Abstract
Abstract A bicycle handlebar grip is disclosed that is adapted to fit over the "cross-over" and "turn-of-bar" segments of a racing bicycle handlebar. The grip is shaped to allow a comfortable hand grip in any of several positions. The grip also includes provisions for reducing transmission of vibration from the handlebar to the rider's hand, thus avoiding physical ailments such as "biker's nerve palsy".

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
194 words
A handlebar grip for the crossover and turn-of-bar portion of a racing bicycle handlebar in which such portion is substantially tubular about a central axis and includes (1) a substantially straight section extending laterally outward from a central portion of the handlebar, and (2) turn-of-bar section extending from the straight section forward terminating at a drop portion having a brake lower attachment location, comprising: a flexible "L" shaped body mountable on the crossover and turn-of-bar portion with a complementary annular bore extending from one end to an opposite end to receive the crossover and turn-of-bar portion therein; said "L" shaped body having (1) a crossover segment extending from the one end along the substantially straight section and (2) a turn-of-bar segment extending from the crossover segment forward to the drop portion terminating at the brake lever attachment location; said turn-of-bar segment having an elbow projection formed integrally therewith that projects outward from the central axis to enlarge the turn-of-bar segment and provide support for the heel portion of the biker's hand independently of whether the biker grips the crossover segment in an overhand grip or grips the turn-of-bar section in a side underhand grip.
Claim 2
Dependent Claim
194 words
A handlebar grip for the crossover and turn-of-bar portion of a racing bicycle handlebar in which such portion is substantially tubular about a central axis and includes (1) a substantially straight section extending laterally outward from a central portion of the handlebar, and (2) turn-of-bar section extending from the straight section forward terminating at a drop portion having a brake lower attachment location, comprising: a flexible "L" shaped body mountable on the crossover and turn-of-bar portion with a complementary annular bore extending from one end to an opposite end to receive the crossover and turn-of-bar portion therein; said "L" shaped body having (1) a crossover segment extending from the one end along the substantially straight section and (2) a turn-of-bar segment extending from the crossover segment forward to the drop portion terminating at the brake lever attachment location; said turn-of-bar segment having an elbow projection formed integrally therewith that projects outward from the central axis to enlarge the turn-of-bar segment and provide support for the heel portion of the biker's hand independently of whether the biker grips the crossover segment in an overhand grip or grips the turn-of-bar section in a side underhand grip.
Claim 3
Dependent Claim
42 words
The handlebar grip as defined in claim 1 wherein the elbow projection projects outward from the turn-of-bar segment and extends inwardly in one direction substantially tangential to the crossover segment and extends forward in another direction substantially tangential with the turn-of-bar section.
Claim 4
Dependent Claim
38 words
The handlebar grip as defined in claim 1 wherein the radial distance of the projection from the center axis progressively decreases from an apex toward the crossover segment and progressively decreases from the apex toward the turn-of-bar segment.
Claim 5
Dependent Claim
51 words
The handlebar grip as defined in claim 1 wherein the elbow projection has an upper surface and includes a flexible wall that extends radially outward and rearward with the wall having a base that intersects substantially tangentially with the upper surface to receive and support the heel of the palm thereon.
Claim 6
Dependent Claim
54 words
The handlebar grip as defined in claim 1 wherein the elbow projection comprises a flexible wall that extends outward and rearward from the center axis in a cantilever fashion to flex in response to forces applied thereto to dampen and minimize the transmission of vibration from the handlebar to the palm of the hand.
Claim 7
Dependent Claim
33 words
The handlebar grip as defined in claim 5 wherein the elbow projection further includes flexible ribs that extend radially outward supporting and stiffening the flexible wall to prevent the wall from collapsing downward.
Claim 8
Dependent Claim
92 words
The handlebar grip as defined in claim 1 wherein the crossover segment includes (1) an annular wall extending along the straight section and (2) a plurality of annular ribs spaced at intervals along the crossover segment to normally support the annular wall radially spaced from the straight section of the handlebar in which the spacing between the ribs corresponds with the distance between the fingers to permit the biker to squeeze the wall and deflect the wall intermediate the ribs to form temporary finger indentations to minimize lateral sliding of the hand.
Claim 9
Dependent Claim
42 words
The handlebar grip as defined in claim 1 wherein the turn-of-bar segment has a flexible flange at the brake lever attachment location to receive the support the biker's thumb tip when the biker grips the turn-of-bar segment in a side underhand grip.
