Description

[Technical field]

[0001] The present invention relates to a toilet unit that is disposed facing a wall surface of a toilet space. [Background technology]

[0002] Conventionally, there have been multi-function toilets that are designed to be accessible to wheelchair users and people with internal disabilities. In multi-function toilets, multiple pieces of equipment are placed in one toilet space to accommodate individual users, so the water supply and drainage pipes for each piece of equipment, as well as the power lines to operate the equipment, are exposed in the toilet space, making the toilet space look unattractive.

[0003] To solve this problem, a toilet unit has been proposed that has cabinets and linings that store the piping for the sanitary equipment inside and also units the sanitary equipment to be installed as a single piece of equipment, giving the multi-function toilet space a neat and tidy appearance while making it compact.

[0004] The lining unit described in Patent Document 1 includes a frame formed of multiple frame members arranged in the vertical, horizontal, and depth directions, a top plate (deck) attached to the upper surface of the frame, and a front plate attached to the front side of the frame. In such a lining unit, piping such as a water supply pipe and a drain pipe is arranged inside the frame, and sanitary equipment such as a toilet is provided in front of and behind the frame.

[0005] [Patent Document 1] JP 2012-162948 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0006] In the lining unit described in Patent Document 1, the piping and water supply tank used in the toilet space are installed to be housed within the lining unit. In particular, according to the configuration in which the piping such as the water supply pipe and the drain pipe are exposed to the outside by passing through the front plate of the lining unit, the following problems arise when the lining unit is introduced into a multi-purpose toilet space.

[0007] The front plate is a decorative plate that functions to prevent the internal space of the lining unit from being seen from the outside, and is configured to cover the front of the lining unit from the floor to the upper end of the lining unit frame. In such a case, the water supply pipe and drain pipe connected to the toilet are inserted from the front plate into the inside of the lining unit, and are supported and fixed by the frame of the lining unit. In such a case, a fixing structure is required to fix the positional relationship between the front plate and the toilet.

[0008] Specifically, the configuration for fixing the positional relationship between the front panel and the toilet can be, for example, such that a toilet support unit for fixing the toilet is erected on the floor surface, a rod-shaped bolt for fixing the toilet protrudes from the toilet support unit toward the toilet, and the rod-shaped bolt is inserted into a fixing hole on the back of the toilet to fix the toilet, thereby fixing the positional relationship between the toilet support unit and the toilet. With this configuration, the work of fixing the positional relationship between the toilet and the toilet support unit involves first removing the existing toilet, then installing and fixing the toilet support unit to the floor surface for fixing the toilet, and then fixing the water supply pipe and drain pipe installed on the back of the toilet to the toilet support unit, and then fixing the toilet to the toilet support unit, and finally connecting the toilet fixed to the toilet support unit to the water supply pipe and drain pipe, thereby completing the installation work of the lining unit.

[0009] When installing a lining unit in an existing toilet space like this, the work of removing and installing the toilet bowl and connecting the toilet bowl to the water supply and drainage pipes is cumbersome, and causes an increase in the workload involved in installing the lining unit.

[0010] The present invention has been made in consideration of such problems, and aims to provide a toilet unit that can be installed regardless of the shape of the existing toilet, allows for efficient installation work, and furthermore, keeps the toilet space neat and compact. [Means for solving the problem]

[0011] The first aspect of the present invention is a toilet unit comprising a seated toilet body installed in the space within the toilet, and a gate-shaped case that straddles the seated toilet body and stores the water supply and drainage pipes of the water supply and drainage equipment in a concealed manner.The gate-shaped case is configured in a gate shape with one core frame erected at the corner of a wall in the toilet space, the other core frame erected with the seated toilet body sandwiched between them, and an upper frame connecting the tops of each core frame, and the toilet body is straddled by each frame, characterized in that the toilet unit has the water supply and drainage pipes of the water supply and drainage equipment stored within each frame in a concealed manner.

[0012] With this toilet unit, by arranging a gate-shaped case so that it straddles the seated toilet body, when installing the lining unit in an existing toilet space, the lining unit can be installed without removing the existing toilet bowl and the water supply pipe and drain pipe connected to the toilet bowl, thereby shortening the construction time when installing the lining unit. In addition, the water supply and drainage equipment is hidden within each frame that makes up the lining unit, so the water supply and drainage pipes that are exposed in the existing toilet space and give a cluttered impression are not visible, making the toilet space neat and compact, improving the design.

[0013] In addition, a second aspect of the present invention is a toilet unit characterized in that one core frame is formed into an L-shaped frame at a corner of the toilet space, the rear side of the L-shaped frame is formed along the rear wall of the toilet body installed in the toilet space, and the outer side of the L-shaped frame is formed along the side wall of the toilet body installed.

[0014] According to this toilet unit, since one core frame is disposed at a corner in the toilet space, even if a side frame is connected to the front of one core frame along the lateral wall, the water supply pipe from the water supply source provided on the rear wall is not exposed in the toilet space, providing a toilet space with a neat impression. Also, since one core frame is configured to be erected at a corner in the toilet space, the one core frame is fixed to the wall surface perpendicular to the rear wall surface and the lateral wall surface that constitute the toilet space, and the entire lining unit can be firmly fixed to the wall surface of the toilet space.

[0015] A third aspect of the present invention is a toilet unit characterized in that a portion of each opening and closing hinge portion of the toilet seat and / or toilet lid of the toilet body is stored in the gate-shaped inner space of the gate-shaped case.

[0016] With this toilet unit, by partially storing the opening and closing hinge parts of the toilet seat and toilet lid of the toilet body in the gate-shaped inner space of the gate-shaped case, part of the toilet body is stored in the gate-shaped inner space, allowing the space within the toilet to be utilized as widely as possible. In the case of a flush tank-type toilet, where the water tank is located at the rear of the toilet body, the flush tank is located in the gate-shaped inner space together with part of the toilet body, allowing for a larger toilet space. Also, the gate-shaped case only needs to be thick enough to accommodate the water supply and drainage pipes, so the thickness of the gate-shaped case can be made thinner.

[0017] A fourth aspect of the present invention is a toilet unit characterized in that a rear half of a toilet body is stored in the gate-shaped inner space of a gate-shaped case.

[0018] According to this toilet unit, the rear half of the toilet body is stored in the gate-shaped inner space of the gate-shaped case, thereby providing a toilet space with an even neater appearance.

[0019] A fifth aspect of the present invention is a toilet unit characterized in that a backrest mat is provided in the approximate center of the upper frame of the gate-shaped case so as to be usable while seated on the toilet seat.

[0020] With this toilet unit, by placing a backrest mat on the upper frame erected between the left and right core frames, there is no need to reinforce the walls that form the toilet space, and the installation work period for the gate-shaped case can be shortened. Effect of the Invention

[0021] According to the present invention, it is possible to install the toilet regardless of the shape of the existing toilet, the installation work can be carried out efficiently, and furthermore, the toilet space can be made neat and compact. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] The gist of this invention is that in a toilet unit consisting of a seated toilet body installed in the space within the toilet and a gate-shaped case that straddles the seated toilet body and stores the water supply and drainage pipes of the water supply and drainage equipment in a concealed manner, the gate-shaped case is configured in a gate shape with one core frame erected at the corner of a wall in the toilet space and the other core frame erected with the seated toilet body sandwiched between them and an upper frame connecting the tops of each core frame, with the toilet body straddled by each frame and the water supply and drainage pipes of the water supply and drainage equipment stored within each frame and hidden. Another feature is that one of the core frames is formed into an L-shaped frame at a corner of the toilet space, with the rear side of the L-shaped frame formed along the rear wall of the toilet body installed in the toilet space, and the outer side of the L-shaped frame formed along the side wall of the toilet body installed. Another feature of the present invention is that a part of each opening and closing hinge part of the toilet seat and / or the toilet lid of the toilet body is housed in the gate-shaped inner space of the gate-shaped case. Another feature is that the rear half of the toilet body is stored in the gate-shaped inner space of the gate-shaped case. The toilet is also characterized in that a backrest mat is disposed in the approximate center of the upper frame of the gate-shaped case so as to be usable while seated on the toilet seat.

[0024] An embodiment of the present invention will be described in detail with reference to the drawings. In describing this embodiment, the terms "upper", "lower", "front", "rear", "left side" and "right side" refer to the directions when the toilet bowl in FIG. 2 is viewed from the front.

[0025] The lining unit 100 as a gate-shaped case constituting the toilet unit according to the present invention has a generally gate-shaped case structure that is provided on the floor surface FL in the toilet space so as to contact either the left or right side wall surface WS and the rear wall surface WB, and is formed with a hollow interior, as shown in Fig. 1. In this embodiment, the right side wall surface in the toilet space is taken as the side wall surface WS, and the lining unit 100 is disposed so as to contact this right side wall surface.

[0026] The lining unit 100, which is a gate-shaped case in this embodiment, has an upper frame 3 provided above the floor surface FL in a parallel (horizontal) relationship to the floor surface FL, and left and right core frames 1, 2 provided in front of the rear wall surface WB in a parallel (vertical) relationship to the rear wall surface WB. The core frames 1, 2 and the upper frame 3 are connected to form right angles at the corners of the left and right upper ends of the lining unit 100, and are provided facing the rear wall surface WB and the lateral wall surface WS.

[0027] The lining unit 100 is installed so as to straddle the toilet body 40 of the toilet unit 4. That is, in a plan view, the toilet body 40 is arranged so that a part (rear part) of the toilet body 40 overlaps with the upper frame 3 constituting the lining unit 100, as shown in FIG. 4. Also, the toilet body 40 is arranged in the toilet space close to the other core frame 2 separated from the lateral wall surface WS. That is, as shown in FIG. 1 and FIG. 2, the toilet body 40 is arranged on the floor surface FL shifted to the left side from the approximate center in the left-right direction of the upper frame 3. By arranging the toilet body 40 in this way, the water supply pipe and power line connected to the rear side of the toilet body 40 are shielded by the other core frame 2 and are difficult to see from the user of the multipurpose toilet in which the lining unit 100 of this embodiment is installed, and a multipurpose toilet space with a neat impression can be provided.

[0028] The lining unit 100, which is a gate-shaped case, has one core frame 1 erected at a corner of a wall in the toilet interior space, the other core frame 2 erected from the first core frame 1 with the toilet body 40 in between, and an upper frame 3 erected between the tops of both core frames 1, 2.

[0029] As shown in Fig. 3, one core frame 1 has left and right supports 10, 11 erected on the floor surface, a decorative panel upper support 12 installed on the front upper ends of the left and right supports 10, 11, a decorative panel lower support 13 installed on the front lower ends of the left and right supports 10, 11, and a locking plate 14 installed on the rear upper ends of the left and right supports 10, 11. The left and right supports 10, 11 are configured to have approximately the same shape.

[0030] The support 10 has a vertical portion 10a standing on the floor surface and a horizontal portion 10b extending rearward from the upper end of the vertical portion 10a. On the other hand, the core frame 1 is configured as a generally inverted "L" shape by the vertical portion 10a and the horizontal portion 10b.

[0031] The vertical portion 10a and horizontal portion 10b constituting one core frame 1 are both made of straight steel material with a U-shaped cross section. Each of these portions has plate-shaped main body plate portions 10a1, 10b1 forming the main body portion, and plate-shaped side edge plate portions 10a2, 10a2, 10b2, 10b2 bent at right angles from the left and right edges of the main body plate portions 10a1, 10b1. The side edge plate portions 10a2, 10b2 are strip-shaped portions that run along the extension direction of the vertical portion 10a and the horizontal portion 10b.

[0032] In detail, the horizontal portion 10b has a horizontal main body plate portion 10b1 whose thickness direction is the up-down direction. The horizontal portion 10b has side edge plate portions 10b2, 10b2 provided on both the left and right sides of the main body plate portion 10b1. The vertical portion 10a has a vertical main body plate portion 10a1 whose thickness direction is the front-rear direction, and left and right side edge plate portions 10a2, 10a2.

[0033] In one core frame 1 having these plate portions, the side edge plate portion 10b2 of the horizontal portion 10b and the side edge plate portion 10a2 of the vertical portion 10a form a common surface portion. That is, these side edge plate portions 10a2, 10b2 form a continuous side plate portion that follows the approximately inverted "L" shaped outer shape of the one core frame 1. In addition, the main body plate portion 10b1 of the horizontal portion 10b becomes the upper surface portion of the one core frame 1, and the main body plate portion 10a1 of the vertical portion 10a becomes the front surface portion of the one core frame 1.

[0034] One core frame 1 has a support 10 erected on a floor surface FL along a lateral wall surface WS, and a support 11 erected on the floor surface FL at a fixed distance from the support 10 in a direction (left-right direction) away from the lateral wall surface WS. The support 11 is formed in substantially the same shape as the one support 10. A decorative board upper support 12 is installed on the front upper end of each main body plate portion 10a1, 11a1 of the one support 10 and the other support 11, a decorative board lower support 13 is installed on the front lower end of each main body plate portion 10a1, 11a1, and a locking plate 14 is installed on the rear end of each main body plate portion 10b1, 11b1.

[0035] As shown in Figure 3, the decorative panel upper support 12 has a vertical portion 12a that is parallel to the rear wall surface WB, a horizontal portion 12b that is bent rearward at a right angle from the upper end of the vertical portion 12a and is parallel to the floor surface FL, and a decorative panel support portion 12c that is approximately L-shaped and is bent forward at a right angle from the lower end of the vertical portion 12a and has its tip bent further upward at a right angle.

[0036] The horizontal portion 12b has a rectangular plate-like outer shape and is fixed to the main plate portions 10b1 and 11b1 of the horizontal portions 10b and 11b by fasteners such as bolts. The vertical portion 12a has a rectangular plate-like outer shape like the horizontal portion 12b. The vertical portion 12a is fixed to the main plate portions 10a1 and 11a1 of the vertical portions 10a and 11a by fasteners such as bolts. In addition, a decorative plate support portion 12c is protruding forward from the lower end of the vertical portion 12a. The decorative plate V1, which is the design surface of the lining unit 100, is hooked to this decorative plate support portion 12c. The decorative plate V1 has an upper hook portion protruding backward from the back surface near the upper end. The upper hook portion is configured in a substantially "L" shape by a plate-like horizontal portion extending parallel to the floor surface FL from the back surface of the decorative plate and a vertical portion bent at a right angle downward from the tip of the horizontal portion. The upper hook portion is hooked and fixed to the decorative board support portion 12c at its vertical portion.

[0037] The decorative panel lower support 13 has a vertical portion 13a parallel to the rear wall surface WB, a horizontal portion 13b bent at a right angle backward from the lower end of vertical portion 13a and disposed on the floor surface FL, and a decorative panel support portion 13c that is approximately L-shaped and bent at a right angle forward from the upper end of vertical portion 13a, with its tip bent further upward at a right angle.

[0038] The horizontal portion 13b has a rectangular plate-like outer shape and is fixed to the floor surface FL by fasteners such as bolts. The vertical portion 13a has a rectangular plate-like outer shape like the horizontal portion 13b. The vertical portion 13a is fixed to the main plate portions 10a1, 11a1 of the vertical portions 10a, 11a of the supports 10, 11 by fasteners such as bolts. In addition, a decorative board support portion 13c, which is approximately "L" shaped in side view, is extended forward from the upper end of the vertical portion 13a. The decorative board V1, which is the design surface of the lining unit 100, is hung on the decorative board support portion 13c of the decorative board lower support 13 configured in this manner. The decorative board V1 has a lower hook portion protruding from the back surface near the lower end. The lower hook portion is configured in an approximately "L" shape by a plate-like horizontal portion extending parallel to the floor surface FL from the back surface of the decorative board and a vertical portion bent at a right angle downward from the tip of the horizontal portion. The lower hook portion is hooked and fixed to the decorative board support portion 12c at its vertical portion.

[0039] In this way, by fastening the decorative board V1 to the upper decorative board support 12 and the lower decorative board support 13, a hollow storage space S1 is formed surrounded by the decorative board V1, the side wall surface WS, the rear wall surface WB, and the top plate SB disposed on the upper surfaces of the horizontal parts 10b, 11b of the left and right supports 10, 11. By storing the piping T, etc. in this storage space S1, the piping T is not visible to users of the toilet space, giving the impression of a neat and tidy space.

[0040] As shown in Fig. 3, the locking plate 14 is a member having a substantially "L"-shaped cross section, which has a horizontal portion 14a parallel to the floor surface FL and a vertical portion 14b bent at a right angle from the rear end of the horizontal portion 14a and extended downward. The horizontal portion 14a has a rectangular plate-like outer shape and is fixed to the main plate portions 10b1 and 11b1 of the horizontal portions 10b and 11b with fasteners such as bolts. The vertical portion 14b has a rectangular plate-like outer shape like the horizontal portion 14a and is fixed to the rear wall WB with fasteners such as bolts.

[0041] In this way, the locking plate 14 can fix each of the supports 10, 11 to the rear wall surface WB by fastening the horizontal portion 14a to each of the supports 10, 11 while fixing the vertical portion 14b to the rear wall surface WB.

[0042] The side edge plate portion 10a2 has a fixing hole through which a fastener passes. In this embodiment, the hole is provided at two locations, near the upper end of the side edge plate portion 10a2 in the vertical portion 10a and near the approximately center in the up-down direction. The fastener passes through the hole and is screwed into the lateral wall surface WS to fix one of the core frames 1.

[0043] Further, a fixing hole for passing a fastener therethrough is formed in the locking plate 14. In this embodiment, the hole is provided in the vertical portion 14b, and the fastener passes through the hole and is screwed into the rear side wall surface WB to fix one of the core frames 1.

[0044] In this way, by fixing the core frame 1 to the lateral wall surface WS and the rear wall surface WB, the load generated on the left and right supports 10, 11 is distributed to the lateral wall surface WS and the rear wall surface WB, so that the lining unit 100 can be installed and fixed without reinforcing each wall surface. The fixing structure of one core frame 1 may be a structure in which it is indirectly fixed to the rear wall WB or the lateral wall WS via another member.

[0045] The other core frame 2 is erected along the rear wall surface WB from one core frame 1 constructed in this manner, at a position sandwiching the toilet body 40 of the toilet unit 4. In other words, the other core frame 2 is erected on the floor surface FL at a position spaced a certain distance from the lateral wall surface WS of the multipurpose toilet space.

[0046] The other core frame 2 is constructed substantially identically to the one core frame 1, and therefore the same components will be denoted by 20s instead of the 10s used in the description of the one core frame 1. For example, the support 10 is indicated by support 20, and the support 11 is indicated by support 21. The other core frame 2 is erected on the floor surface FL so that the horizontal parts 20b, 21b of the left and right supports 20, 21 are fixed to the rear wall surface WB. Handrail supports 25, 26 are provided on the main plate parts 20a1, 21a1 of the vertical parts 20a, 21a constituting the other core frame 2 near the upper end and approximately near the center in the vertical direction.

[0047] The handrail support 25 has a rectangular main body plate portion 25a installed near the upper ends of the left and right supports 20, 21, and similarly rectangular side edge plate portions 25b, 25b bent at right angles from the left and right side edges of the main body plate portion 25a and extended rearward.

[0048] 3, the main body plate portion 25a has upper and lower horizontal portions 25a1, 25a2 that are bent at right angles at the upper and lower ends and extended rearward, and has a generally U-shaped cross section. The rear ends of the upper and lower horizontal portions 25a1, 25a2 of the main body plate portion 25a abut against the respective vertical portions 20a, 21a.

[0049] The main body plate portion 25a has side edge plate portions 25b, 25b extending from the left and right side edges. The side edge plate portions 25b, 25b are fixed by fasteners while in contact with the side plate portion 20a2 and the side plate portion 21a2. By configuring the main body plate portion 25a and the side edge plate portion 25b in this manner, the handrail support body 25 can be fixed in contact with the vertical portions 20a, 21a of the supports 20, 21. In addition, the protruding length of the handrail H can be changed simply by changing the length of the upper and lower horizontal portions 25a1, 25a2 of the main body plate portion 25a attached to the left and right supports 20, 21.

[0050] A handrail support 26 is disposed below the handrail support 25. The handrail support 26 is a member installed between the left and right supports 20, 21 approximately in the vicinity of the center in the vertical direction, and has a plate-shaped main body plate portion 26a and plate-shaped side edge plate portions 26b, 26b that are bent rearward at right angles from the left and right side edges of the main body plate portion 26a and extended therefrom.

[0051] The main body plate portion 26a is a plate material having a generally U-shaped cross section with the upper and lower ends bent rearward at right angles, and has a fixing hole for fixing the handrail H on the front portion. The rear ends of the upper and lower horizontal portions 26a1, 26a2 of the main body plate portion 26a abut against the main body plate portions 20a1, 21a1 of the vertical portions 20a, 21a. This allows the protruding length of the handrail H to be changed simply by changing the length of the upper and lower horizontal portions 26a1, 26a2 of the main body plate portion 26a attached to the left and right supports 20, 21. In order to maintain the parallel state of the handrail H, the upper and lower horizontal portions 25a1, 25a2 of the main body plate portion 25a and the upper and lower horizontal portions 26a1, 26a2 of the main body plate portion 26a are made to be approximately the same length.

[0052] In addition, because the handrail H is fixed to the supports 20, 21 via the upper and lower handrail supports 25, 26, the load generated on the handrail H is distributed to the upper frame 3 and the rear side wall WB connected to the support 21, reducing as much as possible the risk of localized loads being generated on each frame constituting the lining unit 100. In other words, the load generated on the handrail H is transmitted to the upper frame 3 via the left and right supports 20, 21 and the support 21, and then transmitted to the rear side wall WB, respectively, thereby dispersing the load and reducing as much as possible the risk of localized loads being generated, and reducing as much as possible the risk of the core frame 2 being deformed.

[0053] The other core frame 2 configured in this manner has a decorative board V2 disposed in front of the left and right supports 20, 21. The decorative board V2 is supported and fixed to the decorative board support portion 22c of the decorative board upper support portion 22 at a portion near its upper end, and is supported and fixed to the decorative board support portion 23c of the decorative board lower support portion 23 at a portion near its lower end.

[0054] In addition, a plurality of brackets are protruding from the side plate portion 21a2 and the side plate portion 21b2 of the support body 21. The brackets are substantially "L" shaped members having a horizontal portion protruding horizontally to the left from the side plate portion 21a2 and the side plate portion 21b2 and a vertical portion bent at a right angle upward from the tip of the horizontal portion and extending upward. A decorative plate V3 that shields the left side surface of the core frame 2 is engaged with the brackets. The decorative plate V3 is a rectangular plate member, and the short side is configured to be substantially the same length as the horizontal portion 21b of the core frame 2, and the long side is configured to be substantially the same length as the vertical portion 21a of the core frame 2. As a result, the left side surface of the core frame 2 is blocked by the decorative plate V3, and the inside cannot be seen.

[0055] In this way, the core frame 2 forms a storage space S2 between the decorative panels V2, V3, the floor surface FL, and the rear wall surface WB. The storage space S2 can store the piping T, such as water supply pipes and power lines, that are necessary to operate the equipment installed in the multi-purpose toilet space. As a result, the piping T is stored in the storage space S2, giving a neat and tidy impression to users of the multi-purpose toilet space.

[0056] An upper frame 3 is installed between the upper ends of the core frames 1, 2. The upper frame 3 has a support 30 arranged adjacent to the support 11 of one core frame 1, a support 31 arranged adjacent to the support 20 of the other core frame 2, a decorative board support frame 32 installed on the upper front ends of the left and right supports 30, 31, a reinforcing plate 33 installed on the lower front ends of the left and right supports 30, 31, and a locking plate 34 installed on the rear ends of the left and right supports 30, 31.

[0057] The supports 30, 31 have the same structure as the supports 10, 11 or the supports 20, 21 constituting the core frames 1, 2, and have a vertical section 30a perpendicular to the floor surface FL and a horizontal section 30b bent at a right angle from the upper end of the vertical section 30a and extending rearward. A decorative board support frame 32 is installed at the upper end of the front end of the supports 30, 31, and a reinforcing plate 33 is installed at the lower end. A locking plate 34 is installed at the rear end of the supports 30, 31. The left and right ends of the decorative board support frame 32 and the reinforcing plate 33 are connected by braces 35, 35.

[0058] The decorative board support frame 32 is a member having a generally L-shaped cross section, which has a vertical portion 32a and a horizontal portion 32b that is bent at a right angle rearward from the upper end of the vertical portion 32a.

[0059] The vertical portion 32a is formed to have approximately the same length as the distance between the supports 11 and 20 of the left and right core frames 1 and 2. That is, the vertical portion 32a is configured to have a length such that the left and right ends contact the side ends of the side plate portions 11a2 and 20a2 of the supports 11 and 20, specifically, the left side plate portion 11a2 to the right side plate portion 20a2. This makes it possible to restrict the vertical portion 32a from contacting the side plate portions 11a2 and 20a2 and swinging when the upper frame 3 is assembled to the left and right core frames 1 and 2. In addition, the left and right ends of the vertical portion 32a have holes for inserting fasteners, and are fixed to the supports 30 and 31 by fasteners such as bolts through the holes.

[0060] The horizontal portion 32b is formed to have approximately the same length as the vertical portion 32a, and has holes near the left and right ends. The holes are located approximately in the center in the left-right direction of the horizontal portions 30b, 31b of the supports 30, 31. The horizontal portion 32b is screwed into the horizontal portions 30b, 31b with fasteners such as bolts through the holes.

[0061] The horizontal portion 32b has left and right ends to which locking portions 32c, 32c having approximately the same front-rear length as the horizontal portion 32b extend. The locking portion 32c is a rectangular plate material, and its back side is in contact with the upper surfaces of the horizontal portions 11b, 20b of the left and right core frames 1, 2. The locking portion 32c is fixed to the horizontal portions 11b, 20b with fasteners such as bolts. That is, the decorative board support frame 32 is fixed to the upper surfaces of the horizontal portions 11b, 20b by the locking portions 32c, 32c, and the left and right ends of the horizontal portion 32b are in contact with and fixed to the upper surfaces of the horizontal portions 30b, 31b of the supports 30, 31, so that the support 11 and the support 30, and the support 20 and the support 31 are adjacent to each other, and the upper frame 3 can be installed between the left and right core frames 1, 2. A reinforcing plate 33 is disposed below the decorative board support frame 32.

[0062] The reinforcing plate 33 is disposed between the lower ends of the front faces of the left and right supports 30, 31. The reinforcing plate 33 is a member having an approximately L-shaped cross section, having a vertical portion 33a that is perpendicular to the floor surface FL, and a horizontal portion 33b that is horizontal to the floor surface FL and is bent at a right angle rearward from the lower end of the vertical portion 33a.

[0063] The reinforcing plate 33 is formed to a length that contacts the rear end of the side plate portions 11a2, 20a2 of the supports 11, 20. Specifically, it is formed to a length from the right rear end of the side plate portion 11a2 to the left rear end of the side plate portion 20a2. As a result, when a load is generated on the handrail H, the load applied to the supports 20, 21 can be transmitted to the upper frame 3 not only through the decorative board support frame 32 but also through the reinforcing plate 33, and the risk of the portal frame being distorted is reduced as much as possible by distributing the load generated on the supports 20, 21.

[0064] The decorative board support frame 32 and the reinforcing board 33 thus constructed are connected and fixed near the left and right ends by braces 35, 35, as shown in FIG.

[0065] The braces 35, 35 are generally rectangular plates that are inclined from the left and right ends of the reinforcing plate 33 toward the left and right center of the decorative board support frame 32, and are connected to form a generally V-shape when viewed from the front. By connecting the decorative board support frame 32 and the reinforcing plate 33 with the braces 35, 35 in this way, the rigidity of the upper frame 3 is improved and it is less likely to deform.

[0066] In addition, a locking plate 34 is installed on the rear ends of the supports 30 and 31. The locking plate 34 is a substantially "L" shaped member having a horizontal portion 34a parallel to the floor surface FL and a vertical portion 34b bent downward at a right angle from the rear end of the horizontal portion 34a to be perpendicular to the floor surface FL.

[0067] The locking plate 34 is fixed near both left and right ends of the horizontal portion 34a to the horizontal portions 30b, 31b of the supports 30, 31 and the horizontal portions 11b, 20b of the supports 11, 20 with fasteners such as bolts. The vertical portion 34b has holes drilled near the left and right ends and approximately in the center in the left-right direction, and is fixed to the rear wall WB with fasteners such as bolts through the holes. As a result, the upper frame 3 is fixed to the rear side wall WB with fasteners, reducing as much as possible the risk of the lining unit 100 moving away from the rear side wall WB and swinging.

[0068] The decorative board support frame 32 has decorative board support parts that are generally "L" shaped in side view and protrude forward from both left and right ends and approximately the center in the left-right direction of the vertical part 32a, and the reinforcing board 33 has decorative board support parts that are generally "L" shaped in side view and protrude forward from both left and right ends and approximately the center in the left-right direction of the vertical part 33a. The decorative board V4 has a locking part on the back side that is generally "U" shaped and opens downward in side view. The decorative board V4 is supported and fixed to the front of the upper frame 3 by engaging the locking part with the decorative board support part of the decorative board support frame 32 and the decorative board support part of the reinforcing board 33.

[0069] A top plate SB is placed and fixed on the top surfaces of the left and right core frames 1 and 2 and the upper frame 3. As shown in FIG. 1, the top plate SB is configured to have a length that hides the area from the right end of the support 10 of the core frame 1 to the left end of the support 21 of the core frame 2. In other words, the top plate SB is configured to have a length that prevents the left and right core frames 1 and 2 and the upper frame 3 from being visible from above in a plan view. The top plate SB is fixed to the main plate parts 10b1 and 11b1 of the core frame 1, the main plate parts 20b1 and 21b1 of the core frame 2, and the main plate parts 30b1 and 31b1 of the upper frame 3 with fasteners such as bolts. This allows the top surface of the top plate SB to form a seamless horizontal flat surface, and allows the core frames 1 and 2 and the upper frame 3 to be fixed as an integrated gate-shaped frame.

[0070] In addition, a backrest mat 50 is disposed on the front surface of the upper frame 3. As shown in Figs. 1 and 2, the backrest mat 50 is substantially rectangular in front view and has a concave portion in the substantially central portion. This allows the backrest mat 50 to support the body of the toilet user so that it does not sway while using the toilet. In addition, the backrest mat 50 is fixed to the decorative plate V4 constituting the upper frame 3 with fasteners such as bolts. This allows the load generated when the toilet user uses the backrest mat 50 to be distributed to the core frames 1 and 2 and the rear wall surface WB through the upper frame 3. In other words, since the configuration makes it difficult for the user to apply a local load to the backrest mat 50, when the gate-shaped case is installed in the toilet space, there is no need to reinforce the rear wall surface WB and the side wall surface WS to which the gate-shaped case is supported and fixed, and the installation period of the gate-shaped case can be shortened.

[0071] The upper frame 3 thus constructed has a storage space S3 that is closed so that the water supply pipe, power line, etc. at the downward opening cannot be seen from the outside. The storage space S3 is a downward opening space surrounded by the rear wall WB, the top plate SB, and the decorative plate V4. By making the storage space S3 open downward, the water supply pipe arranged in the storage space S3 can be extended from the storage space S3 to the outside without special construction, which reduces the number of steps and shortens the construction period.

[0072] Below the upper frame 3 configured in this manner, a gate-shaped inner space S of the gate-shaped case formed by the core frames 1, 2 and the upper frame 3 is formed. The gate-shaped inner space S is a space surrounded by the core frame 1 on one side, the core frame 2 on the other side, the upper frame 3, and the floor surface FL, and a toilet unit 4 is disposed inside it.

[0073] The toilet unit 4 is erected on the floor surface FL close to the side wall surface WS and the rear wall surface WB of the multi-purpose toilet space. As shown in Figures 1 and 2, the toilet unit 4 is composed of a toilet body 40, a toilet seat 41 placed and fixed on the upper surface of the toilet body 40, an opening and closing hinge part 42 located at the rear end part of the toilet seat 41, and a toilet tank 43 placed and fixed behind the opening and closing hinge part 42.

[0074] The toilet body 40 is placed and fixed on the floor surface FL, and a tank support part 40a is protruding from the rear part. A toilet seat 41 is placed and fixed on the upper surface of the toilet body 40. The toilet seat 41 has an opening and closing hinge part 42 for rotating the toilet seat 41 at its rear end. The opening and closing hinge part 42 is disposed near the front end part of the tank support part 40a of the toilet body 40. As shown in FIG. 5(a), the opening and closing hinge part 42 is disposed so that a part of it overlaps with the upper frame 3 in a plan view. Also, as shown in FIG. 6(a), the opening and closing hinge part 42 is disposed so that a part of it overlaps with the front end parts of the left and right core frames 1 and 2 in a side view. In other words, the opening and closing hinge part 42 is disposed so that a part of it is stored inside the gate-shaped inner space S. As a result, a part of the toilet body 40 is also stored in the gate-shaped inner space S, reducing the portion of the toilet body 40 protruding into the toilet space, allowing the toilet space to be used as widely as possible.

[0075] The low tank 43 is disposed behind the opening / closing hinge portion 42 disposed in this manner. The low tank 43 is a box body having a substantially rectangular parallelepiped shape, and is a substantially gate-shaped box body in a front view with a rectangular cutout portion cut from the front to the rear of the low tank 43 at the substantially center of the left and right direction of the lower end. The low tank 43 has a connecting portion with a water supply pipe for refilling flushing water on the lower left side. The low tank 43 has the cutout portion placed and fixed on the tank support portion 40a of the toilet body 40. As a result, the lower left and right ends of the low tank 43 are fixed to the toilet body 40 in a floating state, and the water supply pipe can be connected to the connecting portion on the lower left side of the low tank 43 in a state where it is difficult to see from the outside.

[0076] A water supply pipe is provided inside the lining unit 100 to supply flush water to the toilet body 40 to the low tank 43. The water supply pipe protrudes from the rear wall WB located behind the upper frame 3, and is arranged so as not to be seen by users of the multi-purpose toilet space by a decorative panel V3 provided on the front surface of the upper frame 3. The water supply pipe is distributed by a branch into flush water to be supplied to the low tank 43 and flush water to be supplied to the ostomate flushing equipment used by internally disabled people located on the left side of the other core frame 2. The water supply pipe distributed in two directions by the branch is arranged so as not to be seen by users of the multi-purpose toilet space by the decorative panel V3 of the upper frame 3.

[0077] Also, as shown in Fig. 8, a side frame SF may be provided along a lateral wall surface WS in front of the core frame 1 disposed in a corner of the multi-purpose toilet space. The side frame SF is provided with a washing facility for toilet users to wash their hands after using the toilet. When supplying water to the washing facility of the side frame SF, the water can be extended from a water supply pipe protruding from the rear wall surface WB behind the upper frame 3 through the storage space S3 of the upper frame 3 and the storage space S1 of the core frame 1 to the washing facility of the side frame SF without being seen by toilet users.

[0078] The side frame SF does not need to be formed separately from the core frame 1, and the core frame 1 may be extended forward to function as a side frame. Specifically, the horizontal parts 10b, 11b of the supports 10, 11 are extended forward along the lateral side wall surface WS, a decorative plate is attached to the side plate part 11a2 of the vertical part 11a and the side plate part 11b2 of the horizontal part 11b, and a top plate is provided on each of the main plate parts 10b1, 11b1 of the horizontal part 10b and the horizontal part 11b, thereby forming a side frame having a storage space S1 surrounded by the decorative plate and the top plate. Various equipment constituting the side frame can be installed on the decorative plate and the top plate of this side frame. For example, an operation panel for operating a warm water washing toilet seat used by a toilet user after using the toilet, a toilet paper holder, etc. can be installed on the decorative plate, and a washing equipment for hand washing can be installed on the top plate. By integrating the core frame 1 and the side frames in this way, the power supply line to the operation panel and the water supply and drainage pipes to the flushing equipment can be stored in the storage space S1, creating a neat and tidy toilet space. Furthermore, there is no need to prepare a frame to configure the side frames, and the number of parts is reduced, allowing the installation work of the side frames to be carried out efficiently.

[0079] The lining unit 100 of this embodiment, configured as described above, allows each core frame 1, 2 and upper frame 3 to function as installation space for hollow piping, while the front and sides or top surface of each frame are covered with decorative panels V1, V2, V3, V4 and top plate SB, thereby hiding the piping and the like from users, providing a multi-purpose toilet space with a clean impression.

[0080] In addition, by making each core frame 1, 2 and upper frame 3 of the lining unit 100 of this embodiment a gate-shaped frame structure, it can be installed without detaching the water supply pipe of the water supply tank (low tank 43) connected to the existing toilet body 40 and the drain pipe from the toilet body 40, and the installation work of the lining unit 100 can be carried out efficiently.

[0081] In addition, in the lining unit 100 of this embodiment, by making each core frame 1, 2 and upper frame 3 into a gate-shaped frame structure, the low tank 43 of the toilet body 40 and a portion of the toilet seat 41 or the opening and closing hinge portion 42 of the toilet lid can be stored in the gate-shaped inner space S of the gate-shaped frame, allowing the multi-purpose toilet space to be utilized as widely as possible.

[0082] In addition, in the lining unit 100 of this embodiment, by forming an opening on the side of the gate-shaped inner space S in each frame, it is not necessary to process the decorative panel when pulling out piping such as water supply pipes and power lines from the storage spaces S1, S2, and S3 of each frame to the required locations, thereby improving the freedom of piping layout and shortening the construction period. In addition, in the lining unit 100 of this embodiment, an opening is formed on the gate-shaped inner space S side of each frame, so that the piping stored in the storage spaces S1, S2, and S3 of each frame can be inspected without providing an inspection hatch or the like.

[0083] In addition, by arranging the backrest mat 50 so that it is supported by the upper frame 3, it is no longer necessary to reinforce the rear side wall WB, which was previously required, and the construction time required for installing the lining unit 100 can be shortened.

[0084] In this embodiment, the core frames 1, 2 and the upper frame 3 are described as separate frame structures, but the frames may be formed as an integral structure in which they are connected. For example, as shown in FIG. 7, the decorative plate support frame 32 and the locking plate 34 are configured to have a length that can connect the support 10 of the core frame 1 to the support 21 of the core frame 2, and the reinforcing plate 33 is configured to have a length that can connect the support 11 of the core frame 1 to the support 20 of the core frame 2, and a reinforcing part 36 that is approximately triangular in side view is formed to connect the approximately left-right center parts of the decorative plate support frame 32, the locking plate 34, and the reinforcing plate 33, so that each frame can be formed integrally. By integrating the frames that form the lining unit 100, which is a gate-shaped case, in this way, the load is more easily transmitted and local loads are less likely to occur than when the core frames 1, 2 and the upper frame 3 are configured separately, and the strength of the lining unit 100 can be further improved.

[0085] In this embodiment, the top plate SB constituting the top surfaces of the core frames 1, 2 and the upper frame 3 is configured as a single top plate SB, but the top plate SB may be configured as separate pieces on the top surfaces of the core frames 1, 2 and the upper frame 3, respectively, as shown in Fig. 9. This allows the work time required to install the lining unit 100 to be shortened. That is, when the top plate SB of the lining unit 100 is integrated, if the upper ends of the core frames 1 and 2 and the upper frame 3 cannot be installed parallel to the floor surface FL, the installed top plate SB will be inclined, or a part of the top plate SB will be floating from the upper ends of the core frames 1 and 2 and the upper frame 3. In order to solve this, the upper surfaces of the core frames 1 and 2 and the upper frame 3 need to be positioned on the same plane parallel to the floor surface FL, and it takes time to install the lining unit 100. In contrast, according to a configuration in which independent top plates SB1, SB2, and SB3 are provided on the upper surfaces of the core frames 1 and 2 and the upper frame 3, respectively, each frame is configured independently, so that the work of installing each top plate SB1, SB2, and SB3 on the upper surface of each frame can be easily performed. In addition, after installation, each top plate SB1, SB2, and SB3 can be made flush by simply changing the plate thickness of the top plates SB1, SB2, and SB3 placed on the upper surfaces of each frame so that the upper surfaces of the top plates SB1, SB2, and SB3 are flush. In this way, by installing the top plate SB in a flush state with the independent top plates SB1, SB2, and SB3, the installation work can be made more efficient while maintaining the same appearance of the lining unit 100 compared to when the top plate SB is constructed from a single plate body.

[0086] In addition, in this embodiment, a configuration has been described in which the toilet body 40 of the toilet unit 4 is installed on the floor surface FL so that a portion of the opening and closing hinge portion 42 is stored in the gate-shaped inner space S, but the toilet body 40 may also be arranged so that the rear half of the toilet body 40 is stored in the gate-shaped inner space S, as shown in Figures 5(b) and 6(b). By specifying the positional relationship between the toilet body 40 and the gate-shaped inner space S in this manner, the piping T to the water tank (low tank 43) becomes even less visible to toilet users, giving the impression of a neat and tidy toilet space, and by reducing the portion of the toilet body 40 protruding into the toilet space, the space available for use as a toilet space can be further expanded.

[0087] The present invention is not limited to the above-described embodiment, but includes configurations in which the configurations disclosed in the above-described embodiment are mutually substituted or changed in combination, known inventions, and configurations in which the configurations disclosed in the above-described embodiment are mutually substituted, etc. The technical scope of the present invention is not limited to the above-described embodiment, but extends to the matters described in the claims and their equivalents.
