A luggage item, a luggage item system and a luggage item adaptor are provided. The luggage item is for use in luggage system comprising a luggage trolley and another luggage item. The luggage item comprises a first side, a second side, a first coupling element and a second coupling element. The second side is opposite the first side and is separated by flanks from the first side. The first side and the second side have an area larger than the areas of the flanks. The first coupling element is arranged at the first side. The second coupling element is arranged at the second side for engaging with a first coupling element of the other luggage item to releasably attach the other luggage item to the luggage item and for engaging with a trolley coupling element of the luggage trolley to releasably attach the luggage item to the luggage trolley.

A wheeled storage box and storage container interlock system includes a hard lid for the storage box and a hard base of the storage container that can be mated and locked together. The lid includes sliding tracks, receiving ports, and a retractable locking component including a buckle to receive and lock to the base when the storage container is stacked onto the storage box. The backside of the base includes tabs and receiving ports. When the base is being stacked on the lid, the tabs on the backside of base can be aligned with receiving ports of the lid and the retractable locking buckle can slide into the receiving ports of the hard bottom. The buckle of the locking component can be used to lock and unlock the lid and the base.

Collapsible carts are disclosed. The collapsible carts include a frame, a load bearing member and a wheel assembly. The wheel assembly includes a housing with a horizontal pin channel and an elongated diagonal channel. The horizontal pin channel may be adapted to guide a pin to transpose horizontally along the horizontal pin channel while rotatably coupling a leg member of the frame to a horizontal section of the load bearing member. The elongated diagonal channel may be adapted to guide the horizontal section of the load bearing member to pivot around a pin axis and move from a horizontal plane in the open condition to a generally vertical plane in the closed condition. The movement of the horizontal section along the elongated diagonal channel actuates the housing to rotate around the generally vertical axis.

Luggage that may be mechanically integrated with a platform, including a piece of luggage including a slit through which the piece of luggage is integrated with a platform for the piece of luggage, a handle fastened to the piece of luggage, for pushing or pulling the piece of luggage, luggage wheels fastened to a first outer surface of the piece of luggage, for rolling the piece of luggage, and a release mechanism extending from the luggage unit to the platform, through the slit, for unlocking the platform, wherein the platform locks and unlocks such that the platform is free to be raised and lowered when it is unlocked, and is not free to be raised and lowered when it is locked.

Disclosed is a device for turning rotatable rods for folding or unfolding wheels of a carrier, the device comprising: a pair of rotatable rods, each of which comprises one or more helical lines; a cross bar comprising helical line coupling portions coupled to one or more helical lines, and one or more elastic members, which provide restoring forces to the cross bar.

A system and method for storing and sequencing a plurality of luggage items. The method includes receiving at least one of the luggage items into a loading area from an entrance conveyor disposed in the loading area. Once received, the luggage items are moved from the entrance conveyor onto a shelf of a container with a loading assembly. The method continues with transporting the container from the loading area to the storage area with an automatic guided vehicle with the luggage item disposed on the shelf of the container. When the luggage items are ready to be processed, the method continues with transporting the first container from the storage area to the unloading area with the automatic guided vehicle with the received luggage item disposed on the shelf of the container. Different embodiments of the loading and unloading assemblies are provided.

A wheeling frame for a suitcase which has its own rolling wheels includes a frame supporting a pair of leaning wheels arranged at ends of a pair of pivotable legs, with a first wheel arranged at the end of a first leg and a second wheel arranged at the end of a second leg. The leg positions are adjustable between a stowed position and a deployed, adjustable position extending at an angle to the frame. The legs have a movable pivoting axis and adjustable lengths. A handle system at a proximal end of the frame is adjustable in length and angle, and is operable in conjunction with the leaning wheels to roll the suitcase in a stable leaning position, to allow walking the suitcase on steps of a staircase, and to be converted into a suitcase table, to ease packing and unpacking.
