Multi-part Striking Plate for Sliding Door Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking systems for large sliding doors or windows face challenges in ensuring even pressure against seals due to tolerances and require multiple locking pieces, which can be time-consuming to coordinate.
Innovation Solution
A multi-part locking piece with an adjustable closing element receiving part that can be positioned relative to a fastening part using adjustment means, such as screws with cross-sectional enlargements, and a damping element to ensure reliable gripping and damping of the closing element, eliminating the need for additional fastening means and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple locking pieces are used for large sliding doors or windows, then the load on individual locking pieces is reduced and even pressure against seals is improved, but the coordination time and device complexity increase
Solution Approach 1:
The locking piece is divided into multiple independent parts: a fastening part that attaches to the beam and a closing element receiving part that can be independently adjusted. This segmentation allows each part to be optimized separately and facilitates easier installation and coordination of multiple locking pieces along the sliding door or window frame.
Solution Approach 2:
The closing element receiving part is made adjustable relative to the fastening part through adjustment means (screws with cross-sectional enlargements). This dynamic adjustability enables precise positioning of multiple locking pieces to ensure even distribution of closing impulse and uniform pressure against seals, while maintaining ease of installation.
2Adaptability or versatility
If the closing element receiving part is made adjustable, then the adaptability to different locking arrangements is improved, but the device complexity increases
Solution Approach 1:
The locking piece is divided into a fastening part and an adjustable closing element receiving part. This segmentation allows the receiving part to be independently positioned to accommodate different locking arrangements while keeping the overall structure relatively simple and modular.
Solution Approach 2:
The closing element receiving part incorporates adjustment means (screws with cross-sectional enlargements) that enable simple, tool-based adjustment of its position relative to the fastening part. This provides adaptability to different locking arrangements without requiring complex mechanisms or multiple specialized components.
3Ease of operation
If adjustment means with cross-sectional enlargements are used, then the ease of adjustment is improved, but the manufacturing complexity increases
Solution Approach 1:
The adjustment means use screws with cross-sectional enlargements that can be manually positioned and fixed at different locations along the slot. This simple mechanical design allows easy adjustment of the closing element receiving part position without requiring complex mechanisms, motors, or electronic controls, while the manufacturing complexity remains limited to standard screw and slot fabrication.
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 adaptation and precise positioning of locking pieces, ensuring uniform closure and damping of the sliding door or window, reducing the risk of jamming and improving the overall sealing efficiency by distributing the closing impulse across multiple strikers.
Implementation Method 1
a damping element (36, 37) arranged between the closing element receiving part (26) and the fastening part (25)
Implementation Method 2
The damping element can be designed, for example, as a rubber buffer or spring or other elastic element

AI summary
The component (20) has a fastening part (25) for fastening on a vertical beam. A locking-element receiving part (26) includes a slot-like retainer (27) for receiving a locking element. The locking-element receiving part is adjusted in a position relative to the fastening part by adjusting units (28, 29) e.g. screws. The receiving part is held at the fastening part by the adjusting units. The adjusting units are provided with sectional cross-section enlargements (32, 33). The cross-section enlargements are arranged in chambers (34, 35).
