Definitions
- This invention relates generally to methods and apparatuses for collecting particulates from a flow of air transported through a vacuum cleaner.
- vacuum cleaners are widely available, and are useful in a number of cleaning applications.
- One type of vacuum cleaner commonly known as the upright vacuum cleaner, is f equently used in both residential and commercial settings to remove particulates of various sizes from floor surfaces such as carpeting, wood flooring, or linoleum.
- FIG. 1 A typical upright vacuum cleaner according to the prior art is shown in Figure 1.
- the upright vacuum cleaner 10 is comprised of a handle assembly 112 with a grip 118 mounted thereon.
- a collector bag assembly 120 is generally frontally positioned on the handle assembly 112 that serves as a receptacle for the collection of particulate matter.
- the vacuum cleaner 10 is further comprised of a wheel-mounted head assembly 20 pivotally coupled to the handle assembly 112 by a pivot 114.
- the head assembly 20 may be of any suitable construction, but is generally comprised of a housing with a top portion 202 and front and rear walls 200 and 208 that are joined by side walls 204 and 206.
- a protective bumper 210 is generally peripherally disposed on the head assembly 20 and projects outwardly from a lower edge of the front wall 200 and the side walls 204 and 206 to protect walls and room furnishings from potentially damaging impacts.
- FIG. 2 shows a cutaway side view of the head assembly 20 of the prior art vacuum cleaner 10.
- the head assembly 20 is further comprised of a transversely extending rotating cylindrical brush 216 that has a plurality of brush elements 218 disposed thereon.
- the cylindrical brush 216 is generally supported by bearings (not shown) positioned in the side walls 204 and 206, and is rotationally driven by a motor (also not shown) recessed within the head assembly 20.
- a bottom panel 211 is suitably mounted beneath the housing walls that generally carry a rearwardly disposed set of support wheels 212, and a forwardly disposed set of support wheels 213.
- the bottom panel 211 is further comprised of an intake nozzle 115 surrounding the rotating brush 216, and positioned substantially close to a floor surface 110.
- the head assembly 20 is further comprised of a motor-driven blower 220 that is recessed within the head assembly 20 that has an intake opening 222 that is suitably fluidly coupled to the intake nozzle 115.
- the blower also has an exhaust outlet 224 that is suitably fluidly coupled to the outer bag assembly 120.
- the user of the upright vacuum cleaner grasps the grip 118 on the handle assembly 112 and reciprocally translates the head assembly 20 across the floor surface 110 while the cylindrical brush 216 rotates and brushes the surface 110 and the blower 220 is developing suction at the intake nozzle 115. Effective removal of particulate matter from the floor surface 110 is thus obtained through the combination of brushing the surface 110 to loosen embedded particulates, suctioning the loosened particulates away from the floor surface 110, and transferring the particulate matter into the collector bag assembly 120.
- a rotating brush positioned within a head assembly is disposed immediately adjacent but rearwardly of a front wall of the head assembly.
- the front wall is resiliently yieldable to enable the brush to more effectively clean the near corner region when the front wall of the head assembly is pushed against the baseboard, or wall of a room.
- the front wall of the head assembly is structured to move upwardly and away from the rotating brush when the head assembly is pressed against a baseboard, or room wall.
- a front edge cleaning device for an upright vacuum cleaner comprises a flexible, resilient member frontally disposed on the head assembly of an upright vacuum cleaner.
- the front edge cleaning device includes an elongated section having an upper section and a lower section with front and a rear faces, the rear face of the upper section being attached to the front wall of the vacuum cleaner and the lower section extending downwardly from the upper section and having the front face of the lower section beveled inwardly towards the rear face of the lower section to form an apical lower edge spaced apart from the floor with air openings positioned along the apical lower edge and projecting through the lower section.
- the front edge cleaning device includes an elongated section having an upper section and a lower section with front and rear faces, the rear face of the upper section being at least partially attached to the front wall of the vacuum cleaner and the lower section extending downwardly from the upper section and having the front face of the lower section offset inwardly towards the rear face of the upper section to form a lower offset edge spaced apart from the floor with a plurality of air openings positioned along the lower offset edge and projecting through the lower section.

- the present invention is generally directed to a frontally positioned edge cleaning device for use with an upright vacuum cleaner.
- Many of the specific details of certain embodiments of the invention are set forth in the following description and in Figures 3 through 11 to provide a thorough understanding of such embodiments.
- One skilled in the art will understand, however, that the present invention may have additional embodiments, or that the present invention may be practiced without several of the details described in the following description.
- FIG. 3 is a horizontal frontal view of an edge cleaning apparatus 30 according to an embodiment of the invention.
- the edge cleaning apparatus 30 is comprised of an elongated, substantially flexible and resilient straight portion 300 disposed on the lower edge of the front wall 200 of the head assembly 20.
- the edge cleaning apparatus 30 also has substantially flexible and resilient curved side portions 301 that are joined to each end of the straight portion 300 that at least partially extend onto the lower edges of the side walls 204 and 206 of the head assembly 20.
- any suitably flexible and resilient material may be used to form the edge cleaning apparatus 30, preferably polyvinylchloride, or a polyurethane material is used.
- the straight portion 300 and curved side portions 301 are preferably formed as a single unitary structure.
- the straight portion 300 and curved side portions 301 have a substantially flat upper portion 313 and a lower beveled portion 312 that projects downwardly from the flat upper portion 313 toward a floor surface 306 to define a lower edge 304 that is substantially parallel with the floor surface 306.
- the lower beveled portion 312 is beveled inwardly towards the intake nozzle 115 at a bevel angle 311, which is preferably approximately 7.5 degrees, although other inwardly projecting angles may be employed.
- the lower edge 304 is separated from the floor surface 306 by a distance d to form an air flow gap 302.
- the air flow gap 302 substantially restricts the flow of air into the intake nozzle 115 within the head assembly 20 to advantageously increase the air velocity through the air flow gap 302 thus improving front edge cleaning performance.
- the lower beveled portion 312 is further comprised of a plurality of openings 310 positioned along the lower edge 304 that are spaced apart along the frontal length of the lower beveled portion 312 and project through the beveled portion 312.
- the openings 310 advantageously permit particulate matter that is too large to be passed through the air flow gap 302 to be ingested into the intake nozzle 115, while preventing other items, such as power cords attached to appliances, or to the machine itself, from coming into contact with the rotating brush 216 (as shown in Figure 2). Additionally, the openings advantageously allow air to continue to flow into the intake nozzle 115 if the gap 302 becomes too restrictive to permit sufficient air flow into the head assembly 20.
- the gap 302 may become too restrictive to air flow if the distance ( becomes too small, either by height adjustments of the head assembly 20 relative to the floor surface 306, or by irregularities in the floor surface 306.
- the openings 310 are preferably substantially rectangular in shape with the inner corners 309 and the lower corners 308 having a superimposed radius, but the openings 310 may be semicircular, triangular, or may have still other regular shapes.
- the position of the openings 310, and the total number of openings 310 positioned along the lower edge 304 may be varied to optimize edge cleaning performance.
- Figure 5 shows a side view of the edge cleaning apparatus 30 disposed on a head assembly 20 that is positioned adjacent to a wall surface 402.
- the inwardly projecting bevel angle 311 of the lower beveled portion 312 advantageously allows a clearance space 400 to be formed when the flat upper portion 313 contacts the wall surface 402.
- the clearance space 400 advantageously allows air to be suctioned into the intake nozzle 115 from the near corner region 225 by permitting air to flow through the clearance space 400 and into the intake nozzle 115.
- the air velocity in the clearance space 400 may be advantageously controlled through the preferential selection of the width of the air flow gap 302, and the inwardly projecting bevel angle 311 of the lower beveled portion 312, in order to optimize edge cleaning performance.
- a rear plan view of the edge cleaning apparatus 30 shows the edge cleaning apparatus 30 being further comprised of a resilient frontal retaining portion 500 that is positioned away from the rear surface of the straight portion 300, and extending substantially along the length of the rear surface of the straight portion 300.
- the frontal retaining portion 500 further extends from a medial position on the rear surface of the straight portion 300 to substantially the upper edge 509 of the straight portion 300.
- the frontal retaining portion 500 is attached to the rear surface of the straight portion 300 by a resilient frontal coupling portion 502 to form a gap 510 between the rear surface of the straight portion 300 and the frontal retaining portion 500.
- Reinforcing portions 508 are disposed in the gap 510 at selected intervals and extend from the frontal coupling portion 502 to the upper edge 509 to further reinforce the frontal coupling portion 502.
- the curved side portions 301 are similarly comprised of a side retaining portion 504 that is attached to the rear surface of the curved side portion 301 by a side coupling portion 506.
- Figure 7 shows a top view of the edge cleaning apparatus 30 that further depicts the frontal retaining portion 500 and the frontal coupling portion 502 disposed on the rear surface of the straight portion 300. Also shown in Figure 7 is a further depiction of the side retaining portion 504 and side coupling portion 506 that are disposed on the rear surface of the curved side portions 301.
- Figure 8 shows a cross sectional view of the edge cleaning apparatus 30, corresponding to the cross sectional cut shown in Figure 6, disposed on the front wall 200 of the head assembly 20.
- a front wall mounting slot 551 projects through the front wall 200 and is suitably dimensioned to receive the frontal coupling portion 502 yet too small to allow the frontal retaining portion 500 to pass through when in a non-deformed condition.
- the front wall mounting slot includes perpendicular intersecting slots (not shown) suitably dimensioned to receive the reinforcing portions 508.
- the frontal retaining portion 500 After the frontal retaining portion 500 has passed entirely through the slot 551, the frontal retaining portion 500 returns to its undeformed shape to lock the straight portion 300 in place.
- Side portions 301 are similarly installed on the side walls 204 and 206 by resiliently deforming the side retaining portion 504 and urging it through suitably dimensioned slots (not shown) in the side walls 204 and 206 of the vacuum cleaner head assembly 20. After the side retaining portion 504 has passed through the slot, it similarly returns to its undeformed shape to lock the side portions 301 in place.
- the present embodiment describes the use of retaining portions disposed on the rear surfaces of the edge cleaning apparatus 30, other attachment methods may be used.
- the straight portion 300 and curved side portions 301 may be adhesively bonded to the front wall 200, and side walls 204 and 206 of the head assembly 20.
- the straight portion 300 and curved side portions 301 may be attached to the front wall 200, and side walls 204 and 206 of the head assembly 20 by suitably recessed screws, or other fastening devices.
- Figure 9 is a horizontal frontal view of an edge cleaning apparatus 40 according to another embodiment of the invention.
- the edge cleaning apparatus 40 is comprised of an elongated, substantially flexible and resilient straight portion 300 disposed on the lower edge of the front wall 200 of the head assembly 20.
- the edge cleaning apparatus 30 also has substantially curved side portions 301 that are joined to each end of the straight portion 300 that at least partially extend onto the lower edges of the side walls 204 and 206 of the head assembly 20.
- any suitably flexible and resilient material may be used to form the edge cleaning apparatus 40, preferably polyvinylchloride, or a polyurethane material is used.
- the straight portion 300 and curved side portions 301 are preferably formed as a single unitary structure.
- the straight portion 300 and curved side portions 301 have a substantially flat upper portion 313 and a lower offset portion 600 that projects downwardly from the flat upper portion 313 toward a floor surface 306 to form a lower edge 304 that is substantially parallel with the floor surface 306.
- the lower offset portion 600 is displaced inwardly towards the intake nozzle 115 a distance D.
- the lower edge 304 is separated from the floor surface 306 by a distance d to again form an air flow gap 302.
- the edge cleaning apparatus 40 will similarly allow substantial air movement in the near corner region, thereby increasing edge cleaning performance.
- the various embodiments of the edge cleaning apparatus are durable, resilient devices capable of sustaining blows with no effect on performance.
- the edge cleaning capability of the various embodiments may be adapted to a variety of floor surfaces by adjusting the height of the lower edge of the embodiments above the floor surface through conventional height adjustment devices commonly employed to set the height of the rotating brush.
- the various embodiments of the edge cleaning apparatus are fabricated from a resilient material, the possibility of damage to underlying floor surfaces, or to baseboard surfaces, walls or furniture objects is minimized.
