Foldable wheeled stand

摘要

The stand incorporates two pairs of wheels and a support pole carried from a central pivot member. The stand is collapsible from an upright orientation in which all wheels are floor-engaging to a folded orientation in which the wheels lie closely alongside the support pole. The wheels are carried on wheel support elements which in turn are connected to a central pivot member. Folding and collapsing actions are synchronized by control arms that extend between the support pole and wheel support elements.
