Abstract:
1. A retractable cargo carrying device comprising: an openable storage box pivotally attached to a telescoping rail system, said telescoping rail system pivotally attached to at least one base rail for attachment to the top of a trailer such that the telescoping rail system and the storage box pivot simultaneously to always maintain the storage box parallel with the base rail as the telescoping rail system raises at an angle above the base rail and as the telescoping rail system lowers back onto the base rail and as the telescoping rail system extends at an angle to lower the storage box toward the ground and retracts to raise the storage back over the base rail, means for reversibly raising the telescoping rail system at an angle above the base rail, and means for simultaneously maintaining the storage box in a parallel orientation relative to the base rail as the telescoping rail system is reversibly raised at an angle, wherein said means for simultaneously maintaining the storage box in a parallel orientation relative to the base rail as the telescoping rail system is reversibly raised at an angle further comprises: pivotal attachment of one end of the storage box to said telescoping rail system, means for simultaneously reversibly lifting a second opposite end of the storage box attached to said box.
