Abstract:
1. A foldable table comprising: a collapse-preventing top, said collapse-preventing top comprising a top frame, a sheet of material, and a plurality of collapse-preventing clamps, said sheet of material attached to said top frame, said top frame having a plurality of corners each of which has an inner surface, said collapse-preventing clamps attached to the inner surfaces of the four corners of said top frame by top-clamp-attaching means, respectively; a plurality of extendable-leg assemblies, each of said extendable-leg assemblies comprising a top-locking post, a leg cap, a leg, a locking-peg leaf spring, a locking peg, a locking sleeve, a leg-centering clamp, a spring-loaded extendable-leg lock, an extendable leg, and an extendable-leg foot, said top-locking post integrated into said leg cap, said top-locking post for one of said collapse-preventing clamps of said collapse-preventing top to clamp on to interlock said extendable-leg assemblies, said leg cap attached to an end of said leg, said leg having a locking-peg opening, said locking-peg leaf spring integrated into said locking peg, said locking-peg leaf spring and said locking peg inserted into said leg such that the spring force of said locking-peg leaf spring pushes said locking peg through said locking-peg opening, said locking sleeve slid on said leg such that said locking sleeve is slidably attached to said leg, said locking sleeve having a recess, said recess for said locking peg to be pressed into to secure said locking sleeve when said recess slides over said locking peg, said leg-centering clamp having a plurality of predetermined clamping jaws, said leg-centering clamp having a ring-like edge and an invisible longitudinal central axis, said clamping jaws molded to and along said ring-like edge of said leg-centering clamp such that said clamping jaws surround and lean inward toward said invisible central axis of said leg-centering clamp at a predetermined angle creating a force for said clamping jaws to center said extendable leg, said leg-centering clamp attached to another end of said leg by centering-clamp-attaching means, said spring-loaded extendable-leg lock integrated into said leg-centering clamp, said extendable leg inserted into said leg-centering clamp and said leg, said extendable leg capable of extending and retracting to adjust the height of said foldable table, said extendable leg having a plurality of extendable-leg-locking openings, each of said extendable-leg-locking openings disposed at a predetermined location on said extendable leg, each of said extendable-leg-locking openings for said extendable-leg lock to be pressed into to lock said extendable leg at a predetermined location inside said leg, said extendable-leg foot attached to an end of said extendable leg by foot-attaching means, said extendable-leg foot for stabilizing said foldable table when set on a surface; and a plurality of scissoring-arm assemblies, each of said scissoring-arm assemblies comprising a plurality of scissoring arms, a plurality of screws, and a plurality of nuts, said scissoring arms pivotally connected to one another in a scissoring configuration and to said leg caps and said locking sleeves of said extendable-leg assemblies by said screws and said nuts, respectively, such that said scissoring-arm assemblies can contract and expand to allow said foldable table to fold and unfold, respectively, said locking sleeve having a spring-loaded button and a spring-loaded latch, said spring-loaded button having a button groove, said leg further having a latch-activating opening and a latch-deactivating edge, said spring-loaded latch pivotably attached to said locking sleeve, said spring-loaded latch for rotating into said button groove and into said latch-activating opening to latch on said spring-loaded button when said spring-loaded button is pressed, said latch-deactivating edge of said latch-activating opening for rotating said spring-loaded latch out of said button groove and out of said latch-activating opening to release said spring-loaded button when said foldable table is folded, whereby, provided is said foldable table, which:
