Locking Wheel Chock
"I built it because I needed a way to keep my airplane stationary inside a hangar. It was hard to keep wood chocks from sliding along the hangar's epoxy-coated floor."
Made from wood and metal, the patented wheel chock consists of two parts. One part contains a gear with a stub shaft locking mechanism extending up out of it. The other part is a "rack gear" that the gear housing rides along. The stub shaft has a small pin through it.
To use the chock you place both parts alongside the tire, then use a plastic tubular handle equipped with a J-hook at the bottom to move both chock parts against the tire at the same time.
Clark says he's looking for a manufacturer.
