AI Technical Summary
Existing inward-opening and tilt-and-turn doors and windows require manual pulling to open after the handle is turned to unlock them. Controlling the force is not easy and can easily lead to rapid tilting inward, which may frighten the operator or people nearby. High strength requirements are required for the hardware.
Design a hinge for inward-opening and tilt-and-turn doors and windows. The hinge uses a transmission column on the transmission plate to slide in the main slide groove, which drives the tilt-and-turn linkage component to move. This allows the door and window sash to tilt inward automatically when the handle is rotated. The transmission column achieves the rotation of the linkage component through transmission grooves with different axes, avoiding external pulling.
It enables automatic tilting of door and window sashes when rotating the handle, improving the durability and safety of the hinges, avoiding impact on the profiles, providing a better user experience, and the cooperation between the locking seat and the locking block prevents accidental opening, further improving safety.
