Abstract:
A table frame for supporting a cutting machine comprising a foldable support frame and a tabletop frame,said foldable support frame comprising:two opposing pairs of leg frames each of which comprises a pair of first and second crossed legs pivotally connected together where said first and second crossed legs cross;a first connection means for supporting said two first crossed legs in parallel manner;a second connection means for supporting said two second crossed legs in parallel manner;a supporting bar affixedly connected between two top ends of said two first crossed legs; anda stopper means for supporting between said first and second crossed legs of each of said two leg frames and limiting an inclination of each of said first and second crossed legs, wherein said foldable support frame is able to selectively be unfolded to a set-up structure in which each of said leg frames is unfolded to form a rigid ""X"" structure to support said tabletop frame thereon and be folded up to an overlapping structure;said tabletop frame comprising:a hinge bar;a pair of parallel table arms each having one end perpendicularly connected to two ends of said hinge bar to form a connecting end portion of said tabletop frame which is pivotally connected between two top ends of said two second crossed legs, wherein each of said two table arms is extended from said hinge bar to form a tabletop portion and a tail portion, each of said tabletop portions of said two table arms having a length equal to a distance between said top ends of said first and second crossed legs and supporting between said hinge bar and said supporting bar, said two tail portions of said two table arms respectively extending outwardly from said supporting bar when said table frame is unfolded to said set-up structure, wherein a pair of guiders are upwardly projected near two ends of said supporting bar for guiding said two table arms to sit aside thereof so as to hold said tabletop frame in position and prevent lateral movement of said tabletop frame; anda table board affixed between said two tail portions of said two table arms;thereby, by pivotally rotating said connecting end portion along said hinge bar, said tabletop frame is able to selectively be lifted up to horizontally rest across said supporting bar and be dropped down to vertically overlap with said folded up support frame.
