The present invention relates to a dust removal appliance, and more particularly, a handheld cordless dust removal appliance.
Numerous innovations for dusting implements taken singularly or in combination with other related devices have been provided in the prior art that will be described. Even though these innovations may be suitable for the specific individual purposes to which they address, however, they differ from the present invention.
A FIRST EXAMPLE, U.S. Pat. No. 1,433,021, Published/Issued on Oct. 24, 1922, to Michael teaches a device including a casing having an open lower end and a nozzle secured thereover, a plurality of rotatable brushes supported within the nozzle, a vertically disposed shaft mounted in the casing having driving connection with the brushes, a fly wheel carried on the shaft, and a radially disposed bifurcated reciprocal element in the casing having one end slidably received in a portion of the walls thereof. One side of the element has a rack formed thereon. Further included is a pinion engaging the rack and mounted within the casing, a gear mounted in proximity to the pinion, a slop clutch connected to the pinion and engageable with the gear, a second pinion fixedly mounted upon the upper portion of the vertical shaft and meshing with the aforesaid gear, manually operable apparatus arranged upon and exteriorly of the casing engageable with the outer end of the bifurcated element for imparting sliding movement to the same, spring apparatus engaging the casing and a portion of the element for retaining the same in its normal position, a fan fixedly mounted upon the vertical shaft, and a container detachably connected to the casing adjacent an outlet opening therein communicating with the shaft.
A SECOND EXAMPLE, U.S. Pat. No. 2,214,989, Published/Issued on Sep. 17, 1940, to Brand in U.S. class 15 and subclass 158 teaches a feather duster attachment for vacuum cleaners, which includes a flexible conical-shaped member having apparatus at its restricted end of attachment to the tubular handle of a vacuum cleaner and a plurality of detachable annular sections formed on its enlarged end for shortening the same, and a plurality of annularly arranged feathers secured to the flexible member and projecting beyond the latter's enlarged end. The annular sections are detachable one form another to permit the shortening of the enlarged part of the conical-shaped member, whereby the feathers and the enlarged end of the conical-shaped member may be normally maintained in such relative positions with respect to each other that when the feathers break or become worn they still be made to project beyond the enlarged end of the conical-shaped member.
A THIRD EXAMPLE, U.S. Pat. No. 2,747,217, Published/Issued on May 29, 1956, to Stahl in U.S. class 15 and subclass 374 teaches a hollow suction brush for use with a suction cleaner, which includes a tubular shank for attaching the brush to the end of a suction air conduit, and a brush back secured to the inlet end of the shank and having a passage extending therethrough in communication with the tubular shank. The back has concentrically arranged upper and lower flanges surrounding the passage and in spaced planes traversing the passage to provide anchorages for concentric rows of bristles. Further included is and endless row of relatively long and flexible bristles anchored in the upper flange, an endless row of relatively short and stiff bristles anchored to the lower flange, and a flexible tubular shroud member closely spaced inwardly of the row of short bristles. The free ends of the rows of bristles terminate in closely spaced parallel planes with the ends of the shorter bristles terminating above the free ends of the longer bristles, whereby the ends of the shorter bristles may be brought into contact with the surface being cleaned by pressing downwardly on the tool and deflecting the longer bristles. The planes are inclined with respect to planes through the anchored ends of the bristles, whereby the lengths of both rows of bristles gradually varies from the front to the back of the brush, thereby enabling the user to obtain cleaning sections of varying intensity depending on which portions of the rows of bristles are brought into contact with the surface being cleaned.
A FOURTH EXAMPLE, U.S. Pat. No. 5,857,239, Published/Issued on Jan. 12, 1999, to Oh, et al. in U.S. class 15 and subclass 321 teaches a vacuum cleaner including a moisture cleaner device that is attachable and removable. The moisture cleaner device includes a frame providing the circulation track of the moisture cleaner, a working roller and a driven roller mounted sideways in the top and lower part of the frame, a first coupling apparatus for attachment and removal of the lower part of the moisture cleaner to the vacuum suction head section, a second coupling apparatus for attachment and removal of the top part of the moisture cleaner to a connecting pipe, and a moisture cleaner mounted to the surface of the frame. Because the peripheral surface of the working roller is uneven, when the vacuum suction head portion is moved back and forth the working roller and driven roller are rotated, the moisture cleaner thus being operative so that the moisture cleaner contacts the floor as the normal vacuum suction cleaning proceeds.
A FIFTH EXAMPLE, U.S. Pat. No. 6,966,099, Published/Issued on Nov. 22, 2005, to Muller in U.S. class 15 and subclass 393 teaches a duster nozzle for vacuum cleaners, which includes tube carrying a duster at the air flow entrance end. The duster has duster elements that decrease in length, at least partially, along the direction that is transverse to the air flow at the entrance end of the nozzle.
A SIXTH EXAMPLE, U.S. Pat. No. 7,784,137, Published/Issued on Aug. 31, 2010, to Knopow in U.S. class 15 and subclass 22.1 teaches a handheld dust removal devices that selectively utilize vacuum pressure. Preferably, each device includes a small lightweight handle that houses a vacuum assembly having an electric motor and a battery. The device further includes a duster assembly with elongate fiber strands that have elongate voids extending therethrough or thereinto. The vacuum source can be fluidly connected to and draw a vacuum airflow through the duster assembly, for example, through and/or around the fiber strands. In this configuration, the elongate voids of the fiber strands can at least partially direct or influence the travel path of dust, debris, and/or other particulates that are entrained in a vacuum airflow. Some implementations further include an auxiliary vacuum inlet that is adapted and configured for drawing large particles, such as, crumbs, hair, and other things thereinto. The auxiliary vacuum port can be displaced from the duster assembly, e.g., mounted to the handle or elsewhere.
A SEVENTH EXAMPLE, U.S. Pat. No. 7,784,149, Published/Issued on Aug. 31, 2010, to Schwarz, et al. In U.S. class 15 and subclass 344 teaches hand-held dust removal devices that selectively utilize vacuum pressure. Preferably, each device includes a small lightweight handle that houses a vacuum assembly having an electric motor and a battery. The device further includes a duster assembly for removably holding a dusting cloth or cover, whereby it can be used similarly to a conventional duster. The vacuum source can be fluidly connected to and draw a vacuum airflow through the duster assembly, for example, through and/or around the dusting cloth. In some implementations, this is done by drawing the vacuum airflow toward opposing lateral portions of the duster assembly. Some implementations further include an auxiliary vacuum inlet that is adapted and configured for drawing large particles, such as, crumbs, hair, and other things thereinto. The auxiliary vacuum port can be displaced from the duster assembly, e.g., mounted to the handle or elsewhere, as desired.
It is apparent now that numerous innovations for dusting implements taken singularly or in combination with other related devices have been provided in the prior art that are adequate for various purposes. Furthermore, even though these innovations may be suitable for the specific individual purposes to which they address, accordingly, they would not be suitable for the purposes of the present invention as heretofore described.
AN OBJECT of the present invention is to provide a handheld cordless dust removal appliance that avoids the disadvantages of the prior art.
ANOTHER OBJECT of the present invention is to provide a handheld cordless dust removal appliance that is simple and inexpensive to manufacture.
STILL ANOTHER OBJECT of the present invention is to provide a handheld cordless dust removal appliance that is simple to use.
