  As a low floor specification and barrier-free measure, the present invention includes a drainage port of a bathtub equipped with a remote-controlled drainage device whose height across the bathtub is as low as possible and a drainage port of a waterproof pan. The present invention relates to a drainage connection structure to be connected.

Conventionally, the height of the space between the bottom of the bathtub with a remote-operated drain plug device and the waterproof pan has been reduced as much as possible by the low floor specification due to high-rise apartments and barrier-free measures. There is a long-awaited drainage connection structure that suppresses the above.
The drainage connection structure of the drainage port of the bathtub and the drainage port of the waterproof pan equipped with the remote control type drainage device is equipped with a connection joint to which these are connected. In order to maintain watertightness when connecting the waterproof pan to the drain outlet, the connecting pipe is equipped with a technical tube (insertion section) through which the release wire that is transmitted to is inserted. An adjustment means (bellows-shaped cylinder) for absorbing the error is interposed.

  The joint is screwed into the drain fitting that penetrates the drain of the bathtub, the edge of the drain of the bathtub is sandwiched, and the lower end of the joint is smaller than the drain of the waterproof pan, and the inside of the drain is planar And a connecting drain pipe projecting so as to be movable in the vertical direction, and a flange having a diameter larger than the drain opening of the waterproof pan provided above the lower end of the connecting drain pipe. A drain outlet is closely attached in a watertight manner, and the position height of the flange is automatically adjusted, and such an adjusting means is provided (Patent Document 1).

  Moreover, the drainage connection structure of the drainage port of the bathtub and the drainage port of the waterproof pan forms a flange for attachment to the bathtub at the upper part of the cylindrical main body, and the soft member attached to the drainage port of the waterproof pan at the lower part ( Forms a ring-shaped joint (flange) that joins the bellows, and consists of a connection joint (direct drop nut) with the bottom surface of this joint as an inclined surface, and connects the drain of the bathtub to the drain of the waterproof pan At this time, the joint portion of the connection joint crushes the soft member attached to the drain of the waterproof pan to ensure water tightness (Patent Document 2).

The adjustment means provided with a connection drain pipe and interposed for water tightness makes the connection structure complicated and complicated, so that the connection construction is not easy and the repair after the construction is also lacking and inconvenient. It is.

In addition, a flange for attachment to the bathtub is formed on the upper part of the cylindrical body, and a ring-shaped joint having a lower surface that joins a soft member attached to the drain of the waterproof pan is formed on the lower part of the flange. In the drainage connection structure (Patent Document 2) composed of the connected joint, the connection joint has a simple structure, but the soft member attached to the drainage port of the waterproof pan is crushed to ensure water tightness. At the time of construction, the connection part of the connection joint must be aligned with the soft member in the state where the drainage connection structure is hidden behind the bathtub, and it moves in the plane direction and the vertical direction so that it adheres in a watertight manner. It is very difficult, time consuming and inconvenient.
In addition, this connection joint does not have an insertion part through which a release wire for transmitting remote operation to the drain plug is inserted, and is not provided between the joint part of the connection joint and the soft member attached to the drain of the waterproof pan. Pulling it out in a pinched state tends to create a gap there, hindering water tightness, and at the time of connecting the waterproof pan to the drainage port with a connection joint, the release wire obstructs the work. It is difficult.

  Therefore, in the drainage connection structure of the present invention, the connection joint that connects the drainage port of the bathtub and the drainage port of the waterproof pan clamps and fastens the bathtub with the drainage fitting provided to support the remotely operated drainage plug device.

It can be easily and easily screwed onto the bracket, and the downwardly facing outward flange can be easily attached with a soft packing, which makes the structure simple and watertight with the drain of the waterproof pan. The purpose is to be able to secure the property and to easily install.

  Furthermore, the height across the bathtub can be reduced as much as possible, and a branch pipe through which the release wire is inserted is formed only when the height is lowered, so that it does not hinder the insertion of the release wire directly into the nut. Objective.

  In the drainage connection structure of the present invention, the tub is placed on the waterproof pan, and the drainage of the bathtub is connected to the drainage port of the waterproof pan. The straight drop nuts fastened with the fittings make the straight cylindrical body vertically symmetric, form vertically symmetric outward flanges at the upper and lower ends, and form internal threads on the entire inner surface of the straight cylindrical body. The downward outward flange is provided with a soft packing that connects the downward outward flange and the drain of the waterproof pan.

  In the drainage connection structure of the present invention, a branch pipe through which a remote-controlled release wire is inserted is disposed at a vertically symmetrical intermediate position of a main body having a straight drop nut.

  In the drainage connection structure of the present invention, the branch nut is inserted through a remote-control-type release wire having a straight drop nut at a vertically symmetrical intermediate position of the straight cylindrical main body and on the cylindrical wall of the main body and whose axis is separated from the axis. A tube is provided.

  In the drainage connection structure of the present invention, the straight drop nut is arranged in a straight cylindrically symmetrical middle position, and a branch pipe through which the remotely operated release wire is inserted is arranged on the cylindrical wall of the main body, and the branch pipe is The shaft is on the cylinder wall tangent of the main body, and is a cochlea shape.

  In the drainage connection structure of the present invention, the bathtub is fastened with a vertically falling nut and a drainage fitting, and a soft packing that connects the drainage port of the waterproof pan is attached to the downwardly outward flange of the nut. The structure is simple, the number of parts is reduced, the assembly is simple and easy, and the watertightness can be ensured.

  And since the branch pipe which a remote control type release wire penetrates falls directly and exists in the intermediate position of a nut, it can attach easily without considering a drain outlet metal fitting at the time of fastening to a bathtub.

Remotely-operated release pipe for direct drop nut The branch pipe through which the release wire is inserted is arranged on the cylindrical wall of the direct drop nut body with its shaft removed from its axis, so the remote-operated type is supported by the drain fitting. The release wire that is dropped directly from the working part of the drain plug and inserted into the cylinder wall of the nut can be bent gently without bending, improving the remote control function of the release wire and improving durability. be able to.
In addition, the effect is further improved by arranging the branch pipe through which the remote-operated release wire is inserted so that its shaft is dropped directly on the tangent line of the cylinder wall of the nut body.
In addition, the branch pipe is directly dropped and disposed on the cylinder wall of the nut body with its shaft off the axis, or the branch pipe falls directly on the axis of the nut wall and is tangent to the cylinder wall of the nut body. By being arranged in this way, the arrangement direction of the branch pipes can be reversed by directly turning the nut downward. Therefore, the direction in which the release wire is inserted can be reversed.
