Description

TECHNICAL FIELD The present invention relates to a drain socket that connects an outlet of a toilet bowl body and a drain opening provided on a floor surface.

In conventional Western-style toilet devices, when installing the toilet bowl so that the outflow port of the toilet bowl body (its trap) and the drain hole opened on the floor are spaced horizontally, the distance between them must be taken into consideration. Therefore, a drainage socket is used (for example, see Patent Document 1).

The flange portion of this type of drain socket, which is provided so as to protrude around the bent portion of the drain port connection portion, has a planar outer shape that is approximately circular. For example, the same applies to Patent Document 1, and among the flange parts, the side flanges located on both sides of the bent part and the front flange located in front of the bent part have the same protrusion dimension from the bent part. There is. Note that the side flange is provided with a hole for fixing a screw, and the front side of the bent portion is not provided with a hole for fixing a screw.

The reason why the front flange of the flange part is made to protrude in the same way as the side flanges is that it is separate from the main body of the drain socket, which is attached directly to the drain outlet, even though there are no holes for fixing screws. This is to ensure that the floor flange with the body insert is covered. Furthermore, in consideration of such a double structure, it is possible to provide screw fixing holes even in the largely protruding front flange. Incidentally, if such a floor flange is provided, it is possible to absorb the misalignment between the outlet on the side of the bent part and the drain on the floor surface, but the front flange needs to protrude largely for this purpose as well.

JP2014-181441A

By the way, when using the above-mentioned drain socket, it is naturally necessary to hide the connecting part between the drain socket of the drain socket and the drain outlet with the peripheral wall of the toilet main body. Therefore, the toilet main body must be installed so that the front flange of the flange portion is also covered by the peripheral wall. In other words, if the degree of protrusion of the front flange is large, the toilet main body must be installed so that the front end of the peripheral wall is located in front of the tip of the front flange.

In other words, the larger the protrusion of the front flange, the more the toilet must be installed at a greater distance from the rear wall of the toilet room, and the conditions and restrictions on the installation position of the toilet become more severe, making it difficult to renovate. There is also a possibility that it will not be possible to respond.

The present invention was proposed in consideration of such circumstances, and its purpose is to provide a drain socket that can alleviate the conditions and restrictions on the installation position of the toilet bowl body.

In order to achieve the above object, the drain socket of the present invention is a drain socket that connects an outlet of a toilet main body and a drain opened on a floor surface, and includes a toilet connection part connected to the outlet. and a drain port connection portion connected to the drain port, and a horizontal piping portion connecting the toilet connection portion and the drain port connection portion, the drain port connection portion being connected to the end of the horizontal piping portion. a bent portion arranged to extend from the bent portion; a drain insertion portion attached to the drain port extending in a cylindrical shape so that the inside communicates with the bent portion; the bent portion; the drain insertion portion; a flange portion installed on the floor surface that protrudes in the circumferential direction at an outer boundary between a side flange having a screw fixing hole for connection to the floor surface with a screw, and a front flange located on the opposite side of the horizontal piping section, and a A plurality of vertical ribs are provided in the corner along the circumferential direction, one of the vertical ribs is provided on the front flange along the extending direction of the horizontal piping section, and the front flange The vertical rib provided on the side flange is characterized in that it extends to the front of the front end edge of the side flange.

Since the drain socket of the present invention has the above-described configuration, the conditions and restrictions regarding the installation position of the toilet bowl body can be relaxed.

FIG. 2 is an explanatory diagram of a drainage socket according to an embodiment of the present invention. (a) is a longitudinal cross-sectional view of the drain socket, (b) is a plan view of the drain port connection portion of the drain socket, and (c) is a perspective view thereof. FIG. 3 is a longitudinal cross-sectional view showing how a drain socket is installed in a Western-style toilet device. It is a figure for demonstrating the front end position of this drainage socket, and corresponds to the partial vertical cross section of Fig.1 (a).

Embodiments of the present invention will be described below with reference to the accompanying drawings. First, the general basic configuration of the main drainage socket 20 will be described. In addition, below, directions, such as front-back, top-down, etc., will be defined and explained based on the toilet device 1 to which the drain socket 20 is attached.

As shown in FIGS. 1 and 2, the drain socket 20 connects the outlet 13 of the toilet main body 10 and the drain 7 provided in the floor surface 5. It includes a toilet connection part 21 connected to the outflow port 13, a drain connection part 23 connected to the drain port 7, and a horizontal piping part 22 connecting the toilet connection part 21 and the drain connection part 23. .

The drain connection portion 23 includes a bent portion 24, a drain insertion portion 25, and a flange portion 26. The bent part 24 is disposed to extend from the end of the horizontal piping part 22, and the drain insertion part 25 is a part that is inserted into and attached to the drain 7, and is arranged so that the inside thereof communicates with the bent part 24. It extends into a cylindrical shape. The outer shape of the drain insertion portion 25 is tapered downward by changing the thickness of the pipe. In addition, the flange portion 26 is a portion installed on the floor surface 5, as shown in FIGS. It stands out.

The flange portion 26 includes side flanges 26a having screw fixing holes 26aa located on both sides of the bent portion 24 in a direction perpendicular to the extending direction of the horizontal piping portion 22, and a side flange 26a located on the opposite side from the horizontal piping portion 22. The front flange 26b is provided with at least a front flange 26b. The degree of protrusion of the front flange 26b is smaller than the degree of protrusion of the side flanges 26a.

Further, the toilet device 1 to which the drain socket 20 is attached includes, as shown in FIG. 2, the toilet main body 10 and a peripheral wall 15 surrounding the toilet main body 10. The toilet main body 10 includes a bowl 11 shaped like a mortar with a narrowed bottom side, a trap 12 connected to an outlet 11a on the bottom side of the bowl 11, a toilet seat (not shown), and a toilet lid (not shown). We are prepared.

This trap 12 is a mechanically operated type, and has a cylindrical shape so that it can be switched between the water sealing position (upper position) and the draining position (lower position), as shown by the two-dot chain arrow in Fig. 2. It has a bellows structure. This trap 12 is arranged inside a trap case 14, and the waste water discharged from the outlet 12a of the trap 12 is discharged from the lower end opening of the trap case 14 (outlet 13 of the toilet main body 10). There is. This outlet 13 has a cylindrical shape and is connected to the drain inlet portion 21a of the drain socket 20.

A peripheral wall 15 of the toilet main body 10 is arranged around the bowl 11 and the trap 12 so as to hide them.

Further, this peripheral wall 15 is arranged so as to also surround the drain port 7. This drain port 7 is located in front of the outflow port 13 of the toilet main body 10 and below the front part of the bowl 11. A drain insertion portion 25 of a drain connection portion 23 of the drain socket 20 is connected to the drain port 7. Therefore, the drain socket 20 arranged to connect the outlet 13 of the toilet main body 10 and the drain port 7 is also hidden by the peripheral wall 15.

The toilet device 1 in which this drain socket 20 can be installed is not limited to the one having the mechanically operated trap 12 shown in FIG. 2, but can also be applied to a toilet device having a fixed trap. At least, such a drain socket 20 can be used as long as the drain port 7 provided on the floor surface 5 and the outlet port 13 of the toilet main body 10 are spaced apart in the front-rear direction.

Next, the detailed structure of the drain socket 20 and the relationship between the drain socket 20 and the toilet device 1 will be explained in detail based on FIGS. 1 to 3.

As described above, the drain socket 20 includes the toilet bowl connection part 21, the horizontal piping part 22, and the drain port connection part 23, but in this embodiment, the partitions of these parts are different from each other. It is composed of three separable members. Specifically, the drain socket 20 consists of three members: a first component 31 , a second component 32 , and an adjustment connector 33 .

As shown in FIG. 1(a), the first component 31 includes a toilet connection portion 21 having a drainage inlet portion 21a, and a cylindrical portion 31a of a portion of the horizontal piping portion 22 on the side of the toilet connection portion 21. It is an integrated member. Note that an installation base portion 31c for stably installing the first component 31 on the floor surface 5 is integrally formed below the drainage entrance portion 21a of the first component 31.

The second component 32 is a member corresponding to the drain port connection portion 23 connected to the horizontal piping portion 22 (see FIGS. 1(b) and (c)), and therefore, the toilet side has a drain port connection A toilet side opening 32a is provided which has a larger diameter than the main body cylindrical portion of the portion 23. The lower part of the outer surface of the toilet side opening 32a is formed thick for height adjustment.

Further, the adjustment connector 33 connects the adjustment connector 33 itself between the first component 31 and the second component 32, so that the cylindrical portion 31a of the first component 31 and the adjustment connector 33 This is a cylindrical member for constructing the horizontal piping section 22. Note that it is desirable that the inner bottom surface of the horizontal piping section 22 is provided with a water gradient for drainage.

This adjustment connector 33 has a large diameter portion 33a and a small diameter portion 33b, and is connected such that the large diameter portion 33a fits externally into the drainage side opening 31b of the cylindrical portion 31a of the first component 31. be done. Further, the small diameter portion 33b is connected to the toilet bowl side opening 32a of the second component 32 so as to fit therein.

Since the drain socket 20 is a member that connects the position of the trap 12 in the draining posture (the position of the drain entrance portion 21a of the toilet connection portion 21) and the drain port 7 in the front-rear direction, the total length of the drain socket 20 is as follows. It is necessary to approximately match the distance between the drainage posture position and the drainage port 7 position. In order to obtain such a length, the length of the small diameter portion 33b can be adjusted by cutting. Note that the drain socket 20 may have a configuration in which such an adjustment connector 33 is not used. For example, it may connect two materials (for example, the first component 31 and the second component 32), or it may connect four materials (for example, the first component 31 and the second component 32 and two adjustable connections). 33).

The drain connection portion 23 to which the second component 32 corresponds includes a toilet side opening 32a, a bent portion 24, a drain insertion portion 25, and a flange portion 26. The interior communicates from the toilet side opening 32a to the drain insertion part 25 via the bent part 24.

Insert and attach this drain outlet insertion part 25 to the drain outlet 7, and align the drain inlet part 21a of the rear toilet connection part 21 with the position of the outlet 13 of the toilet main body 10 (lower end opening of the trap case 14). By disposing the drain socket 20 in the appropriate position (see FIG. 1(a) and FIG. 2). With the drain socket 20 properly installed in this manner, the back surface of the flange portion 26 comes into contact with the floor surface 5.

As shown in FIG. 1(b), the flange portion 26 has two side flanges 26a located on both sides of the bent portion 24, that is, on both sides in a direction perpendicular to the longitudinal direction (drainage flow direction) of the horizontal piping portion 22. , and a front flange 26b located on the front side of the bent portion 24. Note that the rear part of the flange portion 26 corresponds to the lower part of the outer surface of the toilet side opening 32a.

As shown in FIG. 1(b), the side flanges 26a have a curved or polygonal outer shape and protrude like wings on both sides of the bent portion 24 in a plan view. Each of the side flanges 26a is provided with two screw fixing holes 26aa for connecting to the floor surface 5 with screws, which are lined up one after the other so as to roughly follow the shape of the outer edge.

On the other hand, the front flange 26b protrudes so as to have a substantially arcuate outer shape. The arc is arranged such that both ends thereof are located inward of the outer edge of the side flange 26a (in the direction in which both outer edges approach) and are located at the obtuse-angled bent portion 26ba with the front edge 26ab of the side flange 26a. has been done.

In other words, the front flange 26b has an imaginary curved line 27 (2 in FIG. 1(b)) that connects the front ends of the outer edges of the side flanges 26a forward without bending to draw an arc concentric with the front flange 26b. It has a cutout-like shape so that it is placed further back than the dotted chain line). In other words, the front flange 26b is not formed so that the portion of the side flange 26a where the two screw fixing holes 26aa are provided extends forward, and the front flange 26b is also provided with holes for fixing with screws. Not yet.

By making the front flange 26b into such a shape, the dimension A from the center X of the drain port 7 (see FIG. 1(b)) to the outer edge is the same as the dimension A from the center X of the drain port 7 to the outer edge of the side flange 26a. B (see FIG. 1(b)). In other words, the front end position C where the center line of the drain socket 20 intersects with the arcuate outer edge of the front flange 26b in plan view is located further back than the front end position D where the center line intersects with the virtual curved line 27. (See Figure 1(b)).

FIG. 3 is a schematic vertical cross-sectional view comparing the front end position C (the main drain socket 20) and the front end position D (the drain socket 200 corresponding to the front end position D). The peripheral wall 15 of the toilet device 1 needs to be installed so that the lower end of its front end portion 15a is located forward of the front end positions C and D. Therefore, if the distance between the front end position C, the front end position D, and the front end part 15a of the peripheral wall 15 is the same, the front end part 15a in the case of the front end position C is larger than the front end part 15a in the case of the front end position D. It will also be on the back side.

In other words, by making the degree of forward protrusion of the front flange 26b smaller than the degree of protrusion of the side flanges 26a, as shown in FIG. can be approached. In other words, by forming the flange portion 26 of the drain port connection portion 23 of the drain socket 20 into the shape as shown in FIG. This leads to an increase in the degree of freedom in installation location.

Further, the back surface of the flange portion 26 (the surface on the drain port insertion portion 25 side) is substantially flat except for the screw fixing holes 26aa provided in the side flange 26a. Therefore, if the drain socket 20 is properly arranged, substantially the entire flange portion 26 will come into close contact with the floor surface 5. Therefore, stable installation of the drain socket 20 can be realized.

Furthermore, since the drain insertion part 25 is fitted into the drain port 7 and the flange part 26 is in close contact with the floor surface 5, it is possible to prevent the drain connection part 23 of the drain socket 20 from shifting or tilting. , leakage of wastewater can also be prevented.

Further, since the drain insertion portion 25 is integrally formed with the drain connection portion 23 as a part of the drain socket 20, there is no need for a separate floor flange used in conventional drain socket installation. Therefore, it is necessary to form the drain port insertion portion 25 so that there is no dimensional error with respect to the drain port 7. However, in the present embodiment, the drain port insertion portion 25 has a tapered shape that tapers downward, so that it can be firmly attached to the drain port 7 even if there is some error.

Since the main drainage socket 20 has such a structure, there is no problem even if the front flange 26b of the flange portion 26 is not fixed with screws. In other words, by making the degree of protrusion of the front flange 26b smaller than the degree of protrusion of the side flanges 26a, there is no problem with the installation strength of the drain socket 20.

In the embodiment described above, the shape of the front flange 26b of the flange portion 26 is an arc shape, but other shapes may be used as long as the degree of protrusion is small, that is, the front end position C (FIG. 1( Various shapes are permissible, provided that (see b)) is as far back as possible. For example, the front flange 26b may have a shape in which the two bent portions 26ba in FIG. 1(b) are connected with a straight line, and the front side thereof is cut off. Furthermore, if the drain port insertion portion 25 is reliably attached to the drain port 7 within its vertical dimension (within the range of the tapered surface) and is fixed, the front flange 26b may not be substantially formed. Good too. That is, the protrusion dimension of the front flange 26b may be 0 (zero). Note that the drain port insertion portion 25 may not have a tapered shape but may be a tubular body having a constant outer diameter.

Further, as shown in FIG. 1(b), a plurality of vertical ribs 28 having a triangular shape when viewed from the side are formed along the circumferential direction at the corner between the bent portion 24 and the flange portion 26. ing. This vertical rib 28 reinforces the flange portion 26 and prevents it from being damaged. Particularly on the front side, since the degree of protrusion of the front flange 26b is small, the strength can be improved by the vertical ribs 28.
