US Patent 7490562 Folding table tennis table

A folding table tennis table comprising a support, two table tops that are movable relative to the support between a horizontal position and a vertical position, each table top co-operating with the support to form a structure of configuration that is reversibly foldable between an unfolded state corresponding to the horizontal position of the table top and a folded state corresponding to the vertical position of the table top, which structure includes a retractable lock to lock it in at least one of the two states. The foldable structure includes an abutment that engages when its configuration comes close to a configuration corresponding to a locked state, thereby opposing reversibility in that configuration.
