Abstract
Abstract A writing instrument is provided with a manual gripping device adjacent the writing point which comprises a resilient finger gripping portion of the assembly having a tubular sleeve enveloping the resilient portion. The resilient portion comprises an elongated tube, and a plurality of elongated slots formed therein extending axially with respect to the writing instrument barrel assembly over substantially the length of the resilient portion. The resilient portion may be a portion of the writing instrument barrel assembly, or the resilient portion and sleeve may be in the form of a separate unit which is installed over the barrel assembly.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
120 words
A writing instrument comprising: a cylindrical barrel assembly having means for retaining a writing medium disposed at one end thereof; a resilient portion of said barrel assembly disposed adjacent said barrel one end and terminating at said retaining means; and a unitary tubular sleeve enveloping said barrel resilient portion; said resilient portion comprising a thin wall elongated tube formed of a pair of bands having a continuous circumferential surface disposed one at each end thereof and a plurality of elongated slots formed thereon extending axially with respect to said cylindrical barrel assembly between said bands, whereby said tubular sleeve and said barrel resilient portion combine to provide a compressible finger grip to the user of the writing instrument during operation.
Claim 2
Dependent Claim
120 words
A writing instrument comprising: a cylindrical barrel assembly having means for retaining a writing medium disposed at one end thereof; a resilient portion of said barrel assembly disposed adjacent said barrel one end and terminating at said retaining means; and a unitary tubular sleeve enveloping said barrel resilient portion; said resilient portion comprising a thin wall elongated tube formed of a pair of bands having a continuous circumferential surface disposed one at each end thereof and a plurality of elongated slots formed thereon extending axially with respect to said cylindrical barrel assembly between said bands, whereby said tubular sleeve and said barrel resilient portion combine to provide a compressible finger grip to the user of the writing instrument during operation.
Claim 3
Dependent Claim
23 words
A writing instrument as set forth in claim 1 wherein said resilient portion of said tubular sleeve is fabricated of an acetal material.
Claim 4
Dependent Claim
27 words

Claim 12
Independent Claim
114 words
A method of fabricating a writing instrument having a cylindrical barrel assembly with a means for retaining a writing medium disposed at one end thereof which includes the steps of: providing an elongated tube having a plurality of elongated slots formed therein over substantially the length of the tube to form a plurality of resilient beams; placing said elongated tube within a tubular sleeve having an internal diameter providing contact engagement with the external surface of said elongated tube; and sliding said elongated tube and said tubular sleeve over said means for retaining a writing medium to a point on said barrel assembly where said elongated tube is radially spaced from said barrel assembly.
Claim 13
Independent Claim
114 words
A method of fabricating a writing instrument having a cylindrical barrel assembly with a means for retaining a writing medium disposed at one end thereof which includes the steps of: providing an elongated tube having a plurality of elongated slots formed therein over substantially the length of the tube to form a plurality of resilient beams; placing said elongated tube within a tubular sleeve having an internal diameter providing contact engagement with the external surface of said elongated tube; and sliding said elongated tube and said tubular sleeve over said means for retaining a writing medium to a point on said barrel assembly where said elongated tube is radially spaced from said barrel assembly.
Claim 14
Dependent Claim
18 words
