DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows an overall configuration around a faucet faucet according to the present invention. As shown in FIG. 1, this configuration is such that a faucet attached near the bowl of the wash basin has a crane neck 10 that is a water pouring spout, a pedestal 20 that supports the crane neck 10 and has a water passage that communicates with the crane neck, and And a water supply pipe 30 connected to the base 20 for supplying water.
[0008]
The crane neck 10 is fixed to the pedestal 20 by a one-touch operation by a latch mechanism provided at the lower part of the crane neck 10 and the upper end of the pedestal 20 (not shown), and the work itself is performed at the final stage.
[0009]
The connection between the base 20 and the water supply pipe 30 is performed before the base 20 is fixed to the washstand. Therefore, the portion closest to the pedestal 20 of the water supply pipe 30 is a flexible pipe so that it can be pulled out to the top of the wash basin together with the pedestal 20, and after the installation work of the pedestal 20 is completed, it is removed from the wall surface using a one-touch connector (not shown). Connect to a protruding water pipe (not shown).
[0010]
FIG. 2 is an exploded view showing the crane neck 10 and the pedestal 20 in FIG. 1 in more detail. The crane neck 10 includes a water inlet 11a, a base portion 11b, a water channel connecting portion 11c, and an operation button 12, and has a latch structure for fixing to a pedestal 20 at a lower portion (not shown).
[0011]
The pedestal 20 has a faucet pedestal 22 inserted from above into a fixed pedestal 21 inserted into the mounting hole of the wash basin from above, and the threaded portion of the faucet pedestal 22 is screwed into the nut portion 26. The faucet pedestal 22 is provided with a water passage 24 into which the water passage connecting portion 11c of the crane neck 10 is inserted at the center thereof, and a flat portion on which the base 11b of the crane neck 10 is placed around the entrance of the water passage 24 Is formed.
[0012]
The upper end of the pedestal 20 is configured as a pedestal for attaching the crane neck 10 at the same time as a pedestal for fixing the pedestal 20 itself to the washstand. That is, a disk-shaped raised faucet pedestal 22 is provided at the center of the circular flange-shaped pedestal 21, and a pair of latch grooves 23 are provided on the peripheral surface of the faucet pedestal 22. One-touch fixing of the crane neck 10 and the pedestal 20 is performed.
[0013]
FIG. 3 is an exploded view of the mounting relationship between the fixed base 21 and the faucet base 22.
The faucet pedestal 22 has two stages of screw portions 25 having different diameters formed below the disk-shaped upper portion. The large diameter screw portion 25a is for engaging the screw cut on the inner peripheral surface of the nut portion 26 of the fixed base 21 to fix the faucet base 22 to the fixed base 21, and the small diameter screw portion 25b is This is for connecting the water supply pipe 30.
[0014]
On the other hand, the fixed base 21 is connected to the nut portion 26 by wires 27, and both ends of the wire 27 are bent and exposed at the upper surface of the fixed base 21 at the upper end, and the nut portion is not shown at the lower end. It is in the state exposed to the lower surface of 26. Thus, the fixed base 21 and the nut portion 26 are coupled by the wire 27 so as to be movable within a predetermined range in the vertical direction and the rotational direction. (Here, the wire 27 may be integrally cast with the fixed base 21 to improve the strength.)
Therefore, when the faucet pedestal 22 is screwed into the fixed base 21, the nut portion 26 rotates very slightly, and thereafter the faucet pedestal 22 is screwed. At this time, as will be described later, the swinging claw 28 gradually changes its angle from the outer peripheral surface of the nut portion 26 and protrudes.
[0015]
FIGS. 4A to 4C show how the swinging claw 28 provided on the nut portion 26 moves in and out. FIG. 4A shows a side shape of the nut portion 26. The nut portion 26 has a substantially short cylindrical shape, and is a vertically long recess for providing, for example, four swinging claws 28 on the outer peripheral surface thereof. Is provided. And, two grooves are provided in the circumferential direction so as to cross the recess, and a band 29 made of stainless steel is fitted in each groove. 28 is supported.
[0016]
4 (b) and 4 (c) show a longitudinal section in which the nut portion 26 is cut at a position where the swinging claw 28 is provided. The swinging claw 28 has a substantially L-shaped side surface, and band grooves are formed in the upper and lower portions inside the vertical portion. The swinging claw 28 swings around the upper band groove, and is formed by the lower band groove. The swing range is restricted. 4 (b) shows a state in which the swinging claw 28 is pushed out from the inside and protrudes most, and FIG. 4 (c) shows a posture in a natural state without applying any acting force to the swinging claw 28. ing.
[0017]
That is, in the state where the faucet pedestal 22 is screwed into the nut portion 26, the back surface of the swinging claw 28 is pushed by the thread of the large diameter screw portion 25a of the faucet pedestal 22 and swings, gradually changing the angle, As a result, it protrudes from the outer peripheral surface of the nut portion 26 to the state shown in FIG. Accordingly, the washstand is sandwiched between the lower surface of the fixed base 21 and the protruding portion of the swinging claw 28. By fixing the faucet base 22 firmly, the fixed base 21 can be fixed to the washstand.
[0018]
And when passing the fixed base 21 into the mounting hole of the washstand, since the faucet base 22 is not yet screwed, the swinging claw 28 is in a state of entering inward as shown in FIG. The fixed base 21 can be easily inserted into the mounting hole of the washstand.
[0019]
5 to 7 show an assembling process of the faucet faucet according to the present invention. First, Fig.5 (a) is a step which inserts the fixed base 21 in a washstand. Next, as shown in FIG. 5B, the faucet base 22 is inserted into the fixed base 21. At this time, the water supply pipe 30 is already attached to the small-diameter screw portion of the faucet pedestal 22, and the water supply pipe is inserted into a hole provided in the center of the fixed base 21 from the tip where the one-touch connector of the water supply pipe is attached.
[0020]
6A, the faucet pedestal 22 inserted in the fixed base 21 is rotated clockwise to screw the large-diameter screw portion of the faucet pedestal 22 into the nut portion 26, and the swinging claw 28 is protruded. Shows the stages. As shown in FIG. 6B, when the faucet pedestal 22 is fully screwed, the swinging claw 28 protrudes to the maximum extent, and between the flange of the fixed base 21 and the swinging claw 28. The wall material of the washstand is sandwiched. FIG. 7 (a) shows a stage where additional tightening is occurring by putting a dedicated tool on the latch groove while the faucet base 22 is screwed. As a result, the faucet base 22 is firmly fixed to the fixed base 21. Next, as shown in FIG. 7B, the crane neck 10 is attached to the faucet base 22. This can be done with one touch by inserting the water channel connecting portion 11c of the crane neck 10 into the water channel 24 of the tap pedestal 22 and rotating the crane neck 10 counterclockwise.
[0021]
Thereafter, the water supply pipe 30 is connected to a water pipe (not shown) by a one-touch connector, and the crane neck 10 is attached to the faucet base 22 to complete the connection work.
[0022]
【The invention's effect】
In the present invention, as described above, the pedestal is constituted by the fixed pedestal having the swinging claw and the faucet pedestal fixed by screwing to the fixed pedestal. Therefore, the fixed pedestal is installed and the faucet pedestal is screwed and fixed to the fixed pedestal. At this time, since the swinging claw protrudes outward and cooperates with the fixed base to fix the base to an attachment target such as a washstand, the base can be attached at the upper part of the washstand. For this reason, it is very easy to attach and remove the faucet, and the workability can be greatly improved.
