ABSTRACT:
A device for aiding a user in climbing a tree to a vantage point where the device serves as a supporting platform includes a lightweight platform which attaches to the user's feet and is provided with spurs for penetrating into the tree trunk. Stabilizing frameworks project upwardly and rearwardly from the opposite sides of the platform to straddle the tree trunk and two separate devices are provided to attach between these frameworks to pass behind and engage the trunk. One is a rigid bar used normally during climbing and the other is a flexible metal strap below the bar. When a limb is reached by the bar the strap is fixed in place while the bar is swung aside thus allowing the assembly to be elevated so that the bar can then be reattached above the limb so that detachment of the strap allows the user to climb further.
