- B24D 15/023: {using in exchangeable arrangement a layer of flexible material}
- B24D: TOOLS FOR GRINDING, BUFFING OR SHARPENING (abrading-bodies specially designed for tumbling apparatus, e.g. abrading-balls B24B31/14; honing tools B24B33/08; lapping tools B24B37/11)

## Abstract

A sanding device for sanding substantially planar surfaces and substantially non-planar surfaces including a first section and a second section releasably coupled thereto. The second section for supporting a piece of sandpaper having ends captured between the engagement of the first and second sections. The first section also capable of being used for retaining sandpaper absent the second section.

## Claims

### Claim 1

A sanding device for retaining a piece of sand paper comprising:
a first section having the general shape of a channel including spaced apart sidewalls in a generally outwardly divergent and outwardly biased relationship, the sidewalls each terminating in an end and movable between an inwardly compressed position and an outwardly biased position; and
a second section including a base having a first surface, an opposing second surface, and spaced apart engagement members extending upwardly and inwardly convergent from the first surface for receiving the ends of the first section therebetween with the sidewalls in the inwardly compressed position and retaining the ends with the sidewalls in the outwardly biased position, ends of the piece of sandpaper being receivable between respective ends of the first section and the engagement members and retained thereby with the sidewalls in the outwardly biased position, the base of the second section being substantially rigid and the first surface including abutments inwardly adjacent engagement members for receiving the ends of the sidewalls there against to prevent movement of the sidewalls to the inwardly compressed position during sanding procedures.

### Claim 2 (depends on 1)

A sanding device as claimed in claim 1 wherein the ends of the sidewalls of the first section each include a sandpaper engagement element for receiving the edges of a piece of sandpaper in the inwardly compressed position and tautly retaining the sandpaper therebetween in the outwardly biased position in the absence of the second section.

### Claim 3 (depends on 2)

A sanding device as claimed in claim 2 wherein the sandpaper engagement elements are generally hook shaped to form upwardly directed slots for receiving the edges of the piece of sandpaper.

### Claim 4

A sanding device for sanding substantially planar surfaces and substantially non-planar surfaces comprising:
a first section having the general shape of a channel including spaced apart sidewalls in a generally outwardly divergent and outwardly biased relationship, the sidewalls each terminating in an end and movable between an inwardly compressed position and an outwardly biased position;
a second section including a base having a first surface, an opposing second surface, and spaced apart engagement members extending upwardly and inwardly convergent from the first surface for receiving the ends of the first section therebetween with the sidewalls in the inwardly compressed position and retaining the ends with the sidewalls in the outwardly biased position, the base of the second section being substantially rigid and the first surface including abutments inwardly adjacent engagement members for receiving the ends of the sidewalls there against to prevent movement of the sidewalls to the inwardly compressed position during sanding procedures; and
a piece of sandpaper having opposing edges, the piece of sandpaper traversing the second surface of the base with the edges of the piece of sandpaper being received between respective ends of the first section and the engagement members and retained thereby with the sidewalls in the outwardly biased position.

### Claim 5 (depends on 4)

A sanding device as claimed in claim 4 wherein the ends of the sidewalls of the first section each include a sandpaper engagement element receiving the edges of the piece of sandpaper in the inwardly compressed position and tautly retaining the sandpaper therebetween in the outwardly biased position in the absence of the second section.

### Claim 6 (depends on 5)

A sanding device as claimed in claim 5 wherein the sandpaper engagement elements are generally hook shaped to form upwardly directed slots receiving the edges of the piece of sandpaper.
