This invention discloses a built-in hinge for a high-load-bearing, high-safety outward-opening window and a method for installing the window sash. The built-in hinge includes a slide rail, a slider, a long rod, a middle rod, a short rod, and a support arm. One end of the long rod is hinged to the slide rail, and one end of the middle rod and one end of the short rod are slidably connected to the slide rail. The middle rod and the short rod are cross-hinged. The other end of the middle rod is connected to the long rod, and the other ends of the short rod and the long rod are connected to the support arm. The hinge points A and B between the middle rod and the long and short rods, and the hinge points C and D between the support arm and the short and long rods, form a quadrilateral ABCD. The connection point on the support arm that fixes the window sash is eccentrically inward towards the line connecting the hinge points CD. During the opening and closing process of the hinge of this invention, the gap between the frame and sash profiles is reduced from the conventional 7mm or more to 4mm, preventing collision between the window sash profile and the window frame profile. This shortens the distance between the two profiles, improving the aesthetics of the window while also enhancing the overall thermal insulation, sealing, and safety of the window.

2.1 The aim is a swiveling windowsill so that flower pots and other decorative items do not have to be removed when ventilating and do not have to be put back after ventilating. It should also be possible to attach it to window sashes that only have a narrow contact surface in front of the glass. It can be used on both sashes of double-leaf windows and can also be used on sashes with and without handles. 2.2 The downward vertical force is not absorbed by devices attached to the bearing surface in front of the glass, but by devices positioned on the upper edge of the window sash. 2.3 The pivoting window sills can also be used for window sashes with any narrow contact surface in front of the glass. The production of modern windows with three and even four panes results in window sashes with increasingly narrow contact surfaces, rendering conventional pivoting window sills unusable. Furthermore, the pivoting window sills can also be used for both sashes of double-sash windows, with or without a handle, and regardless of whether a fixed mullion is installed between the sashes.

A locking mechanism for a diagonal tie rod in an outward-opening, top-hung hardware system is disclosed.
