Description

[Detailed explanation of the idea] This invention relates to a drain for eaves gutters.

In the conventional drain, as shown in Fig. 1, dead leaves, etc. 2 that have fallen into the eaves gutter 1 are washed away from the upstream side of the eaves gutter 1 by rainwater during rainfall, and are attached to the net 4 for removing dead leaves in the drain 3, where they are removed. This has the drawback of blocking the drain 3 and reducing the drainage function of the drain 3.

This idea was made to eliminate the drawbacks of the conventional ones mentioned above, and the net for removing dead leaves was made into a rotatable sphere.
By incorporating a reversing impeller gear mechanism into this spherical net so that half of the spherical net protrudes from the bridge surface, dead leaves, etc. are automatically removed by the power of rainwater, ensuring smooth rainwater drainage whenever it rains. The purpose is to provide a drain that can be used.

An embodiment of this invention will be described below with reference to the drawings.

In Figures 2 and 3, 5 is a cylindrical body with a thick wall portion 5 at the upper end.
a, an annular fitting groove 5b of a predetermined depth is formed in this thick portion from the upper end surface, and two diametrically opposed protrusions 6 are provided protruding from the inner surface.

7 is a mounting part, in this case a ring-shaped eave gutter holding plate with a fitting groove 5b
It has an annular locking portion 7a that is fitted and locked into the ring.

Numeral 8 is a spherical net whose approximately half part closes the opening of the cylinder 5.
a support ring 8a housed in the support ring 8a and provided on one axis;
is rotatably supported by fitting it into the protrusion 6.

9 is an impeller housed within the spherical net 8, and both ends of its shaft 9a are rotatably inserted into each of the protrusions 6.

10 is a reversing gear mechanism, and a gear 10a is fixed to a shaft 9a.
, an internal gear 10b fixed inside a spherical net 8, and an intermediate gear 10C, and the intermediate gear 10C is rotatably supported by an auxiliary shaft 11 extending from one protrusion 6.

The drain with the above configuration connects the shaft 9a of the impeller 9 to the eaves gutter 1.
It is fixed to the eaves gutter 1 by inserting the bottom of the eaves gutter 1 between the eaves gutter pressing plate 7 and the cylindrical body 5 in a direction perpendicular to the length direction of the eaves gutter 1.

When rainwater A flows into the drain from the eaves gutter 1 due to rainfall, the inflowing rainwater hits the lower half of the impeller 9 inside the cylinder 5, causing the impeller 9 to rotate in the direction shown by the solid line arrow in FIG. Accordingly, the spherical net 8 rotates in the direction indicated by the dotted arrow in the figure by the action of the reversing gear mechanism 10.

Therefore, the dead leaves, etc. 2 that have been swept away upstream of the eaves gutter of the spherical net 8 are moved to the downstream side of the eaves gutter, as shown in Figure 4 A → B → C, so that the rainwater flows smoothly without being disturbed by the dead leaves, etc. 2. water is drained from the drain.

As described above, according to this invention, the impeller is rotated by rainwater falling from the bridge surface of the eaves gutter, and this rotational force is transmitted to the spherical net whose half protrudes from the bridge surface. Since the dead leaves etc. that have been attached to the rainwater are removed, if there is rainfall exceeding a certain amount, the dead leaves etc. are automatically removed, and good rainwater drainage can be obtained semi-permanently.
