Energy-saving building casement window with security protection, anti-theft and anti-mosquito functions

Abstract

The invention relates to an energy-saving building casement window with security protection, anti-theft and anti-mosquito functions. The casement window comprises an outer frame,a left fan, a right fan, a middle stile, a fixed fan; the left fan and the right fan comprise glass fans, invisible window screens and guardrails respectively from indoor to outdoor or from outdoor to indoor in turn; and the invisible window screens comprise screens, window screen pulls, reels, sliding chains and rails. When the two window screen pulls on the two invisible window screens come together at a certain position, the window screens can be opened by inserting a pull plug-in of one of the window screens into a pull slot of the other window screen and the window screens can be closed by taking the pull plug-in out of the pull slot. The casement window disclosed in the invention is a double-direction casement window that is not only great in ventilation effect, but also can be changed between an inswinging casement window and an outswinging casement window by changing hardware accessories and installation direction. According to the invention, the reel invisible window screens can be made of stainless steel meshes, which are anti-mosquito, rodent-protected and robust.

Description

technical field [0001] The invention relates to building energy-saving and heat-insulating casement windows, in particular to a casement window that can be opened inwardly by changing the hardware fittings and installation direction, can be used as an outwardly openable window, has detachable invisible mosquito screens, and Stainless steel mesh can be used to make gauze, which is a building energy-saving casement window with safety protection, anti-theft and anti-mosquito functions. Background technique [0002] At present, aluminum alloy energy-saving doors and windows have become widely used building materials in the market. With the development of society, consumers' requirements for aluminum alloy doors and windows are not limited to aesthetics and practicality, but pay more attention to the safety and anti-theft of aluminum alloy doors and windows. , anti-falling of high-rise children, screen window anti-mosquito, hidden screen anti-rat bite, micro-ventilation and other...

AI Technical Summary

Problems solved by technology

[0003] The higher-end "system doors and windows" on the existing market have a wider cross-section, such as: the common 90 series, 100 series, 108 series, etc., and the above-mentioned functions are realized by increasing the width. The solution is: (1) Anti-mosquito and anti-rodent function: the same (or similar) aluminum profile as the opening fan is used to make a gauze fan, embedded with a stainless screen, commonly known as "golden gauze", although it solves the problem of anti-mosquito and anti-rat, but its shortcomings The wire diameter of "Golden Steel Yarn" is relatively thick, which affects the lighting and viewing, and the cost is high

(2) Anti-theft and anti-falling functions for children: It is to increase the cross-sectional width of the aluminum material between the opening glass fan and the "golden steel yarn" yarn fan to install a fixed anti-falling barrier. The safety anti-fall barrier is fixed and cannot be opened, which affects the escape

(3) The function of the screen fan is only used in summer. During most of the year, the screen window is not needed. However, the gold steel screen fan is not easy to disassemble or store in the season when it is not in use, and it is exposed outdoors for a long time Collect dust, not easy to clean

[0004] (4) In the existing market, invisible screens are also used to make high-end doors and windows, but the screen is limited to the use of nylon mesh or fiber mesh to make scroll-type invisible screens. The disadvantage of nylon mesh or fiber mesh is that it is not resistant to rat bites , poor weather resistance, and damage tolerance, therefore, invisible screens have not been well promoted in system doors and windows, especially in system doors and windows with screens integrated

For example: Invention patent authorization announcement number: CN100545410C discloses "a multifunctional casement window", one of which has the function of "invisible screen window". This window is an invention patent product, and the invisible screen window used is the authorized announcement number. It is the invention patent product of "a scroll-type invisible screen window" disclosed in CN102041962B. This invention only designs a limit mechanism, so that the gauze can be limited at any point in the yarn rail movement track, and the casement window can be opened. The degree of completeness is not great, it is either open or closed, and the design of the limit at any point is not very meaningful. This invention does not design a spring torsion adjustment mechanism, and the spring torsion cannot be adjusted freely. Therefore, the invisible yarn used in the patented window of this invention Net, only nylon net or fiber net can be used to make roll-type invisible screen window

At present, there is no invisible screen window with multi-functional doors and windows in the market, which can realize the multi-functional doors and windows with stainless steel gauze as invisible screen window

[0005] (5) The aluminum profiles for inward-opening windows and outward-opening windows are not universal in the existing market, and the aluminum profiles for inward-opening windows cannot be used to make outward-opening windows, and vice versa

As a result, door and window enterprises have many profile molds and many types of aluminum profile stock, which puts great pressure on profile processing and inventory, and takes up a lot of funds.

[0006] (6) When the existing casement windows need to be opened double-opened, the false stiles are used to fasten the left glass fan or the right glass fan with screws, so the opening fan is naturally divided into "big fan" and "small fan". , the opening seam is not centered, and the screws are exposed, which affects the appearance
