BACKGROUND OF THE INVENTION

1. Technical Field

This invention relates to crayons and, more particularly, to triangular shaped crayons and associated means for storage.

2. Prior Art

Various well known writing instruments have found common use and appeal. Examples include conventional hexagon cross-sectional pencils shaped to reduce unintended rolling and slippage, and round cross-sectional pens having polymeric slip reducing materials for the shells thereof and having cap clips for reducing rolling and for attaching to pockets. Generally, these designs have not been as ergonomically well designed for prolonged periods of use based on the way that such pencils and pens are conventionally held during extended writing periods. Additionally, many of these prior pens have a tendency to roll on desk tops due to their round shape.

At present, crayon users only utilize 50% of a crayon due to breakage or difficulty in handling the crayon after it has been used for a short period of time. This makes the use of crayons uneconomical since most of the crayon normally is not used. Furthermore, a mess is created whenever a crayon is accidentally stepped on after rolling on to the floor. Inasmuch as crayons are so widely used by people of all ages, it is highly desirable to improve the structure of the body of the crayon so that it can be more readily held in an untiring manner by the fingers of the hand of the user.

Prior attempts to improve the ergonomic designs of such writing utensils have for example lead to the use of various scooped portions for receiving the index finger or have lead to non-uniform curvatures. For pencils and crayons, the bodies of which are consumed during use, the use of a non-uniform shape would undesirably result in frequently changing grip configurations following sharpening. Also, various ergonomic pencil configurations would not be suitable for being sharpened in conventional pencil sharpeners. At present, the prior art is crowded with attempts to overcome such shortcomings.

The non-uniform design of some of these designs could result in inefficient packaging; some of the uniform designs do not provide for ease in picking up the writing utensil from a resting position; and some of the spiral designs are too tightly wound to provide for comfortable long term writing.

Accordingly, a need remains for an improved design for crayons and means to maintain the integrity of such a design. The present invention satisfies such a need by providing a triangular shaped crayon. Additionally, a carrying case including an adapted sharpening mechanism is provided for storage purposes. The improved shape of the present invention allows children of all ages to better grip the crayon and therefore improve drawing ability.

BRIEF SUMMARY OF THE INVENTION

In view of the foregoing background, it is therefore an object of the present invention to provide crayons and an associated carrying case. These and other objects, features, and advantages of the invention are provided by a kit for housing drawing utensils that can be supported on an inclined surface that includes a container having a substantially rectangular shape. The container is provided with a plurality of sides sized and shaped for defining a plurality of bifurcated and isolated chambers horizontally disposed along a longitudinal plane. Such a container includes an open top end portion and a closed bottom end portion. The container further includes a flap adjustably attached to the top end portion that is movable between open and closed positions.

One of the chambers is disposed adjacent the lower end portion and has a longitudinal axis extending perpendicular to the longitudinal plane. Such a chamber has axially opposed end portions equally spaced apart from a center of the container wherein one of the chamber's end portions is provided with an aperture and another of the chamber's end portions includes a cap threadably engageable therewith and detachable from the one chamber. Such a cap is preferably provided with a centrally disposed notch for assisting a user to remove the cap from the container. The one chamber's end portion that includes the aperture also preferably includes a rotatable flange member positioned therein for assisting a user to adjustably position the crayons adjacent the blade, which is disposed adjacent the one chamber end portion (discussed hereinbelow).

The present invention includes a plurality of elongated crayons longitudinally positionable into another of the chambers and maintained above the one chamber. The crayons have a wax-like core and a paper-like outer layer coated thereabout. Such crayons further have a plurality of integral faces equidistantly spaced apart from a centrally disposed longitudinal axis thereof respectively. The crayon faces preferably define a plurality of angles therebetween with each of the angles equaling approximately 60 degrees. Therefore, the crayons have substantially triangular cross-sections for defining an isometric shape.

Accordingly, each of the faces define a sufficient surface area for engaging a support surface and advantageously maintaining the crayon at a substantially stable position so that when the crayon is axially rotated along a radial path alternate ones of the faces will engage the support surface and maintain sufficient frictional contact therewith. Each of the crayons further have a body and a converging end portion axially extending away therefrom for engaging a writing surface.

Advantageously, the present invention further includes a mechanism for sharpening the crayons wherein the sharpening mechanism is disposed within one chamber and subjacent another chamber. Such a sharpening mechanism preferably includes a blade secured to one of the sides disposed within one chamber. The blade has an angled tip extending obliquely to the crayon axis wherein the crayon is longitudinally positionable into one chamber for engaging the blade. Additionally, the blade has a length extending upwardly from one side and protruding into a longitudinal path of the crayons during operating conditions.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which a preferred embodiment of the invention is shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiment set forth herein. Rather, this embodiment is provided so that this application will be thorough and complete, and will fully convey the true scope of the invention to those skilled in the art. Like numbers refer to like elements throughout the figures.

The apparatus of this invention is referred to generally in FIGS. 1–6 by the reference numeral 10 and is intended to prevent the loss or destruction of a crayon and maintain the integrity of the crayon structure. It should be understood that the apparatus 10 may be offered in a variety of colors and sizes.

Referring initially to FIG. 1, the apparatus 10 includes a container 20 having a substantially rectangular shape. The container 20 is provided with a plurality of sides sized and shaped for defining a plurality of bifurcated and isolated chambers 30a and 30b horizontally disposed along a longitudinal plane. Such a container 20 includes an open top end portion 21 and a closed bottom end portion 22. The container 20 further includes a flap 23 adjustably attached to the top end portion 21 that is movable between open and closed positions.

Now referring to FIG. 5, one chamber 30a is disposed adjacent the lower end portion 22 and has a longitudinal axis extending perpendicular to the longitudinal plane. Such a chamber 30a has axially opposed end portions equally spaced apart from a center of the container 20 wherein one of the chamber's end portions 31 is provided with an aperture 32 and another of the chamber's end portions 33 includes a cap 34 threadably engageable therewith and detachable from the chamber 30a.
