[0008] Embodiments of the disclosed technology will be described in detail with reference to the attached drawings. This embodiment applies the disclosed technology to a washbasin 1 shown in Figure 1. The washbasin 1 has an overall box shape, with a washbasin unit 2 attached to the top. A door 3 is provided below the washbasin unit 2 in the washbasin 1. This allows the user to use the internal space of the washbasin 1 as storage space. The washbasin 1 is an example of an interior box that is installed in a living space with its back facing a wall.

[0009] As shown in Figure 2, the back of the washbasin 1 is covered by a back panel 5. Protrusions 6-9 are provided on all four sides of the back panel 5. The protrusions 6-9 together form a rectangular frame. A back support beam 10 is positioned between the left protrusion 6 and the right protrusion 7. The back support beam 10 is a strength member that is thicker than the back panel 5. The washbasin 1 is fixed to the wall between the back support beam 10 and the wall. The back of the washbasin 1 shown in Figure 2 is the surface facing the wall and is a surface that users do not normally see after the washbasin 1 has been installed.

[0010] As shown in Figures 3 and 4, the washbasin 1 has left and right side panels 11 and 12 and a bottom panel 13. These are structural members that make up the structure of the washbasin 1. Figure 3 is a cross-sectional view of the washbasin 1 at the center in the left-right direction, and Figure 4 is a horizontal cross-sectional view at the height position where the back support beam 10 is located. As shown in Figure 3, the washbasin 1 is placed on the floor 16 with the back surface, which is the side surface of the back panel 5 and back support beam 10, facing the wall 15.

[0011] This section describes the washbasin 1 during the delivery stage after factory shipment and before installation. At this stage, the part of the washbasin 1 excluding the back support beam 10 will be referred to as the box body. There are two forms of the washbasin 1 during the delivery stage. In the first form of the washbasin 1, as shown in Figure 5, the box body 17 and the back support beam 10 are separated during the delivery stage. The back support beam 10 is not positioned at all relative to the box body 17.

[0012] In the second form of the washbasin 1, during the delivery stage, the back support beam 10 is positioned just above the protruding portion 9 on the lower edge, as shown in Figure 6. However, it is not fixed in this position. When viewed as a single unit, the back support beam 10 in the second form is composed of a main support beam 18 and a reinforcing beam 19, as shown in Figure 7. In Figure 6, it is the reinforcing beam 19 that is in contact with the protruding portion 9. The back support beam 10 in Figure 7 further has a pair of thin, protruding projections 20 at both ends.

[0013] In the second form of the washbasin 1, as shown in Figure 6, a groove 21 is provided between the back panel 5 and the protruding portion 7 on the right side. As shown in Figure 8, a groove 21 is also provided between the protruding portion 6 on the left side and the back panel 5. The pair of grooves 21 are provided on the opposing surfaces 22 where the protruding portions 6 and 7 face each other. The grooves 21 are recessed from the opposing surfaces 22. The position where the grooves 21 are formed is closer to the wall than the back panel 5. The grooves 21 are provided along the vertical direction of the protruding portions 6 and 7, from the upper end to the lower end. The width and depth of the grooves 21 are such that the projection 20 can be housed and slid vertically in Figure 6. In other words, the size of the projection 20 is such that it is inserted into the grooves 21.

[0014] In Figure 6, the back support beam 10 is in a state where a pair of projections 20 are inserted into a pair of grooves 21. This back support beam 10 does not separate from the box body 17. However, the back support beam 10 is slidable up and down along the grooves 21. In other words, in the second embodiment, the back support beam 10 is not positioned vertically during the shipping stage. This holding structure of the back support beam 10 can be achieved by placing the back support beam 10 against the back panel 5 before the projections 6-9, and then attaching the projections 6-9 on top of it. Alternatively, it can be achieved by attaching the projections 6, 7, and 9 to the back panel 5, inserting the back support beam 10 from above, and then attaching the projections 8 on the upper edge.

[0015] In the first embodiment shown in Figure 5, the back support beam 10 lacks the projection 20, but is otherwise similar to that shown in Figure 7. In the first embodiment, the projections 6 and 7 do not require grooves 21.

[0016] The construction method of the washbasin 1 in the embodiment will be described. In the description of the construction method, regarding the distinction between the first form and the second form, it will only be mentioned in situations where the distinction is necessary. When the washbasin 1 arrives at the construction site, as described above, the back crosspiece 10 is in a state where it is not positioned, at least in the vertical direction.

[0017] What the constructor does first is to determine the position for fixing the back crosspiece 10. What is required as the fixing position of the back crosspiece 10 is to satisfy the following two conditions. The first condition is that it is a position where there is a reinforcing material inside the wall 15. The second condition is that it is a position that does not obstruct the pipe 23 between the wash unit 2 and the wall 15 (see Fig. 9). However, the second condition is unnecessary in a construction site where the connection of the wash unit 2 is made between the floor 16 instead of between the wall 15. Especially in the case of a renovation property, it is often impossible to know these conditions without being on-site. The constructor looks at the situation of the wall 15 on-site and determines the height-direction position for fixing the back crosspiece 10.

[0018] Next, the constructor fixes the back crosspiece 10 at the determined height position. In the case of the first form, the constructor places and fixes the back crosspiece 10, which has been delivered in a separated state from the box body 17, at the location of the determined height position on the back panel 5. In the case of the second form, the constructor slides the back crosspiece 10 and fixes it to the back panel 5 at the determined height position. The method of fixing itself can be anything such as screwing, using an adhesive, using double-sided tape, or tacking. By the constructor fixing the back crosspiece 10 in this way, the back crosspiece 10 is fixed at a position facing the location where there is a reinforcing material in the wall 15. The back crosspiece 10 is fixed at a position avoiding the position where the pipe between the wash unit 2 and the wall 15 passes through.

[0019] The installer then drills pilot holes in the back battens 10. To do this, the installer marks the positions for the pilot holes on the back battens 10 with markings 24 (see Figure 7). The installer then drills pilot holes from the outside at the positions marked with markings 24 using a drill or other means. The installer drills the pilot holes so that they penetrate both the back battens 10 and the back panel 5. In Figure 7, the markings 24 are placed at the boundary between the main battens 18 and the bracing battens 19, but this is just one example. The positions for drilling pilot holes are arbitrary, except for positions along the edges of the back battens 10.

[0020] The back battens 10 may have markings 24 already applied at the factory before shipment. Furthermore, the back battens 10 may have pre-drilled holes at the factory before shipment. If the back battens 10 already have pre-drilled holes, then only the back panel 5 needs to be drilled during the on-site pre-drilling work. Even in this case, the drilling work is performed from the outside after the back battens 10 have been fixed in place. The installer also drills pre-drilled holes in the wall 15. The positions of the pre-drilled holes in the wall 15 naturally correspond to the positions of the pre-drilled holes in the fixed back battens 10. These positions correspond to the locations where reinforcing material is located inside the wall 15.

[0021] The installer cuts a window in the back panel 5 for passing the pipes 23 through, if necessary. The installer then places the washbasin 1 in its installation position. Naturally, the installer places the back of the washbasin 1 facing the wall 15. With the washbasin 1 in this position, the protruding parts 6-9, the back support beam 10, and the rear ends of the side panels 11 and 12 are in contact with the wall 15, or very close to it.

[0022] As a result, the pilot holes for the back support beam 10 and the back panel 5 align with the pilot holes for the wall 15. With the door 3 open, the installer fastens the washbasin 1 from the inside. At this point, the installer can see the pilot holes for the back panel 5 and simply drives the screws into them. In this way, the installer can achieve the state shown in Figure 10, where the back support beam 10 is fixed to the wall 15 by screws 26 that pass through the pilot holes 25 of the back support beam 10. In this state, the washbasin 1 is fixed in place through the fixing of the back support beam 10 to the wall 15. After that, the installer connects the piping 23. The above is the procedure for installing the washbasin 1.

[0023] As described in detail above, according to this embodiment, in a washbasin 1 installed in a living space with its back facing a wall, the back support beam 10 is not fixed to the box body 17 during the delivery stage before installation. This allows the back support beam 10 to be fixed on-site in an appropriate position according to the site conditions, and a washbasin 1 that can be installed in the installation location is realized along with the installation method. In this embodiment, there is no need for a renovation board and living space is not sacrificed. Comparing the first and second embodiments, the first embodiment is superior in that the manufacturing of the back support beam 10 and the protrusions 6 and 7 is easy. The second embodiment is superior in that there is no risk of the back support beam 10 being lost during delivery.

[0024] This embodiment is merely illustrative and does not limit the disclosed technology in any way. Therefore, the disclosed technology can naturally be improved and modified in various ways without departing from its essence. For example, in the first embodiment, the total length of the back support beam 10 does not necessarily have to extend from the protruding portion 6 to the protruding portion 7. The installer does not necessarily have to fix the back support beam 10 to the back panel 5 horizontally. The installer may fix the back support beam 10 vertically or diagonally at their discretion on site.

[0025] In the second embodiment, the pair of grooves 21 may be provided on the protrusions 8 and 9 instead of the protrusions 6 and 7. In other words, the back support beam 10 may be held vertically and be able to slide horizontally. In the second embodiment, the positions of the grooves 21 and the protrusions 20 do not have to be adjacent to the back panel 5. They may be at any position within the thickness range of the back support beam 10 and the protrusions 6 and 7.

[0026] In either the first or second form, the back support beam 10 does not have to be configured with the main support beam 18 and the bracing beam 19 shown in Figure 7. It may not have the bracing beam 19. The protruding parts 6-9 do not have to be independent parts. The protruding parts 6-9 may be the parts of structural members such as the side panels 11 and 12 that protrude towards the wall 15 side from the back panel 5. The back panel 5 does not have to cover the entire back surface of the box body 17. There may be open parts as long as there is enough area to fix the back support beam 10.

[0027] The washbasin 1 may be a composite type having a door 3 and a drawer 4 as shown in Figure 11. It may also be a full-slide type with a drawer that extends across the entire width. The disclosed technology is also applicable to types of interior boxes other than the washbasin 1 shown as an embodiment. Examples include washbasins with mirrors, storage boxes without a washbasin unit 2, and kitchen boxes equipped with a cooking sink, dishwasher, or stove instead of a washbasin unit 2. It is not essential that the internal space can be used by the user as storage space. [Explanation of Symbols]
