Title: Technologies for hand sanding

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present application is a continuation of U.S. Non-Provisional patent application Ser. No. 13/947,651, filed on Jul. 22, 2013, which claims priority from U.S. Provisional Patent Application Ser. No. 61/741,642, filed on Jul. 25, 2012, which is herein fully incorporated by reference for all purposes. 
    
    
     TECHNICAL FIELD 
     Generally, the present disclosure relates to hand sanding. More particularly, the present disclosure relates to hand sanding apparatuses. 
     BACKGROUND 
     In the present disclosure, where a document, an act and/or an item of knowledge is referred to and/or discussed, then such reference and/or discussion is not an admission that the document, the act and/or the item of knowledge and/or any combination thereof was at the priority date, publicly available, known to the public, part of common general knowledge and/or otherwise constitutes prior art under the applicable statutory provisions; and/or is known to be relevant to an attempt to solve any problem with which the present disclosure is concerned. 
     A typical hand sanding apparatus is a tool used for hand sanding a surface. One example of such surface is a profiled surface, such as a contoured molding surface. Often, such apparatus can be inadequate for hand sanding the profiled surface due to varying contouring curvature of the surface. Also, such apparatus can be inadequate for hand sanding the profiled surface due to poor ergonomics of such apparatus. Further, such apparatus can be structured such that a user is unable to hand sand the profiled surface in one movement, while applying pressure in a relatively uniform manner across the profiled surface. Such drawbacks become more pronounced when the user attempts to operate such apparatus for consecutively hand sanding a plurality of such profiled surfaces and/or hand sand the same profile surface several times, such as before, during, and/or after paint application. 
     While certain aspects of conventional technologies have been discussed to facilitate the present disclosure, no technical aspects are disclaimed. The claims may encompass at least one of the conventional technical aspects discussed herein.

     The terminology used herein can imply direct or indirect, full or partial, temporary or permanent, action or inaction. For example, when an element is referred to as being “on,” “connected” or “coupled” to another element, then the element can be directly on, connected or coupled to the other element and/or intervening elements may be present, including indirect and/or direct variants. In contrast, when an element is referred to as being “directly connected” or “directly coupled” to another element, there are no intervening elements present. 
     Although the terms first, second, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not necessarily be limited by such terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present disclosure. 
     The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be necessarily limiting of the disclosure. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “includes” and/or “comprising,” “including” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     Example embodiments of the present disclosure are described herein with reference to illustrations of idealized embodiments (and intermediate structures) of the present disclosure. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, the example embodiments of the present disclosure should not be construed as necessarily limited to the particular shapes of regions illustrated herein, but are to include deviations in shapes that result, for example, from manufacturing. 
     Any and/or all elements, as disclosed herein, can be formed from a same, structurally continuous piece, such as being unitary, and/or be separately manufactured and/or connected, such as being an assembly and/or modules. Any and/or all elements, as disclosed herein, can be manufactured via any manufacturing processes, whether additive manufacturing, subtractive manufacturing and/or other any other types of manufacturing. For example, some manufacturing processes include three dimensional (3D) printing, laser cutting, computer numerical control (CNC) routing, milling, pressing, stamping, vacuum forming, hydroforming, injection molding, lithography, and so forth. 
     Any and/or all elements, as disclosed herein, can include, whether partially and/or fully, a solid, including a metal, a mineral, an amorphous material, a ceramic, a glass ceramic, an organic solid, such as wood and/or a polymer, such as rubber, a composite material, a semiconductor, a nano-material, a biomaterial and/or any combinations thereof. Any and/or all elements, as disclosed herein, can include, whether partially and/or fully, a coating, including an informational coating, such as ink, an adhesive coating, a melt-adhesive coating, such as vacuum seal and/or heat seal, a release coating, such as tape liner, a low surface energy coating, an optical coating, such as for tint, color, hue, saturation, tone, shade, transparency, translucency, non-transparency, luminescence, anti-reflection and/or holographic, a photo-sensitive coating, an electronic and/or thermal property coating, such as for passivity, insulation, resistance or conduction, a magnetic coating, a water-resistant and/or waterproof coating, a scent coating and/or any combinations thereof.

     Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and should not be interpreted in an idealized and/or overly formal sense unless expressly so defined herein. 
     Furthermore, relative terms such as “below,” “lower,” “above,” and “upper” may be used herein to describe one element&#39;s relationship to another element as illustrated in the accompanying drawings. Such relative terms are intended to encompass different orientations of illustrated technologies in addition to the orientation depicted in the accompanying drawings. For example, if a device in the accompanying drawings is turned over, then the elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements. Similarly, if the device in one of the figures is turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. Therefore, the example terms “below” and “lower” can, therefore, encompass both an orientation of above and below. 
     If any disclosures are incorporated herein by reference and such incorporated disclosures conflict in part and/or in whole with the present disclosure, then to the extent of conflict, and/or broader disclosure, and/or broader definition of terms, the present disclosure controls. If such incorporated disclosures conflict in part and/or in whole with one another, then to the extent of conflict, the later-dated disclosure controls. 
       FIG. 1A  shows a front perspective view of an example embodiment of a hand sanding apparatus according to the present disclosure. 
     A hand sanding apparatus  100  includes a housing  102 , which houses a plurality of plates  112  therein. Housing  102  includes a U-shaped top portion defined via a pair of opposing end members  104  and a pair of opposing sidewalls  106  spanning between members  104  along a sanding direction. Note that, in some example embodiments, the U-shaped portion can include C-shape or V-shape. Housing  102  can be at least partially unitary. The top portion can be at least partially unitary. Housing  102  can include plastic, rubber, and/or any other material for enhanced ergonomics, while tolerating dirt, sweat, fine sanding particles, and so forth. 
     Members  104  can be identical and/or different from each other in shape, area, volume, structure, orientation, size, dimensions, and so forth. Sidewalls  106  can be identical and/or different from each other in shape, area, volume, structure, orientation, size, dimension, and so forth. Members  104  and sidewalls  106  are continuous with each other. Members  104  have a pair of top surfaces  108  extending along the sanding direction. Such extension can be along at least partial longitudinal extension of members  104  along the sanding direction. Surfaces  108  are also spanning between sidewalls  106  to provide for hand placement support along said direction. Such spanning can be along at least partial lateral extension of members  104 . Surfaces  108  can be identical and/or different from each other in shape, area, volume, structure, orientation, size, dimension, and so forth. Surfaces  108  are outwardly arcuate along the sanding direction between sidewalls  106 . Such arching can be in an identical or different manner, whether in size, structure, orientation, shape, texture, and so forth. Such arching can include corner portions of members  104 . Surfaces  108  can be outwardly arcuate diagonal to the sanding direction. Such arching can be in an identical or different manner, whether in size, structure, orientation, shape, texture, and so forth. Such arching can include corner portions of members  104 . 
     Members  104  partially overlay plates  112  along the sanding direction and between sidewalls  106 . Such overlay limits movement of plates  112  at least past surfaces  108  in a direction at least perpendicular to the sanding direction. Note that such overlay can also limit movement of plates  112  at most past surfaces  108  in the direction at least perpendicular to the sanding direction. Also, note that members  104  function as closed end tunnels for plates  112  such that plates  112  are limited in the movement along the sanding direction via members  104  and at least perpendicular to the sanding direction via roofs of members  104 , which have surfaces  108  thereon. Further, note that members  104  have a pair of walls  108 . 1  spanning between sidewalls  106  and continuous with surfaces  108 . Walls  108 . 1  can be identical and/or different from each other in shape, area, volume, structure, orientation, size, dimension, and so forth. Walls  108 . 1  can extend away from surfaces  108  up to sidewalls  106  or less. In other example embodiments, at least one of walls  108 . 1  is lacking and plates  112  rise up at most to surface  108  where the one of walls  108 . 1  is lacking. 
     Members  104  and sidewalls  106  define a top portion interior space  110 , which is sized for housing plates  112  adjacent to each other as plates  112  extend in the sanding direction. Space  110  can be of any shape, whether sharp angled, curve angled, rounded, and so forth. For example, space  110  can be a polyhedron, an ellipsoid, a cuboid, and so forth. Members  104  and sidewalls  106  define an upper opening  114  therebetween. Opening  114  can be of any shape, such as a polygon, a parallelogram, a quadrilateral, a triangle, an ellipse, a star, a U-shape, a V-shape, a C-shape, and so forth. Opening  114  provides access to space  110 . Opening  114  is sized to provide partial access to plates  112  such that a plurality of top surfaces of plates  112  is accessible, such as via sight, touch, and so forth. Such partial access enables manual positioning adjustment of plates  112  via the top surfaces of plates  112 . For example, a user can apply force through opening  114  onto the top surfaces of plates  112  to move plates  112  vertically away from opening  114  for sanding of a profiled surface. Such force can include finger pushing the top surfaces. 
     Housing  102  further includes a pair of opposing T-shaped members  116 . Each of T-shaped member  116  is defined via a pair of arms  120  extending from a leg  118 . Arms  120  can be identical and/or different from each other in shape, area, volume, structure, orientation, size, dimension, and so forth. Legs  118  can be identical and/or different from each other in shape, area, volume, structure, orientation, size, dimension, and so forth. Legs  118  extend from members  104  such that arms  120  face each other. Surfaces  108  are continuous with exterior leading surfaces of legs  118 , which can be identical to and/or different from each other in shape, area, volume, structure, orientation, size, dimension, and so forth. T-shaped members  116  can be at least partially unitary. T-shaped members  116  can be at least partially unitary with the U-shaped top portion. At least one of arms  120  avoids extending away from at least one of legs  118  past sidewalls  106 . 
     Housing  102  also includes a pair of opposing side members  122  spanning between arms  120  along the sanding direction. Members  122  can be identical and/or different from each other in shape, area, volume, structure, orientation, size, dimension, and so forth. Members  122  and T-shaped members  116  define a lower opening therebetween. The lower opening is greater in area than opening  114 . The lower opening provides access to space  110 . The lower opening is sized such that plates  112  are output therethrough. T-shaped members  116  and members  122  can be at least partially unitary. Note that in other example embodiments, apparatus  100  can lack at least one member  122 . 
     Within housing  102 , one of side members  122 , the U-shaped top portion, and T-members  116  define a recessed side opening  124  extending along the sanding direction. Opening  124  can be of any shape, size, orientation, direction, area, and so forth. Opening  114  is shorter in length along the sanding direction than opening  124 . Opening  114  can extend along the sanding direction at most equivalent to opening  124 . Opening  114  avoids extending past opening  124  along the sanding direction at least on one side of opening  124 . Note however, that opening  114  can extend along the sanding direction longer than opening  124  and can extend past at least one side of opening  124 . Note that in other example embodiments, opening  124  can be lacking. Also, in other example embodiments, opening  124  can be non-recessed, flush with one of sidewalls  106 , protruding past one of sidewalls  106 , and so forth. Opening  124  can be inclined towards and/or away from plates  112 . 
     Another one of members  122  is continuous with the U-shaped top portion via a recessed sidewall  126 , which has a shaft opening therethrough. Sidewall  126  opposes opening  124 . Sidewall  126  can be identical to and/or different from opening  124  is size, shape, structure, area, orientation, and so forth. Opening  124  is more recessed inward than sidewall  126 , although in other example embodiments such recessing can be reversed or identical. Note that in other example embodiments, sidewall  126  can be non-recessed, flush with one of sidewalls  106 , protruding past one of sidewalls  106 , and so forth. Sidewall  126  can be inclined towards and/or away from plates  112 . 
     Plates  112  are adjacently positioned next to each other and are flat. Plates  112  can be non-flat as well. Plates  112  can be identical to and/or different from each other in shape, area, volume, structure, orientation, size, dimensions, abrasive properties, and so forth. Although plates  112  are rectangular, plates  112  can be of any shape, such as a polygon, a parallelogram, a quadrilateral, a triangle, an ellipse, a star, and so forth. Plates  112  can be positioned to at least partially fill space  110  between sidewalls  106 . 
     Apparatus  100  also includes a flat spring  128 , which is stationed along sidewall  126 . Spring  128  has a slot having a wider portion and a narrower portion. Plate  128  has a tab for manual pulling. Note that in other example embodiments, apparatus  100  lacks spring  128 . Note that in yet other example embodiments, apparatus  100  uses another locking technology, such as fastening, mating, interlocking, and so forth. 
     Apparatus  100  also includes a block  130 , which is sized for at least partially conforming to opening  124  to at least partially fit thereinto. Block  130  contains an opening therethrough. The opening is sized for a shaft. Block  130  can be of any length, width, height, volume, area, shape, and so forth. Block  130  can be shaped as a plate, such as one of plates  112 . Block  130  can be linear, curved, rigid, flexible, cushioned, energy absorbent, and so forth. Block  130  can have at least one valley and/or a hill. Block  130  can be flush and/or non-flush with at least one of legs  118 . Block  130  can be flush and/or non-flush with one of sidewalls  106 . Block  130  can be flush and/or non-flush with one of members  122 . Note that in other example embodiments, apparatus  100  lacks block  130 . Note that in some example embodiments, block  130  can function as one of plates  112 . 
     Apparatus includes a shaft having a lever  132  coupled thereto via a pin  134 . Shaft  132  can be of any type. Pin  134  can be of any type. Lever  132  can be of any type. In other example embodiments, lever  132  can be coupled to the shaft without pin  134 . Block  130  is between lever  132  and plates  112 . Lever  132  can pivot at least between a first position, such as for locking plates  112  in their respective vertical positions, and a second position, such as for unlocking plates  112  from their respective at least vertical positions. Lever  132  avoids extending past the one of sidewalls  106 , above lever  132 , when in locked position. However, note that in other example embodiments, lever  132  extends past the one of sidewalls  106 , above lever  132 , when in locked position. Also, note that in other example embodiments, plates  112  are locked without using lever  132 , such as when lever  132  is lacking. Note that when more than one lever  132 , pin  134 , and the shaft is used, then levers  132 , pins  134 , and/or the shafts can be respectively identical and/or different from each other in shape, area, volume, structure, orientation, size, dimension, and so forth. 
     Note that housing  102  can have at least one bridge and/or at least one handle extending and/or spanning between members  104  over opening  114 . Such bridge and/or handle can extend and/or span from surfaces  108  or below surfaces  108 , yet above plates  112 . Such bridge and/or handle can contact plates  112 . Such bridge and/or handle can extend diagonally and/or along the sanding direction. Such bridge and/or handle can be linear, curvy, and so forth. Such bridge and/or handle can be of any type. Such handle can also be coupled to one of members  104  only. Such handle can also be coupled to at least one of sidewalls  106 . Such handle can further be coupled to any portion of T-shaped members  116  and/or members  122  in any way.

     Member  206  is within space  110 . Some examples of member  206  include a plate, a shaft, a rod, a block, and so forth. Member  206  is operably coupled to knob  202 . Member  206  extends within space  110  between sidewalls  106  and can span between sidewalls  106 . Member  206  can be of any shape, size, area, structure, orientation, and so forth. Member  206  contacts plates  112  in a direction different from the sanding direction. 
     Ledges  204  extend from legs  118  such that legs  118  and ledges  204  are L-shaped toward plates  112 . Ledges  204  and ledges  118  can be an assembly and/or at least partially unitary. Ledges  204  can be identical to and/or different from each other in shape, area, volume, structure, orientation, size, dimensions, and so forth. Member  206  can vertically extend between one of ledges  204  and an interior surface of member  104  opposing surface  106 . 
     Plates  208  are T-shaped, as defined via a pair of arms extending from a leg, which can be used for sanding, whether directly and/or indirectly. Plates  208  are adjacently positioned next to each other and are flat. Plates  208  can be non-flat as well. Plates  208  can be identical to and/or different from each other in shape, area, volume, structure, orientation, size, dimensions, abrasive properties, and so forth. The arms and/or the legs can be identical to and/or different from each other in shape, area, volume, structure, orientation, size, dimensions, and so forth. Plates  208  can be positioned to at least partially fill space  110  between sidewalls  106 . Ledges  204  limit movement of plates  208  at least perpendicular to the sanding direction away from opening  114  such that ledges  204  and the arms of T-shaped plates are in contact with each other during such limitation. 
     In one example mode of operation, upon rotation of knob  202  in one direction, such as clockwise, member  206  applies pressure at least to the arms of plates  208  via tightening/clamping to fix plates  208  in their respective vertical positions, which can be vertically pre-adjusted via opening  114 . Likewise, upon rotation of knob  202  in another direction, such as counterclockwise, within space  110 , member  206  withdraws pressure from plates  112  via un-tightening/unclamping to unfix plates  112  from their respective vertical positions, such as for vertical plate position readjustment.

       FIG. 8  shows a front perspective view of an example embodiment of a flat spring according to the present disclosure. Some concepts depicted in this figure are described above. Thus, same reference characters identify same or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication. 
     Spring  128  has tab  138  structured for user pulling in the sanding direction. Tab  138  has at least one ridge  148  thereon. When more than one ridge  148  is used, then ridges  148  can be identical to and/or different from each other, whether in size, structure, area, orientation, shape, and so forth. Spring  128  has at least one slot  140  with a wider portion  142  and the narrower portion  144 . When more than one slot  140  is used, then slots  140  can be identical to and/or different from each other, whether in size, structure, area, orientation, shape, and so forth. T-end  136  is input into wider portion  142  and then slid to narrower portion  144 , which prohibits T-end  136  from removal therefrom. Spring  128  also has an outwardly projecting curve  146 , which is bent inward closer to plates  112  when T-end  136  is clamped/tightened via lever  132  operated into the locking position. 
       FIG. 9  shows a back perspective view of an example embodiment of a hand sanding apparatus being coupled to a flat spring according to the present disclosure. Some concepts depicted in this figure are described above. Thus, same reference characters identify same or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication. 
     Sidewall  126  has at least one opening through which T-end  136  of shaft  140  projects out of. Spring  128  is placed adjacent to sidewall  126  such that T-end  126  is input into wider portion  142  of slot  140 . Spring  128  is then moved along the sanding direction such that T-end  136  is slid into narrower portion  144 , which prohibits T-end  136  from being removed therefrom. Note that lever  132  is extending past one of sidewalls  106  and is in the unlocked position. When lever  132  is operated into the locked position, such as in  FIG. 6B , T-end  136  pulls curve  146  toward plates  112  thereby fixing plates  112  in their respective vertical positions at least for the operated lever  132 .
