Abstract: A portable tree stand foldable between transportable and operational positions primarily for use by hunters. The tree stand comprises a rigid, spike-equipped, seat for supporting the hunter above ground adjacent to and in contact with a selected tree, and a cooperating, rigid foot rest adapted to be operationally disposed in spaced-apart, generally parallel relation beneath the seat. The foot rest is pivotally mounted to a rigid, generally U-shaped yoke having upper ends pivotally secured to opposite sides of the seat frame. A pair of spike-equipped jaw members which are pivotally coupled to the seat frame extend rearwardly therefrom and are normally biased apart to a fully open, tree-engaging position. The jaw members include integral, outwardly diverging locking arm portions which are adapted to be drawn together by the hunter with a rope during stand installation to forcibly compress the jaw members in binding, substantially circumferential engagement with the selected tree.
