US Patent 8162576 Cargo bar with quick release

The cargo bar includes a toothed rod and a ratchet actuator. The ratchet actuator is composed of a carriage, a wrench bar with a handle, a main pawl, an auxiliary pawl and an elastic member. When the handle is reciprocated, the wrench bar drives the pawls to push teeth on the toothed rod, and then the toothed rod is elongated outwards. The carriage is disposed with a rotatable release key. When the release key is rotated in a specific direction, the auxiliary pawl and the main pawl will be pushed directly and indirectly by the release key, respectively, and then the two pawls withdraw from the toothed rod to make the toothed rod bidirectionally slidable.
