[Industrial applications]

 The present invention relates to a faucet mounting structure in which a faucet is installed directly through a branch metal fitting, instead of directly connecting the faucet to a supply pipe laid on a wall of a building.

[0002]

[Prior Art]

 A hot and cold water mixing tap for fixing a wall is generally one that fixes the main body by connecting it to each of the water supply pipe and the supply pipe for hot water supply that are piped in the wall, and at the same time connects the flow path. Then, 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 types of 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 removes water that flows freely by detaching it from the end of the water discharge pipe of the faucet, and a relatively large capacity that has a dedicated water supply pipe and is connected to it.

[0004]

[Problems to be solved by the device]

 When adding such a water purifier, for example, if a branch fitting is connected to the leg pipe of the hot and cold water mixing tap and the flow path is divided between the main body of the hot and cold water mixing tap and the water purifier side, the piping on the building side Since there is no need to newly install, construction becomes easy. In this case, since the one end of the branch metal fitting is communicatively connected to the leg pipe, its position is fixed to both the wall and the main body of the hot and cold water mixing tap.

On the other hand, in the water purifier or other faucet to be added, the branch fitting itself serves as a fixing tool. Therefore, it is necessary to fix the branch fitting to the wall in order to stabilize it. Since this work will be attached to the existing hot and cold water mixing tap, it will take time and effort to position the branch fittings. Also, the amount of protrusion of the hot and cold water mixer from the wall varies depending on the site, so the dimensional relationship with the hot and cold water mixer may not match when the branch fitting is fixed to the wall. In this case, the branch fitting is in a posture of approaching the wall side or projecting forward. For this reason, the connection with the leg pipe is poor and water leakage occurs, and since the branch fitting is in an inclined position with respect to the wall, a gap is created between the back part and the wall.

As described above, in the case of using the branch fitting, since positioning and setting of the posture with respect to the wall cannot be sufficiently performed, not only is it troublesome in construction, but there is a problem of defective piping.

The problem to be solved in the present invention is to facilitate the positioning of the branch fitting and the position adjustment with the existing piping when installing the faucet on the existing piping through the branch fitting. ..

[0008]

[Means for Solving the Problems]

 The present invention is a connecting seat for connecting one end side of a branch fitting to a leg pipe that connects between a supply pipe and a faucet body provided on a wall of a building, and connecting the faucet to the other end of the branch fitting. Is a structure for mounting a faucet for fixing the connecting seat to the wall, the adjuster pin penetrating from the front side to the connecting seat, projecting in the wall direction, and adjusting the projecting amount from the front side. And a screw that penetrates the connecting seat from the front surface thereof and is screwed into the wall.

[0009]

[Action]

 If you adjust the adjuster pin on the connecting seat, the amount of protrusion of the adjuster pin from the back of the connecting seat will change, and by pushing the tip of the adjuster pin against the wall, the distance between the wall and the back of the connecting seat will be changed. Can be changed. Therefore, it is possible to adjust and set the posture of the branch fitting with respect to the supply pipe and the wall. In addition, when the tip of the adjuster pin is pressed against the wall, the branch metal fitting is temporarily fixed to the wall. Therefore, the connection seat can be positioned with respect to the supply pipe before being fixed with the screw.

In the drawing, leg pipes 2 and 3 for water and hot water are respectively connected to the back of the body 1 of the hot and cold water mixing tap, and these leg pipes 2 and 3 are connected to a water supply pipe 61 in a wall 60. Also, it is connected to a hot water supply pipe (not shown) by screw connection. A water purifier 4 is arranged on the right side of the main body 1, and a flow path between the water supply leg pipe 2 of the main body 1 and the water purifier 4 is connected by a branch fitting 5.

FIG. 3 is a cross-sectional view showing a connecting portion between the leg pipe 2 and the branch fitting 5.

The leg pipe 2 has been conventionally used for a general wall-mounted hot and cold water mixing tap, and is connected to a flow pipe by screwing it into a water supply pipe 61 piped in the wall 60, The main body 1 of the hot and cold water mixing stopper is provided with an outflow pipe 2b, the tip of which is communicated with the main body 1, an attachment port 2c for the water shutoff plug, and a water shutoff valve seat 2d provided at the front end of the flow channel cylinder 2a. When using only the hot and cold water mixing tap alone, the water shutoff tap is fixed by screwing it into the female screw 2c-1 of the mounting port 2c as in the conventional hot and cold water mixing tap.

The branch fitting 5 is fixed by screwing it into the mounting opening 2c as an alternative to removing only the water stopcock provided in the single body of the hot and cold water mixing tap. The branch fitting 5 connects the flow path from the leg pipe 2 to the water purifier 4, and is provided with a common water stop plug for the main body 1 side and the water purifier 4 side of the hot and cold water mixing tap.

The branch fitting 5 includes a main pipe 6 for connecting a flow path, and one end thereof is connected to the leg pipe 2 by a bushing 7. The bushing 7 is a hollow cylindrical body that is fixed by being screwed into the female screw 2c-1 of the mounting port 2c as an alternative to the bushing for mounting the water stop plug provided on the existing leg pipe 2. A plurality of holes 7a are opened. Then, one end of the main pipe 6 is rotatably fitted around the bushing 7, and a packing 6a is incorporated in the sliding contact surface. With such a structure, the main pipe 6 can be rotated about the fixed leg pipe 2 about the pivot point of the bushing 7, and the position of the tip can be freely changed.

At the front end of the bushing 7, a water stopper mounting seat 8 is fixed coaxially with the bushing 7 by screwing. A spindle 9 is rotatably installed in the mounting seat 8 so that a tool-hanging groove 9a at the front end faces the front surface, and a packing 9b provided at the tip can be brought into contact with and separated from the water shutoff valve seat 2d. Further, a cover 10 is integrated with the mounting seat 8 by screwing so that a driver can be inserted from the operation port 10a opened on the front surface and the tip thereof can be hooked in the groove 9a.

FIG. 4 is a cross-sectional view of a main part on the tip side of the main pipe 6 showing a structure for fixing to the wall 60 and a connection with the water purifier 4, and FIG. 5 is a front view of the tip part of the main pipe 6. ..

A sleeve 11 having a circular cross section is formed on the back of the tip of the main pipe 6 so as to project rearward, and screws 12 that are screwed into the wall 60 at two upper and lower positions to fix the main pipe 6 are inserted through the sleeve 11. There is. Further, an adjuster pin 13 for adjusting the position and posture of the main pipe 6 with respect to the wall 60 is rotatably incorporated into the sleeve 11 by screwing. The adjuster pin 13 has a groove 13a for hanging a tool on its front surface, and a shock absorber 13b made of rubber or the like that abuts against the wall 60 surface is attached to the tip. Then, a cover 11a is rotatably attached to the rear end of the sleeve 11 by screw connection, and after adjusting the position by the adjuster pin 13, the cover 11a is moved back and forth to eliminate a gap between the cover 11a and the wall 60.

A connecting seat 14 for connecting the water purifier 4 is provided coaxially with the sleeve 11 on the front surface of the tip of the main pipe 6. The connecting seat 14 has a cylindrical shape with a circular cross section having an open front end, and is formed by recessing it in the inner side as illustrated. Then, a connection port 14a communicating with the internal flow path of the main pipe 6 is opened in the center of the connecting seat 14, and the connection pipe 4a protruding to the back surface of the water purification device 4 is screwed into the connection port 14a to fix the water purification device 4. The water purifier 4 has a replaceable filter housed therein, and as shown in FIG. 2, has a structure including a handle 4b for opening and closing a flow path and a water discharge pipe 4c.

Here, 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, the bushing for attaching the 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 in which the attachment port 2c is open to the front. On the other hand, the bushing 7 is inserted into the proximal 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 and assembled. Then, of this assembly, the bushing 7 is screwed into and fixed to the female screw 2c-1 of the mounting port 2c. In this fixing work, 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 a groove 9a of the spindle 9 is screwed with a screwdriver to rotate the cover 9 to adjust the valve opening between the packing 9b and the water stop valve seat 2d.

Next, the screw 12 provided on the sleeve 11 on the tip side of the main pipe 6 is fixed to the wall 60. Before this fixing, the position of the water purifier 4 is set. That is, since the base end portion of the main pipe 6 is rotatable around the bushing 7, the posture can be changed around the bushing 7 as shown by the 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 between the main body 1 of the hot and cold water mixing tap, the sink, etc. is appropriate.

After such position setting is completed, the amount of protrusion of the main pipe 6 to the front side with respect to the wall 60 is adjusted by the adjuster pin 13 so as to match with the main body 1 side of the hot and cold water mixing valve. This is a way to adjust the distance from the wall 60 so that the driver can hang it in the groove 13a of the adjuster pin 13 and rotate it so that there is no distortion between the main pipe 6 and the connection with the leg pipe 2. To do. Then, 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 stabilized on the wall 60 together with the leg pipe 2. Fixed. Then, the cover 11a is rotated so that the back surface of the cover 11a is abutted against the wall 60.

In this way, the attitude of the branch fitting 5 with respect to the wall 60 can be adjusted by simply rotating the adjuster pin 13 from the front of the branch fitting 5 with a driver. Therefore, the position of the branch fitting 5 can be adjusted according to the distance between the wall 60 and the connection point between the base end of the main pipe 6 and the leg pipe 2, and the placement can be easily set parallel to the wall 60. it can. Therefore, no unreasonable force is applied to the joint portion with the leg pipe 2 or uneven contact is prevented, water leakage is prevented after the construction, and the branch fitting 5 is stably fixed also to the wall 60. be able to.

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 the correct posture as shown in FIG. As a result, the main pipe 6 can be used as a joint to connect the flow path on the downstream side of the water shutoff valve seat 2d in the leg pipe 2 to the water purifier 4.

As described above, in such 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. Including the case of this position change, the posture of the branch fitting 5 and the temporary fixing can be easily performed by using the adjuster pin 13. That is, when the main pipe 6 is connected to the leg pipe 2 side and then the overall attitude of the branching tool 5 is determined, if the adjuster pin 13 is moved to the wall 60 side and the buffer 13b at its tip is abutted against the wall 60, The branch fitting 5 is constrained to the wall 60 side by the pressing force between the buffer body 13b and the wall 60. Therefore, if the position of the branch fitting 5 is provisionally determined by the adjuster pin 13 and then the screw 12 is screwed into the wall 60, the work can be performed with one hand and the construction becomes easy. 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 up or down, which enables highly accurate construction.

Furthermore, if the position of the branch fitting 5 is determined by the adjuster pin 13, the screw 12 will not proceed to the wall 60 side even if it is strongly screwed. Therefore, a large load is not applied to the tip side of the branching tool 5, and there is no fear of damage.

In the embodiment, the leg pipe of the hot and cold water mixing tap is used as an example of the supply pipe on the building side. However, for example, the branch pipe may be connected to the supply pipe for the single faucet protruding from the wall. It is possible.

[0029]

[Effect of the device]

 In the present invention, by adjusting the adjuster pin provided on the connecting seat, the posture and positioning of the faucet can be easily performed with respect to the existing pipe and wall on the building side. For this reason, water leakage can be prevented without causing distortion in the connection with the existing pipe, and the back of the branch fitting can be applied to the wall exactly. 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 performed easily.
