Abstract

Abstract A double lever braking system that allows triathletes, cyclists and recreational riders the ability to control a bicycle equipped with an aerodynamic handlebar system through various situations while maintaining the aerodynamic riding position as well as in the upright stable riding position. The double lever braking system connects multiple brake levers to a common caliper type bicycle brake which allow human powered vehicles, where multiple extreme riding positions are desired, for improved performance and efficiency to be safe and controllable in various riding situations.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 427 words
A double brake lever brake actuation system for a bicycle equipped with an aerodynamic type handlebar assembly having at least two riding hand positions, an upright stable riding hand position on a first portion of said handlebar assembly and a forward aerodynamic riding hand position on a second portion of said handlebar assembly, comprising: (a.) a rear bicycle brake mounted on a rear triangle of said bicycle, which includes a pair of brak epads which are engaged on a rim of a rear wheel of said bicycle which rear wheel is located between each said brake pad to reduce the speed or stop said bicycle, (b.) two brake levers, one including a primary brake lever located on the upright stable riding hand position on said first portion of said handlebar assembly and one secondary brake lever located on the forward aerodynamic riding hand position on said second portion of said handlebar assembly, which said primary and secondary levers allow a bicycle rider to actuate said bicycle brake while remaining in said aerodymaic riding hand position as well as in said upright stable riding hand position, (c.) the brake actuation system comprising: (c1.) two brake cable and housing assemblies each connected to one end of said brake cable and housing assemblies to a corresponding one of said primary and secondary brake levers, (c2.) a single brake cable and housing assembly connected at one end thereof to said rear bicycle brake, (c3.) a rendezvous cable connector which connects said two brake cable and housing assemblies ends not connected to said primary and secondary brake levers to said single brake cable and housing assembly end not connected to said rear bicycle brake, (c4.) a double lever barrel that houses the rendezvous cable conenctor whereby said double lever barrel acts as an interface between said brake cable and housing assemblies going into said double lever barrel and said single brake cable and housing assembly going out of said double lever barrel which allow brake actuation from each said primary and secondary brake levers or combination of said brake levers thereby allowing rear brake actuation from each of said riding hand positions, (d.) individual brake lever adjustment means for each said primary and secondary brake levers tos aid rear bicycle brake comprising adjusting barrel assemblies to compensate for wear each adjusting barrel assembly being located between each said primary and secondary brake levers and said double lever barrel, which allow responsive brake actuation and ensure a tight fit between said respective brake levers, brake cable and housing assemblies and said bicycle brake.
Claim 2
Dependent Claim 427 words
A double brake lever brake actuation system for a bicycle equipped with an aerodynamic type handlebar assembly having at least two riding hand positions, an upright stable riding hand position on a first portion of said handlebar assembly and a forward aerodynamic riding hand position on a second portion of said handlebar assembly, comprising: (a.) a rear bicycle brake mounted on a rear triangle of said bicycle, which includes a pair of brak epads which are engaged on a rim of a rear wheel of said bicycle which rear wheel is located between each said brake pad to reduce the speed or stop said bicycle, (b.) two brake levers, one including a primary brake lever located on the upright stable riding hand position on said first portion of said handlebar assembly and one secondary brake lever located on the forward aerodynamic riding hand position on said second portion of said handlebar assembly, which said primary and secondary levers allow a bicycle rider to actuate said bicycle brake while remaining in said aerodymaic riding hand position as well as in said upright stable riding hand position, (c.) the brake actuation system comprising: (c1.) two brake cable and housing assemblies each connected to one end of said brake cable and housing assemblies to a corresponding one of said primary and secondary brake levers, (c2.) a single brake cable and housing assembly connected at one end thereof to said rear bicycle brake, (c3.) a rendezvous cable connector which connects said two brake cable and housing assemblies ends not connected to said primary and secondary brake levers to said single brake cable and housing assembly end not connected to said rear bicycle brake, (c4.) a double lever barrel that houses the rendezvous cable conenctor whereby said double lever barrel acts as an interface between said brake cable and housing assemblies going into said double lever barrel and said single brake cable and housing assembly going out of said double lever barrel which allow brake actuation from each said primary and secondary brake levers or combination of said brake levers thereby allowing rear brake actuation from each of said riding hand positions, (d.) individual brake lever adjustment means for each said primary and secondary brake levers tos aid rear bicycle brake comprising adjusting barrel assemblies to compensate for wear each adjusting barrel assembly being located between each said primary and secondary brake levers and said double lever barrel, which allow responsive brake actuation and ensure a tight fit between said respective brake levers, brake cable and housing assemblies and said bicycle brake.
Claim 3
Dependent Claim 34 words
The double brake lever brake actuation system of claim 1 wherein said aerodynamic type handlebar assembly is a triathlete handlebar or a type of bicycle handlebar with an aerodynamic type clamped on bar attachment.
Claim 4
Dependent Claim 36 words
The double brake lever brake actuation system of claim 1 wherein said rendezvous cable connector is cylindrically shaped which fits inside said double lever barrel whereby said rendezvous cable connector is freely rotatable inside said body.
Claim 5
Dependent Claim 99 words
The double lever brake actuation system of claim 1 further comprises an additional set of primary and secondary brake levers located at separate portions of said handlebar assembly on an opposite side of said aerodynamic type handlebar assembly for upright stable riding as well as for forward aerodynamic riding, another brake actuation system and individual brake lever adjustment system for connection of said additional two respective brake levers to a front brake, mounted on a front fork of said bicycle, which when actuated engages a set of brake pads on a rim of a front wheel of said bicycle.
