Abstract
Abstract An adjustable rack for books is provided which includes a pair of supports aligned in parallel spaced relationship and a pair of end plaques removably mounted on the supports. Each end plaque lies in a plane normal to the plane of the supports. One end plaque is mounted in a fixed position on a corresponding pair of ends of the supports, while the other end plaque is movably mounted on the supports relative thereto. The longitudinal body of each support includes symmetrically aligned radially extending ribs, and each support terminates in discrete pairs of legs having outwardly turned feet, which releasably engage a plaque on the support. A pair of corresponding ends of the respective supports are gusseted for the purpose of releasably fixing the position of one of the end plaques on the supports.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
351 words
An adjustable rack assembly for books or like items comprising first and second supports alignable in parallel spaced relationship; and corresponding first and second end plaques removably mountable on first and second supports, respectively; said first and second end plaques being mountable on each of said first and second supports each extending substantially normal to a plane through said first and second supports; each of said first and second end plaques comprising a substantially planar plastic web having first and second major planar surfaces, each in a plane substantially parallel to its respective web, and each web including corresponding first and second channel members having respective first and second channels therein, said first and second supports being introduceable into said channels for mounting each of said first and second end plaques on said first and second supports; said first and second supports including first means cooperable with said first and second channel members on said first and second end plaques for releasably engaging opposite ends of said first and second supports, respectively, to said first and second end plaques, said means comprising respective discrete pairs of resilient legs mounted on each end of each of said first and second supports, and corresponding pairs of feet emergent from said legs, said feet being aligned and emergent at relative normals to said legs, each of said discrete pairs of legs having a slot defined therebetween, said respective feet of each discrete pair having a distance therebetween which exceeds the height of each of said channels, said respective discrete pairs of legs having a flex characteristic under a linearly applied pressure for introduction of said discrete pairs of resilient legs through a respective channel in said end plaques, each of said feet having a cammed surface corresponding to a cam profile of said channel; and said first and second supports including second means cooperable with said first means for fixing the position of said first end plaque on said first and second supports, said second end plaque being slidable on said first and second supports and telescopable thereon relative to said first end plaque.
Claim 2
Dependent Claim
351 words
An adjustable rack assembly for books or like items comprising first and second supports alignable in parallel spaced relationship; and corresponding first and second end plaques removably mountable on first and second supports, respectively; said first and second end plaques being mountable on each of said first and second supports each extending substantially normal to a plane through said first and second supports; each of said first and second end plaques comprising a substantially planar plastic web having first and second major planar surfaces, each in a plane substantially parallel to its respective web, and each web including corresponding first and second channel members having respective first and second channels therein, said first and second supports being introduceable into said channels for mounting each of said first and second end plaques on said first and second supports; said first and second supports including first means cooperable with said first and second channel members on said first and second end plaques for releasably engaging opposite ends of said first and second supports, respectively, to said first and second end plaques, said means comprising respective discrete pairs of resilient legs mounted on each end of each of said first and second supports, and corresponding pairs of feet emergent from said legs, said feet being aligned and emergent at relative normals to said legs, each of said discrete pairs of legs having a slot defined therebetween, said respective feet of each discrete pair having a distance therebetween which exceeds the height of each of said channels, said respective discrete pairs of legs having a flex characteristic under a linearly applied pressure for introduction of said discrete pairs of resilient legs through a respective channel in said end plaques, each of said feet having a cammed surface corresponding to a cam profile of said channel; and said first and second supports including second means cooperable with said first means for fixing the position of said first end plaque on said first and second supports, said second end plaque being slidable on said first and second supports and telescopable thereon relative to said first end plaque.
Claim 3
Dependent Claim
39 words
The adjustable rack assembly as claimed in claim 1, said second means comprising first and second gussets mounted respectively on said first and second supports proximate corresponding ends thereof in specific predetermined spaced relation relative to said corresponding ends.
Claim 4
Dependent Claim
39 words
The adjustable rack assembly as claimed in claim 1, said first and second end plaques including corresponding pluralities of symmetrically arranged support bearings mounted, respectively, on said second major surface of each of said webs for reinforcing said webs.
Claim 5
Dependent Claim
45 words
The adjustable rack assembly as claimed in claim 1, each of said first and second end plaques including a respective lip flange formed substantially at a normal to said webs, said lip flanges extending at least along the bottom edges of each of said webs.
Claim 6
Dependent Claim
27 words
The adjustable rack assembly as claimed in claim 1, each of said first and second supports including plural load bearing surfaces, and corresponding plural support bearing surfaces.
Claim 7
Dependent Claim
48 words
The adjustable rack assembly as claimed in claim 1, said first and second supports each comprising corresponding elongated first and second webs of resilient plastic materials including plural radially extending pairs of support bearings formed by the intersection of substantially planar webs at relative normals to each other.
