Abstract

Abstract A finger gripping device used as a removable attachment to a writing implement is formed as a one piece cylindrical body member made of flexible material. The body has an internal bore of uniform diameter so that it may be slid onto a writing implement. A plurality of circumferential ribs are axially spaced along the outside surface of the cylindrical body. The ribs are formed by closely spaced peaks and valleys.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 219 words
A finger-gripping device for use as a removal attachment to a writing implement comprising a one piece cylindrical body member made of flexible material, and said cylindrical body member having an internal bore of uniform diameter along the entire length of said cylindrical body member, a plurality of circumferential ribs axially spaced along the outside surface of said cylindrical body member forming a finger supporting surface when said cylindrical body member is carried on a writing implement, each said circumferential rib lying in a plane perpendicular to the axis of said cylindrical body member, each said plane being equally spaced between adjacent planes and parallel to each other plane, said ribs formed by closely spaced peaks and valleys interposed between said peaks, the outside diameter of each of said peaks of each of said circumferential ribs being the same so that said gripping device is of uniform size, and six raised longitudinally extending ribs oriented in parallel with each other and parallel to the longitudinal axis of said cylindrical body member being equally spaced apart along the inside surface of said cylindrical body member, each of said raised longitudinally extending ribs being of uniform height throughout its length, said height of each raised longitudinally extending rib being the same as the height of each other raised longitudinally extending rib.
Claim 2
Dependent Claim 219 words
A finger-gripping device for use as a removal attachment to a writing implement comprising a one piece cylindrical body member made of flexible material, and said cylindrical body member having an internal bore of uniform diameter along the entire length of said cylindrical body member, a plurality of circumferential ribs axially spaced along the outside surface of said cylindrical body member forming a finger supporting surface when said cylindrical body member is carried on a writing implement, each said circumferential rib lying in a plane perpendicular to the axis of said cylindrical body member, each said plane being equally spaced between adjacent planes and parallel to each other plane, said ribs formed by closely spaced peaks and valleys interposed between said peaks, the outside diameter of each of said peaks of each of said circumferential ribs being the same so that said gripping device is of uniform size, and six raised longitudinally extending ribs oriented in parallel with each other and parallel to the longitudinal axis of said cylindrical body member being equally spaced apart along the inside surface of said cylindrical body member, each of said raised longitudinally extending ribs being of uniform height throughout its length, said height of each raised longitudinally extending rib being the same as the height of each other raised longitudinally extending rib.
Claim 3
Dependent Claim 23 words
The finger-gripping device according to claim 1 wherein said peaks forming said circumferential ribs are spaced approximately one eighth of an inch apart.
Claim 4
Dependent Claim 26 words
The finger-gripping device according to claim 2 further comprising a first flat surface extending the entire length of said body member on the outside surface thereof.
Claim 5
Dependent Claim 39 words
The finger-gripping device according to claim 3 further comprising a second flat surface extending the entire length of said body member on the outside surface thereof, said first and second flat surfaces lying in planes parallel to each other.
Claim 6
Dependent Claim 62 words
The finger-gripping device according to claim 1 further comprising a slit longitudinally extending along said body member parallel to the central axis thereof and through the full thickness of the wall of said cylindrical body member, the material of said body member being sufficently resilient so that said body member may function as a paper clip to hold objects within said slit.
