Reference numeral 4 denotes a tubular faucet mounting foot, which is integrally provided at the lower portion of the mixing tap main body 1. And after inserting this faucet attachment leg 4 into the through-hole 6 opened in the faucet attachment plate part (henceforth only a face plate) 5 of a kitchen sink, for example, the said mixing plug main body 1 is fixed. A threaded portion 4 a is formed on the outer peripheral surface of the faucet mounting foot 4. Reference numerals 7 and 7 denote hot water and water supply pipes, which are connected to the bottom surface of the mixing plug main body 1, respectively. The face plate 5 is made of wood, for example, and at least the upper surface is covered with a thin stainless steel plate.
[0008]
8 is a clip made of an elastic material, and a ring-shaped nut member 10 having a screw portion 8a screwed to the screw portion 4a of the faucet mounting foot 4 on the inner peripheral surface, and an upper end outer peripheral surface m of the nut member 10 And a plurality of upper-opening blades 9 extending obliquely upward outward. The nut member 10 has an annular outer flange 11 extending in the radial direction on the outer peripheral surface m at the upper end, and the outer diameter P (see FIG. 3A) including the outer flange 11 is slightly smaller than the inner diameter of the through hole 6. The nut member 10 is configured so as to be inserted into the through hole 6. In this case, the lower flange 13a of the leg 13 is inserted into the outer flange 11 by inserting the leg 13 of the adapter 12 from above when the clip 8 and the adapter 12 described later are temporarily fixed to the faucet mounting foot 4. A plurality of cutouts 14 as leg fitting portions are formed with a predetermined interval. And by this notch 14, the outer flange 11 is comprised of a plurality of T-shaped flange portions 15 in front view, and the blades 9 are located on the upper end surfaces of the respective flange portions 15.
[0009]
On the other hand, the adapter 12 is composed of a rotating member 20 having a hexagonal outer peripheral surface n and a plurality of the legs 13 fitted into the notches 14 of the clip 8. Furthermore, the adapter 12 has a central hole 16 that is smaller than the through hole 6 and slightly larger in diameter than the faucet mounting foot 4. The adapter 12 is inserted into the faucet mounting foot 4 prior to the clip 8, and then is located below the face plate 5 through the through hole 6 from the temporarily fixed state in which the clip 8 is inserted into the faucet mounting foot 4. It functions to shift to the tightening state by rotating the clip 8. The rotating member 20 has a size that cannot be inserted into the through hole 6. Furthermore, in this embodiment, an annular groove 21 is formed on the outer peripheral surface n of the rotating member 20.
[0010]
In this embodiment, when the faucet body 1 is mounted on the face plate 5, a covering member 22 that covers the rotating member 20 is provided in order to avoid the rotating member 20 being seen. A screw hole 22a is formed in the covering member 22, and when the covering member 22 indicated by a solid line is placed on the upper surface 5a of the face plate 5, as shown by a two-dot chain line in FIG. The screw tip 23a is positioned in the annular groove 21 of the rotating member 20 by being screwed into the hole 22a.
[0011]
24 and 25 are seal packings, respectively.
[0012]
Thus, as shown in FIG. 3A, the covering member 22, the seal packing 24, the adapter 12, the seal packing 25, and the clip 8 are inserted into the faucet mounting foot 4 in this order.
[0013]
Subsequently, as shown in FIG. 3B, the covering member 22, the seal packing 24, the adapter 12, the seal packing 25, and the clip 8 are temporarily fixed to the faucet mounting foot 4. In this case, the operator screws the nut member 10 of the clip 8 onto the screw portion 4 a at the tip end position of the faucet mounting foot 4 and rotates the adapter 12 positioned above the clip 8 to rotate the adapter 12. The lower end 13 a of the leg 13 is fitted into the notch 14 of the clip 8. Thereby, it will be in the state temporarily fixed.
[0014]
Subsequently, as shown in FIG. 3C, in the temporarily fixed state, the supply pipes 7 and 7, the leg 13 of the adapter 12 in the temporarily fixed state, the clip 8, and the faucet mounting foot 4 are passed through the through hole. 6, and the clip 8 is positioned on the lower surface 5 b side of the face plate 5. At the time of this insertion, the blades 9 of the clip 8 are displaced from the outward obliquely upward direction to the axial direction side of the faucet mounting foot 4 so that the clip 8 can be easily inserted through the through hole 6. That is, since the clip 8 is made of an elastic material, the force in the direction indicated by A on the blade 9 is applied to the blade 9 even when the plurality of blades 9 are in the open state before being inserted into the through hole 6. By working, the blades 9 are deformed and pass through the through holes 6 in a form that slides on the walls of the through holes 6. And after passing, the blade | wing 9 returns to the open state similar to before insertion. In this case, the tip 9 a of the blade 9 contacts the lower surface 5 b of the face plate 5.
[0015]
Then, as shown in FIG. 3 (D), the temporary fixing state is shifted to the tightening state by the tightening operation by the tightening tool K of the rotating member 20 of the adapter 12. In this case, when the rotating member 20 is rotated in the tightening direction F, the clip 8 is also lifted from the lower end portion of the faucet mounting foot 4 while rotating the clip 8 in the same direction F via the legs 13 of the adapter 12. That is, the rotating member 20 and the clip 8 rotate together via the leg 13 fitted in the notch 14. By this rise, the blades 9 are further opened outwardly, the contact area with the lower surface 5b of the face plate 5 is increased, and the blade 9 is prevented from coming off. As a result, the mixing plug body 1 can be firmly attached to the face plate 5 in such a manner that the clip 8 and the adapter 12 press the face plate 5 from the lower surface 5b side and the upper surface 5a side of the face plate 5, respectively.
[0016]
In this manner, the mixing plug main body 1 can be mounted on the face plate 5 from above the face plate 5 in a state in which members such as the clip 8 and the adapter 12 are temporarily fixed. Further, the covering member 22, the seal packing 24, the adapter 12, the seal packing 25, and the clip 8 can be simply temporarily fixed by simply inserting them through the faucet mounting foot 4, and the clip 8 is positioned on the lower surface 5b side of the face plate 5. In this state, the mixing plug main body 1 can be firmly attached to the face plate 5 by a simple operation of simply tightening the rotating member 20 from above the face plate 5.
[0017]
FIG. 4 shows a second embodiment of the present invention in which the mixing stopper main body 1 can be mounted on the face plate 5 without covering the main body of the adapter. In FIG. 4, the same reference numerals as those shown in FIGS. 1 to 3 are the same or equivalent.
[0018]
Differences between the second embodiment and the first embodiment are as follows. That is, since the covering member 22 which covers the rotating member 20 is provided in the first embodiment, the annular groove 21 is formed on the outer peripheral surface n of the rotating member 20, and the screw hole 22a is formed in the covering member 22. Further, while the annular groove 21 is formed in the rotating member 20, in the second embodiment, the annular groove 21 as in the first embodiment is not formed in the rotating member 20.
[0019]
FIG. 5 shows that the annular outer flange 11 extending in the radial direction on the outer peripheral surface m of the nut member 10 has a predetermined interval instead of the notch 14 as the leg fitting portion used in the first and second embodiments. The third embodiment of the present invention is configured such that a plurality of small-diameter round holes 40 are provided, and the elongated legs 41 of the adapter 12 are inserted into the round holes 40 from above so that the lower ends 41a of the legs 41 are fitted. The form is shown. In FIG. 5, the same reference numerals as those shown in FIGS. 1 to 4 are the same or equivalent.
[0020]
In this embodiment, the screw portion is provided on the outer periphery of the leg 41, but the screw portion may not be provided on the outer periphery of the leg 41.
[0021]
6 and 7, the adapter 12 is provided with a cylindrical body 30 instead of the leg 41 used in the first to third embodiments, and the upper end of the ring-shaped clip 8 is provided on the circumferential surface P of the cylindrical body 30. A blade insertion hole 31 into which a plurality of upper opening-shaped blades 9 extending obliquely outward from the outer peripheral surface Q is formed is formed, whereby the rotating member 20 of the adapter 12 is opposite to the tightening direction F. When the faucet body 1 and the faucet mounting foot 4 rotated in the release direction R are replaced, the clip 8 can be easily taken out together with the adapter 12 above the face plate 5 without dropping into the lower sink part below the face plate 5. 4 shows a fourth embodiment of the present invention. In this embodiment, the covering member 22 of the first embodiment shown in FIG. 1 is not used. Moreover, in FIG. 6, FIG. 7, the same thing as the code | symbol shown in FIGS. 1-5 is the same or an equivalent.
[0022]
In this case, the cylindrical body 30 is provided at a position where it can be inserted through the through hole 6 on the lower surface H of the rotating member 20 of the adapter 12 so as to extend downward. A blade insertion hole 31 into which each blade 9 is inserted is formed on the peripheral surface P of the cylindrical body 30. On the other hand, the outer peripheral surface M of the clip 8 does not have an equivalent to the outer flange 11 as shown in the first to third embodiments. That is, the clip 8 according to the fourth embodiment has a very simple structure, and can be easily formed because it does not have a complicated structure like the outer flange 11, and the yield is also good.
[0023]
Thus, after inserting the seal packing 24, the adapter 12, the seal packing 25, and the clip 8 into the faucet mounting foot 4 in this order, as shown in FIG. The seal packing 24, the adapter 12, the seal packing 25, and the clip 8 are temporarily fixed. In this case, each blade 9 of the clip 8 is inserted into a blade insertion hole 31 of the cylindrical body 30 provided in the adapter 12.
[0024]
Subsequently, as shown in FIG. 7B, in the temporarily fixed state, the supply pipes 7 and 7, the cylindrical body 30 of the adapter 12 in the temporarily fixed state, the clip 8, and the faucet mounting foot 4 are penetrated from above the face plate 5. The clip 8 is positioned on the lower surface 5 b side of the face plate 5 through the hole 6. At the time of this insertion, the blades 9 of the clip 8 are displaced from the outward obliquely upward direction to the axial direction side of the faucet mounting foot 4 so that the clip 8 can be easily inserted through the through hole 6.
[0025]
Then, as shown in FIG. 7C, the temporary fastening state is changed to the fastening state by the fastening operation by the fastening tool K of the rotating member 20 of the adapter 12. In this case, when the rotating member 20 is rotated in the tightening direction F, the blade insertion hole 31 is also rotated, so that the clip 8 is also the same through each blade 9 inserted in the blade insertion hole 31. Ascending from the lower end of the faucet mounting foot 4 while rotating in the direction F. That is, the rotation member 20 and the clip 8 rotate together through the blade 9 fitted in the blade insertion hole 31. By this rise, the blades 9 are further opened outwardly, the contact area with the lower surface 5b of the face plate 5 is increased, and the blade 9 is prevented from coming off. As a result, the mixing plug body 1 can be firmly attached to the face plate 5 in such a manner that the clip 8 and the adapter 12 press the face plate 5 from the lower surface 5b side and the upper surface 5a side of the face plate 5, respectively. In this case, the lower end portion 33 of the clip 8 is positioned above the lower end portion 30 a of the cylindrical body 30 of the adapter 12.
[0026]
By the way, when the faucet body 1 and the faucet attachment foot 4 are replaced, when the turning member 20 is turned in the releasing direction R opposite to the fastening direction F, as shown in FIG. 8 descends along the threaded portion 4 a of the faucet mounting foot 4. As this descends, the blades 9 are displaced from the outward obliquely upward direction toward the axial direction of the faucet mounting foot 4, and each blade 9 comes out of the blade insertion hole 31. For this reason, after the blade 9 comes out of the blade insertion hole 31, the clip 8 does not rotate even if the adapter 12 rotates in the release direction R, and the outer surface of the blade 9 is directly below the blade insertion hole 31. The clip 8 is in a state of being screwed to the screw portion 4a of the faucet mounting foot 4 while being in contact with the inner surface of (see FIG. 6). In this case, the lower end portion 33 of the clip 8 is located below the lower end portion 30 a of the cylindrical body 30 of the adapter 12. Therefore, when the faucet body 1 and the faucet mounting foot 4 are exchanged, the face plate together with the adapter 12 can be obtained without dropping the clip 8 into the sink lower part below the face plate 5 by simply turning the turning member 20 in the releasing direction R. 5 Can be easily taken out upward.
[0027]
The faucet body 1 and the faucet mounting foot 4 may be formed separately.
[0028]
【The invention's effect】
As described above, according to the present invention, an operator can attach a faucet alone. In addition, the installation work time can be greatly shortened. Furthermore, since the work is performed from the face plate, the faucet can be securely attached and can be easily attached without specifying the operator. In addition, when replacing the plug body and the faucet mounting foot, the clip can be easily taken out together with the adapter above the face plate without dropping the clip into the sink lower part below the face plate by simply turning the turning member in the releasing direction. . It also has the advantage of using only two attachment members, a clip and an adapter.
