One embodiment includes a tortuous air flow path created by baffles that divert air flow. The tortuous path creates quieter air flow through the vacuum housing. The tortuous air flow arrangement is for cooling the internal parts of a vacuum cleaner. Another embodiment includes an indicator light assembly for the vacuum cleaner visually providing the user with the vacuum's current operation status. In another embodiment, the rear wheels are recessed within the head housing and slightly offset rearwardly of the rear wall of the head housing to provide enhanced maneuverability.Type: GrantFiled: November 21, 2001Date of Patent: December 24, 2002Assignee: Oreck Holdings, LLCInventors: Chris M.

Publication number: 20020066154Abstract: The invention relates to a vacuum cleaner nozzle with a top part of the housing and a bottom plate. The bottom plate has a suction mouth that is realized in the form of a channel extending transversely in relation to the direction of movement. Thread lifting strips made of textile material are arranged on both sides of the suction mouth in recesses in the bottom plate. According to the invention, the ratio of the nozzle width (B) measured at the ends of the suction mouth, to the length (L) of the thread lifting strips is lower than 2.8.Type: ApplicationFiled: December 6, 2000Publication date: June 6, 2002Inventors: Dieter Kaffenberger, Hans-Joachim Steudtner

Patent number: 6370731Abstract: A dusting attachment device is disclosed for use in interaction with a line or connection hose of a suction or blowing type cleaning system. The invention is provided with a core unit with base and apex ends and three lengthwise oriented portions. The core has a cone, truncated cone, pyramid or truncated pyramid shape, in preferred embodiments. The invention's core is provided with a selected functional patterning of air apertures which extend through the core's outboard and inboard surfacing and communicate with the core's central air channel. As patterned, each of the air apertures have an interstitial space portion between each other, which sets forth air apertures and interstitial spaces on the outboard and inboard surfaces of the core's apex end and first two portions. The apertures are also arranged in sequence and position in relation to one another.Type: GrantFiled: January 17, 2000Date of Patent: April 16, 2002Inventor: William B. Carter

Publication number: 20020038490Abstract: A low-profile and highly-maneuverable vacuum cleaner having improved functionality including, alone or in combination, a headlight, a sidelight, anti-ingestion bars, side brushes, a squeegee, and a scent cartridge for use in cleaning floors, floor coverings, carpets, upholstery, and other surfaces. One embodiment includes a tortuous air flow path created by baffles that divert air flow. The tortuous path creates quieter air flow through the vacuum housing. The tortuous air flow arrangement is for cooling the internal parts of a vacuum cleaner. Another embodiment includes an indicator light assembly for the vacuum cleaner visually providing the user with the vacuum's current operation status. In another embodiment, the rear wheels are recessed within the head housing and slightly offset rearwardly of the rear wall of the head housing to provide enhanced maneuverability.Type: ApplicationFiled: November 21, 2001Publication date: April 4, 2002Inventors: Chris M.

Publication number: 20020020036Abstract: A multi-use floor tool, with which the same nozzle can be used in both dry and wet vacuum operation, and which allows for both wet and dry cleaning attachments to be easily attached and removed is disclosed. One such cleaning attachment for dry operation is a bristle brush which, when attached to the nozzle, is able to rotate, such that debris is collected with both the push and pull cleaning motions and such that for each motion, air flows primarily through the side of the nozzle at which debris is being gathered. The attachment for wet operation is a squeegee, which is rigidly attached to the nozzle having an insert which reduces the area of air flow into the nozzle and thereby increases the effectiveness of wet cleaning. This design increases the effectiveness of both wet and dry operation, and allows the operator to effectively clean in both wet and dry conditions while using the same nozzle.Type: ApplicationFiled: April 25, 2001Publication date: February 21, 2002Applicant: EMERSON ELECTRIC COMPANYInventors: Michael F.

Patent number: 6330732Abstract: The present invention provides a dust collect device for an eraser. It is related to a box, which has an inside box to separate the inside of the box into an inner space and an outer space. An inhaler component is set in the inside box, and it connects the inner space with the outer space. A dust bag, which is ventilated, is placed in the inner space, and it connects a dust guide pipework with the eraser to form a connective structure, so that users can operate the inhaler component at any time to absorb the dust into the dust bag. Thus, the dust is collected instead of floating and spreading in the air, so the environment can stay clean.Type: GrantFiled: July 19, 2000Date of Patent: December 18, 2001Inventor: Te-Hsi Liu
