Description

Drain pipe seat

Technical Field

The present invention relates to a drain pipe base for connecting an outlet of a toilet body to a drain port formed in a floor surface.

Background

In a conventional western-style toilet apparatus, when a toilet main body is provided so that an outlet port of (a return water trap of) the toilet main body and a drain port opened in a floor surface are separated in a planar manner, a drain pipe base is used in consideration of the separation distance (for example, see patent document 1).

The flange portion provided so as to protrude around the bent portion of the drain port connecting portion of the drain socket has a substantially circular planar outer shape. For example, in the structure of patent document 1, the protruding dimensions of the side flanges on both sides of the bent portion and the front flange on the front side of the bent portion among the flanges are set to be the same. Further, the side flange is provided with a screw fixing hole, and the bent portion is not provided with a screw fixing hole on the front side.

Although no screw fixing hole is formed in this way, the front flange of the flange portion projects like the side flange, and the purpose is to reliably cover the floor flange with an insertion portion that is directly attached to the drain port and is separate from the drain pipe base body. In addition, considering such a double structure, a screw fixing hole can be provided in the front flange that protrudes largely. Further, if such a floor flange is provided, it is possible to absorb the positional deviation between the discharge port on the bent portion side and the discharge port on the floor surface, but for this reason, it is necessary to make the front flange protrude largely.

Disclosure of Invention

Problems to be solved by the invention

In addition, when the drain socket as described above is used, it is necessary to shield the connection portion between the drain port connection portion and the drain port of the drain socket with the peripheral wall of the toilet main body. Therefore, the toilet main body must be provided so that the front flange of the flange portion is also covered with the peripheral wall. That is, if the front flange protrudes to a large extent, the toilet main body must be disposed so that the front end portion of the peripheral wall is disposed forward of the front end position of the front flange.

In short, the toilet main body must be installed so as to be spaced further away from the rear wall of the toilet room as the degree of protrusion of the flange increases, and the conditions and restrictions on the installation position of the toilet main body become strict, and there is a possibility that the toilet main body cannot be adapted to the modification.

The present invention has been made in view of such circumstances, and an object thereof is to provide a drain socket capable of alleviating the conditions and restrictions on the installation position of a toilet body.

Means for solving the problems

In order to achieve the above object, a drain socket according to the present invention is a drain socket for connecting an outlet of a toilet main body to a drain port opened in a floor surface, the drain socket including a toilet connection portion connected to the outlet, a drain port connection portion connected to the drain port, and a lateral guide pipe portion connecting the toilet connection portion and the drain port connection portion; the drain port connecting portion includes a bent portion arranged to extend from an end of the lateral guide pipe portion, a drain port insertion portion attached to the drain port and extending in a cylindrical shape so as to communicate the inside with the bent portion, and a flange portion provided on the floor surface and protruding outward at a boundary on the outer peripheral surface side between the bent portion and the drain port insertion portion; the flange portion includes at least a side flange having a screw fixing hole and located on both sides of the bent portion in a direction orthogonal to a direction in which the lateral guide piping portion extends, and a front flange located on a side opposite to the lateral guide piping portion, and the front flange is configured to protrude less than the side flange.

Effects of the invention

Since the drain pipe base of the present invention is configured as described above, the conditions and restrictions on the installation position of the toilet main body can be alleviated.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, a schematic basic structure of the drain pipe base 20 will be described. In the following, directions such as front-back and up-down are defined with reference to the toilet bowl apparatus 1 to which the drain socket 20 is attached.

As shown in fig. 1 and 2, the drain pipe base 20 connects the outlet 13 of the toilet body 10 to the drain port 7 opened in the floor 5. The toilet connection unit 21 is connected to the outlet 13, the outlet connection unit 23 is connected to the outlet 7, and the lateral guide pipe unit 22 connects the toilet connection unit 21 and the outlet connection unit 23.

The drain port connecting portion 23 includes a bent portion 24, a drain port insertion portion 25, and a flange portion 26. The bent portion 24 is disposed so as to extend from an end portion of the lateral guide pipe portion 22, and the drain opening insertion portion 25 is a portion to be inserted into and attached to the drain opening 7, and extends in a cylindrical shape so as to communicate the inside with the bent portion 24. The outer shape of the drain port insertion portion 25 is tapered so as to narrow downward by changing the thickness of the pipe. As shown in fig. 1 (b) and (c), the flange 26 is provided on the floor 5, and protrudes outward at the boundary on the outer peripheral surface side between the bent portion 24 and the drain opening insertion portion 25.

The flange portion 26 includes at least: side flanges 26a having screw fixing holes 26aa located on both sides in a direction orthogonal to a direction in which the lateral guide pipe portion 22 of the bending portion 24 extends; and a front flange 26b located on the opposite side of the lateral guide piping portion 22. The front flange 26b protrudes to a lesser extent than the side flanges 26 a.

Further, as shown in fig. 2, the toilet apparatus 1 to which the drain pipe holder 20 is attached includes 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 whose bottom portion is narrowed into a mortar shape, a return water trap 12 connected to an outlet 11a on the bottom portion side of the bowl 11, a toilet seat (not shown), and a toilet lid (not shown).

The return water pipe 12 is of a mechanical operation type, and is formed in a cylindrical bellows structure so as to be switchable between a water-blocking posture (upper position) and a water-discharging posture (lower position) as indicated by an arrow with a two-dot chain line in fig. 2. The return water trap 12 is disposed in the return water trap housing 14, and the drain discharged from the outlet 12a of the return water trap 12 is discharged from the lower end opening of the return water trap housing 14 (the outlet 13 of the toilet bowl body 10). The outlet 13 is cylindrical and connected to the drain inlet 21a of the drain stem 20.

The peripheral wall 15 of the toilet body 10 is disposed around the toilet bowl 11 and the return water elbow 12 so as to shield them.

The peripheral wall 15 is also arranged to surround the drain opening 7. The water discharge port 7 is located forward 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 a drain port insertion portion 25 of the drain port connection portion 23 of the drain stem 20. Therefore, the drain stem 20 disposed so as to connect the outlet 13 of the toilet body 10 to the drain port 7 is also shielded by the peripheral wall 15.

The toilet apparatus 1 in which the drain socket 20 can be disposed is not limited to the configuration having the mechanically-operated return water trap 12 shown in fig. 2, and can be applied to a toilet apparatus having a fixed return water trap. The drain socket 20 can be used as long as it is configured such that the drain port 7 provided at least on the floor surface 5 and the outlet port 13 of the toilet main body 10 are separated 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 apparatus 1 will be described in detail with reference to fig. 1 to 3.

The drain socket 20 includes the toilet connection portion 21, the lateral guide pipe portion 22, and the drain opening connection portion 23 as described above, but the configuration of the present embodiment is configured by 3 members that can be separated so as to be different from the division of these portions. Specifically, the drain socket 20 is composed of 3 members, i.e., a 1 st component 31, a 2 nd component 32, and an adjustment tool 33.

As shown in fig. 1 (a), the 1 st component 31 is a member in which a toilet connection portion 21 having a drain inlet portion 21a and a cylindrical portion 31a that is a part of the lateral guide pipe portion 22 on the toilet connection portion 21 side are integrated. Further, a mounting table portion 31c for stably mounting the 1 st component 31 on the floor 5 is integrally formed below the drain inlet portion 21a of the 1 st component 31.

The 2 nd component 32 is a member corresponding to the drain port connecting portion 23 connected to the lateral guide pipe portion 22 (see fig. 1 (b) and (c)), and for this purpose, a toilet side opening portion 32a having a larger diameter than the main body tube portion of the drain port connecting portion 23 is provided on the toilet side. The lower portion of the outer surface of the toilet side opening 32a is formed thick for height adjustment.

The adjustment connecting tool 33 is a tubular member for forming the lateral guide pipe portion 22 by the tubular portion 31a of the 1 st component 31 and the adjustment connecting tool 33 by connecting the adjustment connecting tool 33 itself between the 1 st component 31 and the 2 nd component 32. Further, a drain slope for draining water is preferably provided on the inner bottom surface of the lateral guide pipe portion 22.

The adjustment connecting tool 33 has a large diameter portion 33a and a small diameter portion 33b, and the large diameter portion 33a is connected to the drain side opening portion 31b of the cylindrical portion 31a of the 1 st component 31 so as to be externally fitted. The small diameter portion 33b is connected so as to fit into the toilet side opening 32a of the 2 nd component 32.

The drain pipe base 20 is a member that connects the position in the drainage posture of the return water elbow 12 (the position of the drainage inlet portion 21a of the toilet connecting portion 21) and the drainage port 7 in the front-rear direction, and therefore, it is necessary to make the entire length of the drain pipe base 20 substantially coincide with (match, coincide with) the distance between the drainage posture position and the drainage port 7 position. In order to achieve such a length, the small diameter portion 33b may be cut to adjust the length. The drain pipe base 20 may be configured without using the adjustment tool 33. For example, the structure may be such that two members (for example, the 1 st component 31 and the 2 nd component 32) are coupled, or the structure may be such that four members (for example, the 1 st component 31, the 2 nd component 32, and the two adjustment coupling tools 33) are coupled.

The drain port connecting portion 23 corresponding to the 2 nd component 32 is configured to include a toilet side opening portion 32a, a bent portion 24, a drain port insertion portion 25, and a flange portion 26. The interior of the toilet side opening 32a communicates with the drain port insertion portion 25 via the bent portion 24.

The outlet insertion portion 25 is inserted into and attached to the outlet 7, and the drain inlet 21a of the toilet connection portion 21 on the rear side is arranged at a position matching the outlet 13 of the toilet body 10 (the lower end opening of the return elbow housing 14), whereby the drain stem 20 is arranged at a correct position (see fig. 1a and 2). In the state where the drain pipe base 20 is thus accurately provided, the back surface of the flange portion 26 abuts against the floor surface 5.

As shown in fig. 1 (b), the flange portion 26 includes: 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 (drain flow direction) of the lateral guide pipe portion 22; and a front flange 26b located on the front side of the bent portion 24. The rear portion of the flange portion 26 corresponds to the lower portion of the outer surface of the toilet side opening 32 a.

As shown in fig. 1 (b), the side flange 26a is formed to have a curved or polygonal outer shape on both sides of the curved portion 24 in a planar view and to protrude in a wing shape. Two screw fixing holes 26aa for connecting the screw to the ground 5 are opened in the side flanges 26a, respectively, so as to be arranged in a front-rear direction substantially along the outer edge.

On the other hand, the front flange 26b protrudes so as to have a substantially circular arc shape in outer shape. The arc has both ends located inside the outer edges of the side flanges 26a (in the direction in which the outer edges approach each other), and is located so as to be continuous with the leading end edges 26ab of the side flanges 26a via an obtuse-angle-shaped bent portion 26 ba.

In short, the front flange 26b is cut out so as to be pressed rearward from a virtual bending line 27 (a two-dot chain line in fig. 1 (b)), and the virtual bending line 27 connects the front ends of the outer edges of the side flanges 26a to draw an arc concentric with the front flange 26b forward without bending each other. 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 forward, and the front flange 26b is also not provided with holes for fixing with screws.

By forming the front flange 26B in such a shape, a dimension a from the center X (see fig. 1B) of the drain opening 7 to the outer edge is sufficiently smaller than a dimension B from the center X of the drain opening 7 to the outer edge of the side flange 26a (see fig. 1B). That is, the front end position C where the center line of the drain stem 20 intersects the outer edge of the arc shape of the front flange 26b in plan view is located rearward of 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 a front end position C (the present drain socket 20) with a front end position D (the drain socket 200 corresponding to the front end position D). The peripheral wall 15 of the toilet apparatus 1 needs to be provided such that the lower end of the distal end portion 15a is disposed forward of the distal end position C and the distal end position D. Therefore, when the distances between the front end position C, the front end position D, and the front end portion 15a of the peripheral wall 15 are made the same, the front end portion 15a in the case of the front end position C is located more rearward than the front end portion 15a in the case of the front end position D.

In short, the forward projection of the front flange 26b as shown in fig. 1 (b) is smaller than the projection of the side flange 26a, whereby the entire toilet apparatus 1 can be brought close to the rear wall (not shown) of the toilet. In other words, by forming the flange portion 26 of the drain port connecting portion 23 of the drain socket 20 into the shape shown in fig. 1 (b), the conditions and restrictions on the installation position of the toilet main body 10, i.e., the toilet apparatus 1, are reduced, and the degree of freedom in the installation position is increased.

The rear surface of the flange 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 flanges 26 a. Therefore, if the drain pipe base 20 is appropriately arranged, the flange portion 26 is closely attached to the floor surface 5 substantially entirely. Therefore, the drain stem 20 can be stably installed.

Further, since the drain port insertion portion 25 is fitted into the drain port 7 and the flange portion 26 is in close contact with the floor surface 5, the drain port connection portion 23 of the drain stem 20 can be prevented from being displaced or inclined, and leakage of drain water can be prevented.

Further, since the drain port insertion portion 25 is formed integrally with the drain port connecting portion 23 as a part of the drain stem 20, a separate floor flange used for mounting the conventional drain stem is not required. Therefore, the drain opening insertion portion 25 needs to be formed without dimensional error with respect to the drain opening 7. However, in the structure of the present embodiment, since the drain opening insertion portion 25 has a tapered shape that narrows downward, it can be firmly attached to the drain opening 7 even with some error.

Since the drain pipe base 20 is structured as described above, there is no problem even if the screw fixing is not performed on the front flange 26b of the flange portion 26. In short, the front flange 26b is less protruded than the side flange 26a, and there is no problem in the installation strength of the drain socket 20.

In the embodiment described above, the front flange 26b of the flange portion 26 is formed in an arc shape, but other shapes are acceptable as long as the degree of protrusion is small, that is, as long as the front end position C (see fig. 1 (b)) is located as rearward as possible. For example, the front flange 26b may be formed in a shape in which two bent portions 26ba in fig. 1 (b) are connected by a straight line and the front side thereof is cut out. Further, the front flange 26b may not be substantially formed as long as the drain opening insertion portion 25 is reliably attached and fixed to the drain opening 7 within the vertical dimension (within the range of the tapered surface). That is, the projecting dimension of the front flange 26b may be 0 (zero). The drain port insertion portion 25 may not be tapered, and may be a pipe having a constant outer diameter.

As shown in fig. 1 (b), a plurality of vertical ribs 28 having a triangular shape in side view are formed along the circumferential direction at the inner corner portions of the bent portion 24 and the flange portion 26. The flange 26 is reinforced by the vertical ribs 28, and breakage can be prevented. Particularly on the front side, the front flange 26b protrudes to a small extent, so that the longitudinal rib 28 can improve the strength.
