BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a structure for mounting a spout in a faucet device. [Problems to be Solved by Conventional Techniques and Inventions] As one type of faucet device, a handle 100 and a spout 102 are exposed on a mounting surface 104 as shown in FIG. There is a type in which a main body including a water passage portion, a valve portion, a hot water mixing portion, etc. is embedded in the mounting surface 104. In this case, the spout 102 is connected to the connection fitting 10
6 is fixed at the same time as being connected to the mounting surface 104.

FIG. 4B shows a specific structure thereof. As shown in the figure, here, the tubular connecting fitting 10 is used.
6 is a male screw formed on the outer peripheral surface of the mounting surface 10
4 Socket portion 108 embedded inside (see FIG. 4 (A))
The tip end is projected from the mounting surface 104 by screwing into, and the base end part of the water discharge port 102 is fitted to this projection part.

Here, the spout 10 for the connection fitting 106 is provided.
The fitting amount of 2 is the flange 11 formed on the connection fitting 106.
It is defined by the contact of the step 112 on the side of the water outlet 102 with respect to zero.

Further, in this mounting structure, the screw 114 screwed into the water outlet 102 is brought into contact with the tapered surface 116 formed on the connection fitting 106 to prevent the water outlet from coming off.
Further, the position of the spout 102 in the rotational direction is defined by the pin 118 inserted so as to straddle the mounting surface 104 side and the spout 102 side.

[0005]

By the way, when installing the faucet metal fitting, it is inevitable that some variation occurs in the mounting position and the like at the time of construction. Therefore, in the above structure, the socket portion inside the mounting surface 104 is inevitable. When the embedding position of 108 is shallow, the flange 110 of the connection fitting 106 is in a state of being lifted from the mounting surface 104, and thus the spout 10
2 The lower end also floats above the mounting surface 104.

Further, in the case of this mounting structure, since the spout 102 is prevented from rotating by inserting the pin 118, it is necessary to increase the wall thickness of the spout 102 accordingly.
Therefore, there is an inconvenience that the outer diameter of the water outlet 102 becomes large.

[0007]

The present invention has been made to solve the above problems, and the gist thereof is the protruding portion of the connecting member provided with the tip end side protruding on the mounting surface. In the attachment structure of the water outlet in the faucet device for connecting the base end side of the water outlet to the mounting surface and fixing the water outlet to the mounting surface, at least a portion of the connecting member that is projected from the mounting surface is a cylinder. In addition to providing a male screw on the outer peripheral surface formed in a shape, a nut provided with a flange protruding outward in the radial direction is screwed into the male screw, and the flange is at a predetermined height from the mounting surface. While fixing the nut non-rotatably to the connecting member,
The outer end of the water spout is fitted onto the connection member so that the nut is inserted into the recess on the proximal end side of the spout, and the tip end of the engaging projection provided so as to penetrate the pipe wall of the water spout. While making contact with the lower surface of the flange to define the axial position of the water spout base end and preventing the spout from coming out, a rotation blocking means is provided across the nut and the water spout, and the rotation blocking means causes the spout to stop. The purpose is to define the rotation angle position of the water outlet.

[Operation and Effect of Invention] As described above, in the present invention, the flange of the nut screwed to the male screw on the outer peripheral surface of the connecting member and the engaging projection provided so as to penetrate the pipe wall of the water outlet. Engagement of the water discharge port prevents the water discharge port from being pulled out, that is, defines the axial position of the water discharge port base end.

In the mounting structure of the present invention, even if the faucet body is embedded deeper than the standard embedding position inside the mounting surface or, conversely, shallowly due to variations in construction, a male screw on the outer peripheral surface of the connecting member is formed. By adjusting the screwing amount of the nut with respect to, the flange of the nut can be always positioned at a constant height above the mounting surface.

Therefore, the water discharge port can be firmly fixed on the mounting surface by the engagement of the flange of the nut and the engaging projection without the base end surface of the water discharge port being lifted from the mounting surface.

Embodiments of the present invention will now be described in detail with reference to the drawings. In FIG. 1, reference numeral 10 denotes a water outlet which is attached in a state in which the base end is in contact with the mounting surface 11. A thick portion 12 is formed on the base end side, and a recess also serving as a water passage is formed inside the thick portion 12. 14 is formed.

Reference numeral 16 denotes a socket metal fitting embedded in the mounting surface 11, which is a female screw hole 18 for screwing and fixing a pipe end portion of a water pipe through which water or hot water flowing out through a valve portion passes.
On the side. Further, a female screw tube 20 is provided on the upper surface, and the base end portion of the connection fitting 22 is screwed and fixed therein.

The connection fitting 22 is a tubular member having a water passage 24 inside, and the socket fitting 16 is provided from the upper end thereof.
A male screw 26 is formed on the outer peripheral surface of the threaded portion.

A hexagon nut 28 with a flange is screwed onto the male screw 26. The nut 28 has a large-diameter annular flange 30 protruding outward in the radial direction at the upper end as shown in FIG. 2, and has a female thread so as to penetrate the pipe wall at two opposite positions. A hole 32 is provided in which a set screw 34 is screwed. Set screw 34
Has a sharp tip, and the tip of the
The nut 28 is non-rotatably fixed by being pressed against the outer peripheral surface of 2.

A large-diameter second recess 36 is formed on the base end side of the water discharge port 10, and a nut 28 is accommodated therein. A female screw hole 38 is formed in the peripheral wall portion of the second recess 36 so as to pass through the peripheral wall portion, and a rotation preventing screw 40 is screwed into the female screw hole 38. The screw 40 defines the position of the spout 10 in the rotation direction by stopping the rotation of the spout 10 by bringing its tip into contact with any of the six engaging surfaces 42 (see FIG. 2B) of the nut 28.

Further, by engaging the tip of the screw 40 with the lower surface of the flange 30 of the nut 28, the base end of the spout 10 is prevented from being pulled out and the axial position is defined, that is, the position perpendicular to the mounting surface 11. It acts to define the.

In the case of the mounting structure of this embodiment, the vertical mounting position of the spout 10 is defined by the position of the nut 28. The position of the nut 28 can be always set to a constant height above the mounting surface 11 by adjusting the screwing amount with respect to the connection fitting 22 regardless of the embedded depth of the socket fitting 16.

That is, as shown in FIG. 3A, for example, when the embedding depth 1 of the socket fitting 16 is shallower than the predetermined standard depth, the nut 28 is attached by increasing the screwing amount of the nut 28. The height from the surface 11, strictly speaking, the height h from the mounting surface 11 of the lower surface of the flange 30 can be set to a fixed height, and as shown in FIG. When the insertion depth 1 is deeper than the standard depth, the height h from the mounting surface 11 can be made constant by reducing the screwing amount of the nut 28.

Therefore, according to this structure, the socket fitting 1
The spout 10 can be always mounted on the mounting surface 11 at a desired position regardless of the embedding depth of 6.

The procedure for attaching the spout 10 is as follows. First, the nut 28 is attached to the connecting fitting 22 so that the height h from the mounting surface 11 becomes the above-mentioned constant height in accordance with the embedded depth of the socket fitting 16. Adjust the screw-in amount and then set screw 34
Is screwed in to fix the nut 28 to the connection fitting 22 in a non-rotatable manner. The nut 28 can be fixed by an adhesive.

After fixing the nut 28 to the connection fitting 22,
Next, the water outlet 10 is fitted to the connection fitting 22, and the base end face is brought into contact with the mounting face 11. After that, with the rotation angle position of the water discharge port 10 aligned with a predetermined position, the screw 40 is screwed in
0 is strongly screwed into the female screw hole 38 and the tip is pressed against the engaging surface 42 of the nut 28 to determine the rotation angle position of the water outlet 10, and the tip of the screw 40 is engaged with the lower surface of the flange 30 of the nut 28 to discharge the water. Make 10 stoppers.

In the mounting structure of this embodiment, the screw 40 screwed into the pipe wall of the spout 10 and the engaging surface 42 of the nut 28.
The water outlet 10 is prevented from rotating based on its engagement with, that is, the rotation angle position is defined. Therefore, it is necessary to increase the wall thickness of the water outlet 10 so as to fix the position by inserting the pin. There is no. This has the advantage that the outer diameter of the water discharge port 10 can be reduced.

The embodiment of the present invention has been described in detail above, but this is merely an example, and the present invention can also be provided with a socket fitting integrally as a part of the connecting fitting, for example.
It is also possible to screw the screw 40 into the water discharge port 10 at two positions so as to prevent the water discharge port 10 from rotating and coming off.

In addition, the present invention can be applied to various forms of faucet devices other than the above examples, and various modifications can be made based on the knowledge of those skilled in the art without departing from the spirit of the invention. It can be configured in an added form.
