Description

  The present invention relates to a pipe provided with a connection mechanism used for drainage piping etc. More specifically, in a pipe provided with a connection mechanism for performing a simple connection, the connection mechanism in which the degree of freedom in piping layout is enhanced It relates to the provided tube body.

2. Description of the Related Art Conventionally, in equipment such as sinks, washbasins, bathtubs and the like that generate drainage due to use (hereinafter referred to as "drainage equipment"), drainage pipes for treating the drainage of drainage equipment are It is widely known.
The drainage piping of these drainage equipments connects the end of the pipe body with a pipe body of various shapes such as a straight pipe, a bent pipe, or a pipe body called a trap pipe in which the pipe body is bent in a U shape. Is done.
Usually, adhesion using an adhesive or screw connection using a packing and a nut member is often used to connect the ends of the tube, but the following problems are encountered with these methods. was there.

When connecting pipes by adhesive bonding, the applied adhesive hardens, and it takes a considerable amount of time to complete the bonding, and it may be necessary to interrupt the work each time bonding is performed. The
In addition, since stress is generated in the connected pipe due to the weight of the pipe itself and the elasticity of the connected pipe, etc., the adhesive hardens in the pipe so that the bonding position does not shift due to these stresses. Until the bonding is completed, it may be necessary to fix the tube with a fixing stand or the like and to remove the fixing stand after the adhesive is cured.
In addition, it is necessary to make a watertight and reliable connection so that there is no leakage of gas or liquid flowing inside, especially liquid such as drainage, but this kind of reliable connection can be achieved by adhesion. In order to do it, the skill and skill of the builder are required, and there was a problem that watertight connection was difficult.
In addition, when the adhesive hardens, it is not possible to release the connection of the pipe body or move the connection angle / position again, so fine adjustment of piping after construction, damage to piping members etc. and replacement of members etc. Was difficult, there was a problem.

Therefore, there has been proposed a drainage pipe which enables simple and reliable watertight connection of the pipe body as described in Patent Document 1 and also enables separation of piping members and fine position adjustment even after construction.
The pipe body provided with the connection mechanism described in Patent Document 1 is composed of a drainage main body, a drainage joint, a trap pipe, and a J-shaped pipe described below, and is applied to a wash bowl described below.
Note that the upper and lower sides in the following description are based on the upper and lower sides of the drawing in Patent Document 1.
The wash bowl is a box that is open at the top, and the bottom surface thereof is provided with a mounting hole through which the drainage main body is inserted.
The drainage port main body has a substantially cylindrical shape, and is provided with a collar portion protruding in the outer peripheral direction at the upper end, and an external thread on the lower side surface thereof.
The drainage joint is a substantially cylindrical member, and on the upper end side of the inner peripheral surface is provided with an internal thread screwed with the external thread of the drainage port main body, and at the lower end is a tubular body to be connected Integrally with the part.
The trap tube is a member obtained by bending a tubular body into a substantially U-shape, and is integrally provided at its both ends with a connecting mechanism portion which is connected to the above-mentioned connected mechanism portion and which is connected to the tubular portion.
The J-shaped tube is a tube in which the tube is bent in a substantially J-shaped form, and in use, the shape of J is used upside down. Further, the upstream end of the pipe body is provided with a connected mechanism portion having the same structure as that at the lower end of the drainage joint.
The connection mechanism and the connected mechanism will be described below.
The connection mechanism portion has a substantially cylindrical shape, and includes an inner peripheral surface for housing the connection mechanism portion, and an engagement groove portion formed of a notch along the circumference on the upper side.
The connected mechanism portion has a substantially cylindrical shape, and is provided with an engagement groove portion upward along the outer peripheral surface and a water stop groove portion below. Further, an O-ring for water blocking is externally fitted to the lower water blocking groove.
Moreover, the engagement member described below is utilized for the connection of a connection mechanism part and a to-be-connected mechanism part. The engaging member is an independent member separate from the connection mechanism portion or the connected mechanism portion, and is a member engaged with both the connection mechanism portion and the connected mechanism portion at the time of construction to connect them.
The engagement member is a member having a substantially C-shape in plan view, such as an open portion provided in a part of a cylinder, and is inclined inward on the inner peripheral surface of the upper end portion or the lower end portion. It has a hook-shaped engaging portion with an inclined surface.
The connection work of the connection mechanism and the connected mechanism will be described below.
In advance, the lower engaging portion of the engaging member is engaged with the engaging groove portion of the connection mechanism portion. At this time, the connection mechanism portion and the engagement member are arranged concentrically. From this state, when the connection mechanism portion passes through the inside of the connection mechanism portion, the engagement portion at the upper end of the engagement member abuts on the outer peripheral surface of the connection mechanism portion inserted in the connection mechanism portion As a result, the engagement member is expanded in diameter. When the connected mechanism is completely inserted into the connecting mechanism, the engaging portion on the upper end side of the engaging member is engaged with the engaging groove of the engaged mechanism, and the diameter of the engaging member is reduced. The work is complete. At this time, the connection mechanism portion and the connection mechanism portion are connected in a watertight manner by the O-ring of the connection mechanism portion. In addition, the engagement portion on the upper end side of the engagement member is engaged with the connection mechanism portion, and the lower engagement portion is engaged with the connected mechanism portion, so that the connection mechanism portion is removed from the connected mechanism portion. It can not be removed and is connected rotatably.

The drainage pipe constructed as described above, the drainage pipe, the drainage joint, the trap pipe, the J-shaped pipe, and the drainage pipe using the engaging member are constructed in the wash bowl as follows.
First, the lower end of the drainage port main body is inserted into the attachment hole of the wash bowl, and the lower surface of the buttocks is brought into contact with the upper surface of the attachment hole peripheral edge.
Next, the drainage joint is screwed from below the wash bowl to the male screw of the drainage main body, and the peripheral edge of the attachment hole of the wash bowl is held between the lower surface of the buttocks and the upper end of the drainage joint. Connect and fix the drainage joint to the wash bowl.
Next, after engaging the engagement members with the connection mechanism parts at both ends of the trap pipe, the connection mechanism part at one end of the trap pipe is inserted into the connection mechanism part of the drainage joint, and the drainage joint and the trap pipe Are connected via the engagement member.
Next, the end of the J-shaped tube which is not provided with the connection mechanism portion is cut to a convenient length for connecting to the underfloor piping.
Next, the connection mechanism section at the end of the trap tube on the non-connected side is inserted into the J-tube connection mechanism section to connect the connection mechanism section and the connection mechanism section. The downstream end of the J-shaped pipe is connected to the under-floor piping, and the construction of the drainage piping of the wash bowl is completed.
A drainage trap in which a J-shaped pipe is combined with such a U-shaped trap pipe is called a "S-trap" because the shape of the pipe is such that the letter "S" is turned to the side.
In the connection between the connection mechanism and the connected mechanism of the drainage pipe configured as described above, the connection of the pipe is completed only by inserting or inserting one of the pipes into the other pipe. Compared to bonding, screw connection, etc., installation is simplified and the time required for work is also shortened.
In the present invention, as in the connection mechanism portion and the connection mechanism portion described in this patent document 1, a connection structure or a connection structure in which connection is completed only by moving one tube to one tube in one direction After inserting the other tube into one tube, insert the member for connection fixation from one side or about one rotation or less, preferably quarter rotation of the member for connection fixation about the axis of the inserted tube. A connection that completes the connection by simply rotating it by about a half rotation is referred to as "simple connection".
In the connection mechanism of this patent document 1, the work is completed only by inserting the connection member, so the builder does not need to have technical skill, and as in the case of using the nut member, the water tightness such as the tightening strength There is no need for a jig or the like to confirm whether the connection has been completed. In the prior art of Patent Document 1, the O-ring provided in the drain plug, which is an insertion pipe portion, allows a close connection to be made only by inserting the drain plug into the drain pipe.
In addition, since the pipes are not fixed at all with respect to the rotation around the central axis of the pipe, rotation is possible, and fine adjustment of the position and angle after construction is easy by performing the rotation. At the same time, it is only necessary to remove the engaging member for releasing the connection, and it is also possible to perform pipe connection again in the same procedure as at the time of construction.

However, the tube having the conventional connection mechanism configured as described above has the following problems.
The tubes used for drainage piping are not only straight tubes having straight shapes and tubes whose ends are in a parallel relationship like the trap tube of Patent Document 1, but tubes for achieving the necessary piping layout. By bending the body in the middle, the ends of the tube are not always parallel, such as an elbow tube in which the angle of both ends is bent at an angle of about 90 degrees, a cheese tube in which the tube is branched in a T shape, etc. It is often configured in a shape having an angle instead of an angle.
For example, Patent Document 1 shows a drainage pipe in which a J-shaped pipe forming a substantially J-shape is connected to a trap pipe forming a substantially U-shape, but to a trap pipe forming a substantially U-shape It is well known that a drain pipe having a substantially P-shape, such as a P-shaped side down, is formed by connecting an L-shaped pipe forming a letter-shape.
