However today on the Strobist blog a very similar design by Swedish Photographer Peter Karlsson with an almost identical simpler version has put paid to the idea of patenting the concept.
So in the interest of sharing and giving back I will put my own design out there for people to copy if they want.

So the flash can go from the top down to the first leg joint.
To go lower I just pull out the lowest leg sections and let them lie on the ground.
The prototype uses hobbled together hinges made from various model plane bits and pieces.
One end of the spreader slides up the leg to bring the three legs together then the three leg sections can be pulled apart to break the stand down.
This prototype is made from carbon fibre tubes used in kite construction and will support a flash at almost two metres and weighs just 250 grams.
Collapsed it measures 69 cm.

The next version I intend to make will be a five section leg so that the collapsed stand will fit in my Pelican lighting case.
