[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint attached to a pipe, and more particularly to a joint for attaching a water-saving piece in a water supply channel.

[0002]

2. Description of the Related Art Conventionally, in the use of water supply equipment provided with a flow control opening / closing faucet such as a faucet, a faucet is often opened more than necessary and water is wasted. Then, water saving top A to prevent wasteful release of water was developed,
As shown in FIG. 8 and FIG. 9, it is attached to the inside of the faucet member C or to a connecting portion of a pipe connected by a connecting fitting D such as a cap nut, thereby exhibiting a water saving effect.

[0003]

However, the mounting position of the water-saving top A is limited to the inside of the faucet member C of the water supply or the connecting portion by the connecting fitting D, and is provided at an arbitrary position in the middle of the pipe. There is a defect that it cannot be installed.

The present invention has been proposed in view of the above problems, and an object of the present invention is to provide a joint that can easily attach a water-saving piece to an arbitrary position in a pipe.

[0005]

In order to achieve the above object, a joint according to the present invention is a joint attached to a pipe, which is formed in a hollow cylindrical body, and has at least one end in the axial direction. And a connecting screw part connectable to a screw part formed at an end of the pipe, and a storage means for storing a water-saving piece therein is provided. Also,
The storage means may include a support portion that receives the flange portion of the water-saving coma having a flange portion formed at one end in the axial direction, and a storage portion that stores the water-saving coma body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the joint according to the present invention will be described below in detail.

The joint 1 of the present embodiment is made of stainless steel, and is attached to a connecting portion of a pipe connected by a screw mechanism. Basically, as shown in FIG. 1, it is formed in a hollow cylindrical body, and has a female screw portion 5 at one axial end and a male screw portion 6 at the other axial end.
A storage mechanism 8 is provided as storage means for storing a packing 7 and a water-saving top A described later.

The storage mechanism 8 includes an annular packing mounting portion 81 on which the packing 7 is mounted, and a flange portion A of the water-saving top A.
Annular flange support portion 8 as a support portion for supporting 2
2 and 84, and a main body storage portion 83 as a storage portion capable of storing the main body portion A3 of the water-saving top A. The packing mounting portion 81 is provided below the female screw portion 5 along the inner peripheral surface, and the flange support portion 82 is provided with the packing mounting portion 81.
And has a smaller diameter than the packing mounting portion 81. Below the flange support portion 82,
A main body storage portion 83 formed in a cylindrical shape is provided. On the other hand, the flange support portion 82 is also provided at the end on the male screw portion 6 side.
A flange support portion 84 having the same shape as that of FIG.

Next, an example of use of the joint 1 of the present embodiment will be described. The joint 1 is attached to a faucet portion of a tap formed by screwing a rectifier 4 made of stainless steel into the opening 3 at the distal end, for example, as shown in FIGS. Specifically, as shown in FIGS. 4 and 5, first, the female screw portion 5 of the joint 1 is disposed to face the distal end opening portion 3, and the water-saving top A is provided from the female screw portion 5 side.
Is inserted, and stored in a state where the flange portion A2 of the water-saving top A is supported by the flange support portion 82. After storing the water-saving frame A, the packing 7 is inserted in the same manner, and the packing 7 is mounted on the packing mounting portion 81. Next, a male screw (hereinafter referred to as a faucet-side male screw portion 31) formed in the distal end opening 3 of the faucet main body 2.
), The female thread 5 of the joint 1 is screwed together, the joint 1 is attached to the faucet main body 2, and the male screw 6 provided at the other end in the axial direction of the joint 1 is fitted with the female screw (Hereinafter referred to as rectifier-side female screw portion 41), the rectifier 4 is attached to the joint 1, and the joint 1 is attached between the faucet main body 2 and the rectifier 4.

As described above, the joint 1 of the present embodiment is
It has a storage mechanism 8 for storing the water-saving coma A inside, and at the one end in the axial direction, a female screw portion 5 attachable to the end of one of the connected pipes is formed, and at the other end in the axial direction. Since the male screw portion 6 attachable to the end of the other pipe to be connected is formed, the tip opening 3 of the water tap is provided.
Water-saving top A using the faucet-side external thread 31 formed in
Can be attached to the faucet. In addition, since the fitting work of the joint 1 can be performed by hand, no special tool or heavy work is required, and anyone can easily and easily perform the work.

The storage mechanism 8 is provided with a packing mounting portion 81.
And the flange support portions 82 and 84 that support the flange portion A2 of the water-saving top A and the main body storage portion 83 that stores the main body portion A3 of the water-saving top A. The water-saving coma A can be stored inside the joint 1 also from the side. Therefore, for example, when the faucet tip opening 3 is a female screw, the joint 1 can be turned upside down and the male screw part 6 can be screwed into the faucet tip opening 3 female screw. 1 can be connected to the faucet. The packing 7 has an end surface 11 on the other end side in the axial direction of the joint 1.
Attach to.

Further, since the packing mounting portion 81 and the flange support portion 82 are provided annularly along the inner wall surface,
Displacement of the mounted packing 7 and the water-saving top A in the left-right direction is unlikely to occur.

The fitting point of the joint 1 is not limited to the opening 3 at the tip of the faucet main body 2.
As shown in FIG. 6, it may be attached to a connection portion of pipes 9, 10 connected by a screw mechanism. Further, FIG.
As shown in FIG. 7, the pipes 11 and 12 can be attached to a portion where the pipes 11 and 12 are connected by the cap nut 13. Also,
The fitting location of the joint 1 is not limited to the connection part of the pipe, but if a part of the pipe is cut and a screw mechanism is formed at the cut part, the joint 1 can be attached to an arbitrary part of the pipe. Can be.

The material of the joint 1 is not limited to stainless steel, and may be any material having a hardness that does not crush the threads of the pipe to be connected, and may be the same as the material of the pipe to be connected. Is preferred. Therefore, for example, when the rectifier 4 is made of brass, the material of the joint 1 is also the rectifier 4
Brass may be used as in the case of the material. When the rectifier 4 is made of plastic, the joint 1 may be made of plastic.

The outer diameter of the joint 1 is preferably the same as the outer diameter of the opening 3 at the end of the faucet main body 2. In this case, when the joint 1 is attached to the faucet main body 2, Since there is no unevenness on the outer peripheral surface, the appearance is clear and dirt is hard to adhere.

[0016]

The joint of the present invention is a joint attached to a pipe, which is formed in a hollow cylindrical body and has at least one end in the axial direction and a thread formed at an end of the pipe. It has a connecting screw part that can be connected and a storage means for storing the water-saving coma inside is provided. Can be attached to the tip opening of the faucet. According to the second aspect of the present invention, since the storage means includes the support portion for receiving the flange portion of the water-saving coma having the flange portion and the storage portion for storing the water-saving coma body portion, the water-saving coma is provided.
