The inner peripheral surface of the adapter body 30 is provided with a semicircular boss portion 50 (two locations in this example) protruding inward (see FIG. 8). As shown in FIGS. 6 and 8, the boss portion 50 is formed with an insertion hole 52 that penetrates the boss portion 50 in the up-down direction.
4, 36 are inserted downward from the upper side.

On the inner peripheral surface of the adapter main body 30, semicircular protrusions 54 are formed at four locations spaced at predetermined intervals in the circumferential direction (see FIG. 8). A guide projection 5 formed by projecting the projections 54 downward from the lower surface of the flange portion 38 is provided at the lower portion of the adapter body 30.
6 are formed. The guide projections 56 allow the adapter main body 30 to move the counter 1 in the faucet mounting hole 24.
When the adapter main body 2 is mounted, the faucet mounting hole 24 is fitted with a predetermined clearance to guide the adapter body 30 in positioning.

With these guide projections 56, the adapter body 30 can be easily set at an appropriate position.
That is, the lower surface of the adapter body 30 is
It can be seated on the surrounding counter 12 upper surface,
The adapter main body 30 can be prevented from being set at a position deviated from the faucet mounting hole 24. Thereby, a large contact area between the adapter body 30 and the upper surface of the counter 12,
That is, a seal area can be secured.

As shown in FIGS. 2 and 4, the holder 32 is a member that sandwiches the counter 12 from the back side thereof, and has a plurality of engaging teeth 58 on its upper surface over the entire length in the circumferential direction. The engaging teeth 58 are strongly pressed against the back surface of the counter 12.
The holder 32 has a curved shape as a whole, more specifically, a substantially arc shape, and its circumferential length is equal to or longer than half the circumference of the faucet mounting hole 24.

The holder 32 is provided with protrusions 60 and 62 that protrude inward at positions near both ends in the circumferential direction. As shown in FIG. 6, the projecting portions 60 and 62 are formed with female screw holes 64 penetrating vertically, and the pair of male screw members 34 and 36 are respectively formed in the female screw holes 64. It is to be screwed.

It should be noted that one of the protrusions 62 is connected to the other of the protrusions 60.
And a substantially semicircular elastic clip (contact portion) 66 as a positioning means.
Is provided. The center of the elastic clip 66 is formed in a direction and a position exactly corresponding to the center of the female screw hole 64.

One male screw member 34 of the pair of male screw members 34, 36 is longer than the other male screw member 36 by a certain length, and the male screw member 36 reaches the female screw hole 64 in the holder 32. In a state where one of the male screw members is not provided, one male screw member 34 is screwed into the corresponding female screw hole 64, and the tip of the male screw member 34 projects downward from the holder 32. A nut 68 (FIGS. 6 and 11) is screwed into the distal end of the male screw member 34 projecting downward from the holder 32.

The nut 68 is for preventing the holder 32 from dropping off, and at the same time as a lock nut (resistor) for rotating the holder 32 together with the male screw member 34 before being mounted on the counter 12. Also serves as a work.

Next, a procedure for mounting the adapter device 28 of this embodiment to the counter 12 will be described with reference to FIGS. First, as shown in FIG.
The longer male screw member 34 is inserted into the zero insertion hole 52, and this is screwed into one of the female screw holes 64 of the holder 32 until its lower end projects downward from the holder 32. Then, a nut 68 is screwed into the lower end protruding downward, and the nut 68 is fully tightened. At this time, the nut 68 functions as a lock nut, and the holder 32 rotates integrally with the male screw member 34, that is, the holder 32 rotates.

Now, as shown in FIG. 9 (I), the holder 32 is rotated clockwise around the male screw member 34, that is, the free end of the holder 32 is in the radial direction with respect to the adapter body 30. 9 (II), the entire adapter device 28 is tilted, and in this state, the holder 32 is inserted into the faucet mounting hole 24 from the free end side. By doing so, the holder 32 can be easily inserted into the faucet mounting hole 24 and positioned on the back side of the counter 12.

Subsequently, as shown in FIG. 10 (III), the male screw member 34 is rotated to integrally rotate the holder 32 on the back side of the counter 12. In other words, they rotate together. When the holder 32 is rotated to an appropriate position, the elastic clip 66 is moved in advance by the adapter body 30.
Is elastically fitted to the shorter male screw member 36 inserted through the other insertion hole 52 and comes into contact with the shorter male screw member 36. Here, the female screw hole 64 formed in the projecting portion 62 is in a state of correctly facing the shorter male screw member 36 correctly.

Then, as shown in FIG. 11 (IV), the male screw member 36 is screwed into the female screw hole 64 in the facing state, and the pair of male screw members 34 and 36 are further screwed in, so that the holder 32 is moved to the state shown in FIG. It is pulled upward from the position IV) and brought into contact with the back surface of the counter 12, specifically, the back surface along the periphery of the faucet mounting hole 24 (FIG. 7).

Further, by continuing the screwing operation of the male screw members 34 and 36, the adapter main body 30 and the holder 32 strongly sandwich the counter 12 from both sides, and the adapter device 28 is now mounted on the counter 12.

At this time, the guide projection 56 of the adapter main body 30 is fitted to the inner peripheral surface of the faucet mounting hole 24 with a predetermined clearance, and the lower surface of the flange portion 38 of the adapter main body 30 holds the ring-shaped packing 40. The seat 12 is seated on the upper surface of the counter 12 with a predetermined pressing force in a watertight manner. FIG. 7 shows the state at this time. FIG. 7
As shown in (1), the nut 68 is released from the function as a lock nut by screwing the male screw member 34, and thereafter acts only as a fall prevention member for the holder 32.

When the adapter device 28 is mounted on the counter 12 in this manner, the cylindrical portion 48 at the lower end of the faucet main body 14 is then fitted to the adapter main body 3 as shown in FIG.
0, and a stop screw 70 is inserted through the opening 74 of the cover ring 72 and the opening 76 of the cylindrical portion 48 rotatably attached to the faucet main body 14 so that the female screw hole 7
Screw into 8. Here, the faucet main body 14 and the adapter main body 30 are connected and fixed to each other so as not to rotate.

Then, the cover ring 72 is rotated to cover the opening 76 of the cylindrical portion 48 and the stop screw 70 in the faucet main body 14, and the decorative cap 80 is fitted into the opening 74 of the cover ring 72. Opening 7
4 is closed (see FIG. 2).

In the case of the water faucet mounting structure of the present embodiment, the two male screw members 34 and 36 are screwed to the single holder 32 and these are screwed to the adapter body 30. Even if a force in the rotational direction is applied to the faucet 10 in the state of attachment 10, the holder 32 is not displaced relative to the adapter body 30 in the rotational direction, and a strong fixing strength is obtained in the rotational direction. Therefore, it is possible to solve the problem that the faucet 10 is swung in the same direction on the counter 12 and the holder 32 comes off to the faucet mounting hole 24 side.

Since the holder 32 has a substantially arc shape extending along the periphery of the faucet mounting hole 24 and has a large circumferential length, the holder 32 can be extended over a wide range, that is, in the circumferential direction. It can be brought into contact with the back surface of the counter 12 over a long distance, so that the holding force of the counter 12 by the holder 32 and the adapter body 30 can be sufficiently increased. Therefore, according to this mounting structure, only one holder 32 can be provided for the adapter device 28, and the number of components can be reduced.

Further, since the holder 32 is long in the circumferential direction, the adapter body 30 and the holder 32 are separated from each other by male screw members 34, 3 at a position largely separated in the circumferential direction.
6, the deformation resistance of the adapter body 30 and the holder 32 in the rotational direction, and thus the strength in the rotational direction, can be effectively increased.

Further, since the holder 32 has an arc shape corresponding to the faucet mounting hole 24, the faucet mounting hole 24
The holder 32 does not become an obstacle when the supply pipe 26 or the like is passed through, so that a wide space can be secured inside the faucet mounting hole 24.

In this embodiment, since the elastic clip 66 is provided as positioning means for positioning the holder 32 in a state where the male screw member 36 and the female screw hole 64 are opposed to each other, the male screw member is rotated by operating the holder 32. This can be easily performed when the screw 36 is screwed into the female screw hole 64. In addition, at that time, the elastic clip 66 is elastically fitted into the male screw member 36 to prevent the position from being shifted.
When the holder 32 is rotated and positioned at a predetermined position, and the male screw member 36 is screwed into the female screw hole 64 in that state, the once positioned holder 32 does not shift, and the positioning state is reliably maintained. The male screw member 36 can be screwed into the female screw hole 64 while being operated.

In addition, in the case of the mounting structure of this embodiment, FIG.
When the holder 32 is inserted into the faucet mounting hole 24 and is rotated in the state shown in (1), the holder 32 is integrally rotated only by rotating the male screw member 34 by the action of the lock nut by the nut 68. Thus, the holder 32 can be easily brought to the proper angular position on the back side of the counter 12. As a means for rotating the holder 32 together with the male screw member 34, a method of applying a coating material or grease to the male screw member 34 or the female screw hole 64 to increase the frictional force therebetween can be used.

Further, in this embodiment, the flange portion 3 is provided over the entire length in the circumferential direction on the seating surface side of the adapter body 30 on the counter 12.
8, the adapter body 30 and the counter 1
A wide contact area, that is, a seal area, between the upper surface and the second upper surface can be secured.

Next, FIG. 12 shows another embodiment of the present invention. In this embodiment, an arc-shaped stopper portion 90 is raised on the side of the holder 32 at the periphery of the female screw hole 64, and the stopper portion 90 is formed. Are brought into contact with the male screw member 36, thereby positioning the holder 32 in the rotational direction. Also in this case, similarly to the above, the male screw member 36 is formed of a magnetic material, and the stopper portion 90 is formed of a magnet or a magnet is attached, so that the magnetic adhesion between the male screw member 36 and the magnet can be used.
The rattling between the male screw member 36 and the stopper portion 90 can be eliminated.

FIG. 13 shows still another embodiment of the present invention. In this embodiment, a long plate-like stopper portion 82 is hung down from the adapter body 30, and this stopper portion 82 is
In this example, the holder 32 is positioned so that the male screw member 36 and the female screw hole 64 of the holder 32 are correctly opposed to each other by making contact with the inner surface of the holder 32.

Incidentally, the mounting of the adapter device 28 to the counter 12 in this example can also be performed according to the procedure shown in FIG. That is, as shown in (I), the holder 96 is contracted in advance, and in this state, the holder 96 is inserted through the faucet mounting hole 24 as shown in (II), and after the insertion, the male screw members 34, 36 are pushed open. The adapter device 28 can be mounted by extending the holder 96 and then tightening the male screw members 34 and 36.

FIG. 19 shows still another embodiment of the present invention. In this example, the holder 104 is made of resin, and has a curved shape as a whole, more specifically, a substantially arc shape. In this embodiment, the circumferential length of the holder 104 is longer than half the circumference of the faucet mounting hole 24.

A notch 106 is formed in the holder 104 at an intermediate position in the circumferential direction, and a thin portion 108 is formed by forming the notch 106. The thin portion 108 can be elastically deformed in the closing direction in which both ends in the circumferential direction are brought close to each other, and can return to its original shape by its own restoring force when the elastic deformation force is removed. In this example, the holder 104 is elastically deformed in the closing direction, so that the holder 104 can be inserted into the faucet mounting hole 24 without being inclined as in the first embodiment.

When the holder 104 is elastically deformed,
The two ends can be elastically deformed by grasping both ends by hand to bring the ends closer to each other, that is, in the closing direction, or by applying an inward force to the shaft intermediate portions of the pair of male screw members 34 and 36. It can be elastically deformed in the closing direction,
Alternatively, the holder 104 can be elastically deformed by applying an inward force to the pair of male screw members 34 and 36 at a portion exposed upward from the insertion hole 94. Alternatively, the annular and inclined guide surface 1 on the lower surface of the holder 104
02 can be elastically deformed based on the guiding action.

On the other hand, when the elastic deformation force applied after inserting the faucet mounting hole is removed, the holder 104 is automatically replaced.
Spreads out and overlaps the back surface of the counter 12.
In this example, the holder 104 can be inserted into the faucet mounting hole 24 after being elastically deformed in the closing direction.
