Abstract
The universal joint () is provided at the free end () of the arm assembly () in a wheel chock handling unit () for securing a wheel chock (). The joint () includes a main plate (), a first pivot coupling () defining a yaw axis (), and an elongated link () attached to the first pivot coupling () and being pivotable about the yaw axis (). The joint () also includes means for limiting axial pivot movements of the link () within a range of angular positions having a first angular end position and a second angular end position. The joint () can be configured and arranged so that the wheel chock () can self-align using only its own weight, thus the force of gravity, along the entire range of positions along a base plate (), or a portion thereof.
