Four Bar Mechanism Release Latch

Safety is job number one, quality is also job number one, as is innovation. Sometimes you might be working on a project and need a way to release something heavy without risking it falling on you. This self-locking release latch can be attached to carabiners at both ends and released by pulling on a string or wire through the middle hole. If the material being held fits perfectly, the latch will lock shut without a spring. Due to its design, the force needed to release the latch is largely independent of the load being held, which prevents it from jamming. This latch was inspired by the sea catch release latch and Vise-Grips. Always wear your safety glasses. Never use this device for large loads without checking the material properties and calculating the maximum load. Always design with a reasonable factor of safety. Be smart, stay safe. http://www.youtube.com/watch?v=oQEopLOSnLg
