Flags are a bit boring on a windless day.
I have proposed before various approaches to blowing air across them but today’s invention is a different approach.
A motor unit could be raised or lowered on a conventional flagpole.
On the top of this, a crank (grey) would be rotated. Attached to this is a shaft composed of many hinges, each free to rotate only a few degrees about a vertical axis.
The hinges would be embedded within the upper edge of the flag.
In this way, the motor could be slowly rotated, allowing the hinges to support the flag whilst also simulating the effect of wind-driven flapping.
