Thedrum 28 is coupled to each of the plurality ofsupports 16. Thedrum 28 comprises aninterior layer 32 bonded to anexterior layer 34. Theinterior layer 32 is rigid, while theexterior layer 34 is pliant. Theexterior layer 34 comprises sponge, preferably rubber sponge. - A
channel 36 extends from proximate to thesecond end 22 of theshaft 12 to proximate to thesupports 16. Apivot hole 38 bisects thechannel 36 proximate to thesecond end 22 of theshaft 12. Thepivot hole 38 is positioned in a pair ofopposing faces 40 of theshaft 12. Anarm 42 that is complimentary to thechannel 36 has apenetration 44 proximate to afirst terminus 46. Thepenetration 44 is complimentary to thepivot hole 38. Apivot pin 48 that is complimentary to thepivot hole 38 and thepenetration 44 in thearm 42 is positioned in thepivot hole 38 and thepenetration 44, such that thearm 42 is pivotally retained in alignment with thechannel 36. Awedge 50 is coupled to asecond terminus 52 of thearm 42. Thewedge 50 is complimentary to thelongitudinal gap 30. - The
attachment 10 may comprise a lock 53. The lock 53 is configured to secure thearm 42 in thechannel 36, such that thewedge 50 is secured in thelongitudinal gap 30. Arod 54, which is cylindrical, has afirst base 56 coupled to thesecond end 22 of theshaft 12. In one embodiment of the invention, the lock 53 comprises apin 58, astop 60 and asleeve 66. Thepin 58 is positioned in therod 54 proximate to thefirst base 56. Thepin 58 is spring loaded, such that the default position for thepin 58 is extending from therod 12. Thestop 60 is coupled to therod 54 proximate to asecond base 62 of therod 54. Thestop 60 comprises acircular extrusion 64 protruding from therod 54. Thesleeve 66 that is complimentary to therod 54 is positioned over therod 54. Ashank 68 is coupled to thesecond base 62 for coupling theattachment 10 to a rotary tool. - In a preferred embodiment of the invention, the lock 53 comprises a
bar 70 coupled proximate to thefirst terminus 46 of thearm 42 and extending perpendicularly from thearm 42. Thebar 70 comprises a plurality ofteeth 72 positioned to selectively couple to alatch 74 as thebar 70 is motivated through arecess 76 in therod 54. Thelatch 74 is spring loaded. Eachtooth 72 is positioned to couple to thelatch 74 such that thearm 42 is lockable with thewedge 50 secured in thelongitudinal gap 30. Arelease pin 78 is operationally coupled to thelatch 74, such that theteeth 72 are decouplable from thelatch 74. - In use, the
longitudinal gap 30 is positioned in thedrum 28 such that a polishing or sanding cloth or paper can be positioned by the user with the ends of the cloth or paper extending into thelongitudinal gap 30. Thewedge 50 is positioned on thearm 42 such that thewedge 50, when pivoted into thelongitudinal gap 30, will engage and retain the cloth or paper on thedrum 28. Thebar 70 is motivated through therecess 76 as thearm 42 is pivoted, such that theteeth 72 selectively couple to thelatch 74, thus retaining thearm 42 in thechannel 36 and thewedge 50 in thelongitudinal gap 30. Therein,attachment 10 is configured for coupling to a rotary tool using theshank 68. - 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.
- 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.
