Abstract

A dart flight has three vanes. The vanes may be 120 degrees apart and fit in a Y shaped slot in dart stem.

Description

TRI-FLIGHTS AND STEMS
Description
This invention relates to the flights and stems used in the game of darts.
The Tn-Flight uses a three vane flight instead of the normal four vane. The flights locate into a Y-shaped slot cut in the top of each stem.
Testing has shown that using three vanes increases the in-flight speed and stability of the dart which potentially improves its accuracy. Once stuck in the dartboard, the three vanes also offer a reduced target area compared with a four vane flight which reduces the chances of subsequent darts striking them and being deflected.
Additional advantages of this design are: 1) The Y-shaped slot of the stem is less easily damaged (for example when struck by another dart) than its cross-shaped counterpart.
2) Less material is used in the production of the flights reducing the manufacturing costs.
The flights can be either moulded as a single piece or constructed from sheet material (paper, plastic or card). The sheet material can either be cut into a single piece which is then folded to form the flight or cut into 2 or 3 pieces which are bonded together.
Flights can be created in various different shapes using these methods.
The stem can be made from any material that can provide sufficient stiffness whilst remaining light enough so as not to unbalance the dart. Suitable materials are plastic, composite, metal or wood. The bottom of the stem has a male 2 BA thread to allow it to be screwed into standard barrel. The thickness of the stem could be tapered down towards the flight to reduce weight. The stem would be made available in a number of different lengths to allow the flight characteristics of the dart to be tailored to the preferences of the thrower.
Figure 1 shows the 3D view of the fully assembled Tn-Flight. Figure 2 shows the end on view of the flight with the three vanes equally spaced at 120 degrees.
Figure 3 shows the stem with its Y slot cut to match the Tn-Flight with the segments equally spaced at 120 degrees.
Figures 4 to 6 show the templates for creating three of the popular flight shapes (standard, pear and kite) from a single piece of sheet material. The fold lines are shown (solid lines fold in and dashed lines fold out)
