Description
Technical Field

[0002] As supporting windows for the building's external protective structure, outward-opening windows are widely used on low floors in accordance with national regulations, especially in the southern region. Outward-opening windows have certain advantages over inward-opening windows, but they also have fatal disadvantages. Outward-opening windows are pushed to the outside of the window, and the entire fan body is suspended outside, which poses a risk of the fan body falling. For example, strong winds outside, scratches from objects, and aging of hardware over time may all cause the fan body to fall. The falling of the fan body on a slightly higher floor may injure pedestrians or objects on the lower floors, causing personal and property safety losses, with disastrous consequences. Most of the existing European standard C-slot aluminum alloy windows have good fan body anti-fall solutions, and plastic steel windows also have certain countermeasures. However, there is no corresponding solution for European standard U-slot aluminum-clad wood windows, or some solutions are not very mature, and various failures always occur, causing great trouble to customers and manufacturers.
