AI Technical Summary
Traditional casement windows and hinged barriers are vulnerable to forcible entry through the hinged side, as reinforcement strategies often compromise ease of installation, alignment, and daily operation, with anti-tamper components interfering with normal use.
A modular alignment system with a stay hinge assembly featuring an elongate base member and end portion with connector structures for attaching a locator component, allowing precise alignment of anti-tamper devices without increasing stack height, ensuring effective engagement during forced entry attempts while maintaining normal operation.
The alignment system enhances the effectiveness of anti-tamper components by ensuring precise alignment and reduced interference, allowing for smaller, more efficient anti-tamper devices that maintain operational integrity and reduce material usage.
