ABSTRACT:
In a trailer hitch connecting a towing vehicle and an trailing vehicle, each "coupling" member of each vehicle has a support component and an attachment component. An adapter is interposed between and attached to the support component and the attachment component of one member. The adapter has a guide plug telescoped with the support component and an adjustment portion coupled to the attachment component and hinged to the guide plug for lateral movement. A pair of angled faces on the adapter serve to cam the components into axial alignment as the towing vehicle and the trailing vehicle are brought closer together. The adapter is capable of both axial and lateral, swinging movement for easy vehicle attachment.
