  • Retractable cargo carrying device
    Patent number: 8322580
    Abstract: The present invention is a retractable cargo carrying device that can be mounted on the top of a trailer such as a horse trailer. The device is provided underneath with a telescoping rail system that secures to the top of the trailer and to a storage box of the device. This telescoping rail system allows the storage box to be lowered near to the ground so that items can be easily placed in the storage box from the ground. Once the storage box is loaded, it can then be retracted back onto the top of the trailer for transport. The storage box has a pivoting attachment to the telescoping rail system that maintains the storage box in a level position at all times, even when lowering and retracting the box relative to the trailer.
