[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 6-16799 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, the protective cover described in Patent Document 1 has a structure in which a lid is fitted to a base that is in close contact with the surface of a wall. Therefore, the entire protective cover protrudes from the surface of the wall. As a result, there are problems such as poor appearance and poor space efficiency around the protective cover. [Means for solving the problem]

[0005] A wall-embedded piping cover for solving the above-mentioned problems comprises a base member having an accommodating recess that is inserted into a slit formed in a wall, has an opening that opens toward the front side of the wall, and accommodates a pipe extending in the extension direction of the slit, and flange portions formed on both sides of the accommodating recess in the width direction and fixed to the wall in a state overlapped on the surface of the wall, a flat decorative cover assembled to the base member, covers the opening and is overlapped on the flange portions, and a reinforcing member having a reinforcing recess that accommodates the accommodating recess, and reinforcing flange portions formed on both sides of the reinforcing recess in the width direction and fixed to the wall in a state overlapped on the surface of the wall.

[0006] According to this configuration, the base member is attached to the wall with the housing recess inserted into the slit formed in the wall and the flange portion overlapping the surface of the wall, thereby making it possible to keep the protruding height of the base member from the surface of the wall small. Effect of the Invention

[0007] According to the present invention, the protruding height of the piping cover from the surface of the wall can be kept small. [Brief description of the drawings]

[0011] Next, each component of the piping 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.

[0012] The accommodating recess 21 has a long, flat bottom wall 22 and a pair of opposing side walls 23 that are bent and extend from both widthwise edges of the bottom wall 22. Both outer surfaces of the side walls 23 are planar and parallel to each other.

[0013] An opening 21a of the accommodating 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 throughout the entire longitudinal direction.

[0014] The first ridges 24 face each other, the second ridges 25 face each other, and the third ridges 26 face each other in the width direction of the accommodating 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 is provided with a plurality of screw holes 28 spaced apart from one another.

[0015] The first base member 20 is integrally formed 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 accommodating 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.

[0016] The cover body 31 has a rectangular shape when viewed from the front. Both widthwise ends of the cover body 31 are curved so that the outer sides in the widthwise direction are positioned toward the rear side of the cover body 31. Each protrusion 32 extends along the longitudinal direction of the cover body 31 over the entire longitudinal direction.

[0017] The ridges 32 are inclined so as to approach each other as they move away from the cover body 31 . A locking claw 33 is formed at the tip of each protrusion 32. The locking claws 33 are inclined so as to move away from each other as they move away from the cover body 31.

[0018] 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 body 31 and each flange portion 27.

[0019] The first decorative cover 30 is integrally molded from a hard resin material. The first decorative cover 30 of the present embodiment is formed by extrusion molding. <Reinforcing member 34> As shown in FIG. 1, the reinforcing member 34 has a reinforcing recess 35 that accommodates the accommodating recess 21 of the first base member 20, and a pair of reinforcing flanges 38 formed on both sides of the reinforcing recess 35 in the width direction.

[0020] 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.

[0021] Each reinforcing flange portion 38 extends outward in the width direction of the reinforcing recess 35 from the tip end portion of each side wall 37. Each reinforcing flange portion 38 is provided with a plurality of screw holes 39 spaced apart from one another.

[0022] 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 as a piping member 80, and flange portions 47 formed on both sides of the accommodating recess 41. As shown in FIG.

[0023] The accommodation recess 41 has a bottom wall 42 and a side wall 43 that is bent and extends from an edge of the bottom wall 42 and has an inverted U-shape when viewed from the front. An opening 41 a of the accommodating recess 41 is formed by the inner surface of the tip end of the side wall 43 .

[0024] As shown in FIG. 5, a recess 42a is formed on the surface of the bottom wall 42 to allow the rear portion of the joint 82 to escape. A plurality of screw holes 45 are formed at intervals in the bottom wall 42 around the recess 42a.

[0025] The flange portion 47 extends from the outer surface of the tip of the side wall 43 outward in the width direction 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.

[0026] The second base member 40 has extensions 44 extending from both the bottom wall 42 and the side walls 43 towards 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.

[0027] <Second cosmetic 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 accommodating recess 41 and is overlapped with the flange portion 47, and a plurality of engagement claws 52 formed on the back surface of the cover body 51.

[0028] The cover body 51 has a generally rectangular shape when viewed from the front. Of the four edges of the cover 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.

[0029] When the second decorative cover 50 is attached to the second base member 40, the end edge 51b is located on the outer circumferential 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.

[0030] 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 the present embodiment is formed by injection molding.

[0031] <Support member 60> As shown in Figures 1, 2 and 4, the support member 60 is removably 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.

[0032] The base plate 61 has a rectangular shape when viewed from the front, and has a long hole 61a that is long in the longitudinal direction of the base plate 61 formed in the center thereof. 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 in a front view. In this embodiment, the pair of corners 61c are located at the upper left and lower right in a front view when attached to the first base member 20.

[0033] A pair of fitting projections 61d are formed on both ends of the surface of the base plate 61 in the longitudinal direction. As shown in Fig. 4, both longitudinal end portions 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. 4.

[0034] 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 brought into 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.

[0035] 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.

[0036] Furthermore, when the support member 60 is rotated to the normal assembly position indicated by the solid lines in FIG. 2, the pair of corners 61b come into contact with the pair of side walls 23, thereby preventing the support member 60 from rotating any further. On the other hand, rotation of the support member 60 in the counterclockwise direction in front view from the attitude shown by the two-dot chain line in FIG.

[0037] The pair of regulating protrusions 62 regulate the fitting allowance when both longitudinal ends of the base plate 61 are fitted between the bottom wall 22 of the first base member 20 and a 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.

[0038] 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 for supporting the pipe 81. The support portion 63 is provided across the entire base plate 61 in the width direction.

[0039] 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 overlaid on the first decorative cover 30, and has a cover body 71 and a flange 76.

[0040] The cover body 71 has a rectangular shape when viewed from the front, and has 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 move away from the first base member 20 as it moves away from the first decorative cover 30 in the extending direction of the first decorative cover 30 (the up-down direction in FIG. 1).

[0041] A first extending portion 72a that extends in the extending direction and is overlapped with the first decorative cover 30 is provided adjacent to one end (the upper end in FIG. 1) of the inclined portion 72b of the opposing wall 72 in the extending direction.

[0042] A second extending portion 72c extending in the above-mentioned extending direction is connected to the other end (the lower end in FIG. 1) of the inclined portion 72b of the opposing wall 72 in the above-mentioned extending direction. The opposing wall 72 has a rear surface provided with a pair of plate-shaped protrusions 74 capable of supporting the first decorative cover 30 from below in the vertical direction.

[0043] The pair of protruding portions 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 above-mentioned extending direction.

[0044] 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 each locking portion 75 engaging with each third protrusion 26 of the first base member 20.

[0045] The portions between the opposing wall 72 and each side wall 73 are curved so as to approach the first base member 20 toward the outer sides 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 to the first base member 20. The flange 76 is provided across the entire second extending portion 72c in the width direction.

[0046] The end cover 70 is integrally formed from a hard resin material by injection molding. <How to install the pipe cover 10> Next, a method for installing the piping cover 10 will be described with reference to Fig. 8 to Fig. 13. In this embodiment, a method for installing the piping cover 10 that houses the piping members 80 extending upward from piping arranged under the floor of a house or the like, that is, from so-called underfloor piping, will be described.

[0047] First, as shown in FIG. 8, a slit 91 extending in the up-down direction is formed in a wall 90. The slit 91 extends to the bottom of the wall 90 .

[0048] 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.

[0049] The pull-out hole 99 penetrates in the thickness direction through a first floor material 98a and a second floor material 98b that constitute 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.

[0050] 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 .

[0051] Next, a pair of splints 92 and a reinforcing plate 93 having a U-shaped inner circumference are fixed to the periphery of the slit 91 on the back surface of the wall 90. More specifically, the splints 92 made of a pair of square timbers are fixed to both sides of the wall 90 in the width direction of the slit 91. Also, the reinforcing plate 93 is fixed to the periphery of the upper end of the slit 91. A screw 94 is inserted from the front side into a hole 90a formed in the wall 90 and screwed into the splint 92 and reinforcing plate 93, thereby fixing the splint 92 and reinforcing plate 93 to the wall 90.

[0052] 9, the second base member 40 is inserted into the upper portion 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 opens toward 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 overlapped on the surface of the wall 90. More specifically, the screws 95 are inserted into the screw holes 48 of the flange portions 47 from the front side, and the screws 95 are screwed into the wall 90 and the reinforcing plate 93, thereby fixing the second base member 40 to the wall 90.

[0053] Next, the reinforcing member 34 is attached to the first base member 20. At this time, a pair of cutout portions 27a are formed by cutting out predetermined portions of the pair of flange portions 27 of the first base member 20 in the extension direction using a saw or the like. The dimension of the cutout portions 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 flange portions 38 are inserted into the pair of cutout portions 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 cutout portions 27a in the extension direction is covered by the reinforcing recess 35.

[0054] 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 portion 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 opens toward the front side of the wall 90. The pair of flange portions 27 and the reinforcing flange portion 38 are fixed to the wall 90 in a state where they are overlapped on the surface of the wall 90. More specifically, screws 96 are inserted from the front side into 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.

[0055] An 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 accommodating recess 21 of the first base member 20, and the joint 82 is accommodated in the accommodating 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 accommodating recess 21. Specifically, the pipe 81 is fastened to the support members 60 via a cable tie (not shown) inserted into the long hole 61a of the support members 60.

[0056] Furthermore, a screw 97 is inserted into a mounting seat (not shown) of the joint 82 and screwed into the screw 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 toward the front side of the wall 90 directly above the floor surface 98c. The pipe 81 thus drawn to the front side of the wall 90 through the opening 21a of the accommodation recess 21 is then drawn to the space G under the floor through the drawing hole 99.

[0057] 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.

[0058] Further, 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 a floor surface 98c. At this time, the flange 76 faces the floor surface 98c (see FIG. 12(b)).

[0059] 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.

[0060] 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 accommodating recess 21, and the drawing hole 99.

[0061] Next, the effects of this embodiment will be described. (1-1) The accommodating recesses 21, 41 of the base members 20, 40 are inserted into the slits 91 formed in the wall 90, and the flange portions 27, 47 are assembled to the wall 90 in a state where they are 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.

[0062] Incidentally, the pipe 81 constituting the piping member 80 is pulled out from the storage recess 21 of the first base member 20 to the space G under the floor. Here, as shown in Fig. 13, depending on the construction site, a structural body 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 pulled out from the storage recess 21 of the first base member 20 may interfere with the structural body F.

[0063] 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. Also, the floor materials 98a, 98b are formed with draw-out holes 99 for drawing out the drawn-out pipe 81 into the space G under the floor. Then, by inserting the pipe 81 through the draw-out hole 99, interference between the pipe 81 and the structural body F can be avoided.

[0064] According to the above configuration, the portion of the pipe 81 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, since 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 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.

[0065] (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 is capable of supporting the first decorative cover 30 from below in the vertical direction.

[0066] 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 a predetermined assembly position due to falling.

[0067] (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.

[0068] If the extraction hole 99 formed in the floor materials 98a and 98b becomes too large, the entire extraction hole 99 may not be covered by the cover body 71. In this regard, according to the above configuration, in addition to the cover body 71, the extraction hole 99 is covered by the flange 76 protruding from the cover body 71. This makes it possible to suitably cover the extraction hole 99 without increasing the size of the cover body 71.

[0069] (1-4) The length of the first base member 20 and the first decorative cover 30 constituting the piping cover 10 is determined according to the length of the piping member 80 to be housed. At the construction site, a worker cuts 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, and performs construction. 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.

[0070] 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.

[0071] (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 is 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.

[0072] Furthermore, according to the above configuration, the outer surfaces of the pair of side walls 23 constituting 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 run along the side surfaces of the pair of splints 92 arranged on both sides of the slit 91. This allows the first base member 20 to be positioned relative to the wall 90. This makes it possible to improve the ease of construction when fixing the first base member 20 to the wall 90.

[0073] (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.

[0074] (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. According to this configuration, when fixing each flange portion 27 to the wall 90, the screws 94 already installed in the wall 90 can be visually observed through the screw holes 28. Therefore, installing the screws 96 in positions that overlap the screws 94 can be avoided.

[0075] In addition, when cutting the first base member 20 of a fixed length to a specified 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.

[0076] (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 makes it possible to effectively prevent cracks from occurring in the wall 90.

[0077] (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 an arc shape when viewed from the front as in this embodiment or a rectangular shape when viewed from the front, the accommodating recess 41 of the second base member 40 can be inserted for construction.

[0078] (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 in a state where it is overlapped on the surface of the wall 90.

[0079] 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 slits 91 are provided is reinforced by the reinforcing member 34. Therefore, the strength of the wall 90 can be increased.

[0080] (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. According to this configuration, a part of the extraction hole 99 is covered by the wall 90, and the area of ​​the part of the extraction hole 99 that is formed on the floor 98 of the room can be reduced. Therefore, the area of ​​the part 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.

[0081] <Second embodiment> Next, a second embodiment of the wall-embedded type pipe cover will be described with reference to FIG. 14, focusing on the differences from the first embodiment.

[0082] In this embodiment, configurations that are the same as or correspond to those in the first embodiment will be denoted by the symbol "1**", which is obtained by adding "100" to each symbol "**" in this embodiment, and redundant explanations will be omitted.

[0083] As shown in FIG. 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.

[0084] Although not shown, the pipe cover 110 includes a support member and an end cover. Next, each component of the pipe cover 110 will be described in detail.

[0085] <First base member 120> The first base member 120 includes an accommodating recess 121 for collectively accommodating the pipes 181a, 181b of the piping members 180a, 180b, and a pair of flanges 127 formed on both sides of the accommodating recess 121 in the width direction.

[0086] 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 inside of the accommodating recess 121 into two. 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.

[0087] The first base member 120 is integrally molded from a hard resin material by extrusion molding. <First decorative cover 130> As indicated by the two-dot chain line in FIG. 14, the first decorative cover 130 covers the opening 121a of the accommodating recess 121 and has a flat cover body 131 that is overlapped with the flange portion 127.

[0088] The first decorative cover 130 is integrally formed from a hard resin material by extrusion molding. <Second base member 140> The accommodating recess 141 of the second base member 140 collectively accommodates the joints 182a, 182b which are connected to the pipes 181a, 181b, respectively.

[0089] The accommodating recess 141 has a bottom wall 142 and a side wall 143 that is bent and extends from an edge of the bottom wall 142 and has an inverted U-shape when viewed from the front. An opening 141 a of the accommodating recess 141 is formed by the inner surface of the tip of the side wall 143 .

[0090] 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 in a portion of the bottom wall 142 surrounding the recess 142a, into which screws (not shown) for fixing the joint 182a are screwed.

[0091] Additionally, a plurality of (three in this embodiment) screw holes 145b are formed at intervals in a portion of the bottom wall 142 surrounding the recess 142b, into which screws (not shown) for fixing the joint 182b are screwed.

[0092] Here, connection ports 183a, 183b of the joints 182a, 182b to which the pipes 181a, 181b are connected have axes L1, L2, respectively. The screw holes 145a, 145b are provided such that the distance between the axes L1, L2 increases as they move away from the first base member 120 in the extension direction of the first base member 120 (the vertical direction in the figure), that is, toward the upper side.

[0093] In this case, the pipes 181a, 181b connected to the connection ports 183a, 183b are gently bent between the first base member 120 and the second base member 140. As a result, the pipes 181a, 181b are accommodated in the accommodating recess 121 of the first base member 120 in a parallel orientation to each other.

[0094] 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 cosmetic cover 150> As indicated by the two-dot chain line in FIG. 14, the second decorative cover 150 covers the opening 141a of the accommodating recess 141 and has a flat cover body 151 that is overlapped with the flange portion 147.

[0095] 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 .

[0096] The cover body 151 is provided with two insertion holes 151c for inserting two connection ports of a mixer faucet which are respectively connected to the two joints 182a, 182b. Here, the distance D between the two insertion holes 151c, that is, 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.

[0097] The second decorative cover 150 is integrally molded from a hard resin material. The second decorative cover 150 of this embodiment is formed by injection molding. Next, the effects of this embodiment will be described.

[0098] (2-1) Even when accommodating two piping members 180a, 180b constituting 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.

[0099] (2-2) The distance D between the two insertion holes 151c is less than 200 mm. According to this configuration, a mixer faucet that complies with existing standards can be connected to the two joints 182a, 182b.

[0100] (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 becomes larger as the distance between the axes L1, L2 increases away from the first base member 120 in the extension direction of the first base member 120.

[0101] According to this configuration, when the two joints 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 joints 182a, 182b increases as they move away from the first base member 120 in the extension direction of the first base member 120. Therefore, while setting the distance between the two pipes 181a, 181b small, the distance between the connection ports provided on the opposite side of the connection ports 183a, 183b in the two joints 182a, 182b can be increased. Therefore, a mixer faucet of an existing standard can be connected to the two joints 182a, 182b while suppressing an increase in the size of the first base member 120.

[0102] <Example of change> The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other to the extent that they are not technically inconsistent.

[0103] 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 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.

[0104] The reinforcing plate 93 may 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, the 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.

[0105] 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, the number of reinforcing members 34 attached to the first base member 20 is one. However, two or more reinforcing members 34 may be attached to the first base member 20.

[0106] The reinforcing member 34 may 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 screwed in. At this time, as shown in Fig. 10 for example, it is preferable to form protrusions 29 extending along the longitudinal direction (the vertical direction in the figure) on the surface of each flange portion 27 as markers for the positions where the screws 96 are screwed in.

[0107] 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 for covering the cut surface 31a at the upper end of the first decorative cover 30 may be provided.

[0108] 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 the support members 60 can be changed as appropriate. Also, the support members 60 can be omitted.

[0109] The shape of the end cover 70 in the first embodiment can be changed as follows: Note that the end cover 70 is shown from the back side in Figures 15, 16, and 17. That is, as shown in Fig. 15, the pair of protruding parts 74 can be omitted. In this case, for example, the first extending part 72a may be attached to the first decorative cover 30 with double-sided tape or the like.

[0110] 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 vertical direction in FIG. 16). According to this configuration, when the facing 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 simultaneously superimpose the facing wall 72 of the end cover 70 on the first decorative cover 30 and prevent the first decorative cover 30 from falling.

[0111] Also, as shown in FIG. 17, the flange 76 may be omitted. In the first embodiment, the piping cover 10 that houses the piping members 80 extending upward from the underfloor piping has been described, but the present invention can also be embodied as a piping cover that houses piping members extending downward from piping arranged above the ceiling, that is, ceiling piping. In this case, an extraction hole having a configuration similar to that of the extraction hole 99 may be provided in the ceiling surface.

[0112] 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 according to the piping state of the piping members 180a, 180b constituting the hot water supply pipe and the cold water supply pipe.

[0113] 18, L-shaped elbow joints 184a, 184b may be provided between pipes 181a, 181b extending in the vertical direction and joints 182a, 182b arranged such that axes L1, L2 of connection ports 183a, 183b extend in the width direction. In this case, the size of the second base member 140A in the width direction is larger than the size of the first base member 120 in the width direction. The second base member 140 and the first base member 120 are generally T-shaped when viewed from the front.

[0114] 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.

[0115] 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.

[0116] In the second embodiment, a piping cover 110 is described that houses piping members 180a, 180b constituting a hot water supply pipe and a cold water supply pipe extending upward from an underfloor piping. However, the present invention can also be embodied as a piping cover that houses a hot water supply pipe and a cold water supply pipe extending downward from a ceiling piping.

[0117] 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.

[0118] (Note on Means to Solve the Problem) Means for solving the above problems include the following (Additional Items 1 to 4) which are technical ideas that can be grasped from the above embodiment and its modified examples.

[0119] (Additional note 1) a base member including: an accommodating recess that is inserted into a slit formed in a 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 of being overlapped on the surface of the wall; a flat decorative cover that is attached to the base member, covers the opening, and is overlapped with the flange portion; A reinforcing plate having a U-shaped inner peripheral shape and fixed to the peripheral portion of the slit on the back surface of the wall to reinforce the peripheral portion. Wall-mounted pipe cover.

[0120] (Effect of Supplementary Item 1) When an external force acts on the wall due to an earthquake or the like, stress is concentrated at the ends of the slits in their extension direction, which can cause cracks.

[0121] In this respect, according to the above-mentioned configuration, the reinforcing plate reinforces the periphery of the slit. In particular, since the reinforcing plate has a U-shaped inner circumference, the load acting on the reinforcing plate is dispersed. This makes it possible to suppress the concentration of stress on the reinforcing plate and, in turn, on the end of the slit in the extension direction. Therefore, it is possible to suppress the occurrence of cracks in the wall.

[0122] (Additional note 2) a base member including an accommodating recess having an opening that opens toward the front side of the wall and that accommodates two piping members constituting a hot water supply pipe and a cold water supply pipe, and a flange portion formed on both sides in the width direction of the accommodating recess and fixed to the wall in a state of being overlapped on the surface of the wall; a flat decorative cover that is attached to the base member, covers the opening, and is overlapped with the flange portion; Wall-mounted pipe cover.

[0123] (Effect of Supplementary Item 2) According to this configuration, even when accommodating two piping members constituting a hot water supply pipe and a cold water supply pipe, the protruding height of the piping cover from the surface of the wall can be kept small.

[0124] (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-embedded piping cover as described in appended paragraph 2.

[0125] (Effect of Supplementary Item 3) According to this configuration, a mixer faucet that complies with existing standards 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 such that a distance between axes of connection ports to which the pipes are connected in the two joints increases as the connection ports move away from the first base member in the extension direction of the first base member. A wall-embedded pipe cover as described in appended paragraph 3.

[0126] (Effect of Supplementary Item 4) According to this configuration, when the two joints are fixed to the second base member with screws, the distance between the axes of the connection ports of the two joints increases as they move away from the first base member in the extension direction of the first base member. Therefore, it is possible to set the distance between the two pipes to be small while increasing the distance between the connection ports provided on the opposite side of the connection ports of the two joints. Therefore, it is possible to connect a mixer faucet of an existing standard to the two joints while suppressing an increase in the size of the first base member. [Explanation of symbols]
