  • Patent number: 8926456
    Abstract: The invention provides a ball having a resilient higher density plastic outer cover layer over a lower density plastic core and a bat including a handle and a head, the head having a hitting surface and a back surface, the hitting surface having an elongate and substantially planar hitting surface and the back surface being similarly elongate and having a raised spine running along its elongate axis. The invention is characterised in that the bat is formed from plastic or composite material and has a central cavity, and a target article (set of stumps) includes a weighted base and a panel, the panel being formed from a flexible resilient material and the base including a slot into which the panel may be inserted and thereby retained in an upright position. The panel and slot are adapted such that when struck by an object the panel is free to vibrate.
