The rack frame has at least one front rod and at least one rear rod. Each front rod has an extension rod mounted retractably on a top of the front rod and having a front wheel.

A shipping and display container includes a top box installable over a bottom box. The bottom box is configured to receive goods provided in the bottom box in an upright and folded orientation and includes a pair of opposed sidewalls and at least one elongate divider affixed to the bottom box and extending between the opposed sidewalls and configured so as to maintain the goods in the upright and folded orientation. The top box is installable upon the bottom box with the goods received therein in the upright and folded orientation for shipping of the goods and is removable from the bottom box after shipping. The bottom box and the divider cooperate to maintain the goods in the upright and folded orientation for display thereof after removal of the top box.

In some embodiments, various systems, apparatuses and methods are described herein includes back end stocking shelving units that are configured to extend along sides of adjacent shopping aisles in a back-to-back configuration with a secure central aisle running between the shelving units to provide back end stocking access to both shelving units. The secure central aisle can have a restricted access point on one or both ends thereof.

An apparatus includes a shelf having a front edge, a solar cell circuit disposed at the front edge, a display screen, and a controller operatively coupled to the solar cell circuit and the display screen. The controller monitors the period of a waveform of a charging voltage of a storage capacitor of the solar cell circuit, displays an image on the display screen in response to a change in the waveform timing. A system includes a plurality of shelves each having a front edge, a solar cell circuit disposed at the front edge of each of the plurality of shelves, and a controller operatively coupled to the solar cell circuits. The controller monitors the frequency at which a power transfer of each solar cell circuit occurs, and signals a device in response to a change in the frequency at which the power transfer occurs.

A shipping and display container includes a top box installable over a bottom box. The bottom box is configured to receive goods provided in the bottom box in an upright and folded orientation and includes a pair of opposed sidewalls and at least one elongate divider affixed to the bottom box and extending between the opposed sidewalls and configured so as to maintain the goods in the upright and folded orientation. The top box is installable upon the bottom box with the goods received therein in the upright and folded orientation for shipping of the goods and is removable from the bottom box after shipping. The bottom box and the divider cooperate to maintain the goods in the upright and folded orientation for display thereof after removal of the top box.

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.

A display rack comprises shelves and a base. Each shelf comprises a sensor mat comprising a lattice of load sensors. The base is configured for measuring a total weight, which includes weights of any objects positioned on the shelves. The system is configured for determining object addition or removal event data based on in time corresponding changes of: total weight measured at the base; and binary load status of multiple load sensors of a sensor mat of the display rack. A binary load status of a load sensor indicates whether the load sensor at least in part supports an object or not. The event data comprises: an object weight based on said change of total weight measured at the base; and an object support shape and an object location both based on said change of binary load status of multiple load sensors of said sensor mat of the display rack.

A footwear storage and display rack includes a mounting member configured to be mounted to a wall or other generally vertical surface. The mounting member includes an upper portion and a lower portion. A footwear shelf includes a proximal section and a distal section with the proximal section extending from the lower portion of the mounting member so as to be configured at an angle between about 0 degrees and about 90 degrees with respect to the wall or other generally vertical surface when the mounting member is secured to the wall or other generally vertical surface. The distal section extends from the proximal section. An accessory support extends from the upper portion of the mounting member.

A display table for displaying perishable produce items comprises a base; a produce bed on which the perishable produce items are positioned; and an air flow system for providing air circulation and ventilation at the produce bed. The air flow system comprises a plurality of ducts under the produce bed; an air distribution box that evenly distributes the air through the ducts; and a plurality of fans that circulate the air from the ducts under the produce bed to a region above the produce bed. The display table further comprises a control device that controls a flow of the air via the fans to the produce bed according to a state of the perishable produce items on the produce bed; and a self-contained power panel that generates power for the fans, the air distribution box, and the control device, wherein the power panel includes a cell power electrical system.

A shelf system includes: a shelf body with at least one storage space; an item identification pattern on a horizontal edge of the storage space and extending by a preset length along a length direction of the horizontal edge; an image capture unit configured to obtain image information of the storage space, the image information including the item identification pattern; and a processor configured to, based on the image information, determine storage situation of a matching item that matches the item identification pattern and is stored in a preset placement range in the storage space. The preset placement range is an extension space which is in the storage space and which is defined by a horizontal plane corresponding to an extension range of the item identification pattern by a preset extension length. There is a preset correspondence relationship between the item identification pattern and the matching item.
