Variably adjustable handlebar shaft as lifting mechanism in twin handlebar stems for bicycles, motor cycles etc.

摘要

The invention "variably adjustable handlebar shaft as lifting mechanism in twin handlebar stems for bicycles, motor cycles etc." offers a solution to the problem of adjusting the height of and of positioning the handlebars of a two-wheeler as required with the lowest conceivable complexity. This gives a practical gain for touring with its changing requirements for the rider's posture and with different riders (individual adaptation of the height of the handlebars). The variability is achieved by the additional introduction of a second handlebar stem, the horizontal fixing by guide grooves and elements and specific cross-sections, the vertical fixing by a locking screw or gear crank.
