ABSTRACT:
The subject apparatus is a portable tree stand for observation purposes, and generally comprises, as the basic support member, a triangularly-shaped member, basically formed as a right triangle, when observed from the perspective of a side elevational view. Disposed in the leg of the triangular member which is comparable to the hypotenuese side of such triangular member, is an opening which is adapted to hold a longitudinally and vertically extending shaft member, the upper portion of which is affixed in a pivotal manner to the undersurface of a seat structure. The upright leg of the support structure, which leg is comparable to the vertical leg of the triangle, has upper and lower support elements adapted to engage the outer circumference of a tree trunk so as to affix the apparatus in a vertical position along said tree trunk.
