  • Patent number: 6102261
    Abstract: A pants hanger, which is mounted on a vertical surface or is used to assemble into pants hanging array for hanging multiple pairs of pants, consists of a fixed horizontally extended base arm, a horizontally extended gripping arm and a spring element biasing the gripping arm against the base arm. The spring element is attached at the center of the gripping arm and allows for rotation of the gripping arm on the spring element to provide a substantially even pressure against an article of clothing supported between the base arm and the gripping arm. The base arm and gripping arm have a recess portion to allow for the increased thicknesses of pants along their seams. The unit may be combined with other like units to provide an array of hangers, disposed either horizontally or vertically.

  • Patent number: 6079598
    Abstract: A pants hanger is comprised of fixed horizontally extending hanging arms and spring elements. Each spring element is attached to one side of a hanging arm and is biased against the opposite side of the adjacent hanging arm. The hanging arms and spring elements may receive a pair of pants or other garment between them. The garment is then supported by the compressive, gripping force of the spring being biased against the adjacent hanging arm. The unit may be combined with other like units to provide an array of hangers, disposed either vertically or horizontally.
