DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a split water intake joint for installing a rainwater storage tank at an intermediate portion of a downspout to take in rainwater flowing down the downspout and to introduce the rainwater into the storage tank. It is.

[0002]

2. Description of the Related Art Conventionally, many methods have been devised and partially used for collecting rainwater flowing down a downspout and introducing it into a storage tank for the purpose of effectively utilizing the rainwater. (Jpn.
When attaching an intake joint to a downspout already installed in a building, it is not possible to attach the downspout even if the space between the downspouts is cut, while the upper and lower downspouts are fixed. In addition, since the intake joint is manufactured according to the outer diameter of the downspout, it cannot be used except for downspout of the same diameter, which is inconvenient.

[0003]

The above-mentioned conventional water intake joint cannot be used except for a downspout of the same diameter, and when it is attached to an installed downspout, both sides of an intermediate portion of the downspout are cut off, and It has inconvenience that it cannot be attached unless the upper or lower side of the cut surface is moved. Therefore, there has been a demand for a split water intake joint that can be attached while fixing both the upper and lower cut surfaces of the downspout and that can be commonly used for downspouts having different diameters.

[0004]

Means for Solving the Problems Along the inner wall surface of a vertical pipe attached to the middle part of a downspout and having upper and lower ends opened,
In a water intake joint in which an annular guide groove 5 is provided at an angle and an intake port is provided at the lowest position of the guide groove, the water intake joint is vertically divided into two parts, and coupling guide columns 3, 4 are provided at both ends of the outer surface of each divided body. The problem has been solved by providing a split water intake joint in which the two divided bodies are connected by the fixture 10 having the receiving portions of the connecting guide columns of the two divided bodies in parallel.

[0005] At the upper end or lower end of the vertical pipe, a coupling ring attachable to the upper end or lower end of the vertical gutter is detachably provided so that it can be mounted to vertical gutters having different diameters.

[0006]

According to the present invention, the split intake joint can be fitted from the side even when the split intake joint is installed in the middle of the downspout of the downspout already installed in the building, so that the upper and lower downspouts are fixed. It can be installed as it is.

When the split water intake joint is joined to form a single vertical pipe, a rainwater guide groove 5 is formed by a bank 6 provided on the inner surface of the cylindrical body. Rainwater can be taken from here through the water intake 7.

When the same split water intake joint is attached to a downspout having a different diameter, it is possible to cope with a downspout having a different diameter by attaching a coupling ring above or below a cut surface on the downspout side.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A protruding bank 6 is provided along the inner wall surface of a vertical pipe body whose upper and lower ends are opened, and an annular guide groove 5 is provided.
The guide groove is provided at an angle, and constitutes an intake joint to which an intake port is attached at the lowest position. The guide groove is fitted with a projection on one side and a cutout on the other side at the connecting end. The intake joint is divided vertically into two parts, and the connecting guide pillars 3 are provided at both ends of the outer surface of each divided body.
4 is provided. The coupling guide column 3 of one of the divided bodies is L
It is shaped like a letter and has the role of a stopper for the other connecting guide post 4.

In order to integrate the coupling guide columns 3 and 4 of the two divided bodies, a fixing tool 10 having a receiving portion for the coupling guide columns 3 and 4 is inserted into both sides of the divided body from above, and as shown in FIG. Split intake joints can be combined into one vertical tube.

FIG. 6 shows a state in which a space is created by cutting both sides of a portion to be installed with respect to a downspout already installed in a building, and the upper and lower downspouts may be fixed. In order to install the split water intake joint, in the case of a small diameter, the small diameter pit upper ring A is inserted into the upper side 11 of the pit. Next, the one side 1 of the split water intake joint is inserted from the lower side 12 of the downspout and fitted to the upper ring A. Next, the other side 2 of the split intake joint is aligned with the ring A, then lowered, and inserted into the inner surface of the lower downspout. The time when the coupling guide column male 4 side is lowered to the stopper on the coupling guide column female 3 side is when the split intake joint one side 1 and the split intake joint other side 2 are horizontal. Finally, the fixed joint 10 is inserted from both sides of the coupling guide columns 3 and 4 on both sides from the outside, and is fixed to one side 1 of the split water intake joint.

In order to attach the medium diameter downspout shown in FIG. 7, a space is created by cutting both sides of the downspout at the portion to be installed. Insert. Next, the one side 1 of the split water intake joint is connected to the lower diameter ring B
Of the downpipe and align the upper part with the outer surface of the upper part 11 of the downspout. Further, the other side 2 of the split intake joint is aligned with the outer surface of the upper side 11 of the downspout, inserted into the inner side of the lower ring B of the middle diameter downspout, and lowered downward. At this time, when the connecting guide post male 4 side is stopped by the stopper on the connecting guide post female 3 side, the split intake joint one side 1 and the split intake joint other side 2 are joined, and the fixed joint 10 is connected to the joint guide. Fit the pillars 3 and 4 from both sides and fix them.

To attach the large diameter downspout shown in FIG. 8, first cut both sides of the downspout where it is desired to install. Upper side of downspout 1
1. Insert the large-diameter gutter upper ring D into the lower
The large diameter downspout lower ring C is inserted into the pipe. The large-diameter ring D has a small-diameter cylinder at the lower part that fits into the upper part of the split intake joint. Next, one side 1 of the split water intake joint is inserted into the inner surface of the large-diameter downspout lower ring C, and fitted to the outer surface of the large-diameter downspout upper ring D. Next, the other side 2 of the split water intake joint is aligned with the outer surface of the upper ring D of the large diameter pit, and inserted into the inner surface of the large diameter pit ring C. Furthermore, when the connecting guide columns 3 and 4 are horizontal, the fixed joint 10 is inserted into the connecting guide columns 3 and 4 on both sides. Finally, the large-diameter downspout upper ring D is slid down onto the split intake joints 1 and 2.

[0014]

According to the present invention, even for downspouts having different diameters, small, medium and large downspouts can be handled by changing the relay ring with one kind of split intake joint.
