Description

[Detailed description of the invention] [Industrial field of application] The invention is applicable to a water faucet that is installed as a water faucet.
This is a so-called cylinder stem type single faucet that uses the body of a normal compression type single faucet as specified by JIS.

[Conventional technology and its problems]

This type of compression type single faucet, which is standardized by JIS and is used in general households, has an extremely simple structure, can be provided at low cost, and has the advantage of being less likely to break down. Therefore, it is most widely used, but on the other hand, the service life of the stopper is short because the stopper is pressed every time the stopper is closed, and in order to screw the screw of the stopper rod back and forth, it is difficult to use the stopper rod with an appropriate handle or knob. It also has the disadvantage that it has to be rotated, and the operation is somewhat troublesome.

Therefore, the inventors of the present invention tried to solve the drawbacks of the compression type single faucet, and as a result of trial and error, for example, Publication of Utility Model Publication No. 56-26134, Publication of Japanese Utility Model Publication No. 56-30785, Publication of Japanese Patent Publication No. 59-10446, etc. As shown in the above publication, a so-called cylinder stem type (particularly defined in this specification) using a single lever, which is well-known for hot and cold water mixing faucets, is a cylinder with a lower notch opening. They came up with the idea of applying the structure of a water faucet (also referred to as a faucet that opens and closes by sliding a piston in a pipe) to a single faucet.
However, the single-lever type hot water mixer faucet, which has a cylinder stem type structure, has a complicated structure and costs significantly higher than the general so-called compression type single faucet. However, they still faced a new problem: high costs.

Therefore, we used the body of the conventional compression type single faucet, which is restricted by JIS standards, without making any changes, and added the above-mentioned single lever type cylinder stem type member to this body. The present applicant solved the above-mentioned problem by simplifying the structure so that it can be attached to and detached from the body very easily. ).

This is shown in FIG. 2, but before that, the body A of the well-known compression type single faucet standardized by JIS will be explained. In FIG. 3, this body A has an inlet portion 3 connected to a water pipe (not shown).
0, an outlet part 31 forming a faucet, a horizontal top sheet part 32 that separates the inlet part 30 and the outlet part 31, a cylindrical rising part 33 extending above the top sheet part 32, and a top 34. A stopper rod threaded portion 35 is carved on the inner periphery of the cylindrical rising portion 33 to screw a stopper rod (not shown) removably attached to the tip thereof; It is composed of a packing retaining screw 36 carved on the outer periphery of the inlet portion 30, an abutment flange 37 provided on the outer periphery of the inlet portion 30, and a joint screw 38.

The main part of a single faucet B (this is called a cartridge and is constructed as a set and is difficult to disassemble) attached to the body A of such a structure is constructed as follows. In FIG. 2, a cylindrical rising portion 33 is placed on the horizontal top sheet portion 32 of the body A.
The cylinder 1 having a slightly smaller diameter than the threaded part 35 for screwing the stopper rod is inserted into the upper opening and placed thereon. This cylinder 1 has a portion 33 rising from the upper surface of the top sheet portion 32 at a portion approximately equal in length to the opening end, and a flange 2 is provided around the outer periphery of the portion 33 . A cap nut 3 (corresponding to the gasket holder of a conventional single faucet) is screwed onto the gasket holder screw 36 with the flange 2 in between. This cylinder 1
A screw is carved on the outer periphery above the flange 2 of the
Screw on the fixing nut 4.

A lever fulcrum case 6 having a locking portion 5 is loosely fitted into the first fixing nut 4 . This locking part 5
The second insert fixing nut 7 is screwed onto the upper outer circumferential screw of the cylinder 1 with the second insert fixing nut 7 in between. Therefore,
When the cap nut 3 is screwed onto the gasket retaining screw 36 of the cylinder A through the attachment gasket 8, the cylinder 1 is fixed in a state in which it is placed on the piece seat portion 32.

A tubular piston 9 corresponding to the stem is loosely fitted into the cylinder 1 so as to be able to slide up and down, and a pair of openings 1 are cut out below the middle of the cylinder 1.
O-rings 11 and 11 are provided with O-rings 11 and 10 being inside, and the tubular piston 9 is loosely fitted through the O-rings 11. A fulcrum metal fitting 12 is fixed to the upper and lower middle of this tubular piston 9, and one lever C is fixed to this fulcrum metal fitting 12 so as to be able to swing vertically about the fulcrum lever case 6 as a fulcrum.

A screw is carved into the upper outer periphery of the fulcrum lever case 6, and the balance case 13 is fitted and placed therein. The holding nut 14 screwed onto the balance case 13 is screwed onto the screw of the fulcrum lever case 6. This balance case 13 has a tubular piston 9
The tip of is intruding.

Note that a cosmetic cap 15 is removably fitted onto the balance case 13.

By the way, in such a single faucet, as shown in FIG.
If the height from the bottom end of cylinder 1 to flange 2 in single faucet main part (cartridge) B is different, adjust the thickness of mounting gasket 8 to absorb this height discrepancy. ing. However, with such thickness adjustment, if the already installed shell A is used as is, there is a limit to the thickness since the mounting gasket 8 is intended for water sealing, and it is particularly difficult to install on site. It takes a while,
As a result, reliability against water leakage will be impaired. Therefore, it is possible to prepare multiple cylinders 1 with different lengths and visit the site, but in the case shown in the second figure, this cylinder 1 is integrated into a so-called cartridge.
extends upward, and this cylinder 1 is integrated with the fulcrum lever case 6 through the first fixing nut 4 and the second insert fixing nut 7 screwed downward, so that it can be disassembled. is not ready. In particular, the second insert fixing nut 7 requires a special tool and is difficult to disassemble.
There was an unresolved problem.

is divided into a cylindrical socket 1a that abuts the piece seat portion 32 and is provided with a lower notch opening 10 of the cylinder 1, and a flanged cylinder 1B that abuts the upper opening end of the cylindrical rising portion 33. In addition, the thread on the upper outer periphery of the cylindrical socket 1a can be screwed onto the thread on the lower inner periphery of the flanged cylinder 1b, making it possible to replace it with another cylindrical socket having a different shaft length. There is a single faucet.

〔Example〕

The structure and operation of the present invention will be explained in detail with reference to embodiments shown in the accompanying drawings. Note that the same parts or equivalent parts as shown in FIG. 2 are given the same reference numerals, and the explanation thereof will be omitted.

In Fig. 1, 1a is a cylindrical socket, 1b is a cylinder with a flange, and this cylindrical socket 1a
A screw is carved on the upper outer periphery, and a screw is carved on the lower inner periphery of the flanged cylinder 1b, and both screws are screwed together to form the cylinder 1.

The lower body case 4a is screwed onto the upper body case 6a, and an operating lever C is inserted between them so as to be movable up and down in a specific direction. Therefore, unlike the one in FIG. 2, the operating lever C cannot freely rotate on a plane. The base of this operating lever C is the fulcrum metal fitting 12 of the tubular piston 9 (corresponding to the stem).
It is locked to. A screw 16 is formed on the upper inner periphery of the upper main body case 6a, and a screw engraved on the outer periphery of the balance case 13 is screwed into this screw 16. A branching joint 17 is rotatably fitted into the upper outer periphery of the upper body case 6a, and a plurality of communication holes 18 are bored therein. That is, a portion of this branching joint 17 is loosely fitted into an upper portion of the upper body case 6a, and the remaining portion is loosely fitted into the holding nut 14. This holding nut 14 is screwed onto the upper body case 6a side and is interposed between the branching joint 17 and the upper body case 6a. In addition, 19 is a screw that integrates the cosmetic cap 15 and the balance case 13, 23 is a seal ring screwed into the balance case 13, 20 is an O ring, which opens and closes the small hole 22 communicating with the pressure chamber 21.

1 and releases water. Further, when the operating lever C is pushed down, the tubular piston 9 slides downward, and the lower notch opening 10 is closed by the tubular piston 9.

In addition, when using the branching joint 17, connect this joint 17 to a dishwasher, water purifier, etc., and rotate the cosmetic cap 15 about 1 to 1.5 times to raise the balance case 13 with the screw 16. , the tubular piston 9 and the communication hole 18 communicate with each other,
Water is sent to predetermined equipment from the branching joint 17.

[Effect of idea]

According to this invention, the main part of a so-called cylinder stem type single faucet is attached by using the body of a normal compression type single faucet standardized by JIS that is installed as a water faucet. Therefore, it is possible to use inexpensive bodies that are commercially available and already installed on walls, etc., which reduces the overall cost of the single faucet. Work is being done to replace the presser foot, stopper bar, and top, but
Since the main part of a cylinder stem type single faucet (cartridge) can be installed in the same way as this, the installation work can be made extremely easy. Moreover, since it is a cylinder stem type single faucet, there is no need to press the seal like in a compression type single faucet, and the life of the O-ring can be extended. In addition, since the tubular piston is moved up and down, it is much simpler than the operation of turning the stopper rod of a normal compression type faucet. In particular, the flange of the cylinder is sandwiched by a cap nut that is screwed in using a screw for holding the seal, and it is fixed to the cylindrical rising part, so even an amateur can easily attach the cylinder to the body without using any special fixing tools. Can be fixed. Furthermore, since the flange and the lower end of the cylinder are in contact with the body and screwed together with cap nuts, installation is easy. It will not come off during use.

In addition to this special effect, the following effects are also achieved.

The cylinder 1 constituting the main part of the single faucet called the cartridge is inserted into the lower notch opening 1.
Since the cylindrical socket 1a having 0 and the flanged cylinder 1a having the flange 2 are integrated so that they can be screwed on and removed, the cylindrical rising portion 33 on the body A of the compression type single faucet to be installed Even if the height X of the cylinder A is different (depending on the residence, the height ,
The height X can be adjusted by easily replacing only the downwardly projecting cylindrical socket 1a of the cylinder 1. Therefore, it is convenient for ad hoc on-site construction.
