Abstract
Abstract The invention provides a modular shelving unit comprising at least two upright members and at least two shelf elements which engage oppositely spaced upright members to form a shelving structure. The component upright members and shelf elements are made of a latticework, preferably of welded wire, which is secured at two opposite edges in support beams. The support beams of the upright members provide vertical structure for the unit, and the support beams of the shelf elements provide structure therefor and means for connecting the shelf elements to the upright elements.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
186 words
A modular shelving unit comprising: at least two upright members, each member comprising a latticework having prongs along two opposing edges thereof, said prongs being alternately bent at approximately right angles to the plane of the latticework, and a first support beam for each edge of the latticework having bent prongs, each said first beam being formed to define a longitudinal channel of C-shaped cross section so that the bent edge prongs of the latticework may be inserted and fixed within said longitudinal channel, said first support beams providing upright structural components for the unit; and at least two shelf elements, each element comprising a latticework having prongs along two opposing edges thereof, and a second support beam for each latticework edge having prongs, each said second beam being formed to define a longitudinal channel of U-shaped cross section so that the edge prongs of the latticework may be inserted and fixed within said channel, said second beams having means at each end for engaging the latticework of an upright member, said shelf elements being engagable with oppositely spaced upright members to form a shelving unit.
Claim 2
Dependent Claim
186 words
A modular shelving unit comprising: at least two upright members, each member comprising a latticework having prongs along two opposing edges thereof, said prongs being alternately bent at approximately right angles to the plane of the latticework, and a first support beam for each edge of the latticework having bent prongs, each said first beam being formed to define a longitudinal channel of C-shaped cross section so that the bent edge prongs of the latticework may be inserted and fixed within said longitudinal channel, said first support beams providing upright structural components for the unit; and at least two shelf elements, each element comprising a latticework having prongs along two opposing edges thereof, and a second support beam for each latticework edge having prongs, each said second beam being formed to define a longitudinal channel of U-shaped cross section so that the edge prongs of the latticework may be inserted and fixed within said channel, said second beams having means at each end for engaging the latticework of an upright member, said shelf elements being engagable with oppositely spaced upright members to form a shelving unit.
