Window Vent Stop with Flexible Side Engagement Pieces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window vent stops are difficult to install and require specific sash stile thickness and recess sizes, leading to inefficiencies and the need for multiple purchases due to fit issues.
Innovation Solution
The use of flexible side engagement pieces in the vent stop design allows for installation in various sash stile thicknesses and recess sizes, featuring a housing with a tumbler mechanism and spring bias for secure operation, enabling compatibility with different window types and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional rigid vent stops with fixed dimensions are used, then manufacturing precision can be maintained, but adaptability to different sash stile thicknesses and recess sizes is poor
Solution Approach 1:
The vent stop incorporates flexible side engagement pieces that can dynamically adjust their shape and position to accommodate varying sash stile thicknesses. These flexible pieces bend and conform to the specific dimensions of each installation location, allowing a single vent stop design to adapt to multiple window types and sizes while maintaining secure engagement.
2Ease of operation
If vent stops are designed for specific sash stile thicknesses, then manufacturing precision is improved, but ease of operation and installation is reduced due to fit issues
Solution Approach 1:
The vent stop is designed with universal applicability through flexible side engagement pieces that can be installed in various sash stile thicknesses and recess sizes. This multi-functional design allows a single vent stop model to serve multiple window types (double hung, single hung, sliding windows, and doors) without requiring custom manufacturing for each application, thereby simplifying installation while maintaining secure fit.
3Productivity
If multiple vent stops are purchased to accommodate different window sizes, then adaptability is improved, but loss of time and productivity are increased due to multiple purchases and installations
Solution Approach 1:
The flexible side engagement pieces enable a single vent stop design to universally accommodate different window sizes and types. This eliminates the need to purchase multiple vent stops for different applications, reducing material waste, lowering costs, and minimizing installation time while maintaining secure fit across various window configurations.

Function Achieved in This Case
This solution simplifies the installation process and ensures reliable operation by accommodating a range of sash stile dimensions, reducing the need for multiple purchases and enhancing security and ventilation control.
Implementation Method 1
a spring means for biasing said tumbler into the extended position
Implementation Method 2
at least one side engagement piece which is flexible and bendable with the shape of the recess cut into the sash stile

AI summary
A window vent stop for use in a sliding sash window or a sliding door assembly. The vent stop has a housing adapted to be disposed in a recess in the non-movable sash member. This housing includes a cavity with a bottom plate therein. The tumbler has at least one pivot for pivotally securing the tumbler to the housing for movement between an extended position, to prevent movement of the sliding member and a retracted position, to allow movement of the sliding member. Also within the housing the tumbler is formed with a plastic member for selectively biasing the tumbler. The housing has one or more flexible members extending from the end walls of the housing that secure the housing to an opening in a window sash when a portion of the window sash is positioned between the underside of a lip on the housing and the flexible member.
