Description

[Technical Field]

[0001] The present invention relates to a detachable wall panel piece and a detachable wall panel. More specifically, the present invention relates to a detachable wall panel piece that can be easily and detachably attached to an existing wall surface, and a detachable wall panel that uses a plurality of such detachable wall panel pieces. [Background technology]

[0002] As described in Patent Documents 1 to 6, detachable wall panels are known that can be easily attached to and detached from existing wall surfaces using hook-and-loop fasteners such as Magic Tape (registered trademark). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3168716 [Patent Document 2] Japanese Patent Application Publication No. 10-169155 [Patent Document 3] Japanese Patent Application Laid-Open No. 2011-042961 [Patent Document 4] Utility Model Registration No. 3175888 [Patent Document 5] Patent No. 6422135 [Patent Document 6] Japanese Patent Application Publication No. 9-96081 Summary of the Invention [Problem to be solved by the invention]

[0004] The detachable wall panels described in Patent Documents 1 to 5 can be easily attached and detached to an existing wall surface, making it easy to rearrange the wall, but the entire surface of the detachable wall panel comes into direct contact with the existing wall surface.

[0005] However, there are cases where wiring such as power cords runs vertically or horizontally on the wall, or where you want to run wiring. Especially in older houses, there are often only a few outlets in the wall to begin with, and in rented houses, for example, it is difficult to drill holes in the existing wall, so extension cords are often extended from the existing outlets. Such wiring is often left exposed and running on the wall, or housed in a wiring mall and fixed to the wall.

[0006] When installing wiring on a wall in this manner, with detachable wall panels such as those described in Patent Documents 1 to 5, there is no gap for wiring between the existing wall and the wall panel, so it is not possible to install wiring on the back side of the detachable wall panel (on the side facing the existing wall) and hide the wiring.

[0007] In this regard, in the case of a detachable wall panel such as that described in Patent Document 6, a protrusion (20) (provided on the base material 20) is present between the existing wall surface (base material 20) and the detachable wall panel (interior wall material body 11), so a gap is formed between the existing wall surface and the detachable wall panel, and it is possible to use this gap to place wiring on the back side of the detachable wall panel. However, in the case of a detachable wall panel such as that described in Patent Document 6, a protrusion is required on the existing wall surface.

[0008] Therefore, the purpose of this invention is to provide a detachable wall panel piece and a detachable wall panel that do not require a protrusion on the existing wall surface, and that allow wiring to be installed and hidden between the existing wall surface and the detachable wall panel. [Means for solving the problem]

[0009] In order to achieve the above-mentioned objective, the detachable wall panel piece of the present invention is a detachable wall panel piece that can be detachably attached to an existing wall surface, and is characterized in that it consists of a panel piece main body, a flat base attached to the back side of the panel piece main body, and a detachable material provided on the existing wall surface side of the flat base, and the area of ​​the flat base is smaller than the area of ​​the panel piece main body.

[0010] The detachable wall panel of this invention allows for a space without a flat base to be formed on the back side of the panel piece itself. In other words, a recess corresponding to the thickness of the flat base is formed on the back side of the panel piece itself. Therefore, when attaching multiple panel pieces to an existing wall, this recess can be used to house wiring.

[0011] In addition, in the detachable wall panel piece of the present invention, it is preferable that the area of ​​the flat base is 70.0 to 90.0% of the area of ​​the panel piece body. With the detachable wall panel piece of this invention, even if the detachable wall panel piece is cut and used, a sufficient contact area can be ensured between the flat base and the existing wall surface, and the detachable wall panel piece can be used stably without requiring an additional process such as attaching a new flat base for reinforcement purposes.

[0012] In addition, in the detachable wall panel piece of the present invention, it is preferable that the flat base is attached inside the end of the panel piece body. The detachable wall panel pieces of this invention allow for the creation of a space between adjacent detachable wall panel pieces without a flat base, in cases where multiple detachable wall panel pieces are used. In other words, a recess can be created between adjacent detachable wall panel pieces, which can be used to accommodate wiring.

[0013] In addition, it is preferable that the detachable wall panel piece of the present invention has a plurality of flat bases, and that the plurality of flat bases are attached at a distance from each other. According to the detachable wall panel piece of the present invention, a recess can be formed between adjacent flat bases, which can be used to accommodate wiring.

[0014] In addition, it is preferable that the detachable wall panel piece of the present invention has at least four flat bases, and that the flat bases are attached spaced apart in the row and column directions. The detachable wall panel pieces of this invention allow horizontal and vertical recesses to be formed between adjacent flat bases, making it easy to accommodate wiring that is routed horizontally or vertically.

[0015] The detachable wall panel of the present invention is characterized in that it is formed using a plurality of the above-mentioned detachable wall panel pieces. With the detachable wall panel of this invention, when redecorating an existing wall, wiring can be installed and hidden between the existing wall and the detachable wall panel without creating any protrusions on the existing wall.

DETAILED DESCRIPTION OF THE INVENTION

[0017] The following describes the mode for carrying out the present invention with reference to the embodiments and drawings, but the embodiments shown below are not intended to limit the present invention to those described herein, and the present invention is equally applicable to various modifications without departing from the technical idea set forth in the claims. Note that in the drawings used for explanation in this specification, each component is shown at a different scale so that it can be recognized on the drawing, and the components are not necessarily shown in proportion to their actual dimensions.

[0018] [Embodiment] Using Figures 1 to 3, we will explain the detachable wall panel piece 10 of this embodiment (hereinafter simply referred to as ``panel piece 10'' as appropriate) and the detachable wall panel 1 formed using multiple detachable wall panel pieces 10.

[0019] First, the panel piece 10 of this embodiment is used to remodel the surface of an existing wall W shown in FIG. 1A. Wiring C may, but is not always, present on such a wall W. In older houses, such wiring C may be extension cords extending from existing outlets, as there may not be many outlets in the wall to begin with. In particular, in rented houses, it is difficult to drill holes in the existing wall, so wiring C is often laid along the wall W like this. Note that in Figure 1A, the wiring C is not laid exposed on the wall W, but is housed in a wiring mall and fixed to the wall W.

[0020] The panel piece 10 and the detachable wall panel 1 can be easily attached and detached to an existing wall surface W, and the wiring C running along the existing wall surface W can also be hidden behind the panel piece 10 as shown in Figure 1B. First, details of the panel piece 10 will be described with reference to Figures 2 and 3. Figure 2A is a front view of the panel piece 10, Figure 2B is a side view, and Figure 2C is a back view. Figure 3 is a manufacturing process diagram of the panel piece 10.

[0021] The panel piece 10 is a square wooden product with sides of 450 mm. The panel piece 10 is composed of nine pattern plates 20 located on the front side, one base plate 30 to which the pattern plates 20 are fixed, and four flat bases 40 fixed to the back side of the base plate 30.

[0022] The pattern plate 20 is made of natural wood such as cedar and is a square plate with each side measuring 150 mm. The pattern plate 20 is 10 mm thick and has chamfered portions 21 that are chamfered at 45-degree angles on all four sides, giving it a trapezoidal shape in side view as shown in Figure 2B. In this embodiment, nine such pattern plates 20 are used for one panel piece 10.

[0023] The base plate 30 is a square plate with sides of 450 mm made of lauan plywood with a thickness of 2.5 mm. In this embodiment, one base plate 30 is used for one panel piece 10.

[0024] The flat base 40 is a square plate with sides of 205 mm made of lauan plywood with a thickness of 12 mm. The flat base 40 is in direct contact with the existing wall surface W of the panel piece 10. In this embodiment, four flat bases 40 are used for one panel piece 10.

[0025] As shown in Figure 3, the panel piece 10 having such a configuration is first fixed by adhesively attaching nine pattern plates 20 to the front side of the base plate 30, three in each of the row and column directions (S1). At this time, adjacent pattern plates 20 are attached so that they are in contact with each other and there are no gaps between them. Then, with the pattern plates 20 attached to the base plate 30 in this manner, the panel piece main body 11 is formed.

[0026] Next, the four flat pedestals 40 are aligned in rows and columns, two in each direction, and attached and fixed with adhesive to the rear surface of the base plate 30 of the panel piece main body 11 (S2). At this time, adjacent flat pedestals 40 are attached with a gap of 20 mm (G1 in FIG. 2C) from each other. Furthermore, the flat pedestals 40 are attached with a gap of 10 mm (G2 in FIG. 2C) from the edge of the base plate 30.

[0027] As described above, in the panel piece 10 of this embodiment, the entire back surface of the base plate 30 is not covered by the flat pedestal 40, but four flat pedestals 40 are used, and the flat pedestals 40 are attached with gaps between them. Therefore, the total area of ​​the four flat pedestals 40 is smaller than the area of ​​the panel piece main body 11, i.e., the area of ​​the base plate 30.

[0028] Finally, a hook-and-loop fastener 50 such as a Velcro tape (registered trademark) forming a detachable member is attached to the rear surface of the rear surface side of the flat base 40 (S3). In this embodiment, the hook-and-loop fasteners 50 are attached only to the two upper flat bases 40, but they may also be attached to the lower flat base 40. Also, although the hook-and-loop fasteners 50 are attached horizontally, they may also be attached vertically. Also, hook-and-loop fasteners 50 usually have a hook surface and a loop surface, but either may be selected.

[0029] Through the above steps, the panel piece 10 shown in S4 is manufactured. Then, by attaching a plurality of panel pieces 10 to the existing wall surface W shown in Figure 1A, a detachable wall panel 1 is formed on the existing wall surface W. In addition, when the hook-and-loop fastener 50 attached to the flat base 40 has a hook surface, the panel piece 10 is attached by attaching the loop-side hook-and-loop fastener to the existing wall surface W side, and when the hook-and-loop fastener 50 has a loop surface, the hook-and-loop fastener is attached to the existing wall surface W side.

[0030] In the panel piece 10 of this embodiment, flat pedestals 40 are attached to the back side of the panel piece main body 11, and the total area of ​​the four flat pedestals 40 is smaller than the area of ​​the panel piece main body 11 (the area of ​​the base plate 30). Therefore, a space without the flat pedestals 40 can be formed on the back side of the panel piece main body 11. In other words, a recess 12 corresponding to the plate thickness (12 mm) of the flat pedestal 40 is formed on the back side of the panel piece main body 11. 1B, when attaching multiple panel pieces 10 to an existing wall surface W, the wiring C can be accommodated in the recess 12. The depth of the recess 12 corresponds to the thickness (12 mm) of the flat base 40, and with this depth, the wiring C and the wiring molding that accommodates the wiring C shown in FIG. 1A can be accommodated in the recess 12. However, it goes without saying that the thickness of the flat base 40 is not limited to that of this embodiment.

[0031] Furthermore, the panel piece 10 of this embodiment is formed so that the flat base 40 is attached inside (G2) the end (end of the base plate 30) of the panel piece main body 11. Therefore, in the detachable wall panel 1 using a plurality of panel pieces 10, a space without a flat base 40 is formed between adjacent panel pieces 10, i.e., a recess 13 (between the panel pieces) of G2 × 2. Therefore, the wiring C can be accommodated in the recess 12 or the recess 13 (between the panel pieces) depending on the position of the wiring C laid on the existing wall surface W. In this embodiment, the widths of the recess 12 and the recess 13 are the same, that is, G1 = G2 × 2.

[0032] Furthermore, the panel piece 10 of this embodiment is configured such that four planar bases 40 are aligned and attached in the row and column directions, spaced apart from one another with gaps G1 between them. Therefore, in the panel piece 10, recesses 12 are formed between adjacent planar bases 40 in both the horizontal and vertical directions. Therefore, wiring C running along the existing wall surface W can be easily accommodated, regardless of whether it extends horizontally or vertically.

[0033] 1, a plurality of panel pieces 10 of this embodiment are used on an existing wall surface W to form a detachable wall panel 1. In this case, it would be ideal if all of the panel pieces 10 could be neatly attached to the existing wall surface W, but in reality, some of the panel pieces 10 often remain unused relative to the height and width of the existing wall surface W.

[0034] For example, in the detachable wall panel 1 shown in FIG. 1B, the uppermost panel piece 100A is obtained by cutting off approximately one-fifth of the upper part of the panel piece 10. In addition, in the detachable wall panel 1 shown in FIG. 1B, the right panel piece 100B is obtained by cutting off approximately one-third of the right side of the panel piece 10.

[0035] In this way, in the detachable wall panel 1, some of the panel pieces 10 used in multiple pieces may be cut and used, such as panel piece 100A and panel piece 100B. Even if the panel piece 10 of this embodiment is cut and used, such as panel piece 100A and panel piece 100B, it can be stably attached to the existing wall surface W.

[0036] This point will be explained in detail with reference to the drawings. First, as shown in Fig. 2C, four flat pedestals 40 are attached to the back side of the panel piece main body 11 on the back side of the panel piece 10. The total area of ​​these flat pedestals 40 is smaller than the area of ​​the panel piece main body 11 (the area of ​​the base plate 30).

[0037] in particular, The area of ​​each flat base 40 is 205 x 205 = 42,025 (mm 2 ) Total area of ​​the flat base 40 on the panel piece 10: 42,025 x 4 = 168,100 (mm 2 ) Area of ​​panel piece body 11: 450 x 450 = 202,500 (mm 2 ) It is as follows.

[0038] In this case, the proportion of the panel piece 10 occupied by the flat base 40 is approximately 83% in this embodiment. In this way, the proportion of the flat base 40 in the panel piece 10 is greater than half (50%). After various studies, the applicant has concluded that the proportion of the flat base 40 in the panel piece 10 is extremely important. The applicant's verification has revealed that it is preferable that the proportion of the flat base 40 in the panel piece 10 be 70.0 to 90.0%.

[0039] The panel piece 10 is preferably as lightweight as possible, since it will be attached to an existing wall surface W. Based on the idea of ​​the present invention that the area of ​​the flat base 40 is smaller than the area of ​​the panel piece main body 11 (the area of ​​the base plate 30), it is also possible to adopt a configuration such as that shown in Figures 4A and 4B.

[0040] 4A shows a panel piece 10A in which the flat base 40A on the back side is L-shaped. The panel piece 10A is configured using four of these L-shaped flat bases 40A as shown in the figure. In the panel piece 10A, the flat bases 40A account for less than half of the panel piece 10A. The hook-and-loop fasteners 50, which serve as attachment and detachment members, are attached to each flat base 40A in the horizontal direction.

[0041] 4B shows a panel piece 10B in which the flat base 40B on the back side is I-shaped. The panel piece 10B is configured using four such I-shaped flat bases 40B as shown. In the panel piece 10B, the flat bases 40B also account for less than half of the panel piece 10B. The hook-and-loop fasteners 50 are attached to each flat base 40B in the horizontal direction, and the flat bases 40B and the hook-and-loop fasteners 50 are approximately the same size.

[0042] When forming a removable wall panel 1 using multiple panel pieces 10A or panel pieces 10B, for example, if the top of panel piece 10A or panel piece 10B is cut off by approximately 1 / 5, as in panel piece 100A in Figure 1B, the shape will be as shown on the right side of each.

[0043] When cut in this manner and used, panel pieces 10A and 10B, which have a very small proportion of flat base 40A and flat base 40B, will lack stability when installed because the proportion of flat base 40A, 40B (and hook-and-loop fastener 50) that comes into direct contact with the existing wall surface W is very small. Therefore, it becomes necessary to reattach the planar bases 40A and 40B to different positions and reattach the hook-and-loop fastener 50.

[0044] However, as in the case of panel piece 10, if the flat base 40 accounts for 70.0 to 90.0% of the panel piece 10, even if the panel piece 10 is cut and used, a sufficient contact area can be ensured with the existing wall surface W, and the panel piece 10 can be used stably without the need for an additional step of attaching the flat base 40. This also contributes to reducing the weight of the panel piece 10.

[0045] Modified examples of the panel piece of the present invention will be described with reference to the drawings. Fig. 5A shows a modified panel piece 10a, and Fig. 5B shows a modified panel piece 10b.

[0046] While the flat base 40 on the rear side of the panel piece 10 was a square plate, the flat base 40a on the rear side of the panel piece 10a is a square plate with rounded corners. The panel piece 10a employing this type of flat base 40a configuration is suitable for cases where, for example, wiring C is bent and routed along an existing wall surface W.

[0047] The flat base 40 on the rear side of the panel piece 10 is made up of four plates, but the flat base 40b on the rear side of the panel piece 10b is made up of only one plate, not multiple plates. The panel pieces of the present invention can also adopt such a configuration.

[0048] As described above, in the panel piece 10 of this embodiment, the flat base 40 is attached to the back side of the panel piece main body 11, and the area of ​​this flat base 40 is smaller than the area of ​​the panel piece main body 11 (the area of ​​the base plate 30). Therefore, it is possible to provide a recess 12 on the back side of the panel piece main body 11 as a space for running the wiring C on the existing wall surface W.

[0049] In this embodiment, a hook-and-loop fastener 50 is used as the detachable member provided on the existing wall surface W side of the flat base 40. However, the detachable member is not limited to a hook-and-loop fastener, and it is also possible to use, for example, a magnet (north or south pole) that can be attached and detached in pair with the existing wall surface W. In addition, in this embodiment, the panel piece main body 11 is formed of the pattern plate 20 and the base plate 30, but it can also be formed of only the base plate 30. In this case, a wall pattern can be applied to the front side of the base plate 30. In addition, in this embodiment, nine pattern plates 20 are used for one panel piece 10, but the number is not limited to this. Also, the shape of the pattern plates 20 is not limited to this embodiment. [Explanation of symbols]
