Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a drain pipe flange for mounting a flush toilet used to connect a flush toilet and a drain pipe.

<Prior Art> Conventionally, the above-mentioned drain pipe flange for attaching a flush toilet has been such as shown in FIG. 6, for example. In the figure, reference numeral 2 denotes a flush toilet mounting flange, which has a cylindrical part 4 made of synthetic resin and a flange-shaped part 6 made of synthetic resin integrally formed at the upper end of this cylindrical part 4. The lower end of the cylindrical part 4 is connected to a drain pipe 8, and the brim part 6 is connected to a floor surface 10 with screws (not shown), and is bolted to the lower part 14 of a Western-style flush toilet 12. 16 and a nut 18. Note that 20 is packing for preventing water leakage.

<Problems to be solved by the invention> In such a flange, it is necessary to provide the brim portion 6 with a certain degree of strength. In other words, if the tensile strength of the flanged portion 6 is weak, the nut 18 is required to connect the flanged portion 6 to the lower part 14 of the Western-style flush toilet 12.
When firmly tightened, the bolts 1 are tightened even though the flanged portion 6 is connected to the floor surface 10 by screws.
The portion where the flange 6 is inserted and the vicinity thereof are pulled upward, causing the flange 6 to be significantly deformed and causing water leakage. The easiest way to increase the strength of the flange 6 is to increase the thickness of the flange 6. However, in this method, the thickness of the flanged part 6 may be larger than the depth of the recess on the floor surface 10 side of the lower part 14 of the Western-style flush toilet 12. When combined with
A new problem arises in that a gap is created between the lower part 14 and the floor surface 10, making it unsightly. If you want it to be strong and not unsightly, the flanged part 6
In addition to increasing the thickness of the recess, it is possible to increase the depth of the recess in the Western-style flush toilet, but this depth is determined by the Japanese Industrial Standards and cannot be changed.

<Means for solving the problem> Therefore, it is desired to develop a drain pipe flange for mounting a flush toilet in which the flange has sufficient strength without increasing the thickness of the flange. The invention aims to provide such a flange.

Therefore, in this invention, in a flange having a flange-like part and a cylindrical part as described above, a reinforcing body is buried inside at least the part of the flange-like part where a hole for installing a flush toilet is bored. It is something. As an embodiment in which a reinforcing body is provided, there is one in which the reinforcing body is buried over the entire surface of the brim-like portion.

<Example> A first example is shown in FIGS. 1 and 2. In both figures, 22 is a cylindrical portion, and 24 is a collar portion. The cylindrical portion 22 and the brim portion 24 are integrally molded from synthetic resin. Four circular recesses 26 are formed in the brim portion 24 at 90° intervals, and a through hole 28 is bored in the center of each of these recesses 26. These recesses 26 and through holes 28 are such that the head of a screw (not shown) is placed in the recess 26, the leg is inserted into the through hole 28, and the flanged portion 24 is inserted into the recess 26 and the through hole 28. It is for fixing to the floor.

Two elongated holes 30, 30 are bored between the recesses 26. These long holes 30, 30 are connected to the flanged portion 2.
This is to connect the lower part of a Western-style flush toilet with bolts and nuts, similar to the conventional one shown in FIG. A reinforcing body 32 having an elongated hole similar to the elongated holes 30, 30 is embedded in the brim portion 24 so as to surround the elongated holes 30, 30. This reinforcing body 32 is made of stainless steel or brass.

A second embodiment is shown in FIG. The second embodiment is constructed in the same manner as the first embodiment, except that the reinforcing body 32a is extended so as to also reinforce the recesses 26, 26. Equivalent parts are given the same reference numerals and their explanations will be omitted.

A third embodiment is shown in FIG. In the third embodiment, while the first and second embodiments reinforced only the vicinity of the elongated hole 30, the entire surface of the brim 24 is reinforced. Therefore, from the flanged part 24,
A reinforcing body 32b, which is shaped like a small disk and has holes corresponding to the recesses 26 and the elongated holes 30 punched therearound, is embedded in the brim portion 24.

These first to third embodiments are also used in the same manner as the conventional one shown in FIG.

<Effects> As described above, according to this invention, since the reinforcing body is embedded in the brim so as to surround at least the periphery of the flush toilet mounting hole, the thickness of the brim is not increased. , can have sufficient strength. Therefore, even if the flanged part is connected to the bottom of the flush toilet with bolts and nuts, the flanged part will not be deformed and water will not leak, and the connection between the bottom of the flush toilet and the floor will be maintained. There are no gaps between them. Moreover, since the reinforcing body is buried within the flange, when connecting the flange to the lower part of the flush toilet, the reinforcing body can be placed on the top surface of the flange, or it can be attached to the floor using screws, etc. No fixing work is required, and the work of connecting the flange to the flush toilet can be done smoothly.
