Abstract

Abstract A knockdown table formed of a cardboard blank which has been adapted by means of a plurality of fold lines and score lines in such a way that when the blank is folded along said fold lines a table having an imperforate top will be defined thereby, the score lines defining removable sections which, when removed, are effective to form the legs of the table, and are further adapted to be delineated into corner locking and supporting members which will underlie and act as support for the resulting standing table structure.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 228 words
A foldably constructible table comprising a construction blank fabricated of cardboard having an elongated, rectangular shape, at least two transversely oriented first and second fold lines in said blank delineating two leg-forming panels at opposite ends thereof and an intermediate imperforate tabletop panel, at least two longitudinally oriented third and fourth fold lines respectively located in said blank adjacent each longitudinal edge thereof delineating corner-forming flaps foldable along each of said fold lines into cooperating positions with said leg-forming and tabletop panels so as to form corners along each of the longitudinal extents of said panels, a cooperating pair of outwardly diverging fold lines in said blank at each of the four intersections of said first, second, third and fourth fold lines and delineating a separate one of four triangular tuck-in flaps operatively effective to be projected to the interior of the volume bounded by said table following the folding construction thereof, and in each said leg-forming panel a shaped centrally located score line delineating a removable section effective to form legs therein upon said removal therefrom, at least one said removable section being delineated into plural tabs each having regular sides and each having a notch therein of an extent adapted to accommodate one said inwardly projected tuck-in flap so as to maintain said inwardly projected position thereof, whereby said table is foldably constructible from said blank.
Claim 2
Dependent Claim 228 words
A foldably constructible table comprising a construction blank fabricated of cardboard having an elongated, rectangular shape, at least two transversely oriented first and second fold lines in said blank delineating two leg-forming panels at opposite ends thereof and an intermediate imperforate tabletop panel, at least two longitudinally oriented third and fourth fold lines respectively located in said blank adjacent each longitudinal edge thereof delineating corner-forming flaps foldable along each of said fold lines into cooperating positions with said leg-forming and tabletop panels so as to form corners along each of the longitudinal extents of said panels, a cooperating pair of outwardly diverging fold lines in said blank at each of the four intersections of said first, second, third and fourth fold lines and delineating a separate one of four triangular tuck-in flaps operatively effective to be projected to the interior of the volume bounded by said table following the folding construction thereof, and in each said leg-forming panel a shaped centrally located score line delineating a removable section effective to form legs therein upon said removal therefrom, at least one said removable section being delineated into plural tabs each having regular sides and each having a notch therein of an extent adapted to accommodate one said inwardly projected tuck-in flap so as to maintain said inwardly projected position thereof, whereby said table is foldably constructible from said blank.
Claim 3
Dependent Claim 35 words
A blank for a foldably constructible table as defined in claim 1 wherein each of said pair of outwardly diverging lines terminates in slots extending inwardly into said construction blank from the longitudinal edges thereof.
