[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a downspout connector for connecting downspouts.

[0002]

2. Description of the Related Art Conventionally, as described in, for example, Japanese Utility Model Application Laid-Open No. 3-9344, a downspout connector having an outlet at one end to be fitted with the inner surface of the downspout end is known.

In such a conventional downspout connector,
When joining the spout and the inner surface of the end of the downspout, an adhesive is applied to the surface of the spout at the time of joining, and then the spout is inserted into the end of the downspout.

[0004]

However, in the above-mentioned conventional downspout connector, when the spout with the adhesive applied thereto is inserted into the end of the downspout, the adhesive applied to the surface of the spout is removed. It may be handled by the end of the downspout and protrude from the joint between the spout and the end of the downspout, resulting in poor appearance and insufficient joining strength.

The present invention has been made by focusing on the problems of such conventional downspout fittings. The purpose of the present invention is to solve the conventional problems and to apply the coating to the surface of the outlet. It is an object of the present invention to provide a gutter connection device in which the applied adhesive does not protrude from the joint with the end of the gutter.

[0006]

In order to achieve the above object, a downspout connector according to the present invention is a downpipe connector provided with a spout at at least one end. Is provided, a groove is formed along the circumferential direction on the surface on the end side than the inlet of the inlet, and the inlet and the groove are communicated by a communication path. is there. The present invention solves the above-mentioned problem by such a configuration.

In the present invention, the material of the downspout connector is not particularly limited. For example, in addition to a synthetic resin such as hard vinyl chloride resin, polyethylene, FRP and polycarbonate, a material such as polyphenylene sulfide is used. Metals such as engineering plastics, iron, stainless steel, copper, and aluminum may be used alone, or a hard vinyl chloride resin coating layer may be provided on both sides of a metal core material such as iron. The materials may be used in appropriate combinations.

[0008]

In the downpipe connecting device of the present invention, an inlet for the adhesive is provided on the surface of the outlet, and a groove is formed along the circumferential direction on the surface on the end side of the inlet of the outlet. Since the inlet and the groove are communicated with each other by the communication path, at the time of joining with the downspout, the spout was inserted into the downspout, and the end of the downspout did not cover the inlet but covered the recess. When the adhesive is injected from the injection port in this state, the adhesive reaches the concave groove via the communication path, contacts the inner surface of the end of the downspout, and furthermore, inserts the inlet into the downspout. The adhesive in the groove enters between the surface of the spout and the inner surface of the downspout, and the spout and the downspout are bonded.

In the downspout connector of the present invention, the adhesive in the concave groove comes into contact with the inner surface of the downpipe, and the adhesive applied to the surface of the outlet is handled like the conventional product. The adhesive does not protrude from the joint between the spout and the downspout.

[0010]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing an example of the downspout connector of the present invention,
2 is a plan view of the downspout connector of the present invention shown in FIG. 1, and FIG. 3 is a sectional view taken along line III-III of FIG.

In FIG. 1, reference numeral 1 denotes a downpipe connector of the present invention made of hard vinyl chloride resin, and the downpipe connector 1 has a shape in which a corner portion of a rectangular tube is concavely curved. The lower half of the downspout connector 1 is an outlet 2 and the upper half of the downspout connector 1 is a receptacle 3. The inlet 2 is provided with an adhesive inlet 21, and a groove 22 is formed in the surface of the outlet 2 on the end side of the adhesive inlet 21 along the circumferential direction. 22 is communicated with a communication path 23. In order to form such an adhesive inlet 21 and a communication path 23, a concave communication path 23 communicating with the concave groove 22 is provided on the surface of the insertion port 2, and an adhesive is formed from above the concave communication path 23. Rigid vinyl chloride resin sheet 2 with an agent inlet 21
4 are adhered.

Reference numeral 25 denotes a hanging tube, and a gutter insertion gap 26 is formed between the hanging tube 25 and the surface of the insertion port 2. An end of the gutter is inserted into the gutter insertion gap 26. As a result, the end of the downspout is covered with the hanging tube 25, so that even if the end of the downspout is slightly cut obliquely, it cannot be recognized from the outside.

[Operation of Embodiment] The operation of the downspout connector 1 of the present invention shown in FIGS. 1 to 3 will be described with reference to FIG. FIG. 4 is an enlarged cross-sectional view of a main part showing a mode in which the outlet 2 of the downspout connector 1 of the present invention is connected to the end of the downspout 4, and as shown in FIG. 4 into the end. In this state, the groove 22 of the outlet 2 is covered by the end of the downspout 4, but the inlet 21 is not covered by the end of the downspout 4.

In such a state, as shown in FIG. 4, the extrusion port of the adhesive container 5 is applied to the injection port 21, and the adhesive is injected from the injection port 21. The adhesive injected from the inlet 21 reaches the concave groove 22 via the communication path 23 and
Fill inside. Stop the injection of the adhesive from the inlet 21,
When the spout 2 is further inserted into the downspout 4, the adhesive filled in the groove 22 enters between the surface of the spout 2 and the inner face of the downspout 4, and the pit insertion gap of the spout 2 When the end of the downspout 4 is inserted into 26, the insertion of the spout 2 into the downspout 4 ends.

Although the adhesive filled in the groove 22 comes into contact with the end of the downspout 4, the adhesive is not handled by the end of the downspout 4, so that the connection between the outlet 2 and the downspout 4 is not possible. The adhesive does not protrude from the joint.

Although the embodiment of the present invention has been described with reference to the drawings, the specific configuration of the present invention is not limited to the illustrated embodiment, and design changes within the scope of the present invention may be made. Included in the invention.

For example, in the illustrated embodiment, an outlet is provided on one of the downspout connectors, but an outlet may be provided on both sides.

[0018]

[Effects of the Invention] In the downspout connector of the present invention, the adhesive in the concave groove comes into contact with the inner surface of the downpipe into which the spout is inserted, and the adhesive applied to the surface of the spout like a conventional product. The adhesive does not protrude from the joint between the outlet and the downspout, and the appearance is good and sufficient adhesive strength can be obtained.
