Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a connection structure between a water collector and an elbow that allows the elbow to be reliably attached to the lower end of the water collector.

[Background technology]

Conventionally, when connecting an elbow to the lower part of a water collector attached to a rain gutter, etc., a connecting piece 9 is provided at the lower end of the water collector 4 as shown in FIG.
A locking hole 11 is provided at the opening edge of the drain port 10, and a locking piece 12 is provided protruding from the outer periphery of the upper end of the elbow 6, and the locking piece 12 of the elbow 6 and the locking hole 11 are aligned. A method has been adopted in which the locking piece 12 is inserted into the connecting piece 9 through the locking hole 11 and locked. However, in this method, the locking piece 1
2 and the locking hole 11, which makes the installation work troublesome, and if the position of the locking piece 12 and the locking hole 11 match by rotating the elbow 6, the elbow 6 The drawback was that it could come off unexpectedly.

[Purpose of invention]

The present invention was developed in view of the above points, and the purpose is to provide a connection structure between a water collector and an elbow, which is easy to connect and can be connected reliably without the elbow coming off. It is something to do.

[Disclosure of invention]

That is, in the connection structure between a water collector and an elbow according to the present invention, a ring-shaped connector 1 is formed by a large C-shaped connection piece 2 and a small connection piece 3, and a water collector 4 is connected to the elbow.
An engaging protrusion 5 is provided protrudingly on the outer periphery of the lower end of the elbow 6, and an engaging piece 7 is provided protrudingly provided on the outer periphery of the upper end of the elbow 6.
An elbow 6 is disposed on the lower side of the connector, and the connecting tool 1 is disposed on the outside of the engaging protrusion 5 and the engaging piece 7, and the connecting tool 1 is disposed on the inner peripheral surface of at least one of the large connecting piece 2 and the small connecting piece 3. An engaging recess 8 is provided in which the engaging protrusion 5 of the water collector 4 and the engaging piece 7 of the elbow 6 are inserted.
The above object is achieved by inserting and engaging the connecting device 1, which is formed into a ring shape by the large connecting piece 2 and the small connecting piece 3, and connecting it by placing it between the water collector 4 and the elbow 6. It is.

The present invention will be explained in detail below using examples. As shown in FIGS. 1 and 2, a ring-shaped connector 1 is divided into two parts, a large C-shaped connection piece 2 and a small connection piece 3, which are not engaged with the inner peripheral surface of the connector 1. Matching place 8
is recessed around the entire circumference. On the other hand, water collector 4
An engagement protrusion 5 is provided on the outer periphery of the lower end of the elbow 6, and an engagement piece 7 is provided on the outer periphery of the upper end of the elbow 6.

Therefore, when connecting the elbow 6 to the water collector 4 attached to a rain gutter, etc., as shown in FIG. 8 is fitted, this elbow 6 is attached to the water collector 4.
The engaging protrusion 5 of the water collector 4 is fitted into the engaging recess 8 of the large connecting piece 2. Next, as shown in FIGS. 4 and 5, the small connecting piece 3 is fitted into the large connecting piece 2 or bonded using an adhesive to form the ring-shaped connecting tool 1. In this way, the engaging protrusion 5 of the water collector 4 and the elbow 6
The engaging pieces 7 of the connecting tool 1 are both inserted into the engaging recess 8 of the connecting tool 1, and the engaging protrusion 5 of the water collector 4 is engaged with the engaging upper piece 13 of the connecting tool 1, so that the connecting tool 1 While being held by the water collector 4, the engagement piece 7 of the elbow 6 is engaged with and held by the lower engagement piece 14 of the connector 1. Furthermore, the elbow 6 can be rotated through 360 degrees and does not cause any trouble during installation, and unlike the conventional art, it does not come off from the water collector 4 depending on the installation position.

In the above embodiment, the engagement recess 8 is provided all over the inner circumference of the connector 1, but it may also be provided in either the large connection piece 2 or the small connection piece 3. The cross-sectional shape of the connector 1 may be such that the upper engagement piece 13 has an inverted L-shape in cross-section, as shown in FIG. In addition, when connecting the elbow 6 to the water collector 4, first place the elbow 6 in contact with the lower surface of the water collector 4, and then connect the large connecting piece 2 and the small connecting piece 3. The mating protrusion 5 and the engaging piece 7 may be fitted from the outside.

[Effect of idea]

As described above, the present invention forms a ring-shaped connecting tool with a large connecting piece and a small connecting piece, and the connecting tool projects between an engaging protrusion protruding from the outer periphery of the lower end of the water collector and an outer periphery of the upper end of the elbow. The engaging protrusion and the engaging piece were inserted and engaged into the engaging recess installed on the inner surface of the connector, and the water collector and the elbow were connected. It can be connected securely with a fitting, and even if the elbow is rotated after installation, it will not come off unexpectedly from the water collector, and unlike conventional methods, the elbow does not fit into the locking hole of the water collector. There is no need to align the locking pieces, and the workability is also good.
