ABSTRACT:
The apparatus provides for the automatic uncoupling of a toy semitrailer from a toy tractor truck and provides also for automatic coupling of a toy semitrailer to a toy tractor truck. The uncoupling utilizes a ramp in a roadway which is inboard of the tractor truck wheels, and this ramp is engaged by the forward dolly wheels on the semitrailer, which dolly wheels are also inboard of the truck tractor wheels. The coupling of the toy semitrailer to the toy tractor is achieved by a simple beveled end on the rear of the toy tractor, which backs up to the semitrailer, and the king pin of the semitractor rides up this bevel to the pivot flat area of the tractor to drop into the pivot hole. Both operations are carried out in the same locality by a reciprocating dock which is contacted by the semitrailer during its backing up at the time its dolly wheels ride up the ramp to release the tractor. After the tractor vehicle departs, a delayed spring action moves the dock forwardly to move the semitrailer forwardly off the ramp so that the semitrailer may then be contacted by the tractor backing up to it to connect the two vehicles.
