Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single lever type single faucet which uses the body of an ordinary compression type single faucet installed as a faucet of a water supply, and more specifically, a single 360 ° rotatable single horizontal tap. The present invention relates to a lever-type single faucet.

[0002]

As is well known, a single faucet has a maximum working pressure.
It is attached to the end of the water supply pipe of 7.5 kg / cm ² and is used in communication with so-called water supply, so it is necessary to conform to the standard, for example, the material of the body of a single faucet is bronze. It is considered to be a casting.

When the single faucet is structurally classified, a compression type in which a valve is opened / closed by lifting and lowering by a screw of a tap rod, a plug type in which a faucet shaft is opened / closed by rotating 90 °, and a manual type With a self-closing type in which the valve seat opens and is closed by a spring or water pressure, or a ball tap type in which the ball acts as a float in water and the valve at the tip of the ball opens and closes depending on the amount of water. It is classified.

Of these, the most commonly used one is a compression type single faucet. The compression type single faucet has a simple structure, is inexpensive, is compact, does not occupy a lot of space, and has few failures. Since the coma packing is pressed every time the valve is closed, there is a disadvantage that the life of the coma packing is short. Moreover, since the screw of the stopper rod is screwed up and down, the stopper rod is rotated by an appropriate handle or knob. It has to be done, and the operation is a little, but it is troublesome.

On the other hand, a water pipe is branched and connected to a washing machine, a water purifier or the like. For example, in a condominium (condominium made of concrete), a concrete
Since it is impossible to newly install a branch pipe in the water pipe buried in the wall of the wall, a branch plug is attached to the existing water tap, and connection is performed from this branch plug.

Therefore, the inventor of the present invention, as shown in FIG. 2, has an inlet portion 30 communicating with a water pipe and an outlet portion 3 forming a faucet.
1, a horizontal comer sheet portion 32 for partitioning the inlet portion 30 and the outlet portion 31, a cylindrical rising portion 33 extending above the comer sheet portion 32, and the rising portion 33. In a body A'of a compression type single faucet consisting of a male screw 35 provided on the outer periphery of the upper part, a leg portion 2'which abuts on the coma sheet portion 32 and is inserted from a rising portion 33 is a single lever type. The leg body 2 ′ extends downward in the plug body 1 ′ of the single faucet, and the leg 2 ′ is provided with the inflow passage 2a ′, the first outflow passage 2b ′, and the second outflow passage, respectively.
a ′ is communicated with the inlet portion 30 and the first outflow passage 2
b'communicates with the outlet portion 31, and the cap nut 3 is loosely fitted over the leg portion 2'and screwed with the male screw 35 to set the plug body 1'on the body A '. The cartridge main body 5 having a valve made of fixed and movable discs 7 and 8 made of ceramics is housed in the ', and the operating lever 13 is connected to the movable disc 8 to connect the inflow passage 2a' and the first outflow passage. Two
b ′ and the second outflow passage are opened and closed, and a ring-shaped branch hub 15 ′ having a pipe joint 19 ′ on the side is rotatably fitted to the lower side of the plug body 1, and the pipe joint is 19 '
Has proposed a single lever type single faucet having a branching port characterized by communicating with the second outflow passage (utility model registration No. 2091439).

In FIG. 2, 6'is a screw, 17 'is a strip-shaped water passage groove, 20' is a branch port, and 21 'is a plug.

Therefore, if this compression type single faucet is changed to a single lever type single faucet having such a branching port 20 ', the branching port 20' with respect to the plug body 1'is
It can be horizontally rotated 360 ° and positioned in any direction, and even if the faucet of the body A'is fixed, it can be connected to a water purifier or the like at any position without interfering with each other. .

[0009]

However, in the single lever type single faucet having such a branch port 20 ', although the valve opening / closing operation is easier than the operation of the compression type single faucet, the compression type single water faucet is operated. Since the stopper is particularly low in length and the entire body is made compact, the compression type single faucet installed in a place with a small space is replaced with a new single lever type. There were complaints that it was difficult to change to a single faucet.

Therefore, in the present invention, in the single lever type single faucet having such a branch port 20 ', the height is made as low as possible, and the operation lever 13 which is conventionally fixed in a fixed direction is horizontally moved. It is possible to rotate 360 °, and by arranging in any direction, it is possible to change the dead space by utilizing the dead space.

[0011]

Therefore, the present invention provides 1)

By doing so, a single lever type single faucet that opens and closes the valve is configured.

Therefore, according to this single lever type single faucet, the joint body 1, the leg portion 2 and the cap nut 3 are integrally fixed to the body A ', and the cartridge body 5 and the receiving tray 6 are provided. The operating lever 13 and the operating lever 13 are integrated to form the joint body 1
Since it is rotatably supported by the side, this operation lever 13 can be rotated 360 ° horizontally and positioned in any direction.

In particular, the joint body 1 to which the leg portion 2 and the cap nut 3 are attached is inserted from below the cartridge body 5 having no bottom and rotatably incorporated therein so that the bottom portion of the cartridge body 5 is secured. Since it is rotatably supported by the dual-purpose tray 6, it does not have a vertical height because it is dish-shaped, and therefore, the height of this single faucet can be made as low as possible, and the operation lever 13 is used. In the horizontal 360 ° rough rotation, not only the cap nut 3 but also the leg portion 2 is not added, and moreover, the joint body 1 having a larger diameter than the leg portion 2a.
And rotatably support the cartridge body 5 and the saucer 6,
Since the momentum and the supporting surface pressure are reduced, horizontal 360 ° rotation can be performed lighter.

The valve is opened and closed by swinging the operating lever 13 up and down, which is the same as a normal disc valve operation.

Next, the single lever type single faucet will be described in detail by dividing it into "joint body 1", "leg portion 2", "cartridge body 5" and "sauce tray 6".

The "joint body 1" is made of copper alloy (made of metal) and is a member that rotatably connects the leg portion 2 and the cartridge main body 5, and is provided on the leg portion 2 in a flange shape. The upper and lower inner and outer ring portions 1A and 1B are integrally formed by cutting in a stepped manner from the upper inner ring portion 1A and the lower outer ring portion 1B.
A plurality of arc-shaped outlets 26 are opened at the boundary between A and 1B.

Therefore, even if the operation lever 13 is rotated 360 ° horizontally by the outlet 26,
Even if the outlet 26A of the fixed disk 7 is located at any horizontal position of 360 °, the outlets 26 and 26A can communicate with each other.

In this upper inner ring portion 1A, the upper end of the SUS pipe 20 forming the center side of the leg 2 is attached to the O-ring 16A.
