ABSTRACT:
BACKGROUND
A crayon or lumber crayon, is commonly used by craft persons, such as carpenters, loggers, metal workers, lumber graters and others. These workers frequently carry a crayon on their person in order to mark dimensions, instructions, cutting lines and other information on a work piece. Frequently field conditions and the general environment are rough. The crayons must be stored in tool pouches, pockets, nail bags and the like. The soft crayon material is often broken or ground to small pieces by contact with the nails, tools or other solid items, leaving useless remnants of crayon. Without a holder, the entire crayon is exposed to abuse.
For the foregoing reasons, there exists a need for a rugged-body crayon holder which allows the user to adjust the length of exposed crayon tip and to retract the tip of the crayon when not in use.
SUMMARY OF THE INVENTION
What is disclosed is an adjustable holder for holding a marking means, such as a crayon, comprising an elongated housing with first and second end portions, a hollow cylindrical cavity for housing marking material and a centerline therethrough. A tubular interior portion having a threaded inner bore and an outer wall is coaxially positioned within the housing cavity. A collar adjacent to the first end portion is attached to the housing, rotatable about the centerline. Collar portion has a hole for insertion of the crayon therethrough. There is provided means for exposing the tip of the crayon by advancing the crayon along the longitudinal centerline within the housing. A receptacle portion is coaxially positioned within the tubular interior portion for retentively receiving one end of the crayon. The crayon is rotated by rotation of the collar, which cooperate to linearly traverse the receptacle portion within the tube threaded bore along the centerline.
A second movement means, a slide portion, is attached to the outer wall of the tubular interior portion. The slide portion extends through a slot in the housing and is movably positioned to permit the slide portion to slide in a direction parallel with the centerline and at least a portion of the length of the hollow cavity, the tube having a longitudinal dimension less than that of the cavity.
It is therefore an object of the present invention to provide a plastic device for holding a lumber crayon.
A further object of the present invention is to provide a device in which a crayon is secured within a protective holder by a rubber ring, and the length adjustable by means of a rotatable collar or a thumb slide.
Another object of the present invention is to provide a retractable crayon holder.
Yet another object is to provide a crayon holder which includes a rotating collar that allows a consumer to advance the crayon for use and to retract it for storage.
Another object is to provide an efficient, simple design for ease of operation and manufacturing.
