ABSTRACT:
A tree stand having a frame adapted to be disposed substantially vertically along the tree trunk. A pair of spaced apart tree engaging members are attached to a top portion of the frame and having a seat connected thereto. A second pair of tree engaging members are pivotally attached along the substantially horizontal axis to a lower portion of the frame for engaging the tree trunk at a second vertical level. A fastening mechanism is provided for extending around the tree trunk and around the frame, for attaching the tree stand to the tree trunk at a desired level. A platform is rigidly attached to the second tree engaging members for permitting the person to stand on the platform when it is in a horizontal disposition. The platform and second tree engaging members are rigidly attached together and are pivotally attached to the frame for permitting the second tree engaging members to be movable between a first position substantially below the horizontal axis and a second at substantially the same level as the horizontal axis, whereby movement of the platform from an elevated position to a horizontal position will cause a lower portion of the frame to be pushed outwardly away from the tree trunk, thereby tightening the fastening means to an extremely tight position. A stop mechanism is provided for preventing the platform from pivoting downwardly beyond a substantially horizontal position.
