ABSTRACT:
A tree stand and/or climbing device of multiple designs preferably using industrial machinery style belts to provide maximum strength and gripping power. The belts are preferably made of tough rubber compounds and inlaid with various high strength fibers and other materials. The belts preferably have a uniform teeth pattern, which provide flexibility and allow the belt to conform to uneven surfaces on a tree. The teeth and flexible nature of the industrial belts provide a mechanism for securing the belts and adjusting the length for a wide-range of tree diameters. Dual or multiple belt or fastening device designs allow individuals to climb past limbs or other obstacles and maneuver around forks in trees. The invention also relates to climbing steps to serve as hand grips and/or foot rests during climbing. The invention also concerns a slip-lock locking device.
