Abstract: Portable devices for mitigating the accumulation and localized settling of airborne particulates are provided. The devices establish airflow patterns which push or carry various airborne particulates outwardly away therefrom, thereby establishing a localized zone having relatively fewer airborne particulates. Correspondingly, each the devices establishes a localized zone, defined circumferentially about the perimeter of the device, in which there is relatively less surface accumulation of particulates which were previously airborne and settled out. The devices establish such airflow patterns by proving a fan which draws a volume of air axially through a top portion of the device, then pushes the volume of air axially down through the device where it is radially emitted from the bottom portion of the device, defining a circumferentially expanding plane of airflow.

Abstract: A device (20) for cleaning surfaces is provided utilizing a web (94) of a tackified sheet material movably secured between rollers (56, 58) on the device (20) that enable the web (94) to be moved over the surface in opposite directions. The device (20) includes a supply roller (56) and a take-up roller (58) secured to opposed ends of the web (94) of adhesive sheet material, with at least one roller (56, 58) including a biasing mechanism (82) disposed within the roller (56, 58). The web (94) can be engaged with the surface by passing over a number of idler rollers (98) positioned between the supply roller (56) and take-up roller (58). The biasing mechanism (82) is designed to bias the movement of the web (94) onto the take-up roller (58), such that the mechanism (82) can be selectively operated to advance the web (94) from the supply roller (56) to the take-up roller (58) to expose a clean section of the adhesive sheet material (94).

Abstract: A dusting device is disclosed. There is a telescoping handle, a shank mountable to the handle, and a supporting fork mounted to the shank for relative rotation with respect thereto. A cleaning sleeve is replaceably mountable on the fork for single use dusting purposes. The angle of the fork with respect to the telescoping handle can be releasably fixed by a catch mechanism. While the catch is sufficiently strong to resist angle adjustment during normal dusting, it permits the angle to be adjusted by firmly pressing the end of the fork (with or without the sleeve thereon) against a wall while holding the distal end of the telescoping handle. This converts the duster from a wall duster, to a duster capable of cleaning the tops of ceiling fan blades, without the need for a consumer to touch a portion of the device near the duster head. In another aspect the device has two such adjustable forks for holding two such sleeves which can be used simultaneously.
