Description

[Detailed description of the invention]

[0001]

Industrial Applicability The present invention is intended to clean the inside of a drainpipe at the connection between a drainpipe on the roof of a building, a veranda, etc. and a drainpipe opening above the ground to drain to sewers. The present invention relates to a drain pipe cover to be provided.

[0002]

2. Description of the Related Art Conventionally, a drainpipe for draining a building roof, a veranda, or the like is buried in the ground for drainage to a sewer and the like, and is directly connected to a drainage pipe opening to the ground surface below the downpipe. The pipe is constructed so as to be inserted.

Recently, falling leaves and the like from the rooftop or veranda flow into the drainage pipe through the downspout along with rainwater,
Dust that has been swept out to the veranda may flow into the drainage pipe through the downspout along with water sprinkling, etc., and a drainpipe cover is installed between the downpipe and the drainpipe. In order to prevent the dust from clogging the drain pipe, the drain pipe cover can be removed, and the drain pipe can be cleaned.

[0004]

As described above, solid matter contained in drainage from the roof of a building or a veranda flows into the drainage pipe through the downspout, and the drainage pipe is bent from the opening. Therefore, the drain pipe may be settled and clogged in the drain pipe, and a drain pipe cover has been installed between the downspout and the drain pipe to clean the drain pipe. If it is made possible, it may be stolen, and if it is not removed, it will be necessary to lift and hold the drain pipe cover to clean it.

The present invention has been conceived to solve the above-mentioned drawbacks, and has as its object to provide a drain pipe cover that is easy to clean and cannot be removed.

[0006]

According to the present invention, as a result of investigations to achieve the above object, the drain pipe cover is molded using a lightweight stainless steel plate, and is externally inserted at the lower end of the downspout and inserted into the drain pipe. The cylinder covers a cleaning notch provided at the front of the lower end of the downspout, and has a length that cannot be removed after installation. When cleaning, the drain pipe cover is slid upward with the outer pipe inserted into the downspout, exposing the cleaning notch provided in the downpipe, and locking and holding it on the outer surface of the downpipe. That is the solution. The locking mechanism is formed by bending the lower end of the cylindrical portion of the drain pipe cover inward to form a locking ridge, or by cutting in parallel from the lower end and bending inward to form a locking piece, and cutting the downspout. A locking groove may be formed in the outer wall surface above the upper end of the notch, and the locking ridge or the locking piece may be locked in the locking groove, and a screw hole is formed in the cylindrical portion. It is permissible to use a thumbscrew or the like to lock the hole in the outer surface of the downspout.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS 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 is formed using a lightweight stainless steel plate, and has an inner diameter larger than the outer diameter of the downspout (2) and a lower end inserted into the drain pipe (3) as shown in FIG. When installed, it covers a cleaning notch (4) provided at the front lower end of the downspout (2) and has a length that cannot be removed. A hook (6) covering the upper end of the drain pipe (3) is vertically provided, and a part of the edge is bent inward at the lower end of the cylinder (5) to provide a locking ridge (9). The notch (4) of the downspout (2) is configured to be locked in a locking groove (10) provided on the outer surface above the upper end edge of the notch (4). The locking ridge (9) may be formed as a cantilevered locking piece by making a cut parallel to the projection or the lower edge, and the locking may be released by rotating the drain pipe cover.

In the embodiment shown in FIG. 2, a screw hole (7) is formed in the cylinder (5) of the drain pipe cover (1), and the drain pipe cover (1) is attached to the downspout (2). The drain pipe cover (1) is slid upward by sliding it upward, screwing a thumb screw (8) or the like into the screw hole (7) and pressing against the outer wall side surface of the downspout (2). The tip of the thumb screw (8) may be locked in a locking hole provided in the outer wall side surface of the downspout (2).
The drain pipe cover (1) may be formed of a stainless steel plate that is beautiful, does not corrode, and is lightweight.

[0009]

[Effect of the Invention] The drain pipe cover of the present invention is configured as described above, so that the drain water flowing down the downspout can flow into the drain pipe without fear of leaking outside, and the drain pipe is cleaned. In this case, the drain pipe cover may be slid upward and latched to the downspout, and since the drainpipe cover cannot be removed from the downspout, there is no fear of theft.
