ABSTRACT:
A device for climbing trees, poles, ship masts or similar uprights and providing a platform upon which the climber may sit for observation or work purposes after climbing comprises a clamping part and a platform part. The clamping part provides a C-shaped arrangement of adjustable size formed of two telescoping elements held at an obtuse angle to the platform part. In use, the platform part is strapped to the user foot and the clamping part extends around the tree or like to be climbed. The user can virtually walk up the tree, pole, etc. and because the clamping part has a side opening, tree limbs, or similar obstructions do not impede the climbing.
