Abstract
A throwing dart includes a flight movably secured about a shaft, and a tip. When the tip contacts the dartboard, the forward momentum of the flight causes the same to move forward in close proximity to the tip. The flight may be repositioned after play by pulling the same towards the end of the shaft opposite the tip. At least one (1) magnetic element is positioned to removably secure the flight in place.
Claims19
A sliding shaft for a playing dart, comprising:
- a shaft having an affixed magnet and located immediately forward of a flight;
- a receiver;
- and, a barrel, said barrel having a knurled exterior to aid in holding a playing dart, said shaft connects said flight to said receiver;
- wherein only upon impact of a tip, said tip being located at a most forward portion of said playing dart and configured to penetrate a playing surface, does said shaft and its affixed magnet begin to move along a travel path and has magnetically engaged a second washer to effectively reduce an overall length of said playing dart removing a portion of said shaft normally visible on an exterior of said playing dart;
- and wherein a momentum force of said shaft including a mass of said affixed magnet, said shaft and fins is adequate to overcome a magnetic force between said affixed magnet and a first washer.
