Description

  The present invention relates to a repair drain used for repairing an existing drain provided on a balcony, a veranda or the like to discharge rainwater, and in particular, there are a plurality of bent portions whose directions to bend to the drain pipe of the existing drain are different from each other. The present invention relates to a modified drain suitable for use in cases.

  Drains provided on balconies, verandas, etc. as drainage measures such as rainwater have drainage pipes with one end opening on the floor or inner wall of the balcony or veranda, and the other end of the drainage pipe It is connected to a drainage channel or the like, or opens toward them.

  When waterproofing is applied to such an existing drain, usually, a flange portion having a drain hole and a bendable cylinder portion having a base end connected to the flange portion and communicated with the drain hole are provided. Using the modified drain, the cylindrical part of the outer diameter close to the inner diameter of the drainage pipe is inserted into the drainage pipe from the opening located on the balcony, veranda, etc., and extended along the inner wall of the drainage pipe. The collar portion is brought into close water-tight contact with a land surface such as a floor surface or an inner wall surface of a balcony or a veranda surrounding the opening of the drain pipe.

  By the way, in the existing drain, there is a horizontal pulling type that extends downward through an elbow that is a bent portion after the drain pipe extends laterally from one end opening on the inner wall surface of a balcony or a veranda. When the tubular portion of the repair drain is inserted into the drain pipe having such a bent portion, the distal end edge of the distal end portion of the tubular portion forms an annular shape perpendicular to the central axis of the distal end portion, and the rigidity of the distal end portion is increased. Since it is maintained, after the tip of the tube part abuts on the elbow inlet, it stays at the elbow inlet without being deformed along the elbow and prevents further insertion of the tube part. there were.

  For this reason, by cutting away the downward portion of the tip of the cylindrical part of the refurbished drain that is used for the existing drain of the horizontal drawing type, the rigidity against the downward deformation of the tip is lowered, and the tip contacts the elbow inlet. Then, the thing which enabled further insertion of a cylinder part is proposed so that it may deform | transform along the elbow below the elbow bending point (refer patent document 1).

Utility Model Registration No. 3186595

  However, even in the horizontal drain type in which the drain pipe extends sideways from one end that opens to the inner wall surface, the existing drain has an arbitrary position laterally in another direction via an elbow that is a bent portion after extending sideways. There is also one that extends downward through another elbow, and even with a vertical pulling type in which the drain pipe extends in the vertical (vertical) direction from one end opening on the floor surface Rather than being connected to a rain gutter or a drainage channel, etc., there is also a thing that extends to an arbitrary position laterally through an elbow that is a bent portion and then extends downward through another elbow, There may be a case where the drain pipe has a plurality of bent portions having different bending directions.

  In such a case, in the above-described conventional modified drain, since the downward portion of the tip portion of the cylindrical portion is only cut away, the first bent portion of the drain pipe of the existing drain is not bent downward. There is a problem that after the tip of the part comes into contact with the inner surface of the bent part, it cannot be deformed and prevents further insertion of the cylindrical part, and for example, the first bent part of the drain pipe of the existing drain Even if the tip of the tube is bent downward and bent along the first bend, the tip of the tube is bent at the second and subsequent bends bent in a different direction from the first. After contacting the inner surface of the part, there was a problem that it could not be deformed and prevented further insertion of the cylinder part.

  In order to advantageously solve the problems of the conventional modified drain as clarified above, the inventor has intensively studied and arrived at the present invention. That is, the improved drain of the present invention comprises a flange portion having a drainage hole and a bendable cylindrical portion having a base end portion connected to the flange portion and communicated with the drainage hole, and is used for repairing an existing drain. In the repair drain, the tip of the cylindrical portion has a tip edge located on a plane orthogonal to the central axis of the tip, and a plurality of the tips are spaced from each other in the circumferential direction of the tip edge from the tip edge to the tip portion. The incision is formed.

  According to the modified drain of the present invention, the distal end portion of the cylindrical portion has a distal end edge located on a plane orthogonal to the central axis of the distal end portion, and the distal end edge is spaced apart from each other in the circumferential direction of the distal end edge. Therefore, the edge of the drain of the existing drain is deformed so that the tip is bent along the bent portion regardless of the direction of the bent portion of the drain of the existing drain. Even if the bent part is other than downward, or there are multiple bent parts, the cylindrical part is completely inserted into the drain pipe without being blocked by the bent part, and the floor surface of a balcony or veranda surrounding the drain pipe opening In addition, the brim portion can be brought into watertight contact with the land portion such as the inner wall surface.

  In the present invention, it is preferable that each of the plurality of cuts is U-shaped or V-shaped because processing is easy and the rigidity of the leading edge can be sufficiently reduced.

  In the present invention, the number of the plurality of cuts is 2 or more and 4 or less, and the plurality of cuts are spaced apart from each other at equal intervals in the circumferential direction of the tip edge. It is preferable because the rigidity of the leading edge is maintained to such an extent that the leading edge is bent along the bent portion of the existing drain without excessively reducing the rigidity of the edge.

  Embodiments of the present invention will be described below in detail with reference to the drawings by way of examples. Here, FIGS. 1A, 1B, 1C, and 1D are a front view and a rear view showing a horizontal renovation drain for a horizontal draw type existing drain as an example of the renovation drain of the present invention. It is the side view and the perspective view seen from the back side diagonally upward.

  The horizontal renovation drain 1 of this embodiment is an existing horizontal pulling type in which a drain pipe extends laterally from one end opening on an inner wall surface of a balcony, a veranda or the like and then extends downward through an elbow that is a bent portion. An L-shaped plate-like flange portion 2 having a drain hole 2a, and a bendable tube connected to the flange portion 2 and connected to the drain hole 2a. Part 3 is provided.

  Here, the flange portion 2 is formed, for example, by bending a single rectangular lead plate into an L shape having a vertical plate portion 2b and a horizontal plate portion 2c, and at the lower end of the vertical plate portion 2b. A cylindrical protrusion is formed overhanging on the back side, and the drain port 2a is formed by the cylindrical protrusion. Further, the cylindrical portion 3 is made of, for example, a vinyl chloride hose, and a spiral reinforcing rib is integrally formed around the hose to prevent the hose from being crushed.

Two, for example, V-shaped cuts 4 that are spaced apart (around 180 degrees around the central axis of the tip 3b) are formed, for example, arranged on the left and right sides of the central axis of the tip 3b. The cut 4 may be formed in a U shape instead of being formed in the V shape.

  The depth of each cut 4 from the tip edge 3c is preferably 0.4 times or more and 1.2 times or less of the inner diameter of the cylindrical portion 3, for example. If the depth from the leading edge 3c exceeds 1.2 times the inner diameter, the rigidity of the leading edge 3b is too low to bend the leading edge 3b along the bent portion, and the depth from the leading edge 3c is This is because even if the inner diameter is less than 0.4 times the inner diameter, the distal end portion 3b is too rigid and cannot be bent along the bent portion.

  Moreover, it is preferable that the opening width | variety in the front-end | tip edge 3c of each notch 4 shall be 1/24 (15 degree | times in an end surface view) or more and 1/6 (60 degree | times in an end surface view) or less of the circumference of the front-end | tip edge 3c. . If the opening width at the tip edge 3c is less than 1/24 of the circumference of the tip edge 3c (15 degrees in the end view), the tip edge 3c is too rigid and the tip part 3b can be bent along the bent part. If the opening width at the tip edge 3c exceeds 1/6 of the circumference of the tip edge 3c (60 degrees in end view), the rigidity of the tip edge 3c is too low and the tip part 3b is bent along the bent part. Because you can't.
