By the way, the spout of the faucet, and further the spout of the spout for the faucet, if the height of the spout is too high from the water receiving surface of the sink, water splashes and the usability deteriorates, Generally, the height position of the spout is set low.

For this reason, there is no problem when water is supplied to shallow balls or pots, but it becomes impossible to supply water to tall containers such as pots, and once water is stored in a medicine can and stored in the back. It was unavoidable to supply water to a tall container, or to connect a rubber hose to the spout of the faucet to supply water to a tall container.

In addition, when washing a bulky item, there is a disadvantage that the item must be rotated to partially wash it.

It is an object of the present invention to provide a faucet spout pipe that solves the above-mentioned inconvenience by a simple improvement technique.

[Means for Solving the Problems]

The water discharge pipe for a faucet of the present invention comprises a joint body rotatably connected to a water spout of the faucet about a vertical axis, and a connecting member communicatably connected to the joint body about a horizontal horizontal axis. And a water conduit projecting in a direction orthogonal to the rotation axis of the connecting member, the end of which is communicated with the connecting member to swing vertically, and the water discharge part at the tip of the water conduit around a horizontal horizontal axis. A water discharge member rotatably and communicatively connected, and fixed to the connecting member in opposition to the joint body, and provided with a notch portion long in the rotating direction on a rotation restricting plate that rotates together with the connecting member. , A rotation regulating pin which is inserted into the cutout portion and regulates the rotation of the rotation regulating plate is fixedly projected to the joint body, and a plurality of small members formed on the rotation regulating plate at intervals in the rotation direction. The hole is provided within the rotatable angle of the rotation restricting plate, Wherein the one sphere ends are inserted and locked into the small hole is provided in the joint body is biased by a spring in the direction of the rotation restricting plate.

[Action]

The faucet spout pipe of the present invention connects the joint body to the spout of the faucet. In this state, when the water conduit is horizontally swung around the water discharge port of the faucet, the joint body rotates with respect to the water discharge port of the water faucet, and It is possible to discharge the water by arbitrarily selecting the position in the horizontal direction. When swinging the water conduit in the vertical direction, the connecting member should rotate within the range of the angle corresponding to the length of the notch provided in the rotation restricting plate with respect to the joint body attached to the spout of the faucet. The movable range of the vertical direction of the water conduit is
The notch and the rotation restriction pin are preset. Therefore, it is possible to prevent the water discharge member provided at the tip of the water guide pipe from moving upward or downward more than necessary to prevent water from being discharged in an unexpected direction or hitting the tableware or the like placed under the water discharge member. To do.

Further, a part of the sphere provided in the joint body is inserted into any of a plurality of small holes provided at intervals in the rotation restricting plate,
Moreover, since the spherical body is biased by the spring toward the rotation restricting plate, the small hole and the spherical body engaged with the small hole also restrict the rotation of the connecting member. For this reason, the small holes and the spheres stop the water guiding pipe in stages within the range where the water guiding pipe can swivel in the vertical direction. In the vertical swing of the water conduit, when it is slightly strongly rotated, the rotation restricting plate compresses the spring and moves the sphere toward the joint body, so that the connecting member can be rotated, When the small hole coincides with, the connecting member is stopped again.

〔Example〕

An embodiment of the water discharge pipe for a faucet of the present invention will be described with reference to the drawings.

In the figure, 1 is a faucet, which is provided with a water discharge port 4 for discharging water downward. Reference numeral 2 denotes a water faucet pipe for a faucet, which pivots a water pipe body 5 on a joint body 3 having a pipe-shaped connecting portion projectingly connected to a water spout 4 so as to be rotatable around a vertical axis P _1. Connectable and configured.

The water discharge pipe main body 5 is connected to the water flow path formed by bending the joint main body 3 into an L-shape, and is connected with a connection fitting 6 as a connection member so as to be rotatable around a horizontal horizontal axis P _2. A tubular connecting member 8 having an end portion of a water guide tube 7 fixed to the connecting fitting 6 by soldering in a direction orthogonal to the horizontal horizontal axis P ₂ and provided with a connecting hole in a part of a peripheral wall, The connecting hole is made to communicate with the water guiding pipe 7 and is fixed to the tip of the water guiding pipe 7 with solder.

The connection fitting 6 is connected to the joint body 3 by rotatably inserting the shaft body 9 protruding from the connection fitting 6 into the connection hole of the joint body 3 and by stacking the lid plate 10 on the end surface of the shaft body 9. Central hole c
The retaining screw d inserted into the shaft body 9 is screwed into the screw hole a formed in the shaft body 9 to fix the cover plate 10 to the shaft body 9 so that the connection fitting 6 and the joint body 3 are rotatable and inseparable. It is connected. Reference numeral b denotes a ring-shaped sealing material arranged on the peripheral surface of the shaft body 9.

Reference numeral 11 denotes a hollow water discharging metal fitting as a water discharging member, the cylindrical portion of the end portion of which is inserted into the connecting member 8 and the locking flange protruding from the end is locked to the end portion of the connecting member 8. , Is attached to the connecting member 8 so as to be rotatable around the horizontal horizontal axis P ₃ . A water passage communicating with the water guide pipe 7 is formed in the water discharge fitting 11. g is a spout fitting close to the end of the connecting member 8.
A retaining split ring that is locked to the outer peripheral surface of 11 is a locking groove formed on the outer peripheral surface of the water discharge fitting 11 that is in contact with the inner peripheral surface of the connecting member 8 and has a ring shape. The contact surface between the connecting member 8 and the water discharge fitting 11 is sealed with water by fitting the sealing material f. Reference numeral 12 is a foamer attached to a water discharge hole provided at the end of the water discharge fitting 11, in which a mesh body h is arranged.

According to the above configuration, by rotating the faucet water discharge pipe 2 around the vertical axis P _{1 with} respect to the water discharge port 4 of the water faucet 1, the water discharge fitting 11 and thus the foamer 12 are shaken in the left-right direction. Since the joint body 3 and the water discharge fitting 11 are rotatable around the horizontal horizontal axes P ₂ and P ₃ with respect to the water discharge pipe main body 5, the water discharge fitting 11 and the foamer 12 are held. By vertically moving it in parallel, the water discharge height position of the foamer 12 with respect to the water receiving surface of the sink can be changed.
That is, the height position of the foamer 12 can be changed up and down according to the height of the container to be water-supplied, the size of the bulk of the washing, and the like.

Next, 13 in the drawing is a rotation restricting means for restricting the rotation angle range of the discharge pipe main body 5 with respect to the joint main body 3 around the horizontal vertical axis P ₂ , and as shown in FIG.

The main body 5 is rotatable from a horizontal position over an angle range in which the main body 5 is lifted upward.

That is, it is possible to avoid the inconvenience of accidentally breaking the tableware by unnecessarily lowering the water discharge pipe main body 5 provided with the foamer 12.

Reference numeral 18 denotes an urging fixing means for urging and fixing the water discharge pipe main body 5 at a plurality of upper and lower positions within a rotation restricting range of the rotation restricting means 13, which is provided in the cutout portion 17 with respect to the rotation restricting plate 15. Within the corresponding angular range, a plurality of small holes 19 are formed at predetermined intervals in the circumferential direction, while a sphere body 21 is partly biased into the small holes 19 by the biasing force of a spring 20 so that the joint body The water discharge pipe main body 5, which is provided on the third side and is connected to the water discharge metal fitting 11, is urged and fixed at a total of three positions of a horizontal position and two positions above it against the gravity.

In addition, as shown in FIG. 3, the stopper screw d is unscrewed to remove the lid plate 10 and the rotation restricting plate 15, and the joint body 3 is rotated 180 degrees with respect to the water discharge pipe body 5. Further, the rotation regulating plate 15 is also rotated 180 degrees and set again to form the faucet spout pipe 2 used for the upward spout type faucet 1, as shown in FIGS. 5 and 6. Can be changed.

Alternatively, as shown in FIG. 7 and FIG. 8, the cutout portion 16 of the rotation restricting means 13 and the small hole 19 of the biasing fixing means 18 are provided with a phase angle of 180 degrees with respect to the rotation restricting plate 15. If it is formed by holding it, the joint main body 3 is rotated 180 degrees with respect to the water discharge pipe main body 5 in a state in which the pin 17 of the rotation restricting means 13 is removed, and then the pin 17 is only reset. Then, the faucet spout pipe 2 for the faucet 1 for the downward spouting type
Can be changed to a faucet spout pipe 2 for the upward spout type faucet 1.

However, in the water discharge pipe 2 for faucet obtained by these configuration changes, the bias direction of the water discharge pipe body 5 with respect to the joint body 3 is constant, and the bias direction of the water discharge pipe body 5 is reversed left and right. If you can, simply sprinkle metal 11
By reversing the direction of 180 degrees, the configuration can be changed to the faucet spout pipe 2 for the upward spout type faucet 1.

Further, in the embodiment, the water discharge pipe main body 5 is prevented from rotating downward from the horizontal posture, but the present invention is not limited to this, and the water discharge pipe main body 5 is also rotatable downward from the horizontal posture. It goes without saying that it can be carried out.

[Effect of device]

As described above, the faucet water discharge pipe of the present invention connects the joint body to the water discharge port of the faucet so that the water conduit can be horizontally moved by rotating the joint body with respect to the water discharge port. It can be swung, and the horizontal position of the water discharge member provided at the tip thereof can be selected almost arbitrarily. Further, since the water conduit can be swung in the vertical direction by the rotation of the connecting member that is rotatably connected to the joint body, the vertical position of the water discharge member can be selected almost arbitrarily. It is possible. So, for example,
Since the water discharge member can be placed at a position corresponding to the size or shape of the object to be washed and water can be discharged therefrom, it is possible to wash the entire object to be washed easily and evenly.

Moreover, the movable range of the connecting member in the up-down direction is restricted by the notch and the rotation restricting pin to prevent the water conduit from swinging in the up-down direction more than necessary. The plurality of small holes provided on the motion restricting plate and the sphere provided on the joint body by the spring urging toward the rotation restricting plate enable the connecting member to be stopped stepwise. Therefore, it is possible to prevent the water discharge member at the tip of the water guide pipe from moving upward or downward more than necessary, and to prevent water from being discharged in an unexpected direction or the water discharge member from hitting dishes or the like below it. It is possible to perform the swing operation in the up-and-down direction at ease. Since the water conduit can be stopped stepwise in the vertical direction, it is possible to more stably discharge the water from the water discharge member and use it.
