Description
Technical Field
[0001] This utility model relates to the field of window technology, and in particular to an outward-opening window with a hidden screen. Background Technology
[0002] In the field of architectural doors and windows, traditional aluminum-wood composite windows face several technical bottlenecks. Existing products mostly use ordinary nylon thermal break strips, which have weak resistance to deformation and weathering, leading to a decline in the window's thermal insulation performance over long-term use. Assembly gaps often arise at the profile joints due to thermal expansion and contraction, especially at the window sash opening mechanism, where jamming is common. Traditional wooden decorative components are often installed using snap-fit methods, which are prone to peeling and deformation due to environmental temperature and humidity changes. Screen systems are typically installed as independent external components, disrupting the integrity of the building facade and increasing later maintenance costs. Furthermore, the glass installation structure generally faces challenges in controlling the compression of the sealing strips, leading to potential leaks in windy and rainy weather. These technical deficiencies hinder the application and promotion of aluminum-wood composite windows in the high-end building market. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the use of ordinary nylon thermal insulation strips, which have weak resistance to deformation and weathering, leading to a decline in the thermal insulation performance of windows after long-term use. Furthermore, gaps often arise at the joints of the profiles due to thermal expansion and contraction, especially at the window sash opening mechanism, where jamming is common. Traditional wooden decorative components are often installed using snap-fit methods, which are prone to peeling and deformation due to environmental temperature and humidity changes. Screen systems are typically installed externally as independent components, disrupting the integrity of the building facade and increasing maintenance costs. In addition, glass installation structures generally face challenges in controlling the compression of sealing strips, leading to potential leaks in windy and rainy weather. These technical deficiencies hinder the application and promotion of aluminum-wood composite windows in the high-end building market, and this invention proposes an outward-opening window with a concealed screen.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An outward-opening window with a hidden screen includes a window frame and a window stile, wherein the same window sash is hinged to the inner side of the window frame and the window stile;
[0006] The window frame includes an inner profile and an outer profile, the window sash includes an inner profile and an outer profile, and the mullion includes an inner profile and an outer profile.
[0007] A first thermal break strip and a second thermal break strip are connected between the inner profile of the window frame and the outer profile of the window frame, between the inner profile of the window sash and the outer profile of the window sash, and between the inner profile of the window mullion and the outer profile of the window mullion. The first thermal break strip and the second thermal break strip are made of reinforced nylon.
[0008] The first thermal insulation strip between the inner profile and the outer profile of the window frame is fixedly connected to an equal pressure adhesive strip on one side of the window sash.
[0009] It also includes a screen window, which is fixed between the window frame and the window stile.

[0011] The reinforced nylon thermal insulation strip blocks the heat conduction path and improves thermal insulation stability; the equal pressure strip balances the internal and external pressure difference and eliminates window sash opening and closing jamming; the screen is integrated between the window frame and the window mullion to maintain the integrity of the building facade.
[0012] In one possible design, glass is pressed between the inner side of the second extruded wood trim and the outer profile of the window sash, and between the inner side of the fixed extruded wood trim and the outer profile of the window frame.
[0013] The glass has an inner sealing strip on the indoor side and an outer sealing strip on the outdoor side.
[0014] The inner side of the window sash and the first extruded wood profile are both connected to aluminum pressure lines on the side of the glass.
[0015] A snap-fit adhesive strip connects the aluminum pressure line to the inner profile of the window sash.
[0016] A second extruded wooden pressure line is installed on the outside of the aluminum pressure line by an overlapping adhesive strip;
[0017] The inner and outer glass adhesive strips, together with the pressure line fastening strip, form a triple sealing structure to prevent wind and rain leakage.
[0018] In one possible design, the inner profile of the window frame is fixedly connected to the first extruded wood profile;
[0019] A snap-fit adhesive strip connects the aluminum pressure line to the inner profile of the window frame.
[0020] The inner side of the aluminum pressure wire is fitted with a first extruded wooden pressure wire via an overlapping adhesive strip.
[0021] The outer edge of the window frame profile is fitted with an outer sealing strip, and the inner aluminum pressure line is fitted with an inner sealing strip.
[0022] The overlapping adhesive strip enables the elastic assembly of the extruded wood embossing, avoiding deformation caused by temperature and humidity.
[0023] In one possible design, an outer frame overlap strip is provided at the outer window frame;
[0024] When the window sash is closed, the outer profile of the window sash forms a seal with the outer profile of the window frame through the overlapping rubber strip on the outer side of the frame;
[0025] The overlapping adhesive strip on the outer side of the frame eliminates assembly gaps and ensures that the finish is flush.
[0026] In one possible design, a glass spacer is provided between the glass and the first and second heat insulation strips;
[0027] The glass pad controls the compression of the sealing strip to prevent potential leakage.
[0028] In one possible design, the inner profile of the window frame is fitted with a first extruded wood profile with a shape, the inner profile of the window sash is fitted with inner wood of the window sash, and the inner profile of the window mullion is fitted with a second extruded wood profile.
[0029] All wooden components are connected to the aluminum profiles using a combination of mechanical fastening and structural bonding processes;
[0030] The process addresses the problem of peeling and deformation of wooden components due to environmental influences.
[0031] In one possible design, the screen window further includes a third extruded wood profile, and the inner profile of the conversion frame, the third extruded wood profile, and the outer profile of the conversion frame are respectively fixed on the conversion frame;
[0032] The third extruded wood profile enhances the structural strength of the screen window, meeting the load-bearing requirements of large-sized windows.
[0033] In one possible design, the interior and exterior finishes of the window sash, window frame, and window mullion are flush, and the interior finishes of the window frame and window mullion are flush with the inner finish of the fixed extruded wood composite molding.
[0034] The flush structure eliminates assembly gaps caused by thermal expansion and contraction.
[0035] In one possible design, the pressure-equalizing strip is fixed to the side of the thermal insulation strip closest to the window sash;
[0036] The pressure equalization strip adjusts the pressure difference between the inside and outside to ensure smooth opening and closing of the window sash.
[0037] Beneficial Effects: This outward-opening window with a concealed screen achieves multiple performance improvements through a composite profile structure and functional integration design. The use of a double-insulated thermal break structure combined with reinforced nylon material effectively blocks heat conduction paths, significantly improving building energy efficiency. The wood veneer layer is integrated with the metal profile through a three-dimensional mechanical fixing method, solving the technical problem of traditional snap-fit installation being susceptible to environmental influences.
[0038] The integrated screen system, seamlessly integrated with the window frame, enhances the visual integrity of the building facade. Simultaneously, the screen rails meet industry standards for load-bearing capacity, satisfying the needs of large-sized windows. The glass mounting area employs a triple-seal structure with elastic pads. These improvements give this product comprehensive technical advantages in terms of thermal insulation performance, structural durability, and functional integration, making it particularly suitable for passive buildings and high-end residential projects.
