Description

  The present invention relates to an eaves drain attached to a drainage port of an eaves.

  In general, on the downstream end side of the eaves, there is a drain outlet for draining rainwater in the eaves into the eaves. In order to prevent an obstacle such as a bag from flowing into the bag together with the rainwater, a drain for eaves is provided having a dust removal body having a drainage window above the drainage port (for example, a patent Reference 1).

  Specifically, a drain receiving portion for connecting the drain port and the slag etc. is provided below the drain port, and the drain receiving portion and a dust remover are fitted through the drain port, An inverted bowl-shaped dust eliminator having a plurality of drainage windows is provided above the drainage port.

Therefore, according to this eaves drain, obstructions such as fallen leaves and plastic bags collected in the eaves are blocked by the dust eliminator, and only rainwater is dredged from the drainage window through the drainage port. Therefore, the obstacle can be prevented from flowing into the bag together with rain water, and as a result, the obstacle can be prevented from clogging the bag.

  However, the conventional eaves drains have the following problems.

  That is, for example, when a sheet-like obstacle such as a fallen leaf or a vinyl bag adheres to the dust guard, a part of the drainage window of the dust guard is closed to reduce drainage efficiency. If the adhesion of the water increases and accumulates, most of the drainage window is closed, and drainage efficiency is drastically reduced.

  Therefore, if the obstacles are not removed one by one, the amount of rainwater stored in the eaves will be larger than the amount of rainwater drained through the drainage window, and rainwater will be accumulated in the eaves before long. There was a problem that rainwater overflowed from.

  In addition, in order to increase the drainage efficiency of the above-mentioned dust eliminator, in order to replace the existing trash eliminator with a large one, it is necessary to replace all existing drainage for the eaves, such as processing of the corresponding drain receiving part and drainage port. Because of this, the replacement work was difficult.

  The present invention aims to solve such problems, and can easily and reliably drain rainwater in the eaves over a long period of time even if obstacles such as fallen leaves and plastic bags accumulate. Provide an eaves drain that can use the existing eaves drain.

To achieve the above objective,
The eaves drain according to claim 1 is a drain for eaves comprising a drain receiving portion provided below a drain outlet of the eaves and a dust-removing body fitted above the drain receiving portion. It consists of a plurality of members that can be divided in the height direction, has a height approximately the same as the depth of the eaves, and a locking leg that is elastically biased outwardly protrudes from the lower end, In addition, a tall dust-removing body formed in an inverted bowl shape having a plurality of drainage windows is configured to be attached from above the dust- removing body, The leg portion is inserted into a drainage window provided in the dust-removing body, and the locking leg portion is reduced inward, and by its elastic force, it can be locked and attached to the dust-removing body or the drain receiving portion. On the other hand, while having a structure that can be pulled out and removed while resisting the elastic force of the locking leg, the plurality of members are formed of A locking portion formed at an end, and characterized in that the further combined with lock receiving portion formed on the upper end, has a structure that can adjust the height of the tall trash aside body according to the depth of the eaves gutter To do.

  The present invention has the following effects.

  According to the eaves drain according to claim 1, the tall dust having a height substantially equal to the depth of the eaves can be obtained by simply attaching the tall dust remover to the existing dust guard. The shield can be easily configured.

  Therefore, even if obstacles such as fallen leaves and plastic bags are somewhat accumulated on the lower end side of the tall dust guard body, most of the drainage window can be maintained open, so rainwater stored in the eaves It is possible to drain more rainwater than the amount, and it is possible to prevent rainwater from being accumulated in the eaves and overflowing from above the eaves.

  In addition, there is no need to remove the obstacles one by one, and rainwater in the eaves can be reliably drained over a long period of time.

Furthermore, the tall dust removal body, which is attached from above the existing dust removal body, has a structure that can be divided and combined into multiple parts in the height direction. The height of the body can be easily adjusted, for example, it can be easily adjusted even at the work site.

  Hereinafter, the eaves drain according to the present invention will be described with reference to the drawings.

FIG. 1 is an exploded perspective view showing a reference example of the eaves bowl drain A according to the present invention, and FIG. 2 is a longitudinal sectional view showing a state where the eaves bowl drain A of FIG. is there.

An eaves drain D of this reference example is provided with a drain receiving part 1 provided below a drain outlet T1 of the eaves T, and a dust eliminator 2 fitted above the drain receiving part 1. In the drainage for dredging, the tall dust removal body 3 having a height substantially the same as the depth of the eaves bowl T and formed in a reverse bowl shape in which a plurality of drainage windows 31 are opened is removed from the garbage. While being attached from above the body 2, the tall dust-removing body 3 is configured to be detachable from the dust-removing body 2 or the drain receiving portion 1.

  The drain receiving portion 1 is a cylindrical body having an inner diameter that is substantially the same diameter as the drain outlet T1, and is formed with a flange 11 protruding outward at the upper end of the cylindrical body, and on the outer wall on the lower end side. Is formed with a fitting step portion 12 that is fitted into the upper end of a heel or the like (not shown) so that the heel or the like (not shown) can be connected.

  Further, a screw receiving portion 13 such as a screw groove is formed in a part or all of the inner wall of the drain receiving portion 1 in the circumferential direction.

  The dust-removal body 2 is formed with a threaded portion 22 such as a screw thread in the circumferential direction on the outer wall of a cylindrical through-tube 21 that can penetrate the drain port T1. A collar portion 23 that can be locked to the drain outlet T1 of the collar T protrudes outward.

  In addition, a plurality of curved plate pieces 24 are erected upward at the upper end of the through pipe 21 (the base end of the flange portion 23), and the upper ends of the plate pieces 24 are coupled by an annular ring portion 25. Thus, an inverted bowl-shaped dust repellent body 2 having a plurality of drainage windows 26 is formed.

  And if the penetration pipe | tube 21 of the dust removal body 2 is penetrated from the upper direction of the drain outlet T1, and the screwing part 22 of this penetration pipe 21 is screwed to the screwing receiving part 13 of the drain receiving part 1, a drain receiving part The drainage part 1 and the dust remover 2 are attached to the one flange 11 and the flange 23 of the dust remover 2 with the rim of the drain outlet T1 interposed therebetween.

  The tall dust-removing body 3 has a height approximately equal to the depth of the eaves bowl T, and is formed in an inverted bowl shape in which a plurality of drainage windows 31 are opened.
