The present invention relates to a drainage sleeve connecting the outflow port of the toilet body and the drainage port opened on the floor surface.

In the conventional Western-style toilet device, when the toilet body was installed so that the outflow port of the toilet body (the water trap) and the drain opening opened on the floor surface were separated on the plane, the separation distance was considered and used. Drainage jacket (for example, refer to Patent Document 1).

The planar outline of the flange portion provided to protrude to the periphery of the curved portion of the drain connection portion of the drain sleeve is approximately circular. For example, in the drain sleeve of Patent Document 1, in the flange portion, the side flanges located on both sides of the curved portion and the front flange located on the front side of the curved portion protrude from the curved portion to the same extent. In addition, a screw fixing hole is provided on the side flange, and a screw fixing hole is not provided on the front side of the curved portion.

In this way, the front flange of the flange portion is protruded in the same way as the side flanges even though the screw fixing holes are not provided, so as to surely cover the floor flange with the insertion portion which is directly installed on the drain outlet and is separated from the drain casing body. the reason. In addition, considering such a dual structure, the flange can also be provided with screws for fixing before it protrudes significantly. hole. In addition, if such a floor flange is provided, the positional deviation of the discharge port on the side of the curved portion and the water discharge port on the floor surface can be absorbed, but the front flange needs to protrude significantly.

Furthermore, as shown in FIG. 2 , the toilet device 1 to which the drain sleeve 20 is attached includes the toilet body 10 described above and a peripheral wall 15 surrounding the toilet body 10 . The toilet body 10 has a bedpan 11 whose bottom is narrowed into a mortar-like shape, a water trap 12 connected to an outlet 11a on the bottom side of the bedpan 11, a toilet seat (not shown in the figure), and a toilet cover (not shown in the figure). .

The water trap 12 is a mechanical action type, as shown by the arrow of the two-dotted chain line in FIG. 2 , it has a cylindrical expansion bag structure and can be switched between the water sealing position (up position) and the drain position (down position). . The trap 12 is arranged in the trap box 14, and the drainage discharged from the outlet 12a of the trap 12 is discharged from the opening at the lower end of the trap box 14 (the outlet 13 of the toilet body 10). The outflow port 13 has a cylindrical shape and is connected to the drain inlet portion 21 a of the drain sleeve 20 .

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

Moreover, this peripheral wall 15 is also arrange|positioned so that the said drain port 7 may be enclosed. The drain port 7 is located in front of the outflow port 13 of the toilet body 10 and below the front portion of the toilet bowl 11 . The drain port 7 is connected to the drain port insertion portion 25 of the drain port connecting portion 23 of the drain sleeve 20 . Therefore, the drain sleeve 20 arranged to connect the outflow port 13 of the toilet body 10 and the drain port 7 is also hidden by the peripheral wall 15 .

The toilet device 1 that can be equipped with the drain casing 20 is not limited to the toilet device having the machine-operated water trap 12 as shown in FIG. Such a drain sleeve 20 can be used in a toilet device in which at least the drain port 7 provided on the floor surface 5 and the outflow port 13 of the toilet body 10 are spaced apart in the front-rear direction.

Next, the detailed structure of the drain sleeve 20 and the relationship between the drain sleeve 20 and the toilet device 1 will be described in detail according to FIGS. 1 to 3 .

As described above, the drain bushing 20 includes the toilet connecting portion 21, the horizontal piping portion 22, and the drain port connecting portion 23, but the drain bushing 20 of the present embodiment has a structure of three components that can be separated into three different parts. become. Specifically, the drain jacket 20 is composed of three members: a first structural member 31 , a second structural member 32 , and an adjustment coupling 33 .

As shown in FIG. 1( a ), the first constituent material 31 is a member integrated with the toilet connecting portion 21 of the drain inlet portion 21 a and the cylindrical portion 31 a which is a part of the horizontal piping portion 22 on the toilet connecting portion 21 side. Moreover, the installation base part 31c for stably installing the 1st structural material 31 on the floor surface 5 is integrally formed in the lower side of the drain inlet part 21a of the 1st structural material 31.

The second constituent material 32 corresponds to a member connected to the drain port connecting portion 23 of the horizontal piping portion 22 (refer to FIGS. 1(b) and (c) ), and therefore, has a body tube with a larger diameter than the drain port connecting portion 23 on the toilet side. The toilet side opening part 32a of the part. The lower part of the outer surface of the toilet-side opening 32a is thickened to adjust the height.

In addition, the adjustment coupling tool 33 is configured by the cylindrical portion 31 a of the first structural member 31 and the adjustment coupling tool 33 by connecting the adjustment coupling member 33 itself between the first structural member 31 and the second structural member 32 . The cylindrical member of the horizontal piping portion 22 . In addition, it is desirable to provide a drainage slope for drainage on the inner bottom surface of the horizontal piping portion 22 .

This adjustment coupling 33 has a large diameter portion 33a and a small diameter portion 33b, and the large diameter portion 33a is externally connected to the drain side opening 31b of the cylindrical portion 31a of the first structural member 31 . Moreover, the small diameter part 33b is connected to the toilet-side opening part 32a of the 2nd structural material 32 so that it may be fitted inside.

Since the drain sleeve 20 is a member that connects the position of the water trap 12 in the drain posture (the position of the drain inlet portion 21a of the toilet connection portion 21) and the drain port 7 in the front-rear direction, the entire length of the drain sleeve 20 needs to be matched with the drain port 7. The distance between the posture position and the position of the drain port 7 is approximately the same. To create this length, the small diameter can be cut off The length of the portion 33b is adjusted. In addition, the drainage sleeve 20 can also be a structure without using such an adjustment coupling 33 . For example, it may be a structure in which two members (eg, the first constituent material 31 and the second constituent member 32 ) are connected, or four members (eg, the first constituent member 31 , the second constituent member 32 , and two adjustment members) may be used. The structure formed by the coupling device 33).

The water outlet connection portion 23 corresponding to the second constituent material 32 includes a toilet-side opening portion 32 a , a curved portion 24 , a water outlet insertion portion 25 , and a flange portion 26 . The inside is communicated from the toilet-side opening portion 32a to the drain port insertion portion 25 via the curved portion 24 .

By inserting and installing the drain port insertion portion 25 in the drain port 7, the drain inlet portion 21a of the toilet connecting portion 21 at the rear is arranged to be connected with the outflow port 13 of the toilet body 10 (the lower end of the trap box 14 is open). The position of the part) is the same, and the drainage sleeve 20 can be arranged in an appropriate position (refer to FIG. 1(a) and FIG. 2). In a state where the drain sleeve 20 is properly installed in this manner, the back surface of the flange portion 26 abuts on the floor surface 5 .

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

As shown in FIG. 1( b ), the side flanges 26a protrude into a wing shape on both sides of the curved portion 24 in a plan view by making the outer shape curved or polygonal. The side flanges 26a are respectively provided with two screw fixing holes 26aa which are arranged in a shape approximately along the outer edge and are connected to the floor surface 5 by screws.

On the other hand, the front flange 26b protrudes in an approximately circular arc shape. Both ends of the circular arc are located inside the outer edge of the side flange 26a (in the direction in which the two outer edges approach), and the circular arc is located at a position where the obtuse-angled bent portion 26ba is continuous with the front end edge 26ab of the side flange 26a .

In short, the front flange 26b is in the shape of a notch formed by retreating rearwardly by an imaginary bending line 27 (two-dot chain line in FIG. They are connected to each other so as to draw an arc concentric with the front flange 26b forward without being bent. That is, the portion of the side flange 26a where the two screw fixing holes 26aa are provided is not formed in the front flange 26b so as to extend to the front, nor is the front flange 26b provided with a screw fixing hole. Specifically, in each of the two side flanges 26a, a portion protruding from the front flange 26b is provided with a screw fixing hole 26aa.

If the front flange 26b has such a shape, the dimension A from the center X (refer to FIG. 1(b)) of the drain port 7 to the outer edge is much smaller than the dimension A from the center X of the drain port 7 to the outer edge of the side flange 26a. Dimension B (refer to Fig. 1(b)). That is, the front end position C where the center line of the drain sleeve 20 intersects with the arcuate outer edge of the front flange 26b in plan view is located behind the front end position D where the center line intersects the virtual bending line 27 (see FIG. 1(b). )).

FIG. 3 is a schematic longitudinal sectional view comparing the front end position C (the present drainage sleeve 20 ) and the front end position D (the drainage sleeve 200 corresponding to the front end position D). The peripheral wall 15 of the toilet device 1 needs to be arranged 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 distances between the leading end position C, the leading end position D and the leading end portion 15a of the peripheral wall 15 are the same, the leading end portion 15a at the leading end position C is more rearward than the leading end portion 15a at the leading end position D.

All in all, as shown in FIG. 1(b), by making the front flange 26b protrude forward less than the side flange 26a, the toilet device 1 as a whole can be close to the rear wall of the toilet (not shown). In other words, make the drain jacket The shape of the flange portion 26 of the water outlet connecting portion 23 of the pipe 20 as shown in FIG.

Moreover, the back surface of the flange part 26 (surface on the side of the drain insertion part 25) is substantially flat except for the screw fixing hole 26aa provided in the side flange 26a. Therefore, if the drain sleeve 20 is appropriately arranged, the flange portion 26 can be brought into close contact with the floor surface 5 in its entirety. Therefore, stable setting of the drain sleeve 20 can be achieved.

In addition, since the structure is that the drain port insertion portion 25 is embedded in the drain port 7, and the flange portion 26 is in close contact with the floor surface 5, the drain port connecting portion 23 of the drain sleeve 20 can be prevented from being deviated or inclined, and the leakage of the drain can be prevented. leakage.

In addition, since the drain insertion portion 25 is integrally formed with the drain connection portion 23 as a part of the drain sleeve 20, a separate floor flange used in the installation of the conventional drain sleeve is not required. 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, since the drain port insertion portion 25 is formed in a tapered shape narrowing downward, the drain port 7 can be properly installed even if there is a slight error.

Since the present drain bushing 20 has such a structure, there is no problem even if the flange 26b is not screwed before the flange portion 26 . All in all, the protruding degree of the front flange 26b is made smaller than the protruding degree of the side flange 26a, so that the installation strength of the drain sleeve 20 does not have a problem.

In addition, in the above-described embodiment, the shape of the flange 26b before the flange portion 26 is arc-shaped, but other shapes may be used, as long as the degree of protrusion is small, that is, as long as the front end position C (refer to FIG. 1 ( b)) As far back as possible, various shapes can be tolerated. For example, the front flange 26b can also be formed in a shape in which the two bent portions 26ba of FIG. 1(b) are connected in a straight line and the front side thereof is cut off. Furthermore, if the drain port insertion portion 25 is The front flange 26b may not be substantially formed if it is securely installed and fixed to the drain port 7 within an inch (within the range of the tapered surface). That is, the protruding dimension of the front flange 26b may also be 0 (zero). In addition, the water outlet insertion portion 25 may not be tapered, but may be a pipe body with a certain outer diameter.

Moreover, as shown in FIG.1(b) etc., the internal corner part of the curved part 24 and the flange part 26 is formed with the longitudinal direction rib 28 of a plurality of triangular shape in side view along the circumferential direction. Accordingly, the longitudinal ribs 28 can reinforce the flange portion 26 to prevent breakage. Especially on the front side, since the protruding degree of the front flange 26b is small, the strength of the longitudinal rib 28 can be improved.
