DETAILED DESCRIPTION OF THE INVENTION

[0020] With reference now to the drawings, and in particular to FIGS. 1 through 8 thereof, a new wall sanding device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.

[0021] As best illustrated in FIGS. 1 through 8, the wall sanding apparatus 10 generally comprises a plate 12 having a top side 14, a bottom side 16, a front edge 18, a rear edge 20, a first lateral edge 22 and a second lateral edge 24. The top side 14 may have any useful size but typically will have a length and width each being between 3.0 inches and 18.0 inches. The top side 14 is typically planar though its shape is not germane to its function and therefore the term “planar” when used herein as referencing the plate 12 may refer to the top side 14 or a plane that extends through and is continuous with a peripheral edge of the plate 12.

[0022] A handle 26 is engaged to the top side 14. In one embodiment, the handle 26 includes a connector 28 pivotally coupled to the top side 14 and a grip 30 is removably attached to the connector 28. The connector 28, as can be seen in FIG. 3, may be pivotable about two axis. The grip 30 shown in FIG. 8 includes an elongated pole. The grip 30 and connector 28 may include a threaded connection as is often utilized with work tools which include an elongated pole. It should be understood that different types of handles 26, such as those that extend no more than a few inches from the plate 12 and are to be used with a single hand to form a handhold for the user may also be utilized.

[0023] An abrasive element 32 configured to sand joint compound positioned on a wall 34 has an upper surface 36 that is removably attached to the bottom side 16 and has lower surface 38 comprising an abrasive surface facing away from the bottom side 16. The abrasive element substantially covers the bottom side 16 and the abrasive element 32 comprises a resiliently compressible material. Such sanding materials are conventional and typically include a foamed elastomeric material coated in an abrasive of granular material wherein the particles of the granular material are sized depending on the needs of the person performing the sanding task.

[0024] A coupler 40 releasably couples the abrasive element 32 to the bottom side 16. The coupler 40 includes a first mating member 42 attached to the abrasive element 32 and a second mating member 42 attached to the bottom side 16. The first 42 and second 44 mating members are releasably engaged with each other. In some embodiments, as shown in the Figures, the first and second mating members comprise hook and loop mating members. Alternative attachment means may include snaps, magnets, releasable adhesives and the like.

[0025] The abrasive element 32 has a forward edge 46 and a rearward edge 48 corresponding, respectively, to the front edge 18 and that rear edge 20 when the abrasive element 32 is positioned on the plate 12. The forward edge 46 is adjacent to the front edge 18 and is angled outwardly away and downwardly from the plate 12 such that the forward edge 46 extends forwardly of the front edge 18. An acute angle formed at a juncture of the forward edge 46 and the lower surface 38 is less than 75°, and typically no greater than 60°, to define an angled edge 50. This allows the abrasive element 32 to better engage and sand adjacent to interior corners 52, i.e. corners of less than 180° such as where a ceiling meets a wall and where where two wall surfaces meet. The angled edge 50 will also allow for sanding the corners 52 as well. Typically, the forward edge 46 also includes the abrasive surface.

[0026] The rearward edge 48 extends rearwardly beyond the rear edge 20 of the plate 12 wherein a distance from the rearward edge 48 to the angled edge 50 is greater than a distance from the front edge 18 to the rear edge 20. This ensures that while a person is using the system 10, the front 18 and rear 20 edges of the plate 12 will not abut and mar an adjacent wall surface 54, that is perpendicular to the wall 34 being sanded, since the abrasive element 32 will first contact the adjacent wall surface 54 before the adjacent wall surface 54 will contact the abrasive element 32.

[0027] A flange 56 is attached to and extends upwardly from the upper surface 36 and the rearward edge 48. The flange 56 abuts the rear edge 20 of the of the plate 12. The flange 56 is co-extensive with the rearward edge 48 and has an outer surface 58 that is co-planar with the rearward edge 48. The outer surface 58 includes the abrasive surface and allows for sanding the adjacent wall surface 54, particularly when used in a corner 52 of two walls. The flange 56 forms a unitary structure with the abrasive element 32.

[0028] A pair of rollers 60 is rotatable mounted to the top side 14 of the plate 12. The rollers 60 each have an axis of rotation orientated perpendicular to a plane of the top side 14. More particularly, each of the rollers 60 has a perimeter edge 62 wherein the perimeter edges 62 of the rollers 60 extend further forward of the plate 12, relative to the rear edge 20, than a juncture of the bottom side 16 and the front edge 18 such that the perimeter edges 62 of the rollers 60 prevent abutment of the front edge 18 with a wall orientated perpendicular to the plane of the top side 14. As can be seen in FIG. 7, the perimeter edge 62 may extend beyond the angled edge 50, however, this positioning is not required since the angled edge 50 may extend further outwardly, relative to the rear edge 20, than the perimeter edge 62. Essentially, the purpose of the rollers 60 is to prevent marring of a wall surface caused by the front edge 18 being rubbed against the wall surface.

[0029] A biasing member 64 is attached to the bottom side 16 and extends along the front edge 20. The biasing member 64 matches a contour of the forward edge 46 and abuts the forward edge 46 of the abrasive element 32. The biasing member 64 extends from a juncture of the upper surface 36 toward the angled edge 50 and is spaced from the angled edge 50. The biasing member 64 most typically forms a unitary structure with the plate 12. Because the biasing member 64 matches the contour of the forward edge 46, it includes an elongated edge 66, forming an angle of less than 75° and more typically no greater than 60°, that downwardly extends and is coextensive with the forward edge 46 when the abrasive member 32 is mounted on the plate 12. The elongated edge 66 prevents the forward edge 46 from buckling when the angled edge 50 is positioned in a corner 52 of two adjoining walls 34, 54. Thus, the abrasive member 32 retains a “pointed edge” for sanding the corner 52 itself.

[0030] In use, the abrasive element 32 is selected for its abrasive properties and attached to the plate 12 as described above and shown in the Figures. The abrasive element 32 is then used to sand areas of sheet rock, after installation to form a wall, where the wall is not smooth due to joints, fasteners and the like which have been covered by joint compound. The angled edge 50 allows a user to easily sand up to and within corners 52 while the rollers 60 prevent marring of walls which might otherwise occur due to the plate 12 being rubbed against the walls during the sanding process.

[0031] With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.

[0032] Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
