Abstract

(57) [Summary] [Purpose] If the solids contained in the drainage from the roof of the building or the veranda are clogged in the drainage pipe leading to the sewer from the vertical gutter, the inside of the drainage pipe can be easily cleaned and cannot be removed. Provide a possible drain cover. [Structure] A hook (6) covering the upper end of the drainage pipe (3) is hung vertically from the lower part of the outer wall of the cylinder (5) that is externally inserted into the downpipe (2) and inserted into the drainage pipe (3). In the drainage pipe cover (1), a screw hole (7) is provided at the upper end of the cylinder of the drainage pipe cover (1), or a locking ridge (9) in which the lower end edge of the cylinder (5) is bent inward. ) And screw the screw (8) with the screw hole (7) and slide the drainage pipe cover (1) upwards to press it against the outer wall of the downpipe (2) to lock it, or down the downpipe (2). The locking projection (9) is configured to be locked in the locking groove (10) provided in the.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drain pipe cover provided for cleaning a drain pipe by connecting a drain gutter such as a rooftop of a building or a balcony to a drain pipe open to the ground for draining to the sewer. .

[0002]

[Prior art]

 Conventionally, drain gutters such as roofs of buildings and balconies are laid so that the lower end is directly inserted into a drain pipe that is buried in the ground leading to the sewer and opens on the ground surface.

[0003] Recently, fallen leaves of trees such as rooftops and balconies flow into rainwater along drain pipes into a drain pipe, and drainage of a washing machine installed on a balcony also drains into a drain pipe through a drain pipe. The drainage pipe may be blocked because it is bent to the sewer, so a drainage pipe cover may be installed between the vertical gutter and the drainage pipe to allow the drainage pipe cover to be lifted up or removed. It has come to be constructed so that the inside of the drainage pipe can be cleaned.

[0004]

[Problems to be solved by the device]

 As mentioned above, the solids contained in the drainage from the rooftop of the building or the veranda may flow into the drainage pipe that leads to the sewer through the vertical gutter, which may clog the drainage pipe. A drain pipe cover has come to be attached between the gutter and the drain pipe, but if the drain pipe cover can be removed for cleaning, it may be stolen. It was troublesome because it was necessary to clean the drain pipe while moving the cover upward and holding it so that it would not fall.

The present invention has been conceived in order to solve the above drawbacks, and an object thereof is to provide a drain pipe cover which is easy to clean and cannot be removed.

[0006]

[Means for Solving the Problems]

 As a result of studies to achieve the above-mentioned object, the present invention has found that the cylindrical portion which is attached to the lower end of the down gutter and is fitted into the drainage pipe and which covers the cleaning notch provided on the front surface of the lower end of the down gutter has the lower end. It is possible to solve this by installing a hook attached to the drain pipe and attaching a screw hole to the upper end. It is advisable to insert a butterfly screw into the screw hole. Instead of the screw hole, bend the lower end of the cylindrical part of the drainage pipe cover inward to provide a locking ridge to clean the vertical gutter. A notch is formed on the outer surface slightly above the upper end of the notch for use to engage the locking ridge, and the drain pipe cover is slid up and fixed or engaged while it is inserted into the vertical gutter. You should stop it. It should be noted that, instead of the locking ridge, a parallel cut may be made from the lower end of the cylindrical portion to form a locking piece.

[0007]

【Example】

 The present invention will be described with reference to the embodiments shown in the drawings. The drain pipe cover (1) according to the present invention, as shown in FIGS. 1 and 2, is externally inserted into the downpipe (2) and is inserted into the drain pipe (3), and is provided at the lower end of the downpipe (2) for cleaning. At the lower part of the outer wall of the cylinder (5) with a length covering the cutout (4), a hook (6) covering the upper end of the drainage pipe (3) is hung from the outer wall to The upper end is provided with a screw hole (7). The screw (8) may be screwed into the screw hole (7), or a butterfly screw or the like may be brought into the screw hole (7) during the work.

As shown in FIG. 3, the drainage pipe cover (1) is bent inward at the lower end to form a locking projection (9), and a notch for cleaning the vertical gutter (2) ( 4) Provide a locking groove (10) cut from the upper side on the side wall surface above the upper edge so that the lower end is horizontal, and slide the drain pipe cover (1) upward on the surface of the downpipe (2). The locking ridge (9) may be configured to be locked in the locking groove (10), and instead of the locking ridge (9), the locking ridge (9) is cut in parallel with the protrusion or the lower edge to form a cantilever beam. It does not matter even if a locking piece is formed and locked in the locking groove (10) provided in the vertical gutter (2). It should be noted that the drain pipe cover (1) is preferably made of a stainless steel plate or the like, which is not corrosive for beauty and is lightweight.

[0009]

[Effect of device]

 Since the drainage pipe cover of the present invention is configured as described above, the drainage flowing down the downpipe can be made to flow into the drainage pipe without the risk of leaking outside, and when cleaning the inside of the drainage pipe. A butterfly screw may be screwed into the screw hole, and the drainage pipe cover may be slid upward and the butterfly screw may be pressed against the vertical gutter to secure it.The same type of drainage pipe is provided with locking ridges instead of screw holes. The cover may be slid upward and locked in the locking groove. In the latter case, the locking can be easily released by rotating the drain pipe cover after cleaning.
