JPH1181508A - Insect screening for exhaust duct - Google Patents

Abstract

PROBLEM TO BE SOLVED: To easily take out an insect screening by stretching the screening into a cylindrical body to form the insect screening having a handle, and inserting the insect screening into a duct to draw it near with the handle in the case the insect screening is cleaned. SOLUTION: A cylindrical body 1 curving a galvanized sheet steel in the shape of a circle is formed, and interlocking sections 11 are projected to the outside of the cylindrical body 1 at an interval in the circumferential direction. An insect control wire netting 2 is stretched to the inside of the cylindrical body 1, and a steel pipe handle 3 formed in the shape of a horizontally straight line is mounted to the inside of the cylindrical body 1 to form an exhaust duct insect screening A. Then, in order that the said exhaust duct insect screening A is inserted into the duct, the handle 3 is held to insert it into the duct, and it is interlocked with the inside of the duct by means of the interlocking sections 11 provided in the cylindrical body 1 to fix the insect screening A. Accordingly, in the case the wire netting 2 is stained, the handle 3 is held to make it possible to take it out from the inside of the duct to an indoor side.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insect net for an exhaust duct.

[0002]

2. Description of the Related Art Conventionally, an insect net is provided at an outlet of an exhaust duct to prevent insects and the like from entering the exhaust duct.

[0003]

However, as in the prior art, when an insect repelling net is stretched at the outlet of the exhaust duct, it is necessary to remove the insect repelling net from outside in order to clean the insect repelling net. It was inconvenient.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems in the conventional insect net of an exhaust duct, and an object thereof is to solve the conventional problems and to clean the insect net. Therefore, it is an object of the present invention to provide an insect repellent net for an exhaust duct without having to remove the insect repellent net from outside.

[0005]

The insect net for an exhaust duct according to the present invention is characterized in that the net is stretched in a tubular body and a handle is provided in the tubular body.

In the present invention, the cylindrical body may be any one that can be mounted in a duct, and may be a cylindrical body having a circular cross section according to the shape of the duct to be mounted. It may be a rectangular cylindrical body having a rectangular cross section.

[0007] The material of the tubular body is not particularly limited as long as a net can be stretched inside the tubular body, and is not particularly limited. For example, a metal such as iron, stainless steel, aluminum or the like is used. In addition, synthetic resins such as hard vinyl chloride resin, polycarbonate, and FRP can be used.

The material of the net is not particularly limited as long as it can be expected to have an insect repellent function. For example, in addition to metals such as iron and stainless steel, vinyl chloride resin and chloride Synthetic resins such as vinylidene resin can be used.

[0009] The handle may be any as long as the tubular body can be taken out of the duct by grasping the handle. Examples of the material include hard vinyl chloride resin, metal such as iron and stainless steel, and the like. Synthetic resins such as polyethylene and polystyrene and wood can be used.

[Operation] In the insect repellent net for an exhaust duct of the present invention, since the net is stretched in a cylindrical body and a handle is provided in the cylindrical body, the insect repellent net for an exhaust duct of the present invention is provided in the duct. The insect repellent net can be stretched in the duct by inserting the airbag, and when cleaning the insect repellent net, the insect repellent net for an exhaust duct of the present invention can be taken out of the duct by pulling it with a handle.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing an example of the insect net for an exhaust duct of the present invention, FIG. 2 is a side view of the insect net for an exhaust duct of the present invention shown in FIG. 1, and FIG. It is a partially notched perspective view which shows the use aspect of the insect-control net for exhaust ducts.

In FIGS. 1 to 3, A is an insect net for an exhaust duct of the present invention, 1 is a tubular body of the insect net for an exhaust duct A of the present invention, and the tubular body 1 has a circular cross section and is made of zinc. It is manufactured by bending a plated iron plate into a circular shape. Reference numeral 11 denotes a locking portion projecting from the outer surface of the cylindrical body 1 at intervals in the circumferential direction. The locking portion 11 is formed by cutting a part of the cylindrical body 1 and raising it slightly. Reference numeral 2 denotes a wire mesh for insect repelling stretched inside the tubular body 1 and reference numeral 3 denotes a handle made of a steel pipe having a horizontal character, and both ends of the handle 3 are attached to the inner surface of the tubular body 1 by welding or the like.

Since the insect pest net A for an exhaust duct of the present invention shown in FIGS. 1 to 3 has the above structure, it is inserted into the duct 4 as shown in FIG.
The duct 4 is cylindrical as shown in FIGS. 4 and 5, and the duct 4 is installed above the wall 5 of the concrete underground storage as shown in FIG.

The insect net A for an exhaust duct of the present invention is
When inserting the insect repellent net A for an exhaust duct of the present invention into the duct 4 from the indoor side of the underground storage 5, the handle 3 may be gripped.

Since the locking portion 11 provided on the cylindrical body 1 is locked on the inner surface of the duct 4, the insect net A for the exhaust duct is provided.
Are fixed in the duct 4. When the wire net 2 of the insect net A for an exhaust duct of the present invention is contaminated by long-term use,
The handle 3 can be gripped and taken out of the duct 4 to the indoor side of the underground storage 5.

In FIGS. 3 to 5, reference numeral 41 denotes a locking projection provided on the inner surface of the distal end of the duct 4 at intervals in the circumferential direction. A does not come off the duct 4 to the outdoor side. In FIG. 3, reference numeral 6 denotes a floor plate of a building provided above the basement 5, and reference numeral 7 denotes a ground on which the basement storage 5 is installed.
