发明名称 Reducing velocity of a rolling object
摘要 A device (13) is provided for reducing the velocity of a passing rolling object (5) by absorbing kinetic energy therefrom. The object (5) can be a lawn bowl. The device (13) has co-operating means (18) which engage with the bowl to absorb kinetic energy without substantially altering the trajectory of the bowl. When used with a bowl it can reduce the length of a bowling rink while permitting a bowler to deliver the bowl as if playing on a full length rink. A bowling rink and a game of bowls using such device (13) are also disclosed.
