ABSTRACT:
A tree climbing apparatus comprising a lower support and an upper support wherein each support includes a platform member and brace members in the form of spaced front and back blades with a pair of spaced tubular members connecting the back blade to the platform member. The lower platform includes a foot receiving area designed to cooperate with foot engageable elements to secure an occupant's feet to the platform and a foot support area located rearwardly of the foot receiving area. The upper platform comprises a seat designed to be disposed closely adjacent to the tree such that when the occupant is disposed on the seat with his feet engaged with the foot engageable elements of the lower platform, the occupant's knees are spaced apart straddling the tree. Additionally, when the brace members of the upper and lower supports are supportably engaged with the tree, the lower platform is substantially parallel to the seat of the upper support and the pairs of tubular members of the upper and lower supports are substantially parallel. The foot support area will be displaced further away from the tree than the seat when the upper and lower supports are supportably engaged with the tree.
