Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a gutter drainage device.

(Conventional technology) Conventionally, in order to drain rainwater from eaves gutters to downpipes,
One is done from the eaves gutter through a water collector, and the other is
There is a system that connects a drain pipe to the drain hole of the eaves gutter, as shown in Publication No. 9488.

(Problems to be Solved by the Invention) The latter drainage system has the advantage of allowing the position of the drainage hole of the eaves gutter to be selected on-site, providing a high degree of freedom in construction.

However, as is clear from the above-mentioned publication, in the past, the edge of the drain hole of the eaves gutter was clamped with a pair of cylindrical bodies each having a flange and a threaded part, so it was necessary to screw the cylindrical bodies together. Therefore, the upper cylinder had to be held in place by inserting a hand from above the eaves gutter.

Therefore, if the shape of the eaves gutter is such that the tip of the roof catches up with you and there is no space to put your hand in, or if the upper part is sealed like a valley gutter, the above construction is impossible or difficult. I was supposed to master it.

(Means for solving the problem) The gutter drainage device of the present invention aims to solve the above problems by the configuration described in the claims for utility model registration. A drainage hole is provided at the bottom of the eaves gutter, a male thread is provided at the lower end of the connector, and a rod-shaped protrusion in the horizontal direction is provided at the upper end of the connector. It is formed slightly larger than the width of the bottom of the eaves gutter so that it can be inserted into the hole from below, the protruding part is housed inside the eaves gutter, and a protruding part is provided in the center from the inner wall of the drain pipe, A female threaded portion is formed at the center axis of the drainage tube of the protruding portion, and the male threaded portion of the connector is screwed into the female threaded portion, so that the drainage can be completed with the upper end of the drainage tube in contact with the bottom surface of the eaves gutter. The tube is connected to the eaves gutter.

In this invention, an eaves gutter means a gutter body with a groove-shaped cross section, and is installed at the eaves of a house, an eave, or a small roof such as a carport, but if it has a similar shape, it can also be used as a feeding gutter. This also includes gutters like this.

(Function) In the present invention, by screwing the male threaded part of the connector into the female threaded part of the protruding part of the drain pipe, the drain pipe can be installed below the drainage hole of the eaves gutter. Rotation is prevented by the overhanging portion coming into contact with the side wall of the eave gutter, and the drain tube can be installed by turning the screw without having to put hands inside the gutter.

Further, a bar-shaped projecting portion in the horizontal direction is provided at the lower end of the connector, and the projecting portion is formed slightly larger than the width of the bottom of the eaves gutter so that the projecting portion can be inserted into the drainage hole from below. Therefore, the shape of the eaves and gutters, etc.
If the tip of the roof is approaching and there is no space to put your hand in, or even if it is sealed like a valley gutter, insert the overhang from below the drainage hole provided at the bottom of the eaves gutter. can do.

(Example) Hereinafter, a detailed description will be given based on a representative example of the present invention shown in the drawings.

FIGS. 1 to 5 show an example of the gutter drainage system of the present invention. Figure 6 shows an example of the usage status of the drainage system using the invented gutter. A drainage system is used. The cross-sectional shape of the eaves gutter C is narrow at the top to prevent rainwater from scattering, making it difficult to reach from above.

FIG. 1 shows the main parts of the gutter drainage system of the present invention. Reference numeral 1 designates a drainage pipe, which has a flange 2 extending outward at its upper end, and a plate-shaped protrusion 3 diametrically extending between the inner walls of its lower end. A columnar body 5 in which a female threaded portion 4 is formed.
has been erected. The female threaded portion 4 is along the central axis of the drain tube 1.

6 is a connector, and a male threaded portion 7 is attached to the lower end of the rod-shaped body.
is formed, and a plate-shaped projecting portion 8 projecting to both sides is provided at the upper end.

The installation procedure of this gutter drainage device will be explained with reference to FIGS. 2 to 5. Drainage holes 9 opened at the construction site are provided at appropriate locations on the eaves gutter C. The eaves gutter C is attached so that the tip of the eaves B is inserted (mounting fittings and the like are omitted). The overhanging part 8 of the connector 6 is placed from below the drain hole 9, and the male threaded part 7 is suspended below.

Next, the female threaded part 4 of the drain tube 1 is lifted up while being placed against the male threaded part 7, and the male threaded part 7 is screwed into the female threaded part 4. At this time, the connector 6
The tip of the overhanging portion 8 is connected to the eaves gutter C as shown in FIG.
The rotation is stopped by coming into contact with the side wall of the Then, the flange 2 of the drain tube 1 comes into contact with the edge of the drain hole 9 of the eaves gutter C, and is bonded using an adhesive to prevent water leakage.

After that, the gutter elbow 10 is fitted into the drain pipe 1, and the gutter D is connected to the gutter elbow 10. Various connection types can be selected for the gutter elbow 10 and the gutter D, and the gutter may be simply connected in the vertical direction, or a gutter joint or a chain gutter may be connected.

FIG. 7 shows another example of the gutter drainage device of the present invention.
A flange 2a is provided at the upper end of the drain pipe 1a, and a protrusion 3a projects from the inner wall at the lower end to the center. A female thread 4a is formed at the tip of the protrusion 3a. A male threaded portion 7a is provided at the lower end of the connector 6a, and the tips of projecting portions 8a extending from the upper end to both sides are slightly bent. This part can also be used in the same way as the part shown in FIG.

Such a gutter drainage device of the present invention can be suitably used not only in the above embodiments but also in valley gutters, entrance porch gutters, and terrace gutters.

(Effects of the invention) Since the drainage device for the gutter of the present invention has the configuration described above, there is no need to put your hand over the eaves gutter to hold down the connector, and the overhanging part is attached to the side wall of the eaves gutter. The abutment prevents rotation, and the drain tube can be screwed under the eaves gutter, making it easy to install the drain tube, greatly improving work efficiency.

Further, a bar-shaped projecting portion in the horizontal direction is provided at the lower end of the connector, and the projecting portion is formed slightly larger than the width of the bottom of the eaves gutter so that the projecting portion can be inserted into the drainage hole from below. Therefore, the shape of the eaves and gutters, etc.
If the tip of the roof is approaching and there is no space to put your hand in, or even if it is sealed like a valley gutter, insert the overhang from below the drainage hole provided at the bottom of the eaves gutter. It has the advantage of being easy to install.
