Description

  The present invention relates to a hose housing faucet mounting structure in which a water discharge head can be pulled out together with a flexible hose, and more particularly to a mounting structure using a fixture seated on the back surface of a mounting base such as a counter.

As a faucet mounting structure, a structure using a horseshoe-shaped fixing bracket (fixing tool) seated on the back surface of a counter (mounting base) has been widely practiced.
As a mounting structure using this horseshoe-shaped fixing bracket, a conventional fixing shaft body is extended from a faucet body that stands up from a counter, and is inserted into a mounting hole so as to penetrate the counter downward. Insert the fixing shaft body through the insertion hole of the horseshoe-shaped fixing bracket on the lower side of the counter, and screw the tightening nut to the external thread on the outer peripheral surface of the fixing shaft body on the lower side of the fixing bracket, Then, the fixing metal fitting is fastened to the back of the counter by screwing the tightening nut, and the faucet body is attached and fixed to the counter via the fixing shaft.

By the way, as a kind of faucet, there is a hose storage faucet that can hold the water discharge head with a flexible hose by a holder part of the faucet body, and it has been widely used as a kitchen faucet. ing.
However, in this hose storage faucet, it is necessary to pass the hose connected to the water discharge head through the counter mounting hole so as to penetrate the counter, and the mounting structure using the horseshoe-shaped fixing bracket is applied. It is difficult and not generally done.

  In the faucet mounting structure using a horseshoe-shaped fixing bracket, a supply pipe (water supply pipe, hot water supply) for supplying water and hot water to the faucet body in the space formed between the pair of arms of the fixing bracket The faucet is attached so that the mixed water from the faucet body flows out, and in addition to the supply pipe and the outflow pipe, This is because it is difficult to secure a space for passing a thick water hose in the space between the pair of arms of the fixing bracket.

  Therefore, by extending the outflow pipe through which the mixed water from the hot water mixing section of the faucet body passes through the counter to the lower side and using it as a fixing shaft body, the faucet can be used with a horseshoe-shaped fixing bracket. The water faucet mounting structure is designed to be fixed to the counter in the following Patent Document 1 and Patent Document 2.

However, in the case of this mounting structure, when the water outlet pipe is fixed to the counter with a fixing bracket as a fixing shaft body and the faucet body is attached and fixed, a tightening force is applied to the outlet pipe. There is a possibility that an unreasonable force is locally applied to the root part or other part of the faucet body connected to the faucet body, damaging the outflow pipe as a water conduit or causing water leakage.
This problem is also a problem that can occur when the faucet is attached to an attachment base other than the counter.

Effects and effects of the invention

  As described above, the present invention uses a hose guide tube that forms a hollow shaft body as a non-water-permeable tube for moving and guiding a hose as a fixing shaft body, which is fixed to a mounting base by a fixture, and is attached to a faucet body. It is intended to be fixed.

In the present invention, the hose guide tube is also configured to serve as a faucet fixing shaft, and the faucet is attached. Therefore, when a dedicated fixing shaft is provided separately from the hose guide tube Compared to the above, in addition to reducing the number of necessary members, it is not necessary to secure a space for a dedicated fixing shaft in the fixture.
Accordingly, a space for passing the hose can be easily secured in the fixture, and a dedicated fixing shaft body can be omitted, so that the mounting portion of the faucet by the fixture can be made compact.
In addition, in this invention, things, such as a semicircle other than a horseshoe shape, can be employ | adopted as a fixture.

  In addition, in the present invention, since the piping member for water passage is not used as a fixing shaft body, when the fixing member is fixed, an excessive force is applied to the piping member to cause damage or further leakage. Can be solved together.

  In the present invention, the fixing tool itself is used as a tightening nut, and this is not screwed into the male screw on the outer peripheral surface of the hose guide tube to fix the hose guide tube to the mounting base. The attaching nut is screwed onto the male screw on the outer peripheral surface of the hose guide tube at the lower side of the fixing tool, and the fixing tool is fastened to the back surface of the mounting base with the fixing nut.

  In the present invention, an auxiliary guide pipe having a diameter larger than that of the hose guide pipe is connected to the lower side of the mounting base so that the auxiliary guide pipe projects downward from the hose guide pipe. An auxiliary guide tube assists in guiding the hose in and out.

The hose guide tube is required to penetrate the mounting hole and the fixture of the mounting base, and therefore the hose guide tube cannot have a large diameter.
In this case, when the hose is put in and out, there is a problem that the outer surface of the hose is caught or rubbed particularly with respect to the lower end of the hose guide tube, and further, noise is generated at that time.

  In particular, the hose used in this kind of water faucet has a shape in which the outer surface of an elastic tube such as rubber is covered with a metal tube having a bellows shape, and the metal tube having the bellows shape is a hose guide tube. It is easy to generate an unpleasant noise such as “jumble” when entering and exiting the hose guide tube through the lower end of the tube.

  However, by connecting an auxiliary guide pipe having a diameter larger than that of the hose guide pipe to the hose guide pipe on the lower side of the mounting base, the auxiliary guide pipe assists in guiding the hose in and out, It becomes possible to avoid the above problems satisfactorily.

In the present invention, the above-described tightening nut is also configured so as to also serve as the auxiliary guide tube.
By doing so, the number of parts required for faucet installation can be reduced, the number of man-hours for installation can be reduced, the mounting workability is improved, and the lower part of the mounting base in the faucet mounting structure The structure can be simplified, and this can be made compact.

In this case, it is desirable to provide a guide portion having an annular shape in the circumferential direction and bulging inwardly at the lower end portion of the auxiliary guide tube (claim 2).
It is difficult to provide such a guide part in the hose guide pipe itself, which is difficult to increase the pipe diameter, but if it is an auxiliary guide pipe having a pipe diameter larger than the hose guide pipe, it is not possible to provide such a guide part. By providing such a guide portion, it is possible to smoothly move the hose into and out of the auxiliary guide tube while avoiding the hose catching or rubbing on the auxiliary guide tube or abnormal noise at that time. It becomes possible to guide to.
