Embodiments embodying the disclosed technology will be described in detail with reference to the accompanying drawings. Figure 1 shows a bathroom vanity unit 1 equipped with a front panel 10 according to one embodiment of the present invention.

The bathroom vanity 1 has a vanity unit main body 5, a mirror cabinet 6, a faucet device 7, and a front panel 10. The vanity unit main body 5 is an example of an "interior box." In the following description, the left-right direction in Figure 1 is referred to as the width direction X, the front-to-rear direction in Figure 1 as the depth direction Y, and the up-to-down direction in Figure 1 as the height direction Z. In Figure 1, the side closer to a user standing in front of the vanity unit 1 is referred to as the "front side," and the side farther from the user as the "rear side."

In the washbasin main body 5, a counter board 3 is installed on the upper surface of the lower cabinet 2. A washbasin 4 is integrally formed with the counter board 3. The counter board 3 may be provided with multiple washbasins 4. The washbasin 4 may also be provided separately from the counter board 3.

The mirror cabinet 6 is a cabinet with multiple doors. A mirror is attached to each door. The mirror cabinet 6 may have a shelf formed on at least a portion of it. The faucet device 7 is attached to the bottom of the mirror cabinet 6. The faucet device 7 incorporates a faucet 8 and a handle 9. The faucet 8 and handle 9 are installed above the washbasin 4.

The front panel 10 is positioned between the washbasin main body 5 and the mirror cabinet 6. The front panel 10 is positioned on the rear side of the washbasin main body 5.

The bathroom vanity 1 is installed in the installation space S20. In this embodiment, the installation space S20 is a space partitioned by a pair of side walls 72, 73 and a rear wall 71. The rear wall 71 is a wall located on the rear side between the pair of side walls 72, 73. The bathroom vanity 1 is housed between the side wall 72 and the side wall 73. Only one of the side walls 72, 73 may be provided.

As shown in Figure 2, the front panel 10, which is disposed between the surface 72 and the wall surface 73, has a base 60 and a panel member 11. The panel member 11 is an example of a "main panel." The base 60 is fixed to the rear wall surface 71. The base 60 forms a piping space S2. The piping space S2 is a space for placing a water supply pipe 80 that connects to the faucet 8 (see Figure 1). The panel member 11 is removably attached to the base 60 from the front side. The panel member 11 conceals the piping space S2 so that it cannot be seen by the user.

A gap S11 is formed between the end 11a of the panel member 11 on the left side in the figure and the side wall surface 72. A filler 20 is attached to the end 11a of the panel member 11 on the left side in the figure. The filler 20 on the left side in the figure conceals the gap S11. A gap S12 is formed between the end 11a of the panel member 11 on the right side in the figure and the side wall surface 73. A filler 20 is attached to the end 11a of the panel member 11 on the right side in the figure. The filler 20 on the right side in the figure conceals the gap S12. The width dimension of the front panel 10 is slightly smaller than the distance between the side wall surfaces 72 and 73. The difference is adjusted by the filler 20.

As shown in Figures 3 and 4, the front panel 10 has a panel member 11, a filler 20, a parting member 30, a spring member 40, a foam sealing material 50, and a base 60. A parting member 30 is fixed to each of both end portions 11a, 11a of the panel member 11 in the width direction X. A spring member 40 is fixed to the parting member 30. The filler 20 is sandwiched and held between the parting member 30 and the spring member 40. As shown in Figure 4, foam sealing material 50 is disposed on each of the upper edge 11e and lower edge 11f of the panel member 11.

As shown in Figure 3, the panel member 11 has a rectangular shape. As shown in Figure 2, the panel member 11 includes a base plate 12 and a decorative plate 13. The decorative plate 13 is a plate decorated on the user-facing surface. As shown in Figure 3, tiles are arranged side by side on the decorative plate 13 of this embodiment. The base plate 12 is cut to fit the size of the decorative plate 13. The decorative plate 13 is adhered to one surface of the base plate 12.

As shown in Figure 4, protruding members 51 are fixed at multiple locations on the other surface of the base plate 12. The protruding members 51 are arranged to protrude from the base plate 12. The base 60 is formed by combining multiple frames. A catch member 61 is attached to the base 60. The catch member 61 is a member into which the protruding members 51 are detachably fitted. By fitting the protruding members 51 into the catch members 61 from the front side, the installer can attach the panel member 11 to the base 60 without using tools.

As shown in Figure 4, the dimension of the parting member 30 in the height direction Z is set to the length from the upper edge 11e to the lower edge 11f of the panel member 11. The parting member 30 is fixed to the panel member 11 so as to cover the end face 11c (see Figure 5) located in the width direction X of the panel member 11.

As shown in Figure 5, the parting member 30 has an end surface portion 31, a back surface portion 32, and a rear portion 33. The end surface portion 31, the back surface portion 32, and the rear portion 33 are connected via a connection position P1. The parting member 30 has a T-shape when viewed from above. Figure 5 is a view of the end portion 11a of the front panel 10 from above, and the foam sealant 50 is omitted.

As shown in Figure 6, the end surface portion 31 is a portion that is placed on the end surface 11c of the panel member 11. The length L1 from the connection position P1 to the front end 31a of the end surface portion 31 is set to a value greater than the thickness M1 of the base plate 12. This is so that the end surface portion 31 covers and conceals the step between the base plate 12 and the decorative plate 13, forming an attachment surface for the filler 20. The length L1 is set slightly smaller than the thickness M2 from the front surface 11d to the back surface 11b of the panel member 11. This is so that an attractive seal can be created between the front end 31a of the parting member 30 and the front surface 11d of the panel member 11.

As shown in Figures 5 and 6, the back surface portion 32 is a portion that is disposed on the back surface 11b of the panel member 11. The back surface portion 32 is connected to the rear end portion of the end surface portion 31 via a connection position P1. The back surface portion 32 is disposed perpendicular to the end surface portion 31. The back surface portion 32 is fixed to the back surface 11b of the panel member 11 using fixing screws 39.

In this embodiment, as shown in Figure 4, the lower end portion of the back surface portion 32 is also cut out, similar to the upper end portion of the back surface portion 32.

As shown in FIG. 6 , the rear portion 33 extends from the connection position P1 toward the rear of the panel member 11. The rear portion 33 is located on the opposite side of the connection position P1 from the end surface portion 31. The rear portion 33 is located perpendicular to the back surface portion 32. The length L2 from the connection position P1 to the rear end 33a of the rear portion 33 is different from the length L1 from the connection position P1 to the front end 31a of the end surface portion 31. This is because the parting member 30 can be inverted and fixed to the panel member 11 depending on the thickness M2, material, design, etc. of the panel member 11. When the parting member 30 is used in an inverted state, the rear portion 33 functions as the end surface portion, and the end surface portion 31 functions as the rear portion. In this embodiment, the length L2 is set to be approximately the same as the thickness M1 of the base plate 12. The length L2 is set to be shorter than the length L1.

As shown in FIG. 7 , the parting member 30 is provided with a first spring member mounting portion 34 and a second spring member mounting portion 35. In this embodiment, the first spring member mounting portion 34 and the second spring member mounting portion 35 are formed as through holes into which mounting screws 49 can be inserted. The spring member 40 is mounted to either the first spring member mounting portion 34 or the second spring member mounting portion 35 using the mounting screws 49. The first spring member mounting portion 34 and the second spring member mounting portion 35 are examples of "mounting shapes."

The parting member 30 has a first spring member mounting portion 34 and a second spring member mounting portion 35 provided on a surface 38 located opposite the end surface 11c of the panel member 11. This is so that the spring member 40 can be fixed to the parting member 30 after the parting member 30 is fixed to the panel member 11. The first spring member mounting portion 34 is provided on the rear portion 33. The second spring member mounting portion 35 is provided on the end surface portion 31. This is so that the mounting position of the spring member 40 can be changed in the depth direction Y depending on the shape of the filler 20. The first spring member mounting portion 34 and the second spring member mounting portion 35 are provided in the center of the parting member 30 in the height direction Z. This is so that only one spring member 40 is attached to the parting member 30, making it easier to attach the filler 20 from the front side.

As shown in FIG. 6 , the spring member 40 is a leaf spring having a fixed portion 41 and a flexible portion 42. The fixed portion 41 is a flat portion fixed to the parting member 30 using an attachment screw 49. The flexible portion 42 is a portion that deforms by bending, with the fixed portion 41 as the base point. The flexible portion 42 is bent from the portion connected to the fixed portion 41 toward the opposite side of the parting member 30 and is positioned away from the parting member 30. The end portion 43 of the flexible member 42, located on the surface 11d side of the panel member 11, is bent toward the parting member 30. The distance by which the flexible member 42 separates from the parting member 30 is narrowed at the end portion 43. When not holding the filler 20, the end portion 43 of the spring member 40 is positioned with a distance W1 between it and the end surface 31 of the parting member 30. When not holding the filler 20, the spring member 40 forms a gap S10 between the end portion 43 and the end surface 31. The gap S10 is open to the surface 11d side of the panel member 11.

The filler 20 has an insertion portion 21 and a front surface portion 22. The insertion portion 21 and front surface portion 22 are arranged in an L-shape. The insertion portion 21 is inserted between the parting member 30 and the spring member 40 via the gap S10 between the spring member 40 and the end surface portion 31. The distance W1 when the filler 20 is not being held is set to a value smaller than the thickness W2 of the insertion portion 21. This is because the spring force of the flexible portion 42 holds the insertion portion 21 between the parting member 30 and the spring member 40.

The front surface 22 is a portion that is positioned alongside the surface 11d of the panel member 11. The surface 22a located on the front side of the front surface 22 is flat. The surface 22a that is exposed to the user's eyes may be decorated, for example, by attaching tiles similar to those used on the decorative plate 13. The surface 22b located on the rear side of the front surface 22 is formed with fine corrugations. The corrugated grooves are formed along the height direction Z. This allows workers at the installation site of the front panel 10 to cut the front surface 22 along the grooves using only a cutter, thereby adjusting the width of the filler 20.

The procedure for installing the front panel 10 described above will now be explained. When shipped from the factory, the front panel 10 has a parting member 30 secured to both ends 11a, 11a of the panel member 11 in the width direction X with fixing screws 39. The parting member 30 is secured to the panel member 11 with its end surface 31 in contact with the side surface 11c of the panel member 11. The front end 31a of the end surface 31 of the parting member 30 is aligned with the surface 11d of the panel member 11. The gap between the parting member 30 and the panel member 11 is sealed. Foam sealing material 50 is attached to the upper edge 11e and lower edge 11f of the panel member 11. The front panel 10 is packaged and transported to its installation destination without the spring member 40 attached. This is to prevent the spring member 40 from being damaged or falling off during transport. The panel member 11 is packaged together with the base 10 and transported to its installation destination.

At the installation site, the worker unpacks the product and removes the panel member 11 and base 10. The worker secures the base 60 to the rear wall surface 71 above the washbasin unit 5 installed in the installation space S20 shown in Figures 1 and 2, for example. The worker secures the mirror cabinet 6 above the base 60. The worker attaches the faucet device 7 to the bottom of the mirror cabinet 6. The worker uses the piping space S2 of the base 60 to connect the water supply pipe 80 (see Figure 2) to the faucet device 7.

The worker uses the mounting screw 49 to attach the spring member 40 to the first spring member mounting portion 34 of the parting member 30. The worker fits the protruding member 51 of the panel member 11 into the catch member 61 of the base 60. The panel member 11 is attached to the base 60 from the front side so as to cover the water supply pipe 80. The gap between the upper edge 11e of the panel member 11 and the mirror cabinet 6 is sealed with the upper foam sealing material 50. The gap between the lower edge 11f of the panel member 11 and the counter board 3 of the washbasin main body 5 is sealed with the lower foam sealing material 50. The lower foam sealing material 50 prevents the counter board 3 from being damaged by the panel member 11.

The worker measures the dimension of the gap S12 between the end face 11c (on the right side in the figure) of the panel member 11 attached to the base 60 and the side wall surface 73. The worker cuts the front surface 22 of the filler 20 with a cutter to fit the measured dimension. The worker can cut the front surface 22 straight along the groove formed in the front surface 22 without using a ruler or the like. The width dimension of the filler 20 is adjusted to a value appropriate for the gap S12.

When the panel member 11 is attached to the base 60, the gap S10 formed between the parting member 30 and the spring member 40 is open to the front surface 11d of the panel member 11. As shown in Figure 6, the worker inserts the insertion portion 21 of the filler 20 into the gap S10 between the parting member 30 and the spring member 40 from the front surface 11d side of the panel member 11. The insertion portion 21 is inserted into the gap S10 while deforming the flexible portion 42 of the spring member 40 in a direction away from the end surface portion 31.

As shown in Figure 5, the worker inserts the insertion portion 21 into the gap S10 until the front surface 22 of the filler 20 is aligned with the surface 11a of the panel member 11. The spring force of the flexible portion 42 clamps the insertion portion 21 between the end surface 31 and the end 43 of the spring member 40. The filler 20, whose width has been adjusted to fit the gap S12, is fitted tightly between the end surface 11c of the panel member 11 and the side wall surface 73, concealing the gap S12.

The worker similarly adjusts the width dimension of the filler 20 placed on the left side of the panel member 11 in the figure, concealing the gap S11 with the filler 20.

The width of the front panel 10 is adjusted by fillers 20 placed at both ends 11a, 11a of the panel member 11 in the width direction X. The front panel 10 is installed between the side wall surfaces 72 and 73 so as not to move in the width direction X.

As described above, in the front panel 10 of this embodiment, the spring member 40 is fixed to the parting member 30, which is fixed to the end of the panel member 11. The width of the front panel 10 can be adjusted by sandwiching the filler 20, which is a width-adjusting member, between the parting member 30 and the spring member 40. Therefore, with the front panel 10 of this embodiment, it is possible to adjust the width while hiding the piping 80.

The front panel 10 of this embodiment allows the spring member 40 to be positioned closer to the surface 11d of the panel member 11 than when the spring member 40 is fixed to the base 60. With the front panel 10 of this embodiment, the step formed between the surface 11d of the panel member 11 and the front portion 22 of the filler 20 is smaller than when the spring member 40 is fixed to the base 60. As shown in FIG. 5, the front portion 22 of the filler 20 can be positioned alongside the surface 11d of the panel member 11, making it possible to adjust the width of the front panel 10 for an attractive appearance, as shown in FIG. 2.

As shown in FIG. 6, in the front panel 10 of this embodiment, the insertion portion 21 of the filler 20 can be inserted from the front side into the gap S10 formed between the parting member 30 and the spring member 40. Without using tools, the worker can simply push the filler 20 into the gap S12 from the front side, thereby placing the filler 12 between the end portion 11a of the panel member 11 and the side wall surface 73. This allows the worker to easily adjust the width of the front panel 10.

As shown in FIG. 3, the front panel 10 of this embodiment uses a panel member 11 in which a decorative plate 13 with tiles arranged on it is adhered to a base plate 12. The width dimension of the panel member 11 is adjusted to a position that makes it easy to cut the decorative plate 13, such as the tile joints. Therefore, as shown in FIG. 2, the base 60 is positioned inside the end face 11c of the panel member 11. The front panel 10 of this embodiment is configured so that the parting member 30 is fixed along the end face 11c of the panel member 11 and the spring member 40 is fixed to the parting member 30. Therefore, even if the base 60 is positioned inside the end face 11c of the panel member 11, the front panel 10 of this embodiment can fix the spring member 40 in a position suitable for attaching the filler 20.

As shown in FIG. 5, in the front panel 10 of this embodiment, a first spring member mounting portion 34 is provided on the rear portion 33 of the parting member 30, and the spring member 40 is fixed to the first spring member mounting portion 34. The rear portion 34 is located rearward of the back surface 11b of the panel member 11. Therefore, with the front panel 10 of this embodiment, the filler 20 can be held in a position equivalent to when the spring member 40 is fixed to the base 60.

In the front panel 10 of this embodiment, as shown in FIG. 6, a second spring member attachment portion 35 is also provided on the end surface portion 31 of the parting member 30. The worker can also attach a spring member 40 to the end surface portion 31. The length L2 of the rear portion 33 is set shorter than the length L1 of the end surface portion 31. This type of parting member 30 can also be used when the panel member 11 is replaced with a panel member 11x, as shown in FIG. 8, for example. The front panel 11x is constructed by adhering a glass plate 13x to a base plate 12 instead of the decorative panel 13 decorated with tiles.

Figure 9 shows the end structure of the front panel 10 using a glass plate 13x. Figure 9 corresponds to Figure 5, and omits the foam sealant 50 and the mounting bracket 150 described below. The thickness of the glass plate 13x shown in Figure 9 is thinner than the thickness of the decorative plate 13 with tiles arranged as shown in Figures 5 and 6. The thickness M2x of the panel member 11x is thinner than the thickness M2 (Figure 6) of the panel member 11x by the difference in thickness between the glass plate 13x and the decorative plate 13. The parting member 30 is fixed to the panel member 11x upside down so that its rear portion 33, whose length L2 is approximately the same as the thickness M1 of the base plate 12, is positioned on the end surface 11cx of the panel member 11x. In the parting member 30 fixed to the panel member 11x, the end surface portion 31 is positioned rearward of the back surface 11 of the panel member 11x. The spring member 40 is attached to the second spring member mounting portion 35 provided on the end surface 31. Even when the parting member 30 is attached to the panel member 11x in an inverted position, the spring member 40 is attached in the same position as when it is attached to the base 60.

When the parting member 30 is fixed to the panel member 11x, the rear end 33a of the rear portion 33 is aligned with the surface located on the front side of the base plate 12. The insert portion 21 of the filler 20 is inserted between the parting member 30 and the spring member 40 so that the front portion 22 is aligned with the rear end 33a of the rear portion 33. Because the filler 20 is aligned with the base plate 12, the glass plate 13x is positioned seamlessly. Therefore, even when using a panel member 11x of a different type than the tile-based panel member 11, the front panel 10 can be installed easily and with a good appearance by using the same parting member 30 and spring member 40.

For example, as shown in FIG. 10, in a panel member 11x, a glass plate 13x is attached to a base plate 11 via a mounting bracket 150. A cutout 32a is provided at the upper end of the back surface 32 of the parting member 30. The cutout 32a is provided to prevent interference between the back surface 32 and the mounting bracket 150. A similar cutout may also be provided at the lower end of the back surface 32.

The front panel 10 can be fitted with a panel member 11 attached to the base 60 from the front side between the mirror cabinet 6 and the washbasin main body 5, just as when the partition member 30 is not provided.

This embodiment is merely an example and does not limit the disclosed technology in any way. Therefore, the disclosed technology is naturally open to various improvements and modifications within the scope of its gist. For example, the front panel 10 can be used on installation objects other than the bathroom vanity 1, such as a counter panel installed at the rear of a system kitchen. The mirror cabinet 6 does not have to be present. The faucet 8 and handle 9 may be located elsewhere than the mirror cabinet 6, such as on the bathroom vanity body 5.

The parting member 30 may not have a rear portion 33. However, in that case, it cannot be used inverted. In that case, the second spring member mounting portion 35 on the end surface portion 31 functions in place of the first spring member mounting portion 34 on the rear portion 33. A spring member that is more compact than the spring member 40 is attached to the second spring member mounting portion 35. This is to prevent the spring member from protruding forward from the end surface portion 31. The parting member 30 may have the length L1 of the end surface portion 31 and the length L2 of the rear portion 33 the same. The parting member 30 may have only one of the first spring member mounting portion 34 and the second spring member mounting portion 35.

The front panel 10 may not have a foam sealant 50. The cutout 32a provided in the back surface 32 may be provided in only one of the upper and lower end portions of the back surface 32. For example, in a parting member 30 that is only applied to panel members that do not use mounting hardware 150, the cutout 32a may not be provided in the back surface 32.

As shown in FIG. 11 , the reinforcing frame 101 may be fixed to the panel member 11 as shown in the front panel 110. When the base 60 is positioned inside the end face 11c of the panel member 11, the reinforcing frame 101 is fixed to the back face 11b of the panel member 11 along the end face 11a of the panel member 11. The position of the end face 101a of the reinforcing frame 101 may be aligned with the position of the end face 11c of the panel member 11. A flat plate 102 may be fixed to the end face 101a of the reinforcing frame 101 and the end face 11c of the panel member 11. The flat plate 102 covers the step between the end face 101a of the reinforcing frame 101 and the end face 11c of the panel member 11, and forms an attachment surface for the filler 20. The spring member 40 may be attached to the flat plate 102.

As shown in the front panel 210 in Figure 12, when the spring member 240 is fixed to the base 60, a dedicated spring member may be prepared as the spring member 240 depending on the type of panel member 11 and the position of the base 60.

As in the front panel 310 shown in FIG. 13, the filler 320 may have a second front portion 323. The second front portion 323 is provided so as to extend from the portion where the insertion portion 21 and front portion 22 are connected to the opposite side of the front portion 22. The front portion 22 and the second front portion 323 are provided side by side on the same plane. A step portion 313a may be provided on the surface 11d of the main board 311. The step of the step portion 313a may be set to the same value as the thickness of the second front portion 323. The filler 320 is fixed to the main board 311 with the second front portion 323 positioned on the step portion 313a. The second front portion 323 and front portion 22 are arranged on the same plane as the surface 11d of the main board 311. The second front portion 323 and front portion 22 may be decorated in the same way as the decorative plate 313.

Instead of filler 20, the front panel 10 may use filler 320 shown in Figure 13. In this case, the second front portion 323 may be placed over the surface 11d of the panel member 11. Because the filler 320 is thin, the step formed between the second front portion 323 and the surface 11d of the panel member 11 is small and inconspicuous.

The glass plate 13x shown in Figures 8 and 9 may be a mirror.
