An foldable shelf includes: a foldable support body, where the support body can be switched between a folded state and an unfolded state; several layer plates, where the several layer plates fit with the support body to form a storage space in the unfolded state and reduce a volume of the foldable shelf in the folded state; and a fixing mechanism for securing the layer plates to the support body, where the fixing mechanism includes: a first fastener, where an outer surface of the first fastener is provided with at least one protrusion; and a second fastener, where the second fastener is provided with a groove for accommodating the first fastener; where a side wall of the groove is provided with a through hole matching the protrusion.

Provided is prefabricated furniture and, more particularly, to a prefabricated shelf (angle) having assembly holes and assembly protrusions for assembling frames together, the frames being more firmly assembled as a pressing protrusion portion protrudes from a narrow portion of an assembly hole so that an assembly protrusion is forcibly fitted by the pressing protrusion part. The prefabricated shelf includes a first frame in which a pair of assembly holes, each having a wide portion and a narrow portion, are arranged symmetrically, and a second frame in which a pair of assembly protrusions, corresponding to the assembly holes and each protruding to fit into the narrow portion, are arranged symmetrically, wherein the narrow portion includes a pressing protrusion portion configured to protrude from a first end thereof and press the assembly protrusion to a second side thereof to force the assembly protrusion into place.

A hang harvesting system includes a plurality of stackable pods each including a platform, and a plurality of support shafts extending vertically from the platform. Each of the support shafts defines a plurality of notches configured for suspending a horizontal bar from the support shafts. Top ends of the support shafts of one pod are configured to support a platform of another pod thereon.

A combined type shelf includes parallel-rod side frames, inter-frame connectors, storage layers and horizontal constraint frames. The parallel-rod side frame includes a first vertical bar, a second vertical bar and a horizontal bar. The inter-frame connector includes a connector body, two lateral plates, a hole and lower interference parts. The storage layer is disposed between two horizontal constraint frames. The horizontal constraint frame includes a horizontal stop member and a constraint-frame coupling member. The constraint-frame coupling member includes upper interference parts to buckle the lower interference parts so as to connect the horizontal constraint frame to the inter-frame connector.

A cabinet assembly including a first frame having a first open channel, a second frame spaced from the first frame with the second frame having a second open channel, and a plurality of beams extending between the first and second frames and interlocking to each of the first and second frames. Each of the beams include a bottom side, a top side opposite the bottom side, and a pair of opposing recessed portions extending from the top and bottom sides. Each of the recessed portions has an upper surface and a lower surface with the upper surface being disposed below the top side. A portion of the bottom side and the entire recessed portion is disposed within the first open channel. The top side is disposed outside the first open channel to interlock the beam to the first and second frames.

A shelf support beam (130) for use in a shelving unit (10) to support a shelf (22). A structural member (132) has a C-shaped cross-section. A web (144) separates a top flange (146) from a bottom flange (162). The top flange (146) is configured to support the shelf (22). The web (144), the top flange (146), and the bottom flange (162) define a channel (142). The channel (142) defines a cavity height (D1). The top flange (146) and the bottom flange (162) define a top flange width (D2) and a bottom flange width (D3), respectively. A ratio of the cavity height (D1) to a sum of the top flange width (D2) and the bottom flange width (D3) is greater than 1.707 or greater than 1.8. The cross-section has a moment of inertia of greater than 0.0613 or at least 0.0617. The web (144) includes a recessed region (164) in which the structural member (132) is offset in a direction into the channel (142). A centroid (148) of the cross-section is within 0.125 inch of the recessed region (164).

A shelving system comprises four corner columns, a plurality of substantially horizontal support beams, and a plurality of beam braces. Each of the support beams extends between two of the four corner columns, and each support beam is paired with a corresponding second support beam to form pairs of support beams. Each of the beam braces extends between the support beams of one of the pairs of support beams and comprises a first end portion, a second end portion, and a middle portion. The first and second end portions comprise substantially planar faces. The middle portion is between the first end portion and the second end portion and comprises first and second edges, wherein the first end portion and the second end portion extend away from the first and second edges, respectively, in opposite directions.

A cabinet includes four upright members having a triangular section and including two outer boards, an inner board, and two longitudinal groove formed at a joining portion of a first end of the inner board and an end of one outer board and at a joining portion of a second end of the inner board and an end of the other outer board respectively, the inner board including an upper first through hole and a lower second through hole; a plurality of board members each including four through holes at four corners respectively; a plurality of fastening devices at the through holes of the board members respectively, each fastening device including a hook assembly and a bolt and nut combination for securing the hook assembly, the upright member, and the board member together; and three board elements each disposed between the grooves of two adjacent upright members.

An example curtain system can include: a curtain forming a flexible body with an opening at each corner of the body; a tensioning device at each corner of the body of the curtain to couple the curtain to a backside of a rack, wherein each tensioning device includes a hook member with a first end sized to engage an opening in the rack and a threaded second end; and a nut configured to be threaded onto the threaded second end of the hook member to tension the curtain relative to the rack.
