发明名称 Tether tennis game apparatus
摘要 The invention relates to a tether tennis game apparatus which includes a hollow pole that has a helix formation extending externally therefrom along an operative top segment of the pole. The helix formation defines a helical guide path within which a loop formation, that is formed at one end of a flexible line which has a ball connected at its other end and that can be located around the pole, is displaceable. An indicator arrangement including an elongate indicator element, located for axial displacement within the pole, and a trigger arrangement is operable on the pole to indicate a winner of a game played with the apparatus and which occurs when the loop formation, at the end of a flexible line, reaches an end of the helical guide path.
