ABSTRACT:
A piggyback toy car and truck assembly in which all four wheels of the car are driven by a battery-powered motor, the truck being of the flat bed type and motorless. The car is switchable from a neutral mode to operation in either the forward or reverse mode, its front and rear wheel axles each having a drive pinion mounted thereon whose teeth are projected below the chassis. Lying on the flat bed of the truck is a ramp having a pair of tracks for accommodating the car wheels. The ramp is slidable from a retracted horizontal position to an extended horizontal position in which the rear half section of the ramp overhangs the rear of the bed and is pivoted therefrom so that it is then free to swing down to form an inclined ramp. With the ramp so inclined, the car in its forward mode climbs up the ramp until it reaches its front end and causes the inclined ramp to return to its horizontal extended position. At this position, the front pinion on the car meshes with a ramp gear operatively coupled to a ramp pinion that engages a rack running along the bed to cause the ramp to advance to its retracted position. At this position, the rear drive pinion of the car meshes with a bed gear operatively coupled to the rear wheels of the truck whereby the motorized car then acts to drive the motorless truck in the forward direction.
