  • Convertible treestand for rifle/bow use
    Patent number: 5921348
    Abstract: A treestand is provided which is constructed of two platforms. Both platforms have a supporting frame, one covered with an open grid member, for standing, while the other has a seat for comfortable seating. The seating platform may be mounted to a tree or the like in one of two positions. One position locates the front end thereof in a downward direction. This opens the front end for use in bow hunting. The other or second position is inverted, with the front end located in an upward direction so that it defines a rest surface for rifle hunting. Each platform is supported by a flexible cable that extends from one side of the outer end of the platform, through a side support around the tree to another pivital side support and is connected to the other side of the outer end. The cable itself is adjustable in length to accommodate different diameter trees.
