Door-sheet foldable screen window

Abstract

The present invention provides a door plank storable and superposable screen window. Under the condition of utilizing previous window frame, having nothing to do with opened position of glass door, it can use screen window to make simple and reliable coverage. Said invented door plank storable and superposable screen window has left and right storage boxes for holding the screen roller made up by rolling up screen, and comprises latch hook, coupling bar, upper and lower guideways, the left and right storage boxes are freely fixed on the upper and lower guideways, according to the requirements the left and right storage boxes can be slided, and can be formed into square frame together with upper and lower guideways, and the screen can be spread and laid on said square frame so as to form the invented door plank storable and superposable screen window.

Description

technical field [0001] The invention relates to a collapsible screen window, which is equipped with upper and lower guide rails at the opening of the window frame, so that the storage box for storing gauze rollers that can be drawn out and wound freely inside can be kept to slide freely in the left and right horizontal directions, and can be used The slide of this storing box, as required, freely forms the door panel shape screen window at predetermined position, also makes the screen window formed in this way slide freely. Background technique [0002] In the past, the window frames around the openings of buildings, especially the screen windows used in double-sliding window frames, used a square screen window frame to fix the four sides of the mesh screen (hereinafter referred to as "door screen window"). ), generally the upper and lower horizontal frames of the window frame that form the window frame are adorned to slide freely on the upper and lower screen door rails of ...

AI Technical Summary

Problems solved by technology

However, for example, when storing a roller-type screen window formed by elastically winding the gauze into a gauze roll that is freely unfolded and retracted, or setting another window frame on the outside of the window frame and placing the gauze on the other window frame The pleated screen window that is kept to be folded and unfolded freely in the horizontal direction cannot use the screen door rail of the existing window frame horizontal frame because the unevenness of the upper and lower frames of the window frame that forms the window frame hinders the smooth unfolding and stowing of the screen net. , it is necessary to attach a special screen door track, which will increase the cost

In addition, in the roller-type screen window, because the storage box for winding and storing the gauze and the vertical frame fixed to one end of the gauze are pulled together through the gauze, when the unfolded and laid gauze is subjected to wind pressure, the inside of the storage box The excess gauze reeled on the winding shaft is pulled out by the wind pressure, and the unfolded and laid gauze is bent, and a large gap occurs between the upper and lower ends of the gauze and the upper and lower frames of the window frame, which damages the airtightness. There are also disadvantages such as loss of insect repellent effect

[0006] In addition, in this roller-type screen window, when the gauze that is unfolded and laid to roughly cover the opening of the window frame is intended to be rolled up and stored as a gauze drum in the storage box, the external dimensions of the gauze drum itself are significantly changed. Larger, the size of the storage box itself to store the gauze roller is also significantly larger, and the installation of the roller screen window is also significantly affected by the situation that the storage box cannot be provided with sufficient installation space according to the position of the window frame. limited disadvantage

[0007] Also, because the roller-type screen window is completely slid in the window frame by means of the storage box to unfold and lay the screen, according to the type of the window frame opening, for example, the window is opened outward or the window frame is slid up and down, etc., it is required to manufacture according to its Roller screens with different types of window frame openings. In addition, because the opening and closing directions of the screen are randomly different from left to right, it lacks versatility for various window frames, and various roller screens according to various window frames are required. , There is also a disadvantage that product management from roller screens to construction becomes very complicated
