Rather, the invention is capable of other embodiments and being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein are for purposes of description only and should not be regarded as limiting.

DETAILED DESCRIPTION OF POTENTIALLY PREFERRED EMBODIMENTS

(7) An exemplary embodiment consistent with the present disclosure will now be described in reference to the drawings wherein like elements are designated by like reference numerals in the various views. Referring now to the drawings, a manual dusting tool 10 consistent with the present disclosure is illustrated. As shown, the manual dusting tool 10 includes a handle 12 and an elongated paddle member 14 projecting outwardly away from the handle. In the illustrated exemplary construction, the paddle member 14 is rotatable relative to the handle about a pivot 16. In this regard, an adjustment mechanism such as thumbwheel, wingnut, or the like (not shown) may be used to loosen the connection between the handle 12 and paddle member 14 to permit relative rotation. Once a desired orientation is achieved, the adjustment mechanism can then be re-tightened to hold the handle 12 and paddle member 14 in that orientation.

(8) In accordance with one exemplary construction, the paddle member 14 may be formed from rubber of flexible plastic such as silicone rubber, NBR, SBR, LDPE, EPDM or the like. The rubber or flexible plastic forming the paddle member preferably has a Shore A hardness in the range of about 50-80 A and more preferably about 60-70 A although harder or softer materials may likewise be used if desired. The rubber or flexible plastic may be molded over and substantially centrally oriented around an elongated malleable spine 20 such as a rod or flat plate using techniques such as injection molding or the like. By way of example only, and not limitation, suitable materials for the spine 20 may be metals such as austenitic stainless-steel alloys and the like that can be readily bent to different shapes by a user without undergoing bulk strain hardening. Exemplary suitable alloys may include stainless grades 304, 304L, 316, 316L and other similar corrosion resistant ferrous alloys. The paddle member 14 can thereby be repeatedly bent to various angles of 0-360 degrees or more to form curves, circles and the like as may be desired. Of course, other malleable spine materials and over-molded coverings may likewise be used if desired.

(9) The paddle member 14 may also be bent in opposing directions along its length to adopt a serpentine shape if desired. As will be appreciated, the ability to bend the spine 20 away from its normal flat plane in two opposing directions permits the paddle member 14 to reversibly adopt and retain configurations such as curves and serpentine patterns which can then be maintained during use. In this regard, it will be understood that following bending, the spine 20 can then be re-flattened such that the paddle member is returned to its initial state if desired. The combination of bending and rotation relative to the handle 12 provides a user with the ability to adjust the device as necessary to clean a large variety of surfaces.

(10) In one exemplary construction, two opposing soft panels of rubber or flexible plastic cover the spine 20 in a sandwiched relation. The soft panels are fused or adhesively joined to one another or otherwise connected at zones outboard from the spine such that the spine 20 is entirely encapsulated. As illustrated, one or both soft panels covering the spine may be molded to incorporate a plurality of integral, raised flexible fins 22 oriented generally transverse to the length dimension of the paddle member 14 in a ladder rung orientation.

(11) As best seen in FIGS. 2 and 4, the flexible fins 22 provide a resilient underlying support structure for a replaceable and launderable sock-shaped cleaning element 24 of fibrous textile material or the like. In this regard, the cleaning element may have any number of constructions, but is preferably a tube enclosed on three sides to define a single channel at the interior to matedly receive the paddle member 14 in sliding relation. The flexible fins 22 act to hold the cleaning element 24 in an expanded condition surrounding the paddle member thereby simulating a high-loft textile structure. During use, flexible fins 22 may flex up and down at different locations as force is applied during the cleaning operation. This dynamic movement of localized fins 22 beneath the cleaning element 24 further facilitates cleaning efficiency by permitting the cleaning element to continuously adjust and conform more precisely with the surface being cleaned in real time during use.

(12) As shown, in the illustrated exemplary construction, the flexible fins 22 are molded to project rearwardly towards the handle 12 at an angle. In this regard, the flexible fins will preferably lean towards the handle to form an acute angle relative to the surface of the supporting panel in the range of about 35 to 85 degrees, and more preferably about 50 to 85 degrees. However, larger and smaller angles may be used if desired. As will be understood, this orientation for the fins 22 facilitates insertion of the paddle member 14 into the sock-shaped cleaning element 24 (FIGS. 2 and 4) of fibrous textile material or the like by permitting the fins to bend downwardly thereby decreasing the acute angle. The rearwardly angled orientation for the fins 22 also assists in blocking any unintended extraction of the paddle member 14 from the cleaning element 24 during use by forcing the fins to bend away from their molded orientation and away from the handle as the cleaning element is removed. Thus, in the absences of an intended applied removal force, the cleaning element 24 will remain in place.

(13) As best seen in FIG. 3, the handle 12 also preferably includes a receiving opening 30 at its proximal end. During use, this receiving opening 30 may engage an elongated extension pole (not shown) to extend a user's reach in a manner as will be well understood by those of skill in the art. However, the use of such an extension pole is in no way essential.

(14) The ability to contour the paddle member 14 to multiple different shapes while also adjusting the relative angle of the paddle member and securely holding the sock-shaped cleaning element 24 in place during use provides substantial advantages over existing hand-held dusting tools. In particular, a dusting tool 10 consistent with the present disclosure is far more adaptable to reach contoured surfaces in difficult-to-access locations. By way of example only, and not limitation, FIG. 4 illustrates the dusting tool 10 bent in a curved orientation such that a distal portion of the tool may be used to clean an elevated horizontal surface such as the top of an air duct or cabinet while the proximal portion may be used to simultaneously clean a vertical side surface. Such a curved surface may also be beneficial in cleaning elevated curved surfaces such as overhead piping which may be present in many industrial settings.

(15) Of course, it is to be understood that variations and modifications of the foregoing are within the scope of the present invention. Thus, it is to be understood that the invention disclosed and defined herein extends to all alternative combinations of two or more of the individual features mentioned or evident from the text and/or drawings. All of these different combinations constitute various alternative aspects of the present invention. The embodiments described herein explain the best modes known for practicing the invention and will enable others skilled in the art to utilize the invention.

(16) Preferred embodiments of this disclosure are described herein, including the best mode known to the inventors for carrying out the disclosure. Variations of those preferred embodiments may become apparent to those of ordinary skill in the art upon reading the foregoing description. The inventors expect skilled artisans to employ such variations as appropriate, and the inventors intend for the disclosure to be practiced otherwise than as specifically described herein. Accordingly, this disclosure includes all modifications and equivalents of the subject matter recited in the claims appended hereto as permitted by applicable law. Moreover, any combination of the above-described elements in all possible variations thereof is encompassed by the disclosure unless otherwise indicated herein or otherwise clearly contradicted by context.
