A water faucet mounting adapter 37 having 33 insertion holes 36 is fixed from above in a state where the two holes 34 and 36 are communicated with each other. There is something to stop.

More specifically, as shown in FIG. 12, a faucet mounting mechanism 39 is provided with through holes 36 for hot and cold water supply pipes 32 and 33.
Are formed in the adapter 37 formed with a screw member 41 having a rotary operation head h at an upper portion thereof. A holder 42 is screwed onto the screw member 41, and a semicircular connecting member 43 is provided over the insertion ends of the screw members 41, 41, and a detent member of the holder 42 is provided over the connecting member 43 and the adapter 37. 4
In addition to the configuration in which the E-rings i and i for preventing the connection member 43 from coming off are provided at the insertion ends of the screw members 41 and 41 after the provision of the E-rings 4 and 44.

[0004] A holder 42 screwed to the screw member 41.
As shown in FIG. 13, the screw member can pass through the through hole 34 formed in the faucet mounting plate 35 from above, and as shown in FIG. With the rotation operation of 41, the screw member 41 rotates together with the screw member 41 to contact the rotation preventing member 44, and as shown in FIG. The holder 42 and the adapter 37 sandwich the faucet mounting plate 35 (FIG. 11).

If the holders 42, 42 are strongly tightened and the tightening surface pressure is not increased, the adapter 37 and, consequently, the hot and cold water mixing tap 31 will be displaced.

Further, since the line R connecting the two points of tightening by the holders 42, 42 is deviated from the center Q of the adapter, the adapter portion 37a on the opposite side is likely to be lifted up, and the water mixing tap 31 is inclined. There was a problem in that the appearance became worse.

The present invention has been made in view of such circumstances, and does not cause displacement or inclination of a faucet such as a hot and cold water mixing faucet, so that it can be easily viewed by a single worker from above the plate portion. A faucet mounting mechanism that can be mounted,
The purpose is to provide a product that can shorten the construction time.

[0009]

The technical means adopted by the present invention to achieve the above object are as follows. That is, in the invention according to claim 1, as the faucet mounting mechanism for fixing the faucet mounting adapter from above the plate portion, the adapter includes at least three holder guides that can be inserted into the through holes. At least one of the holder guides is provided at substantially equal intervals around the center of the adapter, and at least one of the holder guides is configured to be a screw member having a rotating operation head at an upper portion, and is configured to be rotatable with respect to the adapter. A holder is provided so as to be switchable between a first position passing through the through hole from above and a second position engaging with the lower surface of the faucet mounting plate with rotation.

[0010] One holder holding member for receiving and holding these holders at once is made large enough to pass through the through hole, and an insertion hole for the supply pipe is formed in the holder holding member. The holder guide formed with the screw member is screwed to the holding member, and the remaining holder guides are engaged with the holder holding member, and the screw of the holder holding member is rotated by the rotation of the holder guide formed as the screw member. The holder is lifted as it advances, and the faucet mounting plate is sandwiched between the holder and the adapter, while the contact surface between the holder holding member and the holder is moved to the second position of the holder. The adapter is formed on a slope that descends radially outward from the center of the adapter so that it is in close contact with each other in the switching state. With the rotation of the loaders is characterized the holder from the first position to the point comprising configured to switch to the second position.

According to a second aspect of the present invention, as the faucet mounting mechanism for fixing the faucet mounting adapter from above the plate portion, the adapter has at least three holder guides that can be inserted into the through holes. The holder guide is provided at substantially equal intervals around the center of the adapter, and at least one of the holder guides is formed as a screw member having a rotating operation head at an upper portion thereof, and is configured to be rotatable with respect to the adapter. A holder is provided so as to be switchable between a first state passing through the through hole from above and a second state engaging with the lower surface of the faucet mounting plate part with sliding in the radial direction from the center of the adapter. I have.

[0012] One holder holding member for receiving and holding these holders at once is made large enough to pass through the through-hole, and an insertion hole for the supply pipe is formed in the holder holding member. The holder guide formed with the screw member is screwed to the holding member, and the remaining holder guides are engaged with the holder holding member, and the screw of the holder holding member is rotated by the rotation of the holder guide formed as the screw member. The holder is lifted as it moves, and the faucet mounting plate is configured to be sandwiched by the holder and the adapter, while the contact surface between the holder holding member and the holder is moved to the second state of the holder. The adapter is formed on a slope that descends radially outward from the center of the adapter so that it is in close contact with each other in the switching state. With the slide in the radial direction from the adapter center of loaders, it is characterized the holder from the first state to that formed by configured to switch to the second state.

According to the first aspect of the present invention, the holders provided on at least three holder guides are brought into the first position by, for example, being gathered together by a finger, and the holder is inserted into the through hole of the faucet mounting plate. When the holder is fitted and passed through the through hole, the holder is rotated by the cam action between the inclined surfaces, and the holder is switched from the first position to the second position. At this time, it is possible to reciprocate the adapter as needed to apply a centrifugal force in the rotational direction to the holder, thereby ensuring that the holder is in the second position.
This is suitable for switching to a posture.

[0014] Also in the invention according to claim 2, the holders provided on at least three holder guides are brought together in the first state, for example, by gathering them together with a finger, and this holder is fitted into the through hole of the faucet mounting plate portion. While passing through the through hole, the holder slides in the radial direction from the center of the adapter due to the cam action between the inclined surfaces, and the holder switches from the first state to the second state. At this time, it is preferable to reciprocate the adapter as necessary to apply a centrifugal force in the sliding direction to the holder in order to surely switch the holder to the second state.

Here, one holder guide formed as a screw member and screwed to the holder holding member is rotated above the faucet mounting plate portion, and the holder holding member is advanced by the rotation of the holder guide. Accordingly, the holder switched to the second position in the invention according to claim 1 and the holder switched to the second state in the invention according to claim 2 are lifted at a stroke, and finally, the faucet mounting plate By holding the part between the holder and the adapter, the adapter for installing the faucet can be fixed to the faucet mounting plate from above the plate part, and if there are two or more holder guides formed with the screw member, By tightening the remaining holder guides after the faucet mounting plate is clamped, the strength of the plate can be increased.

Accordingly, in any of the first and second inventions, thereafter, the supply pipe connected to the faucet is inserted from above into the supply pipe insertion hole of the adapter, and the faucet is fixed to the adapter. Thus, a series of attachments of the faucet to the faucet mounting plate can be easily performed by a single person working above the plate, without having to sink under the sink or the like as in the conventional case.

At this time, if the number of holder guides formed with the screw member is reduced to one, the installation time for mounting the adapter is reduced by half compared to the conventional case, or the number of holder guides formed with the screw member is reduced to two or more. Thus, the strength of the plate portion is increased.

In each of the first and second inventions, the fastening points of the faucet mounting plate by the holder are at least three points at approximately equal intervals around the center of the adapter. If the pressure is the same as before, the adapter can be fixed more firmly,
The displacement of the adapter and the faucet is reliably prevented. In addition, since the center of the adapter is located within the line connecting the at least three tightening points, the faucet can be held upright without tilting. Then, it can be attached to the faucet attachment plate.
