Description

The present invention relates to a wall-built faucet in which the faucet body is arranged on the back side of the wall to suppress protrusion on the indoor side, and it is possible to easily and accurately install the faucet body along the wall surface. It is about the configuration that was done.

The entire faucet connected to the water supply pipe to the toilet etc. is arranged on the indoor side, but in recent years, the faucet body is arranged on the back side of the wall and the spout connected to the water supply pipe. A wall-mounted water stopcock (also called a water outlet) has been proposed in which only the water outlet and the operation portion of the valve that opens and closes the water passage to the spout are exposed to the indoor side.

According to such a wall-built faucet, the protrusion on the indoor side can be made much smaller than that of a general faucet, so that a large effective space on the indoor side is secured and the appearance is neat.

By the way, in the installation work of the water stopcock built in the wall, it is necessary to connect the water distribution pipe on the back side to the water stopcock main body before constructing the wall. Therefore, the fixing destination of the water stop valve main body is not the wall itself, but a wall back construction material such as a stud that has been constructed in advance before the wall is constructed. Then, the water stopcock main body is fixed to such a wall back construction material, a wall is constructed after connecting the water distribution pipe, and an opening leading to the water stopcock main body is provided in this wall to provide a spout portion and a valve operation portion. Is exposed to the inside of the room, and an appropriate decorative cover is attached to complete the installation. After the installation, a water supply pipe is connected to the spout and the valve operation unit is operated in the open direction to supply water to the water supply destination device such as a toilet.

In such an installation work, if the water stopcock main body is directly fixed to the wall back construction material, the position cannot be adjusted at all after the wall is constructed. The height position in the vertical direction is not required to be very strict, but the purpose of using this kind of wall-built faucet is to reduce the protrusion on the indoor side in the front-back position in the thickness direction of the wall. , Strictness is required rather than height position. However, depending on the thickness of the wall to be built after that, the spout may protrude too much toward the room, or conversely, it may be deeper than necessary. It may be difficult to determine the front-back position of.

Therefore, the applicant is provided with a box for accommodating the water stopcock main body so as to be slidable horizontally in the front-rear direction along the thickness direction of the wall, and this box is fixed at an appropriate height position of the wall back construction material to stop water. Disclosed is a wall-built faucet in which the front-rear position of the faucet body can be adjusted via an opening after the wall is constructed by accommodating the faucet body (Patent Document 1). According to this, after the wall is constructed, the protrusion of the spout portion and the valve operation portion from the indoor side can be made appropriate. Finally, the water stopcock main body whose front-rear position has been determined is fixed to the box by screwing or the like, and a decorative cover is attached to the opening to complete all the installation.

Japanese Unexamined Patent Publication No. 2015-1067

In the wall-built water stopcock of Patent Document 1, the worker adjusts the front and back of the water stopcock main body while checking the protruding condition of the spout portion and the like by the scale. Therefore, there is a possibility that the front-rear position of the water stop valve main body may be uneven depending on the operator, and skill is required to obtain an appropriate front-rear position.

Further, the slide structure in Patent Document 1 is due to the engagement between the concave rail portions in the front-rear direction provided on the left and right of the water stop cock main body and the convex rail portions in the front-rear direction provided on the left and right inner surfaces of the box. Since there is a clearance (play) between the concave rail part and the convex rail part, it is permissible to install the spout part so that the direction of the spout part is slightly deflected to the left or right. Skill is still required for the adjustment work to be directed.

In short, in the wall-built faucet of Patent Document 1, the work of adjusting the front and rear of the faucet body depends on the skill of the operator without having an objective reference point in the installation work, so that construction unevenness may occur. There was a problem that the direction of the spout part and the like became inappropriate.

The present invention has been made to solve the above-mentioned problems, and an object thereof is a wall on which a water stopcock main body can be easily and accurately installed with the wall surface as a reference surface after the wall is constructed. The purpose is to provide a built-in water stopcock.

In order to achieve the above-mentioned object, in the present invention, a valve operation for opening and closing a spout portion for connecting a water supply pipe to a water supply destination device such as a toilet and an internal water passage to the spout portion on the front side facing the wall. A faucet main body having a portion and a connection portion with a water distribution pipe piped to the back side of the wall on the back side, and a water stop faucet main body arranged on the back side of the wall, the thickness of the wall. It has a mounting box that can be slid horizontally along the direction, and a base that is fixed from the indoor side to the front side of the faucet body via a work opening that penetrates the wall. The wall receiving portion of the positioning stay is provided with a positioning stay having a wall receiving portion that can come into contact with the indoor side wall surface around the opening of the wall integrally with the base portion, and the faucet body is slid. Was brought into contact with the indoor side wall surface of the wall, so that the amount of protrusion of the spout portion and the valve operating portion on the indoor side was defined with the indoor side wall surface as a reference surface.

In the procedure for installing the wall-built faucet of the present invention, before constructing the wall, first, the mounting box is fixed to the wall back construction material such as studs on the back side of the wall, and the faucet main body is housed in this mounting box. And connect the water pipe. Then, the main body of the water stopcock is slid to tentatively determine the rough front-back position and construct the wall. After that, a work opening is provided in the portion where the water stop cock main body is located on this wall, and the positioning stay is attached to the water stop plug main body from the indoor side through this opening. At this time, the wall receiving portion of the positioning stay is located on the indoor side. Can be made to protrude into the room by a predetermined amount. Further, the contact between the wall receiving portion and the indoor side wall surface stabilizes the orientation of the spout portion and the valve operating portion.

The number of wall receiving portions of the positioning stay may be one, but it is preferable that there are at least two pairs on the left and right or up and down. This is because the water stop valve main body can be installed without being deflected to the left or right or up and down by bringing the pair of wall receiving portions into contact with the indoor side wall surface at the same time.

Further, the wall receiving portion may have a shape that abuts on the indoor side wall surface, but is preferably a plate shape having a surface parallel to the indoor side wall surface as the abutting surface. This is because such a plate-shaped wall receiving portion makes surface contact with the indoor side wall surface in a wide range, so that deflection can be eliminated more reliably.

As described above, in the present invention, the front-rear position of the water stop valve main body can be made appropriate by the final adjustment work based on the positioning stay, but if the wall thickness is known in advance, the position thereof can be adjusted. By adjusting the front-rear position of the water stop valve main body to a position corresponding to the thickness before construction, the work of confirming the front-rear position by the positioning stay is sufficient at the final stage. As such a pre-adjustment means before wall construction, in the present invention, the mounting box has a back surface parallel to the wall, and the back surface portion abuts on the water stop cock main body to restrict the slide to the rear thereof. A possible slide restricting portion is provided horizontally, and the slide restricting portion has a claw folding portion that is arbitrarily cut according to the thickness of the wall on the tip side thereof, and slides to the rear of the water stop cock main body. It can be regulated in stages depending on the presence or absence of excision of the claw fold.

Further, the mounting box and the water stopcock main body are provided with a guide rail portion that engages with each other in an uneven manner to slide the water stopcock main body in the front-rear direction, and the guide rail portion provided in the mounting box has a wall at the tip thereof. The lengths of the upper and lower steps are different depending on the thickness of the water stopcock, and the front and back positions of the water stopcock body are set to the wall by aligning the water stopcock body with the tip surface of each of the upper and lower steps as a reference. A means of making it adjustable in stages according to the thickness of the is also used.

In this means, the mounting box is further provided with a viewing window for visually observing the tip portion of the guide rail portion from the outside, and the tip portion is visually observed through the viewing window to visually check the positional relationship between the tip portion and the water stop cock main body. As a reference, the front-rear position of the water stop valve main body can be adjusted.

In addition, the water stopcock main body is fixed to the guide rail part of the mounting box by a screw that inserts the guide rail part from diagonally above. According to this means, when fixing the water stop valve main body to the mounting box, the driver uses other members during construction in both the temporary fixing before the front and rear positions are fixed and the main fixing after the fixing. It can be installed from the indoor side without interfering with.

In the present invention, the front-rear position of the water stop valve main body can be easily and accurately determined by the positioning stay.

Further, when the thickness of the wall is known in advance, the front-rear position of the water stop valve main body can be determined with the accuracy according to the positioning stay by the pre-adjustment means even before the construction thereof.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an exploded perspective view of a wall-mounted faucet according to an embodiment of the present invention. In the figure, 1 is a water stop valve main body, 2 is a mounting box thereof, 3 is a positioning stay, and 4 is a decorative cover. Further, W is a wall, and B is a wall back construction material such as a stud that has existed on the back side of the wall W before its construction.

The water stopcock main body 1 is located between a water distribution pipe (not shown) connected to the back side of the wall W and a water supply pipe (not shown) to a water supply destination device such as a toilet or a washing machine on the indoor side. As shown in detail in FIGS. 2 to 5, on the front side facing the wall W, a spout portion 1a connected to the water supply pipe and an internal water passage to the spout portion 1a are installed. A screw-type valve operating portion 1c that opens and closes 1b is provided in two upper and lower stages. Further, the connection portion 1d with the water distribution pipe is positioned at 90 degrees with the spout portion 1a toward the bottom.

In such a water stop valve main body 1, a screw hole 1e is provided on the front side between the water discharge port portion 1a and the valve operation portion 1c. The screw hole 1e is for screwing the positioning stay 3. Further, concave guide rail portions 1f having concave grooves formed on the left and right sides thereof are provided in the horizontal direction. A screw hole 1g that penetrates diagonally from above toward the inside of the groove is provided in the upper part of the guide rail portion 1f, and the water stop cock main body 1 is screwed to the mounting box 2 by using this screw hole 1g. I am doing it.

The mounting box 2 is arranged on the back side of the wall W, and in this embodiment, it is fixed to the side surface of the wall back construction material B. The front surface is opened to accommodate the water stop valve main body 1, and the water distribution pipe connecting portion 1d of the water stop valve main body 1 projects from the lower surface opening. The upper surface portion 2a, the left and right side surface portions 2b, and the back surface portion 2c are closed. Of these, elongated screw holes 2d are provided at the center of the upper surface portion 2a and at the upper and lower two locations of the left and right side surface portions 2b so that the mounting box 2 can be screwed to the wall back construction material B by any of the surface portions. ing.

Further, at the center of the inner surface of each of the left and right side surface portions 2b of the mounting box 2, a convex guide rail 2e that is inserted and engaged with the guide rail portion 1f of the water stop valve main body 1 is provided in the horizontal direction.

Further, each of the left and right side surface portions 2b is provided with a long hole-shaped viewing window 2f in which the tip end portion (front end portion) of the guide rail portion 2e can be visually recognized from the outside of the box.

The positioning stay 3 has a base portion 3a screwed to the screw hole 1e of the water stop cock main body 1 in the center, and is bent outward from the arm portion 3b that rises in the horizontal direction on each of the left and right sides thereof, and is inside the wall W. A plate-shaped wall receiving portion 3c that can come into contact with the wall surface W1 by surface contact is integrally provided. The wall receiving portion 3c is provided with a notch 3d in which the claws (not shown) provided on the decorative cover 4 are fitted and killed.

The decorative cover 4 has a size that conceals the wall receiving portion 3c of the positioning stay 4, and has these insertion holes 4a and 4b corresponding to the spout portion 1a and the valve operating portion 1c of the water stop valve main body 1. It is provided above and below. Further, a claw portion 4c that fits into the notch 3d of the positioning stay 3 is provided on the back surface.

Next, the procedure for installing the wall-embedded water stopcock having the above configuration will be described with reference to FIGS. 6 to 8. Place it in a row and insert a screw into the screw hole 2d from the inside of the box to fix it (FIG. 6 (a)). In the illustrated example, the left side surface of the mounting box 2 is fixed to the right side surface of the wall back construction material B, and the water stop valve main body 1 is fixed to the concave guide rail portion 1f of the concave guide rail portion 1f. The water stop valve main body 1 is housed in the mounting box 2 by inserting the portion 2e (FIG. 6 (b)). When the water stop valve main body 1 is housed in the mounting box 2, the water distribution pipe is connected to the downward connecting portion 1d.

At this stage, slide the water stopcock main body 1 to roughly determine the front-back position, insert the screw 1h into the screw hole 1g, lightly tighten this screw 1h, and temporarily attach the water stopcock main body 1 to the mounting box 2. Fix it. Since the screw hole 1g is inclined diagonally from the front to the back on the upper side of the guide rail part 1e of the water stop valve main body 1, it can be installed from the indoor side, and the driver for turning the screw 1h is also another member. Does not interfere. The pre-adjustment of the front-rear position of the water stop valve main body 1 at the time of temporary fixing will be described later.

After temporarily fixing the water stop valve main body 1, a wall W is constructed on the front side thereof. A through hole WH1 through which the spout portion 1a of the water stop cock main body 1 and the valve operation portion 1c are inserted is formed in advance on this wall W (FIG. 7A), but the water stop plug main body 1 is later attached to the mounting box. In order to secure an insertion port for the tool at the time of main fixing to 2, the through hole WH1 is enlarged by using the template T to form a rectangular opening WH2 (FIG. 7 (b)). In FIG. 7B, the right side of the opening WH2 is opened so that the positional relationship and structure of the water stop valve main body 1 and the like on the back side of the wall W can be confirmed. For convenience of explanation, the actual opening WH2 is closed around as shown in FIG.

Then, the positioning stay 3 is screwed and fixed to the water stop cock main body 1 from the indoor side via the opening W. At this time, the pair of left and right wall receiving portions 3c of the positioning stay 3 are located on the indoor side, and are in a state where they can come into contact with the indoor side wall surface W1 on the left and right of the opening WH2.

In this state, once the screw 1h is loosened to make the water stop valve main body 1 slidable, the left and right wall receiving portions 3c of the positioning stay 3 are simultaneously pressed against the indoor side wall surface W1 by fingers (FIG. 8A). ). By this work, the water stop valve main body 1 slides exactly horizontally in the mounting box 2 toward the back of the wall, the front-rear position of the water stop valve main body 1 is finally adjusted, and the spout portion 1a and the valve operation portion 1c. Is not deflected to the left or right, and the amount of protrusion from the indoor side wall surface W1 is also an appropriate amount.

After the final adjustment is completed in this way, while pressing the left and right wall receiving portions 3c against the indoor side wall surface W1, tighten the screws 1h to fix the water stop cock main body 1 to the mounting box 2 and make up. The cover 4 is attached to the positioning stay 3 in a state of being fitted and killed as described above (FIG. 8 (b)), and all the installation work is completed.

By the way, in the wall-built faucet of the present invention, the front-rear position of the faucet main body 1 can be accurately defined by the positioning stay 3 with the indoor side wall surface W1 of the wall W as a reference surface. If the front-rear position of the water stop valve main body 1 can be determined even before the construction of the wall W, the confirmation work by the positioning stay 3 or a slight fine adjustment is sufficient at the final stage. Further, if the water stop valve main body 1 is temporarily fixed in a state of being positioned at the back side of the mounting box 2 more than necessary before the wall W is constructed, the base portion 3a may be changed depending on the length of the arm portion 3b of the positioning stay 3. It does not reach the water stop valve main body 1, and it becomes difficult to fix the water stop valve main body 1 to the positioning stay 3.

Therefore, the pre-adjustment means for the front-rear position of the water stop valve main body 1 at the time of temporary fixing before constructing the wall W will be described with reference to FIGS. 9 to 11. First, as the first pre-adjustment means, the back surface of the mounting box 2 The portion 2c is provided with a rib-shaped slide restricting portion 2g that projects toward the front side. The slide restricting portion 2g abuts on the back surface 1i of the water stop valve main body 1 to restrict the slide of the water stop valve main body 1 to the rear. Further, the slide restricting portion 2g is provided with a claw folding portion 2h that can be excised by a finger or the like at the tip, and the rear slide of the water stop cock main body 1 is restricted in two stages depending on whether or not the claw folding portion 2h is excised. (Figs. 9 and 10).

Here, there are some standards such as the thickness of the wall W is 9.5 mm, 12.5 mm, and 15.0 mm. Since the difference between the thinnest thickness (9.5 mm) and the intermediate thickness (12.5 mm) is 3.0 mm, the wall with the thinnest thickness can be set by setting the protruding length of the claw folding portion 2h to 3.0 mm. And can accommodate walls of intermediate thickness. That is, if the thickness of the wall W is known to be an intermediate thickness (12.5 mm) in advance, the claw fold portion 2h is left uncut and is left until it comes into contact with the claw fold portion 2h when the water stop valve main body 1 is accommodated. Slide (Fig. 9). On the other hand, if it is known in advance that the wall W has the thinnest thickness (9.5 mm), the claw folding portion 2h is cut off and the water stop valve main body 1 is slid until it comes into contact with the slide restricting portion 2g. (Fig. 10).

In this way, the front-rear position of the water stop valve main body 1 can be adjusted in advance according to the thickness of the wall W by the slide restricting portion 2g and the claw folding portion 2h, but the thickest thickness (15.0 mm). In the case of), it is necessary to separate the water stop valve main body 1 from the back surface portion 2c of the mounting box 2 so that it does not come into contact with the claw folding portion 2h. That is, in this case, the claw folding portion 2h does not function.

Therefore, as a second pre-adjustment means, the tip portion of the convex guide rail portion 2e of the mounting box 2 is formed in a stepped difference in length at the top and bottom so as to correspond to such a thickest wall. The front and rear positions of the water stop valve main body 1 can be pre-adjusted in two stages with the two tip portions 2e1 and 2e2 as references (FIGS. 9 and 11). In this embodiment, the step between the two tip portions 2e1 and 2e2 is set to the difference (2.5 mm) between the thickest thickness (15.0 mm) and the intermediate thickness (12.5 mm), and the wall W is the thickest. If it is known to be thick, align the base side base of the arm portion 3b of the positioning stay 3 with the longer tip portion 2e1 (FIG. 11), and if it is known to be an intermediate thickness, the shorter tip portion. Align the base with 2e2 (FIG. 9). This alignment work can be easily performed visually through the viewing window 2f provided on the side surface portion 2b of the mounting box 2.

In this way, when the thickness of the wall W is known, the front-rear position of the water stop valve main body 1 can be adjusted in advance according to the thickness of the wall before its construction, and the accuracy thereof is the positioning stay 3. At the final stage, confirmation work by the positioning stay 3 or slight fine adjustment is sufficient.

The present invention is not limited to the above embodiment, and for example, the wall receiving portions 3c of the positioning stay 3 are preferably at least a pair on the left and right, but may be one, and the shape thereof is also plate-shaped. It is preferably present, but it may be rod-shaped. What is required in the present invention is that the wall receiving portion 3c comes into contact with the indoor side wall surface W1 so as to define the front-rear position of the water stop plug main body 1 with the indoor side wall surface W1 as a reference surface.

Further, the pre-adjustment means of the water stop valve main body 1 before the construction of the wall W is also effective when the thickness of the wall W is known, but it is also possible to omit the adoption when the thickness of the wall W is not known.

Further, regarding the installation direction of the water stop valve main body 1, generally, as shown in FIG. 1, the connection portion 1d with the water distribution pipe is installed so as to face directly downward, but depending on the piping mode of the water distribution pipe, FIG. 12 By fixing the mounting box 2 upside down as shown in FIG. 13, it is also possible to turn the connecting portion 1d upward as shown in FIG. Further, if the mounting surface of the mounting box 2 with respect to the wall back construction material B is the upper surface portion 2a, the connection portion 1d of the water stop valve main body 1 can be installed sideways. Depending on such an installation orientation, the wall receiving portion 3c of the positioning stay 3 can correspond to either the left or right or the top and bottom of the opening WH2 of the wall W.
