Abstract

A scraper having a body portion with a front edge and a cover portion slidable relative to the body portion. The blade is received in the body portion with its cutting edge extending beyond the front edge of the body portion. The cover portion is movable relative to the body portion from a retracted position exposing the blade cutting edge to an extended position overlying the blade cutting edge. The cover portion is held in its retracted and/or its extended positions by locking mechanisms on the cover portion and on the body portion which cooperate with each other to hold the cover in its retracted and/or extended positions.

Claims

1. A scraper comprising a body portion having a front edge and a cover portion mounted on and slidable relative to said body portion, said cover portion having a blunt non-cutting forward edge, a blade receiving cavity in said body portion for receiving a blade with its cutting edge extending beyond the front edge of the body portion, said cover portion overlying said cavity in said body portion, said blade being interposed between said body portion and said cover portion, said cover portion being slidable relative to the body portion from a retracted position exposing the blade cutting edge to an extended position with the blunt non-cutting forward edge overlying and covering the blade cutting edge, first holding means for holding the cover portion in its retracted position, second holding means adapted to hold the cover portion in its extended position, said first holding means comprising locking means on the cover portion and first locking means on the body portion cooperating with each other to hold the cover portion in said retracted position, said second holding means comprising said locking means on said cover portion and second locking means on the body portion cooperating with each other to hold the cover portion in its extended position, said locking means on the cover portion comprises a protrusion, said first and second locking means on the body portion comprise first and second indentations, respectively, the first indentation being spaced from the second indentation, maintaining means for maintaining the cover portion over said body portion cavity, said maintaining means comprising lock lug means and lock tab means cooperating with each other, the blade receiving cavity in the body portion has a cavity floor, side walls and a rear wall having an opening therein, a lock finger is provided on said cover portion said lock finger is a resilient finger, said lock finger having said protrusion, said lock finger extends rearwardly from the cover portion, said lock finger is attached to a thumbpiece formed by a pair of slots cut in the cover portion, said lock finger has at least a portion extending through said opening in the rear wall of said cavity to a position below the body portion.

2. A scraper as set forth in claim 1 wherein said indentations are provided in said body portion.

3. A scraper as set forth in claim 2 wherein said indentations are longitudinally spaced from each other along said body portion and wherein said protrusion is insertable in one of the indentations depending on whether the cover is in its extended or retracted position.

4. A scraper as set forth in claim 3, wherein said lock tab means are on the cover portion and said lock lug means are on the body portion, said lock lug means are spaced above the cavity floor of the cavity in the body portion with said lock tab means mounted for slidable movement below said lock lug means, the thickness of said lock tab means is less than the thickness of the cover portion.

5. A scraper as set forth in claim 4 wherein the said lock tab means are shorter than the cover portion.

6. A scraper as set forth in claim 5 wherein said lock tab means are formed along sides of the cover portion.

7. A scraper as set forth in claim 6 wherein openings are formed in the cover portion adjacent the lock tab means.

8. A scraper as set forth in claim 7 wherein the lock lug means are formed adjacent the front edge of the body portion.

9. A scraper as set forth in claim 8 wherein said cover portion is movable to a removal position where the lock tab means are moved to a position forwardly of the lock lug means so that the openings are aligned with the lock lug means to permit the cover to be removed by moving the openings past the lock lug means.
