Description




TECHNICAL FIELD




This invention relates generally to methods and apparatuses for collecting particulates from a flow of air transported through a vacuum cleaner.




BACKGROUND OF THE INVENTION




Conventional 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 frequently used in both residential and commercial settings to remove particulates of various sizes from floor surfaces such as carpeting, wood flooring, or linoleum.




A typical upright vacuum cleaner according to the prior art is shown in FIG.


1


. As shown therein, the upright vacuum cleaner


10


is comprised of a wheel-mounted head assembly


100


that is further comprised of an intake nozzle


115


positioned close to a floor surface


110


. A blower (not shown) is generally located within the head assembly


100


that takes in a flow of air and entrained particulates through the intake nozzle


115


, and discharges the flow of air into an outer bag assembly


120


that traps the entrained particulates while allowing the flow of air to be passed through the surface of the outer bag assembly


120


and returned to the surroundings. A handle assembly


112


extends generally upwardly from the head assembly


100


and is pivotally attached to the head assembly


100


by a pivot


114


so that a user can grasp and move the handle


118


while in a standing or walking position to conveniently and effectively move the head assembly


100


across the floor surface


110


.




With reference still to the prior art upright vacuum cleaner depicted in

FIG. 1

, the outer bag assembly


120


is further comprised of an inner filter bag (not shown) positioned within the outer bag assembly


120


. The inner bag is generally made from a paper material with relatively fine interwoven fibers to trap particulates transported into the inner bag by the flow of air. When the inner bag becomes filled with particulate matter, it is removed from the machine and discarded. The outer bag assembly


120


is generally made from a durable, woven, air permeable fabric that provides mechanical support to the relatively flexible inner bag, and generally protects the inner bag from tears or punctures that would allow the particulates trapped within the inner bag to escape. Additionally, the outer bag assembly provides secondary filtration that augments the primary filtration provided by the inner bag.




One difficulty encountered in the use of upright vacuum cleaners is providing access to the interior of the outer bag assembly so that the inner bag may be conveniently removed. Since the inner bag is substantially filled with fine particulate matter that may be easily scattered if the inner bag is mishandled during the removal process, the inner bag is generally slowly and carefully removed from the interior of the outer bag assembly to minimize particulate scattering. Outer bags used in some prior art upright vacuum cleaners have bag openings that extend longitudinally along the length of the bag, with a closure device such as a zipper, or VELCRO® to close the bag opening. As a consequence, to access the inner bag, the user must usually place the machine on a horizontal surface with the outer bag assembly oriented horizontally, or alternatively, if the machine is left in an upright position, remove the inner bag while in a kneeling position.




An additional difficulty encountered in the use of upright vacuum cleaners is providing an outer bag assembly that affords a firm and durable mechanical support for the inner bag. For the upright vacuum cleaner to remove particulates with maximum effectiveness, the inner bag must be permitted to fully inflate when the flow of air is established. Accordingly, the outer bag assembly must impart sufficient support to the inner bag to allow full inflation of the bag without developing folds, or other internal obstructions that would disrupt the flow of air within the inner bag. Prior art outer bag assemblies, as shown in

FIG. 1

, are generally fabricated from lightweight, substantially flexible air permeable fabrics, and consequently may not provide the required mechanical support. Furthermore, the outer bag assembly must substantially protect the inner bag from tearing or other physical damage that may result from physical abrasion encountered in normal use. For example, with reference again to the prior art device shown in

FIG. 1

, when the wheel-mounted head assembly


100


is moved substantially under furniture objects that are close to the floor surface


110


such as beds, chairs or tables, the handle


112


must usually be significantly lowered to allow the head assembly


100


to be moved under the object. Since the outer bag assembly


120


is generally frontally positioned on the handle assembly


112


, the frontal surface of the outer bag assembly


100


may repeatedly contact the furniture object, subjecting the outer bag assembly


100


to physical wear that may ultimately affect the integrity of the outer bag assembly


100


.




SUMMARY OF THE INVENTION




An outer bag assembly for an upright vacuum cleaner is disclosed. The outer bag assembly comprises a flexible, air permeable enclosure having an internal volume adapted to contain a disposable inner bag. The outer bag assembly is further comprised of an upper end adapted to provide access to the internal volume through a closure device, and an opposite end attached to a handle assembly through a bag clip assembly. In one aspect, the closure device includes a zipper disposed along an upper front peripheral edge of the outer bag assembly that allows a front panel of the bag assembly to be partially released. In another aspect, the closure device includes a zipper disposed along an upper front peripheral edge, and a zipper disposed along an upper rear peripheral edge of the outer bag assembly that allows a top panel of the outer bag assembly to be partially released. In still another aspect of the invention, the closure device includes a bag cap comprised of resilient thermoplastic sections hinged to allow access to the internal volume of the bag assembly. In a further aspect, a bag clip assembly adapted to retain the opposite end of the bag is disclosed.

DETAILED DESCRIPTION OF THE INVENTION




The present invention is generally directed to an outer bag assembly 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

FIGS. 2 through 14

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. 2

is an isometric view of an outer bag assembly according to an embodiment of the invention. The outer bag assembly


20


is comprised of a front panel


22


, a pair of side panels


24


, a top panel


28


, and a back panel


38


. A bag clip assembly


26


engages the lower edges of the front panel


22


, the back panel


38


, and the side panels


24


to enclose the lower portion of the outer bag


20


. The bag clip assembly


26


will be described in greater detail below. The front panel


22


, back panel


38


, and side panels


24


are further attached along an adjacent front peripheral edge


34


and an adjacent back peripheral edge


36


to define an enclosed interior space


42


. The front panel


22


, back panel


38


, side panels


24


and top panel


28


are fabricated from any suitable, air permeable fabric material, such as a woven nylon fabric, a melt-blown and/or spun bond polypropylene or polyethylene material, or other equally suitable materials.




Still referring to

FIG. 2

, a zipper


32


is disposed along a portion of the front peripheral edge


34


of the front panel


22


to provide a releasable attachment between a portion of the front panel


22


and portions of the side panels


24


and top panel


28


. Alternatively, the zipper


32


may be disposed on the top panel


28


and the side panels


24


at an intermediate edge


23


located very close to the front peripheral edge


34


. Although

FIG. 2

depicts a zipper


32


attaching the front panel


22


to the top panel


28


and the side panels


24


, other means for releasably attaching the front panel


22


to the top panel


28


and the side panels


24


exist. For example, the zipper


32


may be replaced by hook-and-loop closures, such as VELCRO®. Alternatively, a pair of zippers may be disposed along the front peripheral edge


34


that share a common zipper track. Still other means for releasably attaching the front panel


22


to the top panel


28


and the side panels


24


may comprise snaps or buttons disposed along the front peripheral edge


34


.




As best seen in

FIG. 3

, the position of the zipper along the front peripheral edge


34


of the front panel


22


advantageously permits the front panel


22


to be partially detached from the side panels


24


and top panel


28


to access to the interior space


42


. Unlike prior art outer bag assemblies that feature a zipper disposed along a midline of the side panels


24


and the top panel


28


, the outer bag assembly


20


has the zipper


32


along the peripheral edge


34


of the front panel


22


, or alternatively along the intermediate edge


23


located very close to the front peripheral edge


34


. When the zipper


32


is unzipped, a portion of the front panel


44


partially overlaps the front panel


22


, enabling the user to access the interior region


42


without bending the side panels


24


. As a result, the user is more easily able to access an inner bag located within the interior space


42


, which minimizes the risk of particulate scattering. Moreover, because the side panels are not substantially bent during this process, the side panels


24


experience less flexure during the opening procedure. Consequently, the side panels


24


experience less wear, and the outer bag assembly


20


retains its original shape and appearance for a greater period of time. In addition, when the material is not substantially bent, it is less prone to fatigue that may cause leaks, thus preserving the secondary filtration capability of the outer bag assembly


20


.





FIG. 4

is an isometric view of an outer bag assembly according to another embodiment of the invention. The outer bag assembly


50


is comprised of a front panel


22


, a pair of side panels


24


, an arcuate top panel


58


, and a back panel


38


. As in the previous embodiment, a bag clip assembly


26


engages the lower edges of the front panel


22


, the back panel


38


, and the side panels


24


to enclose the lower portion of the outer bag


20


. The front panel


22


, back panel


38


, and side panels


24


are further attached along an adjacent front peripheral edge


34


and an adjacent back peripheral edge


36


to define an enclosed interior space


42


. The front panel


22


, back panel


38


, side panels


24


and top panel


58


are fabricated from any suitable, air permeable fabric material.




With reference still to

FIG. 4

, a pair of zippers


52


and


54


is disposed along a portion of the front peripheral edge


34


and the back peripheral edge


36


. The zippers


52


and


54


provide a releasable attachment between a portion of the front panel


22


and a portion of the back panel


38


that permits the top panel


58


to be partially released from the front panel


22


and the back panel


38


. Although

FIG. 4

depicts zippers


52


and


54


as the means to release the top panel


58


, other equally alternative means for this releasable attachment exist, such as hook-and-loop closures (VELCRO®), or by snaps or buttons disposed along the front peripheral edge


34


and the back peripheral edge


36


.




Turning now to

FIG. 5

, the top panel


58


is further comprised of a flap


62


that at least partially overlaps the side panel


24


when the zippers


52


and


54


are moved to the fully closed position. As best seen in

FIG. 6

, the flap


62


is also comprised of a closure


60


that holds the flap


62


securely to the side panel


24


when the zippers


52


and


54


are fully closed. Although a hook-and-loop closure such as VELCRO® may be used to secure the flap


62


to the side panel


24


, other closure means are available, such as snaps


64


, as shown in

FIG. 6A

, or buttons


63


, as shown in FIG.


6


B. As shown in

FIGS. 5

,


6


,


6


A and


6


B, the outer bag assembly


50


is further comprised of a tie pull


56


that joins a zipper pull


57


to a zipper pull


58


. The inclusion of the tie pull


56


joining the zipper pull


57


to the zipper pull


58


advantageously permits the zippers


52


and


54


to be unzipped simultaneously to access the interior


42


of the bag


50


.





FIGS. 6

,


6


A and


6


B further show the top panel


58


of the outer bag assembly


50


in a partially released condition after the zippers


52


and


54


have been partially unzipped. As shown therein, the location of zippers


52


and


54


along the front peripheral edge


34


and the back peripheral edge


36


advantageously permit the top panel


58


to be partially detached from the front panel


22


, the back panel


38


, and the side panels


24


, to allow a portion of the top panel


58


to partially overlap a side panel


24


, enabling the user to more easily access the interior region


42


of the outer bag assembly


50


without flexing the side panels


24


. As a consequence, the original shape and appearance of the outer bag is retained for a greater period of time.





FIG. 7

is an isometric view of an outer bag assembly according to yet another embodiment of the invention. The outer bag assembly


65


is comprised of a front panel


22


, a pair of side panels


24


, an arcuate bag cap


70


, and a back panel


38


. The front panel


22


, side panels


24


and back panel


38


are fabricated from any suitable, air permeable fabric material. The bag cap


70


is further comprised of a front section


71


and a rear section


72


that are hingeably connected at hinge points


72


so that the bag cap


70


may be positioned in a closed position, as shown in

FIG. 7

, or in an open position, as best seen in FIG.


8


. The bag cap


70


may be fabricated from any suitable resilient thermoplastic material.




With reference now to

FIG. 7

, the front section


71


of the bag cap


70


is sealably attached to the side panels


24


, and to the front panel


22


along the front peripheral edge


34


, and the rear section


72


is sealably attached to the side panels


24


, and to the rear panel


38


along the back peripheral edge


36


. The rear section


72


is further rigidly attached to the handle assembly


112


by one or more screws, clamps, straps or other such means so that it retains a fixed position relative to the handle assembly


112


when the bag cap


70


is opened or closed. The bag cap


70


is further comprised of a releasable latch mechanism


74


to hold the front section


71


securely latched to the rear section


72


when the bag cap


70


is positioned in the closed position. The latch mechanism


74


is more fully described with reference to FIG.


8


. As shown therein, the latch mechanism


74


is comprised of a release plunger


74


coupled to a tapered pawl


75


that lachably engages a catch


78


that is located on the interior wall of the rear section


72


when the bag cap


70


is positioned in the closed position. The release plunger


74


and tapered pawl


75


are tensioned by a spring (not shown), or other resilient member that permits the pawl


75


to lachably engage the catch


78


when the front section


71


is moved to the closed position. The front section


71


is further comprised of a sealing surface


76


which adjoins a substantially overlapping sealing surface


77


located on the rear section


72


when the bag cap


70


is in the closed position.




Still referring to

FIG. 8

, the bag cap


70


is shown in the open position. As shown therein, releasing the releasable latch mechanism


74


and rotating the front section


71


downwardly conveniently allows access to the interior space


42


of the outer bag assembly


65


. The bag cap


70


thus advantageously permits the outer bag assembly


65


to be conveniently opened, enabling the user to more easily access the interior region


42


without flexing the side panels


24


. Correspondingly, the original shape and appearance of the outer bag is retained for a longer period of time.




The bag clip assembly


26


will now be more fully described with reference to FIG.


9


. The bag clip assembly


26


is comprised of a bag clip front member


80


and a bag clip rear member


81


that engage the bottom edges of the front panel


22


, the rear panel


38


, and the side panels


24


. The bag clip rear member


81


is secured to a bag clip spring


82


, which is, in turn, attached to the handle assembly


112


by a bag clip clamp


84


. Alternatively, the bag clip spring


82


may be attached to other structure capable of supporting the bag clip assembly


26


, such as a dirt suction tube (not shown). A fastener


86


attaches the bag clip clamp


84


to the bag clip spring


82


. The bag clip front member


80


and the bag clip rear member


81


are releasably attachable by a plurality of locking tabs


85


located on the bag clip rear member


81


that engage a plurality of locking recesses (not shown) on the bag clip front member


80


that lock the bag clip front member


80


and the bag clip rear member


81


together when the locking tabs


85


are mated with the locking recesses. Alternatively, the locking tabs


85


may be located on the bag clip front member


80


, and mate with locking recesses located on the bag clip rear member


81


. Other means for attaching the bag clip front member


80


and the bag clip rear member


81


include resiliently joining the members by “snapping” the members together, or by joining with adhesives, or by any other conventional fastening means such as screws.




With reference still to

FIG. 9

, the bag clip front member


80


and the bag clip rear member


81


may be further comprised of a plurality of teeth


83


disposed on the outer bag gripping surfaces


87


and


88


. The teeth


83


advantageously provide additional compression between the bag clip front member


80


and the bag clip rear member


81


to further secure the lower end of the outer bag assembly within the bag clip assembly


26


. As an alternative, the teeth


83


may also project through pre-formed holes in the lower end of the outer bag assembly to further secure the outer bag assembly to the bag clip assembly


26


.





FIG. 10

depicts an isometric view of a bag clip spring according to an embodiment of the invention. The bag clip spring


82


comprises a retaining portion


90


that is coupled to a body portion


98


by a coupling portion


92


. The body portion


98


has an aperture


94


extending therethrough, and a pair of flexible portions


95


disposed on the opposite sides of the aperture


94


. A mounting hole


96


extends through the body portion


98


to receive a bolt or other securing member to attach the bag clip spring


82


to the bag clip clamp


84


(as shown in FIG.


9


). The bag clip spring


82


may be fabricated from any suitable material, but preferably is fabricated from a durable, resilient thermoplastic material. Examples of suitable resilient materials include nylon materials, but preferably, the bag clip spring


82


is fabricated from a thermoplastic elastomer such as SANTOPRENE®, or a synthetic rubber. Alternatively, the bag spring clip


82


may be fabricated from a polypropylene material.





FIG. 11

is a partial cross-sectional top plan view of the bag spring clip


82


engaged with the bag clip rear member


81


. As shown therein, the bag clip rear member


81


has a mounting slot


88


disposed therein. The mounting slot


88


is dimensioned to receive the body portion


98


while still being sufficiently small to prohibit the passage of the retaining portion


90


therethrough. During assembly, the body portion


98


is slipped into the mounting slot


88


and the flexible portions


95


are correspondingly compressed inwardly toward the aperture


94


until the body portion


98


is passed completely through the mounting slot


88


. In the assembled position, the coupling portion


92


is positioned within the mounting slot


88


with the retaining portion


90


being engaged against the bag clip rear member


81


.





FIG. 12

is a partial cross-sectional top plan view of an alternate embodiment of a bag spring clip


100


engaged with the bag clip rear member


81


. In this embodiment, the bag spring clip


100


includes an approximately square-shaped body portion


102


having an aperture


104


disposed therethrough. Flexible portions


106


are disposed on opposite sides of the aperture


104


. The bag spring clip


100


is engaged with the bag clip rear member


81


as described above, with the body portion


102


being slipped through the mounting aperture


88


until the coupling portion


92


is disposed within the mounting aperture


88


and the retaining portion


90


is engaged with the bag clip rear member


81


.




The various embodiments of the bag spring clip previously described advantageously provide a durable and resilient means for attaching the bag clip assembly


26


to the handle assembly


112


. Because the bag spring clip is preferably fabricated from a durable, resilient thermoplastic material, it is not easily permanently deformed or broken in normal use. For example, the bag clip assembly


26


may frequently strike furniture when the vacuum cleaner is in normal use or during transport or storage of the machine. When an object impacts the bag clip assembly


26


, the bag spring clip elastically deforms to absorb the force of the blow, returning to its initial shape subsequent to the impact. Consequently, the outer bag assembly requires less repair and maintenance, and may experience longer life.





FIG. 13

depicts an isometric view of an outer bag assembly according to yet another alternate embodiment of the invention. The outer bag assembly


110


includes a front panel


22


, a pair of side panels


24


, and a top panel


28


that are fabricated from any suitable, air-permeable fabric material. The outer bag assembly


110


is further comprised of an abrasion-resistant front protective panel


120


positioned on a lower portion of the front panel


22


, and abrasion-resistant corner protective panels


122


positioned adjacent to the corners on an upper portion of the front panel


22


. Similarly, abrasion-resistant side protective panels


123


are positioned adjacent to the corner protective panels


122


that at least partially overlap the side panels


24


and the top panel


28


. The front protective panel


120


, corner protective panels


122


and side protective panels


123


are similarly comprised of any suitable, air permeable fabric material. Further, the front protective panel


120


, corner protective panels


122


and side protective panels


123


may be affixed to the surfaces of the outer bag assembly


110


by any suitable method. For example, the protective panels


120


,


122


and


123


may be stitched to the fabric of the outer bag assembly


110


. Alternatively, the protective panels


120


,


122


and


123


may be adhesively or thermally bonded to the fabric of the outer bag assembly


110


.





FIG. 14

shows an isometric view of an outer bag assembly according to still another embodiment of the invention. As shown therein, the outer bag assembly


130


includes a front panel


22


, a pair of side panels


24


, and a top panel


28


. The outer bag assembly


130


is further comprised of a single, unitary, abrasion-resistant front protective panel


140


that is positioned on the front panel


22


that substantially covers a lower portion of the front panel


22


and further extends upwardly along the front peripheral edge


34


to cover the upper corners of the front panel


22


. Abrasion-resistant side protective panels


123


are positioned on the outer bag assembly


130


to at least partially overlap the side panels


24


and the top panel


28


. The front protective panel


140


and the side protective panels


123


are similarly comprised of any suitable, air permeable fabric material. Moreover, the front protective panel


140


and the side protective panels


123


may be affixed to the surfaces of the outer bag assembly


130


by any suitable method. For example, the protective panels


140


and
