A spring clip upright connection for rack shelving includes one upright with tabs and square cutouts and another upright with slots with metal spring clips. As the tabs of one upright are inserted into the slots of the other upright, the uprights are aligned and the spring metal clips open up. When the tabs are fully inserted, the clips latch into the cutouts of the slots of the other upright thereby engaging the upright sections together. This latching prevents one upright from being removed from the other upright while the slots and tabs maintain the appropriate alignment of the uprights.

A tie bar for connecting two horizontal beams includes first and second elongate walls arranged parallel to each other, and a third elongate wall arranged perpendicular to the first and second elongate walls and coupled to a lateral side of each of the first and second elongate walls. The tie bar further includes at least one pair of hook elements positioned at terminal ends of at least one of the first, second, or third elongate walls. Each of the hook elements includes a depending tab configured to be received by an elongate slot of a horizontal beam of a shelving unit. The first and second elongate walls may be top and bottom walls, respectively, the third elongate wall may be a side wall, and the at least one pair of hook elements may include first and second hook elements positioned on the second elongate wall.

A storage rack includes: a plurality of supporting pillars and a platform on which an object to be stored is to be placed. The platform includes a platform body, and a pair of attachment plates each having a plate shape. A pair of surfaces that face each other of a pair of supporting pillars are respectively provided with a pair of recessed grooves into which the pair of attachment plates are inserted. Each recessed groove includes a groove-side abutting portion that extends linearly in a direction orthogonal to the left-right direction. An outer edge of the attachment plate includes a plate-side abutting portion that is parallel with the groove-side abutting portion. The platform is fixed to the pair of supporting pillars such that the plate-side abutting portion abuts against the groove-side abutting portion.

A multi-tiered expandable filing assembly provides at least three modular trays arranged in stacked tiers and supported from two side by a pair of lateral frames. The modular trays receive, store, sort, and organize files, documents, and mail. The modular trays comprise a panel, a peripheral region, and at least one protrusion extending from the periphery. The protrusion extends from the sides of the panel and are configured to couple with the concave humps that form in the support bars of the lateral frames. The modular trays are arranged into three tiers and expanded to additional tiers of trays through constructive arrangement with the lateral frames. The lateral frames comprise a pair of legs, a top bar forming a top convex hump, and a bottom bar forming a bottom convex hump. The top and bottom convex humps from multiple assemblies can be stacked to further expand the assembly.

A shoe rock for holding organizing and holding shoes is provided. The shoe rack may include a base detachably connected to a first side rail and a second side rail, the first side rail and the second side rail extending upward from the base at an angle from 45 degrees to less than 90 degrees; and a plurality of shelves, each shelf comprising (a) a shelf platform; (b) a first joint detachably connected to the first side rail; and (c) a second joint detachably connected to the second side rail. The plurality of shelves can be at least three shelves. In addition, the present invention may include a kid for a shoe rack that includes a base, a first and second side rail, where each side rail has an angled first end that has an angle from 45 degrees to less than 90 degrees, a plurality of shelves that each has a platform, a first joint and a second joint and includes a plurality of fasteners.

As the tabs of one upright are inserted into the slots of the other upright, the uprights are aligned and the spring metal clips open up. When the tabs are fully inserted, the clips latch into the cutouts of the slots of the other upright thereby engaging the upright sections together. This latching prevents one upright from being removed from the other upright while the slots and tabs maintain the appropriate alignment of the uprights.

A storage stand, comprising at least one shelf, the shelf bounded by a perimeter, the perimeter having at least four points defining a polygon, the at least four points forming a mounting axis of rotation with respect to its adjacent clockwise point and its adjacent counter-clockwise point, and at least four mounting locations arranged within the perimeter of the at least one shelf, each of the four mounting locations having a compression centroid, each mounting location forms a compression axis of rotation with respect to its adjacent clockwise mounting location and its adjacent counterclockwise mounting location such that at least one compression axis of rotation is non-parallel to its respective mounting axis of rotation.

A shelving unit for supporting objects in a vehicle includes one or more adjustable shelves all extending transversely and horizontally between a pair of upright side panels. A rear vertical rail extends along one edge of each of the side panels and defines a plurality of slot shaped rear apertures. A front vertical rail extends along an opposite and parallel edge of each side panel. Each adjustable shelf includes a pair of shelf sides extending parallel to and adjacent the side panels. A flange extends outwardly from each of the shelf sides with a bolt attaching the flange to a front vertical rail and applying a rearward biasing force to the adjustable shelf. A rear tab extends rearwardly from each of the shelf sides and is angled laterally inwardly to engage a rear aperture in a wedging force-fit in response to the rearward biasing force.

A sleeve for a shelving unit has two halves joined together to form two support tabs extending outward from opposing sides of the sleeve as the sleeve clamps around a post having grooves into which a rib on the sleeve fits to hold the parts relative to the post. The support tabs have a retaining flange offset from the sleeve. A first collar part fastened to a shelf fits over half the sleeve and fits into that offset so that a slot in the first collar part fits over one of the support tabs to clamp them to the post and support the first collar part and shelf. The retaining flange keeps the collar part from moving off the support tab. A second collar part with a second slot may fit over the other support tabs to support a second shelf or to further clamp the sleeve to the post.
