Definitions

  • 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.
  • the present disclosure is directed to a long-life abrasive pad assembly.
  • 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.
  • the fastening material comprises loop fabric.
  • the material articles are composed of at least one of diamond, cubic boron nitride, aluminum oxide, silicon carbide, and garnet.
  • the substrate is composed of any of steel, brass, and aluminum.
  • a handheld tool assembly comprising: (a) a motor; (b) a fastening surface operably connected to the motor; and (c) an abrasive pad assembly, comprising: (i) an abrasive layer having first and second surfaces with the first surface being coated with material particles having predetermined hardness characteristics; (ii) 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 (iii) 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; wherein the fastening layer is removably connected to the fastening surface.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • a handheld device 18 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.
  • the abrasive pad 10 is capable of detachably securing to a rotating, member 24 of the device 18.
  • 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.
  • 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.
  • 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 .
  • inventive 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.
  • 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.
  • 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.
  • At least one of A and 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.
