<p>A ball propeller, has a ball chamber (5) into which a ball is accurately and securely positioned beneath a vertical shaft (1) arrangement which when pressed downwards, will eject the ball outwards from the ball chamber. The choice of the user in selecting which of the tactile material are to be placed in contact with the ball (thereby imparting differing amounts of backspin upon the ball), the adjustability of the flap (9) (thereby controlling the balls trajectory) and the downwards force applied by the user upon the vertical shaft determines the exit velocity of the ball from chamber, and therefore the balls distance travelled outwards, giving the user control of the balls direction, distance, height and amount of backspin to be imparted upon the ball. The putting mechanism (11, 14) allows the user to propel balls horizontally with control over both line and distance. The ball propellers principal application would be in a miniature golf game.</p> |
