Abstract A removable finger grip adaptable to a wide variety and size of writing instruments. The finger grip is an elongate resilient body having a triangular cross-sectional shape and a cylindrical bore coaxial with the longitudinal axis. In order to accommodate a wide variety of writing instruments, the cylindrical bore has a plurality of ribs or ridges along the entire length of the bore for gripping instruments smaller in size than the diameter of the bore. The triangular shape provides three planar surfaces for gripping the device when installed on a writing instrument and also provides a thin web of material in the planar gripping surfaces between them and the cylindrical bore at the center of the planar gripping surfaces. This thin web allows the finger grip to expand for accommodating writing instruments larger than the cylindrical bore. The resilience of the finger grip allows easy removal from one writing instrument for use with another.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
95 words
A removable finger grip for writing instruments, comprising: an elongate resilient body having a substantially triangular cross-sectional closed shape providing planar gripping surfaces; a bore extending through the center of said body; said bore being formed to provide thickened areas at the corners of said substantially triangular cross-sectional shape and a thin wall portion along the length of each planar gripping surface; a plurality of inwardly extending ridges along the length of the bore at the areas coinciding with the thickened corners; whereby said finger grip can accommodate a variety of sizes of writing instruments.
