Four Bar Mechanism Release Latch

thingiverse

This self-locking release latch ensures safety is job number one; quality and innovation are equally important. To use it effectively, attach carabiners on both ends and release by pulling a string or wire through the middle hole. The latch locks shut without a spring due to its geometry, maintaining consistent force for release regardless of load size. Inspired by sea catch release latches and Vise-Grips, this design prioritizes safety with recommendations to wear safety glasses, avoid large loads without checking material properties, and calculate maximum load. For assembly, follow instructions: 1) Make one link zero, two of the rest; 2) Drill small holes up to 3mm; 3) Use M3 nuts, bolts as pins with Loctite or rivets; 4) Add optional spring. Finish by removing sharp edges and polishing. Always prioritize safety during use. Check out this video for more information: http://www.youtube.com/watch?v=oQEopLOSnLg
