Multi-layer bag assembly includes at least two bags arranged one inside the other. Each of the bags includes an air permeable filtering material for collecting particles carried by air flowing through the material. The air permeable filtering material being may be the same or different for the at least two bags. The multi-layer bag assembly includes structure for holding the at least two bags in a wide open position. The structure may be a cooperating bag structure incorporated in the at least two bags for cooperating with the housing for selectively holding the respective bags in their respective open conditions. The structure may also be a removable collar attached to at the open portion of the at least two bags, where the removable collar is part of an integral collar of the multi-layer bag assembly.

Abstract: A filter bag arrangement for a vacuum cleaner includes a bag body of filter material, and a stiffening element in the form of a filter mounting plate with an inlet opening of the bag therein. The vacuum cleaner includes a housing defining a chamber into which the bag may be inserted, a lid to cover the chamber, and a filling pipe stub that is insertable into the inlet opening. Plural individual mounting elements are provided at the outer edge of the stiffening element and are inserted into corresponding individual receivers of the housing so as to spatially position and fix the inlet opening of the filter bag arrangement relative to the housing of the vacuum cleaner.

Abstract: A removable dust collector for use in a dust compartment of a vacuum cleaner is provided and includes a holder that maintains the dust collector in an operating position, and a locking member that is placed in a locking position when the dust collector is removed. A cover of the dust compartment is prevented from closing and is placed in a release position when the dust collector is in an operating position. The locking member is maintained in its release position either by means of a filter bag inserted into a carrier or by an actuating member associated with the dust collector.

Abstract: An upright vacuum cleaner having a separable handle for compact shipping is disclosed. The separable handle includes a lower handle portion pivotally attached to a floor engaging unit and is joined to an upper handle portion at a parting plane. A dust bag cover is mounted to the lower handle portion by a mounting device. The mounting device comprises a baseplate comprises a mounting plate mounted on an exhaust duct of the cleaner extending from the lower handle portion and a dust bag cover support frame attached to the baseplate. All portions of the frame are located below the frame for shipping purposes. According to one aspect of the invention the support frame extends at right angles to the base plate and, according to another aspect of the invention, the frame is extendable above the parting plane to a use position.

Abstract: The present invention is directed towards a vacuum cleaner bag cover which provides an enlarged access opening into the interior thereof. The vacuum cleaner bag, which is designed to enclose a removable dirt filtering and collecting bag, includes a main section and a front panel section. In a first embodiment, the front panel section is connected to the main section by a pair of parallel, vertically oriented zippers and a top member which snap-fits over the top of the main section. In a second embodiment, the front panel section is permanently attached to the main section along one edge, and releasably attached at an opposite edge by a vertically-oriented zipper. An interior frame is provided to vertically support the vacuum cleaner bag cover. In the first embodiment, access to the interior of the vacuum cleaner bag cover is gained by sliding the zippers downwardly, pulling the bag cover top member off the vacuum cleaner bag cover and folding the front panel section downwardly.

Abstract: An upright vacuum cleaner having a filter bag housing assembly comprised of a fabric or otherwise flexible and air permeable bag housing resiliently supported at its bottom end relative to the operator handle such that the bag housing is always in tension and is prevented from twisting about the axis of the operator handle. The bag housing assembly includes rigid upper and lower frame members thereby maintaining the assembly in a prescribed geometric shape. The lower frame member which defines the bottom of the bag housing includes a pair of laterally disposed elongated track members telescopically disposed within respective guide track members fixed to the handle and resiliently biased relative to the respective guide track member to thereby maintain the bag housing in tension and provide lateral stability to the bag housing at the same time.

Abstract: A permanent mounting assembly for a vacuum cleaner filter bag includes a plastic collar stitched to the porous body of the vacuum cleaner bag around the inlet opening thereof. The bag is mounted on the exterior surface of a projection on the vacuum cleaner housing. The exterior surface of the projection is provided with an annular groove. An interior rib on the collar is positioned within the groove to mechanically lock the bag on the projection of the housing. A nonelastic tie strap is positioned around the rib to permanently secure the rib in place and to provide a permanent fluidtight connection between the collar and the projection on the housing. The collar is provided with a band which is folded back to conceal the stitching, providing an attractive, neat appearance.

Abstract: A vacuum cleaner has an elongated porous outer bag for holding a filter bag over an air outlet. A hanger within the outer bag is positioned to suspend the outer bag from the vacuum cleaner, as well as to hold a pocket within the outer bag, so that spare filter bags may be held within the porous outer bag and an end flap extending into the outer bag.

Abstract: A filter bag construction for filtering dirt, dust and other materials from the exhaust air flow of an upright vacuum cleaner, wherein an elongated, non-disposable outer fabric bag having a longitudinally extending delivery tube therein provides one stage of filtration and a disposable, inner paper filter bag provides a second stage of filtration. The filter bag construction may be used without the inner, paper filter bag when maximum filtration efficiency is not required or with the inner, paper filter bag when high filtration efficiency and/or the convenience of a disposable filter element is desired. When operating as a single stage filter, the upper end of a flow channeling conduit in the lower end of the outer bag is positioned in the lower end of the delivery tube and, when operating as a two-stage filter, the upper end of the conduit is shifted to another position in the outer bag so that unfiltered air from the cleaner is initially channeled into the inner filter bag.

Abstract: A filter bag assembly for a vacuum cleaner is disclosed. The assembly includes an elongated, relatively rigid, hollow tube coupled at one end to the exhaust of a vacuum cleaner. The tube runs upwardly along the handle of the vacuum cleaner and is attached at its other end to a porous filter bag. The filter bag runs downwardly along the rigid tube and has an open end closed by a nonporous dirt-collecting bag. The tube, the porous bag, and the nonporous bag are encased in an envelope so that the nonporous bag is held in a collapsed or stored condition at the end of the filter bag during normal use of the cleaner. To empty the filter bag of its collected dirt, the envelope is opened to expose the nonporous bag and to permit the dirt in the filter bag to drop downwardly into the nonporous bag. The vacuum cleaner may be turned on and off a number of times to distend the bag and dislodge dirt from the filter bag during the emptying operation.

Abstract: A vacuum cleaner filter bag for an upright vacuum cleaner comprising an air pervious filter receptacle and an air impervious feed tube interconnected together so that the interior of the filter receptacle is in air-flowing relationship with the interior of the feed tube, where the feed tube is adapted to be connected to the vacuum cleaner. A collar is intermediately disposed within the filter receptacle and secured therein by a clamping ring disposed externally of the filter receptacle in juxtaposition with an upper portion of the collar. An air impervious dust receptacle is removably disposed within a lower portion of the filter receptacle with a mouth portion of the dust receptacle being disposed about a lower end of the collar. A resiliently expandable ring releasably secures the dust receptacle mouth portion about the collar so that the dust receptacle is maintained in an open mouth suspended condition within the filter receptacle to receive and collect debris introduced into the filter receptacle.
