DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faucet connection structure using header piping.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, piping connection of a hot water supply header for supplying hot water, a water supply header for supplying water, and a faucet 32 attached to a top plate 31 of a bathroom, a sink or a basin 30. The structure is a bellows-shaped sheath tube 35 connected to each header.
Is disposed under the floor 34, and a water pipe 36 made of a synthetic resin such as a polyethylene pipe is later inserted into the sheath pipe 35, and rises inside the cabinet 33. The joint part 37 is attached, and the faucet 32 has a connecting member 39 fixed to the tip of a connecting pipe 38 for introducing hot water and water extending downward, and the connecting member 39 and the joint part 37 are connected via a nipple 40 separately prepared. It is connected by a tool.

[0003] In the above-mentioned apparatus, a nipple which is a separate part is used to connect a water pipe inserted through a sheath pipe to a connecting pipe of a faucet, so that a tightening operation using a tool such as a spanner is required. The number of connection points is large, and the inside of the cabinet is narrow and work in an unreasonable posture is performed, so workability is poor, tools can not be operated well, insufficient nipple tightening and water leakage may occur due to construction mistakes And other problems.

[0004]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to reduce the number of parts required for connecting a faucet and a water pipe by a header pipe, and to make it easy and reliable for anyone even in a narrow place. The work time can be shortened and the workability can be improved.

[0005]

SUMMARY OF THE INVENTION According to the present invention,
A water pipe that is protected by being inserted through a sheath pipe placed under the floor and communicates with the hot water and water headers, and a connection that introduces hot water and water from a faucet attached to a top plate such as a bathroom, a sink, and a sink. In the pipe connection structure, a one-touch connection joint is attached to one of the water pipe and the connection pipe, and a joint directly connected to the joint is integrally formed on the other.

According to a second aspect of the present invention, the joint portion integrally houses functional parts such as a water stopcock, a check valve, and a strainer.

According to a third aspect of the present invention, the joint is a coupler-type socket.

According to a fourth aspect of the present invention, the joint and the connecting portion are connected by a quick fastener.

Embodiments of the present invention will be described below in detail with reference to the drawings. The present invention, as shown in FIG.
A sink or wash basin 1 is installed with a back surface along the wall 2, a faucet 3 composed of a hot and cold mixing faucet, a top plate 8 to which the faucet 3 is attached, and a cabinet 10 on which the top plate 8 is mounted, A wash bowl 11 fixed to the front surface of the top plate 8 is provided, and a drain port 12 is provided at the bottom of the wash bowl 11. It is discharged outside.

The water pipe 14 for hot and cold water is formed of a synthetic resin polyethylene pipe or the like which can be easily bent, and is pushed under a floor 16 into a bellows-shaped sheath pipe 19 provided in advance. Covered by a tube 19 and protected from the outside,
The upstream side is connected to each header (not shown) of hot water and water, and the downstream side is vertically bent toward the inside of the cabinet 10, passed through a fixing member 18 attached to an insertion hole 17 penetrating the floor 16, and A conventionally known coupler type joint portion 15 is mounted. In addition, a water stopcock,
A functional part 15b such as a check valve and a strainer is housed integrally.

The faucet 3 has a male screw 4 extending downward.
Is fixed to the top plate 8 by inserting a fixing nut 5 into the male screw portion 4 from the inside of the cabinet 10 below the top plate 8 through an attachment hole 9 formed in the top plate 8 from above. A hot water made of a material which can be easily bent such as resin or rubber and has excellent pressure resistance and heat resistance is provided at the lower portion of the male screw portion 4.
A connecting pipe 6 for water introduction is connected.

At the lower end of the connecting pipe 6, the water pipe 14
The joint 7 is formed integrally with the joint 15 and can be connected with one touch without using a tool. Accordingly, as shown in FIG. 2, the connecting portion 7 of the connecting pipe 6 and the water pipe 14
Can be directly connected, the connection work using a nipple using a conventional tool can be omitted, and the number of parts can be reduced, so that the cost can be reduced, and the number of connection points can be reduced. The reduction prevents construction errors in narrow places inside the cabinet and eliminates the risk of water leakage. Note that, contrary to the present embodiment, a joint may be attached to the connecting pipe, and the connecting part may be integrally formed in the water pipe.

FIG. 3 shows another embodiment. In this embodiment, the connecting pipe 6a and the water pipe 14a are connected by a quick fastener 20. The quick fastener 20 is formed by bending a metal plate into a substantially U-shape, and has a pair of slits 21 into which the joint 7a formed in the connecting pipe 6a and the joint 15a of the water pipe 14a are fitted. Therefore,
The distal end of the connecting pipe 6a is inserted into the joint 15a, and the quick fastener 20 is inserted between the slits 21 into the connecting portion 7a.
a and the coupling portion 15a are fitted, the connecting pipe 6a
And the water pipe 14a can be directly connected.

[0014]

According to the present invention, it is attached to a water pipe which is protected by being inserted through a sheath pipe disposed under the floor and communicates with a header of hot water or water, and a top plate such as a bathroom, a sink, a sink, and the like. In the connecting structure of a connecting pipe for introducing hot water and water from a faucet, a joint part for one-touch connection is attached to one of the water pipe or the connecting pipe, and a connecting part directly connected to the joint part is integrally formed on the other. Formed. Therefore, it is not necessary to connect a nipple between the joint and the joint as in the conventional case, and the cost can be reduced by reducing the number of parts. Connection can be reliably established in a short time even in a narrow place such as inside.

Further, functional parts such as a water stopcock, a check valve, and a strainer can be compactly stored in the joint part.

Further, since the joint and the connecting portion are connected by a coupler or a quick fastener when connecting the water pipe and the connecting pipe, there is no need to use a tool, and anyone can easily and surely use it in a narrow place such as inside a cabinet. Connection is possible, and there is no risk of water leakage due to construction errors.
