发明名称 Dart board for blunt headed dart - has flexible target grooves to wedge taper point of dart body
摘要 <p>A target game is similar to a dart board and uses darts (10) whose leading end is rounded off. It also has a decreasing taper towards the front end of the arrow which is equipped with several knurled rings (14). The target board (11) is made from a flexible material. It is provided with concentric channels produced by perpendicular walls (15) that are raised from the target board base. The spacing between the walls is such that the tapered end of the dart (10) will wedge itself inside the channel when it hits the board.</p>
