Abstract
Abstract A toy hovercraft apparatus and which includes a toy hovercraft and a launcher therefor. The hovercraft comprises a frame having an outwardly flaring skirt with a downwardly projecting peripheral lip to form an air chamber therebeneath. A motor, e.g., an electric motor, supported centrally of the skirt, rotates a fan located in an upper portion of the chamber to draw in air through inlets and create a pressurized air cushion in the chamber, which, in turn, causes the hovercraft to float or hover over a floor, or other surface. One or more relatively small rechargeable batteries are also carried on the frame and connected to the electric motor for powering the motor and the batteries may be periodically recharged. The hovercraft is preferably round and is constructed so that the weight is symetrically distributed which permits the torque created by the fan to cause rapid rotation of the hovercraft in a level horizontal plane without imparting horizontal motion to the hovercraft. The launcher includes a base for receiving the hovercraft and a manually actuable ejector mechanism for imparting horizontal thrust to the hovercraft to cause it to travel in a generally horizontal path. The hovercraft has no means for imparting motion to itself or changing the direction of motion, but will travel in a generally horizontal path or change direction in response to forces external to the hovercraft which are imparted to the hovercraft. The launcher also includes a source of electrical power and a recharging mechanism which can be coupled to the hovercraft for recharging the batteries in the hovercraft.
