Foldable table with reinforcing unit

Abstract

A foldable table includes a tabletop made of U-PVC material with solid structure, a reinforcing unit and two leg frames. The reinforcing unit is provided at the bottom side of the tabletop for evenly distributing and supporting a downward loading force on the tabletop. The reinforcing unit further includes two longitudinal reinforcing members for increasing the rigidity of the tabletop. The two leg frames are foldably supported at the bottom side of the tabletop to fold between an unfolded position and a folded position.
