Abstract
Abstract A climbing apparatus which is primarily used as a climbing deer stand, and which includes a pair of side frame members spaced by and mounted to a wedge support, and further provided with a wedge attached to the wedge support for engaging one side of a tree or pole, and an engaging bar removably carried by the side frames for encircling and engaging the opposite side of the tree or pole to support the apparatus. The climbing apparatus is used in cooperation with a foot support which is generally characterized by a pair of side supports shaped from a single piece of pipe or conduit into a generally U-shaped configuration, with a removable forward brace positioned between the terminus of the legs of the U, and a V-shaped rear brace spaced from the forward brace. The climbing apparatus is used to ascend a tree, post or pole by initially positioning the foot support in engagement with the tree and subsequently positioning the engaging bar of the climbing apparatus around the tree and above the foot support in cooperation with the side frames and wedge support, and first using the foot support as a brace to lift the climbing apparatus, and subsequently using the climbing apparatus as a brace to lift the foot support.
