  • Patent number: 5048845
    Abstract: An entrapment assembly suitable for use as a "hole" in, e.g., a flying disc golf game, is disclosed. The assembly consists of a top portion operatively connected to a nest bottom portion, wherein at least one deflection member is operatively connected to said top portion and descends therefrom to form a "caged" target area for a flying disc or other object. In a preferred embodiment of the assembly, the caged target area is operatively connected to a pedestal and the deflection member or members are a series of tubular shaped impact absorbing members, curved slightly inward, pivotally attached to said top portion and descending into the nest.
