Abstract
A magic drawing board comprises a base, an opaque sheet mounted on the base, a flexible transparent sheet anchored along one edge thereof to the base, and a coupling mechanism comprising a coupling element on the base and a mating coupling element on the opposite edge of the transparent sheet for locating the transparent sheet in superposed position on the opaque sheet under uniform tension over the area of superposition, resulting in a higher quality image.
Claims1
A magic drawing board comprising a base having an upper surface, an opaque sheet mounted on the upper surface of the base, a flexible transparent sheet having one edge thereof permanently anchored to the base, and a detachable coupling mechanism including a first coupling element comprising a recess in the upper surface of the base and a mating coupling element comprising an elongated plastic molding along an edge of the transparent sheet that is opposite said one edge, which mating element can be coupled to said first coupling element to locate the transparent sheet in superposed position on the opaque sheet and to provide uniform tension between said permanently anchored edge and said opposite edge over the area of superposition and decoupled from said first coupling element so that said transparent sheet is not under tension.
