An auxiliary handlebar assembly is provided. The auxiliary handlebar assembly includes an auxiliary handlebar having an open end and a coupler secured in the open end. The coupler includes a sleeve for engagement with a handlebar stem disposed on one end and a wedge shaped portion formed on the opposing end and engaged in the open end of the auxiliary handlebar. A bolt is engaged through the sleeve and the wedge shaped portion for engagement with a wedge member, such that the wedge member is caused to move radially outward for engagement with the auxiliary handlebar. In this manner, the auxiliary handlebar can be easily fixed to a handlebar stem by the coupler and a bent section of the auxiliary handlebar can be rotatably adjusted relative to a longitudinal axis of the coupler.

DETAILED DESCRIPTION The primary objective of the present invention is to provide an auxiliary handlebar assembly in which the auxiliary handlebar can be adjusted and rotated about the longitudinal axis thereof.
In accordance with one aspect of the invention, there is provided an auxiliary handlebar assembly comprising an auxiliary handlebar having a longitudinal axis and an open end, a coupler having a sleeve for engagement with a handlebar stem and a wedge shaped portion engaged in the open end of the auxiliary handlebar and a wedge member engaged in the open end of the auxiliary handlebar and engaged with the wedge shaped portion of the coupler.
The sleeve includes an end portion, and a bolt engaged through the end portion of the sleeve, the bolt being engaged with the wedge shaped portion and wedge member.
The wedge member is caused to move radially outward to engage with the auxiliary handlebar when the bolt is threaded into place, such that the auxiliary handlebar is fixed to the handlebar stem by the coupler.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.
