Embodiment Construction

[0028] figure 2 is a schematic illustration of writing instrument 20 having a writing portion 30 , a gripping portion 32 and a stabilizing portion 34 . The writing instrument 20 reduces pressure and writing fatigue by providing a holding portion 32 with a substantial thickness, prevents the user from gripping the holding portion 32 of the writing instrument 20, and provides a substantially conforming hand such as the index finger or the middle finger of a human hand, or substantially Surface 22 conforms to the contours of portions of both the index and middle fingers. Grip portion 32 is generally symmetrical about a plane substantially perpendicular to contoured surface 22 so that writing instrument 20 can be used by a right-handed or left-handed person. Two examples similar to writing implement 20 are shown in Figures 10-14 (first example) and Figures 15-19 (second example).

[0029] The writing instrument 20 can be used with a contoured surface 22 against such as image 3...

Abstract

An ergonomic writing instrument has a writing section, a grasping section, and a stabilizing section. The writing instrument reduces stress and writing fatigue by providing the grasping section with a substantial thickness to keep users from clenching and a surface with a contour that essentially fits a portion of a hand, such as either the index finger or the middle finger of the left and right human hand or that essentially fits portions of both the index finger and middle finger. The grasping section is generally symmetrical about a plane essentially normal to the contoured surface so that the writing instrument can be used by either a right handed person or a left handed person.

Description

[0001] This application claims priority from United States Provisional Patent Application No. US 60 / 213,306, filed June 22, 2000. technical field [0002] The present invention relates to an ergonomic writing instrument, especially an ergonomic writing instrument that fits various parts of a human hand and can be used separately by the left hand and the right hand. Background technique [0003] A number of approaches have been taken over the years to develop writing implements that provide a better grip to minimize the problems associated with prolonged handwriting, such as writing fatigue and callus formation; see, for example, U.S. Patent 20 Jul. 1993 US5228794 issued to Hochstetler on June 20, 1995; US5549405 issued to Krahn on August 27, 1996; US5893671 to Bellue. A concrete effective solution is the ErgoPen  Writing instrument, available from ErgoPen, Berkeley, CA  Inc. acquired, currently under the brand name Sheaffer owned by BIC Corporation of Milford, Connectic...
