Segmented Pivot Hook Locking Element for Barrier-Free Windows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window and door locking systems are inflexible, protrude from the floor, and are not suitable for barrier-free construction, particularly for horizontal mounting, and often have only a single locking position, making them unsuitable for turn-tilt closures.
Innovation Solution
A locking element with two hook elements that can pivot into multiple positions, allowing for both locking and release configurations, enabling secure locking in various positions without protruding parts, and integrating with existing drive systems for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single locking element is used, then the device complexity is reduced, but the adaptability for multiple locking positions (closed and tilted) is insufficient
Solution Approach 1:
The locking element is segmented into two independent hook elements (first hook element and second hook element) that can operate independently. Each hook element can be pivoted into a locking position or a release position separately, enabling the system to achieve multiple locking positions (closed and tilted) without requiring entirely separate locking mechanisms for each function.
Solution Approach 2:
The locking element is designed as a universal component that performs multiple functions through its two hook elements. The same locking element structure serves both for closing position locking (via first hook element) and tilted position locking (via second hook element), making a single component multi-functional rather than requiring separate specialized components.
2Adaptability or versatility
If locking parts protrude from the floor or threshold, then the locking mechanism is simplified, but barrier-free construction is compromised
Solution Approach 1:
The protruding locking parts are extracted and replaced by hook elements that engage with locking parts recessed into the threshold or floor. The hook elements pivot within the fitting arrangement and engage with locking parts that are set back, eliminating the need for protruding components while maintaining effective locking functionality.
Solution Approach 2:
Instead of having locking parts protrude outward to engage with the locking element, the design inverts the arrangement by having locking parts recessed into the threshold/floor and having the hook elements pivot inward to engage with them. This inversion achieves barrier-free construction while maintaining secure locking.
3Adaptability or versatility
If a single locking position is provided, then the device complexity is reduced, but the suitability for turn-tilt closures is insufficient
Solution Approach 1:
The locking element is segmented into two independent hook elements that can be positioned independently. The first hook element provides locking for the closed position, while the second hook element provides locking for the tilted position, allowing the same locking element structure to support multiple closure types (turn and tilt) through segmented functionality.

AI summary
The invention relates to a fitting assembly for a window, for a door, or for the like comprising a support section, which is designed to be fastened to a main frame or wing frame of the window, the door, or the like, and comprising a bolt element, which is supported on the support section in such a way that the bolt element can be pivoted about a pivot axis. The bolt element comprises a first and a second hook element for engaging behind a closing part. According to the invention the first hook element is in a swiveled-out locking position in a first pivot position of the bolt element, the second hook element is in a swiveled-out locking position in a second pivot position of the bolt element, and both hook elements are in a swiveled-in release position in a third pivot position of the bolt element.
