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 publication,
Conventionally, the edges of the drain hole of the eaves gutter are sandwiched between a pair of cylinders with a brim and a threaded part, so it is necessary to screw the cylinders together, and the upper cylinder is connected to the eaves gutter. I had to put my hand in from above and hold it down.

Therefore, if the shape of the eaves gutter is such that the tip of the roof approaches 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 drainage device for the gutter of the present invention aims to solve the above problems by the configuration described in the claims for utility model registration, and a drainage hole is provided at the bottom of the eaves gutter. ,
A male threaded portion is provided on the outer wall surface of the connector, which is formed into a substantially cylindrical shape and has a locking protrusion at its upper end, and a hanging piece is provided downward from the lower end of the connector, and the locking protrusion The male threaded portion of the connector is screwed into the female threaded portion of the drain pipe which is secured to the drain hole edge of the eaves gutter through the hole and has a female threaded portion formed on the inner wall surface, so that the upper end of the drain pipe is connected to the eaves gutter. The drain pipe is connected to the eaves gutter so as to be in contact with the bottom surface of the eaves gutter.

In this invention, eaves gutter means a gutter body with a groove-shaped cross section, and is attached to the eaves of houses, eaves, or small roofs such as carports.
This also includes a gutter such as a feeding gutter if it has a similar shape.

(Function) In the present invention, by screwing the male threaded part of the connector to the female threaded part of the drain pipe, the drain pipe can be installed below the drain hole of the eaves gutter, and at that time, the hanging piece of the connector can be attached to the drain hole. By pressing with your fingers from below,
The drain pipe can be installed by turning screws without having to put hands inside the eaves gutter.

[Embodiments] The present invention will be described in detail below based on representative embodiments shown in the drawings.

FIGS. 1 to 4 show an example of the gutter drainage system of the present invention. Figure 5 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 denotes a drainage pipe, and an outwardly facing flange 2 is formed at the upper end, and a female threaded part 3 is provided on the inner wall surface.

Reference numeral 4 denotes a connector, which is formed into a cylindrical shape, has a male threaded portion 5 on its outer wall surface, and has locking protrusions 6, 6 protruding upward and outward from its upper end. Approximately V at the bottom end
A letter-shaped hanging piece 7 is provided.

The installation procedure of this gutter drainage device will be explained with reference to FIGS. 2 to 4. Drainage holes 8 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 locking protrusions 6, 6 of the connector 4 are inserted from below the drain hole 8, and the locking protrusions 6, 6 are hooked on the edge of the drain hole 8.

Next, the drain pipe 1 is lifted and the male threaded portion 5 is screwed into the female threaded portion 3. At this time, the rotation of the connector 4 is prevented by pressing the hanging piece 7 of the connector 4 with a finger as shown in FIG. Then, the flange 2 of the drain pipe 1 comes into contact with the edge of the drain hole 8 of the eaves gutter C, and is joined using an adhesive to prevent water leakage.

After that, fit the gutter elbow etc. to the drain pipe 1,
Connect downpipe D. Various connection formats can be selected for the gutter elbows and the gutter D, and the gutter D may be simply connected in the vertical direction, or a gutter joint or chain gutter may be connected.

FIG. 6 shows another example of the gutter drainage device of the present invention.
Like the connector 4 in FIG. 1, this connector 4a has a male threaded portion 5a and a locking protrusion 6a, and is provided with a plate-shaped hanging piece 7A at the bottom. The rigidity of the cylindrical portion of the connecting tool 4a increases to prevent deformation.

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 inventive gutter has the structure described above, there is no need to put your hand in from above the eaves gutter to hold down the connector, and you can screw the drain tube under the eaves gutter. The work of turning and installing the drain pipe can be done easily, and work efficiency is greatly improved.
