  • Patent number: 5303889
    Abstract: A foldable wire holder for a plastic bag is disclosed to hold the bag in a vertical position with its mouth snagged in a fully open position on a wire framework formed by a horizontally disposed bag holding frame and an upper portion of an upright supporting framework for the bag holding frame. The wire holder is portable and, in one embodiment, may simply be thrust into the ground where it is to be used, for example, to collect leaves, grass clippings, or other discrete matter. The legs of the supporting frame are provided with stub ends and a lateral support member which sets their depth and keeps the bag holding frame in a horizontal plane while the bag is filled. In another embodiment, a foldable base is provided which is a mirror image of the bag holding frame. Angulation of the pivot on the supporting frame, or of the ends of the bag holding frame, is essential to position the bag holding frame in the horizontal position.
