  • Patent number: 7531929
    Abstract: A magnetic floating paper towel holder consists of a magnetic stand that has magnetic blocks installed at four corners and four sides and a magnetic paper towel holder which has two magnetic wheels and one magnetic connecting tube. The magnetic polarity of the stand magnetic blocks, the magnetic wheels and the magnetic connecting tube is properly arranged to create a repelling force against each other between the stand magnetic blocks and the magnetic paper towel holder. Therefore, the magnetic paper towel holder floats in air when it is placed on top and in the middle of the magnetic stand.

  • Publication number: 20090078815
    Abstract: A magnetic paper towel holder includes a pair of plates, an inner plate and an outer plate. The outer plate includes a carrier for holding a roll of paper towels, such as an L-shaped rod or a pair of fenestrated blocks and a holding stick. Both the inner and outer plates can be magnetic plates to attract each other, or alternatively one plate is steel and the other magnetic to let the inner plate hold the outer plate repositionably or reversibly in place under a kitchen cabinet or on the side wall of a kitchen cabinet by magnetism without nails or screws or glue.
