Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
344 words
A modular shelf comprising: at least two spaced apart vertical support assemblies, each of said vertical support assemblies comprising elongated upper and lower horizontal members spaced vertically apart from one another, a first pair of vertical members spaced apart from one another and embracing said upper and lower horizontal members therebetween, a second pair of spaced apart vertical members embracing said upper and lower horizontal members therebetween, said upper horizontal member being operatively secured to said first and second pairs of members at a point spaced downwardly from the upper ends of said vertical members so as to form a U-shaped channel with said upper ends of said vertical members, said lower horizontal member being operatively secured to said first and second pairs of vertical members so as to form an inverted U-shaped channel with said lower ends of said vertical members, said first pair of vertical members being spaced horizontally from said second pair of vertical members so as to combine with said upper and lower horizontal members to create a rectangular configuration, an upper horizontal support assembly extending between said spaced apart vertical support assemblies, said upper horizontal support assembly having two downwardly presented horizontal ribs, each of which is in registered alignment with one of said horizontal members of said vertical support assemblies, said downwardly presented ribs being slidably retentively fitted within said U-shaped channels of said vertical support assemblies; a lower horizontal support assembly extending between said spaced apart vertical assemblies, said lower horizontal support assembly having upwardly presented horizontal ribs, each of which is in registered alignment below one of said lower horizontal members of said vertical support assemblies, said upwardly presented ribs being slidably retentively embraced within said inverted U-shaped channels of said vertical support assemblies, said upper and lower horizontal assemblies each having a plurality of elongated slats extending transversely to said ribs, said horizontal ribs being secured to said slats at points spaced inwardly from the opposite ends of said slats, all of said slats being spaced inwardly from the opposite ends of said horizontal ribs.
Claim 2
Dependent Claim
344 words
A modular shelf comprising: at least two spaced apart vertical support assemblies, each of said vertical support assemblies comprising elongated upper and lower horizontal members spaced vertically apart from one another, a first pair of vertical members spaced apart from one another and embracing said upper and lower horizontal members therebetween, a second pair of spaced apart vertical members embracing said upper and lower horizontal members therebetween, said upper horizontal member being operatively secured to said first and second pairs of members at a point spaced downwardly from the upper ends of said vertical members so as to form a U-shaped channel with said upper ends of said vertical members, said lower horizontal member being operatively secured to said first and second pairs of vertical members so as to form an inverted U-shaped channel with said lower ends of said vertical members, said first pair of vertical members being spaced horizontally from said second pair of vertical members so as to combine with said upper and lower horizontal members to create a rectangular configuration, an upper horizontal support assembly extending between said spaced apart vertical support assemblies, said upper horizontal support assembly having two downwardly presented horizontal ribs, each of which is in registered alignment with one of said horizontal members of said vertical support assemblies, said downwardly presented ribs being slidably retentively fitted within said U-shaped channels of said vertical support assemblies; a lower horizontal support assembly extending between said spaced apart vertical assemblies, said lower horizontal support assembly having upwardly presented horizontal ribs, each of which is in registered alignment below one of said lower horizontal members of said vertical support assemblies, said upwardly presented ribs being slidably retentively embraced within said inverted U-shaped channels of said vertical support assemblies, said upper and lower horizontal assemblies each having a plurality of elongated slats extending transversely to said ribs, said horizontal ribs being secured to said slats at points spaced inwardly from the opposite ends of said slats, all of said slats being spaced inwardly from the opposite ends of said horizontal ribs.
Claim 3
Dependent Claim
33 words
A modular shelf according to claim 1 wherein said upper and lower horizontal assemblies are identical in construction each having a pair of upwardly presented ribs and a pair of downwardly presented ribs.
Claim 4
Dependent Claim
30 words
A modular shelf according to claim 2 wherein said pair of upwardly presented horizontal ribs and said pair of downwardly presented horizontal ribs are in vertical spaced apart registered alignment.
Claim 5
Dependent Claim
25 words
A modular shelf according to claim 3 wherein said slats extend transversely to said ribs through the space between said upwardly and downwardly presented ribs.
Claim 6
Dependent Claim
63 words
A modular shelf according to claim 4 wherein a third horizontal assembly identical in construction to said first mentioned horizontal assemblies is operatively attached to one of said first mentioned horizontal assemblies, said ends of at least two of said slats of said one horizontal assembly protruding between said spaced apart ends of said upper and lower ribs of said third horizontal assembly.
Claim 7
Dependent Claim
27 words
A modular shelf according to claim 7 wherein said slats of said third assembly are transversely oriented with respect to said slats of said one horizontal assembly.
