2. Description of the Related Art Conventionally, as a mounting structure for mounting a water tap component such as a shower stand on a mounting portion such as a top plate of a wash basin, as shown in FIG. Through the male screw portion 28 of the hydrant component 21,
A structure in which a nut 70 is screwed into the male screw portion 28 from the back surface 12 side of the installation portion 10 is generally adopted. In such a mounting structure, in order to prevent the nut 70 from being excessively tightened, to prevent the nut 70 from being loosened, and to obtain a smooth rotation of the nut 70, an annular flat plate made of rubber or the like is used. An elastic material 60 formed in
The sliding member 50 formed in a ring shape and a flat plate shape by resin or the like,
It is interposed between the installation part 10 and the nut 70. Here, the elastic member 60 and the sliding member 50 are attached to the installation portion 10.
The elastic member 60 and the sliding member 50 are arranged in this order from the side.
Hereinafter, this mounting structure is referred to as Conventional Example 1.

[0003] In the case where the installation portion is an inclined surface, the back surface of the installation portion is usually also an inclined surface, and the nut cannot be attached to such an inclined surface. As shown in FIG. 5B, a spacer 40 whose upper surface 41 is an inclined surface is interposed corresponding to the inclined surface of the back surface 12 of the installation section 10. In such a case, as disclosed in Japanese Patent Application Laid-Open No. H11-256641, an elastic material 60 is interposed on both upper and lower sides or at least one side of the spacer 40. Hereinafter, this mounting structure is referred to as Conventional Example 2.

[0004]

However, in the conventional example 1, the elastic member 60 and the sliding member 50 are arranged in the order of the elastic member 60 and the sliding member 50 from the installation part 10 side. Problems arise.

A sliding member 5 is provided between the elastic member 50 and the nut 70.
0, the rotational force of the nut 70 is difficult to be transmitted to the elastic member 60, but immediately before the nut 70 is completely tightened, the rotational force of the nut 70 is
0 to the elastic member 60. Here, the installation unit 1
Since the back surface 12 of 0 is a rough surface that has not been subjected to any processing, the frictional resistance between the installation portion 10 and the elastic member 60 is large. Therefore, while a rotational force is applied to the surface of the elastic member 60 on the nut 70 side, a force for stopping the mounting member 10 together with the surface of the installation portion 10 is applied to the elastic member 60, causing torsion. When such a twist occurs, the elastic material 60 is rapidly deteriorated by an unnecessary stress load,
The nut 70 may be inadvertently loosened without a sufficient loosening prevention effect obtained by the elastic member 60.

On the other hand, in the conventional example 2, when the elastic member 60 is interposed on the upper surface 41 side of the spacer 40, the following problem occurs.

Even if the spacer 40 rotates with the rotation of the nut 70, the spacer 40 has the inclined upper surface 41, so that the upper surface 41 follows the inclined surface of the back surface 12 of the installation portion 10. Then, the spacer 40 is automatically positioned by tightening the nut 70. However, if the elastic material 60 is interposed on the upper surface 41 side of the spacer 40, as shown in FIG. 6, even if the positional shift remains in the spacer 40, the elastic material 60 absorbs this positional shift. This impedes the automatic positioning of the spacer 40. Therefore, the tightening of the nut 70 may be completed while the spacer 40 remains misaligned. As described above, if the spacer 40 is misaligned, the spacer 40 is not tightened after the nut 70 is completely tightened.
When the nut returns to the normal position, the nut is loosened.

In the second conventional example, since the sliding member is not interposed between the spacer 40 and the nut 70, the following problem occurs.

Even if the spacer 40 is properly positioned just before the tightening of the nut 70 is completed, the nut 7
The rotational force of the nut 70 until the completion of the tightening of 0 may be transmitted to the spacer 40, and the spacer 40 may be shifted from a normal position. In particular, the spacer 40 and the nut 7
0, the elastic material 60
Since the frictional resistance of the nut 70 and the spacer 40 with respect to the above is large, the above-described problem occurs remarkably. As described above, when the spacer 40 is misaligned, the same problem as described above occurs.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a mounting structure for a water faucet component, which can surely secure a mounting state of the water faucet component. That is.

[0011]

Means for Solving the Problems To solve the above problems, first, a means adopted by the invention of claim 1 is that a hydrant component having a male screw portion is mounted on a mounting portion, and a mounting hole of the mounting portion is provided. A mounting structure of a hydrant component attached by inserting the male screw portion into the male screw portion and screwing a nut to the male screw portion from the back side of the installation portion, wherein the installation portion is provided between the installation portion and the nut. Characterized in that a sliding material having excellent slidability is interposed on the side and an elastic material having excellent elasticity is interposed on the nut side. "

By disposing the sliding member on the installation portion side and the elastic material on the nut side, the elastic member rotates smoothly with respect to the installation portion. Therefore, in the elastic material, even if a rotational force is applied to the nut side by tightening the nut, the installation portion side easily follows and rotates, and unnecessary twisting is less likely to occur.

In the present invention, the mounting portion, the sliding member,
It is not limited to the mode in which the elastic material and the nut are sequentially abutted, and various types of various materials may be provided between the installation portion and the sliding material, between the sliding material and the elastic material, or between the elastic material and the nut. An intermediate member may be interposed. Here, examples of the intermediate member include various members such as a spacer that fills a large gap between the installation portion and the nut, a branching member for branching the flow path, and the like. Also, adopting a sliding material as this intermediate member,
The nut may rotate more smoothly with respect to the installation portion.

Next, means adopted by the invention of claim 2 is:
The back surface of the installation portion is an inclined surface, and a spacer having an inclined surface corresponding to the inclined surface is interposed between the back surface of the installation portion and the sliding member. Mounting structure of the hydrant component described in the above section.

When a spacer having an inclined surface is disposed between the installation portion and the nut, in order to realize automatic positioning of the spacer, the spacer and the nut are rotated so that the spacer and the nut rotate smoothly. It is desirable to dispose a sliding member between them. And in the aspect in which the elastic material is arranged between the spacer and the nut, it is conceivable to arrange a sliding material between the elastic material and the nut. However, in this case, even if a sliding material is interposed,
Immediately before the nut is completely tightened, the transmission of the rotational force of the nut to the elastic member cannot be completely prevented, and the nut, the sliding member, and the elastic member rotate integrally. If the nut and the elastic material rotate integrally as described above, since the frictional resistance between the elastic material and the spacer is large, the spacer rotates with the rotation of the nut, and the spacer is misaligned when the nut is completely tightened. May occur.

On the other hand, in a mode in which a spacer having an inclined surface is disposed between the installation portion and the nut.
By applying the invention of the above, the sliding material is arranged on the spacer side,
The elastic material is arranged on the nut side. Therefore, even if the elastic material and the sliding material rotate integrally with the nut, the frictional resistance between the spacer and the sliding material is small, so that the spacer is easy to slide against the sliding material, and the rotational force of the nut is applied to the spacer. It becomes difficult to be transmitted. This makes it difficult for the spacer to be misaligned.

Next, means adopted by the invention of claim 3 is:
"The hydrant component having a male screw portion is inserted into the mounting hole of the mounting portion, and the nut is screwed into the male screw portion from the back surface side of the mounting portion. In the mounting structure of the hydrant component to be attached by doing, a spacer having an inclined surface corresponding to the inclined surface is arranged on the back side of the installation portion without interposing an elastic material having excellent elasticity, A sliding member having excellent slidability and an elastic material having excellent elasticity are interposed between the spacer and the nut.

In the present invention, since no elastic material is interposed between the installation portion and the spacer, the tightening by the nut is prevented from being completed while the spacer is misaligned.
In addition, since the sliding material is interposed between the spacer and the nut, the rotational force of the nut is not easily transmitted to the spacer, and the displacement of the spacer due to the tightening of the nut is less likely to occur.

Finally, the means adopted in claim 4 is that the water supply is provided on the spacer side and the elastic material is disposed on the nut side. Mounting structure of plug parts ".

In the third aspect of the present invention, the location of the sliding member and the elastic member is not limited. However, in the present invention, the sliding member is on the spacer side and the elastic member is on the nut side. The spacer can be automatically and normally positioned by tightening. The details are as described in the means of the second aspect of the invention, and the details are omitted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a specific example of a mounting structure of a hydrant component according to the present invention will be described as an example of application to a shower device 20 with reference to FIGS. This shower device 20 is suitably installed in the installation section 10 configured using a top plate of a vanity table or a sink.

The installation section 10 has a mounting hole 11 penetrating the front and back surfaces. Further, the installation portion 10 is inclined downward toward the user, so that hot water that has fallen on the surface of the installation portion 10 can easily flow to a wash ball, a sink, or the like. However, the “installation unit 10” according to each invention of the present invention.
Are not limited to those shown in this example, and include, for example, a "top plate arranged substantially horizontally", a "washroom, kitchen, or bathroom wall", a "washroom, kitchen, or bathroom counter". It may be constituted by using.

The shower device 20 includes a base 21, a slide tube 22, a shower holder 23, and a shower head 24. Among these, the base part 21 shows one specific example of the hydrant component according to the present invention, and an outer part 25 constituting an outer part and an inner mechanism formed by being screwed and fixed inside the outer part 25 are formed. And an internal mechanism 26 as a main component. The bottom surface 27 of the base 21 is provided in an inclined manner, and a male screw portion 28 projects downward from the bottom surface 27. However, the configuration of the base 21 is not limited to this example, and may be configured by a single member, for example.

The slide cylinder 22 is formed in the through hole 2 of the base 21.
9 is supported so as to be slidable in the vertical direction and rotatable in the horizontal direction.
A shower holder 23 is fixed to the upper end of the shower holder.
Further, a hose 31 is inserted into the insertion hole 30 of the slide cylinder 22 as shown by a dashed line in the drawing, and a terminal portion of the hose 31 is connected to a shower head 24 supported so as to be able to be pulled out by the shower holder 23. .

Next, a description will be given of a structure for mounting the base portion 21 to the installation portion 10. In this mounting structure, the male screw portion 28 of the base 21 is inserted into the mounting hole 11 and protrudes toward the back surface 12 of the installation portion 10. With the insertion of the male screw portion 28, the bottom surface 27 of the base 21 is
Is abutted on the surface of the installation portion 10 in a watertight manner with the interposition of As the seal member 32, for example, a sheet packing made of a resin foam or the like is employed.

On the back surface 12 side of the installation portion 10, after the spacer 40, the sliding member 50, and the elastic member 60 are mounted on the male screw portion 28 in this order, the nut 70 is screwed. ing. Here, the upper surface 41 of the spacer 40 is an inclined surface corresponding to the back surface 12 of the installation portion 10, and the lower surface of the spacer 40 is horizontal when mounted along the inclined surface of the back surface 12 of the installation portion 10. And the nut 70 can be assembled. The constituent material of the spacer 40 is not particularly limited, but, for example, metal, POM, PA, P
It is preferable to use a material such as resin having excellent strength such as C. The constituent material of the sliding member 50 is not particularly limited. For example, it is preferable to use a resin or the like having excellent self-lubricating properties such as PVC and POM. As the shape, for example, a substantially flat ring-shaped thin-walled shape with high smoothness on the front and back surfaces can be adopted. Further, the constituent material and shape of the elastic member 60 are not particularly limited.
It is possible to adopt a rubber such as R and adopt a substantially ring-shaped flat plate shape.

In this mounting structure, first, the nut 7
In the initial stage of the tightening operation of 0, the spacer 40, the sliding member 50, and the elastic member 60 rotate integrally with the nut 70. Then, as the nut 70 is tightened, the upper surface 41 of the spacer 40 follows the back surface of the installation portion 10 and the spacer 4
0 is automatically positioned. Here, the installation unit 10
Since the elastic material 60 that absorbs the positional deviation of the spacer 40 is not interposed between the spacer 40 and the spacer 40, the spacer 40 is accurately positioned. In addition, installation part 1
A sliding member (not shown) may be interposed between 0 and the spacer 40. By doing so, the back surface 12 of the installation section 10
Is not smooth, the spacer 40 rotates smoothly with respect to the installation part 10, and the positioning of the spacer 40 is performed smoothly.

Next, when the nut 70 is tightened, and immediately before the tightening is completed, the upper surface 41 of the spacer 40 abuts against the back surface 12 of the installation portion 10 correctly, and the spacer 40 is accurately positioned. When the tightening amount of the nut 70 is further increased, the sliding member 50 and the elastic member 60 rotate integrally with the nut 70, while the spacer 40 does not rotate by sliding with respect to the sliding member. As shown in FIG. 2, the tightening of the nut 70 is completed at the correct position of the spacer 40.

The mounting structure of the hydrant component according to the present invention is not limited to the above example. FIG. 3 shows another specific example, which will now be described. In another specific example, a sliding member 50 having excellent slidability, an elastic member 60 having excellent elasticity, and a second sliding member similar to the sliding member 50 are provided between the installation portion 10 and the nut 70. The moving material 51 is sequentially overlapped and interposed from the installation section 10 side. That is, the elastic member 60 has the sliding member 50 on both sides thereof.
And the second sliding member 51 in a sandwich state. In such an embodiment, the second sliding member 5
By the operation of 1, the elastic member 60 is easily rotated with respect to the nut 70. Therefore, external forces directed in opposite directions to each other are less likely to be applied to both sides of the elastic member 60, and unnecessary deformation of the elastic member 60 is further unlikely to occur.

The structure in which both surfaces of the elastic member 60 are sandwiched between the sliding members 50 and 51 is a novel structure. The present invention can also be applied to an assembly structure of a water faucet component in which an elastic material is interposed between the first water faucet component and the second water faucet component. For example, if simply interposing a sliding material on one side of the elastic material does not provide sufficient freedom of rotation between the first hydrant component and the second hydrant component, By interposing sliding materials on both sides of the elastic material,
Sufficient rotation can be obtained. Here, as the first faucet part and the second faucet part, for example, a cylindrical hub of a water outlet is rotatably fitted to the main body of the water faucet, and is rotatably spouted to the main body of the water faucet. When the water port is provided, the above-described hub, hydrant body, and the like can be exemplified.

FIG. 4 shows still another specific example of the mounting structure of the hydrant component according to the present invention. In this specific example, the sliding member 50 and the elastic member 60 are sequentially superposed and interposed between the spacer 40 and the nut 70 from the spacer 40 side.
A second sliding member 51 similar to the sliding member 50 is interposed. That is, in the present example, a plurality of sliding members 50 and 51 are interposed, for example, two or more. In the specific example shown in FIG. 4, for example, even when the spacer 40 and the sliding member 50 do not slide
The spacer 40 smoothly rotates with respect to the nut 70 due to the smooth slidability between the 0 and 51.

The structure in which a plurality of sliding members 50 and 51 are superposed is a novel structure, and is not limited to the mounting structure of the hydrant component of each of the present invention, but also to the first hydrant component which is relatively rotated. The present invention can also be applied to an assembly structure of a water faucet component in which a sliding material is interposed between the second water faucet component. For example, in the case where sufficient interposition between the first hydrant component and the second hydrant component cannot be sufficiently obtained simply by interposing a single sliding material, the sliding material is used. By superimposing a plurality of such as, for example, two sheets, sufficient freedom of rotation can be obtained. Here, as the first faucet part and the second faucet part, for example, a cylindrical hub of a water outlet is rotatably fitted to the main body of the water faucet, and is rotatably spouted to the main body of the water faucet. When the water port is provided, the above-described hub, hydrant body, and the like can be exemplified.

In each of the above embodiments, the example in which the spacer 40 is provided has been described. However, in the invention of claim 1, the spacer 40 is not necessarily required. In addition, although examples have been described in which the present invention is applied to the mounting structure of the shower device 20, the present invention can be suitably applied to other water faucet parts. For example, the faucet body of the hydrant with a stand attached to the stand,
The faucet main body of the faucet with a wall attached to the wall may be the faucet component in each of the present inventions. In addition, when a connecting pipe such as a socket is interposed when the faucet main body is fixed to an installation portion such as a base or a wall, the present invention can be applied by using the connecting pipe as a faucet part.
