[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faucet mounting structure in which a faucet is installed via a branch fitting instead of directly connecting a faucet to a supply pipe provided on a wall of a building.

[0002]

2. Description of the Related Art Generally, a hot-water mixer tap for fixing a wall is connected to a water supply pipe and a supply pipe for hot water supply which are piped into a wall, thereby fixing a main body and simultaneously connecting a flow path. . And for connection with these supply pipes, leg pipes for water supply and hot water supply are provided at the back of the main body, whereby the main body is positioned and fixed to the wall.

On the other hand, facilities around various faucets have recently been expanded, and for example, when used as faucets for kitchens, water purifiers have been widely provided.
This water purifier includes a simple type that detachably attaches to the tip of a water faucet pipe of a faucet and filters water flowing out, and a water purifier having a relatively large capacity provided with a dedicated water supply pipe connected thereto.

[0004]

When such a water purifier is added, for example, a branch fitting is connected to a leg pipe of a hot water mixer tap so as to distribute a flow path between the main body side of the hot water mixer tap and the water purifier side. In this case, it is not necessary to newly provide a pipe on the building side, so that the construction is simplified. In this case, the branch fitting is connected at one end thereof to the leg pipe so that its position is fixed to the wall and also to the main body of the hot and cold mixing tap.

[0005] On the other hand, the water purifier or other faucet which is to be added is a fixture itself, so that it is necessary to fix the branch fixture to a wall in order to stabilize the branch fixture.
However, since the work is attached to the existing hot and cold water mixing tap, it takes time to position the branch metal fittings. In addition, since the amount of the water mixing tap protruding from the wall varies depending on the site, the dimensional relationship with the hot water mixing tap side when fixing the branch metal fitting to the wall may be inconsistent. In this case,
The branch metal fitting will have a posture in a direction approaching the wall side or a direction protruding forward. For this reason, the connection with the leg pipe becomes poor, causing water leakage, or the branch fitting is inclined with respect to the wall, so that a gap is formed between the back and the wall.

As described above, when the branch metal fitting is used, the positioning and the posture of the wall cannot be sufficiently performed, so that not only the work is troublesome but also the piping is defective.

The problem to be solved in the present invention is to facilitate the positioning of the branch fitting and the adjustment of the position of the branch fitting when the faucet is provided to the existing pipe via the branch fitting.

[0008]

According to the present invention, one end of a branch metal fitting is connected to a leg pipe connecting between a supply pipe provided on a wall of a building and a faucet body, and the other end of the branch metal fitting is connected. A connecting seat for communicating and connecting a faucet to the wall and fixing the connecting seat to the wall, wherein the faucet penetrates the connecting seat from the front side and protrudes toward the wall and the amount of protrusion An adjuster pin is provided which can be adjusted from the front side, and a screw is provided to penetrate the connection seat from the front side and screw it into the wall.

[0009]

[Function] By adjusting the adjuster pin provided on the connection seat,
The protrusion amount of the adjuster pin from the rear surface of the connection seat changes, and the distance between the wall and the rear surface of the connection seat can be changed by abutting the tip of the adjuster pin against the wall. Therefore, it is possible to adjust and set the posture of the branch fitting with respect to the supply pipe and the wall. Further, when the tip of the adjuster pin is pressed against the wall, the branch metal fitting is brought into a state of being temporarily fixed to the wall. For this reason, it becomes possible to position the connection seat with respect to the supply pipe before fixing with the screw.

A water purifier 4 is provided in front of the front end of the main pipe 6.
Is provided coaxially with the sleeve 11. The connection seat 14 has a cylindrical shape with a circular cross section with an open front end, and is formed to be recessed to the rear side as shown in the figure. Then, a connection port 14a communicating with the internal flow path of the main pipe 6 is opened at the center of the connection seat 14, and the connection pipe 4a protruding from the back of the water purifier 4 is screwed into the connection port 14a to fix the water purifier 4. The water purifier 4 contains a replaceable filter therein, and has a configuration including a handle 4b for opening and closing a flow path and a water discharge pipe 4c as shown in FIG.

The procedure for newly installing the water purifier 4 with the branch fitting 5 using the leg pipe 2 of the main body 1 of the existing hot and cold water mixing tap is as follows.

First, a bushing for attaching a water stopcock is removed from the existing leg pipe 2. As a result, as shown in FIG. 3, the leg tube 2 is in a state where the mounting opening 2c is open to the front. On the other hand, an assembly is prepared in which the bushing 7 is integrated with the base end side of the main pipe 6 to form an integral body, and the spindle 9 is inserted into the bushing 7 by the mounting seat 8. Then, of this assembly, the bushing 7 is screwed into the female screw 2c-1 of the mounting opening 2c and fixed. In this fixing operation, the peripheral surface on the front end side of the bushing 7 may be used as a tool hook. Then, the cover 10 is integrated with the bushing 7 by screw connection, and the groove 9 of the spindle 9 is formed.
By turning a with a screwdriver, the valve opening between the packing 9b and the water shutoff valve seat 2d is adjusted.

Next, the main pipe 6 is fixed to the wall 60 by screws 12 provided on the sleeve 11 on the tip side. Before the fixing, the position of the water purifier 4 is set. That is, since the base end of the main pipe 6 is rotatable around the bushing 7, the posture can be changed around the bushing 7 as shown by an arrow in FIG. Therefore, the position of the tip of the main pipe 6 is also changed, and the position of the water purifier 4 can be selected so that the positional relationship with the main body 1 and the sink of the hot and cold water mixing tap becomes appropriate.

When such a position setting is completed, the amount of protrusion of the main pipe 6 to the front side with respect to the wall 60 is determined by the main body 1 of the hot and cold water mixing tap.
It is adjusted by the adjuster pin 13 so as to fit the side. This is a method of adjusting the distance from the wall 60 so that the position of the main pipe 6 and the connection point with the leg pipe 2 are not distorted by rotating the groove 13a of the adjuster pin 13 with a screwdriver. Do. When the screw 12 is passed through the sleeve 11 and screwed into the wall 60, the main pipe 6 is supported at its base end by the leg pipe 2 and its tip is restrained by the screw 12, and is stably fixed to the wall 60 together with the leg pipe 2. Is done. Thereafter, the cover 11a is rotated so that the rear surface thereof is exactly against the wall 60.

As described above, the posture of the branch fitting 5 with respect to the wall 60 can be adjusted only by turning the adjuster pin 13 from the front of the branch fitting 5 with a screwdriver. For this reason, the posture of the branch metal fitting 5 can be set in accordance with the distance between the connection point between the base end of the main pipe 6 and the leg pipe 2 and the wall 60, and the arrangement can be easily set parallel to the wall 60. . Therefore, no excessive force is applied to the joint portion with the leg pipe 2 or uneven contact is caused, water leakage after construction is prevented, and the branch fitting 5 is also stably fixed to the wall 60. Can be.

Next, the connection pipe 4a at the back of the water purifier 4 is screwed into the connection port 14a of the connection seat 14 and fixed in a correct posture as shown in FIG. Thereby, the flow path on the downstream side of the water stop valve seat 2d in the leg pipe 2 can be connected to the water purifier 4 using the main pipe 6 as a joint.

In this construction, since the main pipe 6 of the branch fitting 5 is rotatable around the bushing 7, the fixing point of the water purifier 4 can be changed as described above. The setting and temporary fixing of the branch metal fittings 5 including the case of the position change can be easily performed by using the adjuster pins 13.
That is, after the main pipe 6 is connected to the leg pipe 2 side and the adjuster pin 13 is moved toward the wall 60 and the buffer 13b at the tip of the adjuster pin 13 is brought into contact with the wall 60 when the overall posture of the branch fitting 5 is determined. The branch fitting 5 is restrained on the wall 60 side by the pressing force between the body 13b and the wall 60. Therefore, if the screw 12 is screwed into the wall 60 after the posture of the branch metal fitting 5 is temporarily determined by the adjuster pin 13, the work can be performed with one hand and the construction can be simplified. Further, even after the position is temporarily determined by the adjuster pin 13, the posture can be finely adjusted by turning the branch metal fitting 5 upward or downward, and highly accurate construction can be performed.

Further, if the position of the branch metal fitting 5 is determined by the adjuster pin 13, even if the screw 12 is screwed in hard, it does not move further toward the wall 60 side. Therefore, a large load is not applied to the distal end side of the branch metal fitting 5, and there is no possibility of breakage.

In the embodiment, the leg pipe of the hot and cold water mixing tap is an example of a supply pipe on the building side. However, it is of course possible to connect a branch fitting to a supply pipe for a single faucet projecting from a wall. It is.

[0029]

According to the present invention, the position and position of the faucet can be easily adjusted with respect to the existing pipes and walls on the building side by adjusting the adjuster pins provided on the connecting seat. For this reason, water leakage is prevented without causing distortion at the connection portion with the existing pipe, and construction can be performed such that the back of the branch fitting is also brought into close contact with the wall. Also, since the branch fitting can be temporarily fixed by pressing the adjuster pin against the wall, fine adjustment of the posture of the branch fitting and fixing work with screws can be easily performed.
