Abstract
Abstract This invention relates to a readily assembleable and adjustable shelving system. Briefly, it comprises vertical corner support posts; paired separable bracket members adapted to inter-engage about a respective support post to form a corner sleeve assembly; and a shelf provided with corner retainers bearing a recess revealing an inner surface complimentary of approxmately one-half of the circumference of a sleeve assembly. The posts and sleeve assemblies are adjustably positioned through a locking means comprising a coupled protrusion and depression provided on their contiguously abutting surfaces; while the shelf corner retainers and sleeve assemblies are secured through substantially longitudinal sets of extending ribs and recessed grooves wedgingly meshed on their contiguously abutting surfaces. Through this construction and alignment of elements, downward forces on the shelf are redirected radially inward through the assembly towards each respective support post so as to stabilize the shelf assembly.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
135 words
An adjustable shelving system comprising: vertical corner support posts; corner sleeve assemblies, each comprising a pair of separable bracket members inter-engaged about a respective support post; each assembly and respective support post being adjustably positioned through a locking means comprising a coupled protrusion and depression provided on their contiguously abutting surfaces; a shelf provided with corner retainers, each retainer having a recess revealing an inner surface complimentary of one-half the circumference of each assembly; each retainer being secured to both bracket members of an assembly by means of substantially longitudinal sets of complimentary extending ribs and recessed grooves opposingly positioned on the inner surface of the retainer and the exterior surface of the bracket member respectively, said retainer and assembly being wedgingly meshed to redirect downward longitudinal force radially inward towards a respective support post.
Claim 2
Dependent Claim
135 words
An adjustable shelving system comprising: vertical corner support posts; corner sleeve assemblies, each comprising a pair of separable bracket members inter-engaged about a respective support post; each assembly and respective support post being adjustably positioned through a locking means comprising a coupled protrusion and depression provided on their contiguously abutting surfaces; a shelf provided with corner retainers, each retainer having a recess revealing an inner surface complimentary of one-half the circumference of each assembly; each retainer being secured to both bracket members of an assembly by means of substantially longitudinal sets of complimentary extending ribs and recessed grooves opposingly positioned on the inner surface of the retainer and the exterior surface of the bracket member respectively, said retainer and assembly being wedgingly meshed to redirect downward longitudinal force radially inward towards a respective support post.
Claim 3
Dependent Claim
26 words
A system according to claim 1, wherein each protrusion is a transverse rib lying in a plane normal to the longitudinal axis of the support post.
Claim 4
Dependent Claim
39 words
The shelving system of claim 2, wherein each support post surface is provided with a first longitudinal strip extending substantially its length, said strip marking an eccentricity in the cross-sectional perimeter of the post to rotationally orient the assembly.
Claim 5
Dependent Claim
22 words
The shelving system of claim 3, wherein each support post surface is provided with a second longitudinal strip opposite the first strip.
Claim 6
Dependent Claim
34 words
The shelving system of claim 4, wherein each support post is substantially circular in cross-section over the majority of its perimeter and the longitudinal orienting strips are parallel planar surface indentations in said perimeter.
Claim 7
Dependent Claim
22 words
The shelving system of claim 5, wherein the locking means for the assembly and post is located in the longitudinal orienting strips.
Claim 8
Dependent Claim
31 words
A system according to claim 2, wherein the transverse rib extends from the inner surface of one bracket member to the inner surface of the other inter-engaged member of the assembly.
Claim 9
Dependent Claim
15 words
A shelving system according to claim 7, wherein the vertical support posts are essentially tubular.
Claim 10
Dependent Claim
14 words
A shelving system according to claim 1, wherein the sleeve assembly is essentially tubular.
Claim 11
Dependent Claim
25 words
A shelving system according to claim 9, wherein the inner surface of the corner retainer forms an arch complimentary with the configuration of the assembly.
Claim 12
Dependent Claim
37 words
A shelving system according to claim 1, wherein the outer surface of the assembly is provided with longitudinal grooves commencing at the upper end of said assembly, the depth of said grooves decreasing downward from said end.
Claim 13
Dependent Claim
29 words
A shelving system according to claim 1, wherein the inner surface of the retainer is provided with longitudinal ribs and the extension of said ribs decreasing down said surface.
Claim 14
Dependent Claim
16 words
The shelving system of claim 1, wherein the cross-sectional perimeter of each support pole is elliptical.
Claim 15
Dependent Claim
30 words
A shelving system according to claim 1, wherein opposing corner retainers of two shelves are fixed to each assembly around common corner support posts to form a composite shelving system.
