Abstract
Abstract A compact, easily transportable hunting stand for use by archery hunters or the like is provided which exhibits a high degree of stability when attached to a tree trunk and includes a unique mechanism for permitting precise leveling of the stand. Preferably, the tree stand of the invention includes a platform together with platform mounting means including a leveling screw mechanism permitting the stand to be attached to irregular tree trunks. Further, the mounting structure for the stand platform comprises compression struts and essentially eliminates tensile chains or cables extending about the stand platform; as such, the hunter is allowed complete freedom of movement and the stand seat may be rotated for a full 360 degrees to afford maximum visibility and freedom of action. In its collapsed condition, the stand may be carried on the back of a hunter in the manner of a backpack.
