Abstract

An improved design drawing device for drawing amorphous patterns is disclosed. The drawing device contains a segmented flexible guide comprised of segments covered with a soft plastic or rubber or rubber type surface piece. The segments each consist of a male ratchet and a female ratchet, which snap together, wherein the size of the designs created are determined by the number of segments used to create the design. When the segments are attached together, they ratchet relative other so as to lock their positions in place. The drawing device also comprises at least one solid wheel disk which is rotatable about the inner circumference wall of the segmented flexible guide, and at least one hole through the solid wheel disk through which a drawing implement is positionable, wherein the solid wheel disk is rotatable about the inner circumference wall or outer circumference wall of the segmented flexible guide when the drawing implement is positioned through the hole positioned through the solid wheel disk, thereby forming a patterned drawing. As the wheel disk revolves around the inner surface of the segmented flexible guide, the teeth of the wheel disk enter the surface of the segmented flexible guide at right angles to lock into the surface of the segmented flexible guide.

Dependent claims

A design drawing device comprising:

a flat surface;
at least one segmented flexible guide, said segmented flexible guide comprising a plurality of interconnecting segments forming said segmented flexible guide, said segmented flexible guide having an outer circumference wall and an inner circumference wall, said segmented flexible guide being bendable into any desired shape;
at least one wheel disk, said solid wheel disk having sides, a flat top surface, a flat bottom surface, and teeth positioned on the sides of said wheel disk, said flat top surface and said flat bottom surface being perpendicular to said sides;
at least one hole through said wheel disk, said opening positioned perpendicular through and to said flat top surface and said flat bottom surface;
and
a drawing implement, said drawing implement positionable through said at least one hole positioned through said solid wheel disk;
wherein said solid wheel disk is rotatable about the inner circumference wall or outer circumference wall of said segmented flexible guide when said drawing implement is positioned through said at least one hole positioned through said solid wheel disk, thereby forming a patterned drawing, and wherein said solid wheel disk is rotatable about the inner circumference wall said segmented flexible guide, and said teeth of said wheel disk lock into the inner circumference wall of the segmented flexible guide, thereby preventing slippage of said wheel disk as said wheel disk rotates about said inner circumference wall of said segmented flexible guide.
