[0023] Referring to FIGS. 1-3, various views of a hand-held sanding tool (hereinafter referred as “sanding tool”) 100, according to an embodiment of the present invention. The sanding tool 100 is used for sanding/polishing various objects. In one embodiment, the sanding tool 100 is an intelligent and unique polishing product that has been designed to clean or sand various surfaces such as saw cuts quick (rough or finish), ease edges, flat plane sanding, contour sanding, reach sanding for hard-to-get spots. The sanding tool 100 is designed to fit in the hand as well as the tool bucket or the job to work on the shop or out in the field. In one embodiment, at least two sanding tools 100 are used, where one is for rough and another is for finished work.

[0024] In one embodiment, the sanding tool 100 comprises one or more components including a first sanding member or a machined sanding block 104, a second sanding member or a detachable wedge-shaped part 106 aligned with the machined sanding block 104, and a sanding belt 102 that wraps around the machined sanding block 104 and the wedge-shaped part 106. In one embodiment, the detachable wedge-shaped part 106 is used to tighten the sanding belt 102 in place. In one embodiment, the sanding belt 102 is an abrasive material that is installed on the machined sanding block 104. In one embodiment, the machined sanding block 104 has finger grips 110 on its front surface for easy handling. The wedge-shaped part 106 is a machined or milled, half-rounded wedge-shaped sanding member that slides against the machined sanding block 104 to tighten the sanding belt 102 in place.

[0025] In one embodiment, the sanding tool 100 further comprises a high-density foam cushion or a memory foam 108 glued to another side of the machined sanding block 104 for expansion. In one embodiment, the machined sanding block 104 along with the foam cushion 108 is inserted into the sanding belt 102. In one embodiment, the foam cushion 108 allows different minor belt measurements. In one embodiment, the foam cushion 108 expands to maintain tightness of the sanding belt 102 tightness.

[0026] In one embodiment, the sanding tool 100 is a two-part sanding block that uses a wedge principle for making the sanding belt 102 to stay in place. In one embodiment, the wedging principle keeps the sanding belt 102 snugs for a full flat sanding surface to work with any surfaces. In one embodiment, the sanding tool 100 is utilized for cleaning saw cuts (rough or finished), ease edges, flat plane sanding, contour sanding, reach sanding for hard-to-get spots. In some embodiments, the sanding tool 100 is utilized for sanding of wood, plastics, plasters, drywall, masonry steel, marine, sculpture, auto bodywork, and glass work.

[0027] Referring to FIGS. 4-6, the sanding tool 100 with a slightly moved detachable wedge-shaped part 106, according to one embodiment of the present invention. In one embodiment, the sanding belt 102 is a standard 3″×21″ sanding belt. In one embodiment, the sanding belt 102 is a sandpaper belt originally made for power sanders. In one embodiment, the machined sanding block 104 and wedge-shaped part 106 are disposed inside the sanding belt 102.

In one embodiment, the machined sanding block 104 and the wedge-shaped part 106 further includes a marking 114 on any one side for indicating the top surface. In one embodiment, the marking may be “T” label. The marking “T's” are used for facing up the machined sanding block 104 and the wedge-shaped part 106 when at work. In one embodiment, the “T” label in the movable wedge-shaped part 106 is aligned with the “T” label in the sanding block 104. In one embodiment, the small wedge-shaped part 106 pops out by pressing the other side of the “T” label.

[0028] Referring to FIGS. 7-10, aligning or positioning the components of the sanding tool 100, according to one embodiment of the present invention. In one embodiment, the wedge-shaped part 106 includes a rounded-side 116 and a flat surface 118. In one embodiment, the rounded-side 116 is placed facing outward and the flat surface 118 is aligned with the machined block 104. In one embodiment, the wedge-shaped part 106 is placed with facing the “T” marking 114 upwards. In one embodiment, the wedge-shaped part 106 is a pop-out structure for easy change of sanding belts 102. In one embodiment, the wedge-shaped part 106 slides inside the sanding belt 102 against the machined sanding block 104 to tighten the sanding belt 102 in place.

[0029] In one embodiment, the one or more components of the sanding tool 100 are aligned or positioned inside the sanding belt 102. At one step, an open side of the sanding belt 102 is placed upon a flat surface. In one embodiment, the sanding belt 102 is a standard 3″×21″ sanding belt. At another step, the large part, i.e., the machined sanding block 104 is inserted into the open side of the sanding belt 102 with “T” marking 114 facing up. In one embodiment, the “T” marking 114 indicates for the top facing of the machined sanding block 104. At another step, the small wedge-shaped part 106 is inserted into the open side of the sanding belt 102 with “T” marking 114 facing up such that the rounded-side 116 out facing the end of the sanding belt 102 and the flat surface aligned with the machined sanding block 104 of the sanding tool 100 i.e., “T” to “T”. In case of removing the small wedge-shaped part 106, the sanding tool 100 is placed on a flat surface with the “T's” 114 facing down and the small wedge-shaped part 106 hanging beyond the edge of the flat surface. Then take a small wood drift and hammer and tap out the small wedge-shaped part 106. In one embodiment for a smooth wedge in and out operation, bar soap is rubbed on inner wedge surfaces and on rounded end surfaces.

[0030] Referring to FIG. 11, exemplarily illustrates the sanding tool 100 sands an object 112 in a typical use case, according to one embodiment of the preset invention. In one embodiment, the machined sanding block 104 and the wedge-shaped part 106 includes a marking 114 on any one side for indicating the top surface. In one embodiment, the marking may be “T” label for facing up the machined sanding block 104 and the wedge-shaped part 106 when at work. The moved wedge_wedge-shaped part 106 is aligned to the machined sanding block 104 by pressing on the “T” label. The sanding tool 100 polishes flat or curved surface of the object 112. The sanding tool 100 provides a single smooth surface for even flat sanding as well as rounded end for curved surfaces.

[0031] Advantageously, the sanding tool of the present invention is a simple tool for sanding various objects without using any mechanical parts or springs. The wedge-shaped part of the sanding tool tightens the sanding belt in place. The wedge-shaped part keeps the sanding belt in place to avoid any slippage or movement of the sanding belt for more even sanding. Further, the wedge-shaped part is a pop-out wedge-shaped part that allows for easy change of belt. The sanding tool available in the shop or out in the field is the durable block sander of choice. The sanding tool provides a flat even surface without any dips. Further, the sanding tool has a single smoothing surface for even sanding as well as rounded end sanding for curved surfaces. Also, the sanding belt is easy to change.
