Title:
Darts having low rebound frequency
Abstract:
A dart comprising an elongate body portion, a bore extending axially in said body portion, and a tip arranged for axial movement in said bore between first and second limit positions. The tip is encircled by a spring arranged in the elongate body portion. Flights are fitted to the end of the body remote from said tip and means may be provided for ejecting the flights of the dart upon axial movement of the tip to its first limit position. Preferably the tip is able to move radially in the bore between preferred limits. The advantage afforded by such a dart is that the number of rebounds occurring should the dart strike a wire of a dartboard are greatly reduced in comparison with a standard dart.
