Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
134 words
A rack for storing items comprising in combination: a shelf member having pairs of opposed leg receptors positioned in spaced relationship about the perimeter of said shelf member, said shelf member having an upraised stop lip located proximate one edge for facilitation of positioning of such stored items on said shelf member; and leg members for mating with said receptors to extend in opposed directions from said shelf member, thereby providing for stacking of said shelf members to form a vertical rack with said leg members interspersed between said shelf members and wherein said shelf members include a plurality of knockout plugs in the surface of said shelf members, wherein said knockout plugs are removed from said shelf members and mated with any unused leg receptors thereby sealing any of said unused leg receptors.
Claim 2
Dependent Claim
134 words
A rack for storing items comprising in combination: a shelf member having pairs of opposed leg receptors positioned in spaced relationship about the perimeter of said shelf member, said shelf member having an upraised stop lip located proximate one edge for facilitation of positioning of such stored items on said shelf member; and leg members for mating with said receptors to extend in opposed directions from said shelf member, thereby providing for stacking of said shelf members to form a vertical rack with said leg members interspersed between said shelf members and wherein said shelf members include a plurality of knockout plugs in the surface of said shelf members, wherein said knockout plugs are removed from said shelf members and mated with any unused leg receptors thereby sealing any of said unused leg receptors.
Claim 3
Dependent Claim
19 words
The storage rack of claim 1, wherein said leg members mate with said leg receptors through a friction fit.
Claim 4
Dependent Claim
24 words
The storage rack of claim 1, further including a means for limiting the position in which items may be stored on said shelving units.
Claim 5
Dependent Claim
110 words
A storage rack comprising in combination: a four-sided shelf member having opposed leg receptors positioned at each of the four corners of said shelf member; leg members for mating with said leg receptors to extend in opposed directions from said shelf members thereby providing for stacking of said shelf members to form a vertical rack with said leg members interjoined between said shelf members, said leg members being designed to frictionally mate and lock with said receptors; and a plurality of knockout members spaced through such shelf member, wherein said knockout members removed from said shelf member and mated with any unused leg receptors thereby sealing said unused leg receptors.
Claim 6
Dependent Claim
110 words
A storage rack comprising in combination: a four-sided shelf member having opposed leg receptors positioned at each of the four corners of said shelf member; leg members for mating with said leg receptors to extend in opposed directions from said shelf members thereby providing for stacking of said shelf members to form a vertical rack with said leg members interjoined between said shelf members, said leg members being designed to frictionally mate and lock with said receptors; and a plurality of knockout members spaced through such shelf member, wherein said knockout members removed from said shelf member and mated with any unused leg receptors thereby sealing said unused leg receptors.
