Description

[Detailed description of the invention] This invention relates to the structure of the elbow connection part of a water collector, and the purpose of the invention is to selectively connect both a large-diameter elbow and a small-diameter elbow. Moreover, it is an object of the present invention to provide a structure for an elbow connection portion of a concentrator that can be formed entirely by integral molding of synthetic resin.

The present invention will be explained in detail below using examples.

An outer cylinder 3 is integrally formed on the outer periphery of an inner cylinder 2 for drainage at the lower part of the water collector body 1 with a gap therebetween.

Here, the lower end of the inner cylinder 2 protrudes below the lower end of the outer cylinder 3.

An annular groove 4 is formed on the upper outer periphery of the outer cylinder 3.
An annular groove 4 is formed from the lower end on the outer surface of the
The vertical grooves 5 extending thereto are recessed.

The width of the vertical groove 5 is such that a convex portion 7 projecting from the upper inner surface of the large-diameter elbow 6 can be inserted therein.

At the lower part of the inner circumference of the outer cylinder 3, a plurality of protrusions 8 are annularly protruded along the circumferential surface, and the distance between the protruding tip of each protrusion 8 and the outer surface of the inner cylinder 2 is the same as that of a small diameter elbow. The wall thickness is equal to or slightly longer than No. 9.

The width between the ends of any adjacent protrusions 8 among the plurality of protrusions 8 is such that the protrusion 10 protruding from the upper outer surface of the small-diameter elbow 9 can be inserted, and this portion is the width for inserting the protrusion 10 into which the protrusion is inserted. In the illustrated embodiment, there are a total of two protrusion insertion gaps 12 at the front and rear.

Further, the width between the end portions of the remaining adjacent protrusions 8 is smaller than the width of the convex portion 10 of the small diameter elbow 9.

Immediately above the protruding part 8 on the wall of each outer cylinder 3 that has been cut, there is a piece whose circumferential position is the same as that of the protruding part 8, the width of the protruding part 8 is circular, and it corresponds parallel to the protruding part 8. The hole 11 is provided so as to penetrate inside and outside.

The water collector A having the above structure is integrally molded by injection molding of synthetic resin.

That is, molding is performed by clamping the upper and lower molds and the side molds, and in this case, the hole 11 of the water collector A formed becomes a hole for removing the side mold.

In this way, the present invention has a protruding portion 8 on the inner surface of the lower part of the outer cylinder 3.
Even though the side mold is provided protrudingly, the side mold can be removed from the hole 11, so the water collector A can be integrally molded from synthetic resin.

A small diameter elbow 9 or a large diameter elbow 6 can be connected to the water collector A as described above.

That is, in order to connect the small-diameter elbow 9, the upper part of the small-diameter elbow 9 is placed below the inner cylinder 2 of the water collector A, and the protrusion 10 protruding from the upper inner surface of the small-diameter elbow 9 is inserted into the protrusion insertion gap 12. In this state, the small diameter elbow 9 is fitted into the inner cylinder 2, and the protrusion 10 is inserted into the protrusion insertion gap 12.
When the small diameter elbow 9 is moved upward and the convex part 10 is located above the protruding part 8, the small diameter elbow 9 is rotated and the convex part 1 is moved upward.
0 is placed on an arbitrary protrusion 8.

In this case, the gap between the ends of the protrusion 8 other than the protrusion insertion gap 12 is narrower than the protrusion 10, so that the protrusion 10 will not fall therefrom.

In addition, if two protrusion insertion gaps 12 are provided and the button is pressed as in the embodiment shown, the small diameter elbow 9 can only be attached and removed from the two locations.

In addition, in order to connect the large diameter elbow 6, the upper part of the large diameter elbow 6 is placed below the outer cylinder 3 of the water collector A, and the large diameter elbow 6 is
The convex part 7 protruding outward from the upper part of the cylinder is directed downward of the vertical groove 5, and in this state, the large-diameter elbow 6 is fitted into the outer cylinder 3, and the convex part 7 is inserted into the vertical groove 5. Move the elbow 9 upwards, and when the convex part 7 is located in the communicating area between the vertical groove 5 and the annular groove 4, rotate the large diameter elbow 9 and place the convex part 7 on the lower wall of the annular groove 4. It is something.

If two vertical grooves 5 are provided as in the example shown in the figure, 2
The large diameter elbow 6 can only be attached and removed from the location.

Note that an eaves gutter (not shown) is connected to the upper part of the water collector A.

Further, as the large diameter elbow 6, for example, 75y5 is used, and as the small diameter elbow, 60. S is used.

In the present invention, since it is constructed as described above, it is possible to selectively attach both the large diameter elbow and the small diameter elbow, and it is also possible to selectively attach both the large diameter elbow and the small diameter elbow. The water collector has a structure that can be formed by integral molding of synthetic resin.
