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. A rigid, downwardly extending V-shaped brace pivotally associated with the seat terminates in a lower spike for penetrating the tree. A stabilizer operationally, generally horizontally extending between the V-brace and the yoke reinforces the stand and assures penetration of the tree by the V-brace spike. A preferably multi-segment ladder extends between the bottom of the yoke and ground and functions as a support stanchion, and the ladder may be manually grasped by the hunter to manipulate the tree stand facilitating ease of installation. Preferably an elongated rope having one end permanently attached to one of the jaw member locking arm portions facilitates rapid jaw member compression and thus convenient tree stand erection.
