  • Publication number: 20040158954
    Abstract: A novel vacuum attachment for vacuuming planar elements of varying widths is provided. The attachment comprises a hollow member having a first end adapted for attachment to a vacuum cleaner hose and a second end having one or more elongate apertures formed therein and adapted for receiving a planar element. Each elongate aperture comprising a pair of parallel arms having a hollow interior with opposing and facing openings, each opening being in communication with the elongate aperture and with the first end. The aperture is sufficiently long to accept a relatively wide planar element. The attachment further comprises adjustment means for selectively adjusting the effective length of the aperture which enables the attachment to accommodate planar elements of varying widths. In a preferred embodiment, the length adjustment means comprises a sliding member slidably positioned over the second end for selectively blocking a longitudinal portion of the aperture.

  • Patent number: 6345409
    Abstract: A vacuum nozzle attachment having a housing with a venturi-shaped internal air chamber, an angled head and brush-lined aperture, blade guides and an offset tapered tubular neck for attachment to a vacuum hose or wand. The constricted air chamber provides enhanced suction due to an increase in velocity of air as it passes the tapered constriction in the air chamber. The angled head and aperture and shaped guides ensure correct alignment of the fan blade with the aperture. The offset tubular neck and transparent guides provide an unobstructed view of the nozzle and fan blades during the cleaning process.
