[0011] First Embodiment Hereinafter, a first embodiment of a wall-embedded type pipe cover will be described with reference to FIGS.

[0012] As shown in FIG. 1, the wall-mounted pipe cover (hereinafter referred to as pipe cover 10) includes a first base member 20, a first decorative cover 30, a reinforcing member 34, a second base member 40, a second decorative cover 50, a support member 60, and an end cover 70.

[0013] Next, each component of the pipe cover 10 will be described in detail. <First base member 20> As shown in Figures 1, 2 and 4, the first base member 20 has a gutter-shaped accommodating recess 21 that accommodates a pipe 81 as a piping member 80, and a pair of flange portions 27 formed on both sides of the accommodating recess 21 in the width direction.

[0014] The accommodation recess 21 has a long, flat bottom wall 22 and a pair of opposing side walls 23 that bend and extend from both widthwise edges of the bottom wall 22. The outer surfaces of both side walls 23 are flat and parallel to each other.

[0015] An opening 21a of the accommodation recess 21 is formed between the tip ends of the pair of side walls 23. On the inner surface of each side wall 23, in order from closest to the bottom wall 22, a pair of first ridges 24, a pair of second ridges 25, and a pair of third ridges 26 extend along the longitudinal direction of the bottom wall 22 and over the entire longitudinal direction.

[0016] The first ridges 24, the second ridges 25, and the third ridges 26 face each other in the width direction of the receiving recess 21. Each flange portion 27 extends outward in the width direction of the accommodating recess 21 from the outer surface of the tip of each side wall 23. Each flange portion 27 has a plurality of screw holes 28 formed therein at intervals.

[0017] The first base member 20 is integrally molded from a hard resin material by extrusion molding. <First decorative cover 30> As shown in Figures 1, 3 and 4, the first decorative cover 30 has a flat cover body 31 that covers the opening 21a of the storage recess 21 and is overlapped with the flange portion 27, and a pair of protrusions 32 formed on the back surface of the cover body 31.

[0018] The cover body 31 has a rectangular shape when viewed from the front. Both widthwise edges of the cover body 31 are curved so that the outer edges in the widthwise direction are positioned closer to the back side of the cover body 31. Each of the ridges 32 extends along the longitudinal direction of the cover body 31 over the entire longitudinal direction.

[0019] The protrusions 32 are inclined so that the farther they are from the cover body 31, the closer they become to each other. A locking claw 33 is formed at the tip of each protrusion 32. The locking claws 33 are inclined so that the further they are from the cover body 31, the more they move away from each other.

[0020] Both ends of the first decorative cover 30 in the longitudinal direction are cut surfaces 31a. 4, the first decorative cover 30 is assembled to the first base member 20 by engaging the locking claws 33 with the third ridges 26 of the first base member 20. At this time, a gap S is formed between the cover main body 31 and each flange portion 27.

[0021] The first decorative cover 30 is integrally molded from a hard resin material by extrusion molding. <Reinforcing member 34> As shown in FIG. 1, the reinforcing member 34 has a reinforcing recess 35 that accommodates the accommodation recess 21 of the first base member 20, and a pair of reinforcing flange portions 38 formed on both sides of the reinforcing recess 35 in the width direction.

[0022] The reinforcing recess 35 has a flat bottom wall 36 and a pair of opposing flat side walls 37 that are bent and extend from both widthwise edges of the bottom wall 36 . An opening 35a of the reinforcing recess 35 is formed between the tip ends of the pair of side walls 37. The length of the opening 35a in the width direction is slightly larger than the length of the accommodating recess 21 in the width direction.

[0023] Each reinforcing flange 38 extends outward in the width direction of the reinforcing recess 35 from the tip of each side wall 37. Each reinforcing flange 38 has a plurality of screw holes 39 formed at intervals.

[0024] The reinforcing member 34 is integrally formed from a metal material. <Second base member 40> As shown in FIGS. 1 and 5, the second base member 40 includes an accommodating recess 41 for accommodating a joint 82 serving as a piping member 80, and flange portions 47 formed on both sides of the accommodating recess 41. As shown in FIG.

[0025] The accommodation recess 41 has a bottom wall 42 and a side wall 43 that is bent and extends from the edge of the bottom wall 42 and has an inverted U-shape when viewed from the front. An opening 41 a of the accommodation recess 41 is formed by the inner surface of the tip of the side wall 43 .

[0026] As shown in FIG. 5, a recess 42a is formed on the surface of the bottom wall 42 to allow the back of the joint 82 to escape. A plurality of screw holes 45 are formed at intervals around the recess 42a in the bottom wall 42.

[0027] The flange portion 47 extends outward in the width direction from the outer surface of the tip of the side wall 43 and toward the opposite side from the first base member 20. The flange portion 47 is provided with a plurality of screw holes 48 and a plurality of engagement holes 49 spaced apart from one another.

[0028] The second base member 40 has extensions 44 extending from both the bottom wall 42 and the side wall 43 toward the first base member 20 side. The second base member 40 is integrally molded from a hard resin material. In this embodiment, the second base member 40 is formed by injection molding.

[0029] <Second decorative cover 50> As shown in Figures 1 and 6, the second decorative cover 50 has a flat cover body 51 that covers the opening 41a of the storage recess 41 and is superimposed on the flange portion 47, and a plurality of locking claws 52 formed on the back surface of the cover body 51.

[0030] The cover body 51 has a generally rectangular shape when viewed from the front. Of the four edges of the cover main body 51, three edges 51b, excluding an edge 51a that overlaps with the first decorative cover 30, are bent and protrude toward the rear side.

[0031] When the second decorative cover 50 is attached to the second base member 40, the end edge 51b is located on the outer periphery side of the flange portion 47 of the second base member 40. An insertion hole 51c is provided in the center of the cover body 51 for inserting a water faucet or the like connected to the joint 82.

[0032] Each of the locking claws 52 is provided at a position corresponding to each of the engagement holes 49 of the second base member 40 . The second decorative cover 50 is integrally molded from a hard resin material. The second decorative cover 50 of this embodiment is formed by injection molding.

[0033] <Support member 60> As shown in Figures 1, 2 and 4, the support member 60 is detachably attached to the first base member 20 and supports the pipe 81, and has a base plate 61, a pair of regulating protrusions 62 protruding from the surface of the base plate 61, and a support portion 63 protruding from the surface of the base plate 61 and supporting the pipe 81.

[0034] The base plate 61 has a rectangular shape when viewed from the front, and has a slot 61a formed in the center thereof that is long in the longitudinal direction of the base plate 61. A pair of corners 61b at diagonal positions of the base plate 61 are right-angled, while the remaining pair of corners 61c are rounded into an arc shape when viewed from the front. In this embodiment, the pair of corners 61c are located at the upper left and lower right when viewed from the front when attached to the first base member 20.

[0035] A pair of fitting protrusions 61d are formed on both ends of the surface of the base plate 61 in the longitudinal direction. 4, both longitudinal ends of the base plate 61 are fitted between the bottom wall 22 of the first base member 20 and the pair of first protrusions 24, thereby attaching the support member 60 to the first base member 20. Note that the fitting protrusions 61d are not shown in FIG.

[0036] 2, with the longitudinal direction of the support member 60 aligned with the longitudinal direction of the first base member 20, the support member 60 is rotated 90 degrees clockwise in a front view while being in contact with the bottom wall 22. As a result, both longitudinal end portions of the base plate 61, more specifically, the portions where the pair of fitting protrusions 61d are provided, are fitted between the bottom wall 22 of the first base member 20 and the pair of first ridges 24.

[0037] As described above, the pair of corners 61c of the base plate 61 are rounded into an arc shape when viewed from the front, which allows the support member 60 to rotate clockwise when viewed from the front from the position shown by the two-dot chain line in Fig. 2.

[0038] Furthermore, when the support member 60 is rotated to the normal assembly position shown by the solid lines in FIG. 2, the pair of corners 61b come into contact with the pair of side walls 23, thereby preventing further rotation of the support member 60. On the other hand, the pair of corners 61b abut against the pair of side walls 23, thereby preventing the support member 60 from rotating counterclockwise in front view from the attitude shown by the two-dot chain line in FIG.

[0039] The pair of regulating protrusions 62 regulate the insertion allowance when both longitudinal ends of the base plate 61 are inserted between the bottom wall 22 of the first base member 20 and the pair of first protrusions 24, and are provided on both longitudinal sides of the base plate 61 and extend along the width direction of the base plate 61.

[0040] The support portion 63 is provided in the center of the base plate 61 in the longitudinal direction, and has a concave surface with an arc-shaped cross section on its surface that supports the pipe 81. The support portion 63 is provided across the entire width of the base plate 61.

[0041] The support member 60 is integrally molded from a hard resin material by injection molding. <End cover 70> As shown in Figures 1, 7(a) and 7(b), the end cover 70 covers the opening 21a of the accommodating recess 21 and is superimposed on the first decorative cover 30, and has a cover main body 71 and a flange 76.

[0042] The cover body 71 has a rectangular shape when viewed from the front, and includes an opposing wall 72 that faces the first base member 20, and a pair of side walls 73 formed on both sides of the opposing wall 72 in the width direction. The opposing wall 72 has an inclined portion 72b that is inclined so as to become more distant from the first base member 20 as it becomes farther away from the first decorative cover 30 in the extending direction of the first decorative cover 30 (the vertical direction in FIG. 1).

[0043] A first extending portion 72a extending in the extension direction and overlapping with the first decorative cover 30 is provided adjacent to one end (upper end in FIG. 1) of the inclined portion 72b of the opposing wall 72 in the extension direction.

[0044] A second extending portion 72c extending in the extension direction is connected to the other end (lower end in FIG. 1) of the inclined portion 72b of the opposing wall 72 in the extension direction. The rear surface of the opposing wall 72 is provided with a pair of plate-shaped protrusions 74 that can support the first decorative cover 30 from below in the vertical direction.

[0045] The pair of protrusions 74 extend in the extension direction of the first decorative cover 30 and are provided at an interval from each other in the width direction of the opposing wall 72. More specifically, each protrusion 74 extends over the entire inclined portion 72b and the second extending portion 72c in the extending direction.

[0046] A locking portion 75 is formed at the tip of each protrusion 74, protruding outward in the width direction of the opposing wall 72. The end cover 70 is assembled to the first base member 20 by engaging each locking portion 75 with each third ridge 26 of the first base member 20.

[0047] The portions between the opposing wall 72 and each side wall 73 are curved so as to approach the first base member 20 as they move outward in the width direction of the opposing wall 72 . The flange 76 protrudes from the edge of the second extending portion 72c opposite the inclined portion 72b toward the opposite side from the first base member 20. The flange 76 is provided across the entire width of the second extending portion 72c.

[0048] The end cover 70 is integrally molded from a hard resin material by injection molding. <Installation method for pipe cover 10> Next, a method for installing the piping cover 10 will be described with reference to Figures 8 to 13. In this embodiment, a method for installing the piping cover 10 that houses piping members 80 extending upward from piping arranged under the floor of a house or the like, so-called underfloor piping, will be described.

[0049] First, as shown in FIG. 8, a slit 91 extending in the vertical direction is formed in a wall 90. The slit 91 extends to the bottom of the wall 90 .

[0050] The upper end of the slit 91 is formed in an arc shape when viewed from the front. Next, as shown in FIGS. 8 and 13, an extraction hole 99 for extracting the piping member 80 into the space G under the floor is formed in the floor 98.

[0051] The extraction hole 99 penetrates in the thickness direction through a first floor material 98a and a second floor material 98b that make up the floor 98. The first floor material 98a is a board material that has been subjected to a surface treatment, and the second floor material 98b is a base material such as plywood.

[0052] The extraction hole 99 has a portion formed at a position overlapping the wall 90 in the thickness direction of the wall 90 , and is connected to the slit 91 . The width of the extraction hole 99 is set to be the same as the width of the slit 91 .

[0053] Next, a pair of splints 92 and a reinforcing plate 93 having a U-shaped inner periphery are fixed to the periphery of the slit 91 on the back surface of the wall 90. More specifically, the splints 92, which are made of a pair of square timbers, are fixed to both sides of the wall 90 in the width direction of the slit 91. In addition, the reinforcing plate 93 is fixed to the periphery of the upper end of the slit 91. Screws 94 are inserted from the front side into holes 90a formed in the wall 90 and screwed into the splints 92 and reinforcing plate 93, thereby fixing the splints 92 and reinforcing plate 93 to the wall 90.

[0054] 9, the second base member 40 is inserted into the upper part of the slit 91, and the flange portions 47 are fixed to the wall 90 in such a manner that the wall 90 is sandwiched between the second base member 40 and the reinforcing plate 93. The opening 41a of the accommodation recess 41 faces the front side of the wall 90. The pair of flange portions 47 are fixed to the wall 90 in a state where they are superimposed on the surface of the wall 90. More specifically, screws 95 are inserted from the front side into the screw holes 48 of the flange portions 47, and then screwed into the wall 90 and the reinforcing plate 93, thereby fixing the second base member 40 to the wall 90.

[0055] Next, the reinforcing member 34 is attached to the first base member 20. At this time, a pair of cutouts 27a are formed by cutting out predetermined portions of the pair of flanges 27 of the first base member 20 in the extension direction using a saw or the like. The dimension of the cutouts 27a in the extension direction is set to be slightly larger than the dimension of the reinforcing member 34 in the extension direction. Then, the pair of reinforcing flanges 38 are inserted into the pair of cutouts 27a, respectively, to attach the reinforcing member 34. At this time, the outer peripheral surface of the portion of the accommodating recess 21 that corresponds to the cutouts 27a in the extension direction is covered by the reinforcing recess 35.

[0056] Next, the housing recess 21 of the first base member 20 and the reinforcing recess 35 of the reinforcing member 34 are inserted into the lower part of the slit 91, and the flange portion 27 and the reinforcing flange portion 38 are fixed to the wall 90 in such a manner that the wall 90 is sandwiched between the housing recess 21 and the splint 92. At this time, the opening 21a of the housing recess 21 faces the front side of the wall 90. The pair of flange portions 27 and reinforcing flange portions 38 are fixed to the wall 90 in a state where they are superimposed on the surface of the wall 90. More specifically, screws 96 are inserted from the front side through the screw holes 28 of the flange portion 27 and the screw holes 39 of the reinforcing flange portion 38. Two of the screws 96 on the second base member 40 side (upper side) are screwed into the wall 90 and the reinforcing plate 93. The remaining screws 96 are screwed into the wall 90 and the splint 92. This fixes the first base member 20 and the reinforcing member 34 to the wall 90.

[0057] The upper end of the accommodating recess 21 of the first base member 20 overlaps with the front side of the extending portion 44 of the second base member 40. 10, the pipe 81 is accommodated in the accommodation recess 21 of the first base member 20, and the joint 82 is accommodated in the accommodation recess 41 of the second base member 40. At this time, the pipe 81 is supported by the two support members 60 attached to the accommodation recess 21. Specifically, the pipe 81 is fastened to the support members 60 via a cable tie (not shown) inserted into the elongated hole 61a of the support members 60.

[0058] Furthermore, a screw 97 is inserted into a mounting seat (not shown) of the joint 82 and screwed into the threaded hole 45 of the accommodating recess 41 , thereby fixing the joint 82 to the accommodating recess 41 . 11 and 13, the lower portion of the pipe 81 is gently bent directly above the floor surface 98c toward the front side of the wall 90. The pipe 81 thus drawn out to the front side of the wall 90 through the opening 21a of the accommodation recess 21 is then drawn out to the space G under the floor through the drawing hole 99.

[0059] Next, the first decorative cover 30 is assembled to the first base member 20. Next, the second decorative cover 50 is assembled to the second base member 40. As a result, the cut surface 31a at the upper end of the first decorative cover 30 is covered by the second decorative cover 50.

[0060] Additionally, the end cover 70 is attached so as to cover the cut surface 31a at the lower end of the first decorative cover 30. The end cover 70 is provided between the first decorative cover 30 and the floor surface 98c. At this time, the flange 76 faces the floor surface 98c (see FIG. 12(b)).

[0061] 12(a) and 12(b), the second base member 40 is entirely covered by the second decorative cover 50. The first base member 20 is entirely covered by the first decorative cover 30 and the end cover 70.

[0062] As shown in FIG. 13, the end cover 70 covers the portion of the pipe 81 that is drawn out to the front side of the wall 90 through the opening 21a of the accommodation recess 21, and the drawing hole 99.

[0063] Next, the effects of this embodiment will be described. (1-1) The base members 20, 40 are assembled to the wall 90 with the accommodating recesses 21, 41 inserted into the slits 91 formed in the wall 90 and the flanges 27, 47 superimposed on the surface of the wall 90. Therefore, the protruding height of the base members 20, 40 from the surface of the wall 90 can be kept small.

[0064] The pipe 81 constituting the piping member 80 is drawn out from the storage recess 21 of the first base member 20 into the space G under the floor. Here, as shown in FIG. 13 , depending on the construction site, a structural frame F may be provided in the space G under the floor directly below the first base member 20. In this case, there is a risk that the pipe 81 drawn out from the storage recess 21 of the first base member 20 may interfere with the structural frame F.

[0065] 13, the pipe 81 is gently bent from directly above the floor 98, so that the pipe 81 is drawn out to the front side of the wall 90 through the opening 21a of the storage recess 21. Furthermore, the floor materials 98a and 98b are formed with drawing holes 99 for drawing the drawn pipe 81 into the space G under the floor. Then, by inserting the pipe 81 through the drawing holes 99, interference between the pipe 81 and the structural body F can be avoided.

[0066] According to the above configuration, the portion of the pipe 81 that is pulled out to the front side of the wall 90 through the opening 21a of the accommodating recess 21 and the pull-out hole 99 can be covered by the end cover 70 having the opposing wall 72. Moreover, because the opposing wall 72 of the end cover 70 has the inclined portion 72b, the protruding height of the portion of the end cover 70 that is close to the first decorative cover 30 from the surface of the wall 90 can be kept small. Therefore, the protruding height of the piping cover 10 from the surface of the wall 90 can be kept small.

[0067] (1-2) The end cover 70 is provided between the first decorative cover 30 and the floor surface 98c. The end cover 70 has a protruding portion 74 that protrudes from the rear surface of the opposing wall 72 and can support the first decorative cover 30 from below in the vertical direction.

[0068] According to this configuration, when the first decorative cover 30 is assembled to the first base member 20, the protruding portion 74 of the end cover 70 prevents the first decorative cover 30 from falling due to its own weight. Therefore, it is possible to prevent the first decorative cover 30 from being displaced from the predetermined assembled position due to falling.

[0069] (1-3) The end cover 70 has a cover body 71 including an opposing wall 72, and a flange 76 that faces the floor surface 98c and protrudes from the cover body 71 toward the side opposite to the first base member 20.

[0070] If the extraction holes 99 formed in the floor materials 98a and 98b are too large, the entire extraction holes 99 may not be covered by the cover main body 71. In this regard, according to the above configuration, the extraction hole 99 is covered not only by the cover main body 71 but also by the flange 76 protruding from the cover main body 71. This makes it possible to suitably cover the extraction hole 99 without increasing the size of the cover main body 71.

[0071] (1-4) The lengths of the first base member 20 and the first decorative cover 30 constituting the piping cover 10 are determined according to the length of the piping member 80 to be housed. At the construction site, workers cut the first base member 20 and the first decorative cover 30, each having a fixed length (for example, 2 to 3 m), to a predetermined length determined according to the length of the piping member 80. Therefore, if the cut surface 31a of the first decorative cover 30 is exposed to the outside, the aesthetic appearance of the piping cover 10 may be impaired.

[0072] In this regard, according to the above configuration, the cut surface 31a of the first decorative cover 30 is covered by the end cover 70, so that the cut surface 31a is not exposed to the outside, and the appearance of the piping cover 10 can be improved.

[0073] (1-5) If a pair of splints 92 are fixed to portions of the rear surface of the wall 90 located on both sides of the slit 91 along the extending direction of the slit 91, the peripheral portion of the wall 90 around the slit 91 can be reinforced. If the flange portion 27 of the first base member 20 is fixed to such a wall 90, the flange portion 27 can be stably supported by the wall 90.

[0074] Furthermore, according to the above configuration, the outer surfaces of the pair of side walls 23 that constitute the accommodating recess 21 of the first base member 20 are planar and parallel to each other, so that the outer surfaces of the pair of side walls 23 fit along the side surfaces of the pair of splints 92 that are arranged on both sides of the slit 91. This allows the first base member 20 to be positioned relative to the wall 90. This improves the ease of installation when fixing the first base member 20 to the wall 90.

[0075] (1-6) The first decorative cover 30 has a cut surface 31 a, and the cut surface 31 a is covered by the second decorative cover 50 . According to this configuration, in a front view of the piping cover 10, the first decorative cover 30 and the second decorative cover 50 are continuous, and the cut surface 31a of the first decorative cover 30 is covered by the second decorative cover 50. Therefore, the appearance of the piping cover 10 can be improved without providing a dedicated cover for covering the cut surface 31a of the first decorative cover 30.

[0076] (1-7) Each flange portion 27 of the first base member 20 is provided with a plurality of screw holes 28 spaced apart from one another. With this configuration, when fixing each flange portion 27 to the wall 90, the screws 94 already installed in the wall 90 can be seen through the screw holes 28. This makes it possible to avoid installing screws 96 in positions that overlap with the screws 94.

[0077] Furthermore, when cutting the first base member 20 of a fixed length to a predetermined length determined according to the length of the piping member 80, the first base member 20 can be cut while checking the position of the screw 94 through the screw hole 28 of the first base member 20 so that the position of the screw 94 already installed in the wall 90 does not overlap with the position of the screw hole 28.

[0078] (1-8) The upper end of the slit 91 is formed in an arc shape when viewed from the front. This reduces stress concentration at the upper end of the slit 91 in the wall 90. This effectively prevents cracks from occurring in the wall 90.

[0079] (1-9) The outer peripheral surface of the side wall 43 of the second base member 40 is inverted U-shaped when viewed from the front. Therefore, whether the shape of the upper end of the slit 91 is arc-shaped when viewed from the front as in this embodiment or rectangular when viewed from the front, the accommodating recess 41 of the second base member 40 can be inserted for installation.

[0080] (1-10) The piping cover 10 is provided with a reinforcing member 34 having a reinforcing recess 35 that accommodates the accommodating recess 21 and a reinforcing flange portion 38 formed on both sides of the reinforcing recess 35 in the width direction and fixed to the wall 90 while being superimposed on the surface of the wall 90.

[0081] According to this configuration, the reinforcing member 34 is fixed to the wall 90 with the flange portion 38 overlapping the surface of the wall 90. Therefore, the wall 90 in which the slit 91 is provided is reinforced by the reinforcing member 34. Therefore, the strength of the wall 90 can be increased.

[0082] (1-11) The extraction hole 99 has a portion formed at a position overlapping the wall 90 in the thickness direction of the wall 90 and is connected to the slit 91. With this configuration, a portion of the extraction hole 99 is covered by the wall 90, and the area of ​​the portion of the extraction hole 99 that is formed on the indoor floor 98 can be reduced. Therefore, the area of ​​the portion of the extraction hole 99 that is covered by the end cover 70 is reduced. Therefore, the protruding height of the end cover 70 from the surface of the wall 90 can be further reduced.

[0083] Second Embodiment Next, a second embodiment of the wall-embedded pipe cover will be described with reference to FIG. 14, focusing on the differences from the first embodiment.

[0084] In this embodiment, for configurations that are the same as or correspond to those in the first embodiment, the symbol "1**" is added by adding "100" to each symbol "**" in this embodiment, thereby omitting duplicate explanations.

[0085] As shown in Figure 14, the piping cover 110 accommodates two piping members 180a, 180b that constitute a hot water supply pipe and a cold water supply pipe, and includes a first base member 120, a first decorative cover 130, a second base member 140, and a second decorative cover 150.

[0086] Although not shown, the pipe cover 110 includes a support member and an end cover. Next, each component of the piping cover 110 will be described in detail.

[0087] <First base member 120> The first base member 120 includes an accommodating recess 121 for collectively accommodating the pipes 181a and 181b of the piping members 180a and 180b, and a pair of flanges 127 formed on both sides of the accommodating recess 121 in the width direction.

[0088] A standing wall 123a is formed in the center of the accommodating recess 121 in the width direction, protruding from the bottom wall 122 and dividing the interior of the accommodating recess 121 into two sections. The standing wall 123a extends in the extension direction of the first base member 120, i.e., in the longitudinal direction of the bottom wall 122 (the up-down direction in the figure). The standing wall 123a is provided over the entire first base member 120 in the extension direction.

[0089] The first base member 120 is integrally molded from a hard resin material by extrusion molding. <First decorative cover 130> As shown by the two-dot chain line in FIG. 14, the first decorative cover 130 covers the opening 121a of the accommodation recess 121 and has a flat plate-shaped cover main body 131 that is placed on the flange portion 127.

[0090] The first decorative cover 130 is integrally molded from a hard resin material by extrusion molding. <Second base member 140> The accommodation recess 141 of the second base member 140 accommodates together the joints 182a and 182b to be connected to the pipes 181a and 181b, respectively.

[0091] The accommodation recess 141 has a bottom wall 142 and a side wall 143 that is bent and extends from the edge of the bottom wall 142 and has an inverted U-shape when viewed from the front. An opening 141 a of the accommodation recess 141 is formed by the inner surface of the tip of the side wall 143 .

[0092] The surface of the bottom wall 142 is formed with recesses 142a and 142b for allowing the rear portions of the joints 182a and 182b to escape. A plurality of (three in this embodiment) screw holes 145a are formed at intervals around the recess 142a in the bottom wall 142, into which screws (not shown) for fixing the joint 182a are screwed.

[0093] Additionally, a plurality of (three in this embodiment) screw holes 145b are formed at intervals around the recess 142b in the bottom wall 142, into which screws (not shown) for fixing the joint 182b are screwed.

[0094] Here, connection ports 183a and 183b of the joints 182a and 182b to which the pipes 181a and 181b are connected have axes L1 and L2, respectively. The screw holes 145a, 145b are provided so that the distance between the axes L1, L2 increases as they move away from the first base member 120 in the extending direction of the first base member 120 (the vertical direction in the figure), that is, toward the upper side.

[0095] In this case, the pipes 181a and 181b connected to the connection ports 183a and 183b are gently bent between the first base member 120 and the second base member 140. As a result, the pipes 181a and 181b are accommodated in the accommodation recess 121 of the first base member 120 in a parallel orientation to each other.

[0096] The second base member 140 is integrally molded from a hard resin material. In this embodiment, the second base member 140 is formed by injection molding. <Second decorative cover 150> As shown by the two-dot chain line in FIG. 14, the second decorative cover 150 covers the opening 141a of the accommodation recess 141 and has a flat plate-shaped cover main body 151 that is placed on the flange portion 147.

[0097] The cover body 151 has a generally rectangular shape when viewed from the front. An edge 151 b of the cover body 151 is located on the outer periphery side of the flange portion 147 of the second base member 140 .

[0098] The cover body 151 is provided with two insertion holes 151c for inserting two connection ports of a mixer faucet that are connected to the two joints 182a and 182b, respectively. Here, the distance D between the two insertion holes 151c, i.e., the distance D between the central axes C1, C2 of the two insertion holes 151c, is preferably 100 mm or more and less than 200 mm.More preferably, the distance D is 120 mm to 150 mm.

[0099] The second decorative cover 150 is integrally molded from a hard resin material by injection molding. Next, the effects of this embodiment will be described.

[0100] (2-1) Even when accommodating two piping members 180a, 180b that constitute a hot water supply pipe and a cold water supply pipe, the protruding height of the piping cover 110 from the surface of the wall 90 can be kept small.

[0101] (2-2) The distance D between the two insertion holes 151c is less than 200 mm. With this configuration, a mixer tap that complies with existing standards can be connected to the two joints 182a and 182b.

[0102] (2-3) The multiple screw holes 145a, 145b are arranged so that the distance between the axes L1, L2 of the connection ports 183a, 183b to which the pipes 181a, 181b of the two fittings 182a, 182b are connected increases as they move away from the first base member 120 in the extension direction of the first base member 120.

[0103] With this configuration, when the two fittings 182a, 182b are fixed to the second base member 140 using screws, the distance between the axes L1, L2 of the connection ports 183a, 183b of the two fittings 182a, 182b increases as they move away from the first base member 120 in the extension direction of the first base member 120. This makes it possible to increase the distance between the connection ports of the two fittings 182a, 182b, respectively, that are provided on the opposite sides of the connection ports 183a, 183b, while keeping the distance between the two pipes 181a, 181b small. This makes it possible to connect existing standard mixer faucets to the two fittings 182a, 182b while preventing the size of the first base member 120 from increasing.

[0104] <Example of change> The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other within the scope of technical compatibility.

[0105] The shape of the upper end of the slit 91 is not limited to an arc shape when viewed from the front. For example, the slit may be rectangular when viewed from the front. In this case, the slit can be easily formed in the wall 90. In addition, in this case, the reinforcing plate 93 is not limited to having a U-shaped inner peripheral shape, and may have an inner peripheral shape that follows the shape of the slit.

[0106] The reinforcing plate 93 can be omitted. In this case, it is preferable that the pair of splints 92 extend to the upper end of the slit 91. In the first embodiment, a pair of splints 92 are fixed to the rear surface of the wall 90, but one or both of the splints 92 may be omitted.

[0107] In the first embodiment, the position at which the reinforcing member 34 is attached to the first base member 20 may be changed as appropriate. In the first embodiment, one reinforcing member 34 is attached to the first base member 20, but two or more reinforcing members 34 may be attached to the first base member 20.

[0108] The reinforcing member 34 can be omitted. The screw holes 28 provided in each flange portion 27 of the first base member 20 may be omitted. In this case, a worker at the construction site will determine the positions in the flange portions 27 where the screws 96 are to be screwed in. In this case, as shown in FIG. 10, for example, it is preferable to form a protrusion 29 extending in the longitudinal direction (the vertical direction in the figure) on the surface of each flange portion 27 as a marker for the positions where the screws 96 are to be screwed in.

[0109] The cut surface 31a at the upper end of the first decorative cover 30 may not be covered by the second decorative cover 50. In this case, a dedicated cover may be provided to cover the cut surface 31a at the upper end of the first decorative cover 30.

[0110] The pair of side walls 23 of the first base member 20 may be closer to each other as they approach the bottom wall 22. The same applies to the second base member 40. The number of support members 60 can be changed as needed. Also, the support members 60 can be omitted.

[0111] The shape of the end cover 70 in the first embodiment can be changed as follows: Note that Fig. 15, Fig. 16, and Fig. 17 show the end cover 70 from the back side. That is, the pair of protruding portions 74 can be omitted as shown in Fig. 15. In this case, for example, the first extending portion 72a may be attached to the first decorative cover 30 with double-sided tape or the like.

[0112] As shown in FIG. 16, the pair of protruding portions 74 may have a notch 77 on one side in the extending direction (the upper side in the up-down direction in FIG. 16). According to this configuration, when the opposing wall 72 of the end cover 70 is superimposed on the first decorative cover 30 and assembled, the first decorative cover 30 is allowed to escape by the notch 77. Therefore, it is possible to achieve both superimposition of the opposing wall 72 of the end cover 70 on the first decorative cover 30 and prevention of the first decorative cover 30 from falling.

[0113] Also, as shown in FIG. 17, the flange 76 may be omitted. In the first embodiment, the piping cover 10 is described as accommodating the piping members 80 extending upward from the underfloor piping. However, the present invention can also be embodied as a piping cover that accommodates piping installed above the ceiling, i.e., piping members extending downward from the ceiling piping. In this case, an extraction hole having a configuration similar to the extraction hole 99 may be provided in the ceiling surface.

[0114] In the second embodiment, the support member and the end cover of the pipe cover 110 may be omitted. The shape of the pipe cover 110 is not limited to that exemplified in the second embodiment. That is, the shape of the pipe cover 110 can be changed as follows depending on the piping configuration of the piping members 180a, 180b that constitute the hot water supply pipe and the cold water supply pipe.

[0115] 18, L-shaped elbow joints 184a, 184b may be provided between pipes 181a, 181b extending in the vertical direction and joints 182a, 182b arranged so that axes L1, L2 of connection ports 183a, 183b extend in the width direction. In this case, the width direction size of second base member 140A is larger than the width direction size of first base member 120. The second base member 140 and the first base member 120 are T-shaped as a whole when viewed from the front.

[0116] 19, the joints 182a, 182b may be arranged so that the distance between the axes L1, L2 of the connection ports 183a, 183b is constant in the extension direction of the first base member 120. In this case, the size of the second base member 140B in the width direction is the same as the length of the first base member 120 in the width direction.

[0117] 20, the distance between the pipes 181a, 181b may be set so that the distance between the axes L1, L2 of the connection ports 183a, 183b is constant in the extension direction of the first base member 120A, and the distance D between the two insertion holes 151c is 100 mm or more and less than 200 mm. Even in this case, the accommodating recess 121A of the first base member 120A only needs to cover the pipes 181a, 181b collectively.

[0118] In the second embodiment, the piping cover 110 is described as accommodating the piping members 180a, 180b constituting the hot water supply pipe and the cold water supply pipe extending upward from the underfloor piping, but the present invention can also be embodied as a piping cover that accommodates the hot water supply pipe and the cold water supply pipe extending downward from the ceiling piping.

[0119] In the second embodiment, the pipe cover 110 that houses the hot water supply pipe and the cold water supply pipe has been described. However, the present invention can also be embodied as a pipe cover that houses, for example, a cold water supply pipe and a drain pipe.

[0120] (Note on the means to solve the problem) The means for solving the above problems include the following (Supplementary Items 1 to 4) which are technical ideas that can be grasped from the above embodiment and its modifications.

[0121] (Additional note 1) a base member including: an accommodating recess that is inserted into a slit formed in the wall, has an opening that opens toward the front side of the wall, and accommodates a piping member; and flange portions that are formed on both sides of the accommodating recess in a width direction and are fixed to the wall in a state where they are superimposed on the surface of the wall; a flat decorative cover attached to the base member, covering the opening and overlapping the flange portion; a reinforcing plate having a U-shaped inner peripheral shape and fixed to the peripheral edge of the slit on the back surface of the wall to reinforce the peripheral edge, Wall-mounted pipe cover.

[0122] (Effect of Supplementary Item 1) When an external force acts on the wall due to an earthquake or the like, stress may be concentrated at the end of the slit in the extension direction, causing cracks.

[0123] In this regard, according to the above-mentioned configuration, the reinforcing plate reinforces the peripheral edge of the slit. In particular, since the reinforcing plate has a U-shaped inner peripheral shape, the load acting on the reinforcing plate is dispersed. This prevents stress from concentrating on the reinforcing plate and, ultimately, on the end of the slit in the extension direction. Therefore, it is possible to prevent cracks from occurring in the wall.

[0124] (Additional note 2) a base member including: an accommodation recess that is inserted into a slit formed in the wall, has an opening that opens toward the front side of the wall, and accommodates two piping members that respectively constitute a hot water supply pipe and a cold water supply pipe; and flange portions that are formed on both sides of the accommodation recess in the width direction and are fixed to the wall in a state where they are overlapped on the surface of the wall; a flat decorative cover that is assembled to the base member, covers the opening, and is overlaid on the flange portion, Wall-mounted pipe cover.

[0125] (Effect of Supplementary Item 2) According to this configuration, even when two piping members constituting a hot water supply pipe and a cold water supply pipe are housed, the protruding height of the piping cover from the surface of the wall can be kept small.

[0126] (Additional note 3) the base member includes a first base member that houses two pipes that constitute the two piping members, and a second base member that houses two joints that are connected to the two pipes, respectively, and that constitute the two piping members; the decorative cover includes a first decorative cover assembled to the first base member and a second decorative cover assembled to the second base member, The second decorative cover is provided with two insertion holes for inserting two faucets to be connected to the two joints, respectively; The distance between the two insertion holes is less than 200 mm. A wall-mounted piping cover as described in appendix 2.

[0127] (Effect of Supplementary Item 3) According to this configuration, a mixer faucet of an existing standard can be connected to the two joints. (Additional note 4) The accommodating recess of the second base member is provided with a plurality of screw holes into which screws for fixing the two joints are screwed, The plurality of screw holes are provided so that the distance between the axes of the connection ports to which the pipes are connected in the two joints increases as the distance from the first base member increases in the extension direction of the first base member. A wall-mounted piping cover as described in appendix 3.

[0128] (Effect of Supplementary Item 4) According to this configuration, when the two fittings are fixed to the second base member using screws, the distance between the axes of the connection ports of the two fittings increases as they move away from the first base member in the extension direction of the first base member. Therefore, the distance between the two pipes can be set small while the distance between the connection ports on the opposite sides of the two fittings can be increased. Therefore, existing standard mixer faucets can be connected to the two fittings while preventing the size of the first base member from increasing. [Explanation of symbols]
