ABSTRACT:
A handle for a manually movable vehicle or other article, such as a stroller, is infinitely adjustable to enable the person or persons imparting motion to the vehicle to achieve the greatest leverage and/or comfort. A height-adjustment assembly is disposed between and interconnects each extension rod and handlebar of the handle. The height-adjustment assembly includes a plurality of clutch plates and a locking lever having a cam end. The locking lever is manually moved between a locked position in which the lever cam end causes abutment of and friction between the clutch plates thereby preventing relative movement of the plates and securing the handlebar at a selected height, and an unlocked position in which the lever cam end reduces friction between the clutch plates so that the plates are movable relative to one another to enable pivotal movement and height adjustment of the handlebar.
