  • Toy vehicle game with launcher and return means
    Patent number: 4605230
    Abstract: A toy car collision set (10) in which children attempt to crash nonsteerable unpowered cars (28, 30) at an intersection (12) when travelling in either the forward or reverse directions. The set includes at least two sets of tracks (14, 16, 22, 24) connected together at the intersection (12). A launcher (18, 20) is connected at one end of each of the tracks, and includes a piston assembly (34, 38) having a 5 to 1 compression ratio to be easily operated by a child hitting or pushing the top of the launcher. At the other end of each of the tracks, an elastic return means (26, 27) returns the launched cars along their respective tracks, if the car has not crashed at the intersection. The return means includes an elastic strip (52) stretched across the track to rebound a car striking the strip back along the direction in which it came to either strike another vehicle, at the intersection, or to be returned to the launcher for another launch.
