An electric shelf includes at least one column to be installed on a wall, a slidable component arranged on the column to slide along the column vertically, at least one layer of shelf board component connected to the slidable component to move simultaneously with the slidable component, and a linear driving device connected to the slidable component and the column to actuate the slidable component to move relative to the column. Advantages of the present disclosure compared to prior arts include a simpler structure and less space occupied by the shelf board component.

A cantilever shelving system is disclosed and can include a frame structure, a cantilever shelf support structure, and a plurality of load-bearing shelves that can be supported by the cantilever shelf support structure and the frame structure. The shelves can be positioned laterally adjacent to cantilever support arms of the cantilever shelf support structure, and the shelf support surfaces can be coplanar with upper walls of the cantilever support arms. Ends of laterally adjacent shelves do not overlap with a front side of a vertical support member to which the cantilever support arm is mounted. The cantilever shelving system can accommodate various user requirements and can be operably integrated with standard commercial and/or industrial equipment or machinery.

Provided is a rack easy to assemble and disassemble, comprising a front frame, a rear frame, and a number of shelves arranged between the front frame and the rear frame for placing articles thereon, wherein a number of supporting members for supporting the shelves are symmetrically distributed on the front frame and the rear frame, and the width of the shelves is slightly greater than that of the front frame and the rear frame. Compared with the prior art, the supporting members of the present invention for supporting the shelves are symmetrically distributed on the front frame and the rear frame, such that the shelves are directly placed on the supports on the front frame and the rear frame when in use, and the shelves can be removed from the supporting frames when the rack needs to be stored. The rack has a good bearing capacity, is easy to disassemble, assemble and use, and has a small package size after disassembly and is therefore convenient for storage.

A datacenter rack for vertically stacking a plurality of electronic devices is provided. The rack has a frame assembly having two vertical support components and a plurality of removeable trays configured to be inserted between and supported by the vertical support components. Each tray has a pair of opposing sides extending parallel to a longitudinal axis and each of the pair of opposing sides has a tensioned adjustment mechanism to shorten a length of each side to compress the tray in the longitudinal axis, with the tensioned adjustment mechanisms providing a tensioning force against the compression. Each tray also has a top surface with a movement facilitating arrangement for facilitating movement of an electronic device along the tray in the longitudinal axis.

An adjustable shelving assembly for a refrigerator appliance includes a braking rack fixed on a rear wall of a cabinet and a drive screw extending substantially parallel to the braking rack. A shelf is fixed to a clutch assembly that includes a half nut positioned around the drive screw and a brake pawl positioned adjacent the braking rack. An actuation mechanism is operably coupled to the half nut and the brake pawl for moving the clutch assembly between a first position where the half nut closes to engage the drive screw and the brake pawl is disengaged, and a second position where the half nut is open and the brake pawl engages the braking rack.

The invention provides a unique and multifunctional Bedding Rack design in wood and metal materials for the storage and display of King- and Queen-Size Comforter Sets composed of bedspreads such as quilts, comforters, and duvets and a plurality of pillows and shams, and other bedding and sleep-related items. The Bedding Rack consists of two decorative vertical stanchions with hooks for hanging sleep apparel, one or two top rails for supporting the bedspread, two mid-level shelves composed of rails and cross bars for storing pillows and shams, a preformed lower level shelf for storing slippers and items too small for the mid-level shelves, and extended feet supporting the stanchions to provide stability. The dimensions of the Bedding Rack are such that large-size bedspreads do not touch the floor or droop off the end of the top rails when draped over it. The wood and metal Bedding Racks are manufactured as either fully and permanently assembled embodiments or the racks can be produced and shipped in a compact container for assembly by the seller or buyer where no special tools are required. The wood racks employ numerous types of tight fitted, self-locking carpentry joints to allow for assembly and the metal racks employ COTS fasteners to assemble the apparatus. A plurality of unique methods and means are described here for connecting components together and for setting the lower shelf in place so that it can be removed or set at different heights.
