Abstract: A dart having a detachable flight assembly, comprises an elongate metal body having a needle extending axially forwards from the body and a spigot extending axially rearwards from the body, and a flight assembly including at least three flight blades arranged around and attached to a stem, the stem terminating in an adaptor made from a thermoplastics material and including a socket which is adapted to be a push fit on to the spigot, so that the flight assembly is held in frictional inter-engagement with the body. The spigot and socket may each include a corresponding taper. The adaption of the flight assembly may be made from a resilient thermoplastics material and in this case, a co-operating locking projection and recess are formed on the surfaces of the spigot and socket, so that when the socket of the flight assembly is pushed on to the spigot on the body, the locking projection snaps into engagement with the corresponding recess to interlock the flight assembly and the body.

Abstract: A dart flight assembly comprises an adaptor one end of which is arranged to be fitted to the body of a dart, at least one thin metal pin which protrudes from the other end of the adaptor, and at least three blades made from folded sheet plastics material spaced around and mounted directly on the at least one metal pin. A dart flight assembly may have a single pin which is threaded between the flight blades at their junction along the axis of the assembly. Alternatively there may be the same number of metal pins as there are flight blades, the pins being arranged substantially parallel to each other and each pin being held in tangential contact with adjacent pins over part of its length, the ends of the pins remote from the adaptor having equiangular spaced flight blades folded from sheet plastics material slid between them so that the blades are prevented from rotating with respect to the pins.
