DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a universal drain.

[0002]

2. Description of the Related Art Conventionally, a universal drain has been used in Japanese Utility Model Publication No. 63-48.
No. 740 is known. This free drain consists of an upper inner cylinder and a lower outer cylinder. The upper inner cylinder consists of an upper flange and an upper cylinder provided below the upper flange. A male screw is provided on the outer peripheral surface of a lower end portion of the upper cylindrical body, and the lower outer cylinder body has a lower flange portion protruding outward at an upper end portion, and a lower cylinder provided below the lower flange portion. And a female screw provided on an inner peripheral surface of an upper end portion of the lower cylindrical body. In this free drain, the upper cylinder is inserted into the drainage hole of the eaves gutter from above, the female screw of the lower cylinder is screwed into the male screw of the upper cylinder protruding below the drainage hole, and screwed up. The inner cylinder of the mold is joined to the outer cylinder of the lower mold, and the upper and lower flanges are used by being sandwiched between eaves gutters. Since this free drain is clamped in the drainage hole drilled in the eaves gutter at the upper and lower flanges of the upper and lower outer cylinders from above and below,
It is firmly fixed to the eaves gutter, easy to install, and convenient.

[0003]

Generally, the work of attaching a free drain to an eaves gutter is performed at a high place at the eaves of a building. In the conventional free drain described in Japanese Utility Model Publication No. 63-48740, a male screw on the outer peripheral surface of the lower end of the upper inner cylinder is screwed into a female screw on the inner peripheral surface of the upper end of the lower outer cylinder, An eaves gutter is sandwiched between the upper and lower flanges to perform the mounting operation.
However, in the high places at the eaves, the scaffolding is poor, and when screwing the male screw of the upper inner cylinder that projects downward from the eave gutter into the female screw of the lower outer cylinder, screw in from below. When the female screw of the lower outer cylinder is turned, the male screw of the upper inner cylinder rotates together, making it difficult to screw in. Even if the upper upper inner cylinder is held down, the hand is held at a high place at the eaves. There is a problem that it is hard to see, it is hard to reach, and the screwing work does not go smoothly.

[0004] Therefore, an object of the present invention is to provide a simple structure in which the male screw of the upper inner cylinder does not rotate even when the female screw of the lower outer cylinder is turned, even in a place where the scaffold is high at the eaves. To provide a universal drain that can be attached to an eaves gutter.

[0005]

The upper and lower inner cylinders of the present invention may be made of any suitable material. The lower inner cylinder can be integrally molded by an injection molding method, and the integrally molded one is preferable because it is lightweight and has a good appearance.

The shape of the upper flange of the present invention is such that when the upper flange is rotated around the center of the drain hole, the longest part of the upper flange hits the lower part of the side wall of the eaves gutter, If the rotation can be stopped, an appropriate shape may be used.For example, the cross-sectional shape of the entire shape of the upper mold flange portion is made into an elliptical plate-like body, and one of the elliptical plate-like bodies in the longitudinal direction is formed. The upper cylindrical body is attached to the end, and the length of the longest part of the width of the upper flange (H in FIG. 2)
Is longer than the longest length (N in FIG. 2) from the inner diameter of the drainage hole formed in the eaves gutter to the lower part of the side wall of the eaves gutter.
When rotated about the axis of the upper cylinder, the end of the longest part of the upper flange hits the lower part of the side wall of the eaves gutter, and the rotation can be stopped.

Further, as shown in FIGS. 3 and 4, the cross-sectional shape of the entire shape of the upper mold flange is made into a rectangular plate such as a triangle or a quadrangle, and the longitudinal direction of these rectangular plate members is changed. The upper cylinders are attached to one end of the cylinder, and the length from these upper cylinders to the square corners (H1 in FIG. 3 or H2 in FIG. 4)
Is longer than the longest length (N1 in FIG. 3 or N2 in FIG. 4) from the inner diameter of the drainage hole formed in the eaves gutter to the lower part of the side wall of the eaves gutter, When pivoted to the center, the end of the longest part of the upper flange hits the lower part of the side wall of the eaves gutter, which can be stopped, which is preferable.

Further, if a cross-shaped dust evasion is attached to the upper end of the drainage hole of the eaves gutter, dust and dead leaves accumulated in the eaves gutter are stopped by the trash avoidance, and the downspout of the downspout connected to the universal drain is prevented. This is preferable because clogging can be prevented.

[0010]

[Function] An external thread is provided on the outer peripheral surface of the upper cylinder of the upper mold inner cylinder, and the length of the longest part of the upper flange is from the inner diameter of the drainage hole of the eave gutter to the lower part of the side wall. Since the female screw is provided on the inner peripheral surface of the lower cylinder of the lower outer cylinder, the upper cylinder is inserted into the drain hole from above the eaves gutter, and the upper cylinder is When the female screw of the lower cylinder of the lower outer cylinder is screwed into the male screw from below the eaves gutter, the upper inner cylinder rotates slightly with the lower outer cylinder. Part of the upper mold flange in the longitudinal direction of the upper mold flange hits the lower part of the side wall of the eaves gutter, stops the upper mold inner cylinder and prevents the male screw of the upper mold inner cylinder from rotating together. The outer cylinder is easily screwed in, and the eaves gutter is sandwiched between the upper and lower flanges, so that the universal drain can be easily attached to the eaves gutter.
