AI Technical Summary

Technical Problem

The existing built-in hinges have insufficient load-bearing capacity, a small opening distance, and are prone to causing the window sash to collide with the window frame or have excessive gaps that affect aesthetics and sealing.

Method used

A high-load-bearing and high-safety outward-opening window with built-in hinges was designed. It adopts a cross-hinged structure of slide rail, slider, long rod, middle rod, short rod and bracket. The bracket and window sash connector are eccentrically designed. Combined with plastic fasteners and axial positioning grooves, it ensures that the gap between the window sash and the window frame is reduced and the connection is stable.

Benefits of technology

It effectively reduces the gap between the window sash and the window frame, improves load-bearing capacity and safety, increases the opening distance, enhances aesthetics and sealing performance, and prevents the window sash from sagging and falling off.

Abstract

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.
