ABSTRACT:
A ratchet tie down structure is shown that is designed to hold heavy objects in place on a transport vehicle such as a flat bed trailer, a car carrier, a railroad car and the like. The mechanism includes a base element attached to the transport vehicle that has pair of cooperating elements having interfitting ratchet teeth and a latch that permit a shaft to be turned in one direction to tighten a flexible holding element attached to the object with the latch holding the tension therein until the ratchet teeth on the two elements are disengaged. The structure includes a driving connection by which the shaft may be rotated in one direction to wind a tension in the flexible holding element and the latch being selectively operative to disengage one of the elements with the ratchet teeth from the other in order to release the tension in the flexible holding means when the heavy object is to be unloaded.
