A fixing nut 41 for fixing 35 to the mounting hole 40 of the top plate 39 and a U-shaped engaging member 38 for preventing the faucet 31 from coming off from the mounting member 35 are used. The mounting member 35 is fitted into the mounting hole 40 of the top plate portion 39 from above, and the nut 41 is screwed into the male screw 37 from below the top plate portion 39 to fix it to the top plate portion 39. When the insertion portion 32 is inserted into the attachment member 35 from above, the U-shaped engagement tool 38 that is laterally fitted to the lower end portion of the attachment member 35 under the top plate portion 39 is the engagement portion of the faucet 31. 34 is elastically engaged to prevent the faucet 31 from coming out upward, and the detent portion 33 of the faucet 31 is engaged with the detent engagement portion 36 of the mounting member 35 to prevent the faucet 31 from deactivating. I do. Accordingly, if the mounting member 35 is fixed to the top plate portion 39 in advance in a factory that manufactures a washbasin or a sink, the faucet 31 is inserted into the mounting member 35 from above the top plate portion 39 at a construction site such as a house. The faucet 31 can be attached only by itself. Further, in order to remove the faucet 31, the nut 41, which fixes the mounting member 35 to the top plate portion 39, is loosened from below the top plate portion 39 to pull out the engagement tool 38, and then the water faucet 31 is pulled up. Just do it.

[0003]

However, in the above-mentioned conventional one, when both the mounting member and the water faucet are mounted at the construction site or the water faucet is removed, the mounting member is fixed or removed in the same manner as in the conventional case. Since it is necessary to dig into a narrow space under the top plate even in a cramped posture, the workability is poor and the mounting work is troublesome. The same applies to the mounting and removal of the faucet on the wall surface.

An object of the present invention is to solve the above problems, and to carry out all the work relating to the installation and removal of the faucet without sinking under the wash basin or the like, the surface of the plate or the wall such as the top plate. It is an object of the present invention to provide a faucet mounting device that can be easily operated only from the side.

[0005]

In order to achieve the above-mentioned object, the faucet mounting device of the present invention has an elastic projection from the outer periphery to the lower part of the outer periphery fitted into the mounting hole of the plate material. A cylindrical mounting member that has a habit and has a retaining piece that engages with the lower opening edge of the mounting hole, and has a mounting male screw portion formed on the upper part of the outer periphery, and is screwed to the mounting male screw portion of this mounting member. A fixing nut that sandwiches the plate member between the retaining member and the fixing member to fix the mounting member to the plate member, and a fixing nut that is fitted to the outer periphery of the lower portion of the faucet body so as to be rotatable only and is in the fixed state. The main feature is that the faucet body is provided with a coupling nut for abuttingly coupling the faucet body to the mounting member by screwing.

In this case, it is preferable that the mounting member and the faucet body are provided with rotation preventing means for preventing the faucet body from rotating with respect to the mounting member in a state where they are butted against each other.

It is preferable that the coupling nut is screwed onto the outer periphery of the fixed nut and covers the coupling portion between the mounting member including the fixed nut and the faucet body.

[0008] It is more preferable to provide an adapter that is screwed to the upper portion of the male thread portion for attachment of the attachment member so as to be adjustable in height and forms an abutting portion with the faucet body.

[0009]

[Function] When the mounting member is pushed into the mounting hole of the top plate from above,
Since the retaining piece of the mounting member hits the peripheral edge of the mounting hole and is retracted inward, the mounting member is easily inserted into the mounting hole. When the retaining piece slips through the mounting hole by inserting the mounting member into the mounting hole, the retaining piece restores to the protruding state to the lower outer periphery of the mounting member and engages with the lower opening edge of the mounting hole. The member is in a state in which it cannot be pulled out upward. When the fixing nut is screwed and tightened from above to the male screw portion for mounting formed on the upper part of the outer periphery of the mounting member, the plate material is sandwiched between the fixing nut and the retaining piece to integrate them. As a result, the attachment member can be fixed to the plate member only by the work from above the plate member. If you place the faucet body on this mounting member and screw the coupling nut that is fitted on the outer circumference of the lower part of the faucet so that it can only rotate, screw it onto the fixing nut that fixes the mounting member on the plate material and tighten it. , The faucet body is pulled toward the mounting member side, and both are butt-joined and integrated. As a result, the attachment of the faucet body to the plate member using the attachment member can be achieved only by the work from above the plate member.

In the structure in which the mounting member and the faucet body are provided with rotation preventing means for preventing the faucet body from rotating with respect to the mounting member in the abutting state, in order to join the faucet body to the mounting member, When the coupling nut is screwed onto the fixed nut, the rotation preventing means of the mounting member and the faucet body works, so that the faucet body can be prevented from rotating and changing its direction.

In the structure in which the coupling nut is screwed onto the outer periphery of the fixed nut and covers the coupling portion between the mounting member including the fixed nut and the faucet body, the portion where the mounting member is fixed to the plate member and the plate member are fixed. The exterior of the portion where the faucet body is butt-joined to the mounting member can be trimmed with one coupling nut to adjust the appearance.

In this case, in the structure provided with the adapter which is screwed onto the upper part of the male screw part for mounting of the mounting member so as to adjust the height and forms a butting part with the faucet body, the mounting member is mounted in the mounting hole of the plate member. The amount of protrusion on the plate when fixed is
Even if it varies depending on the thickness of the plate material, by adjusting the screwing height of the adapter to the upper part of the mounting member, it is possible to set the required height from the top surface of the plate material to the abutting part with the faucet body provided by the adapter. If the connecting nut is placed in a predetermined butt joint state with the faucet body on the mounting member without changing the mounting position of the joint nut to the faucet body and the dimensions of the joint nut, the lower end of the joint nut is It is possible to make a predetermined close contact with the upper surface.

A plurality of substantially U-shaped cut grooves 4 are formed on the peripheral wall of the mounting member 3 at equal intervals in the circumferential direction, and a retaining piece 5 is provided which is divided into a part of the peripheral wall by the cut grooves 4.

The retaining piece 5 is always projected to the lower part of the outer periphery of the mounting member 3 and has an outer surface as a tapered surface 6 which is inclined downward and inward. On the outer peripheral surface of the upper portion of the mounting member 3, a male screw portion 7 for mounting to which a fixing nut 9 for fixing the mounting member 3 to the top plate 1 from above is screwed is formed, and on the inner peripheral surface of the upper portion, a faucet body 11 is formed. A female spline portion 8 for preventing rotation is engraved.

The faucet body 11 has a cylindrical joint portion 12 formed at the lower end of the faucet body 11, and as shown in FIGS. 1, 2 and 6, a water supply pipe 20 communicating with a water supply source and a hot water supply communicating with a hot water supply source. The pipe 21 is connected. A male spline portion 13 which is fitted to the female spline portion 8 of the mounting member 3 and constitutes the rotation preventing means A is engraved on the outer peripheral surface of the lower portion of the coupling portion 12. A packing 17 and a split ring 18 are interposed on the outer periphery of the lower portion of the faucet body 11 as shown in FIG. 2, and the coupling nut 14 can rotate only and is mounted so as to cover the coupling portion 12.
The split ring 18 is elastically fitted into the outer peripheral groove 12a of the coupling portion 12 and partially protrudes out of the groove 12a.
The coupling nut 14 is retained so as to be rotatable with respect to the coupling portion 12 by being caught by the collar portion 15 which annularly projects inward of the coupling nut 14. A male screw portion 10 for fixing the outer periphery of the fixing nut 9.
A female screw portion 16 that is screwed into is formed. Packing 1
Reference numeral 7 seals the fitting portion between the coupling nut 14 and the coupling portion 12.

The second embodiment of the present invention shown in FIGS. 7 to 9 employs a rotation preventing means A different from that of the first embodiment. In this embodiment, a plurality of grooves 8a are formed in the upper inner peripheral surface of the mounting member 3a in place of the female spline portion, in this embodiment, two grooves 8a are formed, and a male spline portion is formed in the joint portion 12c of the faucet body 11. Instead, two protrusions 13a are provided, and when the faucet body 11 is coupled to the mounting member 3a, the protrusions 13a engage with the respective grooves 8a so that the faucet body 11 can be rotated with respect to the mounting member 3a. I try to prevent it.

The faucet body 11 can be attached without providing these rotation preventing means A. However, if the anti-rotation means A is provided, the faucet body 11 does not rotate with respect to the mounting member, so that the orientation can be kept constant, so that the mounting work can be performed quickly.

In these first and second embodiments, the procedure for attaching the faucet body 11 to the top plate 1 of the sink or sink installed at the construction site of a house will be described.
Is pushed into the mounting hole 2 of the top plate 1 from above. Then, in the retaining piece 5 of the mounting member 3, the tapered flat surface 6 hits the upper opening edge of the mounting hole 2 and is elastically deformed inward, so that the mounting member 3 can be easily inserted into the mounting hole 2. it can. When the retaining piece 5 slips through the mounting hole 2, the retaining member 5 is restored to the projecting state to the outer periphery of the mounting member 3 and is caught by the lower opening edge of the mounting hole 2 to prevent the mounting member 3 from coming out upward. Next, after fitting the packing 19 to the upper end of the mounting member 3,
The fixing nut 9 is screwed onto the mounting male screw portion 7 of the mounting member 3 from above the top plate 1 to tighten the fixing nut 9.
The top plate 1 is sandwiched between and the retaining piece 5 to integrate them. As a result, the attachment member 3 can be attached to the top plate 1 only by an operation from above the top plate 1. The faucet body 11 is arranged on the mounting member 3, and the faucet body 11 is formed in the coupling portion 12 below the faucet body 11 so that the faucet body 11 faces the front and does not rotate with respect to the mounting member 3. The spline portion 13 is fitted to the female spline portion 8 of the mounting member 3. Hold the faucet body 11 in this state with one hand and use a tool with the other hand to turn the female thread portion 16 of the coupling nut 14 capable of only rotating the faucet body 11 into the male thread portion for fixing the fixing nut 9. When screwed into 10 and tightened, the faucet body 11 is pulled toward the mounting member 3 side, and both are abutted and coupled to be integrated. By this, the faucet body 1
The mounting using the mounting member 3 of No. 1 can be achieved only by the work from the upper side of the top plate 1. Therefore, the top plate 1
No work is required from below. Such a characteristic is also exhibited when a faucet is attached to a wall material.

In order to remove the faucet body 11 from the top plate 1, contrary to the above, the coupling nut 14 is rotated in the screw returning direction, the coupling nut 14 is disengaged from the fixed nut 9, and then the faucet body 11 is removed. Just pull it up.

The retaining piece 5 is integrally formed by utilizing the peripheral wall of the mounting member 3, and has a notch 5a formed in the base portion thereof to facilitate the elastic deformation. Such a structure is convenient when the mounting member 3 is a synthetic resin. The retaining piece 5 may be provided separately from the mounting member 3 by urging the retaining piece 5 in the protruding direction with a spring. This is suitable when the mounting member 3 is made of metal.

It is preferable that there are a plurality of retaining pieces 5 for the purpose of stabilizing the attachment, but the invention is not limited to this. Coupling nut 14
Covers the portion where the mounting member 3 is fixed to the top plate 1 and the connecting portion 12 of the faucet body 11 to the mounting member 3, so that these are exteriorized and the appearance is adjusted. However, it is not limited to this. In this case, the screwing portion of the coupling nut 14 to the fixed nut 9 is not limited to the outer periphery.

FIG. 10 shows a third embodiment of the present invention. In this embodiment, an adapter 22 is provided on the mounting male screw portion 7 of the mounting member 3 and is screwed subsequently to the fixing nut 9.

When the faucet body 11 is butt-joined to the mounting member 3 by adjusting the screwing amount of the adapter 22 into the mounting male screw portion 7 according to the difference in the thickness B of the top plate 1 of each washbasin. The distance L between the abutting portion D of the and the top plate 1 becomes constant regardless of the difference in the thickness B, and the mounting position of the coupling nut 14 on the faucet body 11 and the coupling nut 1
4 does not change the dimension H of the connecting nut 14 and the faucet body 1
The lower end of the coupling nut 14 is brought into a predetermined contact state with the upper surface of the top plate 1 when the mounting nut 1 is brought into a predetermined butt joint state with the mounting member 3. This makes the coupling nut 1
Although the outer cover 4 covers and covers the joint portion 12, the fixing nut 9 and the packing 19, there is no gap C between the top plate 1 and the top plate 1 as shown in FIG.

That is, in the first embodiment, the distance L between the faucet body 11 and the top plate 1 of the abutment portion 11 formed by the mounting member 3 differs depending on the thickness of the top plate 1. Therefore, when the attachment position of the faucet body 11 to the coupling nut 14 and the dimension H of the coupling nut 14 are kept constant, when the faucet body 11 is butt-joined to the mounting member 3, the coupling nut 14 and A gap C is formed between the top plate 1 and the fixing nut 9 and the packing 19 are exposed from the gap C. On the contrary, before the butt joint is completed, the joint nut 1
4 also comes into contact with the top plate 1 and the butt joint cannot be completed. The present embodiment can eliminate these disadvantages.
