The present invention relates to a novel trolley coupling structure that allows coupling of base parts of trolleys aligned in the vertical or horizontal direction. The present invention provides a trolley coupling structure in which a first receiving recess part is provided in a base part of one trolley, a second receiving recess part is provided in a base part of another trolley, a locking member is pivotally attached to the first receiving recess part, a recess part body and a bent section are formed in the respective first and second receiving recess parts, and retaining of the locking member is achieved by constraining and locking a constraining piece part of the locking member at the bent section.

Collapsible reusable watertight carrying cases are provided in sizes varying from small containers without wheels to large sealable container bins on wheels, to provide large quantities of water or other supplies and cargo. The cases are assembled or disassembled from a joined flat space-saving configuration to a functioning case and vice-versa. The sides of the cases are erected progressively by hand by interlocking self sealing reciprocating channel and channel engaging members elements at the corners. The panels also disassemble progressively by being manually pulled apart. Optional foldable locking latches provide stability and aesthetics to the carrying case. When folded into a flat storage or shipping configuration, the panels stay together, resisting unfolding by virtue of snaps which are either molded into the panels or bonded to them. The carrying cases are resistant to water, dirt, bacteria, molds, allergens, and inclement weather.

A portable advertising platform system for store front, street side and indoor promotions. The platform can elevate signs and products above obstacles. Items are fastened at their tops only allowing them to freely swing; wind resistant. This rugged, lightweight platform is made from plastic or aluminum and consists of several joints interconnected by square shaped insert tubes; thumb screw fastening. Tubes can couple together to form longer members. Joints can rotate 90 degrees to create perpendicular branches. The platform consists of a lower cart with several vertical mounts, supporting an upper web with multiple tiers and overhanging arms. The platform can substantially stretch horizontally, vertically and in width providing numerous configurations. The 4 leg levelers telescope multiple feet both horizontally and vertically to level the cart on rough uneven terrain. Leg levelers also act as durable brakes; friction with ground. Detachable large 8 inch wheels swivel for easy maneuvering.

A cart, such as a kitchen cart, has a bottom shelf supported by leg members. The leg members further support a central shelf or basket at a user-desired position along the legs, and a top support. The top support can retain a top work surface thereto. On at least one side of the cart, arms can pivot outward, adjacent the top work surface, to support one or more work surface extension members. Typically, there may be one work surface extension member on each side of the cart, providing the user with additional workspace and providing the option of removal without interfering with the functionality of the cart.

A cart for medical equipment includes a base having one or more wheels, a column supported by the base, and a platform supported on the column and opposite the base. The platform is configured to mount a piece of medical equipment to the cart. The cart also includes an adapter plate securable to the piece of medical equipment and configured to releasably couple to the platform. The adapter plate includes a locking assembly having one or more handles that upon actuation releases the adapter plate from the platform.
