SUMMARY OF THE INVENTION An eaves trough connection device of the present invention comprises an outer joint formed along the outer peripheral surface of the eaves trough and an inner joint formed along the inner peripheral surface of the eaves trough. In the eaves gutter connection device that is connected so as to be sandwiched from the inside and outside,
Formed on both upper edges of the outer joint body are ear-holding portions that lock the ears of the eaves trough, and the upper edge ears on the rear side of the inner joint body are connected via the rear ears of the eaves trough. Engage with a rear ear holding portion of the outer joint main body, and extend a locking convex piece bent outward to the front upper edge ear of the inner joint main body. It is inserted and locked in the groove formed inside the ear part in the front of the eaves gutter, and the front ear holding part of the outer joint body is fitted to the outside of the front ear part of the eaves gutter. Therefore, the above problem is solved by this configuration.

[0006]

In the eaves gutter connecting device of the present invention, at the rear, the upper edge ears behind the inner joint body hold the rear ears of the outer joint body through the rear ears of the eaves trough. The engaging convex piece bent and extended at the front upper edge ear portion of the inner joint body at the front is inserted into the concave groove formed inside the ear portion of the front of the eaves gutter. Then, the front ear holding part of the outer joint body is fitted to the front outer side of the eaves gutter, so that the locking projection is inserted into the inner groove of the eaves gutter. The ear portion of the eaves gutter is securely held by being stopped, and the ear portion holding portion is easily fitted from the outside to the ear portion held from the inside.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The eaves gutter connecting device shown in FIGS. 1, 2 and 3 is an embodiment of the present invention, and an outer joint 1 formed along the outer peripheral surface of the eaves gutter B and an inner circumference of the eaves gutter B. In the eaves trough connection device in which the eaves trough B is connected so as to be sandwiched from the inside and outside by the inner joint 2 formed along the surface, the ear b of the eaves trough B is provided at both upper edges of the outer joint 1 main body. The ear holding portions 3 and 4 for locking are formed, and the upper edge ears 6 at the rear of the inner joint 2 main body are inserted through the rear ears b of the eaves gutter B at the rear ears of the outer joint 1 main body. The engaging convex piece 51 is extended to the front edge 5 of the inner end of the inner joint 2 body by engaging with the part holding section 4, and the engaging convex piece 51 is attached to the eaves gutter. B
Of the outer joint 1 main body of the outer joint 1 is fitted to the outer side of the front ear b of the eaves trough B by inserting and locking the groove c formed inside the ear b of the front side. It is something that will be tightened.

The eaves trough joint A is formed by the outer joint 1 and the inner joint 2. The outer joint 1 is arranged on the outer circumference of the eaves trough B, and the inner joint 2 is arranged on the inner circumference of the eaves trough B. , Eaves gutter B from outside to outside fitting 1
The eaves gutter joint A is an eaves gutter B so as to be sandwiched by the inner joint 2 and the inner joint 2.
The end portions of are connected to each other.

The outer joint 1 is provided with outer side surface portions 11 and 12 standing above both ends of the outer bottom surface portion 10, and the outer side surface portions 11 and 12 are provided.
At the upper edge of the ears, the ear holding part 3 for locking the ears b of the eaves gutter B,
4 is formed, and the ear part holding part 4 which is the rear side,
The positioning portion 40 is formed. In this embodiment, the ear holding section 4 includes a lower holding section 41 for holding the lower side of the ear section b of the eaves gutter B.
Further, the holding side portion 42 is erected, and notches 44, 44 are formed on both sides of the holding side portion 42, and the eaves trough B ears b are inward from the upper end of the holding side portion 42 in the central portion. A wrapping upper portion 43 for wrapping the upper portion of the is formed.

Inner side surfaces 21 and 22 of the inner joint 2 are erected above both ends of the inner bottom surface 20, and a positioning portion 40 of the outer joint 1 is provided.
At the upper end of the rear side surface portion 22 located at
A locking portion 60 that engages with 40 is formed. The locking portion 60
The upper wrapping portions 61, 61 for wrapping the upper surface of the eaves gutter B ear portion b extend outward from the upper end of the side surface portion 22 so as to engage with the cutout portions 44, 44 of the outer joint 1. From the upper holding parts 61, 61,
Hanging parts 62, 62 are formed downward. That is, the upper holding part
A gap 63 formed between 61, 61 and between the hanging pieces 62, 62
The wrapping upper portion 43 of the outer joint 1 is engaged with, and the positioning portion 40 and the locking portion 60 are engaged with each other, as shown in FIG.

Therefore, in the eaves gutter connecting device of the embodiment, the concave groove c formed inside the ear b in front of the eaves gutter B is used.
Since the locking convex piece 51 is inserted and locked to the ear gutter B, the front ear part b of the eaves gutter B is securely held, and the ear part b held from the inner side.
The ear part holding part 3 can be easily fitted to the outside from the outside, and the eaves gutter B can be easily connected from a front lower part at a high place and can be surely connected.

Although the positioning portion 40 and the locking portion 60 are engaged with the notch portion in this embodiment, the inner joint 2 can be arranged at a position substantially in the center of the outer joint 1. It suffices if it is in the engaged state.

When connecting the eaves gutter joint A to the eaves gutter B, an adhesive may be used.

[0014]

As described above, in the eaves gutter connection device of the present invention, since the locking projection is inserted and locked in the groove formed inside the ear part in front of the eaves gutter, the eaves gutter of the eaves gutter is secured. The front ears are securely held, and the ears holding part is easily fitted from the outside to the ears held from the inside, making it easy to connect eaves gutters at high places from the front and bottom. It is possible to ensure reliable connection.
