摘要： A starting system having a delayed starting indicator apparatus comprised of a housing, a movable indicating element, a resetting element and a premature start indicator mechanism. The indicator apparatus simulates a ''''Christmas Tree'''' starting device commonly used for drag races. As the movable indicating element drops within the housing in a retarded fashion, spaced, paired openings in the housing make visible a sequential showing of color including a different color to indicate the beginning of the race. The premature start indicator mechanism causes a still different color to appear by offsetting the indicating element. The apparatus is easy to manipulate, simply constructed, rugged, inexpensive to manufacture and exciting to use.

摘要： A toy vehicle with a large knob at the rear and a rubber band motor that is wound by rolling the knob back and forth on the ground. The vehicle may then be released and run under the influence of the rubber band. Alternatively, the knob may be pulled back to prevent immediate unwinding of the motor. The vehicle may then be started by tipping it back to a ''''wheelie'''' position so that a release member behind the rear wheels is pressed up to release the rubber band motor or the vehicle may be pushed by hand or otherwise propelled until it is desired to press the release member and release the rubber band motor.

摘要： A toy hill-climbing system is disclosed including a simulated motorcycle, a motorcycle launcher, a roadway simulating rough terrain and parallel tracks connecting the roadway and the launcher. The roadway is placed at a greater vertical height than the launcher so that the tracks are upwardly sloped to simulate an actual motorcycle hill climb competition.
