Abstract
A toy vehicle is supported on one end by at least one wheel and on the other end by a fly wheel which is capable of being energized by pulling a gear rack across a pinion which is connected to the fly wheel. On one of the side surfaces of the fly wheel, a material is located which, when contacted by a flint, is capable of emitting sparks. A flint holding member is positioned adjacent to the fly wheel with a flint located on the flint holding member so as to contact the material on the side of the fly wheel. In conjunction with rotation of the fly wheel, sparks are emitted from contact of the flint with the material. Thus, as the car is propelled across a support surface by the fly wheel a trail of sparks are given off.
Claims4
A toy vehicle which comprises:
- a chassis having a first end and a second end;
- at least one wheel rotatably mounted proximal to said first end of said chassis for rollably supporting said first end of said chassis;
- a flywheel mounted about a flywheel axle proximal to said second end of said chassis, said flywheel at least partially supporting said second end of said chassis;
- a pinion gear rotatably mounted about said axle and operatively connected to said flywheel such that rotation of said pinion gear rotates said flywheel;
- a guide channel located on said chassis in association with said pinion gear, said guide channel for receiving a gear rack member and locating said gear rack member in mesh with said pinion gear whereby said flywheel can be energized by rotation of said flywheel by said pinion gear by movement of said gear rack within said guide channel to rotate said pinion gear;
- a material located in a pattern around one side of said flywheel, said material capable of interacting with a flint so as to produce sparks;
- a flint holding member axle located on said chassis;
- a flint holding member pivotally mounted to said chassis by said flint holding member axle, the axis of rotation of said flint holding member about said flint holding member axle being orthogonal with respect to the axis of rotation of said flywheel about said flywheel axle;
- a flint positioned on said flint holding member in a location so as to contact said material on said flywheel;
- a biasing means associated with said flint holding member, said biasing means biasing said flint holding member in a direction so as to bias said flint against said material on said flywheel whereby, as said flywheel rotates, said flint is in contact with said flywheel and produces sparks in conjunction with said rotation of said flywheel;
- a sound means located on said chassis in operative association with said pinion, said sound means includes a resonator chamber and a pick up member, said pick up member attaching to said resonator chamber and projecting from said resonator chamber toward said pinion so as to contact said pinion, said pinion vibrating said pick up member in response to rotation of said pinion.
