Abstract:
1. A floor treatment device, comprising: a handle assembly having a pair of handles at a first end and having a second end opposite said first end; a frame rotationally engaged to said second end of said handle assembly; a head assembly, said head assembly rotationally engaged to said frame at one or more pivot points engaged to a planar member; said head assembly having a motor engaged thereto upon said planar member; a drive shaft of said motor communicating through said planar member to operatively engage with a flywheel along a center axis running along a line through said drive shaft and through a center of said flywheel; said flywheel having a first side surface on a first of two sides and a second side surface parallel to the first side surface on a second of said two sides; a bearing assembly engaged to said second side surface, said bearing assembly offset a distance from said center axis; said bearing assembly having a bearing retainer surrounding an engaged bearing; a substantially planar pad drive member engaged on an upper surface to a center area of said bearing, said pad drive member rotatable around a second axis, offset from said center axis, extending along a line from said center area; said pad drive member configured for an engagement with a pad upon a lower surface, opposite said upper surface; rotation of said motor imparting a rotation to said flywheel which imparts rotation and a concurrent orbital motion to said pad drive member and any said pad engaged thereto; a first plurality of weights in a first paired engagement upon opposite respective sides of said two sides of said flywheel; a second plurality of weights in a second paired engagement on said opposite respective sides of said two sides of said flywheel; said second plurality of weights being lighter than said first plurality of weights in an unequal weight distribution; said unequal weight distribution inducing an enhanced thrust motion moment to said pad drive member and enhancing said orbital motion during said rotation of said flywheel; and a rotation of said head assembly, at said pivot point with said frame providing means for said pad and said pad drive member and said motor and said flywheel, to concurrently tilt while in operative engagement, during an encounter with an uneven surface by said pad.
