Claims
- 1. A sanding system comprising:
a) a relatively rigid rectangular backing plate having a pair of opposed parallel ends and first and second opposed surfaces, and provided on said first surface with a handle and means to support a sanding pad on said second surface; b) a deformable sanding pad with rectangular dimensions similar to those of the backing plate and a thickness that is not greater than the shorter of the rectangular dimensions and having at least one sanding surface, wherein the sanding pad further comprises a pair of opposed parallel ends and at least one of the pair of parallel ends comprises a groove; and c) at least one retaining means in communication with the backing plate having a generally L-shaped cross section with a plurality of projections extending from an end of the generally L-shaped cross section adapted at one end to pierce a side of the deformable sanding pad in the thickness direction through at least a portion of the groove.
- 2. The sanding system according to claim 1 in which the sanding pad is formed from a resilient open-celled foam.
- 3. The sanding system according to claim 1 in which the sanding pad is formed from a polyurethane foam.
- 4. The sanding system according to claim 1 wherein at least a portion of the generally L-shaped cross section of the at least one retaining means is generally parallel with at least a portion the groove in the sanding pad.
- 5. The sanding system according to claim 1 in which the sanding pad has from two to four sanding surfaces.
- 6. The sanding system according to claim 5 in which the sanding surfaces of the sanding pad have different sanding characteristics.
- 7. The sanding system according to claim 1 in which the at least one retaining means is formed integrally with the backing plate.
- 8. The sanding system according to claim 1 in which there are two retaining means.
- 9. The sanding system according to claim 1 wherein the handle is detachable.
- 10. The sanding system according to claim 9 wherein the detachable handle is replaced with a pole sanding mechanism.
- 11. A pad for a sanding system for sanding a surface, the sanding system having a relatively rigid rectangular backing plate having a pair of opposed parallel ends and first and second opposed surfaces and provided on said first surface with a handle and means to support a sanding pad on said second surface, and at least one retaining means in communication with the backing plate having a generally L-shaped cross section with a plurality of projection extending from an end of the generally L-shaped cross section, the pad comprising:
a) rectangular dimensions similar to those of the backing plate; b) a thickness that is not greater than the shorter of the rectangular dimensions; c) and having at least one sanding surface; d) the sanding pad having a pair of opposed parallel ends; and e) at least one of the pair of parallel ends comprises a groove.
- 12. The pad according to claim 11 in which the pad is formed from a resilient open-celled foam.
- 13. The pad according to claim 11 in which the pad is formed from a polyurethane foam.
- 14. The pad according to claim 11 in which the pad has from two to four sanding surfaces.
- 15. The pad according to claim 14 in which the sanding surfaces of the sanding pad have different sanding characteristics.
- 16. The pad according to claim 11 in which the sanding system comprises two retaining means and both parallel ends of the pad comprise a groove.
- 17. The pad according to claim 11 in which the pad has a first opposed surface and a second opposed surface offset from the first opposed surface forming a trapezoidal shaped pad.
- 18. The pad according to claim 11 in which a portion of the pad under the groove is any geometric shape.
- 19. The pad according to claim 11 comprising a first material and a second material.
