  2. Description of the Related Art Conventionally, as described in Patent Document 1, for example, a bathroom unit having a ceiling panel formed only of foamed resin is known.

  In this way, by forming the ceiling panel only with foamed resin without using a hard metal plate material, etc., it is possible to realize a lightweight and highly heat-insulating ceiling panel, reducing the load when carrying the ceiling panel, It is possible to suppress the occurrence of condensation on the ceiling panel during use in the bathroom.

JP-A-11-270163

  Here, when further reducing the weight of the ceiling panel and improving the heat insulation, it is conceivable that the ceiling panel is formed of a foamed resin having a very high foaming ratio. However, if the expansion ratio is very large, the rigidity of the ceiling panel is reduced. As in the bathroom unit described in Patent Document 1, screws are screwed into the ceiling panel to attach the side wall panel (corner frame, It becomes impossible to tighten and fix the flat frame) and the ceiling panel.

  The present invention has been made based on recognition of such a problem, and even if the ceiling is formed of a foamed resin having a high expansion ratio, the ceiling can be fixed above the side wall without using screws such as screws. Is to provide a comfortable bathroom unit.

  In order to solve the above-described problems, a bathroom unit according to the present invention includes a bottom, a side wall standing on a peripheral edge of the bottom so as to surround the bottom, and a ceiling that covers an upper opening formed by the side wall. And a pressing surface that presses the side peripheral surface of the ceiling inwardly is provided at an upper end portion of the side wall so as to surround the side peripheral surface of the ceiling, and the ceiling is formed of a foamed resin. In addition, the peripheral edge of the ceiling is formed to be large in advance so as to be press-fitted into the compression space surrounded by the pressing surface from above, and the ceiling is The surface is fixed to the upper end of the side wall by being pressed inward by the pressing surface of the side wall.

In the bathroom unit according to the present invention, the peripheral edge of the ceiling is positioned outside the compression space so that the compression space surrounded by the pressing surface that presses the side peripheral surface of the ceiling inward can be press-fitted from above. A large size is formed in advance. A ceiling made of foamed resin with a high expansion ratio is relatively large and easily elastically deformed. By using this ceiling, the ceiling can be pressed into the compression space from above and fixed to the side wall. it can. That is, the movement of the ceiling in the horizontal direction is regulated by the pressing surface of the side wall, and the movement of the ceiling in the vertical direction is regulated by the frictional force acting between the pressing surface and the side peripheral surface of the ceiling. Without using screws, the ceiling can be fixed to the upper end of the side wall.

In addition, a ceiling formed of a foamed resin having a high expansion ratio has a large shrinkage error during molding and tends to vary in the size of the ceiling. Since the ceiling is compressed and fixed by pressing, such an error can be absorbed. Therefore, even if the ceiling is made of a foamed resin having a high expansion ratio, it is possible to avoid a situation in which the ceiling cannot be fixed due to the influence of shrinkage errors during molding.

  In the bathroom unit according to the present invention, the side wall is erected on the peripheral edge of the bottom so as to have a rectangular shape when viewed from the top, and the upper end of the side wall is externally seen from the side when viewed from the top. It is also preferable that a deformation preventing means for preventing the protrusion from being deformed in a convex direction is provided.

When the ceiling is pressed inward by the pressing surface provided at the upper end of the side wall, the side wall is pressed outward from the ceiling by reaction. For this reason, the side walls erected so as to have a rectangular shape in the top view may be deformed in a convex shape toward the outside in the top view. In this preferred embodiment, by providing the deformation preventing means, it is possible to prevent such deformation that occurs at the upper end of the side wall. Therefore, it is possible to fix the ceiling to the upper end of the side wall without using screws on the ceiling while maintaining the aesthetics in the bathroom unit.

Moreover, in the bathroom unit according to the present invention, the deformation preventing means is a deformation preventing device formed so as to have a reverse U-shaped cross section so as to form a recess and to extend along the upper side of the side wall. In addition, it is also preferable that the deformation preventing tool is fixed to the side wall in a state where the concave portion is fitted in the upper end portion of the side wall.

In this preferred embodiment, the deformation preventing device is fixed in a state in which the recess of the deformation preventing device formed so as to have an inverted U-shaped cross section and extend along the upper side of the side wall is fitted into the upper end of the side wall. Therefore, the deformation preventing device can prevent the upper end portion of the side wall from being deformed outwardly in a top view. Therefore, the deformation of the side wall can be prevented with the deformation preventing tool having a simple structure.

  Further, in the bathroom unit according to the present invention, the deformation preventing device has a bulging portion that bulges into the bathroom space, and the ceiling is fixed to the upper end of the side wall, It is also preferable that the lower portion of the ceiling has a first projecting portion that is disposed below the bulging portion and projects outward so as to be able to contact the lower surface of the bulging portion.

A large external force may be applied to the ceiling of the bathroom unit upward from the lower surface of the ceiling, for example, when the user cleans the ceiling. In this preferable aspect, even if such an external force is generated, the first protruding portion is in contact with the lower surface of the bulging portion of the deformation preventing device, and it is possible to more reliably prevent the ceiling from moving upward. it can. In addition, since the bulging portion is provided in the deformation prevention tool, it is not necessary to separately provide a member having the bulging portion, so that the deformation of the ceiling and the more reliable movement upward of the ceiling are prevented with a simple structure. be able to.

  Further, in the bathroom unit according to the present invention, a second projecting portion projecting outward can be provided on the upper portion of the ceiling, the second projecting portion projecting outward, which can abut against a contacted portion provided on the side wall. preferable.

In this preferred embodiment, the ceiling only needs to be press-fitted until the second projecting portion comes into contact with the contacted portion provided on the side wall. Therefore, when the ceiling is press-fitted into the compression space, the ceiling is moved downward more than necessary. Therefore, it is possible to prevent the height of the ceiling from being lowered.

  According to the bathroom unit of the present invention, it is possible to provide a bathroom unit capable of fixing the ceiling to the upper side of the side wall without using screws such as screws even if the ceiling is formed of a foamed resin having a high expansion ratio. it can.

  The bathroom unit UB shown in FIG. 1 includes a bottom 100, a side wall W, and a ceiling 400 (shown by a broken line in FIG. 1 so that the structure inside the bathroom unit can be seen). The bottom part 100 has a bathtub 110 and a washing floor 120. Moreover, the side wall W has the support | pillar 200 and the wall panel 300 (illustration is abbreviate | omitted in FIG. 1, see FIG. 4 so that the structure inside a bathroom can be understood.).

Support legs 111 are provided in the vicinity of the four corners on the lower back surface of the bathtub 110, and the bathtub 110 is installed on a bathroom installation surface (for example, a building floor) via the support legs 6. The support leg 111 has a structure whose height can be adjusted by rotating the bolt part.

  The washing floor 120 is formed in a shallow vessel shape (bread shape) whose peripheral edge is bent upward, and has a waterproof property that prevents hot water from leaking out of the bathroom. And it is installed on the bathroom installation surface via the support leg 121 which has a structure which can adjust height by rotating a bolt part.

  A plurality of support columns 200 whose lower ends are fixed to the peripheral edge portion 101 are erected on the peripheral edge portion 101 of the bottom portion 100 at a predetermined interval. Similarly, a plurality of wall panels 300 are erected on the peripheral edge portion 101 of the bottom portion 100, and the left and right end portions 303 and 304 of these wall panels 300 are supported by adjacent struts 200. The peripheral edge portion 101 is erected. Here, the peripheral part 101 refers to the peripheral part of the bottom part 100. If the peripheral part 101 is a part where the support column 200 and the wall panel 300 are erected, the peripheral part of the bathtub 110 or the washing floor 120 is used as in this embodiment. Is also included in part of the peripheral edge 101.

  Here, the structure of the support column 200 and the wall panel 300 and the connection structure of the support column 200 and the wall panel 300 will be described with reference to FIG. FIG. 2 is a cross-sectional view showing a fitting structure between the two wall panels 300 and the column 200 in the present embodiment. In FIG. 2, the cross section along the direction orthogonal to the standing direction of the support | pillar 200 is shown. FIG. 2A illustrates a fitting structure of two wall panels 300 adjacent on the same plane and a support column 200 provided therebetween. FIG. 2B illustrates a fitting structure between two wall panels 300 orthogonal to each other at the corners and a support column 200 provided therebetween.

The wall panel 300 is configured by laminating a thin steel plate 320 on the surface of a thick gypsum board 310. Moreover, the support | pillar 200 is comprised so that it may become the hollow structure which bent the thin plate, and the folding | returning part 210 on either side has spring property.

  FIG. 2A illustrates an attached state of the two wall panels 300. On the left and right side portions of the steel plates 320 of the two wall panels 300, there are provided folded portions 321 to the back side having spring properties, respectively. In order to attach the two wall panels 300 to the column 200, the folded portion 321 is fitted between the left and right folded portions 210 of the column 200. The folded portion 321 is fitted so as to push the space between the left and right folded portions 210. When the folded portion 321 is fitted, the two wall panels 300 are fixed to the same plane with the support column 200 interposed therebetween.

  FIG. 2B illustrates the mounting state of the two wall panels 300 that are orthogonal to each other. However, the basic mounting structure is the same as that in FIG. 2A except that the mounting angles of the two wall panels 300 are different. Since this is adopted, the description is omitted. When the folded-back portion 321 is fitted, the two wall panels 300 are fixed in a state of being orthogonal to each other with the column 200 interposed therebetween. In this way, the side wall W is erected on the peripheral edge portion 101 of the bottom portion 100 so as to surround the bottom portion 100, and constitutes the four side surfaces of the bathroom unit UB.

A deformation preventing tool 500 is fixed to the upper end WU of the side wall W. Specifically, the deformation preventing tool 500 is fixed to the upper end portion 301 of the wall panel 300 with screws 700. FIG. 3 is a side view of the wall panel 300 to which the deformation preventing device 500 is fixed. In FIG. 3, the cross section along the standing direction of the wall panel 300 is shown. FIG. 4 is an exploded perspective view in which only the deformation preventing device 500 and the ceiling 400 of the bathroom unit UB are disassembled. As shown in FIG. 3, the deformation preventing device 500 (deformation preventing means) includes a horizontal portion 510, a first hanging portion 520 that extends downward from one end side of the horizontal portion 510, and a downward direction from the other end side of the horizontal portion 510. A metal fitting made of a metal such as aluminum or a hard resin such as ABS having a second hanging portion 530 extending and having an inverted U-shaped cross section. The deformation preventing device 500 is configured such that a recess 700 formed by the horizontal portion 510, the first hanging portion 520, and the second hanging portion 530 is fitted into the upper end portion WU of the side wall W from above with a screw 700. It is fixed with. As shown in FIG. 4, the deformation preventing device 500 is configured to extend along the upper side of the side wall W, and the upper end of the side wall W so as to cover all of the sides of the side wall W forming a rectangle when viewed from above. It is attached to the part WU.

A bulging portion 521 bulging inward of the bathroom is provided at the lower portion of the first hanging portion 520 of the deformation preventing device 500. The bulging portion 521 is formed to have a trapezoidal cross section, whereby the first inclined surface 523 is formed on the upper surface of the bulging portion 521, the second inclined surface is formed on the lower surface, and the side surface is formed. A pressing surface 522 is formed. In a state where the deformation preventing device 500 is fixed to all the upper end portions WU of the side wall W, a space surrounded by the pressing surface 522 of the deformation preventing device 500 is configured as a compression space S in which the ceiling 400 is press-fitted and compressed. The

  Subsequently, the ceiling 400 will be described with reference to FIGS. 4 and 5. FIG. 5 is a perspective view of the ceiling 400, FIG. 5A is a perspective view of the ceiling 400 viewed from above, and FIG. 5B is a perspective view of the ceiling 400 viewed from below. The ceiling 400 is made of, for example, a foamed resin such as EPP (foamed polypropylene) or EPS (foamed polystyrene). The ceiling 400 is made of, for example, a foamed resin having a foaming ratio of 5 to 30 times in order to realize high lightness and heat insulation. The ceiling 400 covers the opening 600 formed above by the side walls W constituting the four side surfaces of the bathroom unit UB.

  The ceiling 400 includes a flat rectangular parallelepiped base 410 serving as a core, a second flange-shaped projecting portion 430 projecting outward from the upper end of the base 410 in a flange shape, and a flange-shaped outer portion from the lower end of the base 410. And a first flange-shaped protrusion 420 protruding in the direction. The lower side of the base 410 is configured as a press-fit portion 411 that is press-fitted into the compression space S from above, and a part of the press-fit portion 411 is pressed by the side peripheral surface 414 in a state where the ceiling 400 is fixed to the side wall W. It is comprised as the compression part 412 pressed and compressed by the surface 522 inside bathroom space.

The second flange-shaped projecting portion 430 projects so that the outer contour of the second flange-shaped projecting portion 430 substantially coincides with the outer contour of the wall panel 300 after assembly, and the projecting length of the first flange-shaped projecting portion 420. Is formed smaller than the projecting length of the second flange-shaped projecting portion 430. If the ceiling 400 is press-fitted until the second flange-like projecting portion 430 comes into contact with the upper surface of the horizontal portion 510 of the deformation prevention device 500 fixed to the wall panel 300, the press-fit portion 411 is press-fitted to a desired height. It is configured.

  FIG. 6 is a diagram schematically illustrating a state in which the bathroom unit UB before the ceiling 400 is press-fitted into the compression space S is viewed from above. In FIG. 6, a broken line N indicates an outline of the compression unit 412 before being compressed by the side wall W. As shown in FIG. 6, the compression part 412 in the ceiling 400 is formed in advance so that the peripheral part 413 of the compression part 412 is located outside the compression space S. With this configuration, the compression unit 412 of the ceiling 400 can be press-fitted into the compression space S.

Next, a method for press-fitting the ceiling 400 into the compression space S will be described with reference to FIG. FIG. 7 is a side view schematically showing the state before and after the press-fitting of the ceiling 400, FIG. 7 (A) shows a state before press-fitting, and FIG. 7 (B) shows a state after press-fitting. . After the column 200 and the wall panel 300 are erected on the bottom 100, the ceiling 400 is press-fitted into the compression space S from above as shown in FIG. Moreover, the ceiling 400 is press-fitted downward until the second flange-shaped protruding portion 430 contacts the upper surface of the horizontal portion 510 of the deformation prevention device 500 fixed to the wall panel 300. In the state where the press-fitting is completed, the compression portion 412 of the ceiling 400 is pressed inward by the pressing surface 522 of the bulging portion 521 of the deformation prevention device 500 and the ceiling 400 is fixed to the side wall W as shown in FIG. Is done. That is, the movement of the ceiling 400 in the horizontal direction is restricted by the side wall W, and the movement of the ceiling 400 in the vertical direction (vertical direction) is caused by the frictional force acting between the compression part 412 of the ceiling 400 and the side wall W. Be regulated. Therefore, the ceiling 400 can be fixed to the upper end portion of the side wall W without using screws such as screws for the ceiling 400. Moreover, the ceiling 400 can be fixed to the side wall W by a simple operation of press-fitting downward into the compression space S. Furthermore, the ceiling 400 formed of a foamed resin with a high expansion ratio has a large shrinkage error during molding, and a large variation in the size of the ceiling 400 tends to occur. Since it is formed to be larger than S, such an error can be absorbed by the deformation of the compression portion 412 generated by being compressed by the pressing surface 522. Therefore, even if it is the ceiling 400 formed of the foaming resin having a high expansion ratio, it is possible to avoid a situation in which the ceiling 400 cannot be fixed due to the shrinkage error during molding.

Here, with reference to FIG. 8, the pressing state to the compression part 412 by the pressing surface 522 in the state which pressed the compression part 412 into the compression space S is demonstrated more concretely. FIG. 8 is a top view schematically showing a state where the compression unit 412 is press-fitted into the compression space S. FIG. In FIG. 8, for the convenience of explanation, with respect to the ceiling 400, only the compression part 412 is shown in cross section. As shown in FIG. 8, the compression portion 412 press-fitted into the compression space S is pressed inwardly from the periphery as indicated by a black arrow by the pressing surface 522. Since the compression part 412 is formed of a foamed resin having a high expansion ratio, it has a relatively high elasticity and is fixed to the side wall W in a state of being elastically deformed. Therefore, the pressing surface 522 pressing the compression part 412 is pressed outward from the compression part 412 as indicated by the white arrow in FIG. For this reason, the central portion WM in the upper end WU of the side wall W forming a rectangle in the top view may be deformed outwardly in the top view, but the bathroom according to the present embodiment In the unit UB, since the deformation preventing device 500 is fixed to the upper end WU of the side wall W, such deformation that may occur in the upper end WU of the side wall W can be prevented. Therefore, it is possible to prevent the side wall W from being deformed and the aesthetics in the bathroom unit from being deteriorated, so that the aesthetics in the bathroom unit UB can be maintained.

Moreover, in the bathroom unit UB which concerns on this embodiment, a cross-section is formed in a reverse U shape, and it is a side wall by the top view by the deformation | transformation prevention tool 500 of the simple structure comprised so that it might extend along the upper side of the side wall W. It is possible to prevent the deformation such that W is convex outward.

  Further, after the construction of the bathroom unit UB, a large external force may be applied to the ceiling 400 upward from the lower surface of the ceiling 400 when the user cleans the ceiling 400, for example. In the bathroom unit UB, in a state where the ceiling 400 is fixed to the side wall W, the first flange-shaped projecting portion 420 is located below the bulging portion 521 and the lower surface (second inclined surface 524) of the bulging portion 521. ) Comes into contact with the upper surface of the first flange-shaped projecting portion 420, so that the upward movement of the ceiling 400 can be prevented more reliably. That is, even if a very large external force is applied to the ceiling 400 from below so that the ceiling 400 moves upward against the frictional force generated between the compression portion 412 and the side wall W, the bottom surface of the bulging portion 521 Thus, the upper surface of the first flange-shaped protrusion 420 is caught, and the upward movement of the ceiling 400 can be prevented more reliably.

Furthermore, in the present embodiment, since the second flange-shaped protrusion 430 that can contact the upper surface of the horizontal portion 510 of the deformation prevention device 500 is provided on the top of the ceiling 400, the ceiling 400 is compressed. When press-fitting into the space S, it is possible to prevent the ceiling 400 from being moved to the lower side than necessary, and the height of the space in the bathroom unit UB to be lower than a desired height.

Furthermore, in this embodiment, since the 1st inclined surface 523 which inclines and descends toward the inside of bathroom space from the side wall W side is formed in the upper surface of the bulging part 521, the ceiling 400 is press-fit in the compression space S. At this time, it becomes easy to press-fit the press-fitting part 411.

Moreover, in this embodiment, since the 2nd inclined surface 524 which inclines and inclines toward the inside of bathroom space from the side wall W side is formed in the lower surface of the bulging part 521, when removing the ceiling 400 from the side wall W, The first flange-shaped protrusion 420 caught on the bulging portion 521 can be easily pulled upward from the bulging portion 521.

In addition, as a method of press-fitting the press-fitting part 411 into the compression space S, the ceiling 400 may be pressed into the compression space S from the upper side to the lower side from outside the bathroom space, or an inspection port penetrating the ceiling 400 vertically. After the ceiling 400 is provided on the ceiling 400 and the ceiling 400 is placed on the side wall W, the upper body is taken out from the bathroom space through the inspection port, and the ceiling 400 is pushed downward from above to press-fit. May be. In addition, a hook recess is formed at the lower end of the ceiling 400, and after placing the ceiling 400 on the side wall W, the finger is hooked into the hook recess from the bathroom space, and the ceiling 400 is lowered from the bathroom space. It may be drawn into and pressed into.

  In the bathroom unit UB according to the present embodiment, the pressing surface 522 is formed by the deformation preventing device 500 fixed to the side wall W, but the bathroom unit according to the present invention is not limited to this, for example, The surface of the wall panel 300 facing the bathroom space may be formed as a pressing surface.

  Further, in the bathroom unit UB according to the present embodiment, the second flange-like protruding portion 430 is configured to contact the upper surface of the horizontal portion 510 of the deformation preventing device 500 fixed to the side wall W. The bathroom unit according to the invention is not limited to this, and may be configured to contact the upper surface of the wall panel 300, for example.
