DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction structure of a mixing faucet with a wall, and more particularly to a construction structure which can be mounted without using a conventionally used crank leg.

[0002]

2. Description of the Related Art Conventionally, installation of a mixing faucet with a wall is performed by attaching a faucet body to a wall by a crank leg having a crank shape which also serves as a passage member for water and hot water. FIG. 6 shows an example.

[0003] In the figure, reference numeral 200 denotes a faucet main body, from which a spout tube 202 extends. 20
Reference numeral 4 denotes a crank leg, which is an externally threaded pipe 20 connected at one end to a water supply pipe and a hot water supply pipe constructed behind the wall 206.
8 and a connection port 212 connected to the connection port 210 of the faucet main body 200 on the other end side.

[0004] In the case of the construction of the mixing faucet of this example, the male screw pipes 208 of the pair of crank legs 204 are screwed and fixed to the water supply and hot water supply pipes, and the opposite connection port 212 is connected to the faucet. The faucet main body 200 is fixed to the wall 206 via the crank leg 204 by being screwed to the connection port 210 of the main body 200 with a cap nut. That is, the mixing faucet is attached and fixed to the wall 206.

In the construction structure of the mixing faucet using such a crank leg 204, the crank leg 204 is rotated around the axis of the male screw pipe 208, as shown in FIG. Each connection port 2 in 204
12 can be matched with the horizontal interval of the connection port 210 in the faucet main body 200. Therefore, the horizontal interval of the water supply and hot water supply pipes provided on the back side of the wall 206 is equal to the horizontal distance. Regardless, or regardless of the positional error of their arrangement, the faucet main body 200 can be satisfactorily connected to those pipes via the crank leg 204. That is, the mixing faucet can be satisfactorily attached to the wall 206 for construction.

By the way, in a bathroom unit or the like which has been widely used in recent years, when a mixing faucet is mounted on a wall such as a wall panel of the unit or a front plate of a counter, the faucet goes around the back side of the wall. Installation work can be performed, but in the case where a mixing faucet is installed on the skeleton wall of the building, for example, on the front wall of the kitchen, the other pipe is used for water supply or hot water supply as the building side pipe Because of the original piping and the wall is the skeleton wall, it is practically impossible to work around the back side of the wall when installing the faucet. Problems occur.

FIG. 8 shows a state in which a mixing faucet is attached to the inner surface of a wall 206 (in this example, a tile wall) which is a skeleton wall. In FIG. This is a main pipe for water supply and hot water supply as a building-side pipe, which has been set up on the back side of the wall 206 by a water supply contractor. The upper end of the main pipe 214 is generally constituted by an elbow 216, and a connection port 218 at the front end of the elbow 216 is formed as a socket, and a female screw portion 220 is formed on the inner peripheral surface thereof.

When the mixing faucet is attached to the wall 206, which is the frame wall, the faucet main body 200 is attached and fixed to the wall 206 via the crank leg 204, and the crank leg 204 is fixed to the original wall. A screw connection is made to the pipe 214, but the problem in this case is that the main pipe 21 for water supply is used.
4 and a hot water supply main pipe 214 are located at a position where they are drawn from the inner surface of the wall 206 to the back side, and the pair of connection ports 21
8 is drawn from the inner surface of the wall 206 to the original pipe 214 for water supply.
And the main pipe 214 for hot water supply.
The point is that it is not possible to work around the back of 06.

Therefore, conventionally, a waterworks contractor has prepared (constantly provided) various types of take-out sockets (joint pipes) 222 called so-called zarbos having different axial lengths and other dimensions and shapes. , And an appropriate one is selected and screwed into the connection port 218 of the original pipe 214.

The take-out socket 222 has a male screw tube 224 on the rear end side and a female screw tube 226 on the front end side. Pipe 224
The inner peripheral surface 232 has a hexagonal cross section, and a hexagon wrench 236 is inserted into the inner peripheral surface 232 so that it can be rotated.

By selecting an appropriate take-out socket 222 and screw-connecting it to the side of the main pipe 214, the thickness of the wall 206 is absorbed, and the direction of the connection port 218 in each main pipe 214, that is, the wall 206 Absorbs the positional deviation in the inward and outward directions to some extent,
The crank leg 204 is screwed into the connection port on the front end side of the connector 22, and the faucet main body 200 is attached and fixed to the wall 206.

[0012]

As described above, regardless of whether the mixing faucet is installed on a wall panel such as a bathroom unit or a wall such as a front plate of a counter, or installed on a building frame wall. Conventionally, the faucet body 200 is attached to the wall 206 with a pair of crank legs 204 and is connected to the pipe on the back side of the wall 206. When the faucet main body 200 is mounted on the wall 206, the faucet main body 200 protrudes greatly from the inner surface of the wall 206 to the indoor side by the depth of the crank leg 204.

Further, the shape of the crank leg 204 is inevitably a fixed shape and a complicated shape due to its function, and moreover, the crank leg 204 occupies a large part of the mixing faucet in terms of space. However, this is a factor that deteriorates the appearance of the mixing faucet. In addition, this crank leg 2
In 04, spots and other stains remaining after the detergent or the like dries easily tend to remain, and the crank leg 204 has a complicated shape.

In particular, when the mixing faucet is attached to the building frame wall, it is impossible to work around the wall 206, so that the crank leg 204 is attached to the wall 206 and connected to the original pipe 214. Was accompanied by great difficulties.

[0015]

The construction structure of the mixing faucet with a wall according to the present invention has been devised to solve such a problem. According to the first aspect of the present invention, there is provided a joint pipe having a male thread on at least one end outer peripheral surface with respect to each female thread at an end of a water supply pipe and a hot water supply pipe provided on the back side of a wall. A pair of connecting pipes for water and hot water for introducing water and hot water into the faucet body of the mixing faucet disposed on the inner surface of the wall, while being screw-connected from the inside of the wall through the through holes of the wall. The connecting pipe is provided on the main body of the faucet, one of the connecting pipes is constituted by a rigid pipe and fixedly provided on the main body of the faucet, and the other is constituted by a flexible pipe having a predetermined length. Is connected to each of the pair of joint pipes.

According to a second aspect of the present invention, in the first aspect, the connecting pipe made of the flexible pipe is connected to the faucet main body in a direction parallel to the wall.

According to a third aspect of the present invention, in any one of the first and second aspects, the wall is a building frame wall, and the pipe is a main pipe for water supply and hot water supply as a building-side pipe. It is characterized by.

According to a fourth aspect of the present invention, in any one of the first to third aspects, a support plate is fixed to an inner surface of the wall, and the faucet body is supported by the support plate. Is pressed against and fixed to the inner surface of the wall by a large-diameter portion provided in the joint pipe.

[0019]

As described above, according to the present invention, the joint pipe is screwed from the inside of the wall to the female screw at the end of the pipe on the back side of the wall through the through hole in the wall, and the water is connected inside the wall. A pair of connecting pipes provided on the faucet body are connected to the joint pipes, and one of the pair of connecting pipes is constituted by a rigid pipe and fixedly provided on the faucet body, and the other is flexible. According to the present invention, regardless of the horizontal spacing of the pipes, according to the present invention, the flexible pipes are connected to the joint pipes and are connected to the joint pipes. The pipes and the faucet body can be connected.

That is, by rotating and adjusting the angle of rotation of the crank legs as in the prior art, the interval between the connection ports on the faucet main body side of the pair of crank legs is changed to the interval between the connection ports on the faucet main body side. The faucet body and the pipe on the back side of the wall can be easily attached to the wall in a connected state without performing troublesome operations such as matching.

Further, in the present invention, a joint pipe is screwed into the pipe on the back side of the wall from the inside of the wall, and a connecting pipe is connected to the joint pipe. Even if the work is not performed or the work cannot be performed, the wall-mounted mixing faucet can be mounted on the wall without any trouble.

Therefore, the present invention is particularly effective when applied to a case where the wall is a building wall of a building and the pipe is a main pipe for water supply or hot water supply as a building side pipe. 3).

Further, according to the present invention, since there is no need to use a crank leg as in the prior art, the faucet body can be attached and fixed so as to be close to or in contact with the inner surface of the wall. It is possible to solve a problem such that the mixing faucet is greatly protruded from the inner surface to the indoor side, and at the same time, a problem that the appearance of the mixing faucet is impaired by the presence of the crank leg.

Incidentally, it is conceivable that both of the pair of connecting pipes are constituted by flexible pipes. However, in this case, each flexible pipe, that is, each connecting pipe becomes short, and the adjustment range of the position in the left-right direction in each connecting pipe becomes narrow. In addition, it becomes difficult to manage the connecting pipe made of a flexible pipe.

However, in the present invention, since only one of the pair of connecting pipes is formed by the flexible pipe, the flexible pipe can be formed to be long. The advantage that the adjustment range of the plug mounting position can be widened is obtained. In addition, since one connecting pipe is fixedly provided on the faucet body with a rigid pipe, by connecting and fixing the connecting pipe made of the rigid pipe to the pipe on the other side, the supporting force or fixing force for the faucet body is formed. Can be provided.

In the present invention, the connecting pipe made of a flexible pipe can be connected to the faucet body in a direction parallel to the wall (claim 2). By doing so, the front-rear dimension, that is, the depth dimension of the accommodation space for accommodating the connection pipe can be reduced, and the protrusion from the wall surface of the faucet main body toward the room can be further reduced.

In the present invention, the faucet main body may be fixed directly to the inner surface of the wall. According to claim 4, a support plate is fixed to the inner surface of the wall, and the faucet main body is fixed by the support plate. And the support plate is pressed against and fixed to the inner surface of the wall by the large diameter portion provided in the joint pipe. With this configuration, the faucet main body can be firmly fixed and held via the support plate, and the support plate is further fixed to the wall from the inner surface side of the wall by screwing the joint pipe into the pipe. be able to.

The connecting pipe 36 is entirely formed of a rigid pipe, and is fixedly provided on the faucet body 14.

The connection pipe 36 has an end on the wall 12 side connected to the joint pipe 30. Various connection structures can be adopted as the connection structure. In this example, FIG.
As shown in the figure, the outer peripheral surface of the connecting pipe 36 is used as a male fitting surface, while the inner peripheral surface of the joint pipe 30 is used as a female fitting surface, and the connecting pipe 36 is inserted therein. The O-rings 40 attached to the outer peripheral surface of the parts are connected so as to be slidable in the axial direction and fitted in a watertight manner. However, this is an example, and various connection structures such as connection using a screw-type connection tool can be made.

The other connecting pipe 38 on the water side is formed entirely of a flexible pipe, and the end on the side of the faucet main body 14 has a connecting section 42.
Is connected to the faucet body 14. The end of the connecting pipe 38 on the faucet main body 14 side is connected to the connecting portion 42 in a direction parallel to the wall 12.
