Abstract
A ratcheting tie down apparatus and system. Embodiments include a ratchet assembly affixed to a tie down shaft having a longitudinal axis, the ratchet assembly including a ratchet gear, a ratchet head, a ring pawl between the ratchet gear and the ratchet head, and a compression spring between the ring pawl and the ratchet head. A plurality of ramped protrusions of the ring pawl engage a plurality of ramped indentations in a back surface of the ratchet gear, such that when the ratchet head is rotated in a first direction, the ring pawl engages the ratchet gear so that the ratchet head and ratchet gear rotate as a single unit, and when the ratchet head is rotated in a second direction the ring pawl disengages from the ratchet gear such that the ratchet head and ratchet gear rotate independently.
