Description
BACKGROUND OF THE DISCLOSURE
Field of the Disclosure
[0001] The disclosure relates to rotary tool attachments and more
particularly pertains to a new rotary tool attachment for sanding
and polishing.
SUMMARY OF THE DISCLOSURE
[0002] An embodiment of the disclosure meets the needs presented
above by generally comprising a shaft that is elongated and has a
plurality of longitudinal faces. A plurality of supports is coupled
to and extends outwardly from the shaft. The plurality of supports
comprises a pair of closely spaced supports. A drum is coupled to
and extends from one of the pair of closely spaced supports to the
other of the pair of closely spaced supports, such that a
longitudinal gap in the drum is defined by the pair of closely
spaced supports. The attachment includes an arm, which is
complimentary to a channel that extends from proximate to a second
end of the shaft to proximate to the supports, secured via a pivot
hole in the shaft and a pivot pin. A wedge, complimentary to the
longitudinal gap, is coupled to a second terminus of the arm.

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0012] With reference now to the drawings, and in particular to
FIGS. 1 through 5 thereof, a new rotary tool attachment embodying
the principles and concepts of an embodiment of the disclosure and
generally designated by the reference numeral 10 will be
described.
[0013] As best illustrated in FIGS. 1 through 5, the rotary tool
sanding and polishing attachment 10 generally comprises a shaft 12
that is elongated with a plurality of longitudinal faces 14. The
plurality of longitudinal faces 14 comprises six faces, such that
the shaft 12 is complimentary to the chucks utilized on rotary
tools. Each of a plurality of supports 16 is coupled to and extends
outwardly from the shaft 12. The plurality of supports 16 comprises
a pair of closely spaced supports 18. Each of the supports 16
extends from a first end 20 of the shaft 12 toward a second end 22
of the shaft 12. The plurality of supports 16 comprises a pair of
supports 24 positioned at 180 degrees on the shaft 12, a third
support 26 bisecting the pair of supports 24, and the pair of
closely spaced supports 18 positioned approximately opposite the
third support 26.
[0014] A drum 28 is coupled to and extends from one of the pair of
closely spaced supports 18 to the other of the pair of closely
spaced supports 18, such that a longitudinal gap 30 in the drum 28
is defined by the pair of closely spaced supports 18. The drum 28
is coupled to each of the plurality of supports 16. The drum 28
comprises an interior layer 32 bonded to an exterior layer 34. The
interior layer 32 is rigid, while the exterior layer 34 is pliant.
The exterior layer 34 comprises sponge, preferably rubber
sponge.
[0015] A channel 36 extends from proximate to the second end 22 of
the shaft 12 to proximate to the supports 16. A pivot hole 38
bisects the channel 36 proximate to the second end 22 of the shaft
12. The pivot hole 38 is positioned in a pair of opposing faces 40
of the shaft 12. An arm 42 that is complimentary to the channel 36
has a penetration 44 proximate to a first terminus 46. The
penetration 44 is complimentary to the pivot hole 38. A pivot pin
48 that is complimentary to the pivot hole 38 and the penetration
44 in the arm 42 is positioned in the pivot hole 38 and the
penetration 44, such that the arm 42 is pivotally retained in
alignment with the channel 36. A wedge 50 is coupled to a second
terminus 52 of the arm 42. The wedge 50 is complimentary to the
longitudinal gap 30.
[0016] The attachment 10 may comprise a lock 53. The lock 53 is
configured to secure the arm 42 in the channel 36, such that the
wedge 50 is secured in the longitudinal gap 30. A rod 54, which is
cylindrical, has a first base 56 coupled to the second end 22 of
the shaft 12. In one embodiment of the invention, the lock 53
comprises a pin 58, a stop 60 and a sleeve 66. The pin 58 is
positioned in the rod 54 proximate to the first base 56. The pin 58
is spring loaded, such that the default position for the pin 58 is
extending from the rod 12. The stop 60 is coupled to the rod 54
proximate to a second base 62 of the rod 54. The stop 60 comprises
a circular extrusion 64 protruding from the rod 54. The sleeve 66
that is complimentary to the rod 54 is positioned over the rod 54.
A shank 68 is coupled to the second base 62 for coupling the
attachment 10 to a rotary tool.
[0017] In a preferred embodiment of the invention, the lock 53
comprises a bar 70 coupled proximate to the first terminus 46 of
the arm 42 and extending perpendicularly from the arm 42. The bar
70 comprises a plurality of teeth 72 positioned to selectively
couple to a latch 74 as the bar 70 is motivated through a recess 76
in the rod 54. The latch 74 is spring loaded. Each tooth 72 is
positioned to couple to the latch 74 such that the arm 42 is
lockable with the wedge 50 secured in the longitudinal gap 30. A
release pin 78 is operationally coupled to the latch 74, such that
the teeth 72 are decouplable from the latch 74.
[0018] In use, the longitudinal gap 30 is positioned in the drum 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 the
longitudinal gap 30. The wedge 50 is positioned on the arm 42 such
that the wedge 50, when pivoted into the longitudinal gap 30, will
engage and retain the cloth or paper on the drum 28. The bar 70 is
motivated through the recess 76 as the arm 42 is pivoted, such that
the teeth 72 selectively couple to the latch 74, thus retaining the
arm 42 in the channel 36 and the wedge 50 in the longitudinal gap
30. Therein, attachment 10 is configured for coupling to a rotary
tool using the shank 68.
[0019] 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.
[0020] 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.
