MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611112995 A) filed by Chandigarh University on September 21, 2026, for Passive Heat-Activated Automatic Fire Escape Window System.

Inventors include Deepika Kumar; Rishabh Verma; Divya Verma; Deven; and Puneet Kumar.

The application for the patent was published on October 23, 2026, under issue no. 43/2026.

Abstract: The invention relates to a passive heat-activated automatic fire escape window 5 system. A heat-activated mechanical window assembly includes a fixed window frame (101), a movable window sash (102), a spring-loaded hinge assembly (103), a mechanical latch mechanism (104), a calibrated bi-metal thermal actuator (105), a trigger linkage arm (106), and a calibration and reset arrangement. The bi-metal actuator responds to elevated temperature by differential expansion and bending 10 and transfers mechanical displacement through the linkage arm to disengage the latch. Release of the latch permits stored energy in a preloaded spring of the hinge assembly to rotate the sash outward to a predefined opening angle, creating an emergency escape passage and smoke ventilation pathway. The activation temperature is adjustable within a predetermined range. After temperature 15 normalization, the mechanism can be manually reset by repositioning the sash, reloading the spring and re-engaging the latch.
