  • Patent number: 8356381
    Abstract: A structure for automatically rotating a spiral rod is provided. The structure allows a dusting cloth to be turned into a spiral shape along the spiral rod by rotating a rotating element, and, while the rotating element is being rotated, a torsion spring generates a restoring torque. Once the rotating element is no longer rotated, a pulling element pressing against the teeth inside the rotating element retains the rotating element and thus keeps the dusting cloth in the spiral shape. When the pulling element is subsequently pulled away from the teeth of the rotating element, the rotating element automatically rotates in the reverse direction due to the restoring torque of the torsion spring.

  • Patent number: 7788759
    Abstract: A standing duster article consisting of a dusting portion and a spiral handle, wherein the dusting portion is comprised of a segmented intermingled yarn layer, a hot-meltable nonwoven fabric layer, a smooth nonwoven fabric layer, and a nonwoven/woven fabric layer; the segmented intermingled yarn layer is interleaved between the hot-meltable nonwoven fabric layer and the smooth nonwoven fabric layer; the nonwoven/woven fabric layer is further superimposed on the smooth nonwoven fabric layer; a hot-pressing process is carried out to fuse the segmented intermingled yarn layer, the hot-meltable nonwoven fabric layer, the smooth nonwoven fabric layer, and the nonwoven/woven fabric layer; the resulted lamination after fusion is cut by a cutting apparatus, so as to generate a slit in the middle to form the dusting portion which is easy to be folded to form two elongated openings; and a spiral end of the spiral handle is inserted into the openings to form the duster article with the spiral dusting portion.
