BACKGROUND OF THE INVENTION The present invention relates to a flexible resin pipe such as a polybutene pipe or a cross-linked polyethylene pipe (hereinafter referred to as "flexible resin pipe", which needs to be referred to in the claims and distinguish between the water side and the hot water side). Except for the case where there is an abbreviation, it is connected to a wall, and attached to a wall. An exposed type mixing faucet with an exposed functional part (hereinafter, it is necessary to clearly indicate that it is an exposed type,
Unless it is necessary to distinguish the hole type, it is abbreviated as a mixing faucet). In addition, the wall body here refers to any wall, counter, bathtub, or the like having a surface for installing a mixing faucet, and the surface for installing the mixing faucet is any of a vertical surface, a horizontal surface, and a slope. Regardless of whether the mixing faucet is a penetrating joint (hereinafter referred to as a penetrating joint, which connects the piping on the back side of the wall and the mixing faucet on the front side of the wall, The joints are abbreviated as joints, except when it is necessary to distinguish between them). The wall openings that penetrate the wall are provided separately on the water side and the hot water side, or are shared by one opening. It doesn't matter if it is a hole type.
Regarding the piping, it does not matter whether or not a sheath tube is inserted around and protected by the sheath.

[0002]

2. Description of the Related Art A) Conventionally, a mounting structure of a joint provided on a wall body for mounting and fixing a single faucet or a two-hole exposure type mixing faucet to the wall body is disclosed in Japanese Patent Application Laid-Open No. 63-142134, "Unit Bath" Temporary fixing structure of water faucet mounting box ", JP-A-9-152
A number of proposals have been made such as 058 "Fixed structure of the joint in the joint storage box", JP-A-10-72852 "Water faucet mounting device", and Japanese Patent Publication No. 6-56030 "Relay connector for fluid pipe piping". In any case, since the faucet is attached and fixed to the wall through the joint, the joint is also firmly attached and fixed to the wall and the supporting members of the wall.

B) On the other hand, in order to fix the mixing faucet body to a pair of water side and hot water side fittings fixed to a wall or the like, the core between the joints and the core on the inlet side of the mixing faucet body are required. In order to adjust the time, usually, as shown in FIG. 7, a pair of thermostat hot / cold water faucets with a wall, such as JIS B2061 “hydrants”, “Appendix 8 (Reference) Shape of faucets”, The joint and the mixing faucet main body 800 are connected via the connecting part 900 bent in a crank shape.

[0004] C) In order to eliminate the crank-shaped parts, Japanese Unexamined Patent Publication No. 9-3993 “Faucet attachment”, in order to obtain an accurate center-to-center dimension, joints are connected by a flange,
As disclosed in Japanese Patent No. 2695124, "a fixing structure of a faucet elbow for a hot and cold water mixing tap and a connecting structure of mounting legs", there is a device having a holding portion capable of adjusting an interval between joints.

D) Further, in the case of a one-hole type mixing faucet,
As in Japanese Patent Publication No. 5-14048, "Apparatus for supplying hot and cold water to a hot and cold water mixing tap" and Japanese Patent Application Laid-Open No. 11-36392, "Connecting structure of hot and cold water mixing tap" There is something that connects.

[0006]

In the joint mounting structure of A), since the joint is firmly attached and fixed to the wall or the supporting material of the wall, the distance between the cores of the pair of joints is completely fixed. Moreover, since the fitting and fixing work of the joint is also performed at the construction site, accuracy is difficult to obtain, so that the size of the center of the mixing faucet main body does not match the center distance of the mixing faucet main body, so that the fixing faucet main body cannot be fixed. It is likely to occur.

For this reason, as shown in B), the joint and the mixing faucet main body 8 are connected via the connecting part 900 bent in a crank shape.
However, the adjusting operation requires considerable skill, the possibility of water leakage is large, and a pair of connecting parts 900 between the wall and the mixing faucet main body 800 are connected. And the shape is complicated, cost,
There is a problem in terms of design and cleanability.

In order to solve this problem, C) has been proposed. In the former, however, a high degree of precision is required for both the distance between the core of the joint and the distance between the cores on the inlet side of the mixing faucet main body. However, there is a problem that the manufacturing cost is increased. In the latter case, the workability is improved by the easier adjustment of the center-to-center dimension of the joint than in the general A). It is necessary to precisely match the core distance with the core distance on the inlet side of the mixing faucet body in advance, and if this is forgotten or neglected, if it cannot turn to the back side of the wall, it will not be possible to apply it. There is a possibility.

In D), since the joints on the water side and the hot water side are integrated, dimensional play is difficult to take in connection with the inlet side of the mixing faucet main body, and high dimensional accuracy is required. There is a problem that construction is difficult and the cost is increased accordingly, and that there is a high possibility of water leakage due to poor manufacturing and construction accuracy.

In any of the above prior arts, the joint is fixed so as not to be rotatable, so that the degree of freedom in the pipe taking-out direction is limited and the pipe is bent or twisted due to a repulsive force or the like. In addition, there is a problem that it is difficult to mount and fix the joint in a predetermined direction, which causes an increase in construction cost.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to install a mixing faucet which is easy to manufacture, construct and inspect, and has a design, cleanability and a small possibility of water leakage. It is to provide a structure at a low cost.

The configuration of each part and the effect of this embodiment in each construction stage will be described while explaining the standard construction procedure of this embodiment. Note that the construction order and other points do not necessarily have to be the same.

A pair of pipes 1 for the water side and the hot water side are laid from the header (not shown) to the back side of the wall panel 4 and temporarily fixed to a waterproof floor pan (not shown) of the bathroom unit, and the like. The pipe 1 is connected to the inlet-side connecting portion 211 formed on the joint inlet side 21 of the joint 2, and the height of the joint outlet side 22 is higher than the mounting height of the faucet main body inlet side 81 of the mixing faucet main body 8. After roughly adjusting the position to a predetermined size, for example, several centimeters to several tens of centimeters, the pipe 1 is permanently fixed to a waterproof floor pan or the like. In this embodiment,
Since the inlet side connection part 211 is a one-touch connection type joint, it is securely connected and fixed only by inserting the pipe 1,
There is no risk of water leakage. In addition, since the inlet side connection part 211 is also a free-rotation type joint, it is easy to connect even if the pipe 1 has a bending habit or torsion, and even if the joint outlet side 22 faces a new direction, it takes time to correct it. Nor.

A wall backing material 3 is provided on the back side of the wall panel 4.
The wall surface patch 5 is applied to the front side, and the wall surface patch fixing screw 5

Is pressed against the wall covering material 5 via the retaining ring 62 and the joint plate 61 to restrict the movement of the joint rearward, so that there is no possibility that the joint 2 will escape backward in the following process. Also, the joint outlet side 22 is held so as to be rotatable around the axis, that is, the joint outlet side 21 can be held in any direction, so even if the pipe 1 is bent in the above-described process. Unlike the conventional example, it is not necessary to struggle to fix the joint inlet side 21 in a predetermined direction while countering the repulsive force of the pipe, and the work of holding the joint outlet side 22 in this step is extremely easy. is there. Since the work of holding the joint 2 is easy even when the pipe 1 is bent in this manner, in the above-described step, the position of the joint outlet side 22 is adjusted (the length of the pipe 1 is adjusted).
However, the work is easy because it can be rough, and it is also possible to connect the pipe 1 and the joint 2 instead of the above steps.

After the joint holding hole 632 formed inside the mounting seat body 631 of the faucet mounting seat (second holding member) 63 and the joint outlet side 22 are fitted, the seat fixing screw 639
Is screwed into the seat fixing screw hole 33 formed in the wall backing material 3 through the seat fixing hole 636, the seat fixing screw insertion hole 612, the wall opening 41 and the like, and the faucet mounting seat 63 is attached to the wall backing material. 3 and fix it. By this operation, the joint outlet side 22 is moved forward by the stopper 633 to prevent the joint holding hole 632 from moving forward.

In the present embodiment, the rear end outer surface of the faucet connecting pipe 71 and the front end inner surface of the connecting pipe connecting hole 221 are chamfered, and between the first cap nut 72 and the faucet connecting pipe 71, Since a predetermined play necessary and sufficient to absorb various assumed dimensional errors is provided, a pair of faucet connecting pipes 71 is provided at a distance between a pair of joint outlet sides 22 (more precisely, connecting pipe connecting holes 221). Since they move together, that is, they automatically adjust their intervals, insertion is easy.

While pressing the mixing faucet body 8 backward, the second cap nut 73 is screwed into the faucet fixing second screw 638 formed on the outer periphery of the mounting seat body 631 and sufficiently tightened. When the cap nut 72 is sufficiently tightened, the operation is completed. In this embodiment, since the O-ring 222 is provided inside the connection pipe connection hole 221, the joint 2, the faucet connection pipe 71, and the mixing faucet main body 8 are watertight by this simple operation. The connected faucet body 8 is firmly attached and fixed to the faucet mounting seat 63 via the faucet connecting member 7. Since the faucet mounting seat 63 is firmly attached and fixed to the wall panel 4 in the above process, the mixed faucet main body 8 is also firmly attached and fixed to the wall panel 4. Further, when the faucet connecting pipe 71 is inserted into the connecting pipe connecting hole 221, the on-off valve 223 built in the joint outlet side 22 opens, and when it is pulled out, the on-off valve 223 is closed. However, the mixing faucet body 8 can be attached and detached, and the construction time at the time of maintenance or the like can be reduced. In addition, do not close the main valve,
Even if the mixing faucet main body 8 is removed by mistake, hot water can be prevented from blowing out and developing into an accident.

As described above, in the installation structure of the mixing faucet of the present embodiment, the installation work of the mixing faucet including the pipe connection is performed before the wall panel 4 is built and the wall panel 4 after the wall panel 4 is built. Since all operations can be performed from the front side, there is no need to provide a space or a passage on the rear surface of the wall panel 4 where an operator can turn, or to provide an opening in the wall panel 4 for work. And can be securely fixed. Moreover,
Because of its small size and simple configuration and shape,
In all aspects of design, cleanability, and cost, not only can the problem of installing the mixing faucet be solved, but since all members are fixed from the front side of the wall panel 4, the faucet mounting is performed in the reverse order of the mounting process. If the seat 63 is removed, the joint 2 can be pulled forward while the pipe 1 is connected, so that inspection, repair, replacement, and the like in case of an emergency are easy. Of course, it is also very easy to replace the mixing faucet body 8 for improving the design and function.

FIG. 4 is a sectional exploded perspective view of a second embodiment in which the present invention is applied to a one-hole type mixing faucet to be attached to a wall panel of a bathroom unit, FIG. 5 is a front view of the second embodiment, and FIG. It is principal part sectional perspective view of 2nd Example.

The main differences between the present embodiment and the first embodiment are as follows, and the other parts are basically the same as those of the first embodiment. Will be described with the same reference numerals.

1) In contrast to the two-hole system of the first embodiment, the present embodiment has a one-hole system, that is, a system in which the water-side and hot-water-side joints pass through one hole.

2) In the first embodiment, the present invention is applied to a flexible resin piping system not using a sheath tube, but in the present embodiment, the present invention is applied to a flexible resin piping system using a sheath tube. Along with this, the wall backing material shall be a faucet box to which a sheath tube can be connected.

3) In the first embodiment, the connecting pipe fixing member is made of the first material.

In the present embodiment, the outer diameter of the wall covering material 5 is
The faucet box 34 is formed at a predetermined position on the back surface of the wall panel 4 by this simple operation because the wall covering member rib 54 projecting rearward, which is slightly smaller than the inner diameter of the wall panel 4, is formed. In addition, there is no packing for preventing rotation between the wall panel 4 and the wall covering member 5, and the wall covering member fixing screw 53 is not tightly tightened. By making the holding state rotatable,
It becomes easy to adjust the mounting angle of the mixing faucet body 8 in the following steps.

The pipe 1 is connected to an inlet-side connecting portion 211 formed on the joint inlet side 21 of the joint 2, and from the surface side of the wall panel 4, the wall covering material opening 51, the wall opening 41, and the faucet box outlet are provided. Side opening 342, faucet box entrance side opening 345
Through, the pipe 1 is inserted into the sheath tube 11 and the faucet box 3

Then, the stopper ring 62 is inserted into and locked in the concave groove 23, and the joint outlet side 22 is pressed rearward. In the present embodiment, the retaining ring 62 is a one-touch mounting type formed of an elastic material such as a metal or a resin.
It is very easy to insert and lock into. With this simple operation, the pair of joint outlet sides 22 are pressed at approximately predetermined intervals to the wall covering member 5 via the joint plate 61, and the backward movement is regulated. Thus, there is no possibility that the joint 2 escapes backward. In addition, since the pair of joint outlet sides 22 are arranged at a substantially necessary minimum interval from each other, it contributes to downsizing of the mixing faucet. Also, the joint outlet side 2
2 is held rotatably about the axis, that is, it can be held regardless of the direction of the joint inlet side 21, so that the faucet box inlet side opening 345 and the joint outlet side as in the present embodiment. 22 are arranged at substantially the minimum necessary intervals, the intervals between the two are not the same, and even if it is necessary to turn the joint inlet side 21 in an oblique direction, the joint inlet side 21 is opposed to the pipe repulsion force. It is not necessary to struggle to fix the joint in a predetermined direction, and the work of holding the joint outlet side 22 in this step is extremely easy.
