Abstract
Devices, kits, and methods for making a carved crayon are provided. In one aspect, a crayon carving device includes a base, a pantograph armature coupled to the base, a crayon positioner, and at least one guide template parallel to the crayon positioner. The kit may further include a wrapper removal mechanism configured to remove a wrapper from a crayon, such that the crayon carving device may be used on an exposed crayon surface.
Claims4
A wrapper removal mechanism, comprising:
- a body portion having a first surface, a second surface, an upper aspect, a lower aspect, and a width defined by the distance between the first surface and the second surface;
- a gripping outer surface at least partially coupled to the width of the body portion;
- a gripping lower edge at least partially coupled to the lower aspect of the body portion;
- an aperture extending through the width of the body portion to define an aperture inner wall, wherein a width of the aperture inner wall is equal to the width of the width of the body portion, and wherein the aperture has an upper aspect and a lower aspect, wherein the lower aspect of the aperture is located closer to the gripping lower edge than is the upper aspect of the aperture;
- and
- a rib feature having a length and a maximum height, wherein the rib feature is coupled directly to and extends outwardly from the lower aspect of the aperture inner wall, such that a distance between the rib feature and the lower aspect of the aperture is shorter than a distance between the rib feature and the upper aspect of the aperture, whereby the rib feature is configured to sunder and remove a wrapper from a crayon;
- and
- wherein the rib feature includes a first tapered section tapering from no height to the maximum height, a maximum height section having the maximum height, and a second tapered section tapering from the maximum height to a lesser height that is less than the maximum height, wherein when a length of the first tapered section, a length of the maximum height section, and a length of the second tapered section are added together collectively, the length of the rib feature is equal to the width of the aperture inner wall.

- a gripping outer surface coupled to the body portion;
- a gripping lower edge coupled to a lower aspect of the gripping outer surface;
- wherein the aperture is polygon-shaped and defines an aperture inner wall having a width equal to the width of the body portion, the aperture having a lower aspect and an upper aspect, wherein the lower aspect of the aperture is located closer to the gripping lower edge than is the upper aspect of the aperture;
- and
- a rib feature having a length and a maximum height, wherein the rib feature is coupled directly to and extends outwardly from the aperture inner wall, such that a distance between the rib feature and the lower aspect of the aperture is shorter than a distance between the rib feature and the upper aspect of the aperture;
- and
