  • Patent number: 5575447
    Abstract: A multiple strand pot hanger, and in particular, a three-strand pot hanger is comprised of a multiple strand or wire harness coupled to a ring having a plurality of radially extending ears or connection segments coupled to the harness. The ring has an inner diameter which provides an interference fit with the body of the flower pot placed into the pot hanger. The ring may have a permanent nonadjustable inner diameter or may be temporarily and adjustably joined at its opposing ends to accommodate a wide range of pot diameters. In the case of the nonadjustable ring, the opposing ends may be flash welded or connected together by means of a wire wrap. The connection points spaced along the ring and radially extending from it for connection to the wire harness may be comprised of either U-shaped extensions integrally formed as part of the ring, overhand loops, or dihedral radially extending loops in the case where the ring is made from a flat resilient band.
