ABSTRACT:
A manual release apparatus for disengaging a king pin on a truck trailer from a fifth wheel of a truck cab, including an elongated lever arm, a first end of which is pivotally attached to a side of the fifth wheel at a location spaced from the opening through which the release rod extends, a second end of which is spaced away from the fifth wheel extending horizontally from the first end, whereby the lever arm is attached to the release rod, such that a manual movement of the second end of the lever arm will cause the lever arm to be pivoted horizontally about the first end, thereby causing the release rod to be pulled outwardly to disengage the king pin from the fifth wheel. The elongated lever arm is provided with an adjustable extension arm so that the length of the lever arm can be adjusted to an extent desired to best facilitate manipulation thereof.
