As described in Japanese Patent Application Publication No. 1-9488, it is composed of a pair of upper and lower cylinders provided with a flange and a screw portion, and screw portions (male screw and female screw) provided on both the cylinders are screwed together. The periphery of the drain hole provided at the bottom of the eave gutter is sandwiched between the flanges of the cylindrical body.

に装着されている。In this conventional free drain, as described in Japanese Utility Model Application Laid-Open No. 63-127532, a net-like dust filter for removing fallen leaves and dust is provided at the rainwater inlet of the upper cylindrical body. Are integrally protruded upward, or a net-like dust remover is detachably attached to the drainage inlet.

た。However, in the conventional free drain, when the surface of the mesh body for removing dust is completely covered with fallen leaves or the like, rainwater is not drained from the drain outlet of the eaves gutter, and the eaves gutter is not drained. Rainwater overflows and wets the fascia and exterior walls of the building. As a result, there has been a problem that the surfaces of the fascia and the outer wall become dirty or corroded.

た。[0005] Even if cleaning is performed periodically to remove fallen leaves adhering to the surface of the reticulated net, if the reticulated net is integrally formed with the upper cylindrical body, the upper cylindrical body is removed. It was not possible to remove the garbage, and the work of removing garbage at high places was troublesome and time-consuming.

２３号公報にて開示されている。By the way, before rainwater overflows from the eaves gutter,
In addition to the conventional free drain with dust rejection, the height of the rainwater inlet is made higher than the free drain with dust rejection so that the net surface of the dust repellent is covered with fallen leaves etc. A drainage device with the idea of installing a drainage pipe without a cover at the bottom of the eaves gutter is disclosed in Tokuhei 3-802.
No. 23 discloses this.

る。In this case, it is possible to visually confirm that rainwater flows down a chain gutter located below a down gutter connected to a lower end portion of a drainage pipe having no dust rejection.
It is possible to know that the wastewater drainage inlet on the free drain side with the dust rejection is clogged. However, there is a problem that two universal drains having different structures must be installed instead of installing one universal drain, which increases the installation cost and deteriorates the appearance of the building.

による建物の鼻隠し板や外壁の腐食を防止できる。(Function) In the flexible drain according to the first aspect of the present invention, the lower portion of the net-like dust removably attached to the rainwater inlet of the inner cylindrical body is a short cylindrical portion. Because a number of small holes penetrate inward and outward in the wall of the wall, the outer peripheral surface of the wall of the short cylinder part is caused by falling leaves that try to flow toward the drainage outlet of the eaves gutter together with rainwater. Even if it is covered with fallen leaves or the like, drainage of rainwater is continuously performed through the mesh portion existing above the short tube portion. For this reason, rainwater does not overflow from the eaves gutter, and corrosion of the fascia and outer wall of the building due to the rainwater can be prevented.

し板や外壁の腐食を防止できる。According to the second aspect of the present invention, a ring having a height lower than the dust remover is disposed concentrically around the mesh dust remover at a predetermined interval. Since a number of small holes penetrate the wall of the body in the inward and outward directions, fallen leaves that try to flow together with rainwater, for example, toward the drainage outlet of the eaves gutter, are captured by the outer peripheral surface of the ring body Is done. Then, the rainwater flows over the upper end of the ring body and flows into the inside of the ring body, and the drainage of the rainwater is continuously performed through a net-like dust rejection projecting upward from the upper surface of the flange of the inner cylindrical body. For this reason, rainwater does not overflow from the eaves gutter, and corrosion of the fascia and outer wall of the building due to the rainwater can be prevented.

きる。In the above embodiment, the dust remover 4 has a short cylindrical portion 42 below the hemispherical dust remover 41,
Since a large number of circular holes 43 are present in the wall of the short cylindrical portion 42, fallen leaves and the like flow into the drain outlet 52 of the eaves gutter 5 together with rainwater, and the outer peripheral surface of the wall of the short cylindrical portion 42 becomes a fallen leaf. Even if it is covered, the drainage of rainwater is continuously performed through the hemispherical dust-removal net 41 existing above the short cylindrical portion 42. For this reason, rainwater does not overflow from the eaves gutter 5 and corrosion of the fascia and outer wall of the building due to the rainwater can be prevented.

壁の腐食を防止できる。In this case, even if fallen leaves and the like flow into the drainage outlet 52 of the eaves gutter 5 together with rainwater, and even if the outer peripheral surface of the wall of the short cylindrical portion 42 is covered with fallen leaves, etc.
Since the rib-shaped projections 43a are present on the outer periphery of the wall between the third and the fourth 43, the openings of the long holes 43 are not completely covered with fallen leaves and the like and are not blocked, and the drainage of the rainwater is better. It is performed continuously. Therefore, rainwater does not overflow from the eaves gutter 5 in the same manner as described above, and corrosion of the fascia and the outer wall of the building due to the rainwater can be prevented.

Eliminate the portion corresponding to the short cylindrical portion 42 of the dust remover 4,
Instead, the lower end of the ring body 7 provided with a number of vertically long holes 71 in the wall portion is fitted and locked on the outer periphery of the flange 23 of the inner cylindrical body 2 so that the ring body 7 is mesh-like dust. Except that it is disposed concentrically and detachably at predetermined intervals around the cutout 41, it is the same as the above-described first embodiment, and therefore the same parts are denoted by the same reference numerals and description thereof will be omitted. The ring body 7 is a short tube made of hard vinyl chloride resin, and the height thereof is set to be lower than the dust remover 41. The height of the ring body 7 is about 20 mm, and a flange 72 is provided on the outer periphery of the lower end so as to protrude outward.

る。In this case, when fallen leaves and the like flow into the drainage outlet 52 of the eaves gutter 5 together with the rainwater, first, the rainwater is passed through a number of long holes 71 of the ring body 7 arranged concentrically around the net-like dust rejector 41. Flows into the drain outlet 52 of the eaves gutter 5. At this time, the fallen leaves flowing with the rainwater are captured on the outer peripheral surface of the ring body 7. And
Even if the openings of many long holes 71 are covered with fallen leaves,
Since the rainwater flows over the upper end of the ring body 7 and flows into the ring body 7, the drainage of the rainwater is continuously performed. For this reason, rainwater does not overflow from the eaves gutter 5 similarly to the above, and corrosion of the fascia and the outer wall of the building due to the rainwater can be prevented.

雨水による腐食を防止できる。According to the second aspect of the present invention, a ring having a height lower than the dust remover is arranged concentrically around the mesh dust remover at a predetermined interval. Because a number of small holes penetrate the wall of the body in the inward and outward directions, fallen leaves that flow with rainwater are caught on the outer peripheral surface of the ring body, and rainwater rides over the upper end of the ring body and Rainwater is drained through the net-like garbage repellent projecting upward from the upper surface of the flange of the inner cylinder body, preventing rainwater from overflowing from the eaves gutter, Corrosion of the outer wall due to rainwater can be prevented.
