Description

[Detailed Description of the Invention] Industrial Field of Application This invention relates to a new type of insect repellent device used to take in wind at entrances, back doors, etc. of buildings.

Conventional technology Traditionally, screen doors installed at building doorways for ventilation and insect protection cover the entire doorway, so
If you want to let air in through the door, you must leave the door open.

Problems to be solved by the invention However, this made the inside of the room completely visible from the outside, which was not desirable. Also, in order to attach the screen door, a screen door mounting frame is installed inside the frame around the doorway, which makes the doorway narrower and requires opening and closing both the screen door and the door when entering and exiting, which is very inconvenient. It was hot. In addition, conventional screen doors required installation work, making them expensive. Furthermore, although the screen door can be removed when not in use, the screen mounting frame inside the door remains fixed, making it very unsightly.

The purpose of this invention is to solve the above problems, to be placed outside the gap between the door and the door when it is opened at a required angle, and to be able to play the role of insect repellent without obstructing ventilation. There is no hesitation in opening and closing, so it is easy for people to get in and out, it is very easy to install and remove, and it is inexpensive because no installation work is required, and it is easy to store after use. We are also trying to provide a convenient new type of doorway insect control device.
