Abstract:
A foldable table frame for supporting a tabletop thereon, comprising:a foldable table frame body;two pairs of frame top joints pivotally connected to a top of said foldable table frame body; anda pair of table support apparatus, each comprising a pair of table support arms, two tabletop support arm holders and a vertical support arm pillar for supporting said two tabletop support arm holders respectively, each of said table support arms having an outward end and an inward end connected with a tabletop support arm stopper;wherein said four table support arms further have four outward end points adjacent to said four outward end thereof, which are pivotally connected to four upper surfaces of said four frame top joints respectively, and that each of said four frame top joints has an indentation at least as wide as each of said tabletop support arms for allowing said respective tabletop support arm to pivot downward when said foldable table frame is folded up,wherein said two inward ends of each pair of said table support arms are respectively extended inwardly to slidably connect through one of said tabletop support arm holders of said table support apparatus, wherein each pair of said table support arms slidably rest horizontally in parallel with each other, wherein two bottom ends of said two support arm pillars are pivotally connected to said foldable table frame body,wherein said two tabletop support arm holders of each of said two pairs of tabletop support arm holders are pivotally connected to two sides of a top end of said respective support arm pillar respectively so as to situate a top end of said respective support arm between said respective pair of tabletop support arm holders in such a manner as to allow said four tabletop support arms sliding through said four tabletop support arm holders respectively;wherein in order to fold up said foldable table frame, said four tabletop support arms are folded downwards by downwardly rotating said two pairs of tabletop support arm holders towards said inward ends of said tabletop support arms respectively, so that each of said two pairs of said tabletop support arm holders rotates in opposite directions and said four tabletop support arms slide inwardly and downwardly to a downward position as said foldable table frame is collapsed,wherein in order to unfold said foldable table frame, each of said tabletop support arms slides outward from said downward position to a horizontal position, and each of said two pairs of tabletop support arm holders pivotally rotate in opposite directions towards said outward ends of said two respective tabletop support arms respectively, so as to allow said four tabletop support arms to move upwardly and outwardly through said four tabletop support arm holders respectively until said four tabletop support arm stoppers are stopped by said four tabletop support arm holders respectively.
