ABSTRACT:
A compressible finger gripping device for assembly with the surface portion of an article such as a writing instrument or a shaving instrument or the like. The device includes a substantially cylindrical body formed of a compressible, elastomeric material and defined by a substantially uniform OD and ID along the axial length of the body. A plurality of ribs arranged substantially parallel to the longitudinal axis of the body and substantially equidistantly spaced apart from each other are carried about the I.D. The combination of the selected compressible material, the selected I.D. and OD dimensions of the body and the selected number, depth and thickness of the ribs cooperate and converge to provide a compressibility index (CI) valve for the device between about 1000 to about 18,000 gms/cm.
