  • Anti-rotational outdoor shelf
    Patent number: 5156096
    Abstract: An anti-rotational outdoor shelf (1) where an unobstructed surfaces (3) is supported from below. Multi-dimensional stability is provided by legs (4) angled with respect to a central axis (C--C) to transform load forces into stabilizing forces. Undesirable tipping, rotation, and revolution about a support member are addressed. A gap between surfaces (3) and the natural support, such as a tree, together with smooth legs (4) allows vertical sliding to avoid the need for tight attachment. The design compacts when not temporarily installed through slidable connections.
