US Patent 7373690 Floor cleaning device with collapsible handle

A floor cleaning device having a base assembly and an operating handle selectively movable between an extended position and a collapsed position. The operating handle has a lower handle connected to the base assembly and an upper handle connected to the lower handle. The lower handle is pivotally connected to the base assembly and the upper handle is pivotally connected to the lower handle. The handle is moved to the collapsed position by folding the lower handle downward relative to the base assembly and folding the upper handle relative to the lower handle. The base occupies a floor space defined by an outer periphery of the base assembly, and the lower and upper handles are positioned above the base assembly and do not extend laterally and longitudinally a substantial distance from the outer periphery of the base assembly when the operating handle is moved to the collapsed position.
