  • 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.
