  • Patent number: 9302193
    Abstract: A corner booster for accelerating toy vehicles includes an entrance to which a toy vehicle enters the booster, and an exit from which the toy vehicle exits the booster. The entrance and exit are orientated so that the toy vehicle turns when traveling from the entrance to the exit. The corner booster further includes a booster member for applying a force to the toy vehicle. The force applied by the booster member increases the speed of the toy vehicle as the toy vehicle travels from the entrance to the exit. The corner booster includes a cocking mechanism that cocks the booster member with preloaded mechanical energy. The preloaded mechanical energy is used to move the booster member to apply the boosting force to the toy vehicle.
