Description

The present invention relates to a drainage socket that connects an outlet of a toilet bowl body and a drainage port provided on a floor surface.

In the conventional Western-style toilet device, when the toilet body is installed so that the outlet of the toilet body (trap) and the drainage port provided on the floor are separated in a plane, the separation distance is taken into consideration. Therefore, a drainage socket is used (see, for example, Patent Document 1).

The flange portion provided so as to protrude around the bent portion of the drainage port connection portion of this type of drainage socket has a substantially circular outer shape in a plane. For example, the same applies to Patent Document 1, and among the flange portions, the side flanges located on both sides of the bent portion and the front flange located on the front side of the bent portion have the same degree of protrusion from the bent portion. There is. The side flange is provided with a screw fixing hole, and the screw fixing hole is not provided on the front side of the bent portion.

Even though the screw fixing holes are not opened in this way, the fact that the front flange of the flange part protrudes in the same way as the side flange is different from the drain socket body that is directly attached to the drain port. This is to ensure that the floor flange with the insertion part of the body is covered. Further, in consideration of such a double structure, it is possible to provide a screw fixing hole even in the front flange that is greatly projected. If such a floor flange is provided, the displacement between the drain port on the bent portion side and the drain port on the floor surface can be absorbed, but for that purpose, the front flange needs to be greatly projected.

By the way, when the drainage socket as described above is used, it is naturally necessary to hide the connection portion between the drainage port connection portion and the drainage port of the drainage socket with the peripheral wall of the toilet bowl body. Therefore, the toilet bowl body must be installed so that the front flange of the flange portion is also covered with the peripheral wall. That is, if the degree of protrusion of the front flange is large, the toilet body must be installed so that the front end portion of the peripheral wall is arranged in front of the tip position of the front flange.

Therefore, the greater the degree of protrusion of the front flange, the greater the distance between the toilet bowl body and the rear wall of the toilet room must be installed, and the conditions and restrictions on the installation position of the toilet bowl body become stricter for remodeling. May not be possible.

The present invention has been proposed in consideration of such circumstances, and an object of the present invention is to provide a drainage socket capable of relaxing the conditions and restrictions of the installation position of the toilet bowl body.

In order to achieve the above object, the drainage socket of the present invention is a drainage socket that connects the outlet of the toilet body and the drainage port provided on the floor surface, and is a toilet connection portion connected to the outlet. A drainage port connection portion connected to the drainage port, a toilet bowl connection portion, and a horizontal pulling pipe portion connecting the drainage port connection portion, and the drainage port connection portion is an end of the horizontal pulling pipe portion. A bent portion arranged so as to extend from the portion, a drain port insertion portion attached to the drain port extending in a tubular shape so as to communicate with the inside of the bent portion, the bent portion, and the drain port insertion portion. It is provided with a flange portion installed on the floor surface protruding in the circumferential direction at the boundary on the outer surface side between the flange portions, and the flange portion is provided on both sides of the bent portion in a direction orthogonal to the extending direction of the laterally pulled pipe portion. It is provided with at least a side flange having a screw fixing hole and a front flange located on the opposite side of the horizontal pulling pipe portion, and the degree of protrusion of the front flange is smaller than the degree of protrusion of the side flange. It is characterized by that.

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

It is explanatory drawing of the drainage socket which concerns on one Embodiment of this invention. (A) is a vertical cross-sectional view of the drainage socket, (b) is a plan view of the drainage port connection portion of the drainage socket, and (c) is the same perspective view. It is a vertical sectional view which shows the installation mode of the drainage socket with respect to the 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. 1A.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. First, the outline basic configuration of the drainage socket 20 will be described. In the following, the front-back, up-down, and other directions will be defined and described with reference to the toilet bowl device 1 to which the drainage socket 20 is attached.

As shown in FIGS. 1 and 2, the drainage socket 20 connects the outflow port 13 of the toilet bowl main body 10 and the drainage port 7 provided on the floor surface 5. It is provided with a toilet bowl connection portion 21 connected to the outflow port 13, a drainage port connection portion 23 connected to the drainage port 7, and a horizontal piping portion 22 connecting the toilet bowl connection portion 21 and the drainage port connection portion 23. ..

The drainage port connecting portion 23 is configured to include a bent portion 24, a drainage port insertion portion 25, and a flange portion 26. The bent portion 24 is arranged so as to extend from the end of the horizontal pulling pipe portion 22, and the drain port insertion portion 25 is a portion to be inserted and attached to the drain port 7, so that the inside communicates with the bent portion 24. It extends in a tubular shape. The outer shape of the drainage port insertion portion 25 has a tapered shape that is tapered downward by changing the thickness of the pipe. Further, as shown in FIGS. 1 (b) and 1 (c), the flange portion 26 is a portion installed on the floor surface 5, and is in the circumferential direction at the boundary on the outer surface side between the bent portion 24 and the drain port insertion portion 25. It protrudes into.

The flange portion 26 is located on both sides of the bent portion 24 in the direction orthogonal to the extending direction of the lateral pulling pipe portion 22, and is located on the side opposite to the horizontal pulling piping portion 22 and the side flange 26a having the screw fixing holes 26aa. It 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 flange 26a.

Further, as shown in FIG. 2, the toilet bowl device 1 to which the drainage socket 20 is attached includes the toilet bowl main body 10 and a peripheral wall 15 surrounding the toilet bowl main body 10. The toilet body 10 has a bowl 11 having a mortar-shaped bottom side narrowed, 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). I have.

This trap 12 is a mechanically operated type, and as shown by the two-dot chain arrow in FIG. 2, it has a tubular shape so that it can be switched between the water sealing posture (upper position) and the draining posture (lower position). It has a bellows structure. The trap 12 is arranged in the trap case 14, and the drainage 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 bowl body 10). There is. The outlet 13 has a tubular shape and is connected to the drainage inlet portion 21a of the drainage socket 20.

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

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

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

Next, the detailed configuration of the drainage socket 20 and the relationship between the drainage socket 20 and the toilet bowl device 1 will be described in detail with reference to FIGS. 1 to 3.

As described above, the drainage socket 20 includes the toilet bowl connection portion 21, the horizontal piping portion 22, and the drainage port connection portion 23, but the one of the present embodiment is different from the division of each portion. It is composed of three separable members. Specifically, the drainage socket 20 is composed of three members, a first constituent member 31, a second constituent member 32, and an adjusting connector 33.

As shown in FIG. 1A, the first constituent member 31 includes a toilet bowl connecting portion 21 having a drainage inlet portion 21a and a part of a tubular portion 31a on the toilet bowl connecting portion 21 side of the horizontal pulling pipe portion 22. Is an integrated member. An installation base 31c for stably installing the first component 31 on the floor surface 5 is integrally formed below the drainage inlet portion 21a of the first component 31.

The second component 32 is a member corresponding to the drainage port connecting portion 23 connected to the horizontal pulling pipe portion 22 (see FIGS. 1B and 1C), and therefore, the drainage port connecting to the toilet bowl side. The toilet bowl side opening 32a having a diameter larger than that of the main body cylinder portion of the portion 23 is provided. The lower part of the outer surface of the toilet bowl side opening 32a is thickly formed for height adjustment.

Further, the adjusting connector 33 connects the adjusting connector 33 itself between the first constituent member 31 and the second constituent member 32, thereby connecting the tubular portion 31a of the first constituent member 31 and the adjusting connector 33. This is a tubular member for forming the horizontal pulling piping portion 22. It is desirable that the inner bottom surface of the horizontal pulling pipe portion 22 is provided with a water gradient for drainage.

The adjusting connector 33 has a large diameter portion 33a and a small diameter portion 33b, and is connected so that the large diameter portion 33a fits outside the drainage side opening 31b of the tubular portion 31a of the first constituent member 31. Will be done. Further, the small diameter portion 33b is connected so as to fit inside the toilet bowl side opening 32a of the second constituent member 32.

Since the drainage socket 20 is a member that connects the position of the trap 12 in the drainage posture (the position of the drainage inlet portion 21a of the toilet bowl connection portion 21) and the drainage port 7 in the front-rear direction, the total length of the drainage socket 20 is It is necessary to roughly match the drainage posture position and the distance between the drainage port 7 positions. In order to obtain such a length, the length of the small diameter portion 33b can be adjusted by cutting. The drainage socket 20 may be configured not to use such an adjusting connector 33. For example, two members (for example, the first constituent member 31 and the second constituent member 32) may be connected, or four members (for example, the first constituent member 31 and the second constituent member 32 and two adjustment connections) may be connected. It may be composed of the tool 33).

The drainage port connecting portion 23 corresponding to the second component 32 includes a toilet bowl side opening 32a, a bent portion 24, a drainage port insertion portion 25, and a flange portion 26. The inside communicates from the toilet bowl side opening 32a to the drain port insertion portion 25 via the bent portion 24.

The drainage port insertion portion 25 is inserted and attached to the drainage port 7, and the drainage inlet portion 21a of the rear toilet bowl connection portion 21 is aligned with the position of the outlet 13 (lower end opening of the trap case 14) of the toilet bowl body 10. The drainage socket 20 is arranged at an appropriate position (see FIGS. 1A and 2). With the drainage socket 20 properly installed in this way, the back surface of the flange portion 26 comes into contact with the floor surface 5.

As shown in FIG. 1B, the flange portions 26 are provided with two side flanges 26a located on both sides of the bent portion 24, that is, on both sides in a direction orthogonal to the longitudinal direction (drainage flow direction) of the lateral pulling pipe portion 22. The front flange 26b located on the front side of the bent portion 24 is provided. The rear portion of the flange portion 26 corresponds to the lower part of the outer surface of the toilet bowl side opening 32a.

As shown in FIG. 1B, the side flanges 26a project on both sides of the bent portion 24 in a plan view in a wing shape with an outer shape curved or polygonal. 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 arranged in the front-rear direction so as to roughly follow the shape of the outer edge.

On the other hand, the front flange 26b protrudes so that the outer shape has a substantially arc shape. The arc is arranged so that both ends thereof are located on the inner side of the outer edge of the side flange 26a (in the direction in which both outer edges approach each other), and are located at the front end edge 26ab of the side flange 26a and the obtuse angle bent portion 26ba. Has been done.

Thus, the front flange 26b connects the front ends of the outer edges of the side flanges 26a to the front without bending so as to draw a concentric arc with the 26b on the front flare 27 (FIG. 1 (b)). It is shaped like a notch so that it is behind the two-dot chain line). That is, the front flange 26b is not formed so that the portion of the side flange 26a provided with the two screw fixing holes 26aa extends forward, and the front flange 26b is also provided with a hole for fixing with a screw. Not.

By forming the front flange 26b in such a shape, the dimension A from the center X of the drainage port 7 (see FIG. 1B) to the outer edge is the dimension from the center X of the drainage port 7 to the outer edge of the side flange 26a. It is sufficiently smaller than B (see FIG. 1 (b)). That is, the front end position C where the center line of the drainage socket 20 and the arc-shaped outer edge of the front flange 26b intersect in a plan view is located behind the front end position D where the center line and the virtual curved line 27 intersect. (See FIG. 1 (b)).

FIG. 3 is a schematic vertical cross-sectional view comparing the front end position C (main drainage socket 20) and the front end position D (drainage socket 200 corresponding to the front end position D). The peripheral wall 15 of the toilet bowl device 1 needs to be installed so that the lower end of the front end portion 15a is arranged in front of the front end position C and the front end position D. Therefore, when the distance between the front end position C and the front end position D and the front end portion 15a of the peripheral wall 15 is the same, the front end portion 15a in the case of the front end position C is better than the front end portion 15a in the case of the front end position D. Is also on the back side.

By making the degree of protrusion of the front flange 26b forward as shown in FIG. 1B smaller than the degree of protrusion of the side flange 26a, the entire toilet bowl device 1 is formed on the rear wall of the toilet room (not shown). Can be approached to. In other words, by making the flange portion 26 of the drain port connection portion 23 of the drain socket 20 into a shape as shown in FIG. 1B, the conditions and restrictions on the installation position of the toilet bowl body 10, that is, the toilet bowl device 1 are reduced. , It leads to increase the degree of freedom of installation position.

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 hole 26aa provided in the side flange 26a. Therefore, if the drainage socket 20 is properly arranged, substantially the entire flange portion 26 is in close contact with the floor surface 5. Therefore, stable installation of the drainage socket 20 can be realized.

Further, since the drainage port insertion portion 25 is fitted inside the drainage port 7 and the flange portion 26 is in close contact with the floor surface 5, it is possible to prevent the drainage port connection portion 23 of the drainage socket 20 from being displaced or tilted. , Leakage of drainage can also be prevented.

Further, since the drainage port insertion portion 25 is integrally formed with the drainage port connection portion 23 as a part of the drainage socket 20, a separate floor flange used for attaching the conventional drainage socket is not required. Therefore, it is necessary to form the drainage port insertion portion 25 so that there is no dimensional error with respect to the drainage port 7. However, in the case of the present embodiment, since the drainage port insertion portion 25 has a tapered shape that is recessed downward, it can be firmly attached to the drainage port 7 even if there is some error.

Since the drainage socket 20 has such a structure, there is no problem even if the front flange 26b of the flange portion 26 is not screwed. Therefore, there is no problem in the installation strength of the drainage socket 20 in making the degree of protrusion of the front flange 26b smaller than the degree of protrusion of the side flange 26a.

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 (FIG. 1). As long as b)) is as far back as possible, various shapes are acceptable. For example, the front flange 26b may have a shape in which the two bent portions 26ba in FIG. 1B are connected by a straight line and the front side thereof is cut off. Furthermore, if the drainage port insertion portion 25 is securely attached to and fixed to the drainage port 7 within the vertical dimension thereof (within the range of the tapered surface), the front flange 26b is not substantially formed. May be good. That is, the protruding dimension of the front flange 26b may be 0 (zero). The drainage port insertion portion 25 may have a constant outer diameter instead of a tapered shape.

Further, as shown in FIG. 1B and the like, a plurality of triangular vertical ribs 28 are formed in the side view along the circumferential direction at the entrance corners of the bent portion 24 and the flange portion 26. ing. The vertical rib 28 reinforces the flange portion 26 and prevents damage. In particular, on the front side, since the degree of protrusion of the front flange 26b is small, the strength can be improved by the vertical rib 28.
