Abstract
A self-righting flywheel motor operated toy vehicle includes attitude restoration components at the rear thereof, the vehicle having the center of gravity thereof along the longitudinal centerline thereof. A first component includes an attitude restoration plate configured in the form of a spoiler member attached at the rear of the vehicle above the rear wheels and having a width greater than the distance between the outer sides of the wheels for enabling the maintaining of a slight elevational angle of the vehicle when on either side, with a corner of the driving wheel on that side in contact with the surface. The force of the driving wheel tends to self-right the vehicle. The second component includes an elongate somewhat rigid, yet flexible wire member configured to simulate a whip antenna, which is connected to the chassis at a corner thereof at about the rear surface of the rear wheels, and positioned for coaction of an intermediate portion thereof with the spoiler member as the vehicle attempts to scale a generally vertical surface. The resilience during partial deformation of the wire member serves to keep the driving wheels in contact with the surface. As the driving continues, the vehicle turns to one side or the other, and by itself, or with the assistance of the first component, self-rights itself.
