Nested Locking Device for Lateral Runner Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking devices for door leaves moving in lateral runner profiles are not tamper-proof and require additional space, limiting their integration and functionality across various door positions, including closed and open positions.
Innovation Solution
A locking device comprising a stationary part within the runner profile and a movable part with a spring-loaded holding piece and beveled locking plate, allowing secure locking in any door position, integrated within the runner profiles without additional space, using a combination of mechanical or electromechanical release mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If locking devices are integrated into lateral runner profiles, then space is saved and integration is improved, but tamper-proof integration and reliability are compromised
Solution Approach 1:
The locking device is nested within the lateral runner profile structure. The locking plate is received in the runner profile, and the holding piece is received in the locking plate, creating a compact nested arrangement that integrates the locking function within the existing profile space without requiring additional external space
Solution Approach 2:
The locking device merges the locking function with the existing runner profile structure. The stationary part of the locking device is received in the runner profile, combining the guidance function of the rollers and the locking function in a single integrated structure, eliminating the need for separate locking mechanisms
2Device complexity
If locking devices are designed for closed position only, then simplicity is maintained, but versatility and adaptability are reduced
Solution Approach 1:
The holding piece is designed as a movable component that can be actuated between locked and unlocked states. The spring element provides automatic resetting functionality, allowing the holding piece to return to its original position after actuation, enabling the locking device to function in multiple positions without complex mechanisms
3Ease of manufacture
If additional space is allocated for locking devices, then integration is simplified, but space efficiency and compactness are reduced
Solution Approach 1:
The locking device is designed to work with the existing runner profile structure that serves multiple functions: guiding the door leaf movement and housing the locking mechanism. The roller elements serve both as movement guides and as part of the locking mechanism, eliminating the need for separate dedicated locking space
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 secure locking in any door position, including closed and open states, with tamper-proof integration within the runner profiles, accommodating various profile types and compensating for tolerances, while allowing easy release through mechanical or electromechanical means.
Implementation Method 1
The holding piece is spring-loaded in such a way that, in its basic position, it protrudes partially from the locking plate
