Description

[Detailed Description of the Invention] The present invention relates to a rain gutter joint, and particularly to a rain gutter joint that allows vertical gutters with a rectangular cross section to be freely connected.

In general, gutter joints that connect an upper gutter and a lower gutter can be used for gutter joints that have the same shape and diameter, or gutter joints that have the same shape and different diameters, depending on the relationship between the upper and lower fitting tubes. Various types of gutter joints and vertical gutter joints with irregular shapes and diameters have been proposed.

However, there is nothing that is fully satisfactory for use in vertical pipes with a rectangular cross section.

That is, depending on the construction location of the square gutter having such a cross-sectional shape, it may be desired to arrange the vertical gutter at a fixed joint position so as to be offset to the left, right, front, or back.

Therefore, in the conventional joint having a simple fitting structure, two types have to be prepared and used properly, and since they are rectangular, it takes time and effort for positioning.

The present invention solves these conventional problems and makes it possible to easily adjust the position of the downpipe in the front, rear, left and right directions at the fixed joint position.

In other words, the gist of the present invention is to provide a rectangular fitting tube with a rectangular cross section into which a rain gutter or the like is fitted, centering on the vertical axis of the joint body, and to mark the length of each side on the outside of each side of the rectangular fitting tube. Auxiliary fitting pieces of equal length are arranged in parallel with each other with a gap corresponding to at least the wall thickness of the rain gutter, etc. to be fitted, and the auxiliary fitting pieces face each other with a rectangular fitting tube in between. These are rain gutter joints characterized in that they are arranged at symmetrical positions with respect to the rectangular fitting tube.

Hereinafter, specific embodiments will be described with reference to the drawings.

Figure 1 is an explanatory diagram showing an example of a drainage system in which a vertical gutter is connected using the present invention, where A is a water collector, B is an upper large-diameter connecting pipe, C is a rain gutter joint of the present invention, and D is the small diameter connecting pipe (vertical pipe) at the bottom.

FIG. 2 shows an embodiment of the present invention, and is a perspective view of the main body viewed from the bottom side.

Reference numeral 1 denotes an upper fitting tube of the main body, and a square fitting tube 2 having a rectangular cross section smaller than the upper fitting tube 1 is provided at the lower end of the upper fitting tube through a connecting portion 5 to form a joint body.

Reference numeral 3 denotes auxiliary fitting pieces arranged parallel to each other on the outside of each side of the rectangular fitting cylinder 2.

As shown in the sectional view in FIG. 3, the length and arrangement of the auxiliary fitting piece 3 are equal to the length of each side of the square fitting tube 2, and are connected to the outer wall surface of the square fitting tube 2. The auxiliary fitting pieces 3 are arranged in parallel with each other with a gap 4 corresponding to the wall thickness of the vertical trough, and face each other with the rectangular fitting cylinder 2 in between. The auxiliary fitting pieces 3 and the square fitting tubes opposite thereto are configured to match the inner diameter of a rectangular gutter with a rectangular cross section. A vertical gutter having a rectangular cross section can be fitted in combination with the auxiliary fitting piece 3, and the connection can be made by shifting the position arbitrarily.

Since the present invention is configured in this way, by selecting the auxiliary fitting piece, the rain gutters can be connected to the left or right, or front to back, as needed, with the rain gutters offset to one another, and the upper rain gutters can be connected to the wall of the building from the upper rain gutters. It can be placed close to the edge or far away.

Moreover, the rectangular fitting tube 2 is fitted inside the vertical pipe to which it is connected,
Since it is fixed with the auxiliary fitting piece 3, there is no fear of water leakage, and the fitting connection is reliably and firmly performed.

In addition, the connection between the vertical gutter joint and the vertical gutter was explained above as an example.
The present invention is not limited to this, and the same effect can be achieved by applying the same structure to the discharge portion of an elbow, a Y-pipe joint, a water collector, etc., which is, of course, included in the present invention.

As mentioned above, the effect of the present invention as a rain gutter joint is extremely large.
