Description

Window system equipped with appearing and disappearing type insect screen}

The present invention relates to a window system equipped with an insect screen, and more particularly, to a window system equipped with an infestation type insect screen having an insect screen capable of unfolding and concealing in conjunction with opening and closing of a window.

Windows to separate the indoor space of a building from the outside play an important role in ventilation and temperature maintenance as well as lighting. catalog is being developed.

On the other hand, when the window is open, pests such as various flying insects and mosquitoes can penetrate into the room, so almost all windows are equipped with insect screens. The insect screen is a mesh-like sheet that allows air to pass through and blocks pests, and is mounted on the outside of the window frame.

By the way, when the window is open, the insect screen performs its original function, such as passing wind and preventing the invasion of pests, but when the window is closed, it only covers the view of the indoor occupant and is virtually unnecessary. If you do not open the window, there is no need to use the insect screen. Moreover, as long as the insect screen is used as a built-in, it is bound to suffer damage such as being contaminated with various dust and holes over time.

In order to solve this problem, a technology in which an insect screen is applied in a roll screen manner has also been proposed. For example, in Korean Registered Utility Model Publication No. 20-0218128, in a window installed to be able to slide left and right on a door frame, a vertical frame provided on one side frame of the window and having a draw-out hole extending vertically on one side thereof; A fixed shaft vertically penetrating the vertical frame so as to be rotatable; An insect screen whose one side is fixed and wound at the same time as the outer diameter of the fixed shaft and whose other side flows out of the draw-out hole of the vertical frame; A fixing member fixed to the other end of the insect screen and having a plurality of attachment members made of metal on one surface protruding; Disclosed is an insect screen for a window made of an elastic member fixed to a central region of a fixed shaft, one side of which is fixed to support the withdrawal of the insect screen, and a fixing device provided on a door frame to fix the insect screen when the insect screen is pulled out.

However, the disclosed insect screen for windows has a problem that the insect screen can be easily released by, for example, strong winds, since the deployed state of the insect screen is maintained only by magnetic force. For example, when wind pressure is applied to the insect screen, the attachment member is separated from the magnetic body, and at this moment, the insect screen goes into the vertical frame due to the action of the elastic member. In addition, since the insect screen is built into the frame of the window, the window is heavy and requires a lot of force during opening and closing.

Domestic Registered Utility Model Publication No. 20-0218128 (insect screen for windows) Korean Patent Laid-Open Publication No. 10-2021-0076568 (Windows and doors that select various blocking by moving the roll body with dustproof net and insect screen)
