BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply pipe terminal provided on the rear surface side of a substantially plate-shaped mounting portion and a water faucet arranged on the front surface side of the mounting portion. A water supply configured by connecting a water supply tap to the front side of the attachment part while connecting through a connector having a rear connection part connected to the terminal of the above and a front connection part connected to the connection port of the water supply tap. Regarding the mounting structure of the stopper.

[0002]

2. Description of the Related Art Conventionally, when attaching a water faucet to a mounting portion that constitutes a wall surface, a counter surface, a deck surface, etc.
Between the terminal of the water pipe and the water tap, a connecting tool for connecting the water pipe to the surface side of the mounting portion, and connected and fixed to this connecting tool, projecting to the surface side of the mounting portion, that is, the room It has been practiced to intervene with a socket or the like. However, in recent years, without using a socket or the like for the purpose of suppressing the amount of protrusion of the faucet into the room,
It is practiced to connect the faucet directly to the fitting.

For example, in the conventional example 1 of FIG. 7A, the connector S inserted into the through hole 11 of the mounting portion 10 from the surface 15 side.
The aspect which connects the water tap 20 is shown. In this connecting tool S, the intermediate portion 38 and the rear connecting portion 33 are inserted into the through hole 11 from the surface 15 side of the mounting portion 10, and the flange portion 31 extending toward the root side of the front connecting portion 32 is provided on the surface 15. Abut. Then, the fixing nut 91 is screwed into the male screw 39 on the peripheral surface of the intermediate portion 38, and the fitting portion 10 is sandwiched between the fixing nut 91 and the flange portion 31 to fix the connector S. Further, the water pipe 90 is connected to the rear connecting portion 33 via the cap nut 93 and the like, and the connection port 25 of the water tap 20 is connected to the front connecting portion 32.

[0004]

However, in the prior art example 1, the fixing nut 91, the cap nut 93 and the like can be attached and detached on the back surface 12 side of the mounting portion 10 at the time of construction and maintenance of the connecting tool S. Will be needed. Therefore, it is necessary to open a work opening 95 of a sufficient size in the mounting portion 10, and this may lead to a deterioration in the appearance of the mounting portion 10.
In addition, as shown in FIG. 7A, the work of attaching and detaching the fixing nut 91 is likely to be a blind spot for a worker who looks into the working opening 95 from a place very close to the rear surface 12 of the mounting portion 10, that is, the room. The workability is poor because it is performed at a place where it is difficult to insert a tool or the like. Further, since the tightening operation of the fixing nut 91 has to be performed by groping, the tightening amount is likely to vary, the tightening amount is insufficient, and the connector S rattles, or the tightening amount is small. There is a case where an excessive amount is applied and an excessive tightening force is applied to the mounting portion 10. In particular, when the mounting portion 10 is made of a material having low rigidity such as resin such as a wall panel of the unit bath, this excessive tightening force causes the mounting portion 1
0 may cause problems such as unnecessary distortion and cracks.
Therefore, according to Conventional Example 1, the connector S and the water pipe 9
0, and eventually, it may be difficult to smoothly perform the construction and maintenance of the water tap 20.

Further, in Conventional Example 1, as shown in FIGS. 7 (a) and 7 (b), the flange portion 31 is brought into contact with the surface 15 of the mounting portion 10 and used as the attachment reference of the connector S. ,
The amount of protrusion C from the back surface 12 of the connector S varies depending on the thickness of the mounting portion 10. Then, as shown in FIG. 7B, when the mounting portion 10 becomes thick, the back surface 12 of the mounting portion 10
At a location closer to the rear connecting portion 33 and the water pipe 90
It is necessary to perform connection work with. Therefore, also in this connection work, it is necessary to perform an inefficient work as in the attachment / detachment work of the fixing nut 91.

Further, in the prior art example 1, when the wall panel or the like forming the mounting portion 10 is replaced or the water pipe 90 is maintained due to water leakage or the like, first, the mounting portion 10 is firstly attached.
It is necessary to perform the work of attaching / detaching the water pipe 90 and the connecting tool S, the work of attaching / detaching the fixing nut 91, and the like on the back surface 12 side, which requires a great deal of time and effort.

On the other hand, JP-A-9-3993 and FIG.
Conventional example 2 shown in (a) shows a mode in which the water tap 20 is connected to the connector S inserted from the rear surface 12 side of the through hole 11 of the mounting portion 10. In this connecting tool S, the rear connecting portion 3
3 is connected to a water pipe through a cap nut or the like, the front connecting portion 32 is inserted into the through hole 11 from the rear surface 12 side of the mounting portion 10, and the flange portion 3 extended to the root side of the front connecting portion 32.
1 is brought into contact with the back surface 12. Then, the fixing nut 91 is screwed onto the male screw 39 on the outer peripheral surface of the front connecting portion 32, and the fitting portion 10 is sandwiched between the fixing nut 91 and the flange portion 31 to fix the connector S. Further, when the male screw 40 on the outer peripheral surface of the connection port 25 is completely screwed into the female screw 41 on the inner peripheral surface of the front connecting portion 32, the attachment of the water faucet 20 is completed.

In the second conventional example, the front connecting portion 32 is used.
The water tap 20 is attached with reference to. However,
In this connecting tool S, the flange portion 31 is attached to the rear surface 12 of the attaching portion 10.
8 (a) and 8 (b), the protrusion amount D of the front connecting portion 32 toward the front surface 15 side of the mounting portion 10 changes according to the plate thickness of the mounting portion 10. . Therefore, depending on the thickness of the mounting portion 10, the forward amount E of the water faucet 20 also changes. For example, if the mounting portion 10 is thick, the forward amount D and the forward amount E decrease. Here, the surface 15 of the mounting portion 10
When the back surface of the water tap 20 is brought into contact with the
An unnecessary compression force is applied between the back surface of the water tap 20 and the surface 15 of the mounting portion 10. In particular, when the water faucet 20 is provided with the cover 22, the cover 2 is affected by this compressive force.
Since there is a possibility of causing problems such as unnecessary deformation and cracks in No. 2, there is a problem in applying this Conventional Example 2 to the water tap 20 having a cover. On the contrary, when the mounting portion 10 is thin and the amount of protrusion D and the amount of protrusion E are excessive, the back surface of the water tap 20 cannot be brought into contact with the front surface 15 of the mounting portion 10, and the back surface of the water tap 20 is unable to contact. And a surface 15 of the mounting portion 10 creates a useless gap. As described above, in Conventional Example 2, it may be difficult to properly attach the water tap 20 depending on the plate thickness of the attachment portion 10.

Incidentally, in Japanese Patent Laid-Open No. 9-3993, FIG.
As shown in (c), there is also proposed a mode in which a nut 97 for an adjuster is added to the back surface 12 side of the mounting portion 10 so that the amount of protrusion D of the front connecting portion 32 can be adjusted. But,
In this mode, not only the number of parts is increased, the time and effort for construction and maintenance of the connecting tool S and the like are increased, but also complicated work is inevitable for the accurate adjustment of the adjuster nut 97. Moreover, since the adjuster nut 97 is attached to the rear surface 12 side of the mounting portion 10, the adjuster nut 97 is used for fine adjustment and the like.
When operating the lock nut 91 of the above-mentioned conventional example 1
Similar to the above, inefficient blind work is required. As described above, according to the conventional example 1 and the conventional example 2, various problems occur due to the thickness of the mounting portion 10. Therefore, at the construction site, the connecting tool S having various total lengths is prepared, and the plate of the mounting portion 10 is prepared. It is necessary to use them properly according to the thickness.

The present invention has been made in view of such circumstances, and an object of the present invention is to facilitate construction and maintenance of a water faucet, a connecting tool, and the like, and moreover, depending on the thickness of the mounting portion. It is an object of the present invention to provide a mounting structure of a water faucet which can obtain a suitable mounting state of the water faucet.

Is constant. In addition, in the present invention, when fixing the connector to the mounting portion, the fixing member is attached from the front surface side of the mounting portion, so that the work on the back surface side of the mounting portion is not required.
Furthermore, since the amount of protrusion of the connecting tool from the back surface of the mounting portion is always the same, it is possible to always connect the rear connecting portion and the water pipe under a constant condition regardless of the thickness of the mounting portion.
Further, in the case of exchanging the attachment portion, the attachment portion can be removed from the connector by removing the fixing member from the surface side of the attachment portion.

Here, the "water faucet" of the present invention may either expose the water faucet body or cover the water faucet body with a cover. Also, in the "mounting part",

The specific embodiment of the “fixing member” of the present invention is not particularly limited, and includes, for example, (1) a flange surface or a seat surface that comes into contact with the peripheral portion of the through hole on the surface of the mounting portion, and is connected from the surface side of the mounting portion. "Fixing nut" that is screwed and fastened to the tool, and clamps the fitting part to the fitting part by sandwiching the fitting part between the flange surface or the seating surface and the fitting, and (2) Attaching to the fitting with a set screw As a result, it is possible to exemplify “a retaining member” or the like for retaining the connecting tool from the through hole of the mounting portion.

The "mounting reference surface" of the present invention is not limited to (A) the surface of the mounting portion, but is (B) the "surface of inclusions" interposed between the surface of the mounting portion and the water tap. Then, it may be installed such that the projection amount or the recess amount is always constant from the surface of the mounting portion. Examples of the “surface of inclusions” in (B) include the surface of a mounting stay that is attached to the mounting portion and supports the water faucet, or the surface of a fixing member. The "contact portion" can be provided, for example, on the rear surface of the water faucet body or the rear end surface of the cover that covers the water faucet body. In the present invention, the method of connecting the connection port and the front connecting portion is not particularly limited, and will be described later.
In addition to the "insertion connection" of the invention, "screw engagement" and the like can be exemplified.
In the case of using this "screw engagement", the amount of screw engagement between the male screw provided at one of the connection port or the front connecting portion and the female screw provided at the other is the "mounting reference surface" and the "abutment surface". It is possible to control the amount until the "part" abuts.

Next, in the mounting structure of the water faucet of the invention of claim 2, "in the mounting structure of the water faucet of the invention of claim 1,
The point is that the front connecting portion and the connecting port are inserted and connected to each other. "

That is, if the front connection portion and the connection port are connected by screwing, the screwing amount of both may be slightly excessive, but according to the insertion connection of the present invention, one is simply inserted into the other. Therefore, the insertion amount of both can be finely adjusted to ensure an appropriate amount.

Further, in the mounting structure of the water faucet of the invention of claim 3, "in the mounting structure of the water faucet of the invention of claim 2,
"The front connecting part is formed in a female type, and the connection port is formed in a male type."

If the front connecting portion is formed in a male shape, a seal portion is provided on the outer surface of the front connecting portion with the inner surface of the connection port. In this case, when inserting the front connection part into the through hole, the seal part may come into contact with the inner wall surface of the through hole and be damaged, resulting in a defective seal. It is necessary to do it. On the other hand, in the present invention, since the seal portion is provided on the inner surface of the front connecting portion that is inserted into the through hole, there is no risk of damaging the seal portion when the front connecting portion is inserted into the through hole.

Further, in the water faucet mounting structure according to the fourth aspect of the present invention, "In the water faucet mounting structure according to any one of the first to third aspects of the invention, a mounting stay for supporting the water faucet is provided.
It is fixed to the surface of the mounting portion by using the fixing member ”. According to the invention of claim 4, since it is not necessary to use a separate member for fixing the mounting stay to the mounting portion, it is possible to reduce the number of parts and the number of working steps, thereby reducing the labor and cost for construction, maintenance, etc. of the water faucet. Can be reduced.

Finally, in the water faucet mounting structure according to the fifth aspect of the invention, "in the water faucet mounting structure according to any one of the first to fourth aspects, the water faucet is provided with a cover."
Is the gist. According to the present invention, the faucet body, the fixing member, and the like can be hidden by the cover, so that the appearance of the entire faucet is improved.

Further, the water faucet 20 may be another type such as a single faucet, a water purifier faucet, or an alkaline ionized water producing device.

The faucet main body 21 has a temperature control valve for controlling the mixing of hot water and a flow path switching valve for switching the discharge flow path and the flow rate. The temperature control valve is configured using, for example, (1) a temperature sensitive element such as a wax element or a shape memory alloy element that deforms in response to temperature changes, and automatically adjusts the degree of mixing of hot water and water. Thermostat system, (2) Sliding disc system composed of a fixed disc and a movable disc that slide relative to each other to open and close the flow path, and (3) Adjust the degree of mixing of hot water and water with separate handles. Various types such as a two-handle type can be used. Also, as the flow path switching valve,
Various methods such as (4) a sliding disk method and (5) a lift method for advancing and retracting the valve element with respect to a pair of opposed valve openings to switch the flow path and adjust the flow rate can be used.

As shown in FIG. 3, a hot water-side connection port 25 for supplying hot water to the temperature control valve projects from the left side of the back side of the faucet body 21, and the temperature control valve from the right side of the figure. A water-side connection port 25 for supplying water is projected. The hot water / water side connection ports 25 show one specific example of the “connection port” of the present invention, and the number of the single water faucet is one. Further, a smooth surface 26 is provided in a raised shape on the peripheral portions on the root side of both the connection ports 25, and the smooth surface 26 constitutes one specific example of the "contact portion 26" of the present invention. The contact portion 26 of each invention is a smooth surface 26 of this embodiment.
However, it may be concave or convex. Further, the location where the contact portion 26 is formed is not limited to this example, and may be the rear end surface of the cover, for example.

As shown in FIGS. 1 and 5, the water faucet body 2
The connection portion 27 of the water discharge pipe 44 hangs down from the front of the bottom surface of 1.
As shown in FIG. 1, a connecting portion 28 of the shower hose hangs from the rear of the bottom surface. Further, as shown in FIG. 3, an operating portion 2A for operating the temperature control valve is attached to the left side surface of the water faucet body 21, and the flow path switching valve is attached to the right side surface of the water faucet body 21. The operation unit 2B for operating is attached.

As shown in FIG. 1, the mounting portion 10 is provided upright in front of the back wall 1A of the bathroom. Further, as shown in FIGS. 2 and 3, both the hot water side and the water side connection ports 2 described above are provided.
Two through-holes 11 and 11 are formed at substantially the same pitch as 5 and 25. Further, between the inner wall 1A and the mounting portion 10, a terminal of a hot water supply water supply pipe 90 and a terminal of a water supply water supply pipe 90 both of which are rigid pipes are routed. Each water pipe 90 may be configured by using a flexible pipe. In the present example, the water tap 20 described above is connected to the mounting portion 10 by the connector S having a pair of left and right adapters 30, 30 and a fixed stay 50, a fixing member 60, a mounting stay 70, and a lower stay 80. It is attached using and.
The details will be described below.

As shown in FIG. 2, the adapter 30 is a tubular member in which a flange portion 31 is integrally extended from a peripheral surface of an intermediate portion, and the front portion of the flange portion 31 is a front connecting portion 32, and the rear portion of the flange portion 31 is a rear portion. The rear connecting portion 33 is used. Further, the front connecting portion 32 has an outer diameter capable of being inserted into the through hole 11 described above, and a male screw 34 is engraved on the outer peripheral surface. Further, two circumferential grooves are provided on the inner circumferential surface of the front connecting portion 32, and seal members 35, 35 are fitted in the respective circumferential grooves.
A male screw 36 is engraved on the outer peripheral surface of the rear connecting portion 33, and a pair of left and right chamfered portions 37 is provided on the outer peripheral surface.

As shown in FIG. 2, the fixed stay 50 fixes both adapters 30 at a desired pitch. The fixed stay 50 is configured by using a thin plate having a substantially rectangular shape, and has substantially oval fixing holes 51 formed at both ends thereof.
The pitch between the two fixing holes 51 is equal to that of the two through holes 1.
The pitch is substantially the same as 1 and 11. In this example, the rear connecting portion 33 of the adapter 30 is inserted into the fixed stay 50 from the front side thereof. At this time, since the chamfered portion 37 of the rear connecting portion 33 comes into contact with the linear inner edge portion of the fixing hole 51,
The adapter 30 is fixed to the fixed stay 50 so as not to rotate. Then, the nut 52 is screwed into the male screw 36 of the rear connecting portion 33 from the rear surface side of the fixed stay 50, the both adapters 30 are fixed to the fixed stay 50, and the connecting tool S as a whole.
Make up.

Further, as shown in FIG. 3, a cap nut 93 is used for the left rear connecting portion 33 to supply hot water to the water pipe 90.
The terminal of the water supply pipe 90 for water supply is similarly connected to the right rear connecting portion 33. As a result, the connecting tool S is configured by using a rigid pipe while holding the front connecting portion 32 in a state of being arranged at substantially the same pitch as both the hot water side and water side connecting ports 25, 25 described above. Both water pipes 90 are supported in a cantilever shape. However, in each of the present inventions, the use of the fixed stay 50 may be omitted, or instead of the fixed stay 50, a fixing tool of another aspect such as a box shape may be used.

In this example, the connection work between each water pipe 90 and each rear connection portion 33 is performed before the mounting portion 10 is erected in front of the inner wall 1A. Then, as shown in FIG. 2, each front connecting portion 32 is inserted into the through hole 11 from the rear surface 12 side of the mounting portion 10 with the sheet packing 16 interposed therebetween, as a part of the standing operation of the mounting portion 10. As a result, each front connecting portion 32 is placed in each through hole 11. Further, in this example, according to the invention of claim 3, since each front connecting portion 32 is formed in a female type and the seal members 35, 35 are not exposed to the outside, the inside of each through hole 11 is not exposed during this insertion work. The wall surface and “burrs” existing on the inner wall surface do not come into contact with the seal members 35.

By this insertion work, the flange portion 31 of each adapter 30 of the connector S contacts the peripheral portion of the through hole 11 on the back surface 12 side with the sheet packing 16 interposed therebetween. In this example, the flange portion 31 of the adapter 30 is in contact with the back surface of the mounting portion 10.
The flange portion 31 of the fixing stay 50 is omitted, and the fixed stay 50 is attached to the mounting portion 1.
It may be in contact with the back surface of 0. In this example, since the connector S contacts the back surface 12 side of the mounting portion 10, the rearward amount C of the connector S is as shown in FIGS. 4 (a) and 4 (b).
It is constant regardless of the plate thickness of the mounting portion 10. In contrast,
In the above-mentioned conventional example 1, since the post-projection amount C of the connecting tool S varies depending on the plate thickness of the mounting part 10, when the connecting tool S and the water pipe 90 are connected after the connecting tool S is mounted on the mounting part 10. Is forced to use a flexible pipe capable of absorbing the above “variation” as the water pipe 90. In this regard, in each of the present inventions, as described above, even if the connecting tool S and the water pipe 90 are connected after the connecting tool S is attached to the mounting portion 10, the squeezing amount C of the connecting tool S is as described above. Since it is constant regardless of the plate thickness of the mounting portion 10, it is not necessary to absorb the variation in the post-delivery amount C, and it is possible to use not only a flexible pipe but also a rigid pipe as the water pipe 90. .
In each of the present invention, the connection work between each water pipe 90 and each rear connection portion 33 and the insertion work of the front connection portion 32 into the through hole 11 are performed by the mounting portion 10 that is provided upright in front of the inner wall 1A.
When it is performed on the back surface 12 side, the mounting portion 10 may be provided with an appropriate working port, and from the viewpoint of workability, it is preferable to use the water pipe 90 formed of a flexible pipe.

That is, the insertion amount of the front connecting portion 32 into the through hole 11 is regulated by the flange portion 31, and the insertion amount of the fixing member 60 into the through hole 11 is regulated by the fixing collar 61.
By adjusting the screwing amount, the thickness of the mounting portion 10 is offset. Therefore, regardless of the thickness of the mounting portion 10, the surface 63 of the fixed collar 61, that is, the mounting reference surface 63 always projects from the surface 15 of the mounting portion 10 by the same amount, and It will always be constant.

Further, in this example, at the rear end of the fixing member 60,
An extension portion 65 extending inward is provided, and the extension portion 65 ensures a sufficient area of the attachment reference surface 63.

In the present invention, the manner of attaching the fixing member 60 and the front connecting portion 32 is not limited to that shown in this embodiment. For example, as shown in FIG.
From 0, the extension portion 65 may be omitted. In this case,
The amount of screwing the male screw 34 into the female screw 62 can be changed over a wide range, and can be applied even when the mounting portion 10 is extremely thin.
