US 5,000,599 A · Writing implement

Abstract

A writing implement or the like is provided with a deformable grip for shape conformance in accordance with anatomical contours of the individual user, thereby providing enhanced user comfort with minimum fatigue during use. The deformable grip is located on the body of a writing implement in a position for grasping with the user's fingertips during normal use of the writing implement. The deformable grip is adapted to undergo substantial localized deformation in response to light manual pressure applied by the user's fingertips to conform geometrically with the shape of the user's fingertips in a custom fit manner, thereby providing a highly comfortable grip with a unique, novelty feel. The deformable grip is further adapted for retention of the deformed geometry for at least a substantial period of time, for example, at least about five seconds or more.

Dependent claims

A writing implement, comprising:

an implement body;
a marking medium carried by said implement body and including a writing tip;
and
a deformable grip on said implement body in a position for manual grasping by a writer during use of said writing implement, said grip including means responsive to said manual grasping for changing the shape of said grip from an initial shape to a custom fit shape conforming substantially with the anatomical coutours of the writer's fingertips for enhanced comfort and reduced fatigue during use of the writing implement, said shape changing means retaining said custom fit shape for at least about five seconds following release of said grip by the writer and thereafter returning substantially to said initial shape.
