Features. The cover faucet of claim 4 is claim 2 or
4. The cover faucet according to claim 3, wherein the installation is performed.
The surface is a wall panel made of resin .

In each of the present inventions, since the connecting portion is provided on the back side of the faucet main body, the pipe can be routed below the connecting portion, so that an area almost directly below the faucet main body can be made an empty area. The cover faucet may be a single faucet or a hot and cold water faucet. In the latter case, a water-side connection part connected to a water supply pipe (pipe) and a hot-water connection part connected to a hot water supply pipe (pipe) are provided on the back side of the faucet body.

In each of the present inventions, the connection portion is located in a region on the indoor side of the installation surface .

That is, the above-mentioned conventional product (Japanese Patent Laid-Open No. 1-2873)
No. 21) has a structure in which a connection portion provided on a faucet body is buried on the back side of an installation surface, and connection between this connection portion and a pipe is performed on the back side of the installation surface. Therefore, connection and detachment of the connection portion and the pipe must be performed through an inspection port or the like that opens at the front of the installation surface, and the workability during construction and maintenance is poor. In addition, when the piping is disposed behind the installation surface, replacement of the piping requires a great deal of time and cost when a problem such as water leakage occurs in the piping.

On the other hand, in each of the present inventions , the connecting portion provided on the back side of the faucet is located in the area on the indoor side of the installation surface, and the piping can be processed in front of the installation surface. Installation and maintenance of the cover faucet and pipe replacement work become easy.

[0010] Note that, as in the present the invention is not limited to the faucet body having a connecting portion to the rear, even faucet body provided on the side surface or the bottom surface or the like, place it in front of the predetermined plane In such a case, an empty space is generally provided between the faucet main body and the predetermined surface, instead of closely adhering the back surface to the predetermined surface. Then, according to the present invention, it is possible to effectively use this empty space.

That is, if a connecting portion is provided on the back side of the faucet main body and the connecting portion is disposed in a region on the indoor side of the installation surface, the connecting portion is provided in an empty space between the back surface and the installation surface. Can be paid. If the connecting portion is connected to the pipe in this space, and the pipe is routed downward along the installation surface, the space almost immediately below the faucet main body surely becomes an empty area.

[0012]

Embodiments of the present invention will be described below. In the present embodiment, an example in which the cover faucet according to claims 1 to 4 is applied to a unit bath will be described. This cover faucet is, as shown in FIGS.

Installation surface 70 to which this cover faucet is attached
As shown in FIG. 3, is configured using a wall panel of a unit bus (for example, made of resin such as FRP). The installation surface 70 is provided with a step-shaped concave portion 71 vertically long along the vertical direction. Both sides along the longitudinal direction of the concave portion 71 are formed as shallow bottom portions 72 with a small concave amount, and other portions are concaved. The deep bottom portion 73 has a large amount.

As shown in FIG. 3, the upper side of the concave portion 71 is a space for arranging the faucet main body 10 and the like, and the shallow bottom portion 72 is provided with a screw hole 75 used for fixing the cover 20. Further, near the inner wall surface of the deep bottom portion 73, a water supply pipe W connected to a water supply source, a water supply pipe H connected to a hot water supply source, and a shower pipe S connected to a shower head are set up.

As shown in FIG. 2, the faucet main body 10 has a built-in temperature control device 11 for controlling the mixing of hot and cold water and a switching device 12 for controlling the flow rate and switching the water discharge direction. . Further, as shown in FIG. 3, from the left end of the faucet main body 10, a mounting part 1 composed of a spindle for operating the temperature control device 11 and a protruding part for inserting and retracting the spindle.

Further, as shown in FIG. 3, from both sides on the back of the faucet main body 10, a water-side connection portion 1 connected to the water supply pipe W is provided.
5 and a hot water side connection portion 16 connected to the hot water supply pipe H protrude. In addition, as shown in FIG. 4, a water discharge pipe mounting portion 17 is provided near the front surface substantially at the center of the lower surface of the faucet body 10,
A shower pipe connecting portion 18 hangs down from the back near the center of the lower surface.

The faucet body 10 is attached to the inner wall surface of the deep bottom portion 73 using a stay 60 as shown in FIG. The stay 60 includes a vertically-long rectangular receiving plate portion 61, a pair of left and right rib-like portions 62 hanging from both edges along the longitudinal direction, and a mounting plate portion integrated with these rear end surfaces. 63. Of these, the receiving plate 61
Are provided with two insertion holes A and B along the longitudinal direction. Further, two screw passage holes are formed at both ends of the mounting plate 63 (not shown).

When attaching the stay 60 to the faucet main body 10, first, as shown in FIG. 5, the water discharge pipe mounting portion 17 is aligned with the insertion hole A on the front side of the receiving plate portion 61 and the rear side. The shower pipe connection part 18 is inserted into the insertion hole B. Next, the upper end of the water discharge pipe T is inserted into the insertion hole A, and the male screw part M of the water discharge pipe T is screwed into the female screw part m of the water discharge pipe attachment part 16.

Thus, the lower end face d of the water discharge pipe mounting portion 16
Then, the receiving plate portion 61 is sandwiched between the flange portion F of the water discharge pipe T and the stay 60 is sandwiched and fixed between the faucet main body 10 and the water discharge pipe T. Then, as shown in FIG. 3, when the mounting plate 63 is screwed and fixed to the inner wall surface of the deep bottom portion 73, the attachment of the faucet main body 10 to the installation surface 70 is completed.

In the present embodiment, the stay 60 and the installation surface 70 can be provided without any contrivance such as providing a fixing flange on the faucet body 10 (see a conventional product disclosed in Japanese Patent Application Laid-Open No. 1-287321). Can be attached to the faucet body 10. That is, it is not necessary to prepare a specially-designed faucet body 10; for example, a faucet body of another type of faucet, such as a wall-mounted type, can be diverted.
The manufacturing effort and cost of the cover faucet is reduced.

In this embodiment, two insertion holes A and B
Since the water discharge pipe T and the shower pipe connection part 18 are inserted into the stay 60 and the stay 60 is supported at two points,
The “rattle” on the water faucet body 10 of 0 is reliably prevented.

Further, in this embodiment, as shown in FIG.

These connection parts 15 and 16 are stored in the inside. And
Since each of the pipes W and H is routed from this empty space K to almost directly below, the space almost directly below the faucet main body 10 and the like is reliably an empty area.

In the present embodiment, since the connecting portions 15 and 16 and the pipes W and H are located in a region on the indoor side of the installation surface 70 (the deep bottom portion 73), the front surface of the concave portion 71, that is,
From the area on the indoor side, the connection portions 15 and 16 and the pipes W and H
Since the connection work can be performed, construction and maintenance are easy. Further, when a problem such as water leakage occurs in the pipes W and H, it is easy to perform the replacement work.

The cover 20 is made of a material (for example, made of a resin such as ABS of the same color as the wall panel) which is regarded as the same as the wall panel, and as shown in FIG. A portion 21 and a frame portion 22 surrounding the portion 21 are provided. The lateral width of the cover 20 is slightly larger than the lateral width of the concave portion 71, and a ridge 2a that can be fitted into the upper side of the concave portion 71 is provided on the peripheral edge of the rear surface in a frame shape.

Further, as shown in FIG. 1, a stepped U-shaped notch a having a large front half and a small rear half is provided on both side surfaces of the housing portion 21. Is provided with a rectangular notch b which is continuous with the notch a. A cutout 23 extending from each side surface of the housing 21 to the frame 22 is formed by the cutouts a and b. The notch 23 is open on the back side of the cover 20 and has a size that allows the above-described mounting portions 13 and 14 to be inserted.

Further, as shown in FIG.
A mounting recess 25 is provided which is continuous with the rear end of the notch 23, and a screw passage hole 26 is formed in the recess 25. Further, screw passage holes 2 are also provided on both sides on the lower end side of the frame portion 22.
7 are provided. The lower part of the front surface of the housing part 21 is slightly expanded and the lower surface is opened, and the water discharge pipe housing part 2 is opened.
8 is set.

The sub-cover 30 is also made of the same material as that of the cover 20 (for example, made of resin such as ABS), and has a shape in which the notch 23 of the cover 20 is substantially inverted with respect to the notch 23, as shown in FIG. . Specifically, the shape is substantially semi-elliptical,
A head 31 having a U-shaped leg on the back surface and a bent portion 32 having a bent plate shape are provided. The head 31 is provided with an insertion hole 33 through which the above-mentioned attachment portions 13 and 14 can be inserted along the axial direction.

In this embodiment, as shown in FIG.
First, the cover 20 is attached to the installation surface 70 on which the faucet main body 10 is attached. This attaching work is performed so as to cover the upper side of the concave portion 71 with the entire cover 20 while covering the faucet main body 10 with the housing portion 21 (see FIG. 1). At this time, each of the mounting portions 13, 14 of the faucet body 10
Is inserted into the notch 23 and does not hinder the attachment of the cover 20.

However, as shown in FIG.
Since the distance between the protruding ends of the three and 14 (the distance between the protruding ends of both spindles) is slightly larger than the distance between the left and right mounting recesses 25 of the cover 20, the notches 23 of the two mounting portions 13 and 14 are provided. Are not performed simultaneously, but are performed one by one while slightly moving the cover 20 left and right.

Further, at the time of this attaching work, the cover 20 is slightly moved up and down so that the water discharge pipe T is accommodated in the water discharge pipe housing part 28 while slightly exposing the lower end thereof (see FIG. 4 and the like). . Then, when the mounting screw N is screwed into the screw hole 75 through the screw passage holes 26 and 27, the attachment of the cover 20 is completed.

Following the cover 20, the sub-cover 30 is attached while the mounting portions 13 and 14 are inserted through the insertion holes 33 as shown in FIG. By the attachment of the sub cover 30, the notch 23 and the mounting recess 25 of the cover 20 are concealed. Although not shown, the sub cover 30 is not shown.
Is fixed to the cover 20 by an engaging portion provided on one side,
The sub-cover 3 is engaged with an engaged portion provided on the other side.
0 is fixed by screwing.

After the sub-cover 30 is attached, the corresponding handles 81 and 82 are attached to the mounting portions 13 and 14 which are respectively exposed to the left and right. In addition, the lower half side where the concave portion 71 is exposed can be concealed by a concealing panel or the like.

In this embodiment, the cover 20 is provided with an appropriate notch 23 so that the handles 81 and 82 can be positively arranged on the side of the bulging portion of the cover 20. That is, in the above-mentioned conventional product, an insertion hole is provided in the cover,
Through this insertion hole, a structure in which the projecting portion of the faucet main body 10 (a portion exposed outside the cover after the cover is attached, such as the mounting portions 13 and 14 of the present embodiment) is exposed to the outside of the cover. It has become. For this reason, it is difficult to attach / detach only the cover while the faucet main body 10 is attached to the installation surface 70. This is because the attachment / detachment direction of the cover is the front-back direction of the installation surface 70,
This is because the mounting portions 13 and 14 obstruct the attachment / detachment of the cover since the projection directions of the projections 3 and 14 are the left and right directions.

As described above, when the cover provided in the conventional product is used and the projection provided on the faucet main body does not coincide with the attaching / detaching direction of the cover, the attaching / detaching of the cover must be integral with the faucet main body. However, the workability of construction and maintenance of this type of cover faucet deteriorates.

On the other hand, in this embodiment, the cover 20 has the notch 23 which is open on the back side. When the cover 20 is attached or detached, the attachment portions (projections) 13 and 14 are inserted through the notches 23. Therefore, the faucet body 10
Can be smoothly attached and detached even when the cover 20 is still attached to the installation surface 70.
1, 82 can be positively placed at desired locations.

In this embodiment, since the cover 20 and the sub-cover 30 are not fixed to the faucet main body 10 with fixing members such as screws, when the cover 20 and the sub-cover 30 are attached and detached,
There is no need to tighten or remove such a fixing member at all. Also from this point, attachment and detachment of the cover 20 and the like are performed smoothly.

Further, in this embodiment, each handle 81, 82
Is provided on the side of the bulging portion of the cover 20 that is hardly noticeable, and the water discharge pipe T is substantially accommodated in the cover 20. Moreover, not only the notch 23 but also the mounting screw N mounted on the mounting recess 25 is concealed using the sub-cover 30. Further, the mounting screw N on the lower side of the cover 20 is also concealed by the concealing button G (see FIG. 1). Also, the dividing lines of the cover 20 and the sub-cover 30 correspond to the front left and right of the cover 20,
Because it only appears as a line of simple shape behind the side,
The entire cover faucet is in a state of being appropriately assimilated with the installation surface 70.

Further, in the present embodiment, the erroneous operation of the handles 81, 82 is prevented by disposing the faucet handles (same for levers) 81, 82 on the side of the bulging portion of the cover 20. Is being planned. That is, in the above-mentioned conventional product,
A state in which the faucet handle and the like are exposed in the direction of attaching and detaching the cover,
That is, since the cover is generally disposed so as to protrude from the front surface or the like, the user's body, clothes, or the like may erroneously come into contact with the cover and cause erroneous operation of the handle or the like.

On the other hand, in this embodiment, both handles 8
By providing 1 and 82 on the side of the bulging portion of the cover 20, it becomes difficult for the user's body, clothes, and the like to contact the handles 81 and 82. Also, each handle 81, 82 is
Are arranged separately on both sides of the steering wheel, even if the steering wheel operation is performed by groping, the steering wheel 81, 8 to be operated
It is unlikely that the two will be mistaken.

The present embodiment is a cover faucet having a temperature control handle 81 and a switching handle 82, but may be a cover faucet of another type such as a one handle type, a single lever type, or a two handle type. It is the same even if there is. In particular, if the present invention is applied to a two-handle type cover faucet and the handles on the water side and the hot water side are arranged on both sides of the cover, the person washing the hair may mistakenly operate both handles and get hot water. This has a great significance in that it can be reliably prevented.

In this embodiment, each handle 81, 8
2 is provided on the side of the bulging portion of the cover 20, and the water discharge pipe T is substantially accommodated in the cover 20.
That is, in the cover faucet of the type protruding forward of the installation surface 70 as in the present embodiment, the amount of forward projection is minimized. Therefore, the present embodiment is suitably used for a small unit bus.

Further, in this embodiment, since the sub cover 30 is provided with the insertion hole 33 through which the mounting portions 13 and 14 can be inserted, the dividing line between the cover 20 and the sub cover 30 crosses the mounting portions 13 and 14. There is no need to provide in the state. That is, in the present embodiment, the dividing line is a simple-shaped line that appears on the front left and right sides of the cover 20 and the rear side of the cover 20 to improve the appearance of the cover faucet.

The scope of each invention is not limited to the above-described embodiment, and various modifications can be made within the scope of each invention.

That is, in the present embodiment, the case where the installation surface 70 is constituted by a wall panel is exemplified.
0 may be a wall surface or a deck surface made of mortar, tile, or the like.

In the present embodiment, the cover 20 is provided with the notches 23 corresponding to the mounting portions 13 and 14, however,
When the faucet main body 10 has “another protruding portion” that hinders attachment / detachment of the cover 20, the faucet main body 10 corresponds to the “other protruding portion” together with the cutout 23 or instead of the cutout 23. Other notches may be provided.

The "other projecting portion" is, for example, a water discharge pipe (such as a water projecting pipe larger than the water discharge pipe T of the embodiment), a part attached to a faucet body such as a shower elbow, or the like. In addition, various attachment parts provided on the faucet body for attaching these parts in a projecting manner, and attachment fittings (for example, cap nuts and the like) used for attaching parts such as a water discharge pipe to the attachment parts ) Can be exemplified.

Further, when the shower elbow is detachably attached to the faucet body 10, the stay 60 is clamped and fixed together with the water discharge pipe T or by using a shower elbow instead of the water discharge pipe T. You may. Further, the stay 60 may be sandwiched and fixed between the faucet body 10 and a fitting (for example, a cap nut) for attaching the water discharge pipe T or the shower elbow to the faucet body 10.

The stay 60 can be positioned by using another protruding portion provided on the faucet main body 10, for example, a connection portion (15 or 16) with a pipe. In this case, for example, from the rear end side of the receiving plate portion 61 of the stay 60,
The back plate may be raised, and an insertion hole for inserting the connection portion into the back plate and a notch engaged with the connection portion may be provided.
