A novel logistics system is disclosed involving a roll container (100) with a base (110) and two elongated supports (120) that are supported by the base (110). The supports each have a plurality of individual slots (122) provided in a spaced apart configuration along the supports (120) for receiving a tab (133, 134) of a respective plurality of shelves (130) in a spaced apart configuration. The roll container may further include a folding mechanism between the base and the supports for turning the supports between an operational state and a folded state. In the operational state of the roll container the supports extend transversally in respect to the base. In the folded state of the roll container the supports extend parallel to the base.

Foldable storage compartment having front and rear panels that are traversable closer to or further away from each other is disclosed. Left and right side collapsible panels may be attached to the front and rear panels. The shelves of the foldable storage compartment may be interlinked with each other by way of a vertical linkage rod and connected to the front panel with a front panel linkage so that traversal of the front and rear panels closer to or further away from each other will also collapse and erect the shelves simultaneously.

Multi-level delivery systems and various apparatus associated therewith are presented. Multi-level delivery systems include a number of integrated, modular and interchangeable compactible elements that may work either alone or in conjunction with other such elements to allow for the deployment of a delivery system having a smaller overall spatial footprint when compared to comparable conventional delivery systems. Apparatus combining to form a delivery system may include one or more of: a compactible container cart, a compactible cart hauler or trailer and a propulsion means. These elements or apparatus may be deployed in any combination, either together as an integrated system or with compatible conventional apparatus. In combination, delivery systems maximize space efficiency, and allow for adaption to any environment and scale.

A foldable cart comprising an upper frame, a lower frame, and a plurality of legs attached to and supporting the upper frame and the lower frame is disclosed. Each leg is configured to be folded into a folded configuration from an erect configuration. Each leg comprises a lock configured to hold the leg in the erect configuration. The lock comprises a lock bar movable between a locking position and an unlocking position, an internal support brace, wherein the lock bar extends through the internal support brace, and a spring configured to bias the lock bar into the locking position to hold the leg in the erect configuration. The lock bar is spring-loaded against the internal support brace, wherein the entire length of the spring surrounds the lock bar, and wherein the spring is confined entirely within the internal support brace.

The invention relates to a display, a kit, and a method for displaying goods. The display has a compact and one or more built-up configurations. The display has shelves that can be supported by hingedly connected, slideably attached, and telescopic side walls. The kit has a display and an advertisement wall for the display. The method relates to the spacing of two shelves by means of two side walls by exerting a force on one of both shelves and hinging and sliding the side walls to a position in essence perpendicular to both shelves.
