ABSTRACT:
The present disclosure relates to tree stands which grasp upright columnar members for example, trees, poles, which are arranged to facilitate climbing and adjusting the height of the tree stand to a desired level and angle. When assembled as a cart, the invention consists of an upper climbing member or frame, lower climbing member or frame, a mechanical-interlocking system, an axle, wheels and a wheel attachment device. The two-climbing-member tree stand may be of a manually adjusting type or of a self-adjusting type which permit adjustment of the spacing of the grasping members so as to effect adjustment of the angle of each tree climber relative to the upright columnar member.
