Description

The present invention relates to a wiring cover that covers wiring installed along a wall surface.

Conventionally, as this type of wiring cover, there has been known one which is formed by combining an inner member and an outer member (see Patent Document 1).
This wiring cover comprises an inner member consisting of a bottom body and left and right inner wall bodies, an outer member consisting of a top body and left and right outer wall bodies, and decorations applied to the surface of the outer member. The left and right inner wall bodies and the left and right outer wall bodies each have an outwardly curved shape and are flexible. This allows the outer member to be detachably attached to the inner member attached to a wall surface or the like, and multiple wirings are housed inside.

JP 2004-180355 A

Conventional wiring covers like this one are easy to manufacture using resin molding technology, but are not suitable for on-site processing. For example, when connecting a cable inside a wiring cover to an exposed outlet or wall switch, rectangular or oval openings must be formed in the inner wall of the inner member and the outer wall of the outer member, but processing the resin in this way is cumbersome.

The objective of the present invention is to provide a wiring cover that can be manufactured easily and at low cost, and that is easy to install, including on-site processing.

The wiring cover of the present invention is a wooden wiring cover that covers wiring that is installed along a wall surface, and has an outer casing material with a U-shaped cross section consisting of a front panel and a pair of side panels that form the storage space for the wiring, and a pair of mounting reinforcements that are installed along the inside of each side panel and are used to fasten to the wall surface with screws. The outer casing material is characterized in that it is formed by bending a plate-shaped MDF material with a V-shaped groove formed at the boundary between the front panel and the pair of side panels into a U-shape.

According to this configuration, the wiring (cables) fixed to the wall surface with a saddle or the like is covered with an outer casing forming material, and the outer casing forming material is fixed to the wall surface with screws via a pair of mounting reinforcements, thereby concealing the wiring on the wall surface.
In this case, by constructing the outer shell forming material from MDF material, the outer shell forming material with a U-shaped cross section can be easily manufactured at low cost even though it is made of wood. In addition, the outer shell forming material made of wood (MDF material) is easy to install, including on-site processing, and has a stable shape that does not warp.

In this case, it is preferable that each mounting reinforcement is made of MDF material with a square cross section.

With this configuration, the MDF mounting reinforcement can be easily attached to the outer shell forming material with adhesive or the like, and the wiring cover itself, including the mounting reinforcement, can be easily manufactured at low cost. In addition, when forming pilot holes for screws or notches in the mounting reinforcement, no cracks or the like occur, and processing can be performed simply and accurately.

It is also preferable that a polyolefin sheet is attached to the surface of the outer shell forming material.

Polyolefin sheets, so-called olefin sheets, are available in a variety of colors for forming decorative laminates.
According to this configuration, a laminate decorative plate is formed to match the color of the wall surface, and the exterior forming material can be manufactured from this decorative plate easily and at low cost. Also, the durability of the exterior forming material can be improved.

It is also preferable that the outer casing material has width and height dimensions that allow the recessed outlet and wall switch to be recessed and installed with the surface of the front panel portion as the installation surface.

With this configuration, the recessed outlet or wall switch can be installed embedded in the surface of the outer casing material as needed. This allows for a neat design around the outlet or wall switch, without compromising the design of the interior.

It is also preferable that the width of the outer shell forming material is between 110 mm and 300 mm.

This configuration results in an installation form (design) that is extremely wide overall and can be mistaken for part of a pillar or beam. This makes it possible to create a wiring cover that is less noticeable and more natural than a typical molding.

Another wiring cover of the present invention is a wooden wiring cover that covers wiring that is attached to the corners of a wall, and has an outer casing material with an "L" shaped cross section consisting of a front panel and a side panel that form the storage space for the wiring, and a mounting reinforcement material that is attached to the inside of the side panel and is used to fasten the wall with screws. The outer casing material is characterized in that it is made by bending a plate-shaped MDF material with a V-shaped groove formed at the boundary between the front panel and the side panel into an "L" shape.

According to this configuration, the wiring (cable) fixed to the corner portion of the wall with a saddle or the like is covered with the outer casing forming material so that it is abutted against the top surface, and the outer casing forming material is fixed to the wall surface with screws via an attachment reinforcement material, so that the wiring on the wall surface is concealed in the corner portion.
In this case, by constructing the outer shell forming material from MDF material, the outer shell forming material with an "L"-shaped cross section can be easily formed at low cost even though it is made of wood. In addition, the outer shell forming material made of wood (MDF material) is easy to install, including on-site processing, and has a stable shape that does not warp.

In this case, it is preferable that the mounting reinforcement be made of MDF material with a square cross section.

With this configuration, the MDF mounting reinforcement can be easily attached to the outer shell forming material with adhesive or the like, and the wiring cover itself, including the mounting reinforcement, can be easily manufactured at low cost. In addition, when forming pilot holes for screws or notches in the mounting reinforcement, no cracks or the like occur, and processing can be performed simply and accurately.

It is also preferable that a polyolefin sheet is attached to the surface of the outer shell forming material.

This configuration allows a laminate decorative panel to be formed to match the color of the wall surface, and the exterior forming material can be manufactured from this decorative panel easily and at low cost. It also improves the durability of the exterior forming material.

Below, a wiring cover according to one embodiment of the present invention will be described with reference to the attached drawings. This wiring cover is a protective cover for wiring exposed on a wall surface resulting from renovation work, etc., but is made much wider than a typical one (molding) so that recessed outlets, wall switches, etc. can be installed on the cover itself. Furthermore, this wide wiring cover with outlets, etc. installed on it is less noticeable as a result, improving the design of the room. In this embodiment, five different types of wiring covers are prepared depending on whether they accommodate a large number of wiring cables (two-wire) or a small number (single-wire), whether an existing switch box can be used for the newly installed outlet or wall switch, etc.

[Embodiment]
Fig. 1 shows an A-type cover 10A having a U-shaped cross section among the five types of wiring covers 10, and Fig. 2 shows a B-type cover 10B having an L-shaped cross section. Fig. 1(a) shows an A-first cover 10Aa of the A-type cover 10A, Fig. 1(b) shows an A-second cover 10Ab, Fig. 1(c) shows an A-third cover 10Ac, and Fig. 1(d) shows an A-fourth cover 10Ad.

The B type cover 10B only functions as a protective cover for the wiring cable CA (wiring). On the other hand, the A type cover 10A not only functions as a protective cover for the wiring cable CA, but also functions as an installation base for wiring devices such as the outlet PS and wall switch WS connected to the wiring cable CA. Both the A type cover 10A and the B type cover 10B are fixed directly to the wall surface WW, and form a storage space for the wiring cable CA between them and the wall surface WW. The A type cover 10A has a U-shaped cross section, and the B type cover 10B has an L-shaped cross section, but both have a standard length of 2430 mm.

The A-first cover 10Aa has a width (W) x height (H) dimension of 115 mm x 24 mm, and is used primarily when a series of wiring devices (a series of wiring cables CA) such as an outlet PS and a wall switch WS are to be installed, and the existing switch box SB (back box) of the outlet PS or wall switch WS can be used. In other words, this A-first cover 10Aa is used when a new outlet PS or wall switch WS is to be installed via the wiring cover 10 in the same position as the existing recessed outlet PS or wall switch WS (see FIG. 7(b)).

The A-second cover 10Ab has a width (W) x height (H) dimension of 115 mm x 34 mm, and is used primarily when a series of wiring devices (a series of wiring cables CA) such as an outlet PS and a wall switch WS is to be installed, and the existing switch box SB for the outlet PS or wall switch WS cannot be used. In other words, this A-second cover 10Ab is used when a new outlet PS or wall switch WS is to be installed via the wiring cover 10 in a position different from the existing recessed outlet PS or existing wall switch WS, or when an additional outlet PS or wall switch WS is to be installed (see FIG. 7(b)).

The A third cover 10Ac has a width (W) x height (H) dimension of 200 mm x 24 mm, and is used primarily when installing two-wire devices such as an intercom IP or a PS outlet + TV terminal, and when an existing switch box SB can be used for these PS outlets, etc. (see Figure 7 (b)).

A fourth cover 10Ad has a width (W) x height (H) dimension of 200 mm x 34 mm, and is used primarily when installing two-wire devices such as an intercom IP or a PS outlet + TV terminal, and when an existing switch box SB can be used for these PS outlets, etc. (see Figure 7 (b)).

The B-type cover 10B has a width (W) x height (H) dimension of 39 mm x 24 mm, and is used primarily as a protective cover for the wiring cable CA in the corner area where the wall surface WW and the ceiling surface SW meet (see Figure 7 (b)).

[A type cover]
Here, the structure of the A type cover 10A will be described with reference to Fig. 1. As described above, the A first cover 10Aa, the A second cover 10Ab, the A third cover 10Ac, and the A fourth cover 10Ad have the same basic structure, although they are different in size. Therefore, the structure of the A type cover 10A will be described below using the A first cover 10Aa as an example (see Fig. 1(a)).

As shown in FIG. 1(a), the A-type cover 10A (A-first cover 10Aa) has an outer shell forming material 20A with a U-shaped cross section consisting of a front plate portion 21 and a pair of side plate portions 22, and a pair of mounting reinforcement members 30A attached to the inside of each side plate portion 22. Both the outer shell forming material 20A and the mounting reinforcement members 30A are made of MDF (median density fiberboard), which is a wood material. Instead of MDF, the outer shell forming material 20A and the mounting reinforcement members 30A may be made of wood materials such as hardboard.

The front plate 21 and side plate 22 that make up the outer casing 20A form a storage space for the wiring cable CA between them and the wall surface WW, and are formed by bending a 4 mm thick plate-shaped MDF material with a V-shaped groove 24 formed at the boundary between the front plate 21 and the pair of side plate 22 into a U-shape (see Figures 3(c) and (d)). An olefin sheet 35 (a polyolefin sheet) is attached to the surface of the U-shaped outer casing 20A. Details will be described later, but the olefin sheet 35 is attached to the surface of the outer casing 20A at the early stage of manufacturing the A-type cover 10A.

In this case, the olefin sheet 35 is commercially available in many colors, and in this embodiment, a sheet of the same color is selected to match the color of the wall surface WW to be installed. If the wall surface WW is covered with cloth, the same cloth is applied on top of the olefin sheet 35.

Each mounting reinforcement 30A is attached to the side panel 22 at the inner corner between the front panel 21 and the pair of side panel 22 so that the end face is flush with the end face of the side panel 22. Each mounting reinforcement 30A is used to screw the A-type cover 10A to the wall surface WW, and has a width of 15 mm for screwing (the embodiment (A-type first cover 10Aa) is 20 mm long x 15 mm wide). Details will be described later, but in actual screwing, a clearance hole 51 is formed through the front panel 21 at the middle position in the width direction of the mounting reinforcement 30A (see FIG. 5(c)), and a screw 57 is screwed into the wall surface WW through this clearance hole 51 to screw it in (see FIG. 6(f)).

Such an A-type cover 10A not only houses the wiring cable CA, but also functions as an installation base for wiring devices such as the outlet PS and wall switch WS. As a result, it also mimics part of a pillar or beam. For this reason, the A-type cover 10A in the embodiment has a width of 115 mm and 200 mm, but considering wiring devices with one to three rows, it is preferable that the width be 110 mm to 300 mm.

[B type cover]
Next, the structure of the B-type cover 10B will be described with reference to Fig. 2. As shown in the figure, the B-type cover 10B has an outer shell forming member 20B having an "L"-shaped cross section, which is composed of a front plate portion 21 and a side plate portion 22, and an attachment reinforcement member 30B provided along the inside of the side plate portion 22. In this case, the outer shell forming member 20B and the attachment reinforcement member 30B are also formed of MDF (median density fiberboard), which is a wood material. In this case, the outer shell forming member 20B and the attachment reinforcement member 30B may also be formed of a wood material such as hardboard instead of MDF.

The front plate 21 and side plate 22 that make up the outer casing 20B mainly form a storage space for the wiring cable CA between the wall surface WW and the ceiling surface SW, and are formed by bending a 4 mm thick plate-shaped MDF material into an "L" shape, with a V-groove 24 formed at the boundary between the front plate 21 and the side plate 22. An olefin sheet 35 is attached to the surface of the "L" shaped outer casing 20B. In this case too, the olefin sheet 35 is attached to the surface of the outer casing 20B in the early stages of manufacturing the B-type cover 10B.

The mounting reinforcement 30B is attached to the side panel 22 at the inner corner between the front panel 21 and the side panel 22 so that the end face is flush with the end face of the side panel 22. The mounting reinforcement 30B is used to screw the B-type cover 10B to the wall surface WW, and has a width of 15 mm for screwing (the embodiment has a length x width of 20 mm x 15 mm).

[Production method]
Next, a method for manufacturing the wiring cover 10 will be described with reference to FIG. 3, taking the A-type cover 10A as an example.
The manufacturing method for the wiring cover 10 includes a lamination process (FIG. 3(a)) in which an olefin sheet 35 is attached to the surface of the base material, a cut-to-slit process (FIG. 3(b)) in which this laminated decorative panel is cut into small pieces to fit various wiring covers 10, a V-groove cutting process (FIG. 3(c)) in which a V-groove 24 is formed on the back surface of the cut-to-slit decorative panel, and a bending and bonding process (FIG. 3(d)) in which the decorative panel is folded at the V-groove 24 and an attachment reinforcement material 30A is bonded.

In the lamination process shown in FIG. 3(a), adhesive is applied to a 1220 mm x 2430 mm x 4 mm MDF substrate 41 that will become the outer shell forming material 20A (20B), and then an olefin sheet 35 is attached with a press roller. In other words, a polyolefin laminate decorative panel 40 is formed. The olefin sheet 35 is selected to have a color that matches the color of the wall surface WW on which it is to be installed.

In the small cutting process of FIG. 3(b), the laminate decorative board 40 is cut into small pieces according to the size of the wiring cover 10. In this case, for the A-type first cover 10Aa, it is cut into small pieces with a width of 115 mm + 24 mm + 24 mm = 163 mm. Similarly, for the A-type second cover 10Ab, it is cut into small pieces with a width of 183 mm, for the A-type third cover 10Ac, it is cut into small pieces with a width of 263 mm, for the A-type fourth cover 10Ad, it is cut into small pieces with a width of 283 mm, and for the B-type cover 10B, it is cut into small pieces with a width of 65 mm.

On the other hand, for the small cuts for the mounting reinforcement 30A (30B), a 1220 mm x 2430 mm x 15 mm MDF base material 45 is used, which is cut into small pieces of 20 mm width (for A-type first cover 10Aa, A-type third cover 10Ac, and B-type cover 10B) or 30 mm width (for A-type second cover 10Ab and A-type fourth cover 10Ad).

In the V-groove cutting process shown in FIG. 3(c), a V-groove 24 is formed on the back surface of the cut decorative panel 40a that has been cut into small pieces, with the olefin sheet 35 remaining. That is, a groove is formed on the boundary between the part of the cut decorative panel 40a that will become the front panel portion 21 and the part that will become the pair of side panel portions 22. Needless to say, the V-groove 24 is formed in two places, on the left and right, in the A-type cover 10A, and the V-groove 24 is formed in one place in the B-type cover 10B. The groove angle of the V-groove 24 is 90°.

In the bending and gluing process shown in FIG. 3(d), adhesive is applied to the necessary locations on the widthwise end of the cut decorative panel 40a, including the V-groove 24, and the widthwise end that will become the side panel portion 22 is bent at an angle of 90°. At the same time, small cut attachment reinforcement material 30A is introduced into this portion and thickly fastened with a roller press. Then, the process moves to the packaging process.

In the above manufacturing process, it is preferable to use a lamination line in the lamination process, a running saw in the small cut process, and a V-cut line in the V-groove cutting process and bending/bonding process.

[Installation procedure]
Next, a basic procedure for installing the wiring cover 10 will be described with reference to the installation example of FIG. 4 and its explanatory views of FIGS.
The basic procedure for installing the wiring cover 10 is as follows:
Step 1: Measure the dimensions of the path along which the wiring cover 10 is to be installed.
Step 2: Cut the wire cover 10 based on the measured dimensions.
Step 3: Drill holes and cutouts in the wiring cover 10 .
Step 4: The wiring cover 10 is processed to accommodate the wiring device.
Step 5: Attach the wiring cover 10 to the wall surface WW.
Step 6: Install wiring devices, etc. onto the wiring cover 10.
Step 7: A functional test is carried out and the screws of the wiring cover 10 are hidden.
It becomes something.

In the construction example of Figure 4, Figure 4(a) shows the state of the wall surface WW before the wiring cover 10 is installed. Meanwhile, Figures 4(b) and (c) are a front view and a cross-sectional view of the wall surface WW with the wiring cover 10 installed. In this construction example, a wall switch WS and a socket PS are newly installed on the inner wall surface (wall surface WW) where the concrete beam B and the wall are connected, and the source side of the wiring cable CA is introduced (wired) so that it runs along the ceiling surface SW. The wall surface WW is set back from the beam B, and the wiring cable CA and wiring cover 10 are installed along it from the ceiling surface SW.

A type cover 10A is used for the vertical wiring cover 10 from the floor surface FW to the ceiling surface SW, and a type B cover 10B is used for the horizontal wiring cover 10 installed along the ceiling surface SW. The wall switch WS is installed at a height of 1200 mm from the floor surface SW, and the outlet PS is installed at a height of 200 mm from the floor surface SW.

In step 1, the path of the same wiring cover 10 is measured in straight line segments. Next, based on the measurement results, a fixed-length wiring cover 10 is marked (line drawn). In the construction example, a convex or similar tool is used to measure the vertical dimensions from the floor surface FW to the underside of the beam B, the projection dimension of the beam B from the wall surface WW, and the vertical dimensions from the underside of the beam B to the ceiling surface SW (see Figure 5(a)), and these dimensions are then measured onto the fixed-length wiring cover 10.

In step 2, the wiring covers 10 are cut along the marked lines (see FIG. 5(b)). It is preferable to use an electric circular saw for cutting. After cutting, it is also preferable to place each wiring cover 10 in its installation position to check that the cut dimensions are correct.

In step 3, the clearance holes 51 for screw fixing are drilled in the mounting reinforcement 30A (30B) of the wiring cover 10 (see FIG. 5(c)). Also, cutouts 52 are formed in the parts where the wiring cover 10 is joined at right angles. The specifications for the wiring cover 10 (fixed to the wall) are four places at the four corners for a length of less than 1.5 m for the A-type cover 10A, and six places at the four corners and in the middle for a length of 1.5 m or more, and two places at both ends for a length of less than 1.5 m for the B-type cover 10B, and three places at both ends and in the middle for a length of 1.5 m or more. Therefore, the clearance holes 51 for screw fixing are formed at the mounting reinforcement positions in six places for the A-type cover 10A installed on the wall surface, four places each for the A-type cover 10A installed on the underside and front of the beam B, and two places for the B-type cover 10B installed under the ceiling (see FIG. 4).

On the other hand, as shown in FIG. 5(d), at the connection between the A-type cover 10A on the front side of the beam B and the B-type cover 10B, a rectangular cutout 52 that communicates with the B-type cover 10B is formed on the side of the upper end of the A-type cover 10A. The cutout 52 is formed by cutting the side plate 22 and the mounting reinforcement 30A of the A-type cover 10A according to the cross section of the housing part of the B-type cover 10B. At the connection between the A-type cover 10A installed on the wall surface WW and the A-type cover 10A installed on the underside of the beam B, the front plate 21 is cut into a square shape at the end of the A-type cover 10A installed on the underside. It is also preferable to cut out a notch when the wiring cover 10 intersects with a lintel or baseboard.

In step 4, an installation opening 54 for wiring devices such as a power outlet PS and a wall switch WS is formed in the wiring cover 10 (A-type cover 10A) (see FIG. 6(e)). The installation opening 54 is marked out in an oval shape and cut out with a hand saw or an oval-shaped electric hole saw.

In step 5, the wiring cover 10 is screwed to the wall surface WW while housing the wiring cable CA. As described above, the wiring cover 10 is screwed to the wall surface WW in multiple locations, mainly at the corners (see FIG. 6(f)). The multiple wiring covers 10 are installed in order, starting from the base of the wiring cable CA. Note that the bottom end surface of the A-type cover 10A installed on the front of the beam B is open. In this embodiment, plate-shaped end covers 55 are prepared to correspond to various wiring covers 10, and the corresponding end cover 55 is adhered to the bottom end surface of this A-type cover 10A (see FIG. 6(f)).

The fixing screws 57 have a flat head and are screwed in so that the surface of the head is flush with the surface of the wiring cover 10. If the wall surface WW to be screwed in is a concrete structure, a plug should be used; if it is plasterboard, a board anchor should be used; if it is wood, a wood screw should be used.

In step 6, the outlet PS and wall switch WS are installed on the wiring cover 10. When installing the outlet PS, the switch box SB of the outlet PS is fixed in advance to a predetermined position on the wall surface WW, and after installation on the wiring cover 10, the outlet body PSa, plastic frame PSb, plate PSc, etc. are attached (see Figure 6 (g)). The same is true for the wall switch WS. Note that when installing a new outlet PS or wall switch WS via the wiring cover 10 in the same position as an existing recessed outlet PS or an existing wall switch WS, the switch box SB will be located deep relative to the surface of the wiring cover 10, so a joint frame (not shown) is provided in the resulting gap (approximately 20 mm).

In step 7, a functional test is performed and the screws in the wiring cover 10 are hidden. To hide the screws in the wiring cover 10, a circular sticker 58 of the same color as the surface of the wiring cover 10 is attached to the surface of the flat head screw of the screw 57 (see Figure 6 (h)).

[Example of construction]
Next, an example of installation of the wiring cover 10 will be described with reference to FIGS.
Fig. 7 shows an example of a kitchen/intercom installation. As shown in Fig. 7(a), an intercom IP is installed on the wall WW of the existing kitchen (before installation), and a built-in wall switch WS is installed near the intercom IP. The intercom line IPC from the built-in box EB is wired in the form of a mall wiring, and is first wired to the ceiling surface SW before reaching the intercom IP.

In this example of renovation, a new wiring cover 10 is installed along the mall wiring, and a new wall switch WS is installed while retaining the switch box SB of the existing wall switch WS. Also, a new intercom IP with a monitor is installed in place of the existing intercom IP. Furthermore, an outlet PS for large equipment is added to the wall surface WW above the opening (sliding door).

As shown in Figure 7(b), in place of the intercom line IPC mall wiring from the existing recessed box EB to the ceiling surface SW, an A-type first cover 10Aa (115 mm x 24 mm) is installed in this area while making use of the existing recessed box EB. Also, for the area around the intercom IP, an A-type third cover 10Ac (200 mm x 24 mm) is installed from the ceiling surface SW to the floor surface FW, taking into consideration the new installation of an intercom IP with a monitor and a wall switch WS. A B-type cover 10B (39 mm x 24 mm) is installed between the A-type first cover 10Aa and the A-type third cover 10Ac, aligned with the ceiling surface SW.

A new intercom IP with a monitor and a new wall switch WS are installed on the surface of the A-third cover 10Ac. The new wall switch WS is installed in the same position as the existing wall switch WS, and the switch box SB of the existing wall switch WS is converted into the new wall switch WS. In this case, the above-mentioned extension frame is attached to the switch box SB. When adding an outlet PS for a large device, it is a completely new installation, so the A-second cover 10Ab (115 mm x 34 mm) is installed. Note that when adding an outlet PS below the wall switch WS, the A-fourth cover 10Ad (200 mm x 34 mm) is installed instead of the A-third cover 10Ac.

The example in Figure 8 is an example of adding a switch and outlet to a room. As shown in Figure 8 (a), this room has one outlet PS installed near the window. In this case, a new outlet PS is installed in the same position as the existing outlet PS, and a wall switch WS and an outlet PS are added near the sliding door.

As shown in FIG. 8(b), in order to provide a new outlet PS at the position of the existing outlet PS near the window, A-first cover 10Aa (115 mm x 24 mm) is installed from the ceiling surface SW to the floor surface FW of this part. In this case, too, a new wall switch WS is installed on A-first cover 10Aa while repurposing the switch box SB of the existing wall switch WS. Also, in order to add a wall switch WS and an outlet PS near the sliding door, A-second cover 10Ab (115 mm x 34 mm) is installed from the ceiling surface SW to the floor surface FW of this part.

In this A-type second cover 10Ab, a power outlet PS is installed 200 mm from the floor surface FW, and a wall switch WS is installed 1200 mm from the floor surface FW. Then, a B-type cover 10B (39 mm x 24 mm) is installed between the A-type first cover 10Aa and the A-type second cover 10Ab so as to fit along the ceiling surface SW.

As described above, according to the A-type cover 10A of this embodiment, the outer shell forming material 20A and the pair of mounting reinforcement materials 30A are made of MDF material, so they can be easily manufactured at low cost despite being made of wood. In addition, the outer shell forming material 20A and the mounting reinforcement materials 30A made of wood (MDF material) are easy to install, including on-site processing, and have a stable shape that does not become distorted. Moreover, not only can embedded outlets PS and wall switches WS be installed, but the design is wide and unobtrusive, and does not impair the interior design.
