Fitting Component with Angled Leg for Window Groove Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fitting arrangements for windows and doors, particularly those using frontal assembly, face difficulties in assembly and maintenance due to components easily falling out of the C-shaped groove, and require a large number of components, making replacement and repair challenging.
Innovation Solution
A fitting arrangement where a first fitting part, such as a drive rod, can be pivoted and lowered into the C-shaped groove, engaging with its edges to prevent falling, and a second fitting part is attached using an angled leg for secure assembly and force transmission, with a locking device for secure positioning and easy disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If frontal mounting of fitting components is used, then assembly speed and ease of installation are improved, but components easily fall out of the C-shaped groove during installation
Solution Approach 1:
A fitting component serves as an intermediary element that bridges the gap between the C-shaped groove and the hardware mechanism. The fitting component has a specific design with edge regions that engage the groove legs and a base with a leg that rests on the groove bottom, preventing it from falling out while enabling frontal mounting.
Solution Approach 2:
The fitting component is segmented into distinct functional parts: edge regions for engaging the groove legs, a base for structural support, and a leg extending from the base to rest on the groove bottom. This segmentation allows each part to perform its specific function in preventing the component from falling out.
2Reliability
If multiple components are used for frontal mounting, then secure assembly is achieved, but device complexity and number of components increase
Solution Approach 1:
Multiple functional features are merged into a single fitting component design. The edge regions, base, and leg are integrated into one component that simultaneously provides engagement with the groove, structural support, and prevention of falling out, eliminating the need for multiple separate components.
Solution Approach 2:
The fitting component performs multiple functions: it engages the C-shaped groove through its edge regions, provides structural support through its base, prevents falling out through its leg, and serves as a mounting platform for the hardware mechanism. This multi-functionality reduces the overall number of components needed.
3Ease of operation
If hardware components are inserted frontally into the groove, then on-site installation is simplified, but components can pivot out again at their upper end
Solution Approach 1:
The leg extending from the base of the fitting component performs a preliminary anti-action by resting on the bottom of the C-shaped groove before the component is fully inserted. This prevents the component from pivoting out again at its upper end by providing a stop that counteracts the pivoting motion.
4Reliability
If locking devices are added for secure positioning, then component retention is improved, but ease of replacement and repair is reduced
Solution Approach 1:
The fitting component design incorporates dynamic characteristics that allow it to be easily inserted and secured during installation, while the same design features enable easy removal and replacement. The engagement with the groove legs and the rest on the groove bottom provide secure positioning during use, but the overall design allows for straightforward removal when needed for replacement or repair.

AI summary
The invention relates to a fitting component (8) of a fitting (5) for a sash (2) of a window or door, for insertion into a C-shaped groove (7) in the rebate of a frame profile (6) of the sash (2), comprising a base body (10) having a front (11) and a back (12), wherein the base body (10) has on opposite sides a first edge region (14) for engaging behind one groove leg (18) of the C-shaped groove (7) and a second edge region (15) for engaging behind another groove leg (19) of the C-shaped groove (7). According to the invention, a leg (20), in particular an angled leg, is provided on the front side of the base body (10) adjoining the second edge region (15) to form a groove (21) for inserting a further fitting component (9).
