Abstract
Abstract Modular knockdown shelving is disclosed having vertical spaced supports with a plurality of recessed slots for the engagement of adjustable hidden brackets that support the ends of shelf members whereby the brackets lock to the shelves and the supports by the load thereon. A plurality of shelves can be variously positioned in vertically spaced relationship between and upon a pair of upright supports and can be readily adjusted, one to the other, to provide the desired spacing between the shelves. The shelves have a plane top surface with a rolled flange edge and are provided with a bottom panel, also having a flanged edge which interlocks with the rolled flange and also locks to the brackets. In one embodiment, the brackets fit within the rolled flanges of the shelf ends and serve both to interlock the top and bottom panels and rigidly support the shelf in load-supporting relationship.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
156 words
Knockdown shelving including: a. a shelf member, a bracket member and an upright support member; b. said shelf member having spaced top and bottom walls extending over a portion of the width and length of the shelf; c. an aperture in said shelf opening to the space between said spaced walls; d. said bracket member having a hook end with an upwardly turned tab extending above said top wall and a support arm extending downwardly below the bottom wall; e. said support member having a vertical recessed intermediate Wall with a slot therethrough at the shelf level; f. whereby in the assembled condition said hook end of said support arm is adapted to engage the slot in said intermediate wall of said support member with said tab against the backside of said wall above said slot and said support arm extending through said aperture into the space between the top and bottom walls of said shelf.
Claim 2
Dependent Claim
156 words
Knockdown shelving including: a. a shelf member, a bracket member and an upright support member; b. said shelf member having spaced top and bottom walls extending over a portion of the width and length of the shelf; c. an aperture in said shelf opening to the space between said spaced walls; d. said bracket member having a hook end with an upwardly turned tab extending above said top wall and a support arm extending downwardly below the bottom wall; e. said support member having a vertical recessed intermediate Wall with a slot therethrough at the shelf level; f. whereby in the assembled condition said hook end of said support arm is adapted to engage the slot in said intermediate wall of said support member with said tab against the backside of said wall above said slot and said support arm extending through said aperture into the space between the top and bottom walls of said shelf.
Claim 3
Dependent Claim
67 words
Knockdown shelving in accordance with claim 1 in which: a. said shelf member has a depending flange member at one side and an aperture in the bottom wall contiguous to said flange; b. said bracket member has a notch in the top edge of said support arm whereby said flange member is engaged within the notch of said support arm in the assembled condition of said shelf.
Claim 4
Dependent Claim
41 words
Knockdown shelving in accordance with claim 1 in which: a. the top and bottom walls of said shelf member have a box channel open at one end; and b. said support arm is adapted to press fit into said box channel.
Claim 5
Dependent Claim
142 words
Knockdown shelving in accordance with claim 1 in which: a. the top wall of said shelf member has a depending box flange along opposite edges and a depending upwardly turned reverse flange along a remaining edge to form a stiffened top panel; b. said bottom wall of said shelf member has an upstanding flange along opposite edges and a downwardly turned reverse flange along a remaining edge to form a reinforcing bottom panel; c. the effective perimeter of said flanges of said bottom panel being less than the perimeter of said flanges of said top panel whereby the former is nestable within the latter in which nested condition the inner wall of said box flanges engage against the upstanding flanges of said bottom panel and the reverse flange of said top panel engages under the downwardly turned flange of said bottom panel.
Claim 6
Dependent Claim
51 words
Knockdown shelving in accordance with claim 4 in which: a. said top and bottom panels are rectangular in planar configuration the sides of which are defined by the respective flanges of said opposite edges of each and the ends are defined by said respective reverse flanges and downwardly turned reverse flanges.
Claim 7
Dependent Claim
44 words
Knockdown shelving in accordance with claim 4 in which: a. said bottom panel has an opening in one of said opposite edges to receive said support member; and b. said support arm is press-fitted between said top and bottom walls of said shelf member.
Claim 8
Dependent Claim
101 words
Knockdown shelving in accordance with claim 2 in which: a. the hook end of said bracket member has a lower buttress edge facing away from from the support arm; b. an upwardly depending tab is provided at the top edge of said hook; c. said tab having a buttress edge facing toward said support arm; d. said respective buttress edges are vertically offset from each other an amount substantially equal to the thickness of said intermediate wall of said support member; and e. a notch is provided in the top edge of said support arm to receive said depending flange member.
Claim 9
Dependent Claim
116 words
Knockdown shelving in accordance with claim 7 in which: a. said support member has a second wall outward from said recessed wall; b. said notch in said support arm has an edge spaced from said lower buttress edge of said hook member an amount substantially equal to the space between said recessed wall and said second outer wall; c. said tab having a buttress edge facing toward said support arm; d. said respective buttress edges are vertically offset from each other an amount substantially equal to the thickness of said intermediate wall of said support member; and e. a notch is provided in the top edge of said support arm to receive said depending flange member.
Claim 10
Dependent Claim
59 words
Knockdown shelving in accordance with claim 7 in which: a. said support member has a second wall outward from said recessed wall; and b. said notch in said support arm has an edge spaced from said lower buttress edge of said hook member an amount substantially equal to the space beTween said recessed wall and said second outer wall.
