Abstract
Abstract A touring bicycle handlebar and reversible brake adaptor lever comprising of a handlebar having straight bar lengths extending equidistantly on each side of the handlebar boss providing the cyclist with the means to assume a hands on semicrouched posture, each straight bar length terminated by bent portions extending the bar upwardly above the level of the first straight portions to second straight portions with further bent portions extending the bar forwardly and downwardly, providing the cyclist with the means to assume a hands on upright posture, with third straight portions providing a means for mounting the brake lever assemblages, the third straight portions terminated by bending the bar backwardly to provide straight portions that extend beyond and below the first straight portions providing the cyclist the means to assume a hands on crouched posture and of a brake lever to replace the levers of the drop racing handlebar brake assemblages permitting the mounting of the modified assemblages on the touring handlebar so as to project toward the cyclist with the lever handle paralleling the straight bar length portions at the level of the handlebar boss where they can be grasped simultaneously for brake operation. The resultant positioning of the brake adaptor lever centrally in the assemblage mounting bracket minimizes the operational stress on the mechanism and permits the projection of the assemblage toward the cyclist reducing the required size of the lever to a minimum.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
199 words
A combination bicycle touring handlebar and brake lever for mounting on a bicycle handlebar stem, said handlebar consisting of a boss with a first straight length of bar having portions equidistantly on each side of the boss, these first straight portions permitting the cyclist to assume a hands on semicrouched posture, each of the straight length portions terminating at first bent portions, said first bent portions projecting the bar upwardly above the level of the boss to connect to second straight portions, the bar further including a second set of bent portions for curving the bar forwardly and downwardly to third staight portions providing mounting means for brake lever assemblages, said second bent portions permitting the cyclist to assume a hands on upright posture, said third straight portions terminating below said boss at third bent portions, the bar terminating in fourth straight portions permitting the cyclist to assume a hands on crouched posture, said brake lever to replace the conventional brake lever of a brake operating assemblage installed on a conventional drop racing handlebar, forming a modified brake assemblage so as to be mounted on said touring handlebar in such a position as to provide for positive brake operation.
Claim 2
Dependent Claim
199 words
A combination bicycle touring handlebar and brake lever for mounting on a bicycle handlebar stem, said handlebar consisting of a boss with a first straight length of bar having portions equidistantly on each side of the boss, these first straight portions permitting the cyclist to assume a hands on semicrouched posture, each of the straight length portions terminating at first bent portions, said first bent portions projecting the bar upwardly above the level of the boss to connect to second straight portions, the bar further including a second set of bent portions for curving the bar forwardly and downwardly to third staight portions providing mounting means for brake lever assemblages, said second bent portions permitting the cyclist to assume a hands on upright posture, said third straight portions terminating below said boss at third bent portions, the bar terminating in fourth straight portions permitting the cyclist to assume a hands on crouched posture, said brake lever to replace the conventional brake lever of a brake operating assemblage installed on a conventional drop racing handlebar, forming a modified brake assemblage so as to be mounted on said touring handlebar in such a position as to provide for positive brake operation.
Claim 3
Dependent Claim
36 words
The combination bicycle touring handle bar and brake lever of claim 1 wherein the first bends of the handlebar are 90 degrees and terminate the first straight portions of the handlebar and extend the bar upwardly.
Claim 4
Dependent Claim
38 words
The combination bicycle touring handlebar and brake lever of claim 1 wherein the second bends of the handlebar are approximately 170 degrees and terminate the second straight portions of the handlebar and extend the bar forwardly and downwardly.
Claim 5
Dependent Claim
36 words
The combination bicycle touring handlebar and brake lever of claim 1 wherein the third bends of the handlebar are approximately 100 degrees and terminate the third straight portions of the handlebar and extend the bar rearwardly.
Claim 6
Dependent Claim
98 words
The combination bicycle touring handlebar and brake lever of claim 1 wherein all bends of the handlebar have a centre line radius of approximately the minimum permitted by the diameter of the tubing employed and where all bends are separated by a straight length of tubing sufficient to produce a configuration that is symmetrical about the transverse centre line of the handlebar boss with an overall width of approximately sixteen inches and with an overall height of approximately twelve inches, said handlebar extending approximately equidistantly above and below the level of the first straight portions of the handlebar.
Claim 7
Dependent Claim
45 words
The combination bicycle touring handlebar and brake lever of claim 1 wherein the brake lever consists of a unit of cast, moulded or machined metal in the form of a bent two pronged fork, the fork prongs are symmetrical so as to provide for reversibility.
Claim 8
Dependent Claim
109 words
The combination bicycle touring handlebar and brake lever of claim 1 wherein the brake lever consists of two prongs with a space separation of the prongs fixed by a solid metal stabilizer and a brake handle bent approximately 80 degrees to create an inside angle with the prong face of approximately 100 degrees, said prongs are provided with holes of approximately seven sixteenth inch diameter to receive a standard pivotal lever shaft and nonmetallic bearings for installation in a conventional brake assemblage bracket, said prongs are further provided with semicircular notched saddles to receive a detached standard brake cable connection collar obtainable from the displaced vertical main brake lever.
Claim 9
Dependent Claim
67 words
The combination bicycle touring handlebar and brake lever of claim 1 wherein the modified brake operating assemblage is mounted on the inside face of the third straight portion of the touring handlebar between the second and third bends projecting the brake assemblage back toward the cyclist where both the brake lever handle and the first straight portion of the handlebar can be grasped simultaneously for brake operation.
