  • Patent number: 5060756
    Abstract: A portable treestand for hunters includes a one piece supporting platform cast from a light weight metal, preferably aluminum. The unitary construction of the platform eliminates a large number of fabrication steps and the related fastening techniques and devices used therewith. As a result, the platform is stronger and more rigid, free of many potentially movable joints, and may be made with an irregular pattern. The grate-like pattern of irregular oepnings in the platform provides variable positioning support for different types of archery bows and enhances the ability to camouflage the treestand.
