  However, in the case of the universal drain described in Patent Document 1, a mounting hole is provided at the drain mounting position at the bottom of the eaves bowl, the inner cylindrical body is attached to the mounting hole from above the eaves bowl, and then the outer side is removed from the lower side of the eaves bowl. The work is to fix the cylinder. Usually, since the eaves is attached to a high place, the above work becomes a high place work and is dangerous. Furthermore, if the eaves is made with a front height, or if there is a draining step, the inner cylinder must be attached to the drainage hole from above the eaves. This work is not only difficult because it is difficult to insert the inner cylinder into the drain hole while looking directly at the drain hole, but also the outer cylinder is pressed while holding the flange of the inserted inner cylinder. It was also difficult to screw in.

  An object of the present invention is to provide a universal drain capable of attaching an inner cylindrical body from below the eaves.

  According to the first aspect of the present invention, there is provided an inner cylindrical body having a flange provided on the outer periphery of a cylinder having a male screw provided on the outer peripheral surface, and a flange provided on the outer periphery of the cylinder having a female screw provided on the inner peripheral surface. The outer cylindrical body is screwed with the female thread of the outer cylindrical body into the male thread of the inner cylindrical body, and the peripheral edge portion of the drainage hole formed at the bottom of the eaves is sandwiched between the flanges of both cylindrical bodies. In the universal drain, the notch groove is provided in the flange of the inner cylindrical body from the outer peripheral edge toward the cylinder side.

  The invention according to claim 2 is the universal drain according to claim 1, wherein the outer diameter of the flange of the outer cylindrical body is larger than the outer diameter of the flange of the inner cylindrical body.

  The material of the eaves to which the universal drain of the present invention is applied may be either synthetic resin or metal as long as the bottom surface of the eaves is flat.

  The material of the inner cylinder and the outer cylinder constituting the universal drain in the present invention may be either synthetic resin or metal.

  A notch groove is provided in the flange of the inner cylinder from the outer peripheral edge to the cylinder side. The presence of this notch groove allows the inner cylindrical flange to be connected to the eaves from the lower side of the eaves by using a notch groove provided in the peripheral edge of the drainage hole formed at the bottom of the eaves. Can be inserted into the cage. The thickness and width of the flange may be determined so as not to hinder the elastic deformation of the flange.

  Further, the notch direction of the notch groove of the flange may be a direction located from one point on the outer peripheral edge of the flange to the direction toward the center of the cylinder or the tangential direction to the outer peripheral surface of the cylinder. In addition, if it is provided in the direction close to the tangent, the mounting operation of the free drain can be performed easily.

  The length of the cutout groove may be determined according to the outer diameter of the cylinder of the inner cylindrical body and the inner diameter of the drain hole formed in the bottom of the eaves bowl. The notch groove may be linear or curved.

  In addition, by making the outer diameter of the flange of the outer cylinder larger than the outer diameter of the flange of the inner cylinder, the notch groove provided on the eaves side is not covered with the flange of the outer cylinder and cannot be seen. It looks good from below after installation.

  The cutout groove on the eaves side may be provided outward from one point on the inner periphery of the drain hole formed in the bottom of the eaves. The shape of the cutout groove may be linear or curved. The length should just be more than the circumference position of the virtual circle which is concentric with the drain hole and has the same size as the outer diameter of the flange of the inner cylindrical body. If it does in this way, when the inner cylinder flange is completely inserted into the notch groove on the eaves side, the cylinder of the inner cylinder and the drain hole can be made substantially concentric.

  In the first aspect of the present invention, since the notch groove is provided in the flange of the inner cylindrical body from the outer peripheral edge toward the cylinder side, the flange and the peripheral edge of the drainage hole formed in the bottom of the eaves A similar notch groove is provided, and the inner cylindrical body can be attached from below the eaves by using the notch grooves of both.

  In the invention described in claim 2, since the outer diameter of the flange of the outer cylindrical body is larger than the outer diameter of the flange of the inner cylindrical body, the notch groove provided on the eaves side is covered with the flange of the outer cylindrical body. . For this reason, after mounting the free drain, the cutout groove on the eaves side is not visible from the ground surface side, and the appearance of the eaves is good.

Next, the universal drain of the present invention will be described with reference to the drawings.
FIG. 1 is a half vertical sectional view showing an example of a universal drain according to the present invention. FIG. 2 is a plan view showing an example of the inner cylindrical body of FIG.

The inner cylindrical body 2 has a male screw on the outer peripheral surface 211 of the cylinder 21, and a flange 22 is provided outwardly at one end of the cylinder 21. The outer cylindrical body 3 has a female thread on the inner peripheral surface 311 of the cylinder 31, and a flange 32 is provided outwardly at one end of the cylinder 31. The male screw and the female screw are screwed together. Both the inner cylindrical body 2 and the outer cylindrical body 3 are made of hard vinyl chloride resin.

  As shown in FIG. 2, the flange 22 of the inner cylindrical body 2 is provided with a linear notch groove 23 over the entire length of the flange 22 from one point of the outer peripheral edge 221 toward the center of the cylinder 21. . The width a1 of the cutout groove 23 is set to be slightly larger than the thickness t2 of the bottom 41 of the eaves ridge 4 described later.

  The direction of the cutout groove 23 may be a tangential direction of the circumference of the cylinder 21 as shown in FIG. Further, when the cutout groove 23 is narrow on the cylinder 21 side and is gradually widened toward the outer periphery of the flange 22, the flange of the inner cylinder 2 is attached when the universal drain 1 is attached to the bottom 41 of the eaves 4. The rotation of 22 can be performed more easily.

  As for the side wall of the flange cutout groove 23, the bottom 41 of the eaves 4 at the periphery of the drain hole 5 is inserted into the flange cutout groove 23, and the flange 22 and the bottom 41 of the eaves 4 are substantially parallel to each other. Since these are slid with respect to each other, as shown in FIG. The oblique angle may be changed depending on the thickness of the flange 22 and the thickness of the bottom 41 of the eaves 4 and may be determined by appropriately changing to an appropriate angle including a right angle depending on the situation.

  The outer diameter d2 of the flange 32 of the outer cylindrical body 3 is larger than the outer diameter d1 of the flange 22 of the inner cylindrical body 2, as shown in FIG.

  An example of a procedure for attaching the free drain 1 of FIG. 1 to the bottom of the eaves will be described with reference to FIG. First, as shown in FIG. 5A, the drain hole 5 having an inner diameter that is equal to or slightly larger than the outer diameter of the cylinder 21 of the inner cylindrical body 2 is provided at the drain attachment position of the bottom 41 of the eaves rod 4. A cutout groove 51 on the eaves side is provided from one point on the inner peripheral edge of the drainage hole 5 to the circumference of a virtual circle concentric with the drainage hole and having the same size as the outer diameter of the flange 22 of the inner cylindrical body 2. The width a2 of the cutout groove 51 is made larger than the thickness t1 of the flange 22 of the inner cylindrical body 2.

  At that time, the notch groove 23 on the inner cylindrical body 2 side and the notch groove 51 on the eaves ridge 4 side are provided perpendicular to the flange surface or the bottom surface of the eaves ridge, as shown in FIG. As shown in FIG. 4 (b), when it is provided obliquely with respect to the flange surface or the bottom surface of the eaves, it is possible to more easily attach the inner cylindrical body 2 using both the cutout grooves 23 and 51.

  Next, as shown in FIG. 5 (b), from the lower side of the eaves rod 4, the flange 22 of the inner cylindrical body 2 is set to the upper side, and the flange 22 is parallel to the bottom 41 of the eaves rod 4, so Keep along. The cutout groove 51 on the eaves side is twisted and expanded, and the flange 22 of the inner cylindrical body 2 is inserted into the cutout groove 51 on the eaves side of the bottom 41 of the eaves 4. Further, the notch groove 23 on the flange 22 side is twisted and expanded so as to hit the inner peripheral surface 511 of the drain hole 51 of the eaves rod 4, and the bottom 41 of the eaves rod 4 is inserted into the flange notch groove 23 of the inner cylindrical body 2.

  When the flange 22 of the inner cylindrical body 2 and the bottom 41 of the eaves ridge 4 are fully inserted into the notch grooves 23 and 51, the cylinder 21 of the inner cylindrical body 2 is positioned substantially coaxially with the drain hole 5. come. The flange 22 of the inner cylindrical body 2 and the bottom 41 of the eaves ridge 4 are respectively inserted into the notch groove 51 or the notch groove 23 and twisted. Since the bottom part 41 is rich in both strength and elastic deformation, the twisted deformed shape returns to the original shape after the inner cylindrical body 2 is attached.

Next, in a state where the flange 22 of the inner cylindrical body 2 and the bottom 41 of the eaves 2 are pushed into the notch grooves 23 and 51 respectively, the cylinder 21 of the inner cylinder 2 is inserted into the notch groove 23 of the flange 22. Turn with the side located above the eaves 4 at the top. When the cylinder 21 of the inner cylindrical body 2 is thus rotated, the cutout groove 23 of the flange 22 moves while sliding on the inner surface of the peripheral edge of the drain hole 5, and the inner cylinder 2 on the rear side of the cutout groove 23. As the flange rotates, the flange 22 passes through the notch groove 51 on the eaves rod 4 side, and the entire flange 22 of the inner cylindrical body 2 moves above the bottom 41 of the eaves rod 4.

  When the entire flange 22 of the inner cylindrical body 2 moves on the inner surface of the bottom 41 of the eaves rod 4, the female screw of the outer cylindrical body 3 is screwed into the male screw of the inner cylindrical body 2 protruding downward from the drain hole 5 of the eaves rod 4. The attachment of the free drain is completed by sandwiching the peripheral edge of the drain hole 5 of the eaves 4 between the flanges 22 and 32 of both cylindrical bodies.

  Since the outer diameter d2 of the flange 32 of the outer cylindrical body 3 is made larger than the outer diameter d1 of the flange 22 of the inner cylindrical body 2, the flexible drain 1 is attached to the eaves 4 and then the mounting location is looked up from below. However, the cutout groove 51 on the eaves 4 side is not visible and looks good.

  The inner cylinder 2 may be attached by applying an adhesive or a sealing material to the inner surface of the eaves or the flange surface of the inner cylinder that is in contact with the eaves. When screwing together, an adhesive, a sealing material, or a waterproof seal may be used in combination between the flange surface of the outer cylindrical body and the bottom of the eaves so as to ensure the waterproof.
