Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a drain joint for a rain gutter. More specifically, the present invention relates to a drain gutter drain joint that connects eaves gutters to a vertical gutter in order to discharge rainwater from the eaves gutter to the vertical gutter, and is capable of draining a large amount of rainwater.

[Conventional technology]

As a rain gutter drain joint for connecting the eaves gutter and the vertical gutter, as shown in the cross-sectional view in FIG. 4, a joint body having a cylindrical outlet is inserted into a through hole of the eaves gutter, and the tubular outlet is connected. A simple cylindrical drain body is screwed on the outer surface of the so that the drain hole and the flange of the joint body sandwich the through hole part of the eaves gutter, and the drain girder is connected to this drain body. Known from the past.

[Problems to be solved by the device]

In the above conventional drain gutter drain joint, since rainwater in the rain gutter is drained to the vertical gutter only from the tubular outlet of the joint body, the amount of drainage is low, and when the amount of precipitation is high, the rainwater is rained. It had the drawback of overflowing the gutter.

The present invention eliminates the above-mentioned conventional drawbacks,
A drain with a box-shaped part is attached to the through hole of the rain gutter through a sandwiching plate with an inflow port, and rainwater in the rain gutter is both the cylindrical outlet of the joint body and the inflow port of the sandwiching plate. (EN) A drain gutter drain joint in which rainwater does not overflow from a gutter even when a large amount of rainfall is provided by being configured to be drained from the gutter.

[Means for Solving the Problems]

The rain gutter drain joint of the present invention comprises a joint body, a sandwich plate, and a drain body. The joint body has a collar projecting from the outside of the cylindrical drop opening, a through hole is formed above the cylindrical drop opening, and a male screw portion is provided on the lower outer circumference. The sandwiching plate has a mounting hole at a substantially central portion, and an inflow port is formed outside the mounting hole. The drain body has a connection port at the bottom of the box-shaped portion, and a female screw cylinder is provided in the box-shaped portion. Then, the sandwich plate is brought into contact with the upper surface of the through hole of the rain gutter, and the drain body is brought into contact with the lower surface thereof, and the lower portion of the cylindrical dropout port of the joint body is attached to the drain body through the attachment hole of the sandwich plate. It is characterized in that it is screwed into a female screw cylinder and a vertical gutter is connected to the connection port of the drain body.

[Function of device]

When the eaves gutter and the gutter are connected by the drain gutter drain joint of the present invention, rainwater in the eaves gutter flows into the drain body from both the tubular outlet of the joint body and the inlet of the clamping plate, and the gutter is And then drained. That is, the drainage of rainwater increases.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the attached FIGS.

1 is an exploded perspective view, FIG. 2 is a cross-sectional view in the lateral direction in the connected state, and FIG. 3 is a cross-sectional view in the longitudinal direction in the connected state.

As shown in FIG. 1, the rain gutter drain joint of the present invention comprises a joint body 1, a sandwiching plate 2 and a drain body 3, which are made of synthetic resin such as vinyl chloride or other materials. There is. The joint body 1 attaches the sandwiching plate 2 and the drain body 3 to the through hole 5 of the bottom portion 41 of the eaves gutter 4 and guides rainwater to the drain body 3, and has a round-shaped cylindrical outlet 11. The tubular outlet
A brim 12 is provided so as to protrude from the center of the outer side of 11. A disk-shaped collar is illustrated as the collar 12, but the collar 12 is not limited to this and may be, for example, a large number of feather-shaped collars. Also, the cylindrical outlet
A through hole 13 is bored above 11 and a male screw portion 14 is provided on the lower outer periphery so that this male screw portion 14 can be screwed into a female screw cylinder 34 of the drain body 3 described later. It has become. Further, a concave groove 15 is formed on the outer periphery of the cylindrical drop opening 11 just below the collar 12, and a projection piece 23 of a sandwiching plate 2 described later is fitted into the concave groove 15. Is illustrated. This is preferable because the joint body 1 and the sandwiching plate 2 can be attached more firmly. The sandwiching plate 2 has an outer shape larger than the through hole 5 of the eaves gutter 4, has a mounting hole 21 substantially in the center thereof, and an inwardly projecting piece 23 is provided at a position facing the mounting hole 21. . An inflow port 22 is formed outside the mounting hole 21. This inflow port 22 is located at a position substantially corresponding to the through hole 5 of the eaves gutter 4, and two inflow ports 22 are provided on both outer sides of the mounting hole 21. The drain body 3 has a horizontally long box-shaped portion 31 having substantially the same diameter as the through hole 5 of the eaves gutter 4, and a bottom 32 thereof is provided with a connection port 33 for connecting the vertical gutter 6. A female screw cylinder 34 is provided in the center of the inside of the box-shaped portion 31.
The lower portion of the cylindrical dropout port 11 of the joint body 1 can be screwed into the 34. When connecting the eaves gutter 4 and the vertical gutter 6, as shown in FIGS. 2 and 3, the sandwiching plate 2 is brought into contact with the through hole 5 of the eaves gutter 4 from the upper surface, and The box-shaped portion 31 of the drain body 3 is brought into contact with the lower surface of the drain body 5. Then
The lower portion of the tubular outlet 11 of the joint body 1 is attached to the mounting hole 21 of the sandwich plate 2.
, The joint plate 1 is rotated to screw the lower portion of the tubular drop opening 11 into the female screw cylinder 34 of the drain body 3 through the mounting hole 21 of the sandwiching plate 2. Alternatively, the lower portion of the cylindrical dropout port 11 of the joint body 1 may be forcibly fitted or screwed in advance into the mounting hole 21 of the sandwich plate 2 so that the projecting piece 23 of the sandwich plate 2 is inserted into the groove 15 of the joint body 1. Alternatively, the lower portion of the cylindrical dropout port 11 of the joint body 1 may be screwed into the female screw cylinder 34 of the drain body 3 after being loosely fitted. Then, the mounting hole 21 portion of the sandwiching plate 2 is sandwiched between the flange 12 of the joint body 1 and the female screw cylinder 34 of the drain body 3, and the peripheral edge portion of the sandwiching plate 2 and the drain body 3 are sandwiched. With the box-shaped portion 31 of the eaves trough 4, the bottom edge of the through hole 5 of the eaves gutter 4 is clamped, and the sandwiching plate 2, the drain body 3, and the joint body 1 are attached to the through hole 5 of the eaves trough 4. To be Then, the vertical gutter 6 is fitted into the connection port 33 of the drain body 3 by using an adhesive or the like, and the drain gutter 6 is connected thereto. When the eaves gutter 4 and the down gutter 6 are connected in this way, rainwater in the eaves gutter 4 flows from the through hole 13 of the joint body 1 through the cylindrical drop opening 11 into the drain body 3, and also the sandwich body It also flows into the drain body 3 from the inlet 22 of the landing plate 2, and is drained through the vertical gutter 6.

[Effect of device]

As described above, according to the present invention, rainwater in the eaves gutter flows into the drain body from both the tubular outlet of the joint body and the inlet of the sandwich plate, and the drainage amount increases, so that even when there is a large amount of precipitation. There is no worry of rainwater overflowing from the eaves. Further, since the sandwiching plate and the drain body are attached so as to sandwich the through hole portion of the eaves trough, the eaves trough and the downspout can be connected easily and reliably.
