DETAILED DESCRIPTION OF THE INVENTION

[0008] <Embodiment 1> The bathroom fixture 1 of this embodiment is attached to a wall member 90 of bathroom B, as shown in Figures 1 and 2. In this embodiment, the bathroom fixture 1 is a handrail. The bathroom fixture 1 has a fixture main body 2. The fixture main body 2 is the gripping part of the handrail. The bathroom fixture 1 is attached to the wall member 90 with the axis of the fixture main body 2, which is in the shape of a straight tube, positioned along the front surface 90A, which is the surface of the wall member 90 facing bathroom B.

[0009] In the following description, the directions of the bathroom fixture 1 are based on the state when it is attached to the wall member 90. The front-to-back direction is defined as the direction in front of the front surface 90A of the wall member 90, and the opposite direction as the back. The up-down and left-to-right directions are defined as the direction in which the wall member 90 is viewed from inside the bathroom B. The X-axis, Y-axis, and Z-axis shown in each figure represent the front-to-back direction, left-to-right direction, and up-to-down direction, respectively. For the X-axis, Y-axis, and Z-axis, the positive directions of each axis are defined as the front, left, and up, respectively.

[0010] As shown in Figures 1 and 2, wall member 90 has a steel plate 91 and gypsum board 92. The steel plate 91 is a rigid body. The "rigid body" here means anything that has the strength required for wall member 90, and is not limited to a strictly rigid body as defined in physics. The gypsum board 92 functions as a heat insulating material for wall member 90. The gypsum board 92 is attached to one side of the steel plate 91. The surface of wall member 90 facing the steel plate 91 is positioned on the interior side of bathroom B, and the gypsum board 92 is positioned on the exterior side of bathroom B. The overall thickness of wall member 90 is approximately 10 mm.

[0011] As shown in Figures 1 to 3, bathroom fixture 1 comprises reinforcing plate 10 and fixing part 20. Reinforcing plate 10 is placed inside bathroom B on wall member 90. Reinforcing plate 10 is in the form of a thin plate. Reinforcing plate 10 is fixed to wall member 90 with screw S1. Fixing part 20 is fixed to reinforcing plate 10 with bolt S2.

[0012] As shown in FIG. 4, the reinforcing plate 10 has a rectangular shape. The reinforcing plate 10 is formed by sheet metal processing a thin metal plate, such as a 2 mm thick stainless steel plate. In this embodiment, the reinforcing plate 10 is attached to the wall member 90 with the longitudinal direction of the rectangle corresponding to the up-down direction and the lateral direction corresponding to the left-right direction. The reinforcing plate 10 has a bolt fixing portion 11 and a through hole 12. The bolt fixing portion 11 has a threaded hole into which the bolt S2 is screwed. The bolt fixing portion 11 is formed in the vertical and horizontal center of the reinforcing plate 10. An internal thread is formed on the inner peripheral surface of the hole in the bolt fixing portion 11 into which the bolt S2 is screwed.

[0013] As shown in Fig. 4, the bolt fixing portion 11 has a burring portion 11A in which the periphery of the hole is protruded toward the rear surface of the reinforcing plate 10 by burring. The internal thread in the bolt fixing portion 11 is formed continuously from the front surface of the reinforcing plate 10 to the tip of the burring portion 11A. The amount by which the burring portion 11A protrudes from the rear surface of the reinforcing plate 10 is approximately the same as the plate thickness of the reinforcing plate 10.

[0014] A screw S1 for fixing the reinforcing plate 10 to the wall member 90 is inserted into the through hole 12. The screw S1 is a tapping screw. In the present embodiment, a plurality of through holes 12 is formed. The plurality of through holes 12 are formed on both sides of the bolt fixing portion 11. Specifically, the plurality of through holes 12 are formed on both sides of the bolt fixing portion 11, at both ends of the reinforcing plate 10 in the short direction, in a row of three along the longitudinal direction of the reinforcing plate 10. That is, six through holes 12 are formed. When viewed from the bolt fixing portion 11, the number of through holes 12 on both sides in the short direction is greater than the number of through holes 12 on both sides in the long direction. Specifically, when viewed from the bolt fixing portion 11, the number of through holes 12 on both sides in the short direction is six and on both sides in the long direction.

[0015] In this embodiment, ribs 13 are formed on the reinforcing plate 10. The ribs 13 protrude from the front surface of the reinforcing plate 10 in a convex cross-section. The ribs 13 are extruded from the rear surface of the reinforcing plate 10 by press molding. The ribs 13 extend linearly along the short direction of the reinforcing plate 10. Two ribs 13 are formed. The two ribs 13 are formed on both sides of the bolt fixing portion 11 in the longitudinal direction of the reinforcing plate 10. Each rib 13 not only ensures the strength of the reinforcing plate 10, but also functions as a rotation stopper for the decorative cover 30 by contacting the inner surface of the upright wall portion 34 of the decorative cover 30 described later when the bathroom fixture 1 is attached to the wall member 90.

[0016] The reinforcing plate 10 has directional load-bearing capacity. Specifically, when comparing the load-bearing capacity of the reinforcing plate 10 against an external force acting along the longitudinal direction with the load-bearing capacity of the reinforcing plate 10 against an external force acting along the lateral direction, the load-bearing capacity in the lateral direction is greater. This is because the through holes 12 are formed on both sides of the bolt fixing portion 11 in the lateral direction, and because the ribs 13 are formed to extend along the lateral direction.

[0017] An adhesive sheet 14 is attached to the rear surface of the reinforcing plate 10. The adhesive sheet 14 is formed by applying an acrylic adhesive to both sides of a sheet-like substrate made of foamed polyethylene. Holes are formed in the adhesive sheet 14 at positions corresponding to the bolt fixing portions 11 and through holes 12 in the reinforcing plate 10.

[0018] As shown in FIG. 4, the reinforcing plate 10 has a display unit 15. The display unit 15 displays information such as characters and symbols indicating the installation direction when the reinforcing plate 10 is attached to the wall member 90, and a guide for the installation direction. In the present embodiment, the display units 15 are arranged on each of the four sides of the reinforcing plate 10. Each display unit 15 is formed by engraving on the surface of the reinforcing plate 10. Each display unit 15 has characters indicating the installation direction. The characters on each display unit 15 are displayed facing in different directions. When the reinforcing plate 10 is attached to the wall member 90 in the correct orientation, only one of the characters on each display unit 15 can be read with the upright orientation.

[0019] For example, when the reinforcing plate 10 is attached in the orientation shown in Fig. 4, only the characters on the display unit 15 located at the top of the reinforcing plate 10 are oriented upright and can be read as "vertical." This "vertical" character indicates that the attachment direction of the reinforcing plate 10 is appropriate when the fixture body 2 is attached vertically, i.e., in a direction extending up and down. In contrast, when the "horizontal" character is oriented upright, the display unit 15 indicates that this direction is appropriate as the attachment direction of the reinforcing plate 10 when the fixture body 2 is attached horizontally, i.e., in a direction extending left and right.

[0020] In the case of the bathroom fixture 1 of this embodiment, a relatively large external force acts on the fixture body 2, which is the gripping portion of the handrail, in a direction perpendicular to the extension direction. This external force acts via the fixing portion 20 to generate a bending load in the same direction on the bolt S2. The reinforcing plate 10 bears the bending load generated on this bolt S2. It is preferable that the reinforcing plate 10 is attached in a direction in which the direction in which this bending load acts matches the direction of the load-bearing capacity. The display unit 15 indicates whether the attachment direction of the reinforcing plate 10, which has a directional load-bearing capacity, matches the direction in which the relatively large external force acts.

[0021] As shown in Fig. 4, in this embodiment, the reinforcing plate 10 has scribe lines 16. The scribe lines 16 indicate a guide for alignment with reference lines such as horizontal and vertical lines. The scribe lines 16 form the display units 15. The scribe lines 16 are provided on each of the display units 15. Each of the scribe lines 16 is formed as two parallel lines spaced 1 mm apart on the outer periphery of the reinforcing plate 10, at either the center in the vertical direction or the center in the horizontal direction.

[0022] As shown in FIG. 2, the reinforcing plate 10 is covered by a decorative cover 30. The decorative cover 30 is attached to the front side of the reinforcing plate 10. As shown in FIG. 5, the decorative cover 30 has a front wall portion 31, a peripheral wall portion 32, a boss portion 33, and a standing wall portion 34. The front wall portion 31 is rectangular and slightly larger than the reinforcing plate 10. The peripheral wall portion 32 rises rearward from the periphery of the front wall portion 31. The boss portion 33 protrudes rearward from the center of the front wall portion 31 in the vertical and horizontal directions. The boss portion 33 is cylindrical. A hole penetrating from the front to the rear is formed in the center of the boss portion 33. The standing wall portion 34 rises rearward from the front wall portion 31 so as to surround the boss portion 33.

[0023] As shown in FIG. 5, a recess 31A is formed in the rear surface of the front wall 31 of the decorative cover 30. The recess 31A is recessed from the rear surface of the front wall 31 toward the front surface. A plurality of recesses 31A are formed. The plurality of recesses 31A are formed corresponding to the positions where the through holes 12 are formed in the reinforcing plate 10. When the recess 31A covers the reinforcing plate 10 attached to the wall member 90, the tip of the head of the screw S1 is housed in the recess 31A (see FIG. 2).

[0024] When the bathroom fixture 1 is assembled, the decorative cover 30 covers the front surface of the reinforcing plate 10 with the front wall portion 31 and covers the entire periphery of the end face of the reinforcing plate 10 with the peripheral wall portion 32. When the bathroom fixture 1 is assembled, the decorative cover 30 contacts the front surface 90A of the wall member 90 at the tip of the peripheral wall portion 32 and contacts the front surface of the reinforcing plate 10 at the tips of the boss portion 33 and the vertical wall portion 34. When the bathroom fixture 1 is assembled, the decorative cover 30 covers the reinforcing plate 10 so that it cannot be seen from the outside. In other words, when the bathroom fixture 1 is assembled, the reinforcing plate 10 is entirely covered by the decorative cover 30 and cannot be seen from the outside.

[0025] As shown in FIG. 1, the fixing parts 20 are attached to both ends of the appliance body 2. The fixing part 20 has a fixing part main body 21 and a cover member 22. The fixing part main body 21 forms a recess 21A that opens at the front and recesses rearward. A through hole 21B that penetrates in the front-to-rear direction is formed in the back surface of the recess 21A. A bolt S2 passes through the through hole 21B. The cover member 22 is detachably attached to the fixing part main body 21 and covers the fixing part main body 21. As shown in FIG. 2, the fixing part 20 of this embodiment is fixed to the reinforcing plate 10 with a bolt, with a decorative cover 30 sandwiched between the fixing part 20 and the reinforcing plate 10.

[0026] The procedure for installing the bathroom fixture 1 configured as above will now be described. All of the installation work below is performed by a worker from inside bathroom B. In other words, no work outside bathroom B is required to install bathroom fixture 1.

[0027] When installing the bathroom fixture 1, a through hole 90B is formed in the wall member 90, as shown in Figure 6. The position at which the through hole 90B is formed corresponds to the position of the through hole 21B in the fixing portion 20. When forming the through hole 90B, for example, the fixture main body 2 is temporarily positioned in the desired position on the front surface 90A of the wall member 90, and the position of the through hole 21B in the fixing portion 20 in this state can be used as a guide. In this embodiment, the bathroom fixture 1 has two fixing portions 20, and one through hole 21B is formed in each fixing portion 20. Therefore, one through hole 90B is formed corresponding to each fixing portion 20 that is positioned at a distance on both ends of the extension direction of the fixture main body 2.

[0028] As shown in Figure 6, the reinforcing plate 10 is attached to the front surface 90A of the wall member 90, aligning it with the position of the formed through hole 90B. In this embodiment, an adhesive sheet 14 is attached to the rear surface of the reinforcing plate 10. The reinforcing plate 10 can be temporarily fixed by attaching it to the wall member 90 using the adhesive sheet 14. At this time, the reinforcing plate 10 is positioned so that the burring portion 11A of the bolt fixing portion 11 fits into the through hole 90B. It is advisable to position the reinforcing plate 10 with its short side aligned in the direction in which external forces are expected to act when the bathroom fixture 1 is in use.

[0029] As described above, in the case of bathroom fixture 1 of this embodiment, a relatively large external force acts in a direction perpendicular to the extension direction of fixture body 2, which is the gripping portion of the handrail. Therefore, in consideration of the load-bearing direction, reinforcing plate 10 is preferably positioned so that through-holes 12 are located on both sides of the direction perpendicular to the extension direction of fixture body 2. In this embodiment, by attaching reinforcing plate 10 to wall member 90 in a direction in which the character "Tate" (vertical) on display section 15 is correctly positioned, the installation direction of reinforcing plate 10 matches the load-bearing direction of reinforcing plate 10. This makes it easy to install reinforcing plate 10 in the appropriate installation direction. When attaching reinforcing plate 10 to wall member 90, it is recommended to take waterproofing measures around through-hole 90B, such as by applying a sealant such as silicone sealant to the periphery of through-hole 90B in advance.

[0030] After the reinforcing plate 10 is attached to the wall member 90, pilot holes 90C for the screws S1 are formed in the wall member 90 in alignment with the positions of the through holes 12, as shown in Fig. 7. After the pilot holes 90C are formed, it is advisable to apply a sealant around them. It is also advisable to apply a sealant to the female threads of the bolt fixing portions 11.

[0031] As shown in FIG. 7, the screw S1 is fastened in line with the through hole 12. The screw S1 is a tapping screw, and is screwed in while forming a thread on the inner circumferential surface of the pilot hole 90C, essentially on the inner circumferential surface of the portion of the pilot hole 90C formed in the steel plate 91. The decorative cover 30 is placed over the reinforcing plate 10, and in this state the rear surface of the fixing part main body 21 is placed against the front surface of the decorative cover 30. The bolt S2 is inserted through the through hole 21B in the fixing part main body 21 and penetrates the boss portion 33 of the decorative cover 30, and is fastened to the bolt fixing part 11 (see FIG. 2). Finally, the cover member 22 is placed over the fixing part main body 21, completing the installation work.

[0032] The function and effect of the bathroom fixture 1 configured as described above will now be explained. The bathroom fixture 1 comprises a reinforcing plate 10 and a fixing part 20. The reinforcing plate 10 is arranged on the front surface 90A, which is the indoor side of the wall member 90 of the bathroom B, and is a thin plate fixed to the wall member 90 with a screw S1. The fixing part 20 is fixed to the reinforcing plate 10 with a bolt S2.

[0033] Bathroom fixture 1 is attached to wall member 90 by fastening fixing parts 20 attached to both ends of fixture body 2 to reinforcing plate 10 using bolts S2, with reinforcing plate 10 being fixed to wall member 90 with tapping screws S1. In this way, the installation of bathroom fixture 1, reinforcing plate 10 to wall member 90 and the installation of fixing parts 20 to reinforcing plate 10, can both be performed from inside bathroom B. This makes installation of bathroom fixture 1 easy.

[0034] Bathroom fixture 1 is suitable for retrofitting into an existing bathroom. For example, in the case of a fixture that attaches a fixing member to the back of a wall member, as in the aforementioned Patent Document 1, work must be done outside the bathroom. In this case, the wall member of the existing bathroom must be removed, the bathroom fixture must be installed, and then the wall member must be reassembled, which is a cumbersome process. In contrast, bathroom fixture 1 can be installed extremely easily by working only inside bathroom B.

[0035] Wall member 90 has steel plate 91, which serves as a rigid body to which reinforcing plate 10 is fixed with screws S1, located inside bathroom B. This allows for stronger fixation than, for example, when another member is interposed between the reinforcing plate and the rigid body. In this way, reinforcing plate 10 can be fixed directly to steel plate 91, which is a rigid body, and there is great significance in locating reinforcing plate 10 inside bathroom B.

[0036] The reinforcing plate 10 has a bolt fixing portion 11 and a through hole 12. The bolt fixing portion 11 fixes a bolt S2 that bolts the fixing portion 20. The through hole 12 receives a screw S1 that screw-fixes the reinforcing plate 10 to the wall member 90. In this way, the reinforcing plate 10 has a portion for fixing the fixing portion 20 and a portion for fixing the reinforcing plate 10 itself to the wall member 90, thereby enabling appropriate fixation to be achieved in each portion.

[0037] The bolt fixing portion 11 is a threaded hole into which a bolt S2 is screwed to fix the fixing portion 20. Therefore, fixing of the fixing portion 20 can be achieved with a simple configuration.

[0038] The reinforcing plate 10 has six through holes 12 formed therein. The reinforcing plate 10 is fixed to the wall member 90 by inserting a screw S1 into each of the six through holes 12 and screwing the reinforcing plate 10 to the wall member 90. This allows the reinforcing plate 10 to be firmly fixed to the wall member 90. The six through holes 12 are formed on both sides of the bolt fixing portion 11. This allows the load-bearing capacity to be further increased in both directions where the through holes 12 are located as viewed from the bolt fixing portion 11.

[0039] The number of through holes 12 formed on both sides of bolt fixing portion 11 is greater than the number of through holes 12 formed in the direction perpendicular to the direction of both sides as viewed from bolt fixing portion 11. This allows reinforcing plate 10 to easily achieve directional load-bearing capacity. Therefore, by attaching reinforcing plate 10 so that many through holes 12 are arranged in the direction in which a relatively large external force acts, the external force can be effectively absorbed. As a result, bathroom fixture 1 can improve its load-bearing capacity during use.

[0040] For example, in the case of bathroom fixture 1, which is a handrail extending in the vertical direction as in this embodiment, a relatively large external force acts in the left-right direction during use. In this case, reinforcing plate 10 is attached to wall member 90 so that the short side of reinforcing plate 10, which is the direction in which through holes 12 are aligned across bolt fixing portion 11, is aligned with the left-right direction. In this way, if the magnitude of the external force acting during use has a directional characteristic, by attaching reinforcing plate 10 so that it is oriented in that direction, the load-bearing capacity of bathroom fixture 1 during use can be improved.

[0041] The reinforcing plate 10 is provided with reinforcing ribs 13. Therefore, it is possible to ensure sufficient strength despite the thin plate shape.

[0042] Ribs 13 extend linearly along the surface of reinforcing plate 10. This allows reinforcing plate 10 to easily achieve directional load-bearing capacity. Therefore, by attaching reinforcing plate 10 so that the extension direction of ribs 13 is parallel to the direction in which a relatively large external force acts, the external force can be effectively absorbed. As a result, bathroom fixture 1 can improve its load-bearing capacity during use.

[0043] The reinforcing plate 10 has a display section 15. The display section 15 displays the mounting direction relative to the wall member 90. Therefore, the appropriate mounting direction of the reinforcing plate 10 can be easily grasped.

[0044] Bathroom fixture 1 is equipped with a decorative cover 30 that covers reinforcing plate 10. Therefore, the decorative cover with the desired design can conceal reinforcing plate 10 and the screws S1 that secure reinforcing plate 10 to wall member 90, improving the design. By providing decorative cover 30, for example, by designing the decorative cover from the perspective of design, the reinforcing plate can be designed with appropriate strength according to the required function without considering the design. In other words, a reinforcing plate with the desired strength can be easily obtained.

[0045] Bathroom fixture 1 has a structure in which fixing part 20 is bolted to bolt fixing part 11 of reinforcing plate 10. Therefore, if the fixing part of another bathroom fixture has a similar structure, reinforcing plate 10, which is screwed to wall member 90, can be easily replaced and installed without changing it.

[0046] <Other embodiments> The present disclosure is not limited to the embodiments described above and illustrated in the drawings, and the following embodiments, for example, are also included within the technical scope of the present disclosure.

[0047] The bathroom fixtures according to the present disclosure are not limited to the handrails exemplified in the above embodiments. Examples of bathroom fixtures include shower hooks for hanging shower heads, lid holders for supporting bathtub insulation lids in a suspended state, bathroom counters, bathroom shelves, bathroom baskets, and various other fixtures that can be attached to bathroom wall members. The present disclosure is particularly suitable for fixtures that are subject to relatively large external forces, such as handrails.

[0048] The configuration of the wall member according to the present disclosure is not limited to the above embodiment. When the wall member is configured such that a rigid body is disposed inside the bathroom, the rigid body may be, for example, a tile or the like other than a steel plate.

[0049] The plate material constituting the reinforcing plate is not limited to the stainless steel plate exemplified in the above embodiment. Examples of the plate material constituting the reinforcing plate include metal plates such as steel plates and aluminum plates. It is preferable that the plate material constituting the reinforcing plate has excellent corrosion resistance.

[0050] The thickness of the plate material constituting the reinforcing plate can be, for example, in the range of 1.0 mm to 3.0 mm. That is, in the present disclosure, a thin plate is intended to mean a thickness in the range of 1.0 mm to 3.0 mm. A metal plate with a thickness in this range is suitable because it can ensure sufficient strength as a reinforcing plate and can reduce the amount of protrusion from the surface of the wall member.

[0051] The form of the bolt fixing portion according to the present disclosure is not limited to the above embodiment. For example, the bolt fixing portion may be a bolt member having a male thread attached to the reinforcing plate by welding or the like. A plurality of bolt fixing portions may be formed.

[0052] In the reinforcing plate according to the present disclosure, the number of through holes is not limited to the above-described embodiment. Preferably, at least two through holes are formed. More preferably, three or more through holes are formed. In this case, it is even more preferable that the reinforcing plate has three or more through holes formed therein, and that bolt fixing portions are formed inside a polygon having the through holes as vertices.

[0053] The reinforcing plate according to the present disclosure does not necessarily have a display portion. When a display portion is provided, the number, shape, display form, etc. thereof are not limited to those of the above embodiment. The display portion may display, for example, a symbol, a figure, a pattern, etc. The display content of the display portion is not limited to content relating to the load-bearing direction of the reinforcing plate, but may be, for example, content simply relating to the direction of the installation direction. The display content of the display portion may be any content that allows the appropriate installation direction of the reinforcing plate to be understood.

[0054] It is not essential that the reinforcing plate according to the present disclosure have an adhesive sheet attached to the rear surface thereof, and the reinforcing plate may be attached directly to the wall member without an adhesive sheet or the like.

[0055] The shape, number, etc. of the fixing portion according to the present disclosure are not particularly limited. The number of fixing portions may be, for example, one for one fixture body, or three or more for one fixture body. When one fixing portion is provided for one fixture body, such as in a shower head, it is preferable to bolt the fixing portion with two or more bolts from the viewpoint of preventing rotation of the fixing portion itself. In this case, it is preferable that the number of bolt fixing portions on the reinforcing plate be equal to or greater than the number of through holes in the fixing portion.

[0056] The manner in which the fixing part is connected to the instrument body is not particularly limited. For example, the fixing part can be connected to the instrument body by bolt fixing, screw fixing, adhesive, etc. The fixing part may be provided integrally with the instrument body.

[0057] The fixture body according to the present disclosure refers to a part that can perform a function as a bathroom fixture, such as a gripping part of a handrail, a part of a shower hook for hanging a shower head, etc. The fixture body may, for example, be capable of performing two or more different functions.

[0058] The provision of a decorative cover is not essential. The bathroom fixture according to the present disclosure may have a configuration in which the fixing portion is directly bolted to the reinforcing plate.

[0059] The type of screw used to secure the reinforcing plate is not limited to that described in the above embodiment. For example, a tapping screw with a drill may be used. In this case, the reinforcing plate can be secured by the screw without forming a pilot hole for the screw.

[0060] In this disclosure, "bolt fixing" refers to the general fixing of a member having a pre-formed external thread and a member having a pre-formed internal thread, such as a bolt and nut. In contrast, "screw fixing" in this disclosure refers to the general fixing of a member that is fastened by screwing into another member that does not have a thread, such as a tapping screw, while forming a thread on the other member, such as a wall member or a plug.
