[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter joint used for connecting eaves gutters in a longitudinal direction.

[0002]

2. Description of the Related Art A gutter joint composed of an outer peripheral body along an outer surface of an eaves gutter and an inner peripheral body along an inner surface and connected by sandwiching the eaves gutter from inside and outside is disclosed in, for example, JP-A-62-276157. As shown, it is known.

It is also known to prevent water leakage by fixing an elastic body such as a sponge to a contact surface of a gutter joint with an eaves gutter, for example, as disclosed in JP-A-53-56720. It is.

[0004]

However, there has been a problem that the elastic body fixed to the contact surface with the eaves gutter tends to peel off from the gutter joint due to expansion and contraction of the eaves gutter.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and to provide a gutter joint which can prevent the elastic body from peeling off from the gutter joint due to body expansion or contraction of the eaves gutter.

[0006]

The gutter joint according to the present invention comprises a first joint and a second joint for holding an eaves gutter from inside and outside, and an elastic body having a concave groove formed on one side is formed by the elastic member. With the groove facing outward in the width direction, the groove is fixed to the outer peripheral wall of the groove-shaped main body of the first joint. A locking means is provided.

The material of the elastic body fixed to the gutter joint of the present invention is not particularly limited, and examples thereof include a closed-cell synthetic resin foam such as cross-linked highly foamed polyethylene. Further, the shape, size, number and the like of the concave grooves are not particularly limited, but it is desirable that the depth is larger than the body expansion size of the eaves gutter.

[0008]

The present invention comprises a first joint and a second joint which sandwich an eaves gutter from inside and outside, and an elastic body having a groove arranged on one side is arranged so that the groove is directed outward in the width direction. Since the fixing means is fixed to the outer peripheral wall of the groove-shaped main body of the first joint, and both ends of the groove-shaped main body are provided with locking means for the edge of the second joint fitted from outside the eaves gutter. The body expansion of the eaves gutter can be absorbed by the concave groove, and the elastic body is prevented from peeling off due to the body expansion and contraction of the eaves gutter.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a first joint constituting an example of the gutter joint of the present invention, and FIG. 2 is a perspective view showing a use state of the gutter joint of the present invention.

In the first joint which constitutes the gutter joint of the present invention shown in FIG.
An elastic body 2 made of a closed-cell polyethylene foam having four square concave grooves 21 having a depth of 1 mm arranged at 9 mm intervals.
Are fixed by an adhesive with the concave groove 21 facing outward in the width direction.

A front flange edge 12 and a rear flange edge 13 extend horizontally at the upper end of the groove-shaped main body 11, and the front flange edge 12 has a front locking ridge 16 at its lower end. A front locking edge 14 is vertically provided, and a rear locking edge 15 having a rear locking ridge 17 at a lower end is vertically provided at a front end of the rear flange edge 13.

In use, as shown in FIG. 2, first, a front ear edge 41 of a second joint 4 constituting a gutter joint is fitted from the outside of the square tubular front edge 31 of the eave gutter 3 and A rear ear edge 42 is fitted from outside the square tubular rear ear edge 32. Then
The front edge 41 of the second joint 4 is connected to the front locking ridge 16 of the first joint 1.
The connection is completed by engaging the rear ear edge 42 with the rear locking ridge 17 of the first joint 1.

[0013]

[Effect of the Invention] Since the present invention is configured as described above, the expansion of the eaves gutter can be absorbed to prevent the elastic body from peeling off from the gutter joint.
