Abstract:
A plate fastener for an electrostatic precipitator cell is provided according to an embodiment of the invention. The plate fastener includes a fastener shaft including a head. The fastener shaft extends through the electrostatic precipitator cell. The head is adapted to retain a first end plate of the electrostatic precipitator cell. The plate fastener further includes a plurality of spacers configured to fit onto the fastener shaft. A spacer of the plurality of spacers is adapted to be positioned between successive polarity plates of a plurality of plates of the electrostatic precipitator cell. The plate fastener further includes a one-way shaft retainer configured to affix to the fastener shaft. The one-way shaft retainer is adapted to retain a second end plate of the electrostatic precipitator cell. The plate fastener affixes the plurality of plates together into a set of spaced-apart plates.
Abstract:
An improved bag docking assembly for aligning a vacuum bag for engagement with a dirty air outlet nozzle on a vacuum cleaner, and for retaining the vacuum bag in the position of engagement. The assembly incorporates an anchor member and a mounting member. The anchor member serves to attach the bag docking assembly to the vacuum cleaner. The anchor member can be a substantially flat piece of plastic having a central opening for closely receiving the dirty air outlet nozzle on the vacuum cleaner. The central opening can have a shoulder for engaging a rim or similar protrusion formed about the perimeter of the dirty air outlet nozzle. Additionally, protrusions are located on the anchor member that align with voids in the vacuum bag collar to ensure that correct alignment of the vacuum bag has been achieved.
Abstract:
An electrostatic precipitator cell is provided according to an embodiment of the invention. The electrostatic precipitator cell includes a connection rod including first and second ends, a length, a cross-sectional shape, and a lengthwise surface. The electrostatic precipitator cell further includes collection plates located in spaced-apart arrangement on the connection rod. A collection plate includes at least one aperture. The central aperture substantially conforms to the cross-sectional shape of the connection rod. The electrostatic precipitator cell further includes an attachment device(s) for removably attaching the collection plates to the connection rod. The collection plates are held in a substantially parallel orientation on the connection rod by the attachment device(s).
Abstract:
A cord management system operable to reduce or eliminate various forces exerted on a vacuum cleaner power cord. The system includes a swiveling strain relief incorporated into the vacuum handle and collars, used to connect sections of dirty air conduit, having exterior portions that enable the power cord to be retained in a secure manner.
Abstract:
An air cleaner base assembly is provided according to an embodiment of the invention. The base assembly includes a base body including an at least partially hollow interior, one or more fastener apertures formed in the body and adapted to receive one or more corresponding base fasteners, one or more clearance depressions formed in the body, and an access port comprising an access hole and a plug that substantially seals the access hole.

Abstract:
A low-profile and highly-maneuverable vacuum cleaner having improved functionality including a belt storage compartment located in the bottom cover of the housing. The belt storage compartment is shaped so as to allow for storage of the belt in its relaxed state.
Abstract:
An airflow shaper for use in an air cleaner is provided according to an embodiment of the invention. The airflow shaper includes a body including a substantially central axis and a raised central region formed on the body. The raised central region transitions an impinging axial airflow into a substantially radial airflow or transitions an impinging radial airflow into a substantially axial airflow.
Abstract:
An ergonomic appliance handle is provided according to an embodiment of the invention. The appliance handle includes a base adapted to be affixed to a handle portion of an appliance, a handle grip, and a pivot device for pivotally attaching the handle grip to the base. The pivot device is positioned at a first location on the base. The pivot device allows the handle grip to pivot on the base between at least two pivoting positions. The appliance handle further includes a pivot restraint device for removably latching the handle grip in a closed position of the at least two pivoting positions. The pivot restraint device is positioned at a second location on the base that is spaced-apart from the first location.
