Abstract
Abstract A shelving structure is made up of angular corner posts having prongs on which U-shaped struts are hung to tie the posts together, the slits in the struts receiving depending flanges of the shelves so that the are supported and serve to strengthen the struts. The corner posts may be replaced by special posts so that separate module units may be united. Related prongs are provided to yield horizontal or slanting shelves.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
101 words
A shelving structure comprising upright corner posts which, in cross-section, have two legs at right angles in each other, each leg having therealong on its inner face upwardly pointing prongs; struts which are U-shaped in cross-section and thereby present upwardly opening lengthwise slits, said struts having holes at their ends in their under sides which open up into said slits; said holes receiving said prongs to thereby support the struts, said struts being arranged in an encircling arrangement to thereby support and tie the post together, and shelves having depending flanges which are positioned in said slits to retain the shelves.
Claim 2
Dependent Claim
101 words
A shelving structure comprising upright corner posts which, in cross-section, have two legs at right angles in each other, each leg having therealong on its inner face upwardly pointing prongs; struts which are U-shaped in cross-section and thereby present upwardly opening lengthwise slits, said struts having holes at their ends in their under sides which open up into said slits; said holes receiving said prongs to thereby support the struts, said struts being arranged in an encircling arrangement to thereby support and tie the post together, and shelves having depending flanges which are positioned in said slits to retain the shelves.
Claim 3
Dependent Claim
15 words
The shelving structure of claim 1 in which the prongs lie in individual horizontal planes.
Claim 4
Dependent Claim
37 words
The shelving structure of claim 1 in which a strut is on prongs in one horizontal plane and the opposite strut is on prongs in another horizontal plane whereby the shelf they support slants from the horizontal.
Claim 5
Dependent Claim
38 words
The shelving structure of claim 3 in which the other struts for the shelf slant between said horizontal planes and have holes spaced further apart to accommodate the greater distance between the prongs which support said other struts.
Claim 6
Dependent Claim
40 words
The shelving structure of claim 1 in which the slit in each strut is widened out at its deep end and said flange has a ridge along its lower edge to lie in said widened portion and form an interlock.
Claim 7
Dependent Claim
37 words
The shelving structure of claim 3 in which a backing plate rests on said slanting shelf and a strut is held on prongs at the upper part of the backing plate for said plate to bear against.
Claim 8
Dependent Claim
55 words
The shelving structure of claim 3 in which a backing plate rests on said slanting shelf, a strut is held on prongs at the rear of the backing plate and a backing brace which has a flange portion positioned in the slit of said strut and a body portion against which the backing plate bears.
