Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window technology, specifically to an arc-shaped lift window. Background Technology
[0002] A curved lift window refers to a window whose frame or sash is curved, and the sash can be opened and closed by raising and lowering. It breaks away from the limitations of traditional windows, which are mostly straight lines and have casement or sliding opening mechanisms, combining the aesthetic design of a curved shape with the practical function of raising and lowering.
[0003] In existing curved lift window structures, because the center of gravity of the window sash is not aligned with the two sides where the lifting force is applied, the window sash tends to tilt in the direction of the curved convexity under the influence of gravity. This tilting tendency creates mutual pressure between the window frame and the sides of the window sash, resulting in excessive friction between the sash and the frame during lifting. Excessive friction not only affects the normal lifting and lowering of the window sash but also causes problems such as shaking, wear, and deformation of the profile under pressure, seriously affecting the normal use of the curved lift window. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a curved lifting window to solve the problems of excessive friction between the window frame and the window sash caused by the tilting of the window sash, which in turn affects the normal lifting and lowering of the window sash, causing shaking, wear and tear and deformation of the profile under pressure, so that the curved lifting window can operate smoothly.

The movable sash includes a top frame, a bottom frame, side frames, and a sash connecting plate. The sash connecting plate is fixedly connected to the side frames of the movable sash. The stabilizing system is used to improve the friction between the movable sash and the window frame.
[0008] Preferably, the lifting system includes a top rod base, a top rod, and a load-bearing block. The top rod base is fixedly installed on the side of the side frame, and the load-bearing block is installed on the top of the top rod.

[0014] (III) Beneficial Effects
[0015] This utility model provides an arc-shaped lifting window. It has the following beneficial effects:
[0016] 1. This curved lifting window, through the installation of a stabilization system, can effectively withstand the force of the window sash tilting in the convex direction, avoid mutual pressure between the window sash and the window frame, thereby reducing the friction between the window sash and the window frame, allowing the window sash to rise and fall smoothly, and solving the problems of shaking, wear and deformation of the profile caused by excessive friction in existing curved lifting windows.
[0017] 2. Both implementation methods of the stabilization system of this arc-shaped lifting window can reduce friction, and the structure is simple, easy to install and maintain, thus improving the performance and reliability of the arc-shaped lifting window. Attached Figure Description

[0024] Because the center of gravity of the curved lift window sash is not on the same straight line as the two sides of the lifting force point, the window sash tends to tilt in the direction of the curved convexity due to gravity. This causes mutual pressure between the window frame and the side of the window frame, resulting in excessive friction between the window sash and the window frame when the window sash is raised and lowered, which affects the raising and lowering of the window sash, causing shaking, wear and tear, and deformation of the profile under pressure, thus affecting the normal use of the curved lift window.
[0025] This utility model embodiment provides an arc-shaped lifting window, such as Figure 1-5 As shown, it includes the window frame, movable sash, lifting system, and stabilization system.
[0026] Window frame: including the top frame 11, side frames 12, and horizontal mullion, providing the basic frame structure for the entire curved lift window.
[0027] The movable fan includes an upper frame, a lower frame, a side frame 23, and a fan connecting plate 24. The fan connecting plate 24 is fixedly connected to the side frame 23 of the movable fan and is used to connect with the stabilization system to achieve stable operation of the movable fan.
[0028] The lifting system includes, but is not limited to, the embodiments described in this case. In this case, the lifting system includes a top rod base 31521, a top rod 32, and a load-bearing block 33. The top rod base 31521 is fixedly installed on the side of the side frame 12, and the load-bearing block 33 is installed on the top of the top rod 32 to support the movable fan and realize the lifting function of the movable fan.
[0029] Stable system: It has the following two implementation methods:
[0030] (I) Implementation Method 1
[0031] Assemble the window frame: Assemble the top frame 11, side frame 12, and horizontal stile according to the design requirements to form the basic frame of the window.
[0032] Install the lifting system: Fix the top rod base 31521 on the side of the side frame 12, then install the top rod 32 on the top rod base 31521, and install the load-bearing block 33 on the top of the top rod 32.
[0033] Assemble the movable fan: Assemble the upper frame, lower frame, and side frame 23 into a movable fan, and fix the fan connecting plate 24 to the side frame 23 of the movable fan.
[0034] Install the stabilization system: fix several sliders 42 to the sash connecting plate 24, and fix the linear track 41 to the side of the window frame to ensure that the sliders 42 can fit on the linear track 41 and slide.
[0035] The stabilization system includes a linear track 41 and sliders 42. Several sliders 42 are fixedly connected to the sash connecting plate 24, and the linear track 41 is fixedly connected to the side of the window frame. The sliders 42 slide on the linear track 41. During operation of the curved lift window, at least two sliders 42 are fixedly connected to the sash connecting plate 24 and simultaneously mounted on the linear track 41. When the window sash generates a force that tilts in the convex direction, this force is absorbed by the linear track 41, thus preventing mutual pressure between the window sash and the window frame. The sliders 42 are either ball-bearing sliders 42 or self-lubricating sliders 42, which effectively reduce friction caused by pressure between the linear track 41 and the sliders 42, allowing the window to operate smoothly.
[0036] Overall debugging: Install the movable sash into the window frame, adjust the lifting system and stabilization system to ensure that the movable sash can rise and fall smoothly without obvious shaking or abnormal friction during the rising and falling process.
[0037] (II) Implementation Method Two
[0038] Assemble the window frame: The window frame assembly steps are the same as in Implementation Method 1.
[0039] Install the lifting system: The installation steps are the same as those in Implementation Method 1.
[0040] Assemble the movable fan: the same as the movable fan assembly steps in Implementation Method 1.
[0041] Install the stabilization system: fix several pulleys 522 to the fan connecting plate 24, and fix the steel plate 51 to the side frame 12 on both sides of the pulleys 522.
[0042] The stabilizing system includes a steel plate 51 (not limited to any rigid material), and several sets of pulleys 522. Each set of pulleys 522 includes a base 521 and pulleys 522. The sets of pulleys 522 are fixedly connected to the sash connecting plate 24, and the steel plate 51 is fixedly connected to the side frame 12 on both sides of the sets of pulleys 522. When the curved lifting window is in operation, at least two sets of pulleys 522 are connected to the sash connecting plate 24. When the window sash generates a force that tilts in the convex direction, this force is borne by the sets of pulleys 522 and the steel plate 51, preventing the window sash and window frame from being pressed against each other. This transforms the sliding friction between the window sash and window frame into rolling friction between the pulleys 522 and the steel plate 51, effectively reducing friction and allowing the window to operate smoothly. The function of the steel plate 51 is to prevent the pulleys 522 from directly pressing against the aluminum alloy profile, which could cause profile deformation and affect the operation of the pulleys 522. Because the steel plate 51 has high hardness, it can prevent deformation due to compression.
[0043] Overall debugging: Install the movable sash into the window frame, adjust the lifting system and stabilization system to ensure that the movable sash can rise and fall smoothly, and that the rolling friction between the pulley group 522 and the steel plate 51 is normal and there are no abnormalities.
[0044] The aforementioned lifting and stabilizing systems are located on both sides of the moving fan; for ease of description, only one side is shown in the diagram.
[0045] In summary, this curved lift window, through the implementation of a stabilization system, can effectively withstand the force of the window sash tilting in the convex direction, preventing mutual pressure between the window sash and the frame. This reduces the friction between the window sash and the frame, allowing the window sash to rise and fall smoothly. It solves the problems of shaking, wear, and profile deformation caused by excessive friction in existing curved lift windows. Both implementations of the stabilization system can achieve the effect of reducing friction, and the structure is simple, easy to install and maintain, thus improving the performance and reliability of the curved lift window.
