AI Technical Summary
In existing five-bar hinges, the weight of the window sash is mainly borne by the connecting rods that are connected to its window frame, resulting in uneven stress and easy damage.
Design a hinge structure in which the second and fourth links are connected to the fifth link to distribute the weight of the window to the second and fourth links. The first link is connected to the fourth link to further distribute the force to the first link. The third link is connected to the fourth link to distribute the force to the third link. Finally, the force is distributed to all links through the mounting components to achieve uniform force distribution.
By distributing the force evenly, the risk of hinge damage is reduced, and the stability and flexibility of the hinge are improved.
