Abstract
Abstract A launching device for wheeled toy vehicles has a housing with a vehicle support surface located on the housing. An opening is located in the support surface so as to allow one of the wheels of the vehicle to be partially located within the opening. An element in the housing is movable toward and away from the opening and when moved toward the opening with the wheel of the vehicle located in the opening the element contacts the wheel to lift the wheel out of the opening so as to launch the vehicle from the housing. A release lever is connected to the element so as to lift the element toward the opening when it is desirable to release the vehicle from the housing.
