A storage assembly is provided with a pair of spaced apart brackets. A pair of hubs is each pivotally connected to one of the pair of spaced apart brackets. A rotary limit is connected to one of the pair of hubs and one of the pair of spaced apart brackets to limit the pair of hubs to a range of rotation relative to the pair of spaced apart brackets. A pair of bars is each connected to the pair of hubs to rotate with the pair of hubs to support and store articles upon the pair of bars.

Provided is an angle bar for shelf assembly, the angle bar including a vertical frame in which a plurality of fastening grooves is formed and a horizontal frame on which a fastening protrusion is formed, wherein the plurality of fastening grooves, each including upper and lower grooves, are formed, the lower groove has a narrower width than the upper groove, and is connected to the upper groove with an inclination portion in between, wherein the fastening protrusion includes a convex portion having an inclination surface and first and second wing portions that are formed on lateral surfaces, respectively, of the convex portion, and wherein a distance between respective end portions of the first and second wing portions is smaller than a width of the upper groove and is larger than a width of the lower groove, and the convex portion has a wider width than the lower groove.

A multi-utility table that includes a first platform a substantially a rectangular shape and four vertical members positioned at four corners of the first platform, wherein each vertical member of the four vertical members has a channel and the first platform is slidably mounted to the channels of the four vertical members. Each vertical member has an upper end and a lower end. An actuating member is operably coupled to the first platform for moving the first platform up and down along the channels. A second platform is mounted to the four vertical members near the lower end and below the first platform. A compartment is mounted to the four vertical members near the upper end.

A shelf system includes at least one modular shelf assembly including at least one shelf unit, a plurality of support posts, an adjustable foot, covers, and anchors. The at least one shelf unit, plurality of support posts, adjustable foot, covers, and anchors are, in combination, adapted to create the modular shelf assembly. Each shelf unit is adapted to receive the plurality of support posts, including one support post generally located adjacent a rear side of the shelf unit about half-way between a first and a second end of the shelf unit.

A shelf support beam for use in a shelving unit to support a shelf. The support beam includes a first end and a second end located at opposite longitudinal ends of the shelf support beam between which a structural member extends. The structural member has a C-shaped cross-section and includes a web separating a top flange that is configured to support the shelf from a bottom flange. The support beam further includes a tab located at each of the first and second ends of the structural member. Each tab includes a pair of securing fingers that are angled relative to a plane disposed perpendicular to a longitudinal axis of the shelf support beam such that each securing finger is angled inwardly toward a center of the structural member. The support beam further includes an enforcement tab formed in the web at each of the first and second ends of the structural member.

Quadrangular shelving comprising four bars with sets of four first pairs of holes, wherein the location of said sets defines different heights of the shelving for establishing the quadrangular trays, a set of quadrangular trays, wherein each tray comprises four corners and wherein each corner forms an opening and comprises a second pair of holes, the shelving comprises for each tray of the set of quadrangular trays: four plates, a pair of screws adapted to screw each plate and wherein the plate covers the opening.

A combined storage shelf, including column combinations, connection and combination fasteners, beam structures, and storage layers. The column combinations include assembly holes. A snap-fit portion of a first connection and combination fastener is snapped to an assembly hole, to fix the first connection and combination fastener to the column combination. The engagement structure of the second connection and combination fastener corresponds to the engagement structure of the first connection and combination fastener, so that the first connection and combination fastener and the second connection and combination fastener are assembled together.

A modular rack assembly includes upright support legs, two first shelf units, and a second shelf unit. Each upright support leg has two spaced-apart first hole units, and a plurality of spaced-apart second holes disposed between the first hole units. The first shelf units are connected to the upright support legs through the first hole units. The second shelf unit is engaged to the second holes of the upright support legs which are at the same height, and includes a second shelf plate formed with insertion holes, and supporting members that are engaged to the second holes at the same height and that are inserted into the insertion holes to support the second shelf plate.

The technology described herein includes a four-column shelving unit. One or more improved tie bars run between the front and rear shelf-support beams. The one or more tie bars are installed perpendicular to the shelf-support beams. The improved tie bar may take the overall form of a V-channel with a novel tri-notch connection on either end. The tri-notch connection allows the tie bar to connect with a front shelf-support beam on one end and a back shelf-support beam on the other end. The tri-notch connection includes two bottom notches and a top notch. The top notch may form a gap in the V-channel that allows the end of the tie bar to slip under a shelf-support flange on a shelf-support beam during installation. The two bottom notches are sized and shaped to receive an upward facing retention flange located on the bottom flange of the shelf-support beam.
