Description

Technical Field

[0001] This utility model relates to the field of window technology, specifically a drift window with a four-seal structure. Background Technology

[0002] Drift windows are an innovative window and door design that combines aesthetics and practicality, with their core feature being their flexible opening mechanism. They can not only slide left and right like traditional sliding windows, opening and closing smoothly to meet space-saving and ventilation needs, but also feature a unique inward-pulling function. When the window slides inward, the sash can slightly detach from the frame, creating a drifting effect for minimal ventilation. This structure achieves smooth operation through a precise sliding rail system and hardware, ensuring free switching between sliding and inward-pulling modes. Operation is effortless and sealing performance is excellent. Drift windows not only enhance convenience and safety but also effectively improve ventilation control, making them an ideal choice for modern minimalist architecture and high-quality residences.

[0003] Chinese Patent Application No. 201821443351.X discloses a drift window mullion and a drift window. The drift window mullion includes a horizontal mullion and a vertical mullion. The horizontal mullion is horizontally installed on the window frame and includes an outer frame and an inner frame. The inner frame is located on the indoor side and has a rectangular cross-section. Limiting grooves are provided on both sides of the inner frame. One of the limiting grooves is connected to the window core through a pressing assembly. The outer frame is located on the outdoor side and has a rectangular cross-section. A first extension and a second extension extend from one side of the outer frame near the outdoor side to both sides. A sliding groove is provided on one side of the inner frame near the indoor side. The outer frame and the inner frame are connected by connectors.

[0004] Existing drift windows have poor sealing between the glass pane and the frame during use. In rainy or snowy weather, the poorly sealed gaps can easily allow rainwater to seep into the room, affecting the comfort of the living environment and the durability of the building. Therefore, there is an urgent need for a drift window with a four-layer sealing structure to improve the sealing effect. Utility Model Content

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This utility model significantly improves the overall airtightness and watertightness through a multi-level, all-round sealing design. Four independent sealing strips are set between the glass sash and the frame. The first sealing strip is movably connected to one side of the first glass sash to form a top horizontal seal. The second sealing strip is connected to the top of the first and second sub-frames and cooperates with the bottom of the first glass sash to achieve a bottom compression seal. The third sealing strip is installed on the bottom left side of the second glass sash and is movably connected to the right side of the second sub-frame to form a lateral seal. The fourth sealing strip is fixed to the bottom of the second glass sash and is movably cooperated with the top right side of the first main frame to form a bottom sliding seal. The four seals are progressively layered, effectively blocking the penetration path of air and rainwater, greatly enhancing the window's protective ability in wind and rain environments, while reducing noise transmission and energy consumption.

[0022] 2. This utility model further optimizes the sealing and assembly stability at key connection points. The first, second, third, and fourth sealing elements are respectively set on the opposite sides of the main frame, sub-frame, and glass sash, forming a three-dimensional sealing system between the frames. The third sealing element has a hollow heat insulation cavity inside, which improves the overall heat insulation performance. All sealing elements are installed by engaging with the corresponding slots on the profiles through clips. For example, the connection between the first sealing strip and the first sub-frame has an inverted snap-fit ​​corner, and the connection between the third and fourth sealing strips and the second glass sash also adopts the same structure, ensuring that the sealing strips are firmly embedded and not easy to fall off. The entire window body is made of aluminum alloy, and the profile has a hollow cavity inside, which combines the advantages of strength, heat insulation, and lightweight, so that the drift window maintains excellent sealing performance, durability, and operational stability during long-term use.
