<p>A cricket ball throwing device 1 comprises a shaft 2, a handle means 3, a gripping means 4 adapted to receive, grip and release a cricket ball and including a channel to accommodate the seam of the cricket ball. The shaft may be curved and flexible. The gripping means may take the form of a cup defining a partial sphere and an opening 5, and having internal dimensions similar to the external dimensions of a cricket ball. The cup may comprise four leaves (8a,b,9a,b; fig.6). The angle between the cup and the shaft may be selected such that, in use, a cricket ball is thrown with a suitable trajectory to bounce at a required length from the thrower.</p> |
