Abstract:
A double action vacuum cleaner comprising, in combination:a frame including a front extent with a rectangular configuration defined by a front bar, a rear bar and a pair of side bars mounted therebetween, the frame further including a rear extent including a first strip mounted to the rear bar at a central extent thereof and a second strip mounted to the rear bar adjacent to an end thereof with each of the strips of the rear extent extending rearwardly in coplanar relationship with respect to the front extent, the frame further including a pair of wheels rotatably coupled to ends of the strips of the rear extent of the frame and a plurality of dual rollers rotatably mounted along the rear bar of the front extend of the frame between the strips of the rear extent and extending downwardly from the front extent less than a distance in which the wheels extend, the frame further including a bottom face mounted to a lower peripheral edge of the front extent of the frame with a pair of rectangular cut outs formed therein in parallel relationship and a top cover including a front face, a rear face and a single side face defining an open side and an open bottom with a bottom peripheral edge mounted along the bars of the front extent of the frame;a pair of brushes each including a cylinder with a pulley mounted on an end thereof and a plurality of strips of bristles coupled to the cylinders and extending radially therefrom, wherein each strip of bristles has a length which is less than 1/3 a length of the cylinder and has an arcuate configuration, the brushes each rotatably mounted between the side bars of the front extent of the frame with the bristles thereof extending from one of the cut outs of the bottom face of the frame and the pulley exposed by the open side of the top cover;a motor assembly including a motor mounted on the top cover with a rotor having a first end extending from a stator of the motor with a pulley residing above that of a front one of the brushes for engaging the same via a first belt and a second end with a first disk-shaped gear mounted thereon, the motor assembly including a pair of vertically oriented stanchions coupled to inboard ends of the strips of the rear extent of the frame and extending upwardly therefrom and a pair of horizontally oriented support members coupled between top ends of the stanchions and the motor, the motor assembly further including an auxiliary axle rotatably mounted between the support members with a first end having a second disk-shaped gear mounted thereon for engaging the first disk-shaped gear and a second end with a pulley in communication with that of a rear one of the brushes via a second belt, wherein the brushes are rotated in opposite directions upon the actuation of the motor;a rigid upper covering with a first side extent with a first height and a second side extent with a second height twice the first height, the upper covering being removably mounted over the front extent of the frame with the second side extent thereof covering the motor assembly and having a handle mounted thereon for allowing the removal of the upper covering from frame;a handle portion including a pair of elongated bars each having an inboard end rotatably mounted to a central extent of one of the strips of the rear extent of the frame and extending upwardly and rearwardly therefrom, a handle bar mounted between outboard ends of the elongated bars, and a pair of L-shaped brackets coupled to ends of one of the elongated bars for allowing a power cord to be wrapped thereon;a vacuum assembly including a casing having a rigid bottom face and a pair of side faces extending from side edges of the bottom face and coupled along the elongated bars of the handle portion, the vacuum casing further including a removable top face mounted between the elongated bars of the handle portion for defining a closed interior space, the vacuum assembly further including a flexible vacuum tube with a first end in communication with an interior space defined by the top cover of the frame and a second end extending within the interior space of the casing, an inflatable air permeable bag mounted on the second end of the vacuum tube, and a pair of vacuum motors each mounted to the bottom face of the casing with a filtered inlet situated within the interior space of the vacuum casing and an outlet extending through a vent formed in the bottom face of the casing, wherein the vacuum motors suction air from within the top cover and excrete the same from the vacuum casing upon the actuation thereof; anda plurality of controls mounted on the top face of the casing of the vacuum assembly and connected between the vacuum motors and the motor of the motor assembly for selectively actuating the same in an independent manner.
