Telescoping Window Support With Pivoting Crossbar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable supports for double hung windows do not adequately address the need for a device that can pivot with respect to the support member and be extended and secured in multiple positions without damaging the window, limiting users' ability to clean windows without using their arms or risking damage to the hinged connection.
Innovation Solution
An adjustable support comprising a base, a first tubular member with a friction lock, a second tubular member in telescoping engagement, and a transverse member that can pivot on the second tubular member, allowing the second member to be secured at various positions and the transverse member to pivot, distributing pressure evenly and accommodating different window heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user supports the bottom pane with their arm to prevent damage during cleaning, then the window is protected from excessive torque, but the user cannot use both arms for cleaning and experiences fatigue
Solution Approach 1:
The patent introduces a support device as an intermediary between the user and the window pane. This device includes a support member with a support surface that contacts the bottom pane, allowing the user to rest the pane on the device rather than supporting it with their arm. The support member is positioned to provide structural assistance without interfering with the hinged connection, thus protecting the window while freeing both of the user's hands for cleaning.
2Ease of operation
If a fixed support device is used to hold the window pane, then the user's hands are freed for cleaning, but the device cannot accommodate different window heights
Solution Approach 1:
The patent implements a telescoping mechanism in the support device where the support member can extend and retract to different lengths. This dynamic adjustment capability allows the device to adapt to various window heights while maintaining its function of supporting the pane. The telescoping feature enables the support surface to be positioned at the appropriate height for different window configurations, providing both hands-free operation and versatility.
3Stability of the object's composition
If a support device applies pressure to the bottom pane to prevent movement, then the pane is stabilized during cleaning, but excessive pressure could damage the glass or frame
Solution Approach 1:
The patent incorporates a friction-based locking mechanism that allows for adjustable pressure application. The support member can be positioned to apply just enough frictional force to stabilize the pane during cleaning operations. The friction lock mechanism enables fine-tuning of the pressure parameter, ensuring sufficient stabilization without exceeding the threshold that would cause damage to the glass or frame. This parameter adjustment capability balances stability requirements with damage prevention.

Function Achieved in This Case
Enables users to clean double hung windows with both hands, preventing excessive torque on the hinged connection and allowing for secure positioning at various heights, thus preventing damage to the window while ensuring effective cleaning.
Implementation Method 1
the first friction lock telescopingly secures the second tubular member within the first tubular member
Implementation Method 2
the second friction lock pivotably secures the transverse member to the second tubular member
