A collapsible tow bar assembly adapted to extend between a towing vehicle and a towed vehicle. A frame is provided which includes a bearing element secured to the front end of the frame and a mounting element secured to the rear end of the frame. The mounting element is adapted to be selectively connected to the receiver hitch of a towing vehicle, while the bearing element extends rearward toward the towed vehicle. A pair of elongated, telescopic swing arms are pivotally secured to the bearing element and extend to the towed vehicle for attachment thereto. The bearing element further includes a yoke rotatable about a ball joint having at least two degrees of freedom which allows for movement of the swing arms in both vertical and horizontal planes. The swing arms further include pivot flanges that are pivotally secured to the swing arms at an end nearest the towed vehicle. A pair of tow vehicle mounting brackets extend from the frame of the towed vehicle vertically upward, such that when not in use, the tow bar assembly may be collapsed and securely stored adjacent the rear bumper of the towing vehicle. |
