    Abstract: A washable cloth vacuum cleaner filter bag for use on wet/dry vacuum cleaners and in central vacuum cleaner systems includes a first opening for receiving vacuumed debris, means for attaching the first opening to the inlet of the vacuum cleaner or system, and a second opening, which is reversably sealable, for removing the vacuumed debris from the bag. In combination with the bag, the vacuum cleaner or system may be successfully used to suction up fine particulate debris, including gypsum dust and MDF dust. For a preferred embodiment of the new vacuum cleaner filter bag, the bag, which is of generally rectangular shape, is fabricated from a tight weave, synthetic-fiber cloth having a warp of about 160 threads per inch and a weft of about 68 threads per inch. A variety of fastener types may be employed for the reversably sealable second opening. The second opening incorporates a cuff on one side of the opening which is turned inside out to fold over the edge of the other side of the bag.

  • Patent number: 6749654
    Abstract: A dust collection system includes a housing defining an inlet and an outlet. A fan is situated within the housing to move air from the inlet to the outlet, and a filter is removably attached to the housing to collect dust entering the housing. To prevent dust from escaping the filter when it is removed from the housing for cleaning or disposal a cover is removably attached to the filter when it is desired to remove the filter. To insure the cover is available the next time it is necessary to remove the dust-laden filter, the cover may be attachable to the housing for storage thereon.

  • Patent number: 6733555
    Abstract: A user closable collar for a vacuum cleaner bag, the collar body being formed from a single blank of relatively rigid material which is folded to define three generally overlapping and planar panels, a middle panel having fixed raceway element which is adhesively secured to a first outer panel and a second outer panel, each of the outer panels having openings or apertures. A slider element is securely attached to the raceway element during the assembly process by retention bands of collar blank material and has containing an aperture thereon which is aligned with the apertures of the outer panels when in a closed position. The retention bands of collar material are cut through one of the outer panels, releasing the slider element such the slider element can be moved by a user from an open position to a closed position causing the apertures of said first and second outer panels to be occluded.

  • Patent number: 6626969
    Abstract: An apparatus for mounting a vacuum cleaner filter bag on a vacuum cleaner fill tube includes a filter bag panel. The panel is configured to be grasped by a hand to mount the bag on the fill tube. The panel has an inner edge defining an opening for receiving the fill tube when the bag is mounted on the fill tube. The panel further has an outer edge. A first recessed section of the outer edge is sized and shaped to receive a single finger of the hand when the hand grasps the panel. The first recessed section has a first innermost location. A second recessed section of the outer edge is sized and shaped to receive the thumb of the hand when the hand grasps the panel. The second recessed section has a second innermost location. The innermost locations are spaced apart from each other along an imaginary straight line extending across the opening.

  • Publication number: 20020166449
    Abstract: The present invention is an improved vacuum collection bag for vacuum cleaners and other appliances. By employing an impermeable bag and an air-permeable particle separator together with a tight seal against a vacuum system dirt tube in place of a conventional paper bag filter, it has been determined that the vacuum cleaner bag can be reused and significantly improve the filtration performance of the vacuum system.

  • Patent number: 6461394
    Abstract: A dust bag for vacuum cleaners including a bag shaped member of an air permeable material, adjacent to an inlet opening attachable by an adhering layer to a plate shaped member to facilitate mounting of the dust bag in an intended vacuum cleaner. The adhering layer is protected before use by a removable protective film. The adhering layer includes a number of parts joined with the bag shaped member surrounding an inlet opening, adjacently located and having an increasing distance in relation to each other from the inlet opening, each having an individual protective part of the removable protective film, preferably divided in separate segments by tear off indicates facilitating removal of individual parts of the protective film to adapt the area of resulting adhering layer to utilized plate shaped member, as well as adaption of the inlet opening by tearing off such segments together with underlying bag material.

  • Patent number: 6379408
    Abstract: A sealable debris bag includes a bag body having an opening, and a plate member attached to the bag body proximate the opening. First and second portions of the plate member are pivotable along a fold-line so that the first portion is engageable with the second portion to substantially seal the opening. A tab on one side of the fold-line engages a notch on the other side of the fold-line to secure the device. The fold-line can be formed in the plate member, to define the first and second portions where the portions are contiguous, or can be formed in the bag body where the portions are non-contiguous. The opening may be formed in a flexible lateral wall of the bag body, or alternately, in an end portion of the bag body. A complimentary alignment structure on plate member mates with an alignment structure on a vacuum to ensure proper alignment of the debris bag on the vacuum.

  • Patent number: 6224645
    Abstract: A dust separator for a vacuum cleaner, in which the bag is sealingly connected to a rigid member that screens-off an air-flow passageway through the vacuum cleaner and has an opening with which the bag connects. The screening member is separate from the bag. Mounted at the orifice of the bag is a flange which functions to prevent the bag from being drawn through the opening in the screening member in the direction of air flow through the vacuum cleaner. The flange can be collapsed to enable it to be passed through the opening in the screening member when the bag is full.

  • Patent number: 6178592
    Abstract: A lightweight ballast frame with a metal rim spanned by one or more metal mullions is loosely anchored at several points to a flexible screen mesh covering a vent formed in an enclosure defining a collection chamber and providing an escape portal for the exhaust airstream which has deposited entrained debris in the chamber. The ballast frame resists outward ballooning of the flexible screen caused by the airstream, and promotes scavenging of debris adhering to the interior of the flexible screen.

  • Patent number: 6136056
    Abstract: A connection member for a filter bag for vacuum cleaning equipment. The member has a base with two superposed base layers of stiff material which together define a first passage opening. A slide element, located between the two layers of the base, has a second passage opening therein which in an initial position is aligned with the first passage opening. By pulling on a handle portion of the slide element, the first passage opening is closed by a closure element that is connected to the slide element. The closure element, in the initial position, is in the form of a strand of incompletely cured plastic material. Upon application of a tensile force, the strand is adapted to plastically deform. The plastic material furthermore adheres on the one side to the slide element and on an opposed side to the base. Upon movement of the slide element into the closed position, the material is adapted to stretch in the longitudinal direction and to be drawn out as a diaphragm closing the first passage opening.
