Vehicle and cargo ratcheting tie down apparatus and system

摘要

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.

主权项

1. A ratcheting tie down system for a transport trailer, the system comprising:
a ratchet assembly affixed to an end of a tie down shaft having a longitudinal axis, the tie down shaft being affixed to the transport trailer; and a pawl mechanism coupled to the ratchet assembly, wherein the ratchet assembly comprises:
a ratchet gear, the ratchet gear having engagement teeth on an outer circumference of the ratchet gear configured to receive the pawl mechanism and a plurality of ramped indentations formed in a back surface of the ratchet gear,a ratchet head with a front surface positioned in opposition to and in mechanical contact with the back surface of the ratchet gear, the ratchet head have a spline extending from an inner face,a ring pawl disposed between the ratchet gear and the ratchet head, the ring pawl having an inner circumference configured to engage the spline of the ratchet head, the ring pawl further having a plurality of ramped protrusions extending from a front surface of the ring pawl and in contact with the ramped indentations of the ratchet gear, anda compression spring disposed between the ratchet head and the ring pawl, the compression spring configured to cause ramped protrusions of the ring pawl to engage the ramped indentations of the ratchet gear,wherein the ring pawl is configured to engage the ratchet gear when the ratchet head is rotated in a first direction such that the ratchet head and ratchet gear rotate as a single unit, and the ring pawl is configured to disengage from the ratchet gear when the ratchet head is rotated in a second direction such that the ratchet head and ratchet gear rotate independently.
