  • Patent number: 5048989
    Abstract: A crayon holder including a tubular sleeve for receiving and retaining a stick of writing material in the form of a crayon, chalk, or the like. The holder includes an inner slidable member having an opening to receive and retain one end of the stick of writing material to permit the writing material to be selectively extended outwardly from and to be retracted into one end of the sleeve. The retainer includes an outwardly extending positioning peg that is adapted to be received in a longitudinally extending slide slot formed in the sleeve. A plurality of laterally offset retaining slots are provided adjacent to and in communication with the longitudinal slide slot to permit the positioning peg to be received and retained at a desired axial position along the holder to expose a predetermined quantity of writing material and to prevent inward movement of the writing material when heavy writing pressure is applied.
