Abstract
A grip accessory, especially for a writing instrucment such as for a convention pencil or pen, a cosmetics pencil or applicator, a medical instrument, or the like. The device has a core with a bore made from a material that slides relatively easily over the instrument, an aperture in the core, and an elastomeric sheath with protrusions that extend through the aperture and into the bore. The protrusions provide resistance to the sliding fo the instrument through the bore when the instrument's outer surface engages the protrusions, thereby keeping the grip accessory in place but allowing the accessory to be place on and removed from the elongate instrument.
Claims13
A grip accessory, comprising:
- a core both defining a bore adapted to removably receive an elongate instrument slid thereinto and comprising a relatively non-elastic material having a surface and an integral sheath formed over the core for providing a comfortable gripping surface and also engaging a portion of the surface of an elongate instrument in the bore.
A method for making a grip accessory, comprising:
- A. molding from a first material a core having a bore and at least one aperture;
- and
- B. molding over the core a sheath of a second, elastomeric material, having a geometry that includes at least one protrusion that extends past the aperture into the bore, wherein the first material and the second material bond during the molding process.
