FIGS. 4 , 5 and 6 in which a drywall pole sander, generally indicated as 100 constructed in accordance with the invention is provided.Pole sander 100 includes apole 5 terminating at a pivot 6. Pivot 6 pivots about pole sander or may be maintained in a fixed relationship topole 5. Abase 7 is affixed to pivot 6 and supports asanding head 12 thereon. -
Sanding head 12 is affixed tobase 7. In a preferred, non-limiting embodiment,sanding head 12 has a generally rectangular shaped body with parallel opposed sides defining a width and a length. In a preferred embodiment, to conform to thebase 7 as known in the art, thesanding head 12 has a length greater than its width. However, this is not a requirement. - As more particularly seen in
FIG. 6 ,sanding head 12 has abulk member body 13 formed as a bulk material for supporting anabrasive material 14, formed as particulate, which are substantially uniformly disposed here throughout for at least several layers. -
Abrasive material 14 is also disposed on at least an upper (away from base 7) surface ofmember body 13. Because of the substantially uniform distribution ofabrasive material 14 withinbulk member body 13,abrasive material 14 forms de facto layers, coplanar withbase 7, withinbulk member body 13. It should be noted that theabrasive material 14 may be uniformly distributed throughout the entire thickness ofbulk member 13 ofsanding head 12, but is not required for the invention. What is required is that unlike sandpaper, there are several layers in addition to anouter surface 15 containingabrasive material 14. Alternatively,bulk member body 13 may be formed entirely of an abrasive material, or may be textured as asanding surface 15 to provide the abrasive properties. - The bulk material forming
bulk member 13 ofsanding head 12 may be formed of a non paper material such as an epoxy resin, shellac, urethane, polyurethane, urethane rubber, urethane plastic and the like, that is capable of holding anabrasive material 14 in suspension withinbulk member body 13 to enable sanding bysanding head 12 when utilized as part ofpole sander 100.Abrasive material 14 may be sand, diamond dust, aluminum oxide, calcite or other abrasives that are known to sand drywall while being capable of being distributed within one or more of the bulk materials ofbulk member 13 described above. - Reference is now made to
FIG. 1 andFIG. 2 showing thesanding head 12 constructed in accordance with one embodiment of the invention. In this embodiment of the invention,sanding surface 15 is formed into a pattern. In this pattern, the sanding surface is formed by way of one example, squares rotated 45 degrees relative to the sides ofbulk material member 13. Theabrasive material 14 is within eachindividual square 16 providing a substantially or relatively abrasivefree area 17 as compared to within the squares which may be formed as grooves. In this embodiment, the rotation ofsquares 16 facilitates the sanding of an inside corner where the abrasive material may cut grooves rather than provide uniform sanding. - Additionally, the abrasive
free regions 17, when formed as grooves channel the resulting dust away from theabrasive square 16 during sanding, preventing the dust from building up or caking; maintaining the efficiency ofsanding head 12. The thrust of the stroke ofdrywall sander 100 against the wall pushes the resulting drywall dust away from the pad from thegrooves 17. - In one preferred but non-limiting embodiment,
sander head 12 includes asidewall 2 having a length of about 3.5 inches and alonger sidewall 3 having a length of about 9½ inches. In a preferred embodiment, the thickness 4 ofsanding head 12 is about 0.25 inches.

head 112 includes abulk member 113. As described above,bulk member 113 may be formed entirely of an abrasive material, may be textured at asanding surface 115, or may includebulk material 113 with layers of abrasive materials distributed there throughout as discussed above. - First and second straps of
flexible material 114 are provided on opposed edges ofbulk member 113. In a preferred, but non-limiting embodiment, strips 114 are made from nylon.Strips 114 may be fastened tobulk member 113 with any type of fastening structure known such as glue, other adhesives, screws, but in a preferred, non-limiting embodiment, strips 114 are embedded inbulk material 113 during the formation ofbulk material 114 so as to be an integral part of sandinghead 112. - Sanding
pole base 7 may be provided with clampingstructures 120 which may take the form of a butterfly clamp structure, spring bias clamp, or the like on the surface ofbase 7 which is affixed topole 5. In this way, during use, abottom surface 111 of sandinghead 112 comes into contact withbase 7 such thatouter surface 115 faces away frombase 7.Strips 114 are then brought about and behindbase 7 where they are clamped tobase 7 byrespective clamps 120holding sanding head 112 in place withinbase 7. - As a result of utilizing a sanding head formed of a bulk material for having an abrasive material distributed within the bulk material which wears away during use, the sanding head no longer tears. Furthermore, because as
top surface 15 wears away, it is replaced by the underlying bulk material and abrasive material as described above, the longevity of the sandinghead 12 increases significantly to as many as 1000 times greater than the sanding life of conventional sand paper reducing the number of times head 12 must be replaced. The bulk material may have a thickness substantially greater than the thickness of a sheet of sandpaper further producing the number of times that the sandinghead 12 must be replaced. - While this invention has been particularly shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention encompassed with the appending claims.
