Abstract
A brake or clutch lever system for a motor cycle or a pedal cycle, the lever system having a lever pivoted to a lever housing. The lever housing is pivoted to a clamping bracket and is biased by a spring into an extended position, stop members holding the lever housing in the extended position. The lever housing pivots upwardly on impact to thus minimize breakage of the lever system.
Claims19
A lever system for mounting on a handlebar of a cycle or the like, the lever system comprising
- a clamping fixture,
- a lever,
- connection means for interconnecting the clamping fixture and the lever,
- first hinge means for pivotally mounting the connection means on the clamping fixture for pivotable movement between operating and retracted positions about a first pivot axis, and
- second hinge means for pivotally mounting the lever on the connection means in a spaced-apart relation to the clamping fixture for pivotable movement about a second pivot axis, the second hinge means being oriented relative to the first hinge means to align the second pivot axis in angular non-parallel relation to the first pivot axis.
The lever system for mounting on a handlebar of a cycle or the like, the lever system comprising
- a lever,
- a clamping fixture formed to include an inner wall defining a handlebar-receiving passageway having a central axis extending therethrough,
- a lever housing,
- first hinge means for mounting the lever housing on the clamping fixture for pivotable movement about a first pivot axis aligned in substantially parallel relation to the central axis of the handlebar-receiving passageway, and
- second hinge means for mounting the lever on the lever housing for pivotable movement about a second pivot axis, the second hinge means being oriented non-parallel relative to the first hinge means to define a predetermined angle between the first and second pivot axes.
A spring-back lever system for mounting on a handlebar of a cycle or the like, the lever system comprising
- lever means for operating a cable,
- a lever housing,
- first pivot means for pivotally coupling the lever means to the lever housing,
- a clamping member having means for clamping to a selected portion of the handlebar,
- a return spring acting between the lever housing and the clamping member,
- second pivot means for pivotally coupling the lever housing to the clamping member, the second pivot means having a second pivot axis extending generally non-parallel to a first pivot axis of said first pivot means, and
- stop means interconnecting the lever housing and the clamping member for locating the lever housing in an operating position, whereby the lever housing can deflect to a retracted position about said second pivot means against the bias of the return spring.
The spring-back lever system for mounting on a handlebar of a cycle or the like, the lever system comprising
- a lever assembly.
- a clamping fixture formed to include an inner wall defining a handlebar-receiving passageway having a central axis extending therethrough,
- first hinge means for mounting the lever assembly on the clamping fixture for pivotable movement between a retracted position and an operating position about a first pivot axis aligned in substantially parallel relation to the central axis of the handlebar-receiving passageway, and
- return spring means acting between the clamping fixture and the lever assembly for yieldably biasing the lever assembly from its retracted position toward its operating position so that the lever assembly is returned to its operating position following a retraction-inducing impact to the lever assembly wherein the lever assembly includes a lever, a lever housing, and a second hinge means for mounting the lever on the lever housing for pivotable movement about a second pivot axis, and the second hinge means is oriented non-parallel relative to the first hinge means to align the second pivot axis in angular relation to the first pivot axis.
