Abstract
An erasable writing tablet for notation of dimensions and other information. The erasable writing table is adapted to be attached to a tape measure or any other conforming receptive surface. The material composition of the erasable writing tablet is sold under the trade name "Corian". The abrasiveness of this material permits the effacement of the notations by sandpaper or an eraser while maintaining the desired surface properties of the erasable writing tablet. A storage pocket is adapted to receive the means for effacing writing on the erasable writing tablet.
Claims9
A tape measure comprising:
- (a) a housing having an outer flat surface,
- (b) a measuring tape coiled and enclosed in said housing, the tape being extendable and retractable into the housing, and
- (c) a writing tablet formed of a solid and rigid polymer block with abrasive properties, the abrasive properties being a characteristic of the tablet's composition which contains inorganic filler of abrasive particles, the tablet having an inner surface, an edge surface and a flat outer surface, said inner surface being attached to said outer flat surface of the housing, the tablet being sufficiently hard and abrasive to permit said outer surface to be inscribed by a standard graphite pencil, said tablet being softer than sandpaper to enable the inscribed outer surface to be abraded with sandpaper, whereby the outer surface is renewed and receptive to further inscription after subsequent and repeated abrading by sandpaper.
A tape measure comprising a housing having an outer flat surface and a writing tablet, said writing tablet being formed by a solid and rigid polymer block with abrasive properties, the abrasive properties being a characteristic of the writing tablet's composition which contains a uniformly dispersed inorganic filler of abrasive particles, the writing tablet having an inner surface, an edge surface and a flat outer surface, the writing tablet being sufficiently hard and abrasive to enable said outer surface to be inscribed on by a standard graphite pencil, said writing tablet being softer than sandpaper to enable the inscribed outer surface to be abraded with sandpaper, whereby said outer surface is renewed and receptive to further inscriptions after subsequent and repeated abraiding by sandpaper.
