2. Description of the Related Art Conventionally, as an eaves gutter joint for bonding and connecting square eaves gutters, a joint body having a substantially U-shaped cross section and a holding spatula having a substantially U-shaped cross section along the inner periphery of the joint body. It is known that an eaves gutter insertion gap having a substantially U-shaped cross section is formed between the joint body and the holding spatula (see, for example, FIG. 4 of Japanese Utility Model Laid-Open No. 62-22231). ).

In the case of this eaves gutter joint, an inwardly-opening U-shaped cross section is provided at the upper end of both side walls of the joint body over its entire length. When fitting the end of the eaves gutter from above, the lugs of the eaves gutter caught on the lugs of the joint body, and the end of the eaves gutter could not be inserted into the eaves gutter insertion gap. There was a problem that the connection work with the computer could not be performed smoothly.

As an eaves gutter joint for solving such a problem, for example, in Japanese Utility Model Laid-Open No. 5-96256, as shown in FIG. 4, an outer wall 101 having a substantially U-shaped cross section and a wide width is used.
By connecting the inner wall 102 having a small width to the inner wall 102 via the intermediate connecting portion 103, the outer walls 1 on both lateral sides of the intermediate connecting portion 103 are connected.
01 and the inner wall 102, a concave space 104 into which the end of the eaves gutter is inserted is formed.
And an ear holding portion 106 are disclosed.

In the eaves gutter joint shown in FIG.
Reference numeral 06 protrudes inward only from the center of the upper end of both side walls of the outer wall 101, and the width of the ear holding portion 106 is substantially equal to that of the inner wall 102. When fitting into both ends of the joint from above, the ears of the eaves gutter can be prevented from being caught by the ear holding portions 106 to some extent.

[0006]

However, the installation of the eaves gutter is an operation at a high place, and the operator cannot look into the eaves gutter joint from above. Even with the eaves gutter joints, the eaves gutter ears may run over the ear retainers, and the eaves gutter connection work could not be performed smoothly.

An object of the present invention is to provide an eaves gutter joint that can smoothly connect an eaves gutter even when the lugs of the eaves gutter ride on the lugs of the joint body when connecting to the eaves gutter. It is.

[0008]

According to a first aspect of the present invention, there is provided a gutter-shaped joint main body and a presser piece provided along an inner periphery of the joint main body. An eaves gutter joint is formed between the eaves gutter joint, in which ear holding pieces having a width substantially equal to that of the holding pieces protrude inward from the center of the upper end of both side walls of the joint body. A riding-up prevention piece is provided upright on the upper surface of the ear pressing piece on the rear side wall of the joint body.

(Effect) In the eaves gutter joint according to the first aspect of the present invention, the gutter-like joint main body is provided with a lug piece projecting inward from the center of the upper end on the rear wall side of the main body. Since the riding-up preventing piece is erected on the upper surface, and the width of the ear pressing piece is substantially equal to the width of the pressing piece provided along the inner periphery of the gutter-shaped joint main body, the eaves of the present invention When the eaves gutters are connected to each other using the gutter joints, even if the ears of the eaves gutter ride on the ear-holding pieces, they will slide down in the direction away from the ear-holding pieces along the run-off preventing pieces. For this reason, the connection work of the eaves gutter can be performed smoothly.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an example of an eaves gutter joint of the present invention, and FIG. 2 is an explanatory diagram showing a use state of the eaves gutter joint of FIG.

In FIG. 1, A is an eaves gutter joint made of a vinyl chloride resin, and is composed of a joint body 1 having a U-shaped cross section and a holding piece 2 having a U-shaped cross section. At the upper ends of the front side wall 11 and the rear side wall 12 of the joint body 1, gutter ear receiving portions 13 and 14 each having an L-shaped cross section are provided.

The holding piece 2 is connected to the joint body 1 by a ridge 3 projecting upward along the center inner periphery of the joint body 1. As a result, an eaves gutter insertion gap 4 having a U-shaped cross section is formed between the outer peripheral surface of the holding piece 2 and the inner peripheral surface of the joint body 1. This insertion gap 4 is made substantially equal to the wall thickness of the eaves gutter to be connected. The holding piece 2 is located at the bottom 1 of the joint body 1.
A part of it is cut off at the center.

Ear holding pieces 131 and 141 are integrally formed to project inward from the center of the upper end of the front and rear side walls 11 and 12 of the joint body 1. The width of the binaural pressing pieces 131 and 141 is slightly wider than the width of the pressing piece 2. On both sides of the upper surface of the ear pressing piece 141 on the rear side wall 12, two riding-up preventing pieces 142, 142 are integrally provided upright. As shown in FIGS. 1 and 2, the riding-up preventing piece 142 is a quarter-circular plate-shaped one, and its upper surface is inclined in an arc shape toward both ends of the ear-holding piece 141.
In addition, a locking piece extends from the lower end surface of the binaural pressing pieces 131 and 141.

Next, a method of connecting the eaves gutter joint A and the eaves gutter will be described. As shown in FIGS. 2 and 3, when the end of the eaves gutter 5 is fitted into the end of the joint main body 1 from above, the ears 51 of the eaves gutter 5 are held down by the ear retainers on the rear wall 12 side of the joint main body 1. The upper surface of the piece 142, that is, the riding prevention piece 142
Even if it comes into contact with and is caught, since the upper surface of the ear holding piece 141 is inclined downward in an arc toward the eaves gutter 5 side,
The lower surface of the ear portion 51 of the eaves gutter 5 slides down the arc-shaped upper surface of the ear holding piece 141, and the lower surface of both ears 51 of the eaves gutter 5 is the gutter ear receiving portion 1.
3 and 14.

In this case, since the width of the both ear pressing pieces 131 and 141 of the joint body 1 is slightly wider than the width of the pressing piece 2, the lower surface of the both ear portions 51 of the eaves gutter 5 is a gutter ear support. When the eaves gutter 5 is placed on the portions 13 and 14, the end face of the eaves gutter 5 is located slightly forward of the tip of the holding piece 2. For this reason, the end of the eaves gutter 5 can be smoothly inserted into the eaves gutter insertion gap 4 by pushing the eaves gutter 5 deep into the joint body 1. At this time, both ears 51 of the eaves gutter 5 are also locked by the both ear holding pieces 131 and 141 at the same time. Thus, the connection between the eaves gutter joint A and the eaves gutter 5 is completed. When connecting, the joint body 1
An adhesive is applied to the inner peripheral surface of the end portion of.

In the above embodiment, the rear wall 12 of the joint body 1 is provided.
Riding prevention piece 14 only on the upper surface of the side ear holding piece 141.
Although 2 is provided, a similar riding prevention piece may be provided on the upper surface of the ear pressing piece 131 on the front side wall 11 side. Also, two ear holding pieces 14 are separately provided on both sides of the upper surface of the ear holding piece 141.
Although one is provided, the both ear holding pieces may be integrated. Further, the upper surface of the ear holding piece 141 may be a simple inclined surface.

[0017]

In the eaves gutter joint according to the first aspect of the present invention, the gutter-like joint main body is provided with a lug piece projecting inward from the center of the upper end on the rear side wall side, and the upper surface of the lug piece is provided. The eaves gutter according to the present invention is provided with an eaves gutter according to the present invention because the lugs are set up substantially at the same width as the gutter-like joints provided along the inner periphery of the gutter-shaped joint body. When the eaves gutters are connected to each other using the joint, even if the ears of the eaves gutter ride on the ear holding pieces, they will slide down in the direction away from the ear holding pieces along the riding-up prevention pieces.
