  • 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.

  • Patent number: 5234076
    Abstract: A hunter's tree stand, typically of two platform construction. Both platforms have a supporting metal frame, one covered with an open metal grid for standing, and the other having a web fabric seat for comfortable seating. Each platform is supported by rigid, folding side rails, which fold for easy storage. A flexible, encased steel cable extends from one side rail around the trunk of the tree, and is fastened to the other side rail, and adjusted in length by a snap ring clip, a blunt round edge toothed blade extends from the metal frame, and, in combination with the encased cable, holds the stand securely to the tree under load, but without penetrating the bark or otherwise injuring the tree. The encased cable and folding supports conform to the shape of the tree, and give the user a secure feeling both while climbing and while sitting or standing in the elevated stand.
