Abstract
An improved lockable hinge for a folding table of the type having table surface members which fold to a vertical storage position and to a horizontal usable position. The table is locked at an intermediate position when moving towards the usable position from the storage position by a pivoting lock bar which swings by gravity into a recess formed in a hinge plate on one half of the table and is jammed between the recess and a tab formed in the mating hinge plate on the other half of the table. A handle provided for the locking bar is bent away from the adjacent edges of the two table surface members and can be pivoted to withdraw the bar from the recess and around the tab as the table moves to the usable position. Release of the handle allows the locking bar to fall back into the recess engaging the other side of the tab to lock the table in the down position. A preferred embodiment allows the same hinge plate design to be used in both table halves.
