ABSTRACT:
The present invention provides a weight bearing device adapted to support weighted objects upon vertically extending pole-shaped objects such as wooden poles and trees. The device comprises an anchoring strap and a forked unit fitted with a leveraged support frame, a forked end member having terminal penetrating tips and radially extending downwardly and outwardly from the support frame. The strap is mounted at a pivotal site along the support frame. In operational use, the penetrating tips are aligned onto the pole-shaped object with the strap being looped about the pole and adjustably anchored onto the mount under sufficient strap tension to allow the major longitudinal axis of the forked unit frame to extend upwardly and outwardly therefrom. The adjusted strap tension should, however, be sufficient to permit the strap when further tightened by the leveraged action of the forked unit to form a pivotal anchoring site about the strap mount. By applying a downward force onto the support frame, the penetrating tips will swing inwardly and upwardly about the pivotal mount site causing the strap to grippingly tighten about the object and the tips to penetrate the object and thereby firmly anchor the weight bearing device thereto.
