Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an eaves gutter connecting device in which ends of eaves gutters are connected by joints.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 4, an eaves gutter connecting device is known in which an outer joint (b) is fitted on the outer side between the ends of both eaves gutters (a) to be phase-connected. In the eaves trough connection device, the eaves trough (a) and the outer joint (b) are formed in a semi-circular gutter shape, and the outer joint (b) is fitted on the outer side of the eaves trough (a), The ends of the eaves gutter (a) can be easily connected to each other.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional technique, the outer joint (b) is largely exposed on the outside of the eaves gutter (a), and the appearance is not good.

Then, as shown in FIG. 5, it suffices to fit and connect the inner joint (c) inside the ends of the two eaves gutters (a) to be phase-connected. In the eaves trough connection device, the engaging portions (d) formed on both upper ends of the inner joint (c) are respectively locked to the ears (e) formed on both upper ends of the eaves trough (a). The inner joint (c) is then fitted inside the eaves gutter (a). However, in this case, especially when the eaves gutter (a) and the inner joint (c) are formed in a square gutter shape, the bottom part of the inner joint (c) rises and the outer surface of the bottom part and the eaves gutter (a). A gap (f) was likely to occur between the inner bottom surface of the and.

The present invention has been devised to solve the above-mentioned problems in the prior art, that is, the problem is that the inner joints are connected to each other and the inner joints are not exposed to the outside of the eaves gutter. To provide an eaves trough connection device that is good, and in which the bottom of the inner joint and the bottom of the eaves gutter are joined together so that no gap is created between them, and the ends of the eaves gutter are reliably connected to each other. Is.

[0006]

[Means for Solving the Problems]

 The eaves trough connection device of the present invention has a longitudinal ridge formed on the inner bottom surface of the eaves trough, and a groove corresponding to the ridge is formed on the outer bottom surface of the inner joint formed along the inner circumference of the eaves trough. The inner joint is fitted between the ends of both eaves gutters to be formed and connected to each other, and the concave groove is locked to the ridge. This configuration solves the above problem.

[0007]

[Action]

 In the eaves trough connection device of the present invention, since the inner joint is connected by being fitted inside the ends of both eaves troughs to be connected to each other, the inner joint is not exposed to the outside of the eaves trough and is not exposed. In addition, in this case, since the concave groove formed on the outer bottom surface of the inner joint is locked and fitted to the ridge formed on the inner bottom surface of the eaves trough, the bottom part of the eaves trough is fitted. The bottom of the inner joint and the bottom of the inner joint are locked together so that a gap between them is unlikely to occur, and the ends of the eaves gutter are reliably connected by the inner joint.

【Example】

 The eaves gutter connection device shown in FIGS. 1 and 2 is an embodiment of the present invention, in which a longitudinal ridge 2 is formed on the inner bottom surface of the eaves gutter 1 to form a shape along the inner circumference of the eaves gutter 1. A concave groove 4 corresponding to the above-mentioned convex stripe 2 is formed on the outer bottom surface of the inner joint 3 of FIG. It is locked to the ridge 2.

The eaves gutter 1 is in the shape of a square gutter, and is composed of both side wall portions 5 and a bottom portion 6 connecting the both side wall portions 5, and is integrally extruded from synthetic resin. Hollow-shaped ears 7 are integrally formed at the upper ends of both side wall parts 5, respectively, and a ridge 2 having a substantially T-shaped cross section over the entire length in the longitudinal direction is integrally formed at the center of the bottom part 6. Has been projected.

The inner joint 3 has the same angle gutter shape along the inner circumference of the eaves gutter 1 and is composed of front and rear vertical piece portions 8 and a bottom piece portion 9 connecting the vertical piece portions 8 to each other. It was integrally injection-molded at. Further, the upper end portions of both the vertical piece portions 8 are integrally formed with engaging portions 10 which are folded back outward, and the dovetail-shaped concave groove 4 is integrally formed at the center of the bottom piece portion 9. Is formed in

In the eaves trough connection device, both engaging portions 10 of the inner joint 3 are locked to both ears 7 of the eaves trough 1, and the bottom portions of the eaves trough 1 and the inner joint 3 are mutually connected. In the meantime, the concave groove 4 is slidably fitted and locked to the convex strip 2 in the longitudinal direction, and the inner joint 3 is fitted inside the eaves gutter 1.

Therefore, in the eaves gutter connecting device of the embodiment, since the inner joint 3 is fitted and connected inside the ends of both eaves gutters 1 to be phase-connected, the inner joint 3 is connected to the eaves gutter 1. It is not exposed to the outside of the gutter 1 and has a good appearance. In addition, since the groove 2 formed in the center of the outer bottom surface bottom piece 9 of the inner joint 3 is locked and fitted to the ridge 2 formed in the center of the inner bottom surface 6 of the eaves trough 1, the eaves trough 1 The bottom portion 6 of the inner joint 3 and the bottom piece 9 of the inner joint 3 are engaged with each other so that a gap is unlikely to be generated therebetween, and the ends of the eaves gutter 1 are reliably connected by the inner joint 3.

The eaves gutter connection device of the present invention may be as in the embodiment shown in FIG. That is, in the eaves trough connection device of the embodiment, the eaves trough 1 and the inner joint 3 are in the shape of a semi-circle gutter, and the convex ridges 2 and the concave grooves 4 are formed on the bottom so as to correspond to each other. Further, the ridge 2 and the groove 4 are fitted and locked to each other in the facing direction. The inner joint 3 is formed by cutting a synthetic resin extruded into a short fixed length.

[0014]

[Effect of the device]

 As described above, in the eaves trough connection device of the present invention, the inner joint is fitted and connected inside the ends of both eaves troughs to be connected to each other, so that the inner joint is exposed to the outside of the eaves trough. It has a good appearance and the convex groove formed on the inner bottom surface of the eaves gutter is engaged with the concave groove formed on the outer bottom surface of the inner joint so that it fits in the bottom part of the eaves gutter. The bottom of the joint is locked and coupled, and a gap is unlikely to occur between the two, and the ends of the eaves gutter are reliably connected by the inner joint.
