Definitions

  • This invention relates to darts.
  • darts comprise a metal point fixed permanently to a barrel, a shaft connected to the barrel at its end remote from the point, and a flight.
  • electronic dartboards which comprise a multiplicity of individual apertures each capable of receiving a plastics pointed dart and each connected electronically to activate one of a plurality of electronic circuits to record, for example, the score achieved by a dart entering that aperture and the total score of the player making that throw.
  • the present invention sets out to provide a dart or set of darts capable of being used either with a conventional dartboard or an electronic board. In another aspect, the present invention sets out to provide a dart or set of darts whose point, weight and/or length can selectively be changed.
  • a dart which includes a barrel which carries or is adapted to carry at one end a shaft capable of receiving a flight and is formed at its other end with means by which a point-carrying extension piece can selectively be connected to or disconnected from the barrel, the said other barrel end being formed with an internally threaded bore for receiving a threaded member protruding from one end of each of at least two individual point-carrying extension pieces, one such extension piece carrying a metallic point and an other extension piece carrying a non-metallic point.
  • the non-metallic point is preferably a plastics (e.g. a nylon) material.
  • the metallic point carrying extension piece may be formed with a through aperture capable of receiving a lever to assist turning and tightening of the extension piece with respect to the barrel.
  • the lever may comprise the point of another dart.
  • the barrel is preferably a "soft-tip" barrel and is preferably constructed from a nickel/tungsten, nickel/silver alloy or from brass.
  • the metallic point is preferably manufactured from steel.
  • the several point-­carrying pieces are of different weights and/or lengths to one another.
  • the points carried by the extention pieces may all be of the same material or of different materials.
  • a dart comprising a barrel formed at one end with a threaded bore capable of receiving selectively one of several point-carrying extension pieces, each extension piece being formed with a threaded member protruding from its end remote from the point carried thereby.
  • the several point carrying extension pieces may each be of different weight and/or length to the other such extension pieces.
  • the invention provides a barrel for a dart which includes at one end means capable of removably attaching to the barrel a point-carrying extension piece.
  • the barrel may include at its other end means capable of removably attaching a flight-carrying shaft.
  • a dart in accordance with the invention comprises an elongate soft-tipped barrel 1, a shaft 2 and a flight 3.
  • the barrel 1 is formed at its end adjacent the shaft 2 with a threaded bore 4 and at its end remote from the shaft with a threaded bore 5.
  • the shaft 2 includes at one end a threaded shank 6 which screws into the threaded bore 4 of the barrel and is formed at its other end with slots to receive the flight 3.
  • the threaded bore 4 of the barrel 1 complements a threaded shank 7 of a steel point-carrying extension piece 8 and a threaded shank 9 of a plastics point-carrying extension piece 10.
  • the plastics point may be produced from any suitable material, including nylon.
  • the dart is capable of being used selectively either with a conventional dartboard, (in which case the extension piece 8 would be used) or an electronic board (in which case the extension piece 10 would be used).
  • the barrel 1 is capable of receiving selectively extension pieces having different weights and/or lengths to suit the preference of the user.
  • the weight and/or length of the extension pieces may be varied to suit any particular player.
  • the weight of the extension piece 8 may be 5 grammes, 6 grammes, 7 grammes, 8 grammes, 9 grammes or 10 grammes, the respective lengths of the extension pieces being 16mm, 18mm, 20mm, 22mm, 24mm or 26mm.
  • the extension piece 8 is constructed of a nickel/tungsten 80/20 alloy.
  • the extension piece 8 may be produced from a nickel/silver alloy or of brass.
  • the extension piece 8 includes a through-aperture 11 to enable a lever to be inserted therethrough to ensure that the extension piece is firmly screwed onto the front end of the barrel 1 of the dart.
  • the lever in practise, may simply be the point of another dart.
  • the dart illustrated in Figure 2 is similar to that illustrated in Figure 1 excepting that the shape of the barrel extension piece 8 is different.
  • the weight of the extension piece may be 8 grammes, 10 grammes, 12 grammes, 14 grammes, 16 grammes or 18 grammes and the respective lengths maybe 14mm, 15.5mm, 17mm, 18.5mm, 20mm or 21.5mm.
  • the diameter of each extension piece is approximatly 8mm.
