Today’s invention is a washing line which detects the onset of rain and withdraws its washing into a waterproof housing.
The rightmost post would hold a spring loaded washing line reel and a relative humidity sensor.
When rain threatens the clothing, each of the (yellow and orange) items is withdrawn inside a tall shelter (dark blue).
The line wraps around a rotating, motor-driven, spiral rail which keeps the clothing from being crushed together.
if the weaher were bad enough, a small fan might be activated to dry the washing whist still hanging in the shelter.
