Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims priority to U.S. Provisional Patent
Application Ser. No. 62/587,238, filed on Nov. 16, 2017, and
entitled "LONG-LIFE ABRASIVE PAD," the entire disclosure of which
is incorporated herein by reference.
BACKGROUND
[0002] Sandpaper and other abrasive pads are generally known and
used in a variety of industries for removing material from surfaces
of various materials, e.g., wood, in order to smooth the surfaces,
roughen the surfaces, and/or prepare them for subsequent treatment
after one or more top layers of material are removed. These
products are consumable and generally have a short work life due to
the high degree of wear and tear caused during the abrasion
process. As such, these products rapidly deteriorate, which results
in a quickly diminishing service life and performance. Frequently
changing out worn out pads in order to maintain a sufficient level
of performance is generally a tedious and costly process.

[0003] The present disclosure is directed to a long-life abrasive
pad assembly.
[0004] According to an aspect is an abrasive pad assembly,
comprising: an abrasive layer having first and second surfaces with
the first surface being coated with material particles having
predetermined hardness characteristics; a substrate having first
and second surfaces with the first surface attached to the second
surface of the abrasive layer, the substrate being composed of a
material having stiff and resilient characteristics; and a
fastening layer having first and second surfaces with the first
surface being attached to the second surface of the substrate and
the first surface having fastening material disposed thereon.
[0005] According to an embodiment, the fastening material comprises
loop fabric.
[0006] According to an embodiment, the material articles are
composed of at least one of diamond, cubic boron nitride, aluminum
oxide, silicon carbide, and garnet.
[0007] According to an embodiment, the substrate is composed of any

DETAILED DESCRIPTION OF EMBODIMENTS
[0015] Referring to FIG. 1, in one embodiment, an abrasive pad 10
includes an abrasive surface 12. The abrasive surface 12 may be
formed from or include any material with a high hardness that is
capable of scratching or abrading other materials. Examples of
materials that can be used for the abrasive surface 12 include
diamond, cubic boron nitride, aluminum oxide, silicon carbide,
garnet, and other materials that have hardnesses similar to these
materials, e.g., according to the Mohrs, Vickers, or other hardness
scale. The abrasive surface 12 may comprise grit, chunks,
particles, flakes, shaving, chips, grains, or other fragments of
any of the aforementioned materials. The diameter or dimensions of
these fragments may range in size depending on the desired
smoothness desired to be achieved by the abrasive surface 12, i.e.,
with smoother finishes typically corresponding to smaller sized
fragments.
[0016] As shown in FIG. 2, the abrasive surface 12 of the abrasive
pad 10 is secured to a substrate 14, which is provided to provide
structurally integrity to the abrasive pad 10. For example, the
substrate 14 may take the form of a sheet or plate of durable and
generally stiff but resilient material, such as steel, brass,
aluminum, or other metals. In one embodiment, the abrasive surface
12 is made from a composite of the aforementioned abrasive material
and a bonding material to secure the abrasive material to the
substrate 14. The process to bond said abrasive to the substrate
may alternately and/or additionally include, but is not limited to,
electroplating, brazing, soldering, epoxy, or any other adhesive or
bonding processes known or discovered.
[0017] Opposite to the abrasive surface 12, the abrasive pad 10
includes a fastening surface 16 secured to the substrate 14 that
enables the abrasive pad 10 to be detachably secured to a handheld
abrading device. In one embodiment, the fastening surface 16
comprises a hook material or a loop material that corresponds to
complementary hook or loop material of an abrading device, e.g., a
handheld powered or unpowered device configured to receive and
attach to the abrasive pad 10.
[0018] In FIG. 3, a handheld device 18 is illustrated having a
fastening surface 20, which is complementarily formed with respect
to the fastening surface 16 such that the surfaces 16 and 20
together form a hook and loop type fastener or other detachable
attachment means 22. In this way, the abrasive pad 10 is capable of
detachably securing to a rotating, member 24 of the device 18. For
example, the device 18 may be an electrically or pneumatically
powered sanding tool having a handle 25 arranged to be held by a
user, a trigger 26 to be pulled to initiate movement of the member
24, and a motor 28 coupled to the member 24, e.g., via a shaft, to
provide the aforementioned movement in response to input from the
trigger 26. Advantageously, the attachment means 22 facilitates the
abrasive pad 10 to be quickly and easily changed, e.g., to a
variety of different abrasive grit sizes of the material of the
abrasive surface 12 for multiple different abrading procedures or
applications.
[0019] As another example, a handheld device 30 is illustrated in
FIG. 4. The handheld device 30 includes a main body 32 (e.g., which
may house a motor or other actuator or movement generator) to which
a vibrating or oscillating member 34 is attached. The member 34
includes a fastening surface 36 which may include hook and/or loop
material as described above with respect to the surfaces 16 and 20
and the attachment means 22 in order to detachably secure the
abrasive pad 10 thereto. Two of the abrasive pads 10, designated
with reference numerals 10a and 10b, are illustrated in FIG. 4.
More specifically, the fastening surface 16 of the abrasive pad 10a
and the abrasive surface 12 of the abrasive pad 10b are shown face
up, respectively, in FIG. 4.
[0020] While several inventive embodiments have been described and
illustrated herein, those of ordinary skill in the art will readily
envision a variety of other means and/or structures for performing
the function and/or obtaining the results and/or one or more of the
advantages described herein, and each of such variations and/or
modifications is deemed to be within the scope of the inventive
embodiments described herein. More generally, those skilled in the
art will readily appreciate that all parameters, dimensions,
materials, and configurations described herein are meant to be
exemplary and that the actual parameters, dimensions, materials,
and/or configurations will depend upon the specific application or
applications for which the inventive teachings is/are used. Those
skilled in the art will recognize, or be able to ascertain using no
more than routine experimentation, many equivalents to the specific
inventive embodiments described herein. It is, therefore, to be
understood that the foregoing embodiments are presented by way of
example only and that, within the scope of the appended claims and
equivalents thereto, inventive embodiments may be practiced
otherwise than as specifically described and claimed. Inventive
embodiments of the present disclosure are directed to each
individual feature, system, article, material, kit, and/or method
described herein. In addition, any combination of two or more such
features, systems, articles, materials, kits, and/or methods, if
such features, systems, articles, materials, kits, and/or methods
are not mutually inconsistent, is included within the inventive
scope of the present disclosure.
[0021] All definitions, as defined and used herein, should be
understood to control over dictionary definitions, definitions in
documents incorporated by reference, and/or ordinary meanings of
the defined terms.
[0022] The indefinite articles "a" and "an," as used herein in the
specification and in the claims, unless clearly indicated to the
contrary, should be understood to mean "at least one."
[0023] The phrase "and/or," as used herein in the specification and
in the claims, should be understood to mean "either or both" of the
elements so conjoined, i.e., elements that are conjunctively
present in some cases and disjunctively present in other cases.
Multiple elements listed with "and/or" should be construed in the
same fashion, i.e., "one or more" of the elements so conjoined.
Other elements may optionally be present other than the elements
specifically identified by the "and/or" clause, whether related or
unrelated to those elements specifically identified. Thus, as a
non-limiting example, a reference to "A and/or B", when used in
conjunction with open-ended language such as "comprising" can
refer, in one embodiment, to A only (optionally including elements
other than B); in another embodiment, to B only (optionally
including elements other than A); in yet another embodiment, to
both A and B (optionally including other elements); etc.
[0024] As used herein in the specification and in the claims, "or"
should be understood to have the same meaning as "and/or" as
defined above. For example, when separating items in a list, "or"
or "and/or" shall be interpreted as being inclusive, i.e., the
inclusion of at least one, but also including more than one, of a
number or list of elements, and, optionally, additional unlisted
items. Only terms clearly indicated to the contrary, such as "only
one of" or "exactly one of," or, when used in the claims,
"consisting of," will refer to the inclusion of exactly one element
of a number or list of elements. In general, the term "or" as used
herein shall only be interpreted as indicating exclusive
alternatives (i.e. "one or the other but not both") when preceded
by terms of exclusivity, such as "either," "one of" "only one of,"
or "exactly one of" "Consisting essentially of," when used in the
claims, shall have its ordinary meaning as used in the field of
patent law.
[0025] As used herein in the specification and in the claims, the
phrase "at least one," in reference to a list of one or more
elements, should be understood to mean at least one element
selected from any one or more of the elements in the list of
elements, but not necessarily including at least one of each and
every element specifically listed within the list of elements and
not excluding any combinations of elements in the list of elements.
This definition also allows that elements may optionally be present
other than the elements specifically identified within the list of
elements to which the phrase "at least one" refers, whether related
or unrelated to those elements specifically identified. Thus, as a
non-limiting example, "at least one of A and B" (or, equivalently,
"at least one of A or B," or, equivalently "at least one of A
and/or B") can refer, in one embodiment, to at least one,
optionally including more than one, A, with no B present (and
optionally including elements other than B); in another embodiment,
to at least one, optionally including more than one, B, with no A
present (and optionally including elements other than A); in yet
another embodiment, to at least one, optionally including more than
one, A, and at least one, optionally including more than one, B
(and optionally including other elements); etc.
[0026] It should also be understood that, unless clearly indicated
to the contrary, in any methods claimed herein that include more
than one step or act, the order of the steps or acts of the method
is not necessarily limited to the order in which the steps or acts
of the method are recited.
[0027] In the claims, as well as in the specification above, all
transitional phrases such as "comprising," "including," "carrying,"
"having," "containing," "involving," "holding," "composed of," and
the like are to be understood to be open-ended, i.e., to mean
including but not limited to. Only the transitional phrases
"consisting of" and "consisting essentially of" shall be closed or
semi-closed transitional phrases, respectively, as set forth in the
United States Patent Office Manual of Patent Examining Procedures,
Section 2111.03.
