Abstract: The present invention is for a slide-out cargo container for the baggage compartments of passenger buses. The retractable cargo box would enable luggage to be easily loaded and unloaded, eliminating undue back and shoulder strain from lifting heavy baggage at uncomfortable angles. Made of a strong, lightweight material such as aluminum, the retractable cargo box would be dimensioned to fit inside the existing luggage compartment at the lower side of the bus. Wheels along the lower left and right sides of the box would glide along special guide tracks to allow the container to be easily extended from and retracted into the baggage compartment. Two doors would be located at the front of the cargo box to eliminate the need to lift heavy luggage over the sides of the box. Door stops would ensure proper closure of the doors, and a safety hook would keep the doors from popping open.
