Abstract
Abstract A free standing shelving system including a plurality of shelves and a plurality of spindles for supporting the shelves, some of the shelves being arranged in endwise adjacent relation whereby the shelving system has some abutting shelf ends and some free shelf ends. The shelves each have like corner openings in all four corners with one spindle at each corner opening at the free end of the shelves and one spindle at the contiguous corner openings in endwise abutting shelves. The spindles are disposed in endwise aligned relation with their axes at the virtual corners of the shelves and the spindles have end faces on their adjacent ends that overlap the shelves adjacent the corner openings. Adapter members extend between the adjacent end faces on the spindle members externally of the shelf and a threaded connector extends axially of the spindles and in substantial alignment with the virtual corners of the shelves for connecting associated ones of the upper and lower spindle members to their respective adapter member and to the shelf. The adapter members include a lateral portion that underlies the shelf and has means thereon for engaging the shelf inwardly of the corner opening to inhibit relative movement between the adapter member and shelf in a direction laterally of the shelf.

Claim 5
Dependent Claim
72 words
A free standing shelving system according to claim 1 wherein adapter members at the free ends of the shelves comprise corner adapter members having upright shelf-edge engaging faces angularly spaced 90° apart about the axis of the threaded connector means, and the adapter members at the abutting ends of the shelves are side adapter members having upright shelf-edge engaging faces angularly spaced apart 180° about the axis of the threaded connector means.
Claim 6
Dependent Claim
