Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a drain pipe that is attached to a drain hole opened at the bottom of an eaves gutter, a balcony, a porch, etc.

(Prior Art) As a conventional drain pipe, the one shown in FIG. 4 is known.

This conventional drain pipe consists of an upper pipe 01 and a lower pipe 02.
By screwing both cylinders 01 and 02 together, it can be attached to a drainage hole in an eaves gutter, balcony, etc. A mesh-like dust guard 04 is installed at the drainage inlet 03 at the upper end of the upper cylinder 01. is integrally formed so as to protrude from the drainage inlet 03 and face upward.

(Problem to be solved by the invention) However, in the case of such a conventional drain pipe, when it is attached to the drain hole, the dust holder 04
Because it protrudes upward from the drainage hole, it may become an obstacle during construction or other work, and sometimes cause damage to objects, especially if it is installed in a drainage hole formed within the range of people's activities, such as on a balcony. There were also cases of damage due to contact with Furthermore, when the dust cover 04 is damaged, it is extremely difficult to replace it.

(Means for solving the problem) The present invention was made with the purpose of solving the above-mentioned problems. and a net-like dust guard that is detachable from the cylindrical body, and the dust catcher is attached in either an upward position protruding from the drainage inlet of the cylinder or a downward position inserted into the drainage inlet. This means that it is possible to do so.

(Function) Therefore, in the drain pipe of the present invention, by attaching the dust guard to the cylinder body in an upward position, it can exhibit the same function as the conventional one, and by attaching it in a downward position, By not protruding from the drainage inlet of the cylindrical body, it is possible to prevent it from becoming an obstacle during construction or other work, and it is also possible to avoid contact with objects and prevent damage.

In addition, when the dust cover is installed in a downward position, in addition to the function of preventing dirt from entering, it also has a dust collection function.With this dust collection function, the dust once attached to the dust cover is washed away by rainwater. You can prevent it from getting washed away and becoming a mess.

In addition, when the dust cover is attached facing downward, the overall size becomes more compact, making it convenient for packing.

In addition, since the dust guard is removable from the upper tube, it can be easily changed and reinstalled, such as facing downward during construction and facing upward during use, and is also easy to replace. become.

Depending on the construction situation, usage situation, etc., it can be easily reinstalled from an upward position to a downward position, or vice versa.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, the configuration of the embodiment shown in FIGS. 1 to 3 will be described.

The drain pipe of this embodiment is attached to a drainage hole formed in an eaves gutter, balcony, porch, etc., and drains rainwater into a gutter such as a vertical gutter.It has a lower pipe 10 and an upper pipe molded from synthetic resin. 20 and a dust remover 30.

The lower cylinder 10 has a screw 111 and a convex ring 1 on the inner circumference.
12, and a flange part 12 integrally formed at the upper end of the cylindrical part 11, and the vertical gutter 1 is inserted into the inner periphery of the cylindrical part 11 from below. Note that the convex ring 112 is
It is formed at a lower position than the screw 111, and, as shown in FIGS. 2 and 3, restricts the insertion of the vertical trough 1 to the position where its upper end touches.

The upper cylinder 20 is screwed and fixed to the lower cylinder 10 by screws 211 formed on the outer periphery of the cylindrical part 21, and has a drainage inlet 212 at the upper end of the cylindrical part 21.
A flange portion 22 is integrally formed therein. On the inner circumference of the flange portion 22, there is approximately the flange portion 22.
A stepped portion 23 is formed which is lowered by a thickness of .

The dust cover 30 is removable from the upper cylinder 20 and is formed in a net shape with a trapezoidal longitudinal section.
An edge portion 31 is formed to be accommodated in the step portion 23 of the upper cylinder 20, and a recess portion 311 that can fit into the convex portion 231 of the upper cylinder 20 is formed in the edge portion 31.

Moreover, this dust guard 30 can be placed in either an upward state (see FIG. 2) where it protrudes from the drainage inlet 212 of the upper cylinder 20 or a downward state (see FIG. 3) where it is inserted into the drainage inlet 212. However, it is designed to be wearable.

Next, the operation of the embodiment will be explained.

First, when attaching the drain pipe of this embodiment to the drain hole 3 formed in the bottom part 2 of the eaves gutter, the flange part 12 of the lower pipe 10 is brought into contact with the lower surface of the bottom part 2 of the eaves gutter, and the upper pipe The cylindrical part 21 of 20 is connected to the drainage hole 3.
The tubes 10 and 20 are screwed together to form the respective flange portions 12 and 22.
Insert the bottom part 2 of the eaves gutter. When screwing together the lower tube 10 and the upper tube 20, the dust guard 30 is attached to the upper tube 20, and the fitting between the upper tube 20, the protrusion 221, and the recess 311 of the dust guard 30 is used. If the upper cylinder 20 is made to follow the rotational movement of the dust holder 30, the two cylinders 10 and 20 can be easily screwed together by fixing the lower cylinder 10 and rotating the dust holder 30.

Next, when attaching the dust guard 30 to the upper cylinder 20, it can be determined whether to attach it upward or downward depending on the construction situation or usage situation.

For example, as shown in the drawing, when attaching a drain pipe to the drain hole 3 formed in the bottom part 2 of an eaves gutter, the rafters etc. protrude into the eaves gutter, and if the dust guard 30 is in the upward position, it will come into contact with the rafters. In difficult construction situations, the dust guard 30 can be installed in a downward position to avoid rafters, and when installed in a drainage hole formed within the range of people's activities such as a balcony, When installed in a downward position, it can prevent it from becoming an obstacle during construction or other work, or from being damaged by contact with objects.

In addition, since the dust guard 30 is detachable from the upper tube 20, it can be easily changed and reinstalled, such as facing downward during construction and facing upward during use. Even if it is damaged, it can be easily replaced.

Furthermore, the dust guard 30 performs the function of preventing the intrusion of dust whether it is facing upward or downward, but when it is facing downward, it also functions as a dust collector. With this function, it is possible to prevent the garbage once attached to the garbage guard 30 from being washed away and scattered elsewhere by rainwater.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and any design changes or the like that do not depart from the gist of the present invention are included in the present invention. It can be done.

For example, in the embodiment, the cylindrical body is composed of a lower cylinder and an upper cylinder, but a single cylindrical body may be used. Furthermore, the shape of the dust guard is not limited to the embodiment.

Further, the dust cover may be screwed and fixed to the upper cylinder.

(Effects of the invention) As explained above, in the drain pipe of the present invention, the dust guard can be attached to the cylinder body in an upward position where it performs the same function as the conventional one. In addition, it does not interfere with work, prevents damage due to contact with objects, has a dust collection function, is compact, and can be mounted in a downward position for convenient packing.

Moreover, since the dust guard is detachable from the upper tube, it can be easily reattached from an upward position to a downward position, or vice versa, depending on the construction situation, use situation, etc. Furthermore, even if it is damaged, it can be easily replaced.
