Description

The present invention relates to a pipe body provided with a connection mechanism used for drainage pipes and the like, and more specifically, to provide a connection mechanism that increases the degree of freedom in pipe layout in a pipe body provided with a connection mechanism for simple connection. It is about the provided tube.

Conventionally, in equipment that generates drainage by use (hereinafter referred to as "drainage equipment") such as sinks, washbasins, and bathtubs, in order to treat the generated drainage to the sewage side, drainage pipes that treat the drainage of drainage equipment have been used. Widely known.
The drainage pipes of these drainage devices connect various shapes such as straight pipes, curved pipes, or pipes called trap pipes in which the pipes are bent into a U shape, and the ends of the pipes. It is done by.
Usually, for the connection of the end of this tube, adhesion using an adhesive or screw connection using a packing and a nut member is often used, but these methods have the following problems. was there.

When connecting pipes by gluing with an adhesive, it may take a considerable amount of time for the applied adhesive to harden and complete the gluing, and it may be necessary to interrupt the work each time the gluing is performed. rice field.
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 body, the adhesive hardens the pipe so that the adhesive position does not shift due to these stresses. It may be necessary to fix the pipe body with a fixing stand or the like until the bonding is completed, and to remove the fixing stand after the curing of the adhesive is completed.
In addition, for the connection of the pipe body, it is necessary to make a watertight and reliable connection so that the gas and liquid flowing inside, especially the liquid such as drainage, do not leak. There was a problem that it required the skill and skill of the builder to do it, and it was difficult to make a watertight connection.
In addition, once the adhesive has hardened, it is not possible to disconnect the pipe body again or move the connection angle / position, so fine adjustment of the piping after construction, damage to the piping members, etc., and replacement of the members, etc. There was a problem that it became difficult.

Therefore, there has been proposed a drainage pipe capable of easily and surely connecting a watertight pipe body as described in Patent Document 1, and capable of separating pipe members and finely adjusting the position even after construction.
The pipe body provided with the connection mechanism described in Patent Document 1 is composed of a drainage port main body, a drainage joint, a trap pipe, and a J-shaped pipe described below, and is installed in the washbasin described below.
The top and bottom in the following description are based on the top and bottom of the drawings in Patent Document 1.
The washbasin is a box body with an open upper part, and has a mounting hole on the bottom surface through which the drainage port main body is inserted.
The drainage port main body has a substantially cylindrical shape, and is provided with a flange portion protruding in the outer peripheral direction at the upper end and a male screw on the lower side surface thereof.
The drainage joint is a substantially cylindrical member, and has a female screw screwed with a male screw of the drainage port main body on the upper end side of the inner peripheral surface, and a connected mechanism portion described later is a pipe body at the lower end. Prepare for one with the part.
The trap tube is a member in which the tube body is bent into a substantially U-shape, and both ends thereof are provided with a connection mechanism portion that makes a simple connection corresponding to the connected mechanism portion integrally with the tube body portion.
The J-shaped tube is a tube body in which the tube body is bent into a substantially J-shape, and the J-shape is turned upside down when used. 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 unit and the connected mechanism unit will be described below.
The connection mechanism portion has a substantially cylindrical shape, and is provided with an inner peripheral surface for accommodating the connection mechanism portion, and is further provided with an engagement groove portion formed by a notch along the circumference.
The connected mechanism portion has a substantially cylindrical shape, and is provided with an engaging groove portion above and a water blocking groove portion below along the outer peripheral surface. Further, an O-ring for stopping water is externally fitted in the lower water stopping groove portion.
Further, the engaging member described below is used for connecting the connecting mechanism portion and the connected mechanism portion. The engaging member is an independent member separate from the connecting mechanism portion and the connected mechanism portion, and is a member that engages with both the connecting mechanism portion and the connected mechanism portion and connects them at the time of construction.
The engaging member is a member having a substantially C-shaped plan view, such as a cylinder having an open portion provided in a part thereof, and the inner peripheral surface of the upper end portion and the lower end portion thereof is inclined inward. It is provided with a claw-shaped engaging portion having an inclined surface.
The connection work between 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 connecting mechanism portion. At this time, the connecting mechanism portion and the engaging member are arranged concentrically. From this state, when the connected mechanism portion is passed through the inside of the connecting mechanism portion, the engaging portion at the upper end of the engaging member comes into contact with the outer peripheral surface of the connected mechanism portion inserted into the connecting mechanism portion and is directed toward the outer peripheral direction. It will be pushed and the diameter of the engaging member will increase. When the connected mechanism portion is completely inserted into the connecting mechanism portion, the engaging portion on the upper end side of the engaging member engages with the engaging groove portion of the engaged mechanism portion, and the diameter of the engaging member is reduced to connect. The work is completed. At this time, the connection mechanism portion and the connected mechanism portion are watertightly connected by the O-ring of the connection mechanism portion. Further, the engaging portion on the upper end side of the engaging member is engaged with the connecting mechanism portion, and the lower engaging portion is engaged with the connected mechanism portion, so that the connecting mechanism portion is disconnected from the connected mechanism portion. It is non-detachable and rotatably connected.

The drainage port main body, the drainage joint, the trap pipe, the J-shaped pipe, and the drainage pipe using the engaging member configured as described above are installed in the washbasin as follows.
First, the lower end of the drainage port body is inserted into the mounting hole of the washbasin, and the lower surface of the flange portion is brought into contact with the upper surface of the mounting hole peripheral surface.
Next, the drainage joint is screwed from below the washbasin into the male screw of the drainage port body, and the peripheral edge of the mounting hole of the washbasin is sandwiched between the lower surface of the flange and the upper end of the drainage port to hold the drainage port body and the upper end of the drainage joint. Connect and fix the drainage joint to the washbasin.
Next, after engaging the engaging member with the connection mechanism at both ends of the trap pipe, the connection mechanism at one end of the trap pipe is inserted into the connection mechanism of the drainage joint to form the drainage joint and the trap pipe. Is connected via an engaging member.
Next, the end of the J-shaped pipe on the side not provided with the connected mechanism portion is cut to a length convenient for connecting to the underfloor pipe.
Next, the connection mechanism portion at the end of the trap tube on the side where the connection is not made is inserted through the connected mechanism portion of the J-shaped pipe to connect the connection mechanism portion and the connected mechanism portion. , The downstream end of the J-shaped pipe is connected to the underfloor pipe, and the construction of the drainage pipe of the washbasin is completed.
A drain trap in which a J-shaped pipe is combined with such a U-shaped trap pipe is called an "S trap" because the shape of the pipe is such that the S-shape is tilted sideways.
In the connection between the connection mechanism part and the connected mechanism part of the drainage pipe configured as described above, the connection of the pipe body is completed only by inserting or inserting one pipe body into the other pipe body. Compared to bonding and screw connection, construction is easier and the time required for work is shortened.
In the present invention, like the connection mechanism portion and the connected mechanism portion in Patent Document 1, the connection structure is such that the connection is completed only by moving one tube body in one direction with respect to the other tube body. After inserting the other tube into one tube, insert the connection fixing member from one side, or rotate the connection fixing member about one rotation or less, preferably a quarter rotation, around the axis of the inserted tube. A connection that completes the connection by rotating it about half a turn is called a "simple connection".
In the connection mechanism of Patent Document 1, since the work is completed only by inserting the connection member, the builder does not need technical skill, and the tightening strength and the like are watertight as in the case of using the nut member. No jig or the like is required to confirm whether or not the connection is completed. In the conventional example of Patent Document 1, the O-ring provided in the drain plug, which is the insertion pipe portion, makes a close connection only by inserting the drain plug into the drain pipe.
In addition, regarding the rotation around the central axis of the pipe body, since the pipe bodies are not fixed at all, it is possible to rotate, and it is easy to fine-tune the position, angle, etc. after construction by rotating. At the same time, to disconnect the connection, it is only necessary to remove the engaging member, and it is also possible to reconnect the pipes by the same procedure as at the time of construction.

The pipe body used for the drainage pipe is not only a straight pipe having a straight shape or a pipe body having parallel ends like the trap pipe of Patent Document 1, but also a pipe for achieving the required pipe layout. The ends of the pipes are not necessarily parallel to each other, such as an elbow pipe that bends the angle of both ends to an angle of about 90 degrees by bending the body in the middle, and a cheese pipe that branches the pipe into a T shape. It is often configured in a shape with an angle instead of.
For example, Patent Document 1 shows a drainage pipe in which a trap pipe having a substantially U shape is connected to a J-shaped pipe having a substantially J shape. It is also well known that a drainage pipe has a substantially P-shape, which is like a P-shaped tilted sideways by connecting an L-shaped pipe that forms a shape. A drain trap in which an L-shaped pipe is combined with such a U-shaped trap pipe is called a "P trap" because the shape of the pipe is such that the P-shape is tilted sideways.
In the case of this P trap, the pipe on the sewage side is piped in the wall surface in the side surface direction, and the drainage pipe is completed by connecting the pipe on the downstream side of the trap to the wall surface.

It is not possible to adjust the height position of the edges. Further, if the connecting mechanism portion or the connected mechanism portion is cut from the pipe body for position adjustment, the connection itself between the pipe bodies becomes impossible in the first place. Therefore, the end of the pipe body provided with the connection mechanism portion such as the pipe of the P trap and the end portion of the pipe body provided with the connected mechanism portion are not parallel to the connection mechanism portion and the connected mechanism portion.

The drainage pipe using the drainage port main body 4, the drainage joint 5, the trap pipe 6, the L-shaped pipe 7, and the engaging member 3 configured as described above is installed in the washbasin S as follows.
First, the lower end of the drainage port main body 4 is inserted into the mounting hole S1 of the washbasin S, and the lower surface of the flange portion 4a is brought into contact with the upper surface of the peripheral surface of the mounting hole S1.
Next, the drainage joint 5 is screwed from below the washbasin S to the male screw of the drainage port main body 4, and the peripheral edge of the mounting hole S1 of the washbasin S is sandwiched between the lower surface of the flange portion 4a and the upper end of the drainage joint 5. As a result, the drainage port main body 4 and the drainage joint 5 are connected and fixed to the washbasin S.
Next, after engaging the engaging members 3 with the connecting mechanism portions at both ends of the trap pipe 6, the connecting mechanism portion 1 at one end of the trap pipe 6 is inserted into the connected mechanism portion 2 of the drainage joint 5. In this way, the connecting mechanism portion 1 and the connected mechanism portion 2 are connected via the engaging member 3.
Next, the end portion of the L-shaped pipe 7 on the side not provided with the male screw portion 7b is cut to a length convenient for connecting to the wall drainage pipe W. Since the L-shaped tube main body 7a is made of a hard resin such as polypropylene, it can be cut relatively easily with a metal cutting jig such as a saw.
Next, the nut member 12 is screwed into the male threaded portion 7b of the L-shaped tube main body 7a.
Next, the adapter member 10 is screwed into the male screw portion 7b of the L-shaped tube main body 7a, and the screwing is advanced until the end portion of the adapter member 10 abuts on the end portion of the nut member 12. As described above, when the adapter member 10 and the nut member 12 are in contact with each other, the threads of both are not continuous. Therefore, when the adapter member 10 is in contact with the nut member 12, the adapter member is formed. The 10 and the nut are integrated and the screwing does not proceed. As a result, the adapter member 10 is strongly in contact with the nut member 12, so that the position of the adapter member 10 is fixed. At this time, the O-ring R of the water stop groove portion 8 of the L-shaped tube main body 7a comes into contact with the inner surface of the adapter member 10, so that the two are watertightly connected.
Next, the connection mechanism portion 1 at the end of the trap tube 6 on the side where the connection is not made is inserted into the connected mechanism portion 2 of the L-shaped pipe 7, and is connected to the connection mechanism portion 1. The construction of the drainage pipe of the washbasin S is completed by connecting the mechanism portion 2 and the downstream end portion of the L-shaped pipe 7 to the branch pipe portion W1 of the wall drainage pipe W.
In this embodiment, when the construction is completed, the axial direction of the end pipe body of the L-shaped pipe 7 which is the second pipe body and which does not have the connected mechanism portion 2 is the connection mechanism portion 1 when the construction is completed. And, it is configured to have an angle of about 90 degrees with respect to the axial direction of the connected mechanism portion 2.

In the pipe body provided with the connecting mechanism configured as described above, the connected mechanism portion 2 of the L-shaped pipe 7 is positioned to advance the screwing of the nut member 12 as shown in FIGS. 8 and 9. By changing the position, the position of the adapter member 10 with respect to the L-shaped tube main body 7a when the screw tightening is completed can be moved along the axis of the tube end portion.
That is, the connected mechanism portion 2 of the L-shaped tube 7 of the present embodiment is provided with a moving mechanism for moving the position along the axis of the tube end portion, and the moving mechanism provides the covering of the L-shaped tube 7. The connection mechanism portion 2 can be moved in position with respect to the end portion on the side not provided with the connected mechanism portion 2.
By using the moving mechanism of the connected mechanism portion 2, the connected mechanism portion 2 can be moved to a position suitable for construction. In the case of this embodiment, the appropriate position for the construction of the connected mechanism portion 2 is that the height position of the horizontal portion on the downstream side of the L-shaped pipe 7 is the branch pipe portion W1 of the wall drainage pipe W at the completion of the construction. It is a position where the connected mechanism portion 2 is fixed to the L-shaped pipe main body 7a so as to be substantially the same and to be arranged so as to be slightly inclined toward the wall due to natural drainage.

Further, since the rotation around the central axis of the pipe body is not fixed at all, it is possible to rotate, and it is easy to make fine adjustments such as the position and angle after construction by performing the rotation. Further, regarding the disconnection of the connection mechanism, the connection of the connection mechanism is released by expanding the diameter of the C-shaped open portion of the engaging member 3 and disconnecting from the tube body from the enlarged diameter portion. It is also possible to reconnect the pipes using the same procedure as during construction.
