  • Patent number: 4155194
    Abstract: A toy launcher is provided for launching airplanes, missiles or the like, the launcher being provided with a base having a drum member pivotally mounted within the base, the periphery of the drum having a bearing for receiving the axis of a joy stick handle which is pivotally mounted with respect to the drum member. A gimbal mechanism within the drum is operatively connected to the handle and to a launch arm extending out from the drum, the launch arm containing a launch mechanism for releasably receiving airplanes or the like for launching the same in response to actuation of a trigger mechanism in the handle. Manipulation of the joy stick angularly displaces the surface of the launch arm to permit pre-positioning of the intended flight path and bank angle of the projectiles to a given attitude prior to launching.
