I have a need for a mechanism that acts juust like a spring (I pull, load it up, and when i let go it pulls away and returns to its normal length), but doesn't snap back like a spring.
I have experiemented with automatic door closers, but they are definatly not the answer (require too much force to pull, take too much space, too long)
Is there already a mechanism? Should i just use springs in parallel with a device like a pneumatic cylinder to control the return action? Idealy the system will only require a human to apply ~10lbs of force, and the spring/mechanism will expand ~5-10 inches, and when released, will contract with similar amount of force required to load the device
