  • Patent number: 5640743
    Abstract: A holder for long slender implements such as pencils and pens is disclosed. The holder comprises a support member which is preferably a thin web having opposed side surfaces. The web includes at least one opening that communicates with each of the side surfaces. Each side of the opening is surrounded by a plurality of flexible fingers which extend away from each side surface in a converging relationship so that the flexible fingers form a hollow frusto-conical shape that is preferably divided into equal segments. A long slender implement inserted through an opening in an outer end of the frusto conical shape forces the outer ends of the flexible fingers outward. The pressure exerted by the flexible fingers holds the long slender implement securely. The holder may be provided with a resilient clip, an adhesive or a magnetic base for attaching the holder to a variety of suitable surfaces.
