More Information
Summary:A tree stand for holding and supporting a tree having a trunk, the stand having a casing with an inner wall with spirally-curved surfaces, and a guide piece disposed in the center of the casing having guide curves each with a curvature corresponding with the curvature of the spirally-curved surfaces of the inner wall of said casing. Clamping cylinders are disposed inside of the casing between the guide piece and the spirally-curved surfaces of the casing inner wall. A cover is rotatably mounted over the top of the casing and is coupled to each of the clamping cylinders so that when the cover is rotated, the clamping cylinders move within the spirally-curved surfaces of said guide piece and said inner wall of said casing so that said cylinders spirally close upon the trunk of the tree. The cover is also provided with a lock coupled to the casing so that the cover can be locked in place with respect to the casing after the tree trunk is gripped. Gripping recesses are fitted into the top surface of the cover to aid in rotating the cover. The cover includes a central opening for receiving the tree trunk.
