fourth embodiment includes a fixing body 20 that is provided between a wall surface W and a panel body 10 and can fix the panel body 10 to the wall surface W. The fixing body 20 includes a first fixing body 21 that is fixed to the panel body 10, a second fixing body 22 that is fixed to the wall surface W and connected to the first fixing body 21, and an auxiliary fixing body 25 that assists in connecting the first fixing body 21 and the second fixing body 22.

[0057] The first fixed body 21 is provided, and on its end face opposite the connection portion 23, it has an inclined surface 218 (corresponding to the second inclined portion 215 in the third embodiment) that slopes from the outside to the inside of the panel body 10 toward the wall surface W, and a parallel surface 219 (corresponding to the second horizontal portion 217 in the third embodiment) that is parallel to the end face of the auxiliary fixed body 25 described later.

[0058] The second fixing body 22 has, on its end face opposite the connection portion 23, an inclined surface 228 (corresponding to the second inclined portion 225 in the third embodiment) that slopes from the outside of the panel body 10 toward the inside of the panel body 10, and a parallel surface 229 (corresponding to the horizontal portion 237 in the third embodiment) that is parallel to the end face 253 of the auxiliary fixing body 25 described later.

[0059] The auxiliary fixing body 25 has a support portion 251 that is fixed to the panel body 10 and supports the panel body 10 from the back surface 12 side, an abutment surface 252 that abuts against the wall surface W, and an end surface 253 that is close to the second fixing body 22 (or the first fixing body 21).

[0060] FIG. 10 is an explanatory diagram showing the installation of the panel body 10 of the fourth embodiment on a wall surface W. FIG. 10( a) is an explanatory diagram showing the state in which the first fixed body 21 and the second fixed body 22 are separated. As shown in FIG. 10( a), the minimum distance between the first fixed body 21 and the auxiliary fixed body 25 is shorter than the maximum vertical length of the second fixed body 22. This prevents the panel body 10 from being attached or detached when the panel body 10 is parallel to the wall surface W. The minimum distance between the first fixed body 21 and the auxiliary fixed body 25 is the distance from the tip of the first inclined portion 214 of the first fixed body 21 to the end face 253 of the auxiliary fixed body 25. The maximum vertical length of the second fixed body 22 is the sum of the vertical length of the second support portion 221 and the vertical length of the inclined surface 228.

[0061] 10(b) is an explanatory diagram showing the initial connection state of the panel body 10. In this initial connection state, the upper end of the panel body 10 is tilted toward the wall surface W, and the first inclined portion 214 of the first fixed body 21 is brought into contact with the first inclined portion 224 of the second fixed body 22. The length from the tip of the first inclined portion 214 of the first fixed body 21 to the end face 253 of the auxiliary fixed body 25 is configured to be approximately the same as or slightly longer than the vertical length of the second support portion 221 of the second fixed body 22. As a result, by hooking the tip of the first inclined portion 214 of the first fixed body 21 onto the tip of the first inclined portion 224 of the second fixed body 22, the end face 253 of the auxiliary fixed body 25 can be moved closer to the wall surface W from the inclined surface 228 of the second fixed body 22.

[0062] 10(c) is an explanatory diagram showing the state of the panel body 10 in a later stage of connection. In this later stage of connection, the second fixed body 22 is inserted between the first fixed body 21 and the auxiliary fixed body 25 by sliding the panel body 10 along the slope of the first inclined portions 214, 224 and changing the inclination angle of the panel body 10 so that the lower end of the panel body 10 approaches the wall surface W. At this time, the inclined surface 218 of the first fixed body 21 allows the first fixed body 21 to approach the wall surface W, thereby connecting the first fixed body 21 and the second fixed body 22. Here, the inclined surface 228 is formed to come into contact with the corner of the auxiliary fixed body 25 when the first fixed body 21 comes into contact with the wall surface W.

[0063] 10(d) is an explanatory diagram showing the first fixed body 21 and the second fixed body 22 connected together. In this connected state, the end surface 253 of the auxiliary fixed body 25 faces the parallel surface 229 formed on the end surface of the second fixed body 22, preventing the connection from being easily released. In other words, to remove the panel body 10, it is necessary to change the inclination angle of the panel body 10 so that the lower end of the panel body 10 moves away from the wall surface W, while sliding the panel body 10 along the inclination of the first inclined portion 224 of the second fixed body 22. Furthermore, in the connected state, the inclined surface 218 of the first fixed body 21 is provided so as to leave a gap between it and the wall surface W, and the inclined surface 228 of the second fixed body 22 is provided so as to leave a gap between it and the panel body 10.

[0064] According to this embodiment, the auxiliary fixing member 25 is further provided, thereby limiting the range of movement (movement route) of the panel body 10 during attachment and detachment, thereby preventing the panel body 10 from being easily disconnected from the wall surface W. In other words, the panel body 10 is attached to the wall surface W by sliding and tilting it in the order of FIGS. 10( a), 10( b), 10( c), and 10( d), and is removed from the wall surface W by tilting it in the order of FIGS. 10( d), 10( c), 10( b), and 10( a). The panel body 10 can also be removed by sliding it in the width direction of the first fixing member 21. In this way, by configuring the panel body 10 so that it can only be detached along a specific movement route during attachment and detachment, it is possible to prevent the panel body 10 from falling due to an earthquake or being removed by a malicious third party.

[0065] Fig. 11 illustrates an example in which auxiliary fixing body 25 of this embodiment is arranged on the wall surface W side. As shown in Fig. 11, even in the example in which auxiliary fixing body 25 is arranged on the wall surface W side, the same effect as in the example in which auxiliary fixing body 25 is arranged on panel body 10 is achieved. That is, since parallel surface 219 of first fixing body 21 faces end surface 253 of auxiliary fixing body 25, the movement route of panel body 10 can be restricted.

[0066] 10 and 11 show an example in which the notch is provided in first fixed body 21, but the notch may be provided in auxiliary fixed body 25, or in both first fixed body 21 and auxiliary fixed body 25. In other words, by providing a notch in the end face of auxiliary fixed body 25, auxiliary fixed body 25 can be inserted smoothly.

[0067] Fifth Embodiment A wall panel unit 500 according to a fifth embodiment will now be described in detail with reference to Figures 12 to 17. In this fifth embodiment, the first fixing body 21 has a plurality of fixing body pieces 26. In this embodiment, components that are basically the same as those in the previous embodiment are given the same reference numerals, and their description will be simplified.

[0068] 12 to 17 are explanatory diagrams illustrating a wall panel unit 500 according to a fifth embodiment and modifications thereof. Fig. 12(a) is a perspective view of the wall panel unit 500 according to the fifth embodiment attached to a wall surface W, as viewed from the front. Fig. 12(b) is a perspective view of the wall panel unit 500 according to the fifth embodiment attached to a wall surface W, as viewed from the rear. Fig. 13 is an explanatory diagram illustrating the configuration of the wall panel unit 500 according to the fifth embodiment.

[0069] As in the previous embodiments, the wall panel unit 500 according to the fifth embodiment includes a fixing body 20 that is provided between a wall surface W and the panel body 10 and can fix the panel body 10 to the wall surface W. The fixing body 20 has a first fixing body 21 that is fixed to the panel body 10, and a second fixing body 22 that is fixed to the wall surface W and connected to the first fixing body 21.

[0070] The first fixed body 21 has a plurality of fixed body pieces 26, which are arranged to form two or more connection grooves 27 connectable to the second fixed body 22. That is, as an example of a wall panel unit 500 according to the fifth embodiment, as shown in Figures 12 to 15, two square fixed body pieces 26 are arranged in the vertical and horizontal directions of the panel body 10 (four in total), aligned with the corners of the panel body, thereby forming two cross-shaped connection grooves 27.

[0071] Here, the second fixed body 22 is longer than the length of one side of the fixed body piece 26, so that it can be attached to multiple fixed body pieces 26. In this embodiment, the thickness of the fixed body piece 26 is 8 mm to 15 mm, and the size of the panel body 10 or the distance between the outer edges of the fixed body pieces 26 is assumed to be 70 mm to 90 mm on one side, but is preferably 100 mm or more. In addition, the width of the connecting groove 27 and the second fixed body 22 is preferably 40 mm or more. This makes it possible to make the gap between the first fixed body 21 and the second fixed body 22 smaller than the overall size, thereby reducing rattling.

[0072] Figure 14 is an explanatory diagram illustrating the fixed body piece 26. Figure 14(a) is a plan view of one fixed body piece 26. Figure 14(b) is a cross-sectional view taken along line A-A' in Figure 14(a). Figure 14(c) is a cross-sectional view taken along line B-B' in Figure 14(a). Figure 14(d) is a rear view showing the fixed body piece 26 arranged on the panel body 10.

[0073] The fixed body piece 26 is a solid piece formed in a parallelepiped shape, and has a first support portion 261 that is fixed to the panel body 10 and supports the panel body 10 from the back surface 12 side, an abutment surface 262 that abuts against the wall surface W, a connection portion 263 that connects to the second fixed body 22, an inclined surface 264 that slopes from the outside to the inside of the panel body 10, and a flat surface 265 that is perpendicular to the wall surface W.

[0074] Similar to the inclined surface 218 in the fourth embodiment, the inclined surface 264 can prevent interference between the fixing piece 26 and the wall surface W when the panel body 10 is tilted. Therefore, similar to the fourth embodiment, the panel body 10 can be attached to the wall surface W by sliding and tilting the panel body 10.

[0075] The fixing body pieces 26 are arranged on the panel body 10 so that the connecting portions 263 face each other. As a result, as shown in Figure 15, the fixing body piece 26 located above the second fixing body 22 functions as the first fixing body 21, and the fixing body piece 26 located below the second fixing body 22 functions as the auxiliary fixing body 25, allowing for fitting in the same manner as in the fourth embodiment. In particular, it is preferable that the inclined surface 228 is formed so that when the upper fixing body piece 26 comes into contact with the wall surface W, the upper end of the lower fixing body piece 26 comes into contact with the inclined surface 228.

[0076] The connecting grooves 27 can be formed by arranging multiple fixing pieces 26 at intervals on the panel body 10. While Figures 12 to 14 illustrate a configuration in which two connecting grooves 27 are arranged in a cross shape, three or more connecting grooves 27 may be formed as shown in Figure 15. Figure 16(a) shows an example in which three triangular connecting grooves 27 are formed by arranging triangular fixing pieces 26 at intervals on the panel body 10. Figure 16(b) shows an example in which three asterisk-shaped connecting grooves 27 are formed by arranging diamond-shaped fixing pieces 26 at intervals on the panel body 10.

[0077] Also, as shown in Figure 17, the wall panel unit 500 may be arranged with a distance between the side end of the panel body 10 and the fixed body piece 26, and a mounting body 3 may be placed on top of the fixed body piece 26.

[0078] The mounting body 3 is a solid piece provided independently from the panel body 10 so as to have a thickness approximately equal to that of the fixed body piece 26. As shown in FIG. 17(c), the mounting body 3 is inclined so that its lower surface abuts against the inclined surface 264. The lower surface may be horizontal so that it can be placed on a flat surface 265. Furthermore, the mounting body 3 is provided so that its height is approximately equal to the distance from the upper end of the abutment surface 262 to the side of the panel body 10, making it invisible in a front view as shown in FIGS. 17(a) and 17(b). After installing the panel body 10 on the wall surface W, a user can place the panel body 10 on the fixed body piece 26 by inserting the mounting body 3 into the gap between the panel body 10 and the wall surface W. This prevents the mounting body 3 from interfering with tilting, thereby preventing malicious removal.

[0079] In addition, although the width of the mounting body 3 is set to be approximately the same as that of the fixed body piece 26 in Figure 17, it is preferable that the width be at least larger than the width of the connecting groove 27, and it may also be expanded to be approximately the same as that of the panel body 10.

[0080] 18(a), the mounting body 3 may have a cross section with the same shape as the second fixed body 22, and a bottom surface with a shape corresponding to that of the second fixed body 22. This allows the mounting body 3 to penetrate the connecting groove 27 and be placed on the second fixed body 22, thereby increasing the stability of the mounting body 3. Furthermore, as shown in FIG. 18(b), the mounting body 3 may be formed in a U-shape, surrounding the fixed body piece 26 from three directions, and placed on the second fixed body 22 and the fixed body piece 26, which further increases stability.

[0081] In addition, when the panel bodies 10 are provided adjacent to each other vertically, it is preferable that the height of the mounting body 3 is greater than the distance from the upper end of the abutment surface 262 to the side surface of the panel body 10. In this configuration, tilting is suppressed at the upper part of the panel body 10 by interference from the mounting body 3 placed on the fixed body piece 26, and further tilting is suppressed at the lower part of the panel body 10 by interference from the mounting body 3 protruding from the adjacent panel body 10, so tilting does not occur in either the vertical direction and malicious removal can be prevented.

[0082] According to this embodiment, by forming two or more connecting grooves 27, the angle at which the panel body 10 is attached and detached can be changed. That is, when two connecting grooves 27 are formed in a cross shape, the panel body 10 can be fixed to the wall surface W by rotating it by 90 degrees. Furthermore, when the connecting grooves 27 are formed in a triangular shape as shown in FIG. 15( a) or an asterisk shape as shown in FIG. 15( b), the panel body 10 can be fixed to the wall surface W by rotating it by 60 degrees. In this way, by changing the orientation of the panel body 10, it is possible to enjoy various variations in the design of the wall panel.

[0083] Sixth Embodiment A wall panel unit 600 according to a sixth embodiment will be described in detail below with reference to Fig. 18. As shown in Fig. 19(a), in addition to the configuration of the fourth embodiment, this sixth embodiment has a surface fixing body 28 connected to the first fixing body 21 on the surface of the panel body 10 opposite the surface on which the first fixing body 21 is provided. In this embodiment, components that are basically the same as those in the previous embodiments are assigned the same reference numerals, and their description will be simplified.

[0084] The surface fixing body 28 is a fixing body having substantially the same shape as the second fixing body 22. When attached to the wall surface W, it is attached or mounted to the surface of the panel body 10 so as to be parallel to the second fixing body 22 and at substantially the same height as the second fixing body 22. The surface fixing body 28 makes it possible to attach another panel body 10 to the surface of the panel body 10, as shown in Figure 19(b), and the height of the installed panel body 10 can be freely adjusted. In other words, it makes it possible to express unevenness and make it applicable to various wall panels.

[0085] Furthermore, although not shown, the upper and / or lower surfaces of the second fixing body 22 in the first to sixth embodiments may be provided with a plurality of protrusions spaced at intervals wider than at least the first fixing body 21 or fixing body piece 26. This prevents removal of the panel body 10 by sliding it in the width direction and improves the attachment strength. The protrusions may be formed by driving nails or attaching metal fittings.

[0086] The thickness of the fixing body 20 in the above-described embodiments 1 to 6 can be 10 mm or less. In particular, in embodiments 1 to 3, the entire surface of the panel body 10 is supported, so that stable support is possible even if the thickness is 3 mm to 7 mm.
