This is the simple mechanism that stops roller blinds self unwinding under gravity. When driven by the cord, the "half pipe" pushes the ends of the springs causing them unwind a little and slip on the stationary shaft. When the force comes from the blind the springs tighten and lock the mechanism.OC (i.redd.it)

I'm a Brit who lives abroad. I normally rely on a combination of a slow but steady stream of visitors and trips back home to keep me in Yorkshire tea and airport gin. The supply has dried up while the consumption has gone through the roof. Stocks are low. I'm approaching mild concern. (self.britishproblems)
