10/982214
Inventors:
William E. Hollis - Pittsburgh PA, US
Edward J. Boyd - Saxonburg PA, US
Edward J. Boyd - Saxonburg PA, US
International Classification:
B62D 53/06
US Classification:
280434
Abstract:
A manual release mechanism for disengaging a king pin on a truck trailer from a fifth wheel of a truck cab includes a substantially straight lever arm with a first end being pivotally attached to the fifth wheel and a second end being spaced away from the fifth wheel extending horizontally from the first end. A pair of flat disks and a pair of slide bars are provided for slideably coupling to a release rod of the fifth wheel, such that a manual movement of the second end of the lever arm will cause pivoting thereof horizontally about the first end, thereby causing the release rod to be pulled outwardly to disengage the king pin from the fifth wheel. The 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. A lock pin is provided for securing the extension arm to the lever arm. A flexible cable secures the extension arm to the frame of the truck cab.
