DESCRIPTION:
BRIEF SUMMARY
This invention relates to a playing dart in particular, one that has, relative to the dart body or barrel, a biased retractable and freely rotatable point.
BACKGROUND TO THE INVENTION
The skill game of darts is played throughout the world and is competitive when not played as a leisure sport or game. The darts are propelled by the hand toward a disc-like target having a centre bull's eye and circumferential rings, some of which are subdivided into pie-shaped regions, others are chordal. Each of these regions has its own denomination for scoring and each boundary between each region is separated, normally by a shaped round wire, which is organized as a frame work or lattice that overlays the boundaries between each different denominated region to partition the target into physical areas that have unique denominated values. If a dart is thrown toward the boundary of two different denominated regions and it hits the wire which is laid over and runs along the boundary. In many instances the dart bounces off the boundary wire and onto the floor since the point hits the wire head-on. In some instances, where the momentum of the dart is such, or the point strikes the wire other than "head-on" thus near its edge, the point is deflected into the adjacent region, with the point penetrating the region and the dart sticking so as to be awarded points according to the denomination of the region penetrated.
According to the prior art, there is disclosed by one REID in U.S. Pat. No. 5,009,433 issued 22 Apr., 1991 for a "DART FOR AIMING AT A GAMEBOARD". A dart which has a movable point movable along a line with a horizontal longitudinal axis of the body portion of the dart and co-incident with the line with the vertical axis of the dart so that the point can stick to the board and avoid obstructions on the board. Such dart has, within a cylindrical bore of the body portion, either a circumferential clasping means which urges against the outside diameter of the dart point, along the margin of the dart point downstream from an approximate furrel end of the dart or alternatively, a plurality or collection of metal balls or shot which move, after impact of the dart point, into a bore downstream absorbing the impact of the dart point within the body. This particular dart has the disadvantage in that the dart point is not automatically re-set to its most outwardly extending position after the dart is retrieved and pulled out of the dart board, because there is no biasing means to urge the dart point to its outward extent.
THE INVENTION
It is an object of the invention to provide the dart with such momentum, that if the point hits the wire head-on, the point will telescope into the barrel of the dart allowing the body of the dart to carry forward by its momentum. The point thus being relieved slightly of its initial impact pressure on the wire but the point tends to glide around the wire and to penetrate into an adjacent scoring region because of the sustained pressure of the dart barrel moving toward the target and holding the point against the wire while biasing the spring inside the barrel. This action encourages the dart point to slide off the wire and to penetrate a target region adjacent thereto rather than for the dart to bounce off the wire onto the floor without penetrating the target.
It is also an object of the invention to provide a rotatable point relative to the body or barrel of the dart so that when that dart penetratingly rests in its dart target, and an oncoming dart strikes the flight of the dart that is penetrated, the body, barrel and flight of the penetrated dart is free to rotate relative to the point so as to move out of the path of the oncoming dart resulting in a better success rate for the oncoming dart in penetrating a target.
It is an additional object of the invention to provide a sub-assembly and a two-tiered collar that allows the barrel to freely rotate around its extending point such that any subsequent dart that makes contact with the dart already in the board, the rotating motion of that
