Description

[Detailed explanation of the idea] The present invention relates to a terry gutter.

Conventionally, joining parts are used to join the troughs to each other, which requires mold equipment for the terry gutters and mold equipment for the joining parts, which not only requires a large amount of capital investment, but also reduces the workability of joining. There were drawbacks such as poor quality and a stepped surface appearing on the exterior.

The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional method, and includes extending a thin male connecting portion that forms a step on the outer surface of the main body at one end of the main body, and forming a locking protrusion on the inner surface of the thin male connecting portion. At the other end, a female connecting portion is provided extending in a direction symmetrical with respect to the main body and the vertical plane, and a hole that can be engaged with the locking projection is formed in this at a position between the ears corresponding to the locking projection. It is an object of the present invention to provide a terry gutter which can improve workability, improve aesthetic appearance, and reduce mold cost compared to conventional structures.

An embodiment of the present invention will be described below with reference to the drawings.

1 to 5, reference numeral 10 denotes the gutter main body, and at one end thereof, a male connection portion 30 of a predetermined width is provided as shown in FIG. 2, extending from one ear portion 20 to the other ear portion 20. A recessed step A is formed on the outer surface of the gutter main body 10 and extends at an oblique angle (angle α=38) in a direction receding from the main body extension direction shown by a solid arrow in the figure. Locking protrusions 31, 31 are provided on the upper edge of the inner side of the male connection portion 30, and locking protrusions 32, 32 are provided on the side of the inner bottom, respectively, protruding symmetrically with respect to the width direction. ing. At the other end of the gutter main body 10, a female connecting portion 40 of a predetermined width as shown in FIG. It extends at an oblique angle (angle α=38) and in a direction symmetrical to the upstream direction of the gutter and the vertical plane. The female connection portion 40 has a forked shape with an insertion groove 41 whose groove depth is the predetermined width of the male connection portion 30 and whose groove width is the wall thickness of the male connection portion 30, and its outer wall 42
has the same wall thickness as the step depth of the male connection allowance 30. The inner wall 43 of the female connection portion 40 has holes 44, 44 in which the locking protrusions 31, 31 can engage, respectively.
is formed, and locking protrusions 32, 32 are formed on the bottom.
Holes 45, 45 that can be engaged with are provided therethrough.

When installing two terry gutters as a set on a terry roof as shown in Figure 4, one terry gutter 1
For example, the fifth
From the position indicated by the chain line in the figure, the other terry gutter 10
Cut from a predetermined length position (indicated by a chain line in the same figure) from the female connection allowance 40 side of the connector to make both the same length,
The male connecting portion 30 of the other terry gutter 50 is inserted into the insertion groove 41 of the female connecting portion 40 of the one terry gutter 50,
The holes 44, 44 have the locking protrusions 31, 31, the holes 45,
45 until the locking protrusions 32, 32 are engaged with each other. The cut end sides of both terry gutters are connected to the eave gutter as in the conventional case.

Before joining this terry gutter, an adhesive is applied to the male connection portion 30, but since the terry gutter is locked to each other by the protrusions, there is no need to hold the terry gutter until the adhesive hardens, and the execution time is reduced. can be short.

As described above, according to the present invention, since the male and female connection sections are integrally extended at both ends of the gutter body, there is no need for joining parts and there is no need to install a mold for joining parts. First, since it is only necessary to butt connect two gutter members manufactured using one mold, the mold cost can be reduced compared to the conventional method.
Since the gutters are connected by directly inserting and fitting each other, there is no step in the appearance, and since the protrusions are locked, the connection can be made without slippage, making the appearance more beautiful than before. In addition, the joining work can be done easily and in a short time.
