Claim Text:
1. An adjustable platform assembly for attaching to a tree, comprising: a tree hugging subassembly comprising a first tree engaging member and a second tree engaging member connected to said first tree engaging member by a hinge that allows free pivotal movement of said first and second tree engaging members relative to each other, said first and second tree engaging members each having a generally arcuate shaped surface on a side facing the tree to accommodate a curvature of the tree, said arcuate shaped surface being covered by a padded material for engaging the tree to prevent damage to the tree; a first strap fastener for securing said tree hugging subassembly to a tree, said first strap fastener has one end connected to a side edge of said first tree engaging member and another end connected to a side edge of said second tree engaging member; a second strap fastener having one end connected to the side edge of said first tree engaging member and another end connected to the side edge of said second tree engaging member, said first and second strap fasteners being spaced apart from each other; a first frame member attached to said tree hugging subassembly by attachment only to said first tree engaging member, said first frame member being pivotally adjustable relative to said first tree engaging member about a first axis that extends generally perpendicular to an axis of the tree and perpendicular to a first plane; a second frame member attached to said first frame member, said second frame member being adjustable relative to said first frame member about a second axis that extends generally parallel to said first plane; and a platform attached to said second frame member, whereby said platform can be adjusted to a desired orientation by adjusting said first frame member relative to said first tree engaging member and by adjusting said second frame member relative to said first frame member, wherein said first frame member is attached to said first tree engaging member by a threaded member that extends through a bore in said first frame member into a threaded receiver on said first tree engaging member; and wherein said threaded receiver is fixed on said first tree engaging member, and said threaded receiver has an inner threaded surface that mates with said threaded member and a multi-sided outer surface that mates with a corresponding multi-sided inner surface in the bore of said first frame member to lock said first frame member against rotation about said first axis, whereby said multi-sided outer and inner surfaces can be mated in a plurality of positions or rotation of said first frame member relative to said first tree engaging member to provide indexed adjustment of the platform assembly about said first pivot axis.
