Description

[Detailed description of the invention] The present invention is to close the lower end opening of the curved cylindrical body having a rectangular opening with a plate, and to open a circular drainage hole in the plate, and to provide a downward The elbow body has an annular drainage projecting piece extending downward and having cuts at predetermined intervals in the circumferential direction, and an upper opening of the straight cylindrical body having a square opening. is closed with a plate, and a circular opening into which the annular drainage protrusion is to be fitted is opened in the plate, and a circular opening into which the annular drainage protrusion is to be fitted is formed on the periphery of the opening, and a circular opening is formed in the circular opening into which the annular drainage protrusion is to be fitted. It consists of a rotating cylinder with an expanding annular protrusion protruding downward,
This is related to a gutter elbow made by fitting an annular drainage protrusion into an annular protrusion and rotatably attaching a rotary tube to the elbow body, and its main purpose is to connect rectangular vertical gutters. The purpose is to improve workability.

When bending a vertical gutter with a gutter elbow, unlike an elbow for a round gutter, the elbow for a square gutter requires adjustment of the torsion angle as well as the bending angle, so several types of gutter elbows are required. As a result, the construction was not only complicated, but also not economical.

This invention was devised in view of the above, and
Embodiments of the invention shown in the drawings will be described below. Fig. 1 is an exploded perspective view of the gutter elbow of the invention, Fig. 2 is a sectional view of the same, and Fig. 3 is a partially enlarged sectional view of the same. , A in the figure is the elbow body, and the lower end opening of the curved cylindrical body 1 having a rectangular opening is closed with a plate 2, and a circular drainage hole 3 is opened in the plate 2. An annular drainage protrusion 5 is protruded downward from the periphery of the hole 3 and has cuts 4 extending downward and at predetermined intervals in the circumferential direction. It is a cylinder,
The upper opening of the straight cylindrical body 6 having a square opening is closed with a plate 7, and a circular opening 8 into which the annular drainage protrusion 5 is inserted is opened in the plate 7. The elbow body A and the rotary cylinder B are formed by protruding downwardly an annular protrusion 9 that expands downward to fit into the annular drainage protrusion 5 on the periphery. By fitting the annular drainage protrusion 9 into the annular protrusion 9, the annular drainage protrusion 9 is rotatably mounted.

As is clear from the above, in the gutter elbow of the present invention, the lower end opening of the curved cylindrical body 1 having a rectangular opening is closed by the plate 2, and the circular drainage hole 3 is provided in the plate 2. , an elbow main body A having an annular drainage projecting piece 5 extending downward from the periphery of the drainage hole 3 and having cuts 4 formed at predetermined intervals in the circumferential direction; , the upper opening of the straight cylindrical body 6 having a rectangular opening is closed with a plate 7, and a circular opening 8 into which the annular drainage protrusion 5 is to be fitted is opened in the plate 7; It consists of a rotary cylinder B having a circular ring-shaped protrusion 9 projecting downward, which expands downward so as to fit into the circular drainage protrusion 5, on the periphery of the annular drainage protrusion 5. Insert the annular drainage protrusion 5 into the elbow body A and attach the rotary cylinder B.
Although the gutter elbow and the vertical gutter connected thereto have different opening positions, the rotary tube B of the gutter elbow is attached to the cylindrical drainage protrusion 3. Because they are connected by rotating around the axis, construction is greatly simplified.
In addition, there is no need for multiple gutter elbows with different torsion angles, which improves economic efficiency.
Furthermore, a rotary tube B is attached to the elbow body A with an annular protrusion 9.
Since they are integrally connected by the elastic fitting of the annular drainage protrusion 5 into the drain plate, it has excellent features not found in conventional products, such as there is no risk of separation or water leakage due to aging.
