Double-Wing Door Lock Lifter for Variable Rebate Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking devices for double-leaf and single-leaf doors lack reliable and precise mechanisms for adjusting to door rebate clearance, complicating assembly and maintenance.
Innovation Solution
A locking device with a lifter mechanism featuring a first and second body, a length adjustment device, and a spring device, allowing for adjustable length adjustment via a screw, ensuring precise engagement and disengagement of bolts and latches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-length lifter is used in the locking device, then the structure is simple, but it cannot adapt to varying door rebate clearances
Solution Approach 1:
The lifter is designed with adjustable length through a length adjustment device that allows the lifter to be dynamically configured to match different door rebate clearances. The lifter can be extended or shortened based on the specific door configuration, transforming a static structure into a dynamic, adaptable one.
Solution Approach 2:
The length of the lifter is made variable through the length adjustment device, allowing the critical dimension to be changed to accommodate different door rebate clearances. This parameter change enables the same locking device to work with multiple door configurations without requiring different hardware components.
2Adaptability or versatility
If replacement components of different sizes are used to adjust rebate clearance, then adaptability is improved, but assembly complexity and time increase
Solution Approach 1:
Instead of requiring multiple discrete replacement components, the lifter incorporates a continuous adjustment mechanism that allows the length to be modified in-situ. This dynamic adjustment capability eliminates the need to disassemble and replace entire components, significantly reducing assembly time while maintaining adaptability.
3Adaptability or versatility
If the lifter is made length-adjustable with an adjustment screw, then adaptability to rebate clearance is improved, but the device complexity increases
Solution Approach 1:
The adjustment screw serves multiple functions: it adjusts the lifter length, provides a mechanism for securing the adjusted position, and integrates with the existing lifter structure. By making the adjustment mechanism multi-functional, the overall device complexity is minimized while achieving the desired adaptability.

AI summary
Described is a bolt and/or latch removal device (1rf) for a passive wing lock device and/or a door opener device. To adapt the removal device (100) to the door's rebate clearance, the removal device (100) is length-adjustable via an adjusting screw (80). The removal device (100) consists of a U-shaped body (10) and a T-shaped body (20), which are connected in a length-adjustable manner via the adjusting screw (80). Coil springs (51, 51) clamp the U-shaped body (10) to the T-shaped body (20) with the nut (40) of the adjusting screw (80) interposed.
