Anti-Unfolding Leg Assembly for Foldable Table

Abstract

An anti-folding leg assembly for a tabletop includes a leg frame for pivotally coupling at a bottom side of the tabletop to pivotally move between a folded position and an unfolded position, and an anti-folding arrangement including a table support having has a table coupling end adapted for pivotally coupling at the bottom side of the tabletop, and a leg support having a leg coupling end pivotally coupled at the leg frame. A pivot point is defined at a pivot connection between the table support and the leg support, and a centerline is defined between the table coupling end of the table support and the leg coupling end of the leg support when the leg frame is moved in the unfolded position, wherein the pivot point is located below the centerline when the leg frame is moved in the unfolded position.
