ABSTRACT:
A portable, collapsible stand for supporting a cut tree or other generally cylindrical object in a vertical orientation, comprising a plurality of formed leg pair members (14) connected at their centers and radially arrayed to form a central, vertically oriented chamber (32) into which the object is placed. The weight of the object forces the chamber downwards causing the upper extremes (18,24) of the chamber to grasp the object by a spring force. This chamber is then clamped circumferentially to the object for stability. Means for adjusting the apparent vertical orientation of the supported object operate by changing the angle of the leg sections (12,28) and simultaneously tilting the vertically oriented chamber (32) in the required direction.
