Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gutter joint that is preferably used when connecting an eaves gutter in which a front side wall of the gutter is inclined rearward.

[0002]

[Prior Art]

 Conventionally, when connecting eaves gutters having a substantially U-shaped cross section, gutter joints as shown in FIGS. 10 to 11, for example, have been used.

In this gutter joint, an outer wall 101 having a substantially U-shaped cross section and a wide lateral wall 101 and an inner wall 102 having a narrow lateral width are connected via an intermediate connecting portion 103, so that the outer wall and the inner wall on both sides of the intermediate connecting portion 103 are connected to each other. A recessed hollow portion 104 into which the end portion of the eaves gutter 120 is inserted is formed between and, and ear receiving portions 105 and ear pressing portions 106 are provided on both upper ends of the outer wall 101.

In such a gutter joint, the end portion of the eaves trough 120 having a substantially U-shaped cross section is fitted into the outer wall 101 from above, and the end portion of the eaves trough 120 is formed along the outer wall 101 into the hollow portion 104. By inserting the ear part 121 of the eaves trough into the ear holding part 106 as well as inserting, the eaves gutter connection work can be easily performed.

[0005]

[Problems to be solved by the device]

 However, as shown in FIG. 12, since the front side wall 132 of the gutter connects the eaves gutter 130 having a shape inclined to the rear side, the outer wall 101 and the inner wall 102 of the gutter joint are matched with the shape of the eaves gutter 130. When the front side wall portions 107 and 108 are formed so as to be inclined rearward, there are the following problems.

That is, when the front side wall portion 107 of the joint outer wall 101 is inclined rearward, the distance W 1 between the upper end of the front side wall portion 107 and the upper end of the rear side wall portion 109 is such that the maximum gutter width W 2 of the eaves trough 130. Since it becomes smaller, it becomes impossible to fit the end of the eaves trough 130 into the inside of the outer wall 101 from above, so that the end of the eaves trough 130 is aligned from the side of the outer wall 101 of the gutter joint. Must be fitted inside the outer wall 101 and then inserted into the recess 104. Therefore, it takes a lot of time to align the ends of the eaves trough 130 and fit them into the inside of the joint outer wall 101, and in particular, unevenness is formed on the rear side wall portion 109 of the joint outer wall 101 and the rear side wall of the eaves trough 130. In such a case, it is difficult to perform the alignment, and there was a problem that the connection workability was significantly reduced.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a good connection workability that can easily connect an eaves gutter in which the front side wall of the gutter is inclined rearward. To provide a good gutter joint.

[0008]
