Abstract

A gripping element, particularly to writing instruments having a gripping element, which more specifically relates to a marker having a gripping element over a central region thereof. Such positioning of the gripping element facilitates use of the writing instrument in other than standard writing grasps. For example, the positioning of a gripping element over the central region of a writing instrument facilitates gripping of the writing instrument when writing on vertical or inverse horizontal (i.e. upside down) planes. The gripping element has a plurality of elevated sections in the form of intercalated crosses and hexagons or sliced hexagons. The elevated sections may be smooth or textured to enhance gripping and to reduce slippage of the writing instrument during use.

Claims (32)

1. A writing instrument comprising:

an elongated writing instrument body having a first end, a second end, and a central region encompassing a midpoint substantially equidistant from said first end and said second end;

a writing nib at said first end;

a gripping section arranged along said central region of said writing body and used for gripping said instrument during select writing uses; and

a substantially cylindrical elastomeric gripping element positioned over and encircling said gripping section along said central region of said writing instrument body and extending at least over said midpoint and ending at a position spaced from said second end such that said gripping element is shorter than said writing instrument body,

wherein said gripping element comprises:

an outer surface; and

a plurality of elevated sections extending from said outer surface, said elevated sections being raised at least 0.1 mm above said outer surface.

2. The writing instrument of claim 1 , wherein said elevated sections have intercalated shapes.

3. A writing instrument comprising:

an elongated writing instrument body having a first end, a second end, and a central region encompassing a midpoint substantially equidistant from said first end and said second end;

a writing nib at said first end;

a gripping section arranged along said central region of said writing body and used for gripping said instrument during select writing uses; and

a substantially cylindrical elastomeric gripping element positioned over and encircling said gripping section along said central region of said writing instrument body and extending at least over said midpoint and ending at a position spaced from said second end such that said gripping element is shorter than said writing instrument body,

wherein said gripping element comprises:

an outer surface; and

a plurality of elevated sections extending from said outer surface, said elevated sections being raised at most 3.0 mm above said outer surface.

4. The writing instrument of claim 1 , wherein said outer surface of said gripping element is textured.

5. A writing instrument comprising,

an elongated writing instrument body having a first end, a second end, and a central region encompassing a midpoint substantially equidistant from said first end and said second end;

a writing nib at said first end;

a gripping section arranged along said central region of said writing body and used for gripping said instrument during select writing uses; and

a substantially cylindrical elastomeric gripping element positioned over and encircling said gripping section along said central region of said writing instrument body and extending at least over said midpoint and ending at a position spaced from said second end such that said gripping element is shorter than said writing instrument body, wherein

said writing instrument further comprises a front nose cone adjacent and proximal to said nib; and

said gripping element extends over said front nose cone of said writing instrument.

6. The writing instrument of claim 5 , further comprising a cap, wherein said front nose cone is configured to be selectively covered by said cap.

7. The writing instrument of claim 5 , wherein said gripping element has a textured outer surface.

8. The writing instrument of claim 1 , wherein said gripping element is formed from an anti-slip material.

9. The writing instrument of claim 1 , wherein said gripping element is formed from resilient material.

10. The writing instrument of claim 1 , wherein said gripping element is fabricated of a thermoplastic elastomer.

11. The writing instrument of claim 1 , wherein said writing instrument is a felt tip marker.

12. The writing instrument of claim 1 , wherein a writing tip is provided at each of said first end and said second end.
