Abstract
Abstract A mini-dolly for transporting vehicles comprising an elongate frame, the latter including a pair of opposite wheel-carrying portions longitudinally spaced from one another. The elongate frame includes a pair of cooperating receptacle members connected thereto, the receptacle members having an adjustable configuration relative to one another for cooperatively receiving a vehicular member such as the wheel of a disabled vehicle. The elongate frame is telescopically adjustable for adjusting both the longitudinal extent thereof and the effective vehicular member receiving configuration of the receptacle members relative to one another. The elongate frame includes two mutually interfitting portions one in the other between the wheel-carrying portion thereof for constituting the telescopic arrangement thereof. The receptacle members are pivotally arranged at the opposite wheel-carrying portions of the frame respectively and may be inclined relative to one another pivotally to support the wheel of the disabled vehicle.
