Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
Inside of the wall of a 1-hole exposed-type mixing faucet with an exposed functional part (hereinafter abbreviated as a mixing faucet, unless it is necessary to specifically indicate that it is an exposed type or to distinguish it from a 2-hole type) The present invention relates to a mounting structure of a mixing faucet which can be detached from a wall surface side by previously installing pipes, support members, and the like on the back side of the wall body before construction. In addition, a wall body here is a wall,
It generally refers to counters, bathtubs, and the like having a surface for mounting a mixing faucet, and it does not matter whether the surface on which the mixing faucet is mounted is a vertical surface, a horizontal surface, or a slope. In addition, the one-hole type means that a through joint (hereinafter, abbreviated as a joint, except for the case where the claims are cited) that connects the pipe on the back side of the wall and the mixing faucet on the front side of the wall is used. It is not a two-hole type in which the wall openings are separately provided on the water side and the hot water side, but refers to a wall opening shared by one wall opening.

[0002]

2. Description of the Related Art Conventionally, pipes and supporting materials on the back side of a wall of a one-hole type exposed mixing faucet to be mounted on a wall are installed in advance before the wall is constructed, so that the front side of the wall can be obtained. The mounting structure of the mixing faucet that can be detached from
"Water supply device for hot and cold water mixing tap", JP-A-11-363
92 "Connection structure of hot and cold water mixing faucet" and the like.

[0003]

In the conventional structure for mounting a mixing faucet, the water side and hot water side joints (hot water supply joints, through metal fittings) are integrated, so that the connection with the mixing faucet main body is difficult. Dimensional escape is difficult, high dimensional accuracy is required, manufacturing and installation are difficult, resulting in increased costs, and there is a high possibility of water leakage accident due to poor manufacturing and installation accuracy. There is.

Further, since the joint is inevitably unable to rotate, there is no freedom in the direction in which the pipe is taken out, and the joint is fixed in a predetermined direction due to stress caused by bending or torsion of the pipe. However, there is also a problem that the construction cost is increased and the possibility of a water leakage accident caused by the inclination of the joint is large.

[0005] Furthermore, in the above-mentioned conventional mounting structure of a mixing faucet, no measures are taken to make the wall opening small, so that the wall opening is large and it is difficult to perform the opening operation, which not only increases the cost. Inevitably, the member that covers the wall opening becomes larger, which hinders downsizing of the mixing faucet,
There is a problem that the design is reduced and the cost is increased due to the increase in the size of the member.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide an easy-to-manufacture and construction, a small possibility of water leakage, a good design, and an inexpensive mixed water. It is an object of the present invention to provide a plug mounting structure.

[0007]

Means for solving the above-mentioned problems in the mounting structure of the mixing faucet of the present invention will be described.

[0008] In the mounting structure of the mixing faucet according to the first aspect,
A circular wall opening formed in the wall, wall surface members and wall back members provided on both sides of the wall across the wall opening, a through joint penetrating the wall opening, and a substantially cylindrical joint outlet of the through joint In the connection structure of the mixing faucet having the mixing faucet body connected and connected to the side, in order to achieve the object of the present invention, the water-side and hot-water-side penetrating joints are separate parts, and the wall surface member and the backside of the wall are provided. At least one of the members holds the joint outlet side, and the diameter of the wall opening is slightly larger than the sum of the diameters of the pair of joint outlet sides, and the portion other than the area occupied by the joint outlet side in the wall opening is inserted. With the connecting member, the wall surface member and the wall back member were connected. The term “substantially cylindrical” used herein includes not only a cylinder having a uniform diameter inside and outside, but also includes, for example, an inner surface and / or an outer surface provided with irregularities in an arbitrary direction and a taper in a front-rear direction. .

That is, first, in order to solve the problem of the prior art in which the water-side and hot-water-side joints are integrated, the water-side and hot-water-side penetrating joints are separated from each other, and At least one of the wall back members held the joint outlet side. The wall surface member and the wall back member referred to herein are, for example, sandwiching the wall body therebetween, and distributing a load applied to the mixing faucet to the wall body to secure the mounting strength, for the purpose of securing the mounting strength, the front side and the back side of the wall body. A member or the like provided on the side, which is not necessarily limited to one member on each side, and may be several members. In addition, holding is not completely fixed, it may move a little if necessary,
This means to support the robot so that it can rotate around its axis. Therefore, dimensional relief is easy to take off, and high dimensional accuracy is not required, which makes manufacturing and mounting work easier, reducing costs and reducing the possibility of water leakage accidents due to poor manufacturing and construction accuracy. Further, since the degree of freedom in the pipe taking-out direction can be ensured, and the stress due to bending or torsion of the pipe is released, the work of mounting and fixing the joint in a predetermined direction becomes easy, and the force for tilting the joint outlet side is also reduced. As a result, the construction cost can be reduced and the possibility of a water leakage accident due to the inclination of the joint outlet side can be reduced. As described in detail in the embodiment of the invention, since the joint outlet side is rotatable around the axis, it becomes easy to adjust the position of the joint by bending the pipe, so that the pipe length is strictly set. There is no need for adjustment, and this point also has a great effect on improving workability.

[0010] Next, in order to solve the problem associated with the prior art that there is no contrivance for reducing the wall opening, the diameter of the wall opening must be slightly larger than the sum of the diameters of the pair of joint outlet sides. And Here, a slightly larger one is a relief size necessary and sufficient to absorb various dimensional errors,
For example, it means that the diameter is obtained by adding one to several millimeters. Since the opening is almost the minimum necessary and is circular, opening work is easy and cost reduction can be achieved, and the member that covers the wall opening can be smaller than the conventional technology, so that the design is improved and the cost is reduced. Can be achieved. Further, the wall surface member and the wall back member were connected by a connecting member that penetrated a portion other than a region occupied by the joint outlet side in the wall opening. When a pair of substantially cylindrical joint outlet sides are arranged in a circular wall opening, an area not occupied by the joint outlet side is always created, but this portion is effectively used as a connecting means between the wall surface member and the wall back member. By using, it is not necessary to enlarge the wall opening for the connecting means, and it is not necessary to make the opening operation difficult or to increase the size of the member that covers the wall opening to adversely affect the cost and design.

[0011] In the mounting structure of the mixing faucet according to claim 2,
In order to more effectively use the area not occupied by the joint outlet side described in the description of claim 1, the wall surface member and / or the wall back member does not interfere with the joint outlet side and the connecting member, and is substantially located at the wall opening. Positioning means was provided at the inscribed position. Therefore, since it is not necessary to enlarge the wall opening for the positioning means, it is not necessary to make the opening work difficult or to increase the size of the member for covering the wall opening so as not to adversely affect the cost and the design. If the positioning means is provided on both the member and the wall backing member, the two can be naturally set in a substantially predetermined position, thereby facilitating the connection work between the two. Further, even when the positioning means is provided on one side, since both of them are located at a substantially predetermined position by the connection, in any case, the mixing faucet body attached and fixed to the wall surface member and / or the wall back member naturally also has It can be placed in a substantially predetermined position, and the construction cost can be reduced without taking time and effort for positioning and without making the wall opening large.

According to a third aspect of the present invention, there is provided a mixing faucet mounting structure.
In order to provide the positioning means effectively and inexpensively, the projection is formed to protrude toward the wall opening side. The projections here include not only small circles, polygons, rectangles, and short linear shapes as viewed from the front, but also relatively long linear shapes such as arc-shaped ribs. Therefore, the structure is simple, and the metal member can be easily formed integrally into an effective shape by, for example, press molding, and the resin member can be formed by, for example, injection molding. Therefore, the cost can be reduced.

[0013] In the mounting structure of the mixing faucet according to claim 4,
When the positioning means is provided on both the wall surface member and the wall back member, the two projections are arranged so as not to overlap in a front view. Thereby, even when the wall is thin, there is no fear that both projections collide and the wall cannot be sufficiently fastened and fixed.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. In this description, “front” indicates a direction toward the surface of the wall panel (wall), and “back” indicates a direction toward the back of the wall panel.

FIG. 1 is an exploded perspective view in cross section of a first embodiment in which the present invention is applied to a one-hole type exposed mixing faucet to be attached to a wall panel of a bathroom unit, and FIG. 2 is a first embodiment (and a second embodiment). FIG. 3 is a cross-sectional perspective view of an essential part of the first embodiment.
1 is a pipe, 2 is a joint (penetrating joint), 3 is a wall backing material (wall back member), 4 is a wall panel (wall body), 5 is a rearward movement regulating member (wall surface member), and 6 is a faucet attachment. A seat (wall surface member), 7 is a faucet connection fixing member, and 8 is a mixing faucet main body.

The construction of each part and the features 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, water side and hot side, are laid and temporarily fixed to a waterproof floor pan (not shown) or the like of the bathroom unit, and an inlet side connection portion 2 formed at a joint inlet side 21 of the joint 2.
11 and the pipe 1 are connected, and the position is roughly adjusted so that the heights of the pair of joints 2 are substantially equal.

In this embodiment, the pipe 1 is a flexible resin pipe, and the inlet-side connecting part 211 is a one-touch connection type and free rotation type connection joint.

The wall backing material (wall backing member) 3 is formed together with the wall backing material main body 31, and is formed into a wall backing holding material 32 serving to hold the joint outlet side 22 to the wall backing material main body 31. A pair of joint outlets 22 are passed through one wall back holding material opening 321 to form a joint holding portion 32 formed on the wall back holding material 32.
2 is fitted into the groove 23 formed on the joint outlet side 22.

A pair of joint outlet sides 22 are inserted into one wall backing material opening 311 formed in the wall backing material main body 31,
The nail 323 formed on the wall backing material 32 is
11 and locked.

In this embodiment, since the wall back holding member 32 is made of a semi-hard resin, the front end of the claw 323 has an inclined surface, and the rear portion has a hook shape. The locking is easy, but the wall back holding material 32 has a grip portion 3.
Since the portion 24 is formed, if the claw 323 is bent inward by grasping this portion, the insertion and locking can be more easily performed. With this simple operation, the pair of joint outlet sides 22
The wall backing material 3 is held at substantially predetermined intervals and loosely integrated. Also, the joint outlet side 22 is held so as to be rotatable around its axis, that is, the joint outlet side 21 can be held in any direction, so that the piping 1 has a bending habit or twist. However, unlike the related art, there is no need to struggle to fix the joint inlet side 21 in a predetermined direction while countering the repulsive force of the pipe 1, and the holding work of the joint outlet side 22 in this step is extremely easy. It is.

The pipe 1 is adjusted to be slightly longer than the case where the position of the pair of joint outlet sides 22 is adjusted to the position of one wall opening 41 formed in the wall panel 4, and the pipe 1 is placed in a bathroom. The unit is permanently fixed to a waterproof floor pan or the like, the wall panel 4 is built, and the joint outlet side 22 is pulled out from the wall opening 41 forward.

The wall opening 41 connects the pair of joint outlet sides 22 with each other.
Substantially circumscribed circles when arranged at a minimum necessary interval from each other,
That is, since the opening is substantially the minimum necessary, it contributes to downsizing of the mixing faucet. Also, the joint outlet side 22 is held so as to be rotatable around its axis, and since the pipe 1 is a flexible resin pipe, if the pipe 1 is adjusted to be slightly longer,
As the joint outlet side 22 rotates around its axis, the pipe 1 is easily bent, and it is easy to pull the joint outlet side 22 in accordance with the position of the wall opening 41. The circumcircle of the three wall backing material projections (positioning means) 312 formed on the wall backing material main body 31 is slightly smaller than the wall opening 41, so that even if there are various errors, the wall can be reliably secured. Since it fits in the opening 41 and does not largely shift, the connecting work with the faucet mounting seat (wall surface member) 6 described later is facilitated, and the mixed faucet body 8 attached and fixed to the faucet mounting seat 6 is provided. Eliminates the need for positioning work. Further, the wall backing material projection 312
Is provided at a position where it does not interfere with the joint outlet side 22 and the seat fixing screw (connection means) 63 described later among the minimum wall openings 41, so that it is not necessary to enlarge the wall openings 41 for positioning means. This contributes to preventing the mixing faucet from becoming large.

The joint insertion hole 511 of the joint plate 51 constituting the rearward movement restricting member (wall surface member) 5 together with the retaining ring 52 is fitted until the concave groove 23 formed on the joint outlet side 22 is sufficiently exposed. , The retaining ring 52 into the groove 2
3 and press the joint outlet side 22 rearward.

In this embodiment, since the retaining ring 52 is a one-touch mounting type snap ring formed of an elastic material such as metal or resin, it can be easily inserted into and locked in the concave groove 23. With this simple operation, the pair of joint outlet sides 22 are pressed against the wall panel 4 via the retaining ring 52 and the joint plate 51, that is, the rearward movement restricting member 5, and the rearward movement is restricted. In the following process, there is no possibility that the joint 2 escapes backward. In addition, since the joint outlet side 22 can be held regardless of the direction of the joint inlet side 21 in the same manner as in the above process, there is no problem even if the pipe 1 is bent in the above process. In this step, a pair of joint outlet sides 2
Since the degree of parallelism 2 and the degree of perpendicularity to the surface of the wall panel 4 increase, the work of the following steps is facilitated.

A pair of joint holding holes 62 formed inside the mounting seat body 61 of the faucet mounting seat 6 and a pair of joint outlet sides 22
Then, the seat fixing screw (connection member) 63 is
The seat fixing screw hole 3 formed in the wall backing material main body 31 through the seat fixing hole 64, the seat fixing screw insertion hole 513, and the wall opening 41.
13 and temporarily fix the faucet mounting seat 6 to such an extent that the faucet mounting seat 6 does not move easily but can be rotated by applying force.

By this operation, the pair of joint outlet sides 22
Is restricted from moving forward by the stopper 65 and from moving in directions other than the front and rear by the joint holding holes 62, and further increases the degree of parallelism and the degree of perpendicularity to the surface of the wall panel 4 in the following steps. The faucet connecting pipe 71 can be easily inserted. In the present embodiment, the joint outlet side 22 is rotatable around its axis, similarly to the above-described step, so that the holding operation in this step is extremely easy regardless of the orientation of the joint inlet side 21. Note that the circumscribed circle of the three joint plate projections (positioning means) 512 formed on the joint plate 51 is slightly smaller than the wall opening 41 similarly to the wall backing material projection 312, so that there are various errors. Can be securely accommodated in the wall opening 41 and not greatly displaced, so that the connection work between the faucet mounting seat 6 and the wall backing material main body 31 performed through the seat fixing screw insertion hole 513 of the joint plate 51 can be easily performed. In addition, the positioning operation of the mixing faucet body 8 attached and fixed to the faucet attachment seat 6 becomes unnecessary. In addition, the joint plate projections 512 are the wall backing material projections 312.
In the same manner as described above, the joint outlet side 2
2 and at a position that does not interfere with the seat fixing screw 63,
It is not necessary to enlarge the wall opening 41 for the positioning means, which contributes to preventing the mixing faucet from becoming large. In addition,
The positions of the wall backing material projections 312 and the joint plate projections 512 are arranged so as not to overlap in a front view, so that even when the wall panel 4 is thin, both projections collide and sufficiently squeeze the wall. There is no loss of fastening.

A pair of straight tubular faucet connecting pipes 71, which together with the cap nut 72 and are attached to and fixed to the faucet main body inlet side 81 of the mixed faucet body 8 with the cap nut 72, constitute the faucet connecting and fixing member 7. After fully inserting into the connecting pipe connection hole 221 provided on the joint outlet side 22 through a pair of connecting pipe insertion holes 66 provided in the faucet mounting seat 6, the mixing faucet main body 8 is rotated left and right to mount. Adjust the angle.

In this embodiment, the outer surface of the rear end of the faucet connecting pipe 71 and the inner surface of the front end of the connecting pipe connecting hole 221 are chamfered, so that the joint outlet side 22 and the joint holding hole 62 held in the above-described steps are formed. A predetermined play required and sufficient to absorb various assumed dimensional errors is provided between them, so that the pair of joint outlet sides 22 move in accordance with the interval between the pair of faucet connecting pipes 71, that is, The insertion is easy because it automatically adjusts its own interval.

The mixing faucet main body 8 is once removed, and the seat fixing screw 63 is sufficiently tightened.

By this operation, the faucet mounting seat 6 is composed of the flange 67 formed on the rear outer peripheral portion of the mounting seat main body 61 and the wall backing material main body 31 which also plays a role of load distribution.
Is firmly attached and fixed. 68 is
This packing is attached to the back surface of the flange 67 to ensure the watertightness of the faucet mounting portion.

Again, the faucet connecting pipe 71 fixed to the mixing faucet main body 8 is inserted into the connecting pipe connecting hole 221, and the faucet main body of the mixing faucet main body 8 is pressed while pushing the mixing faucet main body 8 backward. The female screw 721 of the cap nut 72 held on the side 81 by the holding plate 711 is screwed into the faucet fixing screw 69 formed on the faucet mounting seat 6 and fully tightened.

In this embodiment, since the O-ring 222 is provided inside the connecting pipe connection hole 221, the joint outlet side 22, the faucet connecting pipe 71,
The mixing faucet body 8 is connected in a watertight manner, and the mixing faucet body 8 is firmly attached and fixed to the faucet mounting seat 6 via the cap nut 72. , Since it is firmly attached and fixed to the wall panel 4,
Are firmly attached and fixed to the wall panel 4. In addition, the joint outlet side 22 can adjust the interval, and
Since it is held so as to be rotatable around its axis, the pair of joint outlet sides 22 move in accordance with the distance between the pair of faucet connecting pipes 71 and most of the stress due to bending or twisting of the pipe 1. Is released and the force for inclining the joint outlet side 22 is reduced, so that the possibility of a water leakage accident due to a one-sided contact between the faucet connecting pipe 71 and the O-ring 222 is greatly reduced. Reference numeral 223 denotes an on-off valve that opens when the faucet connecting pipe 71 is inserted into the connecting pipe connecting hole 221 and closes when the faucet connecting pipe 71 is pulled out.

FIG. 4 is an exploded perspective view in cross section of a second embodiment in which the present invention is applied to a one-hole exposure type mixing faucet to be attached to a wall panel of a bathroom unit, and FIG. 5 is a faucet mounting seat of the second embodiment. FIG. 2 is a perspective view of the device viewed from the back side. The front view of the second embodiment is the same as the front view of the first embodiment, and the reference numerals are basically the same as those of the first embodiment. The front member) is a member in which the functions of the faucet mounting seat 6 and the joint plate 51 of the first embodiment are integrated.

As in the case of the first embodiment, the configuration of each part and the features of the present embodiment in each construction stage will be described while describing the standard construction procedure of this embodiment.

According to the first embodiment. However, the number of the faucet mounting seat (wall surface member) is 9, and the seat fixing screw (connecting member)
Is read as 93.

Seat substrate 90 of faucet mounting seat (wall surface member) 9
The fitting insertion hole 91 formed on the fitting outlet side 22 is fitted to the fitting outlet side 22, and a seat rib (positioning means) 96 formed on the back surface of the seat substrate 90 is fitted into the wall opening 41, and the recess formed on the fitting outlet side 22. The groove 23 is exposed in front of the seat substrate 90, the retaining ring 92 is inserted and locked in the concave groove 23, and the seat fixing screw (connecting means) 93 is inserted through the seat fixing hole 94 and the wall opening 41, and the wall backing material is The faucet mounting seat 9 is screwed into the seat fixing screw hole 313 formed in the main body 31 to temporarily fix the faucet mounting seat 9 so that the faucet mounting seat 9 cannot be easily moved but can be rotated by applying force, and the joint outlet side 22 is pressed backward.

The seat rib 96 is an arc-shaped projection whose left and right portions are cut so as not to interfere with the joint outlet side 22. Since the outer surface diameter is slightly smaller than the diameter of the wall opening 41,
Even if there are various kinds of errors, the mixed water can be securely fitted into the wall opening 41 and not greatly displaced. The operation of positioning the plug body 8 is not required. Moreover, the joint outlet side 22 and the seat fixing screw (connection member) 93
It is not necessary to enlarge the wall opening 41 for the positioning means, which contributes to preventing the mixing faucet from being enlarged. In this embodiment,
Claim 4 does not apply because it is not necessary due to the assumed thickness of the wall panel 4, but if necessary,
By making the portion that overlaps with the wall backing material projection 312 in a front view a cutout shape, it is possible to easily cope with it. or,
Since the retaining ring 92 is a one-touch mounting type snap ring formed of an elastic material such as metal or resin, it can be easily inserted and locked into the concave groove 23. With this simple operation, the pair of joint outlet sides 22 are connected to the wall panel 4 via the seat substrate 90.
To prevent the joint 2 from escaping rearward in the following process, and the pair of joint outlet sides 22 are substantially mutually minimum by the joint insertion holes 91. Since the parallelism and the verticality with respect to the wall panel 4 are increased while being held at intervals, the work of the following steps is facilitated and the mixing faucet is reduced in size. In addition, since the joint outlet side 22 can be held regardless of the direction of the joint inlet side 21 in the same manner as in the above step, there is no problem even if the pipe 1 is bent in the above step.

A pair of straight tubular faucet connecting pipes 71, which together with the cap nut 72 are fixed to the faucet main body inlet side 81 of the mixing faucet main body 81 by the holding plate 711, constitute the faucet connecting and fixing member 7. After sufficient insertion into the connection pipe connection hole 221 provided on the joint outlet side 22, the mixing faucet body 8 is rotated left and right to adjust the mounting angle.

Also in this embodiment, the outer surface of the rear end of the faucet connecting pipe 71 and the inner surface of the front end of the connecting pipe connecting hole 221 are chamfered. A predetermined play required and sufficient to absorb various assumed dimensional errors is provided between them, so that the pair of joint outlet sides 22 move in accordance with the interval between the pair of faucet connecting pipes 71, that is, The insertion is easy because it automatically adjusts its own interval.

The mixing faucet body 8 is once removed, and the seat fixing screw 93 is sufficiently tightened.

By this operation, the faucet mounting seat 9 is firmly mounted and fixed by sandwiching the wall panel 4 between the seat substrate 90 and the wall backing material main body 31 which also plays a role of load distribution. Reference numeral 97 denotes a packing attached to the rear surface of the outer periphery of the seat substrate 90 in order to ensure watertightness of the faucet mounting portion.

Again, the faucet connecting pipe 71 fixed to the mixing faucet main body 8 is inserted into the connecting pipe connecting hole 221, and the faucet main body of the mixing faucet main body 8 is pressed while pressing the mixing faucet main body 8 backward. The female screw 721 of the cap nut 72 held on the side 81 by the holding plate 711 is screwed into the faucet fixing screw 98 formed on the faucet mounting seat 9, and is fully tightened.

Also in this embodiment, an O-ring (not shown) is provided inside the connecting pipe connection hole 221 as in the first embodiment. 22, the faucet connecting pipe 71 and the mixing faucet main body 8 are connected in a watertight manner, and the pressing plate 711 on the mixing faucet main body 8 side is pressed against the contact surface 95 formed on the faucet mounting seat 9. The mixing faucet body 8 is firmly attached and fixed to the faucet attachment seat 9, and the faucet attachment seat 9 is firmly attached and fixed to the wall panel 4 in the above process. The panel 4 is firmly attached and fixed. In order to further secure the fixing between the mixing faucet main body 8 and the faucet mounting seat 9, means for preventing the pressing plate 711 and the contact surface 95 from slipping, for example, providing dowels and dowel holes, friction coefficient May be taken, or a spacer having a large coefficient of friction may be sandwiched or attached. In addition, the joint outlet side 22 can adjust the interval, and
Since it is held so as to be rotatable around its axis, the pair of joint outlet sides 22 move in accordance with the distance between the pair of faucet connecting pipes 71 and most of the stress due to bending or twisting of the pipe 1. Of the faucet connecting pipe 71 and an O-ring (not shown) provided inside the connecting pipe connecting hole 221 in combination with the fact that the force for tilting the joint outlet side 22 is reduced. The possibility of water leakage accidents due to hits etc. is also drastically reduced.

In the first embodiment, the joint outlet side is a wall backing member 3, which is a wall backing member, a rearward movement restricting member 5, which is a wall surface member, and a faucet mounting seat, which is also a wall surface member. 6, in the second embodiment, it is held by the wall backing material 3 and the faucet mounting seat 9, which is a wall surface member, but it is not always necessary to hold it by a plurality of members, and it is held by one member. Is also good. In the first embodiment, the positioning means is attached to the wall backing member 3 as the wall backing member and the rearward movement regulating member 5 as the wall surface member. Faucet mounting seat 9 as a member
However, even when claim 2 is applied, it is not always necessary to provide it on both the wall surface member and the wall back member, and it may be provided on only one of them.

According to the present invention, the following effects are exhibited by the above configuration.

In the mounting structure of the mixing faucet according to the first aspect,
First, the water-side and hot-water-side penetrating joints are separate parts, and at least one of the wall surface member and the wall back member holds the joint outlet side, so dimensional relief is easy to take, and high dimensional accuracy is not required This makes production and installation easier, reduces costs and reduces the possibility of water leaks due to poor production and construction accuracy, and also ensures flexibility in the direction in which the pipes are taken out, and also makes the pipes bend. Since the stress due to strain and torsion is released, the work of mounting and fixing the joint in a predetermined direction becomes easy, and the force for tilting the joint outlet side is also reduced, resulting in reduction in construction cost and inclination of the joint outlet side. The possibility of water leakage accident can be reduced. Further, since the joint outlet side is rotatable around the axis, it becomes easy to adjust the position of the joint by bending the pipe, so that it is not necessary to strictly adjust the pipe length. It has a great effect on improving workability.

Next, since the diameter of the wall opening is slightly larger than the sum of the diameters on the outlet side of the pair of joints, the opening operation is almost the minimum necessary and the opening operation is easy because the opening is circular. The cost can be reduced, and the member that covers and covers the wall opening can be smaller than in the related art, so that the design can be improved and the cost can be reduced. Furthermore, since the joint outlet side connects the wall surface member and the wall back member with a connecting member that penetrates a portion other than the area occupied in the wall opening, it is not necessary to enlarge the wall opening for the connecting means. It does not make the work difficult or increase the size of the member that covers and covers the wall opening, so that the cost and design are not adversely affected. That is, a substantially minimum necessary wall opening can be effectively used.

In the structure for mounting a mixing faucet according to claim 2,
Positioning means is provided on the wall surface member and / or wall back member at a position which does not interfere with the joint outlet side and the connecting member and is substantially inscribed in the wall opening. Therefore, it is necessary to enlarge the wall opening for the positioning means. Because there is no, not only does the opening work become difficult or the members that cover and hide the wall openings are enlarged, so that costs and designs are not adversely affected.In addition, if positioning means is provided on both the wall surface member and the wall back member, Since both are naturally settled in substantially the predetermined positions, the connecting operation of both becomes easy. In addition, even when the positioning means is provided on one side, both of them are located at a substantially predetermined position by the connection, so in any case, the mixing faucet body attached and fixed to the wall surface member and / or the wall back member is also provided.
Naturally, it can be settled substantially at a predetermined position, and there is no need to take time for positioning, so that the construction cost can be reduced. In other words, the substantially necessary minimum wall opening can be used more effectively than the mixing faucet mounting structure of the first aspect.

In the structure for mounting a mixing faucet according to claim 3,
Since the positioning means is a projection protruding toward the wall opening side, a simple structure is sufficient, and it is easily possible to integrally form an effective shape by, for example, press molding for a metal member and, for example, by injection molding for a resin member. And the cost can be reduced.

In the mounting structure of the mixing faucet according to the fourth aspect,
When the positioning means is provided on both the wall surface member and the wall back member, both projections are arranged so as not to overlap in a front view. This eliminates the danger that it will not be possible to tighten and fix.
