Lock Hinges Micro: Microsat sized lock hinges for reliable and rearmable angular locking
The Lock Hinges Micro are mechanically simple, minimalistic and very solid, CNC machined, sturdy and thick with very few failure points. They are mechanically actuated by loaded compression springs that push a locking tab in place, denying movement to the hinge unless manually pulled. Using only tweezers or pins, the locking mechanism can be reset an unlimited number of times by pulling the locking tab.
The mechanical movement range is also hard-in-design specific to the hinge by mechanical modules incorporated into the geometry of the assembly, meaning the locking angle can be configured as required. These hinges are not designed to bear a significant load and must work in conjunction with sturdier hinges. They also do not impart torque on any parts and are essentially free moving until locked.
