Abstract:
A foldable table frame comprising:a tabletop unit including front and rear frame members, each of which has a U-shaped configuration, said front frame member including parallel first lateral rods with front and rear ends and a horizontal front bar extending transversely between said front ends of said first lateral rods, said rear frame member including parallel second lateral rods with front and rear ends and a horizontal rear bar extending transversely between said rear ends of said second lateral rods, each of said front and rear frame members having a top wall, said rear ends of said first lateral rods of said front frame member being connected pivotally and respectively to said front ends of said second lateral rods of said rear frame member such that said front and rear frame members are pivotable relative to each other about a horizontal upper pivot axis parallel to said front and rear bars, each of said first and second lateral rods of said front and rear frame members having a bottom side formed with a recess, said rear end of each of said first lateral rods having an end plate which has a convex edge, said front end of each of said second lateral rods having an end piece which is pivoted to said end plate of the respective one of said first lateral rods for pivoting about said upper pivot axis and which has an abutment portion that is transverse to said end plate of the respective one of said first lateral rods, said tabletop unit being movable between an unfolded position, in which said top wall of said front frame member extends horizontally and is coplanar with said top wall of said rear frame member, and a folded position in which said first and second lateral rods are turned upright to enable said front and rear bars to move proximate to each other, said convex edge on said rear end of each of said first lateral rods moving along said abutment portion on said front end of the respective one of said second lateral rods during movement of said front and rear frame members between the folded and unfolded positions; and a leg unit which includes a pair of X-shaped leg frame portions, each of which includes first and second leg members having upper and lower ends and intermediate sections pivoted to each other about a lower pivot axis that is located below and that is parallel to said upper pivot axis, said upper ends of said first leg members of said leg frame portions being pivoted respectively to said first lateral rods of said front frame member about a horizontal front pivot axis parallel to said upper pivot axis, said upper ends of said second leg members of said leg frame portions being pivoted respectively to said second lateral rods of said rear frame member of said tabletop unit about a horizontal rear pivot axis parallel to said front pivot axis, said first and second leg members of each of said leg frame portions being movable together with said first and second lateral rods and pivoting relative to each other about said lower pivot axis for folding toward and for unfolding from each other when said tabletop unit is moved between the folded and unfolded positions, said first and second leg members of said leg frame portions extending respectively into said recesses of said first and second lateral rods of said front and rear frame members of said tabletop unit when said tabletop unit is moved to the folded position.
