Description

Technical Field

[0001] This utility model relates to the field of window sash protection technology, specifically to anti-collision corner protectors for inward-opening casement windows. Background Technology

[0002] Inward-opening windows refer to windows that open horizontally inwards when opened. This type of window does not occupy outdoor space and is suitable for rooms with limited outdoor space. The advantages of inward-opening windows include good ventilation, good sealing and safety. A certain amount of space is required to open the window for easy operation. Inward-opening window anti-collision corner guards are a type of protective device installed on inward-opening windows. Their main function is to prevent injury to people due to accidental collisions during the opening or closing of the window.

[0003] Currently, the corners of inward-opening casement windows are cut at 45 degrees and then assembled at 90 degrees. This results in sharp edges and corners at the joints in the middle of the casement, lacking protective components. This makes inward-opening casement windows a significant safety hazard to children or cleaning staff when opened. Furthermore, some inward-opening casement windows are only protected by attaching protective covers, which affect the airtightness when the window is closed, preventing the window from being completely sealed.
