Description

This invention relates to a toilet device that aims to make the toilet room more compact by reducing the forward protrusion of the wall-hung toilet body as much as possible in a public multi-purpose toilet.

Public multi-purpose toilets are becoming larger in floor space due to the need to install baby chairs inside the toilet room. At present, it is practically difficult to increase the floor space of a toilet room in a building, especially in a remodeled building, and as a result, the only way to create an environment in which the toilet room can be used more effectively and widely is to simplify (make compact) the toilet itself and its associated equipment.

Furthermore, there is a trend towards using wall-hung toilets in toilet rooms to reduce the burden of cleaning work and as a measure against infectious diseases. In such wall-hung toilets, a structure to support the toilet needs to be provided behind the toilet, making it even more difficult to expand the usable space in the toilet room. Examples of such wall-hung toilets include those described in Patent Document 1 and Patent Document 2.

Patent Document 1 describes a configuration in which the front and rear ends of a plate-like panel with different sized circular holes on the top and bottom are extended in either the left or right direction to form a roughly U-shaped surface when viewed from above, and the toilet bowl can be supported in a raised position above the floor of the toilet space by fastening the left and right upper ends of the toilet bowl on the rear side of the extended parts of the panel with bolts or the like.

The wall-hung toilet described in Patent Document 2 is configured so that the toilet can be supported in a state where it is raised above the floor of the toilet space by engaging the rear side of the toilet with two bolts on the left and right that protrude forward from beams that make up a box-shaped frame formed in a roughly rectangular parallelepiped shape that is installed on the floor of the toilet room.

Japanese Patent Application Publication No. 09-217409 JP 2016-138418 A

However, the technology disclosed in Patent Document 1 supports the toilet bowl by panels that are erected on the floor of the toilet space independently of each other on the left and right, and therefore if the front-to-back width of the panel is narrowed to reduce the forward protrusion of the wall-hung toilet, the required support strength for supporting the toilet bowl cannot be obtained, and there is a risk of the support panel becoming deformed or damaged.

In addition, in the technology disclosed in Patent Document 2, in order to support the weight load generated by the toilet, a certain level of support strength is maintained by distributing it among multiple beams that make up the box-shaped frame. Therefore, if the front-to-rear length of the beams that make up the box-shaped frame is shortened, the certain level of support strength for supporting the toilet cannot be maintained, and there is a risk that the box-shaped frame will deform and the toilet body will tilt or come into contact with the toilet space floor.

The present invention was made in consideration of these problems, and aims to provide a toilet device that is compact while still providing the support strength to support the toilet bowl.

The toilet device according to the present invention is a toilet device that includes a toilet body and a support structure for fixing the toilet body in a position above the floor surface, and the support structure is formed into a roughly U-shape overall by a front plate for connecting the rear of the toilet body, and a left side plate and a right side plate that protrude rearward from the left and right edges of the front plate.

In a toilet device with this configuration, the support structure that supports the wall-hung toilet is connected to each panel in a roughly U-shape, which improves the rigidity of the front panel in the front-to-rear direction and makes the toilet device's forward-facing configuration more compact.

In another aspect of the toilet device according to the present invention, the support structure is made up of a vertical front panel, vertical left and right side panels, and a flat floor panel with the bottom edges of each panel connected together, forming an overall roughly U-shaped structure on the floor panel.

With a toilet device configured in this way, all of the panels that make up the support structure can be connected to prevent the panels from deforming, thereby improving the rigidity of the support structure.

Another aspect of the toilet device according to the present invention is that the left or right side panel has a vertically long insertion hole through which a drain pipe for draining water from the toilet body can be inserted.

A toilet device with this configuration can accommodate vertical adjustment of the drain pipe in accordance with the drain gradient, which is adjusted appropriately at the installation site of the wall-hung toilet, while maintaining the strength of the support structure.

Another aspect of the toilet device according to the present invention is that reinforcing plates are attached to the front and rear surfaces of the front panel to reinforce the toilet body and support it on the front panel.

A toilet device with this configuration can distribute the load of the toilet body and the load acting on the toilet body over as wide an area of the front panel as possible, reducing localized loads and eliminating the risk of deformation or damage to the support structure.

In another aspect of the toilet device according to the present invention, the toilet body connected to the reinforcing plate is configured to be able to move up and down together with the reinforcing plate relative to the front plate.

In a toilet device configured in this way, the reinforcing plate follows the up and down movement of the toilet body, so the load generated by the toilet body can be distributed over a wide area of the front panel via the reinforcing plate, making it possible to carry out construction without worrying about the load of the toilet body, and also improving maintainability.

The present invention makes it possible to improve the toilet support strength despite the simple structure, and to make the toilet device's forward configuration more compact.

In addition, the left side panel or the right side panel has a vertically long insertion hole for inserting a drain pipe for draining water from the toilet body, and reinforcing plates are attached to the front and rear surfaces of the front panel to reinforce the toilet body to support it on the front panel, and the toilet body connected to the reinforcing plates is configured to be able to move up and down together with the reinforcing plates relative to the front panel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings.
As shown in Figure 1, S indicates a toilet space, i.e., a toilet room, and at a predetermined position within the toilet room S, a support structure 20 for supporting a toilet body 10 at a position raised above the toilet room floor surface S1 is fixed to the floor surface of the toilet room S with bolts.

The toilet body 10 is a wall-hung toilet that is supported at a position above the toilet room floor surface S1, and as shown in Figure 2, it is composed of a toilet bowl portion 11 and a toilet seat portion 12 that is placed on top of it.

As shown in FIG. 3, a water supply pipe 14 that is connected to a water supply tank 30 and a drain pipe 15 for draining waste from the toilet bowl 11 are connected to the rear side of the toilet bowl 11.

The rear side of the toilet body 10 is provided with a mounting surface 16 for supporting and fixing the toilet body 10 at a certain height from the floor surface via a support structure 20.

The support structure 20 for supporting and fixing the thus constructed toilet body 10 above the toilet room floor surface S1 is constructed as follows.

As shown in Figures 4 to 6, the support structure 20 is formed in an approximately U-shape by a front panel 21 for connecting to the rear side of the toilet body 10, a left side panel 22 and a right side panel 23 that protrude in an approximately U-shape from the left and right edge portions of the front panel 21, and a flat floor panel 24 on which the bottom surfaces of each panel are placed and fixed.

The front panel 21 is made of a metal plate that is roughly rectangular when viewed from the front, and a left side panel 22 and a right side panel 23 made of metal are respectively attached to both left and right ends of the front panel 21 and extend rearward. The front panel 21, the left side panel 22, and the right side panel 23 are welded together.

As shown in FIG. 4, the front panel 21 has a vertical hole 21a in the center and vertical slits 21b, 21c near both left and right ends of the upper half, and vertical adjustment holes 21d, 21e are drilled below the left and right vertical slits 21b, 21c. In addition, the front panel 21 has a horizontally elongated front reinforcing flat plate 25 on the front side below the vertical hole 21a.

The front reinforcing plate 25 has fixing screws F inserted from the front to the back near both left and right ends, and the tips of the fixing screws F are screwed into the back reinforcing plate 27. In addition, the front reinforcing plate 25 is overlaid with a horizontally elongated bracket plate 26 that is roughly L-shaped in side view and has a front-rear adjustment screw B protruding from its front surface.

The front-rear adjustment screw B of the horizontal bracket plate 26 is configured so that the front-rear position of the screw head of the front-rear adjustment screw B can be freely adjusted depending on the degree of tightening. This allows the front-rear position of the vicinity of the lower end of the toilet body 10 that abuts against the front-rear adjustment screw B to be adjusted.

As shown in Figure 6, a generally U-shaped rear reinforcing plate 27 with a downward opening is placed on the rear side of the front plate 21. The rear reinforcing plate 27 has locking rods 28 protruding from both upper ends for locking to the mounting surface 16 provided on the rear side of the toilet body 10 (see Figure 4). The locking rods 28 protrude from the front side of the front plate 21 by inserting into vertical slits 21b, 21c drilled on the left and right sides of the front plate 21. This allows the toilet body 10 to freely adjust its height position relative to the toilet room floor surface S1 by adjusting the height position of the locking rods 28 along the vertical slits 21b, 21c.

The left side panel 22 and right side panel 23 welded to the left and right edges of the front panel 21 have circular maintenance holes 22a, 23a drilled in the upper part in a circular shape, and drain pipe holes 22b, 23b drilled in the lower part in a roughly elliptical shape with the major axis extending toward and away from the toilet floor surface S1.

The front panel 21, left panel 22, and right panel 23, which are connected in a roughly U-shape when viewed from above, are placed and fixed on a horizontally elongated floor panel 24, as shown in Figures 7 and 8. The floor panel 24 is fixed to the toilet room floor surface S1 via bolts.

The support structure 20 that supports the toilet body 10 is constructed as described above, and in addition to the toilet body 10, the drain pipe 15 is connected and fixed to the support structure 20.

The drain pipe 15 is supported and fixed to a drain pipe support part 15d, which is approximately U-shaped and has an upper opening, attached to the lower part of the vertically long hole 21a of the front plate 21 as shown in Figures 4 and 8. The drain pipe 15 passes through either the drain pipe hole 22b or 23b provided on the left side plate 22 or the right side plate 23. As shown in Figure 7, the base of the drain pipe 15 extends downward via an elbow pipe 15a, and the middle part extends diagonally upward horizontally via a bellows pipe 15b, with the tip facing the vertically long hole 21a of the front plate 21 and the open end 15c protruding from the vertically long hole 21a of the front plate 21.

As shown in Figures 4 and 5, the drain pipe holes 22b and 23b are formed in a vertically elongated elliptical shape with the major axis extending in the vertical direction, allowing the drain pipe 15 inserted therethrough to move in the vertical direction.

That is, as shown in FIG. 7, the drain pipe 15 is a drain pipe whose open end 15c that joins to the drain hole 10a of the toilet body 10 and its lower part are inclined diagonally downward from the central bellows tube 15b and connected to the elbow tube 15a. The drain pipe 15 is inserted into the oblong shaped part of the drain pipe holes 22b, 23b, so that it can be displaced up and down within the hole via the bellows tube 15b to adjust the joining position with the drain hole 10a of the toilet body 10, making the drainage function smooth and allowing for a natural and reliable drain pipe connection.

The adjustment of the joint position of the drain pipe 15 is performed by adjusting the height of the drainage section by adjusting the height of the drainage section from the toilet room floor surface S1 of the toilet body 10. For example, as shown in Fig. 10 and Fig. 11, when the installation position of the toilet body 10 is set based on the floor finishing material S2, the drain pipe is inserted into the upper part of the elliptical drain pipe holes 22b, 23b, or when the installation position of the toilet body 10 is set based on the concrete slab layer S3 excluding the floor finishing material S2, the drain pipe is inserted into the middle part of the drain pipe holes 22b, 23b. The drain pipe 15 is configured to be reliably joined to the toilet body 10 by adjusting the vertical position of the start part of the drain pipe 15 within the elliptical drain pipe holes 22b, 23b according to the installation position of the toilet body 10.
In the drawing, reference symbol S2 denotes a floor finishing material in the toilet on which the support structure 20 is arranged and fixed, and reference symbol S3 denotes a concrete slab layer S3 formed on the floor finishing material S2.

The open end 15c of the drain pipe 15 is connected to the terminal port of the siphon mechanism formed in the drain hole 10a of the toilet bowl 11.

In this way, the wall-hung toilet body 10 is attached to the front surface of the support structure 20, and the locking rod 28 protruding from the vertical slits 21b, 21c of the support structure 20 to the front surface is locked and connected to the mounting surface 16 provided on the rear surface of the toilet body 10, so that the weight load of the toilet body 10 can be supported by the rear reinforcing plate 27.

When the toilet body 10 is supported by the locking rod 28 and attached to the support structure 20, the lower half of the mounting surface 16 of the toilet body 10 is supported by abutting against the head of the front-rear adjustment screw B protruding from the horizontal bracket plate 26 on the front side of the support structure 20, as shown in Figure 3.

The position of the toilet body 10 above the floor and the connection position with the drain pipe 15 can be adjusted by sliding the locking rod 28, which engages with the mounting surface 16 of the toilet body 10, up and down through the vertical slits 21b and 21c.

The upper left edge 27a and upper right edge 27b of the rear reinforcing plate 27 are bent backwards as shown in FIG. 8, and the upper edge 22c of the left side panel and the upper edge 23c of the right side panel of the support structure 20 are bent sideways, with pin bodies 22d and 23d hanging down from their front ends. The pin bodies 22d and 23d are screwed to the bent pieces of the upper left edge 27a and upper right edge 27b of the rear reinforcing plate 27, suppressing the biased load generated on the rear reinforcing plate 27 by the weight load of the toilet body 10 generated on the locking rod 28 protruding near the top of the rear reinforcing plate 27, and restricting the distortion of the rear reinforcing plate 27 to reinforce the support function of the support structure 20 to support the toilet body 10 as much as possible.

As described above, the toilet body 10 is attached to the support structure 20 by engaging it with the locking rod 28, and the weight load of the toilet body 10 is spread across the entire support structure 20 via the front reinforcing plate 25 and the back reinforcing plate 27.

In other words, if the upper half of the back of the wall-hung toilet body 10 is supported by the locking rod 28, the weight load of the toilet body 10 will apply a tensile stress in the forward direction to the upper part of the support structure 20 via the locking rod 28, and a rearward pressing force will be applied to the lower part of the support structure 20 via the front-to-back adjustment screw B of the horizontal bracket plate 26, which will apply stresses that cancel each other out at the upper and lower positions on the back side of the toilet body 10, balancing the front-to-back stresses at the top and bottom, thereby suppressing the rotational moment generated by the toilet body 10 on the front panel 21. This has the effect of mutually complementing the support function of the toilet body 10 regardless of the simple toilet mounting structure using the support structure 20.

The front reinforcing flat plate 25 is disposed horizontally below the vertically elongated hole 21a on the front side of the support structure 20 and is fixed by inserting fixing screws F near both left and right ends. A horizontal bracket plate 26 is disposed on top of the surface of this front reinforcing flat plate 25 and is integrated with it via a front-to-back adjustment screw B. A front-to-back adjustment screw B protrudes from the horizontal bracket plate 26 to support the weight load on the lower back side of the toilet body 10. By adjusting the amount that the front-to-back adjustment screw B protrudes from the horizontal bracket plate 26, the support load stress derived from the weight load on the lower mounting surface 16 of the toilet body 10 can be adjusted, and the support posture of the toilet body 10 can also be adjusted.

The front reinforcing plate 25 works together with the back reinforcing plate 27 to complement the strength of the entire face plate of the support structure 20, and converts the weight load on the upper and lower parts of the toilet body 10 into a stress balance between upper tensile stress and lower tensile stress at the upper and lower parts of the support structure 20, i.e., it is configured to maintain a balance between forward and backward pulling.

In this embodiment, the drain pipe 15 is connected to the drain hole 10a on the toilet room floor S1 to drain wastewater from the toilet body 10. However, the present invention is not limited to this form of drainage. For example, the drain pipe 15 may not be inserted through either of the drain pipe holes 22b or 23b in order to connect to a horizontal drain pipe installed in the toilet room rear wall S4. In this case, the drain pipe 15 is supported and fixed by the drain pipe support portion 15d and the toilet room rear wall S4.

Finally, the above-mentioned explanations of each embodiment are merely examples of the present invention, and the present invention is not limited to the above-mentioned embodiments. Therefore, even if the embodiment is different from the above-mentioned embodiments, various modifications can be made depending on the design, etc., as long as they do not deviate from the technical concept of the present invention.
