  • Patent number: 4553634
    Abstract: A tree stand having a platform, preferably separated in a front-to-rear dimension to form a pair of side-by-side hinged platform sections for swinging movement between an operative coplanar position and an inoperative collapsed position, a pair of opposed side supporting arms pivotally mounted to the side edges of the platform and projecting upward and rearward in an operative position for straddling a tree against which the rear edge of the platform is mounted, and a cross bar connectable to the rear ends of the supporting arms behind the tree for securing the tree stand to the tree trunk in operative position. The support arms are pivotally connected to the side edge portions of the platform in such a manner that they may be swung between the operative position and an inoperative position in which the support arms are colinear with the side edges of the platform member, so that the tree stand may be folded to a compact position for transport on the back of the operator.
