Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
145 words
A table frame assembly for supporting a table top, comprising four tubular frame members each of square cross-sectional shape, arranged in a rectangular configuration, four stay brackets, means for securing the frame members and further means for securing the stay brackets to the under surface of the table top, four end brackets each arranged diagonally with respect to the frame members and secured to the under surface of the table top, each having a pair of outstanding spigots receiving adjacent ends of, and retaining, two respective said frame members, each end bracket also having a hinge pin extending diagonally with respect to the frame members, four legs each hinged to a respective said end bracket by its said hinge pin, and four articulated links each connected at one end to a respective said leg and at its other end to a respective said stay bracket.
Claim 2
Dependent Claim
145 words
A table frame assembly for supporting a table top, comprising four tubular frame members each of square cross-sectional shape, arranged in a rectangular configuration, four stay brackets, means for securing the frame members and further means for securing the stay brackets to the under surface of the table top, four end brackets each arranged diagonally with respect to the frame members and secured to the under surface of the table top, each having a pair of outstanding spigots receiving adjacent ends of, and retaining, two respective said frame members, each end bracket also having a hinge pin extending diagonally with respect to the frame members, four legs each hinged to a respective said end bracket by its said hinge pin, and four articulated links each connected at one end to a respective said leg and at its other end to a respective said stay bracket.
Claim 3
Dependent Claim
67 words
A table frame assembly according to claim 1 wherein each said end bracket comprises two groups of half bearings in a single moulding, one group being outer half bearings which engage respective portions of the hinge pin surface and the other group being inner half bearings which are staggered with respect to said outer half bearings, and which engage other respective portions of the hinge pin surface.
Claim 4
Dependent Claim
52 words
A table frame assembly according to claim 1 wherein each said leg comprises a pair of tubular leg members each of square cross-sectional shape which converge from a respective said end bracket to a foot, and which have apertures extending therethrough, the walls of which pivotally bear on a said hinge pin.
Claim 5
Dependent Claim
108 words
A table frame assembly according to claim 1 wherein each said stay bracket comprises a base, pivot rib and a retaining rib, a spigot outstanding from the pivot rib spaced laterally from the retaining rib, an aperture in an end of a respective articulated link, said lateral spacing between the pivot rib and the retaining rib being such that said articulated rib is positionable over the spigot and the walls of said link aperture then pivotally bear on the outstanding spigot, but upon inclining of said link, it is then held captive between the pivot rib and the retaining rib and retained on the spigot by those ribs.
Claim 6
Dependent Claim
49 words
A table frame assembly according to claim 4 wherein each said stay bracket comprises a wedging rib the ends of which engage and releasably retain the tubular leg members of a respective said leg when that leg is folded to lie adjacent the under surface of a table top.
Claim 7
Dependent Claim
59 words
A table frame assembly according to claim 1 wherein each said articulated link has two portions interconnected by a hinge pin, and an abutment pad also retained by said hinge pin and arranged to bear against the under surface of a table top when its respective leg is folded to lie adjacent the under surface of a table top.
Claim 8
Dependent Claim
108 words
A table frame assembly according to claim 4 wherein each said stay bracket comprises a base, pivot rib and a retaining rib, a spigot outstanding from the pivot rib spaced laterally from the retaining rib, an aperture in an end of a respective artiuclated link, said lateral spacing between the pivot rib and the retaining rib being such that said articulated rib is positionable over the spigot and the walls of said link aperture then pivotally bear on the outstanding spigot, but upon inclining of said link, it is then held captive between the pivot rib and the retaining rib and retained on the spigot by those ribs.
Claim 9
Dependent Claim
49 words
A table frame assembly according to claim 5 wherein each said stay brackets comprises a wedging rib the ends of which engage and releasably retain the tubular leg members of a respective said leg when that leg is folded to lie adjacent the under surface of the table top.
