DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A rain gutter litter blocking prevention device of the present invention will be described below with reference to a rain gutter litter blocking prevention device 1 of the first embodiment shown in FIGS. Is
As shown in FIG. 1, in a portion corresponding to the horizontal gutter 2 and the vertical gutter 3, a water passage 2 a is opened, and as shown in FIG.
The downspout 2 is separated from the ends 2b, 2b of the downspout 2
May be connected within

Next, in the embodiment shown in FIGS.
The opening of the water passage 2a of the horizontal gutter 2 is opened to the vertical gutter 3 so as to fit the inner surface of the horizontal gutter 2 and to be in contact with the required length of the horizontal gutter 2 for a required length and to have a required thickness that can be fixed by an appropriate means such as an adhesive material. A base plate 4 having a required width and length is provided by an appropriate material, and a central part of the base plate 4 is fitted with a water outlet 2a of the horizontal gutter 2 and a water outlet 5 into the vertical gutter 3 is provided in the embodiment. In this embodiment, the base plate 4 is provided from a divided water outlet 5a which is elongated in a direction perpendicular to the longitudinal direction of the base plate 4 and is opened at a required interval in the longitudinal direction.

Next, the bottom edge 6a is integrally connected to the upper surface of the base plate 4, and the left and right inclined side edges 6b and 6c are formed as a scoop exclusion surface from an appropriate plate material having a required thickness and a triangular shape as a whole. And a rake-removal rectification plate 6 in which the front and rear surfaces 6d and 6e serve as rectification surfaces.

[0012] The required number of the rake-removing wind-regulating plates 6 are
On the upper surface of the base plate 4, they stand at predetermined intervals corresponding to the water outlets 5 and in the transverse direction to the longitudinal direction of the base plate 4 so as to be integrally aligned and stand up, and each of the standing rake eliminating winds The left and right top end surfaces 6b1 and 6c1 of the left and right inclined side end surfaces 6b and 6c of the exclusion plate 6 are provided with the angled top plate 7 back and forth, and the left and right top end surfaces 6b1 and 6c1 are integrally covered with each other. It is provided with a litter prevention device 1 for rain gutters.

The above is a description of the structure of the rain gutter litter prevention device 1 according to the first embodiment of the present invention, and the present invention is not limited to the structural members and the manufacturing examples. For example, since the entire side shape of the rake elimination and wind elimination plate 6 is formed in a triangular shape, the top shape is a mountain-shaped top plate 7. However, the shape as another embodiment is a trapezoidal shape, and the left and right inclined side end surfaces are required. The shape of the top portion is not limited as long as the end surface is a scooped-up inclined end surface, and other shapes other than the triangle and the trapezoid may be used. Then, the synthetic resin material can be molded by an injection molding machine for each member or the whole member at once. Also, the rake-removing wind-regulating elimination plate 6 may not have a similar shape on the left and right sides.

The constituent members may be made of any synthetic resin, such as the same as the rain gutter, or any other synthetic resin or metal, as long as it is resistant to changes in direct sunlight, wind and rain, and temperature and is easy to process. is there.

If the angle between the side gutter 2 and the left and right inclined side end surfaces 6b and 6c of the scoop elimination and wind elimination plate 6 is too large, the fall of leaves by the wind becomes difficult to fly. Then, the inflow port formed by the left and right inclined side end surfaces 6b and 6c is easily blocked. Also, if the angle of the left and right inclined side end surfaces 6b and 6c is reduced, leaf fall will be somewhat easier to fly, but the inlet formed by the left and right inclined side end surfaces 6b and 6c will be more likely to be closed as described above. (30 ° to 35 ° in the drawing is appropriate)

With respect to the size, the rainfall gutter litter blocking prevention device 1 of the first embodiment shown in the drawings of the present invention is intended for a place where there is a lot of leaves, and in a place where there is a relatively small number of leaves, the height is also small. A small one that fits inside the rain gutter is sufficiently effective.

Since the rainfall gutter litter prevention device 1 according to the first embodiment of the present invention is configured as described above, even if fallen leaves stay in the horizontal gutter 2, it is flat against rainwater. It floats on the upper side along the left and right inclined side end faces 6b and 6c of the rake rejection wind regulating plate 6, and does not block the left and right inclined side end faces 6b and 6c. Also, the base plate 4
For example, when the water outlet 5 is elongated in the transverse direction with respect to the longitudinal direction of the base plate 4 and is divided into a plurality of portions as in the embodiment, the water outlet 5 has a lattice shape and clogs the downspout 3. There is nothing.

Between the plate surfaces of the rake-removing wind-regulating plate 6,
Even when leaves fall, the gap between the plate faces of the rake-removal wind elimination plate 6 is narrow. Then, the left and right inclined side end faces 6 of the rake-removing wind regulating plate 6
b, 6c, so that they do not enter the downspout 3 and even small ones do not enter the downspout 3 because they are obstructed by the inner water outlet 5, so that the downspout 3 is clogged. Since the falling leaves do not pass through, the downspout 3 will not be clogged. The apparatus of the present invention has a structure with good ventilation, and leaves and the like are dried and shrunk and discharged outside by the wind.

Since the space between the rake elimination and wind elimination plates 6 is reduced by the thickness of the rake elimination and air elimination plates 6, the passage becomes a narrow passage to the outside and the passage speed increases from the surroundings. Small pieces such as leaves falling between the wind elimination plates 6 are blown off by the passing wind. Further, in the first embodiment, since the angled top plate 7 is connected and covered on the left and right top end surfaces 6b1 and 6c1 of the rake-removing wind regulating plate 6 laminated at required intervals, air flowing from one side to the other is provided. Rises along one slope of one chevron top plate 7, and on the other side, the other slope descends, so a negative pressure is generated there and air is sucked out on the other side The air flow between the rake-eliminating wind-regulating elimination plate 6 surely increases in speed from the outside, and small pieces or the like staying inside are blown off by the passing wind.

Further, as described above, since the left and right top end surfaces 6b1 and 6c1 of the rake elimination and wind elimination plate 6 are covered with the angled top plate 7, they are directly applied to the part of the rain gutter fall prevention device 1 from outside. Even if fallen leaves or the like fall on the top plate 7, they fall on the mountain-shaped top plate 7, so that they do not get caught between the rake-removing and wind-reducing elimination plates 6, and slide down to the outside, and stay in the part of the litter prevention device 1 for rain gutters. There is nothing to do.

Next, a second embodiment of the present invention will be described with reference to the drawings shown in FIGS. 7 to 10. FIG. This is based on the rain gutter litter blocking prevention device 1 of the first embodiment, and is provided with a wind-cleaning plate 13 which is rotatable by wind power.
This makes it possible to further forcibly remove the fallen leaves and the like that have entered between 6.

In the same manner as in the first embodiment, it has a required thickness which is suitable for the inner surface of the gutter 2 as shown in FIG. A base plate 14 having a required width and length is provided by an appropriate material, and a water outlet 15 corresponding to the water inlet 2a of the horizontal gutter 2 is provided at the center of the base plate 14, similarly to the first embodiment. Are provided in the longitudinal direction and the direction perpendicular to the transverse direction, and are provided from the divided flowing water port 15a which opens at a required interval in the longitudinal direction.

Similarly, with respect to the rake-removing wind regulating plate 16, similarly, the bottom edge end surface 16 a is integrally formed on the upper surface of the base plate 14 from a suitable plate material of a required thickness and a triangular or trapezoidal or other shape. Connected, left and right inclined side end face 16
The b and 16c constitute a rake elimination surface, and the front and rear surfaces 16d and 16e constitute a wind elimination elimination surface.

The rake-removing air-conditioning elimination plate 16 is provided on the upper surface of the base plate 14 so as to correspond to the water outlet 15 of the base plate 14.
In addition, the right and left inclined side end faces 16 of each of the raised rake-removal and wind-regulating elimination plates 16 are aligned and erected integrally at predetermined intervals in the transverse direction with respect to the longitudinal direction of the base plate 14.
b, 16c, the angled top plate 17 is passed back and forth between the left and right top end surfaces 16b1, 16c1, and the left and right top end surfaces 6b1, 16c
c1 is integrally connected and coated, but bearing cylinders 12 and 12 are provided before and after the lower surface of the top end of the chevron top plate 17, and the bearing cylinders 12 and
At the radius r centered on 12, the right and left apical end surfaces 16b1 and 16c1 of the left and right inclined side end surfaces 16b and 16c of each of the standing rake eliminating and rectifying elimination plates 16 are cut off, and a cutout portion 16f configured for this cutout is formed. The upper half wind receiving portion 13b of the upper half of the wind cleaning plate 13 is arranged, and the shaft portion 13 at the upper end of the wind cleaning plate 13 is arranged.
a and 13a are loosely fitted to the bearing cylinders 12 and 12 on the front and rear sides of the lower surface of the top end of the chevron top plate 17 and are mounted on the shaft. Then, the comb-shaped wind receiving cleaning portion 13c in the lower half of the wind cleaning plate 13 is disposed between the front and rear surfaces of the rake elimination rectification elimination plate 16 and outside the outer surface of the rake elimination and rectification elimination plate 16, and swings right and left by wind force. This is how it works.

Since the apparatus for preventing fallen leaves from clogging with a wind gutter according to the second embodiment of the present invention is constituted as described above, the wind cleaning plate 13 has shafts 13a, 13a at the upper end.
Rotating like a pendulum about
6 is to remove the fallen leaves and the like entering inside and outside between the front and rear surfaces of the base plate 6, and to constantly clean the divided water outlet 15a of the base plate 14.

As shown in FIG. 8, the wind flowing between the front and rear surfaces of the rake elimination and wind elimination plate 16 has its exit area cut off by the wind cleaning plate 13 and halved compared to the entrance area. Since it becomes smaller, the wind speed can be increased, and the fallen leaves near the exit can be blown off. When the wind is in the opposite direction, the cleaning operation can be performed in exactly the same manner.

The bearing cylinders 12 and 12 may be attached to the upper part of the rake-eliminating and air-conditioning elimination plate 16, and are not limited to the angled top plate 17. Also, regarding the wind cleaning plate 13,
Immediately below the upper shaft portion 13a is the comb-shaped wind receiver cleaning unit 1.
3c, the upper half wind receiving portion 13b may not be provided. At this time, there is no cut portion having a radius r centered on the bearing cylinders 12 and 12 above the rake-removing and wind-controlling plate 16.

As shown in FIG. 11, the apparatus for preventing fallen leaves from being clogged with rain gutters according to the second embodiment of the present invention can be applied to a square gutter. In addition, it is needless to say that the rain gutter litter prevention device 1 of the first embodiment can be similarly applied to the square gutter 18.

The litter clogging prevention device 1 for rain gutters according to the first embodiment of the present invention and the litter clogging prevention device 11 for rain gutters equipped with a wind cleaning plate according to the second embodiment include a conventional gutter 2 and a down gutter shown in FIG. 3 has been described, but it can also be implemented in an embodiment in which the horizontal gutter 2 is connected to the vertical gutter 3 as shown in FIG.
