Abstract
Abstract A RACE TRACK TOY IN WHICH ONE OR MORE RACING CARS ARE DRIVEN AROUND A TRACK IN THE NATURE OF A FLAT BOARD HAVING CONTINUOUS GROOVES THEREIN. THE CARS ARE SHIFTED FROM GROOVE TO GROOVE AT INTERSECTIONS IN THE GROOVLES BY REASON OF A SWITCHING WHEEL CARRIED AT THE FRONT OF EACH CAR. THE SWITCHING WHEEL IS ASYMMETRIC AND WILL DIRECT THE CAR INTO WHICHEVER GROOVE HAPPENS TO COINCIDE WITH THE DISPOSITION OF THE WHEEL AS IT ENTERS THE INTERSECTION. THE OPERATOR THEREFORE HAS NO CONTROL OVER THE CARS IN THEIR TRAVEL OVER THE BOARD.
