A door opening system for a merchandise container comprising a plurality of bay doors, the door opening system comprising a wheel in frictional contact with a bay door of the plurality of bay doors; and a motor connected in driving arrangement with the wheel. The motor drives the wheel to rotate and thereby to control a movement of the bay door of the plurality of bay doors between a closed position and an open position.

A locking slider can be used for a door trim, which has a plate and is mounted on a center roller of a sliding door. The locking slider includes two opening/closing members that are positioned on the plate to face each other and fastened or unfastened as multiple protrusions thereof engage or disengage. Two coupling members are formed at both sides of the plate to face each other so as to allow the opening/closing members to be seated on a movement route of the sliding door. The coupling members are configured to apply force to the opening/closing members from outside to inside. A separating member is formed at one side of the plate so as to be positioned between the coupling members. The separating member is configured to apply force to the opening/closing members from inside to outside.

This invention is a retractable cargo wall for flatbed trucks and trailers that lowers into an enclosure that may be rollup canister or tray. Once the cargo walls are lowered, the posts supporting the walls may collapse into the bed, thereby transforming a bed with cargo walls into a flatbed. It is also anticipate that a truck or trailer bed with posts can be transformed into a flatbed truck or trailer.
