Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a downspout joint for rotatably connecting a downspout having a non-circular cross section such as a polygon or an ellipse.

[0002]

2. Description of the Related Art Conventionally, as a downspout joint capable of rotatably connecting a downspout having a non-circular cross section such as a polygonal shape or an elliptical shape, it has been described in design gazette No. 782829. Something like that is known.

This vertical trough joint has a circular outlet formed at one end, an upper member having a non-circular connecting portion formed at the other end, and a circular receiving port formed at one end, and also has a non-circular shape. A lower member having a connecting portion formed at the other end, wherein the circular insertion opening of the upper member and the circular receiving opening of the lower member are rotatably fitted to each other. The non-circular connection part has a side surface parallel to the rainwater inflow direction and a bottom surface perpendicular to the side surface.

[0004]

However, in such a conventional downspout joint as described above, since the non-circular connection portion of the upper member has the bottom surface perpendicular to the rainwater inflow direction. , Rainwater flowing from the downpipe connected to the non-circular connection part of the upper member hits the bottom of the non-circular connection part and jumps straight up, causing a swirl. At times, there was a problem that rainwater leaked from the connection between the non-circular connection portion of the upper member and the vertical gutter, or rainwater leaked back and overflowed from the eaves gutter.

In view of the above problems, the present invention can connect a vertical gutter having a non-circular cross section so that the vertical gutter can freely rotate, and rainwater flowing from the vertical gutter can be smoothly rotated without causing swirling. The aim is to provide a downspout fitting that runs down to.

[0006]

In order to achieve the above object, a vertical joint of the present invention has a circular spout at one end and a non-circular connecting portion at the other end. A lower member having a circular receiving opening formed at one end and a non-circular connecting portion formed at the other end, and the circular receiving opening of the upper member and the circular receiving opening of the lower member. In a downspout joint that is rotatably fitted to each other,
Inside the non-circular connection portion of the upper member, an inner wall is provided with a gap for inserting a gutter, and the inner surface of the inner wall is a circular shape of the inner face of the gutter inserted into the gap for inserting the gutter and the circular shape of the upper member. The inner surface of the spigot is configured to be smoothly continuous.

[0007]

In the vertical gutter joint of the present invention, when the vertical gutter is inserted into the vertical gutter insertion gap of the upper member, the connecting portion between the non-circular connecting portion of the upper member and the vertical gutter becomes the non-circular connection of the upper member. It is sealed by an inner wall provided inside the portion, and the inner surface of the downspout and the inner surface of the circular outlet of the upper member are smoothly continuous through the inner wall. Therefore, the rainwater flowing from the vertical gutter inserted in the vertical gutter insertion gap of the upper member smoothly flows down along the inner surface of the inner wall provided in the upper member, and the vertical gutter connected to the non-circular connection part of the lower member. Flow into.

EXAMPLE First, the construction of a vertical gutter joint J will be described with reference to FIGS. 1 and 2. 1 is an exploded perspective view showing a vertical joint of this embodiment, and FIG. 2 is a sectional view taken along line II-II of FIG.
In the figure, 1 is an upper member and 2 is a lower member.

The upper member 1 has a non-circular connecting portion 11 at one end.
And a circular outlet 12 is formed at the other end. The non-circular connecting portion 11 is formed into a shamisen-like shape by flatly crushing two opposing positions of a circular pipe, and a ridge formed on the outer surface of the vertical gutter T1 is fitted to the central portion of the circular portion. A mating fitting portion 111 is provided. The circular outlet 12 is formed in a circular shape having a size close to an inscribed circle of the non-circular connecting portion 11, and a ridge 12 is formed on the outer circumference.
1 is continuously formed over the entire circumference.

The upper member 1 has a non-circular connecting portion 11
An inner wall 14 is provided on the inner side of the inner wall 14 with a gap 13 for inserting a gutter, and the inner surface of the inner wall 14 is a circular shape of the inner surface of the gutter T1 inserted into the gap 13 for inserting a gutter and the upper member 1. The curved surface is formed so as to be smoothly continuous with the inner surface of the outlet 12.

The lower member 2 has a non-circular connecting portion 21 at one end.
Is provided, and a circular receiving port 22 is formed at the other end. The non-circular connecting portion 21 is formed in the same cross-sectional shape as the non-circular connecting portion 11 of the upper member 1,
The circular receptacle 22 is the circular receptacle 12 of the upper member 1.
It is formed in a slightly larger circular shape. Reference numeral 211 in the drawing denotes a fitting portion that fits with a ridge formed on the outer surface of the vertical gutter.

The lower member 2 has a circular receiving opening 22 rotatably fitted in the circular insertion opening 12 of the upper member 1, and the circular receiving opening 22 is locked to the ridge 121 of the upper member 1. As a result, movement in the exit direction is also restricted.

Next, the operation of the embodiment will be described.

In the vertical trough joint J of this embodiment, since the circular insertion port 12 of the upper member 1 and the circular receiving port 22 of the lower member 2 are rotatably fitted, as shown in FIG. The vertical gutter T1 is connected to the non-circular connecting portion 11 of the member 1, and the lower member 2
When the vertical gutter T2 is connected to the non-circular connection part 21 of FIG. 1, the upper vertical gutter T1 and the lower vertical gutter T2 can be twisted. That is, as shown in FIG. 4, if the vertical gutter joint J of this embodiment is used below the elbow E that connects the horizontal gutter Y and the vertical gutter T1, the lower gutter Y is fixed while the lower gutter T2 is fixed. The orientation of can be freely changed on the horizontal plane by 360 degrees.

By the way, when connecting the vertical gutter T1 to the non-circular connection portion 11 of the upper member 1, the vertical gutter T1 is inserted into the vertical gutter insertion gap 13 of the upper member 1. Then, the connecting portion between the non-circular connecting portion 11 of the upper member 1 and the vertical gutter T1 is
Is sealed by an inner wall 14 provided inside the non-circular connecting portion 11, and the inner surface of the downpipe T1 and the inner surface of the circular outlet 12 of the upper member 1 are smoothly continuous with each other through the inner wall 14. Therefore, the rainwater flowing from the trough T1 inserted into the trough insertion gap 13 of the upper member 1 smoothly flows down along the inner surface of the inner wall 14 provided in the upper member 1, and the non-circular connection of the lower member 2 is made. It flows into the vertical gutter T2 connected to the portion 21.

In other words, the waterproofness between the non-circular connection portion 11 of the upper member 1 and the vertical gutter T1 is increased, and rainwater smoothly flows down the inside of the vertical gutter joint J so that the swirl occurs inside the vertical gutter joint J. As a result, even if the amount of rainfall is large, rainwater leaks from the connection between the non-circular connection portion 11 of the upper member 1 and the vertical gutter T1, or rainwater flows backward and overflows from the eaves gutter. It will not happen.

5 and 6 are cross-sectional views showing modified examples of the upper member. That is, as the upper member 1, as shown in FIG. 5, the inner wall 14a may be molded separately, and the upper member 1a fixed with an adhesive or the like may be used instead.
As shown in, the upper member 1b in which the inner wall 14b is formed in a hollow shape with a wall having a uniform thickness may be used instead.

Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific structure is not limited to this embodiment, and there are design changes and the like within a range not departing from the gist of the present invention. Also included in the present invention. For example, in the embodiment, the vertical gutter joint in which the upper member and the lower member are formed in a socket shape is shown, but one of the upper member and the lower member may be formed in an elbow shape. Further, the upper member and the lower member may be formed in an arc shape having substantially the same curvature, and the circular insertion opening of the upper member and the circular receiving opening of the lower member may be fitted so as to be rotatable and axially slidable. Further, in the embodiment, the vertical gutter joint in which the inner surface of the inner wall provided in the upper member is formed into a curved surface is shown.
The inner surface of the inner wall may be formed as an inclined surface as long as the inner surface of the vertical gutter inserted into the vertical gutter insertion gap and the inner surface of the circular opening of the upper member are smoothly continuous.

[0019]

As described above, in the vertical joint of the present invention, the inner wall is provided inside the non-circular connection portion of the upper member with a space for inserting the vertical gutter, and the inner surface of the inner wall. However, since it is formed in such a shape that the inner surface of the trough inserted in the gap for inserting the trough and the inner surface of the circular outlet of the upper member are smoothly continuous, the non-circular connection portion of the upper member and the trough It is possible to increase the water stoppage between the rainwater and the rainwater so that the rainwater smoothly flows down inside the downspout joint without causing swirling. As a result, even if the amount of rainfall is large, rainwater will not leak from the connection between the non-circular connection portion of the upper member and the vertical gutter, and rainwater will not flow backward and overflow from the eaves gutter.
