Corners and edges are especially difficult because of the fact that two or three perpendicular surfaces are being treated. In some situations, only one of the surfaces needs treatment, but often both surfaces need treatment.
- Although the tool or tool system referred to in the present application is referred to as a “sander” which uses “sandpaper”, it will be recognized that other abrasive papers, abrasive materials, or abrasive systems or the like can be used to replace the “sandpaper” referred to without loss of generality.
- The preferred system is a sanding system which can be useful for sanding adjacent perpendicular or nearly perpendicular surfaces simultaneously, which can be configured for variations in the angle between the surfaces. The present sanding system allows for providing sanding pads configured to treat two or more adjacent surfaces where the surfaces to be treated lie in different planes or are substantially perpendicular. Each sanding pad has two or more abrasive surfaces lying in different planes. The relative angles of the abrasive surfaces is variable, and the abrasive material may be selectively removed so that at least one surface of the pad is smooth and can be used as a guide placed against one of the adjacent surfaces, this allowing the sander to operate as an edging tool.
- Referring now to
FIGS. 1-4 the apparatus is essentially a conventional sander with a plurality of interchangeable sanding pads. To accomplish this, the present sanding apparatus preferably includes a pad frame system comprising a corner or detail pad frame for supporting a corner or detail pad for sanding into corners, and a plurality of profiled pad frames for supporting profiled pads configured to power sand simultaneously in two different planes regardless of the angle between adjacent work surfaces. The sanding pads are attached to the pad frame in any of several well known ways. A key aspect of the invention is that the profiled pads may have one or more generally vertical or angled (with respect to an upright sanding mechanism positioned for a sanding operation) abrasive surfaces, with one or more of the surfaces deliberately left smooth so as to provide a guide surface as described in more detail later. - The preferred sander comprises a
sander body 50 which houses a motor 52 (seeFIG. 1 ) coupled to an in-lineoscillating mechanism 54. - A preferred sanding pad frame such as
frame 56 and sanding pad such as 56A may be coupled to an in-line oscillating mechanism such as 54 for movement in a linear oscillating motion. Theframe 56 may be rotated about the axis (before attaching) of the oscillating arm to allow the user more orientation options. Such a sanding pad orpad frame 56, which is sometimes referred to in the present application as a corner or detail sanding pad or pad frame, typically has a substantially flat horizontally disposedlower surface 58 and a substantially pointed front portion 60 bounded laterally by vertically disposed sanding pads 56A which are positioned at a relative angle of less than 90 degrees. Thus with this configuration, withabrasive material 64 positioned onlower surface 58, and at least one pad 56A the apparatus can be used to sand a corner of a workpiece or two adjacent non-parallel surfaces such as a wall and ceiling. If positioned in a corner, the device 10 could simultaneously abrade a floor and two walls if positioned in a corner. In one embodiment, thebottom surface 58abrasive material 64 may be removed so thatlower surface 58, which is then smooth, may be used as a guide to slide along, e.g., the floor or other adjacent non-parallel surface while treating the lower edge of a wall. If both the floor and the wall need to be treated,pads 56A and 64 simultaneously abrade both, e.g., a floor and a wall or any two perpendicular surfaces simultaneously. The user may select fromframes 56 having one, two, or more angled abrasive surfaces, with one or more of the non-abrasive surfaces functioning as guide surfaces to guide the sander along it intended path as will be discussed below. -
FIG. 3A ,FIG. 3B , andFIG. 3C show a different embodiment of pad configuration. This embodiment, generally indicated by the numeral 100 attaches to a rectangular frame and is useful for sanding within multiple parallel grooves simultaneously, or sanding around multiple parallel protrusions. Thefirst pad 102 can be used to sand within grooves, while thesecond pad 104 is useful for sanding around multiple parallel protrusions. Thepads -
FIG. 4A ,FIG. 4B , andFIG. 4C show an extending arm for use with the sanding apparatus. Thearm 200 includes a frame -
attachment portion 202 and apad attachment portion 204. The frame attachment portion attaches to the sander, with sanding pad 56A andframe 56 attached to pad attachment portion. - Referring now to
FIGS. 5-7 another embodiment of the sanding apparatus, indicated by thenumber 300 is shown. Theapparatus 300 is particularly useful for forming shaped voids in 10 suitable substrates such as wood.FIG. 7 shows the type of void contemplated by the present invention. Aninitial opening 302 allows for accessing the interior of thesubstrate 304 so that the tool can form a complex shape such as thebowl shape 310. - The
tool 320 has anapplicator 321 with a tapered conical shape which may terminate at a point to form a drill type tip.Abrasive material 322 is positioned on theapplicator 321 which may alternatively be formed of metal with an abrasive surface such as diamond dust. Theapplicator 321 is connected to or replaces the oscillating spindle of anoscillating sanding apparatus 340 which includes amotor 342 and corresponding mechanical linkage. Thespindle portion 344 of theapplicator 321 may be articulated (need to show how) to allow for manipulation of the applicator to form the complex shapes as shown inFIG. 7 . - In use, a user first uses applicator to form opening 302. Once the opening is formed the user may then use
applicator 321 to form shapes. The size and shape of applicators may be varied and, theapplicator 321 may be under robotic control to allow for reliably recreating complex voids. - Referring now to
FIG. 8A -FIG. 8S show various arrangements of sanding pad frames 400-412 and corresponding contoured sanding pads 414-426 which operate in the manner described above in reference toFIGS. 1-4 . It can be seen that sanding pads 414-426 have between 2 and 4 vertical abrading surfaces 430, withsurfaces 430 selectively covered with abrasive material to allow for treating angled adjacent surfaces simultaneously as described above. Thesurfaces 430 may be varied with respect to height or length to fit a particular job. Sanding pads 414-426 are all formed ofmain bodies 440 havingabrasive surfaces 430 formed thereon, themain bodies 440 separable from frames 400-412 so as to be connected to an oscillating mechanism using means as would be apparent to one of skill in the art. -
Surfaces 430 may have different grades of abrasives positioned thereon so that for a four sided sanding pad such as that shown inFIG. 8G eachside 430 may have a different grade abrasive so that themain body 440 can be rotated to apply a desired abrasive without having to change the sanding pad/applicator. -
FIG. 8H-J show variousmain bodies 440 withabrasive surfaces 430 which may be connected to oscillatingmechanism 54 and oriented variously as shown.FIGS. 8K and 8L show a mechanism with asanding pad 450 connected directly and using apad frame 452 respectively. -
FIG. 9 shows anabrasive sphere assembly 500 that can be used with anoscillating mechanism 54 to create or polish a substrate 502 as shown. Theabrasive surface 530 covers the entire sphere as shown but again could cover half or less as discussed above. In order to uniformly produce complex voids 504 the mechanism may include a robotic mechanism to allow for numerical control. -
FIG. 10 shows an aspirator element 550 which may be used with oscillator mechanism. The element may be used to supply cooling fluid or gas as would be apparent to one of skill in the art. - Any variations and any combinations of the above teachings are also intended to be covered by this patent application.
