Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faucet in which a water discharge pipe is divided into a plurality of divided pipe portions and the divided pipe portions can be positioned at arbitrary angles in all directions.

[0002]

2. Description of the Related Art Recently, kitchen sinks of various shapes, sizes and depths have been provided. For this reason,
If a general faucet, that is, a faucet with a fixed length and height of the discharge pipe, is attached to such a kitchen sink,
Depending on the size and depth of the sink, there is a problem that the height of the water outlet at the tip of the water outlet of the faucet, that is, the height of the outlet is too high or too low. Therefore, as shown in FIG. 3, the water discharge pipe 27 is divided into a plurality of pipes, and the divided pipe portions 28a, 28
There is proposed a faucet 30 in which b and 28c can be positioned at arbitrary angles in all directions by connecting portions 29a and 29b and are connected in a communicating state so as to form a water passage.

[0003]

However, in such a faucet 30, the divided pipe portions 28a to 28c are connected to each other so that they can be positioned at arbitrary angles in all directions, and the divided pipe portions 28a to 28c are secured in order to secure a rotation region thereof. A narrow gap is formed in the connecting portions 29a and 29b between the portions. For this reason, the connecting portions 29a, 29b are easily soiled due to dirty water, dust, dust, etc., and since they are narrow areas, it is troublesome to clean them.
Further, there is also a problem that the appearance becomes bad due to the dirt.

[0004]

According to another aspect of the present invention, there is provided a faucet having a joint member in which a water discharge pipe is divided into a plurality of divided pipe portions, and adjacent divided pipe portions have a hollow water passage. In a water faucet connected through a position in which it can be positioned at any angle in all directions, an expandable cover is attached around the connecting part.

[0005]

Operation: Since the periphery of the connecting portion connecting the divided pipe portions is protected by the elastic cover, the connecting portion does not get dirty. Therefore, the appearance is good. In addition, the rotating operation of the joint member provided in the connecting portion can be stably performed.

[0006]

Embodiments of the faucet according to the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing a state in which a water tap according to the present invention is partially cut away. In FIG. 1, the water faucet 1 of this example is a single lever type water faucet provided in a kitchen sink. The faucet 1 includes a faucet body 2 and
A water discharge pipe 3 extending obliquely upward from a lower portion of the faucet body 2.
An operating lever 4 is attached to the faucet body 2. By operating the operation lever 4 to rotate in the up-down direction and rotate in the left-right direction, the discharge / stop of water or hot water, the flow rate adjustment, and the temperature adjustment can be performed.

In this example, the water discharge pipe 3 is formed in a curved shape with a first divided pipe portion 5a which is integrated with the lower portion of the faucet body 2 and a second divided pipe portion 5b which is a straight pipe. The three divided pipe portions of the third divided pipe portion 5c reaching the discharge port 6 are connected to the connecting portion 8
The a and 8b are rotatably connected to each other so that they can be positioned at arbitrary angles in all directions.

FIG. 2 is a cross-sectional view showing the structure of the connecting portion 8b. Below, for convenience, the connecting portion 8b of the second divided pipe portion 5b and the third divided pipe portion 5c will be explained, but of course the connecting portion 8a. Has a similar structure. The connecting portion 8b is the second
The divided pipe portion 5b and the third divided pipe portion 5c are connected by the ball joint member 9. The ball joint member 9 includes a shaft portion 10 and a ball portion 11, and has a hollow water passage 12 that axially communicates with the second divided pipe passage 5b and the third divided pipe passage 5c.

In the second divided pipe portion 5b, the ball portion 11 of the ball joint member 9 is the second divided pipe portion 5b.
It is slidably rotated on the inner peripheral surface of the receiving member 13 fitted in the end portion of b, and is positioned at an arbitrary angle in all directions within a range regulated by the ball portion 11 and the receiving member 13. The cap nut 14 is mounted by being screwed onto a threaded portion formed on the outer peripheral portion of the second split pipe portion 5b, and the receiving member 13 and the ball portion 11 are attached to the end of the second split pipe portion 5b. The part is closed and stored in a watertight manner.

On the other hand, in the third divided pipe portion 5c, the second
A hollow screw member 18 composed of a flange portion 16 and a shaft portion 17 is water-tightly screwed to the end portion on the side of the divided pipe portion 5b so as to contact the end surface 15. The ball joint member 9
The shaft portion 10 is attached by being screwed into a storage portion 19 formed from the flange portion 16 of the hollow screw member 18 to the central portion of the shaft portion 17.

The flange 16 of the third divided pipe portion 5c and the outer peripheral surface of the second divided pipe portion 5b are covered with a cover mounting groove 20,
21 are formed respectively. The cover 22 has a bellows-shaped (bellows-shaped) expandable and contractible hollow cover as a main body, and both peripheral end portions thereof are formed as thick-walled locking portions 23, and the locking portions 23 serve as the cover mounting groove 20, 21 is engaged and attached.

As for the material and shape of the cover 22,
Any shape may be used as long as it is stretchable, such as resin, elastomer such as rubber, cloth, or the like. In particular, it is preferable to use a colored pipe of the same system as that of the water discharge pipe 3 and to have an outer diameter similar to that of the split pipe portions 5b and 5c, because it gives a clean appearance.

The locking portion 23 may be made of the same material as the cover body, but the cover mounting grooves 20, 21
It is also possible to attach one having a higher hardness than the main body so that the engagement strength with is stronger. In order to mount the cover 22, the cover 22 is preliminarily fitted on the outer circumference of one of the divided pipe portions 5b or 5c, and after the connecting portion 8b is formed by the ball joint member 9, the cover 22 is displaced toward the connecting portion 8b. The cover mounting groove 20,
It should be attached to 21. It should be noted that, in addition to forming the cover mounting groove 20 into a circular groove shape and making the locking portion 23 ring-shaped,
Of course, the locking portion 23 may have a claw structure, and the cover mounting groove 20 may be composed of a plurality of locking holes.

Thus, in the case of the water faucet 1 of this example, the divided pipe portion 5
A gap 24 is formed between a, 5b, and 5c to form a rotation region, but the second divided pipe portion 5b and the third divided pipe portion 5c are formed with the connecting portions 8a and 8b as base points. When the ball is rotated two-dimensionally or three-dimensionally, the ball portion 11 of the ball joint member 9 provided on the connecting portions 8a and 8b rotates while guiding the inner peripheral surface of the receiving member 13. The protrusion amount (length) and height of 6 can be changed appropriately.

The expandable cover 22 is connected to the connecting portion 8.
Since a and 8b are covered, the divided pipe parts 5a, 5b and 5
Even if the c rotates to cause the gap 24 to become wider or narrower, the cover 22 expands and contracts correspondingly, so that the gap 24 is always irrespective of the rotating position of the divided pipe portion.
Will be covered.

Further, since the cover 22 covers the gap 24, the narrow groove portion 25 formed by the divided pipe portions 5a, 5b, 5c and the surface of the shaft portion 10 of the ball joint member 9 is formed.
However, it is protected from dirty water, dust, dust, etc., so it does not get dirty. Further, since the groove portion 25 is also a rotation mechanism portion, since such a dirt is not attached, it is possible to ensure a good aesthetic appearance and to secure a stable rotation operation. Further, since it is only necessary to replace or clean the cover 22, the cleaning work is easy.

Incidentally, the connecting portion 8 in the above-mentioned embodiment.
The a and 8b are not limited to the case where the ball joint member 9 described above is used, and various other forms can be used. Further, the faucet of this example can of course be applied to other than the faucet provided in the kitchen sink.

[0018]

As described above, according to the present invention, in the faucet which can be rotated to position the plurality of divided pipe portions at arbitrary angles in all directions by using the joint member, the divided pipe portions are provided. Since the gap formed in the mutual connecting portion is covered, this portion is not soiled. For this reason, since the rotation mechanism portion is protected, a stable rotation operation can be performed. In addition, it has a good appearance and is easy to clean.
