Description

Technical Field

[0001] This utility model relates to the technical field of hinges, and in particular to a hinge for a top-hung window. Background Technology

[0002] Casement windows are a traditional window type, divided into inward-opening and outward-opening windows. Top-hung windows are a sub-type of casement windows, also called top-hung casement windows. Hinges are the main component connecting the window sash and frame. Referring to the utility model patent CN217001353U, entitled "A Top-Hung Hinge," existing top-hung hinges mainly include a sliding groove and a fixing rod. The sliding groove is movably connected to the fixing rod via a linkage structure. However, existing top-hung hinges lack an adjustment mechanism and are generally manually adjusted. During installation, the fixing rod of the hinge is first installed on the window sash, and then the window sash along with the hinge is manually installed onto the window frame. The sliding groove is then installed onto the window frame profile. This results in low accuracy in the adjustment position, easily causing the hinge to be installed slightly higher or lower than it should be. These subtle deviations are difficult to detect with the naked eye. Although the window sash can still be opened and closed after installation, it will not close tightly and is prone to damage.
