A structural board comprises a surface board and a bottom board. The bottom board comprises a first supporting surface and a second supporting surface, and the surface board is fixedly connected on the second supporting surface. The bottom board comprises a plurality of protruding cavities spaced apart from one another. Two end surfaces of each of the plurality of protruding cavities along a protruding direction of the plurality of protruding cavities respectively defines the first supporting surface and the second supporting surface. Each of a plurality of straight ribs is defined by two adjacent, spaced apart protruding cavities of the plurality of protruding cavities. Some of the plurality of straight ribs are connected together in an extending direction, and the plurality of straight ribs with different extending directions extend to be cross-connected to one another to form a polygonal mesh structure that defines the first supporting surface.

A furniture unit in the form of a multi-function table having a base, a top surface attached to an upper part of the base, a refrigeration assembly located within the base and defining a refrigerated storage area accessible by a drawer, and a non-refrigerated storage assembly located within the base and accessible by one or more drawers. The top surface may be the uppermost surface of the table and can cover substantially the entire table. The table may include other features including lighting, audio speakers, power outlets, USB ports, and a wireless charging pad. Operation of the refrigeration assembly and various features of the table may be controlled by a control section and programmable controller provided with the table. The controller may communicate wirelessly with a personal electronic device operable to program the controller and control operation of the features of the table.

A workstation includes a work surface disposed in a first horizontal plane and a multi-tiered food preparation receptacle positioned adjacent the work surface. The multi-tiered food preparation receptacle includes a first pair of rails and a second pair of rails. The first pair of rails defines a second horizontal plane and the second pair of rails defines a third horizontal plane. The third horizontal plane is located below the second horizontal plane and the second horizontal plane is located below the first horizontal plane. The first pair of rails and the second pair of rails are configured to receive items of food service equipment and permit the items of food service equipment to translate in the multi-tiered food preparation receptacle relative to one another without interference.

A blow-molded unitary structure includes a panel having upper and lower panel surfaces and a ridge extending downward beyond the lower panel surface. The ridge includes a first side surface, a second side surface, and a lower ridge surface joined with the first side and second side surfaces of the ridge. The ridge further includes a plurality of depressions formed at one or more of the first side surface, second side surface and lower ridge surface. The plurality of depressions enhances the strength of the ridge, and the ridge in turn enhances the strength of the structure.

A blow-molded unitary structure includes a panel having first and second panel walls and a generally hollow interior between the first and second panel walls. The structure also includes a plurality of depressions, or at least one ridge, or both the depressions and ridge to enhance the strength of the structure. The plurality of depressions is monolithically formed with the panel, recessing from the second panel wall toward the first panel wall. A depression has a side wall composed of first and second segments. Cross-sectional-wise, the first and second segments have different widths and thus collectively forms a step between the first and second segments. A ridge is also monolithically formed with the panel and includes a section, at which the width of the ridge varies along the height direction of the ridge.

A desktop lifting platform includes a lifting column, a desktop, a base, a controller, and a manipulator, wherein the base is placed on a work platform like a desk; the lifting column includes a drive motor; the controller includes a main control unit (MCU) and a motor-driving circuit, the output end of the MCU is connected to the motor-driving circuit; the desktop lifting platform includes a sensing unit adaptable for detecting or sensing whether the desktop lifting platform hits an obstacle or tilts, such that when sensing that the desktop lifting platform hits the obstacle or the tilts, the sensing unit emits a signal to the controller for controlling the lifting column to stop lifting.

The systems described in this disclosure can be used with a storage system to provide a platform for items and/or papers such as blueprints. A container includes a top panel that is pivotal relative to the container. The container may include additional panels that are pivotal with respect to the top panel and that rotate away from the top panel to extend the platform provided by the top panel.
