Safety Locking Device with Spherical Latch for Misalignment Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Safety locking devices face challenges in accommodating different types of safety doors and compensating for misalignments, as they typically require specific alignment and direction for secure locking.
Innovation Solution
A safety locking device with a locking element that can be secured in various aligned positions within a continuous angular range of at least 90°, allowing flexible insertion and locking directions, and featuring a latch with a spherical or ball-shaped end for secure engagement and a spring-loaded mechanism for automatic locking, along with chamfered edges and elastic elements for misalignment compensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a safety locking device requires specific alignment and direction for secure locking, then the locking mechanism is simple and reliable, but it cannot accommodate different types of safety doors and compensates poorly for misalignments
Solution Approach 1:
The receiving section is designed with a spherical or ball-shaped end that can engage with the locking element from multiple directions (at least 90° angular range), allowing the same locking device to work with different door types including sliding doors, swing doors, and hoods without requiring different locking mechanisms
Solution Approach 2:
The spherical or ball-shaped end of the latch enables multi-directional engagement with the locking element, providing geometric flexibility to accommodate misalignments and different insertion directions while maintaining a relatively simple locking mechanism structure
2Reliability
If the locking element requires precise alignment in a single direction, then the locking mechanism is straightforward, but it cannot compensate for misalignments of the safety door
Solution Approach 1:
The spherical or ball-shaped end of the latch can engage with the locking element from multiple directions within at least 90°, providing geometric flexibility to accommodate misalignments while ensuring reliable locking
Solution Approach 2:
The locking device allows the locking element to be secured in differently aligned positions forming a continuous angular range of at least 90°, changing the angular parameter from a single fixed direction to a multi-directional range, thereby compensating for misalignments while maintaining secure locking

AI summary
The present invention relates to a safety locking device for interlocking a safety door, having a movable part designed for being fastened to a moving part of the safety door and having a locking element, and a stationary part designed for being fastened to a non-moving part of the safety door. The stationary part includes a receiving section having an opening for the reception of the locking element, where the locking element can be inserted into the receiving section from different insertion directions when the locking element is aligned in the insertion direction. The stationary part includes a latch selectively movable from a locking position into a release position.
