BACKGROUND OF THE INVENTION
The present invention relates to a connection structure between a drainage port of a toilet and a drainage pipe embedded in a floor, and more specifically, using a connection pipe device having a drainage socket part, a horizontal pipe part, and a connection part connected to the drainage pipe. The present invention relates to a connection between a drain outlet and a drain pipe.
[0002]
[Prior art and problems to be solved by the invention]
As a connecting structure between the toilet drain port and the drain pipe buried in the floor, a drain socket with an insertion port for inserting the drain port is attached and fixed to the floor in a connected state to the drain pipe buried in the floor. In the prior art, it is known that the drainage port is inserted and connected in a watertight manner to the insertion port portion of the drainage socket via a joint packing.
[0003]
By the way, when a toilet becomes old and is replaced with a new one, that is, when an existing toilet is remodeled to a new one, it often happens that the drain outlet of the new toilet and the position of the drainage pipe embedded in the floor do not match. obtain.
Normally, the upper end opening of the drainage pipe, that is, the end of the connection with the drainage outlet of the toilet is placed at a position of 305 to 540 mm from the rear wall of the toilet, and a new toilet is installed at an appropriate position. Sometimes the position of the drainage port is shifted to the front and back of the drainage pipe, and if you try to install a new toilet in accordance with the drainage pipe in this state, the toilet will not fit in the toilet room. Or the problem that usability worsens arises.
[0004]
In this case, it is not possible to install new toilets as they are, and in order to connect the toilet outlets and drainage pipes well, it is necessary to perform floor construction and newly install drainage pipes. .
However, this was a tough work, and this actually made it difficult to replace the toilet bowl with a new one.
[0005]
Therefore, as a method of joining the drainage port and drainage socket of the toilet bowl, this was placed on the relatively rear side of the toilet bowl, while extending from the drainage socket part and drainage socket part with an insertion port part for inserting the drainage port. It has a connecting part connected to the drain pipe and the connecting part connected to the drain pipe, and the horizontally drawn pipe part is assembled in a fitted state so as to be detachable with respect to the drain socket part and the connecting part. It has been proposed to connect the toilet outlet and the drainage pipe using the connecting pipe device of the form.

In the case of this connecting structure, the distance between the drain socket part and the connecting part can be adjusted by cutting the horizontal pipe part in the connecting pipe device to an appropriate length. Regardless of the position of the drain outlet and the position of the drain pipe, they can be connected well.
[0007]
The connecting structure between the toilet drain port and the drain pipe using this connecting pipe device is particularly suitable for renovation, but of course, this connecting structure can also be used for new construction.
[0008]
However, when this connection structure is applied to a new construction, if a joist floor structure happens to be located on the center line of the toilet bowl, it becomes an obstacle and the drainage pipe cannot be installed at the same location, so avoid that obstacle. Either drainage piping had to be installed on the right or left side of the toilet central line, or work to remove the floor structure from the toilet central line occurred.
That is, in the conventional connection structure using the above-described connecting pipe device, there is a problem in that it cannot be handled if there is an obstacle on the toilet central line, and the toilet outlet and the drain pipe cannot be connected well .
[0009]
[Means for Solving the Problems]

[0037]
Although the embodiment of the present invention has been described in detail above, this is merely an example.
For example, in the above example, the second connecting portion 34A and the first connecting portion 34B are rearranged so that the same connecting pipe device 26 can cope with drainage pipes 24 and 116 having different connection methods. Either the connection pipe device in which the first connection portion 34B is provided integrally with the horizontal draw pipe portion 32 or the connection pipe device in which the second connection portion 34A is provided integrally with the horizontal draw pipe portion 32 is selected. Thus, it is possible to connect the drain port 20 of the toilet 10 and the drain pipe 24 (116), and even in this case, it is possible to cope with two types of drain pipes 24 and 116 having different connection methods. It is.
[0038]
Further, in the above example, the position of the connecting portion 34A or 34B is made variable by making the horizontal drawing pipe portion 32 in the connecting pipe device 26 rotatable with respect to the fixing portion 48 of the drain socket portion 30. By configuring the entire or a part of the horizontal tube portion 32 with a flexible tube, the position of the connecting portion 34A or 34B can be made variable using the flexibility.
[0039]
In the above example, a drain pipe 24a made of a PVC pipe of VU75 and a drain pipe 24b made of a PVC pipe of VP75 are fitted to a first fitting surface 86 on the inner peripheral surface of the inner cylinder portion 80 as a fitting cylinder portion. In addition, the drain pipe 24c made of the PVC pipe of the VP100 and the drain pipe 24d made of the PVC pipe of the VU 100 are connected to the second fitting surface 88 on the outer peripheral surface of the inner cylinder portion 80 through the adapter ring 90 or 92. However, in some cases, the inner cylinder portion 80 is formed to have a larger diameter than the above example, and the outer peripheral surfaces of the drainage pipes 24c and 24d made of PVC pipes of VP100 and VU100 are used as the first fitting face 86. On the other hand, for drainage pipes 24a and 24b made of PVC pipes of VU75 and VP75, the first fitting surface 86 of the inner cylindrical portion 80 has a different diameter from that of the above example. In the range which does not deviate from the gist of the present invention, it is possible to connect the outer peripheral surface of the drain pipes 24a and 24b to the inner peripheral surface of the adapter ring. It can be configured in various modified forms.
