AI Technical Summary
There is room for improvement in the existing roof window lifting devices in terms of balancing window weight and operating force, especially in the opening and closing of windows on sloping roofs, where the existing devices have high design flexibility and material consumption.
The lifting device design integrates the first and second guide rails with the side frame components. The guide rails serve as guides and reinforcing elements for the carriage. Combined with the lifting arm, push arm, and carriage arm, the connection points are adjusted by the adjustment system to adapt to different roof slopes, reducing the use of individual reinforcing elements and materials.
It achieves reduced material consumption while maintaining functionality, makes the lifting device simpler and easier to install, and effectively balances the weight of the window. The window can be opened up to 50 degrees, especially suitable for a 45-degree opening angle, improving design flexibility and ease of operation.
