Abstract
There is disclosed a variable strength magnetic window cleaning device having a master and slave unit utilizing magnetic force to simultaneously clean both the inside and outside panes of a window. When a user moves the master unit from inside, the slave unit follows the master unit along the outside window, thus cleaning both sides of the window panes simultaneously. A replaceable cleaning surface such as premoistened disposable wipe is secured across the engagement surface area and contacts the window surface to effect the cleaning.
Claims13
A variable strength magnetic window cleaning device having, in combination, a master unit and a slave unit magnetically attracted into close proximity wherein
- the master unit has at least one rare earth magnet operably affixed to a housing thereof,
- the slave unit has at least one magnetically attractable material operably affixed to a housing thereof,
- wherein the at least one rare earth magnet of the master unit magnetically attracts to the magnetically attractable material in the slave unit,
- the master unit and slave unit each have a replaceable cleaning surface situated thereon, the replaceable cleaning surfaces being a disposable wipe premoistened with cleaning solution,
- the master unit and slave unit each have a plurality of attachment members configured to receive and removably secure replaceable cleaning surfaces thereon,
- the housing of the master unit further comprises a handle,
- the housing of the slave unit has a thickness of less than about one inch, and
- the slave unit further comprises a retractable safety catch.
A variable strength magnetic window cleaning device having, in combination, a master unit and a slave unit magnetically attracted into close proximity wherein
- the master unit and slave unit each have at least one rare earth magnet operably affixed to a housing thereof, wherein the at least one rare earth magnet of the master unit magnetically attracts to the at least one mating rare earth magnet in the slave unit,
- the master unit and slave unit each have a replaceable cleaning surface situated thereon,
- the master unit and slave unit each have a plurality of attachment members configured to receive and removably the secure replaceable cleaning surfaces thereon,
- the housing of the master unit and the housing of the slave unit each further comprise a magnet plate operably affixed to the housing and configured to secure the at least one rare earth magnet beneath the replaceable cleaning surface,
- the distance between the magnet plates and the replaceable cleaning surfaces is adjustable by an adjustment mechanism operably affixed to the housing and magnet plate of each the slave unit and the master unit,
- the housing of the master unit further comprises a handle, and
- the housing of the slave unit has a thickness of less than about one inch.
A variable strength magnetic window cleaning device having, in combination, a master unit and a slave unit magnetically attracted into close proximity wherein
- the master unit comprises a handle, a first engagement surface, a first rare earth magnet and a second rare earth magnet and wherein
- the first rare earth magnet and the second rare earth magnet are disposed symmetrically about an X and a Y axis of the first engagement surface,
- the first rare earth magnet has a north polarity facing the first engagement surface,
- the second rare earth magnet has a south polarity facing the first engagement surface,
- the slave unit comprises a second engagement surface and a third engagement surface, a third rare earth magnet and a fourth rare earth magnet and wherein
- the slave unit has a thickness between the second engagement surface and the third engagement surface of less than about one inch,
- the third rare earth magnet and the fourth rare earth magnet are disposed symmetrically about an X and a Y axis of the second engagement surface,
- the third rare earth magnet has a north polarity facing the second engagement surface, the fourth rare earth magnet has a south polarity facing the second engagement surface, such that the first and second rare earth magnets of the master unit magnetically attract the third and fourth rare earth magnets in the slave unit,
- the third and fourth rare earth magnets are disposed asymmetrically with respect to the midpoint about the thickness of the slave unit and along a plane parallel with the second and third engagement surfaces,
- the master unit has a first replaceable cleaning surface situated thereon and in contacting engagement with the first engagement surface, wherein the master unit further has a plurality of attachment members configured to receive and removably the secure the first replaceable cleaning surface thereon,
- the slave unit has a second replaceable cleaning surface situated thereon, and
- the second engagement surface and third engagement surface are configured for receiving the second replaceable cleaning surface.
