Multi-point lock with translating bolt and universal distributor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-point locks with translating bolts have a high number of construction parts, leading to increased complexity, cost, and inefficiency in movement distribution, making them less flexible for use with different types of cam mechanisms.
Innovation Solution
A multi-point lock design that incorporates a distributor with a rotatory movement converter, featuring an ovalized pin and a dual translation mechanism, allowing the lock to adapt to various cam types without modification, reducing the number of components and overall dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multi-point lock uses a traditional mechanism with multiple construction parts for movement distribution, then the lock can achieve secure closure at several points, but the number of components increases leading to greater complexity and higher production costs
Solution Approach 1:
The patent combines multiple movement distribution functions into a single distributor component. The distributor integrates the cam mechanism, bolt actuation, and latch control into one unified structure, eliminating the need for separate construction parts for each function while maintaining secure multi-point closure
Solution Approach 2:
The distributor is designed as a universal component that can perform multiple functions: converting rotational cam movement into linear bolt movement, controlling the main bolt position, and actuating the latch mechanism. This multi-functional design reduces the overall number of parts needed in the lock system
2Manufacturing precision
If a multi-point lock uses a complex mechanism with many construction parts, then the movement distribution can be precise, but the assembly process becomes more complex and production costs increase
Solution Approach 1:
By merging multiple precision movement distribution functions into the single distributor component, the patent reduces assembly complexity. The integrated design means fewer parts to assemble while maintaining the precision required for proper bolt and latch actuation through the unified cam mechanism
3Device complexity
If a multi-point lock uses a fixed mechanism design, then the construction can be simple, but the lock cannot adapt to different types of cam mechanisms (upright, right-projecting, left-projecting)
Solution Approach 1:
The distributor is designed as a universal component that can accommodate different cam types (upright, right-projecting, left-projecting) through its integrated cam mechanism. The design allows the same distributor structure to work with various cam orientations, providing adaptability without requiring complex modifications to the basic mechanism

AI summary
The multi-point lock (1) with translating bolt (2) comprises a rotatable distributor (3) equipped with means (4) for converting its own rotatory movement into a first reversible translation of the bolt (2) from a retracted position to a position of extraction from the case (5) of the lock (1), and into a second reversible translation of a drive lever (6) for the latch (7) of the lock (1).
