Vehicle window glass breaking system and method of use

The present invention is a vehicle window glass (i.e., vehicle door window) breaking system. The system integrates a glass-breaking mechanism with a door handle that offers manual or automatic activation. A concealed button near the handle facilitates manual activation and automatic activation employs sensors autonomously triggered or actuated by water buoyancy or collision impact. The system features a pin (i.e., cylindrical pin) affixed to the edge of the window glass (i.e., vehicle door window), with a driving cable passing through an aperture in the pin. A cable jacket encases the cable, guiding its movement and transmitting pulling force efficiently. When activated, the pin (i.e., cylindrical pin) rotates, generating a shearing force that breaks the glass. The glass installation base anchors the cable jacket, stabilizing the system and distributing stresses.

Method and apparatus for manufacturing a glass blade with a cutting edge

PendingUS20260022051A1Glass severing apparatusBreak the glassStructural engineering
The present invention provides a method for manufacturing blades with a cutting edge from glass by subjecting a strip glass to a controlled breaking force. Before breaking the glass is scored to create a line of weakness at which the break is made. The glass is broken by striking the glass with a breaking force that causes the glass on either side of the score line to pivot away from one another. This controlled breaking of the glass strip creates a broken off portion of glass that has a sharp cutting edge. The present invention also provides an apparatus that creates glass blades in accordance with the method.
