ABSTRACT:
A tree climber comprising a pair of climbing members, adapted to be affixed to the user's feet by quick release straps. Each climbing member includes a support arm extending forward from a platform portion and terminating at one end of a moveable hook shaped clamping portion which engages the back side of the pole. Several embodiments show a clamping portion which is adjustably affixed to the terminus of the support arm with either a slidable collar and tube configuration or a clamped configuration. Another embodiment includes a slidable collar affixed to the platform portion, the support arm extending therethrough to a desired length corresponding to the diameter of the pole. The adjustable clamping portion of any of the embodiments may be used in combination with the extendable support arm to accommodate a wide range of tree trunk or pole diameters and to easily traverse protruding limbs which would otherwise arrest further vertical progress. A strapping assembly secures the tree climber to the tree at the desired elevation. In its collapsed configuration the climbing members are nested and easily transported or stored.
