Abstract: A playground appliance comprising a plurality of support members from which are suspended net units to form a non-planar playing surface that children can climb. The support members include vertical posts supported on the ground by anchoring devices. Each anchoring device includes a ground engaging support plate having a surface substantially exceeding a transverse dimension of the vertical post. Ground penetrating spike members are driven through the support plate to stabilize the post. The assembly is easy to erect and can sustain heavy loading without collapsing.
