A storage apparatus attachable to a surface includes a polygonal support frame having first, second, third, and fourth support beams, a plurality of cross beams, and a plurality of suspension legs. In one embodiment, the storage apparatus further includes racks supported on at least a portion of the support beams and defining a first series of racks aligned transverse to a longitudinal axis and a second series of racks aligned along the longitudinal axis with the first series of racks being removable during adjustment of the first and second support beams and the second series of racks being removable during adjustment of the third and fourth support beams.

A storage system has retractable cells used for with storing and transporting articles in totes. A plurality of spaced apart shelves extends transversely between left and right flexible vertical panels. Left and right hangers extend upward from a distal end attached to a shelf to a proximal end at a structural support. A plurality of guide members are attached to the vertical panels, juxtaposed with the shelves. Each guide member slidingly engages a hanger. Means is provided for pulling the left and right hangers upward to raise the shelves upward. The hangers can be secured either to the support or to a shelf above. The left and right panels will fold inwardly between the shelves. The space beneath the shelves will increase to receive an article larger than a tote.

The present invention relates to a folding table. The folding table includes a first table top and a second table top that can move between a folding position and an unfolding position, as well as a first and second table leg component for supporting the second table top, wherein two sets of mutually hinged four-link mechanisms are formed by the first and second table leg component in virtue of table beams, table legs and inclined rods. The two sets of four-link mechanisms realize interference self-locking in the unfolding process. Two triangles are formed for supporting a table top stably, and the stress is uniform. The table top can be folded face to face in two parts, so that the table top after being folded is effectively protected, and scratches on the table top during the production, transportation and using processes are reduced.

A transportation rack includes a frame having a base configured for resting on a surface and first and second track members and positioned parallel to each other and extending upwardly away from the base between respective lower ends and upper ends, a first support member extending between the track members and respectively slidably connected with each of the first and second track members at opposite lateral ends of the first support member, and a second support member extending between the first and second track members and respectively slidably connected with each of the first and second track members at opposite lateral ends of the second support member, the second support member being coupled with the first support member by a flexible connection.
