Segmented Fitting Assembly for Tilt-Slide Window Jams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window and door fitting arrangements struggle to efficiently utilize a small installation space for both sliding and tilting movements of a sash, often requiring deep control elements that complicate the mechanism and increase the risk of jamming.
Innovation Solution
A fitting arrangement featuring a scissor stay with a raising arm and control arm, where the control arm has a control pin that interacts with a movable insertion part on a control element, allowing for linear tilting movement and secure stop mechanisms through form-fitting sections, enabling both sliding and tilting with minimal space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a control element is designed to be deep in the main frame plane to enable both sliding and tilting movements, then the functionality for both movements is achieved, but the installation space requirement increases and the risk of jamming increases
Solution Approach 1:
The control element is segmented into a fastening part (fixed to the frame) and a movable insertion part. This segmentation allows the insertion part to be positioned closer to the frame surface while still providing the necessary control functions for both sliding and tilting movements, thereby reducing the overall depth requirement.
Solution Approach 2:
The insertion part is designed to be movable relative to the fastening part, transitioning between a retracted position (for sliding control) and an extended position (for tilting control). This dynamic configuration allows a single control element to perform multiple functions without requiring deep installation space.
2Adaptability or versatility
If a control element is designed to be deep in the main frame plane, then both sliding and tilting movements are enabled, but the device complexity increases
Solution Approach 1:
By dividing the control element into two functional parts (fastening part and insertion part), the design simplifies the overall structure. Each part has a specific, simple function, avoiding the need for a single complex deep-mounted control element that would require multiple integrated mechanisms.
Solution Approach 2:
The movable connection between the fastening part and insertion part provides a simple yet effective mechanism for achieving dual functionality. The movement between retracted and extended positions is achieved through a straightforward mechanical connection, reducing structural complexity compared to a single deep-mounted control element.
3Adaptability or versatility
If a control element is designed to be deep in the main frame plane, then both sliding and tilting movements are enabled, but the risk of jamming increases
Solution Approach 1:
The movable insertion part can dynamically transition between retracted and extended positions based on the required operation. During sliding operations, the insertion part is retracted to avoid interference, eliminating the jamming risk that would occur with a permanently extended deep-mounted control element.
Solution Approach 2:
The segmented design allows the insertion part to be independently positioned. This independence enables the insertion part to be retracted from potential jamming positions during sliding operations while still being available for tilting control, thereby improving reliability by eliminating the permanent interference problem of deep-mounted designs.

AI summary
The invention relates to a fitting assembly for a window or door comprising a leaf that can both tilt and be detached from the fixed frame of the window or door and can slide parallel to said fixed frame. The fitting assembly (24) has a control element (46) with a fastening part (52) that can be indirectly and/or directly mounted permanently on the fixed frame. The control element (46) has an insertion part (54) which can pivot and slide relative to the fastening part (52). In an insertion position, in which a control pin of the fitting assembly can be pushed into the insertion part (54), an end section of the insertion part (54) lies preferably at least partially against the fastening part (52), such that the impact of the control pin on the insertion part (54) is conducted away into the fastening part (52) via the end section lying against said fastening part (52). The insertion part (54) can be pivoted out of its interlocking engagement with the fastening part (52), preferably by a control arm of the fitting assembly, on which arm more particularly the control pin is also located or formed, such that subsequently the insertion part (54) can slide by means of the control pin. The control element (46) can have a freewheel mechanism, by means of which the insertion part (54) can be pivoted only during the opening of the fitting assembly and not during the closing of said fitting assembly.
