Description

  The present invention relates to a drainage socket of a flush toilet, and in particular, an inlet end of a drainage pipe provided at a position higher than a floor surface branched from a vertical drainage pipe installed in a vertical direction in a wall surface or toilet and a flush toilet body The present invention relates to a drainage socket of a flush toilet that communicates with the outlet end of the drainage channel.

  Conventionally, as shown in FIG. 14, in order to connect the drainage channel 212 of the flush toilet to the drainage pipeline D1 of the wall surface W1, the drainage socket 232 in which the height of the drainage socket 232 relative to the pedestal portion 234 can be adjusted by a screw 248. Is known (Patent Document 1).

  Here, the pedestal portion 234 usually has to be arranged in a predetermined direction in order to match the screw hole formed on the floor surface. In the drain socket 232 described above with respect to such a requirement, the pitch of the screw portion 248 is made smaller than the dimensional tolerance between the outlet portion of the drain channel 212 and the drain pipe D1. After the height of the outlet portion and the drainage pipe D1 are substantially matched, the pedestal portion 234 is rotated and positioned in the screw hole on the floor surface, thereby positioning the pedestal portion 234 and draining the outlet portion of the drainage channel 212. The positioning to the pipe line D1 was made compatible.

  However, since the strength of such a thread portion with a small pitch is reduced, there is a problem that the screw thread is damaged when a large load is applied to the drain socket when constructing the flush toilet. On the other hand, increasing the pitch solves the strength problem, but in this case, it is difficult to achieve both positioning of the pedestal and positioning of the outlet of the drainage channel to the drainage pipe. That is, if the pedestal is rotated to adjust to an appropriate position, the outlet of the drainage channel may not be aligned with the drainage pipe on the wall surface, and vice versa. Such a problem has become a significant problem when a panel is placed on the floor and raised during remodeling such as changing the toilet bowl.

The present invention has been made to solve the above-described problems of the prior art, and easily achieves both positioning of the pedestal portion on the floor surface and positioning of the water pipe and drainage pipe of the flush toilet. An object of the present invention is to provide a drainage socket for a flush toilet.

And a pedestal portion that supports the drain socket body, and the pedestal portion is configured such that the height from the floor surface of the outlet of the drain socket body substantially matches the height from the floor surface of the drain pipe. in, stand by relatively rotating the height adjusting member It is characterized in that it is possible to adjust the position to be fixed to the floor parts.
In the present invention configured as described above, the positioning tolerance between the height from the floor of the outlet of the drain socket body and the height from the floor of the drain pipe provided on the wall surface is very small. Even if there is first, the height from the floor surface of the outlet of the drain socket body is determined by the height adjustment unit, and then, if the pedestal portion is rotated relative to the height adjustment member, any of the pedestal portion It can be fixed on the floor at the position. As a result, the positioning of the pedestal portion on the floor and the positioning of the water distribution pipe and the drainage pipe of the flush toilet can be easily made compatible.

In the present invention, preferably, the height adjusting portion is a screw portion.
In this invention comprised in this way, since it has a thread part (combination of an external thread part and an internal thread part), height adjustment is attained with a simple structure. First, the height of the drain socket body outlet from the floor surface is determined by rotating the threaded portion, and then the base portion is rotated relative to the height adjusting member, so that an arbitrary position of the base portion is obtained. Can be fixed to the floor. Therefore, the pitch of the threaded portion can be made relatively large to withstand a large load that can be applied during construction. As a result, it is possible to achieve both the positioning of the pedestal portion on the floor surface and the positioning of the water distribution pipe and the drainage pipe of the flush toilet, while ensuring the strength.

In the present invention, preferably, the height adjusting member has a first tube portion having a first outer screw portion and a second inner screw portion screwed with the first outer screw portion of the first tube portion.

  Next, a first cylindrical portion 30 is formed integrally with the main body 22 at the lower portion of the drain socket main body 22. A second cylindrical portion 32 formed separately from the main body 22 is provided on the outer peripheral side of the first cylindrical portion 30, and further, the main body 22 and the second cylindrical portion 32 are provided on the outer peripheral side of the second cylindrical portion 32. A third cylindrical portion 34 formed separately from the cylindrical portion 32 is provided. A pedestal portion 36 is provided around the third cylindrical portion 34 so as to surround the third cylindrical portion 34.

Next, the configuration of each cylindrical portion will be described with reference to FIGS. FIG. 3 is a vertical cross-sectional view illustrating the configuration of the first cylindrical portion, the second cylindrical portion, and the third cylindrical portion in the first position according to the embodiment of the present invention.
As shown in FIGS. 2A and 3, a male screw portion (outer screw portion) 30 a is formed on the outer peripheral side of the first cylindrical portion 30. Then, on the inner peripheral side of the second cylindrical portion 32, a female screw portion (inner screw portion) 32a that is screwed with the male screw portion 30a is formed. Furthermore, an external thread portion (external thread portion) 32 b is formed on the outer peripheral side of the second cylindrical portion 32. Then, on the inner peripheral side of the third cylindrical portion 34, a female screw portion 34a (inner screw portion) that is screwed with the male screw portion 32b is formed. By these screw portions 30a, 32a, 32b, and 34a, the first cylindrical portion 30 and the second cylindrical portion 32 can rotate relative to each other and move in the vertical direction, and the second cylindrical portion 32 and the second cylindrical portion 32 The three cylindrical portions rotate relative to each other and can move in the vertical direction.

  The screw portion 30a of the first cylindrical portion 30 and the screw portion 32a of the second cylindrical portion 32 are formed at the same pitch, and the screw portion 32b of the second cylindrical portion 32 and the screw portion 34a of the third cylindrical portion 34 are also the same. It is formed with a pitch. On the other hand, the pitch between the screw portion 30a and the screw portion 32a is smaller than the pitch between the screw portion 32b and the screw portion 34a. For example, the pitch between the screw portion 30a and the screw portion 32a is 3 mm, and the pitch between the screw portion 32b and the screw portion 34a is 4 mm.

  And each pitch of these threaded portions 30a, 32a, 32b, 34a can sufficiently withstand the load of the flush toilet body 2 and the load generated when the flush toilet body 2 is installed in the drain socket 20, The pitch is relatively large. The outer diameter of the first cylindrical portion is 52 mm, and the outer diameter of the second cylindrical portion is 65 mm. Since the larger outer diameter is superior in strength, the outer diameter is set in consideration of storage of the drain socket 20 in the space inside the toilet body 2.

  In the present embodiment, the distance from the bottom surface of the pedestal portion 36 to the center of the cylindrical outlet portion 26 is 120 mm from the threaded portions 30a, 32a, 32b, 34a of the cylindrical portions 30, 32, 34. It changes to 155 mm. These states are shown in FIGS. FIG. 4A is a vertical cross-sectional view when the drainage socket of the flush toilet according to the embodiment of the present invention is in the second position, and FIG. 4B is the drain of the flush toilet according to the embodiment of the present invention. FIG. 5A is a side sectional view when the socket is in the second position, and FIG. 5A is a longitudinal sectional view when the drain socket of the flush toilet according to the embodiment of the present invention is in the third position. (B) is a side view when the drainage socket of the flush toilet according to the embodiment of the present invention is in the third position, and FIG. 6 is the first cylindrical portion at the third position according to the embodiment of the present invention. It is a longitudinal cross-sectional view which shows the structure of a 2nd cylindrical part and a 3rd cylindrical part.

  First, in the state shown in FIGS. 2 and 3, the second cylindrical portion 32 moves upward relative to the third cylindrical portion 34, and the first cylindrical portion 30 extends upward relative to the second cylindrical portion 32. (First position). In this state, since the distance from the bottom surface of the pedestal portion 36 to the center of the cylindrical outlet portion 26 is 155 mm, it is easy to adjust the height of the drain socket at the site where the drain core height is 155 mm. .

  Here, as shown in FIG. 3, a cylindrical portion 30 b is formed at the center of the first cylindrical portion 30, and a stopper 42 is attached to the bottom surface of the cylindrical portion 30 b by a tapping screw 40. In the first position as shown in FIG. 3, the stopper 42 hits the lowermost end portion 32 c of the screw portion 32 a of the second cylindrical portion 32, and the first cylindrical portion 30 is against the second cylindrical portion 32. It will not move upward any further. On the other hand, a flange portion 32e extending outward is formed at the lowermost end portion 32d of the second cylindrical portion 32, and this flange portion 32e is formed at the lowermost end portion 34b of the screw portion 34a of the third cylindrical portion 34. At the end, the second cylindrical portion 32 is prevented from moving further upward with respect to the third cylindrical portion 34. In this manner, a state is defined in which the second cylindrical portion 32 has moved upwards with respect to the third cylindrical portion 34 and the first cylindrical portion 30 has moved upwards with respect to the second cylindrical portion 32. The

  Next, the state shown in FIG. 4 is a state at an intermediate position where the distance from the bottom surface of the pedestal part 36 to the center of the cylindrical outlet part 26 is between 120 mm and 155 mm (second position). In the example shown in FIG. 4, the second cylindrical portion 32 moves to the uppermost position with respect to the third cylindrical portion 34, and the first cylindrical portion 30 is positioned at the lowermost position with respect to the second cylindrical portion 32. . On the other hand, for such an intermediate position, the second cylindrical portion 32 moves most downward with respect to the third cylindrical portion 34 and the first cylindrical portion 30 moves most upward with respect to the second cylindrical portion 32. You may make it do. Further, the second cylindrical portion 32 may move upward by a predetermined amount with respect to the third cylindrical portion 34, and the first cylindrical portion 30 may also move upward by a predetermined amount with respect to the second cylindrical portion 32.

Next, in the state shown in FIGS. 5 and 6, the first cylindrical portion 30 moves most downward with respect to the second cylindrical portion 32, and the second cylindrical portion 32 moves most with respect to the third cylindrical portion 34. It is in a state of moving downward (third position). In this state, since the distance from the bottom surface of the pedestal 36 to the center of the cylindrical outlet 26 is 120 mm, it is easy to adjust the height of the drain socket at the drain center height of 120 mm. .
Here, as shown in FIG. 6, a flange (stopper) 44 extending downward is formed on the bottom 28 of the drain socket body 22, and this flange 44 hits the upper end 34 c of the third cylindrical portion 34. The first cylindrical part 30 and the drain socket body 22 are prevented from moving further downward.

Next, the structure of the 3rd cylindrical part 34 and the base part 36 is demonstrated with reference to Fig.5 (a), FIG.7, and FIG.8. FIG. 7 is a perspective view of the pedestal portion according to the embodiment of the present invention as viewed obliquely from above, and FIG. 8 is a drain socket body, a first cylindrical portion, a second cylindrical portion, and a third cylinder according to the embodiment of the present invention. It is the perspective view which looked at the part from diagonally upward, and demonstrates a 3rd cylindrical part mainly here.
First, as shown in FIG. 7, the pedestal portion 36 is formed with an inner hole 36 d to be fitted into the third cylindrical portion 34. The pedestal portion 36 has a drain socket main body 22 (including the first cylindrical portion 30) shown in FIG. 8 removed from the second cylindrical portion 32 and the third cylindrical portion 34 from above the third cylindrical portion 34. 3 is fitted into the cylindrical portion 34 and is rotatable along the outer side surface 34d thereof.

  As shown in FIG. 8, a flange 34 e is formed on the lower edge of the third cylindrical portion 34 so as to extend sideways over the entire circumference. As shown in FIG. 5A (the same applies to FIGS. 2A and 4A), the lower edge portion of the inner hole 36d of the pedestal portion 36 is formed on the flange portion 34e of the third cylindrical portion 34. Thus, when the drain socket body 22 is lifted, the lower edge portion of the inner hole 36d of the pedestal portion 36 comes into contact with the flange portion 34e of the third cylindrical portion 34, and the pedestal portion 36 is prevented from being removed from the third cylindrical portion 34.

  Here, as shown in FIG. 7, a rib portion 36 f extending inward in the radial direction is formed at the lower edge portion of the inner hole 36 d of the pedestal portion 36. On the other hand, as shown in FIG. 8, the third cylindrical portion 34 is formed with a rib portion 34f that extends upward from the flange portion 34e and extends radially outward from the outer side surface 34d. Although illustration is omitted, similar rib portions are also formed on the opposite sides of these rib portions 36d and 34f by 180 degrees. When the pedestal portion 36 fitted to the outer side surface 34d of the third cylindrical portion 34 rotates, when the rib portion 36f comes into contact with the rib portion 34f, the pedestal portion 36 rotates the third cylindrical portion 34. I can do it. On the other hand, the pedestal portion 36 can freely rotate 180 degrees with respect to the third cylindrical portion 34 until the rib portion 36f contacts the rib portion 34f.

  Moreover, as shown in FIG. 7, the base part 36 is formed with two projecting parts 36a extending in the radial direction, and the base part 36 and the toilet bowl are fixed to the projecting parts 36a. A screw through hole 36c through which a screw for fixing 36 to the toilet floor F (see FIG. 1) passes, and a bolt hole 36b for supporting the bolt are formed.

  Next, with reference to FIGS. 2 and 9 to 12, a construction procedure for the wall surface W and the floor surface F of the drain socket 20 and a construction procedure for the drain socket 20 and the floor surface F of the flush toilet 1 will be described. FIG. 9 is a perspective view showing a construction process on the wall surface of the drain socket according to the embodiment of the present invention, and FIG. 10 is a perspective view showing a first half of the construction process on the floor surface of the drain socket according to the embodiment of the present invention. FIG. 11 is a perspective view showing the latter half of the construction process of the drain socket on the floor according to the embodiment of the present invention. FIG. 12 shows the construction process of the flush toilet on the drain socket according to the embodiment of the present invention. FIG.

  In the construction procedure, first, the pedestal portion 36 is rotated clockwise, and the first cylindrical portion 30, the second cylindrical portion 32, and the third cylindrical portion 34 are relatively shortest, that is, the above-described drawing. As shown in FIG. 5, the first cylindrical portion 30 moves downward relative to the second cylindrical portion 32, and the second cylindrical portion 32 moves downward relative to the third cylindrical portion 34 (first 3 position).

  Next, as shown in FIG. 9, the outlet portion 26 of the drain socket body 22 is connected to the inside of the pipe line D provided on the wall surface W. A cross-sectional view of the connected state is as shown in FIG. In this state, unlike FIG. 1, the pedestal 36 is separated from the floor F upward as shown in FIG. 9. The floor surface F is formed with four screw holes Fh in which screws passing through the screw through holes 36c of the projecting portion 36a of the pedestal portion 36 are fastened.

  Next, as shown in FIG. 10, the pedestal portion 36 is rotated counterclockwise as indicated by an arrow A, and the rib portion 36 f of the pedestal portion 36 is abutted against the rib portion 34 f of the third cylindrical portion 34. In this state, the third cylindrical portion 34 and the second cylindrical portion 32 are rotated. By such rotation, the first cylindrical portion 30, the second cylindrical portion 32, and the third cylindrical portion 34 extend in the vertical direction by the action of screws, and as a result, the cylindrical outlet port portion from the bottom surface of the pedestal portion 36. The distance to the center of 26 increases. Such rotation is performed until the pedestal portion 36 contacts the floor surface F. At this time, as shown in FIG. 10, the protruding portion 36a of the pedestal portion 36 is almost at a position deviated from the screw hole Fh on the floor surface.

Therefore, next, the projecting portion 36 of the pedestal portion 36 is positioned at the original position indicated by the phantom line in FIG. 10 (the position where the screw hole Fh and the screw hole 36c meet). In the present embodiment, if the rib portion 36f does not contact the rib portion 34f, the pedestal portion 36 is freely rotatable by 180 degrees with respect to the third cylindrical portion 34. Therefore, as shown in FIG. The pedestal portion 36 is rotated clockwise with respect to the floor surface as indicated by an arrow B, and the screw through hole 36c formed in the protruding portion 36a of the pedestal portion 36 is aligned with the screw hole Fh on the floor surface.
Next, as shown in FIG. 12, a screw is passed through the screw through hole 36c and screwed into the screw hole Fh. At that time, the head portion of the bolt B is simultaneously positioned in the bolt hole and supported by the pedestal portion 36 so that the bolt B faces upward. The bolt B may be fixed so as to penetrate the pedestal portion 36 upward from the lower surface portion of the pedestal portion 36.

  Here, as shown in FIG.1 and FIG.12, the string R is attached to the attachment surface 2b of the auxiliary machine 2a of the back side of the flush toilet 1. As the next construction procedure, as shown in FIG. 12, the installer holds the string R with one hand and also holds a part of the toilet, and slowly lowers the flush toilet 1. The outlet end 10 of the drainage channel 12 of the flush toilet 1 is aligned with the inlet 24 of the drainage socket 20, the mounting hole 2c of the flush toilet 1 is aligned with the bolt B supported by the pedestal 36, The center of the flush toilet 1 is aligned with the fixed piece Fs. The flush toilet 1 is fixed by fitting a nut N to a bolt B. Further, the outlet end 10 of the drainage channel 8 of the flush toilet 1 is firmly fixed to the inlet 24 of the drainage socket 20 by such nut tightening and the dead weight of the flush toilet.

Next, main effects of the present embodiment will be described.
First, in the present embodiment, the pitch of each screw portion 30a, 32a, 32b, 34a can sufficiently withstand the load of the flush toilet body 2 and the load generated when the flush toilet body 2 is installed in the drain socket 20, The pitch is relatively large. Therefore, the flush toilet 1 can be constructed more safely and without accidents.

  On the other hand, it is conceivable that when the threaded portion has a large pitch in this way, it is difficult to adjust the distance from the bottom surface of the pedestal portion 36 to the center of the cylindrical outlet portion 26. However, in the embodiment, the pitch between the screw portion 30a of the first cylindrical portion 30 and the screw portion 32a of the second cylindrical portion 32 is equal to the pitch of the screw portion 32b of the second cylindrical portion 32 and the screw portion 34a of the third cylindrical portion 34. It is getting smaller. Therefore, the distance from the bottom surface of the pedestal portion 36 to the center of the cylindrical outlet portion 26 can be easily adjusted to the distance from the floor surface F to the center of the pipe D. That is, the relative heights of the first to third cylindrical portions 30, 32, and 34 can be easily adjusted by rotating two screws having different pitches. Therefore, as described above, even if the pitch of the screw portions 30a, 32a, 32b, and 34a is relatively large in order to withstand a relatively large load, the center of the cylindrical outlet portion 26 is formed from the bottom surface of the pedestal portion 36. It becomes easy to adjust the distance.

  Furthermore, the screw by the screw part 30a of the first cylindrical part 30 and the screw part 32a of the second cylindrical part 32, the screw by the screw part 32b of the second cylindrical part 32 and the screw part 34a of the third cylindrical part 34, and the screw By providing two sets, the amount of movement due to the rotation of the screw, that is, the amount of up / down stroke can be made larger than in the case where there is only one set of screws. For example, assuming that the distance from the floor surface to the bottom surface of the drain socket is about 30 mm at the shortest, the height of the screw itself is set to 30 mm, and the remaining amount of the screws (the screws after the relative movement away from each other) If the height of the fitting is 10 mm, the screw moves only 20 mm when the screw is in one stage. On the other hand, when the screw has two stages, it moves as much as 40 mm. In the present embodiment, the stroke amount is ensured as described above, and the screw pitch is increased to sufficiently withstand the load.

  Next, in the present embodiment, when the pedestal portion 36 fitted to the outer side surface 34d of the third cylindrical portion 34 rotates, when the rib portion 36f contacts the rib portion 34f, the pedestal portion 36 causes the third cylinder to be in contact with the rib portion 34f. The part 34 can be rotated. Therefore, the relative heights of the first to third cylindrical portions 30, 32, 34 can be easily changed by simply turning the pedestal portion 36.

  Furthermore, as described above, when the threaded portion has a large pitch, it may be difficult to adjust the distance from the bottom surface of the pedestal portion 36 to the center of the cylindrical outlet portion 26. That is, if the pitch is small, even if the distance from the bottom surface of the pedestal portion 36 to the center of the cylindrical outlet portion 26 is slightly deviated, the seal portion 24a is crushed so that the outlet portion 26 is connected to the pipe D. Although it is possible, when the pitch is large, the collapse of the seal portion 24a may not be able to absorb the height error. However, in the present embodiment, the pedestal portion 36 is freely rotatable by 180 degrees with respect to the third cylindrical portion 34 until the rib portion 36f contacts the rib portion 34f. Therefore, at the time of construction, after adjusting the pedestal portion 36 to a height almost matching the floor surface F by the screw portions 30a, 32a, 32b, 34a, the pedestal portion 36 can be easily rotated by rotating with respect to the floor surface. The bolt through hole 36c of the pedestal portion 36 can be aligned with the bolt hole Fh on the floor surface.

  In the present embodiment, the screw pitch of the screw part 30a of the first cylindrical part 30 and the screw part 32a of the second cylindrical part 32, and the screw part 32b of the second cylindrical part 32 and the screw part 34a of the third cylindrical part 34 are shown. The screw pitch may be the same. In this case, after adjusting the pedestal 36 to a height substantially matching the floor surface F by the screw portions 30a, 32a, 32b, 34a, the pedestal 36 is rotated with respect to the floor surface, and the pedestal portion is thereby rotated. The 36 bolt through holes 36c may be aligned with the bolt holes Fh on the floor surface.

Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 13 (a) is a longitudinal sectional view in the case where the drainage socket of the flush toilet according to the second embodiment of the present invention is in the first position, and FIG. 13 (b) is according to the second embodiment of the present invention. It is a longitudinal cross-sectional view in case it exists in the 2nd position of the drain socket of a flush toilet. The second embodiment is the same as the first embodiment described above except for the configuration of the threaded portion. Here, the description of the same configuration as that of the first embodiment is omitted, and only different portions will be described.
As shown in FIG. 13, the drain socket 122 according to the second embodiment includes a first cylindrical portion 130 and a second cylindrical portion 132. The pedestal part 136 is rotated with respect to the second cylindrical part 132. Further, a male screw portion 130 a is formed on the outer peripheral side of the first cylindrical portion 130, and a female screw portion 132 a that is screwed with the male screw portion 30 a is formed on the inner peripheral side of the second cylindrical portion 132. Note that the ribs (not shown) are provided on the outer side surface 132d of the second cylindrical portion 132 and the inner hole 136d of the pedestal portion 136, as in the first embodiment.

  Therefore, by rotating the pedestal part 136 while abutting the rib part, the first position shown in FIG. 13A is changed to the first position shown in FIG. 13B by the action of the screw parts 130a and 132a. The second cylindrical portion 132 can be moved downward with respect to the first cylindrical portion 130 to the position of 2. And after height adjustment is complete | finished, the base part 136 can be rotated and the base part 136 can be set to a predetermined fixed position.
