Tilt Turn Window Fitting Adjustment System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tilt window fittings face issues with misalignment between the leaf and fixed frame due to imperfections during mounting or load, making it difficult to adjust the relative position accurately and efficiently, especially for windows with restricted mounting space.
Innovation Solution
An adjustment system with a fixed and slidable section connected by an adjusting screw, featuring a gearwheel mechanism that allows for precise alignment of the leaf and fixed frame using minimal force, adaptable to different window dimensions and weights, and accessible from both sides for left- and right-opening windows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the support part of the scissor mechanism is fixedly attached to the leaf, then the structural stability is improved, but the ease of operation deteriorates because it becomes difficult to raise or lower the leaf to align it with the fixed frame
Solution Approach 1:
The support part is divided into a fixed section and a slidable section that can move relative to each other along the fitting groove. This segmentation allows the support part to maintain structural stability while enabling adjustment of the leaf position through sliding the slidable section along the groove.
Solution Approach 2:
An adjusting screw mechanism acts as an intermediary between the fixed and slidable sections. By rotating the adjusting screw, the slidable section moves along the fitting groove, providing controlled adjustment of the leaf position without requiring direct force on the fixed attachment points.
2Ease of manufacture
If conventional adjustment methods are used, then the manufacturing simplicity is maintained, but the productivity deteriorates due to time-consuming manual alignment procedures
Solution Approach 1:
The adjustment system is designed to be self-adjusting through the use of the adjusting screw mechanism. During installation, the slidable section can be easily positioned and locked at the desired location using the adjusting screw, eliminating the need for complex alignment tools or procedures and significantly reducing adjustment time.
3Manufacturing precision
If the adjustment system requires high force for adjustment, then the manufacturing precision can be maintained with simpler components, but the ease of operation deteriorates due to difficulty in making adjustments
Solution Approach 1:
The direct mechanical connection between the support part and leaf is replaced with an adjusting screw mechanism that converts rotational motion into linear displacement. This mechanical substitution allows for fine, precise adjustments with minimal force applied to the screw, enabling accurate alignment without requiring high adjustment forces.
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
Facilitates easy and accurate adjustment of the relative position between the leaf and fixed frame with reduced friction, ensuring smooth operation and compatibility with various window configurations.
Implementation Method 1
The fixed section and the slidable section of the adjustment system are connected relative to each other by an adjusting screw provided with a head and a shaft that extends axially relative to the head, whereby one of the fixed section or the slidable section encloses the head of the adjusting screw and is provided with a slot and a passage
Implementation Method 2
The adjusting screw is provided with a head with toothing which acts as a gearwheel into which a key with complementary toothing, which acts as driver gearwheel, can hook
Implementation Method 3
An objective of the invention is to provide an adjustment system that allows the relative position between leaf and fixed frame to be aligned during and after mounting, said adjustment preferably being executed such that little force is required for making the adjustment

AI summary
An adjustment system is provided with fittings of a window with a fixed frame and a leaf that can be tilted and/or turned. The fittings comprise an arm (3,34) that can be hingedly connected to the fixed frame. Characteristic is that the adjustment system is provided with a fixed section (8) that can be fixedly attached to the leaf, and a slideable section (7) that is slideable in a longitudinal direction relative to the fixed section, whereby the arm can be connected to the slidable section, and whereby the fixed section and the slidable section are connected relative to each other by an adjusting screw (24) provided with a head (26) with toothing (31) which acts as gearwheel into which a key (32) can hook, such that when rotating the key, the adjusting screw rotates, said rotation being converted into a shift of the slidable section relative to the fixed section.
