Flush Slider Lock With Recessed Translation Stop for Easy Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locks face challenges in achieving precise locking and ease of attachment of the sole plate and slider, particularly when the bearing surface of the slider is raised relative to the base, requiring precise alignment of guide means.
Innovation Solution
The bearing surface of the slider is made flush with the base for the sole plate, and a translation stop is received in a recess of the sole plate, allowing the slider to be inserted into the guide means after the sole plate is attached to a support, with the stop being retractable or concealable to facilitate assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the bearing surface of the slider is raised relative to the base for attaching the sole plate, then the locking precision between the strike and the frame is improved, but the alignment precision of the guide means becomes more difficult to achieve
Solution Approach 1:
The translation stop is segmented into two parts: a first translation stop carried by the slider and a second translation stop carried by the sole plate. This segmentation allows the bearing surface to be raised for precise locking while the second stop on the sole plate compensates for alignment tolerances, reducing the strict alignment requirements between guide means.
Solution Approach 2:
The second translation stop on the sole plate acts as an intermediary element that compensates for misalignment between the guide means. By providing a reference point on the sole plate itself, it mediates the alignment issue and allows the raised bearing surface to function effectively without requiring precise guide means alignment.
2Ease of manufacture
If the translation stop is carried by the sole plate from the attachment base, then the slider can be inserted into the guide means before attaching the sole plate, but the assembly process becomes more complex
Solution Approach 1:
The translation stop functionality is segmented between the slider (first stop) and the sole plate (second stop). This allows the slider to be pre-assembled with the first stop, and then the sole plate with the second stop can be attached separately, simplifying the overall assembly process while maintaining the ability to insert the slider before final attachment.
3Measurement precision
If a single sole plate is used for precise locking, then the locking precision is improved, but the ease of attachment and disassembly of the slider becomes more difficult
Solution Approach 1:
The translation stop configuration enables dynamic assembly: the first translation stop on the slider allows it to be inserted into the guide means before the sole plate is fully attached. The second translation stop on the sole plate then provides the precise locking reference, combining ease of assembly with precise locking in a single sole plate design.

AI summary
A lock with a sole plate and a slider, guided in translation relative to one another by a guide between two positions, an extended position and a retracted position. The slider includes a bearing surface which extends in a sliding plane defined by the guide and an indentation relative to the bearing surface forming a translation stop in one of the two positions. The sole plate cooperates with a retractable pin of a lock carried by the slider, to lock it in the extended position and in the retracted position. The slider comprises, opposite the indentation relative to the retractable pin of the locking means, a translation stop in the extended position.
