[0002] The up and down folding opening aluminum-clad wood window is a type of window that combines the advantages of aluminum alloy and wood. It combines the elegant appearance of aluminum-clad wood windows with the space-saving and flexible opening features of up and down folding windows. The biggest advantage of this type of window is that it saves opening space. The up and down folding window uses a folding design and does not occupy indoor space, making it particularly suitable for small-sized or space-limited rooms. When the window is fully opened, it can maximize the introduction of natural light and ventilation, improving the indoor environment quality. The up and down folding window can be opened by folding up and down, making it convenient for users to adjust the opening area of the window as needed. The up and down folding opening aluminum-clad wood windows currently used on the market have drawbacks, which can be generally divided into two categories.
