ABSTRACT:
A dual frame hunting tree stand has a tree stand top (1) and a tree stand bottom (2). Each has a tree engagement member (4) attachable to tree hugging arms (6) extendable pivotally from opposite sides of bottom and top frames (8 and 9). A tree piercing prong (5) is attached rigidly in triangular corner bracing relationship to each side (16) of the inside end (15) of each frame (8 and 9). A desirably sharp distal end (13) of each tree piercing prong (5) is positioned to point towards a center of a tree (3) of average diameter for climbing. Seating (14, 52 and 53), arm rests (54), level adjusters (25, 26, 51 and 56), feet straps (10 and 11), backpack straps (27), selective tree grabbing elements (46, 59, 60 and 61), selective floor surfaces (7, 47 and 57) for the stands and other features are made possible in more advantageous forms as a result of unique structure of this invention.
