Front-Access Lateral Adjustment Hinge for UPVC Windows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of door and window edges, particularly in UPVC constructions, necessitates a hinge design that allows for lateral adjustment of the sash section relative to the frame section, which is challenging due to the need for the attachment point to be moved further from the edge, affecting the design and installation process.
Innovation Solution
A hinge with lateral adjustment means operable from the front face of the sash section, incorporating a rack and pinion mechanism, and locking mechanisms using friction plates to secure the sash and frame sections, allowing for adjustable and lockable positions to accommodate varying door and window profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the attachment point of the sash section is moved further from the edge of the door/window, then the hinge can accommodate complex door/window profiles, but the design and installation process becomes more challenging
Solution Approach 1:
The hinge incorporates a lateral adjustment mechanism that allows the sash section to be dynamically repositioned relative to the frame section. The adjustment means include a rack and pinion arrangement with a handle, enabling the sash section to move laterally between multiple positions to accommodate different door/window profile complexities while maintaining a relatively simple base hinge design
2Adaptability or versatility
If the attachment point of the sash section is moved further from the edge of the door/window, then the hinge can accommodate complex door/window profiles, but the installation process becomes more challenging
Solution Approach 1:
The lateral adjustment mechanism is designed to be operated from the front face of the sash section, allowing installers to easily adjust the position during installation without requiring complex jigs or specialized tools. The rack and pinion mechanism with an externally accessible handle enables intuitive self-adjustment, and the locking mechanism automatically secures the selected position, making the installation process straightforward despite the increased adaptability
3Ease of operation
If a lateral adjustment mechanism is added to the hinge, then the sash section can be adjusted laterally with respect to the frame section, but the hinge structure becomes more complex
Solution Approach 1:
The lateral adjustment mechanism is integrated into the existing hinge structure such that the same components serve multiple functions. The rack and pinion mechanism not only provides lateral adjustment but also inherently guides the movement and provides mechanical advantage. The locking mechanism serves both to secure the adjusted position and to maintain the structural integrity of the hinge assembly, thereby adding adjustment capability without proportionally increasing overall structural complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy and precise adjustment of the sash section relative to the frame section, simplifying installation by allowing adjustment from the front face, reducing the need for complex jigs, and ensuring secure locking, thus facilitating the fitting of sash sections in complex rebate features without predrilled holes.
Implementation Method 1
The lateral adjustment means may include a rack and pinion adjustment. A rack may be provided on the hinge plate, preferably in an opening, or slot, therein. A pinion may be provided on the attachment section.
Implementation Method 2
The locking means includes cooperating friction plates, which are ridged plates, which are adapted to deter lateral movement.
