Variable planform shelving systems include a variable support platform and a support surface assembly that is supported by the variable support platform. The variable support platform includes frames that can be repositioned relative to each other to vary the planform of the variable support platform. The support surface assembly provides a support surface for supported items. The support surface assembly is flexible and/or comprised of a plurality of linked panels so that the support surface provided varies in response to variation in the planform of the variable support platform.

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.

A combined storage shelf is provided, 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 combined type shelf includes column assemblies, first horizontal constraint assemblies, second horizontal constraint assemblies and storage layers. The column assembly includes assembly holes. The first horizontal constraint assembly has a first horizontal-constraint connecting fastener including horizontal-constraint hanging structures and rivets. The horizontal-constraint hanging structure engages the assembly hole to connect the first horizontal constraint assembly to a front or rear side of the column assembly. The second horizontal constraint assembly includes a horizontal-constraint hole to engage the rivet so as to connect the second horizontal constraint assembly to a left-hand or right-hand side of the column assembly. In addition, the storage layers are disposed between these column assemblies.

The application relates to a method of establishing four profiles which when releasably mounted together are forming a cabinet frame. The profiles are having folding areas comprising cutout parts.

A combined storage shelf is provided, including double-bracing side racks, connection and combination fasteners, storage layers, and beam structures. Each of the double-bracing side racks includes a first upright rod, a second upright rod, and horizontal rods. Each of the connection and combination fasteners includes a body portion, two side portions, fitting grooves, and fastening structures. The storage layers are disposed in the beam structures. Each of the beam structures includes a beam member and beam connection and combination fasteners. Each of the beam connection and combination fasteners includes beam fastening structures. Each of the beam fastening structures is snapped into a fastening structure, so that the beam structures are connected to the connection and combination fasteners.

A shelf support beam (80, 130, 200) for use in a shelving unit (10) to support a shelf (22). A structural member (82, 132, 202) has a C-shaped cross-section. A web (94, 144, 216) separates a top flange (96, 146, 220) from a bottom flange (112, 162, 234). The top flange (96, 146, 220) is configured to support the shelf (22). The web (94, 144, 216), the top flange (96, 146, 220), and the bottom flange (112, 162, 234) define a channel (92, 142, 214) of the member (82, 132, 202). The channel (92, 142, 214) defines a cavity height (C1, D1, E1). The top flange (96, 146, 220) and the bottom flange (112, 162, 234) define a top flange width (C2, D2, E2) and a bottom flange width (C3, D3, E3), respectively. A ratio of the cavity height (C1, D1, E1) to a sum of the top flange width (C2, D2, E2) and the bottom flange width (C3, D3, E3) is greater than 1, is at least 1.20, or is about 1.40. The C-shaped cross-section has a moment of inertia (98, 148, 238) of greater than 0.40, greater than 0.45, or at least 0.46. The top flange (96, 146, 220) includes an elevated portion (100, 150, 222) and a lower or shelf support portion (104, 154, 226) separated by a sidewall (106, 156, 230).

A storage device is provided including a support frame having a plurality of elongated support members and a stiffening bracket carried by the support members. An enclosure may be carried by the support frame. The enclosure may be foldable and have a fabric construction and may be detachably attached to the support frame. A plurality of closeable storage compartments may be provided in the enclosure. The storage compartments may contain items such as towels, clothes, shoes, lotion and other items used by a beachgoer or other user, at the beach or other location.

A combined storage shelf is provided, including double-bracing side racks, connection and combination fasteners, storage layers, and beam structures. Each of the double-bracing side racks includes a first upright rod, a second upright rod, and horizontal rods. Each of the connection and combination fasteners includes a body portion, two side portions, fitting grooves, and fastening structures. The storage layers are disposed in the beam structures. Each of the beam structures includes a beam member and beam connection and combination fasteners. Each of the beam connection and combination fasteners includes beam fastening structures. Each of the beam fastening structures is snapped into a fastening structure, so that the beam structures are connected to the connection and combination fasteners.

The present disclosure provides an advantageous pan jig for installing a pan relative to a frame. The disclosed pan jig semi-permanently engages the pan relative to a frame. Specifically, the disclosed apparatus and method of use advantageously facilitates formation and mounting of a drip pan for use with a system that facilitates aeroponic growing. The disclosed aeroponic growing system may include a plurality of drip pans.
