Shelving system and collapsible work bench

A shelving system for attaching to a substantially vertical surface, the system comprising:

• at least a pair of support brackets for mounting on the substantially vertical surface, each of the support brackets having a first horizontal portion and a second vertical portion, each of the first and second portions having inboard ends and outboard ends, the respective inboard ends of the first and second portions of a support bracket being permanently united together;
• a shelf platform for being supported by two or more of the support brackets, the shelf platform comprising:
• a supporting portion having a substantially planar upper surface with a front periphery and a rear periphery;
• a rear flange extending along the rear periphery of the upper surface of the supporting portion for positioning adjacent to the substantially vertical surface when the shelf platform is mounted on the support brackets mounted on the substantially vertical surface, the rear flange being oriented substantially perpendicular to the upper surface of the shelf platform;
• a front flange extending along the front periphery of the upper surface of the supporting portion, the front flange being oriented substantially perpendicular to the upper surface for extending over an outboard end of the second portion of the support brackets when the shelf platform is mounted on the support brackets;
• wherein the shelf platform is configured to be supported by the first portions of the support brackets when the second portions of the support brackets extend upwardly from the shelf platform and when the second portions extend downwardly from the shelf platform further comprising a pass-through opening in said supporting portion wherein said pass-through opening is configured to allow the support brackets to extend through the shelf platform to suspend the shelf from a higher location on the substantially vertical surface, and the pass through opening permits the support bracket to be mounted on the substantially vertical surface at a location that is relatively above the supporting portion with the bracket extending through the opening to a position below the supporting portion so that the shelf platform is configured to rest upon the second portion of the bracket.
