Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a corner drain which is attached to a trough and has a convenient structure.

[0002]

[Prior art]

 When a corner trough is provided in a trough made of conventional metal and synthetic resin composite material, the trough is aligned with the trough, and a complicated cut is made on site to make the end of the trough into the trough. Sheet metal work was performed well, and tacking work was performed at appropriate intervals, and the sealing material was applied so as to cover the ends and tack heads. It took quite a lot of skill and construction man-hours.

[0003]

[Problems to be solved by the device]

 The present invention relates to a corner drain which is suitable for drainage in a trough, and which can be selected by selecting a drop hole, cutting out a hole in the trough, and attaching the hole by a simple procedure.

[0004]

[Means for Solving the Problems]

 The present invention is a combination of a trough and a corner drain fixed to a part of the trough, wherein the corner drain is formed on an inner wall of the trough of an opening formed by cutting out a part of the trough corner. An inner cylindrical portion that includes an inner wall engaging portion that engages with the inner wall engaging portion, a guide portion that extends outward from the inner wall engaging portion, and an outer screw portion that is formed at a distal end portion of the guide portion; An outer wall engaging portion that engages with an outer wall of the trough gutter opening, an outer guide portion that extends outward from the outer wall engaging portion while enclosing the inner tubular portion from the outside, and an outer guide portion. An outer tubular portion including a flange portion formed at the end portion of the inner tubular portion, an inner threaded portion that is screwed into the outer threaded portion of the inner tubular portion, and a flange portion that abuts the flange portion of the outer tubular portion. And a rotary member having: a combination of a trough and a corner drain.

【Example】

 The present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing a combination of a trough and a corner drain according to the present invention, (a) is a sectional view of such a combination, and (b) is a conceptual diagram of such a combination. The corner drain according to the present proposal includes an inner cylinder portion A, an outer cylinder portion B, and a rotating member C. The inner tubular portion A is an inner wall engaging portion 2 that engages with an inner wall of the trough of the opening formed by cutting out a part of the trough corner, and a guide portion 3 that extends outward from the inner wall engaging portion. And an outer screw portion 4 formed at the end of the guide portion 3. Further, the outer tube portion B extends outward from the trough gutter while surrounding the inner tube part from the outer wall engaging portion 6 that engages with the outer wall of the trough gutter of the trough opening portion and from the outer wall engaging portion. It is composed of an outer guide portion 7 and a flange portion 8 formed at the end portion of the guide portion. The rotating member C is composed of an inner threaded portion 9 that is screwed into the outer threaded portion 4 of the inner tubular portion, and a flange portion 10 that is in contact with the flange portion of the outer tubular portion.

A method for implementing the present invention will be described. In carrying out the present invention, select a suitable drainage for the trough, cut out the hole in the trough, and use the corner drain according to the present invention and, if desired, the inner wall of the corner drain. Insert a sealing material between each of the joint and outer wall engaging part and the wall of the trough, and tighten with a simple tool. Description will be made with reference to FIG. First, the corner of the trough D is cut. Next, the inner wall engaging portion 2 of the corner drain is brought into contact with the inner wall D through a waterproof sealing material if desired. Next, by tightening the inner screw portion 9 of the rotating member C, the seat plate of the outer wall engaging portion 6 of the corner drain is pressed against the outer wall of the trough D, whereby the inner wall of the trough D and the inner wall of the corner drain are engaged. The joint portion 2 is crimped. This enables reliable construction of corner drains without the need for skilled skills.

It is desirable that the tubular portion B of the corner drain has a margin and that the tubular portion has an elliptical shape so that the pressure bonding due to the thickness of D is always uniform. Further, it is desirable that the end portion has a width so that the force of the end portion of C can be easily received. Furthermore, it is preferable that the end of the portion of the rotating member C that comes into contact with the tubular portion B also has a width so that the end of the tubular portion B can be pressed uniformly at all times. It is desirable to match the inner diameter of the vertical gutter attached to the end of the threaded portion associated with the rotating member C of the corner drain with the same.
