Abstract

PURPOSE:To prevent a clearance in which a shadow is visible from being created in the inside of a joint main body by forming a groove section at a position which is fully in the inside from an end of the joint main body and fitting and providing a water cut-off member which adheres on an outer face of a gutter along eaves. CONSTITUTION:A groove section 11, 11 is formed on an inner face at a position which is fully in the inside from an end of a joint main body 1 which is injection-molded by resin material such as vinyl chloride resin. Also, a tapered face 12, 12 which becomes thin-walled section gradually as an end section approaches an end is formed on an outer face of the joint main body 1. Next, a water cut-off member 2, 2 formed by elastic material such as rubber is fitted into the groove section 11 of the joint main body 1. A plurality of protruding edges 21, 21 are provided on a surface of the water cut-off member 2 in such a manner that they protrude in the inner side of the joint main body 1. When an end section of a gutter N along eaves is fitted into the inner side of the joint main body 1, the protruding edges 21 of the water cut-off member 2 adhere on an outer face of the gutter N in the condition in which they are deformed elastically to cut off water between them, and a clearance in which a shadow is visible is not created on the inner side of the end section of the joint main body 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eaves joint used for connecting eaves gutters.

[0002]

2. Description of the Related Art Eaves gutter joints are always used at eaves gutter connections. In some eaves gutter joints, eaves gutters are attached by fitting without using an adhesive. In this type of eaves gutter joint, for example, as shown in FIG. 4, a step portion 101, which is one step lower than the other portions, is formed on the inner surface of the end portion of the joint main body 100, and along the step portion 101. When the end of the eaves trough N is fitted inside the joint body 100, the water stoppage material 200 comes into close contact with the eaves trough N and the water is stopped between them. (For details, see Japanese Utility Model Publication No. 5-3617 and Japanese Patent Publication No.
-20465 gazette).

[0003]

However, in such a conventional eaves gutter joint, when the end of the eaves gutter N is fitted inside the joint body 100, the end of the step 101 is Since a gap S having a size substantially equal to the wall thickness of the water blocking material 200 is formed inside, a shadow can be seen from the gap S as shown in FIG. 5, which deteriorates the appearance.

In the eaves gutter joint of the present invention, attention is paid to the above problems, and when the end of the eaves gutter is fitted inside the joint body, a gap where a shadow is visible inside the end of the joint body. The purpose is not to be able to.

[0005]

In order to achieve the above object, in the eaves gutter joint of the present invention, the inner surface of the joint body is fitted to the inner surface of the joint body at the position where the eave joint is located inside. A means is provided in which a groove is formed in which a waterproof material that is in close contact with the outer surface of the eaves gutter is fitted and installed.

[0006]

In the eaves trough joint of the present invention, when the end of the eaves trough is fitted inside the joint body, the inner surface of the end of the joint body comes close to the outer surface of the end of the eaves trough. . That is, there is no gap inside the end of the joint body where a shadow can be seen.

[0007]

EXAMPLE First, the construction of an eaves trough joint J of this example will be described in detail with reference to FIG. FIG. 1 is a sectional view showing an eaves-and-groove joint of this embodiment.

In the figure, reference numeral 1 denotes a joint body in which side walls 1b, 1b are formed on both sides of a flat bottom wall 1a, and an ear engaging portion 1c is formed at an upper end portion of each side wall 1b. Injection molded from a resin material such as vinyl chloride resin. In addition, the joint body 1 has a groove portion 1 in which a water blocking material 2 is fitted and installed on an inner surface of a position slightly inward from an end portion.
1 is formed. In addition, a tapered surface 12 is formed on the outer surface of the joint body 1 so that the end portion gradually becomes thinner toward the end.

The water blocking member 2 is formed of an elastic body such as rubber. In addition, the surface of the water blocking material 2 has 3
The ridges 21, 21 and 21 of the book are provided in a state of protruding inside the joint body 1, and when the end portion of the eaves gutter is fitted inside the joint body 1, the ridges of the water blocking material 2 are provided. 21 is elastically deformed and is in close contact with the outer surface of the eaves gutter, and water is stopped between them. The water blocking material 2 may be adhesively fitted into the groove portion 11 with an adhesive, or may be simultaneously injection-molded inside the joint body 1 when the joint body 1 is injection-molded.

Next, the operation of the embodiment will be described with reference to FIGS. FIG. 2 is a cross-sectional view showing a main part of the eaves trough joint of the embodiment in which the ends of the eaves trough are fitted, and FIG. 3 shows an appearance of the eaves trough joint of the embodiment in which the ends of the eaves trough are fitted. It is a perspective view.

When the end portion of the eaves trough N is fitted inside the joint body 1, the inner surface of the end portion of the joint body 1 comes into close proximity to the outer surface of the end portion of the eaves trough N. The gap formed inside the end of the main body 1 is extremely small.

Further, since the end portion of the joint body 1 is gradually thinned toward the end by the tapered surface 12 provided on the outer side thereof, the outer surface of the joint body 1 and the outer surface of the eaves gutter N are separated from each other. The step L between them is also extremely small.

That is, in the eaves gutter joint J of this embodiment, there is no gap in which a shadow can be seen inside the end of the joint body 1, and the outer surface of the joint body 1 and the eaves gutter N. The end portion of the eaves gutter N can be fitted so that no noticeable step is formed between the outer surface and the outer surface.

Further, in the eaves gutter joint J of this embodiment,
If the water blocking material 2 is simultaneously injection-molded during the injection molding of the joint body 1, the water blocking material 2 can be formed without using an adhesive.
Since it can be fixed to, the work of fixing the water blocking material 2 can be simplified.

Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific structure is not limited to this embodiment, and there are design changes and the like within a range not departing from the gist of the present invention. Also included in the present invention. For example, the bottom wall of the joint body may be formed with a spout for connection with a downpipe. Moreover, the cross-sectional shape of the water blocking material is also free. However, in order to stabilize the adhesion to the eaves gutter, a shape having an elastic contact portion such as a ridge that comes into close contact with the eaves gutter in an elastically deformed state as shown in the embodiment is preferable.

[0016]

As described above, in the eaves trough joint of the present invention, the eaves trough fitted to the inside of the joint body is fitted to the inner surface of the joint body from the end of the joint body. A groove is formed in which a waterproof material that fits closely with the outer surface is fitted and installed, so when the end of the eaves gutter is fitted inside the joint body, a shadow is visible inside the end of the joint joint. There can be no gaps.

In the eaves gutter joint of the present invention, since the water blocking material is formed during injection molding of the joint body, the water blocking material is fitted into the groove portion of the joint body. There is also an effect that the water blocking material can be fixed to the joint body without using the.
