Description

Technical Field

[0001] This utility model relates to the field of building door and window technology, specifically to a five-bar linkage structure for an outward-opening window friction hinge. Background Technology

[0002] Outward-opening window friction hinges, also known as sliding hinges, are a type of hardware specifically designed for outward-opening windows. They control the opening and closing trajectory of the window sash through friction, balancing support, safety, and ease of use. Their core function is to achieve stable support and positioning of the window sash through mechanical structure design, while adjusting the friction force during opening and closing to improve safety and user experience. As the core load-bearing component of the window sash, the friction hinge can bear the entire weight of the window sash and distributes the force through a multi-point support design to prevent the window sash from sagging or falling off.

[0003] However, in actual installation and use, the contact surface of the internal support arm of the outward-opening window friction hinge structure is small, the support arm structure is weak, and the overall strength of the hinge is poor. Under repeated opening and closing, the overall stability of the hinge is insufficient in the long-term use.

[0004] Now, a novel five-bar friction hinge structure for outward-opening windows is proposed to address the aforementioned shortcomings. Utility Model Content
