BACKGROUND OF THE INVENTION This invention relates to a structure for mounting a faucet on a counter.

[Problems to be Solved by Conventional Techniques and Inventions] As one type of faucet, there is a type that is installed by a wet method in an embedded manner. FIG. 10 shows an example thereof. In the figure, reference numeral 100 denotes a faucet body, which has a hot and cold water mixing section 101 and a fixed water blocking section 108. The hot and cold water mixing unit 101 is connected to a hot water supply pipe 102 and a water supply pipe 104, and hot water and water supplied from the hot and cold water supply pipe 102 and the hot water supply pipe 104 are used for the hot and cold water mixing unit 101.
In addition, the fixed water stop portion 108 is mixed through the passage 106.
Sent to. In the fixed quantity water stop unit 108, the water stoppage and the discharge water quantity are quantified, and a fixed amount of water is supplied to the passage 110 and the water outlet 1.
When it is discharged through 12, the water flow is automatically stopped. That is, the water discharge is stopped. A part of the passage 110 also serves as a water outlet holding portion.

In the case of this mixed faucet, as shown in FIG. 10, the faucet body 100 is embedded in the base 115, and the spout 112, the handles 116 and 118, and the metal base spray. A makeup plate 124, which includes a plate 120 and a display plate 122 for displaying the adjusted temperature and the like, is installed so as to be exposed on the mounting surface.

FIG. 11 shows a specific installation / construction method. As shown in the figure, in the case of this faucet, the base body 115 is provided with a notch 126, and the faucet body 1 is provided there.
00 is arranged to connect the hot water supply and water supply pipes 102 and 104 projected into the notch 126 to the hot water mixing section 101. After covering with protective covers (curing covers) 128 and 130, the notch 126 is filled with mortar and the notch 126 is formed.
Fill in. That is, backfilling with mortar is performed.

Here, the protective cover 128 is the hot and cold water mixing section 10.
1 and the fixed amount water blocking portion 108 are protected, and the protection cover 130 is the water outlet 112 in the water outlet holding portion 113.
It protects the joint part of. The spout holder 113
An outward annular protrusion 117 is provided on the outer peripheral surface of the protective cover 130, and the protective cover 130 is put on the water outlet holding portion 113 from above until it hits the protrusion 117.

Now, in this way, the protective covers 128, 13
After covering with 0, the notch 126 is filled by filling the notch 126 with mortar. Protective cover 12 after backfilling
After removing 8, 130, the spout 112 is connected to the spout holding portion 113 as shown in the figure, and the makeup plate is also attached.
The lock 124 is fixed and the handles 116 and 118 are assembled.

The fixing of the makeup plate 124 is performed as follows. In this water faucet, female screw holes 127 and 129 are integrally provided in the housing of the water faucet body 100, and as shown in FIG.
124 (specifically, a metal base plate 120)
The lower end of the screw 125, which is inserted from above, is screwed into these female screw hole portions 127, thereby fixing the decorative plate 124 on the mounting surface.

That is, in the case of this faucet, since there is no mating member for directly fixing the makeup plate 124 when installing the faucet, a female screw for fixing the makeup plate to the housing of the faucet body 100 in advance. A hole is provided, and the decorative plate 124 is fixed by utilizing this female screw hole.

By the way, when installing a faucet by such wet construction, the construction is troublesome, the number of steps is large, and the construction period is long. Therefore, particularly in a unit bath room or the like, if the faucet can be attached to the counter by dry construction, the faucet can be easily installed, which is desirable.

However, in the case of the above-mentioned faucet, since it is planned to be installed in a wet-type and embedded type, it does not have any special fixing means for a counter or the like, and therefore this is fixed to the counter as it is. It is not possible.

On the other hand, if a separate faucet for fixing the counter (for fixing the counter with the same type of faucet) is prepared, two types of products for wet construction and dry construction are required, which makes parts management troublesome. However, it is easy to make a mistake in the parts and bring in the wrong parts to the site, causing trouble.

[0012]

[Means for Solving the Problems] The present invention has been made to solve such problems, and its gist is to dispose mounting plates on both front and back sides of a counter,
By threading a screw member from above on the mounting plates and screwing the threaded portion at the tip to the housing of the faucet body disposed on the back side of the counter, the counters are attached to the upper and lower surfaces of the pair of mounting plates. The faucet body is fixed from the side so that the faucet body is fixed to the counter.

[Operation and Effect of the Invention] As described above, according to the present invention, the screw member is penetrated through the pair of mounting plates so that the tip end side is screwed to the screw connection portion of the water faucet body. .

As is apparent from the above description, this screw connection portion of the faucet body is originally provided for fixing the decorative plate in the embedded faucet. Can be used to fix the faucet body to the counter (however, it is also possible to use another screw connection part separately provided).

Therefore, it becomes possible to attach the conventional embedded water faucet as it is to the counter by the dry method without any modification. Therefore, it is not necessary to prepare two types of products so that both wet construction and dry construction can be performed.

In addition, if the same type of faucet can be attached to the counter not only by wet construction but also by dry construction, restrictions on the location of the faucet and the like are remarkably alleviated and the usability is greatly increased. For example, since the unit bath room is generally provided with a counter, such a faucet can be installed in the unit bath room by a dry method.

In the present invention, it is preferable that the screw connection portion of the faucet body is a female screw hole, and a male screw member such as a screw is screwed into the female screw hole to facilitate the work of fixing the faucet.

It is also convenient to provide the screw member with a second screw portion, for example, a female screw portion, into which a separate screw or the like can be screwed. In this case, the decorative plate can be fixed to the counter upper surface by screwing a screw or the like into the female screw portion, and the trouble of fixing the decorative plate to the counter upper surface by a separate means can be omitted.
