Description

Technical Field

[0001] The invention relates to a building energy-saving heat-insulating casement window, and in particular to a building energy-saving casement window which can be used as an outside-opening window by simply changing hardware accessories and installation directions, has a detachable invisible mosquito-proof screen, and can be made of a stainless steel mesh, and has safety protection, anti-theft and mosquito-proof functions. Background Art

[0002] At present, aluminum alloy energy-saving doors and windows have become a widely used building material in the market. With the development of society, consumers' requirements for aluminum alloy doors and windows are not only limited to beauty, elegance and practicality, but they pay more attention to the comprehensive functions of aluminum alloy doors and windows, such as safety, anti-theft, prevention of children falling from high buildings, mosquito-proof screens, hidden screens to prevent rat bites, and micro-ventilation.

[0003] The higher-end "system windows and doors" on the market have wider cross-sections, such as the common 90 series, 100 series, and 108 series. The solutions to the above functions achieved by increasing the width are as follows: (1) Anti-mosquito and anti-rat functions: the screen fan is made of the same (or similar) aluminum profile as the opening fan, and a stainless steel screen is embedded, commonly known as "diamond screen". Although it solves the problem of anti-mosquito and anti-rat, its disadvantage is that the wire diameter of "diamond screen" is relatively thick, which affects the lighting and viewing, and the cost is high. (2) Anti-theft and child anti-falling function: the aluminum cross-section width is increased between the opening glass fan and the "diamond screen" screen fan to install a fixed anti-falling railing. The disadvantage is that when a fire occurs in a high-rise building, the safety anti-falling railing is fixed and cannot be opened, which affects escape. (3) The function of screen fans is only used in summer. Screens are not needed most of the time throughout the year. However, steel screen fans are not easy to disassemble or store when not in use. They are exposed outdoors for a long time and collect dust, making them difficult to clean.

[0004] (4) In the current market, there are also high-end doors and windows made of invisible screens, but the screens can only be made of nylon or fiber mesh to make roll-type invisible screens. The disadvantages of nylon or fiber mesh are that they are not rat-proof, have poor weather resistance, and are prone to damage. Therefore, invisible screens have not been well promoted in system doors and windows, especially in system doors and windows with integrated window screens. For example: Invention patent authorization announcement number: CN100545410C discloses "a multifunctional casement window" one of the multifunctional functions of which is the "invisible screen" function. This window is an invention patent product, and the invisible screen used is the invention patent product of "a scroll invisible screen" disclosed by authorization announcement number CN102041962B. This invention only designs a limiting mechanism so that the screen can be limited at any point in the screen track. The casement window can only be opened or closed, and the significance of designing a limit at any point is not great. This invention does not design a spring torque adjustment mechanism, and the spring torque cannot be freely adjusted. Therefore, the invisible screen used in the invention patent window can only be made of nylon mesh or fiber mesh as a scroll invisible screen. At present, there is no multifunctional door and window invisible screen on the market that can realize the use of stainless steel screen as a multifunctional door and window invisible screen.

[0005] (5) The aluminum profiles for inward-opening windows and outward-opening windows on the current market are not universal. The aluminum profiles for inward-opening windows cannot be used to make outward-opening windows, and vice versa. As a result, door and window companies have many profile molds and many types of aluminum profiles in stock, which puts great pressure on profile processing and inventory, occupies a lot of capital, and the lack of aluminum profiles for inward and outward casement windows also brings huge waste.

[0006] (6) When the existing casement windows need to be double-opened, a false middle sash is used to fasten the left or right glass sash with screws. Therefore, the opening sash is naturally divided into "large sash" and "small sash". The opening middle seam is not centered and the screws are exposed, which affects the appearance. Summary of the invention

[0033] Advantages and beneficial effects of the present invention:

[0034] The present invention is a double-opening casement window (left-opening window, right-opening window), which not only has good ventilation effect, but also has the following advantages: 1. The casement window of the present invention can be used as an inner-opening window or an outer-opening window by only changing the hardware accessories and the installation direction (internal and external aluminum materials can be used universally), and the function remains unchanged, saving aluminum molds and costs. 2. The screen of the invisible screen window of the present invention can use a stainless steel mesh to make a reel invisible screen window, which is mosquito-proof and rat-proof, weather-resistant and not easy to damage. 3. The present invention is provided with two invisible screen windows. After the two screen fan handles on the two invisible screen windows are moved close to a certain position, the handle plug-in on one of the screen fan handles is inserted into the handle slot on the other screen fan handle to complete the opening of the screen fan. When closing, just take out the handle plug-in from the handle slot. 3. The design of the first glass sash plug-in, the second glass sash plug-in, and the third glass sash plug-in of the present invention is that when double-opening, the opening gap is always at the center line of the glass sash window. The screw is driven into the first C-shaped notch on the third glass sash plug-in, and the screw penetrates the second C-shaped notch on the first glass window sash to set the third glass sash plug-in on the sash frame of the first glass window sash. After opening, no screw can be seen, which plays an aesthetic role. It is obviously better than the existing market that uses a false center bar to achieve double opening, which deviates from the center line of the opening gap at the beginning and the screws are exposed outside, which is not aesthetically pleasing. 4. The design of the guardrail of the present invention can play a role in safety protection, preventing children from falling, and preventing theft. 5. The invisible screen window of the present invention can be disassembled for easy cleaning. 6. The guardrail of the present invention is locked by the guardrail handle lock. When a fire occurs, the guardrail handle lock can be opened to facilitate escape and rescue. 7. The guardrail of the present invention is a solid round rod of stainless steel with a diameter of about 5mm. The solid round rod can be the same color as the aluminum doors and windows or painted black. The solid round rod is installed in the guardrail frame, and one is installed every 8-10 cm. After being tightened and straightened by the hexagonal screw nut, it will not bend or deform due to the tension, and has safety protection and anti-theft functions; the diameter of the drilled hole on the guardrail frame is 3.2mm~3.5mm, and the round rod will no longer extend into the frame after passing through the guardrail frame. The advantage is that when the stainless steel solid round rod is tightened by the hexagonal wrench, the guardrail frame will not be deformed due to excessive tension. The round rod has a thin diameter and is painted black and has an invisible function. Whether viewed from a distance or close up, the guardrail is inconspicuous, as if there is no railing. The advantage is that the field of view is increased without blocking the line of sight. The guardrail and the doors and windows are integrated, which significantly enhances the beauty of the doors and windows. BRIEF DESCRIPTION OF THE DRAWINGS

The left opening window 2 and the right opening window 3 of the second embodiment are inward opening windows. When the left opening sash 2 and the right opening sash 3 are opened inward, the sides of the two guardrails 8 that are away from each other are respectively hinged to the outer frame 1 through hinges.

[0083] Embodiments 1 and 2 of the present invention are only two preferred embodiments. In other embodiments, the locking point on the first cornering device 767 is not limited to one, but may be multiple, and the locking point on the second cornering device 778 is also not limited to one, but may be multiple. In other embodiments, the guardrail 8 may also be other common guardrails without the invisible function.

[0084] Advantages and beneficial effects of the present invention:

[0085] The present invention is a double-opening casement window (left-opening window, right-opening window), which not only has good ventilation effect, but also has the following advantages: 1. The casement window of the present invention can be used as an inner-opening window or an outer-opening window (inner and outer aluminum materials can be used universally) by only changing the hardware accessories and the installation direction, and the function remains unchanged, aluminum molds are saved, and costs are saved. 2. The screen of the invisible screen window of the present invention can use a stainless steel mesh to make a scroll invisible screen window, which is mosquito-proof and rat-proof, and has strong weather resistance and is not easy to damage. 3. The design of the first glass fan plug-in, the second glass fan plug-in, and the third glass fan plug-in of the present invention is that when the double opening is carried out, the opening seam is always at the center line position of the glass fan window, and the screw is nailed into the first C-shaped notch on the third glass fan plug-in. The screw penetrates the second C-shaped notch on the first glass window fan and sets the third glass fan plug-in on the fan frame of the first glass window fan. After opening, no screw can be seen, which plays a beautiful role; it is obviously better than the existing market that uses a false middle stile to realize double opening, and the opening is deviated from the center line of the opening seam and the screw is exposed outside, which is not beautiful. 4. The design of the guardrail of the present invention can play the role of safety protection, child fall prevention and theft prevention. 5. The invisible screen window of the present invention can be disassembled for easy cleaning. 6. The guardrail of the present invention is locked by the guardrail handle lock. When a fire occurs, the guardrail handle lock can be opened to facilitate escape and rescue. 7. The guardrail of the present invention is a stainless steel solid round rod 84 with a diameter of about 5mm. The solid round rod can be the same color as the aluminum doors and windows or painted black. The solid round rod is installed in the guardrail frame, and one is installed every 8-10 cm. After being tightened and straightened by the hexagonal screw nut, it will not bend or deform due to the tension, and has safety protection and anti-theft functions; the diameter of the hole drilled on the guardrail frame is 3.2mm-3.5mm, and the round rod 84 will no longer extend into the frame after passing through the guardrail frame 81. The advantage is that when the stainless steel solid round rod is tightened by the hexagonal wrench, the guardrail frame will not be deformed due to excessive tension. The round rod has a thin diameter and is painted black and has an invisible function. Whether it is viewed from a distance or close up, the guardrail is inconspicuous, as if there is no railing. The advantage is that it increases the field of vision, does not block the line of sight, and the guardrail is integrated with the doors and windows, which significantly enhances the beauty of the doors and windows. Figure 12 to Figure 14 .

[0086] The sliding mechanism (slide rail, vertical frame, etc.) of the invisible screen window can be the same plastic profile, with plastic slide grooves embedded inside. Upper and lower plastic handle heads in opposite directions are provided at both ends of the screen fan handle. The plastic handle heads are assembled on the aluminum ends of the screen fan handle to form the handle of the invisible screen window. The slider 39 is provided with a slide rail groove 35 that cooperates with the slide rail 9. One end of the slider 39 is provided with a third card groove 36 for accommodating the screen 5, and a pin hole 37 is provided for installing a pin to fix the screen 5 in the third card groove 36. The slider is used to move on the slide rails on the upper and lower sides of the outer frame to achieve the stretching and contraction of the screen window. Since a handle plug-in is provided on one screen fan handle and a handle slot is provided on the other screen fan handle, the handle plug-in can be inserted into the handle slot and locked, which can prevent the screen from wrinkling and prevent the wind from blowing the screen away, so as to achieve the purpose of mosquito prevention, and also play a role in sealing and preventing the handle and screen from rebounding.

[0087] The connection between the invisible screen mesh and the screen tube and the screen fan handle is embedded, which solves the embarrassment that the invisible screen mesh in the current market can only be made of nylon mesh and adhered to the screen tube with double-sided tape. The present invention can use stainless steel screen mesh to make invisible screen windows to achieve the purpose of preventing rats from biting.

[0088] The embodiments described in the present invention are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made to the technical solutions of the present invention by engineers and technicians in this field should fall within the protection scope of the present invention. The technical contents for which protection is sought in the present invention have all been recorded in the claims.
