Abstract
Abstract Shelving stacks for a library or the like include lightweight pre-assembled free-standing modules which can be assembled as desired at the site. The modules are secured in assembly by rectangular top and bottom connecting frames and spaced by the frames so that the vertical frame members of the modules support slidable shelves within the modules and between the modules. The slidable shelves have a length greater than the depth of the modules. Rear wall ties and side frame ties are easily connected at the site to frame in an enclosure for the overhanging shelves and provide additional support for the modules as well as form an integrated assembly of the modules. The ties are provided in various lengths so that the shelving assembly can be arranged to provide the desired aisles and range pattern to fit the building floor plan.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
193 words
A shelving construction comprising a plurality of preassembled free-standing units each of said units including first rectangular top and bottom frames having vertically extending side faces, vertical framing members having upper and lower ends connected to said first frames proximate each of the corners thereof and located inwardly of the external periphery of said first and second frames, each of said vertical framing members including a front face and two opposed side faces, the corresponding faces of pairs of said vertical framing members on one side of said rectangular frames being parrallel; a plurality of second rectangular top and bottom connecting frames, and connecting means for connecting said second frames between the side faces of said top and bottom frames of said free-standing units interconnecting and spacing said free-standing units a distance common to the distance between the parallel side faces of said pairs of vertical framing members which lie in a plane parallel to the direction in which said spacing is measured so that shelves of the same width will fit between the free-standing units and within the free-standing units and provide an integral assembly of a plurality of shelf receiving units.
Claim 2
Dependent Claim
193 words
A shelving construction comprising a plurality of preassembled free-standing units each of said units including first rectangular top and bottom frames having vertically extending side faces, vertical framing members having upper and lower ends connected to said first frames proximate each of the corners thereof and located inwardly of the external periphery of said first and second frames, each of said vertical framing members including a front face and two opposed side faces, the corresponding faces of pairs of said vertical framing members on one side of said rectangular frames being parrallel; a plurality of second rectangular top and bottom connecting frames, and connecting means for connecting said second frames between the side faces of said top and bottom frames of said free-standing units interconnecting and spacing said free-standing units a distance common to the distance between the parallel side faces of said pairs of vertical framing members which lie in a plane parallel to the direction in which said spacing is measured so that shelves of the same width will fit between the free-standing units and within the free-standing units and provide an integral assembly of a plurality of shelf receiving units.
Claim 3
Dependent Claim
44 words
A shelving construction in accordance with claim 1 including side frame ties, and rear cross ties of varying lengths and means for connecting said ties to said units to support said units to make an integrated structure of said units and enclose said shelves.
Claim 4
Dependent Claim
31 words
A shelving construction in accordance with claim 1 wherein said vertical framing members of said free-standing units have slots in said opposed faces to receive connecting hooks on sliding shelf assemblies.
Claim 5
Dependent Claim
38 words
A shelving construction in accordance with claim 1 including rectangular end frames having four framing runs defining a rectangle and means for connecting said end frames to said second top and bottom frames to form an end unit.
Claim 6
Dependent Claim
68 words
A shelving construction in accordance with claim 1 wherein said first and second frames are constructed of angularly related material with horizontal and vertical flange portions and said vertical framing members are welded to said first frames within said vertical flanges to form an integral structure and wherein said first and second frames are provided with registrable bolt apertures and bolts securing said first and second frames together.
Claim 7
Dependent Claim
19 words
A shelving construction in accordance with claim 5 wherein said second frames have four angularly related portions welded together.
Claim 8
Dependent Claim
57 words
A shelving construction as shown in claim 1 including sliding shelves supported between said opposed side faces of said vertical framing members, said shelving assemblies having a length greater than the depth of said units and a framework of tie members connected to said free-standing units forming a skeletonized frame enclosing the overhang of said shelving assemblies.
