2022-08-29 (M) SkateSail Design

The wind is almost constant in South San Francisco. Before this blog, I made a kite-shaped sail that I could rapidly fold or extend. The joints were weak, and the device was heavy, so I decided to make improvements.

I considered many ideas; some were motorized, spring-loaded, elastic, cranked, or bike-mounted. The plan I want to start with is simple, with room for upgrades. The rider will hold two bars like a weight-lifter and twist them 90 degrees. Fabric will be attached to a central bar that doesn't rotate and the spinning piece. The turn will pull the material taut and catch the wind. Going the other way will collapse the triangular sails. I tried to draw a logical picture by hand, but an animation with CAD seemed the best way to demonstrate it.
