  • Patent number: 5210973
    Abstract: The present invention is an apparatus for suspending objects such as plants, specifically in a clip and string combination for applying upward direction. One end of the string is fastened to the object to be supported. The string is subsequently placed over a horizontal support wire above the object. The other end of the string is attached to an upper arm of an S-shaped clip, which is bent in two planes and which may alternatively incorporate more adjacent arms. The portion of the string between the object and the support wire is woven between the arms of the clip, which is then pushed downward on the string until it is taut. Periodically, as in the cycle of a plant, the clip can be adjusted along the string.
