The modular structure for shelving comprises:—a plurality of vertical uprights comprising at least one pair of first teeth arranged one on top of the other to define a first interlocking plane;—a plurality of first metal sections provided with a cross section, higher than its width, of substantially tubular and parallelepiped shape, and with two ending parts provided with corners and with one pair of first clamping elements, arranged protruding in the proximity of the corners and superimposed on one another; the first clamping elements being spaced apart from one another to be coupled from top to bottom and in block configuration to any pair of the first teeth along the first interlocking plane, each first clamping element comprising a loop defining a passage slot and each of the ending parts of the first metal sections being substantially flat.

The invention relates to a cross brace (4) comprising an elongate bar portion (41) and two clips (42). The bar portion (41) has two substantially opposite longitudinal ends. The two clips (42) are each arranged on one of the two longitudinal ends of the bar portion (41) and are designed to almost fully enclose a bar-shaped element (22, 52). Furthermore, the two clips (42) can each be brought into an opened position, in which the bar-shaped element (22, 52) can be received by the clip (42) and removed from the clip (42), and into a closed position, in which the bar-shaped element (22, 52) can be fully enclosed by the clip (42). The clips (42) have a lock (425) which locks the clip (42) in the closed position.

A storage rack assembly includes a base steel structure which is interchangeably connected to the storage rack above. The base steel structure assembly is compromised of structural material with bolted connections which allow for the replacement or changing of damaged material due to accidental forklift contact all while the above storage system stays in place.

A crossmember (3) comprises an elongate rod portion (31) and two latching claws (32). The rod portion (31) has a central longitudinal axis, a first longitudinal end and a second longitudinal end substantially opposite the first longitudinal end. The first latching claw (32) is arranged at the first longitudinal end of the rod portion (31) and the second latching claw (32) is arranged at the second longitudinal end of the rod portion (31). The first latching claw (32) and the second latching claw (32) each comprise a gripping portion (321) shaped to correspond to a rod-shaped element (22, 31, 52) and are designed to be mounted on the rod-shaped element (22, 31, 52) without tools. The gripping portion (321) of the first latching claw (32) is offset from the gripping portion (321) of the second latching claw (32) with respect to the central longitudinal axis of the rod portion (31).

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).

An integrated coral cultivation system includes a water tank unit having at least one aquaculture tank configured to contain corals, a water supply unit for supplying aquaculture water to the water tank unit, a drain unit for discharging the aquaculture water in the water supply unit and the aquaculture tank to the outside, an air supply unit for supplying air to the water tank unit, a temperature adjustment unit for adjusting the temperature of the aquaculture water in the water tank unit, a light unit for providing lighting to the water tank unit, and a power source unit for supplying power to the water supply unit, the air supply unit, the temperature adjustment unit and the light unit.

A device for moving a product display assembly off of a shelf. The device includes a body portion that is configured to slide between the product display assembly and the shelf. The body portion has a thickness of from about 0.10 inches to about 0.30 inches.

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.

Disclosed is a utility rack system that includes shelves having a first end, a second end, and a pair of end supports. Each of the pair of end supports is configured to support either the first end or the second end of the one or more elongated shelves. Each of the pair of end supports includes a first vertical member and a second vertical member, an upper cross member pivotally coupled at a first end to the first vertical member and pivotally coupled at a second end to the second vertical member, and a lower cross member pivotally coupled at a first end to the first vertical member and pivotally coupled at a second end to the second vertical member. The utility rack system also includes a diagonal support having a sliding lock mechanism coupling a first end of the diagonal support to the first vertical member.
