Abstract
A handlebar assembly including a pair of handgrip portions extending outwardly from a mounting portion and configured for generally vertical, arcuate movement relative to the mounting portion. One or more shock absorbing arrangements may be provided to produce a force tending to resist downward movement of the handgrip portions. Desirably, the handgrip portions are adjustable in height relative to the mounting portion.
Claims22
A vehicle handlebar assembly, comprising:
- a mounting portion configured to be connected to a front steering assembly of a vehicle;
- an elongated, first handgrip portion, wherein said first handgrip portion is pivotally connected to said mounting portion at a first pivot assembly and is a tubular member extending outwardly from said mounting portion and supporting a handgrip on an outer end thereof, said tubular member and said handgrip being coaxial, said first pivot assembly substantially constraining movement of said first handgrip portion and said handgrip to vertical, arcuate movement about a first single pivot axis, said first pivot assembly comprising a front protruding portion and rear protruding portion defining a first space therebetween and a first shaft positioned within the first space and supporting the first handgrip portion;
- an elongated, second handgrip portion, wherein said second handgrip portion is pivotally connected to said mounting portion at a second pivot assembly and is a tubular member extending outwardly from said mounting portion and supporting a handgrip on an outer end thereof, said tubular member and said handgrip being coaxial, said second pivot assembly substantially constraining movement of said second handgrip portion and said handgrip to vertical, arcuate movement about a second single pivot axis, said second pivot assembly comprising a front protruding portion and rear protruding portion defining a second space therebetween and a second shaft positioned within the second space and supporting rip portion;
- a first stop and a second stop, said first stop being configured to limit upward movement of said first handgrip portion and said second stop being configured to limit upward movement of said second handgrip portion;
- and
- at least one shock absorber configured to provide a force resisting downward movement of said first and second handgrip portions;
- and
- at least one crossbar extending between said first pivot assembly and said second pivot assembly and positioned outside of said first space and said second space;
- wherein said first pivot assembly is separate from said second pivot assembly and wherein said mounting portion extends between said first pivot assembly and said second pivot assembly, said mounting portion having a first tubular end portion and a second tubular end portion, said first tubular end portion rotationally and axially fixed to said first pivot assembly such that said first tubular end portion supports said first pivot assembly and said second tubular end portion rotationally and axially fixed to said second pivot assembly such that said second tubular end portion supports said second pivot assembly at a location spaced from said first pivot assembly in a direction of an axis of said first tubular end portion and said second tubular end portion.

A handlebar assembly, comprising:
- a mounting portion configured to be connected to a front steering assembly of a vehicle;
- a first pivot assembly supported by said mounting portion and comprising a front protruding portion and a rear protruding portion defining a first space therebetween and a first support shaft defining a first pivot axis positioned within said first space;
- a second pivot assembly supported by said mounting portion and comprising a front protruding portion and a rear protruding defining a second space therebetween and a second support shaft defining a second pivot axis positioned within said second space;
- an elongated, first handgrip portion supported on said first pivot assembly and extending outwardly from said mounting portion, said first handgrip portion substantially constrained to vertical, arcuate movement relative to said mounting portion about a single axis defined by said first pivot axis;
- an elongated, second handgrip portion supported on said second pivot assembly and extending outwardly from said mounting portion, said second handgrip portion substantially constrained to vertical, arcuate movement relative to said mounting portion about a single axis defined by said second pivot axis;
- at least one rigid crossbar extending between said first pivot assembly and said second pivot assembly and positioned outside of said first space and said second space;
- a first shock absorber configured to provide a force resisting downward movement of said first pivot assembly;
- a second shock absorber configured to provide a force resisting downward movement of said second pivot assembly;
- a first stop configured to limit an upward movement of said first pivot assembly;
- and
- a second stop configured to limit an upward movement of said second pivot assembly.

A handlebar assembly for steering a vehicle, comprising:
- a mounting portion configured to be connected to a front steering assembly of a vehicle;
- a first support extending vertically upward from said mounting portion, said first support including a front protruding portion and a rear protruding portion spaced apart from one another to define a first space therebetween, said pair of protruding portions comprising an opening defining a first pivot axis that is spaced above said mounting portion;
- a first shaft supported within said opening of said first support and positioned within said first space;
- a first pivot body rotatably supported on said first shaft, a portion of said pivot body positioned between said pair of protruding portions of said first support;
- a first handgrip portion, said first handgrip portion including a single elongate, tubular member carried by said first pivot body and extending outward from said first support, an outer end portion of said first handgrip portion configured to receive a handgrip, wherein said first handgrip portion and said first pivot body are rotatable together relative to said first support about a single pivot axis defined by said first pivot axis;
- a first shock absorber operably positioned between said first pivot body and said first support, said first shock absorber providing a force tending to resist downward movement of said first handgrip portion;
- a second support extending vertically upward from said mounting portion and spaced from said first support, said second support including a front protruding portion and a rear protruding portion spaced apart from one another to define a second space therebetween, said pair of protruding portions comprising an opening defining a second pivot axis that is spaced above said mounting portion;
- a second shaft supported within said opening of said second support and positioned within said second space;
- a second pivot body rotatably supported on said second shaft, a portion of said pivot body positioned between said pair of protruding portions of said second support;
- a second handgrip portion, said second handgrip portion including a single elongate, tubular member carried by said second pivot body and extending outward from said second support, an outer end portion of said second handgrip portion configured to receive a handgrip, wherein said second handgrip portion and said second pivot body are rotatable together relative to said second support about a single pivot axis defined by said second pivot axis;
- a second shock absorber operably positioned between said second pivot body and said second support, said second shock absorber providing a force tending to resist downward movement of said second handgrip portion;
- at least one crossbar extending between said first support to said second support, wherein said at least one crossbar is a separate component from said first handgrip portion and said second handgrip portion, and wherein said at least one crossbar is positioned outside of said first space and said second space.
