Description

Technical Field

[0001] The utility model relates to a window cover, in particular to a casement window transformed into a window cover with a grid style. Background Art

[0002] The inward-opening casement window (hereinafter referred to as the casement window) is composed of a window frame, an opening window sash and a fixed window sash. The window frame is composed of a part embedded in the wall and a part exposed outside the wall in the shape of a square. The window frame contains an opening sash frame and a fixed sash frame. The opening window sash is a whole piece of glass installed on the opening sash frame for ventilation; the fixed window sash is a whole piece of glass installed on the fixed sash frame (the fixed sash frame includes the window frame, the center support, etc.). Since the glass on the opening window sash and the fixed window sash is a whole piece of glass, it is called a whole-glass casement window. The glass on the casement window has been maximized, so the lighting is better. In order to overcome the insufficient anti-theft effect of the casement window, anti-theft window covers are introduced on the market. The anti-theft window covers are flat metal mesh or cover-shaped metal mesh, which are generally installed on the outer walls around the window.

[0003] In buildings that do not pursue maximum lighting, in order to increase the diversity of windows and adapt to the antique architectural style, sectional windows have appeared on the market. For example, CN2780943Y discloses a pane for integrated aluminum alloy doors and windows. The pane is used in sectional aluminum alloy doors and windows as a glass frame to clamp the glass to achieve sectional aluminum alloy doors and windows. Obviously, CN2780943Y is not suitable for renovation projects, that is, sectional renovation of casement windows installed on buildings. If you want to achieve sectional windows, you can only smash the casement windows installed on the building, which causes waste.

[0004] CN208658515U discloses a modular aluminum tube material used in an aluminum alloy grille, wherein the aluminum alloy grille is a grille core 10 embedded (installed) in a grille frame 20, and the modular aluminum tube material can be used to form cross-shaped, L-shaped and T-shaped units at will, and then one or more of these units are combined together to form an aluminum alloy grille core 10 (see paragraphs 18-24 of the specification, Figure 1 -7). CN209742189U discloses another combined aluminum tube material used in aluminum alloy grilles. Various types of aluminum alloy grille cores can be made using the combined aluminum tube material and installed on a grille frame to form an aluminum alloy grille. Summary of the invention

[0005] The utility model aims to provide a window cover which is used to transform a casement window into a divided window.

[0006] The purpose of the utility model is achieved in this way: it includes an aluminum alloy grille core, which is characterized in that: it also includes a square-shaped window cover frame, an opening fan frame and a fixed fan frame are arranged in the square-shaped window cover frame, a grille core is installed in the fixed fan frame to form a window cover fixed fan, and a screen and a grille core are installed in the opening fan frame according to the inner and outer layers to form a window cover opening fan;

[0007] The specifications of the window cover frame and the casement window frame (referring to the outer and inner circle sizes of the two frames) are the same. After the window cover frame is installed on the outside of the window frame (i.e. the window cover frame is installed and fixed on the casement window frame from the outside), the window cover opening sash corresponds to the casement window opening sash, has the same outer edge size and opening direction, and the window cover fixed sash corresponds to the casement window fixed sash, including the window cover center support corresponds (aligns) with the casement window center support and fits tightly;

[0008] Install and fix the window cover frame to the casement window frame from the outside, so that the two frames and the center support inside are aligned and close to each other. At this time, the window cover corresponds to the two fixed sashes and the two opening sashes of the casement window. When ventilation is needed, open the opening sash of the casement window to the room, while the window cover opening sash is in the closed state, and the gauze on the window cover opening sash blocks mosquitoes and flies. Opening the window cover opening sash can provide a passage between the indoor and outdoor.

[0009] Compared with the prior art, the positive effects of the present invention are: after the present invention is installed on the outside of the casement window (the present invention is attached to the casement window from the outside), when the casement window is viewed from the outside, it produces the effect of a sectional casement window, and such a transformation avoids waste; secondly, since it is installed on the outside of the casement window and is an aluminum alloy grille, it also has an anti-theft effect; finally, since it is provided with an opening fan, a passage is provided for indoor and outdoor use, including an escape passage for emergency accidents.
