Security Screen Mounting Rails for Window Groove Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security screen mounting systems damage windows when directly attached, voiding warranties and requiring oversized screens that are aesthetically undesirable and costly.
Innovation Solution
A mounting system using mounting rails sized to fit within the window frame's accessory groove, with a subframe and main frame attached via a hinge, allowing the screen to be pivoted and concealed fasteners for a finished look, eliminating direct attachment to the window and reducing material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security screens are directly attached to the window using mechanical fasteners, then the installation is simple and secure, but the window material is damaged and the warranty is voided
Solution Approach 1:
The patent introduces mounting rails as an intermediary component that attaches to the window frame's accessory groove rather than directly to the window sash. These rails serve as a mediator between the security screen and the window, distributing mounting forces to the frame structure while protecting the vulnerable window materials from puncture damage and warranty voiding
Solution Approach 2:
The mounting system is segmented into distinct components: mounting rails that attach to the frame, a subframe that holds the screen, and the screen itself. This segmentation allows the mounting rails to bear the structural load while the window sash remains undamaged, separating the mounting function from the window integrity
2Object-affected harmful factors
If security screens are attached to the exterior wall surrounding the window opening, then window damage is avoided, but the screens become larger than necessary and manufacturing costs increase
Solution Approach 1:
The mounting rails attached to the window frame serve as an intermediary solution that allows the security screen to be precisely sized to match the window opening. By providing a mounting structure on the frame itself, the screen can be exactly the right size without needing to extend beyond the window to attach to the wall
Solution Approach 2:
The invention utilizes the accessory groove dimension of the window frame as a mounting interface. This provides a precise locating feature that defines the screen position and size, eliminating the need for oversized screens that would be required when mounting to the wall surface
3Reliability
If security screens are attached to the exterior wall surrounding the window opening, then window warranty is preserved, but the aesthetics are compromised by hiding the window behind an oversized screen
Solution Approach 1:
The mounting rails and subframe act as intermediaries that enable precise positioning of the security screen within the window opening. This allows the screen to match the window dimensions exactly, preserving the aesthetic appearance while still protecting the window warranty through indirect attachment to the frame
Solution Approach 2:
The mounting system provides localized attachment points at the frame's accessory groove rather than requiring broad wall mounting. This localized precision mounting allows the screen to be exactly sized to the window, maintaining the window's visual prominence and aesthetic quality

AI summary
A mounting system and method for security screens for use with windows having an exterior-facing accessory groove at the outer perimeter of the window frame is disclosed. The mounting system and method according to the present invention reduces materials cost for manufacture of security screens while improving aesthetics of the installation and permitting installation of security screens either at the construction site or during window manufacture, while preserving the window manufacturer's warranty. Exemplary embodiments both with and without a subframe are described.
