  • Patent number: 4577899
    Abstract: A liner cup 2 can be removed from a golf hole 1 by a tool with a shaft 6 and wedge-shaped member 9 pivoted on arms 8 extending from the shaft so that they fold inwards as the shaft is positioned in the cup (by placing nose 6d into the conventional bottom recess) and fold outwards to grip by their curved outer edges 9a at the inner liner cup surface as the shaft is pulled up, thereby removing the cup 2 from the ground by frictional engagement of the edges 9a. In case simple frictional engagement is inadequate, e.g. in wet weather, a sleeve 12 is mounted to be slid upwards by arm 13 when second handle 14, pivoted at 15 to the shaft is manipulated so that limb 14a lies nearest handle 7, or conversely downwards when 14 is oppositely pivoted.
