  • Patent number: 4101126
    Abstract: There is disclosed a game dart having a pivotally moveable point which is coupled to the barrel section of a dart within an aperture located in the barrel section and of a diameter larger than the diameter of the dart point section. The space between the aperture and the dart point section contains an elastomeric material permitting the point to flex or pivot upon striking a metal rib associated with a dartboard. Other embodiments depict a flexible point section which due to its construction, will flex or pivot; while other embodiments depict techniques for coupling the point section to the barrel to allow flexing of the dart point when contacting a metal rib.Another apparatus which circumvents the bounce-off problem depicts a dartboard employing special cross-sectional metal ribs to provide a sliding surface for the dart when the pointed end contacts the rib.
