Latch Insert and Spacer for Slider Window Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding window assemblies have limited latch positions, leading to potential jamming issues due to window rotation during opening and closing.
Innovation Solution
A sliding window assembly with a trim member and latch mechanism featuring a track with closely spaced latch openings, allowing for infinite position adjustment and a spacer to prevent window rotation, ensuring smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a limited number of discrete latch positions are provided, then the device complexity is reduced, but the adaptability of the window assembly is worsened
Solution Approach 1:
The latch insert is divided into multiple individual latch openings spaced along its length, each capable of receiving the latch tab at different positions. This segmentation allows the window to be latched at any of multiple discrete positions along the track, providing infinite position adjustment without requiring a complex continuous adjustment mechanism.
2Reliability
If the window is allowed to rotate during opening and closing, then the ease of operation is improved, but the reliability of the track operation is worsened due to jamming
Solution Approach 1:
A spacer member is introduced as an intermediary element between the window and the track. This spacer prevents the window from rotating during opening and closing operations by maintaining proper alignment, thereby eliminating jamming issues while preserving smooth operation. The spacer acts as a mediator that ensures the window moves linearly along the track without deviation.

AI summary
A trim assembly securable in a window frame includes a track on which a sliding window is supportable, a latch insert including a plurality of latch openings, and a latch mechanism securable to the sliding window adjacent the latch insert. The latch mechanism is displaceable between an extended position and a retracted position and includes a lever connected with a latch tab. In the extended position, the latch tab is positioned in a selected one of the latch openings. The latch mechanism is biased toward the extended position. The spacing of the latch openings provides for essentially infinite open/close positions.
